Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a BIM-based prefabricated construction equipment. Background Technology

[0002] BIM-based prefabricated construction equipment is a new type of intelligent equipment that integrates building information modeling technology with prefabricated construction technology. By deeply integrating geometric information, material properties, and construction process data in the BIM model, it enables precise, automated, and collaborative management of prefabricated component production, transportation, hoisting, and installation. This can improve construction efficiency, reduce error rates, and optimize resource allocation. As the core hub for power supply and distribution of prefabricated construction equipment, the performance of the distribution box directly affects the stability of equipment operation and construction safety.

[0003] A search revealed Chinese patent publication number CN214413376U, which discloses a BIM-based prefabricated construction equipment and its usage method. The equipment includes a housing with a drive motor mounted on the top of its inner cavity. The output of the drive motor is connected to a fan blade via bolts. This invention first sets the monitoring parameters of a temperature sensor via a control panel. The control panel sends the data to a processor, which then displays the data on a screen. After confirming the accuracy of the input data, the processor saves the data and sends it to the temperature sensor. When the temperature sensor detects a predetermined value, it sends the data back to the processor, which then activates the drive motor and electric telescopic rod. The processor, control panel, display screen, and temperature sensor facilitate automatic control of the drive motor and electric telescopic rod. The drive motor then rotates the fan blade. A mounting bracket facilitates the disassembly and installation of the drive motor. However, the distribution box, as the core hub for power supply and distribution in prefabricated construction equipment, needs to be transported during construction. This equipment lacks a collision protection mechanism, and the cable connectors on the outside of the distribution box are susceptible to damage during transport due to collisions. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a BIM-based prefabricated construction equipment, which aims to improve the existing technology by addressing the lack of anti-collision mechanisms and the fact that the external cable connectors of the housing are subject to collisions during transportation, resulting in damage to the connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a BIM-based prefabricated construction equipment, including a box, a cable plug fixedly connected to the lower middle part of the rear side of the outer wall of the box, a protective mechanism provided on the front side of the cable plug, the protective mechanism being used to protect the cable plug from bumps during transportation, and a heat dissipation mechanism provided inside the box, the heat dissipation mechanism being used to cool the box by air.

[0006] The protective mechanism includes two bearing seats. The outer walls of the two bearing seats are fixedly connected to the rear side of the outer wall of the housing. The inner walls of the two bearing seats are rotatably connected to the same rotating shaft. The outer wall of the rotating shaft is fixedly connected to a protective shell. A buckle is fixedly connected to the front side of the outer wall of the protective shell. A buckle hole is provided on the rear side of the outer wall of the housing. Angle components are provided at both the left and right ends of the rotating shaft. A locking component is provided on the outer wall of the protective shell.

[0007] Through the above technical solution: the fixed connection between the shaft seat and the housing provides a stable installation foundation for the entire protection mechanism; the rotational cooperation between the shaft and the shaft seat allows the protective shell to open and close flexibly with it as the axis, facilitating the operation and protection of the cable plug; the setting of the buckle and buckle hole provides temporary positioning when the protective shell is closed, preventing accidental shaking and initially ensuring the stability of the protection; the addition of the angle component and locking component further improves the reliability of the protection mechanism; the angle component precisely limits the rotation angle of the protective shell, ensuring the accuracy of its opening and closing positions; the locking component can achieve a stable lock in both the open and closed states of the protective shell, preventing the cable plug from being damaged by collision or shaking during equipment handling.

[0008] As a further description of the above technical solution:

[0009] The heat dissipation mechanism includes two fan shrouds, the outer walls of which are fixedly connected to the left and right sides of the inner wall of the housing. Multiple air inlets are provided on the left and right sides of the outer wall of the housing. Multiple conical channels are provided on the outer walls of the two fan shrouds.

A fan is fixedly connected to the inner wall of the air outlet. Closure components are provided on the left and right sides of the inner wall of the housing.

[0010] The above technical solution, with its layout of hood, air inlet, conical channel, and air outlet, combined with the active exhaust of the fan, forms a stable air circulation path. This quickly removes heat from the enclosure, lowers the internal temperature, and ensures the normal operation of the electrical components inside the equipment. The filter screen can filter dust and impurities in the air, preventing them from damaging the components.

