Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated substations, specifically a prefabricated substation that is easy to maintain. Background Technology

[0002] A prefabricated box-type substation is a compact, factory-prefabricated indoor / outdoor power distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices 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, representing a new type of substation that has emerged after traditional civil engineering substations. Box-type 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] A search revealed Chinese patent application number 202011302789.8, which discloses a prefabricated substation, comprising a base, enclosure walls, an installation and fixing mechanism, and an enclosure cover adjustment mechanism. The base is fixedly installed in a concrete-poured foundation pit. Enclosure walls are installed around the perimeter of the upper surface of the base. The installation and fixing mechanism is located on the exterior of the enclosure walls, and the enclosure cover adjustment mechanism is installed on the upper surface of the enclosure walls. This patent can solve the following problems existing in the installation and use of prefabricated substations: a. Currently, most existing prefabricated substations are installed outdoors on-site, which requires convenient assembly and adjustment, as well as convenient maintenance during operation. Moreover, since current prefabricated substations are installed on-site, for locations with good outdoor geographical conditions, the substation can be pre-assembled and then transported to the site for direct installation and use, reducing the installation cycle and outdoor commissioning, and improving work efficiency; b. Because prefabricated substations need to be suitable for various environments, they can maintain good operating conditions when facing various harsh environments.

[0004] While the aforementioned patent allows for the pre-assembly of substations in well-located outdoor locations, enabling them to be transported to the site for direct installation and use, thus reducing installation time and outdoor commissioning, improving work efficiency, and maintaining good operating conditions, in actual use, when a substation malfunctions, it is inconvenient for maintenance personnel to open the substation for internal inspection and maintenance, and it is also inconvenient for staff to conduct regular inspections of the electrical equipment inside the substation, increasing the workload of the staff.

[0005] Therefore, it is necessary to modify the substation so that staff can easily and quickly open it for inspection and maintenance, and conveniently shut it down after maintenance, thereby improving the protection of the electrical facilities inside the substation. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a prefabricated substation that is easy to maintain. This substation allows staff to easily and quickly open it for inspection and maintenance, and facilitates its shutdown after maintenance. It also improves the protection of the internal electrical facilities and is convenient for users. This solution addresses the problems of maintenance personnel finding it inconvenient to open the substation for internal inspection and maintenance, as well as the inconvenience of regular inspections of the internal electrical equipment, which increases the workload of staff and is inconvenient for users.

[0007] This utility model provides the following technical solution: a prefabricated substation that is easy to maintain, including a base plate. A housing is fixedly connected to the top of the base plate, and electrical equipment located inside the housing is fixedly connected to the top of the base plate. Tracks are fixedly connected to the top and bottom of the front of the housing, and a first sliding door, a second sliding door, and a third sliding door are slidably connected sequentially from left to right on opposite sides of the two track rails. Square grooves are formed at the top and bottom of the first, second, and third sliding doors, and rollers are rotatably connected to the left and right sides inside the square grooves. The surfaces of the rollers are flush with the inner walls of the track rails. The system features a rolling connection. A foot pedal is located on the front side of the top of the base plate. A through-hole is formed on both the left and right sides of the foot pedal, and a support column is slidably connected inside the hole. The top of the support column is fixedly connected to the bottom of the track bar, and the bottom of the support column is fixedly connected to the top of the base plate. A compression spring is fitted onto the surface of the support column, with its top fixedly connected to the bottom of the foot pedal and its bottom fixedly connected to the top of the base plate. Several evenly distributed locking rods are fixedly connected to the top of the foot pedal, with their bottom ends penetrating into the track bar and fitting against the surface of the roller.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model protects electrical equipment by setting a base plate and a shell, placing the electrical equipment inside the shell. When maintenance is required, the foot pedal can be pressed down to move it downwards. This downward movement of the foot pedal moves the locking lever downwards, moving it away from the track bar and releasing the limiting fixation of the rollers at the bottom of the first, second, and third sliding doors. This allows the first, second, and third sliding doors to slide inside the track bar. At this time, the first sliding door can be pushed to the right or the third sliding door to the left, causing the sliding doors to overlap and open the substation, facilitating maintenance by personnel. When the substation needs to be closed, the sliding doors are reset, and the foot pedal is released. As the foot pedal slides on the surface of the support column, it moves upwards under the pressure of the compression spring, causing the locking lever to reset and enter the track bar, fixing the rollers. This secures the sliding doors, allowing personnel to easily and quickly open the substation for maintenance and conveniently close it after maintenance, thus improving the protection of the electrical facilities inside the substation.

