Technical field

The utility model relates to a water supply device applied to a pipe network type immersion irrigation terminal, in particular to an automatically controllable water supply device applied to a pipe network type immersion irrigation terminal. Background technique

In order to overcome the problem of land desertification, most countries use vegetation construction. However, because the desertification areas are mostly windy and sandy, precipitation is scarce, and surface water is relatively poor, the survival rate of seedlings is very low. In order to solve the problem of water supply during the seedling period, the inventor of the present invention issued the Chinese utility model patent of CN2698063Y, which provides an automatic balanced and adjustable underground pipe network infusion device, and the pipe network infusion device is provided with water. a container, at least one water outlet is arranged at the bottom of the water container, the water outlet is connected with a water delivery main pipe through a valve, a water delivery branch pipe is connected to the water delivery main pipe, and the seedling is soaked on the water transfer branch pipe as needed The number of corresponding irrigation belts was set to solve the problem of water supply per seedling. The technical solution provided by this patent saves a lot of water. However, there are still further improvements that need to be made as follows: Since the impregnation zone for impregnation of each seedling is directly placed on the water supply branch pipe, since the water supply branch pipe is a relatively closed pipeline, pressure will be generated during use, Seedlings at the distal end of the water pipe cannot be simultaneously flooded at the same time. Utility model content

In order to overcome the above drawbacks, the utility model aims to provide a pipe network type irrigation terminal automatic control water supply device, and provide a water supply device capable of automatically controlling its own water level for each seedling, thereby realizing timely irrigation of each seedling. In order to achieve the above object, the present invention provides a pipe network type irrigation terminal automatic control water supply device, comprising a closed container, the container is provided with an inlet pipe; an upper portion of the container is provided with an outlet pipe, and the outlet pipe is An impregnation zone is worn; a liquid level switch is arranged in the container corresponding to the water inlet pipe. The water level of the inlet pipe is controlled by the liquid level switch to ensure that a certain volume of water is always maintained in the container, and the seedlings are immersed in time through the submerged zone in the outlet pipe.

As a preferred embodiment of the present invention, one end of the dip belt extends to the bottom surface of the container to further ensure that the submerged strip can draw sufficient water into the container.

As a preferred solution of the present invention, the liquid level switch is a float switch. As a preferred structure of the present invention, the float switch includes: a connecting rod hinged to an upper portion of the inner side wall of the container, a float fixed to the free end of the connecting rod; and the connecting rod is provided with a float when floating The gasket for sealing the nozzle of the inlet pipe has a simple structure of the float switch of this structure, and the manufacturing cost H is suitable for popularization and application.

Preferably, the gasket is a rubber mat which is both sealed and inexpensive, and is suitable for use in large quantities.

As an improvement of the utility model, the upper surface of the container is provided with air holes to ensure that the pressure inside and outside the container is equal, and the water can smoothly immerse the seedlings through the dip zone.

The utility model has the advantages that: the water supply device is automatically controlled by the pipe network type immersion irrigation terminal, and the seedlings are timely immersed in time. By connecting the automatic control water supply device to the water supply branch pipe located in the pipe network type irrigation terminal, the water outlet valve that needs manual adjustment is omitted, and the liquid level switch is set in the automatic control water supply device, after the water in the container reaches the set water level. , automatically close the inlet pipe; when the water level in the container is lower than the set water level, open the inlet pipe to replenish the water until the set water level is reached, ensure that the water is always filled in the immersion zone, and timely irrigate the water-deficient seedlings.

The utility model has the advantages of simple structure, low manufacturing cost and suitable for popularization and application. The utility model is suitable for plant irrigation in any region, and is particularly suitable for plant irrigation in water-deficient areas, and can achieve good irrigation effect with minimum water.

The present invention will be described in detail below with reference to the accompanying drawings.

The pipe network type immersion irrigation terminal of the utility model automatically controls the water supply device, and the water delivery branch pipe connected to the pipe network immersion device terminal comprises a closed container, the container is provided with an inlet pipe, the inlet end of the inlet pipe and the water delivery The branch pipe is connected, and an upper portion of the container is provided with an outlet pipe. The outlet pipe may be located on the upper surface of the container or on the upper side of the container side as long as it is higher than the set water level in the container. The water outlet pipe is provided with an impregnation zone; a liquid level switch is arranged in the container corresponding to the water inlet pipe, and the water inlet pipe is automatically switched through the liquid level switch to ensure that the water in the container is always at the set water level. The liquid level switch can adopt any one of the prior art, and a suitable liquid level switch can be adopted according to the use region, economic conditions and the like.

As shown in Figure 1, an embodiment of the present invention, the upper surface of the closed container 8 is provided with an inlet pipe 2, a water inlet end of the inlet pipe 2 and a water delivery branch of the pipe network dipper terminal (not shown). The upper surface of the container 8 is provided with an outlet pipe 4, and the water outlet pipe 4 is provided with an impregnation zone 5; one end of the outlet pipe 4 extends into the container 8 for a length, and the other end extends out of the container. Extend outward and downward to ensure that the dip zone 5 can reach the root of the seedling. Said One end of the dip zone 5 extends to the bottom surface of the container 8, and the other end projects out of the water pipe 4 for a length. The liquid level switch is a float switch. The specific structure is: a connecting rod 9 hinged to the upper part of the inner side wall of the container 2, the fixed position of the connecting rod 9 determines the set water level of the container 2; the float 7 fixed to the free end of the connecting rod; A gasket is provided. In this example, the gasket is made of rubber pad 1. When the liquid level switch of this structure is used, as a corresponding structure, the inlet pipe is located at one end of the container and protrudes into the container to an appropriate length to float the float. At the beginning, the rubber mat 1 can just seal the nozzle of the inlet pipe to achieve the purpose of controlling the water level. In order to ensure the normal operation of the submerged strip 5, the upper surface of the container 8 is provided with air holes 3.

When applied, three-quarters of the container 8 can be buried next to the seedlings, and the outlet pipe 4 will be extended into the soil 6 next to the seedlings. Through the water inlet pipe 2, water flows into the container 8, and as the water level rises, the float 7 is floated. When the set water level is reached, the rubber mat 1 seals the water inlet pipe 2 and stops the water supply into the container 8. The roots of the seedlings are immersed by the water through the immersion zone 5. When the water level is lowered, the position of the float 7 is lowered, the rubber pad 1 is separated from the nozzle of the inlet pipe 2, and the water enters the container 8. In this way, the irritable strip is always filled with water and the seedlings are irrigated in time.
