Description

Technical Field

[0001] The invention relates to the technical field of forestry carbon sink monitoring, and in particular to monitoring equipment used for forestry carbon sink projects. Background Art

[0002] Carbon sink is the process, activity, and mechanism of reducing carbon dioxide from the atmosphere. It is generally used to describe the amount or ability to absorb and store carbon dioxide in the atmosphere through artificial measures such as afforestation and vegetation restoration. It also includes the contribution of grasslands, wetlands, oceans and other ecosystems to carbon absorption, as well as the maintenance of carbon storage and carbon fixation by soil and permafrost; and forestry carbon sink is the largest carbon reservoir in terrestrial ecosystems, and forest carbon sink has unique advantages. According to the results of the 2020 Global Forest Resources Assessment of the Food and Agriculture Organization of the United Nations, the carbon storage of global forests accounts for about 77% of the global vegetation carbon storage, and the carbon storage of forest soil accounts for about 39% of the global soil carbon storage. It is estimated that each acre of forest land can generate carbon sinks of about 1 ton / year. Therefore, compared with industrial carbon capture and emission reduction, forest carbon sink has the remarkable characteristics of low cost, easy implementation, and other ecological benefits. It is currently one of the most economical, safe and effective means of carbon fixation and sink.

[0003] In the prior art, a Chinese patent document with a publication number of CN218455690U proposes a carbon sink monitoring device, including a carbon sink monitoring device, a mounting plate fixedly connected to the carbon sink monitoring device, a photovoltaic panel mounted on the mounting plate, a water tank fixedly connected to the carbon sink monitoring device, two side panels fixedly connected to the top surface of the mounting plate, a driving assembly and a cleaning assembly cooperating with each other are arranged on the mounting plate, and a water spray assembly is also arranged on the mounting plate. The above scheme can clean the photovoltaic panel regularly to avoid the hot spot phenomenon of the photovoltaic panel, ensure the normal power supply of the photovoltaic panel to the monitoring device, and then ensure the normal operation of the carbon sink monitoring device. However, in actual use, the existing carbon sink monitoring device is usually fixedly installed, and the monitoring angle cannot be adjusted, or the angle can be adjusted by a motor, but the power source comes from the solar panel, which results in the need for a large area of ​​solar panels to provide power, but this requires a large amount of space, resulting in inconvenience in use and transportation.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a monitoring device for forestry carbon sink projects, which has the following beneficial effects:

[0019] 1. The monitoring equipment for forestry carbon sink projects, when the detector body is monitoring, the surface of the evaporation box is coated with black, which can accelerate the absorption of external heat, thereby evaporating the liquid in the evaporation box. The liquid in the evaporation box can be water, which improves the convenience of using the equipment. The liquid in the evaporation box evaporates and rises. When the evaporated liquid contacts the condensation plate on the inner wall of the top of the evaporation box, the liquid condenses to form small water droplets. The condensed small water droplets are gathered together through the guide grooves provided on the guide plate, and the water droplets are guided to drip into the turning table through the guide grooves. When the water droplets drip into the turning table, the weight of the two ends of the turning table is different due to the water droplets, which will cause the turning table to rotate to one side around the axis of the second connecting rod. As the weight of one side of the turning table gradually increases, the second connecting rod can drive the driving half gear to rotate continuously to one side. At the same time, the driving half gear is meshed with the synchronous gear, so that the synchronous gear rotates at the same time, so that the angle of the detector body is adjusted during the monitoring process. Compared with the prior art, it does not need to be driven by additional energy, which reduces the weight of the monitoring equipment and increases the scope of use.

