Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a dust removal and protection device for water conservancy tunnel construction. Background Technology

[0002] Dust control and protection devices are commonly used in water conservancy tunnel construction, mainly categorized into wet spraying, dry filtration, and ventilation systems. Common structures include fixed pipelines, mobile pole-mounted spray frames, and dust collection trolleys. Mobile pole-mounted spray frames are typically equipped with telescopic poles, atomizing nozzles, water pumps, and mobile bases. Some mobile pole-mounted spray frames integrate water storage chambers, relying on water mist to adsorb dust. They are adaptable to multiple processes such as tunneling, slag removal, and blasting, thereby reducing dust concentration and ensuring a safe working environment.

[0003] In existing dust control and protection equipment, the mobile pole-mounted spray frame only has a water storage chamber and lacks a rainwater collection mechanism, so it cannot collect rainwater. The tunnel interior mostly relies on external water supply pipelines or water trucks for water supply. The cost of water supply and transportation is high in remote or long tunnels, and the dust control operation may even be interrupted due to water outages. As a result, natural rainwater resources cannot be utilized, and the water resource utilization rate is low. Therefore, it not only increases the cost of water conservancy tunnel construction, but also wastes water resources. Summary of the Invention

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 - Appendix Figure 13This invention provides a dust control and protection device for hydraulic tunnel construction, comprising a mobile vehicle body 1, a telescopic rod 2 fixedly connected to the top of one side of the mobile vehicle body 1, a nozzle 3 disposed at the top of the telescopic rod 2, a movement restriction mechanism 9 disposed at the top of the mobile vehicle body 1, a moving seat 4 disposed at the top of the movement restriction mechanism 9, the movement restriction mechanism 9 being able to restrict the movement trajectory of the moving seat 4 and restrict the movement of the moving seat 4, a water storage tank 5 disposed inside the moving seat 4 for collecting rainwater, a rainwater collection mechanism 6 disposed outside the water storage tank 5 for expanding the rainwater collection area, and a filter disposed at the top of the water storage tank 5. Mechanism 7, the filter mechanism 7 is used to filter rainwater. The filter mechanism 7 is equipped with a water passage mechanism 8. A water pump 10 is fixedly connected to one end of the top of the mobile vehicle body 1. The water passage mechanism 8 is used to connect the water pump 10 and the filter mechanism 7. A water pump pipe 11 is fixedly connected to the input end of the water pump 10. A water outlet pipe 12 is fixedly connected to the output end of the water pump 10. The end of the water outlet pipe 12 away from the water pump 10 can be connected to the pipe inside the telescopic rod 2. The top of the pipe inside the telescopic rod 2 is connected to the input end of the nozzle 3. So that when the water pump 10 is started, the liquid in the water storage tank 5 can be drawn into the interior of the nozzle 3 and sprayed out by the nozzle 3 to suppress dust.

