A mobile technological complex is known for eliminating accidents on a ground collapsible oil product pipeline with a “bell” connection (patent for FROM RU No. 2726986, IPC B60P 3/14, B60P 1/54, F16L 1/024, publ. 17.07.2020 Bull. No. 20), which contains a load-lifting crane-manipulator mounted on an elongated base chassis of the vehicle, fixed to the driver's cab and, for placing pipeline modules, a cargo platform with a roof for their shelter, characterized in that the complex additionally contains a removable operator compartment installed at the front end of the cargo platform, on on the roof of which there is a telescopic radio antenna, behind the removable operator compartment on the cargo platform, at one of the sides, two narrow-gauge metal tracks are attached to the floor along its entire length for placement and movement of rigid containers, continuing on the rear opening with a slope to the horizontal surface at an angle of not more than 30 ° board, along the other longitudinal vertical side of the cargo platform The storage-transportation unit of pipeline modules is made on the frame, consisting of metal vertical racks rigidly attached to the floor in two rows, along the height of each of which coaxial holes are made remote from each other at a distance of at least 1.5 diameters of the pipeline module, in which horizontal jumpers with rotating rollers placed on them at a certain distance with lodgements, the depth of which is not less than 1/3 of the diameter of the pipeline module, and at the free end of the vertical racks there are fixing elements that exclude vertical and horizontal movements of the pipeline modules during their transportation to the accident site, cargo roof The platform is made in the form of a flexible corrugated awning rigidly connected to the front end of the loading platform, moving up to the travel limiter along U-shaped guides, which are fixed on the outer longitudinal ends of the loading platform, while narrow-gauge metal tracks on the rear b ortu are made telescopic in the direction of contact with the ground.

The known device has a number of disadvantages, including the complexity of the design with the use of special vehicles, as well as the dimensions of the installation, which do not allow repair work at technological facilities with limited access roads.

A self-contained mobile vacuum unit for collecting spilled liquids is known (patent for PM RU No. 62937, IPC E02B 15/00, E01H 1/00, publ. collection of liquid, a vacuum pump, an engine for driving a vacuum pump and shut-off and distribution valves, characterized in that the container for collecting liquid is installed on the rear of the trailer area and has an oval shape in cross section, the larger diameter of which is at least 0.9 of the width of the trailer , and the length of the container is at least half the length of the trailer, while the angle of inclination of the axis of the container relative to the bottom of the trailer is not more than 15 °, a vacuum pump, an engine for driving the vacuum pump and shut-off and distribution valves are installed on the front remaining part of the trailer.

The disadvantage of this technical solution is the operation on the principle of pumping out the process fluid, since it requires the use of additional equipment to create a vacuum, which greatly complicates its design, as well as the insufficient versatility of the device, since pumping the process fluid from the surface of the pipeline will lead to a partial spill near the place of repair work.

The closest is a mobile technological complex for cleaning tanks (patent for PM RU No. 86506, IPC B08B 9/08, B08B 9/093 publ. 10.09.2009 Bull. No. 25), containing equipment installed on a vehicle, including a cleaning fluid supply system , connected by a pipeline with a shut-off valve passing through the technological hatch of the cleaned tank to the gripping device of the eroded sediment pumping system, which contains a means for creating a vacuum connected to the collection tank, in the lower part of which there are branch pipes with shut-off valves for filling, draining jelly-like waste and draining contaminated liquid and which is equipped with a level gauge, the control output of which is connected to the starter of the means of creating a vacuum, characterized in that it additionally contains a gravity separation unit connected through a coarse filter to the branch pipe for draining contaminated liquid from the collection tank of the fuzzy sediment pumping system of contaminated liquid into water, oil product and jelly-like waste, a water purification plant, an after-treatment plant for oil products and a solid and jelly-like waste disposal unit, consisting of a waste incineration unit connected to a waste storage tank, the inlet of which is connected by individual pipelines to a branch pipe for draining jelly-like waste from the tank - of the collection system for pumping out eroded sediments, with a branch pipe for draining jelly-like waste from the installation for the gravitational separation of contaminated liquid and with the first outlet of the installation for post-treatment of oil products, the inlet of which is connected to the branch pipe for draining oil products from the installation for the gravitational separation of contaminated liquid, the branch pipe for draining the separated water from which is connected to the first inlet of the installation aftertreatment of water, made in the form of two flotators connected in series along the flow and forming a closed circuit, a treated water storage tank and a liquid pump, the pressure line of which through the corresponding shut-off valves ana is connected either to the inlet of the first flotator, or to the gravity separation unit, or to the line for draining water into the sewer, the bottom branch pipe of each flotator is connected through the appropriate shut-off valve to the pipeline connecting the drain pipe of the jelly-like waste of the contaminated liquid gravity separation plant with the inlet of the storage tank of the solids disposal plant and jelly-like waste, while the gravitational separation unit is additionally connected to the inlet of the storage tank of the water post-treatment unit, the outlet of which is connected to the inlet of the washing liquid supply system and to the suction pipe of the liquid pump of the water post-treatment unit.

