A rainproof intelligent ring main unit

Abstract

This invention discloses a rainproof intelligent ring main unit, relating to the field of ring main unit technology. The ring main unit includes a base, a cabinet body fixed to the top of the base, ventilation holes on the side walls of the cabinet body, a control module fixed to the front of the cabinet body, and a cavity on the top of the cabinet body. In heavy rain, the amount of rainwater entering the water tank through the opening on the top of the cabinet body is greater than the drainage volume of the connecting pipe, causing a large accumulation of rainwater in the tank. Due to its weight, the water moves downwards, squeezing a pressure sensor. The control module then starts a motor, causing a rotating shaft to drive a dispersing block, which disperses the rainwater falling on the top of the cabinet body, allowing it to spread outwards. This solves the problem of large amounts of rainwater falling on the cabinet body easily entering the cabinet through gaps and causing damage to electrical equipment.

Summary of the Invention

The rotating rod passes through the turntable and is fixedly connected at the point of penetration. The rotating block is fixed to the outer wall of the rotating rod. The friction wheel is fixed to the outer wall of the rotating rod. The outer wall of the friction wheel is in contact with the inner wall of the friction ring. When the rotating shaft rotates, it can drive the rotating rod on the rotating shaft to rotate, thereby causing the friction wheel to rotate in contact with the inner wall of the friction ring. This allows the friction wheel to rotate due to friction, and the rotating rod can drive the rotating block to rotate.

[0010] Preferably, the bending block passes through the disassembly block and is slidably connected at the point of penetration. One side of the return spring is fixed to the inner wall of the disassembly block, and the other side of the return spring is fixed to the outer wall of the bending block. The moving block is slidably installed on the inner wall of the bending block. The triangular block is fixed to the outer wall of the moving block. The squeegee is fixed to the bottom of the moving block, and the bottom of the squeegee is in contact with the top of the cabinet. The square frame is fixed to the bottom of the disassembly block.

[0013] Preferably, the actuating device includes a push block, an inclined block, a connecting rod, an auxiliary spring, a ring, an L-shaped pressure block, a guide plate, a spring sheet, a connecting block, and a scraper.

When the bending block moves, the push block will press against the inclined surface of the inclined block, so that the inclined block can move upward under the pressure. When the inclined block moves upward, it will drive the connecting rod and the ring to move upward.

[0015] This invention provides a rainproof intelligent ring main unit. It has the following advantages:

[0016] 1. This ring main unit incorporates a diffusion device. During heavy rain, the amount of rainwater entering the storage tank through the opening at the top of the unit exceeds the drainage capacity of the connecting pipes, causing a large accumulation of rainwater in the tank. The weight of the tank causes it to move downwards, compressing the pressure sensor. The control module then activates a motor, causing the rotating shaft to drive a dispersing block, which disperses the rainwater falling onto the top of the unit, preventing it from easily entering the unit through gaps and damaging electrical equipment. Furthermore, when rainwater enters the storage tank, it is drained through the connecting pipes into a connecting cover, which then flows into the cooling pipes, effectively cooling the unit. This addresses the issue of high humidity and poor heat dissipation during heavy rain, which can cause the internal temperature to rise faster than on sunny days, leading to overheating and damage to electrical equipment.

[0017] 2. This ring main unit incorporates an auxiliary device. When the rotating shaft rotates, it drives the disintegrating block to rotate, causing the friction wheel on the rotating rod to rotate on the inner wall of the friction ring. Due to friction, the friction wheel rotates, causing the rotating block to rotate. This rotating block then compresses and bends the moving block, moving it and allowing the scraper to push rainwater from the center of the unit towards the edge, where it is drained away. This solves the problem of rainwater accumulating at a single point on the top of the ring main unit, forming a high-pressure area, and reduces the pressure on the ring main unit. The pressure at the sealing strip or seam extends the life of the sealant; and by setting a fixed plate, L-shaped fixed block, limit block, return spring, connecting spring, square frame and triangular block, the wiper blade can be made to fit against the top of the cabinet when it moves out of the cabinet. When the wiper blade returns to the middle of the cabinet, it will move upward away from the top of the cabinet, thus solving the problem of rainwater being brought back to the middle of the cabinet when the wiper blade returns to the middle of the cabinet, causing water to accumulate in the middle of the top of the cabinet.

