Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of power distribution cabinets, and in particular, to a combined rainproof power distribution cabinet and a method of using the same. Background Art

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets. They are the final equipment of the distribution system. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] Most of the existing distribution cabinets are integrated fixed structures, which take up a large space during transportation and storage. At the same time, different models of distribution cabinets need to be replaced to meet different electrical component usage requirements. The same distribution cabinet is difficult to adapt to diverse installation requirements. In addition, current distribution cabinets generally use an angled cabinet top to protect the cabinet body from rain. The rainproof area is small and the protection effect is relatively limited. Rainwater can still enter the interior of the cabinet through the gap between the cabinet door and the cabinet body. Especially when the distribution cabinet is opened on rainy days, it is easy to cause overload or short circuit of the electrical components in the distribution cabinet. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a combined rainproof distribution cabinet and a method of use, which are used to solve the technical problems in the prior art that the distribution cabinet is an integral structure, is inconvenient to transport and store, and has a relatively limited rainproof effect.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a combined rainproof power distribution cabinet, comprising a base and further comprising: Top cover; Two mounting slots are provided, and the two mounting slots are fixedly connected to the bottom end of the top cover and the top end of the base respectively; A splicing side wall is provided, wherein a plurality of the splicing side walls are provided, the splicing side walls are a telescopic structure, the splicing side walls are installed inside the mounting groove, and the splicing side walls include: A fixing plate, two of which are provided, and the fixing plates and the mounting slots are in sliding fit; A foldable expansion piece, wherein the foldable expansion piece is fixedly connected between the two fixed plates; The splicing cabinet door is a telescopic structure, and the splicing cabinet door is installed inside the installation groove. The splicing cabinet door includes: Corner posts, two of which are provided, the corner posts and the mounting slots are in sliding fit, the corner posts are fixedly connected to the limiting blocks, and the fixing plate is provided with limiting grooves matching the limiting blocks; A door frame, wherein the door frame is connected to the corner column via the folding expansion piece, and the door frame and the mounting groove are in sliding fit; a door panel hinged to the door frame; A limiting rod is slidably mounted on the mounting groove, and limiting holes matching the limiting rod are provided on the fixing plate and the door frame, for fixing the spliced ​​side wall and the spliced ​​cabinet door inside the mounting groove; A rain cover is detachably mounted on the top cover via a connecting assembly, wherein the connecting assembly comprises: Support bases, the support bases being fixedly connected to both sides of the top cover, the support bases being in contact with the inner bottom wall of the rainproof cover; An insertion rod is slidably mounted on the rainproof cover, and a socket matching the insertion rod is provided on the support seat; A side protective plate is detachably connected to the bottom of the rain cover.

[0006] In order to improve the stability of the rainproof cover, the support seat is connected to a locking plate through a compression spring, and the locking plate is fixedly connected to a locking rod. The support seat and the insertion rod are both provided with locking holes that match the locking rod.

[0007] In order to prevent rainwater from entering the interior of the power distribution cabinet, drainage holes are provided on the base and at the bottom of the mounting slot on the base.

[0008] In order to further reduce the ingress of rainwater, a sealing gasket is fixedly connected to the edge of the fixing plate.

[0009] In order to reduce the impact of rainwater on the opening door panel, the front end of the rainproof cover is fixedly connected to a water retaining groove, and rain holes are opened at both ends of the water retaining groove.

[0010] A method for using a combined rainproof power distribution cabinet, using the above-mentioned combined rainproof power distribution cabinet, includes the following steps: S1. Select a base, top cover, and rain cover of appropriate sizes based on installation requirements. Install the fixing plate, corner posts, and door frame inside the installation slots. Adjust the position of the fixing plate by folding the expansion strips to connect the multiple spliced ​​side walls end to end. Insert the limiting rods into the limiting holes to secure the fixing plate and door frame. S2. Install the top cover on the top of the spliced ​​side walls, corner columns and door frames, insert the limit rods into the limit holes to fix the top cover, and install the side protective plates on the rain cover; S3. When it rains, the rainproof cover protects the top of the combined rainproof distribution cabinet, and the side protective plates protect the side walls of the combined rainproof distribution cabinet from rain. Rainwater slides along the rainproof cover to the inside of the water retaining groove and falls through the raindrop holes. Rainwater on the surface of the spliced ​​side wall enters the inside of the installation groove and is discharged through the drainage holes.

