Description

Technical Field

[0001] This invention relates to the field of outdoor power distribution cabinet technology, and more particularly to a waterproof power distribution cabinet for outdoor use. Background Technology

[0002] In power transmission and distribution systems, switchboards, as one of the core pieces of equipment, undertake key functions such as power distribution, circuit protection, and equipment control. Their operational stability directly affects the overall reliability of the power system. With the advancement of urbanization, the booming development of the new energy industry (such as distributed photovoltaic power stations, outdoor charging pile clusters, and energy storage power stations), and the deepening of rural power grid transformation, the outdoor application scenarios of new power equipment (such as photovoltaic inverters, energy storage converters, charging pile modules, and intelligent monitoring terminals) have increased significantly. A large number of switchboards need to be installed in outdoor environments to match these new power equipment, such as next to photovoltaic power station arrays, new energy vehicle charging stations, energy storage sites in industrial parks, and intelligent transmission line nodes in remote areas.

[0003] For example, an existing patent (application number: CN202311342296.0) discloses an outdoor waterproof power distribution cabinet. Although the outdoor waterproof power distribution cabinet can seal the heat dissipation holes on the sides and bottom in rainy weather, it relies on a large number of gears and racks and other transmission components to drive the sealing plate during sealing. The structure is complex and the transmission components are directly exposed, making them easy to be stuck by fallen leaves and other debris, which seriously affects the reliability of the waterproof seal. Moreover, the transmission components require at least two motors to drive in coordination, which increases manufacturing costs and energy consumption. In addition, when the seal is released, the two motors need to be controlled to operate in reverse, making the operation process cumbersome and the response efficiency low. Summary of the Invention

[0004] This invention relates to a waterproof distribution cabinet for outdoor use, which solves the problems of existing outdoor waterproof distribution cabinets. Although they can seal the side and bottom heat dissipation holes in rainy weather, the sealing process relies on a large number of transmission components such as gears and racks, which makes the structure complex and easily jammed by fallen leaves and other debris, seriously affecting the reliability of the waterproof seal. In addition, when the seal is released, two motors need to be controlled to operate in reverse, which makes the operation process cumbersome and the response efficiency low.

[0005] In a first aspect, the present invention provides a waterproof power distribution cabinet for outdoor use, specifically comprising: a power distribution cabinet body, wherein support slide columns are fixedly connected to the four corners of the bottom surface of the power distribution cabinet body, and a support block is provided at the lower end of each support slide column; a driving component is provided outside the support slide columns at the bottom of the power distribution cabinet body, and side sealing components are connected to the upper left and right sides of the driving component, and a bottom sealing plate is installed on the upper middle side of the driving component; a driving motor is installed inside the rear side of the power distribution cabinet body, and automatic locking mechanisms are installed on the left and right sides of the driving motor inside the rear side of the power distribution cabinet body, and an automatic unlocking mechanism is provided at the bottom of each automatic locking mechanism.

[0006] Furthermore, a cabinet door is rotatably connected to the front side of the main body of the power distribution cabinet via a pivot, and a controller is installed on the cabinet door. A rain sensor is installed on the top of the main body of the power distribution cabinet.

[0007] Furthermore, the driving component includes a lifting frame, which is slidably connected to the outside of the support column. Lower U-shaped connecting plates are fixedly connected to the upper left and right sides of the lifting frame. A lever is slidably connected inside each lower U-shaped connecting plate. A support frame fixed to the bottom of the main body of the distribution cabinet is rotatably connected to the middle of each lever via a rotating shaft. An upper U-shaped connecting plate is slidably connected to the upper end of each lever. A driving plate is fixedly connected to the top of each upper U-shaped connecting plate. A slide rail fixed to the side of the main body of the distribution cabinet is slidably connected to each driving plate.

[0008] Furthermore, the lever is provided with an upper sliding column and a lower sliding column at its upper and lower ends, respectively. Both the lower U-shaped connecting plate and the upper U-shaped connecting plate are provided with strip-shaped sliding grooves. The strip-shaped sliding groove on the lower U-shaped connecting plate is slidably connected to the lower sliding column, and the strip-shaped sliding groove on the upper U-shaped connecting plate is slidably connected to the upper sliding column. The lever is located inside the lower U-shaped connecting plate and the upper U-shaped connecting plate.

