Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a low-speed, high-pressure three-dimensional rotating nozzle. Background Technology

[0002] Currently, large tanks, such as coal storage tanks, refining tanks, or purification tanks, are used extensively in the production processes of pharmaceuticals, chemicals, and food technologies. During daily use, these tanks accumulate oil, dust, oxides, and metal shavings on their surfaces. If not cleaned regularly, a dark brown layer forms on the tank surface, affecting not only the cleanliness of the workshop but also the hygiene of the tank surface, and in extreme cases, even causing corrosion. Therefore, timely cleaning of these tanks is essential. Traditional cleaning methods, especially for the internal cleaning of large tanks, often rely on manual entry into the tank. This method is not only inefficient and labor-intensive, but also creates blind spots and poses a serious safety hazard to operators. Existing cleaning equipment mostly uses water pipes to rinse at the tank inlet, which fails to thoroughly clean the inner walls of the tank, resulting in poor cleaning effects and often failing to achieve the desired cleaning results, with extremely low cleaning efficiency.

This equipment is mainly used for internal cleaning of large tanks and is suitable for areas that cannot be cleaned manually. It has high cleaning efficiency and good results, and does not damage the equipment, which can reduce costs significantly. Moreover, operators do not need to operate in high-risk environments, thus reducing the danger.

[0004] The solution adopted by this utility model to solve its technical problem is as follows: a low-speed, high-pressure three-dimensional rotating nozzle, including a housing, a lifting shaft seat rotatably mounted on the top of the housing, a drive unit, a rotating mechanism, and a speed regulating unit. A hollow main shaft is horizontally rotatably mounted on the housing, a water distribution plate is installed at the front end of the hollow main shaft, and a spray gun is eccentrically fixed on the side wall of the water distribution plate. A water pipe connector is installed at the lower end of the housing, and a water passage hole on the hollow main shaft communicates with the water pipe connector. The drive unit includes a main gear fixedly mounted on the rear end of the hollow main shaft, and a transmission component is provided inside the housing. The main gear is connected to the transmission component. The rotating mechanism includes a drive shaft rotatably mounted longitudinally inside the housing. The drive shaft is connected to the transmission component. A driven gear is fixedly mounted on the lower end of the drive shaft. A gear ring meshing with the driven gear is fixedly mounted on the water pipe connector.

[0005] The speed regulating unit includes a transmission shaft three that is longitudinally rotatably mounted on the upper part of the housing. The transmission shaft three is connected to the transmission assembly. An inner ring seat is fixedly installed on the upper end of the transmission shaft three, and multiple magnets are arranged circumferentially on the outer wall of the inner ring seat. An outer ring seat is longitudinally slidably mounted on the upper part of the housing above the transmission shaft three. A copper ring is arranged on the inner wall of the outer ring seat. The magnets are inserted into the copper ring. An adjusting bolt for adjusting the position of the outer ring seat is provided on the top of the housing.

[0006] Furthermore, the transmission assembly includes a worm gear rotatably mounted inside the housing and parallel to the hollow main shaft. A compound wheel is fixedly mounted on the rear end of the worm gear, and the main gear meshes with the compound wheel. A worm wheel is fixedly mounted on the upper end of the first transmission shaft, and the worm wheel meshes with the worm gear. A second transmission shaft rotatably mounted inside the housing and parallel to the worm gear is mounted on the second transmission shaft. A driven gear two that meshes with the compound wheel is fixedly mounted on the second transmission shaft, and a bevel gear one is fixedly mounted on the second transmission shaft. A bevel gear two is fixedly mounted on the lower end of the third transmission shaft, and the bevel gear two meshes with the bevel gear one.

[0007] Furthermore, the composite wheel includes gear one and gear two, with the main gear meshing with gear two and the driven gear two meshing with gear one.

[0008] Furthermore, the lifting shaft seat includes a mounting plate located at the lower end, the mounting plate being rotatably fitted onto the top of the housing, and an adjusting bolt being vertically mounted on the mounting plate, the outer ring seat being fixed on the adjusting bolt.

