Description

Technical Field

[0001] This invention relates to a modular prefabricated substation, belonging to the technical field of prefabricated substations. Background Technology

[0002] A prefabricated substation is a power supply equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices into a single unit. Modular prefabricated substations are easy to install, disassemble, and maintain, and are widely used in mines, factories, oil and gas fields, and wind power stations.

[0003] The heat dissipation holes of existing prefabricated substations are usually located on the side wall of the substation. The number of heat dissipation holes is small, which affects the heat dissipation efficiency and makes it easy for rainwater to enter the interior of the enclosure.

[0004] Chinese patent CN204271514U discloses a waterproof box-type substation, which solves the problem that in the event of natural disasters such as floods and torrential rains, when the water level is high and a large amount of water enters the box-type substation, it will cause damage to the box-type substation over a large area.

[0005] However, waterproofing by raising the height of the substation can lead to a top-heavy situation due to the substation's heavy weight, resulting in insufficient stability under the impact of water flow. Summary of the Invention

[0006] The purpose of this invention is to provide a modular prefabricated substation to solve the problems mentioned in the background art.

[0007] The technical solution of the present invention is as follows:

[0008] A modular prefabricated substation includes:

[0009] The base has a closed-loop receiving groove surrounding the outer side of the frame;

[0010] The frame is detachably installed on the top of the base, and the frame is equipped with a module plate and a box door; the box top is detachably covered on the top of the frame, and the bottom of the box top and near the edge are provided with heat dissipation vents, and the inner side of the box top is equipped with an automatically retractable spring turntable, and the outer wall of the spring turntable is wrapped with several traction ropes, the other end of which passes through the heat dissipation vents and is connected to the bottom cover.

[0011] The bottom cover is used to cover the matching receiving tank, and a water-blocking component is connected between the bottom cover and the receiving tank;

[0012] The water-blocking component unfolds to enclose the skeleton, and the water-blocking component folds up and is stored in the receiving groove.

[0013] Preferably, the water-blocking component includes an outer layer and an inner layer, and a crisscrossing isolation net connects the outer layer and the inner layer. The crisscrossing isolation net divides the outer layer and the inner layer into multiple independent receiving spaces. Adjacent receiving spaces are connected by a flexible connecting pipe. The inner cavity of the water-blocking component is connected to an air source.

[0014] Preferably, each of the receiving spaces contains a compressible sponge block;

[0015] The end of the connecting tube extends into the sponge block, which contains a water-absorbing and expanding material. The water-absorbing and expanding material absorbs water, expands, and squeezes to close the end of the connecting tube.

[0016] Preferably, the outer wall of the module plate has a rope groove extending from the heat dissipation vent to the receiving groove. Under normal conditions, the traction rope is placed in the rope groove, and a sealing plate for opening or closing the rope groove is also included.

[0017] Preferably, the sealing plate has a first slot on its side wall, and the module plate has a hook that engages with the first slot. It also includes a first elastic element, the elastic force of which pushes the sealing plate toward opening the rope groove.

[0018] The bottom cover has a second slot on its side wall, and the base is provided with a limiting block and a second elastic element. When the bottom cover is closed and the receiving groove is closed, the limiting block is inserted into the second slot.

[0019] Preferably, the outer sidewalls of the module panel and / or the door and / or the top of the box are provided with a moisture-proof layer and an anti-corrosion layer from the inside out, and the inner sidewalls are provided with an explosion-proof layer, a fireproof layer and an insulation layer from the inside out.

[0020] Preferably, a dustproof net is provided on the inner side of the top of the box and above the heat dissipation vent.

[0021] Preferably, a connecting frame is provided at the bottom of the top of the box and near the edge. The connecting frame is snapped into the frame. The connecting frame is provided with a plurality of evenly distributed fixing holes. The connecting frame is connected to the frame with bolts through the fixing holes.

[0022] Preferably, the inner side of the module board is provided with an array of heat-conducting sheets, the top of the frame is provided with a mounting bracket, and the inner side of the mounting bracket is equipped with a cooling fan aligned with the heat-conducting sheets.

