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 26.02.2022). 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. After several drops, the lower part of the pipe is filled with soil, I pull it out) , remove the soil], then continue cleaning. 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, but in 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 appeals on February 26, 2022). The disadvantage of this device are the restrictions on the removal of coarse-grained fractions of contaminants.

The closest (prototype) in terms of essential features to the claimed utility model is a device that is a hollow cylindrical body with a base tapering to a cone, 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 connected to the pump housing with a lower water intake, which, when connected, turns out to be 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 pipe 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. (Valera Fedorov. How to clean a well. 11/25/2011 / [Electronic resource] - URL: http://usadba-kirov.ru/infrastruktura-usadby/kak-ochistit-skvazhinu.html / (accessed 10/26/2021). of this device are 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 expand the arsenal of technical means of devices for cleaning wells. In this case, the purpose of the claimed utility model is the implementation of a device for cleaning wells.

The achievement of the specified technical result in the claimed utility model is achieved by implementing an attachment to the pump for cleaning wells for water, including a hollow cylindrical body, open on one side and having a bottom with a pipe mounted into it on the opposite side. In this case, the branch pipe is located at least half of its length inside this hollow body. At the same time, the open part of the body of the attachment has a device for connecting to the pump, and the opposite part of the body with the bottom has tools for loosening well impurities.

The claimed utility model has the following essential features in common with the closest analogue: a hollow cylindrical body, open on one side and having a bottom with a pipe mounted into it on the opposite side, the pipe at least half of its length is located inside this hollow body.

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

the open part of the attachment housing has a device for connecting to the pump;

the opposite part of the body with the bottom has tools for loosening well impurities.

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 attachment to the pump for cleaning wells for water, 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 - attachment to the pump is a set of structural elements united by a single creative concept and made as a single technical solution designed to clean wells, primarily water wells, from silt, sand, stones and other contaminants with a solid particle size of up to 20 50 mm depending on pump power. Cleaning is carried out by organizing a stream of water through a tapering hole in the bottom, namely through the hole in the hollow pipe, picking up contaminants - sludge (silt, sand, pebbles) from the area of the bottom in the well and directing them through the pipe to the area of the hollow body of the attachment. 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 console body. This part of the body of the attachment may also be referred to as the attachment area of the attachment. 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 nozzle and the body of the attachment. After filling the space between the walls of the housing and the branch pipe, the attachment 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 inventive prefix works only in tandem with the pump. Submersible pumps with lower water intake of various designs can be used as a pump, for example, the VN-5N vibration pump Whirlwind, the brook vibration pump, the Krepysh VHR60-1-10 vibration well pump, the STAVMASH submersible vibration pump, the Dzhileks Vodomet PROF 55/well pump 90.

The design of the attachment is based on 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 to accommodate the pump and contains a device for connecting to the pump. The pump is inserted into the attachment with the 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. 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.

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. In some cases, for example, for loose soils, sand, it is advisable to use a combined execution of the branch pipe, namely, the placement of its parts inside and outside the body, i.e. on both sides of the bottom. In this case, the outer part of the pipe can simultaneously act as an additional baking powder. In particular, such an embodiment can be easily implemented with a sliding fit of the nozzle in the bottom.

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 mass 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 by selecting materials and body size, depending on the diameter of the well and the structural arrangement of the filtration column, and in practice is 7-15 kg. The height of the cylindrical body of the installation can vary from 1 to 3 m, while the amount of sludge can reach 20-25 kg.

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 an accident, a safety cable is attached to the bottom from the inside of the housing, which, when leaving the housing, is passed under the connection device and then rises to the surface of the well.
