Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to a water supply structure. Background Art

[0002] During the fermentation process of organic fertilizer, it is often necessary to maintain a certain humidity of the material. For this reason, moisture is often added by spraying water on the surface of the compost during the fermentation process. Generally, water is sprayed manually by carrying a sprayer on the back. The spraying process of the sprayer increases the labor intensity of the relevant staff to a certain extent.

[0003] Of course, water can also be moved to the corresponding material pile through an existing vehicle equipped with a water tank. During the water spraying process, a pump is needed to pump the water out of the water tank, but during the water tank filling process, another pump is needed to pump the water into the water tank. Since most water pumps are centrifugal pumps, and centrifugal pumps usually cannot be reversed, the angle and shape of the impeller blades are different when the centrifugal pump is reversed, which will cause the liquid flow direction to change, reducing or stopping the pump's delivery capacity, and the forward and reverse rotation of the centrifugal pump requires different mechanical closures, otherwise it will cause liquid leakage. Therefore, most existing vehicles are equipped with a drainage pump and a suction pump, and two water pumps are required on board. In addition, the pipe connection needs to be manually replaced during the pumping and drainage process, resulting in increased usage and driving costs.

[0004] Therefore, it is necessary to design a vehicle-mounted water tank structure to achieve water tank drainage and water tank filling through a single water pump to reduce costs. Utility Model Content

[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a water supply structure.

[0006] The utility model proposes a water supply structure, comprising a water tank body, a water pump and a combined pipeline installed on a vehicle body, the water tank body is connected to the water pump through the combined pipeline, the water pump is connected to a water outlet pipe through the combined pipeline, the combined pipeline has a drainage pipeline and a water injection pipeline, and the pipelines are switched through multiple valves, and it should be noted that the water outlet pipeline can be connected to a sprinkler to achieve uniform watering of the surface of an organic fertilizer material pile.

[0007] As a further optimized solution of the utility model, the combined pipeline includes a first pipeline, a second pipeline, a third pipeline, and a fourth pipeline. One end of the first pipeline is installed on the water inlet end of the water pump, and the other end of the first pipeline is connected to the water tank body. One end of the second pipeline is installed on the water outlet end of the water pump, and the other end of the second pipeline is connected to the water outlet pipe. The third pipeline is installed on the first pipeline, and both ends of the fourth pipeline are respectively connected to the first pipeline and the second pipeline, and valves are installed on the first pipeline, the second pipeline, the third pipeline, and the fourth pipeline.

[0008] As a further optimized solution of the utility model, a first valve is installed on the first pipeline, a second valve is installed on the second pipeline, a third valve is installed on the third pipeline, and a fourth valve is installed on the fourth pipeline. The first valve is arranged between the third pipeline and the fourth pipeline, and the second valve is arranged above the interface between the fourth pipeline and the second pipeline.

[0009] As a further optimized solution of the utility model, the first valve is arranged below the interface between the fourth pipeline and the first pipeline.

[0010] As a further optimized solution of the utility model, when the third valve and the fourth valve are in a closed state, the first valve and the second valve are in an open state, the first pipeline, the water pump, and the second pipeline are interconnected to form a drainage pipeline.

[0011] As a further optimized solution of the utility model, when the third valve and the fourth valve are in an open state, the first valve and the second valve are in a closed state, the first pipeline, the third pipeline, the water pump, the second pipeline, and the fourth pipeline are interconnected to form a water injection pipeline.

[0012] The water supply structure proposed by the utility model has the following beneficial effects:

[0013] The utility model improves the water inlet and outlet pipelines of the water tank, closes the third pipeline and the fourth valve, opens the first valve and the second valve, so that the two ends of the first pipeline are respectively connected to the water tank body and the water pump, and the two ends of the second pipeline are respectively connected to the water pump and the water outlet pipe, so that the water in the water tank body is supplied to the water outlet pipe through the water pump. When it is necessary to fill water into the water tank body, it is only necessary to close the first valve and the second valve, open the third pipeline and the fourth valve, connect the free end of the third pipeline to the water source, and pump water through the water pump. The water passes through the third pipeline, the lower end of the first pipeline, the water pump, the lower end of the second pipeline, the fourth pipeline in sequence, and is finally injected into the water tank body from the upper end of the first pipeline to realize the water filling of the water tank body. The overall structure is simple and the operation is convenient. By improving the pipeline, only one vehicle-mounted water pump is needed to realize the drainage and water filling of the water tank, and there is no need to add a water pump, which is beneficial to reducing the use cost and driving cost, and can also improve the utilization rate of the vehicle-mounted space, which is beneficial to reducing the volume of the whole vehicle and facilitating shuttle driving. It has broad market prospects and is conducive to market promotion.