[0018] 3. In this ring main unit's actuation device, when the bending block moves the scraper blade out of the cabinet, the push block presses against the inclined surface of the inclined block, causing the inclined block to move upward under the pressure. This stretches the auxiliary spring, and the inclined block moves the connecting rod upward. Through the cooperation of the ring, the L-shaped pressure block presses against the bottom of the guide plate, causing the guide plate to move upward and deforming the spring. When the bending block moves the scraper blade back to its original position, the push block stops pressing against the inclined block. Through the cooperation of the auxiliary spring, the L-shaped pressure block... The pressure block does not compress the bottom of the guide plate. The spring plate allows the guide plate to rotate downwards and reset. By moving the guide plate, when rainwater flows onto the top of the cabinet, the upward movement of the guide plate can push the rainwater further away, preventing a large amount of rainwater from flowing onto the outer wall of the cabinet. Furthermore, when the inclined block moves upwards, the connecting block can drive the scraper to scrape away the rainwater on the outer wall of the broken block. This solves the problem that when a water film forms on the surface of the broken block, the energy dissipates upon collision with the water flow, and the efficiency of breaking and throwing away the rainwater drops sharply.

Detailed Implementation

[0029] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-9 One embodiment of the present invention is: a rainproof intelligent ring network cabinet, including a base 1, a cabinet 2 fixed on the top of the base 1, heat dissipation holes 3 on the side wall of the cabinet 2, heat dissipation of electrical equipment inside the cabinet 2 through the heat dissipation holes 3, a control module 4 fixed on the front of the cabinet 2, a cavity 8 opened on the top of the cabinet 2, and a diffusion device for dispersing rainwater on the top of the cabinet 2.

[0031] The diffusion device includes a water tank 51, a support spring 52, a pressure sensor 53, a motor 54, a rotating shaft 55, a dispersing block 56, a connecting pipe 57, a connecting cover 58, and a cooling pipe 59. The water tank 51 is slidably installed on the inner wall of the cavity 8. The bottom of the support spring 52 is fixed to the inner wall of the cavity 8, and the top of the support spring 52 is fixed to the bottom of the water tank 51. The pressure sensor 53 is fixed to the inner wall of the cavity 8 and is electrically connected to the control module 4. The motor 54 is fixed to the inner wall of the cabinet 2. The output end is fixed with a rotating shaft 55, which passes through the top of the cabinet 2 and is rotatably sealed at the point of penetration. A disintegrating block 56 is fixed on the outer wall of the rotating shaft 55. The control module 4 is electrically connected to the motor 54. The connecting pipe 57 is fixed at the bottom of the water tank 51. The connecting cover 58 is fixed on the inner wall of the cabinet 2. The end of the connecting pipe 57 is fixedly connected to the side wall of the connecting cover 58. The connecting pipe 57 is a flexible hose and is connected to the connecting cover 58. The cooling pipe 59 is fixed at the bottom of the connecting cover 58 and passes through the back of the cabinet 2.

[0032] The top of the cabinet 2 has a through hole, so that when it rains heavily, rainwater will enter the water storage tank 51 through the through hole, and the water in the water storage tank 51 will be discharged through the connecting pipe 57.

[0033] When heavy rain occurs, the amount of rainwater entering the water storage tank 51 through the opening at the top of the cabinet 2 is greater than the drainage volume of the connecting pipe 57. This causes a large amount of rainwater to accumulate in the water storage tank 51. Due to its weight, the water storage tank 51 moves downward and squeezes the pressure sensor 53. The control module 4 controls the motor 54 to start, causing the rotating shaft 55 to drive the dispersing block 56 to rotate. This can rotate and disperse the rainwater falling on the top of the cabinet 2, allowing the rainwater to spread in all directions. This solves the problem that a large amount of rainwater falling on the cabinet 2 can easily enter the interior of the cabinet 2 through the gaps, causing damage to electrical equipment.

