Description

 The invention relates to the operation and maintenance of water bodies and can be used to clean them from humoid formations, including sapropel.

 A device for suctioning material from the bottom of rivers, canals and other bodies of water, comprising a float with a suction pump, to which a suction pipe is connected with a device in the form of a box, preventing large objects from entering the suction system [1].

 Disadvantages: high energy consumption of the pump for continuous suction, unreliability in the operation of the suction system.

 A device is known with a vacuum grip for the development of viscous soils, containing a vertical cylindrical body, open from the bottom, with a loading and unloading confuser and equipped with a vacuum and outlet. The vacuum hole is connected by a hose to a vacuum source - a screw pump [2].

 The disadvantages of the prototype: the high energy consumption of the pump for continuous suction, the unreliability of the extended vacuum system.

 The purpose of the invention is to reduce energy consumption and increase reliability in operation.

 This is achieved by the fact that in the device containing the intake working element of the suction type with the pump unit, the moving body of the intake body and the drive, the pump unit is made in the form of a chamber separated by a partition, in the center of which a pipe is mounted with a torus installed inside it and a sleeve passed through the torus , the ends of which are inverted and fixed along the perimeter of the inner walls of the chamber on both sides of the partition with the formation of cavities communicated using hoses with a supply and outlet system for the working agent. In each compartment of the chamber, suction and discharge openings are provided with valves. The intake element is fixed at the end of the moving sleeve and is connected by a cable to a reversibly rotating drive drum installed in a sealed chamber in communication with the working agent supply system. In the same chamber, the end of the moving sleeve is fixed.

 By alternately supplying and discharging the working agent, the volume of the cavities in the chamber sections is increased or decreased, creating in them alternately a vacuum that promotes the intake of sapropel, or overpressure displacing the sapropel into the discharge organ.

 The drawing schematically shows a General view of the proposed device.

 It contains a sealed chamber 1 in communication with the system 2 for supplying and discharging a working agent (gas). A drive drum 3 is installed in the chamber 1 with a cable 4 wound on it, which is passed through a sleeve 5, one end of which is fixed in the chamber 1 and the other is attached to the pipe 6 in communication with the intake chamber 7. The cable 4 is attached to the pipe 6. In the intake a sleeve 8 is located in the chamber 7, passed through a torus 9 installed in the pipe 10. The opposite ends of the sleeve 8 are turned out and fixed around the perimeter of the inner wall of the chamber 7 with the formation of cavities 11 and 12, separated by a partition 13 and separately communicated by hoses 14 with the supply and exhaust system 2 workman agent (gas). On both sides of the partition 13 in the intake chamber 7 there are made suction holes 15 and outlet holes 16 in communication with the outlet pipe 17 and provided with valves.

 The device operates as follows. By transport, the device is moved with the compressor to the place of development. After moving it to the development site by system 2, a working agent (gas) is fed into the sealed chamber 1 and through it into the sleeve 5, the straightening sleeve 5 and with its help moving the intake chamber 7 to the place of extraction of sapropel. One of the hoses 14 delivers a working agent (gas) into the cavity 11, it increases in volume by pulling the sleeve 8 through the torus 9 and the pipe 10 and, accordingly, reducing the cavity 12 in the volume. As a result, in the part of the chamber in which the cavity 12 formed by the sleeve 8 is located, a vacuum is formed, due to which sapropel enters through the suction hole 15. Then, the supply of the working agent is switched to the cavity 12. It begins to increase in volume by reducing the cavity 11 by pulling the sleeve 8 through the torus 9 and the pipe 10. In this case, the working agent from the cavity 11 either returns to the system 2 or is bled. The part of the sleeve 8, which forms the cavity 12 together with the partition 13, overlaps the suction hole 15, through which the sapropel entered in the first half of the cycle, and fills the corresponding part of the chamber 7, displacing the previously taken sapropel through the outlet valve 16 opened by overpressure into the outlet pipe 17. At this time, in the other half of the chamber 7, a decrease in the cavity 11 creates a vacuum, due to which sapropel enters through the suction hole 15 located in this half of the chamber 7. Then, the supply of the working agent again switches to the cavity 11, it increases in volume, decreasing the volume of the cavity 12, from which the working agent is either either diverted to the system 2 or bleed. At the same time, from the part of the chamber 7, where the cavity 11 is located, the sapropel is forced out, and in the opposite there is its fence. Thus, the cycles alternate until the sapropel is fully developed in this place. After this, by rotating the drive drum 2 with a cable 3, the nozzle 6 is pulled and with it the intake chamber 7 to the sealed chamber 1, the sleeve 5 is folded. Then, by supplying the working agent to the sleeve 5, it is sent to another place of sapropel production, where the work cycles are carried out in the manner described above.

 Using the proposed device allows to reduce energy consumption for moving the intake body and for sapropel intake, spent mainly on the supply of the working agent (gas), to increase productivity due to the alternate operation of the half-chambers and the pump located in them, to reduce the dimensions by 5-10 times.
