Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation, and in particular relates to a groove device for preventing scouring of farmland irrigated by a hose in a well irrigation area. Background Art

[0002] In the North China Plain, apart from larger farmers' cooperatives and large-scale growers who use sprinkler irrigation and other methods for irrigation, the vast majority of farmers still use traditional irrigation methods such as laying water belts or water pipes to the fields.

[0003] However, the water outlet of the field irrigation water belt or water pipe is large, and the water flow rate is also large. The water flow will form a strong impact force, which can easily cause surface scouring, washing away the soil around the front end of the outlet, forming a scouring pit, and causing the field to be uneven. If watering is done after sowing, the seeds can easily be washed away, affecting germination. If watering is done in the seedling stage, the seedlings can also be easily washed away, affecting yield.

[0004] In order to reduce the impact of water flow, some farmers will lay a sack at the outlet, and the water will rush onto the sack to reduce the scouring of the ground. Although this method can reduce the impact of water flow on the ground to a certain extent, the effect is limited. Moreover, due to the strong impact force of the water flow, the sack is easily washed away by the water. Utility Model Content

[0005] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a groove device for preventing scour of hose irrigation of farmland in a well irrigation area. A water storage frame with a wave plate is arranged at the bottom. The corrugations of the wave plate are used to buffer the impact of water flow, thereby preventing the water flow from scouring and damaging the land.

[0006] The specific technical solution adopted by the utility model is:

[0007] A groove device for preventing scour of a hose in a well irrigation area from being irrigated to farmland, comprising a groove-shaped water storage frame, a water outlet of the hose being located in the water storage frame, a wave-shaped wave plate being arranged at the bottom of a chamber of the water storage frame, a water outlet direction of the hose being perpendicular to a trough setting direction of the wave plate, a wave crest of the wave plate hindering the impact of water flow, water in the hose being buffered by the troughs and crests of the wave plate and being accumulated in the water storage frame before overflowing along the top opening of the water storage frame.

[0008] A wave-shaped baffle is arranged on the top of the peripheral side of the water storage frame, and the water in the water storage frame overflows along the trough of the baffle.

[0009] A fixing groove for fixing a hose is arranged on the top of a baffle plate on one side of the water storage frame, and the hose is embedded in the fixing groove to form a fixed connection with the water storage frame.

[0010] The fixing groove is a C-shaped groove, and the width of the C-shaped opening of the fixing groove is smaller than the diameter of the water outlet of the hose.

[0011] A sack is also fixed at the bottom of the water storage frame. The water storage frame is located in the middle of the sack and the area of ​​the sack is larger than the bottom area of ​​the water storage frame. Water overflowing from the water storage frame flows onto the sack to form a buffer and diffuses toward the surroundings.

[0012] The beneficial effects of the utility model are:

[0013] The utility model provides a water storage frame with a wavy bottom, and the water outflow direction is perpendicular to the wave direction of the bottom of the water storage frame. During irrigation, the water storage frame is placed below the water outlet of the hose, and water first flows into the water storage frame and rushes toward the wave plate. After the water rushes toward the wave plate, the wave direction of the wave plate will change the flow direction of the water and form a buffer. With the help of the cooperation of multiple groups of wave crests and troughs of the wave plate, the water flow speed is slowed down and a buffer is formed, thereby preventing the water flow from scouring and damaging the land.

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] Specific embodiments, such as Figure 1-3 As shown, the utility model provides a groove device for preventing scour of a hose in a well irrigation area from irrigating farmland, comprising a groove-shaped water storage frame 1, a water outlet of a hose 2 being located in the water storage frame 1, a wave-shaped wave plate 3 being arranged at the bottom of a chamber of the water storage frame 1, a water outlet direction of the hose 2 being perpendicular to a trough setting direction of the wave plate 3, a wave crest of the wave plate 3 hindering the impact of water flow, water in the hose 2 being buffered by the troughs and crests of the wave plate 3 and being accumulated in the water storage frame 1 before overflowing along the top opening of the water storage frame 1.