The disadvantage of this device is that it works on the principle of pumping out the process fluid, since it requires the use of additional equipment to create a vacuum, which greatly complicates its design, as well as the lack of versatility of the device, since pumping the process fluid from the surface of the pipeline will lead to a partial spill near the place of repair work.

The technical task of the proposed technical solution is to create a simple and versatile mobile process fluid receiver with the ability to adjust the receiving tray, prevent spillage of the process fluid at the points of maintenance or repair of the surface pipeline, and return the process fluid to the process.

The technical problem is solved by a mobile process fluid receiver, which contains a mobile base with a receiving tray connected by process fluid drain pipes with a collection tank equipped with a level gauge, in the lower part of which there is at least one pipe with a shut-off valve for draining the process fluid.

The mobile receiver of the process liquid contains a mobile base 1 (Fig. 1-7) with a receiving tray 2 connected by drain pipes of the process liquid 3 with a reservoir-collector 5 equipped with a level gauge 4 (Fig. 6) (Fig. 1-3 and 6), in at the bottom of which there is at least one branch pipe 6 (Fig. 3 and 6) with a shut-off valve 7 for draining the process fluid. The mobile base can be made of any known material, depending on the required volume of the received liquid, for example, metal, polymeric materials. The movement of the mobile base 1 (Fig. 1–7) can be carried out using wheels (shown conditionally), as well as any other known method, for example, on a sled, sledge, etc. The mobile base 1 is equipped with at least one handle 8 (Fig. 1, 2, 4 and 7) for manual movement and is made in the form of two boxes 9 (1–3, 5 and 7), rigidly connected to each other and equipped with the same synchronized (not shown) with hydraulic jacks 10 (Figs. 5 and 7) with a hand pump (conditionally shown) with a control handle 11 (Figs. 1, 3 and 4) protruding beyond one of the boxes through window 12. Box connections 9 (1–3, 5 and 7) can be made by any known method, such as welding, gluing, etc. The rod 13 (Fig. 5 and 7) of each hydraulic jack 10 is equipped with a cross member 14, with which a pair of parallel pushers 16 and 16' is pivotally connected 15, interacting with the receiving tray 2 to move it up and down. Pushers 16 - 16 and 16 '- 16 ' of different boxes 9 are equipped in pairs on top with rotary longitudinal jumpers 17 so that parallel wings are formed - a drawing board. In one of the housings 9 (Fig. 2 and 5) an additional hydraulic jack 18 is installed with its pump (shown conditionally), control handle 19 and rod 20 (Fig. 2) located between a pair of rods 13 perpendicular to their movement up and down and equipped with a jumper 21 with swivel sleeves 22 slidably enclosing respective pairs of pushers 16 and 16 for their transverse movement. The cross member 14 (FIGS. 5 and 7) and the pushers 16 and 16' may be made of any known material suitable for the applied loads, such as metal, composite materials, and the like. The authors do not pretend to the design and functionality of the level gauge 4 (Fig. 4), for example, it can transmit a signal about the filling of the reservoir 5 to the control point, it can emit an audible signal, it can communicate with an external transparent tube for visual control, etc. P.

Structural elements and technological connections that do not affect the performance of the mobile receiver of the process fluid in the drawings (Fig. 1–7) are not shown or are shown conditionally.

The device works as follows.

The mobile process fluid receiver (Fig. 1-7) is transported to the repair site and installed under the pipeline (not shown) using the handle for manual movement 8 (Fig. 1, 2, 4, 5, 6, 7) in such a way that the mobile base 1 and the receiving tray 2 were below the level of the pipeline. In the window 12 there is a control handle 11 (Fig. 1, 3, 4, 5, 7), pressing which activates the hydraulic jacks 10 located in the boxes 9. The rods 13 and 13' raise the cross member 14 and 14', on which the 15, a pair of pushers 16 and 16' are connected, and the receiving tray 2 rises to the desired height under the repair site (FIGS. 5, 7). Pressing the control handle 19 actuates the hydraulic jack 18, which actuates the rod 20 and through the jumper 21 and the rotary bushings 22 exerts perpendicular pressure on the pushers 16, which begin to shift depending on the pressure in the hydraulic jack 18 (Fig. 5). In this case, the receiving tray 2 remains level relative to the horizontal due to the rotary longitudinal bridges 17 (Fig. 5). The received process fluid (not shown) enters the receiving tray 2 and drains through the drain pipes of the process fluid 3 into the collection tank 5. The level gauge 4 will inform about the filling of the collection tank 5 by giving an audible signal when the received liquid reaches a critical level (Fig. 6). The receiving tray 2 is lowered down by depressurizing the hydraulic jack 10, aligned in the center with the help of the hydraulic jack 18 and transported to the place where the process fluid is returned to the process or disposed of (not shown). The process fluid is drained by opening the shut-off valve 7 through the pipe 6 (Fig. 6).

The proposed technical solution is simple and versatile due to its mobility and simplicity of the elements used. The ability to adjust the receiving tray allows you to work at various technological facilities, prevents the spill of process fluid in the places of maintenance or repair of the ground pipeline. The process fluid collected in the collection tank is returned to the process or drained into the collector through the nozzle when the shut-off valve is opened.
