Description

TECHNICAL FIELD

[0001] The present application relates to a mine tunnel protection device, and more particularly to a fluid oscillation type flower pipe dredging device. BACKGROUND

[0002] In the process of mining in deep mines, high pressure water is a serious threat, and when construction reaches a water-rich section, water inrush accidents are likely to occur, which seriously restricts the safety production of mines.

[0003] Therefore, mines generally use directional drilling to drain and depressurize the water body of high-pressure water-rich structures (or strata) (or lower the water level of the water body below the roadway or ore body), and a filter flower pipe is lowered into the borehole to guide the pressure water out of the borehole, thereby reducing the risk of water inrush in mining engineering to ensure safety production.

[0004] However, the borehole is often affected by factors such as local stress changes, gravity, alteration, and rock powder accumulation, which can cause the water inlet hole of the flower pipe to be blocked, making it difficult for water to enter the flower pipe and be discharged, losing its original drainage function. SUMMARY

[0005] The purpose of the present application is to provide a fluid oscillation type flower pipe dredging device to dredge the water inlet hole of the flower pipe.

[0006] To achieve the above purpose, the technical solution adopted by the present application is to provide a fluid oscillation type flower pipe dredging device for dredging a blocked water inlet hole on a flower pipe inserted into a horizontal drainage and depressurization hole, comprising:

[0007] A first sealing portion is provided in the flower pipe near one end, and the first sealing portion is sealingly arranged with the flower pipe;

[0008] A second sealing portion is provided in the flower pipe near the other end relative to the one end of the first sealing portion, and the second sealing portion is sealingly arranged with the flower pipe, and the inner cavity of the flower pipe between the first sealing portion and the second sealing portion is provided as a dredging cavity;

[0009] An injection pipe is partially inserted into the dredging cavity, and the injection pipe is used to inject fluid into the dredging cavity;

[0010] An oscillation portion is provided on the second sealing portion, and when the pressure of the fluid in the dredging cavity reaches a predetermined pressure, the oscillation portion is opened to release the pressure in the dredging cavity; when the pressure in the dredging cavity is less than the predetermined pressure, the oscillation portion is closed, so that the pressure in the dredging cavity increases, and the fluid in the dredging cavity is pressurized in a cycle of depressurization and pressurization, which causes the material blocking the water inlet hole to oscillate and enter the flower pipe.

[0011] In one possible implementation, the first sealing portion includes:

[0012] A sealing plate is adapted to the inner cavity of the flower tube, and the side wall of the sealing plate abuts against and is fixed to the inner wall of the flower tube, so that the sealing plate seals the inner wall of the flower tube.

[0013] An insert is provided on the sealing plate, and one end of the injection tube is inserted into the insert.

[0014] In one possible implementation, the insert includes a variable diameter section and a constant diameter section, the constant diameter section being connected to the sealing plate, and the inner diameter of the variable diameter section being set from small to large as it approaches the sealing plate and moves away from the sealing plate.

[0015] The end of the injection tube is provided with an insertion section, which is adapted to the variable diameter section and is inserted into the variable diameter section.

[0016] In one possible implementation, the injection tube passes through the second sealing part, and the portion of the injection tube located within the unblocking cavity has multiple injection holes.

[0017] In one possible implementation, the second sealing part includes a sealing post with a diameter the same as the inner diameter of the perforated tube, the sealing post being inserted into the perforated tube, and the sealing post being spaced apart from the sealing plate;

[0018] The sealing column has a hole at its center, and the injection tube is inserted into the hole.

[0019] In one possible implementation, the insertion hole includes a large-diameter hole and a small-diameter hole, the large-diameter hole being connected to the small-diameter hole, and the small-diameter hole being located at one end of the large-diameter hole near the sealing plate;

[0020] The vibrating part is slidably disposed in the insertion hole. In its natural state, the vibrating part blocks the small diameter hole, and the vibrating part can open the small diameter hole due to sliding, so that the external space of the unblocking cavity, the small diameter hole, the large diameter hole and the second sealing part is connected.

[0021] In one possible implementation, the oscillation section includes:

[0022] The plug is cylindrical, with a through hole in the middle. The injection tube is inserted into the through hole, and the plug is slidably disposed in the small-diameter hole.

[0023] A connecting block, in the shape of a cross, is located on one side of the plug, and the end of the connecting block abuts against the inner wall of the large-diameter hole;

[0024] A guide rod passes through the sealing post opposite to the small-diameter hole and is fixed to the connecting block;

[0025] A return spring is sleeved on the outside of the guide rod. One end of the return spring is connected to the sealing post, and the other end of the return spring is connected to the connecting block. When the return spring is in its natural state, the plug is inserted into the small-diameter hole.