[0009] Furthermore, mounting holes are provided at the front end of the hollow spindle and at the corresponding positions of the water distribution plate. Mounting rods are inserted into the mounting holes, and the hollow spindle and the water distribution plate are mounted together by the mounting rods and nuts.

[0010] Furthermore, a positioning bolt is installed on the outer side of the outer shell, and a guide groove is longitudinally opened on the outer wall of the outer ring seat, with the inner end of the positioning bolt set in the guide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, by setting up a drive unit, a rotation unit, and a speed regulation unit, uses a high-pressure water jet spray gun for cleaning, resulting in good cleaning effect and achieving deep cleaning. Moreover, the eccentrically set spray gun drives the hollow main shaft to rotate when spraying water. With the transmission cooperation of the drive unit and transmission components, the equipment itself can rotate. The nozzle can automatically perform three-dimensional rotating water spraying inside the large tank, achieving comprehensive cleaning and ensuring that every corner of the inner wall of the tank is effectively cleaned, and greatly improving cleaning efficiency.

[0013] During the three-dimensional rotating water spraying process, the transmission components and the transmission shaft create a speed difference between the copper ring and the magnet, thereby generating an electromagnetic force between them. By adjusting the electromagnetic force between the magnet and the copper ring in the speed control unit, the rotation speed of the equipment can be flexibly controlled to adapt to different cleaning needs. During cleaning, operators do not need to enter the tank; the cleaning work can be completed through external operation, greatly reducing operational risks. Moreover, the equipment has a compact structure and is easy to install and use in different situations. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-7 This utility model provides a technical solution for a low-speed, high-pressure three-dimensional rotating nozzle: Example

[0024] according to Figure 1 , Figure 2 and Figure 3 As shown, the device includes a housing 1, on which a hollow main shaft 2 is horizontally rotatably mounted. The front end of the hollow main shaft 2 extends out of the housing 1 and a water distribution plate 3 is installed at the front end. Two spray guns 4 are fixedly installed around the periphery of the water distribution plate 3, and the spray guns 4 are eccentrically mounted on the side of the water distribution plate 3. A water pipe connector 5 is installed at the lower end of the housing 1, and the water inlet pipe of the water pipe connector 5 is perpendicular to the hollow main shaft 2 and communicates with its hollow interior through a water passage hole on the hollow main shaft 2. A lifting shaft seat 11 is installed at the upper end of the housing 1 and is fitted onto the top of the housing 1. During cleaning, a rope is used to lift the three-dimensionally rotating device through the lifting shaft seat 11 on the upper part of the device. The nozzle is placed inside the tank. The water pipe connector 5 at the bottom of the equipment is connected to the high-pressure water pipe. Water enters the hollow main shaft 2 through the water pipe connector 5 and then enters the water distribution plate 3. After the water jet enters the equipment, the equipment sprays water through the spray gun 4 to form a high-pressure water jet. Due to the eccentric setting of the spray gun 4, the high-pressure water jet sprayed by the spray gun 4 will drive the water distribution plate 3 and the hollow main shaft 2 to rotate at high speed, realizing two-dimensional water spraying. A rotating mechanism 7 is set inside the outer shell 1. When the hollow main shaft 2 rotates, the rotating mechanism 7 can be started by the drive unit 6. The rotating mechanism 7 drives the outer shell 1 to rotate along the Z-axis, thereby driving the spray gun part to form a cylindrical cleaning surface, realizing three-dimensional water spraying cleaning.

