Description

Technical Field

[0001] The present invention relates to the technical field of transmission line connection, and particularly relates to a precision waterproof connector. Background Art

[0002] An ocean ship meteorological observation station is a key device for modern navigation safety and meteorological data collection. Devices such as wind speed and direction sensors and temperature and humidity monitors are usually installed at the highest point of the hull to obtain accurate data. These systems are inevitably exposed to the harshest marine environment, directly facing multiple challenges such as seawater scouring and continuous salt spray erosion; it is necessary to regularly clean the equipment and connectors. Since the above-mentioned equipment is usually located on the mast on top of the cab, in order to reduce the climbing up and down of the staff, a high-pressure water gun is usually used for flushing.

[0003] A Chinese patent document (Publication No.: CN119340725B) discloses a tensile waterproof and explosion-proof cable connector, which particularly relates to the technical field of cable connection. It includes a fixing sleeve, and one end of a clamping rod is slidably sleeved on the end face of the fixing sleeve. The advantages of the present invention are as follows: it can automatically fasten the inner conductor, so that the inner conductor does not need to be clamped off, does not need to be connected and compacted with a copper tube, does not need to be sealed with a heat-shrinkable sleeve, and does not need to be integrally fastened with a heat-shrinkable tube. This not only simplifies the operation steps, reduces the labor intensity, shortens the cable connection time, but also reduces the requirements for operators, reduces the labor cost. Moreover, while the cable connector is anti-tensile, the cable and the cable connector are completely sealed, so that the cable connector achieves the purpose of waterproofing and explosion-proofing, and the cable after being connected by the cable connector can be applied to extreme environments, expanding the application range of the cable connector, and the anti-tensile and waterproof and explosion-proof functions can work together, that is, the greater the pulling strength, the less likely there are gaps between the cable and the cable connector, thus fully ensuring the waterproof and explosion-proof effect.

[0004] Connectors such as wind speed and direction sensors or temperature and humidity monitors are usually installed at the highest point of the hull. During the process of flushing with a high-pressure water gun, the operator needs to continuously adjust the position of the water gun impact, and has to hold the water gun and adjust the standing position on the deck. The operation is cumbersome and there are safety hazards in working at height; when using a high-pressure water gun to clean the connector, the random impact of the high-pressure water gun nozzle will cause the connector to shake or bend at the docking place, affecting the connection strength and sealing performance, and making the use of the equipment have greater safety hazards. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a precision waterproof connector. During the process of being flushed with a high-pressure water gun, the connector does not require the operator to adjust the standing position, and the high-pressure water gun will not cause shaking or bending at the connection part of the connector, ensuring the normal operation of the device and extending its service life.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A precision waterproof connector includes docking heads installed at the ends of two transmission lines. Adaptive tension adjustment components are provided on both transmission lines. The adaptive tension adjustment component includes a fixed sleeve located on the outer peripheral surface of the transmission line adjacent to the docking head. A sleeve shaft is rotatably provided on the fixed sleeve. A rotating cylinder is provided on the outer periphery of the sleeve shaft. A plurality of guide vanes are arranged in an array along the center of the outer peripheral surface of the rotating cylinder. An annular chamber is formed at an interval between the inner wall of the rotating cylinder and the outer wall of the sleeve shaft. A buffer reset unit is arranged inside the annular chamber, and the buffer reset unit connects the outer wall of the sleeve shaft and the inner wall of the rotating cylinder. A tensioning unit is also arranged inside the annular chamber. The tensioning unit extends to the outside of the rotating cylinder and a tension disk is fixedly arranged at the end. The tension disks on two groups of adaptive tension adjustment components are connected through a split shaft sleeve.

[0007] Preferably, the buffer reset unit includes a convex rod axially arranged on one side of the sleeve shaft. A convex shoulder is fixedly arranged on the outer periphery of the sleeve shaft at the end far from the docking head. One end of the convex rod is fixedly connected to the convex shoulder, and the other end of the convex rod is fixedly connected to the sleeve shaft through a convex block.

The traction block is fixedly installed on the rotating cylinder. An elastic member is fixedly arranged on one side of the convex rod, and the other end of the elastic member is fixedly connected to the adjacent slide rod.

