Description

Technical Field

[0001] This utility model relates to a water distribution device for modifying farmland irrigation canals. Background Technology

[0002] In traditional farmland irrigation systems, water distribution devices typically use simple gates or T-junctions to distribute water flow, which has the following technical drawbacks:

[0003] Easy clogging problem: Weeds, silt and other impurities in open irrigation ditches can easily enter the pipes, causing key components such as ball valves and gate valves to jam, requiring frequent manual cleaning and affecting irrigation efficiency.

[0004] Uneven flow distribution: Ordinary tee pipes lack flow regulation structures, and the water distribution deviation in downstream branches can reach more than 30%, causing localized drought or waterlogging in farmland.

[0005] Based on the above problems, we designed a water diversion device for farmland irrigation canals that can divert irrigation water, intercept debris in the water, and prevent clogging of ball valves. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a water diversion device for farmland irrigation canals that can divert irrigation water, intercept debris in the water, and prevent blockage of ball valves.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A water distribution device for farmland irrigation canals includes a water distribution tank. Multiple branch pipes are arranged in a ring around the outside of the water distribution tank, with the ends of the branch pipes used to connect to ball valves. It also includes an internal pipe coaxially disposed inside the water distribution tank, with the upper end of the internal pipe lower than the upper end of the water distribution tank. A main inlet pipe is connected to the outer wall of the internal pipe and extends to the outside of the water distribution tank. The contact point between the main inlet pipe and the water distribution tank is sealed. A groove is formed on the outer wall of the internal pipe corresponding to the position of the main inlet pipe, and a filter screen is welded into the groove. A top cover structure is installed on the top of the water distribution tank. When the filter screen becomes clogged, water overflows from the upper end of the internal pipe, is filtered by the top cover structure, falls into the water distribution tank, and then flows out through the branch pipes.

[0009] Preferably, multiple reinforcing plates are welded at the bottom position on the outside of the water distribution tank.

[0010] Preferably, a diverting rod is provided at the bottom of the inner part of the built-in tube. The diverting rod is close to the main water inlet pipe, and the water flowing in from the main water inlet pipe is diverted to both sides after passing through the diverting rod.

[0011] Preferably, the top cover structure includes a cover plate and a frame body arranged parallel to the bottom of the cover plate. A connecting rod is welded between the frame body and the cover plate. A first filter screen is welded inside the frame body. The cover plate is detachably installed on the top of the water distribution tank. When the cover plate is assembled, the frame body is sleeved on the outside of the internal pipe. Water overflowing from the upper end of the internal pipe is filtered by the first filter screen and falls back into the water distribution tank. The outer wall of the frame body is attached to the water distribution tank, and the inner wall of the frame body is attached to the internal pipe.

[0012] Preferably, a stepped hole is machined on the top of the cover plate, the stepped hole corresponds to the built-in pipe, and the small end diameter of the stepped hole is smaller than the inner diameter of the built-in pipe, and a manhole cover is detachably installed at the stepped hole.

[0013] Preferably, a light-transmitting acrylic panel is embedded in the center of the manhole cover.

[0014] Preferably, a first stepped hole is provided at the axis of the light-transmitting plate, and a straight rod is inserted through the first stepped hole. A float is fixed at the lower end of the straight rod, and a limit cap is threaded to the upper end of the straight rod. When the filter is working normally, the float hangs downward under the action of gravity, and the limit cap is limited to the stepped surface of the first stepped hole. When the filtration capacity of the filter is insufficient, causing the water to rise to the height of the filter, the float is pushed upward.

[0015] The beneficial effects of this utility model are:

[0016] Multiple anti-clogging protections

[0017] Graded filtration system:

[0018] The filter screen intercepts large particles of impurities (≥3mm) to protect the downstream ball valve;

[0019] The secondary first filter provides a backup filtration path when the primary filter becomes clogged.

[0020] Self-cleaning reminder: The float water level monitoring is linked to the light-transmitting panel observation window, which facilitates timely cleaning of intercepted debris. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] See Figure 1 and Figure 2The illustrated irrigation canal water distribution device for farmland includes a water distribution tank 1. Multiple branch pipes 2 are arranged in a ring around the outside of the water distribution tank 1, with the ends of the branch pipes 2 used to connect to ball valves. It also includes an internal pipe 3, coaxially arranged inside the water distribution tank 1. The upper end of the internal pipe 3 is lower than the upper end of the water distribution tank 1. A main inlet pipe 31 is connected to the outer wall of the internal pipe 3, extending to the outside of the water distribution tank 1. The contact point between the main inlet pipe 31 and the water distribution tank 1 is sealed. A groove is formed on the outer wall of the internal pipe 3 corresponding to the position of the main inlet pipe 31, and a filter screen 32 is welded into the groove. A top cover structure 4 is installed on the top of the water distribution tank 1. When the filter screen 32 becomes clogged, water overflows from the upper end of the internal pipe 3, is filtered by the top cover structure 4, falls into the water distribution tank 1, and then flows out through the branch pipes 2.

