[0016] The beneficial effects of the present invention are as follows: 1. The power distribution cabinet for smart grids described in the present invention utilizes a centralized discharge foreign matter removal mechanism to remove impurities from the outer shell surface of the power distribution cabinet body, thereby avoiding the situation where impurities adhere to the filter surface, affecting the heat dissipation effect, and impurities corrode the metal shell of the power distribution cabinet body, thereby affecting the service life of the power distribution cabinet body. In addition, the removed impurities will be concentrated in the same place and discharged to the surrounding drainage system, thereby avoiding the situation where the removed impurities remain around the power distribution cabinet body and are easily attached to the surface of the power distribution cabinet body again due to the action of wind.

[0017] 2. In the distribution cabinet for smart grid described in the present invention, when the pressure sensor is squeezed by the pressure block, a pressure value will be detected. The pressure value can be used to determine whether there are impurities staying in the conveying plate or the gathering plate. If the impurities stay, scraper one and scraper two will move horizontally and cooperate with each other to push the impurities to the drain pipe, so that the impurities are discharged smoothly with the water flow, thereby avoiding the situation where the impurities contaminated on the outer shell of the distribution cabinet body are heavy and cannot be washed away by the water flow when falling into the conveying plate or the gathering plate, causing the impurities to accumulate in the groove and block the drainage channel composed of the conveying plate and the gathering plate, thereby affecting the subsequent discharge of impurities, and the impurities are also easily attached to the surface of the distribution cabinet body again. In addition, scraper one and scraper two will only work when the pressure value detected by the pressure sensor continues to remain unchanged. If the pressure value detected by the pressure sensor is always normal, scraper one and scraper two will not work, and the impurities can be washed away by water flow alone, which saves more electricity resources.

[0018] 3. The power distribution cabinet for smart grid described in the present invention, when the scraper moves to the drain pipe, if the pressure sensor value still does not decrease, it means that impurities are stuck in the drain pipe mouth, then the slide moves to make the collecting plate away from the surface of the distribution cabinet body, and then the collecting plate flips over to pour out the impurities in the collecting plate, thereby avoiding the situation where the impurities are pushed to the drain pipe and cannot be discharged with the water flow because they are stuck in the drain pipe mouth, which still affects the subsequent impurity discharge. If the impurities can be discharged smoothly after being pushed by the scraper, the electric push rod and the motor 2 do not work, which also saves electricity resources. Moreover, when the collecting plate pours out the impurities, the impurities are in a gathered state and away from the distribution cabinet body, which is beneficial to reduce the probability of impurities being attached to the distribution cabinet body again due to wind force.

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please refer to Figures 1-10 The present invention provides a technical solution: a power distribution cabinet for a smart grid, comprising a power distribution cabinet body 1, wherein filters 4 are provided at heat dissipation openings on both sides of the power distribution cabinet body 1, and a centralized discharge foreign matter removal mechanism is also provided on the power distribution cabinet body 1; The centralized discharge type foreign matter removal mechanism includes a slide bar 18 fixedly connected to both ends of the rear side of the distribution cabinet body 1, the slide bar 18 is slidably connected to the lifting plate 20, and both sides of one end of the lifting plate 20 are slidably connected to the sliding column 26, the upper end of the sliding column 26 is fixedly connected to the conveying plate 8, and both sides of the bottom of the conveying plate 8 are slidably connected to the slide plate 9, and one end of the slide plate 9 is rotatably provided with a gathering plate 6, and one end of the gathering plate 6 is connected to the drain pipe 5, and the drain pipe 5 is a hose. A plurality of scraper pads 25 are fixedly connected to the conveying plate 8, and a scraper pad 2 31 is fixedly connected to one side of the gathering plate 6. The edges of the scraper pad 1 25 and the scraper pad 2 31 are in contact with the surface of the distribution cabinet body 1, and the upper end face of the distribution cabinet body 1 is fixedly connected to the water tank 2, and one side of the water tank 2 is connected to the water outlet pipe 3.

[0024] In this embodiment, Figure 7 and Figure 8 As shown, one side of the lifting plate 20 is threadedly connected to a threaded rod three 17, both ends of the threaded rod three 17 are rotatably set on the distribution cabinet body 1, and one side of the upper end of the distribution cabinet body 1 is fixedly connected to a motor four 16, and the output end of the motor four 16 is fixedly connected to one end of the threaded rod three 17.

