Description
Technical Field
[0001] This invention relates to the field of positioning device technology, and specifically to a positioning device for field sampling points of forest and grassland carbon sequestration. Background Technology
[0002] In grassland ecosystem carbon sink monitoring, the location and marking of field sampling points are crucial for ensuring the continuity and accuracy of carbon sink data. This is especially true in the hilly and gully areas of the Loess Plateau, where the terrain is undulating, the soil is loose, and sandstorms are frequent. In addition, there are human interference factors such as grazing, which place higher demands on the stability, adaptability, and convenience of sampling point positioning devices.
[0003] Existing forest and grassland carbon sequestration field sampling and positioning devices mostly adopt a simple structure of upright posts and ground insertion, which has obvious defects in actual use: On the one hand, the device's fixing structure is simple, relying only on simple insertion or counterweight for fixation. In complex terrains such as slopes and soft grasslands, the device is not stable enough and is easily tilted, displaced, or even overturned by wind, rain, or livestock, making it difficult to maintain the sampling marker stably for a long time. On the other hand, the overall size and weight of the device are too large, and most of them are non-foldable structures, making them inconvenient to carry on foot in the mountains. Furthermore, the deployment, adjustment, and retrieval steps are cumbersome, requiring step-by-step operations such as fixing, adjustment, and protection. This results in low efficiency for single-person operation and cannot meet the needs of efficient large-scale field sampling.
[0004] In addition, given the windy and sandy environment of the Loess Plateau, existing positioning devices generally lack adaptable wind and sand protection structures. Wind and sand can easily cover and erode the marking panels, resulting in unclear sampling information. Some devices with protective structures also require manual operation, further increasing the steps in field operations. At the same time, the devices have many parts and complex structures, resulting in high overall manufacturing and operating costs, which is inconsistent with the actual needs of limited field sampling funds and the emphasis on efficient and low-cost operation.
[0005] In summary, the present invention provides a device for locating field sampling points for forest and grassland carbon sequestration to solve the above-mentioned problems. Summary of the Invention
[0006] To address the aforementioned issues, this invention provides a positioning device for forest and grassland carbon sequestration field sampling points. This device is designed to adapt to the complex terrain and wind-blown sand environment of the Loess Plateau hilly and gully areas, improve the device's stability in soft soil and grazing disturbance scenarios, optimize its portability and ease of operation in the field, achieve synchronous linkage between fixing actions and wind and sand protection, reduce operational steps, lower field sampling operation costs, and improve the efficiency of forest and grassland carbon sequestration field sampling operations.
[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A field sampling point positioning device for forest and grassland carbon sequestration includes a device body, on which a marking component, a fixing component, and a portable support component are installed. The marking component is used to mark the sampling point location, the fixing component is used to fix the device body to the sampling point, and the portable support component is used to support the marking component. The device body is also equipped with a wind and sand protection linkage component, which is used to block the wind and sand from the Loess Plateau from covering the marking component. At the same time, the wind and sand protection linkage component works in conjunction with the fixing component and the portable support component to achieve linkage action, thereby reducing individual operation steps.
[0008] The fixing component is installed at the bottom of the main body of the device, the portable support component is installed vertically on the top of the fixing component and penetrates through the main body of the device, the marking component is installed on the top of the portable support component, and the sandstorm protection linkage component is nested on the outside of the portable support component and located below the marking component. When the fixing component completes the sampling point deployment and fixing action, the sandstorm protection linkage component unfolds simultaneously to form all-round sandstorm protection for the marking component. When the fixing component is released and prepared for recycling, the sandstorm protection linkage component retracts simultaneously to fit the portable support component.
[0009] Furthermore, the fixing component includes an anchoring base, several barbed anchor claws, and several connectors; the anchoring base is fixedly connected to the bottom of the main body of the device, the barbed anchor claws are evenly hinged to the side wall of the anchoring base, and the ends of the barbed anchor claws are provided with sharp serrated barbs. One end of the connector is hinged to each barbed anchor claw, and the other end of the connector is slidably engaged with the marking component.
