Description

Technical Field

[0001] This utility model relates to the field of power distribution switch simulation test technology, and in particular to a power distribution switch simulation test box. Background Technology

[0002] A power distribution switch simulation test box is a device specifically designed to test and simulate the operation of various switches in a power distribution system. It is mainly used in the installation, commissioning, maintenance and troubleshooting of power systems to help technicians more accurately judge the working status of power distribution switches and their impact on the entire circuit system.

[0003] In the prior art (Chinese invention patent application CN215267256U, entitled "An Electrical Switch Distribution Box for Easy Maintenance"), by setting up a support plate, a rotating shaft, a bearing, and a connecting plate, when people need to maintain electrical components, they release the restriction on the box door, then push the box door downwards so that the box door contacts the connecting plate, and push the connecting plate backwards, causing the connecting plate to rotate around the rotating shaft. This pushes the support plate, which is fixed to the fixing plate, outwards from the box. When the fixing plate is pushed out of the box, the box door is restricted, allowing for easy maintenance of the electrical components inside the distribution box. In implementing this technical solution, the inventors discovered at least the following problems in the prior art:

[0004] Because test kits are typically placed on the ground or workbench for operation, their design often lacks sufficient stability. When workers accidentally kick the device in a busy or crowded work environment, it can easily cause the equipment to move, resulting in broken or loose connections. In actual work scenarios, especially during field operations, the connections are easily damaged when the equipment is moved or impacted, further affecting the equipment's performance and lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a power distribution switch simulation test box, which can prevent the equipment from moving when the staff accidentally touches the equipment in a busy or crowded work environment, thereby causing the connection wires to be interrupted or loosened.

[0007] Preferably, a fixed pressing plate is fixedly connected to the side wall of the power distribution switch box, a hydraulic tank is slidably connected to the side wall of the fixed pressing plate, a return spring is fixedly connected to the side wall of the fixed pressing plate, a buffer pressing plate is fixedly connected to the end of the return spring away from the hydraulic tank, and the side wall of the buffer pressing plate is slidably connected to the inner wall of the hydraulic tank.

[0008] Preferably, a hinge seat is fixedly connected to the outer surface of the fixed extrusion plate, a push rod is rotatably connected to the side wall of the hinge seat, and a connecting shaft is rotatably connected to the end of the push rod away from the hinge seat.

[0009] Preferably, a translation block is rotatably connected to the outer wall of the connecting shaft, a limiting groove plate is slidably connected to the outer wall of the translation block, and the side wall of the limiting groove plate is fixedly connected to the side wall of the hydraulic tank.

[0010] Preferably, a guide rail is fixedly connected to the inner side of the buffer compression plate, an inclined plate is slidably connected to the side wall of the guide rail, an inclined guide groove is provided on the side wall of the inclined plate, an L-shaped guide rod is slidably connected to the inner wall of the inclined guide groove, and the end of the L-shaped guide rod away from the inclined plate is fixedly connected to the outer surface of the translation block.

[0011] Preferably, a drain pipe is connected to the bottom of the hydraulic tank, and a hydraulic cylinder is fixedly connected to the end of the drain pipe away from the hydraulic tank. A hydraulic push rod is slidably connected to the inner wall of the hydraulic cylinder, and the hydraulic push rod passes through the inner wall of the hydraulic cylinder and extends to the outer side.

[0012] Preferably, an L-shaped bracket is fixedly connected to the left end of the hydraulic cylinder, the side wall of the L-shaped bracket is fixedly connected to the side wall of the power distribution switch box, and a push plate is fixedly connected to the right end of the hydraulic push rod.

[0013] Preferably, a connecting spring is fixedly connected to the right side of the push plate, and a clamping frame is fixedly connected to the end of the connecting spring away from the push plate. The bottom of the clamping frame is fixedly connected to the top of the power distribution switch box.

[0014] Preferably, a sliding rod is fixedly connected to the inner wall of the clamping frame, a movable plate is slidably connected to the outer wall of the sliding rod, and a guide sliding rod is fixedly connected to the side wall of the movable plate.

