TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution cabinet, and particularly relates to an outdoor power distribution cabinet for an electrical control system. BACKGROUND

[0002] The power distribution cabinet is the last stage equipment of the power distribution system, and is divided into power distribution cabinets, lighting distribution cabinets and metering cabinets. The power distribution cabinet is the general term of the motor control center. The power distribution cabinet is suitable for the occasions with relatively dispersed loads and less return circuits, and the motor control center is suitable for the occasions with concentrated loads and more return circuits. The power distribution cabinet and the motor control center distribute the electric energy of a circuit of the upper stage power distribution equipment to the nearby loads. The equipment should provide protection, monitoring and control for the loads. However, the electrical control system of a factory is generally complex, and the outdoor power distribution cabinet is often used for electric energy distribution.

[0003] The existing outdoor power distribution cabinet equipment inevitably needs to be provided with heat dissipation holes to exchange heat with the outside air, so that the dust in the outside air is easy to enter the inside of the power distribution cabinet from the heat dissipation holes. If the dust in the outside air cannot be effectively blocked from entering the inside of the power distribution cabinet, the dust will adhere to the circuit and corrode the electronic components, thereby shortening the service life of the electronic components.

[0032] For the first embodiment, please refer to... Figures 1-7 The present invention is an outdoor power distribution cabinet for an electrical control system, including a power distribution box 1, a support platform 2 fixedly connected to the bottom of the power distribution box 1, heat dissipation holes 3 on both sides of the power distribution box 1, and a cooling mechanism 5 fixedly connected to both sides of the power distribution box 1.

[0033] This distribution cabinet also features:

[0034] The dust removal mechanism 4 comprises a protective box 41, the top of the inner wall of the protective box 41 is fixedly connected with a motor 42, the output end of the motor 42 is fixedly connected with a lead screw 43, the outer surface of the lead screw 43 is threadedly connected with a clamping block 44, the inner wall of the clamping block 44 is fixedly connected with a brush 45, the upper surface of the brush 45 is fixedly connected with an adsorbing magnetic plate 46, one side of the brush 45 close to the distribution box 1 is slidably connected with a dustproof net 47, the inner wall of the dustproof net 47 is provided with a water flow groove 48, the bottom of the dustproof net 47 is fixedly connected with an inclined plate 49, and the inner wall of the inclined plate 49 is fixedly connected with a cleaning rod 401.

[0035] The cooling mechanism 5 comprises a cooling box 51, the upper portion of the outer surface of the cooling box 51 is fixedly connected with a water inlet pipe 52, and the bottom of the inner wall of the cooling box 51 is fixedly connected with a bend pipe 53.

[0036] The inner wall of the cooling box 51 is fixedly connected with a water flow box 55, the inner wall of the water flow box 55 is slidably connected with a water shielding plate 56, the upper surface of the water shielding plate 56 is fixedly connected with a pull rope 57, the outer surface of the pull rope 57 is slidably connected with a guide pipe 58, and one end of the pull rope 57 away from the water shielding plate 56 is fixedly connected with a moving magnetic plate 59.

[0037] The side, close to the distribution box 1, of the protective box 41 is fixedly connected with the outer surface of the distribution box 1, the side, away from the brush 45, of the dustproof net 47 is fixedly connected with the outer surface of the distribution box 1, and the inner wall of the dust removal mechanism 4 is fixedly connected with an opening and closing mechanism 6.

[0038] The side, away from the brush 45, of the cooling box 51 is fixedly connected with the outer surface of the distribution box 1, the outer surface of the water inlet pipe 52 is fixedly connected with the inner wall of the protective box 41, the lower surface of the bend pipe 53 is fixedly connected with the inner wall of the support table 2, and one end of the water outlet pipe 54, away from the bend pipe 53, penetrates through the inner wall of the support table 2.

[0039] The outer surface of the water flow box 55 is fixedly connected with the inner wall of the dustproof net 47, the outer surface of the guide pipe 58 is fixedly connected with the inner wall of the cooling box 51, and the moving magnetic plate 59 is arranged above the adsorbing magnetic plate 46.

