Description

Fishway semi-submersible type float blocking device

Technical Field

The utility model relates to a device for cleaning floating garbage in a river channel, in particular to a fishway semi-submersible type float blocking device.

Background

A plurality of fishway outlets are generally arranged at the upstream position of a reservoir area float retaining device in a dam type hydropower station adopting a vertical seam type fishway. In order to prevent garbage in a reservoir area from entering a fishway, blocking a vertical seam, damaging fish monitoring facilities and influencing the video observation effect, the arrangement of the special float blocking device for the fishway is necessary. However, the general float blocking device generally floats on the water surface, gaps among floating balls (buoys) are large, small garbage can still pass through the gaps, the float blocking depth cannot be adjusted, and garbage such as wood with large specific gravity can pass through the gaps below the float blocking cables and enter a fishway. The garbage entering the fishway can block the vertical seam, damage the monitoring equipment and trigger the fishway counting device by mistake, so that the counting is not accurate, and therefore, the general float blocking device cannot meet the requirements of fish passing and effect observation on float blocking of the fishway.

In addition, the Chinese patent publication No. CN106192957A discloses a river floating garbage cleaning device, which comprises a blocking net, a scraping net and two sliding rods which are arranged in parallel, wherein the blocking net is transversely intercepted and arranged in a river, and the upper side of the blocking net is positioned above the water surface of the river; the slide bar spanes the river and sets up the one side of intaking at the block net, scrape the net limit along being provided with the sliding sleeve of slide bar adaptation, the sliding sleeve cover is established on two slide bars, scrapes the upper side and is located more than the rivers surface of river, the slide bar both ends are provided with the carousel respectively, still include closed loop haulage rope, and the haulage rope is around on two carousels, the haulage rope with the sliding sleeve is connected. The blocking net can block floating garbage brought by floating flowing water, the scraping net can transversely move along the sliding rod, and garbage accumulated on the water inlet side of the blocking net is scraped to the edge and is intensively cleaned. The above patent still has the defect that small garbage still has the possibility of passing through the gap, the depth of the float block cannot be adjusted, and garbage such as wood with large specific gravity can pass through the gap below the float block cable and enter the fishway.

Furthermore, the buoy support is connected with a sliding ring through a traction rope, and the sliding ring is connected with a lifting device through the traction rope. The pulling rope is connected with the slip ring through the line card.

Furthermore, the upper part of the upright post is provided with a fixed pulley, and the traction rope is connected with the lifting device by bypassing the fixed pulley. The lower part of the upright post is provided with a limiting block for preventing the float blocking device from sinking into the river bottom.

Furthermore, gaps between a plurality of buoys are 2-5 cm. The balancing weight is a concrete block, can be prefabricated with balancing weights of different weights and can be adjusted at any time according to needs.

The utility model has the following advantages:

the utility model provides a semi-submersible type float blocking device for a fishway outlet of a power station reservoir, the blocking depth is adjustable, the maximum depth can be as high as that of a steel pipe support, small garbage and semi-submerged garbage with high specific gravity can be blocked, the fishway is prevented from being blocked, the safety of fishway underwater monitoring facilities and the fish passing monitoring effect are ensured, the structure is simple and reliable, and the maintenance is convenient.