[0023] Preferably, the base is provided with lifting rings at the four top corners, and the base is provided with a number of evenly distributed storage holes at the bottom.

[0024] The base is provided with several evenly distributed movable mechanisms, each including a movable sleeve, a spherical wheel, and an adjusting screw, which are used to assist the mechanical movement of the base during hoisting.

[0025] The movable sleeve is located inside the storage hole, the spherical wheel is located at the bottom of the movable sleeve and is movably connected to the movable sleeve, the adjusting screw is located at the top of the movable sleeve, and the movable sleeve passes through the base and is threadedly connected to the base.

[0026] The present invention has the following beneficial effects:

[0027] The heat dissipation vents are positioned at the bottom of the cover, which is relatively high. In the event of natural disasters such as floods or torrential rains, the elastic force of the spring turntable will cause the bottom cover to rise through the traction rope, thereby enabling the water-blocking components to unfold and enclose the frame, preventing water from entering the interior through the gaps between the frame and the module plate and the door.

[0028] The water-blocking component consists of an outer layer, an inner layer, and a protective mesh. Each containment space within the protective mesh is equipped with a sponge. When impacted by external components, the sponge provides cushioning, reducing the probability of puncturing the outer and inner layers.

[0029] Waterproofing is achieved without raising the height of the substation, which helps maintain stability under the impact of water flow. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0046] Example:

[0047] like Figure 1-5 As shown:

[0048] Includes a base 1, a support platform 11 is provided on the top of the base 1 near the center, the edge of the support platform 11 is a sloping structure, which can guide water outward in rainy weather and prevent water from flowing into the inner side of the frame 2. The frame 2 is provided above the support platform 11, the box top 3 is provided above the frame 2, and a connecting frame 31 is provided at the bottom of the box top 3 near the edge, the connecting frame 31 is snapped into the frame 2.

[0049] Several evenly distributed movable mechanisms are provided on the base 1 near the left and right edges. The movable mechanisms include movable sleeves 4, spherical wheels 41 and adjusting screws 42, which are used to assist the mechanical movement of the base 1 during hoisting.

[0050] It should be added that a lifting ring 12 is provided on the top of the base 1 and near the four corners. The lifting ring 12 is rotatably connected to the base 1. Several evenly distributed storage holes 13 are provided on the bottom of the base 1 and near the edge. The lifting ring 12 facilitates the crane to lift and move the prefabricated substation as a whole. When not being moved, the storage holes 13 can store the movable sleeve 4 and the spherical wheel 41.

[0051] Module plates 21 are installed on the rear and left and right sides of the frame 2. Arrayed heat-conducting plates 211 are provided on the module plates 21 and on the inner side of the frame 2. The heat-conducting plates 211 can guide the heat inside the prefabricated substation, facilitating heat dissipation for the electrical equipment inside the substation. Symmetrical box doors 22 are provided on the front side of the frame 2. The box doors 22 are hinged to the frame 2.

[0052] Mounting brackets 23 are welded and fixed to the top of the frame 2 and near the front and rear edges. Cooling fans 24 are installed on the inner side of the mounting brackets 23. Different numbers of cooling fans 24 can be freely installed through the mounting brackets 23. When the cooling fans 24 are running, they can drive the hot air inside the substation to flow upward and be guided through the top of the box top 3 so that the hot air flows out through the heat dissipation port 33 for heat dissipation.

[0053] The connecting frame 31 is provided with several evenly distributed fixing holes 311. The connecting frame 31 is connected to the frame 2 by bolts through the fixing holes 311. The box top 3 is fixed through the connecting frame 31, making the box top 3 flexible and convenient to disassemble and assemble, and facilitating the modular assembly of the substation.

[0054] A reinforcing frame 32 is provided on the inner side of the top of the container 3 and near the top. The reinforcing frame 32 is welded and fixed to the top of the container 3. The structural strength of the top of the container 3 can be enhanced by the reinforcing frame 32.

