[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a high-pressure water jet cleaning device for coal mining, such as Figures 1 to 4 As shown, it includes two rails 1 arranged in parallel, and the bottom surfaces of the two rails 1 are fixedly connected to a bottom plate 2, a water tank 3 is arranged on the top of the rail 1, and a wheel 4 corresponding to the rail 1 is fixed to the bottom of the water tank 3, and the water tank 3 moves back and forth on the top of the rail 1 through the wheel 4, and a cover frame 5 is placed on the top opening of the water tank 3, and a movable frame 6 is placed on the top surface of the cover frame 5, a boosting chamber 7 is arranged on the inner side of the movable frame 6, and a drain pipe 8 is arranged on the front side of the boosting chamber 7, a water inlet pipe 9 is arranged inside the water tank 3, and the bottom end of the water inlet pipe 9 is connected to a water pump, and the water pump is placed inside the water tank 3, and the bottom of the boosting chamber 7 is connected to the top of the water inlet pipe 9 through a water passing structure, and the water pump transmits the water inside the water tank 3 to the inside of the boosting chamber 7 through the water inlet pipe 9 and the water passing structure, and the boosting chamber 7 uses the drain pipe 8 to spray water out. The bracket to be flushed is placed on the ground, the water tank 3 is connected to a water inlet faucet, the faucet is turned on, and water directly flows into the water tank 3. The water pump draws the water inside the water tank 3 into the water inlet pipe 9. The water inside the water inlet pipe 9 is transmitted to the inside of the boosting chamber 7 through the water passing structure. After the boosting chamber 7 pressurizes the incoming water, the pressurized water is sprayed out through the drain pipe 8. At this time, the water tank 3 moves back and forth on the top of the track 1 through the wheels 4, and the water sprayed from the drain pipe 8 moves back and forth to flush the bracket.

[0028] exist Figure 1 and Figure 2In the figure, protrusions are fixed at the four corners of the top opening of the water tank 3, and a plurality of vertical rods 10 are fixed to the inner bottom surface of the cover frame 5. The plurality of vertical rods 10 correspond to the plurality of protrusions one by one, and the bottom ends of the vertical rods 10 correspond to the centers of the protrusions. A floating plate 11 is fixed to the bottom ends of the vertical rods 10, and the floating plate 11 is inside the water tank 3. A spring 12 is sleeved on the surface of the vertical rod 10, and the top end of the spring 12 is connected to the bottom surface of the protrusion, and the bottom end of the spring 12 is connected to the top surface of the floating plate 11. When the water tank 3 moves back and forth on the top of the track 1 using the wheels 4, the water tank 3 that moves back and forth drives the pressurizing chamber 7 and the drain pipe 8 to move back and forth synchronously through the cover frame 5, and the weight of the cover frame 5 is applied to the top of the floating plate 11 through multiple vertical rods 10. When the floating plate 11 moves downward inside the water tank 3, it cooperates with the protrusion to pull the spring 12 on the surface of the vertical rod 10, and the buoyancy of the floating plate 11 itself inside the water tank 3 and the elastic force of the spring 12 cooperate to support the cover frame 5. When the water inside the water tank 3 gradually decreases until the liquid level of the water inside the water tank 3 corresponds to the bottom surface of the floating plate 11, the water inside the water tank 3 continues to spray out through the drain pipe 8, and the water level inside the water tank 3 gradually decreases. The weight of the cover frame 5 makes the floating plate 11 at the bottom end of the vertical rod 10 move downward synchronously with the water level, and the horizontal plane where the center line of the drain pipe 8 is located gradually moves downward. The water spraying height of the drain pipe 8 is regulated by controlling the liquid level of the water inside the water tank 3. At this time, the water sprayed from the drain pipe 8 can flush the different heights of the bracket.

[0029] When an external component impacts the top of the cover frame 5 and the cover frame 5 moves downward, the cover frame 5 pulls the spring 12 through the float plate 11 at the bottom of the vertical rod 10, and the floating plate 11 moves downward inside the water tank 3. The buoyancy of the water inside the water tank 3 on the float plate 11 and the elastic force of the spring 12 cooperate to absorb the power of the cover frame 5 moving downward, thereby preventing the bottom surface of the cover frame 5 from directly impacting the top surface of the water tank 3 and preventing the water tank 3 and the cover frame 5 from being damaged by impact.

