Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, and more specifically, to a frame connector and a modular prefabricated substation module. Background Technology

[0002] Compared to traditional substations, modular prefabricated substations feature standardized design, factory manufacturing, and prefabricated construction. They can be customized to different specifications and standards for specific substation sites, and can be directly transported to the construction site for installation after manufacturing is complete.

[0003] The current manufacturing process for modular substations generally includes, in sequence, drawing design, substation fabrication, installation of internal equipment, and on-site installation. During substation fabrication, considerations must be given to the overall frame construction and wall panel installation; during internal equipment installation, the layout of heavy electrical equipment within the substation must be considered; and during on-site installation, the secure connection between the substation and the installation foundation must be ensured. Currently, there is limited mature experience or solutions available for modular substations in China, and the following issues urgently need to be addressed:

[0004] 1. During the cabin fabrication stage, to ensure the strength of the frame, it is usually constructed by splicing and welding together structural steel. Cabin substations are generally large in size and require a large amount of steel for the frame, making the welding process quite complex. Although welding robots can be used to weld the frame, another characteristic of cabin substations is that each cabin substation's frame will have some differences. This makes it difficult for welding robots to match the frames of various specifications of cabin substations. This mismatch will directly lead to some areas of the structural steel components not achieving the required fit for fine welding during the frame welding process. Furthermore, due to factors such as welding stress, the welded frame may have defects or even be defective.

[0005] In reality, not every node in the framework constructed from profiles is a critical load-bearing node. For less important steel connection points, non-welding processes such as connectors can be used for connection. However, existing technologies lack universal connectors that can effectively achieve a more stable connection between steel profiles.

[0006] On the other hand, the wall panels are usually made of non-metallic materials, so in the substation, it is also quite difficult to achieve a more stable assembly between the wall panels and the frame components.

[0007] 2. During the equipment installation phase inside the substation, after the substation body is assembled, electrical equipment such as switchgear and wiring need to be arranged in the factory. Because the substation body is a relatively enclosed space with limited internal space, conventional methods such as hoisting are difficult to apply. In particular, the individual switchgear used in substations can weigh 800-1000 kg, making manual relocation difficult. In practice, multiple switchgears need to be placed side-by-side within a single substation body, and adjacent switchgears need to be connected. Therefore, when installing switchgears inside the substation, in addition to considering the installation location, it is also necessary to consider how to accurately connect multiple switchgears. Furthermore, considering the later maintenance and commissioning of the switchgears, it is also necessary to consider how to move any switchgear from its installation location to the maintenance / commissioning location within the substation.

[0008] 3. During the on-site installation phase, the installation accuracy of the modular substation depends on the accuracy of the reserved installation positions at the cabin, the accuracy of the reserved installation positions at the installation foundation, and the design accuracy of the installation positions at the cabin and installation foundation during the design phase. In reality, the reserved installation positions at the cabin and installation foundation, as well as the design accuracy, are completed by different teams, institutions, departments, or even companies. It is virtually impossible to ensure that the errors among these three aspects are within the allowable range.

[0009] 4. Due to the concepts of intelligentization and machine-driven human operation, traditional substations are equipped with a large number of monitoring systems. However, modular substations are prefabricated in the factory. How to achieve intelligent monitoring of modular substations or connect them to the existing power monitoring system is an urgent problem to be solved. Summary of the Invention

[0010] The present invention provides a skeleton connector that can overcome some or more defects of the prior art.

[0011] According to the present invention, the frame connector includes multiple connector bodies that can be combined with each other or used individually. The connector bodies are used to position square steel. The connector body includes a base plate, a first baffle plate is vertically provided on one side of the base plate, and a second baffle plate is vertically provided on the other side of the base plate. The second baffle plate is detachably provided. The base plate, the first baffle plate, and the second baffle plate together form a square groove for engaging with the square steel. A load-bearing plate is provided on the side wall of the first baffle plate away from the base plate. The load-bearing plate is detachably provided on the side of the first baffle plate facing the square groove.

[0012] The connector body is equipped with transmission mechanisms respectively located at the base plate and the first retaining plate. The power input point of the transmission mechanism is located at the center of the base plate, and the power output point of the transmission mechanism is located at the first retaining plate. The square steel acts on the power input point, and the transmission mechanism is used to transmit the power from the power input point to the power output point. The power output point acts on the load-bearing plate to make the load-bearing plate apply pressure to the square steel.

[0013] The skeleton connector provided by the present invention can position a single square steel or multiple square steels in actual use, so that the square steels remain stable at the predetermined position, thereby making it easier for installation workers to weld and thus realize the construction of the prefabricated cabin skeleton.

[0014] Specifically, when assembling prefabricated cabins, installers need to pre-build the cabin frame, which involves arranging and welding square steel bars one by one to form the frame. During welding, due to the large size of the prefabricated cabin, adjacent square steel bars need to be aligned. Existing methods typically require at least two workers: one to support and align the adjacent steel bars, and the other to weld. This not only increases labor costs but also makes it difficult to ensure relative stability between adjacent steel bars. If the welding between adjacent steel bars does not meet construction requirements after completion, rework and re-welding are necessary, thus extending the overall construction cycle of the prefabricated cabin. The frame connector provided by this invention, when used to position a single square steel bar, requires the installer to first… Multiple frame connectors are sequentially fixed at the pre-installation position of the square steel. Then, the square steel is inserted into the square slot. During the insertion process, the square steel can compress the load-bearing plate, allowing the surface of the load-bearing plate to fit between the square steel and the first side plate. Therefore, the load-bearing plate can pre-position the square steel within the square slot. At this time, the installer can also make fine adjustments to the length of the square steel. When the square steel is fully inserted into the square slot, the corresponding part of the side wall of the square steel can act on the power input point of the transmission mechanism. Under the power transmission of the transmission mechanism, the power output point of the transmission mechanism acts on the load-bearing plate. At this time, the load-bearing plate has pressure on one side of the square steel, thus better achieving the positioning of the square steel in the square slot, which facilitates the installation workers to weld the square steel.

[0015] In this invention, a travel hole is provided through the center of the base plate, a first transmission groove is provided on the inner wall of the travel hole facing the first baffle plate, a second transmission groove is provided on the first baffle plate at the end of the first transmission groove, and the second transmission groove is open on one side and connected to the square slot.

[0016] The transmission mechanism includes a first transmission block movably disposed in a first transmission groove and a second transmission block movably disposed in a second transmission groove;

[0017] The first transmission block has a first transmission surface at the end of the first transmission block located at the stroke hole, and a second transmission surface at the end of the first transmission block located at the first side plate; the second transmission block has a third transmission surface at the end near the first transmission block for interacting with the second transmission surface, and a fourth transmission surface at the other end of the second transmission block;

[0018] The first baffle plate is provided with a mating groove at the opening on one side of the second transmission groove, and the corresponding part of the side wall of the load-bearing plate is provided with a mating block located at the mating groove. The mating block has a first mating surface that mates with the fourth transmission surface.

[0019] A stroke block is provided at the stroke hole. The upper end face of the stroke block is used to mate with the square steel, and the lower end face of the stroke block forms a second mating surface, which is used to mate with the first transmission surface.

[0020] In this invention, when the square steel is fully inserted into the square slot, the corresponding part of the side wall of the square steel can press the travel block, so that the travel block can move into the travel hole, so that the second mating surface of the travel block engages with the first transmission surface of the first transmission block, so that the first transmission block moves towards the second transmission block in the first transmission groove. Then, the second transmission surface of the first transmission block engages with the third transmission surface of the second transmission block, so that the second transmission block moves in the second transmission groove, and the fourth transmission surface of the second transmission block engages with the first mating surface of the support plate, so that the support plate has pressure towards the square steel, thereby better realizing the positioning of the square steel in the square slot, thus facilitating the installation workers to weld the square steel.

[0021] In this invention, a third transmission groove is provided at the point of interference between the base plate and the first side plate, and the corresponding end of the first transmission groove is connected to the middle of the third transmission groove; the first side plate is provided with two fourth transmission grooves on both sides of the second transmission groove, and one side of the fourth transmission groove is open and connected to the square slot; a third transmission block is movably arranged in the third transmission groove on both sides of the first transmission groove, and a fifth transmission surface is formed on both sides of the first transmission block on the second transmission surface. A sixth transmission surface is formed on the end of the third transmission block near the first transmission block for cooperating with the fifth transmission surface, and a seventh transmission surface is formed on the end of the third transmission block away from the first transmission block; a fourth transmission block is movably arranged in each of the two fourth transmission grooves, and an eighth transmission surface is formed on the end of the fourth transmission block near the third transmission block for cooperating with the seventh transmission surface, and a ninth transmission surface is formed on the end of the fourth transmission block away from the third transmission block, which is used to cooperate with the first mating surface.

