Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water supply and drainage, in particular to a water discharge facility. Background Art
[0002] Installing drainage facilities near farmland is a crucial component of agricultural irrigation and drainage management. These facilities are crucial for ensuring crops receive adequate water, improving water resource utilization efficiency, and preventing soil salinization and swamping. However, in many areas, field drainage facilities still rely on traditional manual adjustment methods, such as simple wooden or iron gates and simple valves. These facilities have simple structures and require manual adjustment, resulting in slow response and low drainage efficiency.
[0003] With the popularization of actuators such as solenoid valves, existing water release facilities mostly use remote control methods. When the water level rises to a certain height, the solenoid valve is opened in time to release water. However, the procurement cost of this type of actuator is relatively high, and it is not suitable for promotion in a large number of small farmland projects. In addition, personnel are still required to monitor the water level and respond in a timely manner, which consumes huge manpower and material resources. Utility Model Content
[0004] The utility model provides a water discharge facility, which can solve the technical problem of high construction and maintenance costs of existing water discharge facilities used beside ordinary farmland.
[0005] This application provides the following technical solutions:
[0006] A water discharge facility is placed as a whole on the slope of a farmland, and includes a base plate and side walls on both sides of the base plate, the base plate and the side walls enclosing a drainage channel, the end of the drainage channel away from the farmland is a water inlet, a slot is provided in the water inlet along the vertical direction, a water baffle is inserted in the slot, and the water baffle is fitted with a gap between the slot; it also includes a float for detecting the water level, and a telescopic rod 1 and a telescopic rod 2 for fixedly connecting the water baffle and the float, a triangular structure is formed between the telescopic rod 1, the telescopic rod 2 and the water baffle, and locking members for locking the telescopic rod 1 and the telescopic rod 2 are provided on the telescopic rod 1 and the telescopic rod 2; the base plate includes an integrally formed horizontal section and an inclined section, a waterfall step is fixedly provided on the inclined section, and an arc-shaped steep slope is fixedly provided at the end of the inclined section.
[0007] Beneficial effects:
[0008] 1. Reduced manufacturing and maintenance costs of the water discharge system: By connecting the float and water baffle via telescopic rods 1 and 2 to form a single floating unit, water level changes can be monitored in real time. When the water level rises, the float rises with it, driving the water baffle upward along the slot, automatically opening the water inlet. This design enables automatic water level control without the need for manual intervention or maintenance. When the water level drops, the float drops, and the water baffle follows, closing the water inlet. This automatic control mechanism ensures that the water discharge system can respond promptly to actual water level changes, improving the efficiency and accuracy of water discharge. Furthermore, the overall structure is compact and simple, consisting primarily of a base plate, side walls, water baffle, float, and telescopic rods. It lacks high-cost actuators such as solenoid valves, resulting in low material and manufacturing costs, making it suitable for widespread application in numerous small-scale farmland projects.
[0009] 2. Control the flow rate of water to prevent flooding of farmland: A fixed waterfall step is installed on the inclined section of the base plate, and a fixed curved steep slope is installed at the end of the inclined section. As the water retaining plate slowly moves upward, the water flows down the waterfall step by step through the curved steep slope, effectively limiting the flow rate. This design prevents water from rushing into farmland too quickly and avoids the impact of sudden large-scale water release on farmland, protecting crops and ensuring more uniform and controllable irrigation and drainage of farmland.
[0010] Furthermore, as an improvement, the two ends of the telescopic rod 1 are respectively hinged to the float and the water baffle, and the two ends of the telescopic rod 2 are respectively hinged to the float and the water baffle.
[0011] Beneficial effect: Through the hinged design of the telescopic rod 1 and the telescopic rod 2, the fixed height of the float relative to the waterproof board can be flexibly adjusted to meet the needs under different water level conditions.
[0012] Furthermore, as an improvement, waterproof paint is applied to the water retaining plate.
[0013] Beneficial Effects: By applying waterproof paint to the outer surface of the water retaining plate, its waterproof performance is significantly enhanced. A dense protective film forms on the paint, effectively preventing moisture from penetrating the inner surface of the water retaining plate, causing swelling, deformation, or rotting. This enhanced waterproofing ensures the stability and reliability of the water retaining plate in humid environments, while also preventing the water retaining plate from becoming stuck in the slot and unable to move with the float.
[0014] Furthermore, as an improvement, the float is a rubber ball.
[0015] Benefits: The rubber ball has excellent buoyancy and flexibility, allowing it to quickly rise and remain stable on the surface when the water level rises. The lower density of rubber than water ensures sufficient buoyancy in water, allowing it to respond quickly to even small changes in the water level. This stability ensures reliable performance in various water environments and reduces the risk of misjudgment.
[0016] Furthermore, as an improvement, the telescopic rod includes a sliding-fitting pull rod and a sleeve, the locking piece is a set screw, a through hole is opened on the sleeve, and several threaded holes are opened on the pull rod, and the set screw passes through the through holes in turn and is threadedly connected to the threaded holes.
