Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to a disconnecting switch. Background Technology

[0002] Disconnect switches, as the name suggests, are used in outdoor high-voltage power systems to switch circuits on and off when there is voltage but no load. They are indispensable for power plants, substations, and large industrial and mining enterprises. They are essential for high-voltage line switching and electrical equipment maintenance and isolation.

[0003] For example, a 35kV disconnector switch, with publication number CN222214039U, involves pushing a sliding plate to compress a spring and a telescopic rod, then placing the disconnector switch body above a support plate. A fixing plate is fitted onto the outside of a fixing box. Releasing the two sets of sliding plates causes the spring tension to push the sliding plates, moving the fixing block to the outside of the fixing plate. The fixing box limits the position of the disconnector switch body, and the spring tension fixes the fixing block, thus securing the disconnector switch body to the outside of the support plate. The fixing structure is located inside the fixing box, protecting it from rainwater and bird droppings, and extending the service life of the fixing mechanism.

[0004] However, as can be seen from the attached drawings of the existing technology, there are two fixed structures on both sides of the disconnector switch body. Therefore, in actual operation, two people are required to be on both sides of the support plate and move the two fixed structures on both sides of the disconnector switch body. It is redundant for two people to operate such a simple operation as moving the fixed structures, resulting in a waste of human resources. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing an isolating switch.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a disconnecting switch, including a disconnecting switch body and a base. Side baffles are inserted into the upper surface of the base at both sides of the disconnecting switch body. Each of the two side baffles has a sliding groove on its facing side. Two symmetrically arranged clamping blocks are disposed within the sliding grooves. One side of each clamping block extends upward through the groove opening and is slidably installed on the upper surface of the side baffle. The two clamping blocks within the same side baffle are symmetrically arranged and used to engage with the side of the disconnecting switch body. A sliding strip is detachably installed on the side of each clamping block located on the side of the side baffle. The sliding strip and the side of the side baffle... The two sliding strips on the same side of the stop bar are connected by elastic ropes on opposite sides. A connecting rod is fixedly installed at the bottom edge of the sliding strip near the elastic rope. Two symmetrically arranged inclined frames are inserted into the middle of the bottom edge of the side stop bar. The two inclined frames are located between the two connecting rods, and the inclined sides of the two inclined frames are slidably connected to the surfaces of the two connecting rods respectively. A traction head is inserted into one side of the bottom of the base. Two traction lines are provided on the traction head. One end of one traction line passes through the middle of the base and folds back to connect with the inclined frame near the traction head. The other end of the traction line is connected to the inclined frame away from the traction head.

[0007] Preferably, the upper surface of the base is hollowed out, and the two ends of the bottom edge of the side strip are inserted into the hollowed-out area on the upper surface of the base, and the opposite sides of the two side strips abut against the side of the disconnect switch body.

[0008] Preferably, sliders are slidably installed in the groove on the opposing sides of the two clamping blocks, and an internal spring rod is provided between each slider and the adjacent clamping block. The telescopic ends of the two internal spring rods in the same groove are arranged opposite each other.

[0009] Preferably, a bidirectional lead screw is rotatably connected in the slide groove, and both ends of the bidirectional lead screw are threaded through two sliders in the same slide groove. One end of the bidirectional lead screw extends outward through a side stop bar and is fitted with a handwheel.

[0010] Preferably, the side edge of the side guard strip and the surface of the sliding strip are both hollowed out, and bolts are installed between the hollowed-out part of the side guard strip and the clamping block, as well as between the hollowed-out part of the sliding strip and the clamping block.

[0011] Preferably, the two inclined frames on the same side of the baffle extend inwards towards each other and are fixedly connected, and the connection point of the two inclined frames on the same side of the baffle is inserted into the surface of the base.

[0012] Preferably, an outer spring rod is connected between the inclined frame and the bottom edge of the side guard strip.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a traction head, the inclined frames on both sides of the base can be moved relative to each other under the traction of two traction lines. By using the sliding connection between the inclined side of the connecting frame and the connecting rod, the two connecting rods on the two side rails can be moved away from each other. By using the fixed connection between the connecting rod and the sliding strip and the connection between the sliding strip and the clamping block, the two clamping blocks on the side rails can be moved away from each other as the two connecting plates move away from each other. That is, this solution can achieve the simultaneous movement of the two clamping blocks on both sides away from each other by a single person pulling the traction head, saving manpower.