[0010] 2. By using T-shaped blocks and T-shaped grooves in combination, this utility model strengthens the connection between the contact surfaces of the first and second sliding doors and the second and third sliding doors, ensuring that each sliding door remains perpendicular and preventing tilting that could affect normal movement, thus further improving the stability of the device.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1 to 6As shown, the prefabricated substation of this embodiment includes a base plate 1, a housing 2 fixedly connected to the top of the base plate 1, and electrical equipment 3 located inside the housing 2 fixedly connected to the top of the base plate 1. Tracks 4 are fixedly connected to the top and bottom of the front of the housing 2, and a first sliding door 5, a second sliding door 6, and a third sliding door 7 are slidably connected sequentially from left to right on opposite sides of the two track bars 4. Square grooves 8 are provided at the top and bottom of the first sliding door 5, the second sliding door 6, and the third sliding door 7. Rollers 9 are rotatably connected to the left and right sides inside the square grooves 8, and the surfaces of the rollers 9 are in rolling contact with the inner walls of the track bars 4. A foot pedal 10 is provided on the front side. A through circular hole is provided on both the left and right sides of the foot pedal 10. A support column 11 is slidably connected inside the circular hole. The top of the support column 11 is fixedly connected to the bottom of the track bar 4. The bottom of the support column 11 is fixedly connected to the top of the base plate 1. A compression spring 12 is sleeved on the surface of the support column 11. The top of the compression spring 12 is fixedly connected to the bottom of the foot pedal 10. The bottom of the compression spring 12 is fixedly connected to the top of the base plate 1. A number of evenly distributed locking rods 13 are fixedly connected to the top of the foot pedal 10. The bottom of the locking rods 13 penetrates into the interior of the track bar 4 and fits against the surface of the roller 9.

[0019] refer to Figure 2 The front of the first sliding door 5 is slidably connected to the back of the second sliding door 6, and the front of the second sliding door 6 is slidably connected to the back of the third sliding door 7. T-shaped blocks 14 are fixedly connected to the right side above the front of the first sliding door 5 and the right side above the front of the second sliding door 6. T-shaped grooves 15 that cooperate with the T-shaped blocks 14 are provided on the left side of the back of the second sliding door 6 and the left side of the back of the third sliding door 7. The T-shaped blocks 14 and the T-shaped grooves 15 are slidably connected.

[0020] In this embodiment, the use of T-shaped blocks 14 and T-shaped grooves 15 reinforces the contact surfaces between the first sliding door 5 and the second sliding door 6, and between the second sliding door 6 and the third sliding door 7, ensuring that the sliding doors remain perpendicular and preventing them from tilting and affecting normal movement, thus further improving the stability of the device.

[0021] refer to Figure 1 A sealing plate 16 is fixedly connected to the front of the track bar 4. The back of the sealing plate 16 is in contact with the front of the third sliding door 7. Rubber pads 17 are fixedly connected to the front of both sides of the inner wall of the outer shell 2. The inner sides of the two rubber pads 17 are in contact with the left side of the first sliding door 5 and the right side of the third sliding door 7, respectively. A sealing plate 18 located behind the foot pedal 10 is fixedly connected to the top of the bottom plate 1. The top of the sealing plate 18 is fixedly connected to the bottom of the track bar 4.

