Description

TECHNICAL FIELD

[0001] The utility model relates to water tap protection device technical field, concretely is water tap protection device for farmland water conservancy irrigation. BACKGROUND

[0002] In the farmland water conservancy irrigation system, the water tap is the key infrastructure to realize effective irrigation, and its installation stability directly affects the normal operation and service life of the irrigation system.

[0003] In practical application, when the water tap is opened for irrigation, the water flow from the water tap has a great impact force, which will directly act on the soil near the water tap. With the passage of time, under the continuous erosion of the water flow, the soil particles around the water tap are continuously taken away, causing the soil structure to gradually loosen.

[0004] Once the soil structure is destroyed, it will cause serious soil erosion problems. And this soil erosion poses a great threat to the installation stability of the water tap. Without the effective support of the surrounding soil, the water tap may tilt, loosen or even displace, thereby affecting the normal use of the water tap.

[0005] Although there are some protection measures for the water tap at present, most of them cannot fundamentally solve the damage to the installation stability of the water tap caused by soil erosion due to water flow impact. For example, some protection methods only simply divert the water flow without fully considering the erosion of the water flow impact on the soil; some others focus on the reinforcement of the water tap itself, ignoring the protection of the surrounding soil.

[0006] Therefore, it is urgent to develop a protection device that can effectively prevent water and soil loss near the water tap and thus ensure the installation stability of the water tap. This not only helps to improve the reliability and efficiency of the farmland water conservancy irrigation system, but also reduces the maintenance cost and water resource waste caused by the water tap problem, which is of great significance to promote sustainable agricultural development.

[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0021] Please refer to Figs. 1-2 The utility model discloses a water tap protection device for farmland water conservancy irrigation, which comprises a water tap 1, two corresponding rotating shafts welded on the outer wall of the water tap 1, a slope plate 2 installed on the two rotating shafts, an avoiding groove 3 designed at one end of the slope plate 2, and a rotating groove opened at both sides of the avoiding groove 3 and close to the end part. The rotating shafts are just placed in the rotating grooves, which makes the slope plate 2 rotate flexibly on the water tap 1 with the rotating shafts as the center.

[0022] When the protection device needs to be used, the slope plate 2 is rotated and located at the front side of the water outlet hole of the water tap 1. During the rotation, the avoiding groove 3 can skillfully avoid the water tap 1, so that the end part of the slope plate 2 is stably placed on the ground and forms an inclined state. At this time, the water flowing out of the water tap 1 directly impacts the slope plate 2, and then flows into the water channel along the slope plate 2. In this way, the direct impact of water on the soil near the water tap 1 is effectively avoided, the soil structure is protected, and the water and soil loss is reduced.

[0023] In order to further reduce the impact force of the flowing water, an extension cylinder 4 is sleeved on the slope plate 2. The two sides of the end part of the slope plate 2 away from the rotating shafts are connected with limiting blocks 6, and the two sides of the extension cylinder 4 are provided with side holes 5. The limiting blocks 6 can be accurately placed in the side holes 5. During use, the extension cylinder 4 is stretched on the slope plate 2 until the limiting blocks 6 are in contact with the end wall of the side hole 5, so as to limit the extension cylinder 4. In this way, the included angle between the slope plate 2 and the ground is reduced. Since the water flowing on the slope plate 2 will produce friction with the surface of the slope plate 2, the extension cylinder 4 increases the length of the slope plate 2, and accordingly increases the friction distance of the water flow and the surface of the slope plate 2. In the process of overcoming the friction force to do work, the water flow consumes more mechanical energy, so that the water flow speed is further reduced, thereby greatly reducing the impact and erosion on the bottom surface and the surrounding environment.

[0024] Two corresponding fixed ears 7 are connected to the side wall of the water tap 1, and a plug rack 8 can be inserted into the fixed ear 7. The plug rack 8 is connected by a U-shaped plate and a plug rod, and the plug rod is located on one side of the U-shaped plate. When the slope plate 2 needs to be fixed, the plug rod is placed vertically, the U-shaped plate of the plug rack 8 is inserted along the side of the slope plate 2, and then it is slid downward, so that the plug rod is smoothly inserted into the fixed ear 7, thereby realizing the firm fixation of the slope plate 2.

