Description

Technical Field

[0001] The utility model relates to the technical field of ship lock supporting equipment, in particular to an automatic release device for a mooring pile and a floating mooring pile. Background Art

[0002] In inland waterway navigation, when ships travel back and forth from upstream to downstream of rivers, they need to pass through the ship locks at the hydropower stations along the way and travel to the upstream high water level or downstream low water level section respectively. In the lock chamber, in order to prevent the ships from swimming and colliding with each other, and to avoid the ships from rubbing against the lock chamber and gates, causing casualties and property losses, it is necessary to use the ship's cables to tie the mooring piles on both sides of the lock chamber to secure the ship.

[0003] As a mooring facility for ships passing through a ship lock, a floating mooring post has become a basic supporting facility for a ship lock because it can automatically rise and fall with the change of water level when water is filled or discharged in the lock chamber. For example, Chinese patent CN203613513U discloses a floating mooring post, including a buoy, a support frame, a mooring post and a guide roller system. Its mooring pile is fixed on a buoy that can move up and down. When the buoy is working normally, it rises or falls synchronously with the change of water level through the guide roller system. However, because the mooring pile is fixed, if the buoy is stuck by foreign objects when running up and down, or the guide wheel on the inside of the buoy does not slide smoothly, the buoy does not rise or fall with the water level, especially when it does not fall with the drop of water level, the ship moored on the mooring pile may be pulled by the cable on the mooring pile on the stuck buoy when the water level drops, because the cable cannot be released in time. The danger of overturning occurs.

[0004] In response to this, a new type of floating mooring bollard with automatic release function has emerged. Chinese patent CN113774882B proposes a type of floating mooring post release device for ship locks, including a bollard sleeve rocker pulley assembly, a pressure plate spring energy storage assembly and a release locking assembly; the bollard sleeve rocker pulley assembly is arranged on a buoy bracket, the pressure plate spring energy storage assembly is arranged below the bollard sleeve rocker pulley assembly and contacts the bollard sleeve rocker pulley assembly, and the pressure plate spring energy storage assembly is provided with a release locking assembly. When the mooring force exceeds the set threshold, the pulley rolls over the vertex of the triangular slope, the pulley loses the bottom constraint, the bollard sleeve can rotate significantly, and the cable is released.

[0005] However, this type of floating mooring bollard with automatic release function still has certain problems. It uses a pressure plate spring energy storage component as a force threshold limiter, and it can cause release when subjected to horizontal or vertical forces. However, the ship is fixed in the lock with mooring bollards for horizontal fixation to prevent the hull from shaking and touching when the water level changes. If horizontal force can also cause release, it will cause loose fixation during use, reducing the safety factor. In addition, there are many triggers and torsion spring structures in the device, and the structure is relatively complex, so the probability of failure is relatively high, which is not conducive to long-term use. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an automatic release device for a mooring pile and a floating mooring pile, which solves the problems in the prior art that horizontal force may cause release, affect safety performance, and has a complex structure and a high probability of failure.

[0007] According to an embodiment of the utility model, a mooring pile automatic release device comprises a rotating shaft, a rotating support rotatably mounted on the rotating shaft, and a mooring pile movably mounted on the rotating support, wherein the rotating shaft is fixedly arranged, and the rotating support is just sleeved outside the rotating shaft, so that the rotating support can rotate freely in a horizontal plane;

[0008] A slide groove parallel to the central axis of the rotating shaft is provided on one side of the rotating support, the mooring pile is provided on a side close to the slide groove, and a slider is provided on the side of the mooring pile, and the slider is slidably provided inside the slide groove so that the mooring pile and the slider can and can only move along the direction of the slide groove, and the rotating support is provided with a support plate perpendicular to the direction of the slide groove on one side of the slide groove, and a blank area is provided between the support plate and the end face of the slide groove, and the length of the slider is less than the length of the blank area, so that it can slide to the blank area and completely leave the slide groove;

[0009] A spring is coaxially connected to the end surface of the mooring pile close to the support plate. The spring is parallel to the direction of the slide slot and the free end of the spring abuts against the support plate. When the spring bears the weight of the mooring pile and maintains a balanced state, the slider is located inside the slide slot.

[0010] Furthermore, the rotating support is provided with a seat hole which exactly matches the diameter of the rotating shaft, one end of the rotating shaft is fixedly arranged, and the other end passes through the seat hole and extends to the outside of the rotating support to form a free end.

[0011] Furthermore, a thread is provided on the outside of the free end, and a plurality of fastening nuts are also threadedly connected to the outside of the free end, and the contact surface between the fastening nuts and the rotating support is a smooth surface.