[0011] The beneficial effects of the embodiments of the present invention are: 1. In the present invention, by folding and expanding the expansion and contraction of the expansion and contraction sheets and selecting an appropriate number of splicing side walls, and selecting a base and a top cover of appropriate sizes, power distribution cabinets of different sizes can be assembled to meet different installation requirements. The power distribution cabinet is spliced ​​by plate-like components such as a base, splicing side walls and splicing cabinet doors. The plate-like components are stacked during transportation and storage, which takes up less space and is convenient for transportation and storage.

[0012] 2. In the present invention, the top of the distribution cabinet is protected by a rainproof cover and a top cover, and the surrounding areas of the distribution cabinet are protected by side protective plates to reduce the entry of rainwater. Rainwater on the spliced ​​side walls and the spliced ​​cabinet doors partially falls into the interior of the installation groove and is discharged through the drainage holes. The installation groove blocks the rainwater, reducing the entry of rainwater into the interior of the distribution cabinet, thereby reducing overload or short circuit of electrical components.

[0021] like Figures 1 to 9 As shown, it shows a combined rainproof distribution cabinet in one embodiment of the present invention, including a base 1, a top cover 2, a mounting groove 4, spliced ​​side walls, a spliced ​​cabinet door, a limit rod 5, a rainproof cover 6 and a side protective plate 7. A support frame 3 is fixedly installed at the lower end of the base 1, which allows a certain gap to exist between the distribution cabinet and the ground, thereby reducing corrosion on the bottom of the distribution cabinet caused by rainwater accumulation.

[0022] like Figures 1 to 6 As shown, there are two mounting grooves 4, which are respectively fixedly connected to the bottom end of the top cover 2 and the top end of the base 1. In order to prevent rainwater from entering the interior of the distribution cabinet, drainage holes are provided on the base 1 and at the bottom of the mounting groove 4 located on the base 1. The mounting groove 4 is square, and the sizes of the mounting groove 4, the base 1 and the top cover 2 are adapted and slightly smaller than the base 1 and the top cover 2.

[0023] like Figures 1 to 4As shown, the splicing side walls are provided with multiple, and the splicing side walls are of a telescopic structure. The splicing side walls are installed inside the mounting groove 4, and the splicing side walls include a fixed plate 101 and a folded telescopic piece 102. The fixed plates 101 are provided with two, and the fixed plates 101 and the mounting groove 4 are in sliding cooperation. The folded telescopic piece 102 is fixedly connected between the two fixed plates 101, and the edge of the fixed plate 101 is fixedly connected with a sealing gasket 103. The distance between the two fixed plates 101 can be adjusted by the expansion and contraction of the folded telescopic piece 102, that is, the overall size of the splicing side wall is adjusted to a certain extent. By selecting an appropriate number of splicing side walls and adjusting the size of a single splicing side wall, the splicing side walls can be adapted to bases 1 of different sizes, that is, mounting grooves 4 of different sizes. Multiple splicing side walls are installed tightly against each other inside the mounting groove 4, and can be spliced ​​into a cabinet closed on three sides, and electrical components can be installed inside the cabinet.

[0024] like Figures 1 to 5 As shown, the spliced ​​cabinet door is a telescopic structure, and the spliced ​​cabinet door is installed inside the installation groove 4. The spliced ​​cabinet door includes a corner post 201, a door frame 202 and a door panel 203. There are two corner posts 201, and the corner posts 201 and the installation groove 4 are in sliding cooperation. The corner posts 201 are fixedly connected to the limiting block 204. The fixing plate 101 is provided with a limiting groove that matches the limiting block 204. The door frame 202 is connected to the folding expansion piece 102 and the door panel 203. The corner posts 201 are connected, the door frame 202 and the mounting groove 4 are in sliding cooperation, and the door panel 203 is hinged on the door frame 202. The direction of the spliced ​​cabinet door is the front side of the distribution cabinet. The two corner posts 201 are located at the two ends of the front side of the distribution cabinet, and the door frame 202 is located in the middle position of the front side of the mounting groove 4. The limit block 204 is inserted into the interior of the limit groove so that the corner post 201 and the fixing plate 101 are tightly attached to ensure the stability of the two corner positions of the corner post 201 on the front side of the mounting groove 4.

