However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0013] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0015] like Figure 1 As shown, Figure 1This is a schematic diagram of the structural principle of an automatic water replenishment and cleaning device in the present invention applied to a cooling tower; an automatic water replenishment and cleaning device applied to a cooling tower, comprising a water replenishment float valve 10, a cleaning pump 20, a water replenishment and cleaning water tank (not shown in the figure to display the cleaning pump), and a water spraying mechanism 40, the water inlet of the water replenishment float valve 10 is connected to an external water source through a pipe, the water outlet of the water replenishment float valve 10 is connected to the water replenishment and cleaning water tank through a pipe, the water inlet of the cleaning pump 20 is connected to the water replenishment and cleaning water tank through a pipe, and the water outlet of the cleaning pump 20 is connected to the water spraying mechanism 40 through a pipe, the water spraying mechanism 40 comprises a water supply pipe 41 in the shape of a "return" character, a "sun" character, or a "eye" character, and a plurality of fan-shaped nozzles 42, the water supply pipe 41 is arranged on one side or both sides of the filler in the cooling tower, and the fan-shaped nozzles 42 are evenly spaced on the water supply pipe.

[0016] The device of the present invention is applied to a cooling tower, and provides water replenishment and cleaning functions for the cooling tower, so it combines the water replenishment and cleaning mechanisms together, and controls the water replenishment by inserting a float water replenishment valve in the water replenishment pipe. One end of the float water replenishment valve is connected to an external water source, and the other end is connected to a water replenishment and cleaning water tank. The external water source is usually clean water with a low impurity concentration, which is different from the water in the water storage tank of the cooling tower, which has certain dirt. A water tank is specially provided here to store the water for replenishment, and is also used as cleaning water. The controller determines the opening of the float water replenishment valve and the cleaning pump according to the water level of the cooling water tank of the cooling tower. The cleaning pump directly pumps the water in the water replenishment and cleaning water tank to the water spraying mechanism to spray the filling 50 in the cooling tower, thereby completing the cleaning of the cooling tower filling 50. Here, the controller of the cooling tower can control the opening of the float water supply valve and the cleaning pump with a certain time difference. For example, the float water supply valve is opened first, and after a certain amount of water is added, the cleaning pump starts to pump water. The controller controls the float water supply valve according to the water level of the cooling water tank of the cooling tower.

[0017] In order to make the water replenishment and cleaning process intelligently controlled and have multiple optional control modes, it is preferably further included a flow switch 30, the two ends of which are connected to the water replenishment float valve 10 and the water replenishment and cleaning water tank through pipes, and the flow switch 30 is electrically connected to the controller in the cooling tower.

[0018] A flow switch is set to determine whether to replenish water. When replenishing water, the flow switch micro-switches, generating a signal that is transmitted to the controller, which controls the cleaning pump to start working. In this way, replenishing water and cleaning are carried out simultaneously, eliminating the need to control the liquid level in the replenishing and cleaning water tank. Combined with the above-mentioned control method of opening the float water replenishment valve according to the water level of the cooling tower, and the control method of starting the cleaning pump and the float water replenishment valve at a timed interval, a dual control method can be achieved, which can avoid damage to the flow switch and will not affect the operation of the cleaning pump.

[0019] In order to save space in the cooling tower, preferably, the cleaning pump is a submersible pump, and the cleaning pump is arranged in the water in the water replenishment cleaning water tank.

[0020] The cleaning pump is a submersible pump that can be submerged in water. It can be placed in the water replenishment and cleaning tank, without taking up unnecessary cooling space, thus saving space in the entire cooling tower.

[0021] Compared with the existing technology, the beneficial effects of the present invention are: utilizing the water replenishment demand in the cooling tower, a float water replenishment valve is set in the water replenishment pipeline to control whether water replenishment is performed; a water replenishment and cleaning water tank is set to store the replenishment water separately, and the cleaning water is made into a purer water source with diluted impurity concentration; by selecting the cleaning pump as a submersible pump, the entire cooling tower can be made more space-saving; by setting a flow switch and cooperating with a controller, the cleaning pump can start the cleaning mode according to the linkage of the water replenishment flow switch; by designing the delivery pipeline into various standard shapes, the cleaning coverage range is wide, and by further designing the nozzle into a fan-shaped spray, the water spray pressure is greater, the spray range is wider, and the cleaning is cleaner.

[0022] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