[0032] In the above technical solution, the water pumped by the water pump enters the built-in pipe 3 through the main water inlet pipe 31. Impurities in the water are intercepted by the filter screen 32. The end of the branch pipe 2 is used to install a ball valve. The ball valve is connected to the branch pipeline. The water after passing through the filter screen 32 flows out from the branch pipe 2 and is then transported to the branch pipeline after passing through the ball valve.

[0033] The above technical solution can prevent debris in the water from clogging the ball valve during total water flow.

[0034] Water distribution tank 1 is made of 304 stainless steel with a wall thickness greater than 3mm, an inner diameter of 600mm, and a height of 160mm.

[0035] The filter screen 32 is made of 316L stainless steel with laser-cut mesh holes, the mesh size of which is φ3mm±0.2mm.

[0036] See Figure 2 As shown, multiple reinforcing plates 121 are welded at the bottom position on the outside of the water distribution tank 1.

[0037] When arranging the water distribution tank 1, a pre-embedded method is adopted. The stability of the pre-embedded water distribution tank 1 can be increased by setting the stiffening plate 121.

[0038] See Figure 2 As shown, a diversion rod 33 is provided at the bottom of the inner part of the built-in pipe 3. The diversion rod 33 is close to the main water inlet pipe 31. Water flowing in from the main water inlet pipe 31 is diverted to both sides after passing through the diversion rod 33.

[0039] In the above technical solution, a diversion rod 33 is used. The diameter of the diversion rod 33 is slightly smaller than the inner diameter of the main water inlet pipe 31. The water entering through the main water inlet pipe 31 is diverted to both sides after impacting the diversion rod 33.

[0040] This prevents water from directly impacting the filter screen 32, thus protecting the filter screen 32.

[0041] The diameter of the diverter rod 33 is 45mm.

[0042] The diffusion angle of the water after the diversion is 120° (valid when the measured flow velocity is ≤1.5m / s).

[0043] See Figure 3 and Figure 4 As shown, the top cover structure 4 includes a cover plate 41 and a frame body 42 arranged parallel to the bottom of the cover plate 41. A connecting rod 43 is welded between the frame body 42 and the cover plate 41. A first filter screen 44 is welded inside the frame body 42. The cover plate 41 is detachably installed on the top of the water distribution tank 1. When the cover plate 41 is assembled, the frame body 42 is fitted over the outside of the internal pipe 3. Water overflowing from the upper end of the internal pipe 3 is filtered by the first filter screen 44 and falls back into the water distribution tank 1. The outer wall of the frame body 42 is attached to the water distribution tank 1, and the inner wall of the frame body 42 is attached to the internal pipe 3.

[0044] In the above technical solution, the cover plate 41 is fixed to the water distribution tank 1 by screws.

[0045] When the filtration capacity of filter screen 32 is insufficient and the water pump continues to supply water, the water level will rise in the built-in pipe 3 until the water overflows from the built-in pipe 3. The overflowing water needs to be filtered by the first filter screen 44 before it can be transported downwards to avoid the overflowing water causing blockage of the ball valve.

[0046] When both filter screen 32 and the first filter screen 44 are blocked, water overflows from above the cover plate 41.

[0047] See Figure 4 As shown, a stepped hole 411 is machined on the top of the cover plate 41. The stepped hole 411 corresponds to the built-in tube 3, and the small end diameter of the stepped hole 411 is smaller than the inner diameter of the built-in tube 3. A manhole cover 412 is detachably installed at the stepped hole 411.

[0048] In the above technical solution, the design of the manhole cover 412 is adopted. When the filtration capacity of the filter screen 32 and the first filter screen 44 is insufficient and water is continuously pumped in, the water will rush upward to open the manhole cover 412 to release pressure.

[0049] See Figure 4 As shown, an acrylic light-transmitting plate 413 is embedded in the middle of the manhole cover 412.

[0050] The design of the light-transmitting plate 413 makes it easy to see the internal condition of the built-in pipe 3 directly. When too much debris is blocked, it needs to be cleaned in time. When cleaning, open the manhole cover 412 upwards.

[0051] See Figure 4 As shown, a first stepped hole 414 is provided at the axis of the light-transmitting plate 413. A straight rod 415 is inserted through the first stepped hole 414. A float 416 is fixed at the lower end of the straight rod 415. A limit cap 417 is threaded to the upper end of the straight rod 415. When the filter screen 32 is operating normally, the float 416 hangs downward under the action of gravity. At this time, the limit cap 417 is limited to the stepped surface of the first stepped hole 414. When the filtration capacity of the filter screen 32 is insufficient, causing the water to rise to the height of the ultrafiltration screen 32, the float 416 is pushed upward.

[0052] In the above technical solution, the design of the float ball 416 facilitates the observation of the water level in the built-in pipe 3 during water supply. When the float ball 416 is lifted by buoyancy, it indicates that the filter screen 32 has insufficient throughput or that the water pump is operating at excessive power. This allows for adjustments based on actual conditions.

[0053] If the flow capacity of filter screen 32 is insufficient, turn off the water pump and clean filter screen 32.

[0054] If the water pump's operating power is too high, then reduce the operating power.
