Description

Technical Field

[0001] The utility model relates to the technical field of ship lock protection, in particular to a ship lock multi-level protection structure. Background Art

[0002] A ship lock is a box-shaped hydraulic structure that ensures that ships can pass smoothly through the concentrated water level difference on the channel. It is an important form of navigation structure. Its main function is to adjust the water level in the lock chamber so that ships can rise and fall vertically between the upstream and downstream water levels, thereby overcoming the water level difference in the channel caused by factors such as terrain conditions, water surface slope or flow regulation. With the continuous development of water transportation, the demand for the passage of large ships is increasing. As a key facility for water transportation, the safety and stability of ship locks have become particularly important.

[0003] The Chinese patent discloses: a ship lock structure, patent application number: 202221235425.7, which "includes a ship lock body, a gate is provided on the top of the ship lock body, a gate is rotatably arranged in the gate, a support frame is arranged on the gate, a brush roller for cleaning the silt deposited at the bottom of the gate is arranged on the support frame, a brush handle is arranged on the brush roller, and bristles are arranged on the brush handle, and the bristles are abutted against the bottom wall of the gate, and a driving assembly for driving the brush roller to rotate is arranged on the gate. Before the gate is opened, the brush roller is driven to rotate by the driving assembly, and the brush roller drives the bristles to clean the silt deposited at the bottom of the gate, thereby cleaning the silt near the gate. When the gate is opened, the gate drives the brush roller to rotate, thereby cleaning the deposited silt on the rotating fan-shaped surface of the gate, thereby accelerating the rotation rate of the gate, and thereby improving the use efficiency of the gate."

[0004] Although the ship lock can clean the silt near the gate and the deposited silt on the rotating fan-shaped surface of the gate, thereby accelerating the rotation rate of the gate and improving the efficiency of the gate, the ship lock in this comparative example is not equipped with a protective mechanism. When facing collisions and scratches of ships, its protective ability is limited and it is often unable to withstand the strong impact force from the side of the ship, which can easily cause damage to the inner wall of the lock and affect the normal operation of the lock.

[0016] Beneficial effects of the utility model:

[0017] 1. This kind of multi-stage protection structure of a ship lock, through the extrusion of the sliding sleeve extrusion rod, makes them approach each other and squeezes the extrusion spring in the middle of the sliding rod, and then the extrusion spring is squeezed and deformed, so as to buffer and disperse the collision force, and at this time the protection mounting plate will also contact and squeeze the anti-collision airbag, and the anti-collision airbag will further buffer and disperse the collision force, and further protect the inner wall of the lock chamber, and then the protection mounting plate will also squeeze the inner sliding cylinder, and the inner sliding cylinder will slide in the outer cylinder and squeeze the telescopic spring in the outer cylinder, so as to further buffer the collision force again, and when the ship scrapes the side of the protection mounting plate, it will first contact with the buffer guide plate and The buffer guide plate is squeezed, and the buffer guide plate drives the buffer rod to slide in the second slide groove and squeeze the buffer spring, thereby buffering and dispersing the force scraped to the side wall of the protective mounting plate. At the same time, the shape of the buffer guide plate can guide the colliding or scratching ship to prevent it from further damaging the inner wall of the lock chamber, further improving the overall protection capability of the protection mechanism, thereby realizing multi-level protection, and jointly providing a strong protection capability for the inner wall of the lock chamber. These structures can effectively absorb and disperse the impact force when the ship collides or scratches with the inner wall of the lock chamber, thereby significantly reducing the damage to the inner wall of the lock chamber, and are easy to use.

[0018] 2. This kind of multi-level protection structure of a ship lock starts to rise through the water level in the lock chamber. At this time, the anti-collision airbag at the bottom of the fixed plate will float on the water surface. When the water level continues to rise, the anti-collision airbag will also rise and drive the fixed plate and the protection mechanism to move. Then the slider of the side wall of the fixed plate slides in the first slide groove through the roller, so that the protective mechanism can face the different collision locations of ships of different tonnages, thereby avoiding collisions and scratches outside the protection of the wall of the lock chamber, which causes damage to the ship and the inner wall of the lock channel, thereby improving the flexibility of the protective mechanism and facilitating use.

[0029] For further information, see Attachment Figure 2 and 3 As shown, the protection mechanism includes an anti-collision airbag 6 fixedly connected to the top and bottom of one side of the fixed plate 5, the anti-collision airbag 6 is made of flexible material, the side wall of the fixed plate 5 is fixedly connected to two sliding rods 7, the two sliding rods 7 are fixedly connected to the side wall of the fixed plate 5, the outer walls of the two sliding rods 7 are slidably connected to two sliding sleeves 8, an extrusion spring 9 is fixedly connected between the two sliding sleeves 8, the extrusion spring 9 is sleeved on the outer wall of the sliding rod 7, the side walls of the sliding sleeves 8 are rotatably connected to an extrusion rod 10, one end of the extrusion rod 10 is rotatably connected to a rotating block 11, the side wall of the rotating block 11 is fixedly connected to a protection mounting plate 12, a protection plate 13 is arranged inside the protection mounting plate 12, the protection plate 13 and the protection mounting plate 12 are fixed by bolts, and the outer wall of the protection plate 13 and the protection mounting plate 12 are fixed The outer wall of the plate 12 is adapted, and the side wall of the protective plate 13 is provided with second slide grooves 14 opposite to each other in pairs, and the insides of the second slide grooves 14 opposite to each other are fixedly connected with buffer springs 15, and one end of the buffer spring 15 is fixedly connected with a buffer rod 16, and the buffer rod 16 is slidably connected in the second slide groove 14, and one end of the buffer rod 16 passes through the side wall of the protective mounting plate 12 and is fixedly connected with a buffer guide plate 17, and the shape of the buffer guide plate 17 is arc-shaped.

[0030] When the ship is in the lock chamber, the water level in the lock chamber begins to rise. At this time, the anti-collision airbag 6 at the bottom of the fixed plate 5 will float on the water surface. When the water level continues to rise, the anti-collision airbag 6 will also rise and drive the fixed plate 5 to move. Then, the slider 3 of the side wall of the fixed plate 5 slides in the first slide groove 2 through the roller 4, making the movement of the fixed plate 5 more stable.

At the same time, the shape of the buffer guide plate 17 can guide the colliding or scratching ship to prevent it from further damaging the inner wall 1 of the lock chamber, thereby further improving the overall protection capability of the protection mechanism, thereby realizing multi-level protection and facilitating use.

[0031] For further information, see Attachment Figure 1As shown, an alarm light 21 is fixedly connected to the top of the inner wall 1 of the lock chamber, a contact block 22 is fixedly connected to the middle part of one side of the protective mounting plate 12 close to the fixed plate 5, and an alarm switch 23 is fixedly connected to the middle part of one side of the fixed plate 5 close to the protective mounting plate 12, and the contact block 22 and the alarm switch 23 are on the same horizontal plane.
