Description

Technical Field

[0001] The invention relates to the technical field of nozzles, and in particular to a high-pressure jet nozzle. Background Art

[0002] High-pressure jet nozzles are mainly used in high-pressure jet systems. Their main working principle is high-pressure water jet technology: high-pressure water jets pressurize water to hundreds of atmospheres, and then convert it into high-speed micro-water jets through a spray device with a small aperture. This technology has the characteristics of low cleaning cost, fast speed, high cleaning rate, and no damage to the objects being cleaned.

[0003] Wide range of applications: High-pressure jet nozzles can be used in many fields, such as ship rust removal, ultra-high-pressure water jet cleaning, high-pressure water jet cutting, etc. In different application scenarios, the structure and performance of high-pressure jet nozzles may vary;

[0004] When used for high-pressure cleaning of lumens with different diameters, when cleaning the inner wall of the lumens, the cleaning effect of the nozzle varies due to the change of the diameter of the tube. The prior art has the following defects:

[0005] 1. The spray angle of the nozzle is fixed during spraying, resulting in a lack of fluid propulsion and decontamination ability during spraying, and more manpower is required to twist and pull the water spray pipe connected to the nozzle to drive the cleaning;

[0006] 2. The rotation direction of the nozzle itself is fixed, and the single-direction jet cleaning can easily lead to the position of stubborn particles not being covered. Summary of the invention

By twisting the direction of the jet rotation, stubborn particles can be quickly cleaned, so as to solve the problem that the spray angle of the existing high-pressure jet nozzle is fixed during spraying and the rotation direction of the nozzle itself is fixed, and the single-direction jet cleaning easily leads to the position of stubborn particles not being covered.

[0045] Combination Figure 3 , Figure 7As shown, the hydraulic drive torsion mechanism includes a first drive water tank 41, a water inlet pipe 411, a second rotating blade 4101, a drive shaft 4102, an arc-shaped tooth 4103, a gear ring 4104 and a reversing assembly. The first drive water tank 41 is fixedly mounted on one side of the top of the water storage tank 4, and the first drive water tank 41 is connected to the top of the water storage tank 4. The second rotating blade 4101 is fixedly mounted on the surface of the drive shaft 4102 and is located inside the first drive water tank 41. The arc-shaped tooth 4103 is fixedly mounted on the drive shaft 4 102 surface, the gear ring 4104 is fixedly installed on the top of the surface of the torsion tube 71 and meshes with the arc teeth 4103, a high-pressure rotary joint 8 is fixedly installed at the inner center of the fixed top plate 3, the bottom of the delivery pipe 7 is rotatably sealed with the torsion tube 71 through the high-pressure rotary joint 8, one end of the water inlet pipe 411 is connected to the top of the first drive water tank 41, and the other end is connected to the external water source through the electromagnetic valve, and the reversal component is arranged on the top of the water storage tank 4, which is used to reverse the torsion tube 71 after rebound twisting.

[0046] Specifically, the first driving water tank 41 can drain the water transported by the water inlet pipe 411, and the water flow impacts the rotating blade 2 4101, which can rotate through the inclination of its blades. The rotation of the rotating blade 2 4101 can drive the arc-shaped tooth 4103 on the top to rotate, and the arc-shaped tooth 4103 drives the gear ring 4104 meshing with it to rotate through the arc-shaped teeth. The rotation of the gear ring 4104 can drive the torsion tube 71 fixed thereto to rotate. At the same time, when the arc-shaped tooth 4103 rotates to separate from the gear ring 4104, the torsion tube 71 can rotate in the opposite direction through the mirror rebound of the reversing component, thereby achieving the effect of changing the direction of the spray rotation, and then reciprocatingly flushing and cleaning the more stubborn particles, thereby achieving a more efficient high-pressure cleaning effect. The water inlet pipe 411 can be electrically activated and controlled by an external water source through a solenoid valve.

[0047] like Figure 7 As shown, the reversing assembly includes a fixed plate 4105, an arc rod 4106, a toggle plate 4107 and a spring 4108. The fixed plate 4105 is fixedly mounted on one side of the top of the water storage tank 4, the arc rod 4106 is fixedly mounted on one side of the fixed plate 4105, the toggle plate 4107 is fixedly mounted on the surface of the torsion tube 71 and slidably cooperates with the arc rod 4106, and the spring 4108 is sleeved on the surface of the arc rod 4106, and one end of the spring is fixedly mounted on the toggle plate 4107, and the other end is fixedly mounted on the fixed plate 4105;

[0048] Since the fixed plate 4105 is fixed on the water tank 4, and the water tank 4 is in a non-rotating state, when the torsion tube 71 is driven and twisted by the toothed ring 4104, the toggle plate 4107 is driven to squeeze the spring 4108 to compress its elastic force. When the toothed ring 4104 is separated from the arc-shaped tooth 4103, the elastic force of the spring 4108 can be released. After the elastic force is released, the toggle plate 4107 is driven to drive the torsion tube 71 to reverse twist, thereby realizing reverse twisting of the water jet, which greatly improves the automatic and efficient cleaning effect of the high-pressure jet nozzle.

