SU1017769A1 - Fish protecting device of water intake - Google Patents

Description

The invention relates to hydraulic engineering and can be used to protect fish from falling into aquatic zabrr. Known fish protection device includes a cap, placed on non-residential area of the reservoir tU. However, such a device is in most cases insufficiently effective, since in water bodies there are practically no zones that are stable in time and space, i containing fish. It is also known that a fish intake water intake device includes a body of a water intake path mounted on a water intake head with a fish collecting basin connected by a fish diverter G. The disadvantage of this device is the possibility of clogging the cone grid and the failure of the washing device, as well as in the death of the fish. . The purpose of the invention is to increase the efficiency of fish protection and reliable operation. The goal is achieved by ensuring that the protective intake device is provided with knee-shaped conduits, one end of which is installed in the hull and provided with a partition that has a two-way conduit, and the external tract is connected from the fish basin to the pool, and the inner one from the hull; The hull is pivotally mounted on the water intake head. FIG. 1 shows a fish intake device for water intake, axonometric in FIG. 2 is the same; a view of Kyy in FIG. 3 is a section A-A in FIG. 2 in FIG. 4 - section bb in figure 3 | in fig. 5 shows a section B-B in FIG. 4; FIG. 6 shows a section Y-D; FIG. 4a FIG. 7 is a section d-d in fig. 4} in FIG. 8 - section E-E in FIG. 4, in FIG. an embodiment of a water intake with several water intakes in FIG. 10 is a variant of making the water intake Q with several intake tips, and the hull - round. water source 1 is connected by an inlet duct 2 by intake pipe-3, which has a shutter 4./ On the tip of the pipeline 3, body 5 is hingedly fixed, having a group of elbows 6 with partitions 7, each I and 6 with two paths, the outer one connected to the fish collecting basin 8, and the internal to the water line 9. The fish collecting basin 8 is connected to the fish removal conduit 10 to the water source 1 in the zoya remote from the water intake, and the water line 9 is connected to the water intake pipe 3. The housing 5 is installed at the free end on supports 11 by means of locks 12. The knee-shaped conduits 6 are interconnected by trusses 13, providing rigidity to the structure. The intake device can be made with two or more water intake pipelines 3, and correspondingly / and cases 5 (Fig. 9 and 107, and the case can be made round in plan (Fig. 107. Depending on the height of the device in the water source 1 C, at a depth or on the surface, housing 5 and conduits could be made in videtrub or trays.The device works in the following way ... Thanks to the hinged fastening of housing 5 on the tip of pipeline 3, it can be installed in water source 1 at any depth. enters the knee-shaped waterways b, where the fish moves to the outer wall of the water supply system 6, and the fish enters through the external path into the fish and water amphibian ... 8 and then through the fish diversion conduit 10 to the water source 1, and the water goes through water conduit 9, water intake pipe 3 enters the discharge channel 2 and further to the consumer. The proposed implementation of the device makes it possible to increase the reliability of its operation, significantly reducing the cost of the fish protection structure, making it possible for devices not only to be used in construction, but also and existing water intakes.
