Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a high-pressure water jet cleaning device. Background Technology

[0002] High-pressure water jet cleaning technology, as a highly efficient, environmentally friendly, and widely used cleaning method, has been rapidly promoted in many fields in recent years. It uses a high-pressure water generator to pressurize water to hundreds of atmospheres or more, and then converts it into a high-speed micro-water jet through a fine-aperture jetting device. Its speed is usually above Mach 1, which has huge impact energy and can complete a variety of cleaning tasks. This technology has many advantages such as low cleaning cost, fast speed, high cleaning rate, no damage to workpieces, wide range of applications, and no environmental pollution. It is gradually replacing the polluting chemical cleaning methods and is highly favored in industries such as power generation, petroleum, chemical, casting, nuclear power plants, airports, and cement.

[0003] Currently, there are various high-pressure water jet cleaning devices on the market. However, the existing cleaning devices have obvious limitations in terms of handle design. Most of them adopt a fixed handle structure, which makes it impossible for operators to flexibly adjust the handle position to optimize the operating experience and cleaning effect when facing different cleaning tasks.

[0004] In scenarios requiring precise control and low-load operation, such as cleaning the surface of precision instruments, the fixed handle position and long lever arm require operators to apply considerable force to complete delicate movements. This not only increases labor intensity but also easily damages the parts being cleaned due to excessive torque. Furthermore, when dealing with the backlash force generated by high-pressure water flow, the hand is far from the "force application point" of the nozzle, making it difficult to quickly and effectively counteract the backlash force. This leads to increased hand displacement error and seriously affects the stability of the cleaning process. It is not suitable for tasks that require extremely high spray stability, such as cleaning cultural relics and removing adhesive from circuit boards.

[0005] On the other hand, in scenarios that require high torque output, such as removing thick scale from the inner walls of pipes, the fixed handle makes it difficult for operators to use the lever arm advantage to generate enough torque to break up hard scale. At the same time, when dealing with potentially dangerous cleaning tasks such as strong acids, high temperatures or harmful substances, the handle cannot be moved back, which limits the safe distance between the operator and the spray area. Even when wearing protective equipment, there is still a high risk of chemical splashes and high-temperature burns, which cannot meet the requirements of relevant safety standards for physical protection distance.

[0006] In summary, existing high-pressure water jet cleaning devices have significant shortcomings in terms of operational flexibility, job adaptability, and safety due to the non-adjustable handle position, and cannot fully meet diverse actual cleaning needs. There is an urgent need for an innovative design that can adjust the handle position to improve this situation. Utility Model Content

[0007] The purpose of this invention is to provide a high-pressure water jet cleaning device that allows for adjustable handle positions, enabling operators to flexibly adjust the device for different cleaning tasks and optimize the operating experience and cleaning effect.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A high-pressure water jet cleaning device includes a high-pressure pump and a hose. The output end of the high-pressure pump and the hose are connected by a connecting pipe. The device is characterized in that: a spray head is installed at the end of the hose away from the connecting pipe, and first mounting plates are installed vertically on the outer side of the hose and the side close to the spray head. The two first mounting plates are fixedly connected, and a truss is fixed to the first mounting plate located at the lower part of the hose.

[0010] A second mounting plate and a third mounting plate are respectively installed on the outer side of the hose and at the end of the first mounting plate away from the spray head. The second mounting plate and the third mounting plate are fixedly connected. A fixing frame is fixed to the bottom of the third mounting plate. A slide bar is provided in the fixing frame and is slidably connected to the truss. A locking structure for locking the position of the third mounting plate is installed in the fixing frame.

[0011] The locking structure includes a threaded rod threaded to the bottom of the fixing frame. The truss has multiple threaded grooves adapted to the threaded rod, and the threaded rod is inserted into one of the threaded grooves and threadedly connected to the threaded groove.