[0017] Benefits: By providing multiple threaded holes in the rod, each corresponding to a fixed length, the telescopic rod can be precisely locked at different lengths, eliminating the ambiguity and inaccuracy of traditional adjustment methods. The threaded connection of the set screw provides a reliable locking effect, ensuring the stability and reliability of the telescopic rod after adjustment. Even when subjected to external forces, the set screw effectively prevents the rod from slipping, maintaining its fixed position and enhancing the stability of the overall structure.

[0019] Figure 2 for Figure 1 AA section view;
[0020] Figure 3 for Figure 2 Schematic diagram of the structure of the middle float, telescopic rod 1, telescopic rod 2, and water baffle. DETAILED DESCRIPTION
[0021] The following is further described in detail through specific implementation methods:
[0022] The marks in the drawings of the specification include: farmland 1, bottom plate 2, horizontal section 21, inclined section 22, side wall 3, slot 4, water retaining plate 5, float 6, telescopic rod 1 7, pull rod 71, sleeve 72, telescopic rod 2 8, locking piece 9, waterfall step 10, arc-shaped steep slope 11, and connecting piece 12.
[0023] Example 1
[0024] Combine Figure 1-Figure 3As shown, a water discharge facility is placed as a whole in the slope of farmland 1, including a base plate 2 and side walls 3 on both sides of the base plate 2. The base plate 2 and the side walls 3 are both cast by concrete. The base plate 2 and the side walls 3 form a drainage channel with a trapezoidal cross-section. The end of the drainage channel away from the farmland 1 is a water inlet, and the end close to the farmland 1 is a drainage outlet. A slot 4 is opened in the water inlet in the vertical direction, and a water retaining plate 5 is inserted in the slot 4. The water retaining plate 5 is a wooden board with waterproof paint on the outside. The water retaining plate 5 is fitted with the slot 4 so that the water retaining plate 5 can slide in the vertical direction along the slot 4.
[0025] It also includes a float 6 for detecting the water level, and a telescopic rod 1 7 and a telescopic rod 2 8 for fixing the water baffle 5 and the float 6. In this embodiment, the float 6 is a rubber ball. When the water level rises, the float 6 will follow and float to the surface of the water. Figure 3 The triangular structure shown in the figure features locking members 9 on both telescopic rods 1 (7) and 2 (8), respectively, for locking them. Telescopic rod 1 (7) comprises a slidingly mated pull rod 71 and sleeve 72. In this embodiment, the locking member 9 is a set screw. Sleeve 72 has a through hole, while pull rod 71 has several threaded holes. To adjust pull rod 71 to the desired length, simply tighten the set screw, threading it through the through holes and into the threaded holes to secure it. Telescopic rod 2 (8) and telescopic rod 1 (7) are identical in structure and are both made of plastic.
[0026] The base plate 2 includes an integrally formed horizontal section 21 and an inclined section 22. A three-level waterfall step 10 is fixedly arranged on the inclined section 22. The waterfall step 10 is made of cast concrete. An arc-shaped steep slope 11 is fixedly arranged at the end of the inclined section 22. The arc-shaped steep slope 11 is formed by artificially excavating the farmland 1. The apex of the arc-shaped steep slope 11 is located on the plane line of the farmland 1.
[0027] Connectors 12 are provided between the telescopic rod 1 (7) and the float 6, and between the telescopic rod 1 (7) and the water baffle 5. The ends of the telescopic rod 1 (7) are hingedly connected to the connectors 12. Connectors 12 are also provided between the telescopic rod 2 (8) and the float 6, and between the telescopic rod 2 (8) and the water baffle 5. The ends of the telescopic rod 2 (8) are respectively hingedly connected to the connectors 12. By adjusting the length of the telescopic rod 1 (7) and the telescopic rod 2 (8), the fixed height of the float 6 relative to the water baffle 5 can be adjusted, which facilitates adjusting the timing and amount of water release according to actual needs.
[0028] The specific application process is as follows:
[0029] During use, when the liquid level begins to rise, the float 6 floats up with the liquid level. Since the float 6 and the water baffle 5 form a stable triangular fixed connection relationship by means of the telescopic rod 1 7 and the telescopic rod 2 8, the water baffle 5 slides upward in the vertical direction along the slot 4 under the traction of the float 6, thereby slowly opening the water inlet, thereby allowing the water flow to enter the drainage channel surrounded by the bottom plate 2 and the side wall 3 (flowing from the horizontal section 21 to the inclined section 22). It is worth noting that after the water flow enters the inclined section 22, it flows in a waterfall-like manner to the curved steep slope 11 under the influence of the three-level waterfall ladder 10. Compared with the traditional right-angled steep slope, the curved steep slope 11 is conducive to making the water flow smoother and reducing the turbulence of the water flow when passing through the steep slope, thereby reducing the scouring effect of the water flow on the bottom and sides of the steep slope to prevent a large amount of water flow from splashing onto the nearby farmland 1 and flooding the crops.
[0030] The above is only an embodiment of the present invention. The present invention is not limited to the field involved in this implementation case. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
