Description

[Detailed Description of the Invention] This invention consists of 1. Water wells, water wells that clean water wells, and baptism devices for water collection holes, in particular water wells that use the pressure of the liquid jetted onto the wall of the water well to rotate the bit at the same time to exert a digging action. Regarding baptismal devices for wells and water collection holes.

Conventionally, when working on water wells and water collection holes, a boring machine is rotated to stir and remove the buried sand that has flowed in from the screen pipe, the bit at the tip of the boring machine is stirred and removed, the bit is pulled out, and a pipe with a nozzle attached to the tip is inserted. The clogging of the screen pipe installed on the hole wall was removed using high-pressure water.

In such conventional construction methods, it is necessary to turn a long pipe with a bit-like shape, and the connecting screw is damaged due to the strong rotational twisting action. In addition, it was necessary to install a boring machine in the center of the hole in order to turn the pipe, making it impossible to work in narrow spaces.

This invention does not require the rotation of pipes, and has a mechanism that directly rotates the bit using the hydraulic pressure of the pump in the above-ground compressor's air pressure tank as power, which agitates and removes buried sand and gravel to improve excavation. The purpose is to provide a cleaning device for water wells and water collection holes that injects fluid into the screen pipe of the aquifer to improve the filtration effect of the gravel layer. A bit is connected to the rotating shaft of the fluid pressure motor, and a fluid discharge path of the fluid pressure motor is connected to a fluid discharge path in the direction of the bit and a fluid injection path in the direction of the wall of the water well and the water collection hole.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, reference numeral 1 denotes an insertion pipe, and a body case 3 having a built-in fluid pressure motor 2 is airtightly connected to the tip of the body pipe 1. The fluid pressure motor 2 is a motor that performs work by generating a rotational motion of an output +fl+ using fluid, and its rotor 4 has second and third rotors.
As shown in the figure, grooves 5 are formed radially, and sliding blades 6 are installed inside each groove 5, respectively.

As shown in FIGS. 4 and 5, the stator 7 that transmits rotational motion to the rotor 4 is eccentrically connected to the rotor 4 with one point at its upper end as a contact point.
A crescent-shaped space 8 is formed near the lower end. A fluid inflow path 9 is formed near one side of the stator 7, and is connected to the inflow path 9, extends in the rotational direction of the rotor 4, and is opened on the inner circumferential surface of the stator 7. A narrow inflow side cut window 10 is formed.

On the other hand, a similar outflow side cut window 11 is formed on the other side of the stator, and a fluid discharge passage 12 is formed in communication with this cut window 11. In addition, 13 shown in FIG. 1 is the rotor 4.
The rotating shaft has a tip protruding from the tip of the body case 3, and 14 and 15 are bearings that support the front and rear of the rotor 4, and each bearing cap is used as an airtight backing box to prevent fluid from entering. It is prevented.

A three-blade bit 16 is connected to the tip of the rotating shaft 13.

Furthermore, the inflow chamber 9 is provided on the inner peripheral surface of the body case 3.
At the same time, a sealed chamber 20a is formed at the tip of the body teeth 3, which communicates with the fluid discharge path 12. +? ;+ A/7++ llI'J

An injection hole 19 is formed in the f-7hII-npipe b direction, and the fluid from the fluid discharge path 12 flows through the injection hole 1.
8.19, the fluid is ejected from the injection path 20. In the embodiment, the fluid pressure is applied directly to the insertion pipe 1 to rotate the fluid pressure motor 2, but the fluid pressure motor 2
Fluid pressure may be applied by means of a hose directly connected to the inlet passage 9.

Next, the operation will be explained.

By pumping fluid into the insertion vibe 1 by a ground-based compressor or pump (not shown),
The pressurized fluid flows into the space 8 through the inflow groove 17, inflow path 9, and cut window 10, and collides with the sliding blade 6, causing the rotor 4 to rotate. The fluid passes through the space 8 in a clockwise direction and flows out into the outflow side cutout 11 and the fluid discharge path 12. As this fluid flow accelerates, the sliding blades 6 of the rotor 4 move out of the space 8-\JII] and are pushed against the inner wall of the stator 7, reducing fluid leakage. As the effect of the inflow pressure improves, the discharge pressure increases, and the bit 16 at the tip of the rotary shaft 13 is rotated with a large torque to dig.4 At the same time, the fluid from the fluid discharge path 12 passes through the fluid injection path 20 and is injected. Fluid is ejected from the hole 18 toward the bit 16, and from the injection hole 19, the screen pipe b
The fluid is ejected towards the screen pipe b to remove the clogging.

As described above, the present invention includes a fluid pressure motor near the tip of a pipe, a bit connected to the rotating shaft of the fluid pressure motor, and a fluid discharge path of the fluid pressure motor in the bit direction, a water well, Fluid sprays in the direction of the wall of the water collection hole.Since the fluid is connected to the channel, the bit can be rotated simply by sending it to a long insertion pipe with a bit by a compressor or pump, making it suitable for boring machines. Since no rotation is required, cleaning work of the water collection hole and screen pipe becomes very simple, and cleaning can be done economically.

In addition, since this invention eliminates the need to turn a long pipe with a bit, there is no damage to the connection screw due to the action of the powerful rotational twist 41, and the bit is rotated by a fluid pressure motor, so it can be used for extremely long pipes. The baptism construction method for water wells and water collection holes G is almost the same as for short lengths, and the effect of the simplicity of the construction method in terms of maintaining the screen pipe is great.

Furthermore, in conventional cleaning work, in order to turn the pipe with a boring machine, it was necessary to install the boring machine in the center of a water well, etc., and cleaning work could not be done in a narrower space than with a boring machine, but with this invention, the inserted pipe A fluid pressure motor is installed near the tip of the fluid pressure motor, a bit is connected to the rotating shaft of this fluid pressure motor, and fluid is sent to this fluid pressure motor by a compressor or pump installed at an appropriate location on the ground. :There is no need to place the compressor or pump at the center of a water well or the like. Therefore, it becomes possible to baptize water wells in narrow spaces, which was previously considered impossible. Furthermore, it is possible to use a high-pressure hose instead of a pipe.The installation location of the compressor or pump, which serves as a false power source, is not limited to the central part of a water well, so it is possible to use a powerful and large dynamic compressor or pump. This makes it possible to increase the pressure of the rotor of the fluid pressure motor and increase the stirring power of the bit and the digging power of sand and gravel.In addition, it is possible to increase the pressure of the rotor of the fluid pressure motor to increase the stirring power of the bit and the digging power of sand and gravel. By communicating the fluid injection path, the pressure to be injected into the screen pipe of a water well, etc. is increased, which removes blockages in the screen pipe, and also has the effect of cleaning gravel on the outside of the screen, which improves the filtration effect of the screen pipe. The efficiency can be made extremely effective.

This invention also allows the boring machine to be
Depending on your needs, equipment, construction, etc. may be very cheap (ill).
Not only is it more efficient, but it is also safer as it eliminates accidents caused by boring machines.
