Description

Technical Field

[0001] This application relates to the field of land survey technology, specifically to a data collection bracket for land change surveys. Background Technology

[0002] The land use change survey is an updated survey of changes in the current state of land use. Based on the results of the Third National Land Survey and the previous year's change survey, it updates relevant information on land parcels through on-site investigations and evidence collection at the county level, and grasps the spatial distribution, quantity, quality, and changes in land use status of natural resources. The field data collection stand for the land use change survey is mainly used to support the collection equipment (such as tablets, cameras, etc.) to ensure the stability of data collection. Its structure generally features a portable design: adopting a foldable / telescopic structure, such as hinged support plates with pins or telescopic brackets, to reduce storage volume and facilitate carrying to complex terrain.

[0003] During data collection, the support frame needs to be placed stably on the ground. However, some terrains are uneven, which can cause some of the support rods to be suspended in the air when the frame is rotated and extended. This can cause the data collection equipment placed on the frame to tip over due to instability, affecting the data collection process. Utility Model Content

[0004] The purpose of this application is to provide a support system for field data collection in land change surveys to address the problems mentioned in the background section.

[0005] To achieve the above objectives, this application provides the following technical solution: a data acquisition bracket for land change surveys, comprising: a data acquisition bracket body, a rotating fixing component, an auxiliary plugging component, and a connecting component. The data acquisition bracket body includes a fixed base and a support rod rotatably mounted at the bottom of the fixed base. There are four sets of support rods. The rotating fixing component is mounted on the outer wall of the bottom end of the support rod. The rotating fixing component includes a fixing block welded to the outer wall of the bottom of each set of support rods. A circular hole is formed inside the fixing block, and a connecting shaft is rotatably mounted inside the circular hole. Two sets of spaced protrusions are provided on the outer wall of the connecting shaft, with the protrusions on both sides of the outer wall of the fixing block. The rotating fixing component also includes a mounting block welded to one end of the outer wall of the connecting shaft, with a sliding hole formed on the mounting block. The auxiliary plugging component is mounted on one side of the outer wall of the support rod and includes a connecting rod and a plugging rod. The diameters of the connecting rod and the plugging rod are adapted to the inner diameter of the sliding hole. The connecting component is mounted on the connecting rod and the plugging rod to allow for detachable connection between them.

[0006] By adopting the above technical solution, it is possible to provide auxiliary support for the suspended support rod and provide effective stability.

[0007] A further feature of this invention is that a threaded hole is provided on one side of the outer wall of the mounting block, a threaded rod is rotatably provided inside the threaded hole, a handle is provided at one end of the threaded rod, and the threaded hole is connected to the sliding hole.

[0008] By adopting the above technical solution, the handle can be rotated by a person holding it.

[0009] A further feature of this invention is that the auxiliary plug-in assembly includes a fixing block welded to one side of the outer wall of each set of support rods, and the number of fixing blocks on each set of support rods is four. The fixing block has an arc-shaped groove, and the fixing block is made of elastic metal. The connecting rod and the plug-in rod are both engaged in the arc-shaped groove of the fixing block.

[0010] By adopting the above technical solution, the fixing block can provide a space for the connecting rod and the plug rod to be placed inside for fixation.

[0011] A further feature of this invention is that the connecting assembly includes a connector welded to the top of the plug rod and the top of the connecting rod, the connector having an I-shaped cross-section and the top of the connector having an inclined surface.

[0012] By adopting the above technical solution, the shape of the top of the connector can provide the conditions for insertion.

[0013] A further feature of this invention is that the connecting assembly includes rectangular holes on both sides of the outer wall of the bottom end of each set of connecting rods, and there are two sets of rectangular holes. A mounting plate is welded to the inner wall of the rectangular holes, and a through hole is provided inside the mounting plate.

[0014] By adopting the above technical solutions, rectangular holes and through holes can provide internal structural displacement.

[0015] A further feature of this invention is that the connecting assembly also includes a guide rod slidably disposed within the through hole of the mounting plate. The end of the guide rod away from the rectangular hole is integrally formed with a hand-held protrusion. A limit block is welded to the end of the guide rod located inside the rectangular hole, and the limit block is disposed inside the rectangular hole.

[0016] By adopting the above technical solution, the guide rod can achieve stable displacement inside the through hole.

[0017] A further feature of this invention is that the connecting assembly also includes a spring sleeved on the guide rod, with both ends of the spring welded to the outer walls of the mounting plate and the limiting block, respectively.

[0018] By adopting the above technical solution, the spring can drive the connected structure to produce displacement according to its own elastic force.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] (1) By setting an auxiliary plug-in component and a rotating fixing component, the rotating fixing component can change the angle of the plug-in rod placed inside. When one of the support rods is in a suspended state, the plug-in rod is connected to multiple connecting rods, and the plug-in rod can be vertically slid into the soil. At this time, the suspended support rod is supported by the plug-in rod, and the collection device placed above the fixing seat can maintain the stability during operation. When facing the normal soil surface, the connecting rod and plug-in rod used for support can be stored on the outer wall of the support rod by the fixing block, providing effective storage.

