Abstract
A water deficiency protection pump used for water cluster and fountain comprises a pump (1) and a water level detecting switch (2) which is connected in series with the pump (1). The water level detecting switch is positioned on the periphery of the pump and is connected in series with the pump. When the pool or cluster is deficient in water, the pump power is cut off automatically, preventing the pump from operating in the state of water deficiency and burning out. The pump and the water level detecting switch can be manufactured separately and independently and then installed together, with simple structure, convenient installation and low cost of production. The water level detecting switch has simple structure, low cost and reliable operation.
Description
1, technical field:
The utility model relates to the excessive low water level protection water pump that a kind of water bunch and fountain are used.
2, background technique:
The tradition water pump does not generally have protective gear, adds water or certain reason there is not water in pond or water bunch when the user goes on business or forgets, water pump can not stopped transport row and burnt, and damages equipment.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the excessive low water level protection water pump that a kind of water bunch and fountain are used.
The utility model is achieved by the following technical solution:
The excessive low water level protection water pump that a kind of water bunch and fountain are used comprises water pump, and it also comprises a water-level detecting switch in addition, and water pump and water-level detecting switch are cascaded.
Above-mentioned described water pump and water-level detecting switch can place the closed cavity the inside of a housing, and the probe of the detection water level of water-level detecting switch stretches out housing.
Above-mentioned described water pump and water-level detecting switch are installed in separate big shell and little shell respectively, be extended with two probes up and down on the shell of water-level detecting switch, little shell is installed in the side of big shell, and the lead of water-level detecting switch stretches out the water pump that is connected big housings from little shell.
The probe height that is positioned at the top of above-mentioned described water-level detecting switch is more than or equal to the highest point of water pump water inlet.
Above-mentioned described water-level detecting switch comprises water level sensor circuit, comparison circuit, drive circuit and rectification circuit, the input end of rectification circuit connects low-voltage alternating current power supply, the output terminal of rectification circuit connects the comparison circuit input end, the water level sensor circuit pick up water level signal, the output terminal of water level sensor circuit is connected to the input end of comparison circuit, and the output terminal of comparison circuit connects the input end of drive circuit, the on-off of drive circuit control of pump power supply circuits.
The utility model compared with prior art has following advantage: 1) periphery of water pump comprises a water-level detecting switch, water pump and water-level detecting switch are cascaded, when in pond or the water bunch during lack of water, cut off pump power automatically, prevent that water pump from not stopping transport then burn out under exsiccosis; 2) water pump can separate independent manufacturing with the water-level detecting switch, is installed together then, and simple in structure, easy for installation, cost is lower; 3) the water-level detecting construction of switch is simple, and cost is lower, reliable operation.
