A self - speed - regulating ultra - high - pressure water jet rotary nozzle

Abstract

The present invention provides a self - speed - adjustable ultra - high - pressure water jet rotary nozzle applied to the technical field of cleaning equipment. Through a servo motor, according to requirements, the required rotation speed of the nozzle is adjusted in real time. When friction cleaning and scraping are required, an air cylinder is operated to drive a push disk, compressing the storage bag between the storage disk and the rotating disk, so that the cleaning brush in the storage bag extends out. The extended cleaning brush rotates synchronously with the rotating spray rod, effectively improving the cleaning ability of the nozzle. At the same time, the movable plug on the rotating disk is pushed into the water valve sleeve at the end of the rotating spray rod, driving the sealing plug to separate from the water valve sleeve, connecting the water valve sleeve with the water injection pipeline, shunting the high - pressure water in the rotating spray rod, achieving the purpose of reducing water pressure, reducing the operation difficulty of the cleaning brush. The shunted high - pressure water is sprayed out from the cleaning nozzles at both ends of the cleaning brush, effectively improving the cleaning ability of the cleaning brush, and at the same time preventing debris from adhering to the cleaning brush, facilitating the subsequent recovery of the cleaning brush into the storage bag.

Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and particularly to a self-speed-adjusting ultra-high-pressure water jet rotary nozzle. Background Art

[0002] During the voyage of a ship, the surface of the hull below the waterline will be corroded by the chloride ions in the seawater salt due to the seawater. At the same time, the ship sails or anchors in the marine biological environment for a long time, making it difficult to remove microorganisms such as barnacles, oysters, bryozoans, and seaweeds attached to the part of the hull below the waterline. In this way, the smoothness of the hull surface is greatly affected, the resistance during forward movement in water increases significantly, resulting in a decrease in ship speed and a significant increase in fuel consumption. Generally, the cleaning of the hull is carried out by sandblasting or the method of using a high-pressure water gun in combination with manual scraping. Specifically, first, the sea salt on the hull is rinsed with high-pressure fresh water, then the rust scale and the cracked paint film are removed through sandblasting operations, and then paint is sprayed and brushed on the hull surface.

[0003] The sandblasting method will generate a large amount of dust, pollute the environment, and seriously endanger the health of operators. Using this method for cleaning for a long time will damage the hull surface, the cleaning site is troublesome, and at the same time, it will also generate relatively high noise. Therefore, it is very difficult to promote this cleaning method. Then there is the high-pressure water flushing method. Since the high-pressure water is ejected from the water gun, the reaction force brought by the water flow will be very high. The staff needs to hold the water gun with both hands to flush the hull, so another staff member is required to carry out the manual scraping work, which wastes labor and increases the workload, seriously reducing the cleaning efficiency of the ship. If a brush for cleaning is directly installed on the water gun nozzle, the brush will affect the ejection of the water flow, and the ultra-high water pressure will also affect the use of the brush. Forcing the use of the brush under high water pressure is also likely to cause harm to the staff.

[0004] In response to the above problems, this application makes a technical conjecture. A brush for cleaning is installed on the nozzle of the water gun. In order to prevent the brush from affecting the use of the nozzle, the brush is in a retracted state when the water gun is performing high-pressure water spraying operations, and the brush is extended when cleaning and scraping is required. At the same time, the water pressure is reduced to reduce the operation difficulty and protect the safety of the staff. Summary of the Invention

[0005] The purpose of this application is to improve the working ability of the nozzle and improve work efficiency. Compared with the prior art, a self-speed-adjusting ultra-high-pressure water jet rotary nozzle is provided. A servo motor is fixedly connected to the top of the power end of the spray rod, and the servo motor is movably connected to the rotating shaft. A spray rod fixing frame is fixedly connected to the rear of the power end of the spray rod. A storage tray is fixedly connected to the rear side of the rotating spray rod, and a storage bag is fixedly connected to the rear side of the storage tray. A rotating disk is fixedly connected to the rear of the storage bag. A cleaning brush is fixedly connected to the inside of the storage bag, and the cleaning brush is detachably connected to the rotating disk. A pushing disk is movably connected to the rear of the rotating disk. A pneumatic cylinder is fixedly connected to the top of the spray rod fixing frame, and the output end of the pneumatic cylinder is in transmission connection with the pushing disk; a water valve sleeve is fixedly inlaid at the end of the rotating spray rod, and the water valve sleeve is fixedly communicated with the water injection pipeline. A movable plug is sleeved inside the water valve sleeve, and the outer end of the movable plug is fixedly connected to the rotating disk. A sealing plug is fixedly connected to the inner end of the movable plug, and the sealing plug corresponds to the inner end inlet of the water valve sleeve. Cleaning nozzles are fixedly connected to both ends of the cleaning brush, and a pressure relief pipe is fixedly connected between the top of the water valve sleeve and the cleaning nozzles.

