Description
Technical Field
[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a sealed high and low voltage power distribution cabinet suitable for multiple locations. Background Art
[0002] As the name implies, high- and low-voltage distribution cabinets are power distribution equipment used for power distribution, control, metering, and cable connection within power supply systems. Power supply bureaus and substations typically use high-voltage switchgear. The power is then stepped down by a transformer on the low-voltage side and then routed to low-voltage distribution cabinets. The low-voltage distribution cabinets then route power to the various power distribution panels, control boxes, and switch boxes. In existing technologies, the bottom of distribution cabinets is directly in contact with the ground. When the air is humid, the internal operating temperature of the distribution cabinet is high, which can easily lead to water droplets forming on the bottom, posing a safety hazard.
[0003] Chinese patent CN201911102681.1 discloses a moisture-proof structure for the bottom of an electric power distribution cabinet and its working method. The humidity at the bottom of the distribution cabinet is monitored by a humidity controller, and the push rod motor is used to control the overall upward movement of the cabinet to increase the distance between the bottom of the distribution cabinet and the ground. The moisture at the bottom of the distribution cabinet is absorbed and processed by a moisture-proof component. However, during use, the push rod motor pushes the cabinet to move multiple times, which not only causes the cables connecting the cabinet to the outside world to be pulled and rubbed, thereby causing the cables to be damaged or unable to work normally, but also the movement of the cabinet itself is dangerous and may cause it to topple over.

[0043] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] like Figures 1 to 10 As shown, this application provides:
[0045] A closed high and low voltage distribution cabinet suitable for multiple locations, including a main cabinet body 1, a bottom cabinet 2, a moving component 3, a heating component 4 and a sponge board 5. The bottom cabinet 2 is fixedly arranged below the main cabinet body 1, and two mutually parallel sides of the bottom cabinet 2 are provided with air vents 2a. The moving component 3 includes a U-shaped frame 3a, a positioning block 3b and a first limiting bolt 3c. The U-shaped frame 3a is slidably arranged inside the bottom cabinet 2. Both ends of the bottom cabinet 2 with the air vents 2a are provided with U-shaped frames 3a. The sliding direction of the U-shaped frame 3a is parallel to the height direction of the bottom cabinet 2. The two raised ends of the U-shaped frame 3a are arranged downward. The positioning block 3b is fixedly arranged at the end of the raised end of the U-shaped frame 3a. The first limiting bolt 3c is threadedly matched with the U-shaped frame 3a and the positioning block 3b. The bottom cabinet 2 is provided with a screw thread that cooperates with the first limiting bolt 3c. The first long chute 2b, the length direction of the first long chute 2b is equal to the height direction of the base cabinet 2, the heating component 4 includes a fixed plate 4a, a first spring 4b, a pressure sensor 4c and a heating plate 4d, the fixed plate 4a is fixedly set on the inner bottom surface of the base cabinet 2, the number of fixed plates 4a is equal to the U-shaped frame 3a and each fixed plate 4a is set directly below the U-shaped frame 3a, the first spring 4b is set between the fixed plate 4a and the U-shaped frame 3a, the axis of the first spring 4b is parallel to the height direction of the base cabinet 2, the pressure sensor 4c is set on the side of the fixed plate 4a close to the U-shaped frame 3a, the pressure sensor 4c is set below the positioning block 3b, the heating plate 4d is set at the center of the side of the fixed plate 4a close to the U-shaped frame 3a, and the sponge plate 5 is set between the two moving components 3.
