Description

Technical Field

[0001] This invention relates to the field of horizontal directional drilling guidance technology, and more specifically, to a horizontal directional drilling guidance structure with surface cleaning effect. Background Technology

[0002] Horizontal directional drilling rigs are construction machines used to lay various underground utilities (pipelines, cables, etc.) without excavating the ground surface. They are widely used in the construction of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, and oil.

[0003] The horizontal directional drilling guide mechanism is a bend joint in the drilling rig with a certain bending angle. The bend joint and the drill rod are at a certain angle instead of being a straight line, so as to change the drilling direction during the drilling process and achieve the guiding function.

[0004] During directional drilling, the drilling fluid is a viscous liquid mixture of water and bentonite. Therefore, if the mud residue adhering to the surface of the elbow joint is not cleaned in time after the drilling task is completed, it can easily cause corrosion of the elbow joint and accelerate its aging. However, currently, after the drilling task is completed, most of the cleaning is done manually using tools such as brushes and high-pressure water guns. The cleaning process requires repeated rinsing and scraping, which is physically demanding, time-consuming, and inefficient. Furthermore, when continuous drilling operations are required, if the elbow joint needs to be cleaned quickly for reuse, manual cleaning may not be fast enough, causing equipment to be unable to continue and affecting the construction progress.

[0005] In view of this, we propose a horizontal directional drilling guide structure with surface cleaning effect. Summary of the Invention

One end of the inner processing cavity penetrates the end of the airtight insulating column; The drainage tube is equipped with a one-way vent valve; A passively insulated plunger is sealed and slidable in the inner processing cavity. A first return spring is connected to the end of the passively insulated plunger, and the end of the first return spring away from the passively insulated plunger is connected to the end of the inner processing cavity. A trigger ring is fixedly attached to the side wall of the passively insulated plunger, and the side wall surface of the trigger ring is flush with the side wall surface of the passively insulated plunger. The placement port is connected to the inner processing cavity, and an insulating plug is sealed and inserted inside the placement port, with the end of the insulating plug connected to the side wall of the airtight insulating column. A trigger spring is connected to one end of the insulating plug that extends into the cavity of the placement port; One end of the guide channel is connected to the end of the inner processing cavity, and the other end passes through the end of the airtight insulating column; The drainage tube is fixedly connected to the end of the airtight cylinder seat.

The one-way exhaust valve is also located in the inner cavity of the airtight cylinder seat. When the first return spring is in its initial relaxed state, the free end of the trigger spring elastically abuts against the side wall surface of the trigger coil.

[0014] As an optional solution to the technical solution of this invention, the alarm is connected to the end of the handle; Both the trigger spring and the trigger coil are electrically connected to the alarm. When the free end of the trigger spring contacts the trigger coil, the series circuit consisting of the trigger spring, the trigger coil, and the alarm is activated.

[0015] As an optional solution to the technical solution of this invention, the flow guide includes a diversion pipe whose middle part is connected to the inside of the solid tube shell and whose two ends extend from the inside of the solid tube shell; The shunt pipe is fixedly connected to a connecting pipe located inside the solid pipe shell, and the end of the connecting pipe away from the shunt pipe is connected to the column hole.

[0016] As an optional solution to the technical solution of this invention, the capsule portion includes a strip-shaped elastic capsule, and the bottom of the strip-shaped elastic capsule is provided with an elastic thin-walled portion; The top of the strip-shaped elastic bladder is fixedly connected to an injection tube; The base arc plate is located between the strip-shaped elastic bladder and the diversion pipe, and the end of the injection pipe away from the strip-shaped elastic bladder passes through the base arc plate and is fixedly connected to the diversion pipe; The side wall surface of the rotating seat is provided with positioning grooves that are adapted to each strip-shaped elastic bladder at the corresponding position of each bladder part, and each strip-shaped elastic bladder can be movably inserted into its corresponding positioning groove.

