[0039] Example 1:

[0040] This embodiment provides a foreign object clamping device for lead-acid batteries, such as... Figure 1-2 As shown, it specifically includes a gripping head assembly 1, a linkage assembly 2, a handle assembly 3, and a bellows housing 4.

[0041] The gripping head assembly 1 of this embodiment is used to grip foreign objects inside a lead-acid battery. Specifically, it includes a connector 11 and several connecting plates 12 evenly distributed on the top of the connector 11. A through channel is formed between the connector 11 and the connecting plates 12 along the axial direction, providing effective axial space for the operation of the linkage assembly 2. In this embodiment, grippers 13 are rotatably provided between adjacent connecting plates 12.

[0042] The linkage component 2 in this embodiment is used to drive the grippers 13 to move closer or further apart. Specifically, it includes a moving block 21, a hinge seat 22, a return spring 23, and a connecting line 24. In this embodiment, the moving block 21 is located in the through channel, and the hinge seat 22 is located at the top of the moving block 21, with a plurality of hinge pieces 25 evenly distributed on the hinge seat 22. Each gripper 13 is rotatably connected to one of the hinge pieces 25. One end of the connecting line 24 is connected to the moving block 21, and the other end is connected to the handle assembly 3.

[0043] The handle assembly 3 in this embodiment includes a fixed handle 31 and a pressing handle 32. The fixed handle 31 is connected to the connector 11 of the gripping head assembly 1 by a bellows shell 4, and the pressing handle 32 is connected to the connecting wire 24.

[0044] This embodiment cleverly assembles the connector 11, connecting plate 12, and gripper 13 to form a gripping head assembly 1 capable of grasping foreign objects. A linkage assembly 2 connecting the gripping head assembly 1 and the handle assembly 3 is formed by the combination of the moving block 21, hinge seat 22, return spring 23, connecting wire 24, and hinge piece 25. A bendable and adjustable middle section is formed by the corrugated shell 4 connecting the gripping head assembly 1 and the handle assembly 3, allowing for flexible adjustment of the direction and angle of the middle section. Through the coordinated use of the gripping head assembly 1, linkage assembly 2, handle assembly 3, and corrugated shell 4, this embodiment enables effective and precise grasping of foreign objects from lead-acid batteries through simple gripping and pressing operations.

[0045] Example 2:

[0046] This embodiment provides a foreign object grasping device for lead-acid batteries, including a grasping head assembly 1, a linkage assembly 2, a handle assembly 3, and a corrugated pipe shell 4.

[0047] In this embodiment, the gripping head assembly 1, the linkage assembly 2, the handle assembly 3, and the bellows housing 4 are all made of acid-resistant polytetrafluoroethylene. The gripping device in this embodiment uses an insulating, acid-resistant material, which will not cause a short circuit in the battery's internal plates even if it comes into contact with them. Furthermore, the acid-resistant material does not contain chloride ions and will not chemically react with the battery electrolyte, thus preventing contamination of the battery electrolyte.

[0048] like Figure 1-5 As shown, the gripping head assembly 1 of this embodiment is used to grip foreign objects inside a lead-acid battery. Specifically, it includes a connector 11 and four connecting plates 12 evenly distributed at the top of the connector 11. Each connecting plate 12 has an L-shaped structure with an arc transition. A through channel is formed axially between the connector 11 and the connecting plates 12, providing effective axial space for the operation of the linkage assembly 2. Adjacent connecting plates 12 are rotatably connected by conventional rotating fasteners, such as pins or bolts. The gripping surfaces of the grippers 13 are provided with anti-slip textures 131, which are either continuously or intermittently arranged in a serrated shape to increase friction and stability during gripping.

[0049] The linkage component 2 in this embodiment is used to drive the grippers 13 to move closer or further apart. Specifically, it includes a moving block 21, a hinge seat 22, a return spring 23, and a connecting wire 24. In this embodiment, the moving block 21 is located in the through channel, and the hinge seat 22 is located at the top of the moving block 21, with a plurality of hinge plates 25 evenly distributed on the hinge seat 22. Each gripper 13 is rotatably connected to a hinge plate 25. In this embodiment, the number of hinge plates 25, connecting plates 12, and grippers 13 are equal. The middle part of each gripper 13 is hinged to an adjacent connecting plate 12 to achieve rotation, and the end of each gripper 13 is hinged to a hinge plate 25 to achieve rotation. In this embodiment, one end of the return spring 23 is connected to a protruding ring 211 on the moving block 21, and the other end is connected to the inner wall of a groove in the connecting head 11.

[0050] In this embodiment, one end of the connecting line 24 is connected to the moving block 21, and the other end is connected to the handle assembly 3. The connecting line 24 is an elastic connecting line, such as a metal cable that has both strength and bendability.

[0051] The handle assembly 3 of this embodiment includes a fixed handle 31 and a pressing handle 32. A bellows housing 4 connects the fixed handle 31 to the connector 11 of the gripping head assembly 1. The pressing handle 32 is connected to a connecting line 24. The fixed handle 31 includes an integrally connected fixed housing 311 and a gripping handle 312. The fixed housing 311 has a hollow structure and is connected to the bellows housing 4 with a sealed connection. The pressing handle 32 includes a handle connecting part 321 movably disposed within the fixed housing 311 and a pressing part 322 disposed outside the fixed housing 311. The handle connecting part 321 and the pressing part 322 are integrally connected. The handle connecting part 321 is connected to the connecting line 24, and the pressing part 322 has a finger slot for easy gripping.

[0052] The method of using the clamping device in this embodiment specifically includes the following steps:

[0053] S1, set the bellows housing 4 to a predetermined direction and angle to ensure that it approaches the foreign object in the simplest way;

[0054] S2, hold the handle assembly 3 and insert the bellows shell 4 and gripping head assembly 1 of the clamping device in this embodiment into the lead-acid battery.

[0055] S3, the gripping head assembly 1 slowly approaches the foreign object, so that the gripping head assembly 1 is completely close to the foreign object;

[0056] S4, grip the handle assembly 3 tightly so that the gripping head assembly 1 completely covers the foreign object;

[0057] S5. Slowly pull out the gripping device. Before the tool is completely removed from the lead-acid battery, drain the acid on the surface as much as possible to complete the foreign object gripping work.

[0058] The clamping device of this embodiment has achieved the expected results during the overhaul of the nuclear island of a nuclear power plant. After simulating high-frequency use tests (50 times / day), most components remained in good working order after 3 weeks, with only some connecting parts showing slight wear, which did not affect the long-term accuracy.

[0059] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
