Description

The utility model relates to devices used in well cleaning, in particular for cleaning and restoring drinking water wells.

Currently, many devices are used to restore and clean wells, the use of which is based on loosening or erosion of solid soil or contaminants that have clogged the well and the subsequent removal of this soil, as well as contaminants. So, for example, there is a known method of cleaning wells using a device that is a steel pipe with a mechanical valve on one side. Valves can be of various designs, for example, ball or petal, other designs are possible (Balker: types of product for cleaning a well / [Electronic resource] - URL: https://stroy-podskazka.ru/vodosnabzhenie/skvazhina/zhelonka / (date address 02/26/2022).To clean the well with the help of such a device, it is dropped to the bottom of the well from a certain height.At the same time, clogging soil gets into the lower part of the device, the fallout of which is delayed by the valve.For several drops, the lower part of the pipe is filled with soil, it is pulled out, the soil is removed, then the cleaning is continued.The disadvantage of this device is the high complexity of cleaning.

It is also known to use a device for cleaning wells, which is often referred to as an airlift or airlift. In general, the device consists of two lines made in pipes, along one line a liquid (water) or gas (air) is injected into the well under pressure, with the help of which solid deposits are eroded at the bottom of the well, and the pulp is pumped out along the other line - the pipe. In this case, the injection line or pressure line ends with a hollow rod, through which solid bottom sediments are washed out (Airlift for a well / [Electronic resource] - URL: https://clean-well.rf/chistka-skvazhinyi-methodom-erlifta / (date 02/26/2022) The disadvantage of this device is the limitations on the removal of coarse-grained contaminant fractions.

The closest (prototype) in terms of essential features to the claimed utility model is a device that is a hollow cylindrical body with a tapered and outwardly directed base, at the very end of which a branch pipe protruding in both directions is inserted in the center. The upper side of the housing, along its boundary - the circumference, is attached to the pump housing with a lower water intake, which, when connected, is in the upper part of the device housing. Attachment is carried out using adhesive tape - scotch tape. The device is lowered to the bottom of the well, the lower end of the nozzle touches the bottom. When the pump is turned on, water is drawn through the pipe. Along with the flow of sucked-in water, contaminants are taken from the bottom - sand and pebbles, which, when leaving the upper end of the pipe, fall off to the side between the pipe and the body wall. Contaminants are removed when the device is removed. (Production of a nozzle for a pump for cleaning a well / [Electronic resource] - URL: http://usadba-kirov.ru/infrastruktura-usadbv/kak-ochistit-skvazhinu.html / (accessed 26.02.2022). The disadvantage of this device is restrictions on the removal of coarse-grained fractions of contaminants and low productivity.

The problem to be solved by the claimed utility model is to increase the productivity of the well cleaning process, as well as to expand the arsenal of technical means of well cleaning devices. In this case, the purpose of the claimed utility model is the implementation of a device for cleaning wells. The technical result is to increase the productivity of the well cleaning process.

The achievement of the specified technical result in the claimed utility model is achieved through the implementation of a device for cleaning wells for water, including a hollow cylindrical body, open on one side and having a bottom with a pipe mounted in it on the opposite side. At the same time, the device is provided with a fluid injection line attached to the body in the form of a tubular element with a guided tip attached to it, the open part of the body is made with the possibility of attachment to the pump, the opposite part of the body with the bottom is provided with tools for loosening well impurities connected to it.

The claimed utility model has the following essential features common with the closest analogue: a hollow cylindrical body, open on one side and having a bottom with a pipe mounted in it on the opposite side.

The claimed utility model is distinguished from the prototype by the following essential features:

- the device is equipped with a fluid injection line attached to the body in the form of a tubular element with a guided tip attached to it,

- the open part of the housing is made with the possibility of attachment to the pump,

- the opposite part of the body with the bottom is equipped with tools connected to it for loosening the contamination of the well.

