Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, and particularly relates to a diversion and intercepting device for a river course. Background Art

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, also known as a water project. During the water conservancy construction process, the interception method is often used to block the water flow so that it no longer flows to the construction site, providing guarantee for water conservancy construction.

[0003] Chinese Patent with the patent number CN214993608U discloses a river course intercepting device for water conservancy construction. A fastening plate is fixedly connected between the first support and the second support. A controller is fixedly connected to the edge of the upper surface of the fastening plate, and an adjusting mechanism is also installed on the fastening plate. A receiving groove is formed at the top of the support seat, and a placing groove communicated with the receiving groove is formed inside the support seat. A sealing mechanism is installed inside the placing groove and the receiving groove, and a storage battery is fixedly connected to the inner corner of the placing groove. The height of the gate plate can be adjusted as needed through the adjusting mechanism, so as to facilitate the drainage and interception of the river water in front of the gate plate. Moreover, the gate plate is lifted and lowered by means of mechanical transmission, which is not only time-saving and labor-saving, but also can significantly improve the interception efficiency. The sealing mechanism can seal between the gate plate and the support seat to prevent river water leakage caused by gaps between the gate plate and the support seat.

[0004] Although the above-mentioned river course intercepting device can block the river course during use to ensure the normal progress of the water conservancy construction process, during the process of blocking the river course, on the one hand, since the above-structured river course intercepting device cannot timely divert the water blocked upstream of the river course, it is easy for the device to be flooded by the excessive accumulation of water upstream of the river course after blocking, resulting in water overflowing the river course and causing flood disasters. On the other hand, since the above-structured river course intercepting device cannot prevent the sundries in the river course from entering the blocking space of the gate plate during use, the gate plate is easily affected by the sundries in the river course during the actual blocking process and cannot quickly intercept and block the river course, and the interception and blocking efficiency is relatively low. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a diversion and intercepting device for a river course that can not only timely divert and drain the water upstream of the river course after interception and blocking without affecting the normal progress of the water conservancy construction process, but also effectively prevent the sundries in the river course from entering the blocking space during the interception and blocking process according to the current situation of the prior art.

[0006] The present utility model is realized through the following technical solutions: The present utility model provides a diversion and interception device for a river course, which includes a support base. On both sides of the upper end of the support base, two storage grooves are symmetrically opened. In each storage groove, a diversion gate is installed.

In the middle of the upper end of the support base, an interception groove is also opened. On both sides of the interception groove, two filter net plates are symmetrically installed. In the middle of the interception groove, an interception gate is installed.

At the same time, by controlling the height of the diversion gate in the storage groove, the opening size of the diversion channel can be adjusted, so that the water accumulated upstream of the river course after blocking can be discharged through an external pipeline around the water conservancy construction site on the river course through the diversion pipe, avoiding excessive accumulation of water upstream of the river course after blocking and preventing the river water from overflowing the river course and causing flood disasters.

[0008] Further, in the middle of the upper end of the interception gate, an electric hydraulic rod one is installed. On both sides of the upper end of the support base, a bracket is jointly installed.

[0009] By adopting the above technical solutions, the electric hydraulic rod one is mainly used to realize the lifting of the interception gate, so as to quickly block the river course according to actual interception and blocking needs.

[0011] By adopting the above technical solutions, it can be ensured that the interception gate is synchronously lifted and lowered with the electric hydraulic rod one.

[0012] Further, a sealing gasket one is installed on the outer wall of the interception gate through bolts, and a sealing gasket two is installed on the outer wall of the diversion gate through bolts.

[0013] By adopting the above technical solutions, the sealing gasket one can effectively increase the sealing performance of the interception gate during blocking, and the sealing gasket two can effectively increase the sealing performance of the diversion gate when it is closed.

[0014] Further, the fixed part of the electric hydraulic rod two is bolted to the bracket, and the telescopic part of the electric hydraulic rod two is bolted to the diversion gate.

[0015] By adopting the above technical solution, the second electric hydraulic rod is mainly used to realize the lifting adjustment of the diversion gate plate so as to block the diversion channel according to actual usage requirements.

[0016] Furthermore, the diversion pipe is bolted to the support seat, and the diversion pipe is of a bent structure.

[0017] By adopting the above technical solution, the diversion pipe can be connected to an external diversion pipeline to drain the water upstream of the river channel after blocking around the water conservancy project construction site, avoiding excessive accumulation of water upstream of the river channel.

[0018] Furthermore, the filter cover is bolted to the support seat. The middle part of the filter cover is of a porous structure, and the periphery of the filter cover is of a solid border structure.

[0019] By adopting the above technical solution, the filter cover can effectively prevent sundries in the river channel from entering the diversion channel during diversion, avoiding blockage of the diversion channel.

[0020] Furthermore, a storage battery is also installed on one side wall of the bracket by bolts, and an operation panel is also installed below the storage battery on the bracket.

[0023] Through the design of the second electric hydraulic rod, the diversion gate plate, the diversion channel, the filter cover and the diversion pipe, after the river channel diversion and interception device intercepts and blocks the river channel, the water accumulated upstream of the river channel after blocking can be drained around the water conservancy construction site on the river channel through the diversion channel and the diversion pipe via an external pipeline, effectively avoiding excessive accumulation of water upstream of the blocked river channel, preventing river water from overflowing the river channel and causing flood disasters. At the same time, by installing a filter net plate on both sides in the interception groove respectively, the device can effectively prevent sundries in the river channel from entering the lower space of the interception gate plate when intercepting and blocking the river channel, thereby effectively improving the interception and blocking efficiency of the device for the river channel.