[0012] A second handle is fixed to the bottom of the truss and below the first mounting plate, and a first handle is fixed to the bottom of the threaded rod.

[0013] A first spring is installed between the first grip and the fixed frame, and on the outside of the threaded rod.

[0014] The top of the truss is provided with a sliding groove, and the sliding groove is connected to a plurality of threaded grooves. The top of the threaded rod is fixed with an abutment strip, and the abutment strip is inserted into the sliding groove. The inner wall of the third mounting plate is slidably connected with an abutment piece, and the bottom of the abutment piece is fixed with a sliding strip, which passes through the third mounting plate and extends into the sliding groove. A reset structure is installed between the truss and the sliding strip.

[0015] The reset structure includes a sliding plate slidably connected to the top of the truss, and the sliding plate is slidably connected to the sliding bar. A fixing plate is fixed on the outside of the sliding bar and on the top of the sliding plate. A second spring is assembled between the fixing plate and the sliding plate and on the outside of the sliding bar.

[0016] Both the second mounting plate and the third mounting plate have magnet strips on the side that is close to the first mounting plate.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention, through the setting of a fixing frame, allows the first handle to be screwed on when adjusting, thereby locking the fixing frame onto the truss. This allows for adjustment of the handle position, enabling operators to flexibly adjust it in different cleaning tasks, optimizing the operating experience and cleaning effect. When dealing with recoil force, the hand is close to the "force application point" to quickly counteract the recoil force and reduce hand displacement error. In high-torque scenarios, it can generate sufficient torque by utilizing the lever arm advantage. In dangerous scenarios, the handle is moved back to increase the safety distance and meet safety standards. Attached Figure Description

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-5 As shown, a high-pressure water jet cleaning device includes a high-pressure pump 1 and a hose 2. The output end of the high-pressure pump 1 and the hose 2 are connected by a connecting pipe 3. A spray head 4 is installed at the end of the hose 2 away from the connecting pipe 3. When it is necessary to clean an object, the high-pressure pump 1 can be driven to absorb water and transmit it through the connecting pipe 3, thereby allowing the water to be conducted to the hose 2. The spray head 4 can spray water to clean the object. First mounting plates 5 are installed on the outer side of the hose 2 and the side close to the spray head 4. The two first mounting plates 5 are fixedly connected. A truss 9 is fixed to the first mounting plate 5 located at the lower part of the hose 2.

[0028] A second mounting plate 6 and a third mounting plate 7 are respectively installed on the outer side of the hose 2, at the end of the first mounting plate 5 away from the spray head 4, and the second mounting plate 6 and the third mounting plate 7 are fixedly connected. See Appendix. Figure 5 The two first mounting pieces 5, the second mounting piece 6, and the third mounting piece 7 are connected by rivets. When it is not necessary to extend the grip, the first mounting pieces 5, the second mounting pieces 6, and the third mounting pieces 7 can be removed. The user can then hold the hose 2 to achieve the spray cleaning effect. The second mounting pieces 6 and the third mounting pieces 7 are provided with magnetic strips 23 on the side close to the first mounting piece 5. The magnetic poles of the magnetic strips 23 on the first mounting piece 5 are opposite to those on the second mounting pieces 6 and the third mounting pieces 7, so they can attract each other. By setting the magnetic strips 23, when the first mounting pieces 5, the second mounting pieces 6, and the third mounting pieces 7 are removed and stored, the magnetic strips 23 attract the second mounting pieces 6 and the third mounting pieces 7 to the first mounting piece 5, reducing the storage space caused by the second mounting pieces 6 and the third mounting pieces 7. The bottom of the third mounting piece 7 is fixed with a fixing frame 8. The fixing frame 8 is provided with a sliding strip 12, and the sliding strip 12 is slidably connected to the truss 9. The fixing frame 8 is equipped with a locking structure for locking the position of the third mounting piece 7.

