Description

Technical Field

[0001] The utility model relates to the technical field of self - floating pier anti - collision devices, in particular to a split - type pier anti - collision device. Background Technique

[0002] Water piers are widely used in fields such as water bridges, playing a role in supporting and fixing water projects. In recent years, ship - hitting pier accidents at home and abroad have been common. They not only cause serious losses such as the collapse of water projects and the destruction of ships and deaths of people, but also may cause pollution problems such as the intrusion of toxic chemicals into the water due to the leakage of the hull, directly or indirectly affecting people's lives.

[0003] The invention patent with the publication number of CN118110134A discloses a self - floating caisson for water piers and its installation method, which includes a plurality of fixed rods and floating boxes. Adjacent two floating boxes are arranged at intervals; the peripheral side of the floating box includes a fixed surface and an impact surface. The fixed surface is the side of the floating box close to the pier, and the fixed surface is tangent to the peripheral side of the pier; the impact surface is the side of the floating box far from the pier. By making the tangent position of the fixed surface and the pier not be in the middle of the fixed surface and making the straight line passing through the center line of the pier and perpendicular to the impact surface be in the middle of the impact surface, the floating box can slide along the tangent direction between it and the pier after being impacted. By arranging a plurality of floating boxes at intervals, the intermittent resistance of the remaining floating boxes can be used to offset part of the energy of the impacted floating box, thereby reducing the impact intensity on the pier.

[0004] In the above - mentioned technical solution, in order to reduce the processing difficulty and transportation difficulty of the floating box, the floating box is divided into two parts, namely a bottom box and a top box, and the bottom box and the top box are fixed by screws and nuts. However, the overall height of the combined structure of the screw and the bottom box is greater than the overall height of the floating box. When transporting the bottom box, there will be a problem of over - height transportation. Content of the Utility Model

[0005] In view of this, the utility model provides a split - type pier anti - collision device, which can reduce the height of each component of the floating cylinder, avoid the problem of over - height transportation, and improve the transportation convenience of the floating cylinder.

[0007] The floating cylinder includes an upper floating ring and a lower floating ring. The upper floating ring is abutted and arranged above the lower floating ring. Both of them are sleeved on the outside of the pier and float on the water surface;

[0008] The fixing mechanism includes two limiting plates and a pin shaft. The two limiting plates are respectively fixedly arranged on the circumferences of the upper floating ring and the lower floating ring, and respectively enclose a first fixing hole and a second fixing hole with them; the pin shaft is detachably fixed in the first fixing hole and the second fixing hole.

[0009] Based on the above technical solution, preferably, the pin shaft has a straight rod-like structure;

[0011] More preferably, the cross-section of the pin shaft is the same as the cross-sections of the first fixing hole and the second fixing hole.

[0012] More preferably, the cross-section of the pin shaft is semi-circular.

[0013] Based on the above technical solution, preferably, the floating cylinder further includes a clamping plate. The clamping plate is abutted and fixed between the upper floating ring and the lower floating ring.

[0014] Based on the above technical solution, preferably, when the floating cylinder floats in water, the water surface is below the fixing mechanism, and the lower floating ring is made of a watertight material.

[0015] More preferably, the cross-sections of the upper floating ring and the lower floating ring are equal, and the height of the upper floating ring is not greater than the height of the lower floating ring.

[0016] Based on the above technical solution, preferably, it further includes a plurality of rubber fenders. The plurality of rubber fenders are respectively fixedly arranged on one side of the upper floating ring and the lower floating ring close to the bridge pier.

[0019] A split-type bridge pier anti-collision device of the present utility model has the following beneficial effects compared with the prior art:

[0020] (1) By setting the floating cylinder as an upper floating ring and a lower floating ring, and using the limiting plates and the pin shaft on their circumferences to fixedly connect the upper floating ring and the lower floating ring, the height of each component in the floating cylinder is effectively reduced, which can facilitate the transportation of the floating cylinder and avoid the problem of over-height transportation;

Detailed Embodiments

[0030] The following will clearly and completely describe the technical solutions in the present invention in combination with the specific embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] As shown Figures 1-5 in the figure, a split-type pier anti-collision device of the present utility model includes a floating cylinder 1, a plurality of fixing mechanisms 2 and a plurality of rubber fenders 3, which are used to float on the water surface 5 and cover the periphery of the pier 4 in the water, so as to prevent the hull from directly hitting the pier 4.

[0032] Among them, the floating cylinder 1 is the main structure of this anti-collision device, which is used to buffer the impact of the ship. The floating cylinder 1 includes an upper floating ring 11 and a lower floating ring 12. The upper floating ring 11 is abutted above the lower floating ring 12. Both of them are sleeved on the outside of the pier 4 and float on the water surface 5. When transporting the floating cylinder 1, since the floating cylinder 1 is divided into two layers, the upper floating ring 11 and the lower floating ring 12 can be transported separately, which is not only convenient for transporting the floating cylinder 1, but also can avoid the problem of over-height transportation.

[0033] The fixing mechanism 2 is used to connect and fix the upper floating ring 11 and the lower floating ring 12. The fixing mechanism 2 includes two limit plates 21 and a pin shaft 22. The two limit plates 21 are respectively fixedly arranged on the peripheries of the upper floating ring 11 and the lower floating ring 12. As Figure 4 shown in the figure, the two limit plates 21 and the upper floating ring 11 and the lower floating ring 12 enclose a first fixing hole 201 and a second fixing hole 202 respectively; the pin shaft 22 is detachably fixed in the first fixing hole 201 and the second fixing hole 202 to connect and fix the upper floating ring 11 and the lower floating ring 12. Since the fixing mechanism 2 is located on the side of the upper floating ring 11 and the lower floating ring 12 and does not occupy the longitudinal space, therefore, it will not cause the problem of over-height of the upper floating ring 11 and the lower floating ring 12 during transportation.

