Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, in particular to a high-protection outdoor power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits.

[0003] In the Northeast region, it is relatively cold outdoors and often accompanied by heavy snow. Some outdoor distribution cabinets are under great pressure due to the snow on the top. It is easy for the top of the distribution cabinet to be over-pressured, resulting in damage to the distribution cabinet body. The heat dissipation ports of the distribution cabinet are all in an open state. The heat generated by the distribution cabinet when working is discharged through the heat dissipation ports. The snow at the heat dissipation port is easy to melt into water and then re-freeze in a low temperature environment, resulting in the heat dissipation port being blocked by possible snow and ice, affecting the normal ventilation and heat dissipation inside the distribution cabinet. For this reason, we propose a high-protection outdoor distribution cabinet. Summary of the invention

[0004] The purpose of the present invention is to provide a high-protection outdoor power distribution cabinet to solve the problems raised in the above background technology.

The rod rotates, and the rotating rod rotates clockwise at this time. The pawl on the surface of the rotating rod cannot be stuck on the ratchet on the surface of the active rod, and thus cannot drive the active rod to rotate. When the sleeve rod moves to the lowermost end, the connecting rod mechanism disengages from the rotating rod, and the rotating rod is no longer restricted. Under the action of the spiral spring, the rotating rod rotates counterclockwise. At this time, the pawl on the surface of the rotating rod is stuck on the ratchet on the surface of the active rod, driving the active rod to rotate counterclockwise. When the active rod drives the resistance protrusion to rotate, the resistance protrusion intermittently resists on the matching protrusion, and cooperates with the elastic effect of the rubber cloth to make the baffle plate swing back and forth at the position hinged with the frame, thereby shaking off the snow on the top of the baffle plate to avoid excessive snow accumulation, causing squeezing and excessive pressure on the whole, resulting in damage.

When the sleeve rod moves downward a certain distance with the cross bar and the sliding rod, the insertion rod can be inserted into the triangular groove at the bottom of the sliding rod. When the sliding rod continues to move downward When the cam is in the state of being moved upward, the stopper is pressed against the stopper and the stopper is pushed back to move the cam, so that the cam is pushed back to move the cam away from the rotation rod and the rotation rod is pushed back to move the cam.

[0014] Preferably, the de-icing assembly includes a slide plate, which is slidably mounted on the inner wall of the cabinet, an L-shaped rod is fixed to the top of the slide plate, the L-shaped rod passes through the cabinet, the L-shaped rod extends into the cavity, the top of the slide plate is penetrated by the telescopic rod and is rotatably connected to the telescopic rod, the telescopic rod passes through the cabinet and extends into the cavity, the telescopic rod is rotatably connected to the cabinet, the telescopic rod is transmission-connected to the active rod through a belt, a disc is fixed to the bottom of the telescopic rod, a push block is fixed to the bottom of the disc, a guide frame is slidably mounted on the inner wall of the slide plate, a connecting rod is fixed to the inner side of the guide frame, a fixing block is fixed to the side of the connecting rod away from the center of the cabinet, and the fixing block is away from the center of the cabinet One side of the connecting rod is penetrated by the shovel block and is slidably connected to the shovel block, a triangular block is fixed to the bottom of the shovel block, a spring 1 is fixed on the inner wall of the fixed block, and the end of the spring 1 away from the fixed block is fixed to the shovel block, a resistance plate is slidably installed on the inner wall of the cabinet, a pull rope is fixed on the top of the resistance plate, the pull rope penetrates the cabinet and extends into the cavity, the end of the pull rope away from the resistance plate is fixed to the pressure plate, and the pressure plate is slidably installed on the inner wall of the cavity, an extrusion block is fixed on the side of the sleeve rod, the bottom of the slide plate is penetrated by the extrusion roller and is slidably connected to the extrusion roller, when the sleeve rod moves downward, the sleeve rod moves with the extrusion block, the extrusion block no longer lifts the L-shaped rod, and the slide plate is lifted by its own weight. Under the action of force, the slide plate moves downward a certain distance, and as the sleeve rod continues to move downward with the extrusion block, the extrusion block abuts against the pressure plate, pushing the pressure plate downward together, and the pressure plate pulls the contact plate upward through the pull rope, and the contact plate abuts against the extrusion roller, pushing the extrusion roller to move upward in the slide plate, and the extrusion roller abuts against the triangular block at the bottom of the shovel block, pushing the shovel block to move to the side away from the fixed block, so that the shovel block extends into the heat dissipation port. When the active rod rotates, the active rod drives the telescopic rod to rotate through the belt, and the telescopic rod drives the disc and the push block to rotate, and the push block pushes the guide frame back and forth, so that the guide frame moves back and forth.