[0017] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. After removing the head sealing plate and side sealing plate from the solid tube shell in the base assembly, insert both ends of the water flow pipe in the nozzle assembly into the inner cavities of the two solid tube shells respectively. Then, as the propulsion unit is continuously screwed into the column hole through the external thread on the airtight insulating column, the moving airtight insulating column continuously injects gas into the bladder part through the guide part. After the air pressure inside the strip-shaped elastic bladder in the bladder part increases, it drives the elastic thin-walled part to elastically bulge outward, and causes the side of the strip-shaped elastic bladder away from the elastic thin-walled part to apply pressure to the surface of the base arc plate, causing the base arc plate to move in the opposite direction. The bolt heads used to fix the base plate apply reverse pressure, which increases the friction force that the bolts need to overcome when they loosen and reverse during the cleaning process of the elbow joint body when encountering vibrations generated by the high-pressure water sprayed onto the elbow joint body surface by the nozzle assembly. This improves the installation firmness of the base assembly and effectively prevents the nozzle assembly from shaking due to loose bolts in the base assembly during the cleaning of the elbow joint body. This helps to ensure the constantness of parameters such as nozzle angle and spray pressure during the cleaning process, and improves the cleaning effect on the residues attached to the elbow joint body surface.

[0018] 2. As the propulsion unit is continuously screwed into the column hole, the end of the contact head abuts against the side wall surface of the water flow pipe end in the nozzle assembly. Simultaneously, as the movable airtight insulating column continuously injects gas into the bladder through the guide section, it also simultaneously pressurizes the airtight telescopic mechanism. As the retracting rod retracts into the airtight cylinder seat, the airtight piston, moving synchronously with the retracting rod, continuously compresses the gas inside the airtight cylinder seat. With the increasing air pressure inside the airtight telescopic mechanism, the clamping effect of the locking component on the water flow pipe end in the nozzle assembly is enhanced. Furthermore, the external thread is pressed more tightly against the surface of the threaded groove, increasing the frictional force required to overcome when the locking component loosens and reverses. This effectively prevents the locking component from reversing and loosening due to vibration during cleaning of the elbow joint body, thus improving the fastening effect of the nozzle assembly.

[0019] 3. Furthermore, the compressed airtight telescopic mechanism can continuously absorb the vibration energy from the nozzle assembly through its elastic deformation during the cleaning process, effectively reducing the amplitude of vibration transmitted to the propulsion unit, which helps to further improve the anti-loosening effect of the locking components during the cleaning process.

[0020] 4. As the airtight telescopic mechanism is continuously compressed by the moving propulsion unit, the increasing air pressure inside the column hole pushes the passive insulating plunger to move. The moving passive insulating plunger drives the trigger ring, which was originally in contact with the free end of the trigger spring, to move, causing the trigger ring to separate from the trigger spring. The moving passive insulating plunger also injects more gas into the airtight cylinder seat of the airtight telescopic mechanism through the guide channel, which further increases the elastic clamping force of the airtight telescopic mechanism on the water pipe, and also makes the external threaded part press more tightly against the surface of the threaded groove. Furthermore, this helps to further improve the fastening effect of the locking component on the surface of the nozzle assembly cleaning elbow joint during the process of removing residues.

[0021] 5. During the cleaning process of residues adhering to the surface of the elbow joint, if the bolts fixing the base plate or the locking components of the nozzle assembly become loose, causing a drop in air pressure between the airtight insulating column and the contact end in the column hole, the active passive insulating plunger will drive the trigger ring to contact the free end of the trigger spring again under the action of the first reset spring, triggering the alarm to open. The alarm will then send an alarm signal to the outside world to remind the operator to tighten the bolts and locking components in time. This prevents the high-pressure nozzle in the nozzle assembly from changing the spray angle, spray pressure, and other parameters of the residues adhering to the elbow joint surface due to shaking during the cleaning process, thus ensuring the cleaning effect on the residues adhering to the elbow joint surface.

[0022] 6. The nozzle assembly is driven to rotate by the end base structure, and then the rotating nozzle assembly sprays high-pressure water to achieve efficient and thorough cleaning of mud residues adhering to the surface of the horizontal directional drilling guide structure, resulting in good cleaning effect.

The capsule assembly includes a flow guide that communicates with the column hole and several capsule parts that communicate with the flow guide and are disposed at the bottom of the base assembly.

[0037] Reference Figures 1 to 6 The present invention provides a horizontal directional drill guide structure with surface cleaning effect. The end base structure includes a bottom ring seat 405 that is sleeved and fixed to the outer periphery of the end of the elbow body 100. The bottom ring seat 405 is fixedly connected to the outer periphery of the end of the elbow body 100 by welding. The bottom ring seat 405 is rotatably sleeved with a rotating ring seat 404.