[0055] The bottom of the top of the enclosure 3 and near the edge are provided with an array of heat dissipation vents 33. A dustproof net 34 is provided on the inner side of the top of the enclosure 3 and above the heat dissipation vents 33. Compared with the heat dissipation design of traditional substations, the heat dissipation vents 33 here can enhance the air flow inside the substation and improve the heat dissipation effect. At the same time, it can effectively prevent rainwater from entering the interior of the substation. The dustproof net 34 can prevent dust from entering above the heat dissipation vents 33.

[0056] The movable sleeve 4 is located inside the receiving hole 13. The spherical wheel 41 is located at the bottom of the movable sleeve 4 and is movably connected to the movable sleeve 4. The adjusting screw 42 is located at the top of the movable sleeve 4. The movable sleeve 4 passes through the base 1 and is threadedly connected to the base 1. When hoisting the substation, rotating the adjusting screw 42 drives the movable sleeve 4 to move, causing the movable sleeve 4 to drive the spherical wheel 41 to move downward, so that the spherical wheel 41 contacts the ground. This can support the base 1 during the hoisting process and facilitate the movement and adjustment of the position of the base 1, thereby improving the hoisting efficiency of the substation.

[0057] In use, after the base 1, frame 2, and top 3 are pre-assembled, the substation is transported to the installation site by a crane. The base 1 is connected to the crane rope by the lifting ring 12. Then, the adjusting screw 42 is rotated to move the movable sleeve 4, which in turn moves the spherical wheel 41 downward, so that the spherical wheel 41 contacts the ground and supports the base 1. Then, the crane suspends and moves the base 1 to the installation platform. The spherical wheel 41 guides the base 1 at the bottom. By pushing the entire substation, the base 1 can be moved, thereby quickly adjusting the position of the base 1. Afterward, the adjusting screw 42 is rotated to move the movable sleeve 4 upward, so that the spherical wheel 41 is stored inside the storage hole 13, which allows the base 1 to support and fix the substation.

[0058] During operation, the heat-conducting plate 211 guides the heat inside the frame 2, causing the cooling fan 24 to run and drive the air inside the substation to flow upward. After being guided through the top of the box 3, the hot air is discharged through the heat dissipation port 33, thereby quickly dissipating heat from the inside of the substation.

[0059] like Figure 6-11 As shown, the spring plate 8 is installed on the inner bottom wall of the box cover 3. Three traction ropes 7 are wrapped around the outer wall of the spring plate 8. The other end of the three traction ropes 7 passes through the heat dissipation hole 33 and is connected to the bottom cover 5. The structure of the bottom cover 5 is adapted to the receiving groove 14. The receiving groove 14 is located on the outside of the frame 2 and is a closed loop structure. The water baffle 6 is a closed loop structure made of flexible material. The lower edge of the water baffle 6 is sealed and fixedly connected to the inner bottom wall of the receiving groove 14, and the upper edge of the water baffle 6 is fixedly connected to the bottom of the bottom cover 5. The water baffle 6 can be folded and hidden inside the receiving groove 14.

[0060] A rope groove 25 is formed on the outer wall of the module plate 21. The sealing plate 26 moves linearly within the module plate 21 to open or close the rope groove 25. The sealing plate 26 is pushed by the elastic force of the first elastic element 27 to open the rope groove 25. A first slot 261 is formed on one side of the sealing plate 26, and a hook 28 is provided inside the module plate 21. Figure 9As shown, the hook 28 has a certain elastic deformation capability. When the sealing plate 26 is manually pushed to close the rope groove 25, the hook 28 engages with the first groove 261.

[0061] like Figure 8 As shown, a limiting block 52 is linearly slidably connected to the inner sidewall of the receiving groove 14. The limiting block 52 tends to bulge out of the receiving groove 14 by the elastic force of the second elastic member 53, and the end of the limiting block 52 has a triangular structure. The sidewall of the bottom cover 5 is provided with a second slot 51. When the bottom cover 5 covers the receiving groove 14, the bottom cover 5 cooperates with the end of the triangular limiting block 52, so that the end of the limiting block 52 is inserted into the second slot 51.

