DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0032] This embodiment is a lightning arrester for an integrated logging instrument for oil fields that is easy to install.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, the front side of the base 1 is rotatably connected to the turning handle 2, and the rear side of the turning handle 2 is fixedly connected to the gear 3. The gear 3 is meshed with the lower telescopic plate 4 through a toothed plate. The internal thread of the lower telescopic plate 4 is connected to a threaded rod 5. The lower side of the threaded rod 5 is rotatably connected to the anti-skid plate 6, and the anti-skid plate 6 is slidably connected to the lower telescopic plate 4. In addition, the gear 3 is meshed with the upper telescopic plate 7 through a toothed plate. The lower side of the upper telescopic plate 7 is also provided with a threaded rod 5 and an anti-skid plate 6. A telescopic column 8 is provided on the upper side of the base 1, and a support platform 9 is provided on the upper side of the telescopic column 8.

[0034] like Figure 1 and Figure 4As shown, the upper side of the support platform 9 is fixedly connected to a support plate 10, and the support plate 10 is symmetrical about the vertical center axis of the support platform 9. The right side of the support plate 10 on the upper left side of the support platform 9 is fixedly connected to a connecting column 11, and the left side of the support plate 10 on the upper right side of the support platform 9 is fixedly connected to a threaded column 12. The threaded column 12 is threadedly connected to the first sleeve 13. The first sleeve 13 is fixedly mounted on the inner side of the first shielding cover 14. The first sleeve 13 is symmetrical about the vertical center axis of the first shielding cover 14. The first sleeve 13 is rotatably connected to the connecting column 11. In addition, the threaded column 1 2 is threadedly connected to the second sleeve 15, and the second sleeve 15 is fixedly mounted on the outside of the second shielding cover 16. The second shielding cover 16 is bilaterally symmetrical about the vertical center axis of the second sleeve 15. The second sleeve 15 is rotatably connected to the connecting column 11. In addition, the internal thread of the first sleeve 13 and the internal thread of the second sleeve 15 are arranged in opposite directions, and the threaded column 12 is rotatably connected to the support plate 10. An opening 17 is provided in the interior of the threaded column 12. A connecting hole 18 is provided on the side of the support plate 10 on the upper right side of the support platform 9. A latch 19 is slidably connected to the interior of the opening 17 and the connecting hole 18.

[0035] It should be noted that the telescopic column 8 can be extended and retracted, and the distance between the base 1 and the support platform 9 can be adjusted as needed, so as to facilitate the lightning protection function for oil field logging and increase safety. Specific embodiment 2

[0036] This embodiment is intended to solve the problem of a small contact area between the base 1 and the ground.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, place the base 1 on the ground and then install it on the ground. Since the base 1 is small, the contact area between the base 1 and the ground is small when encountering strong winds. Turn the handle 2 to allow the lower telescopic plate 4 and the upper telescopic plate 7 to move outward synchronously, and then rotate the threaded rod 5 on each of them. Since the threaded rod 5 is threadedly connected to the lower telescopic plate 4, the anti-skid plate 6 is rotatably connected to the threaded rod 5. Therefore, the rotating threaded rod 5 will allow the lower side of the anti-skid plate 6 to contact the ground, thereby achieving the purpose of increasing the contact between the base 1 and the ground. When encountering strong winds, the pressure on the base 1 will be distributed through the anti-skid plate 6, thereby increasing safety, and facilitating installation and use. Specific embodiment three

[0038] This embodiment is intended to solve the problem of the inconvenience of exposing and closing the lightning protection ball during movement.

[0039] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, when moving the device, since the outer end of the lightning arrester is provided with a lightning rod, it is easy to prick workers. The protective cover and the device are not integrated, and the installation is relatively troublesome. When using the lightning arrester for lightning protection, the pin 19 is lifted from the opening 17, and the first shielding cover 14 and the second shielding cover 16 will fall under the action of gravity, and will also rotate with the threaded column 12. The interior of the first shielding cover 14 and the second shielding cover 16 are provided with arc grooves to avoid clamping the lead. When the device needs to be carried, the threaded column 12 is rotated. Since the first set The thread inside the tube 13 is set in the opposite direction to the thread inside the second sleeve 15. When the threaded column 12 is rotated, the first shielding cover 14 and the second shielding cover 16 will rotate upward until the first shielding cover 14 and the second shielding cover 16 are fitted together, and then the pin 19 is reinserted into the opening 17 and the connecting hole 18 to prevent the first shielding cover 14 and the second shielding cover 16 from being disconnected. It is very convenient to use. In addition, the connecting hole 18 limits the pin 19 to prevent the threaded column 12 from rotating, thereby playing a protective role.
