Description

Technical Field

[0001] This utility model is a mining ecological environment survey device, belonging to the field of ecological environment survey. Background Technology

[0002] In mine ecological environment surveys, quadrats are a core tool for assessing vegetation restoration, soil quality, and biodiversity. Their core value lies in providing standardized measurement benchmarks for key indicators such as species abundance statistics, population density calculations, and vegetation cover assessments by defining fixed-area survey units. Whether monitoring the natural vegetation restoration process in abandoned mine sites or evaluating the ecological effectiveness of artificially restored areas, quadrats ensure the relevance and comparability of survey data through clearly defined boundaries—for example, using fixed units of 1m×1m or 2m×2m allows for precise comparison of vegetation growth differences in different mining areas and at different restoration stages, providing data support for optimizing ecological restoration plans.

[0003] The terrain in mining areas is extremely complex, especially in open-pit mines or mine slopes, which are generally characterized by varying slopes and rugged surfaces. This places stringent requirements on the accuracy of quadrat placement. If the quadrat is not placed horizontally but tilts with the slope, it will directly lead to deviations in the surveyed area: in areas with steep slopes, the horizontal projected area of ​​the space actually enclosed by the tilted quadrat will be significantly smaller than the theoretical area of ​​the quadrat. In this case, if the "number of species per unit area" is still calculated based on the standard area, the statistical results will be inflated, leading to a misjudgment of the vegetation density in that area. Conversely, if the quadrat tilts upwards on the slope, its boundaries may exceed the preset survey range, including vegetation and soil samples from adjacent areas in the statistics, breaking the independence of the survey unit, resulting in data distortion, and failing to accurately reflect the ecological status of the target area. Only when the quadrat is strictly placed horizontally can its four sides accurately correspond to the distances on the horizontal plane, ensuring that the actual surveyed area is completely consistent with the theoretical area. This provides reliable basic data for subsequent calculations of density, cover, and other indicators, avoiding assessment errors caused by area deviations.

[0004] To adapt to the complex terrain with varying slope inclinations in mines and ensure the levelness of the quadrats, the conventional practice is to install outriggers at the four corners of the quadrats. By adjusting the length of these outriggers, the tilting effect caused by differences in slope elevation can be offset. However, mine survey areas are often vast, requiring the placement of quadrats at multiple locations. To meet the adjustment needs of different slope gradients, the outriggers must be designed to be long enough to handle significant terrain undulations. These longer outriggers not only occupy more space during transportation, increasing the burden on backpacks or toolboxes, but may also cause bumps and knocks during walking, affecting the efficiency of surveyors. Furthermore, in areas with narrow slopes or dense vegetation, the limited operating space further prolongs the placement time of the quadrats, reducing overall survey efficiency and becoming a practical challenge that urgently needs optimization in mine ecological environment surveys. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mining ecological environment survey device to solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a mining ecological environment survey device, comprising: Four quadrats are provided, and the four quadrats together form a rectangular frame structure. The ends of two adjacent quadrats are connected by a right-angle bend. There are four sleeves, which are respectively connected and fixed to four right-angle bends. A column is inserted inside the sleeve. The outer surface of the sleeve is threaded with a positioning screw to limit the relative position of the column and the sleeve. A threaded head is installed at the lower end of the column, and an internal threaded sleeve is connected and fixed at the upper end of the column. The threaded head on one column is threaded into the internal threaded sleeve on another column.

[0007] Furthermore, a compression spring is installed inside the internal threaded sleeve on the side near the column rod, and a plug is connected to the end of the compression spring away from the column rod. Under the action of the spring's rebound force, the plug is flush with the end of the internal threaded sleeve away from the column rod.

[0008] Furthermore, two guide grooves are provided on the side of the internal threaded sleeve near the column rod, and the end of the guide groove away from the column rod is closed. Two guide blocks are installed on the outer surface of the plug, and the two guide blocks are respectively inserted into the two guide grooves.

[0009] Furthermore, each end of the quadrat is equipped with a connector, and the end of the connector furthest from the quadrat is inserted into a right-angle bend.

[0010] Furthermore, the connector is a hollow structure, and the quadrature strip is a hollow structure.

[0011] Furthermore, a straight threaded cylinder is threaded onto the threaded head of the lowest column rod, and a pointed end is installed on the lower end of the straight threaded cylinder.

[0012] Furthermore, the straight threaded cylinder is fitted with a blocking disc that is connected and fixed to the straight threaded cylinder to limit the depth of the tip inserted into the ground. The blocking disc has a regular hexagonal structure.

[0013] Furthermore, a nut communicating with the internal space of the sleeve is installed on the outer surface of the sleeve, and the positioning screw is threadedly connected to the nut.

[0014] Furthermore, two connecting plates are installed on the outer surface of the sleeve, and the connecting plates are connected and fixed to the right-angle bend.