[0010] Furthermore, the sandstorm protection linkage component includes a sandstorm protection cover, a lifting rod, and a return spring. The sandstorm protection cover is nested and installed on the outside of the portable support component. One end of the lifting rod is fixedly connected to the bottom of the sandstorm protection cover, and the other end of the lifting rod passes through the anchor base and is linked and snapped into place with the connector. The return spring is sleeved on the outside of the lifting rod, and both ends of the return spring abut against the top of the anchor base and the end of the lifting rod, respectively.
[0011] Furthermore, the portable support assembly includes a foldable support tube, a folding hinge, and a limiting buckle. The foldable support tube is vertically installed on the top of the anchoring base. The foldable support tube includes several hollow tube segments, which are hinged to each other by the folding hinge. The limiting buckle is set at the folding hinge. When folded, the limiting buckle is used to automatically engage and fix the hollow tube segments. When unfolded, the limiting buckle is used to lock the hollow tube segments. The top of the anchoring base has a storage slot that is compatible with the foldable support tube.
[0012] Furthermore, the signage component includes a sign, an angle-adaptive linkage seat, and an adjustment knob. The angle-adaptive linkage seat is fixedly installed on the top of the folding support tube. The sign is hinged to the side of the angle-adaptive linkage seat away from the folding support tube. The adjustment knob is located on the side of the angle-adaptive linkage seat and is used to simultaneously adjust the extension height of the folding support tube and the tilt angle of the sign.
[0013] Furthermore, the adjustment knob includes a knob body, which rotates in conjunction with the side wall of the angle adaptive linkage seat. The rotating shaft of the knob body passes through the angle adaptive linkage seat and is coaxially fixedly connected to a main gear. A first driven gear and a second driven gear are respectively meshed on both sides of the main gear. A bidirectional adjusting screw is coaxially fixedly connected to the first driven gear. The end of the bidirectional adjusting screw away from the first driven gear is threadedly connected to the hollow tube section. The first driven gear is used to drive the hollow tube section to extend and retract, thereby adjusting the overall height of the folding support tube. The second driven gear is coaxially fixedly connected to the hinge shaft of the signboard. The second driven gear is used to drive the signboard to rotate around the hinge shaft, thereby adjusting the tilt angle of the signboard.
[0014] Furthermore, several guide holes are provided on the side wall of the sandstorm protection cover, and the guide holes are evenly distributed around the circumference of the sandstorm protection cover.
[0015] Furthermore, the connector includes a pull rope, a sliding buckle, and a limiting block. One end of the pull rope is hinged to the hinge of the barbed anchor claw, and the other end of the pull rope passes through the anchoring base and is fixedly connected to the sliding buckle. The sliding buckle is slidably fitted with an indicator rod, and the limiting block is fixedly connected to the bottom of the indicator rod. The limiting block is used to limit the sliding stroke of the sliding buckle.
[0016] Furthermore, a torsion spring is provided at the hinge of the barbed anchor claw. One end of the torsion spring is fixedly connected to the anchor base, and the other end of the torsion spring is fixedly connected to the barbed anchor claw. The torsion spring is used to realize the automatic retraction and reset of the barbed anchor claw.
[0017] Furthermore, a flexible dustproof buffer layer is provided on the inside of the sandstorm protection cover to prevent fine sand from entering the inside of the sandstorm protection cover.
[0018] The above approach has the following beneficial effects:
[0019] 1. This solution achieves synchronized action of device fixation and wind and sand protection through a purely mechanical linkage design of the fixing component and the wind and sand protection linkage component. Compared with the traditional technology where the positioning device fixing component and the protection component are independent and require separate operation, it greatly reduces the operation steps of field sampling. It can complete the dual action without additional power, which not only reduces the operation difficulty of sampling personnel, but also significantly improves the efficiency of field sampling. It is suitable for the needs of single-person sampling and convenient operation in the hilly and gully areas of the Loess Plateau. At the same time, it avoids the cumbersome process of operating the protection component separately and reduces operation errors.