[0022] In this invention, when the first transmission block moves toward the second transmission block within the first transmission groove, the second transmission surface of the first transmission block engages with the third transmission surface of the second transmission block, while the fifth transmission surface of the first transmission block engages with the sixth transmission surface of the third transmission block, causing the third transmission block to move within the third transmission groove. This, in turn, causes the seventh transmission surface of the third transmission block to engage with the eighth transmission surface of the fourth transmission block, enabling the fourth transmission block to move synchronously with the second transmission block. The ninth transmission surface of the fourth transmission block engages with the first mating surface of the support plate, giving the support plate pressure toward the square steel side. Therefore, the square steel is better positioned in the square slot, facilitating welding of the square steel by installation workers.

[0023] In this invention, the side wall of the first transmission block is provided with a first slot for the corresponding end of the second transmission block to be engaged.

[0024] In this invention, the first transmission block moves within the first transmission groove under the action of the stroke block, so that the second transmission surface of the first transmission block engages with the third transmission surface of the second transmission block. After the second transmission block moves within the second transmission groove, the end of the second transmission block located at the third transmission surface can be engaged into the first slot of the first transmission block. On one hand, the first transmission block ensures that the fourth transmission surface of the second transmission block engages with the first mating surface of the load-bearing plate. On the other hand, the second transmission block reacts to the first transmission block, so that the position of the first transmission block within the first transmission groove remains fixed, which is more convenient.

[0025] In this invention, the side wall of the third transmission block is provided with a second slot for the corresponding end of the fourth transmission block to be engaged.

[0026] In this invention, the third transmission block moves within the third transmission groove under the action of the first transmission block, so that the seventh transmission surface of the third transmission block engages with the eighth transmission surface of the fourth transmission block. After the fourth transmission block moves within the fourth transmission groove, the end of the fourth transmission block located at the eighth transmission surface can be engaged into the second slot of the third transmission block. On one hand, the third transmission block ensures that the ninth transmission surface of the fourth transmission block remains engaged with the first mating surface of the load-bearing plate. On the other hand, the fourth transmission block reacts to the third transmission block, keeping the position of the third transmission block within the third transmission groove fixed, which is more convenient.

[0027] In this invention, the base plate has four mounting holes on its surface, and the lines connecting the four mounting holes form a rectangle.

[0028] The above-described structure allows the mounting holes to better accommodate the frame connector at the ground foundation, and also better facilitates the vertical assembly of the two connector bodies.

[0029] In this invention, a connecting groove is provided on one side of the base plate near the second side plate; the connecting groove is used to cooperate with a connecting plate to combine the multiple connecting body bodies together.

[0030] The above-described structure enables the connecting groove to better achieve horizontal assembly between the two connecting bodies, and better enable the second baffle plate to be detachably installed at the connecting groove.

[0031] In this invention, the first side plate has a mounting groove on the side away from the base plate, and the corresponding side of the load-bearing plate is bent to form a mounting strip for engaging with the mounting groove; the surface of the load-bearing plate and the surface of the first side plate form an angle.

[0032] By using the mounting slot and mounting strip in this invention, the installation of the load-bearing plate at the first baffle plate is preferably achieved. The frame connector used in this invention is made of steel. The advantage of setting an angle between the load-bearing plate and the first baffle plate is that, during the process of the square steel being inserted into the square slot of the frame connector, the load-bearing plate can be deformed by the square steel. At this time, the load-bearing plate has a certain elasticity, thus enabling the pre-positioning of the square steel.

[0033] In this invention, the side of the load-bearing plate facing the square slot is a rough surface.

[0034] The above structure means that the sidewalls of the square steel are usually not smooth, so the rough surface of the load-bearing plate can better match the sidewalls of the square steel, thereby preventing the square steel from sliding in the square slot.

[0035] The present invention also provides a modular substation prefabricated module, which includes a module body, the module body including a frame component, the frame component being mainly constructed of multiple square steels; a single square steel or adjacent square steels are connected by any of the above-mentioned frame connectors.

Detailed Implementation

[0041] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0042] Example 1

[0043] Seen in Figure 1 This embodiment provides a modular prefabricated substation module (i.e., a module-type substation), which includes a module 00 (i.e., the main body of the substation / prefabricated module); the module 00 has a bottom plate component 01 and side plate components 02 ( Figure 1 The side plate components at both ends (not shown) and the top plate component 03, the bottom plate component 01, the side plate component 02 and the top plate component 03 all have a frame component made of steel profiles and a wall panel assembly made of sheet metal.

[0044] Seen in Figure 1 The frame components include a bottom frame 10, side frame 11, and top frame 12, all of which can be assembled from materials such as channel steel or square steel. The wall panel assembly includes individual wall panels 13, which can be cut or pressed from existing sheet or composite panels.

[0045] In this embodiment, the cabin 00 can be mounted on the ground foundation via the anchor connector 30, thus enabling convenient on-site installation of the cabin 00.

[0046] In this embodiment, a switch cabinet 20 is provided above the bottom frame 10, and the bottom frame 10 is fixedly or detachably provided with a switch cabinet relocation device at any switch cabinet 20, so that the relocation and subsequent maintenance of the switch cabinet can be better realized within the cabin 00.

[0047] Seen in Figure 2 In this embodiment, to achieve online monitoring of equipment inside the cabin, such as switch cabinets, an in-cabin monitoring system is also installed inside the cabin 00. The system body has a monitoring unit, which is used to acquire real-time images of the equipment inside the cabin 00. Furthermore, the monitoring unit is moved within the cabin 00 by a walking unit and its shooting angle is changed by a rotating unit, thus enabling more comprehensive and effective image capture of the environment inside the cabin 00. The walking unit is controlled by a first control unit, and the rotating unit is controlled by a second control unit. The control units at the first and second control units... All control commands can be issued by a single processing unit. This processing unit can communicate with a remote location via a wireless communication module, thus enabling better remote control of the monitoring unit, including image acquisition, acquisition position, and acquisition angle. Simultaneously, the processing unit can also process the image data acquired by the monitoring unit, thus enabling better transmission of the acquired image data to a remote location. Furthermore, the monitoring unit can be equipped with a battery unit, which can be managed by a battery management unit, and the battery management unit can charge the battery unit via a charging unit.

[0048] In this embodiment, the monitoring unit can include a camera component, thus enabling better acquisition of image data.

[0049] In this embodiment, the walking unit may include a track mounting frame 40, which can be arranged along the arrangement direction of the switch cabinets 20, thus enabling the monitoring unit to better cover all switch cabinets 20 with its shooting range. The track mounting frame 40 can be connected via a track connector (…). Figure 1 (Not shown) Installed at top plate component 03.

[0050] In this embodiment, the rotating unit may include a gimbal assembly, thus enabling better adjustment of the shooting angle of the monitoring unit.

[0051] In this embodiment, components such as the first control unit, the second control unit, the processing unit, the battery unit, the battery management unit, and the charging unit can be implemented based on existing devices or programs, and will not be described in detail in this embodiment.

[0052] Example 2

[0053] This embodiment provides a universal skeleton connector, which can better realize the construction of the skeleton components in Embodiment 1. It can be applied to the parallel, orthogonal and horizontal positioning or connection between adjacent square steels, as well as the positioning or connection between a single square steel and such as channel steel or wall panel.

[0054] Seen in Figure 3-17 The skeleton connector of this embodiment includes multiple connector bodies 1000 that can be combined or used individually. The connector bodies 1000 are used to position the square steel. The connector body 1000 includes a base plate 1100. A first baffle plate 1200 is vertically provided on one side of the base plate 1100, and a second baffle plate 1300 is vertically provided on the other side of the base plate 1100. The second baffle plate 1300 is detachably provided. The base plate 1100, the first baffle plate 1200, and the second baffle plate 1300 together form a square slot 1500, which is used to cooperate with the square steel. A load-bearing plate 1400 is provided on the side wall of the first baffle plate 1200 away from the base plate 1100. The load-bearing plate 1400 is detachably provided on the side of the first baffle plate 1200 facing the square slot 1500.