[0040] In use, first distribution box 1 is placed in the middle of the left and right protection boxes 41, the upper surface of the support table 2 supports the bottom of the distribution box 1, and dust screen 47 is provided to prevent dust from the outside from entering the interior of the distribution box 1 through the heat dissipation holes 3. The rotation of the lead screw 43 can be driven by the motor 42, and the lead screw 43 can drive the clamping block 44 and the up-and-down movement of the brush 45 in rotation. The dust on the outer surface of the dust screen 47 can be cleaned by the brush 45 in the up-and-down movement. When the brush 45 descends to the position of the cleaning rod 401, the elastic bristles on the brush 45 will contact the cleaning rod 401. Relative to the movement of the brush 45, the cleaning rod 401 will move upward from the lower surface of the elastic bristles and fall the dust attached to the surface of the brush 45. When the elastic brush 45 moves to the lowest position and moves upward again to contact the cleaning rod 401, the elastic brush 45 can be cleaned, and the falling dust slides along the inclined plate 49 to the outside. Since the cleaning rod 401 is relatively thin, the outer surface will not attach too much dust.

[0041] When the power distribution box 1 is cooled, the staff can pour water from the water inlet pipe 52 into the inside of the cooling box 51, the water inlet pipe 52 is a one-way pipe, and the water in the inside of the cooling box 51 also enters the inside of the elbow pipe 53, so that both sides of the power distribution box 1 are wrapped by the cooling box 51, and the cooling box 51 can cool both sides of the power distribution box 1, and the elbow pipe 53 can cool the bottom of the power distribution box 1, and the elbow pipe 53 is arranged in a surrounding type, so as to increase the contact area with the bottom of the power distribution cabinet and effectively cool. When winter comes, to prevent the water in the elbow pipe 53 from freezing due to cold weather and causing damage to the elbow pipe 53, the water in the elbow pipe 53 can be discharged in advance through the water outlet pipe 54, and the elbow pipe 53 does not need to cool the bottom of the power distribution box 1 in winter. The water outlet pipe 54 can be opened when needed, and the water outlet pipe 54 is closed when the elbow pipe 53 cools the bottom of the power distribution box 1, and the water cannot flow out. Because the inside of the cooling box 51 is full of water, the water baffle 56 slides downward along the inner wall of the water flow tank 55 under the extrusion of the water and the gravity of the water baffle 56 by a certain distance, until the upper surface of the moving magnetic plate 59 abuts against the bottom of the guide pipe 58, and the water baffle 56 cannot slide any more. Because the brush 45 moves up and down along the surface of the dust screen 47, the brush 45 can drive the top adsorbing magnetic plate 46 to move, and when the adsorbing magnetic plate 46 moves upward and approaches the moving magnetic plate 59, the adsorbing magnetic plate 46 can attract the moving magnetic plate 59 to slide downward, and the two magnetic plates have strong enough magnetic force to be attracted. When the moving magnetic plate 59 moves downward, the water baffle 56 is driven by the pull rope 57 to slide upward along the inner wall of the water flow tank 55, until the two outer surfaces near the bottom of the water baffle 56 open a gap with the inner wall of the water flow tank 55, so that the water in the inside of the cooling box 51 can enter the inside of the water flow tank 55 through the gap between the water baffle 56 and the water flow tank 55, and then continue to slide down the inner wall of the water flow tank 55 to the inner wall of the dust screen 47 to clean the surface of the dust screen 47 close to the power distribution cabinet. The water flows down from top to bottom along the surface of the dust screen 47, flows down the upper surface of the inclined plate 49 through the water flow tank 48, and then flows down the inclined surface of the inclined plate 49 to the outside, and can also clean the surface of the inclined plate 49, so as to prevent too much dust from remaining on the surface of the inclined plate 49. When the brush 45 drives the moving magnetic plate 59 to move downward, the distance between the moving magnetic plate 59 and the adsorbing magnetic plate 46 becomes larger and larger, and the adsorbing magnetic plate 46 cannot feel the attraction, and then returns to the original position under the gravity of the water baffle 56 and the pressure of the water on the water baffle 56.

