Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically to an underground power distribution cabinet. Background Technology

[0002] A distribution cabinet is a device used for the distribution, control, and protection of electrical energy in a power system. It plays a vital role in the power system, mainly for centralized management and distribution of electrical energy to ensure the stable operation of the power system. Some distribution cabinets are buried underground, which usually require special support and protection measures to ensure the safety and reliability of the equipment.

[0003] Patent application CN201820741335.2 discloses an underground power distribution cabinet, including a trench, a cover plate, and a cabinet body. A water storage tank is located at the bottom of the trench. A spring is installed on the top left side of the cover plate. First drainage holes are evenly spaced on both sides of the cover plate. The bottom of the cover plate is connected to the cabinet body via a heat-conducting plate. A temperature control switch is installed on one side of the cabinet body. Second drainage holes are evenly spaced on the top of the water storage tank. An external drainage pipe is connected to the left side of the water storage tank via a conduit. A water pump is installed on the right side of the bottom of the water storage tank. The water inlet pipe on the pump passes through the top of the water storage tank and extends through the heat-conducting plate, with the end of the water inlet pipe flowing back into the water storage tank. The water inlet pipe is arranged in an S-shape on the heat-conducting plate. This utility model facilitates the storage of the distribution cabinet, reduces the external space occupied, reduces the impact of vibration on the bottom cabinet, and quickly dissipates heat, reducing the impact of heat on the cabinet. However, this device is not convenient or quick to install on larger distribution cabinets, and it is inconvenient to open the distribution cabinet for maintenance. Therefore, an underground distribution cabinet is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an underground power distribution cabinet in response to the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an underground distribution cabinet, including a foundation pit, and further including a cooling device, a drainage device, and a flow-propelling device; a mounting plate is rotatably connected to the inner wall of the foundation pit, a slide rail is fixedly connected to the bottom of the mounting plate, a cabinet body is slidably connected to the surface of the slide rail, a support plate is fixedly connected to the right side of the slide rail, a limit plate is installed on the left side of the slide rail, a threaded rod is threadedly connected to the inner wall of the left side of the slide rail, a cylinder is rotatably connected to the inner wall of the foundation pit, and a mounting block is rotatably connected to the output end of the cylinder; the cooling device is disposed on the inner wall of the foundation pit, the drainage device is disposed on the inner wall of the foundation pit, and the flow-propelling device is disposed on the inner wall of the foundation pit; the top of the support plate is fixedly connected to the bottom of the mounting plate, and the left side of the support plate is in contact with the right side of the cabinet body. The top of the limiting plate contacts the bottom of the mounting plate, the right side of the limiting plate contacts the left side of the cabinet, the inner wall of the limiting plate contacts the surface of the threaded rod, and the top of the mounting block is fixedly connected to the bottom of the mounting plate. When installing the distribution cabinet, the distribution cabinet is mechanically lifted to the upright slide rail, and the cabinet is inserted into the slide rail under the guidance of the employee, so that the cabinet moves to the support plate. Then, the limiting plate is placed on the side of the slide rail away from the support plate, and the threaded rod is driven into the slide rail, thereby realizing the quick installation and fixation of the distribution cabinet. When it is necessary to store the distribution cabinet underground or take it out to the ground, the cylinder will start and drive the mounting block to move. The mounting block will push the mounting plate to rotate, and the mounting plate will drive the cabinet to rotate to store or move it out of the pit, thus facilitating the maintenance of the distribution cabinet by the workers.