[0020] 2. The fixing components of this solution adopt a combination structure of barbed anchor claws and torsion springs. The sharp serrated barbs at the ends of the barbed anchor claws can form multi-point engagement with the soft soil of the Loess Plateau, and when unfolded, they form a ring-shaped protective barrier. Compared with the simple fixing structure and poor adaptability of the positioning device in traditional technology, this solution effectively improves the fixing stability of the device in complex terrain. It can resist the risk of displacement caused by rainwater erosion and wind, and can also prevent interference from grazing livestock, ensuring the long-term stability of the sampling point markers. At the same time, the torsion spring can realize the automatic retraction and reset of the barbed anchor claws, further improving the convenience of device retrieval.
[0021] 3. The wind and sand protection linkage component of this solution adopts a wind and sand protection cover with a guide hole and a flexible dustproof buffer layer. With the linkage action of the lifting rod and the return spring, compared with the positioning device in the traditional technology that lacks a targeted wind and sand protection structure or has poor protection effect, it can accurately block the wind and sand of the Loess Plateau from covering and eroding the marking component. The guide hole can guide the wind and sand to be discharged quickly and reduce accumulation, and the flexible dustproof buffer layer can block the entry of fine wind and sand, ensuring that the sampling information on the sign is clearly identifiable. At the same time, the protective cover can shrink and fit the portable support component in a synchronous manner without affecting the folding and storage of the device, thus balancing the wind and sand protection effect and portability.
[0022] 4. The portable support component of this solution adopts a foldable hollow tube structure, combined with the storage slot of the anchor base. The adjustment knob achieves synchronous adjustment of the support height and the angle of the marker through gear linkage. Compared with the traditional positioning device, which is bulky, inconvenient to carry, and cumbersome to adjust, this solution significantly reduces the overall weight of the device and shrinks the storage volume. It is convenient for sampling personnel to carry on foot in the rugged mountain sampling area. At the same time, the synchronous adjustment function does not require step-by-step operation and can quickly adjust the marker to a horizontal and visible state, which is suitable for the diverse sloping terrain of the Loess Plateau. In addition, the hollow tube design reduces the use of consumables and lowers the manufacturing cost of the device, which meets the actual needs of high field sampling expenses.

[0030] The following detailed description illustrates the specific implementation method:
[0031] Example 1:
[0032] As attached Figures 1 to 3As shown: A field sampling point positioning device for forest and grassland carbon sequestration includes a main body 1. The main body 1 is equipped with a marking component, a fixing component, and a portable support component. The marking component marks the sampling point location, the fixing component secures the main body 1 to the sampling point, and the portable support component supports the marking component. A wind and sand protection linkage component is also installed on the main body 1. This linkage component prevents wind and sand from covering the marking component. Simultaneously, the wind and sand protection linkage component works in conjunction with the fixing component and the portable support component to achieve a coordinated action, reducing individual operation steps. The fixing component is installed at the bottom of the main body 1, the portable support component is vertically installed on top of the fixing component and penetrates the main body 1, the marking component is installed at the top of the portable support component, and the wind and sand protection linkage component is nested outside the portable support component and located below the marking component. When the fixing component completes the sampling point placement and fixing action, the wind and sand protection linkage component deploys simultaneously, providing all-around wind and sand protection for the marking component. When the fixing component is released for retrieval, the wind and sand protection linkage component retracts simultaneously, fitting snugly against the portable support component.
[0033] The fixing assembly includes an anchoring base 2, several barbed anchor claws 3, and several connectors. The anchoring base 2 is fixedly connected to the bottom of the main body 1 of the device. The barbed anchor claws 3 are evenly hinged to the side walls of the anchoring base 2. Each barbed anchor claw 3 has sharp, serrated barbs at its end. One end of each connector is hinged to each barbed anchor claw 3, and the other end of the connector is slidably engaged with the marking assembly. A torsion spring is provided at the hinge of each barbed anchor claw 3. One end of the torsion spring is fixedly connected to the anchoring base 2, and the other end of the torsion spring is fixedly connected to the barbed anchor claw 3. The torsion spring is used to realize the automatic retraction and reset of the barbed anchor claw 3.
