[0017] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0018] This application mainly adopts a combination of a mobile module, a jet module, and a water supply module, which achieves the effect of flexible movement and efficient operation of the shaving machine. The following is a further detailed description of this application.

[0019] Example 1 The detachable high-pressure water jet shaving machine provided in this application includes a moving module 1, a jet module 2, and a water supply module 3. The moving module 1, jet module 2, and water supply module 3 are arranged in sequence. The jet module 2 is installed on the moving module 1, and the water supply module 3 is installed on the jet module 2. This achieves the effect of making the shaving machine flexible and efficient in shaving operations. This is because the moving module 1 can drive the entire shaving machine to move flexibly, and the water supply module 3 provides high-pressure water to the jet module 2. The jet module 2 uses the high-pressure water to perform shaving operations. The three work together to achieve the unity of flexible movement and efficient operation.

[0020] Specifically, the mobile module 1 includes a base 4, a mounting groove 5 at the top of the base 4, a moving wheel 6 at the bottom of the base 4, and a moving motor 7 inside the base 4, which is electrically connected to the moving wheel 6.

[0021] The base 4 is typically made of a sturdy metal material, such as steel, to ensure it can withstand the weight of the jet module 2 and the water supply module 3. The mounting slot 5 is a recessed groove at the top of the base 4 for mounting the jet module 2; its shape and size are adapted to the mounting base 8 of the jet module 2. The casters 6 can be omnidirectional casters, facilitating the movement of the shaving machine in all directions. They are connected to the base 4 via a shaft and can rotate flexibly. The moving motor 7 is generally a DC motor, installed inside the base 4 and connected to the casters 6 via wires. When the moving motor 7 is powered on, it drives the casters 6 to rotate, thus moving the shaving machine. Alternatively, the moving motor 7 can be replaced with a stepper motor, which can more precisely control the rotation angle and speed of the casters 6.

[0022] The electric connection between the mobile motor 7 and the mobile wheel 6 is achieved by connecting the motor's output terminal to the drive device of the mobile wheel 6 via a wire. When the motor runs, its power is transmitted to the drive device of the mobile wheel 6 through an electrical signal, causing the mobile wheel 6 to rotate. The mobile module 1 drives the mobile wheel 6 to rotate through the mobile motor 7, realizing the flexible movement of the shaving machine, facilitating operation in different construction sites, and improving the flexibility of the shaving machine.

[0023] Specifically, the mounting slot 5 is equipped with a jet module 2, which includes a mounting base 8, a high-pressure water gun 9, a placement slot 10 on the top of the mounting base 8, a through first water pipe hole 11 on the top of the mounting base 8, and a first high-pressure water pipe 12 connected to the high-pressure water gun 9 in the first water pipe hole 11.

[0024] Mounting base 8 is generally made of aluminum alloy, a lightweight material with a certain degree of strength. Mounting base 8 has mounting holes for mounting the high-pressure water gun 9, which is then fixed to the mounting base 8 with bolts. The high-pressure water gun 9 is a key component of the roughening machine, capable of spraying high-pressure water at high speed to impact the surface of the object for roughening. Placement slot 10 is a recessed groove in the top of mounting base 8 for placing the water supply module 3. The first water pipe hole 11 is a hole penetrating the top of mounting base 8, allowing the first high-pressure water pipe 12 to pass through. The first high-pressure water pipe 12 is typically made of high-strength rubber tubing; one end connects to the high-pressure water gun 9, and the other end connects to the second high-pressure water pipe 19 of the water supply module 3. The first high-pressure water pipe 12 can also be replaced with a stainless steel pipe, which has better corrosion resistance.

[0025] The first high-pressure water pipe 12 is connected to the high-pressure water gun 9 through a sealed joint to ensure that there is no water leakage at the connection. The jet module 2 sprays high-pressure water out through the high-pressure water gun 9 to realize the function of roughening. The high-pressure water gun 9 is installed on the mounting base 8 for easy fixation and operation.

[0026] Specifically, a water supply module 3 is installed inside the placement tank 10. The water supply module 3 includes a placement base 13, and a water inlet pipe 14 extending to the outside is installed inside the placement base 13. The other end of the water inlet pipe 14 is connected to a low-pressure water pump 15. The low-pressure water pump 15 is connected to a high-pressure water pump 17 through a connecting water pipe 16. A second water pipe hole 18 is provided through the bottom of the placement base 13. The second water pipe hole 18 and the first water pipe hole 11 are configured to cooperate. The high-pressure water pump 17 is connected to the first high-pressure water pipe 12 through a second high-pressure water pipe 19. A guide groove 33 is provided on the placement tank 10, and a slider 34 is provided on the placement base 13. The slider 34 is configured to cooperate with the guide groove 33. An electrical control box 35 is installed inside the placement base 13. The electrical control box 35 is electrically connected to the low-pressure water pump 15 and the high-pressure water pump 17 respectively. A second controller 36 is provided on the side surface of the placement base 13. The second controller 36 is electrically connected to the electrical control box 35, the first motor 20 and the second motor 21.

