Description

An instrument panel for a prefabricated substation Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and more specifically to an instrument panel for prefabricated substations. Background Technology

[0002] Prefabricated substations have replaced traditional civil engineering power distribution rooms and substations, becoming a new type of complete power distribution device. They are suitable for residential communities, urban public utilities, bustling city centers, construction power supplies, mines, factories, oil and gas fields, and wind power stations. Users can choose prefabricated substations according to different usage conditions and load levels.

[0003] The prefabricated substation has a fixed instrument panel with various instruments mounted on it. The connection between the instrument panel and the instruments usually involves making multiple threaded holes in the instrument panel, aligning the through holes on the lugs around the instruments with individual threaded holes, and then screwing bolts through the lugs and into the instrument panel to position each instrument sequentially. However, this method has drawbacks. During installation, the instruments need to be straightened to ensure that the through holes around the instruments are connected to the corresponding threaded holes. If not straightened, when tightening the first bolt, the instrument will rotate downwards and swing relative to the bolt, causing the wiring connected to the instrument to become tangled and intertwined, affecting the installation efficiency. During disassembly, because the instrument panel already has several relatively compact instruments, it is difficult for maintenance personnel to straighten it. If an instrument swings downwards, it may collide with adjacent instruments and be damaged, and it will also exacerbate the bending and breakage of the wiring, affecting the subsequent reuse of the wiring. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an instrument panel that can ensure the stability of the instrument state and improve the disassembly and assembly efficiency during the disassembly and assembly process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an instrument panel for a prefabricated substation, comprising a panel and a plurality of instruments all positioned on the panel, and further comprising a plurality of support members for supporting the instruments. The panel is provided with insertion holes located below the plurality of instruments for the support members to be inserted. By inserting the support members into the panel, the instruments are supported by the support members during assembly and disassembly.

[0006] As a further improvement of this utility model, each of the several support members includes an insert plate that can be inserted into the socket, a redundant column positioned on the upper surface of the insert plate, and a support plate positioned on the upper end of the redundant column for supporting the instrument. The length of the insert plate is greater than the length of the support plate, and there is a gap between the support plate and the plate body. The insert plate is provided with a plurality of wire-passing openings distributed along the length direction of the insert plate, and one end of the plurality of wire-passing openings extends to the edge of the insert plate in the width direction.

[0007] As a further improvement of this utility model, a limiting foot that can contact the surface of the plate is provided below the insert plate.

[0008] As a further improvement of this utility model, a force-bearing strip for traction is provided at the bottom edge of the insert plate away from the plate body.

[0009] As a further improvement of this utility model, the upper surface of the support plate is provided with a downwardly recessed arc groove located in the middle of the support plate.

[0010] As a further improvement of this utility model, the number of sockets located below the same instrument is two to three and they are vertically distributed.

[0011] The beneficial effects of this utility model are as follows: By inserting a support member into the plate, the instrument is supported by the support member during disassembly and assembly. Compared with the prior art, this design can provide an effective support during disassembly and assembly, avoid the instrument from swinging unexpectedly, indirectly improve the disassembly and assembly efficiency and the stability of the instrument, and at the same time reduce the occurrence of collisions between adjacent instruments.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0018] Referring to Figures 1 to 4, an instrument panel for a box-type substation in this embodiment includes a plate 1 and a plurality of instruments 2 all positioned on the plate 1. The plate 1 is provided with a plurality of threaded holes. The instrument 2 is integrally formed with lugs around its periphery. The lugs are provided with through holes. The instrument 2 is connected to the plate 1 by connecting the through holes with the threaded holes of the plate 1 and by bolting.

[0019] Based on the aforementioned prior art, multiple insertion holes 4 are machined on the plate 1, each located below multiple instruments 2. The insertion holes 4 are elongated and parallel to the horizontal plane in the length direction. The plate 1 also includes several support members 3. Each support member 3 includes an integrally formed insertion plate 31, a redundant post 32, and a support plate 33. The insertion plate 31 matches the insertion holes 4. The redundant post 32 is positioned on the upper surface of the insertion plate 31 and is located in the middle of the length direction of the insertion plate 31. The support plate 33 is positioned at the top of the redundant post 32. The support plate 33 and the redundant post 32 together form a T-shape. Multiple wire-passing openings 34 distributed along the length direction of the insertion plate 31 are machined inward from the edge of the insertion plate 31 away from the support plate 33.