[0038] Reference Figures 1 to 4 This invention provides a horizontal directional drilling guide structure with surface cleaning effect, wherein the nozzle assembly includes a water flow pipe 501; Multiple high-pressure nozzles 502 are evenly fixedly connected to the side wall of the water flow pipe 501.

[0039] After completing the drilling task, the two ends of the elbow joint body 100 are respectively mounted on the fixed frame. The two ends of the elbow joint body 100 can be fixed by manual pressing or clamps. Then, the external soft water pipe is connected to the water inlet on the water flow pipeline 501. Next, water is pumped into the water flow pipeline 501 through the soft water pipe. Then, the nozzle assembly is driven to rotate by manual means through the end base structure. Subsequently, the high-pressure nozzle 502 in the rotating nozzle assembly sprays high-pressure water to achieve efficient and thorough cleaning of the mud residue attached to the surface of the horizontal directional drilling guide structure. The cleaning effect is good.

[0040] Reference Figures 1 to 4 , Figure 7 , Figure 8 The present invention provides a horizontal directional drill guide structure with surface cleaning effect, wherein the base assembly includes a base arc plate 403 that is bolted to a swivel seat 404; A solid pipe shell 401 is connected to the base arc plate 403. A column hole is set on the side wall of the solid pipe shell 401 and communicates with the inner cavity of the solid pipe shell 401. The two ends of the water flow pipe 501 can be movably inserted into the inner cavities of the two solid pipe shells 401 respectively. When inserting the two ends of the water flow pipe 501 into the two solid pipe shells 401 respectively, first insert one end of the water flow pipe 501 into the inner cavity of one of the solid pipe shells 401. Then, pull the water flow pipe 501 so that the other end of the water flow pipe enters between the two solid pipe shells 401 and is aligned with the inner cavity of the other solid pipe shell 401. Then insert the other end of the water flow pipe 501 into the inner cavity of the other solid pipe shell 401. The solid tube shell 401 has a detachable sealing connection at both ends with a head sealing plate, and the two head sealing plates respectively cover the openings at both ends of the solid tube shell 401. The solid casing 401 has a detachable side sealing plate connected to its side wall, which covers the opening at the end of the borehole (not shown in the figure). When the equipment is performing a drilling task, both the head sealing plate and the side sealing plate are connected to the solid casing 401. The head sealing plate covers the openings at both ends of the solid casing 401, and the side sealing plates cover the opening at the end of the borehole. The head sealing plate and the side sealing plate prevent impurities from entering the inner cavity of the solid casing 401 and the interior of the borehole during drilling. The detachable connection methods include, but are not limited to, bolt connections and snap-fit ​​connections.

[0041] Reference Figures 1 to 4 , Figure 7 , Figure 8The present invention provides a horizontal directional drilling guide structure with surface cleaning effect. The guide part includes a diversion pipe 416 whose middle part is connected to the inside of the solid pipe shell 401 and whose two ends extend from the inside of the solid pipe shell 401. The two ends of the water flow pipe 501 can be movably inserted into the inner cavity of the two solid pipe shells 401 respectively. A connecting pipe 426 located inside the solid pipe shell 401 is fixedly connected to the diverter pipe 416, and the end of the connecting pipe 426 away from the diverter pipe 416 is connected to the column hole.

[0042] Reference Figure 7 and Figure 8 The present invention provides a horizontal directional drill guide structure with surface cleaning effect. The capsule part includes a strip-shaped elastic capsule 402, and the bottom of the strip-shaped elastic capsule 402 is provided with an elastic thin-walled part 418. The top of the strip-shaped elastic capsule 402 is fixedly connected to an injection tube 417; The base arc plate 403 is located between the strip-shaped elastic bladder 402 and the diversion pipe 416, and the end of the injection pipe 417 away from the strip-shaped elastic bladder 402 passes through the base arc plate 403 and is fixedly connected to the diversion pipe 416. The side wall surface of the rotating seat 404 is provided with positioning grooves that are adapted to each strip-shaped elastic bladder 402 at the corresponding positions of each bladder part, and each strip-shaped elastic bladder 402 can be movably inserted into its corresponding positioning groove.

