[0004] When the above-mentioned control cabinet is used outdoors, when it rains heavily, a large amount of rainwater will float onto the side walls of the cabinet, causing the rainwater on the cabinet wall to flow down along the side walls of the cabinet, and the rainwater will flow into the interior of the cabinet through the heat dissipation holes or the door gap between the cabinet and the cabinet door, thereby causing damage to the electrical equipment in the cabinet and affecting its normal use in the future. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an automatic control cabinet for a generator set, which solves the problems raised in the above background technology.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An automatic control cabinet for a generator set, including a cabinet body, heat dissipation holes are provided on the side wall of the cabinet body, a sleeve is fixed on the top of the cabinet body, a support column is slidably installed on the inner wall of the sleeve, a support spring is fixed at the bottom of the support column, the bottom of the support spring is fixed on the inner wall of the sleeve, a top plate is fixed at the top of the support column, a water storage tank is provided inside the top plate, a water inlet hole is provided on the top of the top plate, a drain hole is provided on the outer wall of the top plate, a mounting plate is slidably installed on the inner wall of the cabinet body, an electrical device is detachably installed at the bottom of the mounting plate, the bottom of the electrical device is in contact with the bottom of the inner wall of the cabinet body, a shielding device with good protection effect is provided at the top of the electrical device, a dredging device for preventing the water inlet hole from being blocked is provided on the top of the top plate, and an auxiliary device is provided at the bottom of the top plate; wherein, the shielding device includes a push block, a hinge rod, a fixed block, a rotating rod, a protection plate, a pressing block, a pushing spring, a movable rod, a connecting block and a shielding plate; the push block is slidably installed at the bottom of the top plate, a hinge rod is hinged on the outer wall of the sleeve, one end of the hinge rod away from the sleeve is hinged at the end of the push block, the fixed block is fixed on the side wall of the top plate, the rotating rod passes through the fixed block and is rotatably connected at the passing position, the protection plate is fixed on the outer wall of the rotating rod. When it rains heavily, the amount of rainwater entering the water inlet hole will be larger than the amount of rainwater drained from the drain hole, so the rainwater in the water storage tank will increase, causing the top plate to move downward under gravity, driving the support spring to compress. When the top plate moves downward, it can drive the push block to move downward, so that the hinge rod will squeeze the push block, causing the push block to move to the side away from the support column under the squeezing force, so that the push block can squeeze the protection plate and make the protection plate unfold.

[0007] According to the above technical solution, a torsion spring is fixed at the protruding point of the end of the rotating rod, and the side wall of the torsion spring is fixed on the side wall of the protection plate. When the protection plate rotates, it can drive the torsion spring to be compressed and deformed.

[0008] According to the above technical solution, the pressing block is slidably installed on the top of the cabinet body, one side of the pushing spring is fixed inside the top of the cabinet body, the other side of the pushing spring is fixed on the side wall of the pressing block, the shielding plate is slidably installed on the outer wall of the cabinet body, the connecting block is fixed on the outer wall of the pressing block, one end of the movable rod is hinged on the outer wall of the shielding plate, and the other end of the movable rod is hinged at the end of the connecting block. When the protection plate unfolds at the bottom of the top plate, the protection plate will not squeeze the pressing block. Since the pushing spring is in a compressed state, the pushing spring will push the pressing block out of the top of the top plate, causing the pressing block to drive the connecting block to move and squeeze the movable rod, so that the movable rod rotates at the hinge, and then it can push the shielding plate to move into the gap between the cabinet body and the cabinet door to block, preventing rainwater from entering the cabinet through the door seal.

[0009] According to the above technical solution, the dredging device includes an L-shaped connecting block, a rotating shaft, a gear, a rack, a scraper, an inclined block, a connecting rod, a return spring, a connecting seat, a fixed seat and a dredging plate; the L-shaped connecting block is fixed on the outer wall of the pushing block, and the rack is fixed on the side of the L-shaped connecting block away from the pushing block.

[0010] According to the above technical solution, the rotating shaft is rotatably installed on the top of the top plate, the scraper is fixed on the outer wall of the rotating shaft, the gear is fixed on the outer wall of the rotating shaft, the outside of the gear meshes with the rack. When the pushing block moves, it can drive the L-shaped connecting block to move, so that the rack moves on the gear, driving the gear to rotate, and the rotating shaft drives the scraper to rotate.

