Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy irrigation, in particular to a water conservancy irrigation device for a water conservancy project. Background Art

[0002] A water conservancy irrigation canal is a water conservancy ditch facility used to irrigate farmland, woodland, etc. It transports water from the water source to various places that need irrigation through an anti-seepage main canal, and then allows the water in the main canal to enter the branch canal for irrigation.

[0003] The main channel of the irrigation canal is generally connected to a high water source point, and is connected to a branch channel during the extension process to divert the water supply. However, during the flood season when the rain is heavy or the water level at the water source is high, the water flows from the main channel into the branch channel with a large flow rate, and then enters the field through the branch channel. This is not only easy to cause over-irrigation, but also the excessively fast irrigation water flow can easily directly impact the plants, thereby affecting the growth of the plants. There is still a certain inconvenience in actual use. Therefore, there is an urgent need for a water conservancy irrigation device for water conservancy projects to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a water conservancy irrigation device for water conservancy projects, so as to solve the problem that the main channel of the irrigation canal proposed in the above-mentioned background technology is generally connected to a high-level water source point, and is connected to the branch channel during the extension process, so as to divert the water supply. However, during the flood season when the rain is heavy or the water level at the water source is high, the water flows from the main channel into the branch channel with a large flow rate, and then enters the field through the branch channel, which not only easily leads to over-irrigation, but also the excessively fast irrigation water flow easily directly impacts the plants, thereby affecting the growth of the plants. There are still certain inconveniences in actual use.

[0005] The utility model provides the following technical solution: a water conservancy irrigation device for a water conservancy project, comprising an irrigation mechanism, wherein the irrigation mechanism comprises a U-shaped main channel with an open top and branch channels distributed on both sides thereof, the two channels are internally connected for water liquid transportation;

[0006] A shielding mechanism is arranged at the interface between the main channel and the branch channel, and the shielding mechanism includes a hidden sleeve with an open side and a cavity inside, and the hidden sleeve is embedded and installed in the inner wall of the interface between the main channel and the branch channel, a shielding plate is inserted and slid in the hidden sleeve, and after the shielding plate is fully extended, the water inlet of the branch channel is shielded, the tail of the shielding plate is evenly connected with a spring, and the tail end of the spring is connected to the inner wall of the cavity of the hidden sleeve, and a water retaining plate is connected to the extended end of the shielding plate, and the water retaining plate is inside the main channel for withstanding the impact of water.

[0007] To implement the above technical solution, a water retaining plate is impacted by high-speed water flow, which drives the baffle plate to block a large area of ​​the water inlet of the branch channel, thereby preventing a large amount of water from quickly pouring into the branch channel and preventing the subsequent farmland irrigation from being affected. Compared with the existing technology, the present device can quickly change the water inflow of the branch channel during the flood season, avoiding the destructive effects of a large amount of water on farmland crops, making the present device more convenient for staff to use.

[0008] Furthermore, shielding covers are placed on the top of the main channel and the branch channel, and the shielding covers are metal components composed of multiple sections bonded together.

[0009] To implement the above technical solution, simply block the tops of the main channel and branch channels.

[0010] Furthermore, a filter screen plate is provided at the bottom end of the inner wall of the water inlet of the branch channel and fixed by screws. The filter screen plate is inclined and the inclination direction is toward the water inlet of the branch channel.

[0011] Implementing the above technical solution can reduce the probability of foreign matter entering the branch channel.

[0012] Furthermore, a rubber ring is sleeved and fixed on the outer surface of the shielding plate outside the hidden sleeve, and when the water retaining plate is not impacted, the rubber ring is tightly fitted with the side opening of the hidden sleeve under the tension of the spring.

[0013] By implementing the above technical solution, the hidden cover is less likely to be accidentally infiltrated with water under normal circumstances.

[0014] Furthermore, a limiting hole is provided on the shielding plate, and the number of the limiting hole is at least one, a limiting seat is provided in the limiting hole, and both sides of the limiting seat are connected to the inner wall of the cavity of the hidden sleeve.

[0015] Implementing the above technical solution can improve the guidance of the movement of the shielding plate.

[0016] Furthermore, the height of the water retaining sheet is half of the height of the shielding plate, and the installation position is located on the side of the shielding plate. The water retaining sheet is inclined, and the inclination direction is toward the direction of water flow impact.

[0017] The implementation of the above technical solution makes the water retaining plate more susceptible to the impact of water flow with a higher water level and a faster flow rate.

[0018] Technical effects and advantages of the utility model:

[0019] 1. The utility model adopts a water retaining plate that is impacted by high-speed water flow, driving the shielding plate to shield the water inlet of the branch channel over a large area, thereby preventing a large amount of water from quickly pouring into the branch channel and preventing the subsequent farmland irrigation from being affected.

[0020] 2. Compared with the prior art, the utility model can quickly change the water inflow of the branch channel during the flood season, avoiding the destructive effect of a large amount of water on farmland crops, making the device more convenient for staff to use.

The shielding mechanism 2 includes a hidden sleeve 210 with an open side and a cavity inside, and the hidden sleeve 210 is embedded and installed in the inner wall of the interface between the main channel 110 and the branch channel 111. A shielding plate 211 is inserted and slid in the hidden sleeve 210, and after the shielding plate 211 is fully extended, the water inlet of the branch channel 111 is shielded, and the tail of the shielding plate 211 is evenly connected with a spring 213, and the tail end of the spring 213 is connected to the inner wall of the cavity of the hidden sleeve 210, and the extended end of the shielding plate 211 is connected with a water retaining sheet 212, and the water retaining sheet 212 is inside the main channel 110. , used to withstand the impact of water, the outer surface of the baffle plate 211 outside the hidden sleeve 210 is sleeved and fixed with a rubber ring 216, and when the water retaining sheet 212 is not impacted, the rubber ring 216 is tightly fitted with the side opening of the hidden sleeve 210 under the tension of the spring 213, and a limiting hole 214 is provided on the baffle plate 211, and the number of the limiting hole 214 is at least one, and a limiting seat 215 is provided in the limiting hole 214, and both sides of the limiting seat 215 are connected to the inner wall of the cavity of the hidden sleeve 210, the height of the water retaining sheet 212 is half of the height of the baffle plate 211, and the installation position is located on the side of the baffle plate 211, and the water retaining sheet 212 is inclined, and the inclination direction is toward the direction of water impact.

[0030] In normal times, the water flow in the main channel 110 is slow and the liquid level is low, which makes it difficult to effectively impact the water retaining plate 212, so that the shielding plate 211 is pulled by the spring 213 and hidden in the hidden sleeve 210, and will not block the water inlet of the branch channel 111;
