Description
Technical Field
[0001] The utility model relates to the technical field of transformer boxes, and particularly relates to a transformer box assembly for a substation. Background Art
[0002] A transformer box is a box for protecting power equipment that transforms, concentrates, and distributes the voltage and current of electric energy. The transformer box can ensure the quality of power equipment and the safety of electrical equipment, and at the same time prevent direct damage to power equipment by external personnel.
[0003] When the power distribution device inside the transformer box needs to be repaired due to a malfunction, the maintenance personnel need to open the box door and then bend down to reach into the box body for maintenance work. Therefore, due to the small space inside the box body and the inability to adjust the body, it is not convenient for the maintenance personnel to repair the malfunctioning power distribution device inside the transformer box. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a transformer box assembly for a substation to solve the problems raised in the above background art.

Specific implementation manners
[0025] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0026] The following further describes the present utility model in detail with reference to the embodiments:
[0027] As Figures 1-7 shown, the present utility model provides a substation box assembly for a substation, including a substation box housing 1. A movable reinforcement frame 5 is movably connected to the outer wall of the substation box housing 1, and a deflection closing door 4 for closing it is slidably connected to the inner wall of the substation box housing 1 near the front.
[0028] A reinforcement frame guide groove 3 is opened at the top of the substation box housing 1. A first directional wheel 11 adapted to the reinforcement frame guide groove 3 is fixedly connected to the top inner wall of the movable reinforcement frame 5. A second directional wheel 12 is fixedly connected to the bottom end of the first directional wheel 11. A receiving frame for receiving the second directional wheel 12 is fixedly connected to the outer wall of the substation box housing 1 near the bottom end. After the maintenance is completed, the deflection closing door 4 is reset for closing. Then, the push handle 9 is pulled to reset the movable reinforcement frame 5, and the positioning threaded rod 10 is rotated so that one end of the positioning threaded rod 10 is rotatably installed into the inner wall of the threaded hole 16 to complete the locking work of the movable reinforcement frame 5, and thus the closing of the substation box housing 1 can be completed.
[0029] A first ball socket 14 is fixedly connected to the bottom end near the left side of the deflection closing door 4, and a second ball socket 15 is fixedly connected to the bottom end near the right side of the deflection closing door 4. A closing door guiding groove 2 for receiving the first ball socket 14 is provided at the bottom of the inner wall of the substation box housing 1, and an inner guiding groove 6 for receiving the second ball socket 15 is provided at the bottom of the inner wall of the closing door guiding groove 2. An outer moving groove 7 is provided on the inner wall of the inner guiding groove 6. Similarly, a closing door guiding groove 2, an inner guiding groove 6 and an outer moving groove 7 are also provided at the top of the inner wall of the substation box housing 1.
[0030] The bottom end of the first ball socket 14 is slidably connected to the inner wall of the closing door guiding groove 2, and the bottom end of the second ball socket 15 is slidably connected to the inner wall of the inner guiding groove 6. The width of the outer moving groove 7 exactly reaches the distance required for the subsequent reset of the second ball socket 15, and at the same time, it does not cause the first ball socket 14 to disengage from it.
[0031] As Figures 1-7 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a support and reinforcement rod 8 is fixedly connected to the inner wall of the substation box housing 1. A threaded hole 16 is provided in the support and reinforcement rod 8 for the first time, and a positioning threaded rod 10 is threadedly connected to the inner wall of the threaded hole 16. One end of the positioning threaded rod 10 away from the support and reinforcement rod 8 movably penetrates to one side of the moving reinforcement frame 5.
[0032] A closing strip 13 is fixedly connected to one side of the moving reinforcement frame 5, and a push handle 9 is fixedly connected to the other side of the moving reinforcement frame 5. The closing strip 13 can be made of rubber material. Thus, after the moving reinforcement frame 5 is reset to form a closure for the substation box housing 1, the sealing performance of the substation box housing 1 can be ensured through the closing strip 13.
[0033] The bottom end of the first directional wheel 11 is movably connected to the inner wall of the reinforcement frame guiding groove 3.
[0034] The number of the moving reinforcement frames 5 is two groups, and the two groups of moving reinforcement frames 5 are symmetrically distributed on both sides of the substation box housing 1.
[0035] Next, the working principle of the substation box assembly for the substation will be specifically described.
[0036] As Figures 1-7 shown, when it is necessary to repair the components inside the substation box housing 1, first open the deflection closing door 4 and then pull it towards the side of the substation box housing 1. At this time, the first ball socket 14 at the bottom end of the deflection closing door 4 rolls on the inner wall of the closing door guiding groove 2, while the bottom end of the second ball socket 15 rolls on the inner wall of the inner guiding groove 6. As the deflection closing door 4 moves, the second ball socket 15 is moved out from the inner wall of the outer moving groove 7, so that it disengages from the inner wall of the inner guiding groove 6.
[0037] Afterwards, when the first ball seat 14 abuts against the inlet of the outer shifting groove 7, the deflecting closing door 4 is pushed towards the back of the power transformation box housing 1. At this time, the first ball seat 14 continues to move along the inner wall of the closing door guiding groove 2, so that the deflecting closing door 4 approaches a position parallel to the side of the power transformation box housing 1. When the second ball seat 15 abuts against the port of the outer shifting groove 7, the second ball seat 15 is reset into the built-in guiding groove 6. Then, the deflecting closing door 4 is pushed backward so that it is placed within the space formed by the side of the power transformation box housing 1 and the moving reinforcing frame 5. At the same time, the front surface of the deflecting closing door 4 fits against the side of the power transformation box housing 1.
[0038] It should be noted that in this text, the term "including", "comprising" or any other variant is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or still includes elements inherent in such a process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the said element. The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