[0008] Preferably, the tensioning unit includes a lifting ring body sleeved on the outer periphery of the sleeve shaft. A guide groove is formed on the outer peripheral surface of the sleeve shaft. The guide groove extends to both sides and gradually moves away from the docking head to form a V-shaped groove. A guide rod is arranged on the lifting ring body, and the guide rod extends into the guide groove. A dovetail groove is formed on the outer peripheral surface of the lifting ring body. A dovetail plate is slidably arranged in the dovetail groove. A telescopic plate is fixedly arranged on the dovetail plate in the direction towards the docking head. The telescopic plate slidably penetrates through the second end cover of the rotating cylinder. The end of the telescopic plate is fixedly connected to the tension disk, and the tension disk is slidably sleeved on the fixed sleeve.

[0009] Preferably, the split shaft sleeve includes two half shaft sleeves. Chute grooves are correspondingly formed in the two half shaft sleeves for the two tension disks. Half ring pieces are arranged on the side walls along the axis in the chute grooves. The two half ring pieces are both connected to the inner wall of the chute groove through reset elastic members. Mounting holes are respectively formed on the two split shaft sleeves.

[0010] Preferably, a mounting groove is formed on one side of the dovetail groove of the lifting ring body, and a cover is arranged on the mounting groove. A connection hole is formed on the side of the traction block close to the rotating cylinder. A through hole is formed on the rotating cylinder corresponding to the connection hole. A connecting rod is installed outside the rotating cylinder. The connecting rod passes through the through hole and then extends into the connection hole to fixedly connect the rotating cylinder, the traction block and the lifting ring body.

[0011] Preferably, the docking head includes a telecommunication integrated joint installed at the ends of two transmission lines. The telecommunication integrated joint has two ports, namely a plug and a socket. The two ports are respectively installed at both ends of the two transmission lines. An annular threaded head is integrally formed on the outer periphery of the plug. A nut is movably sleeved outside the socket. The nut is matched and connected with the threaded head for sealing. A sealing ring is arranged on the inner wall at the other end of the nut.

[0012] Preferably, first end caps and second end caps are respectively arranged at both ends of the rotating cylinder. Angular contact ball bearings are arranged between the first end cap, the second end cap and the sleeve shaft.

[0013] Preferably, the elastic member is an arc-shaped spring. The arc-shaped spring is arranged along the arc of the annular chamber, is made of stainless steel, and has corrosion resistance and a stable restoring force.

[0014] Preferably, the number of the guide vanes is 6 - 8, which are evenly distributed along the circumference, and the surface thereof is arc-shaped.

[0015] Preferably, mounting seats are fixedly connected to the ends of the fixed sleeves far away from the docking heads.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The connector of the present invention is provided with a buffer and reset unit. During the process of the connector being washed by a high-pressure water gun, the guide vanes drive the rotating cylinder to rotate together under the impact of water pressure. When the rotating cylinder rotates, under the action of the buffer and reset unit, it can not only disperse the high pressure of the water gun washing, but also enable the rotating cylinder to rotate for self-cleaning, avoiding the connector from bearing excessive stamping resulting in the loosening or even damage of the connection due to shaking. During the rotation of the rotating cylinder, different parts are washed by the water flow, avoiding the operator from deliberately adjusting the position of the water gun for alignment cleaning. Specifically, a rotating cylinder is arranged on the outer periphery of the connector. Guide vanes are evenly distributed on the surface of the rotating cylinder. The sleeve shaft is sleeved on the fixed sleeve, and the rotating cylinder is sleeved outside the sleeve shaft. There is an annular chamber between the inner wall of the rotating cylinder and the outer wall of the sleeve shaft. An elastic member and two parallel sliding rods are arranged inside the annular chamber. An elastic member is installed between the convex rod outside the sleeve shaft and the adjacent sliding rod. A traction block arranged between the two sliding rods is fixedly connected to the inner wall of the rotating cylinder. When the rotating cylinder rotates under the cooperation of water pressure and the guide vanes, the rotating cylinder drives the traction block to rotate. The traction block first squeezes the corresponding sliding rod and compresses the adjacent elastic member, and then drives the sleeve shaft to rotate together. During this process, when the rotating cylinder and the guide vanes are impacted by water pressure and rotate, they will compress the elastic member and then rotate together with the sleeve shaft, buffering the impact of the high-pressure water gun and absorbing energy, avoiding the connector from bearing excessive impact force and affecting the structural stability and service life.

