Description

Technical Field

[0001] The utility model relates to the field of low-voltage power distribution cabinets, in particular to a low-voltage cabinet capable of preventing internal electrical components from being affected by moisture. Background Art

[0002] A low-voltage distribution cabinet is a device used to distribute electrical energy, typically installed at the end of a power system, distributing it to individual devices or to the next-level distribution system. Its safety, reliability, and ease of maintenance make it widely used in various settings, including factories, residences, commercial centers, transportation, agriculture, and healthcare. Factories, with their large number of electric motors and other electrical equipment, require low-voltage distribution cabinets to provide a reliable power supply; residential communities rely on them for the rational distribution and management of power; and commercial centers rely on them to meet the power needs of various commercial facilities.

[0003] Distribution cabinets are often installed in harsh environments, such as high-temperature, high-humidity production workshops and food processing plants. Due to poor sealing conditions, large amounts of moisture can flow into the cabinets. Due to poor ventilation within the cabinets, this moisture cannot be expelled promptly. Condensation forms on cool components and cabinet walls. Prolonged operation of electrical equipment within the distribution cabinet in a humid environment can easily cause short circuits, disrupting normal production.

[0004] To sum up, there are many disadvantages, which are summarized as follows:

[0005] ① The operating environment of some low-voltage cabinets is very harsh. When moisture enters the low-voltage cabinet, it cannot be discharged in time. When there is a large temperature difference between the internal temperature of the low-voltage cabinet and the external environment, condensation will form on the cabinet wall.

[0006] ② The electrical components in the low-voltage cabinet cannot operate in a humid environment for a long time, which will cause the electrical components inside the low-voltage cabinet to be damp and short-circuited; Utility Model Content

[0007] In view of the deficiencies in the prior art, the present invention provides a method to solve the above problems.

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions.

[0009] A low-voltage cabinet for preventing internal electrical components from getting damp, comprising a low-voltage cabinet, a ball screw assembly A, a ball screw assembly B, a humidity sensor, a water leakage groove, a water leakage hole A, a water leakage hole B, a water leakage hole C, and a scraper. The ball screw assembly A, the ball screw assembly B, the humidity sensor, the water leakage groove, and the scraper are arranged inside the low-voltage cabinet. The scraper is provided with three protrusions, which are respectively arranged in the middle and at both ends of the scraper. The scraper as a whole has a curvature and contacts the cabinet surface of the low-voltage cabinet.

[0010] Preferably, the arc length of the scraper is in the range of 90-95 cm, which is more conducive to quickly scraping off the condensation.

[0011] Preferably, the ball screw assembly A, ball screw assembly B, humidity sensor, and water leakage groove are arranged on the cabinet surface inside the low-voltage cabinet, and the water leakage hole A, water leakage hole B, and water leakage hole C are arranged in the water leakage groove.

[0012] Preferably, the ball screw assembly A is connected to the scraper via bolts, and the ball screw assembly B is connected to the scraper via bolts.

[0013] Preferably, the ball screw assembly A is interconnected with the humidity sensor, and the ball screw assembly B is interconnected with the humidity sensor.

[0014] Preferably, leakage hole A, leakage hole B and leakage hole C are provided at the bottom of the leakage trough.

[0015] Preferably, the drainage trough is curved as a whole, and is used in conjunction with a scraper.

[0016] Preferably, the water leakage hole A is arranged in the middle of the water leakage trough, and the water leakage hole B and the water leakage hole C are arranged at both ends of the water leakage trough.

[0017] Preferably, the ball screw assembly A and the ball screw assembly B are symmetrically arranged.

[0018] Preferably, the ball screw assembly A and the ball screw assembly B work synchronously, ensuring the stability of the scraper during operation.

[0019] Compared with the existing technology, the utility model discloses a low-voltage cabinet that prevents internal electrical components from getting damp, including a low-voltage cabinet, a ball screw assembly A, a ball screw assembly B, a humidity sensor, a leakage trough, a leakage hole A, a leakage hole B, a leakage hole C, and a scraper, which are used in combination with each other to play a role.