[0034] Furthermore, when rainwater enters the water storage tank 51, it can be discharged into the connecting cover 58 through the connecting pipe 57, and then enter the cooling pipe 59 through the connecting cover 58, thereby achieving the effect of cooling the inside of the cabinet 2. This solves the problem that during heavy rain, the air humidity is high and the heat dissipation is poor, and the temperature inside the cabinet rises faster than on sunny days, which leads to the electrical equipment inside the equipment being damaged by heat.

[0035] In this embodiment, during operation: when the outdoor ring main unit encounters heavy rain, the amount of rainwater entering the water storage tank 51 through the through-hole at the top of the cabinet 2 is greater than the amount drained by the connecting pipe 57. This causes rainwater to accumulate in the water storage tank 51, and the weight of the rainwater causes the water storage tank 51 to move downwards, compressing the support spring 52. When the water storage tank 51 moves downwards and comes into contact with the pressure sensor 53, the bottom of the water storage tank 51 will squeeze the pressure sensor 53. When the pressure sensor 53 is squeezed, it will emit an electrical signal, which will be transmitted to the control module 4. The control module 4 can then control the motor 54 to start. When the motor 54 starts, it can drive the rotating shaft 55 to rotate, causing the dispersing block 56 to rotate at the top of the cabinet 2 to beat the rainwater. When rainwater enters the water storage tank 51, it will flow through the connecting pipe 57 and the connecting cover 58 into the cooling pipe 59.

[0036] When the rain stops, after the rainwater in the water tank 51 is drained, the support spring 52 is in a compressed state, which will cause the support spring 52 to drive the water tank 51 to move upward and reset, so that the water tank 51 no longer squeezes the pressure sensor 53. When the pressure sensor 53 is no longer squeezed, the electrical signal disappears, and the control module 4 judges that there is "no pressure" and controls the motor 54 to turn off.

[0037] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the top of the cabinet 2 is provided with an auxiliary device to prevent excessive water accumulation on the top of the cabinet 2, and the side wall of the cabinet 2 is provided with a toggle device. The auxiliary device includes a friction ring 61, a turntable 62, a rotating rod 63, a friction wheel 64, a rotating block 65, a bending block 66, a return spring 67, a connecting spring 612, a moving block 68, a triangular block 611, an L-shaped fixing block 614, a fixing plate 613, a limiting block 615, a pushing spring 616, a square frame 610, and a squeegee 69; the friction ring 61 is fixed. The turntable 62 is fixed on the top of the cabinet 2 and is rotatably mounted on the inner wall of the friction ring 61. The rotating rod 63 passes through the disintegrating block 56 and is rotatably connected at the through point. The rotating rod 63 passes through the turntable 62 and is fixedly connected at the through point. The rotating block 65 is fixed on the outer wall of the rotating rod 63. The friction wheel 64 is fixed on the outer wall of the rotating rod 63. The outer wall of the friction wheel 64 is in contact with the inner wall of the friction ring 61. By setting the turntable 62, it is possible to prevent dust and other impurities from entering the friction ring 61 and adhering to the inner wall of the friction ring 61, which would affect the rotation of the friction wheel 64 on the friction ring 61. The bending block 66 passes through the disintegrating block 56 and is slidably connected at the point of penetration. One side of the return spring 67 is fixed to the inner wall of the disintegrating block 56, and the other side of the return spring 67 is fixed to the outer wall of the bending block 66. The moving block 68 is slidably installed on the inner wall of the bending block 66. The triangular block 611 is fixed to the outer wall of the moving block 68. The scraper 69 is fixed to the bottom of the moving block 68, and the bottom of the scraper 69 is in contact with the top of the cabinet 2. The square frame 610 is fixed to the bottom of the disintegrating block 56. The limiting block 615 is slidably installed on the inner wall of the moving block 68. One side of the connecting spring 612 is fixed to the side wall of the limiting block 615, and the other side of the connecting spring 612 is fixed to the inner wall of the moving block 68. The fixing plate 613 is fixed to the outer wall of the bending block 66, and the L-shaped fixing block 614 is fixed to the bottom of the disintegrating block 56.

