Abstract

This invention relates to the protection of waters and is intended to reduce oxygen deficiency. The aim of the invention is to facilitate the operation of the device by automating the movement of the piston and increasing the operational reliability. The device contains a cylinder 1 suspended on the truck 5 with a movable piston 2 along its axis provided with struts 7 and a screen 3. In the lower part of the cylinder there is a lock in the form of pins 8 actuated by a float 18 fixed to the cylinder 1 coaxially on its surface. When the device is lowered into the reservoir, the upper layers of water are poured into the cylinder 1. After the cylinder is lowered, when the screen 3 contacts the bottom of the ground, the piston 2 rises up and displaces the water of the upper layers. At the same time, the space under the piston 2 is filled with water from the bottom layers. Next, the fingers 8 fix the upper position of the piston 2 and the device is raised to the surface, after which the piston with the float 18 when the cable 17 is loosened is removed from the fixation and lowered down, pushing out the bottom layers of water. The invention makes it possible to exclude the use of an additional mechanism for raising and lowering the piston. 4 il.

Description

 The invention relates to the protection of waters from pollution and is intended for. reducing oxygen deficiency and improving the ecological state of predominantly deep water bodies and streams

The aim of the invention is to facilitate reliable operation of the device by automating the movement of the piston and increasing reliability in operation.

Fig. 1 shows the proposed device in two positions - upper and lower, a general view; Fig, 2 - cylinder, longitudinal section; in fig. 3 is a section A-A in FIG. 2; FIG. 4 is a cross-section of BI — FIG. 3,

The device comprises a vertical cylinder 1 with a piston 2 and a screen 3, the cylinder 1 is suspended on the winch 4 of the truck 5, the piston 2 is provided with a sealing rubber cuff 6 and is mounted with the possibility of vertical movement. To the lower part of the piston 2 along its perimeter, the guides are fastened in the form of struts 7 connected to the screen 3, the screen 3 is made perforated,

In the lower part of cylinder 1 piston clamps 2 are installed in the form of radially mounted pins 8 equipped with a compression spring 9 placed between an annular abutment 10 fixed to a finger 10 and a corner shelf 11 Fingers 8 are placed between walls 12 of guide posts

7, Racks 7 are provided with holes 13 corresponding to the profile of the fingers.

8. Between the wall of the cylinder 1 and the ring stop 10 a wedge 14 is placed in the form of a fork, between the ends of which a finger 8 is placed.

The wedge 14 is provided with a compression spring 15 placed between its upper part and the console 16 of the cylinder 1, a flexible gasket 17 is attached to the wedge 14, connected to the other end with an annular float 18 placed coaxially with the cylinder 1 ti.

In the upper part of the uprights 7, the limiter 19 is strengthened, and in the lower part of the cylinder - an emphasis 20. The upper part of the cylinder 1 is provided with windows 21, d The device operates as follows.

Using the winch 4 of the truck 5, the device is lowered into the water until the windows 21 coincide. with the top layer of water. The piston 2 is in its lower position at this time, the stop 19 is in contact with the stop 20,

The float 18 lies on the water surface Q, the cable 17 is not pulled, the wedge 14 with the help of the spring 15 through the ring stop 10 holds the pin 8 between the walls 2 of the uprights 7.

After the water has been completed, the cylinder 1c is lowered by the winch 4 to the bottom of the reservoir. At the moment of lowering the cylinder, the float 18 pulls the cable 17, which partially pulls the click 14, while pressing the spring 15, the spring 9 through the ring stop 10 acts on the finger 8. And presses it to the rack 7. When the screen 3 stops in the ground cylinder 1 it continues to descend, and water accumulated in the cylinder from the upper layers is replaced by porgan 2. At the same time,

Yes, the bottom layer fills the space under the piston. The fingers 8, when coinciding with the hole 13, enter into this hole under the action of the spring 9,

which ensures that the piston 2 is locked in the upper position.

Winch 4 raise the device to the upper position and partially raise above the surface of the water. The float 18, while remaining on the surface of the water, weakens the pull 17 and the wedge 14 descends under the action of the spring 15 and leads the pin 8 out of the opening 13 of the stand 7. This ensures that the piston 2 is removed from fixation.

The upper layers of water through the windows 21 are poured into the cylinder 1, and the piston 2 is lowered under the action of its mass, simultaneously pushing the water out of the bottom layer.

Next, the device is again lowered to the bottom, and the process is repeated.

The invention makes it possible to exclude the use of an additional mechanism for raising and lowering the piston.