These essential features are distinctive from the prototype, because each of them is not contained in the totality of the essential features of the prototype, i.e. are not present in the list of features implemented in the prototype, and are not their characteristic.

For an unambiguous and more complete understanding of the description of the device for cleaning wells for water (cleaning device), the following are explanations and clarifications of the concepts and terms used above, as well as disclosure of the features of the utility model, indicating the cause-and-effect relationships of their implementation.

The claimed device is a set of structural elements united by a single creative concept and made as a single technical solution. The device is intended for cleaning wells, primarily water wells, from silt, sand, stones and other contaminants with a solid particle size of up to 20 - 50 mm, depending on the pump power. Cleaning is carried out by carrying out the process of washing out contaminants with a fluid stream supplied under pressure from the injection line using a guided tip. A guided tip should be understood as a tip capable of taking the required direction towards contaminants in the well space. In practice, such directions are determined by places where pollution accumulates. A fluid medium is primarily to be understood as a medium based on water and its mixtures, as well as based on a gaseous mixture, in particular air. (Fluid media include gas and liquid - Scientific and Technical Encyclopedic Dictionary / [Electronic resource] - URL: https://dic.academic.ru/dic.nsf/ntes/4704/FLUID / (accessed 26.02.2022). To intensify the process of cleaning the well from contamination, the fluid medium may contain various additives, for example, acidic, alkaline, and also complexing agents.

Suspended contaminants are sucked in by a current (flow) of water through a narrowing hole in the bottom of the device body, namely through a pipe. The flow picks up impurities (sludge) - silt, sand, pebbles - from the area of contamination erosion in the well and directs them through the branch pipe to the area of the hollow body of the device. The flow is organized by the suction of water by a pump, the suction holes of which are located in the upper part of the device body. This part of the body of the device can also be called the connection area of the device to the pump. When the water flow leaves the nozzle, the flow rate and pressure in it fall. In this case, the particles of contaminants move to the periphery of the flow and then fall out between the walls of the branch pipe and the housing. After filling the space between the walls of the housing and the branch pipe, the housing with the pump is removed from the well and freed from contamination. Then the process is repeated until the required degree of cleaning of the well. It should be noted again that the proposed device works only in tandem with the pump. Submersible pumps with lower water intake of various designs can be used as a pump, for example, a vibration pump VN-5N Whirlwind, a vibration pump Stream, a vibration well pump Krepysh VER60-1-10, a submersible vibration pump STAVMASH, a borehole pump Dzhileks, a water cannon PROF 55 /90.

The basis of the design of the device is a hollow cylindrical body. The case material can be steel, aluminum alloy, polymeric materials. In the simplest case, the housing is made from a pipe with an inner diameter close to the diameter of the pump being used. The upper part of the housing is open and made with the possibility of placing a pump in it, for which it contains a device for connecting to the pump. The pump is inserted into the housing with suction holes inward. The connection device, as a rule, is made along the upper boundary of the body, which has a circular configuration. Such a device can be a clamp, a tight cuff, a tightening gasket, stops with a gasket, and others. Such devices allow you to quickly disconnect the pump and free the housing from contamination. In addition, the body itself may contain special windows for unloading contaminants. Pollution accumulates in the space between the walls of the chamber and the nozzle. The degree of filling of the body of the device is determined by its weight. The connection of the device to the pump itself is carried out, as a rule, in the central part of the pump, in its widest part or in the area of the flanges of the pump housing.

On the side of the housing opposite to the open side, the bottom of the housing is made. The bottom contains a hollow pipe mounted in it, which is directed at one end towards the pump, and at the other in the opposite direction from the pump. The nozzle can be either cylindrical or conical. In the case of a branch pipe in a conical shape, the top of the cone is turned towards the pump. The nozzle opening on the pump side acts as a diffuser for the flow passing through it. The connection of the branch pipe with the bottom of the hollow body of the device can be made both detachable and one-piece. The detachable connection can be made, for example, on a thread or due to a tight fit, on latches. The permanent connection can be made, for example, by welding. It is also possible to make the branch pipe with the possibility of displacement along the body axis. Such an implementation is possible, for example, in the case of mounting a nozzle due to a sliding or tight fit in the bottom of the device housing. A non-return valve can be attached to the branch pipe as an external, relative to it, device. In this case, the reverse means preventing water, suspensions, suspensions from flowing out of the hollow body. The latter may be present, for example, in quicksand.

