Description

Technical Field

[0001] This utility model relates to the technical field of lock auxiliary facilities, specifically to a travel limit device for the guide groove of a floating mooring bollard in a lock. Background Technology

[0002] Floating bollards are an important component of lock systems. They automatically rise and fall with water level changes during the filling and emptying of the lock chamber, providing a mooring platform for vessels entering the lock. This ensures the vessels are relatively fixed to the platform, preventing collisions caused by water flow. Therefore, they are widely used in lock engineering. Within the range from the highest navigable water level upstream to the lowest navigable water level downstream, the floating bollards automatically rise and fall with the water level changes during the filling and emptying of the lock chamber, meeting the mooring requirements for vessels passing through the lock.

[0003] However, during floods, as the water level in the lock chamber rises, the upper structure of the floating mooring bollard may protrude above the top of the guide channel. Typically, the top of the guide channel of the floating mooring bollard is covered with a steel or concrete cover plate. In traditional lock engineering, some measures are taken to open the cover plate during floods to allow the floating mooring bollard to extend freely above the top of the guide channel as the water level rises. Other locks seal and weld the top of the guide channel shut, removing the seal when the flood comes and repairing it after the flood recedes. This method of flood control using floating mooring bollards requires the operating unit to be constantly vigilant, and there are certain safety risks involved, and the countermeasures are complex.

[0004] In summary, there is an urgent need for a travel limit device for the guide channel of a floating mooring bollard in a ship lock to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a travel limiting device for the guide groove of a floating bollard in a lock, which aims to solve the problem that the floating bollard is prone to overshooting and causing danger during the use of existing equipment. The specific technical solution is as follows:

[0006] A travel limiting device for a floating bollard guide channel of a lock includes a stop block and a fastener. The stop block is arranged on the top of the floating bollard guide channel and has a first through hole. The top of the floating bollard guide channel has a second through hole. The fastener passes through the first through hole and the second through hole in sequence and fixes the stop block to the top of the floating bollard guide channel.

[0007] Furthermore, the stop block includes a base plate and a side plate. Two side plates are arranged and fixedly connected to the base plate relative to each other along the height direction. A first through hole is arranged on the side plate, and both side plates are provided with a first through hole.

[0008] Furthermore, the block also includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is arranged along the length direction, and its bottom end is fixedly connected to the base plate. The two sides of the first reinforcing plate are respectively connected to two side plates. The bottom of the second reinforcing plate is fixedly connected to the base plate, and its side is fixedly connected to the first reinforcing plate.

[0009] Furthermore, the travel limit device of the floating mooring bollard guide channel of the lock also includes a buffer mechanism, which is arranged at the lower part of the stop block.

[0010] Furthermore, the buffer mechanism includes a rubber block and a locking element. The rubber block is detachably connected to the bottom of the stop block via the locking element, and a cavity is provided inside the rubber block.

[0011] Furthermore, the rubber block is provided with damping holes, the first end of which is connected to the internal cavity of the rubber block, and the second end of which is connected to the outside.

[0012] Furthermore, the damping holes are arranged at the lower end of the rubber block, and the damping holes face downwards.

[0013] Furthermore, the travel limit device of the floating mooring bollard guide channel of the lock also includes an early warning mechanism, which is arranged inside the cavity.

[0014] Furthermore, the warning mechanism includes a first trigger, which is a pressure trigger. The first trigger is arranged on the top wall of the cavity, and the triggering surface of the first trigger faces the bottom wall of the cavity.

[0015] Furthermore, the warning mechanism also includes a second trigger and an elastic element. The elastic element is fixedly connected to the top wall of the cavity, and the second trigger is fixedly connected to the lower end of the elastic element. The second trigger protrudes downward from the first trigger, and the triggering surface of the second trigger faces the bottom wall of the cavity.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] As the water level rises, the floating bollards in the guide channel rise with it. When the water level exceeds the maximum navigable level and continues to rise to the top of the guide channel, the guide wheel at the top of the floating bollard is pressured by a stop block. At this point, the floating bollard stops rising. The stop block prevents the floating bollard from being pushed out of the guide channel and causing a hazard. Furthermore, when the floating bollard needs to be removed for maintenance, the fasteners and stop blocks can be removed, making it easy to remove the floating bollard from the guide channel. Disassembly and installation are convenient.

