Description

Technical Field

[0001] The present application relates to the technical field of buoys, and in particular to an underwater wireless timing transmission device. Background Art

[0002] As the world pays more and more attention to the ocean, especially in key areas such as marine environmental protection, resource development and utilization, national security, and marine meteorological forecasting and disaster prevention, in-depth understanding and continuous monitoring of the underwater environment have become an urgent need. In this context, it is particularly important to use advanced buoy technology for long-term, continuous, and multi-factor hydrological data monitoring. Such monitoring devices usually integrate a variety of sensors and communication technologies, and can automatically and in real time collect and transmit a large amount of hydrological and meteorological data, including but not limited to water temperature, salinity, flow rate, flow direction, dissolved oxygen, turbidity, current profiles, marine ecological parameters (such as primary productivity reflected by chlorophyll a concentration) and meteorological parameters (such as wind speed, wind direction, air pressure, humidity, etc.). Through these data, researchers and decision makers can accurately assess the marine ecological environment: long-term monitoring of water quality and ecological parameters, timely detection of environmental pollution problems, assessment of the health of marine ecological devices, and provide a scientific basis for marine ecological protection and restoration. At the same time, by mastering the ocean hydrological characteristics, it provides detailed data support for fishery resource management, marine energy development (such as wind energy, wave energy), marine mineral resource exploration, etc., and promotes the rational and sustainable development of resources.

[0003] With the advancement of technology and the increase in application needs, the challenges faced by existing buoy devices in data transmission have become increasingly prominent. In traditional buoy design, in order to achieve direct communication with satellites, the antenna assembly must be placed above the water surface to ensure unimpeded transmission of signals. Although this design ensures the continuity and stability of data return, it also brings a series of problems. The most significant disadvantage is that it significantly reduces the concealment of the buoy. The exposed antenna becomes an easily identifiable target. It is not only vulnerable to damage from natural environmental factors (such as storms and wave impacts), but also faces the risk of human damage, such as accidental collisions, malicious damage or illegal interference, which will seriously affect the data collection and transmission capabilities of the buoy, and even lead to the paralysis of the entire monitoring network. Utility Model Content

[0004] This device provides an underwater wireless timing transmission device, and the specific implementation is as follows:

[0005] An underwater wireless timing transmission device, comprising:

[0006] A floating platform, the floating platform is connected to a counterweight block through a cable, a detection instrument is integrated on the floating platform, and the floating platform is buried underwater through the counterweight block;

[0007] The controller and the release component are arranged on the floating platform. The output end of the release component is provided with a communication buoy. The controller is electrically connected to the release component to trigger it to release the communication buoy for remote transmission of monitoring data.

[0008] Based on the above technical solutions, compared with traditional surface buoy monitoring devices, this design significantly enhances the concealment and safety of the device by removing obvious water markers. In marine observation and research activities, this stealth design can reduce the risk of interference by human damage or natural factors. Without conspicuous water structures, the device can continue to collect data without attracting attention, providing a valuable source of information for scientific researchers and decision makers. As for underwater monitoring methods such as submerged buoys, this device has achieved a real-time leap in data transmission through an innovative communication buoy timed release mechanism. In the past, the acquisition of underwater monitoring data usually relied on the regular recovery of submerged buoys or the use of wired transmission. This method is not only limited by long recovery cycles and high operating costs, but also difficult to achieve real-time data updates.

[0009] Preferably, the floating platform comprises an annular frame filled with buoyancy blocks, and the communication buoy comprises a first shell with a side filled with a floating body, and a communication antenna is installed on the top of the first shell.

[0010] Based on the above technical solution, the buoyancy block of the communication buoy is made of buoyant material, and the center of gravity is located at the bottom, so as to maintain a stable posture and the direction of the satellite antenna after leaving the water; when the release component receives the release command from the controller, it executes the release action, pushes away and releases the communication buoy, and the communication buoy floats to the sea surface under the action of its own buoyancy. During this process, the controller can be set to trigger the release component with a regular signal, such as once a month.

[0011] Preferably, a plurality of mounting hoops are provided along the circumference of the bottom of the floating platform, and each mounting hoops is connected to the cable at multiple points.

[0012] Based on the above technical solution, by evenly installing multiple clamps around the middle of the floating platform and connecting cables to fixed points or anchor points, the tension acting on the floating platform can be evenly distributed. This layout avoids excessive force on a single point and reduces local stress concentration, thereby improving the stability and durability of the overall structure. The marine environment is complex and changeable, and external forces such as wind, waves, and currents can easily cause the floating platform to tilt or move. The mesh support structure formed by multiple clamps and cables can effectively resist these external forces, keep the platform's posture horizontal, and ensure the safety of operations on the platform and the normal operation of equipment.

[0013] Preferably, the release assembly includes a driving structure, a lifting cylinder and a wire-releasing structure equipped with a pull rope, the wire-releasing structure includes a third shell, inside of which a wire-releasing cylinder with a pull rope wound therein is rotatably provided, and the end of the pull rope is connected to the first shell.

[0014] Based on the above technical solution, the pull rope can be built with a communication cable, that is, the controller and the communication buoy are wired during remote communication to improve the stability of communication information.

[0015] Preferably, the rope-releasing drum is coaxially and integrally provided with a rope-releasing shaft, an axial sliding sleeve at the end of the rope-releasing shaft is provided with a lifting cylinder, and an anti-turnover structure is provided between the two.

[0016] Preferably, it also includes a top plate arranged at the end of the motor, the lifting cylinder is connected to the driving structure, and the top plate is provided with a vertical through hole for the lifting cylinder to slide through.

[0017] Preferably, the lifting cylinder is provided with a plurality of elastic balls along its circumference, the vertical through hole is provided with clamping grooves and annular grooves in sequence along its length direction, and the clamping groove is composed of spherical grooves of the same number as the elastic balls equidistantly arranged along the circumference of the vertical through hole.

[0018] Based on the above technical solution, an elastic ball is embedded inside the lifting cylinder, and the lifting cylinder and the elastic ball are controlled to move axially between the annular groove and the spherical groove through a lifting drive structure to complete the conversion of the line-releasing and locking functions, and the releasing length of the communication buoy is controllable; when the buoy needs to be abandoned, the lifting cylinder continues to move upward and then removes the wire, completely separating the connection between the communication buoy and the floating platform, thereby realizing the abandonment of the communication buoy.

[0019] Preferably, a power supply is provided in the floating platform, and the power supply is electrically connected to the controller, the detection instrument and the driving structure.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. Compared with the currently commonly used surface buoy monitoring, the utility model can effectively improve the safety of the device because there is no obvious water marker. Compared with underwater monitoring such as submerged buoys, the communication buoy can be released regularly, and the underwater monitoring data can be transmitted to the shore-based terminal via satellite communication in real time, which effectively improves the timeliness of the data;

[0022] 2. The buoyancy block of the communication buoy in the utility model is made of buoyancy material, and the center of gravity is located at the bottom, so as to maintain a stable posture and the direction of the satellite antenna after leaving the water;

[0023] 3. The utility model has a simple structure. The release component utilizes the alternating cooperation of the annular groove and the spherical groove with the elastic ball in the lifting cylinder, so that the lifting cylinder can realize the switching between the locking and releasing of the communication buoy. In addition, the communication buoy can be completely abandoned after the communication is completed by utilizing the thread removal after the thread connection. BRIEF DESCRIPTION OF THE DRAWINGS
