Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and particularly relates to a high and low voltage power switch cabinet. Background Art

[0002] High and low voltage power switch cabinets control the on-off of power circuits through various switching electrical appliances such as circuit breakers and load switches to meet the operating requirements of different equipment and lines. They are configured with overcurrent protection, overvoltage protection, undervoltage protection, leakage protection and other devices. When a fault occurs in the power system, the circuit is quickly cut off to protect the safety of equipment and personnel. Ammeters, voltmeters, wattmeters, watt-hour meters and other instruments are installed, and they are usually installed indoors or outdoors.

[0003] For switch cabinets installed outdoors, in order to cool the interior of the cabinet, heat dissipation openings are usually provided on the side walls of the cabinet, and heat dissipation nets are installed inside the heat dissipation openings to dissipate heat from the interior of the cabinet. Through the setting of the heat dissipation nets, sundries outside the cabinet can be intercepted from entering, and the cooling effect can also be achieved. However, during the long-term heat dissipation process, the heat dissipation nets are prone to being contaminated with dust, spider web impurities, etc., resulting in a deterioration of the cabinet cooling effect. Personnel need to manually clean the heat dissipation nets, which requires the removal of the heat dissipation nets for cleaning, exposing the heat dissipation opening positions, causing external sundries to enter the cabinet from the heat dissipation openings, and the cleaning efficiency of removing the heat dissipation nets is low.

[0004] Based on this, a high and low voltage power switch cabinet is proposed here to solve the above problems. Summary of the Invention

The other end of the guide pipe is fixedly connected and communicated with the inside of the sealing airbag. A limiting plate located on the sliding rod is fixed inside the cabinet.

[0013] Preferably, the adjusting mechanism includes a motor, which is fixed on the upper end of the protection plate. The output shaft at the lower end of the motor is fixed with a vertically arranged reciprocating lead screw, and the bottom end of the reciprocating lead screw is rotatably connected to the bottom end inside the protection plate.

A vertically arranged guide rail is fixed inside the protection plate, and the guide rail is in a rectangular square structure.

[0014] Preferably, the cleaning mechanism further includes a water pump, which is fixed on the upper end of the water storage tank. One end of the water inlet pipe is fixedly connected to the water outlet of the water pump. The water inlet of the water pump is fixed with a water suction pipe extending into the bottom end inside the water storage tank.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, water is sprayed out by the nozzle and sprayed onto the heat dissipation nets on both sides of the protection plate to clean the heat dissipation nets. During the cleaning process, the support seat moves up and down to drive the nozzle to move and wash different parts of the heat dissipation nets. During the movement of the support seat, the hose moves, bends and unfolds together to adapt to the movement of the nozzle. A counterweight is added to the bent part of the hose so that the hose can bend better when the support seat moves up. In this way, the collected rainwater can be used for cleaning without disassembling the heat dissipation nets, which is convenient and time-saving. The collected rainwater is used locally without the need to connect an external water pipe separately, and the cleaning efficiency is high. During the water spraying process of the nozzle, the sealing mechanism blocks the heat dissipation port to prevent water from entering the cabinet body and affecting the operation of internal components.

[0020] 2. The sealing plate and the sealing airbag move up until they block the heat dissipation port to prevent water from entering the cabinet body. During the upward movement of the sealing plate, the air storage tank is driven to move up until the top end of the sliding rod contacts the lower end of the limiting plate, causing the sliding rod to move down inside the air storage tank, and the sealing sliding plate to slide down inside the air storage tank to compress the spring. The gas stored inside the air storage tank is pushed into the sealing airbag through the air guide pipe, making the sealing airbag more inflated to seal the heat dissipation port, further sealing the heat dissipation port to prevent water from entering the cabinet body and preventing sundries from entering the cabinet body. Moreover, when the sealing plate blocks the heat dissipation port, during the process of the nozzle spraying water to clean the heat dissipation nets, the heat of the heat-absorbing sealing plate is absorbed, enabling the heat of the cabinet body to be exchanged with the sealing plate, and the heat of the sealing plate to be further exchanged with the water sprayed by the nozzle, thereby cooling the cabinet body.

[0021] 3. When the heat dissipation nets are washed by the nozzle spraying water, the water flowing from the water inlet pipe flows into the heat absorption pipe, then flows into the drain pipe from the lower end, and finally flows into the water storage tank. During the flow of water in the heat absorption pipe, the heat between the protection plate and the sealing plate is taken away. When cleaning the heat dissipation nets, heat can still be quickly taken away during the sealing of the heat dissipation port, providing a cooling effect for the cabinet body. Moreover, during the up and down movement of the support seat, the rotating shaft is driven to move, causing the gear to rotate along the direction of the rack, so that the rotating shaft and the fan blades rotate during the up and down movement between the protection plate and the sealing plate, stirring the air flow inside the protection plate, cooperating with the water flowing inside the heat absorption pipe and the water sprayed by the nozzle, to more quickly take away the heat between the protection plate and the sealing plate, cooling the cabinet body. In addition, the gear and the limiting block limit the support seat, enabling the support seat to move up and down when the reciprocating lead screw rotates, driving the nozzle to move and wash the heat dissipation nets.

Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 9 As shown in the figure, a high and low voltage switch cabinet for electricity includes a cabinet body 1 and a heat dissipation port 101 opened on the side wall of the cabinet body 1. A protection plate 2 is fixed on the side wall of the cabinet body 1 near the heat dissipation port 101. The protection plate 2 has a U-shaped structure, and heat dissipation nets 21 are fixed on both sides of the protection plate 2;

[0036] A cleaning mechanism 4 is installed inside the protection plate 2. The cleaning mechanism 4 includes a support seat 48 that moves up and down inside the protection plate 2. A vertical pipe 47 is fixed to the support seat 48. The bottom end of the vertical pipe 47 is fixedly connected through and has a horizontal pipe 45. Nozzles 44 facing the heat dissipation net 21 are fixed to both ends of the horizontal pipe 45 and are communicated therewith. An L-shaped hose 46 is fixed to the upper end of the vertical pipe 47. The upper end of the hose 46 is fixed with a water inlet pipe 41 that penetrates the upper end of the protection plate 2. A water storage tank 43 with an open upper end is fixed to the side wall of the cabinet body 1. The cleaning mechanism 4 further includes a water pump 42. The water pump 42 is fixed to the upper end of the water storage tank 43. One end of the water inlet pipe 41 is fixedly connected to the water outlet of the water pump 42. A water suction pipe 4101 that extends into the bottom end inside the water storage tank 43 is fixed to the water inlet of the water pump 42. A hanging ring 49 is sleeved on the bent part at the bottom end of the hose 46. A counterweight 410 is rotatably connected to the bottom end of the hanging ring 49. By installing the protection plate 2 on one side of the heat dissipation port 101 and fixing the heat dissipation nets 21 on both sides of the protection plate 2 for heat dissipation inside the cabinet body 1, the heat dissipation nets 21 are not directly installed inside the heat dissipation port 101, which facilitates the cleaning of the heat dissipation nets 21. When the heat dissipation nets 21 need to be cleaned, the heat dissipation port 101 is sealed by moving up the sealing mechanism 7. At this time, the personnel can control the water pump 42 to be powered on and work, pumping the rainwater stored in the water storage tank 43 into the water inlet pipe 41 through the water suction pipe 4101, then sending it into the hose 46, then into the vertical pipe 47, and then spraying out from the nozzles 44 at both ends of the horizontal pipe 45, spraying onto the heat dissipation nets 21 on both sides of the protection plate 2 to clean the heat dissipation nets 21. During the cleaning process, by moving the support seat 48 up and down, the nozzles 44 are driven to move to clean different parts of the heat dissipation nets 21. During the movement of the support seat 48, the hose 46 moves and bends and unfolds together to adapt to the movement of the nozzles 44. A counterweight 410 is added to the bent part of the hose 46 so that the hose 46 can bend better during the upward movement of the support seat 48. In this way, the heat dissipation nets 21 can be cleaned using the collected rainwater without disassembling them, which is convenient and time-saving, uses the collected rainwater locally, does not require a separate external water pipe, and has a high cleaning efficiency. During the spraying process of the nozzles 44, the sealing mechanism 7 blocks the heat dissipation port 101 to prevent water from entering the cabinet body 1 and affecting the operation of the internal components;

[0037] The protection plate 2 is provided with an adjusting mechanism 3, and the adjusting mechanism 3 is connected to the support seat 48;

[0038] A sealing mechanism 7 for opening and sealing the heat dissipation port 101 is installed inside the cabinet body 1;

[0039] The water inlet pipe 41 is connected with a cooling mechanism 6 for blowing air and dissipating heat inside the protection plate 2.