[0055] A transmission mechanism is provided at the connector body 1000 between the base plate 1100 and the first baffle plate 1200. The power input point of the transmission mechanism is located at the center of the base plate 1100, and the power output point of the transmission mechanism is located at the first baffle plate 1200. The square steel acts on the power input point, and the transmission mechanism is used to transmit the power from the power input point to the power output point. The power output point acts on the load-bearing plate 1400 so that the load-bearing plate 1400 applies pressure to the square steel.

[0056] The base plate 1100 and the first side plate 1200 can be integrally formed.

[0057] The skeleton connector provided in this embodiment can better achieve the positioning or connection of a single square steel or multiple square steels in actual use, thereby better realizing the construction of the prefabricated cabin skeleton components.

[0058] Specifically, the skeleton connector provided in this embodiment, in actual use:

[0059] When it is necessary to position or connect individual square steel bars, it can be achieved by combining the base plate 1100, the second edge plate 1300, and the load-bearing plate 1400, etc. (i.e.) Figure 3In the state of the square steel, the square steel can be completely inserted into the square slot 1500. During the process of the square steel being inserted into the square slot 1500, the surface of the support plate 1400 can be attached between the square steel and the first side plate 1200. When the square steel is completely inserted into the square slot 1500, the corresponding part of the side wall of the square steel can provide power to the power input point of the transmission mechanism (this power is provided by the squeezing force of the square steel being inserted). The power output point of the transmission mechanism acts on the support plate 1400. At this time, the support plate 1400 has a squeezing tendency towards the square steel, thereby better realizing the positioning or connection of the square steel in the square slot 1500.

[0060] When it is necessary to position or connect two parallel square steel sections, the two connecting body 1000s with the second side plate 1300 removed can be connected. Figure 14 (in the state of the middle), and then the corresponding two square steels are inserted into the corresponding square slot 1500 to achieve the desired result;

[0061] When it is necessary to position or connect two parallel or orthogonal square steel pieces, the two connector bodies 1000 can be connected (respectively). Figure 16 and Figure 17 (In the state of the middle), then insert the corresponding two square steels into the corresponding square slots 1500 respectively, and it can be realized.

[0062] Through the above, the positioning or connection of square steel under different working conditions can be better achieved. It can be understood that the corresponding square steel can be directly connected through the connector body 1000; at some key connection nodes, the square steel can be positioned first through the connector body 1000 (i.e., pre-connection), and then secondary reinforcement can be carried out through welding or other methods. This can effectively eliminate welding stress.

[0063] Furthermore, it is understood that the second baffle plate 1300 is detachable, meaning that the second baffle plate 1300 and the base plate 1100 are not integrally constructed. In practical use, the connection between the second baffle plate 1300 and the base plate 1100 can be achieved through methods such as welding, and different... Figure 14 Connection between the two base boards 1100 in the middle state.

[0064] Furthermore, when positioning or connecting individual square steel bars, the base plate 1100 can be connected to materials such as channel steel or wall panels by means such as welding; when multiple connector bodies 1000 are used in combination, the base plates 1100 can also be connected to each other by means such as welding.

[0065] In one specific embodiment, the base plate 1100 has four mounting holes 1110 arranged in a rectangular array on its surface. The mounting holes 1110 are located on the outer side of the base plate 1100 and can form connecting grooves 1130. The connecting grooves 1130 can also form openings on the sidewalls of the base plate 1100. The opening directions of the two connecting grooves 1130 near the first baffle plate 1200 of the four mounting holes 1110 are parallel to the extending direction of the square slot 1500. The opening directions of the two connecting grooves 1130 near the second baffle plate 1200 of the four mounting holes 1110 are parallel to the extending direction of the square slot 1500. The opening direction of the two connecting slots 1130 of the side plate 1300 is perpendicular to the extension direction of the square slot 1500. In addition, the second side plate 1300 is also provided with a lug for cooperating with the corresponding connecting slot 1130. Therefore, the second side plate 1300 and the base plate 1100 can be quickly assembled by means of fasteners such as screws. At the same time, the base plate 1100 can be quickly spliced ​​in two orthogonal directions by means of connecting plate assemblies, thus having better applicability.

[0066] In this embodiment, a travel hole 1120 is provided through the center of the base plate 1100. The inner wall of the travel hole 1120 is provided with a first transmission groove 1710 facing the first baffle plate 1200. The first baffle plate 1200 is provided with a second transmission groove 1720 at the end of the first transmission groove 1710. The second transmission groove 1720 is open on one side and connected to the square slot 1500.

[0067] The transmission mechanism includes a first transmission block 1810 movably disposed in the first transmission groove 1710 and a second transmission block 1820 movably disposed in the second transmission groove 1720;

[0068] The first transmission block 1810 has a first transmission surface 1811 at the end of the first transmission block 1810 located at the stroke hole 1120, and a second transmission surface 1812 at the end of the first transmission block 1810 located at the first baffle plate 1200; the second transmission block 1820 has a third transmission surface 1821 at the end near the first transmission block 1810 for interaction with the second transmission surface 1812, and a fourth transmission surface 1822 at the other end of the second transmission block 1820;

[0069] The first baffle plate 1200 is provided with a mating groove 1210 at the opening on one side of the second transmission groove 1720. The corresponding part of the side wall of the load-bearing plate 1400 is provided with a mating block 1410 located at the mating groove 1210. The mating block 1410 has a first mating surface 1411 that mates with the fourth transmission surface 1822.

[0070] A stroke block 1600 is provided at the stroke hole 1120. The upper end face of the stroke block 1600 is used to mate with the square steel, and the lower end face of the stroke block 1600 forms a second mating surface 1610, which is used to mate with the first transmission surface 1811.

[0071] In this embodiment, when the square steel is fully inserted into the square slot 1500, the corresponding part of the side wall of the square steel can press the stroke block 1600, so that the stroke block 1600 can move into the stroke hole 1120, so that the second mating surface 1610 of the stroke block 1600 is mated with the first transmission surface 1811 of the first transmission block 1810, so that the first transmission block 1810 moves towards the second transmission block 1820 in the first transmission groove 1710. Then, the second transmission surface 1812 of the first transmission block 1810 is mated with the third transmission surface 1821 of the second transmission block 1820, so that the second transmission block 1820 moves in the second transmission groove 1720, and the fourth transmission surface 1822 of the second transmission block 1820 is mated with the first mating surface 1411 of the support plate 1400, so that the support plate 1400 has pressure towards the square steel, thereby better realizing the positioning of the square steel in the square slot 1500, thus facilitating the installation workers to weld the square steel.

[0072] In this embodiment, a third transmission groove 1730 is provided at the point of interference between the base plate 1100 and the first baffle plate 1200, and the corresponding end of the first transmission groove 1710 is connected to the middle of the third transmission groove 1730; the first baffle plate 1200 is provided with two fourth transmission grooves 1740 on both sides of the second transmission groove 1720, and one side of the fourth transmission groove 1740 is open and connected to the square slot 1500; a third transmission block 1830 is movably arranged in the third transmission groove 1730 on both sides of the first transmission groove 1710, and a fifth transmission surface 1813 is formed on both sides of the second transmission surface 1812 of the first transmission block 1810. The end of the transmission block 1830 near the first transmission block 1810 has a sixth transmission surface 1831 for engaging with the fifth transmission surface 1813, and the end of the third transmission block 1830 away from the first transmission block 1810 has a seventh transmission surface 1832. A fourth transmission block 1840 is movably disposed within each of the two fourth transmission slots 1740. The end of the fourth transmission block 1840 near the third transmission block 1830 has an eighth transmission surface 1841 for engaging with the seventh transmission surface 1832, and the end of the fourth transmission block 1840 away from the third transmission block has a ninth transmission surface 1842, which engages with the first mating surface 1411.

[0073] In this embodiment, when the first transmission block 1810 moves towards the second transmission block 1820 within the first transmission groove 1710, the second transmission surface 1812 of the first transmission block 1810 engages with the third transmission surface 1821 of the second transmission block 1820, while the fifth transmission surface 1813 of the first transmission block 1810 engages with the sixth transmission surface 1831 of the third transmission block 1830. This causes the third transmission block 1830 to move within the third transmission groove 1730, thereby enabling the third transmission block... The seventh transmission surface 1832 of the fourth transmission block 1840 cooperates with the eighth transmission surface 1841 of the fourth transmission block 1840, so that the fourth transmission block 1840 can move synchronously with the second transmission block 1820. The ninth transmission surface 1842 of the fourth transmission block 1840 cooperates with the first mating surface 1411 of the support plate 1400, so that the support plate 1400 has pressure towards the square steel side, thus better realizing the positioning of the square steel in the square slot 1500, thus facilitating the installation workers to weld the square steel.

