Description

Technical Field

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

[0002] Weather stations on ocean-going vessels are crucial for modern maritime safety and meteorological data collection. Wind speed and direction sensors, temperature and humidity monitors, and other equipment are typically installed at the highest point on the vessel's hull to obtain accurate data. These systems are inevitably exposed to the harshest marine environment, facing multiple challenges such as seawater erosion and persistent salt spray corrosion. Regular cleaning of the equipment and connectors is essential. Since these devices are typically located on a mast atop the wheelhouse, high-pressure water jets are often used to minimize climbing.

[0003] Chinese patent document (publication number: CN119340725B) discloses a tensile-resistant waterproof and explosion-proof cable connector, specifically relating to the field of cable connection technology. The connector includes a fixing sleeve, the end face of which is slidably sleeved with one end of a clamping rod. The advantages of the present invention are that it can automatically tighten the inner conductor, eliminating the need for clamping, connecting and compacting copper tubes, sealing with a heat shrink sleeve, and overall tightening with a heat shrink tube. This not only simplifies the operation steps, reduces labor, and shortens cable connection time, but also reduces operator requirements and labor costs. In addition, the cable connector is tensile-resistant and the cable and cable connector are completely sealed, making the cable connector waterproof and explosion-proof. The cable connected by the cable connector can be used in extreme environments, expanding the application range of the cable connector. The tensile resistance and waterproof and explosion-proof properties work together, that is, the greater the tensile strength, the less likely a gap will exist between the cable and the cable connector, thereby fully ensuring the waterproof and explosion-proof effect.

[0004] Connectors for wind speed and direction sensors or temperature and humidity monitors are usually installed at the highest point of the hull. During the flushing process with a high-pressure water gun, the operator needs to constantly adjust the impact position of the water gun, and has to adjust his standing position on the deck while holding the water gun. The operation is cumbersome and there are safety hazards at high altitudes. 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 even bend at the docking point, affecting the connection strength and sealing performance, and posing a greater safety hazard to the use of the equipment. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a precision waterproof connector. When the connector is flushed by a high-pressure water gun, the operator does not need to adjust his standing position, and the high-pressure water gun will not cause shaking or bending of the connection of the connector, thereby ensuring the normal operation of the device and extending its service life.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The connector of the present invention is provided with a buffer reset unit. When the connector is subjected to high-pressure water gun flushing, the guide plate is impacted by the water pressure and drives the drum to rotate together. When the drum rotates, under the action of the buffer reset unit, it can not only disperse the high pressure of the water gun flushing, but also enable the drum to rotate for self-cleaning, thereby preventing the connector from being subjected to excessive stamping pressure and causing the connection to shake, loosen or even be damaged. During the rotation of the drum, different parts are flushed by water, thereby avoiding the operator deliberately adjusting the position of the water gun for alignment and cleaning. Specifically, a rotating drum is provided on the periphery of the connector, and guide plates are evenly distributed on the surface of the rotating drum. The sleeve is sleeved on the fixed sleeve, and the rotating drum is sleeved on the outside of the sleeve. An annular chamber is provided between the inner wall of the rotating drum and the outer wall of the sleeve, and an elastic member and two parallel sliding rods are provided inside the annular chamber. The elastic member is installed between the convex rod on the outside of the sleeve and the adjacent sliding rod, and the traction block provided between the two sliding rods is fixedly connected to the inner wall of the rotating drum; when the rotating drum rotates under the cooperation of water pressure and the guide plates, the rotating drum drives the traction block to rotate, and the traction block first squeezes the sliding rod on the corresponding side and compresses the adjacent elastic member, and then drives the sleeve to rotate together; in this process, when the rotating drum and the guide plates are subjected to water pressure impact and rotate, the elastic member will be compressed and then rotated together with the sleeve, thereby buffering the impact of the high-pressure water gun and absorbing energy, thereby preventing the connector from being subjected to excessive impact force and affecting the stability and service life of the structure.