[0046] Based on the above embodiments, the technical problem that this application aims to solve is that the push rod motor pushes the cabinet to move multiple times during use. This will not only cause the cables connecting the cabinet to the outside world to be pulled and rubbed, thereby causing the cables to be damaged or unable to work normally, but also the movement of the cabinet itself will cause the cabinet to tip over. To this end, the present application allows the moisture on the bottom to first contact the sponge board 5 during the process of moving upward. After absorbing the moisture, the weight of the sponge board 5 increases and moves away from the main cabinet 1, thereby preventing the moisture from contacting the main cabinet 1. Then, when the weight of the sponge board 5 reaches a set threshold, the signal transmitted by the pressure sensor 4c will cause the heating plate 4d to work, so that the sponge board 5 is continuously heated at both ends near the ventilation hole. After the moisture is evaporated, it moves along the ventilation hole to the outside of the bottom cabinet 2. Compared with the prior art, the bottom cabinet 2, U-shaped frame 3a, positioning block 3b, first limit bolt 3c, fixing plate 4a, first spring 4b, pressure sensor 4c, heating plate 4d and sponge board 5 of the present application cooperate with each other to effectively prevent moisture from contacting the main cabinet 1 while keeping various facilities in the main cabinet 1 from moving.
[0047] Further, such as Figures 8 to 10 As shown:
[0048] A first guide column 4a1 is provided on the fixing plate 4a, and the axis of the first guide column 4a1 is parallel to the height direction of the base cabinet 2. A first guide hole 3a1 cooperating with the first guide column 4a1 is opened on the U-shaped frame 3a, and the two ends of the first spring 4b are respectively connected to the first guide column 4a1 and the first guide hole 3a1.
[0049] Based on the above embodiments, the technical problem that this application aims to solve is that the first spring 4b may not be correctly compressed and extended during operation. To this end, this application connects the two ends of the first spring 4b to the first guide post 4a1 and the first guide hole 3a1, respectively, to ensure the direction of the elastic force of the first spring 4b. Compared with the prior art, the first guide post 4a1 and the first guide hole 3a1 of the present application define the direction of the elastic force of the first spring 4b.
[0050] Further, such as Figures 6 to 9 As shown:
[0051] The movable assembly 3 also includes a movable strip 3d and a second limiting bolt 3e. The movable strip 3d is slidably set in the U-shaped frame 3a. The sliding direction of the movable strip 3d is parallel to the height direction of the cabinet. The second limiting bolt 3e is fixedly set at both ends of the movable strip 3d. The U-shaped frame 3a is provided with a second long strip sliding groove that cooperates with the second limiting bolt 3e. The length direction of the second long strip sliding groove is parallel to the sliding direction of the U-shaped frame 3a.
[0052] Based on the above embodiment, the technical problem that this application aims to solve is that the sponge board 5 will wobble as it moves with the U-shaped frame 3a when it has not absorbed enough moisture. To this end, this application provides a movable strip 3d above the sponge board 5 to prevent wobble when it moves. Compared with the prior art, the movable strip 3d and the second limiting bolt 3e of this application limit the sliding state of the sponge board 5.
[0053] Further, such as Figures 8 and 9 As shown:
[0054] The moving assembly 3 further includes a second spring 3f, which is disposed between the movable strip 3d and the U-shaped frame 3a. The axis of the second spring 3f is parallel to the sliding direction of the movable strip 3d.
[0055] Based on the above embodiment, the technical problem that this application aims to solve is that the movable strip 3d may become stuck and unable to work properly during the reciprocating movement of the U-shaped frame 3a. To this end, the present application uses a second spring 3f to provide elastic force to push the movable strip 3d to always maintain contact with the sponge board 5. Compared with the existing technology, the second spring 3f of the present application ensures that the movable strip 3d always maintains a normal working state.
[0056] Further, such as Figures 8 and 9 As shown:
[0057] A second guide column 3d1 is provided on the movable strip 3d, and the axis of the second guide column 3d1 is parallel to the sliding direction of the movable strip 3d. A second guide hole 3a2 is provided on the U-shaped frame 3a to cooperate with the second guide column 3d1. The two ends of the second spring 3f are respectively connected to the second guide column 3d1 and the second guide hole 3a2.
