Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a safety detection device for a fire-fighting weak current project, including a housing 1, the inside of the housing 1 is fixedly welded to the outside of a bearing sleeve 2, the bearing sleeve 2 is fixedly welded to the outside of a sleeve 3, the sleeve 3 is rotatably connected to the inner wall of the housing 1 through the bearing sleeve 2, the top of the sleeve 3 is fixedly welded to a rotating cylinder 4, anti-slip grooves are formed on the side surface of the rotating cylinder 4, the inside of the rotating cylinder 4 is hollow, the inside of the sleeve 3 is threadedly connected to the outside of a lifting cylinder 5, the bottom of the lifting cylinder 5 is hinged to one end of two symmetric connecting plates 6 through a hinge groove, the bottom of the housing 1 is hinged to two symmetric sealing plates 7, the sealing plates 7 are sector plates, the outside of the sealing plates 7 is adhesively fixed to a sealing ring, the upper surface of the sealing plates 7 is fixedly welded to a slide rail 8, the slide rail 8 is a T-shaped plate, the outside of the slide rail 8 is slidably connected to a T-shaped mating groove inside a slider 9, two chutes 10 are formed on the side surface of the lifting cylinder 5, the number of the chutes 10 is two and they are symmetrically distributed on the inner wall of the lifting cylinder 5, the chutes 10 are vertically arranged on the inner wall of the lifting cylinder 5, a fixing groove 11 is formed on the side surface of the lifting cylinder 5, the fixing groove 11 is an L-shaped groove, the fixing groove 11 communicates with the inside of the chute 10, the inside of both the chute 10 and the fixing groove 11 is slidably connected to the outside of a slide bar 13, the inside of the lifting cylinder 5 is slidably connected to the outside of a mounting plate 12, the outside of the mounting plate 12 is fixedly welded to the slide bar 13, the bottom of the mounting plate 12 is fixedly welded to a test needle 14, a spring 15 is sleeved inside the rotating cylinder 4,
[0023] The housing 1 is a cylinder that runs through vertically. The housing 1 is rotatably connected to the sleeve 3 through the bearing sleeve 2. The bottom of the housing 1 is hinged to the outer sides of two symmetric sealing plates 7 through the hinge groove. Thread grooves are provided inside the sleeve 3, and threads are provided on the outer side of the lifting cylinder 5. The lifting cylinder 5 is threadedly connected to the inner wall of the sleeve 3 through the threads. One end of the connecting plate 6 is hinged to the hinge groove at the bottom of the lifting cylinder 5, and the other end of the connecting plate 6 is hinged to the inside of the slider 9. A mating groove is provided at the bottom of the slider 9, and the slider 9 is slidably connected to the outer side of the slide rail 8 through the mating groove. Rotating the rotating cylinder 4 causes the sleeve 3 to rotate synchronously. Through the thread groove on the inner wall of the sleeve 3, the lifting cylinder 5 moves downward on the inner wall of the sleeve 3. The downward movement of the lifting cylinder 5 will push the connecting plates 6 on both sides, causing the sealing plates 7 to rotate. While the two connecting plates 6 are slowly opened, the lifting cylinder 5 will drive the test probe 14 to move downward until it moves out of the housing 1. Weak current detection can be carried out by abutting the test probe 14 against the target. Conversely, rotating the rotating cylinder 4 can retract the test probe 14 into the housing 1, and at the same time, cause the sealing plates 7 on both sides to rotate and close the bottom of the housing 1, avoiding the situation that the test probe 14 is contaminated or even rusted due to environmental factors;
[0024] The sliding groove 10 is a straight groove, and the fixing groove 11 is a rectangular groove. The fixing grooves 11 are evenly distributed in a linear array on one side of the sliding groove 10. The fixing grooves 11 communicate with the inside of the sliding groove 10. Both ends of the spring 15 are welded and fixed to the rotating cylinder 4 and the mounting plate 12 respectively. The outer side of the mounting plate 12 is slidably connected to the inside of the lifting cylinder 5. Rotating the test probe 14 drives the mounting plate 12, causing the sliding rod 13 to enter the sliding groove 10 from the inside of the fixing groove 11. After moving the test probe 14 to the target length, rotating the mounting plate 12 causes the sliding rod 13 to enter the corresponding fixing groove 11. The sliding rod 13 is fixed inside the L-shaped fixing groove 11 by the elastic force of the spring 15, thereby realizing the length adjustment of the test probe 14;
[0025] Working principle: When in use, the staff rotates the rotating cylinder 4 to synchronously rotate the sleeve 3. Through the thread groove on the inner wall of the sleeve 3, the lifting cylinder 5 moves downward on the inner wall of the sleeve 3. The downward movement of the lifting cylinder 5 will push the connecting plates 6 on both sides, causing the sealing plate 7 to rotate. While the connecting plates 6 on both sides are slowly opened, the lifting cylinder 5 will drive the test needle 14 to move downward until it moves out of the housing 1. Weak current detection can be carried out by making the test needle 14 contact with the target. When it is necessary to adjust the length of the test needle 14, rotate the test needle 14 to drive the mounting plate 12, so that the sliding rod 13 enters the chute 10 from the inside of the fixing groove 11. After moving the test needle 14 to the target length, rotate the mounting plate 12 to make the sliding rod 13 enter the corresponding fixing groove 11. The elastic force of the spring 15 fixes the sliding rod 13 inside the L-shaped fixing groove 11, thus realizing the length adjustment of the test needle 14. After the test needle 14 is used up, rotate the rotating cylinder 4 in the reverse direction to make the lifting cylinder 5 move upward, further driving the connecting plate 6 to make the sealing plate 7 rotate. When the test needle 14 is retracted into the housing 1, the sealing plates 7 on both sides continue to rotate until they abut against each other to close the bottom of the housing 1, realizing the retraction of the test needle 14 and improving the protection effect on the test needle 14.
