Description

Technical Field

[0001] This utility model relates to the field of substation protection technology, and in particular to a high-voltage substation protection installation device. Background Technology

[0002] High-voltage substations are important infrastructure in power systems, mainly used to change voltage levels and achieve efficient transmission and distribution of electrical energy. Substation protection devices are typically used to isolate the workplace from energized areas or to spatially isolate hazardous areas to prevent workers from accidentally touching live equipment when they enter the wrong area.

[0003] Without proper protection and isolation, substations require a high-voltage substation protection installation device. For example, Chinese Patent Publication No. "CN215564947U" discloses a substation safety guardrail, comprising several adjacent guardrail units. A base pile is installed between adjacent guardrail units to fix them. The base pile has slots on both sides, into which a fixing rod from the side end of the guardrail unit is inserted. A vertical mounting hole is located in the center of the base pile, and a rotating adjusting rod is installed inside the mounting hole. Several sliding holes communicating with corresponding slots are opened on both sides of the adjusting rod. A movable block, adjustable by the adjusting rod, is installed in each sliding hole. An elastic piece is fixed to the outside of the movable block, directly opposite the fixing rod on the side end of the guardrail unit. This guardrail is easy to assemble and disassemble, saving time and effort. Furthermore, its stability is greatly enhanced after installation, improving the overall stability of the guardrail installation to prevent it from tipping over and ensuring the safety of substation construction.

[0004] In practice, adjacent guardrail units are connected to the foundation piles via a fixed structure. However, considering that the foundation piles can only fix the guardrail units on one side in one direction, it is not convenient to fix the guardrail units on the other side. This results in the need for additional connecting structures to fix the guardrail units when they are enclosed, which affects the installation efficiency and makes them less practical.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A high-voltage substation protection installation device includes a railing 1, a plurality of railings 1 are connected by connecting seats 2 and footings 3 to form a fence, a pair of connecting seats 2 are provided above the footings 3, the railings 1 are provided on the opposite sides of the pair of connecting seats 2 and between the bottom of the connecting seats 2 and the footings 3;

[0025] The pair of connecting seats 2 are rotatably folded together by a locking assembly 4. The locking assembly 4 includes a housing part 41 and an unlocking rod 42. An anti-accidental contact structure 5 is provided between the housing part 41 and the unlocking rod 42.

[0026] In some embodiments, the railing 1 and the connecting seat 2 are fixedly connected by locking bolts, and the railing 1 and the foot 3 are rotatably connected. At least one horizontally arranged railing 1 is also provided between the bottoms of two adjacent longitudinally arranged railings 1 to enhance the stability of the fence.

[0027] Specifically, driving the railing 1 to rotate enables the connecting seat 2 to rotate synchronously. After the angle of the multiple sets of connecting seats 2 is adjusted and fixed by the locking assembly 4, the multiple sets of railing 1 are enclosed to form a fence, and the substation equipment is placed inside the fence for protection.

[0028] Furthermore, the connecting seat 2 has a triangular structure, with the railing 1 fixedly connected to both protruding ends. A pair of connecting seats 2 are arranged opposite each other, and each of them has a clearance groove 21 on its top side. The outer shell part 41 is placed between the clearance grooves 21.

[0029] Furthermore, the locking assembly 4 also includes a connecting rod 43, which is fixedly connected to the relief groove 21. A first locking member 44 is fixedly connected to the top of a pair of connecting rods 43. The first locking member 44 has a gear-shaped structure.

[0030] The outer shell 41 covers the periphery of the first locking member 44, and the bottom of the outer shell 41 is also provided with an opening groove to avoid the first locking member 44.

[0031] More specifically, it also includes a second locking member 45, the top of which is fixedly connected to the unlocking rod, and the second locking member 45 is slidably connected between a pair of first locking members 44 via a slide rod 46 and a compression spring 47. The second locking member 45 is engaged with the teeth of a pair of first locking members 44 by a continuous limiting groove on both sides.

[0032] In this embodiment, as Figure 4 As shown, a pair of slide rods 46 are fixedly connected to the bottom of the inner part of the outer casing 41. The slide rods 46 are slidably connected to the second locking member 45, and a protrusion is threadedly connected to the top of the slide rods 46. The protrusion abuts against the second locking member 45 and is used to fix the second locking member 45.

