Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and more specifically, to a ship lock side wall anti-collision structure for water conservancy engineering. Background Art

[0002] A ship lock is a box-shaped hydraulic structure that is used to ensure the smooth passage of ships and concentrate the water level difference on the waterway. A ship lock refers to a type of "navigation structure". In natural rivers, due to the regulation of flow and channelization of navigation, and in canals due to the limitations of terrain conditions and water surface slope, it is necessary to have a stepped longitudinal section to form a concentrated water surface difference. It is necessary to install an anti-collision structure on the side wall of the ship lock to prevent the ship from colliding with the side wall of the ship lock when passing through the ship lock. However, the existing anti-collision structure of the side wall of the ship lock has the following shortcomings: the anti-collision structure is fixed on the side wall of the ship lock and is in a parallel state with the side wall of the ship lock, and the ship will collide with the anti-collision structure at a vertical angle when passing through the ship lock. At this time, the anti-collision structure cannot play a good anti-collision role on the side wall of the ship lock, and it will cause a large collision between the anti-collision structure and the ship and be damaged. In addition, the anti-collision structure is installed on the side wall of the ship lock in a fixed manner, and it is difficult to automatically adjust according to the height of the ship passing on the water surface of the ship lock, thereby reducing the effect of anti-collision protection for the ship lock. Summary of the invention

[0005] As a further improvement of the present invention, the clamping plate is installed inside the front surface of the anti-collision plate by means of a clamping rod arranged on the edge, and the clamping rod is elastically retracted by a telescopic hose arranged inside the clamping plate. Two clamping plates are provided, which are arranged at the left and right ends of the back of the long board, and five clamping rods and telescopic hoses are equidistantly distributed at the upper and lower ends of each clamping plate.

[0006] As a further improvement of the present invention, a spring rod, a sliding block connecting rod and a sleeve frame are provided on the fixed support plate. The spring rod is fixed inside the fixed support plate. The sliding block slides on the spring rod to apply a connecting elastic force to the connecting rod, so that the anti-collision plate connected to the front end of the connecting rod is elastically offset. The fixed support plate is connected to the sleeve block set at the front end of the mounting frame through the sleeve frame set on the back.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings: Example

[0019] As attached Figure 1 To Attachment Figure 5 As shown: The present invention discloses a ship lock side wall anti-collision structure for a water conservancy project, which comprises an anti-collision plate 1 composed of a side connecting plate 11, a contact mechanism 12 and a fixed support plate 13. The side connecting plate 11 is installed at the end of the contact mechanism 12, and the fixed support plate 13 is supported at the back of the contact mechanism 12. The fixed support plate 13 is installed on the ship lock side wall through a mounting frame 2 arranged at the rear end. The side connecting plate 11 is provided with a roller 111, a hinge shaft 112 and a buffer rod 113. The roller 111 is arranged on the outer side of the connection between the side connecting plate 11 and the anti-collision plate 1 to contact the ship, and the side connecting plate 11 is angularly swung by the hinge shaft 112 arranged inside the connection between the side connecting plate 11 and the anti-collision plate 1. When the plate 11 swings at an angle, it is buffered by a buffer rod 113 arranged between the side connecting plate 11 and the anti-collision plate 1. The contact mechanism 12 is provided with a connecting long plate 121. The connecting long plate 121 contacts the ship through a rubber pad 1211 installed at the front end, and the back of the connecting long plate 121 is clamped and installed on the front surface of the anti-collision plate 1 through a clamping plate 1212. The clamping plate 1212 is clamped and installed inside the front surface of the anti-collision plate 1 through a clamping rod 2121 arranged on the edge, and the clamping rod 2121 is elastically retracted through a telescopic hose 2122 arranged inside the clamping plate 1212. The fixed support plate 13 is provided with a spring rod 131, a sliding block 132, a linkage support rod 133 and The sleeve frame 134, the spring rod 131 is fixed inside the fixed support plate 13, and the sliding block 132 slides on the spring rod 131 to apply a linkage elastic force to the linkage support rod 133, so that the anti-collision plate 1 connected to the front end of the linkage support rod 133 is elastically deflected, and the fixed support plate 13 is connected with the sleeve block 21 set at the front end of the mounting frame 2 through the sleeve frame 134 set at the back. In the present invention, the anti-collision plate 1 is installed on the side wall of the lock through the mounting frame 2. When a ship passes inside the lock and collides with the side wall of the lock, the ship first contacts the side connecting plate 11. Under the connection of the hinge shaft 112, the side connecting plate 11 can be swung and adjusted in angle, and at the same time, the buffer rod 113 is subjected to force on the side connecting plate The plate 11 performs elastic buffering, and at the same time, the roller 111 on the outside of the side plate 11 slides in contact with the ship. The side plate 11 set at an inclined angle and the sliding of the roller 111 change the vertical angle of the ship's impact on the anti-collision plate 1. The ship follows the inclined surface of the side plate 11 and makes parallel contact with the rubber pad 1211 set on the front surface of the anti-collision plate 1. When the ship contacts the anti-collision plate 1, the anti-collision plate 1 is squeezed. At this time, the linkage support rod 133 is linked by force to make the sliding block 132 elastically displaced on the spring rod 131. At the same time, the spring rod 131 applies a linkage elastic force to the linkage support rod 133, so that the anti-collision plate 1 produces elastic buffering protection, thereby improving the anti-collision protection effect on the side wall of the ship lock.

