Description

Technical Field

[0001] This utility model relates to the field of immersed tube construction technology, specifically a positioning buoy for underwater immersed tubes. Background Technology

[0002] Immersed tunnel sections are widely used in key areas such as the Bahe River waterway. These tunnel sections are not only long and made of special materials, but also face complex construction environments, posing significant challenges to positioning. Traditional positioning methods, such as sonar detection and underwater divers, are not only inefficient but also highly susceptible to environmental factors, such as water flow speed and water clarity, which can all affect the accuracy of positioning.

[0003] With the continuous development of positioning technology, satellite positioning systems such as GPS and BeiDou have been widely used in various fields. However, in underwater environments, the positioning accuracy and reliability of these systems are affected by signal attenuation and interference. Therefore, how to achieve high-precision and high-reliability positioning in underwater environments has become an urgent problem to be solved.

[0004] Buoys, as a common positioning device, have been widely used in oceans, lakes, and other water bodies. However, traditional buoys often have limited functionality, providing only approximate location information, and cannot meet the high precision and high reliability requirements for underwater submerged pipe positioning. Utility Model Content

[0005] The present invention aims to overcome the defects of the prior art and provide a positioning buoy for underwater submerged pipes, which solves the problem that the location of the submerged pipes cannot be found in a timely manner when they are buried underwater during regular maintenance.

[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0007] A positioning buoy for an underwater submerged pipe, characterized in that it comprises:

[0008] The buoy body is made of corrosion-resistant material and is designed to float on the water surface;

[0009] The anti-collision mechanism, located on the outside of the buoy body, is used to reduce the impact force on the buoy;

[0010] A sealing mechanism, located at the top of the buoy body, is used to prevent water from entering the buoy's interior;

[0011] The positioning and indication mechanism, located inside the buoy body, is used to determine the position of the submerged tube and provide indication at night;

[0012] The connecting mechanism is used to connect the buoy to the submerged tube.

[0013] The positioning buoy for an underwater submerged pipe, characterized in that the anti-collision mechanism includes:

[0014] A buffer spring, one end of which is fixed to the outside of the buoy body;

[0015] The buffer plate, fixed to the other end of the buffer spring, is used to compress the buffer spring and reduce the impact force when it is hit.

[0016] The positioning buoy for an underwater submerged pipe, characterized in that the sealing mechanism includes:

[0017] The detachable cover plate achieves a sealed connection through a threaded groove that engages with the threaded top of the buoy body;

[0018] A sealing gasket, placed at the bottom of the cover plate, is used to achieve a preliminary seal;

[0019] An airbag is located at the bottom of the threaded groove. When the cover plate rotates and descends, the sealing gasket compresses the airbag, causing it to expand to both sides, further filling the gap between the cover plate and the threaded groove, and enhancing the sealing effect.

[0020] The positioning buoy for an underwater submerged pipe, characterized in that the positioning and indicating mechanism includes:

[0021] The positioning system, located inside the buoy body, is used to receive satellite signals to determine the buoy's position;

[0022] The light tube is located inside the buoy body and is turned on by a remote controller, emitting red light for nighttime indication.

[0023] The controller connects to the positioning system and the lamps to control their operation.

[0024] The positioning buoy for an underwater submerged pipe, characterized in that the connecting mechanism includes:

[0025] The nylon rope is connected at one end to the buoy body and at the other end to the sinking tube.

[0026] A foam board is placed at the bottom of the buoy body, allowing the buoy to float on the water surface.

[0027] The positioning buoy for an underwater submerged pipe is characterized in that: the buoy body is further provided with a vibration damping plate, which is cylindrical, and the inner wall of the buoy body is connected by a transmission block to further reduce vibration damage.

[0028] The positioning buoy for an underwater submerged pipe is characterized in that: the buoy body is further provided with drying particles to absorb water vapor and keep the inside of the buoy body dry.

[0029] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a positioning buoy for underwater submerged pipes, which can obtain the buoy's position information in real time, thereby determining the approximate position of the submerged pipe, solving the problem of underwater submerged pipes being difficult to locate quickly, and improving maintenance efficiency.

[0030] First, the sealing and drying design significantly improves the buoy's durability. Multiple seals are achieved through the sealing gasket at the bottom of the cover and the expansion of the air bladder at the bottom of the groove, effectively preventing moisture from entering the buoy and thus extending its lifespan. Simultaneously, the drying particles inside the buoy absorb moisture, keeping the interior dry and further ensuring the reliability of the electronic components.

[0031] Secondly, the anti-collision and cushioning design enhances the buoy's stability in complex environments. The external anti-collision mechanism, including buffer springs and buffer plates, effectively reduces impact force when the buoy is struck. Furthermore, internal vibration damping plates further reduce vibration damage, improving the buoy's durability in harsh environments.

[0032] Furthermore, precise positioning and nighttime operation support greatly facilitate maintenance work. The buoy uses the BeiDou positioning system, which can accurately determine the location of the immersed tube, providing maintenance personnel with reliable positioning information. At night or in low visibility conditions, workers can use a remote controller to turn on the lights, emitting red light for indication, ensuring that the buoy can be quickly located, thus supporting nighttime operations.