[0034] The rainwater harvesting mechanism 6 includes a mounting ring 601 and a sliding ring 604. Multiple support rods 602 are fixedly connected to the outside of the mounting ring 601, providing the mounting position. A rotating roller 603 is rotatably connected to the top of each support rod 602. The sliding ring 604 is slidably connected to the outside of the water storage tank 5, providing the mounting position and allowing the rainwater harvesting mechanism 6 to be mounted on the water storage tank 5, maintaining its stability. An unfolding / retracting frame 605 is rotatably connected to the top of the sliding ring 604. Limited by the support rods 602 and the rotating roller 603, the unfolding / retracting frame 605 unfolds when it moves upward and collapses when it moves downward. The shrinking and expanding frame 605 has a groove 606 inside, which provides space for the rotating roller 603 to slide inside the shrinking frame 605. The rotating roller 603 is located inside the groove 606. Multiple mounting cylinders 607 are fixedly connected to the outside of the mounting ring 601. The mounting cylinders 607 provide the mounting position. A lifting spring 608 is installed inside the mounting cylinder 607. A movable plug 609 is slidably connected inside the mounting cylinder 607. The movable plug 609 has a limiting function. A movable rod 610 is fixedly connected to the top of the movable plug 609. The movable rod 610 has a connecting function. The lifting spring 608 can use its own reaction force to push the movable plug 609 and the movable rod 610 upward. The sliding ring 604 can be moved upwards. The top of the movable rod 610 is fixedly connected to the outside of the sliding ring 604. The movable plug 609 has multiple liquid passage holes 611 inside, which provide space for liquid to pass through. The flow rate of the liquid through the liquid passage holes 611 is reduced, which can reduce the moving speed of the movable plug 609. The mounting ring 601 is fixedly connected to the outside of the mounting rod 612, which provides the installation position. The top of the mounting rod 612 is fixedly connected to the top of the mounting rod 612. The fixed rod 613 is rotatably connected to the outside of the fixed rod 613. The bottom end of the rotatable hook 614 is provided with a torsion spring 615. The torsion spring 615 can drive the rotatable hook 614 to rotate in the opposite direction. The water storage tank 5 is fixedly connected to the outside of the mounting ring 601. The rainwater collection mechanism 6 is mounted on the fixing ring 618, allowing it to be installed on the water storage tank 5. The sliding ring 604 maintains the stability of the rainwater collection mechanism 6. The inner side of the mounting ring 601 is fitted over the outer side of the fixing ring 618. Multiple locking pins 619 are fixedly connected to the outer side of the sliding ring 604. These pins 619 engage with the rotating hook 614, enabling the retraction of the unfolding / retracting frame 605. A rain cover 620 is fixedly connected between the multiple unfolding / retracting frames 605. The unfolding of the rain cover 620 increases the rainwater collection area, while its retraction saves space. One end of the lifting spring 608 is fixedly connected to the inside of the mounting cylinder 607, and the other end is fixedly connected to the top of the movable plug 609.One end of the torsion spring 615 is fixedly connected to the inside of the bottom end of the rotating hook 614, and the other end of the torsion spring 615 is fixedly connected to the outside of the fixed rod 613. A support plate 616 is fixedly connected to one side of the top of the upright rod 612, and a horizontal plate 617 is fixedly connected to one side of the bottom end of the rotating hook 614.

[0035] When collecting rainwater, rotating the hook 614 away from the horizontal plate 617 releases the locking pin 619. At this time, the reaction force of the lifting spring 608 pushes the movable plug 609 upward. Because the size of the liquid passage hole 611 is limited, the speed at which the liquid inside the mounting cylinder 607 passes through the liquid passage hole 611 is restricted when the movable plug 609 moves upward. Therefore, the upward speed of the movable plug 609 is limited, thus pushing the movable rod 610 upward slowly. This, in turn, slowly moves the sliding ring 604 upward. The unfolding and retracting frame 605 is restricted by the rotating roller 603, thus causing the unfolding... The retractable frame 605 unfolds in all directions, allowing the rain cover 620 to be unfolded, thus facilitating rainwater collection. When the rainwater collection mechanism 6 is retracted in sunny weather, the locking pin 619 is pulled downwards, which in turn moves the sliding ring 604 downwards. This causes one end of the retractable frame 605 to move downwards, and under the constraint of the rotating roller 603, the retractable frame 605 can reverse and move downwards, allowing the rain cover 620 to retract. This also causes the movable rod 610 and movable plug 609 to move downwards, compressing the lifting spring 608. When the locking pin 619 contacts the top inclined surface of the rotating hook 614, it can... Under the pressure, the rotating hook 614 rotates away from the horizontal plate 617, compressing the torsion spring 615. When the locking pin 619 moves below the top of the rotating hook 614, the reaction force of the torsion spring 615 causes the rotating hook 614 to rotate in the opposite direction, and causes the horizontal plate 617 to rotate towards the support plate 616. When the horizontal plate 617 abuts against the top of the support plate 616, the rotating hook 614 remains upright, and the locking pin 619 engages at the top and bottom of the rotating hook 614, thus preventing the lifting spring 608 from pushing the sliding ring 604 upward using its own reaction force. The rain cover 620 can be retracted by moving the rainwater collection mechanism 6. When the rainwater collection mechanism 6 is removed from the water storage tank 5, the sliding ring 604 can be lifted upwards, causing the sliding ring 604 to slide out of the water storage tank 5 and drive the mounting ring 601 to slide upwards, causing the mounting ring 601 to slide out of the fixing ring 618. After the mounting ring 601 slides out of the water storage tank 5, the rainwater collection mechanism 6 can be disassembled. To install the rainwater collection mechanism 6, the mounting ring 601 and the sliding ring 604 are slid down along the outside of the water storage tank 5, and the mounting ring 601 is placed on the outside of the fixing ring 618, thus completing the installation of the rainwater collection mechanism 6.

