[0002] Water conservancy projects typically include reservoirs, dams, hydropower stations, irrigation systems, and flood control projects. Water conservancy construction refers to the activities carried out during the construction process, following design requirements and construction specifications. Detailed geological surveys and environmental assessments are required before construction begins. During construction, river diversion is necessary, which may include excavation, drainage, and grouting. Furthermore, the foundations in the construction area must be reinforced and treated to ensure project stability.

[0030] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediary, and connections within two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0031] Refer to the attached Figure 1-3 , a water-stopping device for water conservancy project construction, comprising:

[0032] Two support frames 1 are symmetrically arranged; a guide groove 2 is opened on the inner side of the support frame 1, and a lifting device 3 is provided on the top thereof; the lifting device 3 can adopt existing technologies such as a solution of a drive motor cooperating with a gear and a rack, or a solution such as a cylinder or a steel rope lifting to realize the lifting and lowering of the gate plate 6; a water-stop bottom plate 4 is provided at the bottom of the two support frames 1, and a water-stop groove 5 is opened on the water-stop bottom plate 4;

[0033] The gate plate 6 is located between the two support frames 1, with both sides entering the guide grooves 2 at corresponding positions and connected to the lifting device 3, which drives the gate plate 6 to rise or fall;

[0034] The drive assembly is located above the gate plate 6 and includes a motor 7, a bearing seat 8, and a threaded rod 9. One end of the threaded rod 9 is connected to the output shaft of the motor 7, and the other end is rotatably connected to the bearing seat 8. A slide 10 is also provided on the threaded rod 9, and the bottom of the slide 10 contacts the top of the gate plate 6 through multiple rollers 11.

[0035] The cleaning rod 12 is arranged in front of the gate plate 6, and its top is connected to the slide 10 through a connecting plate; the cleaning rod 12 includes a first rod 13, a second rod 14 and a third rod 15; the first rod 13 is arranged vertically, and its bottom is hinged to the top of the second rod 14; the second rod 14 is arranged at an angle, and its bottom is hinged to the third rod 15; the third rod 15 is arranged at an angle, and its bottom is connected to a cleaning plate 16; the cleaning plate 16 is located in the water stop groove 5.

[0036] In this embodiment, two cleaning rods 12 are symmetrically arranged; the connecting plate includes a connecting horizontal plate 17 and a connecting vertical plate 18; the two sides of the connecting horizontal plate 17 are welded and fixed to the first rod members 13 of the two cleaning rods 12; the upper half of the connecting vertical plate 18 is locked to the slide 10 by a nut 21, and its lower half is locked to the connecting horizontal plate 17 by a nut 21. When the slide 10 slides along the threaded rod 9 under the drive of the motor 7, the two cleaning rods 12 can be driven to move synchronously through the connecting plate, which is convenient for cleaning the waste in the water stop groove 5. A plurality of screw holes are provided on the connecting vertical plate 18; a plurality of limit screws 20 are provided on the slide 10 and the connecting horizontal plate 17, which pass through the screw holes at the corresponding positions and are locked by nuts 21. After loosening all the nuts 21, the connecting vertical plate 18 can be separated from the connecting horizontal plate 17 and the slide 10, which is convenient for disassembly, replacement and maintenance.

[0037] It should be noted that a water baffle 19 is provided between the two cleaning rods 12, and its two ends are connected to the third rods 15 located on either side of it. As the gate plate 6 falls, the water baffle 19 comes into contact with the water flow and is impacted by the water flow, further driving the third rods 15 of the two cleaning rods 12 toward the bottom of the gate plate 6, allowing the cleaning plate 16 connected below the third rods 15 to smoothly enter the water stop groove 5.

[0038] A vertical fixing rod 22 is provided at the front end of the cleaning plate 16; the bottom of the fixing rod 22 is welded to the cleaning plate 16, and the top is welded to the third rod 15. The fixing rod 22, the cleaning plate 16, and the third rod 15 of the cleaning rod 12 form a triangular area, which can enhance the ability to resist water impact and avoid the situation where the components fall apart. Figure 3 It can be seen that the fixed rod 22, the cleaning plate 16 and the third rod 15 of the cleaning rod 12 all adopt a double-layer structure. The positions of the corners of the triangular area are connected by cylinders, which can reduce the pressure of the frontal impact of the water flow, and also facilitate the discharge of waste during the cleaning process of the water stop groove 5.

[0039] In addition, a notch 23 is provided at each end and in the middle of the front wall of the water stop 5, and a notch 23 is provided at each end of the rear wall. The notches 23 correspond to the positions of the cleaning plate 16, facilitating the discharge of waste and the removal of the cleaning plate 16 from the water stop 5 through the notches 23, thereby preventing the gate plate 6 from falling into the water stop 5. Limiting grooves 24 are provided at both ends and in the middle of the bottom of the gate plate 6, with rollers 25 disposed within the limiting grooves 24. The rollers 25 engage with the third rod 15, facilitating the rapid removal of the third rod 15 of the cleaning rod 12 from the notch 23 when the gate plate 6 falls. This also reduces friction loss and helps extend the service life of the third rod 15.

[0040] It should be noted that anti-collision strips 26 corresponding to the position of the first rod 13 are provided on both sides of the gate plate 6, which can avoid the friction loss caused by direct contact between the various components of the cleaning rod 12 and the support frame 1. At the same time, it can ensure that when the cleaning rod 12 moves to both ends, the third rod 15 can just cooperate with the roller 25 at the bottom of the gate plate 6, making it convenient to move the cleaning plate 16 out from under the gate plate 6.

[0041] The utility model of the water-stopping device for water conservancy project construction can push the garbage and waste remaining inside the water-stopping groove 5 and finally flush them away with the water flow from the notches 23 at both ends, while avoiding the underwater operation of the motor 7 and the threaded rod 9, and circumventing some risks of underwater operation of the motor 7 and the threaded rod 9, which is conducive to improving the cleaning efficiency, is very practical, and has good market application prospects.

[0042] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the present invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the present invention and various options and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