[0011] According to the above technical solution, the connecting rod penetrates through the top of the top plate and is slidably connected at the penetration. The inclined block is fixed on the top of the connecting rod, the connecting seat is fixed on the bottom of the connecting rod, one side of the return spring is fixed on the inner wall of the water storage tank, the other side of the return spring is fixed on the top of the connecting seat, the fixed seat is fixed on the side wall of the connecting seat, and the dredging plate is fixed on the top of the fixed seat. When the scraper rotates to contact the inclined surface of the inclined block, the scraper will squeeze the inclined block to move upward, driving the connecting rod to move upward, so that the connecting seat drives the fixed seat to move upward, and the water inlet hole is dredged by the dredging piece.

[0012] According to the above technical solution, the auxiliary device includes a bent stop block, a guide rod, a return spring, a pressing plate, a moving seat, a connecting spring, a transmission spring, a pressing rod, a fixed rod and a mounting seat; the bent stop block penetrates through the side wall of the cabinet body and is slidably connected at the penetration. The guide rod is fixed on the inner side of the bent stop block and penetrates through the back of the cabinet body and is slidably connected at the penetration. One side of the return spring is fixed on the outer wall of the bent stop block, and the other side of the return spring is fixed on the outer wall of the cabinet body. The top of the mounting plate is fixedly connected to the bottom of the lifting spring, and the top of the lifting spring is fixed on the inner wall of the cabinet body. When the protruding part at the top of the scraper rotates to contact the bent stop block, the protruding part at the top of the scraper will squeeze the bent stop block to move, so that the limit on the mounting plate can be released. Since the lifting spring is in a stretched state, the lifting spring can drive the mounting plate and the electrical equipment to lift away from the bottom of the inner wall of the cabinet body.

[0013] According to the above technical solution, the extrusion plate is slidably installed inside the mounting plate. One side of the connecting spring is fixed inside the mounting plate, and the other side of the connecting spring is fixed to the outer wall of the extrusion plate. A moving seat is slidably installed on the side wall of the electrical equipment, and a mounting seat is fixed to the side wall of the electrical equipment. One side of the transmission spring is fixed to the top of the mounting seat, and the other side of the transmission spring is fixed inside the moving seat. The pressing rod is fixed to the outer wall of the moving seat, and the fixed rod is fixed to the side wall of the mounting seat. When the bent block moves outwards towards the outside of the cabinet, the bent block will no longer block the extrusion plate. And because the connecting spring is in a stretched state, the end of the extrusion block will squeeze the top inclined surface of the moving seat, causing the moving seat to move downwards, driving the pressing rod to tightly press the wire harness.

[0014] The present invention provides an automatic control cabinet for a generator set, having the following beneficial effects:

[0015] (1) By providing a shielding device in the present invention, when encountering heavy rain, the water inflow rate of the water inlet hole is larger than the water drainage rate of the drainage hole. Thus, when a large amount of rainwater accumulates in the water storage tank, the top plate becomes heavier and moves downwards. Through the cooperation of the hinge rod and the push block, two sets of protective plates can be pushed to unfold from the bottom of the top plate, expanding the protection on both sides of the cabinet body, preventing excessive rainwater from drifting onto the side wall of the cabinet body, and causing rainwater to flow along the outer wall of the cabinet body to the heat dissipation holes, resulting in damage to the internal electrical equipment. And when the protective plate flips and unfolds, the extrusion block is not under extrusion force. Through the cooperation of the push spring, the connecting block and the movable rod, the shielding plate can be squeezed to move to the door gap to shield and protect the door gap, preventing rainwater from entering the interior of the cabinet through the door gap.

