Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a prefabricated box-type substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution unit that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] To ensure proper heat dissipation, existing prefabricated box-type substations typically require ventilation holes on their side walls. Furthermore, to prevent external dust from entering the substation, dustproof mesh panels are installed over these ventilation holes. However, these mesh panels can become clogged over time, hindering proper heat dissipation. For example, utility model patent CN213959541U discloses a prefabricated box-type substation that utilizes a dustproof mesh embedded in the inner wall of a through-hole on one side of a first grid plate and a dustproof mesh embedded in the inner wall of a heat dissipation hole on one side of a second grid plate. This design helps reduce dust and condensation buildup inside the substation.

[0004] However, the dustproof net of this prefabricated box-type substation is embedded in the inner wall of the through holes and heat dissipation holes of the box body, making it inconvenient to disassemble and clean the dustproof net.

[0005] Therefore, it is necessary to develop a prefabricated box-type substation to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated box-type substation that facilitates the disassembly and cleaning of dustproof nets, avoids dustproof net blockage, and ensures normal ventilation and heat dissipation of the substation.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a prefabricated box-type substation, including a substation enclosure. Mounting grooves are formed on both side walls of the enclosure, and several heat dissipation holes are formed through the bottom surface of each mounting groove. A dustproof component is embedded within the mounting groove. A protective cover is detachably connected to the end of the dustproof component away from the heat dissipation holes. Limiting components are provided on both sides of the mounting grooves to fix the protective cover to the outer side wall of the substation enclosure. A cleaning component is fixedly connected to one side of the protective cover for cleaning the dustproof component.

[0009] Furthermore, the dustproof component includes a dustproof net and a dustproof net frame, the dustproof net being fixedly connected inside the dustproof net frame; the dustproof net frame is fitted into the mounting groove, one side of the dustproof net frame is in contact with the bottom surface of the mounting groove and the other side is on the same vertical plane as the outer surface of the substation box.

[0010] Furthermore, the protective cover includes a mounting frame and several louver blades. The several louver blades are arranged vertically and hinged to the inner walls on both sides of the mounting frame. The side wall of the mounting frame near the dustproof mesh frame is in contact with the side wall of the substation box.

[0011] Furthermore, the limiting component includes a support plate, which is horizontally fixedly connected to the outer wall of the substation enclosure below the mounting slot. The support plate has several slots, and compression springs are fixedly connected to the bottom surface of the slots. A water storage tank is fixedly connected to the outer wall of the substation enclosure above the mounting slot, and several flow guide holes are opened on the bottom surface of the water storage tank. Several elastic support columns corresponding to and adapted to the slots are fixedly connected to the bottom surface of the mounting frame, and several flow guide pipes corresponding to and adapted to the flow guide holes are fixedly connected to the top surface of the mounting frame. The mounting frame is limited and fixed by inserting the support columns and the flow guide pipes into the slots and the flow guide holes respectively.

[0012] Furthermore, the support column is specifically made of polyurethane rod.

[0013] Furthermore, the cleaning assembly includes a movable plate and two sliding rods. The two sliding rods are horizontally fixedly connected to both ends of the two inner walls of the mounting frame. The two ends of the movable plate are slidably connected to the two sliding rods. A brush is fixedly connected to the end of the movable plate near the dustproof net, and the brush is in contact with the dustproof net. A pull rod is fixedly connected to the middle of one side wall of the movable plate. The pull rod is horizontally arranged along the direction of the sliding rod and one end penetrates the mounting frame. A handle is fixedly connected to the end face of the pull rod penetrating the mounting frame.

[0014] Furthermore, the guide pipe penetrates the top plate of the mounting frame, and a guide plate is inclinedly arranged directly below the guide pipe. The two ends of the guide plate are respectively fixedly connected to the two inner side walls of the top of the mounting frame. The guide plate is inclined towards the dustproof net and one end is in contact with the dustproof net.

