Description

Technical Field

[0001] The utility model relates to the field of gates, in particular to a river overflow gate. Background Art

[0002] A gate, also known as a gate or sluice gate, is a hydraulic engineering facility used to control water levels.

[0003] In the process of promoting ecological civilization construction, environmental protection and governance of river waters are indispensable. At present, garbage and pollutants in rivers often become one of the main problems affecting water quality and ecological balance. Traditional gate structures play an important role in regulating water flow and flood prevention and disaster relief, but they have certain limitations in intercepting garbage. Garbage drifting with the water flow will float near the gate because the gate is closed. At this time, manual cleaning of the garbage floating on the water surface is required, which is not only time-consuming and labor-intensive, but also inefficient. If the gate is opened directly to release water without cleaning the garbage, the garbage will continue to drift along the river channel, destroying the river environment.

[0004] The prior art (authorization announcement number CN220977913U, application date 2024.04.16) discloses a sluice with a garbage interception mechanism for a river. The technical solution intercepts garbage by setting an interception plate on the gate mounting frame, and then drives the fixed plate to move upward to bring out the garbage from the river, thereby replacing manual garbage cleaning and improving work efficiency. However, since the relevant garbage interception mechanisms are all arranged on one side of the gate mounting frame, and the garbage collected on the fixed plate during operation also has a certain weight, this will cause uneven force on both sides of the gate mounting frame, especially for small gate mounting frames, there is a risk of tilting and collapse. Utility Model Content

[0005] The purpose of the embodiment of the present application is to provide a river overflow gate to solve the problem that the existing garbage interception mechanism is arranged on one side of the gate installation frame, and the garbage collected on the fixed plate during operation also has a certain weight, resulting in uneven force on both sides of the gate installation frame, which easily causes the small gate installation frame to tilt and collapse. The specific technical solution is as follows:

[0006] In a first aspect of an embodiment of the present application, a river overflow gate comprises a frame and a gate, wherein the gate is slidably connected to the frame, the frame is provided with a driving mechanism for driving the gate to slide, the bottom of the end surface of the frame is connected with a first embedded part protruding outward, the bottom surface of the frame is connected with a second embedded part protruding outward, and also comprises an intercepting part, which is slidably connected to the end surface of the frame, the intercepting part is provided with a water level sensor, and the water level sensor is signal-connected to the driving mechanism.

[0007] In some embodiments, the first embedded part is perpendicular to the front end surface or the rear end surface of the frame, the second embedded part is perpendicular to the bottom surface of the frame, the number of the second embedded parts is two, and the two second embedded parts are spaced and symmetrically arranged.

[0008] In some embodiments, a plurality of horizontal bars and vertical bars are provided on the gate, and a plurality of the horizontal bars and a plurality of the vertical bars are arranged alternately and separate a plurality of squares on the gate.

[0009] In some embodiments, the top of the gate is provided with an overflow port penetrating the front end face and the rear end face thereof, and the overflow port is arranged in the grid.

[0010] In some embodiments, the intercepting portion includes a fence member and two guide rods, the two guide rods are symmetrically connected to the two ends of the fence member, and the frame is provided with a slide groove for installing the guide rods.

[0011] In some embodiments, a lifting mechanism is also included, which is connected to the frame. The lifting mechanism includes a motor and a fixed pulley. The motor is connected to the fixed pulley, and the motor is connected to the water level sensor signal. A rope is wrapped around the fixed pulley, and the end of the rope extends into the slide groove and is connected to the guide rod.

[0012] In some embodiments, the fence member includes a first fence and a second fence, and the first fence is arranged perpendicular to the second fence.

[0013] Beneficial effects of the embodiments of the present application: This technical solution allows the frame to be installed more firmly and stably in the river channel by arranging the first embedded parts and the second embedded parts on the frame. The gate can also be automatically opened or closed according to the water level. Compared with the current technology, the structure of the interception part is simplified, which ensures that the garbage can be intercepted while reducing its impact on the main body of the frame.

[0014] Additional aspects and advantages of the present invention will be partially given in the following description, and partially will become apparent from the following description, or will be understood through the practice of the present invention. Of course, it is not necessary to achieve all of the advantages described above at the same time for any product or method to be implemented in this application. BRIEF DESCRIPTION OF THE DRAWINGS
