Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a waterproof structure for power distribution cabinets. Background Technology

[0002] Distribution cabinets can be broadly classified into three categories: power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment in a power distribution system and are also a general term for motor control centers. Distribution cabinets are suitable for situations where the load is relatively dispersed and there are fewer circuits. Among them, outdoor distribution cabinets, unlike indoor distribution cabinets, are not placed in sheltered locations, which allows rainwater to enter the cabinet. Therefore, a waterproof structure is required.

[0003] The utility model patent with publication number CN220585763U discloses a waterproof structure for a power distribution cabinet. This utility model has a series of structures that enable rapid drainage, preventing the drainage outlets from being easily blocked by leaves or other debris falling onto the cabinet shell, thus avoiding drainage difficulties. The drainage is convenient and quick, and the cabinet shell also has ventilation and moisture-proof functions, sealing and blocking water that leaks into the cabinet shell to ensure dryness inside the cabinet shell.

[0004] However, most of the existing waterproof structures used in distribution cabinets are fixed, making it difficult to adjust the tilt angle of the rainproof structure to quickly drain rainwater. This allows rainwater or snowmelt to enter, affecting the normal use of the distribution cabinet. In addition, the functionality of the waterproof structure is relatively limited. In harsh environments (such as snow or freezing), the waterproof structure is prone to snow accumulation, which can cause damage over time and hinder the extension of its service life. Utility Model Content

[0005] This utility model provides a waterproof structure for power distribution cabinets, which has the advantages of easy angle adjustment and multi-functionality, so as to solve the problems of existing structures that are inconvenient to adjust the tilt angle of rainproof structures and are inconvenient to extend the service life of waterproof structures.

[0006] To achieve the goals of changing angles and multifunctionality, this utility model provides the following technical solution: a waterproof structure for a power distribution cabinet, comprising two support rods and a drive motor, wherein the two support rods are installed on both sides of the top surface of the power distribution cabinet, and the drive motor is installed on the inner top wall of the power distribution cabinet, and further comprising:

[0007] A limiting frame is set at the top of the support rod, and waterproof plates are rotatably connected to both sides of the limiting frame. A heating component is fixedly installed inside each of the two waterproof plates. The heating component includes a heat insulation plate and a heating wire.

[0008] A monitoring component is installed at the top of the limiting frame, the monitoring component including an integrated rain and snow sensor and a PLC controller;

[0009] A support assembly disposed on the surfaces of two support rods, the support assembly comprising a sliding sleeve, a connecting column, a support column, and a connecting ring;

[0010] A support plate is set inside the two sliding components. The output end of the drive motor is fixedly connected to an adjustment component, which includes a lead screw and a lifting sleeve.

[0011] As a preferred technical solution of this utility model, the monitoring component includes an integrated rain and snow sensor fixedly connected to the top of the limiting frame. The output end of the integrated rain and snow sensor is electrically connected to a PLC controller via a composite cable. The PLC controller is installed inside the power distribution cabinet.

[0012] As a preferred embodiment of this utility model, the heating assembly includes heat insulation plates that are fixedly connected inside two waterproof plates. A heating wire is provided on the top surface of the heat insulation plate. The output end of the heating wire is electrically connected to the power supply equipment in the power distribution cabinet. The heating wire is electrically connected to the PLC controller through a signal line.

[0013] As a preferred embodiment of the present invention, the support assembly includes a sliding sleeve that is slidably fitted onto the surface of the support rod. Both sides of the sliding sleeve are rotatably connected to support columns via connecting columns, and one end of each support column is fixedly connected to a connecting ring.

[0014] As a preferred embodiment of this utility model, the connecting ring is rotatably connected to an assembly column, and the surface of the assembly column is rotatably connected to a fixing ring, which is installed on both sides of the bottom surface of the waterproof membrane.

[0015] As a preferred embodiment of this utility model, a plurality of connecting springs are fixedly connected to the top of the supporting plate, and the top of the connecting springs is fixedly connected to the bottom surface of the limiting frame.

[0016] As a preferred embodiment of this utility model, the adjustment component includes a lead screw fixedly connected to the output end of the drive motor, a lifting sleeve being threaded onto the surface of the lead screw, and the top end of the lifting sleeve being fixedly connected to the middle of the bottom surface of the support plate.