[0020] 2. The monitoring equipment for forestry carbon sink projects, when the liquid on one side of the turning table gradually increases, the buoyancy of the floating ball on one side of the turning table increases, which can drive the first moving rod and the second moving rod to move to one side at the same time, and then drive the synchronous rod to rotate around the axis of the rotating shaft. At this time, the push rod can move in the opposite direction under the drive of the synchronous rod. When the push rod moves to one side, it can drive the trigger head to approach the inner wall of the turning table. When the trigger head enters the flow hole, the guide rod contacts the guide groove and bends to one side through the guide groove. The guide rod is adapted to the guide groove, which can drive the trigger head to rotate, so that when the trigger head moves in the flow hole, it can realize rotation. When the cam is in contact with the first and second limit plates, the liquid in the overturning table can flow out into the evaporator box, thereby completing the recycling of the liquid. At the same time, after the liquid on one side of the overturning table flows out, the buoyancy of the floating ball changes, causing the first moving rod and the second moving rod to move in opposite directions, thereby driving the push rod to reset. At the same time, the push rod achieves an auxiliary reset effect under the elastic force of the reset spring, and the overturning table resets in the opposite direction. At this time, the detector body can be driven to deflect in the opposite direction for monitoring, thereby realizing periodic monitoring and effectively improving the monitoring effect.

[0021] 3. When installing the monitoring equipment for forestry carbon sink projects, the handle is pulled to ensure the accuracy of the installation position. The deflection arm is rotated around the axis of the support rod to achieve installation of the equipment. The buffer block can reduce the impact force when the equipment is adjusted. At the same time, the rotating rod is rotated to engage with the adjustment plate thread, and then the angle of the deflection arm is adjusted to ensure the stability of the equipment during installation. The handle further improves the operability of the equipment and is suitable for rapid installation and adjustment under different conditions. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a monitoring device for forestry carbon sink projects.

[0037] When the equipment is running, the adjustment component periodically drives the synchronous gear 5, thereby driving the angle of the detector body 6 to be adjusted, ensuring that the detector body 6 can achieve monitoring of different angles and ranges during the monitoring process. The baffle plate 7 is used to prevent the external environment from interfering with the detector body 6. The cooperation between the mounting plate 2 and the mounting component realizes the stable installation of the equipment. The angle of the detector body 6 is automatically adjusted by the adjustment component to ensure the accuracy and continuity of the monitoring data. The mounting component simplifies the installation process of the equipment and increases the stability of the equipment. Compared with the existing technology, it improves the convenience of use, does not require increased energy consumption, and increases the service life of the equipment.

[0038] As a preferred implementation in this embodiment, refer to the attached Figure 1-Figure 10A condensation plate 8 is arranged on the inner wall of the evaporation box 3, a guide plate 9 is arranged at the bottom of the condensation plate 8, the guide plate 9 is arranged to be inclined to one side, a guide groove 10 is opened on the top surface of the guide plate 9, and the guide groove 10 is an arc-shaped arc bent to one side, and the condensation plate 8 is arranged on the top of the turning table 11; the adjustment component includes a second connecting rod 40 arranged on the inner wall of the evaporation box 3, a driving half gear 41 is arranged on the second connecting rod 40, and the driving half gear 41 is meshed with the synchronous gear 5, and a center plate 12 is fixedly arranged on the second connecting rod 40, and the center plate 12 A turning platform 11 is arranged on both sides of the evaporation box 3, the bottom length of the evaporation box 3 is a trapezoidal structure with a greater bottom length than the top length, and the heights of the two ends of the turning platform 11 are greater than the height of the middle of the turning platform 11; a first moving rod 13 and a second moving rod 14 are slidably penetrated in the center plate 12, and the first moving rod 13 and the second moving rod 14 are symmetrically distributed, and floating balls 20 are arranged at both ends of the first moving rod 13 and the second moving rod 14, a pushing rod 15 is slidably penetrated in the center plate 12, and a rotating shaft 19 is rotatably arranged on the turning platform 11, and a synchronous The synchronous rod 18 is a telescopic structure, one end of the synchronous rod 18 is rotatably arranged in the first moving rod 13 or the second moving rod 14, and the other end of the push rod 15 is arranged in the push rod 15; a limit ring 16 is arranged on the push rod 15, one end of the push rod 15 is sleeved with a return spring 17, one end of the return spring 17 is fixedly arranged on one side of the center plate 12, and the other end of the return spring 17 is fixedly arranged on one side of the limit ring 16; a trigger head 21 is rotatably arranged on the top of the push rod 15, and a trigger head 21 is provided on the surface of the trigger head 21. The guide groove 25 is bent to one side; the trigger head 21 is provided with a first limit plate 22 and a second limit plate 23, and the first limit plate 22 and the second limit plate 23 are both provided with through grooves 24, and the through grooves 24 are symmetrically distributed on the first limit plate 22 and the second limit plate 23; both ends of the turning table 11 are provided with flow holes 26, and a group of flow grooves 27 are provided inside the flow hole 26, and the flow grooves 27 are adapted to the width of the through grooves 24; a guide rod 28 is provided inside the flow hole 26, and the guide rod 28 is adapted to the guide groove 25;

