[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0019] See also Figure 1-2 , a liquid level control device for a water tank in a fire pump room comprises a mounting platform 1, a support frame 2 is fixedly mounted on the side of the mounting platform 1, a sliding column 3 is fixedly mounted on one end of the support frame 2 away from the mounting platform 1, grooves are provided on both sides of the sliding column 3, and the grooves are consistent with the protrusions fixedly mounted on the side of the float 5, so that the float 5 will not be separated from the sliding column 3 when sliding along the sliding column 3, a water inlet pipe 12 is fixedly mounted on the lower part of the sliding column 3, a water inlet bin 14 is fixedly mounted on the upper part of the inner wall of the water inlet pipe 12, a water inlet port 13 is provided on the lower side of the water inlet bin 14, the water inlet port 13 is contacted with a piston 11 and the inner diameter of the water inlet port 13 is consistent with the outer diameter of the piston 11, the piston 11 blocks the water inlet port 13, at this time, the water pipe in the water inlet pipe 12 no longer flows, a water outlet pipe 15 is provided on the side of the water inlet bin 14, the sliding column 3 is slidably connected with the float 5, a fixing member 6 is fixedly mounted on the lower part of the side of the float 5, the fixing member 6 is threadedly connected with a threaded rod 7, the thread The top of the rod 7 is fixedly installed with a circular protrusion, and the diameter of the circular protrusion is larger than the width of the fixing piece 6. The setting of the protrusion prevents the threaded rod 7 from being separated from the fixing piece 6, and the protrusion can make it more convenient for the operator to rotate. The lower part of the threaded rod 7 is rotatably connected to a swivel seat 8, and the swivel seat 8 is rotatably connected to an adjusting rod 9. The other end of the adjusting rod 9 is rotatably connected to one end of a swivel rod 10, and the swivel rod 10 is rotatably connected to the sliding column 3. The other end of the swivel rod 10 is rotatably and slidably connected to a piston 11, and the upper side of the water inlet pipe 12 is slidably connected to the piston 11, and the upper part of the piston 11 is rotatably connected to the swivel rod 10. The utility model drives one end of the swivel rod 10 to rotate through the float 5, so that the other end of the swivel rod 10 drives the piston 11 to move upward or downward, so that water inlet is stopped when the liquid level is too high, and water inlet is automatically started when the liquid level is too low, so as to meet the different requirements of the fire pump room for high and low liquid levels, so that the water volume in the water tank is maintained in a certain range.

[0020] When in use, the liquid level in the water pool of the fire pump room rises, and the rising liquid level drives the float 5 to move vertically upward along the sliding column 3. The float 5 drives the threaded rod 7 to move vertically upward through the fixing piece 6. When the threaded rod 7 moves vertically upward, it drives the adjusting rod 9 to rotate. The adjusting rod 9 drives one end of the rotating rod 10 to rotate counterclockwise, so that the other end of the rotating rod 10 drives the piston 11 to move downward. The piston 11 moves vertically downward to block the water inlet 13, so that the air pressure on the upper part of the water inlet pipe 12 increases, so that the water in the water inlet pipe 12 no longer flows out, and the water stops flowing out. After a period of time, the liquid level in the water tank of the fire pump room drops, and the float 5 moves vertically downward along the sliding column 3, driving the threaded rod 7 to move vertically downward. The threaded rod 7 drives one end of the rotating rod 10 to rotate clockwise, and the other end of the rotating rod 10 drives the piston 11 to move vertically upward and away from the water inlet 13, thereby reducing the air pressure in the water inlet pipe 12. At this time, the water in the water inlet pipe 12 flows out through the water outlet pipe 15, so that the liquid level returns to normal, and the position of the float 5 can be adjusted by rotating the threaded rod 7. The closer the float 5 is to the top of the threaded rod 7, the higher the controlled liquid level. Embodiment 2

At this time, the buzzer 18 produces a loud alarm sound, and a circular protrusion is fixedly installed on the upper part of the float 5, and the protrusion is consistent with the groove on the lower side of the baffle 4. The setting of the spring can provide downward resistance to the movable block 16 to prevent the movable block 16 from accidentally touching the trigger switch 17. The utility model contacts the trigger switch 17 through the movable block 16 and drives the trigger switch 17 to turn on, thereby turning on the buzzer 18. At this time, the water level reaches the critical point, and the buzzer 18 produces a loud alarm sound to remind the staff to pump out the water in the pool.

[0022] During use, on the basis of Example 1, when the float 5 slides vertically upward along the sliding column 3 to the baffle 4, the circular boss above the float 5 fits with the groove at the bottom of the baffle 4, and the movable block 16 is moved vertically upward under the drive of the float 5. The movable block 16 is moved vertically upward in the groove, so that the spring on the movable block 16 contracts, and the movable block 16 contacts the trigger switch 17 and drives the trigger switch 17 to turn on, thereby turning on the buzzer 18. At this time, the water level reaches the critical point, and the buzzer 18 produces a loud alarm sound to remind the staff to pump out the water in the pool.