[0034] As Figure 3 shown in the figure, the pin shaft 22 is a straight rod-shaped structure. The fixing mechanism 2 further includes a support plate 23. The support plate 23 is fixedly arranged on the limit plate 21 located on the lower floating ring 12. It is located at the bottom end of the second fixing hole 202 and abuts against the bottom end of the pin shaft 22. When assembling the upper floating ring 11 and the lower floating ring 12, stack the upper floating ring 11 and the lower floating ring 12 so that the first fixing hole 201 and the second fixing hole 202 coincide, and then insert the pin shaft 22 into the coincident first fixing hole 201 and second fixing hole 202, and the upper floating ring 11 and the lower floating ring 12 can be connected and fixed, making the assembly of the two simpler.

[0035] The cross-section of the pin shaft 22 is the same as that of the first fixing hole 201 and the second fixing hole 202, so as to improve the fixing firmness of the pin shaft 22.

[0036] As a preferred embodiment, the cross-section of the pin shaft 22 is semi-circular, that is, the cross-sections of the first fixing hole 201 and the second fixing hole 202 are also both semi-circular; As Figure 5As shown, it can not only prevent the pin shaft 22 from shaking or rotating in the first fixing hole 201 and the second fixing hole 202, ensuring the firm fixation of the upper floating ring 11 and the lower floating ring 12, but also facilitate the processing and assembly of the limiting plate 21. It only needs to directly weld the arc-shaped plate structure on the upper floating ring 11 or the lower floating ring 12.

[0037] The floating drum 1 floats on the water and is vulnerable to water body corrosion. Therefore, an anti-corrosion layer needs to be sprayed on the surfaces of the upper floating ring 11 and the lower floating ring 12. The anti-corrosion layer can use coatings with water isolation and waterproof functions.

[0038] As Figure 3 shown, the floating drum 1 further includes a clamping plate 13. The clamping plate 13 is held and fixed between the upper floating ring 11 and the lower floating ring 12. The clamping plate 13 is preferably made of polytetrafluoroethylene, and its two sides are smooth, which can prevent wear between the upper floating ring 11 and the lower floating ring 12 and damage the anti-corrosion layer on their surfaces. At the same time, the clamping plate 13 is parallel to the water surface, and its end faces the ship. When the anti-collision device is hit by the ship, the clamping plate 13 can also strengthen the structural strength of the floating drum 1 and make it not easily damaged.

[0039] As Figure 1 shown, by adjusting the material and weight of the floating drum 1, when the floating drum 1 floats in the water, the water surface 5 is located below the fixing mechanism 2, that is, the water surface 5 is located on the circumference of the lower floating ring 12 and below the limiting plate 21 on the lower floating ring 12. Thus, it can prevent the fixing mechanism 2 from contacting the water body and reduce its corrosion rate. Since the lower floating ring 12 is in contact with the water body while the upper floating ring 11 is not in contact with the water body, the lower floating ring 12 is made of watertight materials (including watertight structures), and the upper floating ring 11 can not use watertight materials, thereby reducing the processing cost of the floating drum 1. Among them, watertight materials refer to materials that are not invaded or penetrated by water when in contact with water and can maintain the integrity of their functions, such as polyethylene, etc.

[0040] As Figure 1 shown, the cross-sections of the upper floating ring 11 and the lower floating ring 12 are equal. The height of the upper floating ring 11 is not greater than the height of the lower floating ring 12. The height of the upper floating ring 11 can be equal to the height of the lower floating ring 12, so that the upper floating ring 11 and the lower floating ring 12 are of equal size structures, facilitating batch processing of the two. The height of the lower floating ring 12 can also be greater than the height of the upper floating ring 11, so as to better carry the upper floating ring 11.

[0041] The rubber fender 3 is used to buffer between the floating drum 1 and the pier 4. Multiple rubber fenders 3 are respectively fixedly arranged on the sides of the upper floating ring 11 and the lower floating ring 12 close to the pier 4. When the floating drum 1 is hit by the ship, the rubber fender 3 can buffer this impact force and play a role in protecting the pier 4.

[0042] AsFigure 2 As shown, a plurality of fixing mechanisms 2 and a plurality of rubber fenders 3 are arranged at intervals around the center line of the pier 4, thereby improving the stability and balance of the anti-collision device.

[0043] As Figure 3 shown, the pin shaft 22 is a hollow structure, which can not only save the manufacturing material of the pin shaft 22, reduce its manufacturing cost, but also reduce its weight, thereby reducing the overall weight of the anti-collision device and facilitating the floating of the anti-collision device on the water surface 5.

[0044] The usage method of a split-type pier anti-collision device of the present utility model is as follows:

[0045] When installing the anti-collision device, first put the lower floating ring 12 on the outer side of the pier 4, then put the upper floating ring 11 on the outer side of the pier 4, and make the upper floating ring 11 abut against the lower floating ring 12, so that the first fixing hole 201 coincides with the second fixing hole 202 one by one. Finally, insert the pin shaft 22 into the coincident first fixing hole 201 and second fixing hole 202, and the upper floating ring 11 and the lower floating ring 12 can be connected and fixed.

[0046] The above description is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