[0074] The purpose of setting the fourth transmission block 1840 is, on the one hand, to make the load on the load-bearing plate 1400 more balanced, and on the other hand, to reduce the pressure on the second transmission block 1820, so as to ensure the reliable use of the frame connector.

[0075] In this embodiment, the side wall of the first transmission block 1810 is provided with a first slot for the corresponding end of the second transmission block 1820 to be inserted.

[0076] In this embodiment, the first transmission block 1810 moves within the first transmission groove 1710 under the action of the stroke block 1600, so that the second transmission surface 1812 of the first transmission block 1810 engages with the third transmission surface 1821 of the second transmission block 1820. After the second transmission block 1820 moves within the second transmission groove 1720, the end of the second transmission block 1820 located at the third transmission surface 1821 can be engaged into the first slot of the first transmission block 1810. On the one hand, the first transmission block 1810 ensures that the fourth transmission surface 1822 of the second transmission block 1820 engages with the first mating surface 1411 of the support plate 1400. On the other hand, the second transmission block 1820 reacts to the first transmission block 1810, so that the position of the first transmission block 1810 within the first transmission groove 1710 remains fixed, which is more convenient.

[0077] In this embodiment, the side wall of the third transmission block 1830 is provided with a second slot for the corresponding end of the fourth transmission block 1840 to be engaged.

[0078] In this embodiment, the third transmission block 1830 moves within the third transmission groove 1730 under the action of the first transmission block 1810, so that the seventh transmission surface 1832 of the third transmission block 1830 engages with the eighth transmission surface 1841 of the fourth transmission block 1840. After the fourth transmission block 1840 moves within the fourth transmission groove 1740, the end of the fourth transmission block 1840 located at the eighth transmission surface 1841 can be engaged into the second slot of the third transmission block 1830. On the one hand, the third transmission block 1830 ensures that the ninth transmission surface 1842 of the fourth transmission block 1840 remains engaged with the first mating surface 1411 of the support plate 1400. On the other hand, the fourth transmission block 1840 reacts to the third transmission block 1830, so that the position of the third transmission block 1830 within the third transmission groove 1730 remains fixed, which is more convenient.

[0079] In this embodiment, the first side plate 1200 is provided with a mounting slot 1220 on the side away from the base plate 1100, and the load-bearing plate 1400 is bent on the corresponding side to form a mounting strip 1420 for being inserted into the mounting slot 1220; the surface of the load-bearing plate 1400 forms an angle with the surface of the first side plate 1200.

[0080] With the installation slot 1220 and the installation strip 1420 in this embodiment, the installation of the load-bearing plate 1400 at the first baffle plate 1200 is better achieved. In this embodiment, the material of the skeleton connector is steel. The advantage of setting an angle between the load-bearing plate 1400 and the first baffle plate 1200 is that the load-bearing plate 1400 can be squeezed and deformed by the square steel during the process of the square steel being inserted into the square slot 1500 of the skeleton connector. At this time, the load-bearing plate 1400 has a certain elastic force, so the square steel can be pre-positioned.

[0081] In this embodiment, the side of the load-bearing plate 1400 facing the square slot 1500 is a rough surface.

[0082] The above structure means that the sidewalls of the square steel are usually not smooth, so the rough surface of the load-bearing plate 1400 can better match the sidewalls of the square steel, thereby preventing the square steel from sliding in the square slot 1500.

[0083] Example 3

[0084] This embodiment provides a universal mounting component, which can be better used as the foot connector in Embodiment 1, thus enabling better installation between the cabin and the ground foundation.

[0085] like Figure 18-24 As shown, the universal mounting component of this embodiment includes a mounting component body 2000, and the mounting component body 2000 has:

[0086] Mounting assembly 2100 includes a rotatable mounting plate 2110, a groove 2300 provided at the mounting plate 2110, the groove 2300 being arranged radially along the mounting plate 2110; a mounting part 2120 is slidably provided at the groove 2300, the mounting part 2120 having a threaded section 2122.

[0087] Base assembly 2200, including base 2210, base 2210 having mounting slot 2400 for mounting mounting plate 2110; and

[0088] An anti-pull mechanism is provided at the mounting component 2100 or the base component 2200. The anti-pull mechanism is used to position the mounting plate 2110 within the mounting groove 2400.

[0089] In actual use, the universal mounting component provided in this embodiment allows the mounting part 2120 to be adjusted in position on the surface area of ​​the mounting plate 2110 to create an installation offset. This allows the installer to better adjust the mounting part 2120 when installing the target object (such as a prefabricated cabin) so that the target object can be installed at the predetermined installation position, thereby avoiding the inability to install the target object due to construction errors.

[0090] In this embodiment, the base assembly 2200 can be pre-embedded in the ground foundation when the cabin is installed.

[0091] Specifically, the installer first installs several universal mounting parts at the corresponding installation points according to the construction requirements. That is, the installer installs the base assembly 2200 of the universal mounting part at the installation point, and then installs the target object at the mounting assembly 2100 of the universal mounting part. The target object has through holes for mating with the mounting part 2120. Therefore, during the installation of the target object, the installer needs to adjust the position of the mounting part 2120 on the surface area of ​​the mounting plate 2110 so that the mounting part 2120 can accurately mate with the through holes of the target object. Then, the nut is threaded onto the mounting part 2120 so that the target object is fixed in the predetermined installation position by the interaction between the mounting part 2120 and the nut, which is more convenient.

[0092] It is worth mentioning that the existing method generally involves directly fixing the threaded post at the corresponding installation point and then installing the target object at the threaded post. However, this method requires the target object to be precisely aligned with the threaded post. If the target object is a prefabricated cabin, and prefabricated cabins generally require a large number of threaded posts, even if the through-hole opening position of the prefabricated cabin is correct and the threaded post installation point is correct, the installer still needs to align it precisely. If the threaded post is misaligned during installation or the through-hole opening position of the prefabricated cabin is misaligned, the through-hole of the prefabricated cabin cannot be matched with the threaded post, resulting in the prefabricated cabin not being able to be installed at the predetermined installation position. The universal mounting component provided in this embodiment can overcome the above two errors. That is, by adjusting the position of the mounting part 2120 on the surface area of ​​the mounting plate 2110, it can better ensure that the through-hole of the prefabricated cabin can be aligned with the mounting part 2120 of the universal mounting component, thereby ensuring the installation of the prefabricated cabin at the predetermined installation position.

[0093] The universal mounting components provided in this embodiment are well suited for construction scenarios where a large number of universal mounting components are required and the construction requirements are high.

[0094] The mounting plate 2110 can rotate along the axial direction of the mounting groove 2400, and the mounting part 2120 can slide radially within the sliding groove 2300 of the mounting plate 2110. Therefore, the position of the mounting part 2120 on the surface area of ​​the mounting plate 2110 can be adjusted more effectively, thereby enabling the mounting part 2120 to accurately match the through hole of the target object when the installer is installing the target object, thus avoiding the inability to install the target object due to construction errors.

[0095] Among them, the anti-pull mechanism can better stabilize the mounting body 2000, that is, the mounting plate 2110 of the mounting component 2100 and the mounting groove 2400 of the base component 2200 are still engaged under the action of external force, which is more reliable.

[0096] In this embodiment, the construction error refers to the deviation of the threaded column when it is installed at the installation point or the deviation of the through hole opening position of the prefabricated compartment.

[0097] In this embodiment, the installation offset refers to the fact that when the threaded post is installed at the installation point and the through hole of the prefabricated compartment is misaligned, the installation part 2120 can adjust its position on the surface area of ​​the installation plate 2110 to achieve a fit with the through hole of the target object.

[0098] In this embodiment, the mounting part 2120 includes a slider 2121 located in the slide groove 2300, and a threaded section 2122 fixed to one side of the slider 2121; the slide groove 2300 has positioning rails 2310 formed on both sides along the length direction, and the slider 2121 has positioning grooves 2123 that cooperate with the positioning rails 2310 on both sides respectively.

[0099] In this embodiment, the positioning rail 2310 and the positioning groove 2123 cooperate to make the slider 2121 more stable when sliding in the groove 2300. After the through hole at the target object cooperates with the threaded section 2122, the slider 2121 can make the inner wall of the positioning groove 2123 abut against the outer wall of the positioning rail 2310 under the action of the nut, thereby fixing the slider 2121 at the groove 2300.