At the same time, when the sleeve rod moves downward, the slide plate can be controlled to move downward to block the heat dissipation vents to prevent the snow from entering the heat dissipation vents when the baffle plate shakes off the snow. When the sleeve rod moves upward, the extrusion block no longer presses the pressure plate. Under the action of the gravity of the resistance plate, the resistance plate moves downward and the resistance plate no longer presses the extrusion roller. Under the action of spring 1, the shovel block moves to the side close to the fixed block, so that the shovel block is no longer in the heat dissipation vent. After the sleeve rod is completely reset, the extrusion block fixed on the side of the sleeve rod contacts the L-shaped rod, pushing the L-shaped rod and the slide plate to move upward and reset.

[0015] Preferably, the slide plate is provided with inclined vents. When the slide plate is in a reset state, the vents on the slide plate overlap with the heat dissipation ports, so that the cabinet can be normally ventilated and heat dissipated. Moreover, by setting the inclined vents, it is possible to effectively prevent ice and snow that may exist on the inside of the heat dissipation ports from melting, causing water to flow into the cabinet through the heat dissipation ports.

The moving rod pushes the push rod to move to the side close to the sleeve rod through the support rod, and the push rod contacts the contact rubber plate, pushing the contact rubber plate to contact the fixed rod, and cooperating with the card teeth on the surface of the fixed rod to limit the sleeve rod, ensuring that the baffle and the frame will not reset upward during the process of the active rod rotating to control the baffle to shake off the snow on the top.

[0017] Compared with the prior art, the present invention provides a high-protection outdoor power distribution cabinet, which has the following beneficial effects:

[0018] 1. The high-protection outdoor distribution cabinet, through the shielding components and driven parts, when there is too much snow on the top of the baffle, the baffle, frame and sleeve rod move downward under the pressure of the snow. After they fall completely, the active rod can be controlled to rotate by the rotating rod, so that the active rod drives the resisting protrusion to squeeze the matching protrusion, and the baffle is controlled to swing back and forth at the position where it is hinged with the frame, so as to shake off the snow on the top of the baffle, avoid excessive snow accumulation, which will cause the whole to be squeezed and subjected to excessive pressure, resulting in damage.

[0019] 2. The high-protection outdoor distribution cabinet is provided with a shielding component, a driven part and a de-icing component. When the sleeve rod moves downward a certain distance, as the sleeve rod continues to move downward with the extrusion block, the extrusion block abuts on the pressure plate, pushing the pressure plate to move downward together, and the pressure plate pulls the contact plate upward through the pull rope, and the contact plate abuts on the extrusion roller, pushing the extrusion roller to move upward in the slide plate, and the extrusion roller abuts on the triangular block located at the bottom of the shovel block, pushing the shovel block to move to the side away from the fixed block, so that the shovel block extends into the heat dissipation port. When the active rod rotates, the active rod drives the telescopic rod to rotate through the belt, and the telescopic rod drives the disc and the push block to rotate, and the push block pushes the guide frame back and forth, so that the guide frame moves back and forth. At this time, the guide frame drives the connecting rod, the fixed block and the shovel block to move back and forth, so as to control the shovel block to shovel away the ice and snow that may exist in the heat dissipation port, so as to avoid the ice and snow blocking the heat dissipation port and affecting the normal ventilation and heat dissipation inside the cabinet.

[0020] 3. The high-protection outdoor distribution cabinet has inclined vents on the slide plate. The vents can overlap with the heat dissipation ports, which can provide normal ventilation and heat dissipation for the cabinet. At the same time, it can prevent ice and snow on the inside of the heat dissipation ports from melting and water from flowing into the cabinet through the heat dissipation ports.