[0015] Furthermore, a water-permeable hole is provided at the bottom of the dustproof mesh frame, and a drainage groove is provided on the bottom surface of the mounting groove, with both ends of the drainage groove penetrating the substation box.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This invention embeds the dustproof component into a mounting groove and secures it within the groove using a protective cover. A limiting component then fixes the protective cover to the side wall of the substation enclosure. Disassembly of the dustproof component is simple: just open the limiting component, remove the protective cover, and take the dustproof component out of the mounting groove. This facilitates the installation and removal of the dustproof screen. Furthermore, a cleaning component allows for dust removal and cleaning of the dustproof screen without disassembling the component, preventing clogging and ensuring proper ventilation and heat dissipation in the substation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In one specific implementation, such as Figures 1-4 As shown, the system includes a substation enclosure 1. Mounting grooves 2 are provided on both side walls of the substation enclosure 1. Several heat dissipation holes 3 are provided through the bottom surface of the mounting grooves 2. A dustproof component 4 is embedded within the mounting grooves 2. A protective cover 5 is detachably connected to the end of the dustproof component 4 away from the heat dissipation holes 3. The protective cover 5 is in contact with the dustproof component 4 and is fixed within the mounting groove 2. Limiting components 6 are provided on both sides of the mounting groove 2. The limiting components 6 are used to fix the protective cover 5 to the outer side wall of the substation enclosure 1. A cleaning component 7 is fixedly connected to one side of the protective cover 5. The cleaning component 7 is used to clean the dustproof component 4.

[0028] In one specific embodiment, the dustproof component 4 includes a dustproof net 401 and a dustproof net frame 402. The dustproof net 401 is fixedly connected inside the dustproof net frame 402. The dustproof net frame 402 is fitted into the mounting groove 2. One side of the dustproof net frame 402 is in contact with the bottom surface of the mounting groove 2 and the other side is on the same vertical plane as the outer side of the substation box 1.

[0029] Specifically, the protective cover 5 includes a mounting frame 501 and several louver blades 502. The several louver blades 502 are arranged vertically and hinged to the inner walls on both sides of the mounting frame 501, which can prevent rainwater from entering the substation box 1 through the dustproof net 401 and the heat dissipation hole 3 under the action of wind. One side wall of the mounting frame 501 is respectively in contact with the dustproof net frame 402 and the substation box 1, which can fix the dustproof net frame 402 in the mounting groove 2.

[0030] Specifically, the limiting component 6 includes a support plate 601, which is horizontally fixed to the outer wall of the substation enclosure 1 below the mounting slot 2. The support plate 601 has several slots 602, and a compression spring 603 is fixedly connected to the bottom surface of the slots 602. A water storage tank 604 is fixedly connected to the outer wall of the substation enclosure 1 above the mounting slot 2. The bottom surface of the water storage tank 604 has several guide holes 605. The bottom surface of the mounting frame 501 has several elastic support columns 606 that correspond one-to-one with and are adapted to the slots 602. The top surface of the mounting frame 501 has several guide pipes 607 that correspond one-to-one with and are adapted to the guide holes 605. The guide pipes 607 are stainless steel pipes. The mounting frame 501 is limited and fixed by inserting the support columns 606 and the guide pipes 607 into the slots 602 and the guide holes 605 respectively.

[0031] By inserting the support column 606 at the bottom of the mounting frame 501 into the slot 602, and then pressing down to compress the compression spring 603 until the top of the guide pipe 607 is lower than the bottom surface of the water storage tank 604, the mounting frame 501 is pressed towards the side wall of the substation enclosure 1, so that the mounting frame 501 contacts the dustproof mesh frame 402 and the side wall of the substation enclosure 1. Then, the mounting frame 501 is released, and under the restoring force of the compression spring 603, the mounting frame 501 moves upward to insert the guide pipe 607 into the guide hole 605, thereby fixing the protective cover to the side wall of the substation enclosure 1.

[0032] Specifically, the support column 606 is made of polyurethane rod. The support column 606 on the mounting frame 501 can be bent when inserted into the slot 602, which facilitates the installation of the mounting frame 501.