[0018] Secondly, during the operation of the lock, ships frequently need to navigate through it. When the lock is moored at high water levels, some locks may experience situations where the guide wheel at the top of the floating mooring bollard moves close to the stop block. When ships enter or exit the lock chamber, the water surface in the chamber fluctuates, and the floating mooring bollard moves with the water surface. During this up-and-down movement, the guide wheel at the top of the floating mooring bollard is prone to colliding with the stop block, which can easily lead to damage to the guide wheel or the stop block.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. These will be described below with reference to...

Detailed Implementation

[0025] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example:

[0028] See Figures 1-3 This embodiment provides a travel limiting device for a floating bollard guide channel of a lock, including a stop block 1 and a fastener 2. The stop block 1 is arranged on the top of the floating bollard guide channel 3, and a first through hole is provided on the stop block 1. A second through hole is provided on the top of the floating bollard guide channel 3. The fastener 2 is arranged to pass through the first through hole and the second through hole in sequence, and the fastener 2 fixes the stop block 1 to the top of the floating bollard guide channel 3.

[0029] It should be noted that the travel limit device for the floating bollard guide channel of the lock is applied to the floating bollard guide channel 3. The stop block 1 is arranged at the top of the floating bollard guide channel 3. In application, under the buoyancy of the water, the floating bollard slides up and down along the floating bollard guide channel 3 as the water level in the lock rises or falls. The guide wheel on the floating bollard is slidably connected in the guide groove of the floating bollard guide channel 3. Specifically, the fastener 2 is a screw, and the stop block 1 is fastened to the upper end of the floating bollard guide channel 3 by the screw, and the stop block 1 is fixedly connected in the guide groove. In addition, after the travel limit device for the floating bollard guide channel 3 is installed at the upper end of the floating bollard guide channel 3, a cover plate needs to be laid on the top of the floating bollard guide channel 3 to cover the floating bollard guide channel and protect the floating bollard guide channel 3.

[0030] Understandably, as the water level rises, the floating bollard in the guide channel 3 rises with the water level. When the water level exceeds the maximum navigable level and the guide wheel at the top of the floating bollard contacts the travel limit device, the guide wheel on the floating bollard is subjected to the pressure of the stop block 1. At this point, the floating bollard stops rising. The stop block 1 prevents the guide wheel at the top of the floating bollard from being pushed out of the guide channel 3 and causing danger. In addition, when it is necessary to remove the floating bollard for maintenance, the fastener 2 and the stop block 1 can be removed, making it easy to take the floating bollard out of the guide channel 3. Disassembly and installation are convenient.

[0031] It should be noted that the top of the floating bollard guide channel 3 is reinforced with thickened steel plates on both sides, allowing the second through hole to penetrate the sidewall of the floating bollard guide channel 3 and extend into the thickened steel plate. The thickened steel plate is welded to the outside of the floating bollard guide channel 3. Simultaneously, the second through hole on the thickened steel plate on the outside of the floating bollard guide channel 3 must not be completely drilled through to prevent it from being filled with concrete during pouring. This arrangement improves the connection stability between the stop block 1 and the floating bollard guide channel 3, and enhances the load-bearing capacity of the stop block 1.

[0032] It is also worth noting that in the design of the floating bollard, when the pontoons on the bollard are fully submerged, the weight of the water displaced by the pontoons is slightly greater than the weight of the bollard itself. This allows the floating bollard to float smoothly on the surface of the sluice gate. However, during floods, when the floating bollard is pressed underwater by the stop block 1, the buoyancy reaction force exerted on the stop block 1 is relatively small. Specifically, when the pontoons on the floating bollard are fully submerged, the weight of the water displaced by the pontoons is 100-300 kg greater than the weight of the floating bollard. That is, during floods, when the floating bollard is blocked by the stop block 1 and the pontoons are fully submerged, the upward force exerted on the stop block 1 by the pontoons is between 100-300 kg. Thus, through structural improvements to the floating bollard, the safety of the floating bollard and pontoons during use is further ensured. It should be noted that a floating mooring bollard includes a buoy, a mooring bollard, and multiple guide wheels.

[0033] Furthermore, the stop block 1 includes a base plate 11 and a side plate 12. Two side plates 12 are arranged, and the two side plates 12 are fixedly connected to the base plate 11 relative to each other along the height direction. A first through hole is arranged on the side plate 12, and both side plates 12 are provided with a first through hole.