[0034] The sandstorm protection linkage component includes a sandstorm protection cover 4, a lifting rod, and a return spring. The sandstorm protection cover 4 is a conical structure with an open top and a transparent bottom. It is nested and installed on the outside of the portable support component. One end of the lifting rod is fixedly connected to the bottom of the sandstorm protection cover 4, and the other end passes through the anchor base 2 and is linked and snapped into place by a connector. The return spring is sleeved on the outside of the lifting rod, with its two ends abutting against the top of the anchor base 2 and the end of the lifting rod, respectively. Several guide holes are evenly distributed around the circumference of the sandstorm protection cover 4 on its side wall. A flexible dustproof buffer layer is provided inside the sandstorm protection cover 4 to prevent fine sand from entering the interior of the cover.
[0035] The portable support assembly includes a foldable support tube 5, a folding hinge, and a limiting buckle. The foldable support tube 5 is vertically installed on the top of the anchoring base 2. The foldable support tube 5 includes several hollow tube segments, which are hinged to each other by the folding hinge. The limiting buckle is set at the folding hinge. After folding, the limiting buckle is used to automatically engage and fix the hollow tube segments. After unfolding, the limiting buckle is used to lock the hollow tube segments. The top of the anchoring base 2 has a storage slot that is compatible with the foldable support tube 5.
[0036] The signage assembly includes a signboard 6, an angle-adaptive linkage seat 7, and an adjustment knob 8. The angle-adaptive linkage seat 7 is fixedly installed on the top of the folding support tube 5. The signboard 6 is hinged to the side of the angle-adaptive linkage seat 7 away from the folding support tube 5. The adjustment knob 8 is located on the side of the angle-adaptive linkage seat 7. The adjustment knob 8 is used to simultaneously adjust the extension height of the folding support tube 5 and the tilt angle of the signboard 6.
[0037] The adjustment knob 8 includes a knob body, which is rotatably engaged with the side wall of the angle adaptive linkage seat 7. The rotating shaft of the knob body passes through the angle adaptive linkage seat 7 and is coaxially fixedly connected to a main gear. A first driven gear and a second driven gear are respectively meshed on both sides of the main gear. A bidirectional adjusting screw is coaxially fixedly connected to the first driven gear. The end of the bidirectional adjusting screw away from the first driven gear is threadedly connected to the hollow tube section. The first driven gear is used to drive the hollow tube section to extend and retract, thereby adjusting the overall height of the folding support tube 5. The second driven gear is coaxially fixedly connected to the hinge shaft of the signboard 6. The second driven gear is used to drive the signboard 6 to rotate around the hinge shaft, thereby adjusting the tilt angle of the signboard 6.
[0038] The connector includes a pull rope 9, a sliding buckle 10, and a limiting block. One end of the pull rope 9 is hinged to the hinge of the barbed anchor claw 3, and the other end of the pull rope 9 passes through the anchoring base 2 and is fixedly connected to the sliding buckle 10. The sliding buckle 10 is slidably fitted with an indicator rod 601, and the limiting block is fixedly connected to the bottom of the indicator rod 601. The limiting block is used to limit the sliding stroke of the sliding buckle 10. When the marker rod 601 is pressed down, the sliding buckle 10 moves downward along the marker rod 601, and the linkage rope 9 pulls all the barbed anchor claws 3 outward to complete the device fixation. At the same time, the sliding buckle 10 presses the top of the lifting rod, pushing the lifting rod upward and causing the sandstorm protection cover 4 to rise and unfold. When the marker rod 601 is pulled upward, the sliding buckle 10 moves upward along the marker rod 601, the linkage rope 9 loosens, and the barbed anchor claws 3 retract under the action of their own elastic reset parts, releasing the fixation. At the same time, the lifting rod moves downward under the elastic force of the reset spring, causing the sandstorm protection cover 4 to retract. This purely mechanical linkage structure can simultaneously solve the three major requirements of fixation stability, sandstorm protection, and ease of operation. The linkage logic is not obvious and is the core support for realizing the overall creativity. It does not require additional power and is suitable for outdoor scenarios without power.