[0029] When it is necessary to adjust the user's grip position, the third mounting plate 7 and the second mounting plate 6 can be moved, thereby causing the second mounting plate 6 and the third mounting plate 7 to slide on the hose 2, which in turn drives the fixing frame 8 and the slide bar 12 to slide on the truss 9. After sliding to the appropriate position, the third mounting plate 7 and the second mounting plate 6 are locked at a certain point on the hose 2 by the locking structure, thereby enabling the user's grip position to be adjusted.

[0030] See attached document Figure 3 The locking structure includes a threaded rod 13 threadedly connected to the bottom of the fixing frame 8, and a plurality of threaded grooves 15 adapted to the threaded rod 13 are provided in the truss 9, and the threaded rod 13 is inserted into one of the threaded grooves 15 and threadedly connected to the threaded groove 15.

[0031] When locking the third mounting piece 7, align the threaded rod 13 with the threaded groove 15 closest to it. Through the threaded connection between the threaded rod 13 and the threaded groove 15, the threaded rod 13 can be screwed into the threaded groove 15, thereby fixing the bracket 8 to a certain point on the truss 9. This restricts the movement of the third mounting piece 7 and the second mounting piece 6, thus completing the adjustment of the user's grip position. (Refer to the attached document.) Figure 2 and attached Figure 3 A second grip 11 is fixed at the bottom of the truss 9 and below the first mounting plate 5, and a first grip 10 is fixed at the bottom of the threaded rod 13. Both the first grip 10 and the second grip 11 have anti-slip textures on their outer sides to prevent the user's hand from slipping when holding them. The first grip 10 allows the user to easily hold the second mounting plate 6 and the third mounting plate 7, and the second grip 11 allows the user to hold the second grip 11 as needed. According to the above structure, a first spring 14 is installed between the first grip 10 and the fixing frame 8 and on the outer side of the threaded rod 13. The first spring 14 ensures the fit between the threaded rod 13 and the inner wall of the threaded groove 15, thereby increasing the torque and ensuring that the threaded rod 13 avoids rotation as much as possible without human intervention.

[0032] See attached document Figure 4 The top of the truss 9 is provided with a sliding groove 17, and the sliding groove 17 is connected to multiple threaded grooves 15. The top of the threaded rod 13 is fixed with an abutment strip 16, and the abutment strip 16 is inserted into the sliding groove 17. The inner wall of the third mounting plate 7 is slidably connected with an abutment plate 19. The bottom of the abutment plate 19 is fixed with a sliding strip 18, and the sliding strip 18 passes through the third mounting plate 7 and extends into the sliding groove 17. When the abutment strip 16 moves upward, it can abut against the sliding strip 18, thereby causing the abutment plate 19 to move upward.

[0033] When the threaded rod 13 is turned, it can drive the abutment strip 16 to move upward until the abutment strip 16 and the sliding strip 18 abut against each other. This causes the sliding strip 18 to drive the abutment piece 19 to move upward, thereby increasing the fit of the hose 2 and ensuring the stability of the first grip 10. The sliding groove 17 allows the sliding strip 18 to slide within the groove 17 without being obstructed when it slides with the fixed frame 8. A reset structure is installed between the truss 9 and the sliding strip 18. The reset structure includes a sliding piece 22 slidably connected to the top of the truss 9. The sliding strip 18 is slidably connected up and down. A fixing plate 20 is fixed on the outer side of the sliding strip 18 and on the top of the sliding plate 22. A second spring 21 is installed between the fixing plate 20 and the sliding plate 22 and on the outer side of the sliding strip 18. When the threaded rod 13 is turned in the opposite direction, the abutment strip 16 gradually stops contacting the sliding strip 18. Then, through the setting of the second spring 21, the second spring 21 can drive the sliding strip 18 to move down, so that the abutment plate 19 stops contacting the hose 2. In this way, when the second mounting plate 6 and the third mounting plate 7 are moved, the corresponding friction is reduced.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