[0009] Furthermore, a limit rod is fixedly connected to the rear side of the upper end face of the lifting frame, and a guide sleeve fixed to the rear end face of the main body of the power distribution cabinet is slidably connected to the outside of the limit rod. A rectangular socket is opened on the rear end face of the limit rod.

[0010] Furthermore, guide cylinders are provided at the four corners of the upper surface of the lifting frame, and the guide cylinders are slidably connected to the support cylinders, and springs are sleeved on the outside of the guide cylinders and the support cylinders.

[0011] Furthermore, the side sealing assembly includes a guide rail, which is installed on the side of the main body of the distribution cabinet. A connecting rod is slidably connected to the inner side of the guide rail, and a side sealing plate is fixedly connected to the connecting rod. The lower end of the connecting rod is fixedly connected to the upper surface of the drive plate. A frame-shaped sealing gasket is provided on the upper surface of the bottom sealing plate.

[0012] Furthermore, the shaft of the drive motor passes through the rear side wall of the main body of the power distribution cabinet, and a reel is fixedly connected to the rear end of the drive motor shaft. A pulling rope is wound on the reel, and the lower end of the pulling rope is fixedly connected to the rear side of the upper end face of the lifting frame.

[0013] Furthermore, the automatic locking mechanism includes a rectangular sliding shell, which is fixedly connected to the rear side of the main body of the distribution cabinet. A rectangular slider is slidably connected inside the rectangular sliding shell. A plug-in block that penetrates the rectangular sliding shell and the rear side wall of the main body of the distribution cabinet is fixedly connected to the rear end face of the rectangular slider. The lower edge of the rear end of the plug-in block is chamfered. A pull rod that penetrates the front side wall of the rectangular sliding shell is fixedly connected to the front end face of the rectangular slider. A spring is sleeved on the outside of the pull rod inside the rectangular sliding shell. When the automatic locking mechanism is in the locking limit state, the rear end of the plug-in block is inserted into the rectangular plug, and at this time, both the side sealing plate and the bottom sealing plate are in a sealed state.

[0014] Furthermore, the automatic unlocking mechanism includes a push-pull electromagnet, which is installed inside the rear side of the main body of the distribution cabinet and located at the bottom of the automatic locking mechanism. A pull rope is fixedly connected to the front end of the push-pull rod on the push-pull electromagnet, and the other end of the pull rope is fixedly connected to the front end of the pull rod. A pulley is slidably connected to the outside of the pull rope. The pulley is installed inside the rear side of the main body of the distribution cabinet through a bracket. A U-shaped limiting plate is fixedly connected to the rear end of the bracket. An arc-shaped notch is opened on the rear side of the U-shaped limiting plate, and the arc-shaped notch is located outside the pulley. The pull rope is located inside the U-shaped limiting plate.

[0015] This invention provides a waterproof power distribution cabinet for outdoor use, which has the following advantages: First, through the design of the drive components, this invention allows for the simultaneous driving of the bottom sealing plate and the side sealing plate to achieve sealing when sealing and waterproofing operations are required, relying solely on the linkage of the lower U-shaped connecting plate, lever, upper U-shaped connecting plate, and support frame. This significantly simplifies the transmission structure, and even if debris such as fallen leaves falls onto these structures, jamming is less likely to occur, significantly improving the reliability and environmental adaptability of the waterproof seal. At the same time, the entire sealing process requires only one drive motor, effectively reducing manufacturing costs and operating energy consumption.

[0016] Secondly, through the coordinated design of the automatic locking mechanism, the limiting rod, and the rectangular socket, after the bottom sealing plate completes the sealing of the bottom of the distribution cabinet body, the rectangular slider drives the plug block to move rapidly backward under the action of the spring force outside the pulling rod, so that the rear end of the plug block is automatically inserted into the rectangular socket. This action realizes the reliable locking of the limiting rod on the rear side of the distribution cabinet body, thereby significantly enhancing the stability and anti-interference ability of the bottom sealing plate and the side sealing plate in the sealed state.

