Description

Technical Field

[0001] The utility model relates to the field of marine navigation equipment, in particular to a socket-connected tail pipe of a light buoy. Background Art

[0002] Light buoys are important equipment for navigation marks to function and are widely used in sea areas. The main functions of light buoys are to mark waterways, warn of dangerous areas, etc., to ensure the safety of ships' navigation. In the prior art, light buoys are mainly composed of floats, tail pipes, and weights. The tail pipe, as a key part connecting the float and the weight, is subjected to complex forces from the marine environment, such as wave impact, seawater corrosion, etc., which are very easy to cause rust and damage. For a long time, although the main structure of the buoy has been kept in good condition due to the use of corrosion-resistant materials or coating treatment, the end part of the tail pipe has direct contact with the weight and the existence of gaps, resulting in long-term friction between the steel plates, causing wear and thinning of the steel plate, thus becoming a severely affected area of ​​rust and damage. For such buoys with serious rust and damage to the tail pipe, it would be a pity to replace the entire buoy, resulting in huge waste of resources and economic costs. If it continues to be used, there is a risk of breakage, which causes the weight to fall off and the light buoy loses stability. Therefore, in view of the above technical problems, this application makes improvements. Utility Model Content

[0004] The technical solution of the utility model is achieved as follows: a socket-connected light buoy tail pipe comprises a detachably connected tail pipe upper section and a tail pipe lower section, the tail pipe upper section and the tail pipe lower section are connected by a socket connection, and a plurality of weights are arranged on the tail pipe lower section.

[0005] Preferably, an upper fixing flange is integrally formed at the lower end of the upper section of the tail pipe, and a lower fixing flange is integrally formed at the upper end of the lower section of the tail pipe. After the upper section of the tail pipe and the lower section of the tail pipe are socket-connected, the upper fixing flange fits with the lower fixing flange, and the upper fixing flange and the lower fixing flange are fixed by bolts.

[0006] Preferably, the lower section of the tail pipe includes a socket section, the socket section is located on the upper side of the lower fixed flange, and the socket section is used to be tightly inserted into the upper section of the tail pipe.

[0007] Preferably, a sealing ring is provided at the socket connection position between the tail pipe upper section and the tail pipe lower section, and a sealing ring is provided between the upper fixed flange and the lower fixed flange.

[0008] Preferably, the inner and outer surfaces of the tail pipe upper section and the tail pipe lower section are sprayed with a spray-coated corrosion-resistant coating.

The utility model designs the tail pipe of the buoy as a detachably connected tail pipe upper section and tail pipe lower section, the tail pipe upper section and tail pipe lower section are tightly connected by a socket connection, and the tail pipe lower section is connected to a pressure iron. Therefore, when the tail pipe lower section is severely corroded, only the tail pipe lower section can be replaced without replacing the entire tail pipe or buoy, thus avoiding the scrapping of the entire buoy due to local corrosion, significantly extending the service life of the buoy, greatly reducing material consumption and replacement costs, and reducing the difficulty and time of maintenance.

[0013] 2. The upper section and the lower section of the stern tube are provided with a sealing structure at the socket connection to ensure good sealing at the connection to prevent seawater from infiltrating and aggravating corrosion. At the same time, the inner and outer surfaces of the upper section and the lower section of the stern tube are sprayed with a spray-corrosion-resistant coating, which further improves the corrosion resistance of the stern tube and ensures navigation safety.

[0014] 3. A gasket ring is fixedly arranged on the inner side of the weight iron and located between the weight iron and the lower section of the tail pipe. The setting of the gasket ring can reduce the friction of the weight iron on the lower section of the tail pipe. In addition, the gasket ring is also used to reduce the gap between the weight iron and the lower section of the tail pipe. The anti-sway rubber stripes limit the shaking of the gasket ring relative to the lower section of the tail pipe, which is conducive to maintaining the stability of the weight iron setting and reducing the intrusion of seawater between the weight iron and the lower section of the tail pipe.

[0015] 4. The upper section of the tail pipe and the lower section of the tail pipe are also bolted together by an upper fixing flange and a lower fixing flange, and standardized connectors are used to facilitate disassembly and assembly, thereby reducing maintenance costs and time.

When the utility model is in use, the buoy 6 is located on the water surface, and the tail pipe is fixed at the bottom of the buoy 6, that is, underwater, and the weights 3 on the tail pipe ensure the stability and reliability of the buoy on the water surface. In addition, according to the use environment, an anchor and an anchor chain can be equipped, one end of the anchor chain is connected to the tail pipe lower section 2, and the other end is connected to the anchor, the anchor sinks to the seabed, and the buoy is fixed at a predetermined position by the anchor chain. The utility model designs the tail pipe of the buoy as a detachably connected tail pipe upper section 1 and a tail pipe lower section 2, the tail pipe upper section 1 and the tail pipe lower section 2 are tightly connected by a socket-connected manner, and the tail pipe lower section 2 is connected to the weights 3. Therefore, when the lower section 2 of the tail pipe is severely corroded, only the lower section 2 of the tail pipe can be replaced without replacing the entire tail pipe or the buoy 6, thereby avoiding the scrapping of the entire buoy 6 due to local corrosion, significantly extending the service life of the buoy, greatly reducing material consumption and replacement costs, and reducing maintenance difficulty and time.

[0026] Furthermore, in order to enhance the connection firmness between the tail pipe upper section 1 and the tail pipe lower section 2 and facilitate disassembly and assembly, an upper fixing flange 11 is integrally formed at the lower end of the tail pipe upper section 1, and a lower fixing flange 21 is integrally formed at the upper end of the tail pipe lower section 2. After the tail pipe upper section 1 and the tail pipe lower section 2 are socket-connected, the upper fixing flange 11 fits with the lower fixing flange 21, and the upper fixing flange 11 and the lower fixing flange 21 are fixed by bolts.

[0027] In this embodiment, the specific structure of the socket connection between the liner upper section 1 and the liner lower section 2 is as follows: the liner lower section 2 includes a socket section 22, which is located on the upper side of the lower fixed flange 21, and is used to be tightly inserted into the liner upper section 1. In order to ensure that the connection between the liner upper section 1 and the liner lower section 2 is well sealed and prevent seawater from infiltrating and aggravating corrosion, a sealing ring 41 is provided at the socket connection position of the liner upper section 1 and the liner lower section 2, and a sealing ring 42 is provided between the upper fixed flange 11 and the lower fixed flange 21.
