[0028] Example 1

[0029] Reference Figure 1-3 , which is the first embodiment of the present invention, provides a short-circuiting device for a T-type wire clamp with abnormal temperature in a substation, the device comprising a locking unit 100, comprising a special-shaped duckbill clamp 101, and a clamping portion 102 arranged on the special-shaped duckbill clamp 101. The special-shaped duckbill clamp 101 of the locking unit 100 is designed so that the device can firmly clamp the T-type wire clamp, and the arrangement of the clamping portion 102 makes the structure of the entire device more compact, and is convenient for operation and installation;

[0030] The conversion unit 200 includes a protective shell 201 arranged on the clamping part 102, and a conversion part 202 arranged on the protective shell 201. The protective shell 201 is arranged on the clamping part 102, which provides an additional layer of protection for the operator to prevent accidental electric shock during operation, thereby improving the safety of the operation. The setting of the conversion unit 200 enables the device to adapt to different operating environments and requirements, and is convenient for the staff to quickly switch the device on different power equipment, thereby improving the adaptability and efficiency of the operation. Through the coordinated work of the locking unit 100 and the conversion unit 200, the short-circuiting operation of the T-type wire clamp can be quickly completed, reducing the power outage time caused by abnormal heating of the equipment, thereby improving the reliability and work efficiency of the power grid operation.

[0031] The bottom of the special-shaped duckbill clamp 101 is provided with a mounting block 103, the top of the special-shaped duckbill clamp 101 is arranged in an arc shape, and the head of the special-shaped duckbill clamp 101 is provided with a guide block 104. The mounting block 103 provides a stable fixing point, so that the special-shaped duckbill clamp 101 can be firmly installed on the T-shaped wire clamp or other equipment, ensuring the stability and reliability of the short-circuit device. The arc-shaped top design enables the special-shaped duckbill clamp 101 to better adapt to the contour of the clamped object when clamping, reduce the friction during clamping, make the operation smoother, and also reduce the risk of damage to the clamped object. The arc-shaped design It can usually provide better clamping force distribution, making the clamping more secure and reducing the risk of loosening under high load or vibration conditions. The guide block 104 on the head helps to provide precise guidance during the installation process, ensuring that the special-shaped duckbill clamp 101 can correctly position and clamp the T-type wire clamp, thereby improving the accuracy and efficiency of installation. The design of the mounting block 103 and the guide block 104 can enhance the structural strength of the entire duckbill clamp, improve its durability and service life, especially in frequent use or harsh environments. This helps to reduce maintenance requirements because there are fewer wearing parts and they are easier to replace, reducing the labor intensity of staff.

[0032] The clamping part 102 includes a clamping assembly 102a disposed on the special-shaped duckbill clamp 101, and an adjusting assembly 102b disposed on the clamping assembly 102a. The clamping assembly 102a is directly disposed on the special-shaped duckbill clamp 101, which can provide accurate and stable clamping force to ensure the safety of the T-type wire clamp or other equipment during the short-circuit process. The setting of the adjusting assembly 102b facilitates the operator to adjust the clamping force and position according to actual needs to adapt to T-type wire clamps of different specifications and shapes, thereby improving the adaptability and versatility of the device. The adjusting assembly 102b enables the clamping part 102 to better contact with the T-type wire clamp, reducing the problem of poor contact or excessive resistance, thereby improving the efficiency and safety of power transmission. The precise clamping and adjustment capabilities reduce unnecessary pressure and damage to the T-type wire clamp, extending the service life of the equipment.

[0033] During use, the staff can quickly deploy the short-circuit device to the T-type wire clamp or other equipment by adjusting the clamping force. Clamping and adjustment can be achieved through simple rotation or sliding movements without the need for complicated tools or steps. The design of the protective shell 201 provides additional protection for the operator to prevent direct contact with live parts in a high-voltage environment, reducing the risk of electric shock. The combination of the clamping component 102a and the adjustment component 102b enables the device to adapt to T-type wire clamps of different specifications and shapes, thereby improving the flexibility of operation.

[0034] Example 2

[0035] Reference Figure 1-3, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the clamping assembly 102a includes a sliding rod 102a-1 inserted on the mounting block 103, a clamping block 102a-2 arranged on the sliding rod 102a-1, and an arc block 102a-3 arranged on the clamping block 102a-2. The design of the sliding rod 102a-1 allows the clamping block 102a-2 to move freely within a certain range, so that the clamping portion 102 can be flexibly adjusted according to the shape and size of different T-type wire clamps or equipment, thereby improving adaptability. The design of the arc block 102a-3 matches the shape of the T-type wire clamp, which can provide Provide a better contact surface, enhance the clamping effect, and reduce the problem of poor contact caused by improper clamping. Through the setting of the sliding rod 102a-1, the operator can easily adjust the position of the clamping block 102a-2, which simplifies the clamping process, reduces the operating steps, and improves work efficiency. The design of the arc block 102a-3 can evenly distribute the clamping force on the contact surface, reduce local pressure concentration, and reduce the risk of damage to the clamped object. The combined design of the clamping block 102a-2 and the arc block 102a-3 provides a more stable clamping force, reduces the risk of loose clamping under high load or vibration conditions, and thus improves the safety of the operation.