On the lower part of the body, including the bottom, tools are used to loosen the contamination of the well. These can be teeth, protrusions, plates, cutters directed with their protrusions or tip towards the bottom, as well as the walls of the well. These tools are designed to loosen the bottom of the well or to clean its side walls when the device performs vertical reciprocating or oscillatory or rotational movements. Loosening tools can be made in both stationary and removable (replaceable) versions. In the first case, they are made integral with the body or welded to it, in the second case, they are attached using a threaded connection or a tight fit. Also, loosening tools can be made on special interchangeable devices attached to the bottom of the body. This attachment can be done with threaded connections, clamps or special fits. The efficiency of loosening dirt with loosening tools depends to a large extent on the weight of the device. An increase in mass contributes to the intensification of the process, but limits the possibility of servicing the device. Therefore, the mass of the device is selected empirically due to the selection of materials and the size of the body and in practice is 7.8 kg. The height of the cylindrical body of the installation can vary from 1 to 3 m, while the amount of sludge can reach 15-20 kg.

The fluid injection line has the purpose of supplying under pressure a directed flow of this medium to the contaminants in the well in order to transfer them to suspension. The discharge line consists of a tubular structural element and a tip flexibly (movably) connected to it, which has the function of changing the direction of the water jet in the space near the bottom. The tubular structural element may be a piece of metal or plastic tube or hose. At one end of the tubular element, an element for connecting to the water supply line can be made, on the other hand, a guided tip is attached. Fittings and clamps can be used as an element of connection. The guiding handpiece is attached through a flexible bracket or elbows (swivels). The location of the fluid injection line or tubular element relative to the body of the device can be different: it can be located on the outer or inner side along the walls of the body, it can be located inside the body. Attachment of a tubular structural element to the walls of the housing can be carried out, for example, by welding, clips, clamps, as well as other known methods and devices.

The implementation of the purpose of the fluid injection line is carried out by connecting to it a supply line of a fluid under pressure or a pressure line from a pump. Another option for implementing its purpose is to use a bypass line when diverting part of the water from the pressure line at the outlet of the pump. The greatest efficiency of the process of washing out contaminants and, accordingly, cleaning is achieved with a complete discharge of the flow at the outlet of the pump for washing out contaminants, followed by suction of clarified water after the dumping of the sludge.

On the body of the device can be made various devices to ensure maintenance operations. Thus, lugs can be made in the upper part, eye bolts or eye nuts are mounted to remove the device from the well or control the vertical reciprocating movements of the device. Devices can also be made on the side surface, allowing the device to perform oscillatory and rotational movements. In case of disconnection and breakage of the lifting cables, a safety cable is used, which, with its free end, is wound through the lugs of the pump into the lugs of the device. Thereby securely binding them for a guaranteed rise to the surface.

The claimed utility model is a technical solution, because represents a solution to the problem of achieving the claimed technical result by creating a device consisting of structural elements - a hollow cylindrical body, a bottom, a branch pipe, loosening tools, an attachment device, as well as a fluid injection line technologically and structurally interconnected. At the same time, the entire set of essential features of this utility model - a system of structural elements - is united by a single creative concept, namely, the implementation of a device for cleaning wells for water by washing out contaminants, using the suction force of the pump to capture sludge by organizing a high-speed fluid flow through a narrow pipe with a sharp drop speed at the outlet of the nozzle.

The claimed utility model is carried out as follows.

