Description

Technical Field

[0001] This invention relates to the field of wild mammal surveys, and more specifically to a fixed device and deployment method for monitoring wild mammals. Background Technology

[0002] The "Technical Guidelines for Environmental Impact Assessment: Format and Content of Environmental Impact Reports for Nuclear Power Plants" requires that the biological populations within the survey area be described. The "Technical Guidelines for Environmental Impact Assessment: Ecological Impacts" requires that the survey content of the terrestrial ecological status include the fauna, species composition, and distribution characteristics. The "Technical Guidelines for Biodiversity Observation: Terrestrial Mammals" specifies in detail the methods for surveying terrestrial mammals.

[0003] Current mammal surveys primarily employ transect methods, infrared camera deployment, or drone patrols. In routine infrared camera surveys, cameras are often tied to tree trunks with cable ties or wire. However, field investigations have revealed that desert ecosystems have short vegetation, and most surveyed areas lack tall trees, making it impossible to secure infrared cameras using traditional methods. This results in poor survey coverage, omissions of animal species, and directly impacts the accuracy of the final survey results. Summary of the Invention

[0004] To achieve the above and other related objectives, the present invention discloses a fixed device for monitoring wild mammals, comprising: The system includes an adjustable angle support rod, a universal joint, a mounting platform, and an infrared camera. The mounting platform is connected to the adjustable angle support rod, the universal joint is mounted on the surface of the mounting platform, and the infrared camera is detachably mounted on top of the universal joint. The universal joint is used to adjust the mounting angle of the infrared camera.

[0005] Preferably, the adjustable angle support rod includes three arrow-shaped iron bars, which are arranged in parallel. Two of the arrow-shaped iron bars are welded together, and the third arrow-shaped iron bar is a rotatable support rod. After the three arrow-shaped iron bars are inserted into the ground, they form a stable triangular base on the ground surface.

[0006] Preferably, the adjustable angle support rod is provided with a support tube segment and an embedded tube segment in sequence above the base. The embedded tube segment and the support tube segment are slidably connected, and the support tube segment cooperates with the embedded tube segment to achieve height adjustment.

[0007] Preferably, the supporting pipe section has concave guide grooves on both sides and multiple waist-shaped holes on the guide grooves. The embedded pipe section has concave embedding grooves on both sides and multiple buckles on the embedding grooves to cooperate with the waist-shaped holes to lock the height position.

[0008] Preferably, the universal joint includes two side clamps, a fixing screw, a fixing nut, and two rotating steel balls. The rotating steel balls are located between the two side clamps, the fixing screw passes through the two side clamps, and the two rotating steel balls are tangent to each other. This is used to adjust the rotation angle of the infrared camera, and after the angle is determined, it is locked by tightening the fixing screw and the fixing nut.

[0009] Preferably, an umbrella-shaped water-blocking cover is installed above the infrared camera via a connecting rod to improve waterproofing.

[0010] Preferably, the mounting platform and the universal joint are detachably connected by a first screw.

[0011] Secondly, the present invention discloses a method for anchoring wild mammals for monitoring, comprising: By interpreting satellite images, conducting on-site surveys, and / or reviewing historical data, the topographic features, vegetation distribution features, hydrological features, and human activity features of the survey area are obtained. Based on the preliminary reconnaissance of the survey area, survey points were set up according to the activity traces of wild mammals; At the survey point, the infrared camera is mounted on the ground using the aforementioned fixing device, and the mounting height and observation angle of the infrared camera are adjusted and locked. After the infrared cameras are deployed, record their location information and assign them numbers, then start recording.

[0012] By adopting the above technical solution, and by setting an adjustable angle support rod with a stable triangular base on the ground, and using a special universal joint for infrared cameras to achieve rapid adjustment and locking of the camera angle, the infrared camera can be reliably fixed and deployed even in areas such as deserts where there are few tall trees and low vegetation. This overcomes the dependence on environmental conditions of traditional "tied-to-tree" installation. At the same time, the device is easy to carry and install without complicated tools. It can be quickly moved between different locations and the installation height, position and observation angle can be flexibly adjusted. If necessary, an umbrella-shaped water-proof cover can be added to improve waterproof adaptability, thereby improving the coverage of survey points and the integrity of monitoring data, and alleviating the problems of survey omissions and result deviations caused by insufficient points.

[0017] Preferably, the adjustable angle support rod 1 includes three arrow-shaped iron bars, which are arranged in parallel. Two of the arrow-shaped iron bars are welded together, and the third arrow-shaped iron bar is a rotatable support rod 13. After the three arrow-shaped iron bars are inserted into the ground, they form a stable triangular base on the ground surface.

[0018] In a preferred embodiment of the present invention, the two arrow-shaped iron skewers are a main iron skewer 11 and a secondary iron skewer 12. The diameter of the main iron skewer 11 is larger than that of the secondary iron skewer 12. A first connecting plate 14 is fixedly provided on the side of the main iron skewer 11, and the end of the secondary iron skewer 12 is fixedly connected to the first connecting plate 14.

