Description

Technical Field

[0001] The present invention relates to the technical field of forestry environment monitoring equipment, and more specifically, to a forestry environment monitoring equipment and method. Background Art

[0002] At present, forestry environment monitoring equipment is mainly used to monitor environmental parameters in the forest in real time, such as temperature, humidity, light intensity, soil temperature and humidity, CO2 concentration, etc., so that forestry managers can better understand and master the growth status and environmental changes of the forest. However, most of the existing monitoring equipment adopts a fixed installation method, and the installation process is complex. The existing equipment is not convenient enough during the installation and disassembly process, which affects the efficiency of the monitoring work. For example, a forestry environment monitoring equipment with the application number CN202122282185.8 includes a protective frame and a cover plate. In the middle of the bottom end inside the protective frame, a processing mechanism is fixedly arranged. In the middle of the bottom end on the right side of the protective frame, a notch is opened and a charging head is fixedly arranged inside the notch. The charging head is electrically connected to the processing mechanism through a wire. On the lower middle parts around the outside of the protective frame, rotating grooves are opened. When the protective frame is used outdoors, the solar panels installed around the outside of the protective frame can be pulled in turn through the installation shaft, and the solar panels can be at a ninety-degree structure with the protective frame. According to the irradiation angle of the sun, the angle of the solar panels can be adjusted through the rotating grooves and rotating blocks for power generation. Then, the electric energy generated by the solar panels is collected inside the processing mechanism. After the power source is used up, it can be charged through the charging head. Moreover, the solar panels are all in a folded structure, which can increase the contact area with sunlight and improve the power generation efficiency. And a forestry ecological environment monitoring equipment based on the Internet of Things with the application number CN202122662494.8, which relates to the technical field of ecological environment monitoring, includes a support column, an outer support protection support device and a bottom sleeve foot support device. An outer support protection support device is movably lapped on the outer surface of the middle part of the support column. A bottom sleeve foot support device is movably sleeved on the bottom end of the support column. A hydraulic device is fixedly connected to the inner surface of the outer support protection support device. By passing the outer support protection support device through the support column, and the fitting block can contact the surface of the support column, the support legs can be pulled and extended on the outer surface of the rotating roller, and the foot pads can be fixed on the surface of the land for support. It has the characteristics of protecting the outer surface of the support column and reducing shaking, solves the problem that the support column will tilt with the wind, and achieves the effect of protecting the outer surface of the support column and reducing shaking. The above-mentioned equipment is all large in volume, not easy to disassemble and move, and the installation is relatively complex, and they are all placed on the ground. The area that needs to be monitored in forestry is relatively large, and detection equipment needs to be installed in multiple places. If the installation efficiency is low, it will affect the installation in a large area. The possibility of being damaged by various animals is relatively large, and the influence of rainwater accumulation and the like is relatively large. This is the deficiency of the existing technology. Summary of the Invention

[0004] A forestry environment monitoring device includes a connecting frame, characterized in that: the outer end of the upper side of the connecting frame is connected with a trunk surrounding component. The trunk surrounding component includes a semi-circular arc-shaped bracket. The center of the bracket fixes the connecting frame.

The upper side of each L-shaped ear block is respectively fixedly connected with a U-shaped connecting block. Each U-shaped connecting block is respectively hinged with a swing rod. The upper side of the inner end of each swing rod is serrated. The lower side of the inner end of each swing rod is respectively fixed to the vertical surface of the L-shaped ear block through a spring. The outer end of each swing rod is respectively fixedly connected with a limiting ring. Each limiting ring corresponds to one of the limiting shafts one by one. The limiting shaft can be inserted into the limiting ring, and the limiting ring can pass through the limiting hole on the L-shaped ear block.

[0005] The outer end of the lower side of the connecting frame is connected with a sensor box limiting component, and the sensor box limiting component is cooperatively connected with the sensor box.

[0006] As a further limitation of this technical solution, the sensor box limiting component includes a cylinder, a fixing rod, a fixing frame, an L-shaped swing arm, a chute, a cross-shaped moving shaft, a spring support rod, a second spring, a sensor box limiting plate, a card slot, a bottom plate and a limiting post. The cylinder is fixed at one end of the upper side of the fixing frame. The upper side of the fixing frame fixes the outer end of the lower side of the connecting frame. The lower end of the fixing frame fixes the fixing rod. The two ends of the fixing rod are respectively rotatably connected to the bent parts of the L-shaped swing arms. The lower end of each L-shaped swing arm is respectively fixedly connected to one end of the lower side of the sensor box limiting plate. A card slot is respectively opened in the middle of each sensor box limiting plate. A vertical plate is respectively arranged in each card slot. The vertical plates are respectively fixed on both sides of the sensor box.