[0043] After removing the head and side sealing plates from the solid tube shell 401 in the base assembly, insert both ends of the water flow pipe 501 in the nozzle assembly into the inner cavities of the two solid tube shells 401 respectively. Then, as the propulsion unit is continuously screwed into the column hole through the external thread 408 on the airtight insulating column 406, the movable airtight insulating column 406 continuously injects gas into the bladder section through the guide section. The increased air pressure inside the strip-shaped elastic bladder 402 in the bladder section drives the elastic thin-walled section 418 to elastically bulge outwards, causing the side of the strip-shaped elastic bladder 402 away from the elastic thin-walled section 418 to apply pressure to the surface of the base arc plate 403, thus causing the base... The arc plate 403 applies reverse pressure to the bolt head portion of the bolt used to fix the base plate 403, thereby increasing the friction force that the bolt needs to overcome when it loosens and reverses due to the vibration generated when the high-pressure water is sprayed onto the surface of the elbow body 100 during the cleaning process. This improves the installation firmness of the base assembly and effectively prevents the nozzle assembly from shaking due to the loosening of the bolts in the base assembly during the cleaning of the elbow body 100. This helps to ensure the constantness of parameters such as nozzle angle and spray pressure during the cleaning process and improves the cleaning effect on the residues attached to the surface of the elbow body 100.

[0044] Reference Figures 1 to 4 , Figure 7 , Figure 9 The present invention provides a horizontal directional drilling guide structure with surface cleaning effect, and the propulsion unit further includes an external threaded portion 408 disposed on the end side wall of the airtight insulating column 406; A handle is connected to one end of the airtight insulating column 406 near the external thread 408; Both the airtight insulating column 406 and the abutting end 415 are sealed and slide inside the column hole; The end opening of the column hole is provided with a threaded groove that works in conjunction with the external threaded part 408.

[0045] Reference Figure 7 , Figure 9 and Figure 10 The present invention provides a horizontal directional drill guide structure with surface cleaning effect. The airtight telescopic mechanism includes an airtight cylinder seat 419 with a fixed end connected to an airtight insulating column 406 at the end away from the handle. An airtight piston 420 is sealed and slidably installed in the inner cavity of the airtight cylinder seat 419. An advance / retracting rod 424 is connected to the airtight piston 420, and the end of the advance / retracting rod 424 away from the airtight piston 420 passes through the end of the airtight cylinder seat 419 away from the airtight insulating column 406 and is connected to the abutment end 415. A second return spring 414 is connected to the end of the airtight piston 420 away from the forward / reverse rod 424, and the end of the second return spring 414 away from the airtight piston 420 is connected to the end of the inner cavity of the airtight cylinder seat 419. The airtight telescopic mechanism also includes several directional guide rods 423 that are movably inserted into the end of the airtight insulating column 406, and the end of the directional guide rod 423 away from the airtight insulating column 406 is connected to the abutment end 415.

[0046] As the propulsion unit is continuously screwed into the column hole, the end of the contact end 415 abuts against the side wall surface of the end of the water flow pipe 501 in the nozzle assembly. While the movable airtight insulating column 406 continuously injects gas into the bladder through the guide part, the movable airtight insulating column 406 also simultaneously presses the airtight telescopic mechanism. As the retracting rod 424 continuously retracts into the airtight cylinder seat 419, the airtight piston 420, which moves synchronously with the retracting rod 424, continuously squeezes and compresses the gas inside the airtight cylinder seat 419. As the air pressure inside the airtight telescopic mechanism continuously increases, the clamping effect of the locking component on the end of the water flow pipe 501 in the nozzle assembly is improved. At the same time, the external thread 408 is pressed more tightly against the surface of the thread groove, which increases the friction force that the locking component needs to overcome when it loosens and reverses. This effectively prevents the locking component from reversing and loosening due to vibration during the cleaning of the elbow body 100, thus improving the fastening effect of the nozzle assembly.

[0047] Furthermore, the compressed airtight telescopic mechanism can continuously absorb the vibration energy from the nozzle assembly through its elastic deformation during the cleaning process, effectively reducing the amplitude of vibration transmitted to the propulsion unit, which helps to further improve the anti-loosening effect of the locking components during the cleaning process.