[0006] Preferably, the cooling device includes a telescopic rod, a support spring, and a heat-conducting plate. The telescopic rod is installed on the inner wall of the pit, the support spring is sleeved on the surface of the telescopic rod, the heat-conducting plate is fixedly connected to the top of the telescopic rod, and the two ends of the support spring are respectively fixedly connected to the bottom of the heat-conducting plate and the inner wall of the pit. The top of the heat-conducting plate is in contact with the bottom of the cabinet. The cooling device includes a cooling pipe, a water pump, and a hose. The cooling pipe is installed on the inner wall of the heat-conducting plate, the water pump is fixedly connected to the right side of the heat-conducting plate, the hose is fixedly connected to the bottom of the water pump, the bottom of the hose is in contact with the inner wall of the pit, and the output end of the water pump is fixedly connected to the right end of the cooling pipe. When the mounting plate drives the cabinet to rotate into the pit, the cabinet... The body rotates and contacts the heat-conducting plate, pushing the heat-conducting plate downward and compressing the telescopic rod and its surface support spring. At this time, the support spring will lift the heat-conducting plate to support the distribution cabinet, improving the stability of the distribution cabinet after installation. At the same time, the water pump will start and draw rainwater collected in the pit through the hose and introduce it into the cooling pipe. The cooling pipe will cool and dissipate heat on the distribution cabinet body through the heat-conducting plate, thereby improving the heat dissipation effect of the distribution cabinet underground and preventing the distribution cabinet from overheating due to lack of ventilation. If there is no water in the pit, workers can add water manually. Only the lower part of the pit is treated to prevent water leakage. When the water volume exceeds one-third of the pit, water will leak and seep into the surrounding soil to prevent excessive rainwater collection from contacting the distribution cabinet.

[0007] Preferably, the drainage device includes a housing, a movable rod, a stop block, a baffle plate, a drainage hole, and a rope. The housing is fixedly connected to the inner wall of the pit. The movable rod is slidably connected to the inner wall of the housing via a spring. The stop block is fixedly connected to the bottom end of the movable rod. The baffle plate is fixedly connected to the bottom of the stop block. The drainage hole is located at the bottom of the pit. The rope is fixedly connected to the top of the movable rod. The drainage device also includes an inner plate, an outer plate, a limiting rod, and a limiting groove. The outer plate is slidably connected to the inner wall of the pit. The inner plate is slidably connected to the inner wall of the outer plate via a spring. The limiting rod is fixedly connected to the front and rear sides of the inner plate. The limiting groove is located on the inner wall of the pit. The surface of the limiting rod contacts the inner wall of the limiting groove. The top of the inner plate is slidably connected to the bottom of the heat-conducting plate. The surfaces of the stop block and the baffle plate are in contact with the inner wall of the limiting groove. The inner walls of the drainage holes are in contact with each other, and the top of the rope is fixedly connected to the surface of the support plate. When maintenance is required, the mounting plate will rotate and open, causing the support plate to rotate. The support plate will then move the rope upward, which in turn will move the moving rod upward. The moving rod will then move the stop block upward, at which point the stop block will no longer block the drainage hole. Water in the pit will then enter the drainage hole through the outer shell and be discharged, ensuring that all water in the pit is drained. This facilitates subsequent maintenance and repair of the distribution cabinet by employees entering the pit. Simultaneously, when the mounting plate rotates, it will cause the heat-conducting plate to move downward through the cabinet. The heat-conducting plate will then cause the inner plate to move downward within the outer plate. At the same time, the limiting rod on the inner plate is in the limiting groove, so the limiting groove will also guide the limiting rod, causing the limiting rod and the inner plate to move to the right while moving downward. The inner plate will then move the outer plate, which will push the water in the pit towards the drainage hole, improving drainage efficiency.