[0062] like Figure 10 As shown, the water-blocking component 6 includes an outer layer 61, an inner layer 62, and an isolation net 63 disposed between the outer layer 61 and the inner layer 62. The isolation net 63 is arranged in a crisscross pattern, dividing the space of the outer layer 61 and the inner layer 62 into multiple independent receiving spaces. Adjacent receiving spaces are connected by flexible connecting pipes. The inner cavity of the water-blocking component is connected to a positive pressure air source (air compressor) and a negative pressure air source, which are installed inside the substation. The connecting pipe 64 can be made of a flexible, deformable material, and a sealing ring is provided on the inner side of its end. The outer layer 61, inner layer 62, and isolation net 63 can be made of PVC plastic with a certain degree of elasticity. The negative pressure air source is used to expel the gas inside the water-blocking component 6, thus reducing its size.

[0063] Under normal circumstances, the traction rope 7 is placed in the rope groove 25 for isolation and protection.

[0064] Working principle:

[0065] In the event of natural disasters such as floods or torrential rains, the receiving tank 14 and rope groove 25 can be opened manually, or the telescopic device can be controlled when the water level is detected by the liquid level sensor to be higher than the set value. The telescopic device will cause the end of the corresponding limit block 52 to disengage from the second slot 51. The telescopic device will cause the corresponding hook 28 to deform and disengage from the first slot 261. Under the push of the elastic force of the first elastic element 27, the sealing plate 26 will open the rope groove 25.

[0066] At this time, under the elastic force of the spring turntable 8, three traction ropes 7 are wound around, thereby driving the bottom cover 5 to rise to the upper limit position, realizing the deployment of the water baffle 6. The deployment of the water baffle 6 will not hinder the normal heat dissipation of the heat dissipation port 33.

[0067] A positive pressure air source inflates the inner cavity of the water-blocking component 6 until the pressure inside the water-blocking component 6 reaches a set value, which can be determined by a pressure sensor; this causes each of the accommodating spaces to inflate and expand, and the squeezed sponge blocks to expand and unfold; this creates a certain distance between the outer layer 61 and the inner layer 62, and the space between the outer layer 61 and the inner layer 62 is filled with sponge blocks.

[0068] During natural disasters such as floods and torrential rains, water flows carrying various hard objects impact the substation. In this case, the inflatable water-blocking component 6 is used to buffer the impact and avoid rigid impact.

[0069] Simultaneously, if a sharp object pierces the outer layer 61, the sponge block acts as a buffer to prevent it from piercing the inner layer 62 at the same time. Water then enters this containment space, and the powdery / block-like water-absorbing and swelling material (a novel sulfurized water-absorbing and swelling polymer material) inside the sponge block absorbs water and expands, further preventing the sharp object from piercing the inner layer 62. At the same time, the water-absorbing and swelling material causes the sponge block to expand, compressing the end of the corresponding connecting tube 64 and closing it. This isolates the containment space corresponding to the pierced outer layer 61 from other containment spaces, ensuring that the containment spaces in other areas still contain gas in an expanded state.

[0070] Furthermore, the water-absorbing and expanding material is also distributed inside the end of the connecting pipe 64, so that after the water-absorbing and expanding material absorbs water and expands, it blocks the end of the connecting pipe 64, and the inside and outside are clamped together to achieve a seal.

[0071] The outer layer of module panel 21 and / or door 22 and / or top 3 is provided with a moisture-proof layer 91, which enables the substation to have a moisture-proof function. The outer layer of moisture-proof layer 91 is provided with an anti-corrosion layer 92, which enables the substation to have corrosion resistance and improve the service life of the substation. The inner layer of module panel 21 and / or door 22 and / or top 3 is embedded with an explosion-proof layer 93 and a fireproof layer 94, which enables the substation to have a fireproof function. The outer layer of fireproof layer 94 is provided with an insulation layer 95, which enables the substation to have an insulation function and prevents leakage of the substation when the series-type high-voltage frequency converter is used.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