[0034] Specifically, the two side plates 12 are flush with the end faces of the two ends of the bottom plate 11, the length of the bottom plate 11 is equal to the width of the guide groove, so that the bottom plate 11 is embedded in the guide groove, and the sides of the two side plates 12 are in contact with the inner surface of the guide groove.

[0035] It is understood that, through the installation of the bottom plate 11 and the side plate 12, the bottom plate 11 blocks the guide wheel at the top of the floating bollard, preventing the floating bollard from being pushed out of the guide groove. The side plate 12 improves the stability of the connection between the stop block 1 and the guide groove, preventing the stop block 1 from detaching from the floating bollard guide groove 3 or becoming damaged under the buoyancy of the pontoon.

[0036] Furthermore, the stop block 1 also includes a first reinforcing plate 13 and a second reinforcing plate 14. The first reinforcing plate 13 is arranged along the length direction, and its bottom end is fixedly connected to the base plate 11. Both sides of the first reinforcing plate 13 are respectively connected to two side plates 12. The bottom of the second reinforcing plate 14 is fixedly connected to the base plate 11, and its side is fixedly connected to the first reinforcing plate 13. Specifically, both the first reinforcing plate 13 and the second reinforcing plate 14 are arranged vertically, and both are fixedly connected to the base plate 11 by welding.

[0037] It is understood that by setting the first reinforcing plate 13 and the second reinforcing plate 14, the structural stability of the stop block 1 is improved, the rigidity of the stop block 1 is enhanced, and the stop block 1 is prevented from being damaged by large deformation during use.

[0038] Furthermore, the travel limit device of the floating mooring bollard guide channel of the lock also includes a buffer mechanism 4, which is arranged at the lower part of the stop block 1.

[0039] It should be noted that during the operation of the lock, ships often need to pass through the lock. When the lock is moored at high water level, some locks may have a situation where the guide wheel on the top of the floating mooring bollard moves close to the stop block 1. When ships enter or exit the lock chamber, the water surface in the lock chamber will fluctuate. The floating mooring bollard will fluctuate with the water surface. During the up and down fluctuation of the floating mooring bollard, the guide wheel on the top of the floating mooring bollard is prone to collision with the stop block 1, which may cause damage to the guide wheel on the top of the floating mooring bollard or the stop block 1.

[0040] It can be seen that, through the setting of the buffer mechanism 4, when the floating bollard rises and fluctuates with the water surface during the water surface movement, the impact of the floating bollard on the stop block 1 is reduced under the action of the buffer mechanism 4. The buffer mechanism 4 reduces the impact force of the floating bollard on the stop block 1 by extending the action time of the guide wheel at the top of the floating bollard on the stop block 1, thereby providing better protection for both the guide wheel at the top of the floating bollard and the stop block 1.

[0041] Furthermore, the buffer mechanism 4 includes a rubber block 41 and a locking member 42. The rubber block 41 is detachably connected to the bottom of the stop block 1 via the locking member 42, and a cavity 411 is provided inside the rubber block 41.

[0042] It is understood that during use, the rubber block 41 acts as a buffer. When the guide wheel on the floating mooring bollard directly impacts the rubber block 41, it undergoes elastic deformation, thus providing a buffering effect. The cavity 411 further increases the deformability of the rubber block 41, allowing for greater deformation. When the guide wheel on the floating mooring bollard impacts the buffer, it travels a longer distance, acts for a longer duration, and experiences less force. The locking element 42 is a screw, which allows for easy disassembly of the rubber block 41, facilitating installation, removal, and replacement.

[0043] Furthermore, the rubber block 41 is provided with a damping hole 412. The first end of the damping hole 412 is connected to the internal cavity 411 of the rubber block 41, and the second end of the damping hole 412 is connected to the outside.

[0044] It is understood that, through the setting of the damping hole 412, when the guide wheel on the floating bollard impacts the rubber block 41, the rubber block 41 deforms, compressing the volume of the cavity 411. At this time, the gas pressure inside the cavity 411 rises, and the gas inside the cavity 411 is discharged outward from the damping hole 412. When the gas inside the cavity 411 is discharged outward from the damping hole 412, it does work on the gas and consumes energy, thereby achieving the effect of buffering and shock absorption for the guide wheel on the floating bollard, and further improving the protection of the guide wheel and the stop block 1 on the floating bollard.