[0008] Preferably, the telescopic rod mainly consists of an outer rod and an inner rod. The outer rod is fixedly connected to the inner wall of the pit, and the inner rod is slidably connected to the inner wall of the outer rod. An upper inclined block is fixedly connected to the bottom of the inner rod. The surface of the inner rod is slidably connected to the inner wall of the pit, and the top of the inner rod is fixedly connected to the bottom of the heat-conducting plate. The surface of the upper inclined block is slidably connected to the inner wall of the pit. The flow-pushing device includes a sliding rod, a lower inclined block, a rotating rod, a push plate, and a through hole. The sliding rod is slidably connected to the inner wall of the pit, and the lower inclined block is fixedly connected to the right end of the sliding rod. The rotating rod is rotatably connected to the inner wall of the pit via a torsion spring. The push plate is slidably connected to the inner wall of the pit via a spring. The through hole is opened in the inner wall of the pit. The through hole communicates with the drainage hole. The lower surface of the upper inclined block and the upper surface of the lower inclined block are in contact with each other. An elastic element is installed between the left side of the lower inclined block and the inner wall of the pit. The left end of the sliding rod is in contact with the surface of the rotating rod, and the surface of the rotating rod is in contact with the left side of the push plate. When the mounting plate is opened, the heat-conducting plate will be moved down by the cabinet, which will cause the inner rod to move down in the outer rod. The inner rod will cause the upper inclined block to move down, and the upper inclined block will push the lower inclined block to move to the left through the inclined surface. The lower inclined block will cause the sliding rod to move to the left, and the sliding rod will push the rotating rod to rotate. The rotating rod will push the push plate to move to the right through the lever principle. The push plate will move to the right and further push the water in the pit to the right drainage hole. At the same time, the spring will drive the push plate to move to the left and reset, which can push the excess water to the through hole on the left, so that the water can be discharged from the through hole into the drainage hole. The baffle below the block can block the through hole when the water is not draining, preventing insects below the drainage hole from entering the through hole.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This underground distribution cabinet, through the coordinated operation of the foundation pit, mounting plate, slide rail, support plate, limit plate, threaded rod, cylinder, mounting block, and cabinet body, enables the rapid installation and fixation of the distribution cabinet via the slide rail. When it is necessary to store the distribution cabinet underground or remove it to the ground, the cylinder will be activated and drive the mounting block to move. The mounting block will push the mounting plate to rotate, and the mounting plate will drive the cabinet to rotate and store or move it out of the foundation pit, thus facilitating workers to perform maintenance work on the distribution cabinet.

[0011] 2. This underground distribution cabinet works in coordination with the telescopic rod, support spring, heat-conducting plate, cooling pipe, water pump, and hose. When the mounting plate rotates the cabinet into the pit, the cabinet rotates and contacts the heat-conducting plate, pushing the heat-conducting plate downward and compressing the telescopic rod and the support spring on its surface. At this time, the support spring will lift the heat-conducting plate to support the distribution cabinet, improving the stability of the distribution cabinet after installation. At the same time, the water pump will start and draw rainwater collected in the pit through the hose and introduce it into the cooling pipe. The cooling pipe will cool and dissipate heat from the distribution cabinet body through the heat-conducting plate.

[0012] 3. This underground distribution cabinet operates through the coordinated movement of its outer casing, moving rod, stop block, baffle, drainage hole, rope, inner plate, outer plate, limit rod, and limit groove. When maintenance is required, the mounting plate will rotate and open, causing the support plate to rotate. The support plate will then move the rope upwards, which in turn will move the moving rod upwards. The moving rod will then move the stop block upwards, at which point the stop block will no longer block the drainage hole. Water in the pit will then enter the drainage hole through the outer casing and be discharged, ensuring that all water in the pit is drained. This facilitates subsequent maintenance and repair of the distribution cabinet by personnel entering the pit.