[0025] A drive unit 6 is provided inside the outer casing 1, such as Figures 4-6 As shown, the drive unit 6 includes a main gear 61 fixedly mounted on the rear end of the hollow main shaft 2. A worm gear 62 is rotatably mounted inside the housing 1, positioned at the upper end of the hollow main shaft 2 and parallel to it. A compound wheel, including a first gear 63 and a second gear 64, is located at the rear end of the worm gear 62. The main gear 61 meshes with the second gear 64 in the compound wheel, driving the worm gear 62 to rotate. A transmission shaft 71 is longitudinally rotatably mounted inside the housing 1. A worm wheel 72 is fixedly mounted on the upper end of the transmission shaft 71 and meshes with the worm gear 62. A driven gear 73 is fixedly mounted on the lower end of the transmission shaft 71. A gear ring 74 that meshes with the driven gear 73 is fixedly mounted on the water pipe connector 5. When the worm gear 62... During rotation, the meshing force of the worm gear 62 and the worm wheel 72 drives the drive shaft 71 and the driven gear 73 to rotate. At the same time, the meshing force of the driven gear 73 and the gear ring 74 enables the water pipe connector 5 to rotate. Since the water pipe connector 5 is limited and installed at the lower end of the outer shell 1, the rotation of the outer shell 1 and its internal structure can be realized through the cooperation of the drive unit 6 and the rotating mechanism 7, thereby realizing the Z-axis rotation of the nozzle. Furthermore, when the hollow main shaft 2 and the water distribution plate 3 rotate at high speed, a series of transmissions through the composite wheel, worm gear, gear ring, and other transmission structures can provide a reduction ratio, allowing the nozzle to rotate slowly while the hollow main shaft 2 is rotating at high speed, ensuring that the inner wall of the tank can be cleaned.

[0026] A rear cover plate 10 is provided at the rear of the outer casing 1. The hollow main shaft 2, drive shaft 71, drive shaft 81 and other structures can be installed in the outer casing 1 through the slot at the rear cover plate 10. The front ends of the hollow main shaft 2, worm gear 72 and drive shaft 81 are installed in the outer casing 1 through the bearing seat, and the rear ends are installed on the rear cover plate 10 through the bearing seat.

[0027] like Figure 2 As shown, mounting holes are provided at the front end of the hollow spindle 2 and at the corresponding positions of the water distribution plate 3. Mounting rods are inserted into the mounting holes. The hollow spindle 2 and the water distribution plate 3 can be installed together by mounting rods and nuts, thereby achieving the installation and fixation of the hollow spindle 2 and the water distribution plate 3.

[0028] A sealing gasket is installed at the connection between the hollow spindle and the water pipe connector inside the equipment to ensure that the water pipe connector can supply water to the hollow spindle and to prevent water leakage at the connection.

[0029] In practical use, the low-speed, high-pressure three-dimensional rotary nozzle of this utility model first connects a high-pressure water pipe to the lower part of the equipment via a water pipe connector 5, and then suspends the equipment in the tank via ropes and a lifting shaft seat 11. The high-pressure water pipe supplies water to the water distribution plate 3 through the water pipe connector 5 and the hollow main shaft 2, and the water is sprayed out at high pressure through the spray gun 4. Due to the eccentric setting of the spray gun 4, the spray gun 4 can drive the water distribution plate 3 and the hollow main shaft 2 to rotate at high speed during the high-pressure water spraying process. When the hollow main shaft 2 rotates, the meshing force between the main gear 61 and the compound wheel drives the worm 62 to rotate. Then, the meshing force between the worm 62 and the worm wheel 72 drives the transmission shaft 71 and the driven gear 73 to rotate. Then, the meshing force between the driven gear 73 and the gear ring 74 drives the outer shell 1 and the entire equipment to rotate around the Z-axis. Through a series of transmission decelerations, the equipment can rotate slowly. When the spray gun 4 sprays water at high speed, it forms a columnar spray surface to clean the inner wall of the tank. Example