[0036] The filtration mechanism 7 includes a mounting ring 701, which, when placed on top of the water storage tank 5, facilitates the installation of the entire filtration mechanism 7 on top of the tank 5. A funnel 702 is fixedly connected to the inner side of the mounting ring 701, allowing for convenient rainwater collection. A filter frame 703 is fixedly connected to the bottom of the funnel 702, filtering the collected rainwater. A mounting box 704 is fixedly connected to the bottom of the filter frame 703, providing an installation position. An impeller 705 is rotatably connected inside the mounting box 704, rotating under the influence of liquid flow. A transmission rod 706 is fixedly connected to the top of the impeller 705, driving the transmission rod 706 to rotate. Multiple mounting brackets 707 are fixedly connected to the outside of the transmission rod 706, providing installation positions. Multiple movable limits are slidably connected inside the mounting brackets 707. The movable limit rod 708 is fitted with a retaining spring 709. A cleaning plate 710 is fixedly connected between multiple movable limit rods 708. The retaining spring 709 uses its own reaction force to press the cleaning plate 710 against the inner wall of the filter frame 703, thereby improving the impurity cleaning effect. A limiting plate 711 is fixedly connected to the end of the movable limit rod 708 away from the cleaning plate 710. The limiting plate 711 prevents the movable limit rod 708 from sliding off the mounting bracket 707. Multiple positioning posts 713 are fixedly connected to the top of the barrel 5. Multiple positioning holes 712 are opened inside the mounting ring 701. After the positioning holes 712 slide into the outside of the positioning posts 713, the mounting ring 701 can be easily positioned. The positioning posts 713 are inserted into the inside of the positioning holes 712. One end of the clamping spring 709 is fixedly connected to the side of the mounting bracket 707 away from the transmission rod 706, and the other end of the clamping spring 709 is fixedly connected to the end of the cleaning plate 710 near the transmission rod 706.

[0037] When using nozzle 3 for dust suppression, water pump 10 is started. Water is drawn from the input end of pump 10 via suction pipe 11. The water flows through suction pipe 714 into the mounting box 704, then through the mounting box 704 into the water-passing mechanism 8, and finally through outlet pipe 12 into the nozzle 3 via a pipe connected to the bottom of nozzle 3. Water mist is then sprayed out from nozzle 3. Once the water enters the mounting box 704, it drives impeller 705 to rotate. The rotation of impeller 705 drives transmission rod 706 to rotate. The rotation of transmission rod 706 drives mounting bracket 707, movable limit rod 708, and cleaning plate 710 to rotate, thus effectively removing excess water. Impurities filtered from rainwater are automatically scraped off the inner wall of the filter frame 703. Before collecting rainwater again, the filter mechanism 7 is lifted upwards, which causes the mounting ring 701 to move upwards, allowing the positioning hole 712 to move out of the positioning post 713. Once the liquid extraction pipe 714 moves out of the water storage tank 5, the filter mechanism 7 can be disassembled. The disassembled funnel 702 is flipped over to pour out the impurities inside the filter frame 703. When installing the filter mechanism 7, the mounting ring 701 is aligned with the top of the water storage tank 5 and lowered, with the positioning hole 712 aligned with the positioning post 713. When the mounting ring 701 contacts the top of the water storage tank 5, the installation of the filter mechanism 7 is complete.