[0019] 2. The connector of the present invention is provided with a tensioning unit. When the connector is subjected to the flushing of the high-pressure water gun, the guide plate is impacted by the water pressure and drives the drum to rotate together. Under the action of the tensioning unit, no matter whether the drum is rotated clockwise or counterclockwise during flushing, the drum drives the lifting ring body axially away from the docking joint, so that the two ends of the connector are further close to each other and stabilized through the tension disk, avoiding the impact of the high-pressure water gun on the threaded joint of the connector causing shaking and even damage to the structure; advantageously, a guide rod is provided on the lifting ring body fixedly connected to the drum, 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 drum is driven by water pressure When the cylinder rotates, the lifting ring body and the guide rod rotate together, and the guide rod slides inside the guide groove on the outer circumference of the sleeve shaft; since the guide groove is a V-shaped arc groove formed by the extension of both sides thereof in the direction away from the docking joint, no matter which direction the rotating drum rotates, it will drive the lifting ring body to move in the direction away from the docking joint, thereby driving the telescopic plate and the tension disk to move together. Under the action of the split shaft sleeve connecting the two tension disks, the displacement generated by the lifting ring body is finally converted into a force to pull the two ends of the connector together, thereby reinforcing the two ends of the connector, ensuring that the threaded joint of the connector is stably docked without shaking, ensuring the normal operation of the equipment, and extending the service life of the connector.

[0020] 3. The split shaft sleeve of the tensioning unit of the present invention connects the tension disks at both ends while also fully surrounding and protecting the threaded joint of the connector, preventing the connection of the connector from directly contacting the marine environment or being sprayed by a water gun, thereby playing an isolation and protection role; advantageously, since the two tension disks are respectively located at both ends of the connector, and when the slide groove of the split shaft sleeve is connected with the tension disk, the split shaft sleeve and the two tension disks are combined to form an independent chamber, and the threaded head connection of the connector is located inside the independent chamber; the independent chamber isolates the threaded head connection of the connector from the external marine air environment, and also blocks the direct spraying of the high-pressure water gun, thereby playing an anti-corrosion or impact damage, ensuring the normal operation of the equipment, and further protecting the stability and service life of the connector.

A sleeve shaft 25 is rotatably provided on the fixed sleeve 12, and a rotating drum 14 is provided on the outer periphery of the sleeve shaft 25. A plurality of guide plates 15 are arranged in an array along the center of a circle on the outer periphery of the rotating drum 14, and an annular chamber is formed between the inner wall of the rotating drum 14 and the outer wall of the sleeve shaft 25; a buffer reset unit is provided 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 drum 14; a tensioning unit is also provided inside the annular chamber, and the tensioning unit extends to the outside of the rotating drum 14 and a tension disk 19 is fixed on the end. The tension disks 19 on the two sets of adaptive tension adjustment components are connected by a split shaft sleeve 16.

[0033] In the present invention, after the line end of the connector is connected, the mounting base 13 is fixed to the adjacent mast or equipment connection plate. Figure 1 , which is the state when the connector is installed. The matching portion of the mounting seat 13 and the fixing sleeve 12 is fixedly connected.

[0034] The fixing sleeve 12 is fixedly mounted on the outer periphery of the transmission line 11 and can also be integrally formed. The outer periphery of the fixing sleeve 12 has the function of fixing the axis and providing a rotation center support for other rotating components.

[0035] Furthermore, the buffer reset unit includes a protruding rod 31 axially arranged on one side of the sleeve shaft 25, and a protruding shoulder 32 fixedly arranged on the outer periphery of the sleeve shaft 25 away from one end of the docking joint; one end of the protruding rod 31 is fixedly connected to the protruding shoulder 32, and the other end of the protruding rod 31 is fixedly connected to the sleeve shaft 25 through a protruding block 33; two sliding rods 26 are arranged along the axis on the side of the annular chamber away from the protruding rod 31, and a traction block 29 is arranged between the two sliding rods 26, and the traction block 29 is fixedly mounted on the rotating drum 14; an elastic member 27 is fixedly arranged on one side of the protruding rod 31, and the other end of the elastic member 27 is fixedly connected to the adjacent sliding rod 26.

