Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned monitoring vessel technology, and in particular to an unmanned vessel for monitoring watershed carbon ecological compensation. Background Technology
[0002] Quantifying the carbon sequestration capacity of watershed ecosystems has become a core basis for ecological compensation mechanisms. Soil and water conservation measures (such as terraces, silt-retention dams, and afforestation) significantly increase terrestrial carbon storage through carbon sequestration and erosion reduction. For example, soil and water conservation measures on the Loess Plateau have an average annual carbon sequestration increase of 2.08 million tons of CO2 equivalent and a soil carbon sequestration of 630,000 tons. However, traditional monitoring relies on manual sampling and fixed stations, which suffers from limited coverage, poor data timeliness, high costs, and safety risks, making it difficult to meet the needs of dynamic carbon sequestration assessment.
[0003] Bottlenecks in current unmanned surface vessel (USV) monitoring technology: While current USVs for water environment monitoring can achieve partial automation, they face the following key challenges in carbon monitoring scenarios: Insufficient equipment protection: Spray generated by surface navigation can easily splash into the monitoring module, leading to decreased sensor accuracy or even damage. Existing unmanned surface vessels (USVs) mostly use fixed hulls or simple waterproof covers, failing to balance protective effectiveness with the freedom of gas sampling. Therefore, this paper proposes an USV for watershed carbon ecological compensation monitoring to address these issues. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to propose an unmanned vessel for monitoring watershed carbon ecological compensation, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of the present invention provides an unmanned vessel for monitoring watershed carbon ecological compensation, including a hull, a battery, a drive motor, and a propeller. The battery is installed inside the hull, the drive motor is fixedly connected to the rear of the hull, and the propeller is fixedly connected to the output end of the drive motor. A rudder motor is fixedly connected to the bottom of the hull, and a rudder plate is fixedly connected to the output end of the rudder motor. An antenna module is fixedly connected to the corner of the top surface of the hull, and a monitoring module is fixedly connected to the upper part of the middle of the hull. An electric cylinder is fixedly connected to the edge of the top surface of the hull. A connector is fixedly connected to the output end of the electric cylinder. A baffle is fixedly connected to the inner side of the connector. The baffle has a U-shaped structure and is located above and on both sides of the monitoring module.
[0007] Preferably, in any of the above solutions, the battery supplies power to the drive motor, servo motor, and monitoring module, and the hull is made of stainless steel.
[0008] The above technical solution is adopted as follows: This unmanned surface vessel (USV) has a built-in motherboard connected to a wireless module, which can receive remote control signals. The USV's propulsion source is a drive motor, and the battery provides power to the drive motor. When the drive motor is working, the propeller rotates, causing the vessel to move forward or backward. The output of the servo motor can drive the rudder to swing, thereby turning the vessel.
[0009] During operation, the vessel uses an infrared gas analysis monitoring module for greenhouse gas flux monitoring. The floating chamber method is employed (the monitoring module monitors changes in air concentration above the water surface and calculates the flux) to quantify the emissions of CO2, CH4, and N2O.
[0010] Preferably, in any of the above schemes, the antenna module receives remote control signals.
[0011] The design incorporates a height-adjustable shield structure. When the boat is moving on the water, water splashes from both sides can easily reach the boat. The shield prevents water from splashing onto the monitoring module, providing waterproof protection and reducing data anomaly rates. Made of PE material, the shield does not interfere with the monitoring module's operation. Furthermore, the shield's height is adjustable. When the electric cylinder's output end extends, the shield is raised; when it retracts, the shield is lowered. At higher boat speeds, the shield can be lowered for better protection of the monitoring module; at lower boat speeds, it can be raised to minimize water splashes. The shield height automatically adjusts with boat speed, balancing protective effectiveness with sampling flexibility.
[0012] Preferably, of any of the above schemes, the monitoring module is an infrared gas analysis and monitoring module, and the electric cylinder is installed vertically.
[0013] Device structural design: dynamic splash protection system, with vertical electric cylinders symmetrically mounted on the edge of the top surface of the hull; welded joints at the output end of the electric cylinders; U-shaped baffles riveted to the inside of the joints, made of PE (polyethylene) material.
[0014] The high-precision monitoring unit employs infrared gas analysis technology. It integrates a three-channel synchronous detection sensor for CO2, CH4, and N2O.
[0015] Preferably, in any of the above schemes, the end of the electric cylinder output terminal is welded to the connector, and the connector is riveted to the baffle.
[0016] Preferably, the material of the baffle is PE, and the baffle is liftable.
[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: The unmanned surface vessel (USV) used for carbon ecological compensation monitoring in this watershed features a retractable shield structure. When the vessel is moving on the water, water splashes from the sides can easily reach the vessel. The shield prevents water from splashing onto the monitoring module, providing waterproof protection and reducing data anomaly rates. Made of PE material, the shield does not interfere with the module's operation. The shield's height is adjustable; it rises when the electric cylinder's output is extended and lowers when it retracts. At higher speeds, the shield can be lowered for better protection of the monitoring module, while at lower speeds, it can be raised to minimize water splashes. The shield height automatically adjusts with vessel speed, balancing protective effectiveness with sampling freedom.