[0100] In this embodiment, the anti-pull mechanism is located at the base assembly 2200; the base 2210 has a shaft cavity 2500 along the axial direction, one end of the shaft cavity 2500 is opened at the bottom wall of the mounting groove 2400, and the mounting plate 2110 has a mounting post 2600 extending into the shaft cavity 2500 on the corresponding side wall; the base 2210 has a plurality of first movable grooves 2700 evenly spaced along the circumference of the shaft cavity 2500, the extension direction of the first movable grooves 2700 is parallel to the axial direction of the shaft cavity 2500, and the shaft cavity 2500 has a plurality of second movable grooves 2800 radially arranged along the base 2210, the second movable grooves 2800 connecting the first movable grooves 2700 and the shaft cavity 2500. 00, the second movable groove 2800 is located near the bottom wall of the shaft cavity 2500; the anti-pull mechanism includes a first movable part movably disposed in the first movable groove 2700 and a second movable part movably disposed in the second movable groove 2800, and an annular groove 2610 is provided at the corresponding wall of the mounting post 2600; when the mounting plate 2110 is completely placed in the mounting groove 2400, the mounting plate 2110 presses the first movable part to move in the first movable groove 2700, the first movable part presses the second movable part to move in the second movable groove 2800, and the corresponding end of the second movable part under the pressing action of the first movable part is engaged in the annular groove 2610.

[0101] With the above structure, when installing a target object such as a prefabricated cabin, the installer needs to drill countersunk holes at the predetermined installation position of the prefabricated cabin according to the actual number of the required universal mounting parts, and install the base assembly 2200 at the countersunk holes, so that the mounting assembly 2100 is exposed above the base assembly 2200. When the installer moves the prefabricated cabin to the predetermined installation position by means of transportation such as a crane, the position of the mounting part 2120 on the surface area of ​​the mounting plate 2110 is adjusted by several workers working together, so that the threaded section 2122 of any mounting part 2120 corresponds one-to-one with the through hole of the prefabricated cabin. Then, when the installer installs the prefabricated cabin at the predetermined installation position, he / she fixes the prefabricated cabin at the predetermined installation position by tightening the nut, which is more convenient.

[0102] During the installation of the prefabricated cabin, the prefabricated cabin is generally heavy. Therefore, the mounting plate 2110 can be squeezed into the mounting groove 2400 under the pressure of the prefabricated cabin. At the same time, the mounting plate 2110 can act on the first movable part, so that the first movable part moves in the first movable groove 2700 and the corresponding end of the first movable part acts on the second movable part, thereby causing the second movable part to move in the second movable groove 2800 and the corresponding end of the second movable part acts on the annular groove 2610 of the mounting column 2600. Therefore, a stable connection between the mounting component 2100 and the base component 2200 is better installed.

[0103] It is worth mentioning that in windy weather, the wind resistance of the prefabricated cabin may affect the centrifugal force of the prefabricated cabin. Therefore, an anti-pull mechanism is set to ensure a stable connection between the installation component 2100 and the base component 2200, thereby improving the installation stability of the prefabricated cabin at the predetermined installation position.

[0104] In this embodiment, the first movable part includes a pressing head 2710, a first spring 2720 and a first pin 2730 arranged sequentially along the first movable groove 2700. The first pin 2730 has a first wedge surface 2731. The second movable part includes a second pin 2810. One end of the second pin 2810 is formed with a second wedge surface 2812 for engaging with the first wedge surface 2731. The other end of the second pin 2810 is formed with a locking head 2811, which is tightly engaged in the annular locking groove 2610.

[0105] With the above structure, when the installer is installing the target object such as the prefabricated cabin, the installation plate 2110 can be squeezed into the installation groove 2400 under the pressure of the prefabricated cabin. This allows the bottom wall of the installation plate 2110 to press the extrusion head 2710 and cause the extrusion head 2710 to drive the first pin block 2730 to move towards the bottom wall of the first movable groove 2700. The first wedge surface 2731 of the first pin block 2730 can act on the second pin block 2810, causing the second pin block 2810 to move within the second movable groove 2800. The locking head 2811 of the second pin block 2810 can be squeezed into the annular locking groove 2610, thereby achieving a stable connection between the installation component 2100 and the base component 2200.

[0106] The advantage of the close fit between the clasp 2811 and the annular groove 2610 is that the outer wall of the clasp 2811 can fit more completely against the annular inner wall. Therefore, it can not only achieve axial locking of the mounting post 2600 at the shaft cavity 2500, but also further restrict the circumferential rotation of the mounting post 2600, which is more reliable.

[0107] The first spring 2720 can act as a buffer to prevent damage to the internal structure caused by the first wedge surface 2731 of the first pin block 2730 and the second wedge surface 2812 of the second pin block 2810 not engaging in time when the prefabricated cabin falls relatively quickly.

[0108] In this embodiment, a second spring 2510 is provided between the bottom wall of the shaft cavity 2500 and the mounting post 2600.

[0109] With the above structure, before the prefabricated compartment is installed at the predetermined installation position, the second spring 2510 can abut against the bottom wall of the mounting post 2600 and cause the mounting plate 2110 to partially extend out of the mounting groove 2400, thus enabling the prefabricated compartment to better cooperate with the mounting assembly 2100.

[0110] In this embodiment, the outer wall of the base 2210 is provided with a plurality of fixing slots 2211 evenly spaced along the circumference.

[0111] With the above structure, when installing a target object such as a prefabricated cabin, the installer needs to drill countersunk holes at the predetermined installation position of the prefabricated cabin according to the actual required number of the universal mounting parts, and install the base assembly 2200 at the countersunk hole.

[0112] The fixing slot 2211 allows the addition of a connecting medium, such as concrete, between itself and the inner wall of the counterbore, thus enabling the installation of the universal mounting component at a predetermined installation location (ground foundation).

[0113] Example 4

[0114] This embodiment also provides a universal mounting component, which can be better used as the track connector in Embodiment 1, thus enabling better installation between the track mounting frame and the top plate component.

[0115] like Figure 25-28 As shown, the difference between the general mounting component of this embodiment and that of Embodiment 3 is that: the anti-pull mechanism is located at the mounting assembly 2100; the diameter of the mounting groove 2400 gradually increases from the opening of the mounting groove 2400 toward the bottom wall of the mounting groove 2400; the mounting plate 2110 is provided with a plurality of third movable grooves 2900 evenly spaced along the circumference, and the third movable grooves 2900 are arranged radially along the mounting plate 2110; a third movable part is provided in the third movable groove 2900; the mounting plate 2110 is provided with a threaded hole communicating with the third movable groove 2900 on one side of the opening of the mounting groove 2400, and a bolt is threadedly connected to the threaded hole, the end of the bolt is used to abut against the third movable part, and the third movable part is used to abut against the inner wall of the mounting groove 2400.

[0116] With the above structure, when installing a target object such as a track mounting bracket, the installer needs to install the universal mounting bracket at the predetermined installation position of the track mounting bracket according to the actual required quantity of the universal mounting bracket.

[0117] Before installing the aforementioned universal mounting component at the predetermined installation position on the track mounting bracket, the installer needs to pre-tighten the bolts so that the bolts can abut against the third movable part. Under the action of the bolts, the third movable part can move within the third movable groove 2900 so that the corresponding end of the third movable part extends out of the third movable groove 2900 and engages with the inner wall of the mounting groove 2400. At this time, the mounting plate 2110 can be locked within the mounting groove 2400 and can rotate. Then, the required universal mounting component is installed at the predetermined installation position on the track mounting bracket, and finally the track mounting bracket is installed.

[0118] When installing the track mounting bracket, first adjust the position of the mounting part 2120 on the surface area of ​​the mounting plate 2110, and then align the through holes of the track mounting bracket with the corresponding mounting parts 2120 one by one, so that the track mounting bracket can be better installed at the predetermined installation position.

[0119] Finally, tighten the bolts to fix the third movable part in the third movable groove 2900;

[0120] In this embodiment, the predetermined installation position of the track mounting frame can be the top wall inside the prefabricated cabin.

[0121] In this embodiment, the third movable part includes a third pin 2910. The end of the third pin 2910 near the mounting groove 2400 has a third wedge surface 2911, and the end of the third pin 2910 away from the mounting groove 2400 has a wedge head. The wedge head has a fourth wedge surface 2912 and a pressure plate 2913 for engaging with the end of the bolt, respectively. The pressure plate 2913 is used to abut against the corresponding wall of the third movable groove 2900 under the action of the bolt. A third spring 2920 is sleeved inside the third movable groove 2900, and the third pin 2910 keeps the third wedge surface 2911 inside the third movable groove 2900 under the action of the third spring 2920.