[0017] 2. In the present invention, the connector is provided with a tensioning unit. During the process of being rinsed by a high-pressure water gun, the guide vane drives the rotating cylinder to rotate together under the impact of water pressure. Under the action of the tensioning unit, no matter whether the rotating cylinder rotates clockwise or counterclockwise during rinsing, the rotating cylinder drives the lifting ring body to move axially away from the docking head, so that the two ends of the connector are further close and stable through the tension disks, avoiding the shaking of the threaded joint of the connector caused by the impact of the high-pressure water gun and resulting in connection loosening or even structural damage. Specifically, a guide rod is provided on the lifting ring body fixedly connected to the rotating cylinder. The lifting ring body is sleeved on the outer periphery of the sleeve shaft, and the guide rod is slidably installed in the guide groove. When the rotating cylinder is driven to rotate by water pressure, the lifting ring body and the guide rod rotate together, and the guide rod slides inside the guide groove on the outer periphery of the sleeve shaft. Since the guide groove is a V-shaped arc groove formed by the continuation of its two sides in the direction away from the docking head, no matter which direction the rotating cylinder rotates, it will drive the lifting ring body to move in the direction away from the docking head, thereby driving the telescopic plate and the tension disk to move together. Under the action of connecting the two tension disks by the split shaft sleeve, the displacement generated by the lifting ring body is finally converted into the acting force of pulling and pressing the two ends of the connector tightly, strengthening the two ends of the connector, ensuring the stable docking of the threaded joint of the connector without shaking, ensuring the normal operation of the equipment, and prolonging the service life of the connector.

[0018] 3. While connecting the tension disks at both ends, the split shaft sleeve of the tensioning unit of the present invention can also provide full-enclosure protection for the threaded joint of the connector, avoiding the direct contact of the connection part of the connector with the marine environment or being shot by the water gun, playing an isolation and protection role. Specifically, since the two tension disks are respectively located at both ends of the connection head, when the sliding groove of the split shaft sleeve is connected with the tension disk, the split shaft sleeve and the two tension disks enclose an independent chamber, and the threaded head connection part of the connector is located inside the independent chamber. The independent chamber isolates the threaded head connection part of the connector from the external marine air environment, and at the same time blocks the direct injection of the high-pressure water gun, playing an anti-corrosion or impact damage role, ensuring the normal operation of the equipment, and further ensuring the stability and service life of the connector.

[0022] Example:

[0023] Figures 1 - 7As shown in the figure, a precision waterproof connector includes docking heads installed at the ends of two transmission lines 11. Adaptive tension adjustment components are provided on both transmission lines 11. The adaptive tension adjustment component includes a fixing sleeve 12, which is arranged on the outer peripheral surface of the transmission line 11 adjacent to the docking head. A sleeve shaft 25 is rotatably arranged on the fixing sleeve 12. A rotating cylinder 14 is arranged on the outer periphery of the sleeve shaft 25. A plurality of guide vanes 15 are arranged in an array along the center of the outer periphery of the rotating cylinder 14. An annular chamber is formed at an interval between the inner wall of the rotating cylinder 14 and the outer wall of the sleeve shaft 25. A buffer reset unit is arranged inside the annular chamber, and the buffer reset unit connects the outer wall of the sleeve shaft 25 and the inner wall of the rotating cylinder 14. A tensioning unit is also arranged inside the annular chamber. The tensioning unit extends to the outside of the rotating cylinder 14 and a tension disk 19 is fixedly arranged at the end. The tension disks 19 on the two adaptive tension adjustment components are connected by a split shaft sleeve 16.

[0024] In the present invention, after the line ends of the connector are connected, the mounting seat 13 is fixed to the adjacent mast or equipment connecting plate. Figure 1 As shown in the figure, it is the state when the connector is installed. The cooperation between the mounting seat 13 and the fixing sleeve 12 adopts a fixed connection.

[0025] The fixing sleeve 12 is fixedly installed on the outer periphery of the transmission line 11 or can be integrally formed. The outer periphery of the fixing sleeve 12 has the function of fixing the axis and provides a rotational center support for other rotating components.

[0026] Further, the buffer reset unit includes a convex rod 31 arranged axially on one side of the sleeve shaft 25. A convex shoulder 32 is fixedly arranged on the outer periphery of the sleeve shaft 25 at the end far from the docking head. One end of the convex rod 31 is fixedly connected to the convex shoulder 32, and the other end of the convex rod 31 is fixedly connected to the sleeve shaft 25 through a convex block 33. Two sliding rods 26 are arranged along the axis on the side of the annular chamber far from the convex rod 31. A traction block 29 is arranged between the two sliding rods 26, and the traction block 29 is fixedly installed on the rotating cylinder 14. An elastic member 27 is fixedly arranged on one side of the convex rod 31, and the other end of the elastic member 27 is fixedly connected to the adjacent sliding rod 26.

