Description

Technical Field

[0001] The present invention relates to the technical field of busbar reconstruction and maintenance, and in particular to a busbar fixing and adjusting device adaptable to busbars of different sizes. Background Art

[0002] A busbar in a power system is a conductive material component used to centrally transmit electricity. It's typically made of copper or aluminum. Its primary function is to connect various electrical devices (such as transformers, circuit breakers, and cables) to facilitate the distribution and transmission of electrical energy. In existing power plants, busbar lines are often secured using conventional metal clips, which are then manually tightened with multiple bolts. These clips, with their inherently fixed specifications, are not effective for busbars of varying diameters. Furthermore, tightening these multiple bolts is cumbersome and laborious, especially when busbar lines are located high on poles, amplifying safety risks.

[0003] Therefore, a busbar fixing and adjusting device that can adapt to busbar pipelines of different sizes and still ensure stable clamping, simple and labor-saving operation, and is safe and reliable is needed to meet the needs of existing power plant construction. Summary of the Invention

[0005] In view of the fact that in the above-mentioned prior art, the specification parameters of conventional metal clips themselves are not variable, and their stable clamping effect is not good when facing busbar pipelines of different thicknesses and diameters, and the operation of tightening multiple bolts is relatively cumbersome and laborious, especially when the busbar pipeline is set at a higher pole position, the safety hazard will be further amplified. Therefore, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is to design a busbar fixing and adjusting device that can adapt to busbar pipelines of different sizes and still ensure stable clamping, simple and labor-saving operation, and safe and reliable to meet the needs of existing power plant construction.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a busbar fixing and adjusting device adapted to different sizes, comprising:

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figures 1 to 4 , this embodiment provides a busbar fixing and adjusting device that is adaptable to different sizes.

[0032] The support mechanism 100 stabilizes the entire busbar piping system. A support platform 102 is fixed to the top of the lower chassis 101. Two or three platforms 102 can be installed to meet different needs. A closure sleeve 103 is installed above the support platform 102, one end of which is rotatably connected to the support platform 102. Pulling the closure sleeve 103 causes it to rotate, allowing the busbar piping to be removed or inserted. A locking mechanism 200 ensures that the closure sleeve 103 automatically locks into place once it is rotated, facilitating operation without requiring manual effort to keep the closure sleeve 103 open.

[0033] The rotating shaft 201 is rotatably mounted on the surface of the support platform 102. The outer wall of the rotating shaft 201 is fixedly connected to the closing sleeve 103. The rotation of the rotating shaft 201 allows the closing sleeve 103 to rotate. A plurality of limiting holes 202 are fixedly formed on the surface of the rotating shaft 201, and the limiting holes 202 change position as the rotating shaft 201 moves.

[0034] A connecting rod 203 is slidably disposed on the other side of the rotating shaft 201. The distal end of the connecting rod 203 is disposed on the inner wall of the support platform 102 and is elastically connected thereto. The top end of the connecting rod 203 faces the rotating shaft 201. In the default state, the top end of the connecting rod 203 is fixedly connected to the outer wall of the rotating shaft 201, and the connecting rod 203 is in a compressed state. When the limiting hole 202 follows the movement of the rotating shaft 201, once the limiting hole 202 begins to align with the connecting rod 203, the elastic force previously exerted on the connecting rod 203 is released, allowing the connecting rod 203 to quickly insert into the limiting hole 202. The top end of the connecting rod 203 can be configured as a smooth spherical surface to reduce friction between the connecting rod 203 and the rotating shaft 201, thereby ensuring smoother movement of the connecting rod 203 and the rotating shaft 201.

[0035] The adjustment mechanism 300 ensures the device can better adapt to busbar lines of varying thicknesses. An expansion pack 301 is located at the bottom of the support platform 102. When the busbar line is placed on the bottom of the support platform 102, it can contact the expansion pack 301. A hydraulic assembly 302 is located on the other side of the expansion pack 301, inside the support platform 102. When the closing sleeve 103 rotates and closes to clamp the busbar line, it can contact the hydraulic assembly 302, activating it and pumping hydraulic oil into the expansion pack 301. The increased volume of the expansion pack 301 can lift the busbar line, allowing it to more closely contact the closing sleeve 103, preventing the busbar line from loosening or shaking due to a lack of support points in other directions.

[0036] The inner wall of the closing sleeve 103 is also fixedly provided with a pneumatic component 303 , which can cooperate with the hydraulic component 302 to better stabilize the busbar pipeline.

[0037] Example 2

[0038] Reference Figures 1 to 7 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0039] The support platform 102 has a fixed rotation slot 102a formed on its surface. The rotation shaft 201 is rotatably connected to the rotation slot 102a. The rotation shaft 201 is fixedly connected to the closing sleeve 103, and the outer wall of the rotation shaft 201 is fixedly connected to the closing sleeve 103. The rotation of the rotation shaft 201 allows the closing sleeve 103 to rotate. The support platform 102 also has a fixed groove 102b formed on its surface. This groove 102b is located on one side of the rotation slot 102a. A docking hole 204 is fixedly formed on the sidewall of this groove 102b. This docking hole 204 is connected to the rotation slot 102a, allowing the engaging rod 203 to slide along this docking hole 204. The top end of the engaging rod 203 is in contact with the outer wall of the rotation shaft 201, while the bottom end of the engaging rod 203 is located within an unlocking slot 203a formed on either side of the support platform 102. The unlocking slot 203a is located on the other side of the groove 102b. The bottom end of the engaging rod 203 is elastically connected to the inner wall of the unlocking slot 203a.

