Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to power distribution cabinets. Background Technology
[0002] In the power distribution system of a construction site, the distribution cabinet is the core equipment of the power system. The distribution cabinet is responsible for the distribution, control and protection of electrical energy. When the distribution cabinet is installed on the construction site, in order to reduce the temporary power transmission distance and reduce voltage loss and safety hazards caused by excessively long lines, the distribution cabinet is usually installed at the construction passage or construction entrance. During the rainy season, in order to prevent the electrical components inside the distribution cabinet from being corroded by rainwater, a rain shield is usually installed on the top of the distribution cabinet. The rain shield protects the distribution cabinet from the rainy environment, thereby preventing rainwater from entering the distribution cabinet and causing short circuits, corrosion or insulation failure.
[0003] Currently, the rain cover on the top of the distribution cabinet is usually fixed in the existing technology. However, due to the limited installation space of the distribution cabinet at the construction site, the fixed rain cover occupies a lot of space and can easily affect the construction operation in the daily use of the distribution cabinet, so it has low practicality. Utility Model Content
[0004] Therefore, it is necessary to provide a distribution cabinet to address the problems of fixed rain shields occupying a lot of space and easily affecting construction operations in daily use of the distribution cabinet, resulting in low practicality.
[0005] The device includes: a distribution cabinet body; and a rain shelter mechanism, wherein the rain shelter mechanism includes a rain shelter plate and a sliding frame slidably connected to the upper end of the inner wall of the distribution cabinet body shell. A slider is slidably connected to the inner wall of the sliding frame. The top end of the slider is fixedly connected to the bottom end of the rain shelter plate. A spring is fixedly connected between one side of the slider and the inner wall of the sliding frame. A sliding rod is fixedly connected to one side of the sliding frame. A threaded rod is threadedly connected to one side of the inner wall of the sliding rod. The bottom end of the threaded rod passes through the outer shell of the distribution cabinet body and is fixedly connected to a round block.
[0006] In one embodiment, the top of the rain shelter has a cavity, the inner bottom wall of the cavity forms an angle with the horizontal plane, and a drainage groove is provided on the side of the rain shelter away from the sliding frame, and the drainage groove is connected to the cavity. This facilitates the guidance of rainwater entering the cavity away from the main body of the distribution cabinet, improving the protective effect of the rain shelter when it is rainproof.
[0007] In one embodiment, a limiting groove is formed on the surface of the distribution cabinet body shell, with the opening of the limiting groove facing downwards, and the smooth rod of the threaded rod located within the limiting groove. This facilitates limiting the movement path of the threaded rod.
[0008] In one embodiment, a protective plate is fixedly connected to one side of the rain shield. The protective plate is generally shaped like a flat-topped cone, and its inner wall has a through groove. There are comments regarding the protection of the opening where the rain shield is installed on the outer casing of the distribution cabinet.
[0009] In one embodiment, the channel is inclined, and its higher end communicates with the drainage channel. The inclined channel ensures drainage while preventing external impurities from entering the channel and drainage channel during the storage of the rain shield.
[0010] In one embodiment, a first magnetic plate is embedded in the front end of the distribution cabinet body shell, and a second magnetic plate is embedded in the side of the protective plate near the distribution cabinet body shell. When the rain shield is stored inside the distribution cabinet body shell, the first and second magnetic plates help to limit the position of the protective plate and the rain shield, ensuring their stability.
[0011] In one embodiment, a circular pad, which is a rubber component, is fixedly connected to the top of the circular block. The circular pad has multiple annularly distributed grooves. This increases the friction between the circular block and the surface of the distribution cabinet's outer casing, ensuring stability when the block is positioned using a threaded rod.
[0012] In one embodiment, the top of the protective panel is at a higher horizontal level than the top of the rain shelter, while the bottom of the protective panel is at a lower horizontal level than the bottom of the rain shelter. This ensures the protective effect of the protective panel.
