Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a fence for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Rivers and canals in various places bring convenience to people's lives and agricultural irrigation. At present, domestic and industrial garbage, including plastic bottles and garbage bags, often float on the surface of rivers and canals. This not only affects the ecological environment of the river, but also easily pollutes the water source. Therefore, it is necessary to use fences to intercept and clean up floating garbage to prevent it from spreading to a wider area of ​​water and causing greater pollution.

[0003] A patent document with publication number CN219430710U discloses an adjustable hydraulic fence. This adjustable hydraulic fence, through the installation of a connecting plate, allows workers to drive a threaded rod via a motor, enabling the connecting plate to move the fence body up and down, thus adjusting the height of the fence body. This allows the fence body to block debris from the water surface at different water levels. Simultaneously, a passageway exists between the fence body and the frame, allowing aquatic organisms to pass through normally, achieving better usability. However, the length of the fence body is specific, requiring different fence lengths for different river channels, thus limiting the applicability of this adjustable hydraulic fence. Therefore, a hydraulic engineering fence is needed to solve the above problems. Utility Model Content

The position of the adjusting rod 1103 corresponds to that of the first adjusting hole 10, and the size of the adjusting rod 1103 is adapted to the first adjusting hole 10, so that the adjusting rod 1103 can move smoothly and be inserted into the first adjusting hole 10.

[0030] A type of hydraulic engineering fence operates on the following principle:

[0031] 1) Move the second adjusting slide plate 304 out of the inside of the second adjusting slide groove 303. At this time, the first fence frame 2 drives the first fence net 4 to move and adjust the first fence net 4 to a suitable height according to the depth of the river.

[0032] 2) Connect the adjusting bolt 302 to the second adjusting hole 305 at a suitable height, thereby fixing the first fence 4 at a suitable height;

[0033] 3) Pull the movable block 1102 to move the adjusting rod 1103 away from the support frame 5. At this time, the fixed spring 1101 is in a stretched state.

[0034] 4) Move the second fence frame 8 to drive the first adjusting slide plate 7 to move, adjust the second fence frame 8 to a suitable position according to the width of the river channel, and make the adjusting rod 1103 correspond to the position of the first adjusting hole 10 at the appropriate position.

[0035] 5) Loosen the movable block 1102, and under the reaction force of the fixed spring 1101, the adjusting rod 1103 is inserted into the first adjusting hole 10, thereby fixing the second fence frame 8 at a suitable height. At this time, the operation of blocking garbage can be carried out through the water conservancy project fence.