[0017] As a preferred embodiment of this utility model, the surface of the waterproof membrane is provided with a drainage groove, which is used for rapid drainage.

[0018] Compared with the prior art, this utility model provides a waterproof structure for power distribution cabinets, which has the following beneficial effects:

[0019] 1. This waterproof structure for the power distribution cabinet, through the installation of a waterproof plate, a drainage channel, a support assembly, and an adjustment assembly, can quickly clear accumulated water by changing the tilt angle of the waterproof plate. During use, an integrated rain and snow sensor monitors external weather changes. When rain is detected, the integrated rain and snow sensor sends a signal to the PLC controller, which then sends an operation command to the drive motor. The lead screw rotates, moving the lifting sleeve and lowering the support plate. The waterproof plate tilts, allowing rainwater to quickly slide down from the drainage channel, thereby reducing rainwater accumulation. This prevents the waterproof structure of the power distribution cabinet from being fixed and allowing rainwater to accumulate for a long time, affecting the normal use of the power distribution cabinet and helping to ensure the operating efficiency of the power distribution cabinet.

[0020] 2. This waterproof structure for the distribution cabinet achieves multi-functionality by incorporating monitoring and heating components. When snow is detected, the integrated rain and snow sensor sends a signal to the PLC controller, which then sends an operation command to the drive motor and activates the heating wire to heat the waterproof plate. This melts the snow and allows the melted water to slide down the waterproof plate, thus quickly clearing the snow and preventing it from accumulating on the top surface of the distribution cabinet, which could damage the waterproof structure over time. This helps extend the service life of the waterproof structure. Attached Figure Description

[0027] Please see Figures 1-4 This utility model discloses a waterproof structure for a power distribution cabinet, including two support rods 1 and a drive motor 2. The two support rods 1 are installed on both sides of the top surface of the power distribution cabinet, and the drive motor 2 is installed on the inner top wall of the power distribution cabinet. It also includes:

[0028] A limiting frame 3 is set at the top of the support rod 1. Waterproof plates 4 are rotatably connected to both sides of the limiting frame 3. Heating components 10 are fixedly installed inside the two waterproof plates 4. The heating components 10 include heat insulation plates 1001 and heating wires 1002.

[0029] The monitoring component 6 is set at the top of the limit frame 3. The monitoring component 6 includes an integrated rain and snow sensor 601 and a PLC controller 602.

[0030] The support assembly 7 is provided on the surfaces of the two support rods 1. The support assembly 7 includes a sliding sleeve 701, a connecting column 702, a support column 703, and a connecting ring 704.

[0031] The support plate 8 is set inside the two sliding components 701. The output end of the drive motor 2 is fixedly connected to the adjustment component 9, which includes a lead screw 901 and a lifting sleeve 902.

[0032] Specifically, the monitoring component 6 includes an integrated rain and snow sensor 601 fixedly connected to the top of the limiting frame 3. The output end of the integrated rain and snow sensor 601 is electrically connected to a PLC controller 602 via a composite cable. The PLC controller 602 is installed inside the power distribution cabinet.

[0033] In this embodiment, during use, the integrated rain and snow sensor 601 monitors external weather changes. When rain or snow is detected, the integrated rain and snow sensor 601 sends a signal to the PLC controller 602, and the PLC controller 602 issues corresponding instructions.

[0034] Specifically, the heating assembly 10 includes a heat insulation plate 1001 that is fixedly connected inside two waterproof plates 4. A heating wire 1002 is provided on the top surface of the heat insulation plate 1001. The output end of the heating wire 1002 is electrically connected to the power supply equipment in the power distribution cabinet. The heating wire 1002 is electrically connected to the PLC controller 602 through a signal line.

[0035] In this embodiment, the PLC controller 602 and the heating wire 1002 are connected to the power supply equipment inside the power distribution cabinet. The PLC controller 602 issues a power supply command, causing the power supply equipment to supply power to the heating wire 1002. The heating wire 1002 heats up and generates heat, melting the snow on the waterproof plate 4.

[0036] Specifically, the support assembly 7 includes a sliding sleeve 701 that is slidably sleeved on the surface of the support rod 1. Both sides of the sliding sleeve 701 are rotatably connected to the support column 703 via the connecting column 702. One end of the support column 703 is fixedly connected to the connecting ring 704.