[0015] 2. In this utility model, the distance between the two side bars is adjusted by inserting them into the hollowed-out parts at different positions on the base, ensuring that when the disconnect switch body is installed, its two sides are in close contact with the opposite sides of the two side bars, and the position of disconnect switch bodies of different sizes can be fixed in one direction.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-6 As shown, a disconnecting switch includes a disconnecting switch body 2 and a base 1. Side retaining strips 3 are inserted into the upper surface of the base 1 on both sides of the disconnecting switch body 2. The upper surface of the base 1 is hollowed out, and the bottom ends of the side retaining strips 3 are inserted into the hollowed-out areas on the upper surface of the base 1. The opposite sides of the two side retaining strips 3 abut against the sides of the disconnecting switch body 2. Figure 3 It can be seen that the part of the side retainer 3 that passes through the cutout of the base 1 can be fitted with a threaded nut. The nut is used to fix the side retainer 3 to the base 1. In actual use, the distance between the two side retainers 3 can be adjusted by inserting them into the cutouts at different positions on the base 1, according to the length of the disconnector switch body 2 to be installed. This ensures that when the disconnector switch body 2 is installed, its two sides are in close contact with the opposite sides of the two side retainers 3.

[0026] Both side retaining bars 3 have grooves 14 on their opposing sides. Two symmetrically arranged clamping blocks 4 are installed within the grooves 14. One side of each clamping block 4 extends upward through the groove opening and slides onto the upper surface of the side retaining bar 3. The two clamping blocks 4 within the same side retaining bar 3 are symmetrically arranged and used to engage with the side of the disconnector switch body 2. Slider blocks 16 are slidably installed within the grooves 14 on the opposing sides of the two clamping blocks 4. An internal spring rod 11 is provided between each slider 16 and the adjacent clamping block 4. The telescopic ends of the two internal spring rods 11 within the same groove 14 are positioned opposite each other. A bidirectional lead screw 10 is rotatably connected within the groove 14. Both ends of the bidirectional lead screw 10 are threaded through the two sliders 16 within the same groove 14. One end of the bidirectional lead screw 10 passes through the side retaining bar 3. A handwheel extends outward and is installed. Rotating the handwheel rotates the bidirectional lead screw 10, thereby causing the two sliders 16, which are threadedly connected to the bidirectional lead screw 10 within the slide groove 14, to move relative to or towards each other to adjust the distance. This, in turn, is driven by the internal spring rod 11, causing the two clamping blocks 4 to move synchronously to adjust the distance between them. This allows for adjustment based on the width of the placed disconnector switch body 2. When clamping the disconnector switch body 2, moving the two clamping blocks 4 away from each other overcomes the pushing force of the corresponding internal spring rod 11, facilitating the placement of the disconnector switch body 2 between the two clamping blocks 4. Then, the elastic extension and reset of the internal spring rod 11 allows the two clamping blocks 4 on the same side of the stop bar 3 to move relative to each other and lock onto the surface of the disconnector switch body 2.

[0027] The clamping block 4 is detachably mounted with a sliding strip 6 on the side of the side stop strip 3. The sliding strip 6 is inserted into the side of the side stop strip 3. Two sliding strips 6 on the same side stop strip 3 are connected to opposite sides by a tension rope 15. The tension of the tension rope 15 ensures that the two sliding strips 6 in the initial state are close to the middle of the side stop strip 3. A connecting rod 9 is fixedly installed at the bottom edge of the sliding strip 6 near the end of the tension rope 15. Two symmetrically arranged inclined frames 5 are inserted into the middle of the bottom edge of the side stop strip 3. The two inclined frames 5 are located between the two connecting rods 9, and the opposite inclined edges of the two inclined frames 5 are slidably connected to the surfaces of the two connecting rods 9 respectively. The connection point of the two inclined frames 5 on the same side stop strip 3 is inserted into the surface of the base 1. An outer spring rod 13 is connected between the inclined frame 5 and the bottom edge of the side stop strip 3. Under the connection action of the outer spring rod 13, the inclined frame 5 and the side stop strip 3 on the same side move synchronously. In actual use, Figure 2 For example, when the two inclined frames 5 on the left side of the base 1 move to the right, the connecting rods 9 that are attached to the inclined sides of the inclined frames 5 will gradually move away from the middle position of the side rail 3 as the inclined frames 5 move to the right. This means that the two connecting rods 9 on the side rail 3 move away from each other, and thus the two sliding strips 6 pull the elastic rope 15 to stretch and move away from each other. By connecting the sliding strips 6 with the clamping blocks 4, the two clamping blocks 4 inside the side rail 3 can be moved away from each other. Similarly, when the two inclined frames 5 on the right side of the base 1 move to the left, the two clamping blocks 4 on the corresponding right side rail 3 of the base 1 will move away from each other.

