Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lock equipment application technology, and in particular relates to an energy storage gate anti-collision warning device. Background Technology
[0002] When ships pass downstream through the lock, the upper gate is open and the lower gate is closed. At this time, the water level difference of tens of meters between upstream and downstream is separated by just one gate in front of and behind the lower gate. Ships enter the lock sequentially. If a ship entering the lock fails to brake, it will collide with the lower gate. If the gate fails, it could potentially cause irreparable damage to the downstream area. Therefore, the "General Design Code for Locks" recommends that Class I to III locks should have anti-collision facilities installed on the upstream piers of the lower gate.
[0003] Currently, most locks do not have anti-collision warning devices. However, with the increasing size of ships and the construction of high-head locks, it is essential to install anti-collision warning devices on the lock gates. Existing lock anti-collision warning devices mainly fall into two categories: 1. Rigid anti-collision warning devices: The anti-collision steel wire rope is rigidly connected to the guide frame, which can move up and down under the drive of a winch. The anti-collision steel wire rope is equipped with warning signs. When a ship collides with the wire rope, the pin at the end of the wire rope shears off, providing self-protection. This type of anti-collision warning device primarily serves as a warning and cannot buffer, dissipate energy, or intercept ships. 1. When a ship passes through the lock, the barrier steel cable is lowered to the bottom of the water via the gate hoist; 2. The energy dissipation and anti-collision warning device consists of an anti-collision chain that bypasses the buoy frame and is then converted into a steel cable. The steel cable is wound around a lifting drum, and the energy dissipation counterweight is connected to another drum via the steel cable. Torque is transmitted between the two drums via a clutch. When a ship collides with the anti-collision chain, the chain drives the lifting drum to rotate, which in turn drives the energy dissipation drum to rotate via the clutch, thereby raising the counterweight and stopping the ship. When a ship passes through the lock, the lifting drum lowers the anti-collision chain until it sinks to the bottom of the water.
[0004] Although this scheme can intercept ships, it has the following problems: (1) The clutch is easily damaged. The impact energy of the ship needs to be transmitted through the clutch. The clutch has limited energy and is easily damaged, which is not suitable for the trend of larger ships; (2) The connection between the arresting chain and the wire rope is troublesome. When the ship passes through the lock, the arresting rope needs to be lowered to the bottom of the water. The wire rope is relatively flexible and it is difficult to sink to the bottom of the water smoothly. Therefore, the scheme of connecting the chain and the wire rope must be adopted. The lowering part uses the chain, and the lifting drum winding part uses the wire rope. The joint of the two reduces the load-bearing capacity. The selection of the joint position is more troublesome. It is also easy to get stuck during lifting and lowering; (3) The state of the arresting chain sinking to the bottom of the water is difficult to control. After all, the weight of the arresting chain is not large. When it sinks to the bottom of the water, it is not easy to control its state underwater by its own weight. If the arresting cable does not sink to the bottom of the water sufficiently, it may affect the navigation of the ship and pose a certain risk. Utility Model Content
[0005] This utility model addresses the problems existing in existing ship lock anti-collision warning devices by proposing an energy storage gate anti-collision warning device that is ingeniously designed, simple in structure, easy to control, and can effectively intercept ships.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an energy storage gate anti-collision warning device, including a blocking steel wire rope, a lifting system and a fixed pulley symmetrically distributed on the top of the gate walls on both sides of the lock chamber, and a steel wire rope guide frame and a rope counterweight installed in the gate wall slot. The bottom of the steel wire rope guide frame is provided with an arc-shaped guide groove. One end of the blocking steel wire rope is connected to the rope counterweight in the gate wall slot on one side of the lock, and the other end passes through the fixed pulley on the top of the gate wall on the same side, then turns downward and passes through the guide groove at the bottom of the steel wire rope guide frame on the same side, crosses the lock chamber, passes through the guide groove at the bottom of the steel wire rope guide frame on the other side, then passes upward through the fixed pulley, and turns back to connect to the rope counterweight on the other side. The lifting system is connected to the steel wire rope guide frame, and the lifting system is used to control the height of the steel wire rope guide frame in the gate wall slot.
[0007] Preferably, the top of the wire rope guide frame is provided with a lifting pulley, and the lifting system includes a winch installed on the top of the gate wall and a rope drum installed on one side of the winch. A rope is wound on the rope drum, one end of which is wound on the rope drum, and the other end passes downward through the lifting pulley and then folds upward to connect to the winch. The weight of the wire rope guide frame is 1.5 to 2 times the weight of the rope counterweight.
[0008] Preferably, the gate wall and gate slot are arranged in a convex shape, and guide wheels are provided on both sides of the wire rope guide frame, with the guide wheels fitting against the wall of the gate wall and gate slot.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides an energy storage gate anti-collision warning device. By directly connecting the blocking steel wire rope to the rope counterweight, the clutch is eliminated, avoiding the problem of the entire energy storage gate anti-collision warning device becoming unusable due to clutch failure. Simultaneously, by replacing the chain rope assembly with the entire blocking steel wire rope design, the problems of limited joint load-bearing capacity, complicated joint location selection, and easy jamming are effectively avoided. Furthermore, the steel wire rope guide frame only provides guidance, preventing the movement of the blocking steel wire rope from affecting the guide frame. At the same time, the lifting system controls the raising and lowering of the steel wire rope guide frame and the straightening of the blocking steel wire rope by the rope counterweight, ensuring the descent depth and state of the blocking steel wire rope underwater, thus preventing its impact on ships.