[0021] 4. The high-protection outdoor distribution cabinet, through the set shielding component, driven part and locking component, can control the resistance rubber plate to resist the surface of the fixed rod when the active rod rotates, limit the sleeve rod, and ensure that in the process of controlling the baffle to shake off the snow on the top, the baffle and the frame cannot be reset upward, thereby effectively clearing the snow.

[0038] The shielding assembly 2 includes a fixing rod 21, the bottom of which is fixed on the inner wall of the cavity 6, the fixing rod 21 passes through the sleeve rod 22 and is slidably connected with the sleeve rod 22, the sleeve rod 22 passes through the top of the cabinet 1, a return spring 23 is fixed to the bottom of the sleeve rod 22, one end of the return spring 23 away from the sleeve rod 22 is fixed to the surface of the fixing rod 21, a frame 24 is fixed to the top of the sleeve rod 22, a baffle 25 is hinged on the inner side of the frame 24, a rubber cloth 26 is fixed on the inner side of the frame 24, and one end of the rubber cloth 26 away from the frame 24 is fixed to the baffle 25, the top of the cabinet 1 is shielded by the frame 24, the baffle 25 and the rubber cloth 26, which effectively shields the cabinet 1 from rain and snow, prevents the cabinet 1 from being directly eroded by rain and snow, and at the same time prevents the accumulated snow from squeezing the top of the cabinet 1.

[0039] The driven part 3 includes a rotating rod 31, which is rotatably mounted on the inner wall of the cavity 6. A spiral spring 32 is fixed to the surface of the rotating rod 31, and one end of the spiral spring 32 away from the rotating rod 31 is fixed to the inner wall of the cavity 6. A spiral groove 33 is opened on the surface of the rotating rod 31, a connecting rod mechanism 34 is arranged between the sleeve rod 22 and the rotating rod 31, and a pawl 35 is arranged on the surface of the rotating rod 31. An active rod 36 is rotatably mounted on the inner wall of the cavity 6, and a ratchet 37 is arranged on the surface of the active rod 36. A resisting protrusion 38 is fixed to the top of the active rod 36, and a matching protrusion 39 is fixed to the bottom of the baffle 25. When too much snow accumulates on the top of the frame 24 and the baffle 25, under the action of the gravity pressure of the snow, the frame 24 and the baffle 25 move downward with the sleeve rod 22, and the sleeve rod 22 can control the rotation of the rotating rod 31 through the connecting rod mechanism 34. The pawl 35 on the surface of the rotating rod 31 cannot be stuck on the ratchet 37 on the surface of the active rod 36, and thus cannot drive the active rod 36 to rotate. When the sleeve rod 22 moves to the lowermost end, the connecting rod mechanism 34 disengages from the rotating rod 31, and the rotating rod 31 is no longer restricted. Under the action of the spiral spring 32, the rotating rod 31 rotates counterclockwise. At this time, the pawl 35 on the surface of the rotating rod 31 is stuck on the ratchet 37 on the surface of the active rod 36, driving the active rod 36 to rotate counterclockwise. When the active rod 36 drives the resistance protrusion 38 to rotate, the resistance protrusion 38 intermittently resists on the matching protrusion 39, and cooperates with the elastic effect of the rubber cloth 26 to make the baffle 25 swing back and forth at the position hinged with the frame 24, thereby shaking off the snow on the top of the baffle 25 to avoid excessive snow accumulation, causing squeezing and excessive pressure on the whole, resulting in damage.

[0040] The connecting rod mechanism 34 includes a cross bar 341, one end of which is fixed to the side of the sleeve rod 22, and the other end of the cross bar 341 passes through the sliding rod 342 and is slidably connected to the sliding rod 342. One end of the sliding rod 342 is inserted into the spiral sliding groove 33, and the other end of the sliding rod 342 is fixed with a connecting spring 343, and the end of the connecting spring 343 away from the sliding rod 342 is fixed to the surface of the cross bar 341. When the sliding rod 342 is inserted into the spiral sliding groove 33, the sleeve rod 22 drives the sliding rod 342 to move downward through the cross bar 341, and the sliding rod 342 can abut against the spiral sliding groove 33, so that the rotating rod 31 rotates clockwise.