[0030] Based on Embodiment 1, a speed regulating unit 8 is provided inside the equipment to facilitate adjustment of its rotational speed, such as... Figures 4-7As shown, the speed regulating unit 8 includes a second transmission shaft 81 rotatably mounted inside the outer casing 1. The second transmission shaft 81 is located at the upper end of the worm gear 62 and parallel to it. A second passive gear 82 that meshes with the first gear 63 in the compound wheel is fixedly mounted on the second transmission shaft 81. A first bevel gear 83 is also fixedly mounted on the second transmission shaft 81. A partition is provided inside the outer casing 1, which divides the inner part of the outer casing 1 into a lower drive cleaning area and an upper speed regulating area. An outer ring seat 88 is longitudinally slidably mounted in the speed regulating area, and a copper ring 89 is provided on the inner wall of the outer ring seat 88. A third transmission shaft 84 is longitudinally rotatably mounted on the partition via a shaft seat. A second bevel gear 85 is fixedly mounted on the lower end of the third transmission shaft 84, and the second bevel gear 85 meshes with the first bevel gear 83. An inner ring seat 86 is fixedly installed on the upper end of the third transmission shaft 84, and the inner ring seat 86 is movably mounted inside the outer ring seat 88. Multiple magnets 87 are arranged circumferentially on the outer wall of the inner ring seat 86. When the second transmission shaft 81 rotates, the meshing effect of the first bevel gear 83 and the second bevel gear 85 drives the inner ring seat 86 and the magnet 87 on it to rotate via the third transmission shaft 84. The outer ring seat 88 and the copper ring 89 on it rotate synchronously with the outer shell through the drive of the rotating mechanism 7. Since the transmission ratio of the rotating mechanism 7 is different from that of the speed regulating unit 8, and the transmission paths are also different, there will be a speed difference between the inner ring seat 86 that rotates with the third transmission shaft 84 and the outer ring seat 88 that rotates with the outer shell 1. That is, the rotation speed of the copper ring 89 and the rotation speed of the magnet 87 are inconsistent. Since the magnet rotates in the copper ring, it will generate an induced electromotive force. The induced current in the copper ring will generate its own magnetic field. This magnetic field interacts with the magnetic field of the magnet to generate an electromagnetic force. Therefore, when the magnet 87 rotates, it will affect the rotation speed of the outer ring seat 88 and the copper ring 89 through the electromagnetic force, and thus affect the rotation speed of the outer shell 1.

[0031] The lifting shaft seat 11 includes a mounting plate located at the lower end. The mounting plate is rotatably mounted on the top of the housing 1. An adjusting bolt 9 is vertically mounted on the mounting plate, and an outer ring seat 88 is fixed on the adjusting bolt 9. The height of the outer ring seat 88 can be adjusted by adjusting the adjusting bolt 9, thereby adjusting the distance between the magnet 87 and the copper ring 89. By adjusting the insertion depth of the magnet in the copper ring 89, the magnitude of the generated electromagnetic force can be adjusted, thereby achieving the effect of controlling the rotation speed of the equipment.

[0032] A positioning bolt 13 is installed on the outer side of the outer casing 1 at the position corresponding to the speed adjustment zone. A guide groove 12 is longitudinally opened on the outer wall of the outer ring seat 88. The inner end of the positioning bolt 13 is set in the guide groove 12. Through the cooperation of the guide groove 12 and the positioning bolt 13, the movement of the outer ring seat 88 can be guided when the adjusting bolt 9 adjusts the height of the outer ring seat 88, ensuring that the outer ring seat 88 can only move up and down.

[0033] In practical use, the low-speed, high-pressure three-dimensional rotary nozzle of this invention first adjusts the height of the outer ring seat 88 by adjusting bolt 9 and adjusts the depth of the magnet 87 inserted into the copper ring 89. When the hollow main shaft 2 drives the main gear 61 to rotate, the meshing force between the main gear 61 and the compound wheel can drive the worm gear 62 to rotate. Under the meshing force between the driven gear 2 82 and the compound wheel, the transmission shaft 2 81 and the bevel gear 1 83 are driven to rotate. Then, under the meshing force between the bevel gear 1 83 and the bevel gear 2 85, the inner ring seat 86 and the magnet 87 are driven to rotate. The rotation speed of the inner ring seat 86 is different from the rotation speed of the equipment, and a speed difference is formed between the magnet 87 and the copper ring 89, thereby forming an induced electromotive force between the magnet 87 and the copper ring 89. The induced current in the copper ring generates a magnetic field. This magnetic field interacts with the magnetic field of the magnet to generate an electromagnetic force, which in turn affects the rotation speed of the equipment. By adjusting the height of the outer ring seat 88 and the depth of the magnet 87 inserted into the copper ring 89 by adjusting bolt 9, the rotation speed of the equipment can be controlled.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