[0020] A preferred technical solution, the side connecting plates 11 are provided with two, and are installed at both ends of the side of the anti-collision plate 1 in an inclined manner. The side connecting plates 11 set at an inclined angle can change the vertical angle of the impact of the ship on the anti-collision plate 1, and the inclination angle of the side connecting plates 11 changes with the impact of the ship under the connection of the hinge shaft 112. The ship follows the inclined surface of the side connecting plate 11 and makes parallel contact with the front surface of the anti-collision plate 1, thereby improving the anti-collision protection effect of the anti-collision plate 1 on the side wall of the ship lock; A preferred technical solution is that there are two snap plates 1212, which are arranged at the left and right ends of the back of the connecting long plate 121, and five snap rods 2121 and telescopic hoses 2122 are equidistantly distributed at the upper and lower ends of each snap plate 1212. The equidistantly distributed snap rods 2121 are elastically snapped into the inside of the anti-collision plate 1, which not only improves the firmness of the snap plate 1212 installed inside the anti-collision plate 1, but also enables the connecting long plate 121 to be quickly disassembled and assembled on the front surface of the anti-collision plate 1. When the rubber pad 1211 on the front surface of the connecting long plate 121 is severely worn after anti-collision contact with the ship, it can be quickly replaced. Embodiment 2: Based on embodiment 1, as shown in the attached Figure 6 To Attachment Figure 7 As shown: The front end of the sleeve block 21 is inserted and installed in the sleeve frame 134, and is locked and connected with the bolt 1341 that runs horizontally through the sleeve frame 134 through the internal thread groove 212 set in the sleeve block 21. The mounting frame 2 is also provided with a guide column 22, and the guide column 22 is passed through the guide groove 211 that runs through the sleeve block 21 with clearance fit, and a connecting long rod 24 is provided at the side end of the sleeve block 21, and a floating ball 23 set at the bottom of the connecting long rod 24 provides up and down buoyancy for the sleeve block 21 on the water surface. In the present invention, after the three mounting frames 2 are installed on the side wall of the ship lock in a horizontal distribution, the three sleeve blocks 21 at the front ends of the three mounting frames 2 are inserted and installed on the fixed support plate 1 3, and then the bolts 1341 on both sides are tightened inside the sleeve frame 134 and locked with the internal thread groove 212 inside the sleeve block 21, so that the sleeve block 21 is firmly installed inside the sleeve frame 134, so that the mounting frame 2 can stably support the anti-collision plate 1 on the side wall of the ship lock. When the anti-collision plate 1 performs anti-collision protection on the side wall of the ship lock, the two floating balls 23 and the two connecting long rods 24 provide up and down buoyancy for the three sleeve blocks 21 according to the height of the water surface, so that the height of the anti-collision plate 1 is automatically adjusted with the height of the water surface, ensuring that the height of the anti-collision plate 1 matches the height of the ship passing on the water surface, thereby improving the anti-collision protection effect of the ship lock.

[0021] A preferred technical solution, wherein three mounting frames 2, guide columns 22 and socket blocks 21 are provided, and two connecting long rods 24 and floating balls 23 are provided. Both the connecting long rods 24 and the floating balls 23 are hollow structures with good buoyancy, and are laterally connected between the three socket blocks 21 through two connecting long rods 24. The two floating balls 23 and the two connecting long rods 24 provide up and down buoyancy for the three socket blocks 21 according to the water surface height, so that the height of the anti-collision plate 1 installed at the front end can be automatically adjusted to ensure that the height of the anti-collision plate 1 matches the height of the ship passing on the water surface, thereby improving the anti-collision protection effect of the lock. Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