[0040] An unlocking lever 203a-1 is slidably disposed within the unlocking slot 203a. The unlocking lever 203a-1 is fixedly connected to the engaging rod 203. Pulling the unlocking lever 203a-1 can cause the engaging rod 203 to move. When the closing sleeve 103 is rotated, the limiting hole 202 gradually aligns with the engaging rod 203 following the movement of the rotating shaft 201. The elastic force previously exerted on the engaging rod 203 is released, and the engaging rod 203 is quickly inserted into the limiting hole 202. To release the engaging rod 203 from the limiting hole 202, simply pull the unlocking lever 203a-1.

[0041] A control opening 102c is fixedly formed on the surface of the rotating groove 102a. This opening extends downward to create a space for the surrounding structure. A transmission ring 201a is fixedly mounted on the surface of the rotating shaft 201 and extends into the control opening 102c. An engaging plate 205 is also slidably disposed at the bottom of the control opening 102c. The transmission ring 201a extends into the control opening 102c and engages with the engaging plate 205. As the transmission ring 201a rotates with the rotating shaft 201, it drives the engaging plate 205 to move horizontally. The other end of the engaging plate 205 is elastically connected to the inner wall of the control opening 102c by a spring 205a having a high elastic coefficient. In the default state, the closing sleeve 103 is closed and in contact with the support platform 102, and the spring 205a is in a relaxed state. When the closing sleeve 103 starts to rotate, the spring 205a is squeezed by the horizontal movement of the engaging plate 205, providing a restoring elastic force.

[0042] A piston 205b is fixedly mounted on the other end of the engagement plate 205. This piston 205b corresponds to an air pressure chamber 206 fixed to the inner wall of the support platform 102. The piston 205b slides horizontally within the air pressure chamber 206, with the outer wall of the piston 205b in contact with the air pressure chamber 206. When the closing sleeve 103 begins to rotate, the engagement plate 205 drives the piston 205b to the right along the air pressure chamber 206, simultaneously compressing the spring 205a. The air pressure chamber 206 is located below the groove 102b. The surface of the groove 102b is provided with an air hole 206a that is connected to the air pressure chamber 206. To reset the closing sleeve 103, simply pull the unlocking lever 203a-1, causing the clamping rod 203 and the limiting hole 202 to shift. The closing sleeve 103 will then slowly return to its original position under the resetting force released by the spring 205a. Since the size of the air hole 206a is very small, the piston 205b will not move very fast to the left along the air pressure chamber 206, and the closing sleeve 103 will not reset very quickly. After the staff releases the unlocking rod 203a-1, they do not have to worry about their hands being hit by the rapid reset of the closing sleeve 103.

[0043] Example 3

[0044] Reference Figures 1 to 6 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0045] A detection airbag 304 is fixedly mounted on the inner surface of the closure sleeve 103. A transmission air pipe 304a is also fixedly mounted on the inner wall of the closure sleeve 103. One end of the transmission air pipe 304a is fixedly connected to the detection airbag 304, and the other end is connected to the auxiliary airbag 305a. A regulating cavity 305 is fixedly defined on the other side of the closure sleeve 103, and the auxiliary airbag 305a is located within the regulating cavity 305. When the closure sleeve 103 begins to contact the busbar pipeline during the reset process, the radius of the busbar pipeline is relatively large, ensuring that the closure sleeve 103 can securely clamp the busbar pipeline without the intervention of the hydraulic assembly 302. During the reset process of the closure sleeve 103, the detection airbag 304 is gradually squeezed by the busbar pipeline. To maintain constant air pressure, the compression and shrinkage of the detection airbag 304 causes the auxiliary airbag 305a to expand and expand through the transmission air pipe 304a.

[0046] The outer wall of the auxiliary airbag 305a is sheathed with a clamping block 306, with a tension spring 306a fixed between the clamping blocks 306. When the auxiliary airbag 305a expands, it drives the clamping blocks 306, pulling the tension spring 306a apart. Once the clamping blocks 306 separate, space is vacated at the bottom of the adjustment cavity 305. The surface of the support platform 102 is provided with an accommodating annular groove 102d for accommodating busbar piping. When the closing sleeve 103 begins to approach the surface of the support platform 102, the space vacated in the adjustment cavity 305 accommodates the starting plug 302a, preventing it from being pressed downward and preventing the hydraulic assembly 302 from being activated. At this point, the closing sleeve 103 and the accommodating annular groove 102d are sufficiently engaged to accommodate the busbar piping.

[0047] If the radius of the busbar is relatively small, the detection airbag 304 will not be squeezed, the auxiliary airbag 305a will not expand, and the clamp 306 will remain in place, leaving no space for the start plug 302a. The start plug 302a will be squeezed and move downward during the movement of the closing sleeve 103.

[0048] The expansion pack 301 is fixed on the surface of the accommodating annular groove 102d, and a starting plug 302a is slidably provided on one side of the accommodating annular groove 102d. The downward pressure of the starting plug 302a can drive the hydraulic component 302 to start, and the hydraulic oil is input into the expansion pack 301, so that the expansion pack 301 becomes larger and lifts up, pushing the busbar pipeline to lift and contact the detection airbag 304 as much as possible, ensuring that when the busbar pipeline is small in size, it can still be effectively stabilized in the device and will not loosen. The side wall of the starting plug 302a is elastically connected to the inner wall of the supporting platform 102. When the closing sleeve 103 is pulled and lifted by the staff, the starting plug 302a will be reset under the action of the elastic force and wait for the next operation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