[0038] When the rotating shaft 55 rotates, it drives the dispersing block 56 to rotate, which causes the friction wheel 64 on the rotating rod 63 to rotate on the inner wall of the friction ring 61. Because the friction wheel 64 is subjected to friction, it can rotate on its own, which causes the rotating block 65 to rotate. The rotating block 65 can squeeze the bending block 66 and drive the moving block 68 to move, so that the scraper 69 can push the rainwater in the middle of the cabinet 2 to the edge of the cabinet 2 and drain it away from the edge of the cabinet 2. This solves the problem of rainwater accumulating at a certain point on the top of the ring main unit and forming a high-voltage area.

[0039] This reduces pressure on the sealing strips or joints, extending the life of the seals. Furthermore, by using a combination of a fixing plate 613, an L-shaped fixing block 614, a limiting block 615, a return spring 67, a connecting spring 612, a square frame 610, and a triangular block 611, the wiper blade 69 can adhere to the top of the cabinet 2 when moving outwards. When the wiper blade 69 returns to its original position and moves towards the center of the cabinet 2, it moves upwards away from the top of the cabinet 2. This solves the problem of the wiper blade 69 bringing rainwater from the top of the cabinet 2 back to the center of the cabinet 2 during its return, thus preventing water accumulation in the center of the top of the cabinet 2.

[0040] The side wall of the fixed plate 613 has a slot, and the limiting block 615 extends into the slot to limit the movement of the moving block 68.

[0041] The actuating device includes a push block 71, an inclined block 73, a connecting rod 72, an auxiliary spring 74, a ring 75, an L-shaped pressure block 76, a guide plate 77, a spring plate 78, a connecting block 79, and a scraper 710. The push block 71 is fixed to the top of the bending block 66. The connecting rod 72 passes through the dispersing block 56 and is slidably connected at the point of penetration. The inclined block 73 is fixed to the top of the connecting rod 72. One side of the auxiliary spring 74 is fixed to the bottom of the inclined block 73, and the other side of the auxiliary spring 74 is fixed to the bottom of the inclined block 73. The ring 75 is fixed to the bottom of the connecting rod 72 and the ring 76 is fixed to the top of the disintegrating block 56. The L-shaped pressure block 76 is slidably installed on the outer wall of the cabinet 2. The top outer wall of the L-shaped pressure block 76 is slidably connected to the bottom inner side of the ring 75. One side of the spring plate 78 is fixed to the outer wall of the cabinet 2 and the other side of the spring plate 78 is fixed to the bottom of the guide plate 77. The connecting block 79 is fixed to the outer wall of the inclined block 73 and the scraper 710 is fixed to the side of the connecting block 79 away from the inclined block 73.

[0042] When the bending block 66 moves the scraper 69 outward from the cabinet 2, the push block 71 will press against the inclined surface of the inclined block 73, causing the inclined block 73 to move upward under the pressure. This stretches the auxiliary spring 74 and causes the inclined block 73 to move the connecting rod 72 upward. Through the cooperation of the ring 75, the L-shaped pressure block 76 will press against the bottom of the guide plate 77, causing the guide plate 77 to move upward and deforming the spring plate 78. When the bending block 66 moves the scraper... When the water plate 69 is reset, the push block 71 will not press the inclined block 73. With the cooperation of the auxiliary spring 74, the L-shaped pressure block 76 will not press the bottom of the guide plate 77. The spring plate 78 will allow the guide plate 77 to rotate downwards to reset. When the guide plate 77 is pushed, when rainwater from the top of the cabinet 2 flows onto the guide plate 77, the guide plate 77 will be pushed upwards to push the rainwater further away, preventing a large amount of rainwater from flowing onto the outer wall of the cabinet 2.