[0011] As a further description of the above technical solution:

[0012] The angle component includes a rotating block, the outer wall of which is fixedly connected to the outer wall of the rotating shaft. The outer wall of the rotating block has a rotating groove. A fixing block is fixedly connected to the right side of the outer wall of the housing, and a semi-circular insert is fixedly connected to the outer wall of the fixing block.

[0013] Through the above technical solution, the angle component achieves precise control of the rotation angle of the protective shell. The rotating block rotates synchronously with the rotating shaft. The shape of the rotating groove and the semi-circular insert matches, limiting the rotation angle of the protective shell to 90 degrees upward, preventing excessive rotation, ensuring the accurate position of the protective shell when opening and closing, and improving the stability and protective effect of the protection mechanism.

[0014] As a further description of the above technical solution:

[0015] The locking assembly includes two locking plates, the outer walls of which are fixedly connected to the front and bottom of the outer wall of the protective shell, respectively. The inner wall of the housing is rotatably connected to two locking shafts, and the front of each locking shaft is fixedly connected to a locking block. The inner wall of the housing is fixedly connected to multiple limiting blocks.

[0016] Through the above technical solution, the locking plate, locking shaft, locking block and limiting block cooperate with each other to achieve a stable lock in both the open and closed states of the protective shell, preventing accidental opening or loosening, effectively protecting the cable plug from collision damage during transportation, and enhancing the safety of the protection mechanism.

[0017] As a further description of the above technical solution:

[0018] The closing assembly includes multiple rotating blades, the outer walls of which are rotatably connected to the inner walls of multiple air inlets. Two traction blocks are fixedly connected to the outer walls of each of the multiple rotating blades. A sliding groove is provided on the outer wall of the housing, and a slide frame is slidably connected to the inner wall of the sliding groove. Multiple traction grooves are provided on the outer wall of the slide frame. A screw is fixedly connected to the top of the slide frame, and a screw block is threadedly connected to the outer wall of the screw.

[0019] Through the above technical solution, the operator can drive the slide along the slide rail by rotating the rotating block, and then control the rotation of the blade through the traction groove and traction block to open or close the air inlet, so as to meet the different needs of heat dissipation during equipment operation and protection during handling, and improve the practicality of the heat dissipation mechanism.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the semi-circular insert is rotatably connected to the inner wall of the rotating groove, and the outer wall of the buckle is slidably connected to the inner wall of the buckle hole.

[0022] Through the above technical solution, the cooperation between the semi-circular plug and the rotating slot precisely limits the rotation angle of the protective shell, and the plug and the buckle hole play a temporary fixing role when the protective shell is closed. The two work together to ensure the stability and accuracy of the opening and closing process of the protective shell, and provide reliable protection for the cable plug.

[0023] As a further description of the above technical solution:

[0024] The outer walls of the two locking shafts are slidably connected to the inner walls of the two locking plates, and the outer walls of the two locking shafts are rotatably connected between the adjacent two limiting blocks.

[0025] Through the above technical solution, the locking shaft, locking plate and limiting block work together to enable the locking assembly to stably lock the opening and closing state of the protective shell, preventing it from loosening or opening due to external force during transportation, and effectively protecting the safety of the cable plug.

[0026] As a further description of the above technical solution:

[0027] The traction block is slidably connected to the inner wall of the traction groove, and the outer wall of the rotating block is rotatably connected to the inner wall of the box.

[0028] The above technical solution, through the sliding cooperation between the traction block and the traction groove, converts the rotational motion of the swivel block into the rotation of the blades, thereby realizing the opening and closing control of the air inlet. The structure is ingeniously designed, easy to operate, and ensures the normal operation of the heat dissipation mechanism under different working conditions.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the rotating connection structure between the shaft seat and the rotating shaft allows the protective shell to open and close flexibly with the rotating shaft as the axis, which facilitates the operation and protection of the cable plug. Combined with the temporary fixing design of the buckle and the buckle hole, the protective shell can effectively prevent accidental shaking when closed, thus initially ensuring the stability of the protection.

