Description

Technical Field

[0001] This utility model relates to the field of water traffic collision avoidance technology, and in particular to a collision avoidance protection structure for water traffic. Background Technology

[0002] Water transportation refers to transportation activities carried out in waterways such as rivers, lakes, and oceans using watercraft such as ships and rafts. When ships and rafts are docked, they need to be equipped with anti-collision structures to prevent them from colliding with the port due to failure to brake in time.

[0003] Therefore, in the existing technology of a collision protection structure for water transportation, with the publication number CN221251707U, the entire collision protection plate can be installed on the ship body by attaching the locking block to the inner cavity of the locking slot. When the ship body collides with the navigation mark, the impact force will first act on the rubber hemisphere, which will provide initial cushioning. At this time, the second damper and the second buffer spring will move towards the push rod end under the external impact force. The second damper and the second buffer spring can provide cushioning through their mutual cooperation. At the same time, the sealing plug on the push rod is pushed into the inner cavity of the sealing cylinder. At this time, the cooling water in the inner cavity of the sealing cylinder is finally sprayed out from the mist nozzle through the connecting pipe, thereby reducing the temperature at the impact point and preventing sparks from causing a fire.

[0004] However, when a ship is impacted, the rubber hemisphere will slide against the surface of the object it is in contact with. During the sliding process, friction will occur on the surface of the rubber hemisphere. Due to the roughness of the surface of the object it is in contact with, the surface of the rubber hemisphere is easily worn down by friction. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a collision protection structure for water transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a collision protection structure for water transportation, comprising a fixed base for fixed installation on the hull or building surface, a socket on one side of the fixed base, a plug block inserted into the top edge of the socket, a pin between the socket and the plug block, a connecting plate fixedly installed on one side of the plug block, an energy-absorbing mechanism on one side of the connecting plate, and a connecting plate installed on the connecting plate through the energy-absorbing mechanism, two symmetrically arranged retaining shells hinged to the side of the connecting plate facing away from the fixed base, a rolling ball embedded between the two retaining shells, the surface of the ball being covered with a rubber pad, the inner walls of the two retaining shells being in clearance fit with the surface of the rubber pad, and a plurality of rolling balls embedded in the inner walls of the retaining shells.

[0007] Preferably, a semi-circular ring is fixedly installed on the outer wall of the caliper, and two semi-circular rings form a complete circular ring. The two outer walls of the caliper in the combined state are threadedly connected with an internal threaded ring.

[0008] Preferably, the energy absorption mechanism includes a main damping spring, a plurality of first damping springs and a plurality of second damping springs, wherein the cylinder body and telescopic end of the main damping spring are respectively installed at the center of the surface of the connecting plate and the connecting plate.

[0009] Preferably, a plurality of first damping springs and a plurality of second damping springs are arranged in a circular array around the main damping spring, and a second damping spring is provided between two adjacent first damping springs. An extension seat is fixedly installed on the side of the connecting plate at the position of each second damping spring.

[0010] Preferably, the first damping spring cylinder and the telescopic end are respectively hinged to the connecting plate and the connecting plate, and the second damping spring cylinder and the telescopic end are respectively hinged to the extension seat and the connecting plate, and adjacent first damping springs and second damping springs are distributed in a cross shape.

[0011] Preferably, the side of the connecting plate is hinged with a support plate at both ends of the two clamping surfaces, and the swing edge of the support plate is inserted into the two clamping surfaces.

[0012] Preferably, the swing edge of the support plate is provided with bolts for insertion into the mating surfaces of the two retaining shells.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting ball bearings, the ball bearings installed in a rolling manner cover and fit the sphere wrapped between the two housings. When the hull slides in a direction parallel to the building surface, the ball bearings ensure that the rubber pad can drive the internal sphere to rotate by the friction between the hull and the rubber pad or by the friction on the building surface. The rolling of the rubber pad can prevent wear on the surface of the rubber pad.

[0015] 2. In this utility model, the ball is set as the support of the center of the rubber pad. When the internal threaded ring is removed, the two clips are rotated to open, which makes it easy to remove the ball when the surface of the rubber pad is worn, thereby realizing the replacement of the rubber pad with severe surface wear.

[0021] 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.

[0022] 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.

