Description

Turnover fence for hydraulic engineering

Technical Field

The utility model relates to a fence for hydraulic engineering, concretely relates to convertible fence for hydraulic engineering.

Background

The hydraulic engineering generally has the problem of floaters, and a large amount of floaters are easy to gather in front of a river channel bank and a river blocking dam along the river, so that the adverse effects on water quality along the river, water surface landscape, water supply, aquatic products, shipping and the like are formed, the power generation benefit of a hydroelectric hub is reduced, and the operation safety of the hub is threatened. Fence type trash rack and square grid type trash rack commonly used in the prior art intercept floaters, but accumulated day by day and month, the floaters are easily accumulated in front of the trash rack, normal drainage of hydraulic engineering is influenced, and when the trash is cleaned, time and labor are wasted and efficiency is low due to the fact that water bodies and water depth is caused during manual fishing.

In order to prevent floaters from blocking the fence and influencing drainage in the prior art, structures of grid gaps of adjustable trash racks are designed, if the application number is CN201720866852.8, the published date is 2018, 03, 27, the name of the Chinese utility model is 'a prevent blocking type trash rack for hydraulic engineering', and the technical scheme is as follows: the utility model provides a prevent blocking formula trash rack for hydraulic engineering, includes supporting frame and telescopic bolt, supporting frame internally mounted has first recess seat, the both sides of cross slab all are fixed with the second recess seat, the top center department of supporting frame installs indisputable link, and the both sides of supporting frame are connected with waterproof gear telescopic link, waterproof gear telescopic link one end is fixed with the iron clamp plate. Because be connected with the bars between first recess seat and the second recess seat, make the recess that the both ends of bars can be in first recess seat and second recess seat remove the regulation to change the distance between the bars, according to the speed of rivers, select suitable bars interval, avoid the trash rack to take place the phenomenon of jam, the supporting frame passes through threaded connection with telescopic bolt, and telescopic bolt's one end is connected with first recess seat, rotate telescopic bolt and can carry out the downstream with first recess seat, realize fixing the bars.

Above-mentioned patent prevents through the grid clearance of adjusting the trash rack that floating garbage blocks up, nevertheless adjusts and wastes time and energy to it is inconvenient, and the salvage degree of difficulty of floater is high, salvage inefficiency, has increased artifical intensity of labour on the contrary.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving among the prior art floating garbage and be difficult for the clearance, and make the trash rack take place to block up easily, influence hydraulic engineering normal drainage scheduling problem, provide a hydraulic engineering uses convertible fence, the device closes the different fence collection of two kinds of structures as an organic wholes, changes the clearance of fence through the upset fence to satisfy the user to daily trash or the demand of normal drainage, still can make things convenient for floating garbage's clearance before the grid.