[0040] In this embodiment, in order to prevent water from entering the cabinet body 1 from the heat dissipation port 101 during the flushing and cleaning process of the heat dissipation nets 21, refer to Figure 1 、 Figure 9, the sealing mechanism 7 includes an electric push rod two 72. The electric push rod two 72 is fixed inside the cabinet body 1. The upper end of the electric push rod is fixed with a sealing plate 71. The sealing plate 71 moves up and down along the inner side of the cabinet body 1. The outer side of the sealing plate 71 is fixed with a sealing airbag 73 with an O-shaped structure. The upper end of the sealing airbag 73 contacts the bottom end of the heat dissipation port 101. The sealing mechanism 7 further includes an air storage tank 75. The air storage tank 75 is fixedly connected to the upper side wall of the sealing plate 71. A sliding rod 76 is vertically slidably connected to the upper end of the air storage tank 75. The bottom end of the sliding rod 76 is fixed with a sealing sliding plate 77. The sealing sliding plate 77 is vertically slidably connected to the inside of the air storage tank 75. A spring 78 is fixed between the bottom end of the sealing sliding plate 77 and the inner wall of the air storage tank 75. The bottom end of the inner wall of the air storage tank 75 is fixed with a guide air pipe 74 with an arc-shaped structure. The other end of the guide air pipe 74 is fixedly connected and communicated with the inside of the sealing airbag 73. A limiting plate 79 located on the sliding rod 76 is fixed inside the cabinet body 1; when cleaning the heat dissipation net 21 by spraying water through the nozzle 44, the electric push rod two 72 can be started to work and extend, pushing up the sealing plate 71 and the sealing airbag 73 until the heat dissipation port 101 is blocked, preventing water from entering the inside of the cabinet body 1. During the upward movement of the sealing plate 71, the air storage tank 75 is driven to move upward until the top end of the sliding rod 76 contacts the lower end of the limiting plate 79, causing the sliding rod 76 to move downward inside the air storage tank 75, and the sealing sliding plate 77 to slide downward inside the air storage tank 75 to compress the spring 78, pushing the gas stored inside the air storage tank 75 into the inside of the sealing airbag 73 through the guide air pipe 74, making the sealing airbag 73 more inflated to seal the heat dissipation port 101, further sealing the heat dissipation port 101, preventing water from entering the inside of the cabinet body 1, preventing sundries from entering the cabinet body 1, and when the sealing plate 71 blocks the position of the heat dissipation port 101, during the process of the nozzle 44 spraying water to clean the heat dissipation net 21, absorbing the heat of the sealing plate 71, enabling the heat of the cabinet body 1 to exchange with the sealing plate 71, and the heat of the sealing plate 71 to exchange with the water sprayed by the nozzle 44 to cool the cabinet body 1. After the heat dissipation net 21 is cleaned for a period of time, by controlling the electric push rod two 72 to contract, the sealing plate 71 and the sealing airbag 73 can be moved downward to open the heat dissipation port 101 for heat dissipation of the cabinet body 1. Then, under the action of the spring 78, the sealing sliding plate 77 moves upward to reset, and the gas inside the sealing airbag 73 enters the air storage tank 75 from the guide air pipe 74.

[0041] To realize the up and down movement of the support seat 48 and the nozzle 44, please refer to Figure 4 , Figure 5 , Figure 7 , the adjusting mechanism 3 includes a motor 31.

The bottom end of the reciprocating lead screw 32 is rotatably connected to the inner bottom end of the protection plate 2. The reciprocating lead screw 32 is threadedly connected to the support seat 48. A guide rail 33 is vertically fixed inside the protection plate 2. The guide rail 33 has a rectangular O-shaped structure; during operation, by starting the motor 31 to work, driving the reciprocating lead screw 32 to rotate, the up and down movement of the support seat 48 is realized, driving the nozzle 44 to move to wash the heat dissipation net 21.

[0042] Embodiment 2

[0043] In order to cool the interior of the cabinet body 1 while the sealing plate 71 seals the heat dissipation opening 101, the cooling mechanism 6 includes a rotating shaft 64. The rotating shaft 64 is horizontally arranged and rotatably connected to the support seat 48. One end of the rotating shaft 64 is fixed with a fan blade 63 located between the protection plate 2 and the heat dissipation opening 101. The other end of the rotating shaft 64 is fixed with a gear 65. A vertically arranged rack 67 is fixed inside the guide rail 33. The gear 65 is meshed with the rack 67. The rotating shaft 64 is rotatably connected with an L-shaped limiting block 66. One side of the limiting block 66 is vertically slidably connected to the inner side of the guide rail 33 for limiting the downward movement of the support seat 48. The bottom end of the water inlet pipe 41 is fixed with a heat absorption pipe 62 arranged inside the protection plate 2. The lower end of the heat absorption pipe 62 penetrates through the bottom end of the protection plate 2. The lower end of the heat absorption pipe 62 is fixed with a drain pipe 61 extending into the interior of the water storage tank 43. During operation, when the sealing plate 71 moves upward to block the heat dissipation opening 101 and the heat dissipation net 21 is sprayed and washed by the spray head 44, the water flowing from the water inlet pipe 41 flows into the heat absorption pipe 62, then flows into the drain pipe 61 from the lower end, and finally flows into the water storage tank 43. During the flow of water in the heat absorption pipe 62, the heat between the protection plate 2 and the sealing plate 71 is taken away. When cleaning the heat dissipation net 21, heat can still be quickly taken away during the sealing of the heat dissipation opening 101, providing a cooling effect for the cabinet body 1. And during the up and down movement of the support seat 48, the rotating shaft 64 is driven to move, so that the gear 65 rotates along the direction of the rack 67, and the rotating shaft 64 and the fan blade 63 rotate during the up and down movement between the protection plate 2 and the sealing plate 71, stirring the air flow inside the protection plate 2, cooperating with the water flowing inside the heat absorption pipe 62 and the water sprayed by the spray head 44, taking away the heat between the protection plate 2 and the sealing plate 71 more quickly, cooling the cabinet body 1. And the gear 65 and the limiting block 66 limit the support seat 48, so that the support seat 48 moves up and down when the reciprocating lead screw 32 rotates, driving the spray head 44 to move and wash the heat dissipation net 21.

