The invention is illustrated by a specific example of a continuous vacuum pump and compressor unit, which, however, is not the only possible, but clearly demonstrates the possibility of achieving this set of essential features of a given technical result.

According to the invention, a continuous mobile vacuum pump and compressor unit contains at least one main container 21 and three additional containers located on the vehicle 75, wherein, as the first, second and third additional containers, a submersible projectile 70, a first airborne projectile 71 are respectively used. and a second airborne projectile 72, the last two of which are stationary mounted together with the main tank 21 on the vehicle, and the submersible projectile 70 is located on the vehicle operation with the possibility of its immersion to a depth through winch rope 69. In addition, in the vehicle mounted compressor 20, a vacuum and slurry pumps 19 and 18, respectively, driven by the power plant of the vehicle 75.

To communicate the mentioned pumps 18, 19 and compressor 20 with tanks 21, 70, 71, 72, the installation is equipped with pipe fittings made in the form of rigid 1 and flexible 2 pipelines.

The main tank 21 is made with two inputs, the first of which is connected to the vacuum pump 19 through the control unit 73, and the second input is configured to communicate with the liquid medium, and with one output for communication with the slurry pump 17. Additional containers, respectively, submersible the projectile 70, the first airborne projectile 71 and the second airborne projectile 72, are made with two inputs, the first of which is connected either to the vacuum pump 19 or to the compressor 20 according to the commands of the control unit 73, and the second entrance to the suction liquid medium during filling tions, and with one output - to empty the container from the liquid medium. The mentioned inputs and outputs of the main 21 and additional tanks are equipped with check valves 61, 62, 63, 64, 65, 66, 67 with the possibility of eliminating the reverse movement of the liquid medium.

The control unit 73 of the processes of filling and emptying of said containers is equipped with sensors of maximum and minimum levels 53, 54, 55, 56, 57, 58, 59, 60, respectively, of the maximum and minimum levels of sucked-in liquid medium, said sensors being located in said containers, i.e. e. each tank has two level sensors.

In addition, to control the filling and emptying of the main tank 21, the control unit 73 contains the first, second and third controlled valves made by electromagnetic, namely 23, 24, 27, as well as cranes 32, 33, 34, 35, 36, 37, controlled manually and duplicate solenoid valves, said valves and taps being intended for: communicating the main tank 21 with the vacuum pump 19, for communicating the main tank 21 and the vacuum pump 19 with the atmosphere, and for communicating the main tank 21 with the slurry pump 17 in the pumping mode inside the main container 21 of the liquid medium. Moreover, the said controlled valves 23, 24 and 27 are connected with level sensors 53 and 54 with the possibility of controlling the filling and emptying of the liquid medium depending on the state of the level of the liquid medium in the main tank 21.

To control the filling and emptying of additional containers, which are: a submersible shell 70 and airborne shells 71, 72, the control unit 73 contains a fourth, fifth, sixth, seventh, eighth and ninth controlled valves made by electromagnetic, namely electromagnetic valves 25 , 26, 28, 29, 30, 31, as well as cranes 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, manually controlled and redundant solenoid valves, said valves and cranes are intended: for the communication of additional tanks with a vacuum pump 19 and creating a high vacuum in them with the possibility of filling them with a liquid medium, as well as for communicating these containers with a compressor 20 with the possibility of displacing a liquid medium from them, while the aforementioned controlled valves are switched to the "closed" mode.

For efficient operation, the main tank 21 and the submersible projectile 70 are equipped with coarse filters 68 located at the second entrances and made mesh.

In order to expand the functionality, the mobile vacuum tubing unit is equipped with another additional tank 22 for clean water, used, in particular, to supply the population with drinking water, the filling and emptying of which is carried out similarly to other additional tanks.

Installation works as follows.

At the commands of the control unit 73, the drive 18 is turned on (Fig. 1, 2, 3, 4-10), kinematically connected to the vehicle engine, the vacuum pump 19 and the slurry pump 17 are activated. Next, the control unit 73 is turned on, in the corresponding operating mode, the first, second and third controlled valves, namely the electromagnetic valves 23, 24, 27. So, for example, through the flexible pipe 3, the electromagnetic valve 23, the valve 33 and the flexible pipe 2 in the main tank 21 creates a vacuum until a deep vacuum. Through the taps 47, 50 and the coarse filter 68, made in the form of a receiving grid, the tank 21 is filled, as it is filled to the maximum level, the level sensor 54 is turned on and the electromagnetic valve 23 is turned off and the electromagnetic valves 24 and 27 are turned on. At the same time, the vacuum the pump 19 communicates with the atmosphere, and the main tank 21 is depressurized. The slurry pump 17 starts pumping liquid from the tank 21 through the valve 38. After emptying the tank 21, the solenoid valves 24 and 27 are turned off by the command of the level sensor 28, and the solenoid valve 23 is turned on, the next stage of filling the main tank 21 begins using vacuum. This principle of filling and emptying the tank is the basis for the operation of the installation.

To rise from the depth of the liquid medium, an immersion projectile 70 is used, which descends to a depth, for example, into a drainage pit (or well, etc.). In the control unit 73, the fourth and fifth controlled valves are actuated, namely, the electromagnetic valves 25 and 26. In this case, the flexible pipes 4 and 10 communicated through the control unit 73, the first with the vacuum pump 19 and compressor 20, and the second with the external medium, are connected by means of a detachable connection, for example, a plug, to the submersible projectile 70. At the command of the control unit 73, the drive 18 is turned on and pumping of air from the submersible projectile 70 and its filling with the pumped liquid medium begins. As the submersible projectile 70 is filled to the maximum mark, the level sensor 55 is turned on, the solenoid valve 25 is turned off and the solenoid valve 26 is turned on, compressed air from the compressor 20 rushes into the immersion projectile 70 and displaces the liquid medium through the pipe 11 under high pressure. the sensor 56 generates a signal to turn off the solenoid valve 26 and the cycle repeats.

During the continuous collection and supply of the liquid medium, additional containers are activated, namely the on-board projectiles 71 and 72. For this, by the command of the control unit 73, the valve 50 is closed, the valve 40 is opened, the actuator 18 is turned on, and then the sixth, seventh, eighth and ninth operated valves, namely, electromagnetic valves 28, 29, 30, 31. Air starts to be pumped out of the airborne shells 71 and 72 (Fig. 3) and the formation of a deep vacuum, due to which they are filled with liquid medium through the crane 45. Airborne shells 71 and 72 work similarly about the submersible projectile 70, they are only installed stationary on the common platform of the vehicle 75, the liquid medium is supplied by means of a flexible pipe 5 and a crane 40. The airborne shells 71 and 72 operate independently of each other, so the continuity of supply is ensured by the selection of the cross-section and length of the pipelines.

The use of the present invention allows to significantly expand the technical capabilities of using a mobile vacuum tubing installation, in particular, for:

- pumping hydraulic mixtures from drainage reservoirs, lifting water from reservoirs with a steep coastline;

- continuous pumping of water during the elimination of pipeline breakthroughs;

- abstraction and pumping of water with a complex coastline;

- fire extinguishing;

- pumping and buildup of bottom sediments of RVS;

- pumping from railway tanks of viscous and solidifying oil products;

- collection and pumping of oil (oil sludge) and oil products;

- collection and pumping of high viscosity mixtures with a high content of solids from long distances, large depths and continuous supply over long distances.