According to the claimed technical solution, the device 1 for cleaning wells for water 2 is paired with a pump 3. As the main element, it contains a hollow cylindrical body 4, which is open on one side, i.e. has no basis. On the opposite side, the body is closed with a bottom 5, in which a branch pipe 6 is mounted. The branch pipe can be made both in the form of a cylinder and in the form of a cone facing the top towards the pump. The connection of the branch pipe with the bottom of the hollow body of the device can be made both detachable, for example, threaded, and one-piece, for example, welded. The upper part of the body contains a connection device 7 to the pump. The connection device, as a rule, is made along the upper boundary of the body, which has a circular configuration. Such a device can be a clamp, a tight cuff, a tightening gasket, stops with a gasket. In the lower part of the body, including the bottom, there are tools for loosening 8 impurities 9 of the well. These are teeth, protrusions, plates, cutters. These tools are designed to loosen the bottom of the well or to clean its side walls when the device performs vertical reciprocating or oscillatory or rotational movements. The device also includes a fluid injection line 10 for supplying pressurized water to wash away contaminants and a guided tip 11 for directing the flow of water.

On the body of the device can be made various devices to ensure maintenance operations. In the upper part, lugs, eye bolts, eye nuts are made to remove the device from the well or control vertical reciprocating movements. Devices can also be made on the side surface of the device body, allowing to perform oscillatory and rotational movements with the device. The design may also contain a safety cable that prevents the device from falling in case of emergency. As a rule, the cable is attached to the bottom of the case. It is connected to the lugs of the pump, as well as the device and is calibrated to the center with clamps with subsequent output to the surface to the lifting device.

A water pump is inserted into the body of the device, which has a cylindrical or conical nozzle and loosening tools, with suction holes towards the nozzle. After that, the top of the housing is attached to the pump using an attachment device, for example, using a clamp. A separate pressurized water line or bypass line is connected to the fluid injection line from the outlet on the pressure line of the pump. In the latter case, the bypass line is organized through a three-way valve 12 installed at the outlet of the pump.

The assembled structure is lowered on one or more cables to the bottom of the well, which contains water, and the pump is turned on. The cables are control elements, using them, make vertical reciprocating movements of the device with the pump, while hitting the bottom of the device (having loosening protrusions) with the pump on the bottom. It is also possible to use oscillatory and rotational movements. Sludge - sand, silt, pebbles - enters the body cavity with the sucked-in water. The weight of the device with the pump determines the degree of filling of the housing cavity. Then the structure is removed from the well, the device is disconnected and cleaned. The process is repeated until the required degree of well cleaning.

Along the edge of the open part of the cylindrical body, 4 lugs are also made at an equal distance from each other. A cylindrical branch pipe is mounted in the bottom of the housing from the inside by means of a threaded connection. The branch pipe is completely located inside the body. On the outer side of the bottom and along its edges, teeth were made, the tip of which was directed to the outside. Connected to the fluid injection line is a separate pressurized air supply line, which is powered by a separate surface mounted compressor. An adjustable guide tip is directed in the intended direction of the accumulation of contaminants. From the open side, the lower half of the “Kid” pump, with a power of 260 W, is inserted into the body of the device and secured with a lever clamp. A cable is attached to each eye. The pump also contains a power supply line and a drainage hose. The assembled structure is lowered to the bottom of a well 20 m deep, with a layer of silt, sand and pebbles 1.5 m thick.

After lowering the structure, the pump is turned on in the device case, as well as the pump on the surface, and they begin to carry out vertical reciprocating movements using 2 cables, and then rotational movements using all 4 cables. After 10-15 minutes, the pump and air compressor are turned off, the structure is removed, the device is disconnected and silt, sand and pebbles are unloaded. After that, the device is again attached to the pump and the process is repeated. After 3 iterations, the device with the pump began to touch the bottom of the well, and cleaning was completed. The unloading amounted to about 10 kg of cuttings when cleaning 1 meter of a well with a diameter of 133 mm. In the case of shutting off the water supply line from the second pump on the surface, 4 iterations lasting 15 minutes are required for cleaning.

