Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grouting devices for water conservancy and hydropower engineering construction, and more specifically, it relates to a grouting device for water conservancy and hydropower engineering construction. Background Technology
[0002] In the field of water conservancy and hydropower engineering construction, grouting equipment is a key piece of equipment whose performance and reliability directly affect the quality and efficiency of the project. However, the grouting equipment currently on the market still has serious technical defects in practical applications. These problems not only affect construction efficiency, but may also lead to equipment damage and safety hazards.
[0003] The primary problem is the fragility of the mixing system. Existing technologies generally use a mixing rod connected to a blade to mix the slurry, ensuring its fluidity and preventing solidification. However, the connection structure between the mixing rod and the motor output is too simple and lacks an effective protection mechanism. When the slurry is too viscous or contains large particles, the blade may encounter excessive resistance, which can easily lead to breakage of the mixing rod and blade, or even overload damage to the motor. More seriously, existing equipment generally lacks the ability to flexibly adjust the triggering mechanism of the protective device according to different slurry characteristics. This rigid design not only cannot adapt to changing construction needs, but also greatly increases the risk of equipment damage and downtime, seriously affecting construction progress and cost control.
[0004] Secondly, the instability of the protection mechanism adjustment is also a prominent problem. Although some improved equipment has introduced an adjustable protection trigger mechanism, allowing operators to set the resistance threshold of the motor idling according to the characteristics of the grout, the design of this adjustment mechanism still has serious defects. Because the grouting equipment will generate continuous high-speed rotation and violent vibration during operation, the simple adjustment structure is prone to loosening or displacement. This means that the carefully adjusted trigger mechanism may change quietly during construction, resulting in protection failure or over-triggering. Not only will it fail to achieve the expected protection effect, but it may also trigger a series of chain problems, such as frequent shutdowns and grout waste, which seriously affect construction efficiency and quality.
[0005] Finally, the difficulty of equipment cleaning cannot be ignored. The storage tank structure of existing grouting devices is generally simple and lacks an effective self-cleaning mechanism. This means that after each use, operators need to manually clean the inside of the storage tank, which is a time-consuming and labor-intensive task. In large-scale water conservancy and hydropower projects, frequent manual cleaning not only reduces the efficiency of equipment use, but also increases labor intensity and labor costs. More importantly, manual cleaning is difficult to guarantee the thoroughness and consistency of cleaning. Residual grout may affect the quality of grout used next time, and may even lead to serious problems such as equipment pipeline blockage. Utility Model Content

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a grouting device for water conservancy and hydropower engineering construction, which has the following beneficial effects:
[0019] 1. The innovative design of the protective device cleverly solves the problem of the fragility of the mixing system. Through the precise coordination of the rotating sleeve, linkage groove, moving groove, protective sleeve, linkage spring, moving block, linkage frame, and linkage block, an adjustable protective mechanism is formed. When the mixing rod encounters excessive resistance, the linkage frame can slide out from the linkage groove, and the linkage spring is compressed by the linkage block and moving block, allowing the motor to idle, effectively preventing the mixing rod from breaking and the motor from being overloaded. More importantly, this design allows operators to flexibly adjust the trigger threshold according to different slurry characteristics. By rotating the rotating sleeve, the position of the moving block can be changed, thereby adjusting the preload of the linkage spring and achieving precise control over the triggering difficulty. This flexible adjustment mechanism not only improves the adaptability of the equipment but also greatly reduces the risk of equipment damage and downtime, significantly improving construction efficiency and safety.
[0020] 2. The innovative design of the locking mechanism solves the problem of unstable adjustment of the protective mechanism. Through the ingenious cooperation of the straight rod, locking rod, locking sleeve, unlocking sleeve, unlocking hole, and arc groove, a reliable locking system is formed. The operator can rotate the unlocking sleeve to make the locking rod pass through the unlocking hole, and then use the cooperation of the arc groove and the straight rod to fix the locking sleeve. This design allows for quick unlocking when adjustments are needed. After the locking sleeve is reset, the limiting effect of the locking sleeve on the locking rod, combined with the tension of the return spring, further enhances the stability of the entire system and achieves complete locking of the rotating sleeve. This multi-locking mechanism greatly improves the reliability of the equipment in complex construction environments and ensures that the protective device can always remain at the preset trigger threshold.