[0036] See also Figure 1 、 Figure 4 and Figure 5In the connector of the present invention, a buffer reset unit is provided. When the connector is subjected to high-pressure water gun flushing, the guide plate 15 is impacted by the water pressure and drives the drum 14 to rotate together. When the drum 14 rotates, under the action of the buffer reset unit, it can not only disperse the high pressure of the water gun flushing, but also enable the drum to rotate for self-cleaning, thereby preventing the connector from being subjected to excessive stamping pressure and causing the connection to shake, loosen or even be damaged. During the rotation of the drum 14, different parts are flushed by water, thereby avoiding the operator deliberately adjusting the position of the water gun for alignment and cleaning. Specifically, a rotating drum 14 is provided on the periphery of the connector, and guide plates 15 are evenly distributed on the surface of the rotating drum 14. The sleeve 25 is sleeved on the fixed sleeve 12, and the rotating drum 14 is sleeved on the outside of the sleeve 25. An annular chamber is provided between the inner wall of the rotating drum 14 and the outer wall of the sleeve 25. An elastic member 27 and two parallel sliding rods 26 are provided inside the annular chamber. The elastic member 27 is installed between the protruding rod 31 outside the sleeve 25 and the adjacent sliding rod 26. The traction block 29 provided between the two sliding rods 26 is fixedly connected to the inner wall of the rotating drum 14; when the rotating drum 14 is rotated, the rotating drum 14 is rotated. When ... When the drum 14 rotates under the cooperation of water pressure and the guide plate 15, the drum 14 drives the traction block 29 to rotate. The traction block 29 first squeezes the sliding rod 26 on the corresponding side and compresses the adjacent elastic member 27, and then drives the sleeve shaft 25 to rotate together; in this process, when the drum 14 and the guide plate 15 are impacted by water pressure and rotate, the elastic member 27 is compressed and then rotates together with the sleeve shaft 25, thereby buffering the impact of the high-pressure water gun and absorbing energy, thereby preventing the connector from being subjected to excessive impact force and affecting the stability and service life of the structure.

[0037] It should be noted that the boss 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.

[0038] Furthermore, the tensioning unit includes a lifting ring body 28, which is sleeved on the outer periphery of the sleeve shaft 25. The outer peripheral surface of the sleeve shaft 25 is provided with a guide groove 34, and the guide groove 34 extends to both sides and gradually moves away from the docking head; a guide rod 35 is provided on the lifting ring body 28, and the guide rod 35 extends into the guide groove 34; a dovetail groove 36 is provided on the outer peripheral surface of the lifting ring body 28, and a dovetail plate 38 is slidably arranged in the dovetail groove 36, and the dovetail plate 38 is fixed with a telescopic plate 18 toward the docking head, and the telescopic plate 18 slides through the second end cover 24 of the rotating drum 14, and the end of the telescopic plate 18 is fixedly connected to the tension disk 19, and the tension disk 19 is slidably sleeved on the fixed sleeve 12.