A second connecting plate 15 is fixedly connected to the side of the rotating ring 16, and a rotatable support rod 13 is fixedly connected to the second connecting plate 15, so that the rotatable support rod 13 can rotate around the main iron skewer 11. In actual use, the rotatable support rod 13 can be rotated around the main iron skewer 11 according to the actual terrain, which improves the applicability.

[0019] Preferably, the adjustable angle support rod 1 is provided with a support tube section 2 and an embedded tube section 3 in sequence above the base. The embedded tube section 3 and the support tube section 2 are slidably connected, and the support tube section 2 cooperates with the embedded tube section 3 to achieve height adjustment.

[0020] Preferably, the support tube section 2 has concave guide grooves on both sides and multiple waist-shaped holes 211 are provided on the guide grooves. The embedded tube section 3 has concave embedding grooves on both sides and multiple buckles 311 are provided on the embedding grooves to cooperate with the waist-shaped holes 211 to lock the height position.

[0021] Preferably, the universal joint 4 includes two side clamps 41, a fixing screw 42, a fixing nut 43, and two rotating steel balls 44. The rotating steel balls 44 are located between the two side clamps 41, the fixing screw 42 passes through the two side clamps 41, and the two rotating steel balls 44 are tangent to each other. This is used to adjust the rotation angle of the infrared camera 9, and after the angle is determined, locking is achieved by tightening the fixing screw 42 and the fixing nut 43. In this embodiment of the invention, two fixing screws 42 are provided, one of which is tangent to the rotating steel ball 44 and compresses the rotating steel ball 44, increasing the pressure between the two rotating steel balls 44, thereby completing the positioning of the two rotating steel balls 44.

[0022] Preferably, the mounting platform 8 and the universal joint 4 are detachably connected by a first screw 10. The first screw 10 is fixedly installed on the mounting platform 8, and a sleeve that is compatible with the thread of the first screw 10 is fixedly installed on the universal joint 4.

[0023] Preferred, refer to Figure 2 In a preferred embodiment of the present invention, an umbrella-shaped water-blocking cover 5 is installed above the infrared camera 9 via a connecting rod 6 to improve waterproofing.

[0024] A circular iron plate 7 is fixedly installed at one end of the connecting rod 6 where the umbrella-shaped water-blocking cover 5 is not installed. The circular iron plate 7 is positioned between the sleeve and the nut of the first screw 10. The sleeve and the first screw 10 cooperate with each other to fix the umbrella-shaped water-blocking cover 5. When the umbrella-shaped water-blocking cover 5 is not needed, it can be disassembled in reverse, thereby improving the convenience of use.

[0025] Preferably, when the observation angle requires the installation of multiple infrared cameras 9, multiple universal joints 4 can be set on the mounting platform 8 to install multiple infrared cameras 9.

[0026] Secondly, the present invention discloses a method for anchoring wild mammals for monitoring, comprising: By interpreting satellite images, conducting on-site surveys, and / or reviewing historical data, the topographic features, vegetation distribution features, hydrological features, and human activity features of the survey area are obtained. Based on a preliminary reconnaissance of the survey area, survey points were established according to the activity traces left by wild mammals. The selection principles for survey points were proximity to water sources, open views, and proximity to human activity. These activity traces included ancestral footprint chains and feces. At the survey point, the infrared camera 9 is mounted on the ground using the aforementioned fixing device, and the mounting height and observation angle of the infrared camera 9 are adjusted and locked. After the infrared camera 9 is deployed, record its location information and assign it a number, then start recording.

[0027] Preferably, after the infrared cameras 9 are deployed, their location information is recorded, they are numbered, and recording begins. Selectable monitoring periods are 3 months and 6 months.

[0028] When monitoring begins during the animal breeding season, when animal activity is more frequent, a monitoring period of 3 months can be selected. When monitoring begins in winter or during seasons with low animal activity, a monitoring period of 6 months can be selected.

[0029] In a preferred embodiment of the invention, the survey area is located in a Gobi desert region. Through on-site reconnaissance, the vegetation type was determined to be desert vegetation. The tree layer mainly consists of Populus euphratica and Elaeagnus angustifolia, with a height of 3-5 meters. The shrub layer mainly consists of Tamarix chinensis, Calligonum mongolicum, Prickly ash, Ephedra sinica, Ephedra sinica var. mongolica, and Pseudolarix amabilis, with a height of 0.2-1.3 meters. Human activity is minimal, primarily grazing, mainly of camels. The survey area is 314 m². 2 Based on animal droppings, survey points were set up in open areas near rivers where food was plentiful.

[0030] Because the vegetation on site is short, it is not feasible to place the infrared camera 9 directly. The infrared camera 9 fixing device of the present invention is inserted into the ground. The angle between the main iron stick 11 and the rotatable support rod 13 is 60°~90°. The buckle 311 is lowered to the lowest position of the waist-shaped hole 211.

[0031] Adjust the universal joint 4 so that the horizontal angle between the infrared camera 9 and the ground is less than 90°, then tighten the fixing nut 43 and fixing screw 42 to complete the installation and fixing of the infrared camera 9.

[0032] After the infrared camera 9 was deployed, its GPS location information was recorded, the camera was numbered, and recording began. This survey was conducted during the summer, when animal activity is more frequent, and the monitoring period was three months.
