Description

Technical Field

[0001] The utility model relates to the technical field of water tower water level control, in particular to a full-automatic water tower water level controller. Background Art

[0002] In the prior art, the water level of a pool or water tower is controlled by a ball valve. This traditional water level controller has the following shortcomings: First, it is difficult to work when the water pressure is insufficient; second, this control method is only suitable for the control of water supply from water pipes, but it is difficult to control the water level of deep wells and ponds; third, the float control can only be one ball per pool, and centralized control cannot be implemented. In addition, this method has very high requirements on the sealing of the float. Once cracks or corrosion holes occur, the water level control will completely fail, and its reliability is relatively poor.

[0003] A water tower water level controller refers to an instrument used on a water tower for automatic water level control. Most of them are fully automatic and can be unattended. They can automatically replenish water when there is a water shortage and automatically stop the water supply when the water is full.

[0004] At present, water tower water level controllers are mainly divided into mechanical and electromagnetic types. Mechanical ones, such as lever-type float inlet valves, are composed of float devices, check valves, tees, external threads and other accessories. Therefore, the structure is complex, the installation is time-consuming and material-intensive, and the water tower is prone to overflow during use, resulting in waste of resources. For electromagnetic ones, such as solenoid valves, it is necessary to control the water supply pump and the solenoid valve at the same time during use. This is not only troublesome, but also easy to cause damage to the water supply pump if the solenoid valve fails. Therefore, a fully automatic water tower water level controller is provided to solve the above problems. Utility Model Content

The first sensor 16 is arranged at the bottom end of the sleeve 15, and the second sensor 17 is arranged on one side of the upper end of the sleeve 15. A fixing head 18 is arranged at the bottom end of the sleeve 15. The sleeve 15 is connected with a wire inside, and the wires are respectively connected to the first sensor 16 and the second sensor 17. The sleeve 15 is made of stainless steel. When the sensing rod is installed on the water tower, it is only necessary to remove the water tower cover and drill a hole in the cover with a drill or a hole opener, and the sensing rod is installed on the cover through the fixing head 18, and kept at 90° to the cover surface.

[0023] Combination Figure 2 and Figure 3 As shown, the controller housing includes a base 1 and an upper cover 2, and the controller mainboard 3 is fixedly installed between the base 1 and the upper cover 2 by screws.