[0026] One possible implementation also includes:

[0027] A fixing member is provided through which the injection tube passes, and the fixing member is used to limit the position of the injection tube.

[0028] In one possible implementation, the fastener includes:

[0029] A fixing tube is inserted into the large-diameter hole. The outer wall of the fixing tube is fixedly connected to the inner wall of the sealing column. The fixing tube is provided with multiple rows of holes, which are evenly arranged and the centers of each row of holes form a circle.

[0030] A connecting tube is provided on one side of the fixed tube. The injection tube passes through the fixed tube and the connecting tube. The connecting tube has a connecting hole, and a bolt is screwed into the connecting hole. The bolt abuts against the injection tube, thereby fixing the injection tube to the connecting tube.

[0031] In one possible implementation, the top end of the injection tube is provided with a connector for connection to a fluid supply device;

[0032] The connector is tubular, and the inner cavity of the connector is hourglass-shaped;

[0033] The top end of the injection tube is provided with a connecting section, the shape of which is adapted to the connector, and the connecting section is inserted into the connector.

In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0055] The fluid oscillation type pipe unblocking device provided by the present invention will now be described.

[0056] Please refer to the following: Figure 1 and Figure 2The fluid oscillation type pipe unblocking device is used to unblock the water inlet 401 of the pipe 4 inserted in the horizontal drainage and pressure reduction hole. It includes a first sealing part 1, a second sealing part, an injection tube 3, and an oscillation part. The first sealing part 1 is located inside the pipe 4 near one end, and is sealed to the pipe 4. The second sealing part is located opposite the end of the first sealing part 1, and is located inside the pipe 4 near the other end, and is also sealed to the pipe 4. The inner cavity of the pipe 4 between the first sealing part 1 and the second sealing part is designated as an unblocking cavity. The injection tube 3 is partially inserted into the unblocking cavity and is used to inject fluid into the unblocking cavity. The oscillating part is located on the second sealing part. When the fluid pressure in the unblocking cavity reaches the preset pressure, the oscillating part opens to release the pressure in the unblocking cavity; when the pressure in the unblocking cavity is less than the preset pressure, the oscillating part closes, which increases the pressure in the unblocking cavity. Through the repeated cycle of fluid pressure increase, decrease and increase in the unblocking cavity, the material blocking the water inlet hole 401 is oscillated, causing the blockage to enter the flower pipe 4.

[0057] The beneficial effects of the fluid oscillation type pipe unblocking device provided in this embodiment are as follows: Compared with the prior art, the fluid oscillation type pipe unblocking device provided in this embodiment forms an unblocking cavity by setting a first sealing part 1 and a second sealing part. By setting an injection tube 3 and an oscillation part, when fluid is injected into the unblocking cavity, oscillation is formed in the unblocking cavity, so that the debris blocking the water inlet hole 401 enters the pipe 4 and is discharged out of the pipe 4 with the fluid, thereby achieving the purpose of unblocking the water inlet hole 401 of the pipe 4.

[0058] It is worth noting that the increase in pressure inside the unblocking cavity will not push the debris blocking the water inlet 401 out of the perforated pipe 4, because the perforated pipe 4 is located deep in the stratum. The pressure of water on the perforated pipe 4 or the pressure of the collapsed stratum on the perforated pipe 4 is extremely high. This pressure is greater than the pressure of the fluid inside the unblocking cavity. Therefore, the increase in pressure in the unblocking cavity will not affect the entry of impurities into the perforated pipe 4.

[0059] like Figure 1 In this design, the first sealing part 1 includes a sealing plate 101 and a insert 102. The sealing plate 101 is adapted to the inner cavity of the perforated tube 4, and the side wall of the sealing plate 101 abuts against and is fixed to the inner wall of the perforated tube 4, thus sealing the sealing plate 101 with the inner wall of the perforated tube 4. The insert 102 is disposed on the sealing plate 101, and one end of the injection tube 3 is inserted into the insert 102. The sealing plate 101 blocks one end of the perforated tube 4, and the insert 102 facilitates the fixation of the injection tube 3.

[0060] As a preferred technical solution, the insert 102 includes a variable diameter section 104 and a constant diameter section 103. The constant diameter section 103 is connected to the sealing plate 101. The inner diameter of the variable diameter section 104 increases from the area near the sealing plate 101 to the area away from the sealing plate 101. The end of the injection tube 3 is provided with an insertion section 301, which is adapted to the variable diameter section 104 and is inserted into the variable diameter section 104. The variable diameter section 104 facilitates the insertion of the insertion section 301 of the injection tube 3 into the insert 102, thereby facilitating the fixation of the injection tube 3.