[0122] With the above structure, before the universal mounting component is installed at the predetermined installation position of the track mounting bracket, the fourth wedge surface 2912 of the third pin block 2910, under the action of the bolt, allows the third wedge surface 2911 of the third pin block 2910 to abut against the inner wall of the mounting groove 2400, thereby enabling the mounting plate 2110 to be locked and rotated within the mounting groove 2400; when the track mounting bracket is installed, the bolt is tightened so that the end of the bolt abuts against the pressure plate 2913 of the third pin block 2910, thereby fixing the third pin block 2910 within the third movable groove 2900;

[0123] When the bolt releases the third pin 2910, the third spring 2920 tends to move the third pin 2910 toward the third movable groove 2900, thus making it easier to disassemble and assemble this universal mounting component.

[0124] In this embodiment, the outer wall of the base 2210 is provided with a plurality of mounting ears 2212 evenly spaced along the circumference.

[0125] With the installation ear 2212 configured in this embodiment, the installation of the universal mounting component at the predetermined installation position on the track mounting frame is preferably achieved.

[0126] Example 5

[0127] This embodiment provides an in-cabin monitoring device for mounting the in-cabin monitoring system in Embodiment 1. This embodiment also provides a specific implementation structure of the track mounting frame 40 in Embodiment 1.

[0128] like Figure 29-32 As shown, the in-cabin monitoring device of this embodiment includes a monitoring device body 4000, which includes a track mounting frame 40. The track mounting frame 40 is mounted on the top wall of the prefabricated cabin (i.e., the top plate component 03) via a mounting component (such as the universal mounting component in embodiment 4). The track mounting frame 40 has a mounting frame 4200 and a track frame 4100. A monitoring mechanism (i.e., the hardware structure of the monitoring unit) is provided at the track frame 4100. The monitoring mechanism is used to monitor the equipment inside the prefabricated cabin (i.e., image acquisition). A walking mechanism (i.e., the hardware structure of the walking unit) is provided at the track frame 4100 to reciprocate the monitoring mechanism along the length of the track frame 4100. A charging mechanism (i.e., the hardware structure of the charging unit) is provided at one end of the track frame 4100 along the length of the track frame. The charging mechanism is used to supply power to the battery unit at the monitoring mechanism.

[0129] In actual use, the main body 4000 of the monitoring device provided in this embodiment is first installed by the installation workers on the inner top wall of the prefabricated cabin according to the equipment to be monitored. Then the wiring is arranged. After the main body 4000 of the monitoring device is installed on the inner top wall of the prefabricated cabin, it can be powered on so that the monitoring mechanism can monitor the equipment inside the prefabricated cabin, such as whether there are any abnormalities on the surface of the monitoring equipment, during the reciprocating motion of the monitoring mechanism along the length of the track frame 4100 at the track mounting frame.

[0130] In this embodiment, the power source for the monitoring mechanism is a rechargeable battery (the battery unit includes a rechargeable battery). This not only reduces the arrangement of lines but also avoids the risk of the lines getting tangled during the movement of the monitoring mechanism. Therefore, the charging mechanism in this embodiment can provide power to the monitoring mechanism when its power is insufficient, thus ensuring the reliable operation of the monitoring mechanism.

[0131] In this embodiment, the track frame 4100 has bearing seats 4600 at both ends in the length direction; the traveling mechanism includes a lead screw 4510 disposed between the two bearing seats 4600 and a traveling plate 4800 cooperating with the lead screw 4510, and a monitoring mechanism is installed below the traveling plate 4800; a first drive motor 4520 for driving the lead screw 4510 to rotate is provided at one of the bearing seats 4600.

[0132] With the above structure, the first drive motor 4520 drives the lead screw to rotate, thus better realizing that the walking plate 4800 drives the monitoring mechanism to reciprocate along the length of the track frame 4100, thereby better realizing the monitoring of the equipment inside the prefabricated cabin.

[0133] In this embodiment, side plates 4400 are provided on both sides of the track frame 4100 along its length. The track frame 4100 and the corresponding walls of the two side plates 4400 together form a traveling groove 4410, and the traveling plate 4800 slides within the traveling groove 4410. Therefore, the stability of the traveling plate 4800 sliding within the traveling groove 4410 is better achieved.

[0134] In this embodiment, the monitoring mechanism includes a chassis 4910 installed below the walking plate 4800. A control cavity 4911 is formed in the chassis 4910. A monitor 4950 (which is essentially a camera) is located below the control cavity 4911. The monitor 4950 is used to monitor the equipment inside the prefabricated cabin. A rotating mechanism (a specific hardware structure of a rotating unit) is provided inside the control cavity 4911. The rotating mechanism is used to control the rotation of the monitor 4950. A controller 4920 (which can be an integrated circuit board of units such as a first control unit, a second control unit, a processing unit, and a battery management unit) and a rechargeable battery are provided inside the control cavity 4911. The controller 4920 is used to interact with the monitor 4950. The rechargeable battery is used to supply power to the controller 4920.

[0135] With the above structure, the monitor 4950 can monitor the equipment inside the prefabricated cabin and acquire monitoring data during the reciprocating motion along the length of the track frame 4100. Then, the monitor 4950 can send the monitoring data to the controller 4920, and the controller 4920 processes the monitoring data, thus better realizing the monitoring of the equipment inside the prefabricated cabin.

[0136] The rotating mechanism enables the monitor 4950 to rotate within a certain arc angle, thus enabling the monitoring of more prefabricated cabin equipment, which is more convenient.

[0137] The rechargeable battery preferably supplies power to the controller 4920 to ensure the normal operation of the monitoring mechanism.

[0138] In this embodiment, the rotating mechanism includes a second drive motor 4930 disposed in the control cavity 4911. The output shaft of the second drive motor 4930 extends out of the control cavity 4911 and a rotating plate 4940 is mounted on the end of the output shaft. A monitor 4950 is mounted on the rotating plate 4940.

[0139] With the above structure, the second drive motor 4930 drives the rotating plate 4940, thus better enabling the monitor 4950 to rotate within a certain arc angle, thereby better enabling the monitor 4950 to monitor the equipment inside a large number of prefabricated cabins.

[0140] In this embodiment, the charging mechanism includes a charging chamber 4710, which is located on the side of the track frame 4100 that is farther from the first drive motor 4520 in the length direction. A first charging terminal 4730 is provided inside the charging chamber 4710, and a second charging terminal 4960 is provided at the chassis 4910. The first charging terminal 4730 is used to cooperate with the second charging terminal 4960.

[0141] In this embodiment, when the power of the monitoring mechanism is insufficient, the monitoring mechanism can enter the charging chamber 4710 under the drive of the walking plate 4800, and the second charging terminal 4960 at the chassis 4910 can be electrically connected to the first charging terminal 4730 in the charging chamber 4710, thereby better realizing the charging of the rechargeable battery and ensuring the reliable operation of the monitoring mechanism.

[0142] In this embodiment, ventilation holes 4720 are provided on the side walls of both the charging compartment 4710 and the chassis 4910.

[0143] With the above structure, since rechargeable batteries generally generate a lot of heat during the charging process, ventilation holes 4720 are provided to prevent the heat from accumulating at the charging compartment 4710 during the charging process.

[0144] In this embodiment, the track frame 4100 and the mounting frame 4200 are connected by a connecting plate 4300; the mounting frame 4200 has a first mating hole 4210 and a second mating hole 4220 at both ends in the length direction, and the connecting plate 4300 has a third mating hole 4230 at the middle in the length direction. The first mating hole 4210, the second mating hole 4220 and the third mating hole 4230 are all used to connect with the mounting component.

[0145] With the above-described structure, the mounting bracket 4200 can be installed on the inner top wall of the prefabricated cabin in a better manner.

[0146] In this embodiment, the mounting component is fixed to the top wall inside the prefabricated cabin, and the mounting component has a threaded section; the first mating hole 4210 and the second mating hole 4220 are both strip-shaped holes and are arranged perpendicular to each other; the third mating hole 4230 is a round hole, and the diameter of the round hole is larger than the diameter of the threaded section.

[0147] With the above structure, if the installation position of the mounting component on the inner top wall of the prefabricated cabin is deviated during installation, the third mating hole 4230 can allow the track mounting frame to be finely adjusted within a certain range. Furthermore, the first mating hole 4210 and the second mating hole 4220 are arranged perpendicular to each other, thus better ensuring the stability of the track mounting frame when it is installed on the inner top wall of the prefabricated cabin.

[0148] Example 6

[0149] This embodiment provides a switch cabinet relocation device, which can be better applied to Embodiment 1.