[0048] Example 2, the difference between this example and Example 1 is: (Refer to...) Figures 1 to 4 , Figure 7 , Figure 9 The present invention provides a horizontal directional drilling guide structure with surface cleaning effect. The propulsion unit also includes an alarm 407, a drainage pipe 421, a mounting port provided on the side wall of the airtight insulating column 406, and an inner processing cavity and a guide channel 422 provided inside the airtight insulating column 406. The alarm 407 is connected to the end of the handle, and the alarm 407 is preferably an audible and visual alarm. One end of the inner processing cavity penetrates the end of the airtight insulating column 406; A one-way exhaust valve 427 is provided on the drainage tube 421; A passively insulated plunger 410 is sealed and slidable in the inner processing cavity. A first return spring 413 is connected to the end of the passively insulated plunger 410, and the end of the first return spring 413 away from the passively insulated plunger 410 is connected to the end of the inner processing cavity. A trigger ring 412 is fixedly attached to the side wall of the passive insulating plunger 410, and the side wall surface of the trigger ring 412 is flush with the side wall surface of the passive insulating plunger 410. The placement port is connected to the inner processing cavity, and an insulating plug 425 is sealed and inserted into the placement port, with the end of the insulating plug 425 connected to the side wall of the airtight insulating column 406. A trigger spring 411 is connected to one end of the insulating plug 425 that extends into the inner cavity of the placement port; One end of the guide channel 422 is connected to the end of the inner processing cavity, and the other end passes through the end of the airtight insulating column 406; The drainage tube 421 is fixedly connected to the end of the airtight cylinder seat 419. One end of the drainage tube 421 is sealed and inserted into the end opening of the guide channel 422, and the other end extends into the inner cavity of the airtight cylinder seat 419. The one-way exhaust valve 427 is also located in the inner cavity of the airtight cylinder seat 419. The function of the one-way exhaust valve 427 is that when the active passive insulating plunger 410 squeezes and compresses the gas inside the inner treatment cavity, the one-way exhaust valve 427 controls the airflow to flow only into the airtight cylinder seat 419. When the airtight piston 420 compresses the gas inside the airtight cylinder seat 419, the airflow cannot enter the guide channel 422 through the one-way exhaust valve 427. When the first return spring 413 is in the initial relaxed state, the free end of the trigger spring 411 elastically abuts against the side wall surface of the trigger coil 412. Both the trigger spring 411 and the trigger coil 412 are electrically connected to the alarm 407. When the free end of the trigger spring 411 contacts the trigger coil 412, the series circuit consisting of the trigger spring 411, the trigger coil 412 and the alarm 407 is activated.

[0049] As the airtight telescopic mechanism is continuously squeezed by the moving propulsion unit, the ever-increasing air pressure inside the column hole pushes the passive insulating plunger 410 to move. The moving passive insulating plunger 410 drives the trigger ring 412, which was originally in contact with the free end of the trigger spring 411, to move, causing the trigger ring 412 to separate from the trigger spring 411. The moving passive insulating plunger 410 will also inject gas into the airtight cylinder seat 419 in the airtight telescopic mechanism through the guide channel 422, which further increases the elastic clamping force of the airtight telescopic mechanism on the water flow pipeline 501, and also makes the external thread part press more tightly against the surface of the thread groove part. In this way, it helps to further improve the fastening effect of the locking component on the surface of the nozzle assembly cleaning elbow joint body 100 when residues are attached to it.

[0050] During the cleaning process of residues adhering to the surface of the elbow body 100, if the bolts fixing the base arc plate 403 or the locking components of the nozzle assembly become loose, causing a drop in air pressure between the airtight insulating column 406 and the contact end 415 in the column hole, the active passive insulating plunger 410 drives the trigger ring 412 to contact the free end of the trigger spring 411 again under the elastic force of the first reset spring 413, triggering the alarm 407 to open. The alarm 407 then sends an alarm signal to the outside world to remind the operator to tighten the bolts and locking components again in time. This prevents the high-pressure nozzle 502 in the nozzle assembly from changing the spray cleaning angle, spray pressure, and other parameters of the residues adhering to the surface of the elbow body 100 due to shaking of the nozzle assembly during cleaning, thus ensuring the cleaning effect on the residues adhering to the surface of the elbow body 100.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