[0025] The water on the slope plate 2 and the extension cylinder 4 will naturally drip downward under the action of gravity, so that the surface can be kept dry. This design not only facilitates long-term use of the device, but also effectively prevents accidental trampling by personnel, thereby protecting the slope plate 2 and the extension cylinder 4 and prolonging the service life of the device.

[0026] In summary, the water outlet tap 1 protection device for farmland irrigation is used as follows: before irrigation using the water outlet tap 1 protection device, the state of each component of the device is observed. The plug-in bracket 8 on the fixed lug 7 of the side wall of the water outlet tap 1 is found to have been installed (if the slope plate 2 has been fixed after previous use), and the plug-in bracket 8 is pulled out of the fixed lug 7 to release the fixed state of the slope plate 2.

[0027] The slope plate 2 is held and rotated to the front of the water outlet tap 1 by using two corresponding rotating shafts welded on the outer wall of the water outlet tap 1 (the rotating shafts are arranged in rotating grooves on both sides of the avoidance groove 3 at one end of the slope plate 2), and the avoidance groove 3 avoids the water outlet tap 1 during the rotation process until the end of the slope plate 2 contacts the ground, so that the slope plate 2 is in an inclined state.

[0028] After the slope plate 2 is unfolded, the extension cylinder 4 is always installed on the slope plate 2 and cannot be removed, but can only slide on the slope plate 2. The two sides of the end of the slope plate 2 away from the rotating shaft are connected with limit blocks 6, and the two sides of the extension cylinder 4 are correspondingly provided with side holes 5. The extension cylinder 4 is stretched along the slope plate 2 until the limit blocks 6 on the slope plate 2 are clamped into the end wall of the side holes 5 of the extension cylinder 4, at which time the extension cylinder 4 and the slope plate 2 are in an inclined state together, and the angle between the slope plate 2 and the ground is further reduced. Because of the limiting effect of the limit blocks 6, the extension cylinder 4 will not fall off the slope plate 2 and can stably work with the slope plate 2.

[0029] After the above steps are completed, the water outlet tap 1 is opened for irrigation. The water flowing out of the water outlet tap 1 will first impact on the slope plate 2 and the extension cylinder 4. Because of the existence of the slope plate 2 and the extension cylinder 4, the water flow will generate friction with the surface when flowing on the surface. The extension cylinder 4 increases the length of the slope plate 2, which increases the friction distance of the water flow with the surface of the slope plate 2. The water flow overcomes the friction force to do work, consumes more mechanical energy, and further reduces the water flow speed. Subsequently, the water flow flows into the canal along the slope plate 2 and the extension cylinder 4. This design effectively reduces the impact force of the water flow on the bottom surface, avoids the direct impact of the water flow on the soil near the water outlet tap 1, protects the soil structure, and reduces water and soil loss.

[0030] After irrigation, since the extension cylinder 4 cannot be removed and can only slide on the slope plate 2, push the extension cylinder 4 back along the slope plate 2 to disengage the limiting block 6 from the end wall of the side hole 5, and reset the extension cylinder 4 to its initial state. Then, hold the slope plate 2 and rotate it in the opposite direction, using the pivot to rotate the slope plate 2 to the position where it fits against the water outlet 1. During the rotation, the clearance groove 3 continues to avoid the water outlet 1. Finally, straighten the insertion rod of the insert bracket 8, insert the U-shaped plate of the insert bracket 8 along the side of the slope plate 2, and then slide it down so that the insertion rod is inserted into the fixing ear 7, completing the fixation of the slope plate 2. The water on the slope plate 2 and the extension cylinder 4 will drip down naturally under the action of gravity, allowing the surface to dry. The entire protective device is now ready for reuse.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