[0150] Seen in Figure 33 The switchgear relocation device in this embodiment includes a device body 310; the device body 310 has:

[0151] Rolling assembly 311 for rolling engagement with the bottom wall of the switch cabinet;

[0152] A lifting component 312 is used to enable the rolling component 311 to move up and down in the height direction;

[0153] Two bracket assemblies 313 for mounting the lifting assembly 312; and

[0154] Drive component 314 for implementing lifting and lowering control of lifting component 312.

[0155] The above structure allows the main body 310 to be positioned below the installation location of the switchgear. By driving the lifting component 312 through the drive component 314, the position of the rolling component 311 in the height direction can be adjusted. Therefore, during the initial installation of the switchgear, the main body 310 can be positioned below the installation location of each switchgear, keeping the rolling component 311 in an elevated state. This allows all the rolling components 311 to connect and form a rolling track, thus enabling better relocation of any switchgear within the cabin to meet the installation and merging requirements of the switchgear. It can be understood that after any switchgear is installed and assembled, the corresponding rolling component 311 can be lowered, thus enabling the switchgear to be stably installed between itself and the cabin. In addition, after all switchgear is installed, when any single switchgear needs to be inspected and debugged, the connection between the single switchgear and the adjacent switchgear and the cabin can be disconnected first. Then, by setting the device body 310 below the installation position of the switchgear, the relocation of any switchgear from the installation position to the inspection and debugging position can be achieved more effectively.

[0156] It can be understood that the base of the cabin is a skeleton structure, and each switch cabinet is directly placed on the skeleton. Therefore, there is enough space under the installation position of each switch cabinet to accommodate the placement of the main body 310.

[0157] Seen in Figure 34 When the rolling component 311 is in the raised state, the rolling component 311 can protrude from the plane of the switch cabinet, thus providing better rolling displacement function.

[0158] Seen in Figure 35 When the rolling assembly 311 is in the descending state, the rolling assembly 311 can retract into the plane of the switch cabinet, thus better ensuring the stable assembly between the switch cabinet and the cabin.

[0159] Seen in Figure 36 The rolling assembly 311 includes a rolling bracket 341, the upper surface of which is flat and forms a ball bearing mounting surface 342. Multiple ball bearing mounting grooves 343 are spaced apart along the extending direction of the rolling bracket 341 on the ball bearing mounting surface 342. Ball bearing assemblies 344 are disposed at the ball bearing mounting grooves 343, and all ball bearing assemblies 344 together form a rolling mating surface for rolling contact with the bottom wall of the switchgear. Therefore, it can better support the bottom wall of the switchgear.

[0160] The rolling support 341 is made of materials such as channel steel, and is therefore easy to manufacture.

[0161] Seen in Figure 37The ball assembly 344 includes a ball mounting base 351. One end of the ball mounting base 351 forms a ball mounting base insertion section 352 for fixedly engaging with the ball mounting groove 343. The mounting base insertion section 352 and the ball mounting groove 343 can be fixedly connected by means such as interference fit, welding, or threaded connection. In a preferred embodiment, they can be engaged by a threaded connection, thus better realizing the detachable engagement of the ball assembly 344, and thus better realizing the repair or direct replacement of the ball assembly 344 when it fails. The other end of the ball mounting base 351 extends outward to form a ball mounting base assembly section 353 that engages with the ball mounting surface 342. The arrangement of the ball mounting base assembly section 353 allows the weight borne by the ball assembly 344 to be better applied to the rolling support 341, thus improving the stress performance. The other end of the ball bearing mounting base 351 forms a hemispherical ball bearing mounting groove 354, within which a ball bearing 355 is rolled. This design allows the ball bearing 355 to provide rolling contact in any direction on the rolling contact surface, thus better meeting the multi-directional movement requirements of the switchgear above the rolling assembly 311. The upper end of the ball bearing mounting groove 354 also has a countersunk groove 356, where a ball bearing limiting ring 357 can be fixedly installed to limit the movement of the ball bearing 355 using methods such as interference fit or welding; thus effectively preventing the ball bearing 355 from falling out. Furthermore, a ball-fitting hole 358 is formed in the middle of the limiting ring 357 for engaging with the ball 355. The inner diameter of the ball-fitting hole 358 is smaller than the diameter of the ball 355. Simultaneously, the inner wall of the ball-fitting hole 358 can be constructed as, for example, a spherical arc surface, thus achieving better limiting and rolling engagement with the ball 355. In addition, the diameter of the ball mounting groove 354 can be larger than the diameter of the ball 355, and multiple small balls (not shown in the diagram) with diameters no larger than the difference between the diameters of the ball mounting groove 354 and the ball 355 can be arranged within the ball mounting groove 354, thus further improving the smoothness of the ball 355's rolling.

[0162] Seen in Figure 38The lifting assembly 312 includes a lifting link assembly 361, which includes a lifting link mounting seat 371 for engaging with the bottom wall of the rolling assembly 311. Two lifting arms 372 forming an included angle in the vertical plane are hinged to the lifting link mounting seat 371. One end of the lifting arm 372 is hinged to the lifting link mounting seat 371, and the other end of the lifting arm 372 is rotatably engaged with a drive pin 373. The drive pin 373 has a drive screw hole 374 in the middle for threaded engagement with the same drive screw 362. The drive screw 362 is driven to rotate by the drive assembly 314. This allows the lifting control of the rolling assembly 311 to be better converted into the rotation control of the driving screw 362 through the lifting linkage assembly 361 and the drive screw 362. In addition to reducing the force required for the lifting control of the rolling assembly 311, it can also fully take into account the environment of limited space inside the compartment, so that the lifting control of the rolling assembly 311 can be realized from the outer space of the area occupied by the corresponding switchgear. Therefore, it is better suited for use in compartment substations.

[0163] The drive screw 362 and the bracket assembly 313 can be connected by a bearing.

[0164] In this embodiment, the extension direction of the drive screw 362 is parallel to the extension direction of the rolling assembly 311, and the lifting assembly 312 has at least two components spaced apart. Therefore, it can better support the rolling assembly 311, especially better ensure that the rolling mating surface of the rolling assembly 311 remains horizontal during the lifting process, thus better ensuring that the switch cabinet does not tilt during the lifting process.

[0165] In practice, due to the need for parallel placement of adjacent switchgear, the gap between them needs to be kept small. If the switchgear tilts during lifting or lowering, it may directly prevent it from being properly positioned or moved. Specifically:

[0166] During the initial installation of switchgear, when any switchgear reaches the installation position, the gap between it and the already installed switchgear is already small. If any switchgear tilts during descent, it is easy for its center of gravity to deviate. Furthermore, due to the large weight of a single switchgear and the small rolling friction at the bottom, if the switchgear tilts during descent, it is very easy for the bottom of the switchgear to slip. This slippage will directly cause the switchgear to deviate from the intended installation position when it is lowered into place.

[0167] Similarly, when all switchgear has been installed but any switchgear needs to be inspected and adjusted, if the switchgear is offset, it will put pressure on the adjacent switchgear or the inner wall of the compartment. The friction caused by this pressure will directly hinder the switchgear from continuing to rise or fall, thus affecting the raising and lowering of the switchgear.

[0168] For any switchgear, the device body 310 in this embodiment can be used in pairs, that is, one device body 310 can be set on the left and right sides of each switchgear. The lifting and lowering of the switchgear is realized through the coordinated operation of the two device bodies. For each device body 310, its rolling component 311 can be set along the front-back direction of the switchgear. It is understood that the tilting of the switchgear includes tilting in the front-back direction and tilting in the left-right direction. By setting at least two lifting components 312 at the drive screw 362, the horizontal position of the switchgear in the front-back direction during the lifting and lowering process can be better maintained.

[0169] In addition, the bracket assembly 313 in this embodiment can also form a guide channel that extends vertically to cooperate with the corresponding end of the rolling assembly 311, thus further ensuring the horizontal position of the switch cabinet in the front-to-back direction during the lifting and lowering process.