[0016] (2) By providing a dredging device in the present invention, when the top plate moves downwards and the push block is squeezed by the hinge rod to move, the L-shaped connecting block can be driven to move. Through the cooperation of the rack and the gear, the rotating shaft can drive the scraper to rotate, so that the scraper can push away the impurities at the water inlet hole on the top of the top plate, preventing a large amount of impurities from adhering to the water inlet hole, which will affect the subsequent water inlet of the water inlet hole. And when the scraper rotates, the scraper can squeeze the inclined surface of the inclined block, causing the inclined block to move upwards. Through the cooperation of the connecting rod, the connecting seat and the fixed seat, the dredging plate can be moved upwards to eject the impurities stuck at the water inlet hole, preventing the impurities from getting stuck at the water inlet hole and further improving the cleaning operation of the water inlet hole.

[0017] (3) By providing an auxiliary device in the present invention, when the scraping plate rotates to the convex part at the top and contacts the bent stop block, the scraping plate will squeeze the bent stop block to move, causing the bent stop block to move away from the top of the mounting plate, thereby releasing the limit on the mounting plate. Since the lifting spring is in a stretched state, the lifting spring can drive the mounting plate and the electrical equipment to move upward, moving the electrical equipment away from the bottom of the cabinet, preventing a large amount of water accumulation on the ground caused by heavy rain from coming into contact with the electrical equipment and damaging the electrical equipment. And when the bent stop block moves, it does not block the pressing plate. Through the cooperation of the connecting spring, the moving seat, the transmission spring and the pressing rod, the pressing rod can tightly fix the cable plugged into the electrical equipment, preventing the water flow at the bottom of the cabinet from impacting the cabinet and causing the cabinet to shake, so that the cable becomes loose from the electrical equipment.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 10 , an embodiment of the present invention is: an automatic control cabinet for a generator set, including a cabinet body 1, heat dissipation holes 2 are opened on the side wall of the cabinet body 1, a sleeve 4 is fixed on the top of the cabinet body 1, a support column 5 is slidably installed on the inner wall of the sleeve 4, a support spring 6 is fixed at the bottom of the support column 5, the bottom of the support spring 6 is fixed on the inner wall of the sleeve 4, the top of the support column 5 is fixed with a top plate 7, a water storage tank 8 is opened inside the top plate 7, a water inlet hole is opened on the top of the top plate 7, and a drain hole is opened on the outer wall of the top plate 7. By setting the water inlet hole, when it rains, rainwater can enter the water storage tank 8 on the top plate 7 through the water inlet hole. An installation plate 9 is slidably installed on the inner wall of the cabinet body 1, an electrical equipment 3 is detachably installed at the bottom of the installation plate 9, the bottom of the electrical equipment 3 is attached to the bottom of the inner wall of the cabinet body 1, and a shielding device with good protection effect is arranged at the top of the electrical equipment 3;

[0031] Among them, the shielding device includes a push block 10, a hinge rod 11, a fixed block 12, a rotating rod 13, a protective plate 14, an extrusion block 15, a pushing spring 16, a movable rod 19, a connecting block 17 and a shielding plate 18; the push block 10 is slidably installed at the bottom of the top plate 7, the outer wall of the sleeve 4 is hinged with a hinge rod 11, and one end of the hinge rod 11 away from the sleeve 4 is hinged at the end of the push block 10, the fixed block 12 is fixed on the side wall of the top plate 7, the rotating rod 13 penetrates through the fixed block 12 and is rotatably connected at the penetration point, the protective plate 14 is fixed on the outer wall of the rotating rod 13, the extrusion block 15 is slidably installed on the top of the cabinet body 1, one side of the pushing spring 16 is fixed inside the top of the cabinet body 1, and the other side of the pushing spring 16 is fixed on the side wall of the extrusion block 15, the shielding plate 18 is slidably installed on the outer wall of the cabinet body 1, the connecting block 17 is fixed on the outer wall of the extrusion block 15, one end of the movable rod 19 is hinged on the outer wall of the shielding plate 18, and the other end of the movable rod 19 is hinged at the end of the connecting block 17.

[0032] There are two groups of protective plates 14, and the two groups of protective plates 14 are symmetrically arranged with the central line in the vertical direction of the cabinet body 1 as the axis of symmetry. By setting the protective plates 14, when it rains heavily, the water inflow volume of the water inlet holes on the top plate 7 will be greater than the drainage volume of the drainage holes, so that the gravity of the top plate 7 will become larger, causing the top plate 7 to move downward. Through the cooperation of the hinge rod 11 and the push block 10, the push block 10 can be pushed to expand the protective plate 14, and the protection range of the top plate 7 can be expanded, so that the protective plate 14 shields and protects both sides of the cabinet body 1, preventing excessive rainwater from making the rainwater drift onto the side walls of the cabinet body 1. When a large amount of rainwater flows down along the side walls of the cabinet body 1, it is easy to cause the rainwater to enter the cabinet body 1 from the heat dissipation holes 2, resulting in damage to the electrical equipment 3.