[0013] 4. This underground distribution cabinet operates through the coordinated movement of the outer rod, inner rod, upper inclined block, sliding rod, lower inclined block, rotating rod, push plate, and through hole. When the mounting plate is opened, the heat-conducting plate is moved downward by the cabinet body. The heat-conducting plate moves the inner rod downward within the outer rod, and the inner rod moves the upper inclined block downward. The upper inclined block pushes the lower inclined block to the left through the inclined surface, and the lower inclined block moves the sliding rod to the left. The sliding rod pushes the rotating rod to rotate, and the rotating rod pushes the push plate to the right through the lever principle. The push plate moves to the right and further pushes the water in the pit towards the drainage hole on the right. At the same time, the spring moves the push plate to the left to reset, which can push excess water to the through hole on the left, allowing the water to drain from the through hole into the drainage hole.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-6One embodiment of the present invention is as follows: an underground power distribution cabinet includes a pit 1, a cooling device 4, a drainage device 5, and a flow-pushing device 6; an installation plate 2 is rotatably connected to the inner wall of the pit 1, a slide rail 21 is fixedly connected to the bottom of the installation plate 2, a cabinet body 3 is slidably connected to the surface of the slide rail 21, a support plate 22 is fixedly connected to the right side of the slide rail 21, a limit plate 23 is installed on the left side of the slide rail 21, a threaded rod 24 is threadedly connected to the inner wall of the left side of the slide rail 21, a cylinder 25 is rotatably connected to the inner wall of the pit 1, and an installation block 26 is rotatably connected to the output end of the cylinder 25. When installing the power distribution cabinet, the power distribution cabinet is mechanically lifted to the upright slide rail 21, and the cabinet body 3 is inserted into the slide rail 21 under the guidance of the employee, so that the cabinet body 3 moves onto the support plate 22. Then, the limit plate 23 is placed on the side of the slide rail 21 away from the support plate 22, and the threaded rod 24 is driven into the slide rail 21. The distribution cabinet is installed in track 21, which allows for quick installation and fixation. Cooling device 4 is installed on the inner wall of pit 1, drainage device 5 is installed on the inner wall of pit 1, and flow propulsion device 6 is installed on the inner wall of pit 1. The top of support plate 22 is fixedly connected to the bottom of mounting plate 2, the left side of support plate 22 is in contact with the right side of cabinet 3, the top of limit plate 23 is in contact with the bottom of mounting plate 2, the right side of limit plate 23 is in contact with the left side of cabinet 3, the inner wall of limit plate 23 is in contact with the surface of threaded rod 24, and the top of mounting block 26 is fixedly connected to the bottom of mounting plate 2. When the distribution cabinet needs to be stored underground or taken out to the ground, cylinder 25 will start and drive mounting block 26 to move. Mounting block 26 will push mounting plate 2 to rotate, and mounting plate 2 will drive cabinet 3 to rotate to store or move out of pit 1, thus facilitating workers to perform maintenance on the distribution cabinet.

[0024] The cooling device 4 includes a telescopic rod 41, a support spring 42, and a heat-conducting plate 43. The telescopic rod 41 is installed on the inner wall of the pit 1. The support spring 42 is sleeved on the surface of the telescopic rod 41. The heat-conducting plate 43 is fixedly connected to the top of the telescopic rod 41. The two ends of the support spring 42 are fixedly connected to the bottom of the heat-conducting plate 43 and the inner wall of the pit 1, respectively. The top of the heat-conducting plate 43 is in contact with the bottom of the cabinet 3. When the mounting plate 2 drives the cabinet 3 to rotate into the pit 1, the cabinet 3 rotates and contacts the heat-conducting plate 43, pushing the heat-conducting plate 43 downward and compressing the telescopic rod 41 and the support spring 42 on its surface. At this time, the support spring 42 will lift the heat-conducting plate 43 to support the distribution cabinet and improve the stability of the distribution cabinet after installation. The cooling device 4 includes a cooling pipe 431, a water pump 432, and a hose 433. The cooling pipe 431 is installed on the heat-conducting plate 43. The water pump 432 is fixedly connected to the right side of the heat-conducting plate 43, and the hose 433 is fixedly connected to the bottom of the water pump 432. The bottom of the hose 433 is in contact with the inner wall of the pit 1. The output end of the water pump 432 is fixedly connected to the right end of the cooling pipe 431. The water pump 432 will start and draw the rainwater collected in the pit 1 through the hose 433 and pass it into the cooling pipe 431. The cooling pipe 431 will cool down the power distribution cabinet body through the heat-conducting plate 43, thereby improving the heat dissipation effect of the power distribution cabinet underground and preventing the power distribution cabinet from overheating due to lack of ventilation. When there is no water in the pit 1, water can be added manually by workers. Only the lower part of the pit 1 is waterproofed. When the water volume exceeds one-third of the pit 1, water will leak and seep into the surrounding soil to prevent excessive rainwater collection from contacting the power distribution cabinet.

[0025] The working principle is as follows: When installing the distribution cabinet, the cabinet is mechanically lifted to the upright slide rail 21, and the cabinet body 3 is inserted into the slide rail 21 under the guidance of the staff, so that the cabinet body 3 moves onto the support plate 22. Then, the limiting plate 23 is placed on the side of the slide rail 21 away from the support plate 22, and the threaded rod 24 is driven into the slide rail 21, thereby realizing the quick installation and fixation of the distribution cabinet. When it is necessary to store the distribution cabinet underground or take it out to the ground, the cylinder 25 will be activated and drive the mounting block 26 to move. The mounting block 26 will push the mounting plate 2 to rotate, and the mounting plate 2 will drive the cabinet body 3 to rotate to store or move it out of the pit 1, thus facilitating the maintenance of the distribution cabinet by the workers.