[0020] During the installation of instrument 2, move instrument 2 roughly to the desired installation position. The wires on the lower surface of instrument 2 are close to the plate 1. Select a support 3 of appropriate size, align the wire-passing openings 34 with the different wires, and then insert the plug plate 31 into the socket 4. After the plug plate 31 is inserted, the width of the plug plate 31 protruding from the surface of the plate 1 is greater than the width of the support plate 33. There is a gap between the support plate 33 and the surface of the plate 1 for the power supply wires to pass through. The multiple wires under instrument 2 are confined within different wire-passing openings 34. Then, place the lower end of instrument 2 on the support plate 33, then attach instrument 2 to the plate 1 and move it horizontally so that the through holes around instrument 2 correspond one by one with the threaded holes on the plate 1. Finally, use bolts to position instrument 2. On board 1, connect the wires below instrument 2 to the corresponding external connections. If you want to install another instrument 2, pull out the support 3 below the already installed instrument 2 and insert it into the socket 4 at the location of the instrument 2 to be installed. During the disassembly of instrument 2, insert the support 3 into the socket 4 below the instrument 2 to be disassembled. The multiple wire harnesses below instrument 2 are respectively confined in multiple wire-passing openings 34. The lower surface of instrument 2 is in contact with the support plate 33. Then, the worker gently pushes instrument 2 with one hand and unscrews the bolts one by one with the other hand. Finally, remove instrument 2 and remove support 3. To further explain, support 3 can also be left in place after installation. Support 3 can continuously support instrument 2 and prevent the bolts from bending downwards due to the large weight of instrument 2.

[0021] Compared with existing technologies, this design provides effective support during the assembly and disassembly of instrument 2, preventing accidental swinging of instrument 2, indirectly improving the assembly and disassembly efficiency and stability of instrument 2, and reducing the chance of collisions between adjacent instruments 2; the wiring harness connected to instrument 2 is separated and limited by multiple wire-passing openings 34, which facilitates the classification of wiring harnesses and makes subsequent external connection more convenient, avoiding the situation of wiring harnesses getting tangled; the design of switching the same support component 3 to different positions of the socket 4 can reduce the number of support components 3 used, thereby reducing the cost of use.

[0022] As an improved specific implementation, as shown in FIG4, a pair of limiting feet 35 are integrally formed on the lower surface of the insert plate 31. When the insert plate 31 is inserted into the insertion hole 4, the pair of limiting feet 35 contact the surface of the plate body 1. This design can limit the length of the insert plate 31 inserted into the insertion hole 4, thereby improving the accuracy of the insertion of the insert plate 31.

[0023] As an improved specific implementation, referring to FIG4, a force-bearing strip 36 is integrally formed below the insert plate 31. The force-bearing strip 36 is located at the edge of the insert plate 31 away from the plate body 1. The worker can apply traction force to the force-bearing strip 36 with his / her fingers or hooks to drive the support member 3 out of the insertion hole 4. This design can provide the worker with an effective force application point and facilitate the disassembly of the support member 3.

[0024] As an improved implementation, the lower surface of instrument 2 is not entirely flat. In some cases, the lower surface of instrument 2 is an arc surface that protrudes downwards. In this case, instrument 2 will swing relative to support plate 33 and cannot be aligned, resulting in a decrease in the installation efficiency of instrument 2. To solve the aforementioned problem, as shown in Figure 4, an arc groove 37 is machined on the upper surface of support plate 33, which is recessed into support plate 33 and located in the middle of support plate 33. By extending the protruding part below instrument 2 into arc groove 37, the lower surface of instrument 2 touches the opening edge of arc groove 37 or the lower surface of instrument 2 completely matches arc groove 37. Then, instrument 2 is accurately positioned relative to support plate 33, which facilitates the installation of instrument 2. This design can increase the applicability of support component 3.

[0025] As an improved specific implementation, since there are various situations where the vertical distance between the bottom surface of the instrument 2 and the lug can be different, there is a situation where the bottom of the instrument 2 blocks the socket 4, resulting in the instrument 2 not being able to be supported. To solve the aforementioned problem, referring to Figures 1 and 2, according to actual needs, multiple vertically distributed sockets 4 are processed under the same instrument 2. The number of sockets 4 is two to three. Workers can insert support members 3 into the sockets 4 at different heights so that the support members 3 can effectively support instruments 2 of different specifications, further increasing the applicability of this utility model. At the same time, compared with designing support members 3 of different specifications, it can reduce processing costs and usage costs.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
