Problems solved by technology

[0004] When diverting water for irrigation, it is necessary to cooperate with small gates to manage water flow, and there are generally many impurities in the water source. If they are not screened out, many of the impurities will affect irrigation, but in conventional technology, they are all on the gate. Install a filter structure, because the filter structure is too fine when the water flows through it is not suitable
The filter screen will accumulate impurities when the water flows through, and under the impact of the water flow, the filtered impurities will adhere to the larger and blocked filter screen area, which will affect the delivery of the water flow, requiring frequent filter cleaning, manpower and material resources Consumption is larger

Embodiment 1

[0022] see figure 1 , in an embodiment of the present invention, a miscellaneous filtering and anti-clogging gate of a water conservancy project includes a gate body 1. The gate body 1 is a trapezoidal concrete pouring structure. It has a filter structure with different mesh sizes. When the water flow passes through, it can isolate the impurities in the water body, so that the water after passing through can be effectively applied in water conservancy irrigation.

[0023] Both sides of the upper end of the gate body 1 are symmetrically provided with brackets 7. The brackets 7 can be formed by concrete pouring or fixed by steel structures. The opposite sides of the brackets 7 are symmetrically embedded and vertically embedded with sliding grooves. The sliding grooves The inner sliding fit is provided with a sliding horizontal plate 10, and the lower end of the sliding horizontal plate 10 is provided with a sealing structure through welding or integral molding; the upper end of ...

Embodiment 2

[0025] see Figure 2~3 , in the embodiment of the present invention, a water conservancy project filter anti-clogging sluice, on the basis of embodiment 1, when the impurities in the water flow pass through the filter structure, the water flow will be frequently blocked due to adhesion, which requires frequent cleaning Impurities consume too much manpower and material resources, so on the basis of Example 1, the filter structure includes a coarse filter 2 and a fine filter 3 assembled on the front and rear openings of the gate body 1, and the two sides of the gate body 1 are also A partition 4 is arranged symmetrically. The front and rear sides of the partition 4 block the two sides of the gate body 1 to form a cavity. The assembly is provided with a blocking structure, and the blocking structure includes a gate plate 6 , which slides through the upper end of the gate body 1 and is fixedly connected with the lower end of the sliding horizontal plate 10 .

Abstract

The invention discloses an impurity filtering and anti-blocking gate of water conservancy project. The impurity filtering and anti-blocking gate comprises a brake body, the lower part of a gate body communicates front and back, filtering structures with different mesh sizes are correspondingly embedded in front and back openings, supports are symmetrically arranged on the two sides of the upper end of the gate body, sliding transverse plates driven by a hydraulic telescopic rod are slidablyarranged on the supports, blocking structures are arranged at the lower ends of the sliding transverse plates, and the gate body is further internally provided with a synchronously rotated driving structure and a dredging structure for blockage prevention. According to the impurity filtering and anti-blocking gate, the water flow impacts blades to drive a first rotating shaft and a second rotating shaft to rotate synchronously, and spiral fan blades on the two sides are driven to convey materials inthe opposite directions, when residual fine impurities in the water flow are intercepted by a fine filter screen after being filtered by a coarse filter screen, increased impurities can be evacuated to the two sides or concentrated to the middle when the spiral fan blades rotates, the impurities can be prevented from covering the side surface of the fine filter screen in a large area, thus the effective passage of the water flow for a long time can be ensured, and the impurities are convenient to maintain and process centrally.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a miscellaneous filtering and anti-clogging sluice for water conservancy engineering. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. [0003] The gate is used to close and open the control facility of the discharge (discharging) channel. It is an important part of the hydraulic structure and can be used to intercept the water flow, control the water level, adjust the flow, discharge sediment and floating objects, etc. [0004] When diverting water for irrigation, it is necessary to cooperate with small gates to ...