[0020] Since the water outlet of the field irrigation water belt or water pipe is large and the water flow rate is also large, the water flow will form a strong impact force, which can easily cause surface scouring, washing away the soil around the front end of the outlet, forming scouring pits, and causing uneven field plots; if watering is done after sowing, the seeds can easily be washed away, affecting germination; if watering is done in the seedling stage, the seedlings can also be easily washed away, affecting yield. Currently, the use of sacks for buffering by farmers is not very effective.

[0021] Therefore, the utility model provides a water storage frame 1 with a wavy bottom, and the water outlet direction is perpendicular to the wave direction of the bottom of the water storage frame 1, wherein the wave plate 3 is a foam plate, and the water storage frame 1 is a wooden board. During irrigation, the water storage frame 1 is placed below the water outlet of the hose 2, and the water first flows into the water storage frame 1 and rushes toward the wave plate 3. After the water rushes toward the wave plate 3, the wave direction of the wave plate 3 will change the flow direction of the water. With the cooperation of multiple groups of wave crests and troughs of the wave plate 3, the water flow speed is slowed down and a buffer is formed to prevent the water flow from scouring and damaging the land. In addition, since a certain amount of water will be stored in the water storage frame 1, the weight of the water storage frame 1 itself plus the weight of the stored water can prevent the water storage frame 1 from being washed away by water.

[0022] A wavy baffle 4 is provided on the top of the peripheral side of the water storage frame 1. The water in the water storage frame 1 overflows along the trough of the baffle 4. The wavy baffle 4 forms a plurality of water outlet channels on the top of the water storage frame 1, so that the water in the water storage frame 1 flows to the surroundings, thereby preventing the water in the water storage frame 1 from flowing out in a concentrated place.

[0023] A fixing groove 5 for fixing the hose 2 is provided on the top of a side baffle 4 of the water storage frame 1 , and the hose 2 is embedded in the fixing groove 5 to form a fixed connection with the water storage frame 1 .

[0024] The fixing groove 5 is a C-shaped groove, and the C-shaped opening width of the fixing groove 5 is smaller than the water outlet diameter of the hose 2, and the diameter of the hose 2 is slightly larger than the diameter of the fixing groove 5. In order to prevent the hose 2 from being separated from the water storage frame 1 by the reaction force of the water flow, the utility model is also provided with a fixing groove 5 to fix the hose 2. By means of the deformable characteristics of the hose 2, when there is no water flowing, the hose 2 is pinched and narrowed and the hose 2 is inserted into the C-shaped fixing groove 5. When the water flows, the hose 2 expands under the action of the water flow. Since the C-shaped opening width of the fixing groove 5 is smaller than the water outlet diameter of the hose 2, the fixing groove 5 limits the hose 2 in the vertical direction. At the same time, the diameter of the hose 2 is slightly larger than the diameter of the fixing groove 5. The expanded hose 2 forms a large pressure on the fixing groove 5 and increases the friction between the two, so that the fixing groove 5 limits the hose 2 in the horizontal direction, and the hose 2 is firmly fixed.

[0025] A sack 6 is also fixed to the bottom of the water storage frame 1. The water storage frame 1 is located in the middle of the sack 6 and the area of ​​the sack 6 is larger than the bottom area of ​​the water storage frame 1. Water overflowing from the water storage frame 1 falls on the sack 6 to form a buffer and diffuses toward the surroundings. Since the water storage frame 1 has a certain height, the water flowing out along the water storage frame 1 has a small amount of impact force again under the action of gravitational potential energy, which may cause the land at the edge of the water storage frame 1 to be washed into a pit. Therefore, a sack 6 is also pressed on the bottom of the water storage frame 1, and the edges of the water storage frame 1 are all above the sack 6. The sack 6 is used to form a buffer for the water flowing out along the water storage frame 1, and the water storage frame 1 is used to press the sack 6 to prevent the sack 6 from being washed away by water.