[0021] 3. The design of the cleaning device effectively solves the problem of difficult equipment cleaning. Through the precise coordination of the output pipe, input pipe, delivery pump, and nozzles, a highly efficient cleaning system is formed. Multiple spherical nozzles are installed under the tank cover and connected to the delivery pump through a connecting pipe. This allows water from the external water storage device to be sprayed evenly into the storage tank. Combined with the rotation of the stirring rod and blades, all-round mechanized cleaning is achieved. This design not only greatly simplifies the cleaning operation but also significantly improves the cleaning efficiency and thoroughness. After cleaning, simply open the valve to drain the cleaned water. The whole process is simple and quick, which not only improves the efficiency of equipment use but also ensures the cleanliness of the storage tank after each use, effectively preventing residual slurry from affecting the next use and extending the service life of the equipment.

The rotating sleeve 5 is rotatably mounted on the outside of the protective sleeve 8. The linkage groove 6 is located on the outside of one end of the stirring rod 2, the moving groove 7 is located on the inside of the protective sleeve 8, one end of the protective sleeve 8 is detachably connected to the output end of the motor 4, and both ends of the linkage spring 9 are connected to the linkage block 12 and the moving block 10, respectively. The movable part is installed in the movable slot 7. One end of the linkage frame 11 is inserted into the linkage slot 6. The linkage frame 11 is movably set in the movable slot 7. One side of the linkage block 12 is in contact with the linkage frame 11. A locking mechanism is provided on the outside of the protective sleeve 8. The locking mechanism includes a straight rod 13, a locking rod 14, a locking sleeve 15, an unlocking sleeve 16, an unlocking hole 17, and an arc groove 18. The straight rod 13 is fixedly connected to one side of the locking sleeve 15. The locking rod 14 is fixedly connected to one end of the straight rod 13. The locking sleeve 15 is slidably sleeved on the outside of the protective sleeve 8. The unlocking sleeve 16 is rotatably sleeved on the outside of the protective sleeve 8. The arc groove 18 is opened on the unlocking sleeve 16. The unlocking hole 17 is opened at one end of the arc groove 18. A cleaning device is installed in the storage tank 1.
[0032] The storage tank 1 is detachably provided with a tank cover 19 at the top, and a feed pipe 20 is fixedly provided on the tank cover 19. The feed pipe 20 is detachably provided with a feed cover 21 at the top.
[0033] Multiple blades 22 are fixedly provided on the outside of the stirring rod 2, and multiple through holes 23 are provided on the blades 22.
[0034] The bottom of the storage tank 1 is fixedly connected to a discharge pipe 24, one end of which is equipped with a valve 25, and the other end of the valve 25 is connected to a discharge pipe 26.
[0035] Multiple locking rods 27 are slidably provided on the rotating sleeve 5, and multiple locking grooves 28 are opened on the outer wall of the protective sleeve 8. A return spring 29 is provided on the outer side of the rotating sleeve 5. One end of the locking rod 27 is connected to the outer wall of the rotating sleeve 5 through the return spring 29, and the other end of the locking rod 27 is inserted into the locking groove 28. A movable spring 30 is connected to one side of the locking sleeve 15, and the other end of the movable spring 30 is in contact with the unlocking sleeve 16.