[0012] Furthermore, the slide groove is a dovetail groove, and the slider is a trapezoidal structure that matches the cross-sectional shape of the slide groove.

[0013] Furthermore, the sliding groove is closed at one end away from the support plate, and is open at one end close to the support plate.

[0014] Furthermore, a baffle is provided at one end of the slide groove away from the support plate, the baffle closes the corresponding end surface of the slide groove, and the baffle is detachably connected to the slide groove.

[0015] Furthermore, an anti-fall rope is provided between the mooring pile and the rotating support.

[0016] Furthermore, an anti-falling rope is symmetrically arranged on both sides of the slide groove, and both ends of the anti-falling rope are detachably connected to the mooring pile and the rotating support.

[0017] The technical principle of the utility model is: the slide groove limits the sliding of the slider and the mooring pile to only slide in the vertical direction, so it does not affect the fixation of the mooring pile to the hull in the horizontal direction; when the water level drops and the buoy is stuck, the cable pulls the slider and the mooring pile in a downward direction, driving the slider to slide downward along the slide groove and finally detach from the empty area, thereby achieving the disengagement of the slider and the slide groove, and the mooring pile is no longer fixed, so that the hull can float freely without the problem of capsizing.

[0018] The utility model also provides a floating mooring pile, comprising a buoy, on which the above-mentioned mooring pile automatic release device is installed.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model uses a spring to limit the slider in the slide groove, so that it will not fall out before the vertical force reaches the threshold, and the slider cannot slide in the horizontal direction. Therefore, when the buoy floats normally, it will not affect the fixing effect of the mooring pile on the ship, and the safety performance under normal use is maintained;

[0021] 2. The utility model only utilizes the cooperation of a slider, a slide groove and a spring to achieve the required automatic tripping function. It has a simple structure and extremely high reliability. It is not prone to failure even when used for a long time in a humid environment such as a ship lock. The automatic tripping function can be kept in normal use for a long time, thereby improving the safety factor of the ship lock and reducing maintenance time and cost.

[0026] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 As shown, an embodiment of the utility model proposes an automatic release device for a mooring pile, comprising a rotating shaft 1, a rotating support 2 rotatably mounted on the rotating shaft 1, and a mooring pile 3 movably mounted on the rotating support 2. The rotating shaft 1 is fixedly arranged, and the rotating support 2 is just sleeved on the outside of the rotating shaft 1, so that the rotating support 2 can rotate freely in a horizontal plane.

[0028] Rui Figure 2 As shown, in a specific solution, the rotating support 2 is provided with a seat hole that matches the diameter of the rotating shaft 1. One end of the rotating shaft 1 is fixed, and the other end passes through the seat hole and extends to the outside of the rotating support 2 to form a free end. The inside of the seat hole and the outside of the rotating shaft 1 are both smooth surfaces, thereby reducing the friction resistance during rotation, so that when the ship shakes due to changes in water level, the force direction of the cable and the projection of the force direction of the mooring pile 3 on the horizontal plane are collinear, so that the cable is not easy to interfere with other components, avoiding friction, obstruction, etc. of the cable, which affects the stability of the ship. Preferably, a lubrication structure such as a ball bearing can also be set between the rotating shaft 1 and the seat hole to further improve the rotation performance.

[0029] In a further solution, the free end is provided with a thread on the outside, and a plurality of fastening nuts 4 are also threadedly connected to the free end, and the contact surface between the fastening nuts 4 and the rotating support 2 is a smooth surface. In this embodiment, two fastening nuts 4 are arranged in parallel at the top of the free end to ensure that the rotating support 2 is stably and firmly installed on the rotating shaft 1, and the bottom of the fastening nut 4 is also set to a smooth surface to reduce the friction effect on the contact of the top end surface of the seat hole during rotation.

[0030] A slide groove 5 parallel to the central axis of the rotating shaft 1 is provided on one side of the rotating support 2, the mooring pile 3 is provided on the side close to the slide groove 5, and a slider 6 is provided on the side of the mooring pile 3, the slider 6 is slidably provided inside the slide groove 5, so that the mooring pile 3 and the slider 6 can and can only move along the direction of the slide groove 5, the rotating support 2 is provided with a support plate 21 perpendicular to the direction of the slide groove 5 on one side of the slide groove 5, a blank area is provided between the support plate 21 and the end face of the slide groove 5, the length of the slider 6 is less than the length of the blank area, so that it can slide to the blank area and completely leave the slide groove 5. A spring 7 is coaxially connected to the end face of the mooring pile 3 close to the support plate 21, the spring 7 is parallel to the direction of the slide groove 5 and the free end of the spring 7 is in contact with the support plate 21, when the spring 7 bears the weight of the mooring pile 3 to maintain a balanced state, the slider 6 is located inside the slide groove 5.

