With the development of the soil greenhouse irrigation technology, the traditional soil greenhouse irrigation technology does not meet the requirements of the current greenhouse on energy-saving and efficient irrigation, and the current traditional soil irrigation modes of sprinkling irrigation, flood irrigation, burette and the like in the greenhouse have the defects of different degrees, such as high cost, high energy consumption, inconvenient maintenance and the like. At present, the greenhouse needs a novel irrigation technology to make up for the defects of the existing greenhouse irrigation, and is also an important direction and challenge for the development of the soil greenhouse.

In a greenhouse with soil, large-area irrigation is not very convenient due to space limitations. The sprinkling irrigation represented by high-humidity micro-spraying and mist spraying needs to be at the cost of motor energy consumption, equipment is needed in the greenhouse, a dropper needs accurate control and a large amount of equipment with higher cost, the utilization rate of water for flood irrigation is low, a large amount of water mist is formed in the greenhouse, the temperature inside the greenhouse is rapidly increased, the tidal irrigation has high requirements on early-stage construction of the greenhouse, and the tidal irrigation is difficult to use in the existing greenhouse.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and it will be apparent to those skilled in the art that various changes may be made without departing from the spirit and scope of the utility model as defined and defined in the appended claims, and all matters produced by the utility model using the inventive concept are protected.

In the first embodiment, as shown in fig. 1, the soil irrigation system for the water hammer greenhouse space provided by the utility model comprises a water hammer pump 2, wherein the water hammer pump 2 comprises a first pipeline 201 and a second pipeline 202, and the water hammer pump 2 is communicated with an external water source through a water inlet pipe 1; the water hammer pump 2 is respectively communicated with a ceiling sprinkler irrigation device 5 and a ground flood irrigation device 6 through a first water outlet pipe 3 and a second water outlet pipe 4.

The hydraulic ram specifically structure does:

the first pipeline 201 is vertically communicated with the second pipeline 202 through a first tee water pipe 212; the first pipeline 201 is communicated with the first water outlet pipe 3 through an elbow water pipe 214; the second pipeline 202 is communicated with a second water outlet pipe 4 through a second three-way water pipe 213; the second conduit 202 communicates with the buffer air chamber 203 through a third conduit through head 208.

The first water outlet pipe 3 is provided with a first check valve 204 for allowing water to pass upward, and the second pipeline 202 is provided with a second check valve 205 for allowing water to pass downward.

The first check valve 204 and the second check valve 205 are opened and closed repeatedly and alternately by controlling the water flow direction and under the action of the water flow, so that a water hammer effect is generated in the water hammer pump, the water flow of the water inlet pipe 1 is enabled to flow out from the first water outlet pipe 3 and the second water outlet pipe 4, and meanwhile, unnecessary water flow backflow is reduced.

Meanwhile, the pressure condition inside the hydraulic ram can be observed through the transparent buffer air chamber 203, and the pipeline damage caused by the hydraulic ram effect is relieved.

The water flow from the first water outlet pipe 3 and the second water outlet pipe 4 respectively enters the ground flood irrigation device 6 and the ceiling sprinkler irrigation device 5, so that the greenhouse soil is irrigated in an all-around manner.

The working principle of the water hammer spatial irrigation system with the soil greenhouse is as follows:

the water entering the ram 2 from the inlet pipe 1 will hit the first check valve 204 and the second check valve 205, and since the direction of the first check valve 204 prevents the water source from passing through, and the direction of the second check valve 205 allows the water to pass through, the water will accumulate in the upper pipe above the second check valve in the second pipe after passing through the second check valve 205 whenever the water rises to the level of the first check valve 204 and the second check valve 205.

After the water pressure in the upper pipe above the second check valve in the second pipe 202 rises, the water flow above the second check valve 205 forms a return impact force, so that the second check valve 205 is closed briefly, the first check valve 204 is opened, and the water flow will gush out from the first check valve 204; after the water flow of the first check valve 204 has gushed out, it will be forced to close again, and the water flow will open the second check valve 205 due to the closing of the first check valve 204, and the water pressure in the lower part of the pipe will rise due to the sudden interruption of the water flow, so that the water flow further passes through the second check valve 205 into the upper part of the second pipe above the second check valve. Therefore, the first check valve 204 and the second check valve 205 are opened and closed alternately to generate the water hammer effect repeatedly, so that water flows into the water pipe 1, indirectly flows out of the first check valve 204 and slowly flows out of the second water outlet pipe 4.

The water flow flowing out of the second water outlet pipe 4 enters the ceiling sprinkling irrigation device 5 and is irrigated under the action of the ceiling sprinkling irrigation device 5; the water flow flowing out of the first water outlet pipe 3 enters the ground flood irrigation device 6 and is irrigated under the action of the ground flood irrigation device 6; space irrigation is formed under the combined action of the ceiling sprinkling irrigation device 5 and the ground sprinkling irrigation device 6.

The operation relationship of the soil irrigation system in the greenhouse space with the water hammer is shown in figure 3. The pipeline from the water source to the hydraulic ram pump is normally open, and the control switch controls the opening and closing of two water flow output ports of the hydraulic ram pump; the switches of the two water flow outlets need to be opened and closed in the same state at the same time, otherwise, the normal use of the water pump is influenced; the water hammer pump is connected with an irrigation system of the greenhouse and is respectively connected with ceiling spray irrigation and ground flood irrigation of the greenhouse; if other requirements exist, the greenhouse can still be connected with other irrigation interfaces required by the greenhouse.

The water hammer greenhouse space soil irrigation system can convey water from the lower part of the greenhouse to the top of the greenhouse through the water hammer pump made based on the water hammer effect, and can provide a water source for an irrigation mechanism without additional functions; the water hammer pump is adopted to complete almost lossless soil greenhouse space irrigation, the soil irrigation research in the space inside the greenhouse is promoted, and the water hammer pump can be applied to energy-saving irrigation of the soil greenhouse.

While the present invention has been described in detail with reference to the embodiments, the scope of the present invention should not be limited to the embodiments. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.
