[0001] The utility model relates to the technical field of water conservancy irrigation, and specifically relates to a water conservancy irrigation device. Background Art

[0002] Water conservancy irrigation is a comprehensive science and technology used to improve the moisture condition of farmland, prevent and control drought, waterlogging, salt and alkali disasters, so as to promote stable and high-yield agriculture. Farmland water conservancy is generally called irrigation and drainage abroad. Farmland water conservancy involves hydraulics, civil engineering, agronomy, soil science, as well as disciplines such as hydrology, meteorology, hydrogeology and agricultural economy. Its task is to intercept, regulate, distribute and use agricultural water resources through engineering and technical measures, and combine agricultural technical measures to improve soil fertility, expand land use, so as to achieve the purpose of high and stable agricultural yields; among them, the nozzle is the last part that the water flow of water conservancy irrigation passes through. After the water flow is sprayed out through the nozzle, it can irrigate a large area of vegetable crops.

[0003] However, the nozzles of existing nozzles are directly exposed. The nozzle is in the environment of farmland soil for a long time, and dust and soil are easy to block the nozzle of the nozzle, resulting in the nozzle being unable to be used normally.

[0004] In view of the above problems, the present utility model is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a water conservancy irrigation device for solving the problems mentioned in the background art.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions.

[0007] The present utility model provides a water conservancy irrigation device, including a sleeve, a spray tube and a cover plate. Both the upper end and the lower end of the sleeve are open. The spray tube is slidably arranged inside the upper end of the sleeve. The upper end of the spray tube is open. The outer side surface of the spray tube is attached to the inner side surface of the sleeve;

[0008] An inner ring cavity is arranged at a position above the middle of the inner wall of the sleeve. A strip hole penetrating the spray tube is arranged at a position below the middle of the outer side surface of the spray tube. When the spray tube moves upward, the contact area between the inner ring cavity and the strip hole gradually increases;

[0009] A sealing plate is arranged at the upper port of the spray tube. A plurality of spray holes penetrating the sealing plate are evenly arranged at equal intervals on the upper surface of the sealing plate;

[0010] A support plate is vertically arranged on one side of the upper surface of the sleeve. Two opposite clamping blocks are arranged on one side of the surface of the cover plate. The upper end of the support plate is rotatably connected between the two clamping blocks. The cover plate is attached to the upper surface of the sealing plate.

[0011] Preferably, four side sliding grooves distributed in a circumferential shape are evenly arranged at equal intervals on the inner wall of the sleeve. The side sliding grooves are arranged along the height direction of the sleeve. Four sliders distributed in a circumferential shape are evenly arranged at equal intervals on the surface of the spray tube. The sliders are slidably arranged in the side sliding grooves.

[0012] Preferably, the side sliding groove passes through the inner ring cavity. The inner ring cavity is located in the middle of the side sliding groove. The side sliding groove is divided into an upper part, a middle part and a lower part by the inner ring cavity. The heights of the upper part and the lower part of the side sliding groove are the same as the height of the slider.

[0013] Preferably, the height of the strip hole is the same as the height of the inner ring cavity. There are four strip holes, which are evenly distributed in a circumferential shape at equal intervals on the surface of the spray tube.

[0014] Preferably, a plurality of spray holes are arranged in a circumferential and radial shape on the surface of the sealing plate. The sealing plate is threadedly connected to the upper port of the spray tube.

[0015] Preferably, a torsion spring is arranged at the rotating shaft positions of the upper end of the support plate and the two clamping blocks.

[0016] Preferably, the inner wall of the lower end inlet of the sleeve is provided with threads.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The slider moves up and down in the side sliding groove, playing a guiding role in the up and down movement of the spray tube. The lower port of the sleeve can be connected to a water pipe. When water does not enter the sleeve, under the action of the self-weight of the spray tube, the slider is located at the bottom of the side sliding groove. At this time, the strip hole is not communicated with the inner ring cavity, and the cover plate covers the upper surface of the sealing plate.

[0019] Dust and soil in the farmland are blocked by the cover plate and cannot contact the spray holes, so that the spray holes will not be blocked.

[0020] When water enters the sleeve, the water generates an upward thrust on the lower bottom surface of the spray tube, enabling the spray tube to move upward. During the upward movement of the spray tube, the strip hole and the inner ring cavity are gradually communicated and aligned. When the slider is located at the top of the side sliding groove, at this time, the four strip holes are completely aligned with the inner ring cavity. In this way, water can enter the interior of the spray tube through the side sliding groove, the inner ring cavity and the strip hole, and then be sprayed out from the spray holes to irrigate the soil and the crops on the soil.