[0039] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7In the present invention, the connector is provided with a tensioning unit. When the connector is subjected to the flushing of the high-pressure water gun, the guide plate 15 is impacted by the water pressure and drives the drum 14 to rotate together. Under the action of the tensioning unit, no matter whether the drum 14 is rotated clockwise or counterclockwise during flushing, the drum 14 drives the lifting ring body 28 axially away from the docking joint, so that the two ends of the connector are further close to each other and stabilized through the tension disk, avoiding the impact of the high-pressure water gun on the threaded joint of the connector causing shaking and even damage to the structure; a guide rod 35 is provided on the lifting ring body 28 fixedly connected to the drum 14, and the lifting ring body 28 is sleeved on the outer periphery of the sleeve shaft 25. The guide rod 35 is slidably installed in the guide groove 34. When the drum 14 is driven by water pressure When rotating, 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 the extension of both sides thereof in the direction away from the docking joint, no matter which direction the rotating drum 14 rotates, it will drive the lifting ring body 28 to move in the direction away from the docking joint, thereby driving the telescopic plate 18 and the tension disk 18 to move together. Under the action of the split shaft sleeve 16 connecting the two tension disks 18, the displacement generated by the lifting ring body 28 is finally converted into a force to pull the two ends of the connector tightly together, thereby reinforcing the two ends of the connector, ensuring that the threaded joints of the connector are stably docked without shaking, ensuring the normal operation of the equipment, and extending the service life of the connector.

[0040] Furthermore, the split shaft sleeve 16 includes two groups of half shaft sleeves, and a slide groove 20 is opened inside the half shaft sleeve corresponding to the two tension disks 19; the slide groove 20 is provided with a semi-ring piece (not shown in the figure) along the side wall of the axis, and the semi-ring piece is connected to the inner wall of the slide groove 20 through a reset elastic member (not shown in the figure); and mounting holes are respectively opened on the two split shaft sleeves 16.

[0041] See also Figure 2 The split shaft sleeve 16 of the tensioning unit of the present invention connects the tension disks 19 at both ends while also fully surrounding and protecting the threaded joint of the connector, preventing the connection of the connector from directly contacting the marine environment or being sprayed by a water gun, thereby playing an isolation and protection role; advantageously, since the two tension disks 19 are respectively located at both ends of the connector, and when the slide 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 are combined to form an independent chamber, and the threaded head connection of the connector is located inside the independent chamber; the independent chamber isolates the threaded head connection of the connector from the external marine air environment, and also blocks the direct spraying of the high-pressure water gun, thereby playing an anti-corrosion or impact damage, ensuring the normal operation of the equipment, and further protecting the stability and service life of the connector.

[0042] It should be noted that the semi-annular piece slides against the tension disc 19, facilitating its rotation. A resilient reset element, installed between the semi-annular piece and the tension disc 19, adapts to tension changes under varying operating conditions, enhancing the connector's adaptability. During high-pressure water jet flushing, the resilient reset element absorbs some vibration and impact energy, further reducing the load on the connector's threaded joint.

[0043] The half ring pieces are correspondingly mounted in the split shaft sleeves 16, and after being combined, a complete ring piece is formed, which slides axially in the slide groove 20. The reset elastic member can be a compression spring, a leaf spring or an elastic rubber pad.

[0044] Furthermore, a mounting groove 39 is provided on one side of the dovetail groove 36 of the lifting ring body 28, and a cover 37 is provided inside the mounting groove 39; a connecting hole 30 is provided on the side of the traction block 29 close to the rotating drum 14, and a through hole corresponding to the connecting hole 30 is provided on the rotating drum 14, and a connecting rod is installed on the outside of the rotating drum 14, and the connecting rod passes through the through hole and extends into the connecting hole 30 to fix the rotating drum 14, the traction block 29 and the lifting ring body 28.

[0045] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The dovetail plate 38 and the dovetail groove 36 are both arranged in an arc shape along the outer periphery of the lifting ring body 28, and 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 maintain a fixed position in the radial direction, and 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 tension disk 19 to move up and down; wherein, the telescopic plate 18 slides through the second end cover 24 of the rotating drum 14 to realize axial up and down movement.

[0046] It should be noted that when the tension disc 19 rotates axially along with the telescopic plate 18, the tension disc 19 can rotate inside the split shaft sleeve 16. The mounting groove 39 facilitates the installation of the dovetail plate 38, and the sealing cover 37 is used to complete the sealing and fixing.