[0023] like Figure 1-4 As shown, the unmanned vessel used for carbon ecological compensation monitoring in this watershed includes a hull 1, a battery 2, a drive motor 3, and a propeller 4. The battery 2 is installed inside the hull 1, and the drive motor 3 is fixedly connected to the rear of the hull 1. The output end of the drive motor 3 is fixedly connected to the propeller 4. A rudder motor 5 is fixedly connected to the bottom of the hull 1, and a rudder plate 6 is fixedly connected to the output end of the rudder motor 5. An antenna module 7 is fixedly connected to the corner of the top surface of the hull 1, and a monitoring module 8 is fixedly connected to the upper part of the middle of the hull 1. An electric cylinder 9 is fixedly connected to the edge of the top surface of the hull 1. A connector 10 is fixedly connected to the output end of the electric cylinder 9. A baffle 11 is fixedly connected to the inner side of the connector 10. The baffle 11 has a U-shaped structure and is located above and on both sides of the monitoring module 8.
[0024] Example 1: Battery 2 supplies power to drive motor 3, servo motor 5, and monitoring module 8. The hull 1 is made of stainless steel. Antenna module 7 receives remote control signals. Monitoring module 8 is specifically an infrared gas analysis monitoring module. Electric cylinder 9 is vertically mounted. The output end of electric cylinder 9 is welded to connector 10, and connector 10 is riveted to baffle 11. Baffle 11 is made of PE and is adjustable in height.
[0025] Example 2: This unmanned surface vessel (USV) has a built-in motherboard connected to a wireless module 7, which can receive remote control signals. The USV's propulsion source is a drive motor 3, and the battery 2 provides power to the drive motor 3. When the drive motor 3 is working, the propeller 4 rotates, causing the vessel to move forward or backward. The output of the servo motor 5 can drive the rudder plate 6 to swing, thereby turning the vessel.
[0026] During operation, the vessel uses monitoring module 8, an infrared gas analysis monitoring module, to monitor greenhouse gas fluxes. The floating chamber method is used (monitoring module 8 monitors changes in air concentration on the water surface and calculates the flux) to quantify the emissions of CO2, CH4, and N2O.
[0027] Device structure design: dynamic splash protection system, four vertical electric cylinders 9 are symmetrically installed on the top edge of the hull 1; the output end of the electric cylinder 9 is welded with a joint 10; the inner side of the joint 10 is riveted with a U-shaped baffle 11, which is made of PE (polyethylene).
[0028] The high-precision monitoring unit, monitoring module 8, employs infrared gas analysis technology. It integrates a three-channel synchronous detection sensor for CO2, CH4, and N2O.
[0029] The working principle of this utility model is as follows: The unmanned surface vessel (USV) navigates along a preset path to perform monitoring tasks: During the travel control phase, battery 2 supplies power to drive motor 3 → propeller 4 rotates to generate thrust. Remote control commands are transmitted via antenna module 7 → servo motor 5 drives rudder 6 to deflect (±30°) and adjust the course. Gas monitoring phase: Static drift mode: Ship speed drops to 0.2m / s, shield 11 rises to its highest position. Floating chamber method operation: Monitoring module 8 continuously collects headspace gas at a depth of 10cm above the water surface → analyzes the changes in CO2 / CH4 / N2O concentration gradients → calculates gas flux through concentration time-varying rate.
[0030] During the dynamic protection phase, when the wave height is greater than 5cm or the boat speed is greater than 1m / s: the electric cylinder 9 retracts to lower the shield 11 → the U-shaped structure surrounds the monitoring module 8 on the left, right and top → the PE material blocks more than 80% of the splashing water (the light transmittance is greater than 90% and does not affect the infrared measurement).
[0031] When cruising at low speed in calm waters: Electric cylinder 9 lifts shield 11 → Opens the monitoring environment and expands the sampling range.
[0032] Compared with the prior art, the present invention has the following advantages: The unmanned surface vessel (USV) used for monitoring carbon ecological compensation in this watershed is designed with a height-adjustable shield 11. When the vessel is moving on the water, water splashes from both sides can easily reach the vessel. The shield 11 prevents water from splashing onto the monitoring module 8, providing waterproof protection and reducing its data anomaly rate. Made of PE material, the shield 11 does not affect the operation of the monitoring module 8. Furthermore, the height of the shield 11 is adjustable. When the output end of the electric cylinder 9 extends, the shield 11 is raised; when the output end of the electric cylinder 9 retracts, the shield 11 is lowered. At high vessel speeds, the shield 11 can be lowered to better protect the monitoring module 8; at low vessel speeds, the shield 11 can be raised, at which point there is virtually no water splashing. The height of the shield 11 automatically adjusts with the vessel speed, balancing protective effectiveness with sampling freedom.
