Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a low-voltage power distribution cabinet with dehumidification function. Background Technology

[0002] Low-voltage distribution cabinets, commonly known as low-voltage switch cabinets, are a crucial piece of equipment in power systems. Low-voltage distribution cabinets refer to complete sets of electrical devices with AC and DC voltages below 1000V. They are characterized by their small size, light weight, compact structure, and ease of installation and use. The manufacturers are responsible for completing all internal electrical and mechanical connections and assembling the devices together with structural components to form a complete assembly.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] However, existing low-voltage distribution cabinets may accumulate significant moisture during rainy weather. This moisture can adhere to electronic components, potentially causing short circuits and damage. While dehumidification devices are installed inside the distribution cabinet, these devices are often fixed in specific locations. However, the gaps between electronic components installed at higher locations are not easily dehumidified, reducing dehumidification efficiency. This can lead to incomplete removal of moisture from the electronic components, resulting in short circuits or damage.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a low-voltage distribution cabinet with dehumidification function, which solves the problem that the dehumidification equipment is fixedly installed in the braking position inside the main body of the distribution cabinet, resulting in incomplete dehumidification inside the main body of the distribution cabinet and moisture still sticking to the gaps between electronic components, causing short circuits or damage to the electronic components.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A low-voltage distribution cabinet with dehumidification function includes a cabinet body. First cavities are formed on both sides of the bottom of the cabinet body. A first servo motor is fixedly installed at the front end of each first cavity. A first lead screw is fixedly installed at the output end of the first servo motor. First fixing rods are fixedly installed on both sides of the top of the cabinet body. A first collar is sleeved on the outer side of the first lead screw and the first fixing rod, and the first collar and the first lead screw are connected by threads. A connector is fixedly installed at one end of the first collar that is close to the other. A second servo motor is fixedly installed at the bottom of the connector. A second lead screw, rotatably connected to the bottom connector, is fixedly installed at the output end of the second servo motor. A dehumidification device is threadedly installed on the outer side of the second lead screw.

[0009] Preferably, the dehumidifier has arc grooves at its front and rear ends on opposite sides, and a rotating ball is rotatably installed inside the arc grooves.

[0010] Preferably, the bottom of the main body of the power distribution cabinet is provided with sliding grooves on both sides, and a slider that is fixedly connected to the bottom connector is slidably installed inside the sliding groove.

[0011] Preferably, a mounting frame is movably installed inside the main body of the power distribution cabinet, and second fixing rods are fixedly installed on both sides of the top of the main body of the power distribution cabinet. A second ring is sleeved on the outer side of the second fixing rod and fixedly connected to the top of the mounting frame. Handles are fixedly installed on both sides of the front end of the mounting frame, and wheels are fixedly installed on both sides of the bottom of the mounting frame.

[0012] Preferably, a partition is fixedly installed inside the mounting bracket. The front end of the partition is evenly provided with wire harness grooves. A second cavity is provided between the wire harness grooves. A rotating rod is rotatably installed inside the second cavity. A limiting rod extending to the front end of the wire harness groove is fixedly installed on the outside of the rotating rod. A torsion spring fixedly connected to the limiting rod is sleeved on the outside of the rotating rod. The ends of the torsion springs that are far apart from each other are fixedly connected to the inner wall of the second cavity.

[0013] Preferably, a sealing door is rotatably installed at the front end of the main body of the power distribution cabinet, and a heat dissipation hole is provided at the bottom of the sealing door, with a dustproof mesh installed inside the heat dissipation hole.

[0014] Compared with the prior art, this utility model provides a low-voltage distribution cabinet with dehumidification function, which has the following beneficial effects: This utility model uses a first servo motor to drive the first lead screw to rotate, so that the first fixed rod moves laterally on the outside of the first lead screw and the first fixed rod, thereby driving the dehumidification device to move laterally. A second servo motor drives the second lead screw to rotate, so that the dehumidification device moves vertically on the outside of the second lead screw. This allows the dehumidification device to move omnidirectionally on both sides inside the distribution cabinet body to perform dehumidification operations. This ensures that the gaps between the electronic components inside the distribution cabinet body are thoroughly dehumidified, avoiding the situation where the dehumidification device is fixed in a braking position inside the distribution cabinet body, resulting in incomplete dehumidification inside the distribution cabinet body and moisture still sticking to the gaps between the electronic components, which could lead to short circuits or damage to the electronic components.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a low-voltage distribution cabinet with dehumidification function.