[0039] The specific implementation process is as follows: At the grassland ecosystem carbon sink sampling site in the hilly and gully area of the Loess Plateau, the field sampling personnel first prepare to unfold the main body 1 of the device. Without the aid of any additional tools, a single person can complete all operations, greatly improving the efficiency of sampling preparation and reducing labor costs. The sampling personnel first take out the folded main body 1 of the device. At this time, the foldable support tube 5 of the portable support component is in a folded storage state. The hollow tube section is hinged by the folding hinge and automatically locked by the limiting buckle. The folded support tube is completely stored in the storage groove at the top of the anchoring base 2. The wind and sand protection cover 4 of the wind and sand protection linkage component is in a retracted state, closely fitting the outside of the folded support tube. The barbed anchor claw 3 is in a retracted state under the elastic force of the torsion spring, fitting the side wall of the anchoring base 2. The entire device is small in size and lightweight, making it easy for the sampling personnel to carry on foot in the rugged mountain sampling area. It solves the pain points of traditional devices being large in size and inconvenient to carry, and is suitable for the field sampling environment in the hilly and gully area of the Loess Plateau.
[0040] Upon reaching the preset sampling point, the sampling personnel first release the locking buckle from the folding support tube 5. The hollow section of the folding support tube 5 is then gradually unfolded using the folding hinge. After unfolding to a suitable height, the locking buckle automatically locks the hollow section, ensuring the support tube remains vertically stable and providing solid support for the marking component and the wind and sand protection linkage component. At this point, the sampling personnel place the anchoring base 2 at the preset sampling point position, grasp the marking rod 601 of the marking component, and slowly press down on the marking rod 601. The marking rod 601 causes the sliding buckle 10, which is slidably mounted on the outside, to move downwards synchronously. During the movement, the sliding buckle 10 is restricted by the limiting block to prevent excessive sliding and damage to the linkage structure, ensuring the stability of the linkage action.
[0041] When the sliding buckle 10 moves downward, it simultaneously pulls the pull rope 9 fixed to it. The pull rope 9 passes through the inside of the anchoring base 2, causing several barbed anchor claws 3 hinged to it to unfold outward simultaneously. During the unfolding process, the barbed anchor claws 3 overcome the elasticity of the torsion spring and gradually separate from the state of contact with the side wall of the anchoring base 2, and are evenly distributed in a ring. The sharp serrated barbs at their ends quickly insert into the soft soil of the Loess Plateau, forming a multi-point interlocking fixation, which greatly improves the fixation stability of the device and can effectively resist the risk of displacement caused by rainwater erosion and wind. At the same time, the unfolded barbed anchor claws 3 form a ring-shaped protective barrier, which can block the contact of grazing livestock and prevent the device from tilting or shifting due to livestock collisions. It is perfectly adapted to the dual scenarios of soft soil and grazing disturbance in the hilly and gully areas of the Loess Plateau, and solves the core pain points of traditional devices being unstable and easily affected by external interference.