[0036] In this embodiment, when the trigger threshold needs to be adjusted according to the characteristics of the slurry, the unlocking sleeve 16 is first rotated forward. The unlocking sleeve 16 drives the arc groove 18 and the unlocking hole 17 to rotate. When the unlocking hole 17 rotates to a position concentric with the locking rod 14 and the straight rod 13, the locking sleeve 15 is pushed. The locking sleeve 15 will drive the locking rod 14 to slide through the straight rod 13, so that the locking rod 14 gradually enters the unlocking hole 17. The locking sleeve 15 and the unlocking sleeve 16 will cooperate to compress the movable spring 30. When the movable spring 30 is compressed to its limit, the locking rod 14 completely passes through the unlocking hole 17 and moves to the other side of the unlocking sleeve 16. Then, the unlocking sleeve 16 is rotated in the opposite direction, so that the unlocking sleeve 16 drives the unlocking hole 17 and the arc groove 18 to rotate in the opposite direction. Then the straight rod 13 will enter the arc groove 18. In the middle, the straight rod 13 and the locking rod 14 cooperate to limit the locking sleeve 15 to one side of the unlocking sleeve 16. Then the locking sleeve 15 no longer limits the locking rod 27. Then the rotating sleeve 5 is rotated in the forward direction. The rotating sleeve 5 will drive the multiple locking rods 27 that are slidably set on the side wall to move. Then the inner wall of the locking groove 28 presses against one end of the locking rod 27. Due to the rounded corner design at the end of the locking rod 27 and the edge of the inner wall of the locking groove 28, one end of the locking rod 27 will slide out of the locking groove 28, and the other end of the locking rod 27 will drive the return spring 29 to stretch. At the same time, because the inner wall of the rotating sleeve 5 is movably connected to the outer wall of the moving sleeve 33 through the thread, and the moving block 32 and the moving groove 31 limit the moving sleeve 33, the moving sleeve 33 will not rotate. Then the moving sleeve 33 will drive the moving block 10 along the moving block 10 through the moving block 32. The moving groove 31 slides, and the moving block 10 slides in the moving groove 7. At the same time, the distance between the moving block 10 and the linkage block 12 will decrease, making the moving block 10 closer to the linkage block 12. The linkage spring 9 is compressed, which increases the preload force applied by the linkage spring 9 to the linkage block 12 and increases the force applied by the linkage block 12 to the linkage frame 11, making the triggering more difficult. When it is necessary to adjust the triggering difficulty to be simpler, simply rotate the rotating sleeve 5 in the reverse direction. After the adjustment is appropriate, stop rotating the rotating sleeve 5, so that the locking rod 27 moves to the position corresponding to the corresponding locking groove 28. Then, the return spring 29 drives the locking rod 27 to slide into the corresponding locking groove 28. Then, rotate the unlocking sleeve 16 in the forward direction again. The unlocking sleeve 16 once again drives the unlocking hole 17 and the arc groove 18 to enter. When the lock sleeve 16 rotates forward, and the unlocking hole 17 rotates again to a position concentric with the locking rod 14, the movable spring 30 pushes the locking sleeve 15 to slide and reset. Then, the locking sleeve 15 drives the locking rod 14 to slide and reset via the straight rod 13. After the movable spring 30 has fully reset, the unlocking sleeve 16 rotates again, causing the unlocking hole 17 and the arc groove 18 to rotate to a position unrelated to the locking rod 14. Then, the straight rod 13 and the locking rod 14 work together to stably support the retractable sleeve to one side of the unlocking sleeve 16. Combined with the preload applied to the locking sleeve 15 by the movable spring 30, the locking sleeve 15 will not easily slide. Furthermore, the inner wall of the locking sleeve 15 limits the outer end of the locking rod 27 again, causing the locking rod 27 to lock the rotating sleeve 5 with the corresponding locking groove 28, preventing the rotating sleeve 5 from rotating.This ensures the stability of the adjusted structure and guarantees the stable use of the equipment.
[0037] Please see Figures 1-5 As a further implementation of the overall equipment: a movable groove 31 is provided on the side wall of the protective sleeve 8, the movable groove 31 is connected to the movable groove 7, a movable block 32 is slidably provided in the movable groove 31, a movable sleeve 33 is provided on the outside of the protective sleeve 8, the outer wall of the movable sleeve 33 is movably connected to the inner wall of the rotating sleeve 5 by threads, and the inner wall of the movable sleeve 33 is fixedly connected to multiple movable blocks 10 by the movable block 32.
[0038] The cleaning device includes an output pipe 34, an input pipe 35, a delivery pump 36, and a nozzle 37. The inlet of the delivery pump 36 is connected to the input pipe 35, the output of the delivery pump 36 is detachably connected to the output pipe 34, and the other end of the input pipe 35 is connected to an external water storage device. The nozzle 37 is detachably installed below the tank cover 19.
[0039] Multiple nozzles 37 are provided. The output end of the output pipe 34 is connected to a connecting pipe 38. The output section of the connecting pipe 38 is connected to the input end of the nozzle 37. The nozzle 37 has a spherical structure design.