[0030] exist Figures 1 to 4 In the embodiment, the cover frame 5 has side frames 13 fixed on both sides of the top surface, and the two sides of the mobile frame 6 are placed at the top openings of the two side frames 13. A rotating rod 14 is arranged inside the side frame 13, and the two ends of the rotating rod 14 respectively penetrate the centers of the two end surfaces of the side frame 13. Gears 15 are fixed on both ends of the rotating rod 14, and the gears 15 are externally connected to the output end of the motor. Belts 16 corresponding to the gears 15 are arranged on both ends of the side frame 13, and two adjacent gears 15 are matched by the transmission of the belts 16. Start the motor, and when the motor is working, the motor output end drives the gears 15 to rotate, and when the rotating gears 15 drive the adjacent gears 15 to rotate synchronously by the belts 16, the gears 15 drive the rotating rods 14 to rotate inside the side frame 13, and at this time, the two rotating rods 14 rotate synchronously under the synchronous drive of the two adjacent gears 15.

[0031] The side frame 13 is provided with a slider 17 inside, and the rotating rod 14 corresponds to the spiral that penetrates the center of the slider 17. The rotating rotating rod 14 enables the slider 17 to move inside the side frame 13. The top of the slider 17 is fixedly connected to the side bottom surface of the mobile frame 6 through the opening at the top of the side frame 13. The slider 17 drives the mobile frame 6 to move synchronously during the movement. When the two rotating rods 14 rotate synchronously, due to the limitation of the slider 17 by the side frame 13 itself, the rotating rotating rod 14 enables the slider 17 to move back and forth inside the side frame 13. The two synchronously rotating rotating rods 14 further enable the sliders 17 inside the two side frames 13 to move synchronously, and the movement of the slider 17 drives the mobile frame 6 to move on the top of the cover frame 5. The spiral effect of the rotating rod 14 and the slider 17 is used to limit the mobile frame 6, so as to prevent the counter-impact force of the water sprayed by the drain pipe 8 from causing the mobile frame 6 to move on the top of the cover frame 5. The movable frame 6 is limited by the spiral effect of the rotating rod 14 and the slider 17, and the distance between the water outlet end of the drain pipe 8 and the bracket can be adjusted according to the situation to prevent the water flow from spreading everywhere, thereby avoiding the distance between the drain pipe 8 and the bracket being too close.

[0032] exist Figure 4 and Figure 5 In the embodiment, the water-passing structure includes a middle frame 18, which is located at the center of the top surface of the cover frame 5, and the movable frame 6 is correspondingly located at the top of the middle frame 18, and a groove corresponding to the middle frame 18 is provided at the center of the bottom surface of the movable frame 6, and the movable frame 6 slides on the top surface of the middle frame 18 through the groove, and a hose 19 is provided inside the middle frame 18, and clamps 20 are fixed at both ends of the hose 19, and the two clamps 20 are respectively rotatably clamped inside the two ends of the middle frame 18, and the top opening of the middle frame 18 corresponds to the hose 19, and connecting cavities are provided at both ends of the middle frame 18, and the end of the hose 19 is connected to the connecting cavity through the clamp 20, and the top of the water inlet pipe 9 is connected to the hose 19 through the connecting cavity and the clamp 20, and the bottom end of the boosting chamber 7 is fixed with a vertical pipe 21 connected to the hose 19, and the vertical pipe 21 is slidably matched with the top opening of the middle frame 18. The water pump passes the water inside the water tank 3 into the connecting cavity through the water inlet pipe 9. The water inside the connecting cavity enters the hose 19 through the clamp 20. The water that enters the hose 19 from the two clamps 20 directly enters the boosting cavity 7 through the vertical pipe 21. The water is pressurized by the boosting cavity 7, and then the pressurized water is directly sprayed out through the drain pipe 8. The water sprayed out from the drain pipe 8 flushes the bracket.

[0033] The spiral effect of the rotating rod 14 and the slider 17 makes the movable frame 6 move on the top of the cover frame 5, and the movable frame 6 drives the boost chamber 7 to move synchronously on the top of the cover frame 5. At this time, the boost chamber 7 uses the vertical pipe 21 to move inside the opening at the top of the middle frame 18. The moving vertical pipe 21 pulls and squeezes the hose 19, and the hose 19 is deformed inside the middle frame 18. Since the clamp 20 is rotated and clamped inside the middle frame 18, the clamp 20 is used to make the end of the hose 19 always connected to the corresponding connecting chamber, ensuring that the water inside the connecting chamber can enter the boost chamber 7 through the hose 19 and the vertical pipe 21.

