TECHNICAL FIELD

[0001] The utility model relates to air compressor washing well technical field, especially a variable pipe diameter washing well gun head. BACKGROUND

[0002] In the drilling process, a large amount of rock debris, mud, silt and other precipitates will accumulate in the hole. The accumulation of precipitates will compress the pore of the aquifer and block the aquifer, reducing its permeability and affecting water circulation, resulting in a decrease in water yield or deterioration of water quality. By washing well, these precipitates can be pumped out, restoring the porosity of the aquifer and increasing the water yield of the well. After a long period of use, the well outlet is buried by precipitates, resulting in a decrease in water yield or dry well. Washing well can help restore the normal function of the well. The most commonly used method of washing well is air compressor washing well. The working principle of air compressor washing well is to use high-pressure gas generated by an air compressor to deliver to the lower end of the drain pipe. The pressure below the gas outlet of the air pipe is greater than that above the gas outlet, and the water is pressed out of the drain pipe. The water at the bottom of the well enters the drain pipe again, completing the effect of circulating drainage in the well.

[0003] The existing air compressor washing well equipment can discharge the sediment at the bottom of the well. The sediment on the well wall is usually cleaned by rotating the piston or steel wire brush well cleaning device. However, a single well cleaning device can only clean the well wall of a corresponding diameter well, and cannot clean the well wall of multiple diameter wells. UTILITY MODEL CONTENT

[0030] Its characterized in that: still include support ring 401, support arm 402 and steel wire brush fixed plate 403, support ring 401 is fixed on blowdown pipe 1 lateral wall, and support ring 401 is evenly hinged with a plurality of support arm 402 on the circumference, and the end of each support arm 402 is fixedly connected with steel wire brush fixed plate 403.

[0031] Furthermore, this utility model takes five sets of wire brush fixing plates 403 as an example. A support ring 401 is fixed at the connection between the suction nozzle 2 and the drain pipe 1. Five hinge ears are evenly arranged on the outer circumference of the support ring 401. Each hinge ear is hinged with a support arm 402. The support arm 402 is inclined and fixed to the wire brush fixing plate 403 at an angle of 25°. When the support arm 402 rotates downwards, it drives the wire brush fixing plate 403 to rotate downwards, moving it away from the drain pipe 1 and increasing the well wall washing diameter. When the support arm 402 rotates upwards, it drives the wire brush fixing plate 403 to rotate upwards, moving it closer to the drain pipe 1 and decreasing the well wall washing diameter. As the support arm 402 rotates around the sewage pipe 1, the washing diameter of the wire brush can be adjusted by increasing or decreasing the angle between the support arm 402 and the axis of the sewage pipe 1, thus enabling the washing of the well walls of water wells with different diameters.

[0032] When in use, the wire brush is wound into a ring shape. Figure 6 As shown, five wire brush fixing plates 403 are fixed together on the outside. A wire is passed through the fixing holes 410 to secure the wire brush to the fixing plates 403. The bosses 411 limit the wire brush, preventing it from detaching from the fixing plates 403. The wire brushes are fixed in a ring around the drain pipe 1. After the variable diameter well-washing gun head is placed perpendicularly into the well wall, the well wall is in contact with the wire brushes circumferentially, increasing the contact area and improving washing efficiency. Alternatively, five wire brushes can be fixed to five wire brush fixing plates 403 separately, and secured with wires passed through the fixing holes 410. During washing, the drain pipe 1 is rotated at a uniform speed, and the wire brushes brush off the dirt adhering to the inner side of the well wall.

When the sliding sleeve 406 slides downward, the sliding sleeve 406 pushes the support arm 402 to rotate downward through the push rod 407, thereby increasing the brushing distance of the steel wire brush fixing plate 403; when the sliding sleeve 406 slides upward, the sliding sleeve 406 pushes the support arm 402 to rotate upward through the push rod 407, thereby reducing the brushing distance of the steel wire brush fixing plate 403, and realizing equal distance adjustment of the brushing distance of multiple steel wire brush fixing plates 403.

[0035] Specific implementation method three: see Figures 1-3 As shown in the figure, the threaded pipe 405 located at the upper end of the sliding sleeve 406 is threadedly connected with the upper fixed ring 408, and the threaded pipe 405 located at the lower end of the sliding sleeve 406 is threadedly connected with the lower fixed ring 409.