[0017] Third, through the design of the automatic unlocking mechanism, when the seal needs to be released, the present invention only requires energizing the push-pull electromagnet, causing the push-pull rod on the electromagnet to move the lower end of the pull rope backward, which in turn pulls the pull rod, rectangular slider and plug block forward, so that the rear end of the plug block is pulled out of the rectangular socket, and the limit rod is released from locking. Subsequently, under the elastic force of the springs outside the guide slide and the support slide column, the lifting frame moves the bottom sealing plate down to reset, and at the same time the side sealing plates on both sides move up to return to their positions, quickly releasing the seal. This process does not require controlling the motor to operate in reverse, which significantly simplifies the operation process and improves the response efficiency.

[0018] Fourth, the present invention has an arc-shaped notch on the rear side of the U-shaped limiting plate, and the arc-shaped notch is located outside the pulley, while the pull rope is located inside the U-shaped limiting plate. This can effectively guide and limit the pull rope, prevent the pull rope from detaching from the pulley, and significantly improve the reliability of the automatic unlocking mechanism during use.

[0023] Example 1: Please refer to Figures 1 to 10 : This invention proposes a waterproof distribution cabinet for outdoor use, comprising: a distribution cabinet body 1, with heat dissipation holes on the left and right sides and the center of the bottom surface of the distribution cabinet body 1; support columns 101 fixedly connected to the four corners of the bottom surface of the distribution cabinet body 1, and a support block 102 provided at the lower end of each support column 101; a rubber buffer pad can be provided on the upper surface of the support block 102 to buffer the impact force when the lifting frame 201 moves downward; a driving component 2 is provided on the outside of the support column 101 at the bottom of the distribution cabinet body 1, and side sealing components 3 are connected to the left and right sides of the upper part of the driving component 2; and a bottom sealing plate 4 is installed on the middle side of the upper part of the driving component 2; the distribution... A drive motor 5 is installed on the rear side inside the cabinet body 1, and automatic locking mechanisms 6 are installed on the left and right sides of the drive motor 5 on the rear side inside the cabinet body 1. Each automatic locking mechanism 6 has an automatic unlocking mechanism 7 at its bottom. Through the design of the drive component 2, when sealing and waterproofing operations are required, the bottom sealing plate 4 and the side sealing plate 302 can be synchronously driven to achieve sealing by relying on the linkage of the lower U-shaped connecting plate 203, lever 204, upper U-shaped connecting plate 205 and support frame 2011. This greatly simplifies the transmission structure, and even if fallen leaves or other debris fall on these structures, they are not easy to get stuck, which greatly improves the reliability of waterproof sealing.

[0024] The front of the main body 1 of the power distribution cabinet is connected to a cabinet door via a pivot, and a controller 103 is installed on the cabinet door. A rain sensor 104 is installed on the top of the main body 1 of the power distribution cabinet to detect whether it is raining outdoors.

[0025] The drive assembly 2 includes a lifting frame 201, which is slidably connected to the outside of the support column 101. The upper left and right sides of the lifting frame 201 are fixedly connected to a lower U-shaped connecting plate 203. A lever 204 is slidably connected inside each lower U-shaped connecting plate 203. The middle of each lever 204 is rotatably connected to a support frame 2011 fixed to the bottom of the main body 1 of the power distribution cabinet via a rotating shaft. An upper U-shaped connecting plate 205 is slidably connected to the upper end of each lever 204. A drive plate 206 is fixedly connected to the top of each upper U-shaped connecting plate 205. A slide rail 207 fixed to the side of the main body 1 of the power distribution cabinet is slidably connected to each drive plate 206. Through the setting of the drive assembly 2, the bottom sealing plate 4 and the side sealing plate 302 can be driven synchronously to achieve sealing.