[0025] Specifically, in some cases, the existing smart grid distribution cabinet is installed outdoors to meet different usage requirements. When the distribution cabinet is outdoors, its shell is easily contaminated with impurities, and a filter 4 is provided at the heat dissipation port of the distribution cabinet. The filter 4 can prevent dust and other impurities from entering the distribution cabinet. When impurities adhere to the surface of the filter 4, the heat dissipation effect is affected. In addition, the impurities may corrode the metal shell of the distribution cabinet, thereby affecting the service life of the distribution cabinet. Therefore, in order to solve the above problems, when this embodiment is in use, the distribution cabinet body 1 is installed at a designated location outdoors, and the lower end of the drain pipe 5 is connected to the surrounding drainage system, a certain amount of water is added to the water tank, and rainwater during rain will also enter the water tank 2 to be collected. At regular intervals, the motor four 16 drives the threaded rod three 17 to rotate, so that the lifting plate 20 rises. When the lifting plate 20 rises, the conveying plate 8 and the gathering plate 6 will also rise. Since the scraper pad 1 25 and the scraper pad 2 31 are in contact with the surface of the distribution cabinet body 1, impurities contaminated on the outer shell of the distribution cabinet body 1 can be scraped off, and the impurities fall into the grooves of the conveying plate 8 and the gathering plate 6. When the conveying plate 8 rises to the upper edge of the distribution cabinet body 1, all impurities on the surface of the distribution cabinet body 1 are scraped off, and at this time the end of the outlet pipe 3 is aligned with the groove of the conveying plate 8, and the valve on the outlet pipe 3 is opened. The water in the water tank 2 flows into the groove of the conveying plate 8. Since the bottom of the groove of the conveying plate 8 is an inclined surface, the water flow can flow along the groove of the conveying plate 8 to the gathering plate 6. At the same time, after the water flow is in the gathering plate 6, it will flow to the drain pipe 5 due to the inclination of the bottom of the gathering plate 6. The impurities in the grooves of the conveying plate 8 and the gathering plate 6 will be discharged from the drain pipe 5 to the drainage system along with the water flow, which can realize the removal of impurities on the outer shell of the distribution cabinet body 1, avoiding the situation that impurities adhere to the surface of the filter 4, affecting the heat dissipation effect, and impurities corrode the metal shell of the distribution cabinet body 1, affecting the service life of the distribution cabinet body 1, and the removed impurities will be concentrated in the same place and discharged to the drainage system, avoiding the situation that the removed impurities are still in the periphery of the distribution cabinet body 1 and the impurities are easily attached to the surface of the distribution cabinet body 1 again due to the action of wind.

[0026] In this embodiment, Figures 1-8 As shown, an electric push rod 10 is fixedly connected to one side of the lower end surface of the conveying plate 8, the piston end of the electric push rod 10 is fixedly connected to one end of the slide 9, and one end of the slide 9 is fixedly connected to a motor 2 13, and the output end of the motor 2 13 is fixedly connected to one end of the gathering plate 6.

[0027] A pressure block 28 is provided on one side of the lower end surface of the conveying plate 8 , and a pressure sensor 27 is fixedly connected to one side of the upper end surface of the lifting plate 20 , and the pressure block 28 is in contact with the pressure sensor 27 .

[0028] One side of the gathering plate 6 and the conveying plate 8 is slidably connected to a slider 15, one side of the upper end of the slider 15 is slidably connected to two slide rods 22, and the lower end of the slide rod 22 is fixedly connected to a scraper 1 23.

[0029] One end of the slide rod 22 is provided with a spring 24, one end of the spring 24 is fixedly connected to the slider 15, and the other end is fixedly connected to one end of the slide rod 22. Both ends of one side of the gathering plate 6 and the conveying plate 8 are rotatably provided with a threaded rod 7, and the threaded rod 7 is threadedly connected to one end of the slider 15.

[0030] One side of the gathering plate 6 and the conveying plate 8 is fixedly connected to a motor three 14, and the output end of the motor three 14 is fixedly connected to one end of the threaded rod one 7.

[0031] Both sides of the conveying plate 8 are slidably connected with sliders 2 19, both sides of the sliders 2 19 are slidably connected with slide rods 30, the lower end of the slide rods 30 is fixedly connected with scraper 29, and the bottom of the scraper 29 fits with the bottom of the groove of the conveying plate 8.

[0032] One end of the slider 2 19 is threadedly connected to the threaded rod 2 11 , and both ends of the threaded rod 2 11 are rotatably set on the conveying plate 8 . Both sides of the conveying plate 8 are fixedly connected to the motor 12 , and the output end of the motor 12 is fixedly connected to one end of the threaded rod 2 11 .

[0033] One end of the slide bar 3 30 is sleeved with a spring 1 21 , one end of the spring 1 21 is fixedly connected to the slider 2 19 , and the other end is fixedly connected to one end of the slide bar 30 .

