Description

Technical Field

[0001] The invention relates to the technical field of ship lock protection structures, and in particular to a temporary protection device for a ship lock hull and a protection method thereof. Background Art

[0002] A ship lock is a box-shaped hydraulic structure that is used to ensure smooth passage of ships and concentrate the water level difference on the waterway. 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, a stepped longitudinal section must be formed to form a concentrated water surface drop. Therefore, special navigation buildings must be used to allow ships to pass through the drop directly. The most commonly used modern navigation building is the ship lock. It is a box-shaped structure consisting of upstream and downstream pilot channels and upstream and downstream lockheads and lock chambers. The ship lock chamber is a box-shaped chamber for mooring ships (or fleets). The water level in the lock chamber is adjusted by filling or draining water in the chamber, so that the ship can be vertically raised and lowered between the upstream and downstream water levels, thereby passing through the concentrated waterway water level difference. When the ship travels from downstream to upstream, the water level in the chamber drops to the same level as the downstream water level, then the gate at the downstream lock is opened, the ship enters the lock chamber, the gate is closed, water is poured in, and when the water level rises to the same level as the upstream water level, the gate at the upstream lock is opened, and the ship can leave the lock and sail upstream through the upstream pilot channel. When the ship travels from upstream to downstream, the lock operation procedure is the opposite.

[0003] During the use of the existing ship lock, after the ship enters the lock chamber, due to the undercurrent caused by the water injection or discharge in the lock chamber, the hull will sway slightly, or the hull will rub against the lock wall or lock door due to misoperation, causing wear between them, reducing the service life of the hull, lock door and lock wall, and increasing maintenance costs. Therefore, a temporary protection device and protection method for the hull of the lock when passing through the lock are designed to solve the problem that the existing hull is easily scratched with the lock wall or lock door in the lock chamber, affecting the service life and causing high maintenance costs. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 5As shown, a temporary protection device for a lock hull includes a protection mechanism 1, a lock door 2 and a lock wall 3. The protection mechanism 1 is installed on the lock door 2 near the bow. The protection mechanism 1 has multiple groups installed on the lock walls 3 on both sides.

[0030] Two ship lock gate bodies 2 are symmetrically arranged, and the ship lock gate bodies 2 are rotatably installed on the ship lock wall body 3. The joint between the two ship lock gate bodies 2 is inclined and protrudes toward the direction of the incoming ship. The ship lock gate body 2 is rotated and opened toward the direction of the incoming ship. A ship lock chamber 4 is formed between the ship lock gate body 2 and the ship lock wall 3, and the water surface in the ship lock chamber 4 is for the ship to pass.

[0031] The protection mechanism 1 is provided with a guide groove 1.1, a floating ball 1.2, a floating body 1.3, a slider 1.6, a spring mounting plate 1.7, a shock-absorbing spring and a buffer 1.11. The guide groove 1.1 is vertically arranged on the ship lock door body 2 and the ship lock wall 3. The floating body 1.3 is slidably mounted in the guide groove 1.1. The floating ball 1.2 is mounted at the bottom of the floating body 1.3. The floating ball 1.2 floats and rises and falls according to the water level line 5. A shock-absorbing spring is mounted on the floating body 1.3. The buffer 1.11 is mounted on the outside of the shock-absorbing spring. The contact plate 1.12 is mounted on the outside of the buffer 1.11. The outside of the contact plate 1.12 contacts the ship hull.

[0032] The float 1.2 is made of polyurethane, and the polyurethane float uses polyurea material as the outer protective layer, and the inside uses polyurethane foam material as the buffer medium. The diameter of the float 1.2 is smaller than the internal size of the guide groove 1.1, and the float 1.2 does not contact the inner wall of the guide groove 1.1. The floating principle controls the lifting and lowering of the protective buffer 1.11, so that the buffer 1.11 is always located above the water level 4 and can contact the hull. The use effect of the buffer 1.11 is better, and the buoyancy of water is used to control the automatic lifting and lowering, which reduces the use of power equipment, is more energy-saving, and has a simpler and more effective structure.

[0033] A guide groove 1.1 is arranged on the outermost side of the lock door 2 facing the incoming ship, and a plurality of guide grooves 1.1 are evenly and vertically arranged on the lock wall 3, with the intervals between the guide grooves 1.1 being 2 meters.

[0034] A strip hole 1.5 is provided in the middle of the outer side of the guide groove 1.1, a slider 1.6 is slidably connected in the strip hole 1.5, the inner side of the slider 1.6 is fixedly connected to the floating vehicle body 1.3, and the outer side of the slider 1.6 is fixedly connected to the spring mounting plate 1.7.

[0035] Auxiliary rollers 1.4 are rollingly mounted on both sides of the floating vehicle body 1.3, and the auxiliary rollers 1.4 roll on the inner wall of the guide groove 1.1.

[0036] The shock-absorbing spring includes a shock-absorbing spring 1.8 and four shock-absorbing springs 2 1.9. One side of the shock-absorbing spring 1.8 and the four shock-absorbing springs 2 1.9 are fixedly connected to a spring mounting plate 1.7. The other sides of the shock-absorbing spring 1.8 and the four shock-absorbing springs 2 1.9 are fixedly connected to a buffer plate 1.10. The four shock-absorbing springs 2 1.9 are evenly distributed around the shock-absorbing spring 1.8. The four shock-absorbing springs 2 1.9 are all inclined.

[0037] The buffer plate 1.10 is fixedly connected to the buffer part 1.11 on the outside, and the buffer part 1.11 is fixedly connected to the contact 1.12 on the outside. The buffer part 1.11 adopts a rubber material cylindrical structure, which can set the buffer distance and provide soft contact. The contact plate 1.12 adopts a rubber material plate. The shock absorbing spring and the rubber material buffer part 1.11 have two-stage shock absorbing and buffering. The external shock absorbing spring is tilted to form a triangular structure with multiple angles, which improves the strength of the shock absorbing spring, avoids damage to the spring caused by longitudinal or lateral displacement caused by collision, has better anti-collision effect, and increases the service life of the equipment.

[0038] A protection method for a temporary protection device for a ship lock hull, comprising the following steps:

[0039] 1. A guide groove 1.1 is vertically drilled on the outermost side of the lock gate 2 and the lock wall 3. A floating vehicle body 1.3 with a floating ball 1.2 at the bottom is installed in the guide groove 1.1. The water level 5 in the guide groove 1.1 is consistent with the water level 5 in the lock chamber 4. The floating vehicle body 1.3 rises and falls in the guide groove 1.1 according to the height of the water level 5 due to the buoyancy of the floating ball 1.2.

[0040] 2. The floating body 1.3 is connected to the external spring mounting plate 1.7 through the slider 1.6. The slider 1.6 moves up and down along the strip hole 1.5, driving the external buffer 1.11 to move up and down along the water level line 5, controlling the buffer 1.11 to always be above the water level line 5, so that the buffer 1.11 effectively contacts the outermost side of the hull.

[0041] 3. The contact plate 1.12 contacts the hull, and the two-stage buffering and decompression of the buffer member 1.11 and the shock-absorbing spring are used to control the hull from having a hard collision with the lock wall 3 and the lock door 2.

[0042] 4. The protective mechanism 1 does not affect the opening and closing of the lock door 2.