[0013] Beneficial effects 1. In this solution, a sliding rain shield is installed. When rain shielding is needed, the rain shield can be slid out of the outer shell of the distribution cabinet through the interaction of threaded rod, sliding rod, sliding frame, slider and spring. When the rain shield is hit during the rain shielding process, the rain shield can extend and retract a certain distance under the action of spring, which is beneficial to the protection of the rain shield during the rain shielding process. When the rain shield is not used, the rain shield can be slid into the outer shell of the distribution cabinet for storage, so that the rain shield and the outer shell of the distribution cabinet are integrated. This helps to reduce the space occupied by the distribution cabinet and the rain shield in daily use and avoids affecting the construction operation. The sliding rain shield is more practical in the use of the distribution cabinet. 2. By setting the inner bottom wall of the cavity to be inclined, it is beneficial to guide the rainwater entering the cavity to flow out in a direction away from the main body of the distribution cabinet, thereby improving the protective effect of the rain shield when it is rainproof.

[0022] The following is combined Figures 1-5 This invention describes the power distribution cabinet.
[0023] In one embodiment, the distribution cabinet includes: a distribution cabinet body 100; and a rain shelter mechanism 200. The rain shelter mechanism 200 includes a rain shelter plate 210 and a sliding frame 220 slidably connected to the upper end of the inner wall of the outer shell of the distribution cabinet body 100. A slider 221 is slidably connected to the inner wall of the sliding frame 220. The top end of the slider 221 is fixedly connected to the bottom end of the rain shelter plate 210. A spring 222 is fixedly connected between one side of the slider 221 and the inner wall of the sliding frame 220. A sliding rod 230 is fixedly connected to one side of the sliding frame 220. A threaded rod 240 is threadedly connected to one side of the inner wall of the sliding rod 230. The bottom end of the threaded rod 240 passes through the outer shell of the distribution cabinet body 100 and is fixedly connected to a round block 250.
[0024] In this embodiment, the main components of the distribution cabinet body 100 include: a shell: which protects internal components, prevents electric shock, and prevents external substances from entering; a circuit breaker: used to automatically disconnect the circuit when overload, short circuit, or other faults occur, protecting equipment and personnel safety; a contactor: used for remote control of circuit switching, commonly used for controlling high-power equipment such as motors; a relay: used to realize the logic control, signal amplification, and protection functions of the circuit; a busbar: used to connect various components and distribute electrical energy; and meters and indicator lights: used to display parameters such as voltage, current, and power, and to indicate the working status of the circuit. External electrical equipment is connected to the electrical components inside the distribution cabinet body 100 via wires, and the connection point between the wires and the distribution cabinet body 100 is located at the bottom of the distribution cabinet. A sealing ring is installed at the connection point to seal the connection. The sealing ring is a common sealing method in the prior art. This solution mainly addresses the problem of the rainproof mechanism 200, therefore, the electrical components inside the distribution cabinet body 100 are not described in detail.
[0025] The rain shelter mechanism 200 is installed on the upper inner wall of the outer shell of the power distribution cabinet body 100. The inner wall of the outer shell of the power distribution cabinet body 100 is provided with a sliding groove that matches the rain shelter 210, the sliding frame 220 and the sliding rod 230. A round rod is fixedly connected to the inner wall of the sliding groove. The inner wall of the sliding rod 230 is slidably connected to the surface of the round rod. The round rod limits the movement of the sliding rod 230 and the sliding frame 220.
[0026] like Figure 4 As shown, a cavity 211 is provided at the top of the rain shield 210. The inner bottom wall of the cavity 211 forms an angle with the horizontal plane. A drainage groove is provided on the side of the rain shield 210 away from the sliding frame 220, and the drainage groove is connected to the cavity 211.
[0027] In this embodiment, when the rain shield 210 is slid out from the outer shell of the power distribution cabinet body 100, the lower end of the cavity 211 is far away from the outer shell of the power distribution cabinet body 100, and the drainage groove is located on one side of the lower end of the cavity 211. Therefore, when the rain shield 210 is slid out to provide rain protection, the rainwater falling above the rain shield 210 will enter the cavity 211, and under the action of the inclined surface of the bottom wall of the cavity 211, the rainwater in the cavity 211 will flow away from the power distribution cabinet body 100 and be discharged through the drainage groove.
[0028] like Figure 2 As shown, a limiting groove 110 is provided on the surface of the outer shell of the power distribution cabinet body 100. The opening of the limiting groove 110 faces downward, and the smooth rod of the threaded rod 240 is located in the limiting groove 110.