[0037] In this embodiment, the sliding kit 701 slides up and down on the support rod 1, and adjusts the angle of the support column 703.

[0038] Specifically, the connecting ring 704 is rotatably connected to the assembly column 11, and the surface of the assembly column 11 is rotatably connected to the fixing ring 12, which is installed on both sides of the bottom surface of the waterproof plate 4.

[0039] In this embodiment, the fixing ring 12 is connected to the waterproof membrane 4, and the support column 703 changes the support angle, so that the waterproof membrane 4 changes the tilt angle.

[0040] Specifically, several connecting springs 13 are fixedly connected to the top of the supporting plate 8, and the top of the connecting springs 13 is fixedly connected to the bottom surface of the limiting frame 3.

[0041] In this embodiment, the connecting spring 13 is elastic, which facilitates the connection between the limiting frame 3 and the supporting plate 8.

[0042] Specifically, the adjustment component 9 includes a lead screw 901 fixedly connected to the output end of the drive motor 2, and a lifting sleeve 902 is threadedly connected to the surface of the lead screw 901. The top end of the lifting sleeve 902 is fixedly connected to the middle of the bottom surface of the support plate 8.

[0043] In this embodiment, the drive motor 2 is started, the lead screw 901 rotates, and the lifting sleeve 902 moves.

[0044] Specifically, the surface of the waterproof membrane 4 is provided with a drainage groove 5, which is used for rapid drainage.

[0045] In this embodiment, the waterproof membrane 4 changes its tilt angle, allowing rainwater or snowmelt to slide out quickly from the guide channel 5.

[0046] The working principle and usage process of this utility model are as follows: The support rod 1 is installed on the top surface of the distribution cabinet, and the drive motor 2 is installed on the inner top wall of the distribution cabinet. An integrated rain and snow sensor 601 monitors external weather changes. When rain or snow is detected, the integrated rain and snow sensor 601 sends a signal to the PLC controller 602. The PLC controller 602 then issues a corresponding command to start the drive motor 2. The lead screw 901 rotates, moving the lifting sleeve 902. The sliding assembly 701 slides up and down on the support rod 1, carrying... The support column 703 is angled, and the fixing ring 12 is connected to the waterproof plate 4. The support column 703 changes the support angle, so that the waterproof plate 4 changes the tilt angle. The PLC controller 602 and the heating wire 1002 are connected to the power supply equipment inside the power distribution cabinet. The PLC controller 602 issues a power supply command, so that the power supply equipment supplies power to the heating wire 1002. The heating wire 1002 heats up and generates heat, which melts the snow on the waterproof plate 4. The waterproof plate 4 changes the tilt angle, so that rainwater or snow water can quickly slide out from the guide channel 5.

[0047] In summary, this waterproof structure for the power distribution cabinet, by setting up a waterproof plate 4, a guide channel 5, a support component 7, and an adjustment component 9, can achieve the effect of quickly clearing accumulated water by changing the tilt angle of the waterproof plate 4. During use, the integrated rain and snow sensor 601 monitors external weather changes. When rain is detected, the integrated rain and snow sensor 601 sends a signal to the PLC controller 602, and then the PLC controller 602 sends an operation command to the drive motor 2. The lead screw 901 rotates, moving the lifting sleeve 902, causing the support plate 8 to descend. The waterproof plate 4 tilts at an angle, and rainwater slides quickly down from the guide channel 5, thereby reducing rainwater accumulation. This avoids the waterproof structure of the power distribution cabinet being fixed and rainwater accumulating for a long time, which would affect the normal use of the power distribution cabinet and help ensure the operating efficiency of the power distribution cabinet.

[0048] By setting up the monitoring component 6 and the heating component 10, the waterproof structure can achieve multi-functionality. When snow is detected, the integrated rain and snow sensor 601 will send a signal to the PLC controller 602. Then, the PLC controller 602 will send an operation command to the drive motor 2 and start the heating wire 1002 to heat the waterproof plate 4. The snow melts and the snow water slides down the waterproof plate 4, thereby quickly clearing the snow and preventing snow from covering the top surface of the distribution cabinet, which would damage the waterproof structure over time. This helps to extend the service life of the waterproof structure.