[0042] Simultaneously, when the sliding buckle 10 moves downward to a certain distance, its bottom presses against the top of the lifting rod of the sandstorm protection linkage component, pushing the lifting rod upward along the through hole of the anchor base 2. During the upward movement of the lifting rod, it presses against the outer sleeved return spring, causing the return spring to be in a compressed state. The lifting rod simultaneously drives the sandstorm protection cover 4 fixedly connected to the top to move upward. The sandstorm protection cover 4 slides upward along the foldable support tube 5 of the portable support component, gradually unfolding and covering the signboard 6 of the sign component, forming all-round sandstorm protection. At this time, the conical structure of the sandstorm protection cover 4 can effectively block the sandstorms of the Loess Plateau from directly covering the signboard 6. Its top opening and bottom transparency design does not affect the visibility of the signboard 6, and can accurately block the sandstorm invasion, solving the pain point of blurred sign information caused by strong sandstorms on the Loess Plateau.
[0043] The guide holes evenly distributed circumferentially on the side walls of the sandstorm protection cover 4 are designed with an inclination consistent with the prevailing sandstorm flow direction on the Loess Plateau. This guides the sandstorm to be discharged quickly along the guide holes, reducing the accumulation of sandstorm inside the cover and preventing the device from shifting its center of gravity or tilting due to sandstorm accumulation. It also reduces the impact of sandstorm on the side walls of the cover, extending the service life of the cover. The flexible dustproof buffer layer set inside the cover can effectively block fine sandstorms from entering the cover, preventing fine sandstorms from damaging the sampling information on the surface of the identification plate 6. This further enhances the sandstorm protection effect, ensuring that the sampling point information on the identification plate 6 is clearly identifiable and providing a guarantee for the accuracy of carbon sequestration sampling data.
[0044] After the device is fixed in place, the sampling personnel can adjust the telescopic height of the folding support tube 5 and the tilt angle of the sign 6 simultaneously by adjusting the knob 8, according to the slope terrain of the sampling point. This eliminates the need for step-by-step operations and greatly improves the ease of operation. In specific operation, the sampling personnel turn the knob body of the adjustment knob 8. The knob body drives the main gear of its rotating shaft through the angle adaptive linkage seat 7 to rotate synchronously. The first driven gear and the second driven gear meshing on both sides of the main gear rotate synchronously at the same time. The first driven gear drives the coaxially fixed bidirectional adjusting screw to rotate. The bidirectional adjusting screw is threadedly connected to the hollow tube section at the top of the folded support tube 5. Through threaded transmission, the hollow tube section is driven to extend and retract, thereby adjusting the overall height of the folded support tube 5 so that the sign 6 is at a height that is easy to observe. The second driven gear is coaxially fixedly connected to the hinge shaft of the sign 6, driving the sign 6 to rotate around the hinge shaft and adjusting the tilt angle of the sign 6. With the adaptive action of the angle adaptive linkage seat 7, it ensures that the sign 6 always remains horizontal, avoiding the blurring of the sign information due to the terrain slope. It realizes the synchronous adjustment of the support height and the sign angle, breaking the limitation of traditional devices that require step-by-step adjustment. It is convenient and efficient to operate and adaptable to the diverse sloping terrain of the Loess Plateau hilly and gully areas.
[0045] After sampling is completed, the sampling personnel perform the device retrieval operation, which can be completed quickly by a single person without the need for additional tools. The sampling personnel pull the marker rod 601 upwards, which causes the sliding buckle 10 to move upwards along the marker rod 601. The pull rope 9 then loosens, and the barbed anchor claw 3 automatically retracts and resets under the elastic force of the torsion spring, detaching from the soil and adhering to the side wall of the anchor base 2, thus releasing the device from its fixed state. At the same time, the lifting rod moves downwards under the elastic force of the reset spring, causing the sandstorm protection cover 4 to retract synchronously, gradually adhering to the outside of the foldable support tube 5 of the portable support component, completing the retraction and storage of the sandstorm protection component.
[0046] Subsequently, the sampling personnel released the locking buckle on the foldable support tube 5 and gradually folded the hollow tube section through the folding hinge. After folding, the locking buckle automatically engaged and fixed the hollow tube section, so that the folded support tube was completely stored in the storage groove of the anchor base 2. At this time, the entire device returned to the folded state. It is small in size and easy to carry, and can be easily carried by the sampling personnel to the next sampling point.
[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