[0015] Preferably, a V-shaped groove plate is slidably connected to the outer wall of the guide slide rod, the side wall of the V-shaped groove plate is fixedly connected to the right side of the push plate, and an annular clamping plate is fixedly connected to the outer surface of the moving plate.

[0016] The beneficial effects of this application are:

[0017] 1. In this power distribution switch simulation test box, when a worker accidentally kicks the device in a busy or crowded work environment, the buffer squeeze plate moves into the hydraulic tank. The hydraulic oil and return spring inside the hydraulic tank have good energy absorption characteristics, which can effectively disperse and reduce the impact force on the internal structure of the equipment, reduce the impact force, and improve stability.

[0018] 2. In this power distribution switch simulation test box, when the buffer compression plate moves, the hinge seat pushes the push rod to move. The push rod pushes the translation block through the connecting shaft, causing it to slide within the limiting groove plate. The translation block drives the L-shaped guide rod to move. Because the L-shaped guide rod slides within the inclined guide groove, the inclined plate can be lowered through the inclined guide groove as the L-shaped guide rod moves. As the L-shaped guide rod moves, the inclined plate gradually descends and contacts the ground. After the inclined plate contacts the ground, it raises one side of the equipment to adjust its posture and, by locking it to the ground, prevents the equipment from moving further. Since the equipment no longer moves, the connection between the aviation connector and the connecting cable is more stable, reducing the risk of cable breakage due to equipment movement, avoiding cable interruption or loosening, and increasing the service life of the equipment.

[0019] 3. In this power distribution switch simulation test box, when the hydraulic oil in the hydraulic tank is squeezed, the hydraulic oil enters the hydraulic cylinder through the drain pipe. The hydraulic oil pushes the hydraulic push rod to move outward, which in turn pushes the push plate. The push plate drives the V-shaped groove plate to move. Because the V-shaped groove plate guides the guide slide rod, the guide slide rod slides along the inclined surface of the V-shaped groove plate. The guide slide rod drives the moving plate and the annular clamping plate to move. As the annular clamping plate moves, it clamps and fixes the connecting wire, ensuring that the connecting wire will not loosen or fall off due to the movement of the equipment, thus improving the continuity and accuracy of the test process.

[0033] A fixed pressing plate 201 is fixedly connected to the side wall of the power distribution switch box 101. A hydraulic tank 202 is slidably connected to the side wall of the fixed pressing plate 201. A return spring 203 is fixedly connected to the side wall of the fixed pressing plate 201. A buffer pressing plate 204 is fixedly connected to the end of the return spring 203 away from the hydraulic tank 202. The side wall of the buffer pressing plate 204 is slidably connected to the inner wall of the hydraulic tank 202. This arrangement is designed so that when a worker accidentally kicks the device in a busy or crowded work environment, the buffer pressing plate 204 moves into the hydraulic tank 202. The hydraulic oil inside the hydraulic tank 202 and the return spring 203 have good energy absorption characteristics, which can effectively disperse and reduce the impact force on the internal structure of the equipment, reduce the impact force, and improve stability.

[0034] A hinge seat 301 is fixedly connected to the outer surface of the fixed extrusion plate 201. A push rod 302 is rotatably connected to the side wall of the hinge seat 301.

The side wall of the limit groove plate 305 is fixedly connected to the side wall of the hydraulic tank 202. This arrangement is for the hinge seat 301 to push the push rod 302 to move, and the push rod 302 pushes the translation block 304 through the connecting shaft 303, so that it slides within the limit groove plate 305.

[0035] A guide rail 401 is fixedly connected to the inner side of the buffer compression plate 204. An inclined plate 402 is slidably connected to the side wall of the guide rail 401. This is designed so that the inclined plate 402 can slide on the guide rail 401. An inclined guide groove 403 is provided on the side wall of the inclined plate 402. An L-shaped guide rod 404 is slidably connected to the inner wall of the inclined guide groove 403. The end of the L-shaped guide rod 404 away from the inclined plate 402 is fixedly connected to the outer surface of the translation block 304. This is designed so that when the L-shaped guide rod 404 moves, the inclined plate 402 can be lowered through the inclined guide groove 403.