[0034] exist Figure 5 and Figure 6 In the figure, a pressing plate 22 is also arranged inside the mobile frame 6, and the boost chamber 7 is placed on the top of the pressing plate 22, and the vertical pipe 21 at the bottom of the boost chamber 7 passes through the center of the pressing plate 22. Two side plates 23 are fixed to the bottom of the pressing plate 22, and the bottom ends of the two side plates 23 are both at the top opening of the middle frame 18, and the bottom ends of the side plates 23 correspond to the top of the hose 19, and the two side plates 23 are respectively located at the front and rear sides of the vertical pipe 21. Side rods 24 are fixed at both ends of the pressing plate 22, and the two side rods 24 pass through the vertical slots on both sides of the mobile frame 6, and a clamping rod 25 passing through the side rods 24 is fixed inside the vertical slot, and an elastic member 26 is sleeved on the surface of the clamping rod 25, and the bottom end of the elastic member 26 is connected to the bottom of the vertical slot, and the top end of the elastic member 26 is connected to the bottom of the side rod 24. An inverted U-shaped frame 27 is inserted on the top of the mobile frame 6, and both ends of the pressing plate 22 are fixedly connected to the bottom of the inner side of the U-shaped frame 27 by the side rods 24. The boost chamber 7 is placed on the top of the pressure plate 22. The weight of the boost chamber 7 on the pressure plate 22 causes the pressure plate 22 to move downward. At this time, the pressure plate 22 uses the side rods 24 to squeeze the elastic member 26 inside the vertical groove during the downward movement, and uses the clamping rod 25 itself to limit the side rods 24, so that the pressure plate 22 connected to the side rods 24 is always in a horizontal state on the inner side of the moving frame 6, thereby ensuring that the boost chamber 7 is in a horizontal state on the inner side of the moving frame 6, so that the drain pipe 8 of the boost chamber 7 is always in a horizontal state, which is convenient for the drain pipe 8 to fully flush the brackets at the same level.

[0035] exist Figure 1 , Figure 2 and Figure 5In the embodiment, a sleeve 28 is fixed on the top of the U-shaped frame 27, and a rubber rod 29 is arranged inside the sleeve 28. The rubber rod 29 is screwed into the sleeve 28, and the bottom end of the rubber rod 29 is in contact with the top surface of the boost chamber 7. After the boost chamber 7 is placed on the top surface of the pressure plate 22, the rubber rod 29 is rotated, and the rubber rod 29 moves down inside the sleeve 28 until the bottom end of the rubber rod 29 contacts the top surface of the boost chamber 7. At this time, the rubber rod 29 continues to move down inside the sleeve 28. The downwardly moved rubber rod 29 causes the boost chamber 7 to drive the pressure plate 22 to move down. The downwardly moved pressure plate 22 uses the side rod 24 to squeeze the elastic member 26 on the surface of the clamping rod 25. The elastic force of the elastic member 26 and the pressure of the rubber rod 29 are used to confine the boost chamber 7 inside the mobile frame 6, so as to prevent the boost chamber 7 from shaking inside the mobile frame 6 due to the recoil force of the water sprayed from the drain pipe 8.

[0036] When the external component impacts the top of the U-shaped frame 27, the downwardly moving U-shaped frame 27 drives the pressure plate 22 downwardly by using the side rod 24, and at the same time, the U-shaped frame 27 drives the rubber rod 29 downwardly by using the sleeve 28, and the pressure plate 22 and the rubber rod 29 make the booster chamber 7 and the drain pipe 8 move downward synchronously with the U-shaped frame 27, and the downwardly moving pressure plate 22 uses the side rod 24 to squeeze the elastic member 26 on the surface of the clamping rod 25, and uses the elastic force of the elastic member 26 to absorb the impact force of the external component, and at the same time, the downwardly moving pressure plate 22 drives the two side plates 23 to move downward synchronously. The bottom ends of the two side plates 23 are squeezed on the surface of the hose 19, and the hose 19 is deformed under pressure. At the same time, the two side plates 23 squeeze the hose 19 to block the water inlet of the hose 19 to the vertical pipe 21. At this time, the water in the hose 19 will not enter the boosting chamber 7 through the vertical pipe 21. When the boosting chamber 7 drives the drain pipe 8 to gradually enter the movable frame 6, the boosting chamber 7 will not discharge the water through the drain pipe 8, thereby avoiding the impact of water on the inner side of the movable frame 6 so that the water is scattered on the top of the cover frame 5, thereby reducing the waste of water resources.

[0037] Working principle of the present invention:

[0038] Reference Figures 1 to 6 As shown, the bracket to be flushed is placed on the ground, and the water tank 3 is connected to a water inlet faucet. When the faucet is turned on, water directly flows into the water tank 3. When the water tank 3 moves back and forth on the top of the track 1 using the wheels 4, the water tank 3 moving back and forth drives the boosting chamber 7 and the drain pipe 8 to move back and forth synchronously through the cover frame 5. The water pump passes the water inside the water tank 3 into the connecting chamber through the water inlet pipe 9. The water inside the connecting chamber enters the hose 19 through the clamp 20. The water that enters the hose 19 from the two clamps 20 directly enters the boosting chamber 7 through the vertical pipe 21. The water is pressurized by the boosting chamber 7, and then the pressurized water is directly sprayed out through the drain pipe 8. The water sprayed from the drain pipe 8 that moves back and forth flushes the bracket to be flushed.