[0033] In addition, the buoys are made of corrosion-resistant materials, which increases their service life in the water and reduces maintenance and replacement costs due to corrosion.

[0034] Finally, the quick-assembly and convenient maintenance design reduces the difficulty and cost of buoy maintenance. The buoy features a removable cover at the top, which can be quickly installed and removed by rotating it, significantly improving efficiency compared to traditional bolted connections. This design also facilitates the replacement or repair of internal electronic components, reducing maintenance costs and time. Attached Figure Description

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0042] like Figure 1-5 As shown: A positioning buoy for an underwater submerged pipe has a detachable cover plate 6 on top of the buoy 1, facilitating the replacement or maintenance of internal electronic components. The cover plate 6 and the buoy 1 can achieve a sealed connection. Before the buoy 1 is placed in the water, the bottom of the cover plate 6 needs to be placed inside the groove 10, and then the cover plate 6 is manually rotated. The connection between the cover plate 6 and the buoy 1 is achieved through the cooperation of the threaded groove 11 and the thread 7. The sealing gasket 9 at the bottom of the cover plate 6 can achieve the initial seal. At the same time, when the cover plate 6 rotates and descends, the sealing gasket 9 will press against the bottom of the groove 10. The air bladder 19 in the part expands to both sides of the groove 10 when compressed, which helps to fill the gap at the connection between the cover plate 6 and the groove 10, further achieving a seal. This sealing design prevents water from entering the buoy 1, increasing its service life. Furthermore, the drying particles 16 absorb moisture, keeping the inside of the buoy 1 dry. The buoy 1 is connected to the sinking pipe by a nylon rope 18. The nylon rope 18 is wear-resistant, has high tensile strength, and is aging-resistant. It is also water-resistant and can be submerged in water for extended periods. The buoy 1 is then submerged... The foam plate 17 floats on the water surface. When a boat or a large fish hits the buoy 1, the anti-collision mechanism can reduce the damage to the buoy 1. When the buoy 1 is hit, the buffer plate 3 will be hit first. Then the buffer plate 3 will retreat and compress the buffer spring 2. The buffer and rebound of the buffer spring 2 will reduce the impact force on the buoy 1. Then the remaining impact force will be transmitted to the vibration damping plate 4 through the transmission block 5. Then the vibration damping plate 4 will further reduce the vibration damage caused by the impact. The above operation will maximize the protection of the buoy 1. The lamp tube 13, positioning system 14 and controller 15 are installed on the inner wall 12 of the vibration damping plate. The positioning system 14 can be Beidou positioning. The positioning system 14 can determine a large area of ​​the immersed tube. When working at night, the worker remotely controls the controller 15. Then the controller 15 controls the lamp tube 13 to turn on. When the lamp tube 13 is turned on, it emits red light. The cover plate 6 is transparent and will not obstruct the light. The emitted red light can attract maintenance personnel. Then the maintenance personnel will quickly find the buoy 1 by following the red light, thus giving an accurate location of the immersed tube in a large area.

[0043] The buoy is equipped with a BeiDou positioning system, which can acquire the buoy's position information in real time and transmit it wirelessly to maintenance personnel, thereby determining the approximate location of the submerged tunnel. This function solves the problem of the difficulty in quickly locating underwater submerged tunnels and improves maintenance efficiency.

[0044] The cover plate is manually rotated to connect to the buoy via the engagement of the threaded grooves and threads. A sealing gasket at the bottom of the cover plate provides an initial seal. As the cover plate rotates and descends, the gasket compresses the air bladder, causing it to expand laterally and effectively fill the gap between the cover plate and the groove, further enhancing the seal. This sealing design prevents moisture from entering the buoy, extending its lifespan, while the drying particles absorb moisture, ensuring the interior remains dry.

[0045] The buoy is equipped with a light tube, which workers activate via remote control, emitting a red light. Red light travels a long distance in water with good directionality and strong penetrating power, and is not easily interfered with by other light sources, ensuring the buoy can be quickly located even at night or in low visibility conditions. The transparent cover does not obstruct the emission of red light, allowing maintenance personnel to quickly locate the buoy and thus provide accurate positional indication for the submerged tunnel section.

[0046] When the buoy is impacted, the buffer plate is the first to be affected and retracts, compressing the buffer spring. This spring, the buffer spring's cushioning and rebound properties reduce the impact force on the buoy. The remaining impact force is transmitted to the vibration damping plate through the transmission block, further reducing vibration damage and protecting the buoy's internal electronic components.

[0047] The buoy's unique features are mainly reflected in the following aspects: It employs a multi-layered sealing and drying design to ensure the long-term reliability of its internal electronic components; it utilizes anti-collision and cushioning designs to enhance its durability in complex environments; it combines BeiDou positioning with red light indication, as red light has strong penetrating power in water and is less susceptible to interference from other light sources, ensuring the buoy can still be quickly located at night or in low visibility conditions, achieving precise positioning and supporting nighttime operations; the buoy is made of corrosion-resistant materials to extend its lifespan in water; and the cover plate can be quickly disassembled and assembled via rotation, improving efficiency compared to traditional bolted connections. Disassembly of the cover plate allows for inspection of internal electronic components, and the rotating connection of the cover plate ensures a tight seal.

[0048] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