[0170] In this embodiment, a load-bearing component 315 for supporting the lifting component 312 is also provided at the support assembly 313. The load-bearing component 315 includes a load-bearing plate 363 with both ends fixedly connected to different support assemblies 313, and a load-bearing connecting rod assembly 364 disposed between the load-bearing plate 363 and the lifting component 312. The load-bearing connecting rod assembly 364 includes two load-bearing arms 375 and a load-bearing connecting rod mounting seat 376. Both ends of the load-bearing arms 375 are hinged to the corresponding drive pins 373 and the load-bearing connecting rod mounting seat 376, respectively. A guide post 378 is provided at the lower end of the load-bearing connecting rod mounting seat 376. A guide hole 365 for clearance fit with the corresponding guide post 378 is provided at the guide post 378. A load-bearing spring 366 is sleeved between the load-bearing plate 363 and the load-bearing connecting rod mounting seat 376. The load-bearing spring 366 is used to transmit the force at the load-bearing connecting rod mounting seat 376 to the load-bearing plate 363. Therefore, when the rolling component 311 is in the rising state, the load-bearing component 315 can better bear all or part of the weight of the switch cabinet. This can better reduce the load at the drive screw 362, and thus better avoid problems such as deformation, reduced accuracy, and shortened lifespan that may occur to the drive screw 362.

[0171] Understandably, when the main body 310 of the device is non-removably installed in the cabin, the support assembly 313 can be fixedly connected to the bottom frame by means such as welding. Since the load-bearing plate 363 is fixedly connected to the support assembly 313, the load at the drive screw 362 can be better distributed by the bottom frame. When the main body 310 of the device is detachably installed in conjunction with the cabin, the main body 310 of the device can be directly installed on the ground foundation, and the ground foundation can bear the relevant load.

[0172] Seen in Figure 40The drive assembly 314 includes a housing assembly 381 and a worm gear assembly 382 disposed within the housing assembly 381. The worm gear assembly 382 includes a worm gear 383 for cooperating with the drive screw 362 and a worm 384 for transmitting external power. Therefore, it can better drive the drive screw 362.

[0173] In this embodiment, when the main body 310 is non-removably mounted on the cabin, the drive assembly 314 can be positioned in front of the corresponding switch cabinet. In this case, the housing assembly 381 can be directly fixed to the corresponding position on the bottom frame using methods such as welding. Therefore, the installation of the drive assembly 314 can be achieved more efficiently.

[0174] Seen in Figure 41 The worm gear 384 includes a worm body 391, within which a power transmission shaft mounting groove 392 is axially arranged. A power transmission shaft 393 is rotatably mounted within the power transmission shaft mounting groove 392. The power transmission shaft 393 engages with the worm body 391 via at least one locking pin assembly 394. The locking pin assembly 394 has a locked position and an unlocked position. In the locked position, the power transmission shaft 393 and the worm body 391 are relatively fixed in the circumferential direction. In the unlocked position, the power transmission shaft 393 and the worm body 391 are relatively rotatable in the circumferential direction. Therefore, the transmission of power from the automatic power transmission shaft 393 to the worm body 391 can be achieved more effectively.

[0175] Seen in Figure 43 and Figure 44 The locking pin assembly 394 includes a first locking pin 394a and a second locking pin 394b that cooperate with each other, and a locking pin spring 394c for maintaining the first locking pin 394a and the second locking pin 394b having a tendency to move away from each other.

[0176] The inner wall of the power transmission shaft mounting groove 392 is provided with a locking pin mating groove 392a that extends axially and is used to mate with the first locking pin 394a. The first locking pin 394a has a first guide slope 394a1 formed on both sides in the circumferential direction to mate with the locking pin mating groove 392a. The radial extension length of the first guide slope 394a1 is greater than the radial depth of the locking pin mating groove 392a.

[0177] The second locking pin 394b has a locking pin mating part 394b1 and a locking pin transmission part 394b2 for mating with the first locking pin 394a. A wrench hole 395 is formed axially in the middle of the power transmission shaft 393. A locking pin mounting groove 393a is provided on the lower side wall of the power transmission shaft 393, which extends axially and is used to mat with the second locking pin 394b. The locking pin mounting groove 393a has a first stepped groove 393a1 for clearance mating with the locking pin mating part 394b1, and a second stepped groove 393a2 formed on the bottom wall of the first stepped groove 393a1 for clearance mating with the locking pin transmission part 394b2.

[0178] The locking pin drive part 394b2 extends into the wrench hole 395, and the end of the locking pin drive part 394b2 facing the opening of the wrench hole 395 forms a second guide slope 394b3.

[0179] The above structure allows the first guide slope 394a1 to engage with the locking pin groove 392a under natural conditions due to the action of the locking pin spring 394c, and the locking pin transmission part 394b2 to extend into the wrench hole 395. At this time, the locking pin assembly 394 is in the unlocked position, that is, in the unlocked position, the elastic force of the locking pin spring 394c provides resistance to the relative rotation between the power transmission shaft 393 and the worm gear body 391 in the circumferential direction; and when the power transmitted to the power transmission shaft 393 is large enough or the resistance received is large enough, relative rotation can occur between the power transmission shaft 393 and the worm gear body 391.

[0180] Therefore, when the two main bodies 310 are arranged in a coordinated manner on the left and right sides of the switch cabinet, tools such as wrenches can be inserted into the upper part of the corresponding wrench holes 395 at the same time. By turning the wrench, power can be supplied to the power transmission shaft 393 at the same time, so as to achieve the synchronous lifting and lowering of the rolling components 311 at the two main bodies of the device. Thus, the left and right tilting of the switch cabinet during the lifting and lowering process can be better avoided.

[0181] Considering that the two main body 310s are independently configured, it is difficult to achieve synchronous rotation of the corresponding power transmission shaft 393 in actual operation. Therefore, this embodiment provides a locking pin assembly 394. By setting the number of locking pin assemblies 394 and the parameters of the locking pin spring 394c, the following can be achieved during the coordinated lifting and lowering of the two main body 310s:

[0182] If the switch cabinet does not tilt in the left and right directions, the pressure on the two main bodies 310 of the device is balanced. At this time, the locking pin spring 394c can keep the power transmission shaft 393 and the worm gear body 391 relatively fixed in the circumferential direction; thus, the switch cabinet can be raised more smoothly.

[0183] If the switchgear tilts in the left-right direction, the pressure on the two main body 310s will be unbalanced. At this time, the rotation of the worm gear body 391 at the main body 310 under greater pressure will be subject to greater resistance, thus forcing the first locking pin 394a to disengage from the locking pin mating groove 392a. At this time, the force transmission shaft 393 and the worm gear body 391 will rotate relative to each other in the circumferential direction. At this time, the rolling component 311 at the main body 310 under less pressure can be lowered, which can better achieve the rebalancing of the forces between the two main body 310s. Therefore, it is better to adjust the switchgear in time when it tilts in the left-right direction.

[0184] In addition, during actual operation, the switchgear may jam due to excessive lifting or lowering. In this case, a tool such as a wrench can be inserted into the lower part of the corresponding wrench hole 395. By pressing the locking pin transmission part 394b2 with the tool such as the wrench, the first locking pin 394a can be forced to remain in the locking pin mating groove 392a. Therefore, the lifting or leveling of the switchgear can be better achieved when jamming occurs.

[0185] In this embodiment, the cross-section of the wrench hole 395 can be constructed into a regular hexagon, thus enabling it to better fit with an internal hex wrench of a matching size.

[0186] In this embodiment, the first locking pin 394a and the locking pin mating part 394b1 are respectively provided with locking pin spring post 394d and locking pin spring hole 394e for mating with both ends of the locking pin spring 394c, and the locking pin spring post 394d can extend into the locking pin spring hole 394e, so the assembly of the locking pin spring 394c can be better realized.

[0187] Furthermore, the depth of the first stepped groove 393a1 is configured to fully accommodate the first locking pin 394a and the locking pin mating portion 394b1; in use, the sum of the thicknesses of the first locking pin 394a and the second locking pin 394b is configured to be greater than the sum of the depths of the locking pin mating groove 392a and the first stepped groove 393a1. Therefore, the locking pin assembly 394 can be better positioned to have both a locked and unlocked posture.

[0188] Example 7

[0189] This embodiment provides a modular substation, which differs from Embodiment 1 in that the switchgear relocation device in Embodiment 6 is fixedly installed at the bottom frame 10 of the main body of the substation.

[0190] Specifically, for any switchgear, the main body 310 is used in pairs, that is, one main body 310 is set on the left and right sides of each switchgear. The switchgear is raised and lowered through the coordinated operation of the two main bodies 310. For each main body 310, its rolling component 311 can be set along the front and rear direction of the switchgear. This allows for better assembly and maintenance of the switchgear inside the compartment.

[0191] Meanwhile, during the assembly and commissioning of a modular substation according to this embodiment, the switchgear is raised and lowered through the coordinated operation of the two main device bodies 310. Therefore, the assembly and maintenance of the switchgear within the compartment can be achieved more effectively.