[0033] And when the protective plate 14 rotates and does not squeeze the extrusion block 15, through the cooperation of the connecting block 17 and the movable rod 19, the shielding plate 18 can be pushed to the door gap to shield and protect the door gap, preventing rainwater from entering the interior of the cabinet body 1 through the door gap.

[0034] A torsion spring is fixed at the protruding point of the end of the rotating rod 13, and the side wall of the torsion spring is fixed on the side wall of the protective plate 14. When the protective plate 14 is unfolded, the torsion spring will contract and deform, and the elastic coefficient of the torsion spring is five times that of the pushing spring 16. Therefore, when the torsion spring drives the protective plate 14 to reset, the protective plate 14 can be pushed to move the extrusion block 15, compressing the pushing spring 16.

[0035] During the operation of this embodiment: When using the control cabinet outdoors and encountering heavy rain, the water inflow through the water inlet holes at the top of the top plate 7 is greater than the drainage volume of the drainage holes, resulting in a large amount of rainwater entering the water storage tank 8 through the water inlet holes. When a large amount of rainwater accumulates in the water storage tank 8, the top plate 7 becomes heavier, squeezing the support column 5 to move into the sleeve 4 and compressing the support spring 6. When the top plate 7 moves downward, it can drive the push block 10 to move downward. Since the hinge rod 11 does not move downward, the hinge rod 11 can exert a squeezing force on the push block 10, causing the hinge rod 11 to rotate at the hinge, enabling the hinge rod 11 to push the push block 10 away from the support column 5. Thus, the push block 10 can squeeze the protective plate 14 to flip and unfold, causing the rotating rod 13 to rotate and driving the torsion spring to be compressed and deformed. When the two protective plates 14 are unfolded, the protection of both sides of the cabinet body 1 is improved. And when the protective plate 14 flips and unfolds, the protective plate 14 no longer squeezes the extrusion block 15. Since the push spring 16 is in a compressed state, the push spring 16 can drive the extrusion block 15 to move away from the support column 5, causing the extrusion block 15 to drive the connecting block 17 to move, and the connecting block 17 to squeeze the movable rod 19, causing the movable rod 19 to rotate at the hinge, enabling the movable rod 19 to squeeze the shielding plate 18 to move, and the shielding plate 18 to move to the door gap to block the door gap, preventing rainwater from entering the interior of the cabinet body 1 through the door gap.

[0036] When the rain stops, the drainage holes will drain the water accumulated in the water storage tank 8. Since the weight of the top plate 7 becomes lighter and the support spring 6 is in a compressed state, the support column 5 can drive the top plate 7 to reset. When the top plate 7 moves upward, it can drive the push block 10 to move upward, causing the hinge rod 11 to pull the push block 10 to reset, and the push block 10 no longer squeezes the protective plate 14. Since the torsion spring is in a compressed and deformed state, the torsion spring can drive the rotating rod 13 and the protective plate 14 to flip and reset, causing the protective plate 14 to squeeze the extrusion block 15, making the extrusion block 15 approach the support column 5, thereby driving the connecting block 17 to pull the movable rod 19, and the movable rod 19 to pull the shielding plate 18 to leave the door gap for reset, facilitating the opening of the cabinet door.