[0027] The placement base 13 is generally made of plastic, which is lightweight and low-cost. One end of the water inlet pipe 14 extends to the outside of the placement base 13 to draw water from the water source; the water inlet pipe 14 is usually made of PVC. A low-pressure water pump 15 is installed inside the placement base 13. Its function is to draw water from the water source and deliver it to the high-pressure water pump 17 via the connecting water pipe 16. The connecting water pipe 16 can be a rubber hose, connecting the low-pressure water pump 15 and the high-pressure water pump 17. The high-pressure water pump 17 is the core component of the water supply module 3; it can pressurize low-pressure water into high-pressure water. The high-pressure water pump 17 is generally a multi-stage centrifugal pump. The second water pipe hole 18 is a hole penetrating the bottom of the placement base 13, corresponding to the position of the first water pipe hole 11 at the top of the mounting base 8, facilitating the passage of the second high-pressure water pipe 19 and its connection to the first high-pressure water pipe 12. The second high-pressure water pipe 19 is also made of high-strength rubber hose, connecting the outlet of the high-pressure water pump 17 to the first high-pressure water pipe 12. The low-pressure water pump 15 and high-pressure water pump 17 here can also be replaced with other types of water pumps, such as vortex pumps.

[0028] The second high-pressure water pipe 19 is also connected to the first high-pressure water pipe 12 through a sealed joint to ensure that the high-pressure water can be delivered smoothly. The water supply module 3, through the cooperation of the low-pressure water pump 15 and the high-pressure water pump 17, pressurizes the water into high-pressure water and delivers it to the high-pressure water gun 9, providing a power source for the scabbing operation.

[0029] Specifically, the low-pressure water pump 15 is electrically connected to a first motor 20, and the high-pressure water pump 17 is electrically connected to a second motor 21. The first motor 20 and the second motor 21 are generally AC motors, providing power to the low-pressure water pump 15 and the high-pressure water pump 17, respectively. The first motor 20 is connected to the low-pressure water pump 15 via a coupling. When the first motor 20 is energized and running, it drives the low-pressure water pump 15 to rotate, drawing water in. The second motor 21 is also connected to the high-pressure water pump 17 via a coupling, driving the high-pressure water pump 17 to pressurize the water. Alternatively, the first motor 20 and the second motor 21 can be replaced with permanent magnet synchronous motors, which offer higher efficiency and better speed regulation performance.

[0030] The placement slot 10 is provided with a guide slot 33, and the placement seat 13 is provided with a slider 34. The slider 34 is configured to cooperate with the guide slot 33. By placing the slider 34 into the guide slot 33, the placement seat 13 can be accurately positioned, and the stability of the placement seat 13 can also be increased. The placement seat 13 is provided with an electrical control box 35, which is electrically connected to the low-pressure water pump 15 and the high-pressure water pump 17 respectively. The electrical control box 35 can regulate the pressure of the low-pressure water pump 15 and the high-pressure water pump 17. The side surface of the placement seat 13 is provided with a second controller 36, which is electrically connected to the electrical control box 35, the first motor 20 and the second motor 21. The second controller 36 controls the start-up and water supply of the entire water supply process.

[0031] The implementation principle of this embodiment is as follows: The detachable high-pressure water jet shaving machine of this embodiment achieves a combination of flexible movement and efficient operation through the combination of the moving module 1, the jet module 2, and the water supply module 3. The moving motor 7 of the moving module 1 drives the moving wheels 6 to rotate, enabling the shaving machine to move flexibly to different construction positions. Driven by the first motor 20 and the second motor 21, the low-pressure water pump 15 and the high-pressure water pump 17 of the water supply module 3 pressurize the water into high-pressure water and deliver it to the high-pressure water gun 9 of the jet module 2. The high-pressure water gun 9 of the jet module 2 sprays the high-pressure water out to shaving the surface of the object. Compared with the traditional shaving method, this shaving machine avoids the low efficiency and unstable quality problems of manual shaving, and also solves the defects of pneumatic shaving machines such as high noise, strong vibration, and inconvenience of movement. It improves construction efficiency, reduces labor intensity, ensures the consistency and accuracy of shaving effect, and also reduces interference with the surrounding environment.

[0032] Example 2 The difference between this embodiment and the above embodiment is that: a push rod 22 is provided on the top of the side of the base 4 where the mounting groove 5 is not provided, and a first controller 23 electrically connected to the moving motor 7 is provided on the push rod 22.

[0033] The push rod 22 is generally made of steel pipe and welded to the base 4, making it convenient for the operator to push the chiseling machine. The first controller 23 can be a push-button controller, which is connected to the moving motor 7 via wires. The operator can control the start, stop, and speed of the moving motor 7 by operating the first controller 23, thereby controlling the movement of the chiseling machine. The first controller 23 can also be replaced with a touch screen controller, which is more convenient and intuitive to operate.

