Description

Technical Field

[0001] The present invention relates to the technical field of jet nozzles, and particularly to an efficient underwater cavitation jet nozzle. Background Technique

[0002] For large and ultra-large ocean engineering equipment, such as oil platforms, large floating structures, and submarine pipelines, in order to ensure their long-term normal operation, it is necessary to timely remove the attachments or corrosives on their surfaces. The current cleaning methods and efficiency are not ideal, and there are certain difficulties in realizing the cleaning of objects in deep water environments.

[0003] Chinese Patent with Publication (Announcement) No. CN206868490U discloses a cavitation jet nozzle device in a slender round tube, including a first component and a second component in a tubular structure. One end of the first component is provided with a water inlet connected to an external water pump water pipe, and the other end is provided with an internal thread stop. A first-stage cavitation chamber is arranged in the middle of the first component. One side of the first-stage cavitation chamber is communicated with the water inlet, and a short hole is arranged at the connection between the other side of the first-stage cavitation chamber and the internal thread stop. A plurality of air inlets communicated with the first-stage cavitation chamber are annularly arranged on the outer wall of the first component. The second component internally has a second-stage cavitation chamber with one end open, and an external thread stop capable of being screwed with the internal thread stop on the first component is arranged at the open end. A sealing ring is arranged at the connection between the internal thread stop and the external thread stop. A plurality of nozzles communicated with the second-stage cavitation chamber are annularly arranged on the outer wall of the second component.

[0004] The above patent has the following problems: When the cavitation jet nozzle is connected to external equipment, it is usually installed by means of threads. During the long-term use of the cavitation jet nozzle, due to the possible loosening of the thread installation, when the cavitation jet nozzle becomes loose, leakage will occur, affecting the effect during the use of the cavitation jet nozzle. Moreover, the frequent disassembly of the thread installation method will also cause thread damage, which is not conducive to the disassembly and replacement of the cavitation jet nozzle. In view of this, we propose an efficient underwater cavitation jet nozzle. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient underwater cavitation jet nozzle to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: An efficient underwater cavitating jet nozzle, comprising: a cavitating jet nozzle, on one side of which is fixedly installed a mounting pipe, an external connecting pipe is sleeved on the mounting pipe, mounting grooves are formed on both sides of the external connecting pipe, and clamping grooves are provided on both of the two mounting grooves; two clamping blocks, which are respectively fixedly installed on both sides of the mounting pipe, the two clamping blocks are slidably matched with the mounting grooves, the two clamping blocks are respectively arranged in the two clamping grooves, and one side of each of the two clamping blocks abuts against one side of the inside of each of the two clamping grooves; a movable ring, which is slidably connected to the mounting pipe, and one side of the movable ring abuts against one end of the external connecting pipe; a limiting component, which is arranged on the movable ring and is used for limiting the movable ring.

[0007] Preferably, the limiting component includes a second limiting hole formed on one side of the movable ring, a first limiting hole is formed on one side of the mounting pipe, and the same inserting rod is movably sleeved in the first limiting hole and the second limiting hole.

[0008] Preferably, a second limiting spring is sleeved on the inserting rod, one end of the second limiting spring is fixedly connected to the outer side wall of the movable ring, and the other end of the second limiting spring is fixedly connected to the inserting rod.

[0009] Preferably, a sealing ring is arranged on the outer side wall of the mounting pipe, and the outer side wall of the sealing ring is movably sleeved with the inner side wall of the external connecting pipe.

[0010] Preferably, a plurality of reset springs are fixedly installed on one side of the cavitating jet nozzle, and the other ends of the plurality of reset springs are fixedly connected to one side of the movable ring.

[0011] Preferably, the mounting grooves are L-shaped grooves, and the two mounting grooves are symmetrically arranged on both sides of the external connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are: For this efficient underwater cavitating jet nozzle, when disassembling the external connecting pipe and the cavitating jet nozzle, pull the inserting rod outwards. When it disengages from the first limiting hole, the limitation on the movable ring can be released. Push the external connecting pipe. When the external connecting pipe enters the mounting groove after disengaging from the clamping groove, at this time, rotate the external connecting pipe. When the clamping block moves to the opening of the mounting groove, the disassembly of the external connecting pipe and the cavitating jet nozzle can be completed. This disassembly method is simple to operate and convenient to disassemble.

[0013] When installing the cavitation jet nozzle and the external connecting pipe, align the clamping block with the installation groove, and sleeve the external connecting pipe on the installation pipe. At this time, the clamping block enters the clamping groove through the installation groove. After the clamping block enters the clamping groove, the movable ring is pushed back by the return spring. At this time, the movable ring abuts against the external connecting pipe. After the movable ring abuts against the external connecting pipe, the clamping block abuts against the clamping groove, thus realizing the installation between the cavitation jet nozzle and the external connecting pipe. In order to enhance the fixation when installing the cavitation jet nozzle and the external connecting pipe, the insertion rod is sleeved in the first limiting hole to limit the movable ring. After the movable ring is limited, since the movable ring abuts against the external connecting pipe, the external connecting pipe will also be limited at this time, thereby enhancing the fixation and stability when installing the cavitation jet nozzle and the external connecting pipe, which is relatively practical.

The insertion rod 11 is sleeved in the first limiting hole 9 to limit the movable ring 7. When the movable ring 7 is limited, since the movable ring 7 abuts against the external connection pipe 3, at this time, the external connection pipe 3 will also be limited, thereby enhancing the fixing and stability when the cavitation jet nozzle 1 and the external connection pipe 3 are installed.
