Description

Automatic moisture-sensing watering device

technical field

The utility model relates to a watering device, in particular to an automatic moisture-sensing watering device.

Background technique

In the experimental field, the growth process of various vegetation used for scientific research is inseparable from watering. At present, most of the watering is carried out manually, which is time-consuming and labor-intensive. There are even cases where no watering is performed during the holidays. Therefore, there is a need for an automatic watering device that meets the needs of large-area experimental fields, detects soil moisture and waters automatically, and can adjust the watering method for different plants, so as to achieve high efficiency and water saving.

SUMMARY OF THE INVENTION

In view of the defects in the prior art, the utility model provides an automatic moisture-sensing watering device, which is simple in structure and reliable in function, and can realize efficient watering saving.

In order to achieve the above purpose, the technical solutions adopted are as follows:

An automatic moisture-sensing watering device, comprising a main control valve, a soil moisture sensor connected to the main control valve, and a plurality of sprinklers connected to the water outlet of the main control valve through pipelines, the sprinkler heads comprising a sprinkler head body and a sprinkler head body connected to the sprinkler head body The plunger at the lower end, the side of the plunger is provided with a water inlet, the nozzle body is provided with a plurality of nozzles that communicate with the water inlet, the nozzle body is rotatably installed with an adjustment cover, and the adjustment cover includes The enclosure of the back plate and the edge of the back plate, the enclosure surrounds the outer periphery of the nozzle and leaves a gap with the nozzle, and the enclosure is provided with a water outlet corresponding to the nozzle, and the adjustment cover is rotated to make the The water outlet and the nozzle of the nozzle are directly aligned or staggered.

Further, a plurality of locking feet are arranged along the circumference on the inner side of the back plate of the adjusting cover, and the adjusting cover is rotatably mounted on the spray head through the locking feet.

Further, the enclosure is in a circular arc shape, and the clearance distance between the inner side of the enclosure and each nozzle is equal.

Further, the soil moisture sensor is composed of a sensor body and a relay module, and the relay module is connected to the main control valve.

When the watering device is in use, the water inlet of the main control valve is connected to the water source, and an appropriate amount of sprinklers are arranged at the appropriate position of the experimental field. The spray head in this device has two spraying methods. When the adjusting cover is rotated so that the water outlet holes on it are facing each nozzle, the water flow is sprayed out from the nozzles through the water outlet holes in the form of water column, forming several strands of radiation to the side. Thin water column. When the adjusting cover is rotated to make the water outlet and the nozzle staggered, the water flows through the nozzle and is blocked by the adjusting cover to form a water mist, which is sprayed forward from the front of the nozzle through the gap. It can be seen that two water spraying methods can be realized by rotating the adjusting cover, so that targeted watering can be realized according to different growth conditions of different plants. The soil moisture sensor is inserted into the soil, when it is detected that the humidity is lower than the set value, the main control valve can be controlled to open the water, and water is poured through the above sprinklers. When the soil moisture reaches the set value, the main control valve The valve is disconnected, thereby realizing the automatic moisture-sensing watering function of the device.

Detailed ways

The embodiments of the technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

As shown in the figure, the automatic moisture-sensing watering device includes a main control valve 2, a soil moisture sensor connected to the main control valve, and a plurality of sprinklers 1 connected to the water outlet of the main control valve through pipelines.

The spray head 1 includes a spray head body 11 and an insertion rod 12 connected to the lower end of the spray head body. A water inlet 13 is provided on the side of the insertion rod, and the spray head can be firmly inserted into the soil through the insertion rod 12 .

The spray head body 11 is provided with five nozzles 14 communicating with the water inlet at an interval in the circumferential direction, and the nozzles 14 are radially outward.

The spray head body 11 is rotatably mounted with an adjustment cover 15, the adjustment cover includes a back plate 16 and an enclosure 17 on the edge of the back plate, the enclosure surrounds the outer periphery of the nozzle and leaves a gap with the nozzle, where The enclosure is provided with a water outlet hole 18 corresponding to the nozzle, and the water outlet hole and the nozzle of the spray head are directly aligned or staggered by rotating the adjusting cover (in the direction of the arrow in FIG. 3 ). A plurality of locking feet 19 are arranged along the circumference on the inner side of the back plate of the adjusting cover, and the adjusting cover is rotatably mounted on the spray head through the locking feet. The enclosure is arc-shaped, and the gap distance between the inner side of the enclosure and each nozzle is equal.

The soil moisture sensor is composed of a fork-shaped sensor body 3 and a relay module 4, and the relay module is connected to the main control valve. The soil sensor uses 12V power supply. When the humidity is lower than the set humidity, the relay is pulled in and connected to start the main control valve to open. When the humidity is lower than the set humidity, the relay is turned off. In addition, the surface of the sensor body is treated with nickel plating, which widens the sensing area, improves the electrical conductivity, prevents rusting in contact with the soil, and prolongs the service life.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, but not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features thereof can be equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention , which shall be included in the scope of the claims and description of the present invention.
