Abstract
Description
Technical Field
[0001] This utility model relates to the field of ship collision avoidance technology, and in particular to a roller-type elastic ship navigation tunnel anti-collision sidewall device. Background Technology
[0002] Ship passage tunnels are an important and new type of vessel passage facility that has emerged in the development of high-head cascade waterway channels in high mountain canyons and rivers. As a very special type of semi-enclosed shallow and narrow waterway, ship tunnels differ significantly from conventional restricted waterway navigation. Their width is only 1 to 2 meters larger than the width of a ship, and the channel depth is limited with little margin. The tunnel cross-sectional coefficient is even smaller. Due to the influence of the channel wall effect and bottom suction effect, ship maneuvering is very difficult.
[0003] Currently, the sidewalls of navigation tunnels are made of ordinary reinforced concrete, which has high rigidity. However, frequent swaying and collisions between ships during navigation can cause damage to the sidewalls, and collisions may even cause collapses, which greatly affects the safety of ship navigation and the structural stability of the tunnel.
[0004] Therefore, it is necessary to develop a new type of device that is suitable for the navigation environment of water tunnels and can effectively protect the safety of ship navigation and the safety of the tunnel sidewall structure. Utility Model Content
[0005] The purpose of this utility model is to provide a roller-type elastic anti-collision sidewall device for navigation tunnels, which aims to solve the problem that frequent swaying and collisions during ship navigation cause damage to the sidewalls of the navigation tunnel, and may even cause collapse, which greatly affects the safety of ship navigation and the structural stability of the tunnel.
[0006] To achieve the above objectives, this utility model provides a roller-type elastic anti-collision sidewall device for navigation tunnels and channels, comprising a wall, a support rod, a connecting rod, a spring sleeve, a shock-absorbing spring, a pressure plate, and an anti-collision roller. The wall has an installation groove. The spring sleeve is detachably connected to the wall and is located on the inner sidewall of the installation groove. The pressure plate is slidably connected to the spring sleeve and is located on the inner sidewall of the spring sleeve. The support rod is fixedly connected to the pressure plate and is located on one side of the pressure plate, and the support rod is slidably engaged with the spring sleeve. The connecting rod is fixedly connected to the support rod and is located at one end of the support rod. One end of the shock-absorbing spring is fixedly connected to the pressure plate and is located on one side of the pressure plate. The other end of the shock-absorbing spring is fixedly connected to the spring sleeve and is located on the inner sidewall of the spring sleeve. The anti-collision roller is rotatably connected to the connecting rod and is located on the outer sidewall of the connecting rod.
[0007] The roller-type elastic anti-collision sidewall device for ship navigation tunnels further includes a pressure ball and a pressure base. The pressure ball is fixedly connected to the pressure plate and is located on one side of the pressure plate. The pressure base is fixedly connected to the spring sleeve and is located on the inner bottom wall of the spring sleeve.
[0008] The roller-type elastic ship navigation tunnel anti-collision sidewall device also includes a high-voltage pulse, which is detachably connected to the support rod and located at the middle end of the support rod.
[0009] The roller-type elastic ship navigation tunnel anti-collision sidewall device also includes multiple pressure relief balls, which are fixedly connected to the anti-collision roller and are located on the outer side wall of the anti-collision roller.
[0010] This utility model discloses a roller-type elastic anti-collision sidewall device for navigation tunnels. In use, the anti-collision roller is made of highly elastic, wear-resistant rubber and connected to a 10cm diameter steel rod via bearings. It can rotate around the rod, reducing friction between the ship and the sidewall while absorbing energy through rubber deformation, thus mitigating collision damage. The rod serves as the main structure for connecting multiple stages of the anti-collision rollers. It is connected to a 20cm diameter spring sleeve via a support rod. A pressure plate supports the expansion and contraction of the shock-absorbing spring, reducing impact energy. The 10cm diameter steel support rod rigidly connects to the rod, and the multi-stage design disperses impact energy. This allows the multi-stage spring sleeve connection to adapt to any channel depth. The combination of the roller structure, elastic rubber, spring sleeves, and multi-stage design achieves comprehensive energy dissipation. The intermittent arrangement is specifically designed for collision scenarios involving short-length ships and small impact angles, reducing damage to the channel sidewall caused by ship swaying and collisions.