[0021] During the upward movement of the spray tube, the spray tube can gradually push open the cover plate, so that all the spray holes are normally exposed, ensuring the normal spraying of water; when the water flow stops, the spray tube can slowly fall downward. During the falling process, under the action of its own weight and the torsion spring, the cover plate can return to the horizontal position again, covering all the spray holes to prevent soil or dust from blocking the spray holes.

When the spray tube 2 moves upward, the contact area between the inner ring cavity 12 and the strip hole 22 gradually increases, that is, water can enter the strip hole 22 through the inner ring cavity 12.

[0031] A sealing plate 23 is provided at the upper port of the spray tube 2, and a plurality of spray holes 24 penetrating through the sealing plate 23 are uniformly arranged at equal intervals on the upper surface of the sealing plate 23. The water in the spray tube 2 can be sprayed out from the spray holes 24.

[0032] On one side of the upper surface of the sleeve 1, a support plate 13 is vertically provided. On one side of the surface of the cover plate 3, two opposite clamping blocks 31 are provided. The upper end of the support plate 13 is rotatably connected between the two clamping blocks 31. The cover plate 3 is attached to the upper surface of the sealing plate 23, and the cover plate 3 covers all the spray holes 24, thus preventing soil or dust from blocking the spray holes 24.

[0033] Four circumferentially distributed side sliding grooves 11 are uniformly arranged at equal intervals on the inner wall of the sleeve 1. The side sliding grooves 11 are arranged along the height direction of the sleeve 1. Four circumferentially distributed sliding blocks 21 are uniformly arranged at equal intervals on the surface of the spray tube 2. The sliding blocks 21 are slidably arranged in the side sliding grooves 11, and the sliding blocks 21 can move up and down in the side sliding grooves 11.

[0034] The side sliding groove 11 passes through the inner ring cavity 12. The inner ring cavity 12 is located in the middle of the side sliding groove 11. The side sliding groove 11 is divided into an upper part, a middle part and a lower part by the inner ring cavity 12. The height of the upper part of the side sliding groove 11, the height of the lower part and the height of the sliding block 21 are the same. When the sliding block 21 moves to the upper part of the side sliding groove 11, the inner ring cavity 12 is aligned with the strip hole 22.

[0035] The height of the strip hole 22 is the same as the height of the inner ring cavity 12. There are four strip holes 22, which are uniformly arranged in a circumferential and equidistant manner on the surface of the spray tube 2.

[0036] A plurality of spray holes 24 are arranged in a circumferential and radial manner on the surface of the sealing plate 23. The sealing plate 23 is threadedly connected to the upper port of the spray tube 2, so that the sealing plate 23 can be disassembled for maintenance.

[0038] Threads are provided on the inner wall of the lower end inlet of the sleeve 1.

[0039] In summary: The slider 21 moves up and down within the side chute 11, guiding the up and down movement of the spray tube 2, and the lower port of the sleeve 1 can be connected to a water pipe; when no water flows into the sleeve 1, under the self-weight of the spray tube 2, the slider 21 is located at the bottom of the side chute 11. At this time, the slot holes 22 are not connected to the inner ring cavity 12, and the cover plate 3 covers the upper surface of the sealing plate 23;

[0040] Dust and soil in the farmland are blocked by the cover plate 3 and cannot contact the spray holes 24, so that the spray holes 24 will not be blocked;

[0041] When water flows into the sleeve 1, the water generates an upward thrust on the lower bottom surface of the spray tube 2, enabling the spray tube 2 to move upward. During the upward movement of the spray tube 2, the slot holes 22 and the inner ring cavity 12 are gradually connected and aligned. When the slider 21 is located at the top of the side chute 11, at this time, the four slot holes 22 are completely aligned with the inner ring cavity 12. In this way, water can enter the interior of the spray tube 2 through the side chute 1, the inner ring cavity 12, and the slot holes 22, and then be ejected from the spray holes 24 to irrigate the soil and the crops on the soil;

[0042] During the upward movement of the spray tube 2, the spray tube 2 can gradually push open the cover plate 3, so that all the spray holes 24 are normally exposed, ensuring the normal ejection of water; when the water flow stops, the spray tube 2 can slowly fall downward. During the downward movement, the cover plate 3 can return to the horizontal position under the action of its own weight and the torsion spring, covering all the spray holes 24 to prevent soil or dust from blocking the spray holes 24.