[0031] 2. In this utility model, by fixing the fan covers on the left and right sides of the inner wall of the box, and cooperating with the layout design of the air inlet, conical channel and air outlet opened on the outer wall, the outside cold air can enter through the air inlet, be evenly dispersed under the guidance of the conical channel, flow through the inside of the box and be discharged through the air outlet, forming an efficient air-cooling circulation path, effectively reducing the temperature inside the box and ensuring the stable operation of electrical components.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See attached document Figure 2 Appendix Figure 3 and attached Figure 4 The present invention provides an embodiment of a BIM-based prefabricated construction equipment, including a box 1. A cable plug 2 is fixedly connected to the lower middle part of the rear side of the outer wall of the box 1. A protective mechanism 3 is provided on the front side of the cable plug 2. The protective mechanism 3 is used to protect the cable plug 2 from bumps during transportation. A heat dissipation mechanism 4 is provided inside the box 1. The heat dissipation mechanism 4 is used to cool the box 1 by air cooling.

[0042] The protective mechanism 3 includes two bearing seats 301. The outer walls of the two bearing seats 301 are fixedly connected to the rear side of the outer wall of the housing 1, providing an installation base and stable support for the rotating shaft 302. The inner walls of the two bearing seats 301 are rotatably connected to the same rotating shaft 302, allowing the rotating shaft 302 to rotate flexibly around the bearing seats 301. The outer wall of the rotating shaft 302 is fixedly connected to a protective shell 303, thereby driving the protective shell 303 to open and close, providing a protective space for the cable plug 2. A buckle 304 is fixedly connected to the front side of the outer wall of the protective shell 303, and a buckle hole 305 is provided on the rear side of the outer wall of the housing 1. The outer wall of the 4 is slidably connected to the inner wall of the buckle hole 305. When the protective shell 303 is closed, the two cooperate to achieve temporary positioning and prevent the protective shell 303 from shaking accidentally. Angle components 306 are provided at both ends of the rotating shaft 302 to precisely limit the rotation angle of the protective shell 303. The angle component 306 includes a rotating block 3061. The outer wall of the rotating block 3061 is fixedly connected to the outer wall of the rotating shaft 302 and can rotate synchronously with the rotating shaft 302. The outer wall of the rotating block 3061 is provided with a rotating groove 3062. A fixing block 3063 is fixedly connected to the right side of the outer wall of the box 1. A semi-circular part is fixedly connected to the outer wall of the fixing block 3063. The outer wall of the semi-circular insert 3064 is rotatably connected to the inner wall of the rotating groove 3062. The shape of the rotating groove 3062 and the semi-circular insert 3064 matches, limiting the rotation angle of the protective shell 303 to 90 degrees upwards, ensuring the accuracy of the opening and closing states. The outer wall of the protective shell 303 is provided with a locking assembly 307 to securely lock the open and closed states of the protective shell 303. The locking assembly 307 includes two locking plates 3071, whose outer walls are respectively fixedly connected to the front and bottom of the outer wall of the protective shell 303, for engagement with the locking structure inside the housing 1. The wall is rotatably connected to two locking shafts 3072, and a locking block 3073 is fixedly connected to the front side of each locking shaft 3072. Multiple limiting blocks 3074 are fixedly connected to the inner wall of the housing 1. The outer walls of the two locking shafts 3072 are slidably connected to the inner walls of the two locking plates 3071. The outer walls of the two locking shafts 3072 are rotatably connected between the adjacent two limiting blocks 3074. By rotating the locking blocks 3073, sliding the locking plates 3071 and limiting blocks 3074 to limit the rotation of the locking shafts 3072, reliable locking of the protective shell 303 in the open and closed state is achieved, preventing the cable plug 2 from being damaged by collision during transportation.

[0043] Specifically, two bearing seats 301 are fixed to the rear side of the outer wall of the housing 1 and are rotatably connected to the rotating shaft 302, driving the protective shell 303 to rotate. The buckle 304 on the front side of the protective shell 303 is initially positioned with the buckle hole 305 of the housing 1. In the angle component 306, the shape of the semi-circular insert 3064 and the rotating groove 3062 restricts the protective shell 303 to rotate upwards by 90 degrees when it is opened. When the protective shell 303 is closed, the bottom locking plate 3071 cooperates with the bottom locking component 307. When the protective shell 303 is opened, the front locking plate 3071 cooperates with the top locking component 307. When the locking assembly 307 is locking, the locking block 3073 is first rotated to match the shape of the inner wall of the locking plate 3071. Then, the protective shell 303 is rotated, and the locking plate 3071 passes through it. Then, the locking plate 3071 is rotated 90 degrees clockwise. At this time, the locking plate 3071 is restricted to the outer wall of the locking shaft 3072. When the locking plate 3071 is rotated, the two limit blocks 3074 restrict the rotation range of the locking shaft 3072, so that the locking plate 3071 can quickly rotate to the position opposite to the inner wall of the locking plate 3071 and lock the locking plate 3071.