[0061] like Figure 1 As shown, the injection tube 3 passes through the second sealing part, and the portion of the injection tube 3 located inside the unblocking cavity is provided with multiple injection holes 302. The multiple injection holes 302 facilitate the injection of fluid into the unblocking cavity by the injection tube 3. The fluid here can refer to either liquid or gas.

[0062] like Figure 2 As shown, the second sealing part includes a sealing post 2, the diameter of which is the same as the inner diameter of the perforated tube 4. The sealing post 2 is inserted into the perforated tube 4, and is spaced apart from the sealing plate 101. An insertion hole is provided at the center of the sealing post 2, and the injection tube 3 is inserted into the insertion hole. The sealing post 2 seals the other end of the perforated tube 4, thereby forming a sealed drainage cavity within the perforated tube 4.

[0063] As a preferred technical solution, the insertion hole includes a large-diameter hole 201 and a small-diameter hole 202, with the large-diameter hole 201 connected to the small-diameter hole 202 located at one end of the large-diameter hole 201 near the sealing plate 101. A vibrating part is slidably disposed within the insertion hole. In its natural state, the vibrating part blocks the small-diameter hole 202, and the vibrating part can open the small-diameter hole 202 due to sliding, thus connecting the unblocking cavity, the small-diameter hole 202, the large-diameter hole 201, and the external space of the second sealing part.

[0064] Specifically in this embodiment, combined with Figure 1 , Figure 3 and Figure 4 As shown, the oscillating section includes a plug 5, a connecting block 501, a guide rod 502, and a return spring. The plug 5 is cylindrical with a through hole in its center, into which the injection tube 3 is inserted. The plug 5 is slidably positioned within the small-diameter hole 202. The connecting block 501 is cross-shaped and located on one side of the plug 5, with its end abutting against the inner wall of the large-diameter hole 201. When the pressure within the unblocking cavity causes the plug 5 to slide out of the small-diameter hole 202, the fluid within the unblocking cavity can flow through the gap between the connecting block 501 and the large-diameter hole 201 and then into the other side of the plug 5.

[0065] The guide rod 502 passes through the sealing post 2 opposite to the small diameter hole 202 and is fixed on the connecting block 501. The return spring is sleeved on the outside of the guide rod 502. One end of the return spring is connected to the sealing post 2, and the other end of the return spring is connected to the connecting block 501. When the return spring is in its natural state, the plug 5 is inserted into the small diameter hole 202.

[0066] Here, when the block 5 opens the small diameter hole 202, the speed at which the fluid in the unblocking cavity is discharged out of the unblocking cavity is greater than the speed at which the injection tube 3 is injected into the unblocking cavity, causing the pressure in the unblocking cavity to drop rapidly, and thus the block 5 is reset under the action of the reset spring.

[0067] like Figure 1 As shown, the fluid oscillation type pipe unblocking device of the present invention also includes a fixing member 6, through which the injection tube 3 passes and is fixed. The fixing member 6 is used to limit the injection tube 3.

[0068] Combined Figure 5 and Figure 6 As shown, the fixing component 6 includes a fixing tube 601 and a connecting tube 602. The fixing tube 601 is inserted into the large-diameter hole 201, and its outer wall is fixedly connected to the inner wall of the sealing column 2. The fixing tube 601 has multiple rows of holes 603, which are evenly arranged and their centers form a circle. The connecting tube 602 is located on one side of the fixing tube 601. The injection tube 3 passes through the fixing tube 601 and the connecting tube 602, and the connecting tube 602 has a connecting hole 604. A bolt is screwed into the connecting hole 604, and the bolt abuts against the injection tube 3, thus fixing the injection tube 3 to the connecting tube 602. The sealing column 2 is connected to the perforated tube 4, the fixing tube 601 is connected to the sealing column 2, and the connecting tube 602 is connected to the fixing tube 601. The injection tube 3 is relatively fixed to the connecting tube 602, thereby fixing the injection tube 3. The rows of holes 603 are provided to facilitate the discharge of impurities and fluid from the injection chamber.

[0069] Finally, the top end of the injection tube 3 is provided with a connector 7, which is used to connect to a fluid supply device. The connector 7 is tubular, and its inner cavity is hourglass-shaped. The top end of the injection tube 3 is provided with a connecting section 303, the shape of which is adapted to the connector 7, and the connecting section 303 is inserted into the connector 7. The connector 7 facilitates the supply of fluid to the injection tube 3 by an external supply device.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