[0006] It is realized that through the servo motor, according to requirements, the required rotation speed of the nozzle is adjusted in real time. When friction cleaning is required, the pneumatic cylinder is operated to drive the pushing disk to compress the storage bag between the storage tray and the rotating disk, so that the cleaning brush in the storage bag extends out. The cleaning ability of the nozzle is improved through the cleaning brush. At the same time, the movable plug on the rotating disk is pushed into the water valve sleeve at the end of the rotating spray rod, so that the water valve sleeve is communicated with the water injection pipeline, and the high-pressure water in the rotating spray rod is shunted, achieving the purpose of reducing the water pressure, reducing the operation difficulty of the cleaning brush. The shunted high-pressure water is sprayed out from the cleaning nozzles at both ends of the cleaning brush, effectively improving the cleaning ability of the cleaning brush, and at the same time preventing sundries from adhering to the cleaning brush, facilitating the subsequent recovery of the cleaning brush into the storage bag.

[0007] Furthermore, the rotating spray rod is arranged in a cross shape, and gemstone nozzles are arranged on the surface of the rotating spray rod. The gemstone nozzles are communicated with the water injection pipeline. The cross-shaped rotating spray rod and the gemstone nozzles on the surface cooperate to increase the working area of the high-pressure water flow ejected, thereby improving the cleaning efficiency.

[0008] Furthermore, telescopic sleeves are sleeved on the four corners of the storage bag, and the front and rear ends of the telescopic sleeves are respectively fixedly connected to the storage tray and the rotating disk. The telescopic sleeves support and expand the four corners of the storage bag, facilitating the unfolding of the storage bag, and thus facilitating the use of the cleaning brush. At the same time, the telescopic sleeves realize the transmission between the storage tray and the rotating disk, facilitating the synchronous rotation of the storage tray and the rotating disk.

[0009] Furthermore, the storage bag is made of elastic rubber material, and the middle part of the storage bag bulges outwards. The cleaning brush is made of stainless steel wire. The storage bag made of elastic rubber material has good deformation ability. The shape of the middle part bulging outwards is convenient for the storage bag to be squeezed and shrunk.

[0012] Optionally, a pressure relief end head is fixedly connected to the outside of the metal protection pipe, and the pressure relief end head is fixedly communicated with the pressure relief pipe. The middle part of the pressure relief pipe is further shunted through the pressure relief end head, further reducing the water pressure.

[0013] Furthermore, a self-cleaning nozzle is fixedly connected to the bottom of the pressure relief end head, and the self-cleaning nozzle faces the rotating shaft. The self-cleaning nozzle sprays water towards the rotating shaft direction to realize the self-cleaning of the inside of the rotating nozzle, effectively avoiding sundries adhering to the rotating shaft and avoiding affecting the normal use of the nozzle.

[0014] Furthermore, a pressure relief nozzle is fixedly connected to the top of the pressure relief end head, and an adjusting screw is threadedly connected to the outside of the pressure relief nozzle. Water is sprayed from the top of the pressure relief end head through the pressure relief nozzle. While achieving the purpose of reducing the water pressure, the sprayed water has the same direction as the water ejected from the nozzle, and also plays a role in cleaning.

[0015] Furthermore, the pressure relief nozzle is arranged in a T shape. An adjusting plug is movably connected to the inner end of the adjusting screw, and the adjusting plug is movably connected to the pressure relief nozzle. By rotating the adjusting screw, the adjusting plug is pushed, and the flow space of the pressure relief nozzle is adjusted by using the adjusting plug, so as to realize the adjustment of the water output of the pressure relief nozzle, which is convenient for the regulation and use of the pressure relief nozzle.

[0016] Compared with the prior art, the advantages of this application are as follows:

[0017] (1) In this solution, through the servo motor, the required rotation speed of the nozzle is adjusted in real time according to the demand. When friction cleaning and scraping are required, the pneumatic cylinder is operated to drive the pushing disc to compress the storage bag between the storage disc and the rotating disc, so that the cleaning brush in the storage bag extends out. The cleaning ability of the nozzle is improved through the cleaning brush. At the same time, the movable plug on the rotating disc is pushed into the water valve sleeve at the end of the rotating spray bar, so that the water valve sleeve is communicated with the water injection pipeline, and the high-pressure water in the rotating spray bar is shunted, achieving the purpose of reducing the water pressure, reducing the operation difficulty of the cleaning brush. The shunted high-pressure water is ejected from the cleaning nozzles at both ends of the cleaning brush, effectively improving the cleaning ability of the cleaning brush, and at the same time avoiding sundries adhering to the cleaning brush, which is convenient for the subsequent recovery of the cleaning brush into the storage bag.

[0018] (2) The rotating spray bar is arranged in a cross shape, and gem nozzles are provided on the surface of the rotating spray bar. The gem nozzles are connected to the water injection pipeline.

[0023] (7) A pressure relief end is fixedly connected to the outside of the metal protection pipe, and the pressure relief end is fixedly communicated with the pressure relief pipe. The pressure relief end realizes the secondary diversion of the middle part of the pressure relief pipe, further reducing the water pressure.

[0024] (8) A self-cleaning nozzle is fixedly connected to the bottom of the pressure relief end, and the self-cleaning nozzle faces the rotating shaft. The self-cleaning nozzle sprays water towards the rotating shaft direction to realize the self-cleaning of the inside of the rotating nozzle, effectively preventing sundries from adhering to the rotating shaft and avoiding affecting the normal use of the nozzle.