[0027] See Figure 1 、 Figure 4 and Figure 5In this case, the connector of the present invention is provided with a buffer reset unit. During the process of being washed by a high-pressure water gun, the guide vane 15 drives the rotating cylinder 14 to rotate together under the impact of water pressure. When the rotating cylinder 14 rotates, under the action of the buffer reset unit, it can not only disperse the high pressure of the water gun washing, but also enable the rotating cylinder to rotate for self-cleaning, avoiding the connector from bearing excessive stamping, resulting in shaking, loosening or even damage at the connection. During the rotation of the rotating cylinder 14, different parts are washed by the water flow, avoiding the operator from deliberately adjusting the position of the water gun for alignment cleaning. Specifically, the rotating cylinder 14 is arranged on the outer periphery of the connector, the guide vanes 15 are evenly distributed on the surface of the rotating cylinder 14, the sleeve shaft 25 is sleeved on the fixed sleeve 12, the rotating cylinder 14 is sleeved outside the sleeve shaft 25, there is an annular chamber between the inner wall of the rotating cylinder 14 and the outer wall of the sleeve shaft 25, an elastic member 27 and two parallel sliding rods 26 are arranged inside the annular chamber, an elastic member 27 is installed between the convex rod 31 outside the sleeve shaft 25 and the adjacent sliding rod 26, and a traction block 29 arranged between the two sliding rods 26 is fixedly connected to the inner wall of the rotating cylinder 14; when the rotating cylinder 14 rotates under the cooperation of water pressure and the guide vane 15, the rotating cylinder 14 drives the traction block 29 to rotate. The traction block 29 first squeezes the corresponding sliding rod 26 and compresses the adjacent elastic member 27, and then drives the sleeve shaft 25 to rotate together; during this process, when the rotating cylinder 14 and the guide vane 15 are impacted by water pressure and rotate, they will compress the elastic member 27 and then rotate together with the sleeve shaft 25, buffering the impact of the high-pressure water gun and absorbing energy, avoiding the connector from bearing excessive impact force and affecting the structural stability and service life.

[0028] It should be noted that the shoulder 32 and the telescopic plate 18 have a certain supporting effect on the elastic member in the annular chamber, which is beneficial for it not to deviate from the main position during the deformation process.

[0029] Furthermore, the tensioning unit includes a lifting ring body 28, the lifting ring body 28 is sleeved on the outer periphery of the sleeve shaft 25, a guide groove 34 is opened on the outer peripheral surface of the sleeve shaft 25, and the guide groove 34 extends to both sides and gradually moves away from the docking head; a guide rod 35 is arranged on the lifting ring body 28, and the guide rod 35 extends into the guide groove 34; a dovetail groove 36 is opened on the outer peripheral surface of the lifting ring body 28, a dovetail plate 38 is slidably arranged in the dovetail groove 36, the dovetail plate 38 is fixedly provided with a telescopic plate 18 in the direction towards the docking head, the telescopic plate 18 slidably penetrates through the second end cover 24 of the rotating cylinder 14, and the end of the telescopic plate 18 is fixedly connected with a tension disc 19, and the tension disc 19 is slidably sleeved on the fixed sleeve 12.