[0037] Please refer to Figures 1 - 10, on the basis of the above embodiments, in another embodiment of the present invention, a dredging device for preventing the blockage of the water inlet holes is provided on the top of the top plate 7, and an auxiliary device is provided on the bottom of the top plate 7. The dredging device includes an L-shaped connecting block 201, a rotating shaft 202, a gear 203, a rack 204, a scraper 205, an inclined block 206, a connecting rod 211, a return spring 207, a connecting seat 208, a fixing seat 209 and a dredging plate 210; the L-shaped connecting block 201 is fixed on the outer wall of the push block 10, the rack 204 is fixed on the side of the L-shaped connecting block 201 away from the push block 10, the rotating shaft 202 is rotatably installed on the top of the top plate 7, the scraper 205 is fixed on the outer wall of the rotating shaft 202, the gear 203 is fixed on the outer wall of the rotating shaft 202, the outside of the gear 203 meshes with the rack 204, the connecting rod 211 penetrates through the top of the top plate 7 and is slidably connected at the penetration point, the inclined block 206 is fixed on the top of the connecting rod 211, the connecting seat 208 is fixed on the bottom of the connecting rod 211, one side of the return spring 207 is fixed on the inner wall of the water storage tank 8, and the other side of the return spring 207 is fixed on the top of the connecting seat 208, the fixing seat 209 is fixed on the side wall of the connecting seat 208, and the dredging plate 210 is fixed on the top of the fixing seat 209.

[0038] There are two groups of scrapers 205, and the two groups of scrapers 205 are symmetrically arranged with the central line in the vertical direction of the cabinet body 1 as the axis of symmetry. When the top plate 7 moves downward and the push block 10 is pushed to move by the hinge rod 11, the L-shaped connecting block 201 can be driven to move. Through the cooperation of the rack 204 and the gear 203, the rotating shaft 202 can drive the scraper 205 to rotate, so that the scraper 205 can push away the impurities at the water inlet holes on the top of the top plate 7, preventing a large amount of impurities from adhering to the water inlet holes, which will affect the subsequent water inlet of the water inlet holes.

[0039] There are multiple groups of dredging plates 210, and they are arranged in a linear array on the top of the fixing seat 209. Through the cooperation of the connecting rod 211, the connecting seat 208 and the fixing seat 209, the dredging plate 210 can move upward, so that the dredging plate 210 can push out the impurities stuck at the water inlet holes, preventing the impurities from getting stuck at the water inlet holes and causing blockage.

[0040] The auxiliary device includes a bending stopper 221, a guide rod 222, a return spring 223, a pressing plate 224, a moving seat 226, a connecting spring 225, a transmission spring 228, a pressing rod 229, a fixing rod 230 and a mounting seat 227; the bending stopper 221 penetrates through the side wall of the cabinet body 1, and is slidably connected at the penetration point, the guide rod 222 is fixed inside the bending stopper 221, and the guide rod 222 penetrates through the back surface of the cabinet body 1, and is slidably connected at the penetration point, one side of the return spring 223 is fixed on the outer wall of the bending stopper 221, the other side of the return spring 223 is fixed on the outer wall of the cabinet body 1, the pressing plate 224 is slidably installed inside the mounting plate 9, one side of the connecting spring 225 is fixed inside the mounting plate 9, the other side of the connecting spring 225 is fixed on the outer wall of the pressing plate 224, the elastic coefficient of the return spring 223 is five times that of the connecting spring 225, the moving seat 226 is slidably installed on the side wall of the electrical equipment 3, the mounting seat 227 is fixed on the side wall of the electrical equipment 3, one side of the transmission spring 228 is fixed on the top of the mounting seat 227, the other side of the transmission spring 228 is fixed inside the moving seat 226, the elastic coefficient of the connecting spring 225 is five times that of the transmission spring 228, the pressing rod 229 is fixed on the outer wall of the moving seat 226, and the fixing rod 230 is fixed on the side wall of the mounting seat 227.

[0041] When the convex part at the top of the scraping plate 205 rotates to contact the bending stopper 221, the scraping plate 205 will squeeze the bending stopper 221 to move, so that the bending stopper 221 is removed from the top of the mounting plate 9, thereby releasing the limit on the mounting plate 9. Since the lifting spring 231 is in a stretched state, the lifting spring 231 can drive the mounting plate 9 and the electrical equipment 3 to move upward, so that the electrical equipment 3 is away from the bottom of the cabinet body 1, preventing a large amount of water from accumulating on the ground due to heavy rain, and the accumulated water contacts the electrical equipment 3, causing damage to the electrical equipment 3.

