Description

Technical Field

[0002] An underwater high-pressure nozzle refers to a nozzle device that can generate high-pressure water flow in an underwater environment and is mainly used for operations such as cleaning, cutting, and crushing. The working principle of an underwater high-pressure nozzle is mainly to convert the pressure energy of high-pressure water into kinetic energy by shrinking the cross-section of the inner hole of the nozzle, and finally eject it from the nozzle in the form of a high-speed water jet. This high-speed water jet has strong impact force and cutting force, and can effectively remove dirt, rust, paint and other attachments on the surface of underwater objects.

[0003] During the production of an underwater high-pressure nozzle, it is necessary to detect the impact force. In related technologies, devices such as flow meters and pressure sensors are used to monitor the response of the nozzle, including whether there is water leakage, deformation, detachment, etc. And during the test process, the pressure value can be gradually adjusted to observe the impact force performance of the nozzle under different pressures. The nozzle is usually fixedly installed. When the nozzle is damaged, it is inconvenient to carry out maintenance, and the nozzle cannot be replaced, and the device can only be scrapped.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0027] An underwater impact force detection device for an underwater high-pressure nozzle, comprising:

[0028] A detection glass cylinder 1, with a water cylinder 2 arranged on one side of the detection glass cylinder 1;

[0029] The nozzle body 3 has a support member 4 fixedly installed at its lower end. A connecting block 5 is fixedly welded to the support member 4. At the lower end of the inner cavity of the detection glass cylinder 1, a support column 6 is fixedly installed. A connecting groove 7 for engaging the connecting block 5 is provided at the upper end of the support column 6. Both sides of the connecting block 5 are connected to the connecting groove 7 through a clamping assembly. The clamping assembly includes a return spring 8 and a clamping block 9. The return spring 8 is installed in an installation groove 10 provided on one side of the connecting block 5. Clamping grooves 11 for the clamping block 9 to penetrate the extension section of the installation groove 10 and engage are provided on both sides of the connecting groove 7.

[0030] When installing the nozzle body 3 at the upper end of the support column 6, press the clamping block 9 to engage the connecting block 5 in the connecting groove 7. The return spring 8 releases its elastic potential energy and pushes the clamping block 9 to engage in the clamping groove 11, quickly connecting the nozzle body 3 and the support column 6 and increasing the installation connection rate. When disassembling the nozzle body 3, press the clamping block 9 and take out the connecting block 5 from the connecting groove 7.

[0031] Furthermore, a water delivery component is connected between the water tank 2 and the nozzle body 3. The water delivery component includes a high-pressure water pump 20, a connecting pipe 21, and a water delivery pipe 22. The high-pressure water pump 20 is fixedly installed on one side of the detection glass cylinder 1. The high-pressure water pump 20 is connected to the nozzle body 3 through the connecting pipe 21. The other end of the high-pressure water pump 20 is connected to the water delivery pipe 22, and the other end of the water delivery pipe 22 is connected to the water tank 2.

[0032] When delivering water into the nozzle body 3, the high-pressure water pump 20 delivers the water in the water tank 2 into the nozzle body 3 through the connecting pipe 21 and the water delivery pipe 22, facilitating the nozzle body 3 to spray water for impact force detection.

[0033] A detection component, which is installed at the lower end of the inner cavity of the detection glass cylinder 1 through a moving mechanism.

[0034] Specifically, the detection component includes a support plate 17, a detection plate 18, and a pressure sensor 19. The support plate 17 is fixedly installed at the upper end of the moving block 15. The pressure sensor 19 is fixedly installed between the support plate 17 and the detection plate 18. The nozzle body 3 corresponds to the center of the detection plate 18. The moving mechanism includes a moving plate 12, a servo motor 13, a threaded rod 14, and a moving block 15. The moving plate 12 is fixedly installed at the lower end of the inner cavity of the detection glass cylinder 1. A moving groove 16 for the threaded rod 14 to be rotatably connected is provided on the moving plate 12. The moving block 15 is connected to the threaded rod 14. The servo motor 13 is fixedly installed at one end of the moving plate 12, and the output end of the servo motor 13 is connected to the extension section of the threaded rod 14 passing through the moving plate 12.

[0035] When detecting the nozzle body 3, the nozzle body 3 sprays water onto the detection plate 18, and the pressure sensor 19 detects the impact force. Through the setting of the servo motor 13, the moving block 15 can be driven to move by the threaded rod 14. The moving block 15 drives the support plate 17 to move, so as to drive the distance adjustment between the detection plate 18 and the pressure sensor and the nozzle body 3, thereby improving the detection effect of the nozzle body 3.

[0036] On the basis of the above embodiment, a controller 23 is installed on the detection glass cylinder 1. The controller 23 is electrically connected to the servo motor 13 and the high-pressure water pump 20, and the controller 23 is convenient for observing and controlling the detection of the nozzle body 3.

[0037] A waterproof cover 24 is installed at the lower end of the inner cavity of the detection glass cylinder 1, and the servo motor 13 is installed in the waterproof cover 24. The waterproof cover 24 can protect the servo motor 13 to prevent the servo motor 13 from being damaged by water and affecting the operation of the servo motor 13.

[0038] Drain pipes 25 are installed on one side of both the detection glass cylinder 1 and the water tank 2, and control valves 26 are installed on the drain pipes 25.

[0039] Through the setting of the control valve 26, the water in the detection glass cylinder 1 and the water tank 2 can be discharged through the drain pipe 25.

[0040] The working principle of this application is as follows:

[0041] First, install and fix the nozzle body 3. Press the clamping block 9 to clamp the connecting block 5 in the connecting groove 7. The return spring 8 releases elastic potential energy and pushes the clamping block 9 to be clamped in the clamping groove 11, quickly connecting the nozzle body 3 with the support column 6;

[0042] Then, inject water into the detection glass cylinder 1 and the water tank 2;

[0043] Then, the high-pressure water pump 20 transports the water in the water tank 2 to the nozzle body 3 through the connecting pipe 21 and the water delivery pipe 22. The nozzle body 3 sprays the water onto the detection plate 18, and the pressure sensor 19 detects the impact force. The controller 23 can observe the detection data;

[0044] When it is necessary to adjust the distance between the detection plate 18 and the nozzle body 3 for detection during detection, the servo motor 13 drives the moving block 15 to move through the threaded rod 14. The moving block 15 drives the support plate 17 to move, so as to drive the distance adjustment between the detection plate 18 and the pressure sensor and the nozzle body 3, improving the detection effect of the device.

[0045] It should be noted that the specific model specifications of the pressure sensor 19, the high-pressure water pump 20, and the controller 23 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