A tension spring 58 is fixed to the left side of the push rod 57. The end of the tension spring 58 away from the push rod 57 is fixed to the inner wall of the cavity 6. When the sleeve rod 22 moves downward with the cross bar 341 and the slide bar 342 for a certain distance, the insertion rod 52 can be inserted into the triangular groove 51 at the bottom of the slide bar 342. When the slide bar 342 continues to move downward, the insertion rod 52 is pushed so that the insertion rod 52 is aligned with the cavity 6. The hinged position swings toward the side away from the rotating rod 31, thereby pushing the sliding rod 342 to move toward the side away from the rotating rod 31, so that the sliding rod 342 withdraws from the spiral sliding groove 33 on the surface of the rotating rod 31. When the round hole 54 at the top of the sliding rod 342 moves to the position of the blocking block 55, under the action of the resistance spring 56, the blocking block 55 is inserted into the round hole 54 to limit the sliding rod 342. When the sleeve rod 22 brings the cross bar 341 and the sliding rod 342 back to the original position, the resistance rod 57 can be inserted into the round hole 54, and the resistance rod 57 can be inserted into the round hole 54. 7 abuts against the positioning block 55, pushing the positioning block 55 so that the positioning block 55 withdraws from the circular hole 54, thereby releasing the limit on the slide bar 342.

A triangular block 410 is fixed to the bottom of the shovel block 49. A spring 411 is fixed to the inner wall of the fixed block 48. The end of the spring 411 away from the fixed block 48 is fixed to the shovel block 49. A contact plate 412 is slidably installed on the inner wall of the cabinet 1. A pull rope 413 is fixed to the top of the contact plate 412. The pull rope 413 penetrates the cabinet 1 and extends into the cavity 6. The end of the pull rope 413 away from the contact plate 412 is fixed to a pressure plate 414. The pressure plate 414 is slidably installed on the inner wall of the cavity 6. An extrusion block 415 is fixed to the side of the sleeve rod 22. The bottom of the slide plate 41 is penetrated by the extrusion roller 416 and is slidably connected to the extrusion roller 416. When the sleeve rod 22 moves downward, the sleeve rod 22 carries the extrusion block 415 moves together, the squeezing block 415 no longer lifts the L-shaped rod 42, and under the action of the slide plate 41's own gravity, the slide plate 41 moves downward a certain distance, as the sleeve rod 22 continues to move downward with the squeezing block 415, the squeezing block 415 abuts on the pressure plate 414, pushing the pressure plate 414 to move downward together, the pressure plate 414 pulls the contact plate 412 upward through the pull rope 413, the contact plate 412 abuts on the squeezing roller 416, pushing the squeezing roller 416 to move upward in the slide plate 41, the squeezing roller 416 abuts on the triangular block 410 located at the bottom of the shovel block 49, pushing the shovel block 49 to move to the side away from the fixed block 48, so that the shovel block 49 extends into the heat dissipation port 7, and when the active rod 36 rotates, the active rod 36 drives the telescopic rod 4 through the belt 3 rotates, the telescopic rod 43 drives the disc 44 and the push block 45 to rotate, and the push block 45 pushes the guide frame 46 back and forth, so that the guide frame 46 moves back and forth. At this time, the guide frame 46 drives the connecting rod 47, the fixing block 48 and the shovel block 49 to move back and forth, so as to control the shovel block 49 to shovel away the ice and snow that may exist in the heat dissipation port 7, so as to prevent the ice and snow from blocking the heat dissipation port 7 and affecting the normal ventilation inside the cabinet 1. At the same time, when the sleeve rod 22 moves downward, the slide plate 41 can be controlled to move downward to block the heat dissipation port 7, so as to prevent the snow from entering the heat dissipation port 7 when the baffle plate 25 is shaking off the snow.

After the sleeve rod 22 is completely reset, the squeezing block 415 fixed on the side of the sleeve rod 22 abuts against the L-shaped rod 42, pushing the L-shaped rod 42 and the slide plate 41 to move upward and reset.