[0022] In this embodiment, the sealing plate 16 seals the top and bottom of the first sliding door 5, the second sliding door 6, and the third sliding door 7, preventing dust and impurities from entering the housing 2 through the gaps at the top and bottom of each sliding door and affecting the operation of the electrical equipment 3. The rubber pad 17 reduces the impact force when the sliding doors collide with the housing 2 during movement, preventing damage to the sliding doors from collisions. The sealing plate 18 seals the gaps at the top front of the base plate 1, further improving the overall sealing performance of the substation.

[0023] refer to Figure 1 and Figure 4 The outer shell 2 has several evenly distributed ventilation slots 19 on both the left and right sides. The outer shell 2 has protective covers 20 fixedly connected to the outside of the ventilation slots 19 on both the left and right sides. The protective covers 20 have air inlet slots on their surface and filters are fixedly connected inside the air inlet slots.

[0024] This embodiment improves the overall ventilation effect of the substation and accelerates internal heat dissipation by setting up ventilation slots 19. The protective cover 20 protects the ventilation slots 19 and prevents dust and foreign objects from entering the casing 2 through the ventilation slots 19 and causing damage to the electrical equipment 3 without affecting the ventilation effect.

[0025] refer to Figure 1 and Figure 4 A ventilation groove 21 is provided in the center of the base plate 1. A wire mesh is fixedly connected inside the ventilation groove 21. A lifting frame 22 is fixedly connected to the bottom of the base plate 1. A number of evenly distributed ventilation holes 23 are provided on both the front and rear sides of the lifting frame 22. An insulating pad 24 is fixedly connected to the bottom of the lifting frame 22.

[0026] In this embodiment, by setting up the ventilation groove 21, external air can enter the substation from the bottom, which accelerates the air flow inside the substation and further improves the heat dissipation effect. By setting up the riser 22 and ventilation holes 23, the ground clearance of the substation is increased, which accelerates heat dissipation. By setting up the insulating pad 24, the bottom of the substation is insulated and protected, which prevents the ground from becoming conductive and causing safety accidents when the substation malfunctions.

[0027] refer to Figure 1 An observation groove 25 is provided above the surface of the second sliding door 6. A transparent glass 26 is provided inside the observation groove 25. Sealing strips 27 are fixedly connected to all four sides of the transparent glass 26. The surface of the sealing strips 27 is fixedly connected to the inner wall of the observation groove 25.

[0028] In this embodiment, by using the observation slot 25 and the transparent glass 26 together, the internal equipment of the substation can be directly viewed through the observation slot 25 to facilitate the observation of its operating status. By setting the sealing strip 27, the sealing performance of the substation is further improved.

[0029] This utility model protects the electrical equipment 3 by setting a base plate 1 and a housing 2, with the electrical equipment 3 housed inside the housing 2. When maintenance is required, the foot pedal 10 can be pressed down to move it downwards. This downward movement of the foot pedal 10 causes the locking lever 13 to move downwards, moving it away from the track 4. This releases the limiting and fixing of the rollers 9 at the bottom of the first sliding door 5, the second sliding door 6, and the third sliding door 7, allowing them to slide inside the track 4. At this time, the first sliding door 5 can be pushed to the right or the third sliding door 7 can be pushed to the left. This allows the sliding doors to overlap, opening the substation and facilitating maintenance and repair of its internal equipment. When the substation needs to be closed, the sliding doors are reset, and the foot pedal 10 is released. As the foot pedal 10 slides on the surface of the support column 11, it moves upward under the pressure of the compression spring 12, causing the locking rod 13 to reset and enter the track bar 4, fixing the roller 9. This secures the sliding doors, allowing staff to easily and quickly open the substation for maintenance and repair, and conveniently close the substation after maintenance, thus improving the protection of the electrical facilities inside the substation.