[0042] The second embodiment, please refer to Figures 1-9The utility model provides an outdoor distribution cabinet for electrical control system, and the opening and closing mechanism 6 includes telescopic link 61, the output end of telescopic link 61 is fixedly connected with slide rope 62, the outer surface of slide rope 62 is fixedly connected with sleeve block 63, the end of slide rope 62 away from telescopic link 61 is fixedly connected with folding plate 64, and the upper surface of opening and closing mechanism 6 is fixedly connected with cleaning mechanism 7.

[0043] The outer surface of telescopic link 61 is fixedly connected with the inner wall of protection box 41, sleeve block 63 is slidably connected with the inner wall of protection box 41, and telescopic link 61 is symmetrically arranged on the two sides of folding plate 64.

[0044] When rain comes or the temperature is low in winter, rainwater can enter the inside of the distribution cabinet through the heat dissipation hole 3, and cold gas can also enter the inside of the distribution cabinet, both of which can cause damage to the elements of the distribution cabinet. Therefore, a baffle is needed to block the entry of rainwater or cold gas. Telescopic link 61 is started and retracted, which can drive the movement of slide rope 62 and sleeve block 63, sleeve block 63 slides downward along the inner wall of protection box 41, and the end of slide rope 62 close to folding plate 64 can drive the elongation of folding plate 64, so that the top end of folding plate 64 gradually contacts the surface of the upper protection box 41, blocks the notch on one side of protection box 41, avoids the entry of small rainwater through the notch on one side of protection box 41 and the heat dissipation hole 3 under the blowing of the wind, and also avoids the entry of cold gas.

[0045] The cleaning mechanism 7 includes a connecting spring 71, the bottom end of the connecting spring 71 is fixedly connected with a limiting plate 72, the top end of the connecting spring 71 is fixedly connected with a sliding plate 73, and the side of the sliding plate 73 close to the connecting spring 71 is fixedly connected with a connecting rope 74.

[0046] The lower surface of the limiting plate 72 is fixedly connected with the upper surface of the distribution box 1, the lower surface of the sliding plate 73 is slidably connected with the upper surface of the distribution box 1, and the outer surface of the connecting rope 74 is slidably connected with the inner wall of the distribution box 1. In the process of retraction of telescopic link 61, telescopic link 61 can also drive the movement of connecting rope 74 through sleeve block 63, connecting rope 74 pulls the sliding plate 73 to slide downward along the inclined upper surface of the distribution cabinet, which can scrape off the garbage and bird droppings on the surface of the distribution cabinet, and improve the appearance of the distribution cabinet. The sliding plate 73 also extrudes the connecting spring 71 in the process of inclined sliding along the surface, and the limiting plates 72 on both sides of the sliding plate 73 limit the sliding of the sliding plate 73.

[0047] The specific working process is as follows:

[0048] First, the distribution box 1 is placed in the middle of the left and right protection boxes 41, the upper surface of the support table 2 supports the bottom of the distribution box 1, and the dust screen 47 is provided to avoid dust from the outside entering the inside of the distribution box 1 through the heat dissipation hole 3. The rotation of the lead screw 43 can be driven by the motor 42, and the lead screw 43 can drive the clamping block 44 and the up-down movement of the brush 45 in the rotation, and the dust on the outer surface of the dust screen 47 can be cleaned down in the up-down movement of the brush 45, when the brush 45 descends to the position of the cleaning rod 401, the elastic bristles on the brush 45 will contact the cleaning rod 401, relative to the movement of the brush 45, the cleaning rod 401 will move upward from the lower surface of the elastic bristles and fall off the dust attached to the surface of the brush 45, when the elastic brush 45 moves to the lowest position and moves upward again to contact the cleaning rod 401, the elastic brush 45 can be cleaned, and the falling dust slides along the inclined plate 49 to the outside.