[0038] The water-passing mechanism 8 includes a connecting curved pipe 801 and a connecting pipe 802. The connecting curved pipe 801 guides the water flow. One end of the connecting pipe 802 is fixedly connected to one end of the mounting box 704. The other end of the connecting pipe 802 is slidably connected to a sliding connecting sleeve 805. After the sliding connecting sleeve 805 slides into the top of the connecting curved pipe 801, it can connect the connecting pipe 802 to the connecting curved pipe 801. A blocking ring 803 is fixedly connected to the outside of the connecting pipe 802, providing an installation position. A compression spring 804 is fitted around the outside of the 02, which provides a downward reaction force to the sliding connecting sleeve 805, causing it to press against the top of the connecting curved tube 801. This improves the seal between the connecting curved tube 801 and the sliding connecting sleeve 805. The bottom end of the sliding connecting sleeve 805 is fitted inside the connecting curved tube 801. A fixing ring 806 is fixedly connected inside the end of the connecting curved tube 801 away from the sliding connecting sleeve 805. The fixing ring 806 provides the installation position and fixes the connection. A return spring 807 is fixedly connected to one end of the ring 806, and a sliding frame 808 is fixedly connected to the other end of the return spring 807. A connecting rod 809 is fixedly connected to the middle of the sliding frame 808, and a stopper 810 is fixedly connected to the end of the connecting rod 809 away from the sliding frame 808. The return spring 807 can provide a reaction force to the sliding frame 808, thereby driving the connecting rod 809 and the stopper 810 to move towards the water pipe 11, and causing the stopper 810 to block inside the fixed ring 806, thus... The stopper 810 is slidably connected to the middle of the stopper 806, and the end of the water pipe 11 away from the water pump 10 is fixedly connected to the retaining ring 811. The retaining ring 811 can block the connecting curved pipe 801. One end of the compression spring 804 is fixedly connected to the bottom of the blocking ring 803, and the other end of the compression spring 804 is fixedly connected to the top of the sliding connecting sleeve 805. The bottom of the connecting pipe 802 is fixedly connected to the sealing ring 812, and the sealing ring 812 is slidably connected inside the sliding connecting sleeve 805.

[0039] When the filter mechanism 7 is disassembled, it moves the connecting pipe 802 upward, which in turn moves the blocking ring 803 upward. When the blocking ring 803 moves upward, it moves the clamping spring 804 and the sliding connecting sleeve 805 upward, allowing the sliding connecting sleeve 805 to leave the interior of the connecting curved pipe 801. When the filter mechanism 7 is installed, it moves the connecting pipe 802 downward, causing the blocking ring 803, clamping spring 804, and sliding connecting sleeve 805 downward. When the sliding connecting sleeve 805 contacts the top of the connecting curved pipe 801, it is held in place. As the filter mechanism 7 continues to move downward... As the connecting pipe 802 continues to move downwards, it drives the blocking ring 803 to move downwards as well. The blocking ring 803 then compresses the compression spring 804, which in turn exerts a downward force on the sliding connecting sleeve 805, tightly pressing it against the top of the connecting curved pipe 801. This improves the sealing effect. When the moving seat 4 and the water storage tank 5 are placed on the moving vehicle 1, the moving limiting mechanism 9 ensures that the connecting curved pipe 801 is accurately inserted into the water suction pipe 11. This allows the water suction pipe 11 to push the sliding frame 808 towards the liquid suction pipe 714, which in turn drives the connecting rod 809 and the stopper 81. The stopper 810 moves towards the suction pipe 714. After the stopper 810 moves out of the interior of the fixing ring 806, water can flow through the fixing ring 806 and the connecting curved pipe 801 into the interior of the suction pipe 11. The water is then pumped into the nozzle 3 by the water pump 10, and water mist is sprayed out through the nozzle 3. When the sliding frame 808 squeezes the return spring 807, the sliding frame 808 is pressed tightly against the suction pipe 11 by the reaction force of the sliding frame 808, thereby improving the sealing effect. When the connecting curved pipe 801 abuts against the retaining ring 811, it can block the connecting curved pipe 801, preventing it from moving further towards the water pump 10. When the moving seat 4 and the water storage tank 5 are moved from the... When the water tank 5 is removed from the mobile vehicle body 1, it can drive the connecting curved pipe 801 to move away from the water pump 10. After the water pipe 11 leaves the inside of the connecting curved pipe 801, it can push the sliding frame 808 towards the water pump 10 under the reaction force of the return spring 807. The sliding frame 808 can also drive the connecting rod 809 and the plug 810 towards the water pump 10, so that the plug 810 can move into the inside of the fixing ring 806, thereby blocking the connecting curved pipe 801. At this time, after the inside of the water tank 5 is filled with liquid, the liquid will not flow out from the inside of the connecting curved pipe 801 after the filter mechanism 7 is removed from the top of the water tank 5.