[0015] The beneficial effects of this utility model are: The use of a threaded head and internal threaded sleeve allows for the detachable splicing of multiple support rods. Each support rod is short and can be disassembled into independent components during transport, significantly reducing space requirements and avoiding the bumping and knocking issues associated with carrying traditional long support legs. This also reduces the burden on surveyors' backpacks or toolboxes, making it particularly suitable for long-distance walking and multi-point surveys in mining areas. When facing mine slopes with varying gradients, the number of support rods can be flexibly increased or decreased according to the terrain, eliminating the need to carry fixed-length support legs and balancing adjustability with portability.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a mining ecological environment survey device, including quadrature strips 1, four quadrature strips 1 are provided, the quadrature strips 1 are hollow structures, the ends of two adjacent quadrature strips 1 are connected by a right-angle bend 11, that is, hollow connectors 12 are installed at both ends of the quadrature strips 1, so that the end of the connector 12 away from the quadrature strip 1 is inserted into the right-angle bend 11, so that the four quadrature strips 1 together form a rectangular frame structure of the quadrature frame.

[0019] See Figures 1-5 There are four pipe sleeves 2, which are respectively connected and fixed to four right-angle bends 11. Two connecting plates 23 are installed on the outer surface of the pipe sleeve 2, so that the connecting plates 23 are connected and fixed to the right-angle bends 11, thereby increasing the connection range between the pipe sleeve 2 and the right-angle bends 11 and improving the stability of the pipe sleeve 2 installation.

[0020] A column rod 3 is inserted inside the sleeve 2. A positioning screw 21 is threaded on the outer surface of the sleeve 2 to limit the relative position of the column rod 3 and the sleeve 2. A nut 22 that communicates with the internal space of the sleeve 2 is installed on the outer surface of the sleeve 2, so that the positioning screw 21 and the nut 22 are threadedly connected to achieve a stable connection between the positioning screw 21 and the sleeve 2.

[0021] A threaded head 32 is installed at the lower end of the column rod 3, and an internal threaded sleeve 31 is connected and fixed at the upper end of the column rod 3. The threaded head 32 on one column rod 3 is threaded into the internal threaded sleeve 31 on another column rod 3. The cooperation between the threaded head 32 and the internal threaded sleeve 31 enables the detachable splicing of multiple column rods 3. The short length of a single column rod 3 allows it to be disassembled into an independent component during transportation, greatly reducing the space occupied and avoiding the bumping problems that occur when carrying traditional long outriggers. This also reduces the burden on the backpacks or toolboxes of investigators, making it particularly suitable for long-distance walking and multi-point surveys in mining areas. When facing mining slopes with different gradients, the number of column rods 3 can be flexibly increased or decreased according to the terrain undulations, eliminating the need to carry long outriggers of fixed length, thus balancing adjustment needs and portability. The four sleeves 2 correspond to the four corners of the sample frame. The column rod 3 in each sleeve 2 can slide up and down independently. The extension length of the column rod 3 can be adjusted by loosening the positioning screw 21, and then the positioning screw 21 can be tightened to fix the position. To address the varying slope inclinations of mine slopes, the heights of the four corner posts 3 can be adjusted—for example, shortening the posts 3 at higher slopes and lengthening the posts 3 at lower slopes—to ensure that the rectangular frame formed by the quadrat strips 1 remains horizontal. This avoids deviations in the survey area caused by inclination, ensuring that the actual survey area matches the theoretical area and providing a reliable basis for calculating indicators such as species quantity and population density.

[0022] See Figure 4 and Figure 5 A compression spring 52 is installed inside the internal threaded sleeve 31 near the column rod 3. A plug 5 is connected to the end of the compression spring 52 away from the column rod 3. Under the rebound force of the compression spring 52, the plug 5 is flush with the end of the internal threaded sleeve 31 away from the column rod 3. Two guide grooves 33 are formed inside the internal threaded sleeve 31 near the column rod 3. The end of the guide groove 33 away from the column rod 3 is closed. Two guide blocks 51 are installed on the outer surface of the plug 5, allowing the two guide blocks 51 to be inserted into the two guide grooves 33 respectively, thus restricting the movement trajectory of the plug 5 and preventing the plug 5 and compression spring 52 from falling out of the internal threaded sleeve 31. When not spliced, the plug 5 is flush with the end of the internal threaded sleeve 31 under the action of the compression spring 52, effectively preventing dust, rainwater, gravel, and other impurities commonly encountered in mine surveys from entering the interior of the internal threaded sleeve 31. This ensures the long-term reliability of the column rod 3's adjustment and splicing functions, adapting to the harsh environment of high dust and humidity in mines.

[0023] See Figure 1 , Figure 2 , Figure 4 and Figure 5The threaded head 32 of the lowest column 3 is threadedly connected to a straight threaded cylinder 4, and a pointed tip 42 is installed at the lower end of the straight threaded cylinder 4. A blocking disc 41, which is fixed to the straight threaded cylinder 4, is used to limit the insertion depth of the pointed tip 42 into the ground. The blocking disc 41 has a regular hexagonal structure. The threaded head 32 of the lowest column 3 is connected to the straight threaded cylinder 4, and the pointed tip 42 at the lower end can be inserted into the surface soil or gravel layer of the mine to enhance the anti-tipping ability of the column 3. The blocking disc 41 with a regular hexagonal structure can limit the insertion depth of the pointed tip 42, avoid the difficulty in adjusting the height of the column 3 due to excessive insertion, and prevent the device from sinking under vibration or slight external force, ensuring the long-term stability of the horizontal state of the sample frame, which is especially suitable for loose surface environment in mines.