[0036] Compared with Example 1, further, the curvature of the surface of the arc block 102 a - 3 corresponds to the curvature of the surface of the special-shaped duckbill clamp 101 .

[0037] Compared with Example 1, further, the adjustment component 102b includes a positioning ring 102b-1 arranged below the sliding rod 102a-1, and an insulating gasket 102b-2 is attached to the inner wall of the positioning ring 102b-1. The corresponding design of the arc block 102a-3 and the surface curvature of the special-shaped duckbill clamp 101 ensures a perfect fit between the two, provides a larger contact area, and thus enhances the stability and reliability of the clamping. Better contact surface fit can effectively reduce contact resistance, improve power transmission efficiency, and reduce the risk of damage caused by poor contact. The design of the arc block 102a-3 makes the clamping force evenly distributed on the contact surface, avoiding local pressure concentration, reducing potential damage to the T-type wire clamp, and extending the service life of the equipment. Since the arc block 102a-3 matches the surface of the special-shaped duckbill clamp 101, the clamping effect is better, and it can maintain a stable clamping state under high load and vibration conditions, reducing the risk of loosening. At the same time, it allows operators to install and disassemble more smoothly, reducing the adjustment time caused by mismatch and improving work efficiency.

[0038] Compared with Example 1, further, the conversion part 202 includes a conversion component 202a arranged on the protective shell 201, and a rotating component 202b arranged on the conversion component 202a. The rotating component 202b enables the conversion part 202 to perform multi-angle rotation operations, thereby improving the flexibility and adaptability of the device. At the same time, the rotating component 202b can adjust the angle of the clamping component 102a to ensure that a stable clamping force can be provided in different directions, thereby enhancing the stability of the clamping. The design of the rotating component 202b allows the operator to operate without directly contacting the high-voltage equipment, thereby improving the safety of the operation.

[0039] Compared with Example 1, further, the conversion assembly 202a includes an operating rod 202a-1 arranged inside the protective shell 201, and a driven gear 202a-2 arranged on the operating rod 202a-1. The design of the operating rod 202a-1 enables the operator to operate the short-circuiting device more conveniently, especially when space is limited or direct contact is difficult, thereby enhancing the flexibility of operation. The driven gear 202a-2 can amplify the power of the operating rod 202a-1 and reduce the force required by the operator, thereby making the clamping and adjustment process easier and reducing operator fatigue. Through the combined design of the operating rod 202a-1 and the driven gear 202a-2, the operator can complete the short-circuiting operation more quickly and improve the overall work efficiency, especially when the clamping position needs to be adjusted frequently.

[0040] Compared with Example 1, further, the rotating component 202b includes a driving gear 202b-1 meshing with the surface of the driven gear 202a-2, a rotating rod 202b-2 connected to the driving gear 202b-1, and a rotating thread 202b-3 arranged on the surface of the rotating rod 202b-2. The meshing of the driving gear 202b-1 and the driven gear 202a-2 can amplify the operating force, reduce the force required to be applied by the operator, and improve the operating efficiency. At the same time, the design of the rotating thread 202b-3 can provide a self-locking function when necessary to ensure that the clamping component 102a will not loosen due to vibration or accidental operation after being adjusted to a specific position, and it is convenient for the operator to make fine adjustments and accurately control the position of the clamping component 102a to adapt to different working conditions, so that the operator can operate without directly contacting the high-voltage equipment, thereby improving the safety of the operation.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figure 1-3, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: a positioning ring 102b-1 is provided on the side of the rotating rod 202b-2 away from the driving gear 202b-1, providing an additional fixing point to ensure the precise positioning of the rotating rod 202b-2 during operation, thereby improving the operating accuracy of the entire device, and can also reduce the direct contact between the rotating rod 202b-2 and other components, reduce wear, and extend the service life of the components. At the same time, it avoids the accidental slipping of the rotating rod 202b-2 during operation, and improves the safety of operation.

[0044] Compared with Example 2, further, the locking unit 100 is provided with two groups, wherein one special-shaped duckbill clamp 101 is used to clamp the horizontal direction of the T-shaped wire clamp, and the other special-shaped duckbill clamp 101 is used to clamp the vertical part below the T-joint of the T-shaped wire clamp. Through the design of two groups of special-shaped duckbill clamps 101, the two directions of the T-shaped wire clamp can be clamped more stably, thereby improving the stability and safety of the device, ensuring the stable connection of the T-shaped wire clamp under high load or vibration conditions, and at the same time enabling the device to adapt to different installation angles of the T-shaped wire clamp, providing effective clamping in both horizontal and vertical directions, thereby improving work efficiency and enhancing the versatility of the equipment.