[0033] Specifically, a compression spring 47 is sleeved around the slide bar 46. The two ends of the compression spring 47 abut against the inner bottom of the outer shell 41 and the top of the second locking member 45, respectively. The compression spring 47 is used to reset the second locking member 45 and to circumferentially lock the second locking member 45 by a pair of slide bars 46.

[0034] More specifically, the second locking member 45 engages with the teeth of the first locking members 44 on both sides through the limiting grooves on both sides, thereby adjusting the included angle between the pair of connecting seats 2. Furthermore, because the two adjacent connecting seats 2 are connected by a rectangular outer shell 41, the two adjacent connecting seats 2 can be folded and stored. After storage, the two connecting seats 2 and the outer shell 41 form a U-shaped structure, and the locking assembly 4 can also prevent the two connecting seats 2 from moving.

[0035] In general, the top of the pair of connecting rods 43 passes through the outer shell portion 41, and the top of the connecting rods 43 is provided with an elastic deformation portion 431, which fixes the outer shell portion 41.

[0036] In this embodiment, both the elastic deformation part 431 and the movable part 51 are preferably made of materials with deformation capabilities such as rubber and plastic. The elastic deformation part 431 has a protruding structure. The protruding part and the top of the connecting rod 43 are both formed by forming a deformation groove through the middle. The protruding part passes through the top of the outer shell part 41 through the deformation groove and is engaged with the outer shell part 41, so as to realize the function of fixing the outer shell part 41 and the pair of connecting rods 43.

[0037] Specifically, the connecting rod 43 is rotatably connected to the outer casing 41.

[0038] Finally, the anti-accidental touch structure 5 includes a movable part 51, which is rotatably connected to the top of the outer shell 41. The movable part 51 is an elastic structure with a C-shaped free end, and is engaged with the outer periphery of the end of the unlocking rod 42 by abutting deformation.

[0039] The end of the unlocking rod 42 passes through the outer shell 41 and is fixedly connected to a baffle 52, which abuts against the movable part 51.

[0040] In this embodiment, a pressing block is provided at the end of the unlocking rod 42 away from the second locking member 45. By pressing the unlocking rod 42 with the pressing block, the unlocking rod 42 is driven to drive the second locking member 45 to disengage from the first locking members 44 on both sides.

[0041] Specifically, the top of the unlocking rod 42 is divided into two parts by the baffle 52. Under normal circumstances, the unlocking rod 42 slides upward under the action of the compression spring 47. At this time, the movable part 51 is engaged with the bottom part of the unlocking rod 42 of the baffle 52, which can prevent the unlocking rod 42 from being accidentally pressed down.

[0042] When the unlocking lever 42 is pressed down, the movable part 51 can engage with the unlocking lever 42 on the top part of the baffle 52 to prevent the unlocking lever 42 from resetting and affecting the angle adjustment between the pair of connecting seats 2.

[0043] Working method: During operation, a horizontal railing 1 is fixedly connected to one end of the top of the connecting seat 2, and a vertical railing 1 is rotatably connected between the bottom end and the foot 3. Then, the angle between a pair of connecting seats 2 is adjusted by the locking assembly 4 so that multiple sets of railings 1 can be driven to form a fence by closing together to protect the substation equipment.

[0044] In specific operation, by pressing the unlocking rod 42 with the pressing block, the unlocking rod 42 drives the second locking member 45 to disengage from the first locking members 44 on both sides. At this time, the included angle between the two adjacent connecting seats 2 can be adjusted. Then, the unlocking rod 42 is reset under the action of the compression spring 47, and the second locking member 45 locks and fixes the first locking members 44 on both sides again to achieve the function of fixing the angle.

[0045] Finally, when the movable part 51 engages with the unlocking rod 42 at the bottom of the baffle 52, it can prevent the unlocking rod 42 from being accidentally pressed down; the movable part 51 can engage with the unlocking rod 42 at the top of the baffle 52 to prevent the unlocking rod 42 from resetting.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