[0023] like Figures 1-4 As shown, a collision protection structure for water transportation includes a mounting base 1 for fixed installation on the surface of a ship or building. The mounting base 1 is installed on the surface of the ship or building using reinforced concrete or expansion bolts. A socket 2 is provided on one side of the mounting base 1, and a plug block 3 is inserted into the top edge of the socket 2. A pin 4 is provided between the socket 2 and the plug block 3. In use, the plug block 3 can be pulled out of the socket 2 by removing the pin 4. A connecting plate 5 is fixedly installed on one side of the plug block 3. An energy-absorbing mechanism is provided on one side of the connecting plate 5, and a connecting plate 17 is installed on the connecting plate 5 through the energy-absorbing mechanism. The energy-absorbing mechanism is used to absorb the compressive force. Two symmetrically arranged retaining shells 8 are hinged to the side of the connecting plate 17 facing away from the mounting base 1. A semi-circular ring 9 is fixedly installed on the outer wall of the retaining shell 8. The two semi-circular rings 9 form a complete ring, and the outer walls of the two retaining shells 8 in the combined state are threadedly connected to an internal threaded ring 10. The internal threaded ring 10 helps to ensure that the two retaining shells 8 remain in a stable position. Figure 1The state shown is as follows: A rolling ball 18 is embedded between two retainers 8. The surface of the ball 18 is covered with a rubber pad 11. The inner walls of the two retainers 8 are in clearance fit with the surface of the rubber pad 11, and several rolling balls 12 are embedded in the inner walls of the retainers 8. The ball 18 serves as an internal support, and the surface rubber pad 11 serves as an external support. When the hull contacts the surface of the rubber pad 11, or when the rubber pad 11 moves with the hull and contacts the building surface, the resulting pressure is absorbed by an energy-absorbing mechanism. When the hull slides in a direction parallel to the building surface, the friction between the hull and the rubber pad 11, or the friction on the building surface, ensures that the rubber pad 11 can drive the internal ball 18 to rotate. The rolling of the rubber pad 11 can prevent wear on the surface of the rubber pad 11. In addition, the ball 18 serves as a support for the center of the rubber pad 11. When the internal threaded ring 10 is removed, the two retainers 8 are rotated to open, making it easy to remove the ball 18 when the surface of the rubber pad 11 is worn, thereby realizing the replacement of the rubber pad 11 with severe surface wear.

[0024] Additionally, the energy absorption mechanism includes a main damping spring 13, several first damping springs 6, and several second damping springs 7. The cylinder body and telescopic end of the main damping spring 13 are respectively installed at the center of the connecting plate 5 and the connecting plate 17. The several first damping springs 6 and several second damping springs 7 are arranged in a circular array around the main damping spring 13, with a second damping spring 7 positioned between two adjacent first damping springs 6. An extension seat 16 is fixedly installed on the side of the connecting plate 17 at the position of each second damping spring 7. The cylinder body and telescopic end of the first damping spring 6 are respectively hinged to the connecting plate 5 and the connecting plate 17. On the connecting plate 17, the cylinder body and telescopic end of the second damping spring 7 are respectively hinged to the extension seat 16 and the connecting plate 5. The two adjacent first damping springs 6 and second damping springs 7 are distributed in a cross shape. The main damping spring 13, the first damping springs 6 and the second damping springs 7 can evenly distribute and absorb the generated impact force. Conversely, the first damping springs 6 and the second damping springs 7 can also provide oblique support around the main damping spring 13 to prevent the main damping spring 13 from bending due to the oblique force generated when the hull slides in a direction parallel to the building surface.

[0025] Additionally: Support plates 14 are hinged to the sides of the connecting plate 17 at both ends of the mating surfaces of the two retainers 8. The swinging edges of the support plates 14 are inserted into the mating surfaces of the two retainers 8. Bolts 15 are threaded through the swinging edges of the support plates 14 for insertion into the mating surfaces of the two retainers 8. These bolts 15 connect the support plates 14 to the two closed retainers 8. The internal threaded rings 10 facilitate double reinforcement of the two retainers 8. The additional support plates 14, as shown... Figure 2As shown, it can only swing relative to the fixed base 1, so the position of the two retainers 8 in the combined state can also be fixed in the direction, that is, to prevent the two retainers 8 in the combined state from rotating or swinging.

[0026] Working principle: During use, the ball 18 wrapped with rubber pad 11 is fixed by two retainers 8. The two retainers 8 are further fixed by using internal threaded rings 10 and bolts 15 passing through the support plate 14. Taking fixing the fixing seat 1 to the surface of the ship as an example, the plug 3 is inserted into the socket 2 and fixed with the pin 4. When the ship approaches the port, the ball 18 comes into contact with the port surface. The squeezing and impact forces generated during the contact are absorbed by the energy absorption mechanism. When the ship continues to move forward or backward, the friction force of the rubber pad 11 and the rolling of the ball 12 enable the ball 18 to roll within the two retainers 8.

[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 present utility model.