[0030] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7, in the present invention, the connector is provided with a tensioning unit. During the process of being washed by a high-pressure water gun, the guide vane 15 drives the rotating cylinder 14 to rotate together under the impact of the water pressure. Under the action of the tensioning unit, no matter whether the rotating cylinder 14 rotates clockwise or counterclockwise during washing, the rotating cylinder 14 drives the lifting ring body 28 to move axially away from the docking head, so that the two ends of the connector are further close and stable through the tension disks, avoiding the impact of the high-pressure water gun causing shaking at the threaded joint of the connector and resulting in loosening or even damage to the structure; Specifically, a guide rod 35 is provided on the lifting ring body 28 fixedly connected to the rotating cylinder 14. The lifting ring body 28 is sleeved on the outer periphery of the sleeve shaft 25, and the guide rod 35 is slidably installed in the guide groove 34. When the rotating cylinder 14 is driven to rotate by the water pressure, the lifting ring body 28 and the guide rod 35 rotate together, and the guide rod 35 slides inside the guide groove 34 on the outer periphery of the sleeve shaft 25; Since the guide groove 34 is a V-shaped arc groove formed by extending the two sides away from the docking head, no matter which direction the rotating cylinder 14 rotates, it will drive the lifting ring body 28 to move away from the docking head, thereby driving the telescopic plate 18 and the tension disk 18 to move together. Under the action of connecting the two tension disks 18 by the split shaft sleeve 16, the displacement generated by the lifting ring body 28 is finally converted into a pulling and pressing force for the two ends of the connector, strengthening the two ends of the connector, ensuring stable docking without shaking at the threaded joint of the connector, ensuring the normal operation of the equipment, and prolonging the service life of the connector.

[0031] Furthermore, the split shaft sleeve 16 includes two groups of half shaft sleeves, and sliding grooves 20 are correspondingly formed in the half shaft sleeves for the two tension disks 19; a half ring piece (not shown in the figure) is provided on the side wall of the sliding groove 20 along the axis, and the half ring piece is connected to the inner wall of the sliding groove 20 through a reset elastic member (not shown in the figure); mounting holes are respectively formed in the two split shaft sleeves 16.

[0032] See Figure 2 , while connecting the tension disks 19 at both ends, the split shaft sleeve 16 of the tensioning unit of the present invention can also provide full-enclosure protection for the threaded joint of the connector, avoiding the direct contact of the connection part of the connector with the marine environment or being shot by the water gun, playing an isolation and protection role; Specifically, since the two tension disks 19 are respectively located at both ends of the connection head, when the sliding groove 20 of the split shaft sleeve 16 is connected with the tension disk 19, the split shaft sleeve 16 and the two tension disks 19 enclose an independent chamber, and the threaded head connection part of the connector is located inside the independent chamber; The independent chamber isolates the threaded head connection part of the connector from the external marine air environment, and also blocks the direct jet of the high-pressure water gun, playing an anti-corrosion or impact damage role, ensuring the normal operation of the equipment, and further guaranteeing the stability and service life of the connector.

[0033] It should be noted that the semi-circular piece is in abutting sliding contact with the tension disc 19, which is beneficial to the rotation of the tension disc 19. The reset elastic member is installed between the semi-circular piece and the tension disc 19. The reset elastic member can adapt to the tension changes under different working conditions and enhance the adaptability of the connector. During the high-pressure water gun flushing process, the reset elastic member can absorb part of the vibration and impact energy, further reducing the load at the threaded joint of the connector.

[0034] Among them, the semi-circular piece is correspondingly installed in the split bushing 16. After being combined, a complete circular piece is formed. The circular piece is arranged to slide axially in the chute 20. The reset elastic member can be a compression spring, a leaf spring or an elastic rubber pad.

[0035] Furthermore, an installation groove 39 is opened on one side of the dovetail groove 36 of the lifting ring body 28, and a cover 37 is arranged inside the installation groove 39; a connection hole 30 is arranged on one side of the traction block 29 close to the rotating cylinder 14. A through hole is opened on the rotating cylinder 14 corresponding to the connection hole 30. A connecting rod is installed outside the rotating cylinder 14. After passing through the through hole, the connecting rod extends into the connection hole 30 to fixedly connect the rotating cylinder 14, the traction block 29 and the lifting ring body 28.

[0036] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in, both the dovetail plate 38 and the dovetail groove 36 are arranged in an arc shape along the outer circumference of the lifting ring body 28. The dovetail plate 38 is slidably installed inside the dovetail groove 36. When the lifting ring body 28 rotates, the dovetail plate 38 and the telescopic plate 18 remain in a fixed position radially. The dovetail plate 38 slides in the dovetail groove 36 of the lifting ring body 28; when the lifting ring body 28 moves up and down, the dovetail plate 38 and the telescopic plate 18 move up and down together, thereby driving the up and down movement of the tension disc 19; among them, the telescopic plate 18 slides through the second end cover 24 of the rotating cylinder 14 to realize the up and down movement in the axial direction.

[0037] It should be noted that when the tension disc 19 rotates axially together with the telescopic plate 18, the tension disc 19 can rotate inside the split bushing 16. The installation groove 39 is beneficial to the installation of the dovetail plate 38, and the cover 37 is used to complete the sealing and fixing.