[0043] An inclined vent 9 is provided on the slide plate 41. When the slide plate 41 is in the reset state, the vent 9 on the slide plate 41 overlaps with the heat dissipation port 7, so that the cabinet 1 can be normally ventilated and heat dissipated. In addition, the inclined vent 9 can effectively prevent ice and snow that may exist on the inner side of the heat dissipation port 7 from melting, and water from flowing into the interior of the cabinet 1 through the heat dissipation port 7.

[0044] A locking assembly 8 is provided in the cavity 6, and the locking assembly 8 includes a fixed plate 81, the fixed plate 81 is penetrated by the active rod 36 and fixedly connected to the active rod 36, a cam 82 is fixed on the surface of the fixed plate 81, a moving rod 83 is slidably mounted on the inner wall of the cavity 6, and the end of the moving rod 83 away from the fixed plate 81 is hinged with a support rod 84, and the end of the support rod 84 away from the moving rod 83 is hinged with a push rod 85, and the push rod 85 is slidably mounted on the inner wall of the cavity 6, the side of the sleeve rod 22 is penetrated by the resisting rubber plate 86 and slidably connected to the resisting rubber plate 86, the surface of the fixed rod 21 is provided with a latch, and a spring piece 87 is fixed on the inner wall of the sleeve rod 22, and the spring piece 87 is away from the sleeve rod One end of 22 is fixed to the abutment rubber plate 86. When the active rod 36 rotates, the active rod 36 drives the fixed plate 81 and the cam 82 to rotate together. The cam 82 can abut on the moving rod 83, pushing the moving rod 83 to move to the side away from the fixed plate 81. The moving rod 83 pushes the push rod 85 to move to the side close to the sleeve rod 22 through the support rod 84. The push rod 85 abuts on the abutment rubber plate 86, pushing the abutment rubber plate 86 to abut against the fixed rod 21, and cooperates with the latching teeth on the surface of the fixed rod 21 to limit the sleeve rod 22, ensuring that when the active rod 36 rotates to control the baffle plate 25 to shake off the snow on the top, the baffle plate 25 and the frame 24 will not reset upward.

[0045] Based on the above embodiment, when there is too much snow on the top of the baffle plate 25, under the action of the gravity of the snow, the frame 24, the baffle plate 25 and the sleeve rod 22 move downward. In the process of the sleeve rod 22 moving downward, the sleeve rod 22 moves downward with the cross bar 341 and the slide bar 342, and the slide bar 342 slides downward in the spiral slide groove 33 on the surface of the rotating rod 31, so that the rotating rod 31 rotates. At this time, the rotating rod 31 rotates clockwise, and the rotating rod 31 winds up and accumulates force on the spiral spring 32. When the sleeve rod 22 moves downward with the cross bar 341 and the slide bar 342 for a certain distance, the insertion rod 52 can be inserted into the triangular groove 51 at the bottom of the slide bar 342. When the slide bar 342 continues to move downward, it pushes the insertion rod 52, so that the insertion rod 52 moves away from the rotating rod 31 at the position hinged with the cavity 6. The cam 35 is engaged with the ratchet wheel 37 on the surface of the active rod 36, driving the active rod 36 to rotate counterclockwise. When the active rod 36 drives the abutment protrusion 38 to rotate, the abutment protrusion 38 intermittently abuts against the matching protrusion 39, and cooperates with the elastic effect of the rubber cloth 26 to make the baffle 25 swing back and forth at the position hinged with the frame 24, thereby shaking off the snow on the top of the baffle 25, avoiding excessive snow accumulation, causing squeezing and causing the overall pressure to be too large, resulting in damage.

[0046] When the active rod 36 rotates, the active rod 36 drives the fixed plate 81 and the cam 82 to rotate together. The cam 82 can abut against the moving rod 83, pushing the moving rod 83 to move to the side away from the fixed plate 81. The moving rod 83 pushes the push rod 85 to move to the side close to the sleeve rod 22 through the support rod 84. The push rod 85 abuts against the contact rubber plate 86, pushing the contact rubber plate 86 to contact the fixed rod 21, and cooperates with the locking teeth on the surface of the fixed rod 21 to limit the sleeve rod 22, ensuring that when the active rod 36 rotates and controls the baffle plate 25 to shake off the snow on the top, the baffle plate 25 and the frame 24 will not reset upward.