[0029] In this embodiment, the surface of the threaded rod 240 is slidably connected to the inner wall of the limiting groove 110, and the round block 250 is located below the limiting groove 110. In the initial state, the rain shield 210 is retracted into the outer shell of the power distribution cabinet body 100, and the round block 250 is pressed against the surface of the outer shell of the power distribution cabinet body 100, thereby limiting the sliding rod 230 and the sliding frame 220. When the threaded rod 240 is rotated to move the round block 250 downward and release it from the pressure on the outer shell of the power distribution cabinet body 100, the threaded rod 240 and the sliding rod 230 still maintain a threaded connection.
[0030] It should be noted that, since the opening of the limiting groove 110 faces downward and there is a certain distance between the limiting groove 110 and the edge of the outer shell of the power distribution cabinet body 100, the limiting groove 110 is not protected.
[0031] like Figure 2 , Figure 3 and Figure 4 As shown, a protective plate 260 is fixedly connected to one side of the rain shelter 210. The protective plate 260 has a flat-topped cone shape, and a through groove 261 is formed on the inner wall of the protective plate 260. The through groove 261 is inclined, and its higher end is connected to a drainage groove. The horizontal height of the top of the protective plate 260 is higher than that of the top of the rain shelter 210, and the horizontal height of the bottom of the protective plate 260 is lower than that of the bottom of the rain shelter 210.
[0032] In this embodiment, when the rain shield 210 is retracted into the outer shell of the power distribution cabinet body 100, the side of the protective plate 260 near the outer shell of the power distribution cabinet body 100 is in contact with the surface of the outer shell of the power distribution cabinet body 100, thereby protecting the opening of the outer shell of the power distribution cabinet body 100 where the rain shield 210 is installed.
[0033] like Figure 3 and Figure 4 As shown, a first magnetic plate 120 is embedded in the front end of the outer shell of the power distribution cabinet body 100, and a second magnetic plate 262 is embedded in the side of the protective plate 260 near the outer shell of the power distribution cabinet body 100.
[0034] In this embodiment, the first magnetic plate 120 and the second magnetic plate 262 are located on the same horizontal plane, and the magnetic poles of the opposite sides of the first magnetic plate 120 and the second magnetic plate 262 are opposite. Therefore, when one side of the protective plate 260 is attached to the surface of the outer shell of the power distribution cabinet body 100, the opposite sides of the first magnetic plate 120 and the second magnetic plate 262 attract each other, thereby limiting the protective plate 260 and the rain shield 210.
[0035] like Figure 5 As shown, a round pad 251 is fixedly connected to the top of the round block 250. The round pad 251 is a rubber component and has multiple grooves distributed in a ring.
[0036] In this embodiment, when the top of the circular block 250 is pressed against the surface of the outer shell of the power distribution cabinet body 100, the surface of the circular pad 251 is pressed against the surface of the outer shell of the power distribution cabinet body 100.
[0037] Working principle: In rainy weather, when the rain shield 210 needs to be slid out from the outer shell of the distribution cabinet 100 to protect it from rain, the operator rotates the threaded rod 240 to move the round block 250 downward, thereby releasing it from the contact with the outer shell surface of the distribution cabinet 100. After release, the operator pulls the threaded rod 240 to move it within the limiting groove 110. At the same time, the operator assists in releasing the attraction between the first magnetic plate 120 and the second magnetic plate 262, so that the threaded rod 240 moves synchronously with the sliding rod 230 and the sliding frame 220. Under the action of the slider 221 and the spring 222, the rain shield 210 is moved. The screw rod 240 moves synchronously and slides out of the outer shell of the distribution cabinet body 100. When the screw rod 240 can no longer move, the rain shield 210 can complete the movement and start the rain shielding operation. At this time, when the screw rod 240 is rotated in the opposite direction, the round block 250 abuts against the surface of the outer shell of the distribution cabinet body 100 again, thereby limiting the sliding rod 230, the sliding frame 220 and the rain shield 210. During the rain shielding process, when the rain shield 210 is hit, the rain shield 210 will squeeze the spring 222 and move into the outer shell of the distribution cabinet body 100. After the collision is released, the rain shield 210 will automatically reset under the action of the spring 222 to start the rain shielding operation.
[0038] When it is necessary to retract the rain shield 210 into the outer shell of the distribution cabinet body 100, after releasing the fixing of the round block 250 to the outer shell of the distribution cabinet body 100, the reverse movement of the threaded rod 240 can drive the rain shield 210 into the outer shell of the distribution cabinet body 100 through the slide rod 230, slide frame 220, spring 222 and slider 221.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
