Description

Technical Field

[0001] The utility model relates to the technical field of high liquid level automatic regulation, in particular to a high liquid level automatic regulation device. Background Art

[0002] The high liquid level automatic regulating device is an important part in domestic water supply and manufacturing. It is a device used to monitor and control the water level of the pool. It monitors the water level of the pool in real time through sensors, and automatically controls the switch of the water pump or valve according to the set water level range to keep the water level of the pool within the appropriate range, effectively improving the utilization efficiency of water resources, reducing the workload of manual operations, and also improving the safety and stability of the pool.

[0003] In the prior art, the liquid level control device of the high liquid level automatic regulating device usually uses a connecting rod liquid level float switch. The working principle of the connecting rod float switch is mainly based on the up and down movement of the float to control the opening and closing of the switch contacts. When the liquid level rises, the float rises accordingly, and its buoyancy increases, which will push the float on the connecting rod to move upward, thereby driving the switch contacts to close and connect the circuit. On the contrary, when the liquid level decreases, the float drops, its buoyancy decreases, and the float on the connecting rod moves downward accordingly, pushing the switch contacts to open and disconnecting the circuit. However, when adjusting the movement position of the float, it is usually necessary to use a screwdriver to loosen the screws of the stop ring to adjust the position. After adjusting the appropriate position, tighten the screws of the stop ring with a screwdriver to fix it. The operation process is relatively cumbersome. At the same time, the exposed screws are easily corroded in the liquid, which will also cause trouble for the subsequent adjustment of the stop ring position. Therefore, a high liquid level automatic regulating device is needed to meet people's needs. Utility Model Content

The plurality of special-shaped shrink blocks 8 are made of elastic alloy materials. The elastic alloy materials have good elastic properties and are non-magnetic. A limit block 9 is installed on the upper part of the outer wall of the plurality of special-shaped shrink blocks 8. A transmission assembly is arranged on the left side of the limit block 9. The transmission assembly includes a rack plate 12. The right side surface of the rack plate 12 is connected to the left side surface of the limit block 9. The first gear 13 is meshed and installed on one side of the outer wall of the rack plate 12, the second gear 14 is meshed and installed on one side of the outer wall of the first gear 13, and the worm rod 15 is meshed and installed on one side of the outer wall of the second gear 14.

The second gear 14 and the first gear 13 are both rotated by the first rotating shaft 6. The lower surface of the support block 21 is fixed to the lower side of the inner wall of the stop ring 3, and the upper surfaces of the two limit blocks 9 are both installed with Two springs 11, the other ends of the multiple springs 11 are fixed to the upper part of the inner wall of the corresponding stop ring 3. The elastic force of the spring 11 can make the limit block 9 and the special-shaped shrink block 8 closer, and at the same time, it plays a buffering role to a certain extent under the action of external force, and protects the stop ring 3. Two first sealing grooves 17 are provided inside the two stop rings 3, and the inner walls of the multiple first sealing grooves 17 are installed with first sealing rings 18.