[0026] The lever 204 has an upper sliding column 2012 and a lower sliding column 2013 at its upper and lower ends, respectively. Both the lower U-shaped connecting plate 203 and the upper U-shaped connecting plate 205 have strip-shaped sliding grooves. The strip-shaped sliding groove on the lower U-shaped connecting plate 203 is slidably connected to the lower sliding column 2013, and the strip-shaped sliding groove on the upper U-shaped connecting plate 205 is slidably connected to the upper sliding column 2012. The lever 204 is located inside the lower U-shaped connecting plate 203 and the upper U-shaped connecting plate 205, so that the lever 204 can also be effectively limited in the front and rear directions.

[0027] A limit rod 208 is fixedly connected to the rear side of the upper end face of the lifting frame 201, and a guide sleeve 2010 fixed to the rear end face of the main body 1 of the power distribution cabinet is slidably connected to the limit rod 208. A rectangular socket 209 is opened on the rear end face of the limit rod 208 for plugging into the plug block 603.

[0028] Guide cylinders 202 are provided at the four corners of the upper surface of the lifting frame 201, and the guide cylinders 202 are slidably connected to the support cylinders 101. Springs are sleeved on the outside of the guide cylinders 202 and the support cylinders 101, so that the lifting frame 201 moves down and resets more quickly.

[0029] The side sealing assembly 3 includes a guide rail 301, which is installed on the side of the main body 1 of the power distribution cabinet. A connecting rod 303 is slidably connected to the inner side of the guide rail 301, and a side sealing plate 302 is fixedly connected to the connecting rod 303. The lower end of the connecting rod 303 is fixedly connected to the upper end face of the drive plate 206. A frame-shaped sealing gasket 401 is provided on the upper end face of the bottom sealing plate 4 to improve the sealing and waterproofing effect of the bottom sealing plate 4 on the heat dissipation holes at the bottom of the main body 1 of the power distribution cabinet.

[0030] The shaft of the drive motor 5 passes through the rear side wall of the main body 1 of the power distribution cabinet, and the rear end of the shaft of the drive motor 5 is fixedly connected to the reel 501. The pull rope 502 is wound on the reel 501, and the lower end of the pull rope 502 is fixedly connected to the rear side of the upper end face of the lifting frame 201. Through the cooperative design of the drive motor 5, the reel 501 and the pull rope 502, the lifting frame 201 is moved upward.

[0031] The automatic locking mechanism 6 includes a rectangular sliding shell 601, which is fixedly connected to the rear side of the main body 1 of the distribution cabinet. A rectangular slider 602 is slidably connected inside the rectangular sliding shell 601. A plug-in block 603, penetrating the rectangular sliding shell 601 and the rear side wall of the main body 1 of the distribution cabinet, is fixedly connected to the rear end face of the rectangular slider 602. The lower edge of the rear end of the plug-in block 603 is chamfered. A pull rod 604, penetrating the front side wall of the rectangular sliding shell 601, is fixedly connected to the front end face of the rectangular slider 602. The pull rod 604 is located outside the rectangular sliding shell 601. A spring is provided; when the automatic locking mechanism 6 is in the locking limit state, the rear end of the plug block 603 is plugged into the rectangular socket 209, and at this time, both the side sealing plate 302 and the bottom sealing plate 4 are in a sealed state; through the cooperative design of the automatic locking mechanism 6, the limit rod 208 and the rectangular socket 209, after the bottom sealing plate 4 completes the sealing of the bottom of the distribution cabinet body 1, the limit rod 208 can be reliably locked on the rear side of the distribution cabinet body 1, which significantly enhances the stability of the bottom sealing plate 4 and the side sealing plate 302 in the sealed state.