[0058] Based on the above embodiments, the technical problem that this application aims to solve is that the second spring 3f may not be correctly compressed and extended during operation. To this end, this application connects the two ends of the second spring 3f to the second guide post 3d1 and the second guide hole 3a2, respectively, to ensure the direction of the elastic force of the second spring 3f. Compared with the prior art, the second guide post 3d1 and the second guide hole 3a2 of the present application define the direction of the elastic force of the second spring 3f.
[0059] Further, such as Figure 6 and Figure 8 As shown:
[0060] The second limiting bolt 3e extends to the outside of the U-shaped frame 3a, and the second limiting bolt 3e is movably engaged with the first long sliding groove 2b.
[0061] Based on the above embodiment, the technical problem that this application aims to solve is that the U-shaped frame 3a may rotate during movement. To this end, this application uses the first limiting bolt 3c and the second limiting bolt 3e to cooperate with the first long slide 2b to ensure the sliding state of the U-shaped frame 3a. Compared with the existing technology, the second limiting bolt 3e of this application cooperates with the first long slide 2b to provide a second limit to the U-shaped frame 3a.
[0062] Further, such as Figures 8 and 9 As shown:
[0063] A trapezoidal groove 3d2 is formed on the movable strip 3d. The trapezoidal groove 3d2 is arranged at one end close to the ventilation hole, and the inclined surface of the trapezoidal groove 3d2 is arranged at a position away from the ventilation hole.
[0064] Based on the above embodiment, the technical problem that this application aims to solve is that the presence of the movable strip 3d causes the evaporated water vapor to be directly blocked by the movable strip 3d. To this end, this application provides a trapezoidal groove 3d2 to guide the evaporated water vapor to move to the vent 2a. Compared with the existing technology, the movable strip 3d of this application provides a trapezoidal groove 3d2 to allow the evaporated water vapor to move normally to the vent 2a.
[0065] Further, such as Figures 6 and 7 As shown:
[0066] The base cabinet 2 includes a shell 2c and a movable plate 2d. The movable plate 2d is connected to the shell 2c by bolts. The movable plate 2d and the shell 2c are rotatably matched. The movable plate 2d is arranged on a side of the shell 2c away from the U-shaped frame 3a.
[0067] Based on the above embodiment, the technical problem that the present application aims to solve is that the water absorption capacity of the sponge board 5 is poor after repeated use. To this end, the present application allows the staff to quickly replace the sponge board 5 inside the base cabinet 2 by simply unscrewing the bolts. Compared with the prior art, the shell 2c and the movable plate 2d of the present application cooperate with each other so that the staff can quickly replace the sponge board 5 inside the base cabinet 2.
[0068] Further, such as Figures 5 to 7 As shown:
[0069] The length of the ventilation hole is equal to the length of the movable strip 3d, the width of the ventilation hole is smaller than the width of the movable strip 3d, the number of the ventilation holes is several, and all the ventilation holes are evenly arranged along the height direction of the bottom cabinet 2.
[0070] Based on the above embodiments, the technical problem that this application aims to solve is that excessively large ventilation holes may cause debris to enter the base cabinet 2 and affect normal operation. To this end, this application limits the size, number, and position of the ventilation holes to ensure normal operation without the entry of debris. Compared with the existing technology, the base cabinet 2 of this application, by limiting the size, number, and position of the ventilation holes, ensures that debris cannot enter the interior of the base cabinet 2.
[0071] Further, such as Figures 6 and 7 As shown:
[0072] The base cabinet 2 further includes shielding plates 2e, which cooperate with the ventilation holes. The number of the shielding plates 2e is equal to the number of the ventilation holes and the positions thereof correspond one to one.
[0073] Based on the above embodiment, the technical problem that this application aims to solve is that on rainy days, rainwater will enter through the ventilation holes and increase the working pressure of the sponge board 5. To this end, this application uses a shielding plate 2e to block rainwater from entering the cabinet body. Compared with the existing technology, the shielding plate 2e of this application prevents water from the external natural environment from entering the base cabinet 2 and affecting the operation of the sponge board 5.
[0074] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