[0007] As a further limitation of this technical solution, a chute is respectively opened at the upper end of each L-shaped swing arm. The horizontal axis ends of the cross-shaped moving shaft are respectively arranged in the two card slots. The upper side of the vertical shaft of the cross-shaped moving shaft is inserted into the cylinder and matches the cylinder.

[0008] As a further limitation of the technical solution, the vertical shaft of the cross-shaped moving shaft passes through the center of the fixed rod and the second spring, the lower end of the vertical shaft of the cross-shaped moving shaft is fixed to the upper side of the spring support rod, the lower end of the spring support rod is fixed to the upper side of one end of the bottom plate, the upper end of the second spring is fixed to the fixed rod, and the lower end of the second spring is fixed to the spring support rod.

[0009] As a further limitation of the technical solution, a plurality of uniformly arranged limiting columns are fixed to the upper side of the bottom plate, a plurality of limiting holes are provided on the lower side of the sensor box, the limiting columns and the limiting holes correspond one by one, and the limiting columns can be inserted into the limiting holes.

[0010] As a further limitation of the technical solution, when the limiting holes are completely matched with the limiting columns, the upper horizontal plate of the sensor box limiting plate can be stuck on the upper side of the sensor box, and the vertical surface of the limiting plate fits the vertical surface of the sensor box.

[0011] The present invention also provides a usage method of a forestry environment monitoring device, which specifically includes the following steps:

[0012] Step 1: First, install the connecting frame and the sensor box limiting component on the tree trunk through the tree trunk surrounding component;

[0013] Step 2: Connect the sensor box and the sensor box limiting component to complete the installation of the sensor box.

[0014] Among them, in Step 1, by pulling the tree trunk surrounding plate to surround the tree trunk, inserting the limiting shaft into the limiting ring, and passing the limiting shaft through the central through hole of the L-shaped ear block, at this time the spring undergoes elastic deformation. The inner end of the swing rod is inclined and serrated with a sharp surface, which can slightly be stuck into the tree trunk surface to achieve stable support, and install the connecting frame and the tree trunk surrounding component on the tree trunk. The tree trunk surrounding component is connected to the sensor box limiting component to complete the installation and fixation of the sensor box limiting component.

[0015] Among them, in Step 2, the initial state of the sensor box limiting plate is as shown in the figure. At this time, the upper side of the sensor limiting plate is in an outward-opening state, and the second spring is not stressed in its initial state. After aligning the vertical plate of the sensor box with the card slot, place the sensor box between the two sensor box limiting plates. After placing the sensor box, at this time, each limiting hole corresponds to a limiting post one by one. Under the action of gravity, the sensor box moves downward. The downward movement of the sensor box drives the lower side of the sensor limiting plate to swing outward, thereby driving the L-shaped swing arm to swing. The L-shaped swing arm drives the cross-shaped moving shaft to move downward. As the cross-shaped moving shaft moves downward, the cross-shaped moving shaft drives the bottom plate and the spring support rod to move downward. The second spring is stretched, and the upper side of the sensor box limiting plate gradually swings inward until the upper horizontal plate of the sensor box limiting plate is stuck on the upper side of the sensor box, and the limiting post is completely inserted into the limiting hole, and the vertical plate is in the card slot. Due to the combined limiting action of the sensor box limiting plate, the limiting post and the limiting hole, the vertical plate and the card slot, the sensor box is completely fixed.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] By using the cooperative connection between the sensor box limiting component and the sensor box, through the combined limiting action of the sensor box limiting plate, the limiting post and the limiting hole, the vertical plate and the card slot, the complete fixation of the sensor box is realized. Without any power, relying on gravity, and relying on the swing of the limiting post and the limiting hole, the vertical plate and the card slot under the action of gravity to achieve installation. After installation, automatic locking is achieved in all directions of up, down, left, right, front, and back;

[0018] The U-shaped connecting blocks are respectively hinged to the middle positions of the swing rods. The upper sides of the inner ends of each swing rod are serrated. The outer ends of the swing rods are respectively fixedly connected with limiting rings. The limiting shaft passes through the central through hole of the L-shaped ear block. Under the action of gravity, the outer ends of the swing rods are pressed down, and the inner ends of the swing rods swing inward and are stuck into the surface of the tree trunk. They are pressed in by gravity, and the greater the gravity, the tighter they are pressed in. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following further describes the present invention in conjunction with the appended Figures 1-6 drawings and embodiments.