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0014] Example 1, such as Figures 1-4 As shown, this embodiment aims to provide a gate anti-collision warning device that is structurally stable, simple and reliable, and can effectively block ships and protect the gate. To achieve the above objectives, the energy storage gate anti-collision warning device provided in this embodiment includes a blocking steel wire rope 1, a lifting system 2 and a fixed pulley 3 symmetrically distributed on the top of the gate walls 7 on both sides of the lock chamber, and a steel wire rope guide frame 4 and a rope counterweight 5 installed in the gate wall slot 71. The above equipment is common equipment in existing anti-collision warning devices, and therefore, it will not be described in detail in this embodiment.
[0015] Unlike the existing wire rope guide frame 4, in this embodiment, the bottom of the wire rope guide frame 4 is provided with a guide groove 41. At the same time, one end of the blocking wire rope 1 is connected to the rope counterweight 5 in the lock groove 71 of the lock wall on one side of the lock chamber, and the other end passes through the fixed pulley 3 at the top of the lock wall 7 on the same side, and then folds down and passes through the guide groove 41 at the bottom of the wire rope guide frame 4 on the same side. The guide groove is arc-shaped, and its purpose is to adjust the blocking wire rope 1 from a vertical or horizontal state to a horizontal or vertical state.
[0016] Since the fixed pulley 3 is located below the rope counterweight 5 and the wire rope guide frame 4, the blocking wire rope 1 needs to bend downwards after passing through the fixed pulley 3 in order to pass through the guide groove 41. After passing through the guide groove 41, the blocking wire rope 1 crosses the lock chamber to reach the other side of the lock chamber. Then, it passes through the guide groove 41 at the bottom of the wire rope guide frame 4 on the other side, passes upwards through the fixed pulley 3, and is then bent back to connect to the rope counterweight 5 on the other side. That is, the two ends of the blocking wire rope 1 are respectively connected to the rope counterweight 5 on both sides of the lock chamber, while the fixed pulley 3 and the guide groove 41 at the bottom of the wire rope guide frame 4 only serve as guides. In this way, since the two ends of the blocking wire rope 1 are connected to the rope counterweight 5, the blocking wire rope 1 is always kept taut under the action of gravity, so that its state is consistent whether it is on the water surface or underwater.
[0017] Of course, the guide groove 41 can also adopt a pulley structure, which can also achieve the guiding function. Considering the convenience of processing and service life, the structure of the guide groove 41 is preferred.
[0018] Meanwhile, since the arresting wire rope 1 is directly connected to the rope counterweight 5 and the wire rope guide frame 4 only plays a guiding role during the ship interception process, the problem of limited energy bearing capacity and easy damage of the clutch setting is avoided.
[0019] To facilitate the interception and release of ships, in this embodiment, the lifting system 2 is connected to the wire rope guide frame 4. The lifting system 2 is used to control the height of the wire rope guide frame 4 within the gate wall slot 71. The lifting system 2 can be a winch, or a combination of a long-stroke hydraulic cylinder, a motor, and a lead screw.
[0020] In this way, when it is necessary to intercept a ship, the lifting system 2 controls the wire rope guide frame 4 to rise. At this time, the rope counterweight 5 will move downward, while the blocking wire rope 1 will move above the water surface with the wire rope guide frame 4 and be in a state of alert.
[0021] Under accident conditions: When the ship's speed loses control while entering the lock, the bow strikes the arresting wire rope 1, as follows: Figure 4As shown, the wire rope is pulled outward, the rope counterweight 5 continuously raises the height, the position of the wire rope guide frame 4 remains unchanged, the ship's kinetic energy is converted into the gravitational potential energy of the rope counterweight 5 for storage, and the ship's speed is reduced to 0 within a safe braking distance, effectively protecting the lock gate 6.
[0022] When the ship exits the lock gate 6, the lifting system 2 adjusts the wire rope guide frame 4 to the bottom of the water, and the blocking wire rope 1 sinks to the bottom of the water at the same time. The blocking wire rope 1 lies straight at the bottom and will not obstruct navigation. At this time, the rope counterweight 5 is raised to the top.
[0023] Considering that the lifting system 2 needs to drive the rope counterweight 5 to rise and fall, if a hydraulic cylinder structure is used, the hydraulic pressure needs to be large, the stroke is long, and the cost is high. If a motor and lead screw structure is used, the pressure is large and there may be stability problems. Therefore, in this embodiment, a lifting system 2 is specially provided. Specifically, a lifting pulley 42 is provided on the top of the wire rope guide frame 4. The lifting system 2 includes a winch 21 set on the top of the gate wall 7 and a rope drum 22 set on one side of the winch 21. The winch 21 is a structure of motor and drum. A rope 23 is wound on the rope drum 22. One end of the rope 23 is wound on the rope drum 22, and the other end passes downward through the lifting pulley 42 and then folds upward to connect to the winch 21. At the same time, the weight of the wire rope guide frame 4 is 1.5 to 2 times the weight of the rope counterweight 5.
[0024] In this way, when the wire rope guide frame 4 needs to be lowered, it can be lowered by its own weight, and when it needs to be raised, the wire rope guide frame 4 is raised by the winch 21 winding the pull rope 23.
[0025] To ensure the stability of the wire rope guide frame 4 during lifting, the gate wall slot 71 is convex in shape. Guide wheels 43 are installed on three sides of the wire rope guide frame 4, and these guide wheels 43 are fitted into the wall of the gate wall slot 71. The portion of the gate wall slot 71 used to house the wire rope guide frame 4 has enough space to accommodate it, thus ensuring the stability of the wire rope guide frame 4 during lifting.
[0026] The above setup effectively intercepts and warns against ships, while the entire device is simple in structure, reliable, and inexpensive to use and install, making it suitable for large-scale deployment.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