[0044] For filtering rainwater, refer to Figure 6 , the water storage tank 43 is connected with a filtering mechanism 5. The filtering mechanism 5 includes a filter screen 51. The filter screen 51 is vertically slidably connected to the upper end inside the water storage tank 43. The upper end of the filter screen 51 is in a V-shaped structure. A vertically arranged fixing frame 52 is fixed to the back of the cabinet body 1. The bottom end of the fixing frame 52 is vertically slidably connected with a slider 53. The bottom end of the slider 53 is fixedly connected to the upper end of the filter screen 51. An electric push rod 54 is fixed to the bottom end of the fixing frame 52. The telescopic end of the bottom end of the electric push rod 54 is fixedly connected to the upper end of the slider 53. The filter screen 51 is slidably connected to the drain pipe 61. The filter screen 51 is used for filtering rainwater entering the water storage tank 43. By the extension and contraction of the electric push rod during operation, the slider 53 and the filter screen 51 can be driven to move up and down in a small range. Under the action of inertia, the sundries at the upper end of the filter screen 51 are shaken, which is beneficial to the rainwater entering the interior of the water storage tank 43 for storage.

[0045] Working principle: The user installs the cabinet body 1 outdoors. The water storage tank 43 is used to store rainwater. By installing the protection plate 2 on one side of the heat dissipation port 101 and fixing the heat dissipation nets 21 on both sides of the protection plate 2 for heat dissipation inside the cabinet body 1, the heat dissipation nets 21 are not directly installed inside the heat dissipation port 101, which facilitates the cleaning of the heat dissipation nets 21. When it is necessary to clean the heat dissipation nets 21, start the electric push rod two 72 to work and extend, push up the sealing plate 71 and the sealing airbag 73 until the heat dissipation port 101 is blocked. Then start the motor 31 to work, drive the reciprocating lead screw 32 to rotate, make the support base 48 move up and down, drive the rotating shaft 64 to move, make the gear 65 rotate along the direction of the rack 67, and make the rotating shaft 64 and the fan blade 63 rotate during the up and down movement between the protection plate 2 and the sealing plate 71, stirring the air flow inside the protection plate 2 for heat dissipation. Then control the water pump 42 to be powered on to work, pump the rainwater stored in the water storage tank 43 into the suction pipe 4101, then send it into the hose 46 through the water inlet pipe 41, then enter the vertical pipe 47, and finally spray out from the nozzles 44 at both ends of the horizontal pipe 45, spraying onto the heat dissipation nets 21 on both sides of the protection plate 2 to clean the heat dissipation nets 21. During the cleaning process, by moving the support base 48 up and down, drive the nozzle 44 to move to wash and clean different parts of the heat dissipation nets 21, making use of the collected rainwater locally. During the spraying process of the nozzle 44, the sealing plate 71 and the sealing airbag 73 block the heat dissipation port 101 to prevent water from entering the cabinet body 1 and affecting the operation of the internal components. And when the heat dissipation nets 21 are washed by spraying water from the nozzle 44, the water flowing from the water inlet pipe 41 flows into the heat absorption pipe 62, then flows into the drain pipe 61 from the lower end, and finally flows into the water storage tank 43. During the flow of water in the heat absorption pipe 62, the heat between the protection plate 2 and the sealing plate 71 is taken away. When cleaning the heat dissipation nets 21, heat can still be quickly taken away during the sealing process of the heat dissipation port 101, providing a cooling effect for the cabinet body 1, making the water flowing inside the heat absorption pipe 62, the water sprayed from the nozzle 44 and the rotating fan blade 63 cooperate to more quickly take away the heat between the protection plate 2 and the sealing plate 71, making the cabinet body 1 dissipate heat and cool down. And the gear 65 and the limit block 66 limit and support the support base 48, making the support base 48 move up and down when the reciprocating lead screw 32 rotates, driving the nozzle 44 to move to wash the heat dissipation nets 21.