[0049] Combination Figure 3 , Figure 4 , Figure 5 As shown, the multiple hydraulic drive mechanism includes a second drive water tank 42, a delivery hose 412, a return pipe 421, a worm 422 and a rotating blade 423. The second drive water tank 42 is provided with five groups, and the five groups of second drive water tanks 42 are distributed in a ring shape and equidistantly on the top of the mounting base 6. One end of the delivery hose 412 is connected to the first drive water tank 41, and the other end is connected to the bottom of the water storage tank 4. The return pipe 421 is connected to the bottom of the second drive water tank 42. The rotating blade 423 is fixedly installed on the top of the surface of the worm 422 and is located inside the second drive water tank 42.

[0050] Specifically, the second driving water tank 42 can facilitate the water flow inside the water tank 4 to enter through the delivery hose 412. At the same time, the water flow can impact the rotating blade 423 and cooperate with the blade inclination of the rotating blade 423 to make it rotate, thereby driving the worm 422 to rotate. After the worm 422 rotates, it can drive the worm gear 52 to realize the power conversion output, and cooperate with the nozzle injection angle follower mechanism to swing the swing nozzle 62 to drive the injection, thereby further ensuring the automatic and efficient cleaning effect of the high-pressure jet nozzle.

[0051] Combination Figure 5 , Figure 6 As shown, the nozzle spray angle follower mechanism includes a mounting bar 5, a rotating shaft 51, a worm gear 52, a driving disk 53, a slide rod 54, a swing amplitude adjustment component and a driving frame 55. The mounting bar 5 is detachably mounted inside the mounting base 6, the rotating shaft 51 is rotatably mounted on one side of the mounting bar 5, the worm gear 52 is fixedly mounted on the surface of the rotating shaft 51, the driving disk 53 is fixedly mounted on the side of the worm gear 52 away from the mounting bar 5, the slide rod 54 is slidably mounted inside the driving disk 53, the driving frame 55 is fixedly mounted on the side of the swing nozzle 62 close to the worm gear 52, and is slidably matched with the slide rod 54, the swing amplitude adjustment component is arranged inside the driving disk 53, and is used to adjust the position of the slide rod 54 away from the center of the driving disk 53, and the worm wheel 52 is meshed with the worm 422.

[0052] Specifically, the mounting bar 5 can mount the rotating shaft 51 on the mounting base 6, thereby ensuring the stability of the drive. At the same time, the worm wheel 52 can drive the driving disk 53 to rotate after being driven by the worm 422, and then drive the sliding rod 54 to rotate around the center of the driving disk 53 through the driving disk 53. After the sliding rod 54 rotates, it drives the driving frame 55 that slides with it to swing up and down, and then drives the swinging nozzle 62 through the driving frame 55 to swing and spray at an angle around the limiting axis frame 61.

[0053] like Figure 6 As shown, the swing amplitude adjustment component includes a limit block 541 and an inner hexagon adjusting bolt 542, the limit block 541 is fixedly installed on the driving disk 53, the inner hexagon adjusting bolt 542 is rotatably installed inside the limit block 541, and one end of the inner hexagon adjusting bolt 542 passes through the slide bar 54 and is threadedly connected to the slide bar 54; specifically, the limit block 541 can be installed to rotationally limit the inner hexagon adjusting bolt 542, and at the same time, by twisting the inner hexagon adjusting bolt 542 before installing the driving disk 53, the slide bar 54 is driven to move closer to or away from the center of the driving disk 53 under the limit of the driving disk 53, and the position of the slide bar 54 can be adjusted to change the operation of the swing range of the driving frame 55, thereby realizing the adjustment of the swing amplitude of the swing nozzle 62 of the high-pressure jet nozzle.

[0054] Combination Figure 3 , Figure 7 As shown, the return water assembly includes a main return water hard pipe 416, a return water hose 424 and a return water tank 425. One end of the return water hose 424 is connected to the return water pipe 421, and the other end passes through the water storage tank 4 and extends to the top of the water storage tank 4 and is connected to the return water tank 425. The main return water hard pipe 416 is connected to the top of the return water tank 425, and the other end of the main return water hard pipe 416 away from the return water tank 425 passes through the interior of the delivery pipe 7 and is connected to the external water tank. The return water tank 425 is rotatably mounted on the surface of the torsion tube 71; the return water hose 424 can transport the five groups of water flows returning through the return water pipe 421 to the return water tank 425, and then uniformly transport them to the external water tank through the main return water hard pipe 416 for recycling.