[0021] (2) By setting up connecting rods, plug-in rods and connecting components, the connecting components can quickly install the connecting rods and plug-in rods, thereby extending the plug-in rods through multiple sets of connecting rods. When the plug-in rods do not need to be supported and are stored, the connecting rods and plug-in rods connected by the connecting components can be quickly unlocked by flicking, thereby achieving disassembly and storage.

[0034] The rotating fixing assembly 3 includes a fixing block 301 welded to the bottom outer wall of each set of support rods 2. The fixing block 301 has a circular hole inside. A connecting shaft 302 is rotatably installed inside the circular hole of the fixing block 301. Two sets of spaced protrusions are provided on the outer wall of the connecting shaft 302. The protrusions of the connecting shaft 302 are located on both sides of the outer wall of the fixing block 301. A mounting block 303 is welded to one end of the outer wall of the connecting shaft 302. A threaded hole 304 is provided on one side of the outer wall of the mounting block 303. A threaded rod 305 is rotatably installed inside the threaded hole 304. A handle 306 is provided at one end of the threaded rod 305. A sliding hole 307 is opened on the mounting block 303 and is connected to the threaded hole 304.

[0035] The auxiliary plug-in assembly 4 includes a fixing block 401 welded to one side of the outer wall of each set of support rods 2. There are four sets of fixing blocks 401 on each set of support rods 2. The fixing blocks 401 are provided with arc-shaped grooves and are made of elastic metal. The connecting rod 402 and the plug-in rod 403 are engaged in the arc-shaped grooves of the fixing blocks 401. The diameters of the connecting rod 402 and the plug-in rod 403 are adapted to the inner diameter of the sliding hole 307.

[0036] The connecting component 5 includes a connector 501 welded to the top of the plug rod 403 and the top of the connecting rod 402. The connector 501 has an I-shaped cross-section and the top of the connector 501 is an inclined surface. Rectangular holes 502 are opened on both sides of the bottom outer wall of each set of connecting rods 402. There are two sets of rectangular holes 502. A mounting plate 503 is welded to the inner wall of the rectangular holes 502. A through hole is opened inside the mounting plate 503. A guide rod 504 is slidably installed in the through hole of the mounting plate 503. A hand-held protrusion is integrally formed at the end of the guide rod 504 away from the rectangular hole 502. A limit block 505 is welded to the end of the guide rod 504 located inside the rectangular hole 502. The limit block 505 is located inside the rectangular hole 502. A spring 506 is sleeved on the guide rod 504. The two ends of the spring 506 are respectively welded to the outer walls of the mounting plate 503 and the limit block 505.

[0037] Working principle: The data collection device is fixed on the fixed base 1. At this time, the four sets of support rods 2 at the bottom of the fixed base 1 support the fixed base 1 and the data collection device above. When some of the support rods 2 are suspended in the air on the rugged soil surface, the auxiliary plug-in component 4 is connected through the connecting component 5. At this time, the angle of the auxiliary plug-in component 4 is adjusted to a vertical state inside the rotating fixed component 3. Then, stable support is achieved by sliding it into the soil.

[0038] Based on the suspended height, multiple sets of connecting rods 402 and plug-in rods 403 are selected for connection. Specifically, the connecting rods 402 and plug-in rods 403 are removed from the fixing block 401, and the connector 501 of the plug-in rod 403 is inserted into the two sets of limiting blocks 505 at the bottom of the connecting rod 402. At this time, the limiting blocks 505 are displaced by the connector 501, thus sliding to both sides. When the connector 501 is inserted into the designated position of the connecting rod 402, the spring 506 will press and push the limiting blocks 505. At this time, the limiting blocks 505 can slide stably inside the rectangular hole 502. When the spring 506 pushes, the limiting blocks 505 can connect with the guide rod 504 in the mounting plate 503, thereby achieving stable displacement, so that the two sets of limiting blocks 505 limit the connector 501, thereby connecting the connecting rod 402 and the plug-in rod 403.

[0039] The connected rod 402 and the plug rod 403 are slid into the sliding hole 307. At this time, the connecting shaft 302 on the outer wall of the mounting block 303 can change the angle inside the fixing block 301, so that the connected rod 402 and the plug rod 403 in the sliding hole 307 of the mounting block 303 are in a vertical state. By sliding the connected rod 402 and the plug rod 403, the connected rod 402 and the plug rod 403 are inserted into the soil. When the connected rod 402 and the plug rod 403 move to the designated position inside the soil and play a supporting role, the threaded rod 305 is rotated inside the threaded hole 304 by holding the handle 306. During the rotation of the threaded rod 305, displacement occurs, so that one end of the threaded rod 305 is pressed against the outer wall of the connected rod 402 or the plug rod 403, so that the fixing block 301 is fixed on the outer wall of the connected rod 402 or the plug rod 403.