[0032] Example 2, based on Example 1, such as Figure 7 and Figure 8 As shown, the automatic unlocking mechanism 7 includes a push-pull electromagnet 701, which is installed inside the rear side of the main body 1 of the distribution cabinet and located at the bottom of the automatic locking mechanism 6. A pull rope 702 is fixedly connected to the front end of the push-pull rod on the push-pull electromagnet 701, and the other end of the pull rope 702 is fixedly connected to the front end of the pull rod 604. A pulley 703 is slidably connected to the outside of the pull rope 702. The pulley 703 is installed inside the rear side of the main body 1 of the distribution cabinet via a bracket 704. A U-shaped limiting plate 705 is fixedly connected to the rear end of the bracket 704. An arc-shaped notch is provided on the rear side of the U-shaped limiting plate 705, and the arc-shaped notch is located outside the pulley 703. The pull rope 702 is located within the U-shaped limiting plate 705. Inside the position plate 705, the U-shaped limiting plate 705 effectively guides and limits the pull rope 702, preventing it from detaching from the pulley 703 and improving the reliability of the automatic unlocking mechanism 7. With the automatic unlocking mechanism 7, when the seal needs to be released, simply energizing the push-pull electromagnet 701 quickly pulls the rear end of the plug block 603 out of the rectangular socket 209, and the limiting rod 208 is unlocked. Subsequently, the lifting frame 201 moves the bottom sealing plate 4 down to reset, while the side sealing plates 302 on both sides move up to return to their original positions, quickly releasing the seal. Since there is no need to control the reverse operation of the drive motor 5, the operation process is significantly simplified.

[0033] The working principle of this invention: In rainy weather, the raindrop sensor 104 senses the rain and transmits the rain signal to the controller 103. At this time, the controller 103 controls the drive motor 5 to rotate a certain number of times, causing the reel 501 to rotate a certain number of times, thereby winding the pull rope 502. This causes the lifting frame 201, the lower U-shaped connecting plate 203, and the bottom sealing plate 4 to move upward. At this time, the guide slide cylinder 202 and the external spring of the support slide column 101 are in a compressed state. Then, the lower U-shaped connecting plate 203 causes the lower end of the lever 204 to rotate upward. Under the action of the support frame 2011, the upper end of the lever 204 rotates downward, thereby causing the upper U-shaped connecting plate 205, the drive plate 206, the connecting slide rod 303, and the side sealing plate 302 to move downward synchronously. When the bottom sealing plate... After the frame-shaped sealing gasket 401 on the 4th surface makes tight contact with the bottom surface of the main body 1 of the distribution cabinet, the side sealing plates 302 on the left and right sides of the main body 1 of the distribution cabinet cover the heat dissipation holes on the left and right sides of the main body 1 of the distribution cabinet, so that the corresponding heat dissipation holes are effectively blocked and sealed to prevent rainwater from entering the interior of the main body 1 of the distribution cabinet. Moreover, when sealing, the bottom sealing plate 4 and the side sealing plate 302 can be driven by the lower U-shaped connecting plate 203, the lever 204, the upper U-shaped connecting plate 205 and the support frame 2011, which simplifies the overall structure. Even if fallen leaves or other debris fall on these structures, they are not easy to get stuck, which significantly improves the reliability of waterproof sealing. Moreover, only one drive motor 5 is needed to drive it, which effectively saves manufacturing costs and energy consumption.

[0034] After the bottom sealing plate 4 seals the bottom of the main body 1 of the distribution cabinet, the rectangular slider 602 moves rapidly backward with the plug block 603 under the action of the spring force of the external spring of the pulling rod 604, so that the rear end of the plug block 603 automatically plugs into the rectangular socket 209. At this time, the limiting rod 208 is effectively limited on the rear side of the main body 1 of the distribution cabinet, so that the bottom sealing plate 4 and the side sealing plate 302 are more stable and reliable when performing sealing operations, and avoid the phenomenon of the lifting frame 201 falling back after the motor 5 stops rotating.

[0035] When the seal needs to be released, simply power the push-pull electromagnet 701 to move the push-pull rod on the electromagnet 701 backward along with the lower end of the pull rope 702. This pulls the pull rod 604, the rectangular slider 602, and the plug block 603 forward, causing the rear end of the plug block 603 to be pulled out from inside the rectangular socket 209. This removes the limit rod 208 from its limit position. Then, under the action of the spring force of the guide slide cylinder 202 and the support slide column 101, the lifting frame 201 moves back to its original position. At the same time, the side sealing plates 302 on both sides also move back to their original positions. This allows for quick release of the seal. During the release of the seal, there is no need to control the reverse operation of the drive motor 5, making the operation process simpler and the response efficiency higher.