[0036] A drain pipe 501 is connected to the bottom of the hydraulic tank 202. A hydraulic cylinder 502 is fixedly connected to the end of the drain pipe 501 away from the hydraulic tank 202. A hydraulic push rod 504 is slidably connected to the inner wall of the hydraulic cylinder 502. The hydraulic push rod 504 passes through the inner wall of the hydraulic cylinder 502 and extends to the outside. This is so that hydraulic oil enters the hydraulic cylinder 502 through the drain pipe 501 and pushes the hydraulic push rod 504 to move outward.

[0037] An L-shaped bracket 503 is fixedly connected to the left end of the hydraulic cylinder 502. The side wall of the L-shaped bracket 503 is fixedly connected to the side wall of the power distribution switch box 101. A push plate 505 is fixedly connected to the right end of the hydraulic push rod 504. A connecting spring 506 is fixedly connected to the right side of the push plate 505.

[0038] A slide rod 51 is fixedly connected to the inner wall of the clamping frame 507. A moving plate 52 is slidably connected to the outer wall of the slide rod 51. A guide slide rod 53 is fixedly connected to the side wall of the moving plate 52. A V-shaped groove plate 54 is slidably connected to the outer wall of the guide slide rod 53. This arrangement is for the V-shaped groove plate 54 to guide the guide slide rod 53. The guide slide rod 53 slides along the inclined surface of the V-shaped groove plate 54. The side wall of the V-shaped groove plate 54 is fixedly connected to the right side of the push plate 505. An annular clamping plate 55 is fixedly connected to the outer surface of the moving plate 52. This arrangement is for the annular clamping plate 55 to clamp and fix the connecting wire, ensuring that the connecting wire will not loosen or fall off due to equipment movement.

[0039] In summary, the working principle of a power distribution switch simulation test box according to this utility model embodiment is as follows: when a worker accidentally kicks the device in a busy or crowded work environment, the buffer compression plate 204 moves into the hydraulic tank 202. The hydraulic oil and return spring 203 inside the hydraulic tank 202 have good energy absorption characteristics, which can effectively disperse and reduce the impact of the impact force on the internal structure of the equipment, reduce the impact force, and improve stability.

[0040] As the buffer compression plate 204 moves, the hinge seat 301 pushes the push rod 302 to move. The push rod 302 pushes the translation block 304 through the connecting shaft 303, causing it to slide within the limiting groove plate 305. The translation block 304 drives the L-shaped guide rod 404 to move. Because the L-shaped guide rod 404 slides within the inclined guide groove 403, the inclined plate 402 can be lowered through the inclined guide groove 403 as the L-shaped guide rod 404 moves. As the L-shaped guide rod 404 moves, the inclined plate 402 gradually descends and contacts the ground. After the inclined plate 402 contacts the ground, it raises one side of the equipment to adjust its posture and prevents the equipment from moving further by locking it to the ground. Since the equipment no longer moves, the connection between the aviation connector 102 and the connecting line is more stable, reducing the risk of the connecting line being cut due to equipment movement, avoiding connection line interruption or loosening, and increasing the service life of the equipment.

[0041] When the hydraulic oil in the hydraulic tank 202 is squeezed, the hydraulic oil enters the hydraulic cylinder 502 through the drain pipe 501. The hydraulic oil pushes the hydraulic push rod 504 to move outward, which in turn pushes the push plate 505. The push plate 505 drives the V-shaped groove plate 54 to move. Because the V-shaped groove plate 54 guides the guide slide rod 53, the guide slide rod 53 slides along the inclined surface of the V-shaped groove plate 54. The guide slide rod 53 drives the moving plate 52 and the annular clamping plate 55 to move. As the annular clamping plate 55 moves, it clamps and fixes the connecting wire, ensuring that the connecting wire will not loosen or fall off due to the movement of the equipment, thus improving the continuity and accuracy of the testing process.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