[0028] A forestry environment monitoring device includes a connecting frame 1. The outer end of the upper side of the connecting frame 1 is connected to a trunk surrounding component 2. The trunk surrounding component includes a semi-circular bracket 28. The center of the bracket 28 fixes the connecting frame 1. The two ends and the middle part of the bracket 28 are respectively fixedly connected with limit shafts 21. The lower side of the bracket 28 is provided with an elastic superior arc-shaped trunk surrounding plate 26.

The limit shaft 21 can be inserted into the limit ring 22, and the limit ring 22 can pass through the limit hole on the L-shaped ear block 23;

[0029] The outer end of the lower side of the connecting frame 1 is connected to the sensor box limiting component 3, and the sensor box limiting component 3 is cooperatively connected to the sensor box 4.

[0030] In this embodiment, the bracket 28 is stuck on the tree trunk. By pulling the tree trunk surrounding plate 26 to surround the tree trunk, the limiting shaft 21 is inserted into the limiting ring 22, and the limiting shaft 21 passes through the central through hole of the L-shaped ear block 23. At this time, the spring 24 undergoes elastic deformation. The inner end of the swing rod 29 is inclined and serrated with a sharp surface, and can be slightly stuck into the surface of the tree trunk to achieve stable support, realizing the installation of the connecting frame 1 and the tree trunk surrounding component 2 on the tree trunk. The tree trunk surrounding component 2 is connected to the sensor box limiting component 3, realizing the installation and fixation of the sensor box limiting component 3.

[0031] The sensor box limiting component 3 includes a cylinder 38, a fixing rod 31, a fixing frame 37, an L-shaped swing arm 35, a chute 351, a cross-shaped moving shaft 381, a spring support rod 33, a second spring 32, a sensor box limiting plate 36, a card slot 361, a bottom plate 34, and a limiting post 341. The cylinder 38 is fixed at one end of the upper side of the fixing frame 37. The upper side of the fixing frame 37 is fixed to the outer end of the lower side of the connecting frame 1. The lower end of the fixing frame 37 is fixed to the fixing rod 31. The two ends of the fixing rod 31 are respectively rotatably connected to the bent parts of the L-shaped swing arms 35. The lower ends of each L-shaped swing arm 35 are respectively fixedly connected to one end of the lower side of the sensor box limiting plate 36. Each sensor box limiting plate 36 is respectively provided with the card slot 261 in the middle. Each card slot 361 is respectively provided with a vertical plate 41, and the vertical plates 41 are respectively fixed on both sides of the sensor box 4.

[0032] Each upper end of the L-shaped swing arm 35 is respectively provided with the chute 351. The two ends of the horizontal axis of the cross-shaped moving shaft 381 are respectively arranged in the two card slots 351. The upper side of the vertical axis of the cross-shaped moving shaft 381 is inserted into the cylinder 38 and is matched with the cylinder 38.

[0033] The vertical axis of the cross-shaped moving shaft 381 passes through the center of the fixing rod 31 and the second spring 32. The lower end of the vertical axis of the cross-shaped moving shaft 381 is fixed to the upper side of one end of the spring support rod 33. The lower end of the spring support rod 33 is fixed to the upper side of one end of the bottom plate 34. The upper end of the second spring 32 is fixed to the fixing rod 31, and the lower end of the second spring 32 is fixed to the spring support rod 33.

[0034] A plurality of uniformly arranged limiting posts 341 are fixed on the upper side of the bottom plate 34. A plurality of limiting holes 42 are arranged on the lower side of the sensor box 4. The limiting posts 341 and the limiting holes 42 correspond one by one, and the limiting posts 341 can be inserted into the limiting holes 42.

[0035] When the limiting hole 42 is fully engaged with the limiting post 341, the upper horizontal plate of the sensor box limiting plate 36 can be stuck on the upper side of the sensor box 4, and the vertical surface of the limiting plate 36 fits against the vertical surface of the sensor box 4.

