Description

Technical Field

[0001] The utility model relates to a rainwater collection and drainage technology for an aquaculture greenhouse. Background Art

[0002] In the field of aquaculture in the southern region, earthen pond winter sheds have the characteristics of low investment cost, large single shed area, and convenient management. They provide good temperature conditions for aquatic products in winter and are deeply loved by farmers. However, the existing earthen pond winter shed technology does not have rainwater collection and drainage technology, which causes rainwater to be directly discharged into the aquaculture water body. This is very likely to cause aquaculture problems such as algae overturning in the aquaculture water body, outbreaks of fish saprolegniasis, shrimp stress and enteritis, and the losses caused every year are countless. Therefore, there is an urgent need for a rainwater collection and drainage device suitable for earthen pond winter sheds, and this technology must have the characteristics of low cost, simple materials, and no impact on aquaculture and harvesting. Utility Model Content

[0003] The utility model aims to provide a rainwater collection and drainage device for an earth pond greenhouse, and to provide a solution to the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rainwater collection and drainage device for an earth pond greenhouse, which includes a floor drain and its matching hose, a main water collecting pipe, a water collecting tank flange, a water collecting tank, a submersible pump, an external discharge hose, a rain sensor switch and probe, a water collecting tank liquid level switch and probe, a rain sensor funnel, a greenhouse water retaining pipe and its control circuit.

[0005] The above-mentioned earth pond greenhouse rainwater collection and drainage device, the main water collecting pipe is connected to the greenhouse film through a floor drain and its hose, the main water collecting pipe is connected to the water collecting tank through the water collecting tank flange, the rain sensing funnel is connected to the funnel above it and its hose and fixed to the water collecting tank, the water intercepting pipe is installed between the film and the steel wire at the bottom of the greenhouse to intercept rainwater and guide it into the floor drain.

[0006] The control circuit of the above-mentioned earth pond greenhouse rainwater collection and drainage device is composed of a rain sensor switch and its probe, a water collection tank liquid level switch, a submersible pump relay switch and its delay switch. The delay switch can be selected to reduce the start and stop frequency of the submersible pump and increase its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0010] See also Figure 1 The utility model provides an embodiment: a rainwater collection and drainage device for an earth pond greenhouse includes a floor drain and its matching hose, a main water collecting pipe, a water collecting tank flange, a water collecting tank, a submersible pump, an external discharge hose, a rain sensing switch and probe, a water collecting tank liquid level switch and probe, a rain sensing funnel, a greenhouse water blocking pipe and its control circuit.

[0011] The principle is as follows: when rainwater is intercepted by the water interception pipe 11 and enters the floor drain and its hose 1, the rain sensor switch is activated. As the rainwater continues to collect in the main water collection pipe 9 and the water collection tank 7, the water level in the water collection tank 7 continues to rise, the liquid level switch is activated, the submersible pump relay is started in the same way, the submersible pump 6 is powered on, and the rainwater is discharged through the external hose. When the water level in the water collection tank 7 drops below the liquid level probe, the liquid level switch is powered off, the delay switch works, and the water pump will be delayed to shut down. When the rain stops, the rain sensor switch is closed, and the water pump is powered off and shut down. There is an open rainwater outlet on the top of the water collection tank to prevent the rainfall from exceeding the water pump flow.

[0012] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