[0040] The movement restriction mechanism 9 includes two slide rails 901, which provide sliding tracks for the wheels at the bottom of the movable seat 4, thereby restricting the movement trajectory of the movable seat 4. The bottoms of both slide rails 901 are fixedly connected to the interior of the movable vehicle body 1. Two rows of pulleys at the bottom of the movable seat 4 are respectively arranged inside the two slide rails 901. A stop block 902 is slidably connected inside the slide rail 901. The bottom of the stop block 902 is provided with anti-slip texture. The stop block 902 abuts against the wheels of the movable seat 4 to prevent the movable seat 4 from moving. A fixing cylinder 903 is fixedly connected to the top of the stop block 902, providing an installation position. A pressure spring 904 is provided inside the fixing cylinder 903. A limit slide plate 905 is slidably connected inside the fixing cylinder 903, which has a limiting function. A movable rod 906 is fixedly connected to the middle of 905. The movable rod 906 has the function of installation and connection. A pressing block 909 is fixedly fixed to the bottom of the movable rod 906. After the pressing block 909 presses against the inside of the slide rail 901, the pressure of the pressure spring 904 can increase the friction between the pressing block 909 and the slide rail 901, thereby preventing the pressing block 902 from moving. A limiting groove 908 is opened inside the pressing block 902. The limiting groove 908 provides sliding space for the pressing block 909. The pressing block 909 is slidably connected inside the limiting groove 908. One end of the pressure spring 904 is fixedly connected to the inside of the fixed cylinder 903. The other end of the pressure spring 904 is fixedly connected to the top of the limiting slide 905. A round handle 907 is fixedly connected to the top of the movable rod 906. The movable rod 906 is slidably connected to the middle of the fixed cylinder 903.

[0041] After placing the water tank 5 on the movable seat 4, align the wheels at the bottom of the movable seat 4 with the slide rail 901 and push it in. Since the wheels at the bottom of the movable seat 4 are in contact with the inside of the slide rail 901, the movable seat 4 can move linearly. When the end of the connecting curved pipe 801 away from the suction pipe 714 abuts against the retaining ring 811, stop pushing the movable seat 4 and the water tank 5. At this point, slide the abutment block 902 into the inside of the slide rail 901, so that the abutment block 902 abuts against the wheels of the movable seat 4. Release the round handle 907, and the limit can be pushed under the reaction force of the pressure spring 904. The sliding plate 905 moves downward, which in turn drives the moving rod 906 to move downward, and drives the abutment block 909 to move downward. When the moving rod 906 contacts the slide rail 901, the reaction force of the pressure spring 904 acts on the abutment block 909, which makes the abutment block 909 press tightly against the slide rail 901, thereby increasing the friction and making it more difficult for the abutment block 902 to move away from the telescopic rod 2. This can hold the wheel at the bottom of the moving seat 4 in place, so that the moving seat 4 will not move. At this time, the water storage tank 5 can be installed on the moving vehicle body 1.