[0044] See attached document Figure 2 Appendix Figure 3 and attached Figure 5 The heat dissipation mechanism 4 includes two fan shrouds 401. The outer walls of the two fan shrouds 401 are fixedly connected to the left and right sides of the inner wall of the housing 1, respectively, to form the main airflow channel and guide the airflow within the housing 1. Multiple air inlets 402 are provided on both the left and right sides of the outer wall of the housing 1, serving as inlets for outside cold air to enter the housing 1 and ensuring the supply of cooling air. Multiple conical channels 403 are provided on the outer walls of both fan shrouds 401. The conical structure guides the airflow to be evenly dispersed, improving the airflow efficiency within the housing. Filters 40 are fixedly connected to the inner walls of both fan shrouds 401. 4. It can intercept and filter dust and impurities in the air to prevent them from entering the interior of the housing 1 and damaging electrical components. An air outlet 405 is provided on the upper rear side of the outer wall of the housing 1 to provide an outlet path for hot air to be discharged. A fan 406 is fixedly connected to the inner wall of the air outlet 405. The fan generates negative pressure through operation to actively draw out hot air from the housing and at the same time promote the entry of cold air from the air inlet 402 to form a continuous air-cooling cycle. Closure components 407 are provided on the left and right sides of the inner wall of the housing 1 to control the ventilation status of the heat dissipation mechanism 4 and meet the different needs of equipment operation and handling.

[0045] Specifically, when the heat dissipation mechanism 4 is running, the rotating block 4077 is in a fixed position in the initial state, the slide 4074 is located below the slide groove 4073, the traction groove 4075 cooperates with the traction block 4072 to make the rotating blade 4071 open, the air inlet 402 is fully open, after the fan 406 is started, the outside cold air enters through the air inlet 402, passes through the conical channel 403 and the filter screen 404 of the fan cover 401 in sequence, flows through the inside of the box 1 to take away the heat, and finally is discharged from the air outlet 405 to achieve air cooling.

[0046] See attached document Figure 1 Appendix Figure 5 and attached Figure 6 The closing assembly 407 includes multiple rotating blades 4071. The outer wall of each rotating blade 4071 is rotatably connected to the inner wall of multiple air inlets 402. Rotation opens or closes the air inlets 402. Two traction blocks 4072 are fixedly connected to the outer wall of each rotating blade 4071 to cooperate with the carriage 4074, converting the linear motion of the carriage 4074 into the rotation of the rotating blades 4071. A sliding groove 4073 is provided on the outer wall of the housing 1 to provide a sliding track for the carriage 4074, ensuring its stability and guidance. The carriage 4074 is slidably connected to the inner wall of the sliding groove 4073, and the sliding motion drives the traction groove 4075 to move. The drive vane 4071 is driven by a slide 4074 with multiple traction grooves 4075 on its outer wall, which are slidably connected to the traction block 4072 to transmit force and control the rotation angle of the vane 4071. A screw 4076 is fixedly connected to the top of the slide 4074, and a rotating block 4077 is threadedly connected to the outer wall of the screw 4076. By rotating the rotating block 4077, the slide 4074 is driven to slide up and down along the slide groove 4073 using the thread transmission principle. The outer wall of the rotating block 4077 is rotatably connected to the inner wall of the housing 1, providing an operating component for the operator to manually control the movement of the slide 4074 and the opening and closing state of the air inlet 402.

[0047] Specifically, when the equipment needs to be moved, the operator rotates the rotating block 4077. Through the threaded transmission between the screw 4076 and the rotating block 4077, the slide 4074 is driven to slide upward in the slide groove 4073. When the slide 4074 moves, the traction groove 4075 pulls the traction block 4072, driving the rotating blade 4071 to rotate on the inner wall of the air inlet 402 until it completely covers the air inlet 402, closing the ventilation channel. In this state, the air circulation between the inside of the housing 1 and the outside is blocked, which can prevent dust and debris from entering during the handling process and protect the heat dissipation mechanism 4 from collision damage. After the equipment reaches the designated position, the rotating block 4077 is rotated again to reset the slide 4074, reopen the air inlet 402, and restore the heat dissipation function.