[0020] ① The scraper of this low-voltage cabinet is curved as a whole, and the convex part of the scraper is designed with a smooth transition from wide to narrow. As the condensation flows downward, it will slowly gather on the convex part and drip into the drain tank when it reaches a certain weight.

[0021] ③The humidity sensor senses the humidity inside the low-voltage cabinet. Ball screw assembly A and ball screw assembly B drive the scraper to scrape the condensation inside the low-voltage cabinet into the leakage trough, and then discharge it to the outside of the cabinet through leakage holes A, B, and C, to prevent the electrical components inside the low-voltage cabinet from running in a humid environment for a long time due to moisture and short circuit.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] A low-voltage cabinet that prevents internal electrical components from getting damp, comprising a low-voltage cabinet 1, a ball screw assembly A2, a ball screw assembly B21, a humidity sensor 3, a water leakage groove 4, a water leakage hole A5, a water leakage hole B51, a water leakage hole C52, and a scraper 6. The ball screw assembly A2, the ball screw assembly B21, the humidity sensor 3, the water leakage groove 4, and the scraper 6 are arranged inside the low-voltage cabinet 1. The scraper 6 is provided with three protrusions, which are respectively arranged in the middle and at both ends of the scraper. The scraper 6 is curved as a whole, and the scraper 6 contacts the cabinet surface of the low-voltage cabinet 1.

[0028] like Figure 2 、 Figure 4 As shown, the protrusion of the scraper 6 is designed with a smooth transition from wide to narrow, so when the scraper 6 moves from top to bottom, condensation will drip along the protrusion into the drainage trough 4.

[0029] The arc length of the scraper 6 is in the range of 90-95 cm, which is more conducive to quickly scraping off the condensation.

[0030] The ball screw assembly A2, the ball screw assembly B21, the humidity sensor 3, and the water leakage groove 4 are arranged on the cabinet surface inside the low-voltage cabinet 1, and the water leakage hole A5, the water leakage hole B51, and the water leakage hole C52 are arranged in the water leakage groove 4.

[0031] The ball screw assembly A2 is connected to the scraper 6 by bolts, and the ball screw assembly B21 is connected to the scraper 6 by bolts.

[0032] The ball screw assembly A2 is connected to the humidity sensor 3, and the ball screw assembly B21 is connected to the humidity sensor 3.

[0033] The bottom of the leakage groove 4 is provided with leakage holes A5, B51 and C52.

[0034] The drainage groove 4 is curved as a whole, and is used in conjunction with the scraper 6 .

[0035] The leakage hole A5 is arranged in the middle of the leakage groove 4, and the leakage holes B51 and C52 are arranged at both ends of the leakage groove 4.

[0036] like Figure 3 As shown, the drainage groove 4 is curved as a whole, and the condensation generated on the cabinet surface is scraped into the drainage groove 4 by the scraper 6 and can slide into the drainage holes B51 and C52 along the curvature.

[0037] The ball screw assembly A2 and the ball screw assembly B21 are symmetrically arranged.

[0038] The ball screw assembly A2 and the ball screw assembly B21 work synchronously, and the stability of the scraper 6 during operation needs to be ensured.

[0039] The usage scenario is that the ball screw assembly A2, ball screw assembly B21, and humidity sensor 3 are connected to the power supply in the cabinet, the scraper 6 is installed with the ball screw assembly A2 and ball screw assembly B21, and a humidity value is set for the humidity sensor 3. When the humidity in the low-voltage cabinet 2 reaches the set value, the ball screw assembly A2 and ball screw assembly B21 start working, and the scraper 6 moves downward from the upper end of the cabinet surface. During the process, condensation is gathered on the protrusion. When the condensation reaches a certain weight, it will drip down into the leakage groove 4. The condensation can be discharged from the cabinet through the leakage holes A5, leakage holes B51, and leakage holes C52, reducing the humidity inside the low-voltage cabinet and preventing the electrical components inside the low-voltage cabinet 1 from being damp and short-circuited due to long-term operation in a humid environment.

[0040] The ball screw assembly A2 and the ball screw assembly B21 mentioned above are conventional designs in the prior art and are not the core invention of this solution, so they will not be elaborated in this solution.