[0024] Please see Figures 1-6 A low-voltage distribution cabinet with dehumidification function includes a cabinet body 1. First cavities 101 are formed on both sides of the bottom of the cabinet body 1. A first servo motor 102 is fixedly installed at the front end inside the first cavity 101. A first lead screw 103 is fixedly installed at the output end of the first servo motor 102. First fixing rods 104 are fixedly installed on both sides of the top inside the cabinet body 1. A first collar 105 is sleeved on the outer side of the first lead screw 103 and the first fixing rod 104, and the first collar 105 is threadedly connected to the first lead screw 103. A connector 106 is fixedly installed at one end of the first collar 105 that is close to each other. A second servo motor 107 is fixedly installed at the bottom of the top connector 106. A second lead screw 108, rotatably connected to the bottom connector 106, is fixedly installed at the output end of the second servo motor 107. A dehumidification device 109 is threadedly sleeved on the outer side of the second lead screw 108.

[0025] With the above-described structural configuration, the low-voltage distribution cabinet with dehumidification function drives the first lead screw 103 to rotate via the output end of the first servo motor 102, allowing the first collar 105 to reciprocate laterally on the outside of the first fixed rod 104 and the first lead screw 103 respectively. This causes the dehumidification device 109 to reciprocate laterally inside the main body 1 of the distribution cabinet. The output end of the second servo motor 107 drives the second lead screw 108 to rotate, causing the dehumidification device 109 to reciprocate longitudinally inside the main body 1 of the distribution cabinet. At this time, the dehumidification device 109 performs all-round dehumidification inside the main body 1 of the distribution cabinet, thus thoroughly dehumidifying the gaps between electronic components inside the main body 1 of the distribution cabinet. This avoids the problem of incomplete dehumidification inside the main body 1 of the distribution cabinet due to the dehumidification device 109 being fixedly installed in a braking position inside the main body 1 of the distribution cabinet, resulting in moisture sticking to the gaps between electronic components and causing short circuits or damage to the electronic components.

[0026] Furthermore, the dehumidifier 109 has arc grooves 110 at its front and rear ends on opposite sides, and a rotating ball 111 is rotatably installed inside the arc grooves 110. When the dehumidifier 109 performs omnidirectional reciprocating motion inside the main body of the distribution cabinet 1, the rotating ball 111 rotates inside the arc grooves 110 and is in contact with the inner wall of the main body of the distribution cabinet 1, making the movement of the dehumidifier 109 more stable. At the same time, it also limits the movement of the dehumidifier 109 and prevents it from shaking as the second lead screw 108 rotates.

[0027] Furthermore, the bottom of the main body of the power distribution cabinet 1 is provided with sliding grooves 112 on both sides, and a slider 113 fixedly connected to the bottom connector 106 is slidably installed inside the sliding grooves 112. When the connector 106 moves laterally inside the main body of the power distribution cabinet 1, the slider 113 slides inside the sliding grooves 112, making the lateral movement of the dehumidification device 109 more stable.

[0028] Furthermore, a mounting frame 2 is movably installed inside the main body 1 of the distribution cabinet. Second fixing rods 202 are fixedly installed on both sides of the top of the main body 1. A second collar 203, which is fixedly connected to the top of the mounting frame 2, is sleeved on the outer side of the second fixing rods 202. Handles 209 are fixedly installed on both sides of the front end of the mounting frame 2, and wheels 210 are fixedly installed on both sides of the bottom of the mounting frame 2. When an operator holds the handles 209 and pulls the mounting frame 2 outwards, the second collar 203 moves outwards from the second fixing rods 202, and the wheels 210 slide at the bottom of the main body 1, thereby pulling out the mounting frame 2. This facilitates the installation of electrical and electronic components onto the mounting frame 2.

[0029] Furthermore, a partition 201 is fixedly installed inside the mounting frame 2. The front end of the partition 201 is evenly provided with wire harness grooves 204. A second cavity 205 is provided between the wire harness grooves 204. A rotating rod 206 is rotatably installed inside the second cavity 205. A limiting rod 207 extending to the front end of the wire harness groove 204 is fixedly installed on the outside of the rotating rod 206. A torsion spring 208 fixedly connected to the limiting rod 207 is sleeved on the outside of the rotating rod 206. The ends of the torsion springs 208 that are far apart from each other are fixedly connected to the inner wall of the second cavity 205. When the electronic components are installed on the mounting bracket 2, the cable tray 204 is opened by rotating the limiting rod 207. Then, the connecting wires of the electronic components are placed inside the cable tray 204 and bound. Under the torque of the torsion spring 208, the limiting rod 207 is reset to close the opening at the front end of the cable tray 204. This allows the connecting wires of the electronic components to be bound in categories inside the cable tray 204, preventing the connecting wires of the electronic components from getting tangled and knotted, which could damage the electronic components.

[0030] Furthermore, a sealing door 3 is rotatably installed at the front end of the main body 1 of the distribution cabinet. A heat dissipation hole 301 is provided at the bottom of the sealing door 3, and a dustproof mesh is installed inside the heat dissipation hole 301. When the sealing door 3 is closed, heat dissipation is achieved through the heat dissipation hole 301, while the dustproof mesh provides dust protection, preventing external dust from entering the main body of the distribution cabinet and affecting the heat dissipation of electronic components.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