[0048] Working principle: The bearing seat 301 is fixed, and the rotating shaft 302 is rotatably connected to the bearing seat 301, providing a rotation fulcrum for the protective shell 303, allowing the protective shell 303 to open and close around the rotating shaft 302. The front side of the outer wall of the protective shell 303 has a snap fastener 304, and the rear side of the outer wall of the housing 1 has a buckle hole 305. When the protective shell 303 is closed, the snap fastener 304 inserts into the buckle hole 305, providing temporary fixation and preventing accidental shaking of the protective shell 303. The angle component 306 precisely restricts the movement of the protective shell. The rotation angle of 303 is controlled by a rotating block 3061 fixed to the outer wall of the rotating shaft 302, which has a rotating groove 3062. A fixing block 3063 is located on the right side of the outer wall of the housing 1, with a semi-circular insert 3064 on top. Due to the special shape design of the rotating groove 3062 and the semi-circular insert 3064, the protective shell 303 can only rotate upwards by ninety degrees. When the protective shell 303 is open, the rear wall of the rotating groove 3062 contacts the semi-circular insert 3064, restricting its continued rotation. When closed, the upper part of the rotating groove 3062... The wall and the semi-circular insert 3064 cooperate to ensure that the protective shell 303 can tightly cover the cable plug 2. The locking component 307 can securely lock the open and closed state of the protective shell 303. There is a locking plate 3071 on the front and bottom of the outer wall of the protective shell 303. The inner wall of the housing 1 contains a locking shaft 3072, a locking block 3073 and a limiting block 3074. When locking the protective shell 303, first rotate the locking block 3073, then rotate the protective shell 303 so that the locking plate 3071 passes through the locking block 3073, and then... The locking block 3073 is locked by rotating the locking block 3073. The limiting block 3074 restricts the rotation range of the locking shaft 3072, ensuring that the locking block 3073 is accurately rotated to the locking position. When the protective shell 303 is closed, the bottom locking plate 3071 cooperates with the bottom locking component 307. When it is open, the front locking plate 3071 cooperates with the top locking component 307, ensuring the stability of the protective shell 303 and preventing the cable plug 2 from being damaged by collision or shaking during transportation, thus providing reliable safety protection.

[0049] Furthermore, two fan hoods 401 are fixed to the left and right sides of the inner wall of the housing 1, respectively, serving as the main airflow channels. Multiple air inlets 402 on the left and right sides of the outer wall of the housing 1 provide entry points for cold air. The conical channel 403 on the outer wall of the fan hood 401 guides the airflow to disperse evenly, increasing the airflow speed within the housing. The filter 404 on the inner wall of the fan hood 401 filters dust and impurities from the air, preventing them from entering the housing 1 and affecting the normal operation of electrical components. The air outlet 404 is located in the upper middle part of the rear side of the outer wall of the housing 1. 5. A fan 406 is installed. When the fan 406 operates, it creates negative pressure, drawing out hot air from the box and simultaneously prompting outside cold air to enter through the air inlet 402, forming a continuous air circulation to achieve air cooling. The closing component 407 controls the ventilation status of the heat dissipation mechanism 4. During normal operation, the rotating block 4077 is in its initial position, the slide 4074 is located below, and the traction groove 4075 drives the traction block 4072 to open the rotating blade 4071, fully opening the air inlet 402. The fan 406... After startup, cold outside air enters through inlet 402, passes through conical channel 403 and filter 404, flows through the interior of housing 1 to carry away heat, and is finally discharged through outlet 405. This continuous airflow circulation effectively reduces the internal temperature of housing 1. When the equipment needs to be moved, the operator rotates the rotary block 4077. Due to the threaded connection between the rotary block 4077 and screw 4076, screw 4076 drives the slide 4074 to slide downwards in the slide groove 4073. As the slide 4074 moves, the traction groove 4075... Pull the traction block 4072, which in turn drives the rotating blade 4071 to rotate on the inner wall of the air inlet 402 until the rotating blade 4071 completely covers the air inlet 402 and closes it. At this time, the air circulation between the inside of the housing 1 and the outside is blocked, which can prevent dust and debris from entering the housing 1 during transportation, and at the same time avoid damage to the components at the air inlet 402 due to collision, thus protecting the integrity of the heat dissipation mechanism 4. After the equipment reaches the designated position, rotate the rotating block 4077 again to reopen the air inlet 402 and restore the heat dissipation function.