[0034] The implementation principle of this embodiment is as follows: Based on the above embodiment, this embodiment adds a push rod 22 and a first controller 23. The operator can push the chiseling machine to move through the push rod 22, and at the same time, the first controller 23 precisely controls the operation of the moving motor 7, making the movement of the chiseling machine more flexible and convenient, further improving the operation performance of the chiseling machine, and meeting the needs of chiseling machine movement control in different construction scenarios.

[0035] Example 3 The difference between this embodiment and the above embodiment is that: the side wall of the base 4 where the moving motor 7 is located is provided with heat dissipation holes 24, and the side wall of the placement seat 13 is provided with heat dissipation holes 24.

[0036] The heat dissipation holes 24 are generally small, round or square holes, evenly distributed on the side walls of the base 4 and the mounting base 13. The heat dissipation holes on the base 4 allow the heat generated by the moving motor 7 to dissipate, preventing damage from overheating. The heat dissipation holes on the mounting base 13 allow the heat generated by the low-pressure water pump 15, the high-pressure water pump 17, and the first motor 20 and the second motor 21 to dissipate, ensuring the normal operation of the equipment. The heat dissipation holes 24 can also be designed as louvers; louvered heat dissipation holes not only dissipate heat but also prevent dust and debris from entering the equipment.

[0037] The implementation principle of this embodiment is as follows: In this embodiment, heat dissipation holes 24 are provided on the base 4 and the placement seat 13, which effectively solves the problem of heat dissipation generated during the operation of the equipment, ensures the normal operation of the mobile motor 7, low-pressure water pump 15, high-pressure water pump 17, as well as the first motor 20 and the second motor 21, extends the service life of the equipment, and improves the stability and reliability of the equipment.

[0038] Example 4 The difference between this embodiment and the above embodiment is that: a fixing mechanism 25 is provided at the top of both sides of the mounting groove 5. The fixing mechanism 25 includes a fixing plate 26 fixed on both sides of the mounting groove 5. A connecting threaded hole 27 is provided on the fixing plate 26. A threaded rod 28 is provided inside the connecting threaded hole 27. A connecting block 29 is provided on the threaded rod 28 facing the top of the mounting groove 5.

[0039] The fixing plate 26 is generally made of metal plate and is fixed to both sides of the mounting groove 5 by welding or bolting. The threaded hole 27 is a threaded hole opened in the fixing plate 26. The threaded rod 28 mates with the threaded hole 27, and can move back and forth within the threaded hole 27 by rotating the threaded rod 28. The connecting block 29 is generally made of rubber and is installed at the top of the threaded rod 28 facing the mounting groove 5. When the threaded rod 28 is rotated to make the connecting block 29 contact the mounting seat 8, the mounting seat 8 can be fixed within the mounting groove 5. The connecting block 29 can also be replaced with a plastic block, which has better wear resistance.

[0040] The implementation principle of this embodiment is as follows: In this embodiment, a fixing mechanism 25 is set on both sides of the mounting groove 5. By rotating the threaded rod 28, the connecting block 29 is made to contact the mounting seat 8, and the mounting seat 8 of the jet module 5 is fixed in the mounting groove 5 of the moving module 1. This prevents the mounting seat 8 from shaking or shifting during the movement or operation of the shaving machine, ensuring the stability and reliability of the equipment and improving the accuracy of the shaving operation.

[0041] Example 5 The difference between this embodiment and the above embodiment is that: a filter 30 connected to the first high-pressure water pipe 12 is provided between the first water pipe hole 11 and the high-pressure water gun 9 inside the mounting base 8; a storage box 31 is provided on the side of the mounting base 8 opposite to the high-pressure water gun 9, and a box door 32 is provided on the side wall of the mounting base 8 on the side of the storage box 31; the high-pressure water gun 9 is a switchable multi-functional high-pressure water gun, and the high-pressure water gun 9 adopts a magnetic quick-change nozzle holder.

[0042] The filter 30 is generally a mesh filter, installed inside the mounting base 8, between the first water pipe hole 11 and the high-pressure water gun 9. The mesh filter removes impurities from the water, preventing them from entering the high-pressure water gun 9 and damaging its nozzle or affecting the spray effect. Alternatively, the filter 30 can be replaced with an activated carbon filter, which not only filters impurities but also adsorbs odors and harmful substances from the water. The storage box 31 can be used to store replacement high-pressure water gun 9 nozzles or other repair tools. The high-pressure water gun 9 uses a magnetic quick-change nozzle holder, allowing for rapid nozzle switching according to different usage scenarios.

[0043] The implementation principle of this embodiment is as follows: In this embodiment, a filter 30 is set between the first water pipe hole 11 and the high-pressure water gun 9, which effectively filters impurities in the water, protects the nozzle of the high-pressure water gun 9, improves the service life and spraying effect of the high-pressure water gun 9, and ensures the quality of the chiseling operation; the storage box 31 can store the tools that need to be used, and the setting of the high-pressure water gun 9 can be applied to different scenarios, improving work efficiency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