[0055] The top of the mounting base 6 is fixedly mounted with five groups of second drive water tanks 42 by bolts, and both sides of the water tank 4 are threadedly connected with hexagonal bolts and cooperate with the cover shell 2 for sliding limit. The second drive water tank 42 can be fixed with the mounting base 6 to ensure that it is more stable during the hydraulic drive conversion process. At the same time, the five groups of second drive water tanks 42 can be twisted along with the mounting base 6. The synchronous twisting tube 71 twists while driving the swing nozzle 62 to spray and clean at a changed angle, which greatly improves the cleaning effect of the high-pressure jet nozzle.

[0056] like Figure 3As shown, a fixing plate 63 is fixedly installed at the bottom of the mounting base 6, and the mounting base 6 is fixedly installed on the surface of the torsion tube 71. The fixing plate 63 rotates with the bottom of the worm 422. One end of the swing nozzle 62 is connected with a connecting hose 64. The swing nozzle 62 is connected to the bottom of the torsion tube 71 through the connecting hose 64, and the top of the torsion tube 71 is connected to the delivery pipe 7; a limiting axis frame 61 is fixedly installed on the surface of the mounting base 6 on both sides of the swing nozzle 62, and the inside of the limiting axis frame 61 rotates with the swing nozzle 62 through a latch; specifically, the fixing plate 63 can limit the rotation of the bottom of the worm 422 after being fixed to the mounting base 6 to ensure the rotation stability of the worm 422. At the same time, the connecting hose 64 can ensure the supply of water to the swing nozzle 62 when it swings, and stably perform angle spraying and cleaning. The limiting axis frame 61 can keep the swing nozzle 62 rotating around the axis pin in its limiting axis frame 61 when rotating, so that the swing nozzle 62 is more stable when the angle swings.

[0057] Working principle: before performing the cleaning operation, the expansion of the arc plate 106 is adjusted according to the diameter of the cavity tube. After the twisting rotating sleeve block 104 is close to the rotating fixed sleeve 101, it can drive the rotating ring 103 that rotates with it to move closer to the fixed sleeve 101. At the same time, through the hinge connection between the rotating ring 103 and the scissor-type telescopic frame 105, the two ends of the scissor-type telescopic frame 105 close to the threaded tube 102 are contracted, thereby driving the arc plate 106 to expand outward, and then adapt to different cavity tube diameters, so that the delivery pipe 7 is always in the center of the cavity tube, ensuring the stability of the high-pressure jet nozzle during high-pressure cleaning; then the water inlet pipe 411 is connected to the external high-pressure water source through the solenoid valve, and then the main return water hard pipe 416 is connected to the external water tank. The water flow of the external high-pressure water source is drained to the inside of the first driving water tank 41 through the water inlet pipe 411. The water flow impacts the rotating blade 2 4101, which can rotate through the inclination of its blades. The rotation of the second rotating blade 4101 can drive the arc-shaped tooth 4103 at the top to rotate, and the arc-shaped tooth 4103 drives the gear ring 4104 meshing with it to rotate through the arc-shaped teeth, and the rotation of the gear ring 4104 can drive the torsion tube 71 fixed thereto to rotate; at the same time, when the arc-shaped tooth 4103 rotates to separate from the gear ring 4104, the fixed plate 4105 is fixed on the water storage tank 4, and the water storage tank 4 is in a non-rotating state. At this time, when the torsion tube 71 is driven and twisted by the gear ring 4104, it drives the toggle plate 4107 to squeeze the spring 4108 to compress its elastic force, and when the gear ring 4104 is separated from the arc-shaped tooth 4103, the elastic force of the spring 4108 can be released. After the elastic force is released, the toggle plate 4107 is elastically driven to drive the torsion tube 71 to reversely twist, thereby realizing reverse twisting of the jet water flow, achieving the effect of changing the jet rotation direction, and then reciprocatingly flushing and cleaning the more stubborn particles, thereby realizing a more efficient high-pressure cleaning effect;

[0058] After the water flows through the first driving water tank 41 and enters the interior of the water storage tank 4, it flows through the delivery hose 412 and enters the interior of the five groups of second driving water tanks 42. At the same time, the water flows can impact the rotating blade 423 and rotate with the blade inclination of the rotating blade 423, thereby driving the worm 422 to rotate. After the worm 422 rotates, it can drive the worm gear 52 to realize the power conversion output. After being driven by the worm 422, the worm gear 52 can drive the driving disk 53 to rotate, and then the driving disk 53 drives the sliding rod 54 to rotate around the center of the driving disk 53. After the sliding rod 54 rotates, it drives the driving frame 55 that slides with it to swing up and down, and then the driving frame 55 drives the swing nozzle 62 to swing and spray around the limiting axis frame 61 at an angle, thereby improving the coverage of the cleaning surface of the inner wall of the cavity tube and avoiding repeated manual operations.