[0036] In this embodiment, a storage battery, a GPS positioning module, a communication module, a storage module, and various kinds of sensors should be provided. The following are some common sensors and their functions:

[0037] Temperature and humidity sensor: It is used to monitor the temperature and humidity in the forest area. This kind of sensor can obtain the climate data of the forest area in real time and provide suitable environmental conditions for the growth of forest trees. For example, the SHT11 type temperature and humidity sensing chip launched by Sensirion Company in Switzerland has high precision, high integration and strong anti-interference ability.

[0038] Light intensity sensor: It is used to monitor the light intensity. This kind of sensor can help forestry managers understand the light conditions in the forest area, so as to select suitable cultivation areas and planting schemes and improve the growth quality of forest trees. The BH1750FVI high-precision digital light intensity sensor launched by RHOM Co., Ltd. in Japan supports a large range of light intensity changes and meets the requirements of light intensity monitoring in the forest area.

[0039] Soil temperature and humidity sensor: It is used to monitor the soil humidity and temperature in real time. This kind of sensor can help forestry managers understand the soil conditions, guide reasonable fertilization and irrigation, and improve the growth efficiency of forest trees. For example, the JTS-01 type soil temperature and soil moisture sensor produced by Beijing Kunlun Coast Company is a commonly used soil temperature and humidity monitoring device.

[0040] CO2 sensor: By measuring the concentration of CO2 in the air, it reflects the photosynthesis and respiration in the process of forest tree growth. This kind of sensor can help forestry managers understand the carbon cycle situation in the forest area and provide a basis for forest carbon sink management.

[0041] Rainfall sensor: It is used to monitor the rainfall in the forest area. This kind of sensor can help forestry managers understand the water resource situation in the forest area and guide reasonable water use and flood control and drought relief work.

[0042] In addition, wind speed and direction sensors, water quality monitoring sensors, etc. may also be used in forestry environment monitoring to comprehensively understand the environmental conditions in the forest area. These sensors can, through the layout of intelligent sensor nodes, monitor environmental factors such as temperature, humidity, and light in real time, and accurately locate the monitoring data to each sensor. These data not only provide forestry managers with a comprehensive understanding of the forest land environment, but also help them accurately grasp key information such as the growth status and pest and disease situation of the forest land, providing strong support for forestry resource management, forest fire prevention, disaster monitoring and other work.

[0043] In this embodiment, the initial state of the sensor box limiting plate 36 is as follows Figure 1 shown. At this time, the upper side of the sensor limiting plate 36 is in an outwardly opened state, and the second spring 32 is not stressed in its initial state. After aligning the vertical plate 41 of the sensor box 4 with the card slot 361, place the sensor box 4 between the two sensor box limiting plates 36. After placing the sensor box 4, at this time, each limiting hole 42 corresponds to a limiting post 341 one by one. Under the action of gravity, the sensor box 4 moves downward. The downward movement of the sensor box 4 drives the lower side of the sensor limiting plate 36 to swing outward, thereby driving the L-shaped swing arm 35 to swing. The L-shaped swing arm 35 drives the cross-shaped moving shaft 381 to move downward. When the cross-shaped moving shaft 381 moves downward, the cross-shaped moving shaft 381 drives the bottom plate 34 and the spring support rod 33 to move downward, the second spring 32 is stretched, and the upper side of the sensor box limiting plate 36 gradually swings inward until the upper horizontal plate of the sensor box limiting plate 36 is stuck on the upper side of the sensor box 4. At this time, as shown in Figure 4 shown, the limiting post 341 is completely inserted into the limiting hole 42, and the vertical plate 41 is in the card slot 361. Due to the combined limiting effect of the sensor box limiting plate 36, the limiting post 341 and the limiting hole 42, the vertical plate 41 and the card slot 361, the sensor box 4 is completely fixed.

[0044] During disassembly, it is also very convenient. As long as the upper side of the sensor box limiting plate 36 is pulled open to release the sensor box 4, the sensor box 4 can be taken away.

[0045] During use, first install the connecting frame 1 and the sensor box limiting component 3 on the tree trunk through the tree trunk surrounding component 2, and then connect the sensor box 4 and the sensor box limiting component 3 to complete the installation of the sensor box 4.