[0025] (9) A pressure relief nozzle is fixedly connected to the top of the pressure relief end, and an adjusting screw is threadedly connected to the outside of the pressure relief nozzle. The pressure relief nozzle realizes the spraying of water from the top of the pressure relief end. While achieving the purpose of reducing the water pressure, the sprayed water has the same direction as the water ejected from the nozzle, also serving the purpose of cleaning.

A push frame 21 is movably connected to the outside of the spray bar fixing bracket 7, and the push frame 21 is connected to the push disc 12 through a push blade 22. The pneumatic cylinder 13 transmits the thrust to the push disc 12 through the push frame 21, improving the stable horizontal movement effect of the push disc 12 and facilitating the smooth extension of the cleaning brush 11;

[0042] Please refer to Figures 6-8, a water valve sleeve 14 is fixedly inlaid at the end of the rotating spray bar 3, and the water valve sleeve 14 is fixedly communicated with the water injection pipeline 4. An activity plug 15 is sleeved inside the water valve sleeve 14, and the outer end of the activity plug 15 is fixedly connected with the rotating disc 10. The inner end of the activity plug 15 is fixedly connected with a sealing plug 16, and the sealing plug 16 corresponds to the inner end opening of the water valve sleeve 14. When the activity plug 15 is pushed into the water valve sleeve 14 at the end of the rotating spray bar 3, the sealing plug 16 is separated from the water valve sleeve 14, the internal space of the water valve sleeve 14 is communicated with the water injection pipeline 4, high-pressure water flow enters the water valve sleeve 14 and then is discharged from the pressure relief pipe 18. Cleaning nozzles 17 are arranged at both ends of the cleaning brush 11. A pressure relief pipe 18 is fixedly connected between the top of the water valve sleeve 14 and the cleaning nozzles 17. Water enters the cleaning nozzles 17 from the pressure relief pipe 18, and high-pressure water is sprayed out from the cleaning nozzles 17 at both ends of the cleaning brush 11. The water flow improves the cleaning quality of the cleaning brush 11, and at the same time, it can also prevent sundries from adhering to the cleaning brush 11, facilitating the subsequent use of the cleaning brush 11. The pressure relief pipe 18 is made of rubber material and has good deformation and bending ability, which is convenient for the laying of the pressure relief pipe 18. A metal protection pipe 23 is fixedly sleeved in the middle section of the pressure relief pipe 18. The metal protection pipe 23 protects the exposed middle part of the pressure relief pipe 18, effectively preventing the middle part of the pressure relief pipe 18 from being damaged;

[0043] Please refer to Figures 9-10 , a pressure relief end 24 is fixedly connected to the outside of the metal protection pipe 23, and the pressure relief end 24 is fixedly communicated with the pressure relief pipe 18. The middle part of the pressure relief pipe 18 is further shunted through the pressure relief end 24 to further reduce the water pressure. A self-cleaning nozzle 25 is fixedly connected to the bottom of the pressure relief end 24, and the self-cleaning nozzle 25 faces the rotating shaft 2.

The inner end of the adjusting screw 27 is movably connected with an adjusting plug 28, and the adjusting plug 28 is movably connected with the pressure relief nozzle 26. By rotating the adjusting screw 27, the adjusting plug 28 is pushed. The inner end of the adjusting plug 28 is arranged in an inclined plane corresponding to the water inlet end of the pressure relief nozzle 26.

[0044] Working principle: When using this nozzle, install the nozzle on the cleaning equipment. Connect the rotating body 5 to the water inlet pipe. High-pressure water enters the rotating spray bar 3 through the rotating body 5 and sprays out from the gem nozzle 19 on the rotating spray bar 3 to wash the surface of the ship with the high-pressure water flow. At the same time, operate the servo motor 6 to adjust the required rotation speed of the rotating spray bar 3 in real time according to the needs. When brushing work is required, operate the pneumatic cylinder 13 to drive the push disk 12 to flatten the storage bag 9 between the compressed storage disk 8 and the rotating disk 10, so that the cleaning brush 11 in the storage bag 9 extends out. The cleaning brush 11 rotates with the rotating spray bar 3 to perform brushing operations on the area to be brushed. During the process of flattening the storage bag 9, the movable plug 15 on the rotating disk 10 is pushed into the water valve sleeve 14, thereby driving the sealing plug 16 to separate from the water valve sleeve 14. The internal space of the water valve sleeve 14 is connected to the water injection pipeline 4, and high-pressure water flows into the water valve sleeve 14 and then discharges from the pressure relief pipe 18 to achieve the purpose of relieving the pressure of the water outlet of the nozzle, reducing the reaction force of the high-pressure water, reducing the operation difficulty of the cleaning brush 11. The water entering the pressure relief pipe 18 sprays out from the cleaning nozzles 17 at both ends of the cleaning brush 11. The sprayed water corresponds to the brushing work of the cleaning brush 11, improving the cleaning ability of the cleaning brush 11 and simultaneously flushing the sundries attached to the cleaning brush 11.
