Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection, in particular to a contactor for lightning protection grounding test. Background Art

[0002] With the frequent occurrence of lightning disaster accidents and the continuous deepening of lightning protection social management work in recent years, lightning protection safety has received more and more social attention. Especially for lightning protection safety in inflammable and explosive places, even a little negligence may cause casualties to detection personnel.

[0003] For example, the patent application number is CN202222338175.6. The utility model belongs to the field of lightning science and technology, and particularly relates to a contactor for lightning protection grounding test, including a handle and a contact head. The contact head is arranged at the bottom of the handle. A contact connection device and a steel rod connection device are arranged at the bottom of the handle. The contact connection device includes a T-shaped groove, a fan-shaped groove, a first T-shaped slider, a metal contact head, a triangular pyramid, a saw blade part, a flat file part, and a contact head protection sleeve. The steel rod connection device includes a grounding steel rod, a second T-shaped slider, a diamond-shaped plug, a U-shaped rod, a straight rod, and a steel rod protection sleeve. For this contactor for lightning protection grounding test, by the combined use of a clamping plate and a connection hole, a wiring terminal is connected to the device. By opening a T-shaped groove and a fan-shaped groove at the bottom of the handle, the first T-shaped slider at the top of the metal contact head is placed inside the T-shaped groove, and the first T-shaped slider is rotated to slide to the bottom of the fan-shaped groove, ensuring the firmness of their connection.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that although the above equipment can solve the problem that for most ordinary grounding steel rods in lightning protection grounding test detection, the effective conduction connection is achieved by using sockets or clips, and the handheld metal contact head is a round file head. For some test objects, due to long installation time, exposure to the air, lack of maintenance and other reasons, they are corroded. When it is necessary to polish the surface rust, the round file is likely to cause large-area scratches or even damage to the metal surface of the object to be measured during the process of attempting metal contact conduction. However, during the use process, it is usually inserted into the soil for testing. After being inserted into the soil, it will cause the surrounding soil particles to rearrange, thereby increasing the porosity of the soil and making the soil structure become relatively loose. And the device does not have a support structure, so the device will loosen during use, having certain limitations. Summary of the Utility Model

[0014] 1. By setting the reinforcement cylinder, the reinforcement cylinder cooperates with the spiral earth drilling rod to assist in reinforcing the contact connection device, solving the problem that during use, it is usually inserted into the soil for testing. After being inserted into the soil, it will cause the surrounding soil particles to rearrange, thereby increasing the porosity of the soil and making the soil structure become relatively loose.

[0024] As a technical optimization scheme of the present invention, by setting the rotating assembly 11, the rotating disc 111 can drive the rotating pin 113 to move inside the rotating threaded groove 112 after moving downward, so that the rotating pin 113 can drive the rotating disc 111 to rotate along with the rotating threaded groove 112, so that the rotating disc 111 can drive the spiral ground drilling rod 10 to rotate while moving downward.

[0025] Referring to Figure 3 , the transmission assembly 12 includes a transmission threaded groove 121. The transmission threaded groove 121 is opened on the surface of the reinforcing cylinder 9. A transmission nut 122 is threadedly connected to the reinforcing cylinder 9 through the transmission threaded groove 121. A transmission rod 123 is fixedly connected to the top of the inner wall of the transmission nut 122.

[0026] As a technical optimization solution of the present utility model, by providing a transmission assembly 12, the transmission sleeve 122 rotates and moves downward on the surface of the reinforcement cylinder 9 through the transmission thread groove 121, so that the transmission sleeve 122 drives the transmission rod 123 to move downward, and the downward movement of the transmission rod 123 drives the rotating disk 111 to move downward.

[0027] Reference Figure 3 , a flat bearing 13 is fixedly embedded at the top of the rotating disk 111, and the top ring of the flat bearing 13 is fixedly connected to the bottom end of the transmission rod 123.

[0028] As a technical optimization solution of the present utility model, by providing the flat bearing 13, the use of the flat bearing 13 can reduce the friction between the transmission rod 123 and the rotating disk 111, making the movement of the rotating disk 111 smoother and more stable.

[0029] Reference Figure 3 , anti-slip grooves 14 are formed on the surface of the transmission sleeve 122, and a plurality of anti-slip grooves 14 are formed and distributed at equal intervals in a ring shape.

[0030] As a technical optimization solution of the present utility model, by providing the anti-slip grooves 14, the use of the anti-slip grooves 14 can increase the friction between the user's hand and the transmission sleeve 122, thereby preventing the hand from slipping off the transmission sleeve 122 when the user rotates the transmission sleeve 122.

[0035] Working principle and usage process of the present utility model: During use, rotate the reinforcement cylinder 9 so that the bottom of the reinforcement cylinder 9 faces the ground. Then, rotate the transmission screw sleeve 122 on the surface of the reinforcement cylinder 9, so that the transmission screw sleeve 122 moves downward through the transmission thread groove 121 on the surface of the reinforcement cylinder 9. After the transmission screw sleeve 122 moves downward, it can drive the transmission rod 123 to move downward, and the transmission rod 123 drives the rotating disk 111 inside the reinforcement cylinder 9 to move downward. When the rotating disk 111 moves downward, it will drive the spiral earth drill rod 10 to move downward, and at the same time, it will drive the rotating pin 113 to move inside the rotating thread groove 112. Thus, the cooperation between the rotating thread groove 112 and the rotating pin 113 can drive the rotating disk 111 and the spiral earth drill rod 10 to rotate. Therefore, while the spiral earth drill rod 10 moves downward, it drills into the ground. After the spiral earth drill rod 10 drills into the ground, it cooperates with the reinforcement cylinder 9 to reinforce the contact connection device 4, ensuring the stability of the contact connection device 4 during use.

[0036] In summary: For this lightning protection grounding test contactor, by setting the reinforcement cylinder 9, the reinforcement cylinder 9 cooperates with the spiral earth drill rod 10 to assist in reinforcing the contact connection device 4, solving the problem that during use, it is usually inserted into the soil for testing. After being inserted into the soil, it will cause the surrounding soil particles to rearrange, thereby increasing the porosity of the soil and making the soil structure become relatively loose. And this device does not have a support structure, resulting in the device being loose during use, having certain limitations.