[0039] When the detector body 6 is monitoring, the surface of the evaporation box 3 is coated with black, which can accelerate the absorption of external heat, thereby evaporating the liquid in the evaporation box 3. The liquid in the evaporation box 3 can be water, which improves the convenience of using the device. The liquid in the evaporation box 3 evaporates and rises. When the evaporated liquid contacts the condensation plate 8 on the top inner wall of the evaporation box 3, the liquid condenses to form small water droplets. The guide groove 10 provided on the guide plate 9 gathers the condensed small water droplets together. At the same time, the guide groove 10 guides the water droplets to drip onto the turning table 11. When the water droplets drip onto the turning table 11, When the weight of the two ends of the flip table 11 is different due to the water droplets, the flip table 11 will rotate to one side around the axis of the second connecting rod 40. As the weight of one side of the flip table 11 gradually increases, the second connecting rod 40 can drive the driving half gear 41 to continuously rotate to one side. At the same time, the driving half gear 41 is meshed with the synchronous gear 5, so that the synchronous gear 5 rotates at the same time, thereby adjusting the angle of the detector body 6 during the monitoring process. Compared with the prior art, there is no need to drive it with additional energy, which reduces the weight of the monitoring equipment and increases the scope of use.

[0040] When the liquid on one side of the flip table 11 gradually increases, the buoyancy of the floating ball 20 on one side of the flip table 11 increases, which can drive the first moving rod 13 and the second moving rod 14 to move to one side at the same time, and then drive the synchronous rod 18 to rotate around the axis of the rotating shaft 19. At this time, the push rod 15 can move in the opposite direction under the drive of the synchronous rod 18. When the push rod 15 moves to one side, it can drive the trigger head 21 to approach the inner wall of the flip table 11. When the trigger head 21 enters the circulation hole 26, the guide rod 28 contacts the guide groove 25. The guide groove 25 bends to one side, and the guide rod 28 is adapted to the guide groove 25, which can drive the trigger head 21 to rotate, so as to achieve the effect of rotation when the trigger head 21 moves in the circulation hole 26. When the trigger head 21 rotates, the through grooves 24 on the first limit plate 22 and the second limit plate 23 can contact the flow grooves 27 in the flow hole 26. When the through grooves 24 contact the flow grooves 27, the liquid in the turning table 11 can flow out to the evaporator 3, thereby completing the recycling of the liquid. At the same time, after the liquid on one side of the turning table 11 flows out, the buoyancy of the floating ball 20 changes, causing the first moving rod 13 and the second moving rod 14 to move in opposite directions, thereby driving the push rod 15 to reset. At the same time, the push rod 15 achieves an auxiliary reset effect under the elastic force of the reset spring 17, and the turning table 11 resets in the opposite direction. At this time, the detector body 6 can be driven to deflect in the opposite direction for monitoring, thereby realizing periodic monitoring and effectively improving the monitoring effect.
