Abstract
The utility model relates to a water lack protection system for a water tank. The water lack protection system for a water tank comprises a cylinder body bracket, a circulating water pump, a circulating water tank, a water outlet pipe and a cylinder body, wherein the water outlet pipe is connected with the circulating water tank and the cylinder body, water is sucked into the cylinder body from the circulating water tank through the circulating water pump, and the cylinder body is provided with a backflow pipe at a part with a certain height; and the water lack protection system also comprises a water flow switch and a control circuit, the water flow switch is arranged on the water outlet pipe, and the control circuit is connected with the circulating water pump and used for providing a power supply for the circulating water pump. According to the water lack protection system for the water tank, due to the water flow switch arranged on the water outlet pipe, water flows in the water outlet pipe can be timely judged so as to guarantee that the circulating water pump is stopped working when the circulating water tank is lack of water and prevent the water pump from pumping without water, therefore, the water pump is prevented from being damaged, and accidents are avoided.
Description
Technical field
The utility model relates to a kind of water tank lacks water protection system.
Background technology
Water tank all has in family, restaurant, star hotel and other public place widely and uses as culturing purposes.Because water body has the influence of arriving very much to the animal and plant of culturing therein in the water tank, generally all needs water tank to be equipped with water circulation system.The structure of common water tank is as shown in Figure 1 in the market; Form by cylinder rack 1, water circulating pump 2, cyclic water tank 3, outlet pipe 4, cylinder body 5; Water circulating pump is used for realizing the water circulation of water tank, after water circulating pump 2 energising, the water of 3 li of cyclic water tanks is discharged into cylinder body 5 through outlet pipe 4; Turn back to cyclic water tank 3 through return pipe 6 again, so circulation is to reach the water circulation purpose of water tank.But, cause the interior water level of cylinder body to change because in the actual application, the animals and plants of culturing in water tank may increase or reduce; The water tank of for example using as fish jar, fish often is placed into or pulls out, and the water level in the cylinder body 5 also changes thereupon; When fish jar normally uses, as the water level increase of putting into fish rear-bank rotor housing 5, increase more for a long time; Water in the cylinder body 5 can overflow, and gets into cyclic water tank 3 through return duct 6; But after fish was pulled out fish jar, water level reduced in the cylinder body 5, and water circulating pump sucks cylinder body with water, does not but have water to turn back to cyclic water tank 3 from return duct 6, particularly worked as water level and reduced more for a long time, just possibly cause lacks of water in the cyclic water tank 3.At present, address this problem main dependence manual work and see and examine, when finding cyclic water tank 3 lacks of water through manual moisturizing.This situation once operative employee's carelessness will cause the water pump dry tap, causes burning out water pump, and serious also leaky can occur.
The utility model content
The purpose of the utility model provides a kind of water tank lacks water protection system, can when the cyclic water tank lack of water, prevent the water pump dry tap.
The purpose of the utility model is achieved in that
A kind of water tank lacks water protection system comprises cylinder rack, water circulating pump, cyclic water tank, outlet pipe and cylinder body, and outlet pipe connects cyclic water tank and cylinder body; Through water circulating pump water is sucked cylinder body from cyclic water tank; Said cylinder body is provided with return duct at the certain altitude place, also comprises a water flow switch and a control circuit, and said water flow switch is located on the said outlet pipe; Said control circuit is connected with said water circulating pump, is used for to water circulating pump power supply being provided.
When the water pump operate as normal, water flow switch is opened, and control circuit continues the power supply of water pump; When the cyclic water tank lack of water, water flow switch is closed, and control circuit breaks off the power supply of water pump.
The utility model is owing to adopted technique scheme; Compared with prior art have following beneficial effect: the utility model water tank lacks water protection system, through on outlet pipe, installing a water flow switch, can in time judge the water outlet in-pipe flow; Water circulating pump quits work when guaranteeing the cyclic water tank lack of water; Prevent the water pump dry tap, destroy water pump, avoid accident to take place.
Description of drawings
Through following embodiments of the invention and description taken together with the accompanying drawings, other advantage of the present invention and characteristic are shown, this embodiment provides with the form of instance, but is not limited to this, wherein:
Fig. 1 is the cisten mechanism sketch map of prior art;
Fig. 2 is the structural representation of the utility model water tank lacks water protection system.
Embodiment
As shown in Figure 2; A kind of water tank lacks water protection system comprises cylinder rack 1, water circulating pump 2, cyclic water tank 3, outlet pipe 4 and cylinder body 5, and outlet pipe 4 connects cyclic water tank 3 and cylinder body 5; Through water circulating pump 2 water is sucked cylinder body 5 from cyclic water tank 3, shown in arrow among the figure.Cylinder body 5 is provided with return duct 6 at the certain altitude place, also comprises a water flow switch 7 and a control circuit 8, and water flow switch 7 is located on the outlet pipe 4, and control circuit 8 is connected with water circulating pump 2, is used for to water circulating pump 2 power supply being provided.
When water circulating pump 2 operate as normal, water flow switch 7 is opened, and control circuit 8 continues the power supply of water circulating pump 2; When cyclic water tank 3 lacks of water, water flow switch 7 is closed, and control circuit 8 breaks off the power supply of water circulating pump 2, prevents that water circulating pump 2 from dry tap taking place.