[0026] When the mounting plate 2 rotates the cabinet 3 into the pit 1, the cabinet 3 rotates and contacts the heat-conducting plate 43, pushing the heat-conducting plate 43 downward and compressing the telescopic rod 41 and its surface support spring 42. At this time, the support spring 42 will lift the heat-conducting plate 43 to support the distribution cabinet, improving the stability of the distribution cabinet after installation. At the same time, the water pump 432 will start and draw the rainwater collected in the pit 1 through the hose 433 and pass it into the cooling pipe 431. The cooling pipe 431 will cool and dissipate heat on the distribution cabinet body through the heat-conducting plate 43, thereby improving the heat dissipation effect of the distribution cabinet underground and preventing the distribution cabinet from overheating due to lack of ventilation. When there is no water in the pit 1, water can be added manually by workers. Only the lower part of the pit 1 is treated to prevent water leakage. When the water volume exceeds one-third of the pit 1, water will leak and seep into the surrounding soil to prevent excessive rainwater collection from contacting the distribution cabinet.

[0027] Please see Figure 5-7Based on the above embodiments, in another embodiment of the present invention, the drainage device 5 includes a housing 51, a movable rod 52, a stop block 53, a baffle plate 54, a drainage hole 55, and a rope 56. The housing 51 is fixedly connected to the inner wall of the pit 1, the movable rod 52 is slidably connected to the inner wall of the housing 51 by a spring, the stop block 53 is fixedly connected to the bottom end of the movable rod 52, the baffle plate 54 is fixedly connected to the bottom of the stop block 53, the drainage hole 55 is opened at the bottom of the pit 1, and the rope 56 is fixedly connected to the top of the movable rod 52. During maintenance, the mounting plate 2 will rotate and open, causing the support plate 22 to rotate. The support plate 22 will then move the rope 56 upward, which in turn will move the moving rod 52 upward. The moving rod 52 will then move the stop block 53 upward. At this point, the stop block 53 will no longer block the drain hole 55, and the water in the pit 1 will enter the drain hole 55 through the outer casing 51 and be discharged, ensuring that all the water in the pit 1 is drained. This facilitates subsequent maintenance and repair of the distribution cabinet by personnel entering the pit 1. The drainage device 5 also includes an inner plate 561, an outer plate 562, and a limit switch. The rod 563 and the limiting groove 564 are connected together. The outer plate 562 is slidably connected to the inner wall of the pit 1. The inner plate 561 is slidably connected to the inner wall of the top of the outer plate 562 by a spring. The limiting rod 563 is fixedly connected to the front and rear sides of the inner plate 561. The limiting groove 564 is opened in the inner wall of the pit 1. The surface of the limiting rod 563 is in contact with the inner wall of the limiting groove 564. The top of the inner plate 561 is slidably connected to the bottom of the heat-conducting plate 43. The surfaces of the stop block 53 and the baffle 54 are in contact with the inner wall of the drainage hole 55. The top of the rope 56 is connected to the inner wall of the drainage hole 55. The surface of the support plate 22 is fixedly connected. When the mounting plate 2 rotates, it will drive the heat-conducting plate 43 to move down through the cabinet 3. The heat-conducting plate 43 will drive the inner plate 561 to move down in the outer plate 562. At the same time, the limiting rod 563 on the inner plate 561 is in the limiting groove 564. Therefore, the limiting groove 564 will also guide the limiting rod 563, so that the limiting rod 563 and the inner plate 561 move down and move to the right at the same time. The inner plate 561 will drive the outer plate 562 to move. The outer plate 562 will push the water in the pit 1 to the drainage hole 55, thereby improving the drainage efficiency.