Example 3

As a connection device in the inner part of the device housing to the pump, near the edge of the housing, stops were made in the form of protrusions inward. These protrusions were overlaid with an O-ring made of soft rubber. This design is designed to accommodate the pump in the cavity of the chamber by applying its flanges to the gasket. The body of the device was made of st40. When the pump is turned on and water is sucked out of the housing cavity, the pump is pressed against the gasket. Along the edge of the open part of the cylindrical body, 4 lugs are also made at an equal distance from each other. In the bottom of the housing from the inside, a conical branch pipe was mounted by means of a welded joint. The branch pipe was completely located inside the body. A bypass line from the output of the pump pressure line is connected to the fluid injection line through a three-way valve. The guided tip is directed in the intended direction of the accumulation of contaminants. On the outer side of the bottom, along its edge, teeth were made, the tip of which was directed to the outside. On the outer side of the body, in its lower part, protruding and vertically oriented plates were made to clean the side surface of the well. From the open side, the lower half of the Aquarius pump, with a power of 650 W, is inserted into the body of the device with flanges on the gasket. A cable is attached to each eye. The pump also contains a power supply line and a drainage hose. The assembled structure is lowered to the bottom of a well 70 m deep, with a layer of silt, sand and pebbles 0.6 m thick. The diameter of the well is 200 mm. On the sides of the well, in its lower part, there is limescale. After lowering the structure, turn on the pump and begin to carry out vertical reciprocating movements using 2 cables, and then rotational movements using all 4 cables. When performing rotational movements, the structure is raised to the height of the lateral deposits. After 15 minutes, the pump is turned off, the structure is removed, the device is disconnected and silt, sand and pebbles are unloaded. After that, the device is again attached to the pump and the process is repeated. After 4 iterations, the device with the pump began to touch the bottom of the well, and cleaning was completed. If the bypass line is blocked, cleaning requires 6 iterations lasting 20 min.

Example 4

The device for cleaning water wells was made of St20 and has a threaded connection (ring with external thread) as a connection device, made along the edge of the open part of the cylindrical body of the device. In accordance with this, for connection with the device, a mating threaded ring with a thermoplastic sleeve is installed along the edge of the pump using hot glue. A cylindrical branch pipe is mounted in the bottom of the housing from the inside by means of a threaded connection. The branch pipe is completely located inside the body. On the outer side of the bottom and along its edges, protrusions were made to loosen the bottom of the well, the tip of which was directed to the outside. Connected to the fluid injection line is a pressure water line coming from the surface from the pump. The guided tip is directed in the intended direction of the accumulation of contaminants. From the open side, the lower half of the Patriot pump, with a power of 300 W, is inserted into the body of the device and fixed with a threaded connection. A cable is attached to each eye of the pump and fitted with 2 clamps, centering to the latter. The pump also contains a power supply line and a drainage hose. The assembled structure is lowered to the bottom of the well 7 m deep, with a layer of silt, sand and peat deposits 1.7 m thick. The diameter of the well is 133 mm. After the structure is lowered, the pump is turned on in the device housing and vertical reciprocating movements are started using 2 cables, and then rotational movements using all 4 cables. At the same time, the cock for washing out pollution is closed. After 2 minutes, the pump is turned off, the structure is removed, the device is disconnected and silt, sand and peat are unloaded. After that, the device is again attached to the pump and the process is repeated. After 2 iterations, the device touched the soft bottom of the well - turn on the three-way valve and repeat the process. After 2 iterations, the device with the pump began to touch the solid bottom of the well, the device was removed, disconnected and unloaded silt, sand, peat. Cleaning completed. The unloading amounted to about 17 kg of sludge when cleaning a 1.7 meter peat hole with a diameter of 133 mm. Purification requires 4 iterations with a total duration of 24 min.