[0018] This utility model provides a roller-type elastic anti-collision sidewall device for navigation tunnels and channels, including a wall 101, a support rod 102, a connecting rod 103, a spring sleeve 104, a shock-absorbing spring 105, a pressure plate 106, an anti-collision roller 107, a pressure ball 108, a pressure base 109, a high-voltage pulse 110, and multiple pressure-reducing balls 111. The wall 101 has an installation groove 112.
[0019] The wall 101 has a mounting groove 112. The spring sleeve 104 is detachably connected to the wall 101 and is located on the inner side wall of the mounting groove 112. The pressure plate 106 is slidably connected to the spring sleeve 104 and is located on the inner side wall of the spring sleeve 104. The support rod 102 is fixedly connected to the pressure plate 106 and is located on one side of the pressure plate 106. The support rod 102 and the spring sleeve 104 are slidably engaged. The connecting rod 103 is fixedly connected to the support rod 102 and is located at one end of the support rod 102. One end of the shock-absorbing spring 105 is fixedly connected to the pressure plate 106 and is located on one side of the pressure plate 106. The other end of the shock-absorbing spring 105 is fixedly connected to the spring sleeve 104 and is located on the inner side wall of the spring sleeve 104. The anti-collision roller 107 is rotatably connected to the connecting rod 103 and is located on the outer side wall of the connecting rod 103.
[0020] In this embodiment, the anti-collision roller 107 is made of highly elastic and wear-resistant rubber and is connected to the 10cm diameter steel connecting rod 103 via bearings. It can rotate around the connecting rod 103, reducing friction between the ship and the sidewalls and mitigating collision damage through rubber deformation. The connecting rod 103 serves as the main structure for connecting multiple stages of the anti-collision rollers 107. It is connected to the 20cm diameter spring sleeve 104 via the support rod 102. The pressure plate 106 supports the shock-absorbing spring. The extension and retraction of spring 105 can reduce impact energy. A steel strut 102 with a diameter of 10cm rigidly connects the connecting rod 103 and the spring sleeve 104. The multi-stage design can disperse the impact energy. In this way, the multi-stage spring sleeve 104 can be connected to adapt to any channel depth. The combination of roller structure, elastic rubber, spring sleeve 104 and multi-stage design achieves comprehensive energy dissipation. The intermittent arrangement is specifically adapted to the collision scenarios of short ship length and small impact angle, reducing the damage to the channel sidewall caused by ship swaying and collision.
[0021] Furthermore, the pressure ball 108 is fixedly connected to the pressure plate 106 and is located on one side of the pressure plate 106, and the pressure base 109 is fixedly connected to the spring sleeve 104 and is located on the inner bottom wall of the spring sleeve 104.
[0022] In this embodiment, the impact force is transmitted to the mechanical contacts of the pressure ball 108 and the pressure base 109 through the designed spring sleeve 104 to complete the switching action or signal recording. The adjustable preload spring behind the pressure ball 108 ensures rapid reset after the switching action and can flexibly adjust the sensitivity according to sea conditions and monitoring needs. The entire mechanism is fixed by the elastic support between the shock-absorbing spring 105 and the wall 101, which ensures sufficient rigidity and avoids structural fatigue and damage.
[0023] Furthermore, the high-voltage pulse 110 is detached from the support rod 102 and is located at the middle end of the support rod 102.
[0024] In this embodiment, the high-pressure pulse 110 can automatically adjust the pressure and frequency of the jet pulse according to the wave intensity, the speed of the approaching vessel, and the distance in actual sea conditions: when approaching at high speed, the pulse pressure and frequency will rise synchronously to form a continuous water curtain; when the vessel slows down or detours to a safe area, the system will automatically reduce the frequency and stop jetting, returning to the normal "silent" monitoring mode. Through this closed-loop operation of "sensing-releasing-feedback", the high-pressure pulse 110 water flow not only achieves effective physical isolation of the approaching hull, but also provides a direct and non-destructive safety measure.
[0025] Furthermore, each of the pressure-reducing balls 111 is fixedly connected to the anti-collision roller 107 and is located on the outer side wall of the anti-collision roller 107.
[0026] In this embodiment, the pressure relief ball 111 and the anti-collision roller 107 provide multi-level buffering against waves and external collision forces, which not only protects the internal structure but also avoids malfunctions caused by minor disturbances.
[0027] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