[0031] In this embodiment, the rotating support 2 is provided with connecting plates 22 extending in parallel on both sides of the slide 5. The connecting plates 22 are right-angled trapezoidal structures, wherein the slide 5 is provided at the top of the opposite side of the connecting plate 22, and a blank area is formed below. Considering that in actual processing, the rotating support 2 is a steel hollow shell structure, and the slide 5 needs to cooperate with the slider 6 to withstand the tension of the cable, and it may be unstable if it is directly set outside. In this embodiment, the connecting plates 22 are added to assist the installation of the slide 5, and the slide 5 is better fixed, so that the rotating support 2 is not easily damaged when it is subjected to the huge tension of the hull shaking.

[0032] In this embodiment, the chute 5 is preferably a dovetail groove, and the slider 6 is a trapezoidal structure that matches the cross-sectional shape of the chute 5. In this way, the slider 6 can be limited by a simple structure so that it can only move in the vertical direction. At the same time, the dovetail groove transmits the horizontal pulling force on the slider 6 to the chute 5 along a larger contact surface, reducing the pressure and preventing the chute 5 from being damaged by excessive local pressure.

[0033] The end of the chute 5 away from the support plate 21 is closed, and the end close to the support plate 21 is open, so that the chute 5 will not fall out from the top of the chute 5 due to unexpected factors, and is stably maintained inside the chute 5 under the support of the spring 7, playing a fixing effect in the horizontal direction. Further, a baffle 51 is provided at the end of the chute 5 away from the support plate 21, and the baffle 51 closes the corresponding end surface of the chute 5, and the baffle 51 is connected to the top of the chute 5 by screws, which is a detachable connection. The detachable baffle 51 can simplify the installation process, and the slider 6 can be embedded from the top of the chute 5 after removing the baffle 51.

[0034] Preferably, in this embodiment, an anti-fall rope 8 is further provided between the mooring pile 3 and the rotating support 2. Furthermore, an anti-fall rope 8 is symmetrically provided on both sides of the slide 5, and the two ends of the anti-fall rope 8 are detachably connected to the mooring pile 3 and the rotating support 2. In specific implementation, mounting heads are provided at both ends of the anti-fall rope 8, and gaskets with holes are provided on the mounting heads. The gaskets cooperate with the mounting seats extending from the bottom of the mooring pile 3 and the bottom of the rotating support 2, and then assisted by screws and nuts, so as to achieve detachable fixation. When the mooring pile 3 and the slider 6 are subjected to a downward pulling force, they are separated from the slide 5 from the empty area, and are automatically released. They will be pulled by the anti-fall rope 8, and the mooring pile can be reused after being manually reinstalled, so as to prevent the mooring pile 3 from falling into the water and being difficult to salvage.

[0035] like Figure 3 As shown, the utility model also provides a floating mooring pile, including two cylindrical buoys 9 arranged up and down, the two buoys 9 are fixedly connected by a bracket 91, and rollers 92 that match the tracks on both sides of the gate are provided on both sides of the buoys 9. In this embodiment, each buoy 9 is provided with a mooring pile automatic release device at the edge position of the top of the buoy 9 facing the middle of the ship lock, so that it is connected with a cable respectively, thereby improving the safety factor.

[0036] When the automatic release device of the mooring pile of the utility model is in use, if the buoy 9 works normally, the mooring pile 3 is only subjected to the pulling force in the horizontal direction, and is stuck in the chute 5 together with the slider 6 to realize the fixing function. When the water level drops and the buoy 9 is stuck, the cable pulls the slider 6 and the mooring pile 3 in a downward tilted direction, driving the slider 6 to slide down along the chute 5, and finally detaching from the empty area, so that the slider 6 and the chute 5 are released, and the mooring pile 3 is no longer fixed, so that the hull can float freely without the problem of capsizing. At the same time, the anti-fall rope 8 is connected to the bottom of the mooring pile 3, so that the mooring pile 3 falls after being separated from the rotating support 2, and the cable set on the mooring pile 3 can be detached from the top thereof, completely releasing the connection with the mooring pile 3, and floating freely with the water level change, avoiding capsizing, and also avoiding pulling the mooring pile 3 off and falling into the water. After that, the mooring pile 3 is manually restored to its original position, and can be used again to fix the cable.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