[0042] Working principle: When collecting rainwater, rotating the hook 614 away from the horizontal plate 617 releases the locking pin 619. At this time, the reaction force of the lifting spring 608 pushes the movable plug 609 upward. Because the size of the liquid passage hole 611 is limited, the speed at which the liquid inside the mounting cylinder 607 passes through the liquid passage hole 611 is restricted when the movable plug 609 moves upward. Therefore, the upward speed of the movable plug 609 is limited, thus pushing the movable rod 610 upward slowly. This, in turn, slowly moves the sliding ring 604 upward. The unfolding and retracting frame 605 is restricted by the rotating roller 603. This causes the retractable frame 605 to expand outwards, thereby unfolding the tarpaulin surface 620 for easy rainwater collection. When the rainwater collection mechanism 6 is retracted in sunny weather, the locking pin 619 is pulled downwards, which in turn moves the sliding ring 604 downwards. This causes one end of the retractable frame 605 to move downwards, and under the constraint of the rotating roller 603, the retractable frame 605 can reverse and move downwards, thereby retracting the tarpaulin surface 620. This also causes the movable rod 610 and the movable plug 609 to move downwards, compressing the lifting spring 608. When the locking pin 619 contacts the top inclined surface of the rotating hook 614, Under the pressure of compression, the rotating hook 614 can rotate away from the horizontal plate 617 and compress the torsion spring 615. When the locking pin 619 moves to below the top of the rotating hook 614, it can drive the rotating hook 614 to rotate in the opposite direction under the reaction force of the torsion spring 615, and drive the horizontal plate 617 to rotate towards the support plate 616. After the horizontal plate 617 abuts against the top of the support plate 616, the rotating hook 614 can remain upright, and the locking pin 619 can be engaged at the top and bottom of the rotating hook 614, thereby preventing the lifting spring 608 from pushing the sliding ring 604 towards the top using its own reaction force. The rain cover 620 can be retracted by moving it upwards. If the rainwater collection mechanism 6 is removed from the water storage tank 5, the sliding ring 604 can be lifted upwards, causing the sliding ring 604 to slide out of the water storage tank 5 and drive the mounting ring 601 to slide upwards, causing the mounting ring 601 to slide out of the fixing ring 618. After the mounting ring 601 slides out of the water storage tank 5, the rainwater collection mechanism 6 can be disassembled. To install the rainwater collection mechanism 6, the mounting ring 601 and the sliding ring 604 are slid down along the outside of the water storage tank 5, and the mounting ring 601 is put on the outside of the fixing ring 618, thus completing the installation of the rainwater collection mechanism 6.

[0043] When using nozzle 3 for dust suppression, water pump 10 is started. Water is drawn from the input end of pump 10 via suction pipe 11. The water flows through suction pipe 714 into the mounting box 704, then through the mounting box 704 into the water-passing mechanism 8, and finally through outlet pipe 12 into the nozzle 3 via a pipe connected to the bottom of nozzle 3. Water mist is then sprayed out from nozzle 3. Once the water enters the mounting box 704, it drives impeller 705 to rotate. The rotation of impeller 705 drives transmission rod 706 to rotate. The rotation of transmission rod 706 drives mounting bracket 707, movable limit rod 708, and cleaning plate 710 to rotate, thus effectively removing excess water. Impurities filtered from rainwater are automatically scraped off the inner wall of the filter frame 703. Before collecting rainwater again, the filter mechanism 7 is lifted upwards, which causes the mounting ring 701 to move upwards, allowing the positioning hole 712 to move out of the positioning post 713. After the liquid extraction pipe 714 moves out of the water storage tank 5, the filter mechanism 7 can be disassembled. The disassembled funnel 702 is flipped over to pour out the impurities inside the filter frame 703. When installing the filter mechanism 7, the mounting ring 701 is aligned with the top of the water storage tank 5 and lowered, with the positioning hole 712 aligned with the positioning post 713. When the mounting ring 701 contacts the top of the water storage tank 5, the installation of the filter mechanism 7 is completed.