[0039] Start the motor. When the motor is working, the motor output end drives the gear 15 to rotate. When the rotating gear 15 drives the adjacent gear 15 to rotate synchronously by the belt 16, the gear 15 drives the rotating rod 14 to rotate inside the side frame 13. At this time, the two rotating rods 14 rotate synchronously under the synchronous drive of the two adjacent gears 15. When the two rotating rods 14 rotate synchronously, due to the limitation of the slider 17 by the side frame 13 itself, the rotating rotating rod 14 makes the slider 17 move back and forth inside the side frame 13. The two synchronously rotating rotating rods 14 further make the sliders 17 inside the two side frames 13 move synchronously, and the movement of the slider 17 drives the moving frame 6 to move on the top of the cover frame 5. The spiral effect of the rotating rod 14 and the slider 17 is used to limit the moving frame 6, so as to prevent the counter-impact force of the water sprayed by the drain pipe 8 from causing the moving frame 6 to move on the top of the cover frame 5.

[0040] The spiral effect of the rotating rod 14 and the slider 17 makes the movable frame 6 move on the top of the cover frame 5, and the movable frame 6 drives the boost chamber 7 to move synchronously on the top of the cover frame 5. At this time, the boost chamber 7 uses the vertical pipe 21 to move inside the opening at the top of the middle frame 18. The moving vertical pipe 21 pulls and squeezes the hose 19, and the hose 19 is deformed inside the middle frame 18. Since the clamp 20 is rotated and clamped inside the middle frame 18, the clamp 20 is used to make the end of the hose 19 always connected to the corresponding connecting chamber, ensuring that the water inside the connecting chamber can enter the boost chamber 7 through the hose 19 and the vertical pipe 21.

[0041] The weight of the cover frame 5 is applied to the top of the float 11 through multiple vertical rods 10. When the float 11 moves downward inside the water tank 3, it cooperates with the protrusion to pull the spring 12 on the surface of the vertical rod 10, and the buoyancy of the float 11 itself inside the water tank 3 and the elastic force of the spring 12 cooperate to support the cover frame 5. When the water inside the water tank 3 gradually decreases until the liquid level of the water inside the water tank 3 corresponds to the bottom surface of the float 11, the water inside the water tank 3 continues to be sprayed out through the drain pipe 8, and the water level inside the water tank 3 gradually decreases. The weight of the cover frame 5 causes the float 11 at the bottom of the vertical rod 10 to move downward synchronously with the water surface, and the horizontal plane where the center line of the drain pipe 8 is located gradually moves downward. The liquid level of the water inside the water tank 3 is controlled to control the water spraying height of the drain pipe 8. At this time, the water sprayed from the drain pipe 8 can flush the different heights of the bracket.

[0042] When an external component impacts the top of the cover frame 5 and the cover frame 5 moves downward, the cover frame 5 pulls the spring 12 through the float plate 11 at the bottom of the vertical rod 10, and the floating plate 11 moves downward inside the water tank 3. The buoyancy of the water inside the water tank 3 on the float plate 11 and the elastic force of the spring 12 cooperate to absorb the power of the cover frame 5 moving downward, thereby preventing the bottom surface of the cover frame 5 from directly impacting the top surface of the water tank 3 and preventing the water tank 3 and the cover frame 5 from being damaged by impact. When the external component impacts the top of the U-shaped frame 27, the downwardly moving U-shaped frame 27 drives the pressure plate 22 downwardly by using the side rod 24, and at the same time, the U-shaped frame 27 drives the rubber rod 29 downwardly by using the sleeve 28, and the pressure plate 22 and the rubber rod 29 make the booster chamber 7 and the drain pipe 8 move downward synchronously with the U-shaped frame 27, and the downwardly moving pressure plate 22 uses the side rod 24 to squeeze the elastic member 26 on the surface of the clamping rod 25, and uses the elastic force of the elastic member 26 to absorb the impact force of the external component, and at the same time, the downwardly moving pressure plate 22 drives the two side plates 23 to move downward synchronously. The bottom ends of the two side plates 23 are squeezed on the surface of the hose 19, and the hose 19 is deformed under pressure. At the same time, the two side plates 23 squeeze the hose 19 to block the water inlet of the hose 19 to the vertical pipe 21. At this time, the water in the hose 19 will not enter the boosting chamber 7 through the vertical pipe 21. When the boosting chamber 7 drives the drain pipe 8 to gradually enter the movable frame 6, the boosting chamber 7 will not discharge the water through the drain pipe 8, thereby avoiding the impact of water on the inner side of the movable frame 6 so that the water is scattered on the top of the cover frame 5, thereby reducing the waste of water resources.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
