Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology, and in particular relates to a water storage device for agricultural irrigation. Background Technology

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm. It is the most effective water-saving irrigation method, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. It can also be combined with fertilization to increase fertilizer efficiency by more than double. It is suitable for irrigation of fruit trees, vegetables, cash crops, and greenhouses. It can also be used for field crop irrigation in arid and water-scarce areas. Currently, temporary drip irrigation devices cannot store water or collect and utilize rainwater. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Please see Figure 1 As shown, this utility model is a water storage device for agricultural irrigation, comprising two pre-buried pits, A40 and B, on the ground. Pre-buried pit B can be set in agricultural crop planting areas, while pre-buried pit A40 can be set in both agricultural crop planting areas and non-agricultural crop planting areas. A water storage tank 2 is supported by a support frame in pre-buried pit A40. The bottom end of the water storage tank 2 is connected to a drain pipe 21, and a solenoid valve is connected to the drain pipe 21. The outlet end of the drain pipe 21 is connected to a water supply pipeline. A water supply tank connected to the water supply pipeline is installed in pre-buried pit B. A water pump is installed in the water supply tank and connected to the irrigation water pipe. After installation, the bottom side of the water storage tank 2 is higher than the top side of the water supply tank. Thus, when the solenoid valve is opened, it is convenient to control the irrigation water in the water storage tank 2 to flow through the drain pipe 21 and the water supply pipeline into the water supply tank, and then the irrigation water is pumped out by the water pump in the water supply tank to complete the irrigation.

[0023] To facilitate rainwater collection, such as... Figure 3-4 A water collection trough 24 is connected to the top of the water storage tank 2; for easy installation, a flange 20 is installed on the water storage tank 2, and a top cover 22 is bolted to the flange 20. At least three support pipes 23 are connected to the top of the top cover 22, and the support pipes 23 are connected to the bottom side of the water collection trough 24; and the support frame includes a support ring 1 supported on the bottom side of the water storage tank 2, and the bottom side of the support ring 1 is connected to the support leg 11.

[0024] In order to filter rainwater and prevent sand, leaves, weeds and other debris from flowing into the water storage tank 2, a filter assembly is installed in the water collection tank 24.

[0025] To facilitate filtration, filter cloth A is laid on the bottom side of the water collection tank 24, a sponge block is laid on top of filter cloth A, filter cloth B is laid on top of the sponge block, and a wire mesh is laid on top of the wire mesh.

[0026] In order to facilitate irrigation control during use, in a possible extended technical solution, level sensors A and B are respectively installed in the water supply tank and the water storage tank 2. Both level sensors A and B are connected to a controller, which is connected to the water pump and the solenoid valve. When in use, the solenoid valve is first opened until the level sensor A in the water supply tank detects that the liquid level meets the set value. At this time, the water pump is controlled to start irrigation. When it rains, when the level sensor B detects that the liquid level in the water storage tank 2 is too high, the solenoid valve is opened to fill the water supply tank with water until the level sensor A detects that the liquid level has reached the high point. At this time, the solenoid valve is controlled to close. This operation ensures that water can be stored to the maximum extent possible during rain.

[0027] Based on the above setup, in order to better collect rainwater during rain, a cement-cast edge 4 is provided around the top opening of the pre-buried pit A40; a ring 3 is provided at the top of the edge 4, and a protrusion 32 is provided on the inner side wall of the ring 3 to be inserted into the top cover 22; thus, after installation, rainwater flowing on the ground during rain will overflow the ring 3 and enter the water collection tank 24 for collection.

[0028] To facilitate the installation of the ring body 3 and to allow rainwater to overflow the ring body 3 and enter the water collection tank 24, a post 31 is provided on the bottom side of the ring body 3, and a hole 42 that matches the post 31 is provided on the top surface of the rim 4; a downwardly recessed stepped surface 41 is provided on the top inner ring of the rim 4, and the hole 42 is opened on the stepped surface 41; after installation, the upper surface of the ring body 3 is lower than the top surface of the rim 4.