[0034] Specifically, in the above embodiment, although the impurities in the conveying plate 8 and the collecting plate 6 can be discharged to the drainage system by water flow, in some cases, the weight of the impurities on the outer shell of the distribution cabinet body 1 may be relatively large. When they fall onto the conveying plate 8 or the collecting plate 6, they may not be washed away by the water flow, resulting in the accumulation of impurities in the groove. In the long run, this may easily lead to the blockage of the drainage channel formed by the conveying plate 8 and the collecting plate 6, affecting the subsequent discharge of impurities, and the impurities are also likely to adhere to the surface of the distribution cabinet body 1 again; Therefore, in order to solve the above problems, when the present embodiment is in use, the pressure sensor 27 is squeezed by the pressure block 28 and the pressure value is detected. When impurities fall into the conveying plate 8 and the gathering plate 6, the pressure value will increase, and when the water flow washes away the impurities, the pressure value will change from large to small and finally be at a fixed value. If the pressure value does not decrease after increasing, it means that impurities remain in the conveying plate 8 or the gathering plate 6, then the motor three 14 and the motor one 12 are started, and under the action of the motor three 14 driving the threaded rod one 7 to rotate and the motor one 12 driving the threaded rod two 11 to rotate, the scraper one 23 and the scraper two 29 are moved laterally, and the scraper one 23 located in the groove of the conveying plate 8 moves laterally first, pushing the impurities to the grooves on both sides of the conveying plate 8, and then the scraper two 29 pushes the impurities to the gathering plate 6, the scraper 1 23 at the last gathering plate 6 moves horizontally to push the impurities to the drain pipe 5, so that the impurities are discharged smoothly with the water flow, thereby avoiding the situation where the impurities contaminated on the outer shell of the distribution cabinet body 1 are heavy and cannot be washed away by the water flow when falling onto the conveying plate 8 or the gathering plate 6, causing the impurities to accumulate in the groove and block the drainage channel composed of the conveying plate 8 and the gathering plate 6, thereby affecting the subsequent discharge of impurities, and the impurities are also likely to adhere to the surface of the distribution cabinet body 1 again. In addition, the scraper 1 23 and the scraper 2 29 only work when the pressure value detected by the pressure sensor 27 continues to remain unchanged. If the pressure value detected by the pressure sensor 27 is always normal, the scraper 1 23 and the scraper 2 29 do not work, and the impurities can be washed away by the water flow alone, which saves more power resources. Moreover, although the impurities can be pushed by scraper 1 23 and scraper 2 29 to promote the discharge of impurities, some impurities may be large in volume. When the impurities are pushed to the drain pipe 5, they may be stuck at the pipe mouth of the drain pipe 5 and cannot be discharged with the water flow, which still affects the subsequent discharge of impurities. Therefore, in order to avoid this situation, when scraper 1 23 moves to the drain pipe 5, if the value of pressure sensor 27 still does not decrease, it means that the impurities are stuck at the pipe mouth of the drain pipe 5, then the electric push rod 10 drives the slide plate 9 to move, so that the gathering plate 6 is away from the surface of the distribution cabinet body 1, and then the motor 2 13 drives the gathering plate 6 to flip The impurities in the collecting plate 6 are poured out, thereby preventing the impurities from being pushed to the drain pipe 5 and being stuck at the mouth of the drain pipe 5 and unable to be discharged with the water flow, which still affects the subsequent discharge of impurities. The electric push rod 10 and the motor 2 13 are also started after the scraper 1 23 works. If the impurities can be discharged smoothly after being pushed by the scraper 1 23, the electric push rod 10 and the motor 2 13 do not work, which also saves electricity resources. In addition, when the collecting plate 6 pours out the impurities, the impurities are in a gathered state and away from the distribution cabinet body 1, which is beneficial to reduce the probability of impurities being attached to the distribution cabinet body 1 again with wind force.

