DETAILED DESCRIPTION

[0036] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0037] Please refer to Figs. 1 to 4The mine water level monitoring mechanism in the embodiment comprises a main cylinder 1, a blocking cover 2, a floating ball piece 3, and a light touch switch 4. The bottom end of the main cylinder 1 is inserted into the inner wall of the blocking cover 2. A plurality of water inlet holes are formed on the outer surface of the main cylinder 1. The water inlet holes are located at the blocking cover 2 and are equally distributed in a ring shape. The blocking cover 2 can block the relatively large impurities in the mine water to prevent the water inlet holes from being blocked. The floating ball piece 3 is located inside the main cylinder 1, and the light touch switch 4 is installed on the top of the main cylinder 1.

[0038] The floating ball piece 3 comprises a limiting rod 301, a sleeve 302, a floating ball body 303, two fixing rods 304, a floating ring 305, and a touch plate 306. The limiting rod 301 is fixed to the inner top wall of one of the half cylinders. The sleeve 302 is slidably connected to the outer surface of the limiting rod 301. The floating ball body 303 is fixedly connected to the outer surface of the sleeve 302. The two fixing rods 304 are fixedly connected to the two sides of the sleeve 302. The inner side of the floating ring 305 is fixedly connected to one end of the two fixing rods 304. The touch plate 306 is fixedly connected to the top of the fixing rod 304 and is in the shape of a ring, located below the light touch switch 4.

[0039] The water enters the inside of the main cylinder 1 through the water inlet holes of the main cylinder 1. The floating ball body 303 and the floating ring 305 are both made of plastic. When the water level rises, the floating ball body 303 and the floating ring 305 will move upwards until the touch plate 306 touches the light touch switch 4 on the main cylinder 1. The light touch switch 4 is electrically connected to the alarm, so that the alarm can be triggered.

[0040] The main cylinder 1 is composed of two half cylinders. An exhaust hole is formed on the top of one of the half cylinders. Insertion holes are formed on the bottom of the two half cylinders. An insertion rod is fixedly connected to the inner bottom wall of the blocking cover 2 and corresponds to the insertion holes. When the water enters the inside of the main cylinder 1, the gas can be discharged from the exhaust hole to ensure that the air pressure inside the main cylinder 1 is consistent with the outside, which facilitates the water to enter the main cylinder 1. The insertion rod is inserted into the insertion hole, which facilitates the splicing and limiting of the two half cylinders.

[0041] The surface of the main body cylinder 1 and the barrier cover 2 is provided with a connecting assembly 5, which is used for fixing and adjusting the two half cylinders of the main body cylinder 1. The connecting assembly 5 comprises a support plate 501, an upper connecting plate 502, a lower connecting plate 503, a threaded rod 504, a threaded cylinder 505, a support rod 506, a sliding rail 507, a sliding block 508 and a connecting rod 509. The support plate 501 is L-shaped and is inserted and fixed with the ground. The bottom of the support plate 501 is provided with an insertion column, and the support plate 501 is inserted into the ground of the mine through the insertion column, so that the support plate 501 is fixed. The upper connecting plate 502 is installed at the top of the two half cylinders, and the lower connecting plate 503 is installed at the bottom of the barrier cover 2. The lower connecting plate 503 is fixed with the proximal end of the upper connecting plate 502 and is fixed by bolts, so as to facilitate the disassembly of the upper connecting plate 503 and the lower connecting plate 503. The top of the two half cylinders and the bottom of the barrier cover 2 are both fixedly connected with an insertion column, and the outer surface of the insertion column is threadedly connected with a nut. The insertion column is used for limiting the upper connecting plate 502 and the lower connecting plate 503 relative to the main body cylinder 1 and the barrier cover 2 respectively. The threaded rod 504 is movably connected with the surface of the support plate 501 and is perpendicular to the inner wall of the support plate 501. The threaded cylinder 505 is threadedly connected with the outer surface of the threaded rod 504. The top of the threaded rod 504 is fixedly connected with a handle. The support rod 506 is fixedly connected with the threaded cylinder 505 and the lower connecting plate 503 at both ends. The sliding rail 507 is fixedly connected with the inner wall of the support plate 501 and is parallel to the threaded rod 504. The sliding block 508 is located in the inner wall of the sliding rail 507 and is slidably connected with the inner wall of the sliding rail 507. The connecting rod 509 is fixedly connected with the outer surface of the sliding block 508 and the threaded cylinder 505 at both ends.

[0042] When disassembling, the upper connecting plate 502 and the lower connecting plate 503 are disassembled by bolts, and then the upper connecting plate 502 and the lower connecting plate 503 are separated from the main body cylinder 1 and the barrier cover 2 respectively, so that the barrier cover 2 can be pulled out of the main body cylinder 1. Since the main body cylinder 1 is composed of two half cylinders, the barrier cover 2 is removed, so that the two half cylinders can be separated, thereby facilitating the cleaning of the inner wall of the main body cylinder 1 and the floating ball 3.

[0043] When there is a requirement for different depths of accumulated water, the threaded rod 504 is rotated, the threaded rod 504 is threadedly connected with the threaded cylinder 505, the threaded cylinder 505 drives the lower connecting plate 503 to move up and down through the support rod 506, thereby changing the height of the micro switch 4 relative to the ground and indirectly changing the monitoring standard of the depth of the accumulated water.

[0044] The working principle of the above embodiment is as follows:

[0045] The water enters the inside of the main cylinder 1 through the water inlet hole of the main cylinder 1, and when the water level rises, the floating ball body 303 and the floating ring 305 are driven to move upwards until the contact plate 306 touches the light touch switch 4 on the main cylinder 1, the light touch switch 4 is electrically connected with the alarm, so that the alarm can be performed. When disassembling, the upper connecting plate 502 and the lower connecting plate 503 are disassembled through bolts, and then the upper connecting plate 502 and the lower connecting plate 503 are separated from the main cylinder 1 and the blocking cover 2 respectively, so that the blocking cover 2 can be pulled out of the main cylinder 1. Since the main cylinder 1 is composed of two half cylinders, the blocking cover 2 is released, so that the two half cylinders can be separated, thereby facilitating the cleaning of the inner wall of the main cylinder 1 and the floating ball member 3.