[0044] When the filter mechanism 7 is disassembled, it moves the connecting pipe 802 upward, which in turn moves the blocking ring 803 upward. When the blocking ring 803 moves upward, it moves the clamping spring 804 and the sliding connecting sleeve 805 upward, allowing the sliding connecting sleeve 805 to leave the interior of the connecting curved pipe 801. When the filter mechanism 7 is installed, it moves the connecting pipe 802 downward, causing the blocking ring 803, clamping spring 804, and sliding connecting sleeve 805 downward. When the sliding connecting sleeve 805 contacts the top of the connecting curved pipe 801, it is held in place. As the filter mechanism 7 continues to move downward... As the connecting pipe 802 continues to move downwards, it drives the blocking ring 803 to move downwards as well. The blocking ring 803 then compresses the compression spring 804, which in turn exerts a downward force on the sliding connecting sleeve 805, tightly pressing it against the top of the connecting curved pipe 801. This improves the sealing effect. When the moving seat 4 and the water storage tank 5 are placed on the moving vehicle 1, the moving limiting mechanism 9 ensures that the connecting curved pipe 801 is accurately inserted into the water suction pipe 11. This allows the water suction pipe 11 to push the sliding frame 808 towards the liquid suction pipe 714, which in turn drives the connecting rod 809 and the stopper 81. The stopper 810 moves towards the suction pipe 714. After the stopper 810 moves out of the interior of the fixing ring 806, water can flow through the fixing ring 806 and the connecting curved pipe 801 into the interior of the suction pipe 11. The water is then pumped into the nozzle 3 by the water pump 10, and water mist is sprayed out through the nozzle 3. When the sliding frame 808 squeezes the return spring 807, the sliding frame 808 is pressed tightly against the suction pipe 11 by the reaction force of the sliding frame 808, thereby improving the sealing effect. When the connecting curved pipe 801 abuts against the retaining ring 811, it can block the connecting curved pipe 801, preventing it from moving further towards the water pump 10. When the moving seat 4 and the water storage tank 5 are moved from the... When the water tank 5 is removed from the mobile vehicle body 1, it can drive the connecting curved pipe 801 to move away from the water pump 10. After the water pipe 11 leaves the inside of the connecting curved pipe 801, it can push the sliding frame 808 to move towards the water pump 10 under the reaction force of the return spring 807. It can also drive the connecting rod 809 and the plug 810 to move towards the water pump 10 through the sliding frame 808. This allows the plug 810 to move into the inside of the fixing ring 806, thereby blocking the connecting curved pipe 801. At this time, after the inside of the water tank 5 is filled with liquid, the liquid will not flow out from the inside of the connecting curved pipe 801 after the filter mechanism 7 is removed from the top of the water tank 5.

[0045] After placing the water tank 5 on the movable seat 4, align the wheels at the bottom of the movable seat 4 with the slide rail 901 and push it in. Since the wheels at the bottom of the movable seat 4 are in contact with the inside of the slide rail 901, the movable seat 4 can move linearly. When the end of the connecting curved pipe 801 away from the suction pipe 714 abuts against the retaining ring 811, stop pushing the movable seat 4 and the water tank 5. At this point, slide the abutment block 902 into the inside of the slide rail 901, so that the abutment block 902 abuts against the wheels of the movable seat 4. Release the round handle 907, and the limit can be pushed under the reaction force of the pressure spring 904. The sliding plate 905 moves downward, which in turn drives the moving rod 906 to move downward, and drives the abutment block 909 to move downward. When the moving rod 906 contacts the slide rail 901, the reaction force of the pressure spring 904 acts on the abutment block 909, which makes the abutment block 909 press tightly against the slide rail 901, thereby increasing the friction and making it more difficult for the abutment block 902 to move away from the telescopic rod 2. This can hold the wheel at the bottom of the moving seat 4 in place, so that the moving seat 4 will not move. At this time, the water storage tank 5 can be installed on the moving vehicle body 1.