[0033] Specifically, the cleaning component 7 includes a movable plate 701 and two sliding rods 702. The two sliding rods 702 are horizontally fixed to both ends of the two inner walls of the mounting frame 501. The two ends of the movable plate 701 are slidably connected to the two sliding rods 702. A brush 703 is fixedly connected to one end of the movable plate 701 near the dustproof net 401. The brush 703 is in contact with the dustproof net 401. A pull rod 704 is fixedly connected to the middle of one side wall of the movable plate 701. The pull rod 704 is horizontally arranged along the direction of the sliding rods 702 and one end penetrates through the mounting frame 501. A handle 705 is fixedly connected to the end face of the pull rod 704 penetrating through the mounting frame 501.

[0034] By pulling the handle 705, the moving plate 701 slides on the slide bar 702, causing the brush 703 to brush over the surface of the dustproof mesh 401, thus achieving dust cleaning without disassembling the filter.

[0035] Specifically, the guide pipe 607 penetrates the top plate of the mounting frame 501, and a guide plate 706 is inclinedly arranged directly below the guide pipe 607. The two ends of the guide plate 706 are fixedly connected to the two inner side walls of the top of the mounting frame 501, and the guide plate 706 is inclined towards the dustproof net 401 and one end is in contact with the dustproof net 401.

[0036] When cleaning the dustproof net 401 using the cleaning component 7, cleaning solution or water is added to the water storage tank 604. The cleaning solution is guided through the guide pipe 607 and the guide plate 706 to flow to the dustproof net 401, enhancing the cleaning effect of the dustproof net 401 in conjunction with the cleaning component 7. Simultaneously, in rainy weather, the water storage tank 604 can collect rainwater, which, through the action of the guide pipe 607 and the guide plate 706, is guided to wash the dustproof net 401, achieving self-cleaning of the dustproof net 401.

[0037] Specifically, a water passage hole 707 is provided through the bottom end of the dustproof mesh frame 402, and a drainage groove 708 is provided on the bottom surface of the mounting groove 2, with both ends of the drainage groove 708 penetrating the substation box 1. This allows cleaning fluid or rainwater to flow through the dustproof mesh 401 to the water passage hole 707, and then be discharged through the drainage groove 708.

[0038] The working principle of this utility model is as follows: When using the prefabricated box-type substation of this utility model, when installing the dustproof component 4, firstly, the dustproof mesh frame 402 is inserted into the mounting groove 2. Then, the support column 606 at the bottom of the mounting frame 501 is inserted into the slot 602. The mounting frame 501 is pressed down to compress the compression spring 603 until the top of the guide pipe 607 is lower than the bottom surface of the water storage tank 604. Then, the mounting frame 501 is pressed towards the side wall of the substation box 1 so that the mounting frame 501 contacts the dustproof mesh frame 402 and the side wall of the substation box 1. Then, the mounting frame 501 is released. Under the restoring force of the compression spring 603, the mounting frame 501 moves upward to insert the guide pipe 607 into the guide hole 605, thereby fixing the protective cover to the side wall of the substation box 1.

[0039] By pulling the handle 705, the movable plate 701 slides on the slide bar 702, causing the brush 703 to brush across the surface of the dustproof net 401, thereby removing the attached dust. Cleaning can be performed without disassembling the dustproof net 401, improving maintenance efficiency.

[0040] When cleaning the dustproof net 401 using the cleaning component 7, cleaning fluid or water is added to the water storage tank 604. The cleaning fluid is guided through the guide pipe 607 and the guide plate 706 to flow to the dustproof net 401, enhancing the cleaning effect of the dustproof net 401 in conjunction with the cleaning component 7. Simultaneously, in rainy weather, the water storage tank 604 can collect rainwater, which, through the guide pipe 607 and the guide plate 706, is guided to wash the dustproof net 401, achieving self-cleaning. After passing through the dustproof net 401, the cleaning fluid or rainwater flows to the water passage 707 and is discharged through the drain trough 708.

[0041] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