[0042] And when the bending stopper 221 moves, it does not block and squeeze the pressing plate 224. Through the cooperation of the connecting spring 225, the moving seat 226 and the pressing rod 229, the pressing rod 229 can tightly fix the cable inserted into the electrical equipment 3, preventing the water flow at the bottom of the cabinet body 1 from impacting the cabinet body 1, causing the cabinet body 1 to shake and the cable to become loose from the electrical equipment 3.

[0043] During the operation of this embodiment: when the push block 10 moves towards the side away from the support column 5, the push block 10 can drive the L-shaped connecting block 201 to move, so that the L-shaped connecting block 201 drives the rack 204 to move on the gear 203, driving the gear 203 to rotate, making the rotating shaft 202 drive the scraper 205 to rotate, and the scraper 205 rotates towards the water inlet hole, enabling the scraper 205 to push away the impurities at the water inlet hole, preventing blockage at the water inlet hole. And when the scraper 205 rotates towards the water inlet hole, the scraper 205 will contact the inclined surface of the inclined block 206, causing the inclined block 206 to move upward under force, so that the inclined block 206 can drive the connecting rod 211 to move upward, making the connecting seat 208 move upward, compressing the return spring 207. And when the connecting seat 208 moves upward, it drives the fixed seat 209 and the dredging plate 210 to move upward, making the dredging plate 210 extend into the water inlet hole to push out the impurities stuck in the water inlet hole. When the scraper 205 rotates to not contact the inclined block 206, due to the return spring 207 being in a compressed state, the return spring 207 can drive the connecting seat 208 to move downward, making the fixed seat 209 drive the dredging plate 210 to move downward for reset, and performing the next dredging operation. When the push block 10 resets upward, the push block 10 can move closer to the support column 5 for reset, making the L-shaped connecting block 201 drive the rack 204 to reset, so that the rack 204 drives the gear 203 to rotate, and the rotating shaft 202 drives the scraper 205 to rotate and reset.

[0044] When the convex part of the squeegee 205 rotates to contact the bent stopper 221, the convex part of the squeegee 205 will squeeze and move the bent stopper 221, causing the bent stopper 221 to move out from the back of the cabinet body 1. When the bent stopper 221 moves, it can drive the guide rod 222 to move out of the cabinet body 1, thereby stretching the return spring 223. And when the bent stopper 221 is removed from the top of the mounting plate 9, the limit on the mounting plate 9 can be released. Since the lifting spring 231 is in a stretched state, the lifting spring 231 can drive the mounting plate 9 to move upward, causing the mounting plate 9 to drive the height of the electrical equipment 3 to rise. And when the bent stopper 221 moves out of the cabinet body 1, the bent stopper 221 will not contact the pressing plate 224. And since the connecting spring 225 is in a stretched state, the connecting spring 225 can drive the pressing plate 224 to move inward of the mounting plate 9, so that the end of the pressing plate 224 presses the inclined surface of the moving seat 226, causing the moving seat 226 to move downward under the extrusion force, driving the transmission spring 228 to be compressed. And when the moving seat 226 moves downward, it can drive the pressing rod 229 to press the cable on the electrical equipment 3 against the fixed rod 230, preventing the water flow from impacting the cabinet body 1 and causing the cabinet body 1 to shake, so that the cable is loosened from the electrical equipment 3; When the squeegee 205 resets and does not contact the bent stopper 221, since the return spring 223 is in a stretched state, the bent stopper 221 is reset. When it is necessary to reset the electrical equipment 3, the bent stopper 221 can be first pushed to move out of the cabinet body 1, pushing the mounting plate 9 to move downward, stretching the lifting spring 231. When the mounting plate 9 moves to the bottom of the bent stopper 221, the bent stopper 221 is released. Through the cooperation of the return spring 223, the bent stopper 221 can move to the top of the mounting plate 9, thereby being able to limit the mounting plate 9 and the electrical equipment 3. When the bent stopper 221 resets, it can squeeze the pressing plate 224 to move, stretching the connecting spring 225, and the end of the pressing plate 224 does not press the inclined surface of the moving seat 226. And since the transmission spring 228 is in a compressed state, it can drive the moving seat 226 and the pressing rod 229 to move upward for resetting, releasing the pressing and fixing of the cable, preventing the cable from being pressed all the time, which is likely to cause cable damage.