[0045] Furthermore, the damping hole 412 is arranged at the lower end of the rubber block 41, and the damping hole 412 is arranged downward.

[0046] It is known that the downward arrangement of the damping hole 412 allows the gas in the cavity 411 to be discharged smoothly, while preventing rainwater or impurities from entering the cavity 411 through the damping hole 412 on rainy days, which would weaken the buffering effect. At the same time, it prevents the damping hole 412 from being blocked by impurities washed away by rainwater, ensuring the smooth flow of the damping hole 412.

[0047] The buffer mechanism 4 also includes a wear-resistant block 43. The bottom of the rubber block 41 has an arc-shaped contact surface, and the wear-resistant block 43 is fitted onto this arc-shaped contact surface. Specifically, the wear-resistant block 43 is arranged in an arc shape and fits onto the arc-shaped contact surface at the bottom of the rubber block 41. It can be understood that by arranging the bottom of the rubber block 41 in an arc shape, the contact area between the guide wheel on the floating mooring bollard and the rubber block 41 is increased, thereby reducing pressure. Furthermore, the wear-resistant block 43 reduces wear on the rubber block 41, extending its service life. It should be noted that the wear-resistant block 43 is misaligned with the damping hole 412 to prevent the wear-resistant block 43 from clogging the damping hole 412.

[0048] Furthermore, the travel limit device of the floating mooring bollard guide channel of the lock also includes an early warning mechanism 5, which is arranged in the cavity 411.

[0049] It should be noted that in the existing design, when a flood comes, a dedicated person is required to inspect the lock and pay close attention to the status of the floating bollards to prevent them from rising out and causing danger, or from the floating bollards colliding with the top cover plate of the floating bollard guide channel 3, which could lead to damage to the guide wheels on the floating bollards or the top cover plate of the floating bollard guide channel 3, or even cause casualties.

[0050] It is known that through the design of the early warning mechanism 5, the early warning mechanism 5 can issue early warning signals on the status of the floating mooring bollard in a timely manner, and issue an alarm when necessary, so as to achieve the purpose of timely reminder, thereby reducing the labor intensity of patrol personnel and achieving the goal of scientific management.

[0051] Specifically, the warning mechanism 5 includes a first trigger 51, which is a pressure trigger. The first trigger 51 is arranged on the top wall of the cavity 411, and the triggering surface of the first trigger 51 faces the bottom wall of the cavity 411.

[0052] When the guide wheel on the floating mooring bollard compresses the rubber block 41 upward and causes the rubber block 41 to deform, the bottom wall of the cavity 411 moves upward. When the bottom wall of the cavity 411 comes into contact with the first trigger 51, the first trigger 51 sounds an alarm. The patrol personnel take corresponding measures based on the alarm and then deactivate the alarm.

[0053] Furthermore, the warning mechanism 5 also includes a second trigger 52 and an elastic element 53. The elastic element 53 is fixedly connected to the top wall of the cavity 411, and the second trigger 52 is fixedly connected to the lower end of the elastic element 53. The second trigger 52 protrudes downward from the first trigger 51, and the triggering surface of the second trigger 52 faces the bottom wall of the cavity 411, so that the bottom wall of the cavity 411 can contact the second trigger 52 first. In order to enable the first trigger 51 and the second trigger 52 to contact and trigger more stably, two protrusions are provided on the bottom wall of the cavity 411, and the two protrusions correspond to the first trigger 51 and the second trigger 52 respectively.

[0054] It is understood that when the guide wheel at the top of the floating mooring bollard compresses the rubber block 41 upwards, a yellow alarm is triggered when the bottom wall of the cavity 411 comes into contact with the second trigger. At this point, the inspector can take appropriate action. As the guide wheel continues to compress the rubber block 41 upwards, the second trigger 52 is supported by the bottom wall and moves upwards, compressing the elastic element 53 until the bottom wall of the cavity 411 comes into contact with the first trigger 51. In this case, the first trigger 51 issues a red alarm, prompting the inspector to take immediate action. This achieves the purpose of timely alerting the inspector and reflecting the urgency of the work status, making management easier.

[0055] It should be noted that in this embodiment, the elastic element 53 is a compression helical spring. In other embodiments of this application, the elastic element 53 may also be a rubber spring, a gas spring, or other components or structures capable of elastic deformation.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