[0025] The limiting rod 5 is slidably installed on the mounting groove 4, and the fixing plate 101 and the door frame 202 are both provided with limiting holes matching the limiting rod 5, which are used to fix the spliced ​​side wall and the spliced ​​cabinet door to the inside of the mounting groove 4. There is a large sliding damping between the limiting rod 5 and the limiting hole. By inserting the limiting rod 5 into the inside of the limiting hole, the fixing plate 101 and the door frame 202 can be fixed to a specific position of the mounting groove 4, ensuring a close fit between the spliced ​​side wall and the spliced ​​cabinet door. At the same time, the sealing gasket 103 is used to further improve the sealing between the spliced ​​side wall and the spliced ​​cabinet door, reducing the entry of rainwater. There is a certain gap between the folding expansion plate 102 and the inner wall of the mounting groove 4, and part of the rainwater enters the interior of the mounting groove 4 through the gap. The rainwater in the mounting groove 4 can be discharged in time through the drainage hole to avoid affecting the electrical components inside the distribution cabinet.

[0026] like Figures 1 to 9 As shown, the rain cover 6 is detachably arranged on the top cover 2 through a connecting assembly, and the connecting assembly includes a support seat 301 and a plug rod 302. The support seat 301 is fixedly connected to both sides of the top cover 2, and the support seat 301 is in contact with the inner bottom wall of the rain cover 6. The plug rod 302 is slidably installed on the rain cover 6. The support seat 301 is provided with a socket that matches the plug rod 302. The support seat 301 is connected to a locking plate 304 through a compression spring 303. The locking plate 304 is fixedly connected to a locking rod 305. Both the support seat 301 and the plug rod 302 are provided with a socket. There is a locking hole that matches the locking rod 305, and the side protective plate 7 is detachably connected to the bottom of the rain cover 6 through a hook. The front end of the rain cover 6 is fixedly connected to a water retaining groove 8, and rain holes are opened at both ends of the water retaining groove 8. The rain cover 6 is a herringbone shape, and the front and rear sides of the rain cover 6 are the sides with lower height. When it rains, rainwater can fall along the rain cover 6 in time, and the rainwater on the front side falls into the inside of the water retaining groove 8 and falls through the rain holes on the left and right sides of the water retaining groove 8, reducing the rain on the front side of the distribution cabinet, thereby facilitating the reduction of rainwater from entering when the door panel 203 is opened and closed. When the cam 305 is in the closed position, the cam 306 is in the closed position, and the cam 307 is in the closed position, so that the cam 307 is in the closed position and the cam 307 is out of the closed position. When part of the power distribution cabinet is damaged, the entire power distribution cabinet is replaced, which reduces the replacement cost during use. A plurality of hanging holes are provided on the rain cover 6, and the side protective plates 7 are hung on the hanging holes by spring hooks, so that the side protective plates 7 can be easily disassembled and assembled. At the same time, the spring hooks can play a hinged role, so that the side protective plates 7, especially the side protective plates 7 on the front side, can be rotated. The side protective plates 7 can be rotated upward to open and close the door panel 203 freely, and the front side of the rain cover 6 protrudes a certain distance from the door panel 203, that is, there is a certain distance between the side protective plates 7 on the front side and the door panel 203, which reduces the obstruction to the opening and closing of the door panel 203.

[0027] Another embodiment of the present invention discloses a method for using a combined rainproof power distribution cabinet, which uses the above-mentioned combined rainproof power distribution cabinet and includes the following steps: S1. Select the appropriate sizes of base 1, top cover 2, and rain cover 6 according to installation requirements. Install the fixing plate 101, corner post 201, and door frame 202 inside the installation slot 4. Adjust the position of the fixing plate 101 by folding the expansion strip 102 to connect the multiple spliced ​​side walls end to end. Insert the limiting rod 5 into the limiting hole to secure the fixing plate 101 and door frame 202. S2. Install the top cover 2 on the top of the spliced ​​side walls, corner posts 201 and door frame 202, insert the limiting rods 5 into the limiting holes to fix the top cover 2, and install the side protection plates 7 on the rain cover 6; S3. When it rains, the rainproof cover 6 protects the top of the combined rainproof distribution cabinet, and the side protective plate 7 protects the side wall of the combined rainproof distribution cabinet from rain. Rainwater slides along the rainproof cover 6 to the inside of the water retaining groove 8 and falls through the raindrop hole. The rainwater on the surface of the spliced ​​side wall enters the inside of the installation groove 4 and is discharged through the drainage hole.