[0046] The present invention also provides a method for using a forestry environment monitoring device, which specifically includes the following steps:

[0047] Step 1: First install the connecting frame 1 and the sensor box limiting component 3 on the tree trunk through the tree trunk surrounding component 2;

[0048] Step 2: Connect the sensor box 4 and the sensor box limiting component 3 to complete the installation of the sensor box 4.

[0049] Among them, in Step 1, by pulling the tree trunk surrounding plate 26 to open it so that it surrounds the tree trunk, the limiting shaft 21 is inserted into the limiting ring 22, and the limiting shaft 21 passes through the central through hole of the L-shaped ear block 23. At this time, under the action of gravity, the spring 24 undergoes elastic deformation. The inner end of the swing rod 29 is inclined and serrated and has a sharp surface, which can be slightly stuck into the tree trunk surface to achieve stable support, thereby realizing the installation of the connecting frame 1 and the tree trunk surrounding component 2 on the tree trunk. The tree trunk surrounding component 2 is connected to the sensor box limiting component 3 to realize the installation and fixation of the sensor box limiting component 3.

[0050] Among them, in step two, after aligning the vertical plate 41 of the sensor box 4 with the card slot 361, the sensor box 4 is placed between the two sensor box limit plates 36. After placing the sensor box 4, at this time, each limit hole 42 corresponds to a limit post 341 one by one. Under the action of gravity, the sensor box 4 moves downward. The downward movement of the sensor box 4 drives the lower side of the sensor limit plate 36 to swing outward, thereby driving the L-shaped swing arm 35 to swing. The L-shaped swing arm 35 drives the cross-shaped moving shaft 381 to move downward. When the cross-shaped moving shaft 381 moves downward, the cross-shaped moving shaft 381 drives the bottom plate 34 and the spring support rod 33 to move downward. The second spring 32 is stretched, and the upper side of the sensor box limit plate 36 gradually swings inward until the upper horizontal plate of the sensor box limit plate 36 is stuck on the upper side of the sensor box 4. At this time, as Figure 4 shown, the limit post 341 is completely inserted into the limit hole 42, and the vertical plate 41 is in the card slot 361. Due to the combined limiting effect of the sensor box limit plate 36, the limit post 341 and the limit hole 42, the vertical plate 41 and the card slot 361, the sensor box 4 is completely fixed.

[0051] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.

The method for using a forestry environment monitoring device according to claim 7, wherein: In step one, the trunk embracing plate (26) is pulled open to make it embrace the trunk, the limiting shaft (21) is inserted into the limiting ring (22), and the limiting shaft (21) passes through the central through hole of the L-shaped ear block (23). At this time, the spring (24) undergoes elastic deformation, the inner end of the swing rod (29) is inclined and serrated with a sharp surface, and can be inserted into the surface of the trunk to achieve stable support, so that the connecting frame (1) and the trunk embracing component (2) are installed on the trunk, and the trunk embracing component (2) is connected to the sensor box limiting component (3) to achieve installation and fixation of the sensor box limiting component (3).

9. The method for using a forestry environment monitoring device according to claim 7, wherein: In step 2, the upper side of the sensor box limit plate (36) is initially opened outward, and the spring 2 (32) is initially free of force, so that the vertical plate (41) of the sensor box (4) is aligned with the card slot (361), and then the sensor box (4) is placed between the two sensor box limit plates (36). The sensor box (4) is placed properly. At this time, each limit hole (42) corresponds to the limit column (341) one by one. Under the action of gravity, the sensor box (4) moves downward, and the downward movement of the sensor box (4) drives the lower side of the sensor limit plate (36) to swing outward, thereby driving the L-shaped swing arm (35) to swing, and the L-shaped swing arm (35) drives the cross-shaped moving shaft (381). The cross-shaped movable shaft (381) moves downward, and the cross-shaped movable shaft (381) drives the bottom plate (34) and the spring support rod (33) to move downward, and the spring second (32) is stretched, and the upper side of the sensor box limit plate (36) gradually swings inward until the upper side horizontal plate of the sensor box limit plate (36) is stuck on the upper side of the sensor box (4), the limit column (341) is completely inserted into the limit hole (42), and the vertical plate (41) is in the slot (361). Due to the common limiting effect of the sensor box limit plate (36), the limit column (341) and the limit hole (42), the vertical plate (41) and the slot (361), the sensor box (4) is completely fixed.