[0043] Furthermore, when the inclined block 73 moves upward, the connecting block 79 can drive the scraper 710 to scrape away the rainwater on the outer wall of the broken block 56, thus solving the problem that the surface of the broken block 56 is covered with a layer of water film, and the energy of its collision with the water flow is dissipated, resulting in a sharp drop in the efficiency of breaking and throwing away the rainwater.

[0044] In this embodiment, when the disintegrating block 56 rotates, it drives the rotating rod 63 to rotate, causing the friction wheel 64 on the rotating rod 63 to move in a circular motion against the inner wall of the friction ring 61. The friction wheel 64 rotates due to friction, driving the rotating rod 63 to rotate. When the rotating rod 63 rotates on the disintegrating block 56, it drives the rotating block 65 to rotate. When the rotating block 65 rotates to the point where it presses against the bending block 66, the rotating block 65 pushes the bending block 66 away from the rotating shaft 55, thereby... The bending block 66 is moved away from the pivot 55, compressing the return spring 67. As the bending block 66 moves, it also moves the moving block 68 and the scraper 69, causing the scraper 69 to adhere to the top of the cabinet 2 away from the pivot 55. When the bending block 66 moves the moving block 68 to a position where the inclined surface of the triangular block 611 contacts the side wall of the square frame 610, the movement of the bending block 66 causes the triangular block 611 to move upwards under pressure, compressing the connecting spring 612. This allows the movable block 68 and the scraper 69 to move upwards away from the top of the cabinet 2. When the movable block 68 moves upwards and aligns with the slot on the fixed plate 613, the push spring 616 is compressed, causing the limit block 615 to extend into the slot, thus limiting the movable block 68. When the rotating block 65 rotates to a point where it no longer presses against the bending block 66, the return spring 67 is compressed, allowing it to move... The bending block 66 is reset so that the squeegee 69 does not contact the top of the cabinet 2 during the reset. When the bending block 66 moves to the L-shaped fixing block 614, the L-shaped fixing block 614 will press the limiting block 615 out of the slot in the fixing plate 613. Since the connecting spring 612 is in a compressed state, the connecting spring 612 can drive the moving block 68 and the squeegee 69 to move downward to reset. At this time, the squeegee 69 will once again fit against the top of the cabinet 2 for the next squeegee operation.

[0045] When the bending block 66 moves away from the rotating shaft 55, the push block 71 will press against the inclined surface of the inclined block 73. Due to the pressure, the inclined block 73 can move upward, causing the connecting rod 72 to move upward and the auxiliary spring 74 to stretch and deform. When the connecting rod 72 moves upward, it can move the ring 75. At the same time as the ring 75 moves upward, the inner side of the ring 75 can move the L-shaped pressure block 76 upward, which will cause the L-shaped pressure block 76 to press against the bottom of the guide plate 77, causing the guide plate 77 to move upward and the spring plate 78 to deform. When the bending block 66 moves the push block 71 towards the rotating shaft 55, it will cause the push block 71 to move upward. When the inclined surface of the inclined block 73 is pressed, the auxiliary spring 74 is in a stretched state, which can cause the auxiliary spring 74 to drive the inclined block 73 to move downward to reset. When the connecting rod 72 moves downward, it can drive the ring 75 and the L-shaped pressure block 76 to move downward to reset, so that the L-shaped pressure block 76 does not press the bottom of the guide plate 77. When the spring plate 78 is in a deformed state, it can drive the guide plate 77 to rotate downward to reset. When the inclined block 73 moves upward, it can drive the scraper 710 to move upward through the connecting block 79 to scrape away the water droplets on the outer wall of the scattered block 56. When the inclined block 73 moves downward, it can drive the scraper 710 to move downward to reset through the connecting block 79.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