[0028] The telescopic rod 41 mainly consists of an outer rod 61 and an inner rod 62. The outer rod 61 is fixedly connected to the inner wall of the pit 1, and the inner rod 62 is slidably connected to the inner wall of the outer rod 61. An upper inclined block 63 is fixedly connected to the bottom of the inner rod 62, and the surface of the inner rod 62 is slidably connected to the inner wall of the pit 1. The top of the inner rod 62 is fixedly connected to the bottom of the heat-conducting plate 43, and the surface of the upper inclined block 63 is slidably connected to the inner wall of the pit 1. The flow-pushing device 6 includes a sliding rod 631, a lower inclined block 632, a rotating rod 633, and a push plate 6. 34 and through hole 635, slide rod 631 is slidably connected to the inner wall of pit 1, lower inclined block 632 is fixedly connected to the right end of slide rod 631, rotating rod 633 is rotatably connected to the inner wall of pit 1 through torsion spring, push plate 634 is slidably connected to the inner wall of pit 1 through spring, through hole 635 is opened in the inner wall of pit 1. When mounting plate 2 is opened, heat conduction plate 43 will be driven down by cabinet 3, heat conduction plate 43 will drive inner rod 62 down in outer rod 61, inner rod 62 will drive upper inclined block 63 down. The upper inclined block 63 pushes the lower inclined block 632 to the left via the inclined surface. The lower inclined block 632 drives the sliding rod 631 to the left, and the sliding rod 631 drives the rotating rod 633 to rotate. The rotating rod 633 pushes the push plate 634 to the right through the lever principle. The push plate 634 moves to the right and further pushes the water in the pit 1 to the right drainage hole 55. At the same time, the spring drives the push plate 634 to move to the left and reset, which can push the excess water to the through hole 635 on the left, so that the water can be discharged from the through hole 635 to the drainage hole 5. In section 5; the through hole 635 is connected to the drainage hole 55, the lower surface of the upper inclined block 63 is in contact with the upper surface of the lower inclined block 632, an elastic element is provided between the left side of the lower inclined block 632 and the inner wall of the pit 1, the left end of the sliding rod 631 is in contact with the surface of the rotating rod 633, the surface of the rotating rod 633 is in contact with the left side of the push plate 634, and the baffle 54 below the stop block 53 can block the through hole 635 without drainage, preventing insects below the drainage hole 55 from entering the through hole 635.

[0029] Working principle: When maintenance is required, the mounting plate 2 rotates and opens, causing the support plate 22 to rotate. The support plate 22 then moves the rope 56 upward, which in turn moves the moving rod 52 upward. The moving rod 52 then moves the stop block 53 upward. At this point, the stop block 53 will no longer block the drain hole 55, allowing water in the pit 1 to flow through the outer casing 51 into the drain hole 55 and be discharged. This ensures that all water in the pit 1 is drained, facilitating subsequent maintenance and repair of the distribution cabinet by personnel entering the pit 1. When the mounting plate 2 rotates, it will drive the heat-conducting plate 43 to move downward through the cabinet 3. The heat-conducting plate 43 will drive the inner plate 561 to move downward within the outer plate 562. At the same time, the limiting rod 563 on the inner plate 561 is in the limiting groove 564. Therefore, the limiting groove 564 will also guide the limiting rod 563, so that the limiting rod 563 and the inner plate 561 move downward and to the right at the same time. The inner plate 561 will drive the outer plate 562 to move. The outer plate 562 will push the water in the pit 1 towards the drainage hole 55, thereby improving the drainage efficiency.

[0030] When the mounting plate 2 is opened, the heat-conducting plate 43 will be moved down by the cabinet 3. The heat-conducting plate 43 will move the inner rod 62 down in the outer rod 61. The inner rod 62 will move the upper inclined block 63 down. The upper inclined block 63 will push the lower inclined block 632 to the left through the inclined surface. The lower inclined block 632 will move the sliding rod 631 to the left. The sliding rod 631 will push the rotating rod 633 to rotate. The rotating rod 633 will push the push plate 634 to the right through the lever principle. The push plate 634 will move to the right and further push the water in the pit 1 to the right drain hole 55. At the same time, the spring will drive the push plate 634 to the left to reset. This can push the excess water to the left through hole 635, so that the water can be discharged from the through hole 635 into the drain hole 55. The baffle 54 below the baffle 53 can block the through hole 635 without draining water, preventing insects below the drain hole 55 from entering the through hole 635.