[0028] A traction head 8 is inserted into one side of the bottom of the base 1. Two traction lines 7 are provided on the traction head 8. One end of one traction line 7 passes through the middle of the base 1 and folds back to connect with the inclined frame 5 near the traction head 8. The other traction line 7 connects to the inclined frame 5 away from the traction head 8. Two inclined frames 5 on the same side of the baffle 3 extend inwards facing each other and are fixedly connected. Figure 3 When the traction head 8 is pulled to the left, the two inclined frames 5 on the left side of the base 1 can be moved to the right and the two inclined frames 5 on the right side can be moved to the left under the traction of the two traction lines 7, so that the two clamping blocks 4 of the two side bars 3 can move away from each other at the same time.

[0029] Additionally: The sides of the side guard strip 3 and the surface of the sliding strip 6 are both hollowed out. Bolts 12 are installed between the hollowed-out parts of the side guard strip 3 and the clamping block 4, and between the hollowed-out parts of the sliding strip 6 and the clamping block 4. When the bolts 12 are removed, the clamping block 4 can move relative to the side guard strip 3 and the sliding strip 6 when adjusting the initial position. During the movement, the internal spring rod 11 connected to the clamping block 4 will not elastically contract, and the sliding strip 6 will not move. After the clamping block 4 moves to the designated position, the corresponding hollowed-out parts on the sliding strip 6 are connected by the bolts 12 to achieve a rigid connection between the clamping block 4 and the sliding strip 6. Then, the corresponding hollowed-out parts on the side guard strip 3 are connected by the bolts 12 to fix the relative position of the clamping block 4 and the side guard strip 3. Therefore, the opposite sides of the two side guard strips 3 are used to prevent the disconnector switch body 2 from sliding left and right, and the two clamping blocks 4 fixed in relative position with the side guard strips 3 are used to fix the front and rear position of the disconnector switch body 2.

[0030] Working principle: The positions of the two side rails 3 on the base 1 are adjusted according to the length of the disconnector switch body 2. Based on the width of the disconnector switch body 2, the bidirectional screw 10 is rotated by turning the handwheel, causing the two sliders 16 threaded to the bidirectional screw 10 within the slide groove 14 to move relative to or towards each other, adjusting the distance. This, in turn, is driven by the internal spring rod 11, causing the two clamping blocks 4 to move synchronously, adjusting the distance between them. When installing the disconnector switch body 2, pulling the traction head 8 causes the inclined frames 5 on both sides of the base 1 to move relative to each other under the traction of the two traction lines 7, overcoming the thrust of the outer spring rod 13. This allows the two clamping blocks 4 of the two side rails 3 to move away from each other simultaneously, allowing the disconnector switch body 2 to be hoisted onto the two side rails. Between the two clamping blocks 4 on the side rail 3 and the wide side of the disconnecting switch body 2, the traction head 8 is released. Under the elastic extension and reset action of the outer spring rod 13, the inclined frames 5 on both sides of the base 1 move towards each other. During the process of the inclined frame 5 disengaging from the connecting rod 9, under the tension of the tension rope 15, the two sliding strips 6 inside the side rail 3 drive the corresponding clamping blocks 4 to move and lock the disconnecting switch body 2. By using the bolt 12 to connect the clamping blocks 4 to the corresponding hollowed-out parts on the side rail 3, the relative position of the clamping blocks 4 and the side rail 3 can be fixed. Therefore, the opposite sides of the two side rails 3 are used to prevent the disconnecting switch body 2 from sliding left and right, and the two clamping blocks 4 fixed in the relative position with the side rail 3 are used to fix the front and rear position of the disconnecting switch body 2.

[0031] The wiring diagram of the disconnector switch body 2 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the disconnector switch body 2 will not be explained in detail.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