[0040] More specifically, when the equipment is needed, first open the feed cover 21, then input the slurry into the storage tank 1 through the feed pipe 20, then replace the feed cover 21 on the feed pipe 20, then turn on the motor 4. The motor 4 drives the protective sleeve 8 connected to the output end to rotate, then the protective sleeve 8 drives the moving trough 7 to rotate, then the moving trough 7 drives the moving block 10, linkage block 12 and linkage frame 11 and other components set on the inner side to rotate, then the linkage frame 11 drives the stirring rod 2 to rotate through the linkage trough 6, then the stirring rod 2 drives the blade 22 to rotate, so that the blade 22 moves against the storage tank. The slurry in tank 1 rotates, and the multiple through holes 23 on the blade 22 further enhance the fluidity of the slurry, effectively preventing solidification. Then, the discharge pipe 26 is connected to the external conveying and grouting equipment, and the valve 25 is opened, allowing the slurry to flow into the external equipment for grouting through the valve 25 connected to the discharge pipe 24 and the discharge pipe 26. During the mixing process, when the blade 22 and the stirring rod 2 experience significant resistance, the stirring rod 2 cannot rotate, causing the inner wall of the linkage trough 6 to press against the end of the linkage frame 11. Due to the rounded corner design of the inner wall of the linkage trough 6 and the end of the linkage frame 11... Then, one end of the linkage frame 11 slides out of the linkage groove 6. Due to the special structural design of the other side of the linkage frame 11, the linkage frame 11 slides in the moving groove 7, and the linkage frame 11 pushes the linkage block 12 to move, causing the linkage block 12 to slide in the moving groove 7. At the same time, the linkage block 12, together with the moving block 10, squeezes the linkage spring 9, thereby causing the motor 4 to idle, effectively avoiding overload damage to the motor 4 and breakage of the stirring rod 2 and the blade 22. After the slurry inside the storage tank 1 is emptied, the valve 25 is closed, and one end of the discharge pipe 26 is disconnected from the external conveying and grouting equipment. Then, turn on the delivery pump 36, so that the delivery pump 36 draws water from the external water storage device through the input pipe 35 connected to the input end. Then, the water is delivered to the connecting pipe 38 through the output pipe 34 connected to the output end of the delivery pump 36. Then, the water is delivered to the spherical high-pressure nozzles 37 installed below the tank cover 19 through the connecting pipe 38. Finally, the water is sprayed into the storage tank through the nozzles 37, which causes the stirring rod 2 to drive the blade 22 to rotate, achieving uniform mechanized cleaning, saving time and effort. After cleaning, open the valve 25 to discharge the cleaned water from the discharge pipe 26.
[0041] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the trigger threshold according to the characteristics of the slurry, firstly, rotate the unlocking sleeve 16 in the forward direction. The unlocking sleeve 16 drives the arc groove 18 and the unlocking hole 17 to rotate. When the unlocking hole 17 rotates to a position concentric with the locking rod 14 and the straight rod 13, push the locking sleeve 15. The locking sleeve 15 will drive the locking rod 14 to slide through the straight rod 13, so that the locking rod 14 gradually enters the unlocking hole 17. The locking sleeve 15 will cooperate with the unlocking sleeve 16 to compress the movable spring 30. When the movable spring 30 is compressed to its limit, the locking rod 14 completely passes through the unlocking hole 17 and moves to the other side of the unlocking sleeve 16. Then, rotate the unlocking sleeve 16 in the reverse direction, so that the unlocking sleeve 16 drives the unlocking hole 17 and the arc groove 18 to rotate in the opposite direction. Then, the straight rod 13... The rod will enter the arc-shaped groove 18, and then the straight rod 13 and the locking rod 14 will cooperate to limit the locking sleeve 15 to the side of the unlocking sleeve 16. Then the locking sleeve 15 will no longer limit the locking rod 27. Then the rotating sleeve 5 will rotate in the forward direction, and the rotating sleeve 5 will drive the multiple locking rods 27 that are slidably set on the side wall to move. Then the inner wall of the locking groove 28 will press one end of the locking rod 27. Due to the rounded corner design at the end of the locking rod 27 and the edge of the inner wall of the locking groove 28, one end of the locking rod 27 will slide out of the locking groove 28, and the other end of the locking rod 27 will drive the return spring 29 to stretch. At the same time, because the inner wall of the rotating sleeve 5 is movably connected to the outer wall of the moving sleeve 33 through the thread, and the moving block 32 and the moving groove 31 limit the moving sleeve 33, the moving sleeve 33 will not rotate. Then the