Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, and more specifically, to a dustproof box-type transformer substation. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines transformer step-down, low-voltage distribution and other functions organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation.

[0003] At present, most box-type substations are installed outdoors. Considering the ventilation and heat dissipation of the box-type substation, ventilation holes are often opened on the side walls and filters are installed. For example, a box-type substation with dust-proof and heat-dissipating functions is disclosed in a Chinese patent with a publication (announcement) number of CN210053082U. It includes a box-type substation body, a filter plate is fixedly arranged in the middle of the inner cavity of the top seat, a micro-circulation pump is fixedly arranged on the left side of the bottom of the top seat, and heat-absorbing plates are evenly and equidistantly arranged on the outer wall of the bottom of the cooling pipe. Step holes are opened on both sides of the box-type substation body, and dust screens with the same structure are fixedly arranged in the step holes. The dust screen includes a fixing ring, which is fixed to the step end face of the step hole by fixing screws, and a dust screen is fixedly arranged on the inner wall of the fixing ring; because the dust screen adheres to the dust blocking the mesh after long-term use, it needs to be disassembled and cleaned, but the fixing ring is fixedly installed by fixing screws, which makes it inconvenient to disassemble the fixing ring and the dust screen. At the same time, it is easy to be stolen or damaged by naughty children if it is directly installed on the outside of the box-type substation body. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 As shown, a dustproof box-type substation of an embodiment of the utility model includes a box-type substation body 1, a plurality of box doors 2 are hinged on the front side of the box-type substation body 1, a heat dissipation window 20 is opened at the lower part of each box door 2, a dustproof frame 3 is installed on the front side of the heat dissipation window 20, and a dustproof screen 30 is built in the dustproof frame 3, and the dustproof screen 30 is detachably connected to the box door 2 through a clamping assembly.

[0022] When in use, the heat dissipation window 20 is provided to facilitate the interaction of air inside and outside the box-type substation body 1, thereby ensuring its ventilation and heat dissipation effect. The dust-proof frame 3 and the dust-proof net prevent the dust outside the box-type substation body 1 from entering the inside through the heat dissipation window 20, thereby ensuring the dust-proof effect.

[0023] The dustproof frame 3 is detachably connected to the box door 2 by a clamping assembly to ensure its convenience in assembly and disassembly. The detachable connection of the dustproof frame 3 is convenient for daily replacement and daily cleaning and maintenance of the internal dustproof screen 30. The clamping assembly is located on the inner side of the box door 2, so the dustproof frame 3 can be disassembled and assembled only when the box door 2 is opened, thereby preventing the dustproof frame 3 from being stolen or damaged by naughty children during daily use.

[0024] Two first limiting members 21 are correspondingly arranged on the left side of the heat dissipation window 20 on the front side of the box door 2, and two second limiting members 22 are arranged on the right side of the heat dissipation window 20 on the front side of the box door 2. When the dustproof frame 3 is in the installed state, the four corners thereof are limited by the two first limiting members 21 and the two second limiting members 22; the first limiting member 21 is in an "L"-shaped structure and its vertical surface faces the heat dissipation window 20, and an installation slot 23 is provided on the inner side of the first limiting vertical surface, and an installation interval adapted to the dustproof frame 3 is formed between the installation slot 23 and the outer surface of the box door 2; the second limiting member 22 is in an "I"-shaped structure, and a limiting through groove 24 is provided at the inner ends of the opposite sides of the two second limiting members 22, and limiting ribs 25 adapted to the limiting through groove 24 are provided at the right ends of the upper and lower sides of the dustproof frame 3.

[0025] During use, when installing the dustproof frame 3, first fit the dustproof frame 3 to the front side of the box door 2, and then control the dustproof frame 3 to slide to the left along the front side of the box door 2, so that the two right-angle ends on the left side of the dustproof frame 3 respectively enter the installation slots 23 of the two first limiting members 21, and at the same time, the two limiting ribs 25 of the dustproof frame 3 respectively enter the limiting grooves 24 of the two second limiting members 22, and the four corners of the dustproof frame 3 are limited by the two first limiting members 21 and the two second limiting members 22 to ensure the installation stability of the dustproof frame 3.

[0026] The clamping assembly includes a clamping plate 31 arranged at the left end of the inner side of the dustproof frame 3. The clamping plate 31 is in an "L"-shaped structure and the lateral end is connected to the dustproof frame 3. A clamping groove 32 is provided at the vertical end of the clamping plate 31. A accommodating groove 33 is provided on the inner side of the box door 2 at the matching position of the clamping groove 32, and a clamping block 34 is telescopically arranged in the accommodating groove 33; a spring member 35 is built into the accommodating groove 33, and the two ends of the spring member 35 are respectively fixedly connected to the clamping block 34 and the inner bottom wall of the accommodating groove 33; the clamping block 34 is provided with a guiding waist 36 on the side facing the heat dissipation window 20.

[0027] When in use, when installing the dustproof frame 3, the dustproof frame 3 is fitted with the front side of the door 2. At this time, the clamping plate 31 inside the dustproof frame 3 extends into the heat dissipation window 20, and then the dustproof frame 3 is controlled to slide leftward along the front side of the door 2. While the four corners of the dustproof frame 3 are clamped with the first limiting members 21 and the second limiting members 22, the clamping plate 31 reaches the specified position and forms a limiting clamping with the clamping block 34, completing the installation and locking of the dustproof frame 3.

[0028] The specific cooperation process between the clamping plate 31 and the blocking block 34 is that the clamping plate 31 slides and contacts the guiding oblique waist 36. At this time, the clamping plate 31 continues to push inwards and cooperates with the guiding oblique waist 36 to cause the blocking block 34 to retract into the accommodating groove 33. When the blocking block 34 retracts, the spring member 35 is compressed and the spring member 35 is in an energy storage state. Then the clamping plate 31 continues to move and makes the position of the blocking groove 32 coincide with the accommodating groove 33. At this time, the blocking block 34 pops out of the accommodating groove 33 due to the energy release of the spring member 35 and forms a limited clamp with the blocking groove 32, completing the installation and locking of the dustproof frame 3; when the dustproof frame 3 needs to be further disassembled, the box door 2 is opened and the blocking block 34 is pushed into the accommodating groove 33 until the limited clamp between the blocking block 34 and the blocking groove 32 disappears, and the dustproof frame 3 can be pulled out.

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