[0038] Further, the docking head includes a telecom integrated joint 17 installed at the ends of two sections of transmission lines 11. The telecom integrated joint 17 has two ports, a plug and a socket. The two ports are respectively installed at both ends of the two sections of transmission lines 11. An annular threaded head 22 is integrally formed on the outer circumference of the plug. A nut 21 is movably sleeved outside the socket. The nut 21 is connected and sealed with the threaded head 22 in a matching manner, and a sealing ring is arranged on the inner wall of the other end of the nut 21.

[0039] See Figure 3, the telecommunication integrated connector 17 is installed at the ends of two sections of transmission lines 11 through its two ports of the plug and the socket respectively, realizing reliable transmission and quick connection and disconnection of electrical signals. When connecting, the annular threaded head 22 integrally formed on the plug tightly meshes with the nut 21 movably sleeved outside the socket. When the operator rotates the nut 21, the thread on the inner wall of the nut 21 forms a firm mechanical lock with the threaded head 22. At the same time, the sealing ring arranged on the inner wall at the other end of the nut 21 deforms during the pressing process and fits with the joint surface to form the first sealing barrier; and the threaded connection between the threaded head 22 and the nut 21 itself constitutes the second sealing protection, forming a double waterproof and dustproof structure.

[0040] Furthermore, a first end cover 23 and a second end cover 24 are respectively arranged at both ends of the rotating cylinder 14, and angular contact ball bearings (not shown in the figure) are arranged between the first end cover 23, the second end cover 24 and the sleeve shaft 25.

[0041] See Figure 4 , due to its special contact angle design, the angular contact ball bearing can bear the combined load from the radial and axial directions at the same time, ensuring that during the high-pressure water gun flushing process, it can not only cope with the rotational torque generated by the rotating cylinder 14, but also bear the change of axial tension and maintain stable operation; the first end cover 23 and the second end cover 24 not only play the role of fixing the bearing, but also form a closed space to prevent seawater and impurities from entering the bearing system.

[0042] It should be noted that angular contact ball bearings (not shown in the figure) can also be arranged between the sleeve shaft 25 and the fixed sleeve 12 to bear the axial tension, and friction damping can also be arranged between the sleeve shaft 25 and the fixed sleeve 12 to facilitate the absorption of energy when the sleeve shaft 25 rotates; and when the rotating cylinder 14 starts to rotate, there is an obvious friction force difference between the rotating cylinder 14 and the sleeve 25. While the rotating cylinder 14 can compress the elastic member 27 greatly, it will also generate obvious radial rotation, causing the guide rod 35 to generate obvious up and down displacement in the guide groove 34, and finally being converted into the displacement pulled by the rising of the tension disc 19, so that the two ends of the connector are close to each other, forming protection for the threaded head connection part of the connector.

[0043] Further, the elastic member 27 is an arc-shaped spring, the arc-shaped spring is arranged along the arc of the annular chamber, and the material is stainless steel, which has corrosion resistance and a stable restoring force.

[0044] See Figure 4 , Figure 5 and Figure 6, the elastic member 27 is designed as an arc spring and is precisely installed along the arc-shaped surface of the annular chamber. During operation, it can adapt to the arc-shaped space of the chamber and provide a uniformly distributed elastic support force. When the connector is impacted by a high-pressure water gun, the elastic member 27 first undergoes elastic deformation to absorb part of the impact energy, reducing the impact damage to the key components of the connector; after the external force decreases or disappears, the elastic member 27 quickly returns to its original state and provides a restoring force in the opposite direction to ensure that the rotating cylinder and related components return to the initial position, guaranteeing that the connector continuously maintains the best working state.

[0045] Furthermore, the number of the flow guiding vanes 15 is 6 - 8, which are evenly distributed along the circumference, and their surfaces are arc-shaped.

[0046] See Figure 1 and Figure 3 , the number of the flow guiding vanes 15 is designed to be 6 - 8 and is evenly distributed along the circumference to form an annular force-bearing structure. When flushing with a high-pressure water gun, the water flow from any angle can be effectively captured by at least one flow guiding vane 15; the surface of each flow guiding vane 15 is designed with an arc shape, which can convert the water flow impact force into a tangential thrust to maximize the utilization of the water flow kinetic energy to drive the rotation of the rotating cylinder 14.