[0047] When the sleeve rod 22 moves downward, the sleeve rod 22 moves with the squeezing block 415, and the squeezing block 415 no longer lifts the L-shaped rod 42. Under the action of the slide plate 41's own gravity, the slide plate 41 moves downward a certain distance. As the sleeve rod 22 continues to move downward with the squeezing block 415, the squeezing block 415 abuts against the pressure plate 414, pushing the pressure plate 414 to move downward together. The pressure plate 414 pulls the contact plate 412 upward through the pull rope 413, and the contact plate 412 abuts against the squeezing roller 416, pushing the squeezing roller 416 to move upward in the slide plate 41. The squeezing roller 416 abuts against the triangular block 410 located at the bottom of the shovel block 49, pushing the shovel block 49 to move to the side away from the fixed block 48, so that the shovel The block 49 extends into the heat dissipation port 7. When the active rod 36 rotates, the active rod 36 drives the telescopic rod 43 to rotate through the belt, and the telescopic rod 43 drives the disc 44 and the push block 45 to rotate. The push block 45 pushes the guide frame 46 back and forth, so that the guide frame 46 moves back and forth. At this time, the guide frame 46 drives the connecting rod 47, the fixed block 48 and the shovel block 49 to move back and forth, so as to control the shovel block 49 to shovel away the ice and snow that may exist in the heat dissipation port 7, so as to prevent the ice and snow from blocking the heat dissipation port 7 and affecting the normal ventilation inside the cabinet 1. At the same time, when the sleeve rod 22 moves downward, the slide plate 41 can be controlled to move downward to block the heat dissipation port 7, so as to prevent the snow from entering the heat dissipation port 7 when the baffle 25 shakes off the snow.

[0048] After the active rod 36 stops rotating, since the spiral spring 32 drives the rotating rod 31 to rotate counterclockwise, the rotating rod 31 will return to its initial state, and the active rod 36 will also maintain its initial state, so that the cam 82 on the surface of the fixed plate 81 no longer resists the moving rod 83. Under the action of the spring 87, the resisting rubber plate 86 pushes the push rod 85 to reset, thereby releasing the limit on the sleeve rod 22. Under the action of the reset spring 23, the sleeve rod 22 resets upward with the frame 24 and the baffle 25.

[0049] When the sleeve rod 22 is reset upward with the cross bar 341 and the slide bar 342, the push rod 57 can be inserted into the circular hole 54, and the push rod 57 abuts against the blocking block 55, pushing the blocking block 55 so that the blocking block 55 withdraws from the circular hole 54, thereby releasing the limit on the slide bar 342. At this time, under the action of the connecting spring 343, the slide bar 342 moves to the side close to the rotating rod 31 and resets, and the slide bar 342 is reinserted into the spiral groove 33. At this time, the push rod 57 is pulled by the slide bar 342 to move together. When the slide bar 342 moves downward a certain distance, the push rod 57 withdraws from the circular hole 54, and under the action of the tension spring 58, the push rod 57 is reset.

[0050] When the sleeve rod 22 moves upward, the extrusion block 415 no longer squeezes the pressure plate 414. Under the action of the gravity of the contact plate 412, the contact plate 412 moves downward, and the contact plate 412 no longer squeezes the extrusion roller 416. Under the action of the spring 1 411, the shovel block 49 moves to the side close to the fixed block 48, so that the shovel block 49 is no longer in the heat dissipation port 7. After the sleeve rod 22 is completely reset, the extrusion block 415 fixed on the side of the sleeve rod 22 contacts the L-shaped rod 42, pushing the L-shaped rod 42 and the slide plate 41 to move upward and reset. The vent 9 on the slide plate 41 coincides with the heat dissipation port 7, so that the cabinet 1 can be ventilated and dissipated normally. In addition, by setting the inclined vent 9, it can be effectively avoided that when the ice and snow on the inner side of the heat dissipation port 7 melt, water flows into the cabinet 1 through the heat dissipation port 7.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