[0049] When the power distribution cabinet is cooled, the staff can pour water from the water inlet pipe 52 into the inside of the cooling box 51, the water inlet pipe 52 is a one-way pipe, and the water in the cooling box 51 also enters the inside of the elbow pipe 53, so that both sides of the power distribution cabinet 1 are wrapped by the cooling box 51, and the cooling box 51 can cool both sides of the power distribution cabinet, and the elbow pipe 53 can cool the bottom of the power distribution cabinet, and the elbow pipe 53 is arranged in a surrounding type, so as to increase the contact area with the bottom of the power distribution cabinet and effectively cool. Because the inside of the cooling box 51 is full of water, the water plate 56 slides downward along the inner wall of the water tank 55 under the extrusion of the water and the gravity of the water plate 56, until the upper surface of the moving magnetic plate 59 abuts against the bottom of the guide pipe 58, and the water plate 56 cannot slide again. Because the brush 45 moves up and down along the surface of the dust screen 47, the brush 45 can drive the movement of the top adsorbing magnetic plate 46, and when the adsorbing magnetic plate 46 moves upward and approaches the moving magnetic plate 59, the moving magnetic plate 59 is adsorbed and slides downward, and the two magnetic plates have sufficient magnetic force and can be adsorbed. When the moving magnetic plate 59 moves downward, the water plate 56 is driven to slide upward along the inner wall of the water tank 55 through the pull rope 57, until the two outer surfaces near the bottom of the water plate 56 are opened with a gap on the inner wall of the water tank 55, so that the water in the cooling box 51 can enter the inside of the water tank 55 through the gap between the water plate 56 and the water tank 55, and then continue to slide down to the inner wall of the dust screen 47, and clean the side of the dust screen 47 close to the power distribution cabinet. The water flows from top to bottom along the surface of the dust screen 47, flows through the water tank 48 to the upper surface of the inclined plate 49, and then flows along the inclined surface of the inclined plate 49 to the outside, and can also clean the surface of the inclined plate 49, so as to prevent too much dust from remaining on the surface of the inclined plate 49. When the brush 45 drives the moving magnetic plate 59 to move downward, the distance between the moving magnetic plate 59 and the adsorbing magnetic plate 46 becomes larger and larger, and the adsorbing magnetic plate 46 cannot feel the suction force, and returns to the original position again under the gravity of the water plate 56 and the pressure of the water on the water plate 56.

[0050] When the rain weather comes or the temperature is low in winter, rain may enter the inside of the power distribution cabinet through the heat dissipation hole 3, and cold gas may also enter the inside of the power distribution cabinet, both of which will cause damage to the elements of the power distribution cabinet. Therefore, the baffle is needed to block the entry of rain or cold gas. The telescopic rod 61 is started and retracted, which can drive the movement of the sliding rope 62 and the sleeve block 63, the sleeve block 63 slides downward along the inner wall of the protection box 41, and the end of the sliding rope 62 close to the folding plate 64 can drive the elongation of the folding plate 64, so that the top end of the folding plate 64 gradually contacts the surface of the upper protection box 41, blocks the gap opened on one side of the protection box 41, and avoids the entry of small rain through the gap and the heat dissipation hole 3 into the inside of the power distribution cabinet, and also avoids the entry of cold gas.

[0051] When it is needed to clean the upper surface of the power distribution cabinet, the telescopic rod 61 is retracted, and the sleeve block 63 can drive the movement of the connecting rope 74, the connecting rope 74 pulls the sliding plate 73 to slide downward along the inclined surface of the power distribution cabinet, which can scrape off the garbage and bird droppings on the surface of the power distribution cabinet. The sliding plate 73 also extrudes the connecting spring 71 during the inclined sliding on the surface, and the limiting plates 72 on both sides of the sliding plate 73 limit the sliding of the sliding plate 73.

[0052] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art and related fields without creative labor should belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if not specially described and limited, are implemented according to the conventional means in the art.
