Description

Technical Field

[0001] This utility model relates to a water diversion channel, and more particularly to a water diversion channel with diversion and pressure relief function. Background Technology

[0002] Irrigation canals need to divert water to prevent excessive flow from overflowing the canal and damaging surrounding crops and vegetation. Generally, for irrigation canals with large water flows, multiple branch canals are built on the main canal to alleviate pressure caused by excessive flow. However, existing branch canals often use simple gate structures to control water flow or shut off the flow. This setup is ineffective in regulating flow and, due to the lack of waste filtration and interception mechanisms, waste accumulates at the gates or bends, eventually leading to blockages or obstructions. Therefore, the purpose of this invention is to provide an irrigation canal with diversion and pressure relief functions. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art, namely, the lack of good flow regulation effect and the easy accumulation of garbage at gates or bends, by proposing a water diversion channel with diversion and pressure relief function.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A water diversion channel with diversion and pressure relief function is provided, including a main channel, several branch channels for drainage distributed on both sides of the main channel, several first hydraulic cylinders and several second hydraulic cylinders installed on the top of the side walls of both sides of the main channel, the first hydraulic cylinders being connected to the main channel drainage valve, and the second hydraulic cylinders being connected to the branch channel drainage valves, and further comprising:

[0006] The guide plate and the interception mechanism on the guide plate are used to guide the silt into the drainage branch channel to reduce the silt in the main channel, and to intercept large debris through the interception mechanism.

[0007] As a preferred technical solution of this utility model: a main channel slope is provided on the main channel, and the main channel slope is opened at the front end of the intersection of the main channel and the discharge branch channel. The main channel slope is used to introduce water flow into the discharge branch channel through the slope height difference.

[0008] As a preferred technical solution of this utility model: a main channel depression is provided at the intersection of the main channel and the discharge branch channel, and a silt guide plate is fixedly installed on the surface of the main channel depression. The silt guide plate has a V-shaped structure, and both ends of the silt guide plate are set on the side wall of one end of the discharge branch channel on both sides.

[0009] As a preferred technical solution of this utility model: the main channel discharge valve is set at the intersection of the main channel and the discharge branch channel, the main channel discharge valve is set on the main channel, the main channel discharge valve is T-shaped, the first hydraulic cylinder includes a first piston rod, and the top and bottom ends of the main channel discharge valve are fixedly connected to the first piston rod.

[0010] As a preferred technical solution of this utility model: the branch canal drainage valve is set at the intersection of the main canal and the drainage branch canal, the branch canal drainage valve is set on the drainage branch canal, the branch canal drainage valve is T-shaped, the second hydraulic cylinder includes a second piston rod, and the top and bottom ends of the branch canal drainage valve are fixedly connected to the second piston rod.

[0011] As a preferred technical solution of this utility model: the interception mechanism includes a filter screen disposed at the edge of the guide plate surface, the filter screen being used to block large impurities from passing through.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this type of water diversion channel with diversion and pressure relief function, the main channel discharge valve and the branch channel discharge valve can be opened when the water flow is high, allowing water to flow into the branch channel for diversion and pressure relief.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this embodiment can be combined with each other. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a water diversion channel with diversion and pressure relief function, including a main channel 1, several drainage branch channels 2 distributed on both sides of the main channel 1, several first hydraulic cylinders 4 and several second hydraulic cylinders 7 installed on the top of the side walls on both sides of the main channel 1, the first hydraulic cylinders 4 are connected to the main channel drainage valve 3, and the second hydraulic cylinders 7 are connected to the branch channel drainage valves 6. It also includes: a silt guide plate 103 and an interception mechanism provided on the silt guide plate 103. The silt guide plate 103 is used to guide silt into the drainage branch channels 2 to reduce the silt in the main channel 1, and the interception mechanism intercepts large debris.

[0027] To prevent water flow from stagnating when the water volume is low, a main channel slope 101 is installed on the main channel 1. The main channel slope 101 is located at the front end of the confluence of the main channel 1 and the spillway branch channel 2. The main channel slope 101 is used to guide the water flow more smoothly into the spillway branch channel 2 through the difference in slope height. Utilizing the inertia of water flowing downhill, the water can continue to flow even when the water volume is low, and can enter the spillway branch channel 2 more smoothly when the water in the main channel 1 is abundant.

[0028] At the confluence of the main channel 1 and the branch channel 2, a main channel depression 102 is provided. A guide plate 103 is fixedly installed on the surface of the main channel depression 102. The guide plate 103 has a V-shaped structure design, and both ends of the guide plate 103 are set on the sidewalls of the branch channels 2 on both sides. The interception mechanism includes a filter screen 5 on the surface of the guide plate 103, which is used to block large impurities from passing through.

[0029] It should be added that the filter screen 5 consists of two inclined filter screens located directly in front of the main channel discharge valve 3 and a filter screen located directly in front of each branch channel discharge valve 6. All four filter screens are fixed on the guide plate 103, which can effectively filter out large debris and prevent it from entering the main channel 1 and the discharge branch channel 2 and causing blockage. In addition, the filter screens are in contact with the bottom surface of the main channel 1 to prevent large debris from escaping from the bottom.

[0030] The main channel drain valve 3 is located at the confluence of the main channel 1 and the branch channel 2. The main channel drain valve 3 is T-shaped and its top ends are fixedly connected to the piston rod of the first hydraulic cylinder 4. Similarly, the branch channel drain valve 6 is located at the confluence of the main channel 1 and the branch channel 2. The branch channel drain valve 6 is T-shaped and its top ends are fixedly connected to the piston rod of the second hydraulic cylinder 7. The main channel drain valve 3 is located on the main channel 1, and the branch channel drain valve 6 is located at one end of the branch channel 2. Both the main channel drain valve 3 and the branch channel drain valve 6 are T-shaped and perpendicular to each other. The main channel drain valve 3 is raised and lowered by the first hydraulic cylinder 4 to control the water flow in the main channel 1, while the branch channel drain valve 6 is raised and lowered by the second hydraulic cylinder 7 to control the water flow in the branch channel 2. The water flow can be controlled by adjusting the rise and fall of the main channel discharge valve 3 and the branch channel discharge valve 6. The water flow can be diverted and depressurized according to the actual situation and the required water flow.

[0031] In practical use, water flows through the main channel slope 101 into the main channel depression 102. Silt is guided into the drainage branch channel 2 by the guide plate 103. Large debris such as plastic bags are blocked by the filter screen 5. The remaining water flows through the main channel drainage valve 3 and the branch channel drainage valve 6 into the main channel 1 and the drainage branch channel 2. The main channel drainage valve 3 on the main channel 1 can be adjusted in height by the first hydraulic cylinder 4 to reduce the water flow, or even close the main channel drainage valve 3 to allow the water flow into the drainage branch channel 2. The branch channel drainage valve 6 on the drainage branch channel 2 can be adjusted in height by the second hydraulic cylinder 7 to reduce the water flow, or even close the branch channel drainage valve 6 to allow the water flow into the main channel 1. If water storage is required, closing both the main channel drainage valve 3 and the branch channel drainage valve 6 will achieve the water storage effect.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
