Description

Technical Field

[0001] The utility model relates to the technical field related to carbon sink systems, and more specifically, to a device for fixing and increasing carbon sink in forest soil. Background Art

[0002] Soil carbon fixation and sequestration research has been an important frontier in soil science research in the past decade. It is a measure to increase the carbon content of carbon pools other than the atmosphere. Sustainable management of soil carbon fixation and sequestration is a major need to address climate change and global soil degradation. Currently, soil carbon fixation and sequestration mainly utilizes plant photosynthesis to convert carbon dioxide into carbohydrates and fix them in the soil in the form of organic carbon.

[0003] Soil carbon fixation and carbon sink are affected by many factors, including soil type and texture, vegetation type and vegetation coverage, soil management measures and climatic factors; among them, the main factors for forest soil carbon fixation and carbon sink are vegetation type and vegetation coverage, which are achieved through photosynthesis of forest trees. However, forest vegetation is dense, and most of the sunlight shines from the top of the plants downward (toward the plants). After the plants grow, due to the obstruction of the leaves, the sunlight rarely reaches or cannot reach the middle and bottom layers of the plants. As a result, the leaves in the middle and bottom cannot carry out good photosynthesis and fail to perform photosynthesis conversion, thus affecting forest soil carbon fixation and carbon sink.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model;

[0025] Please refer to Figures 1 to 5 , in the present utility model, a device for forest soil carbon fixation and sink enhancement includes a bracket 100, a clamping mechanism 200, and a sunlight collection and refraction mechanism 300. The sunlight collection and refraction mechanism 300 includes a connecting frame 301. The inner side of the connecting frame 301 is fixedly connected with a light guide cover 302, and the light guide cover 302 plays a role in guiding light. The top of the light guide cover 302 is fixedly connected with a light collection cover 303 that closes the top of the light guide cover 302. The bottom of the connecting frame 301 is provided with a diffuser plate 304 located directly below the light collection cover 303;

[0026] Among them, there are two brackets 100 and two clamping mechanisms 200. The two brackets 100 are symmetrically arranged front and back and fixedly connected to one side of the connecting frame 301. The two clamping mechanisms 200 are symmetrically arranged up and down and fixedly arranged on the side of the bracket 100 away from the connecting frame 301.

[0027] In this embodiment, preferably, an L-shaped connecting rod 305 is fixedly connected to the side of the connecting frame 301 away from the bracket 100. The diffuser plate 304 is fixedly connected to the end of the L-shaped connecting rod 305 away from the connecting frame 301, and the diffuser plate 304 is inclined towards the direction of the clamping mechanism 200;

[0028] Specifically, because the diffuser plate 304 is inclined, when light hits the diffuser plate 304, it diffuses the light and evenly scatters the light towards the trees.

[0029] In this embodiment, preferably, the shape of the light collection cover 303 is an arc dome structure, and the light collection cover 303 is made of a light-concentrating spherical refraction lens material;

[0030] Specifically, the shape and material of the light collecting cover 303 are used to improve the light collecting effect.

[0031] In this embodiment, preferably, filter films 306 are respectively pasted on the surfaces of the light collecting cover 303 and the diffuser plate 304, and the wavelength band of the filter films 306 is 400nm - 720nm;

[0032] Specifically, light in the wavelength band of 400nm - 720nm, which promotes the growth of forest trees, can pass through the filter film 306, while preventing or reducing the passage of other spectra outside the range of 400nm - 720nm, significantly shortening the growth cycle of forest trees, enhancing photosynthesis. The trees absorb carbon dioxide in the atmosphere through photosynthesis and input the fixed carbon into the soil through their roots, thereby enhancing carbon fixation and carbon sink.

[0033] In this embodiment, preferably, the bracket 100 has a rectangular structure, and a support frame 101 arranged along the diagonal of the bracket 100 is fixedly connected to the inner side of the bracket 100;

[0034] Specifically, the strength of the bracket 100 is improved by the support frame 101.

[0035] In this embodiment, preferably, each clamping mechanism 200 includes a fixing plate 201 fixedly connected to the bracket 100. A bidirectional threaded rod 202 is rotatably arranged on the fixing plate 201 from front to back. Two oppositely arranged clamping plates 203 are arranged inside the fixing plate 201. Nuts 204 are fixedly embedded on the two clamping plates 203, and the bidirectional threaded rod 202 passes through the nuts 204 and is in threaded cooperation with them;

[0036] Specifically, by rotating the bidirectional threaded rod 202 and driving the nuts 204 through thread transmission, the clamping plates 203 are driven to move. The two clamping plates 203 moving towards each other move relatively and can clamp on the branches of forest trees to achieve installation.

[0037] In this embodiment, preferably, a groove 205 for accommodating the bidirectional threaded rod 202 and the clamping plates 203 is arranged on one side of the fixing plate 201 away from the bracket 100. The height of the groove 205 is the same as the thickness of the clamping plates 203, and the clamping plates 203 can move along the groove 205;

[0038] Specifically, since the height of the groove 205 is the same as the thickness of the clamping plates 203, when manually adjusting the bidirectional threaded rod 202 to drive the nuts 204 to move the clamping plates 203 through threads, the clamping plates 203 are limited by the fixing plate 201, avoiding the tendency of the clamping plates 203 to rotate circumferentially along with the bidirectional threaded rod 202 and realizing the linear movement of the clamping plates 203.

[0039] In this embodiment, preferably, through holes are formed at one ends of the clamping plates 203 away from the fixing plate 201, and bolts (not shown in the figure) can pass through between adjacent through holes for locking;

[0040] Specifically, it is further strengthened by means of bolt locking.

[0041] The working principle and usage process of the present utility model:

[0042] Contact the branches of forest trees with the fixing plate 201. Rotate the bidirectional threaded rod 202 to drive the clamping plate 203 to move and clamp the branches of the trees through the nut 204. Subsequently, the connection strength between the two clamping plates 203 can be further improved by bolts. The whole is fixed on the branches of forest trees through the upper and lower clamping mechanisms 200, and the lighting cover 303 is higher than the trees and located in the north;

[0043] When sunlight shines on the lighting cover 303, refraction occurs. The lighting cover 303 is equivalent to a huge refracting spherical lens. Therefore, the incident light can be refracted to make it vertically downward and shine on the diffuser plate 304. The diffuser plate 304 diffuses the light, enabling the light to pass through the dense branches and leaves and shine on the positions below the top of the trees, refracting the light to the middle and bottom leaves, so that the middle and bottom leaves can also carry out good photosynthesis, which is beneficial to the growth of the trees. It also absorbs carbon dioxide in the atmosphere by enhancing the photosynthesis of the trees, and inputs the fixed carbon into the soil through the roots, improving carbon fixation and carbon sink.

[0044] The electronic components and modules used in the content of this utility model can all be parts commonly used in the current market and can realize the specific functions in this case. Moreover, the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to the external power supply and control switch for use. Their specific circuit connection methods and usage methods are all publicly known technologies and will not be elaborated here.

[0045] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