[0047] Furthermore, the docking joint includes a telecommunications integrated joint 17 installed at the ends of the two sections of transmission lines 11. The telecommunications integrated joint 17 has two ports, a plug and a socket, which are respectively installed at the two ends of the two sections of transmission lines 11. The outer circumference of the plug is integrally formed with an annular threaded head 22, and the external movable sleeve of the socket is provided with a nut 21. The nut 21 is matched with the threaded head 22 for sealing, and a sealing ring is provided on the inner wall of the other end of the nut 21.

[0048] See also Figure 3The telecommunications integrated connector 17, with its plug and socket ports, is installed at the ends of two transmission lines 11, respectively, to ensure reliable transmission of electrical signals and quick connection and disconnection. During connection, the annular threaded head 22 integrally formed on the plug tightly engages with the nut 21 that is movably mounted on the outside of the socket. When the operator rotates the nut 21, the threads on the inner wall of the nut 21 and the threaded head 22 form a secure mechanical lock. Simultaneously, the sealing ring on the inner wall of the nut 21 deforms during the tightening process, forming a first sealing barrier against the connector surface. The threaded connection between the threaded head 22 and the nut 21 itself provides a second layer of sealing protection, creating a dual waterproof and dustproof structure.

[0049] Furthermore, a first end cover 23 and a second end cover 24 are respectively provided at both ends of the rotating drum 14 , and angular contact ball bearings (not shown) are provided between the first end cover 23 , the second end cover 24 and the sleeve shaft 25 .

[0050] See also Figure 4 Due to its special contact angle design, the angular contact ball bearing can withstand the combined loads 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 drum 14, but also withstand the changes in axial tension to 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.

[0051] It should be noted that an angular contact ball bearing (not shown in the figure) can be provided between the sleeve shaft 25 and the fixed sleeve 12 to withstand axial tension, and a friction damper can be provided between the sleeve shaft 25 and the fixed sleeve 12 to facilitate the sleeve shaft 25 to absorb energy when rotating; and when the rotating drum 14 initially rotates, there is an obvious friction difference between the rotating drum 14 and the sleeve 25. The rotating drum 14 can greatly compress the elastic member 27 while also producing obvious radial rotation, causing the guide rod 35 to produce obvious up and down displacement in the guide groove 34, which is finally converted into the displacement of the tension disk 19 pulling upward, so that the two ends of the connector are close together, thereby protecting the threaded head connection of the connector.

[0052] Furthermore, the elastic member 27 is an arc spring, which is arranged along the arc of the annular chamber and is made of stainless steel, and has corrosion resistance and stable reset force.

[0053] See also Figure 4 、 Figure 5 and Figure 6Elastic member 27 utilizes an arc-shaped spring design and is precisely mounted along the curved surface of the annular chamber. During operation, it adapts to the chamber's curved space and provides evenly distributed elastic support. When the connector is impacted by a high-pressure water jet, elastic member 27 first elastically deforms to absorb some of the impact energy, mitigating damage to key connector components. Once the external force decreases or disappears, elastic member 27 quickly returns to its original shape, providing a reset force in the opposite direction, ensuring that the drum and related components return to their initial positions and the connector maintains optimal operating conditions.

[0054] Furthermore, the number of the guide blades 15 is 6-8, which are evenly distributed along the circumference and have an arc-shaped surface.

[0055] See also Figure 1 and Figure 3 The number of guide vanes 15 is designed to be 6-8 and evenly distributed along the circumference to form an annular force-bearing structure. When the high-pressure water gun is flushing, the water flow from any angle can be effectively captured by at least one guide vane 15; the surface of each guide vane 15 adopts an arc-shaped design, which can convert the impact force of the water flow into tangential thrust, maximizing the use of the kinetic energy of the water to drive the drum 14 to rotate.

[0056] The present invention illustrates the technical concept of the present invention through the above-mentioned embodiments, but the present invention is not limited to the above-mentioned embodiments. In other words, it does not mean that the present invention must rely on the above-mentioned embodiments to be implemented. Those skilled in the art should understand that relevant improvements to the present invention fall within the scope of protection and disclosure of the present invention.