moving sleeve 33 will be driven by the moving block 32. The movable block 10 slides along the movable groove 31 and slides within the movable groove 7. Simultaneously, the distance between the movable block 10 and the linkage block 12 decreases, bringing the movable block 10 closer to the linkage block 12. The linkage spring 9 is compressed, increasing the preload force exerted by the linkage spring 9 on the linkage block 12 and increasing the force exerted by the linkage block 12 on the linkage frame 11, thus increasing the triggering difficulty. To simplify the triggering process, simply rotate the rotating sleeve 5 in the opposite direction. After adjustment, stop rotating the rotating sleeve 5, causing the locking rod 27 to move to the position corresponding to the locking groove 28. Then, the return spring 29 drives the locking rod 27 to slide into the corresponding locking groove 28. Finally, rotate the unlocking sleeve 16 in the forward direction again, causing the unlocking hole to... When the unlocking hole 17 and the arc-shaped groove 18 rotate in the forward direction, and the unlocking hole 17 rotates again to a position concentric with the locking rod 14, the movable spring 30 pushes the locking sleeve 15 to slide and reset. Then, the locking sleeve 15 drives the locking rod 14 to slide and reset via the straight rod 13. After the movable spring 30 has fully reset, the unlocking sleeve 16 rotates again, causing the unlocking sleeve 16 to drive the unlocking hole 17 and the arc-shaped groove 18 to a position not related to the locking rod 14. Then, the straight rod 13 and the locking rod 14 cooperate to stably support the retracting sleeve to one side of the unlocking sleeve 16. With the preload applied to the locking sleeve 15 by the movable spring 30, the locking sleeve 15 will not easily slide, and the inner wall of the locking sleeve 15 limits the outer end of the locking rod 27 again, so that the locking rod 27 locks the rotating sleeve 5 with the corresponding locking groove 28.This prevents the rotating sleeve 5 from rotating, thus ensuring the stability of the adjusted structure and guaranteeing the stable operation of the equipment.
[0042] When the equipment is needed, first open the feed cover 21, then feed the slurry into the storage tank 1 through the feed pipe 20. Then, replace the feed cover 21 on the feed pipe 20, and turn on the motor 4. The motor 4 drives the protective sleeve 8 connected to the output end to rotate, and then the protective sleeve 8 drives the moving trough 7 to rotate. Then, the moving trough 7 drives the moving block 10, the linkage block 12, and the linkage frame 11, etc., set on the inner side to rotate. Then, the linkage frame 11 drives the stirring rod 2 to rotate through the linkage trough 6, and then the stirring rod 2 drives the blade 22 to rotate, so that the blade 22 moves against the contents of the storage tank 1. The slurry rotates, and the multiple through holes 23 on the blade 22 further enhance the slurry's fluidity, effectively preventing solidification. Then, the discharge pipe 26 is connected to external conveying and grouting equipment, and valve 25 is opened, allowing the slurry to flow into the external equipment for grouting through valve 25 connected to the discharge pipe 24 and the discharge pipe 26. During the mixing process, when the blade 22 and the stirring rod 2 experience significant resistance, the stirring rod 2 cannot rotate, causing the inner wall of the linkage trough 6 to press against the end of the linkage frame 11. Due to the rounded corner design of the inner wall of the linkage trough 6 and the end of the linkage frame 11, ... One end of the rear linkage frame 11 slides out of the linkage groove 6. Due to the special structural design of the other side of the linkage frame 11, the linkage frame 11 slides in the moving groove 7, and the linkage frame 11 pushes the linkage block 12 to move, causing the linkage block 12 to slide in the moving groove 7. At the same time, the linkage block 12, together with the moving block 10, squeezes the linkage spring 9, thereby causing the motor 4 to idle, effectively avoiding overload damage to the motor 4 and breakage of the stirring rod 2 and the blade 22. After the slurry inside the storage tank 1 is emptied, the valve 25 is closed, and one end of the discharge pipe 26 is disconnected from the external conveying and grouting equipment. Turn on the delivery pump 36 so that it draws water from the external water storage device through the input pipe 35 connected to the input end. Then, the water is delivered to the connecting pipe 38 through the output pipe 34 connected to the output end of the delivery pump 36. The water is then delivered to the spherical high-pressure nozzles 37 installed below the tank cover 19 through the connecting pipe 38. Finally, the water is sprayed into the storage tank through the nozzles 37, causing the stirring rod 2 to drive the blades 22 to rotate, achieving uniform mechanized cleaning, saving time and effort. After cleaning, open the valve 25 to discharge the cleaned water from the discharge pipe 26.