[0035] Working principle: The distribution cabinet body 1 is installed at a designated location outdoors, and the lower end of the drain pipe 5 is connected to the surrounding drainage system. A certain amount of water is added to the water tank, and rainwater will also enter the water tank 2 to be collected. At regular intervals, the motor 4 16 drives the threaded rod 3 17 to rotate, so that the lifting plate 20 rises. When the lifting plate 20 rises, the conveying plate 8 and the gathering plate 6 will also rise. Since the scraper pad 1 25 and the scraper pad 2 31 are in contact with the surface of the distribution cabinet body 1, impurities contaminated on the outer shell of the distribution cabinet body 1 can be scraped off, and the impurities fall into the grooves of the conveying plate 8 and the gathering plate 6. When the conveying plate 8 rises to the upper edge of the distribution cabinet body 1, all impurities on the surface of the distribution cabinet body 1 are scraped off, and at this time the end of the outlet pipe 3 is aligned with the groove of the conveying plate 8, the valve on the outlet pipe 3 is opened, and the water in the water tank 2 flows into the water tank 2. In the groove of the conveying plate 8, since the bottom of the groove of the conveying plate 8 is an inclined surface, the water flow can flow along the groove of the conveying plate 8 to the gathering plate 6. At the same time, after the water flow is in the gathering plate 6, it will flow to the drain pipe 5 due to the inclination of the bottom of the gathering plate 6. Then, the impurities in the grooves of the conveying plate 8 and the gathering plate 6 will be discharged from the drain pipe 5 to the drainage system along with the water flow, which can achieve the removal of impurities on the outer shell of the distribution cabinet body 1, avoiding the situation that impurities adhere to the surface of the filter 4 and affect the heat dissipation effect, and impurities corrode the metal shell of the distribution cabinet body 1 and affect the service life of the distribution cabinet body 1. In addition, the removed impurities will be concentrated in the same place and discharged to the drainage system, avoiding the situation that the removed impurities are still in the periphery of the distribution cabinet body 1 and the impurities are easily attached to the surface of the distribution cabinet body 1 again due to the action of wind.When the pressure sensor 27 is squeezed by the pressure block 28, the pressure value will be detected. When impurities fall into the conveying plate 8 and the gathering plate 6, the pressure value will increase, and when the water flow washes away the impurities, the pressure value will change from large to small and finally to a fixed value. If the pressure value does not decrease after increasing, it means that impurities are staying in the conveying plate 8 or the gathering plate 6, then the motor 3 14 and the motor 1 12 are started, and the motor 3 14 drives the threaded rod 1 7 to rotate, and the motor 1 12 drives the threaded rod 2 11 to rotate, so that the scraper 1 23 and the scraper 2 29 are moved laterally, and the scraper 1 23 located in the groove of the conveying plate 8 moves laterally first, pushing the impurities to the grooves on both sides of the conveying plate 8. The scraper 1 23 at the gathering plate 6 moves horizontally, pushing the impurities to the drain pipe 5, so that the impurities are discharged smoothly with the water flow, thereby avoiding the situation where the impurities on the outer shell of the distribution cabinet body 1 are heavy and cannot be washed away by the water flow when falling onto the conveying plate 8 or the gathering plate 6, causing the impurities to accumulate in the groove and block the drainage channel composed of the conveying plate 8 and the gathering plate 6, thereby affecting the subsequent discharge of impurities, and the impurities are also easily attached to the surface of the distribution cabinet body 1 again. In addition, the scraper 1 23 and the scraper 2 29 will only work when the pressure value detected by the pressure sensor 27 does not change continuously. If the pressure If the pressure value detected by the force sensor 27 is always normal, the scraper 1 23 and the scraper 2 29 will not work, and the impurities can be washed away by the water flow, which saves more power resources. In addition, although the impurities can be pushed by the scraper 1 23 and the scraper 2 29 to promote the discharge of impurities, some impurities may be large in volume. When the impurities are pushed to the drain pipe 5, they may be stuck at the pipe mouth of the drain pipe 5 and cannot be discharged with the water flow, which still affects the subsequent discharge of impurities. Therefore, in order to avoid this situation, when the scraper 1 23 moves to the drain pipe 5, if the value of the pressure sensor 27 still does not decrease, it means that the impurities are stuck at the pipe mouth of the drain pipe 5, and the electric push rod 10 drives the slide plate 9 to move, so that the impurities are discharged. The collecting plate 6 is moved away from the surface of the distribution cabinet body 1, and then the second motor 13 drives the collecting plate 6 to flip and pour out the impurities in the collecting plate 6, thereby preventing the impurities from being pushed to the drain pipe 5 and getting stuck at the pipe opening of the drain pipe 5 and unable to be discharged with the water flow, which still affects the subsequent discharge of impurities. In addition, the electric push rod 10 and the second motor 13 are also started after the scraper 1 23 is activated. If the impurities can be discharged smoothly after being pushed by the scraper 1 23, the electric push rod 10 and the second motor 13 will not work, which also saves power resources. In addition, when the collecting plate 6 pours out the impurities, the impurities are in a concentrated state and away from the distribution cabinet body 1, which is beneficial to reduce the probability of impurities being attached to the distribution cabinet body 1 again due to wind force.
