Description

Technical Field

[0001] The invention belongs to the technical field of forest monitoring, and in particular relates to a forest monitoring device based on land planning and utilization. Background Art

[0002] Forest monitoring refers to the systematic investigation, observation and analysis of the status, changes and management activities of forest resources in order to scientifically understand and grasp the current status and dynamics of forest resources and provide a basis for forest resource protection, management and decision-making.

[0003] When making land planning and utilization decisions for forest land, it is usually necessary to test the water and soil conservation capacity of the forest land, among which the pH value and water storage capacity of the soil are the more important parameters. At present, when testing the water storage capacity of forest land, humidity sensors and other instruments are generally used, and the instruments are inserted into the soil. The humidity sensors detect the humidity of the soil. This method can only detect shallow soil with low water content. When testing deeper soil with high soil water content, on the one hand, the humidity sensor is not easy to install and lay in the soil, and because the humidity sensor often needs to be equipped with an electronic control module and a power supply device, these equipment modules are placed in the forest environment for a long time and are easily damaged by animals, moisture, etc. On the other hand, the data collected by the humidity sensor cannot allow people to intuitively collect the water storage capacity parameters of the soil. The data of the humidity sensor needs to be analyzed by the module, and the results of the module analysis are compared with the existing technology to indirectly obtain the data of the soil water storage capacity. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a forest monitoring device based on land planning and utilization.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A forest monitoring device based on land planning and utilization comprises a load-bearing bottom plate and also comprises:

[0007] A lifting unit disposed on the top of the load-bearing bottom plate;

[0008] A plug-in tube is driven and connected to the lifting unit, the bottom end of the plug-in tube is connected to a cone head, a pH detection unit is arranged in the cone head, and a plurality of first through grooves penetrating into the inner cavity of the plug-in tube are arranged on the periphery of the plug-in tube;

[0009] A transparent rigid capillary fixedly penetrates the upper end of the insert tube, the lower end of the transparent rigid capillary extends into the insert tube, and a float is installed in the transparent rigid capillary, and the float slides vertically and freely in the transparent rigid capillary;

[0010] A sealing unit is connected to the lower end of the transparent rigid capillary, and the transparent rigid capillary stores a certain amount of air between the sealing unit and the float, so that the float is in a suspended state in the transparent rigid capillary.

[0011] Through the above technical scheme, the lifting unit drives the insert tube to move down and insert into the soil. After being inserted into place, the moisture in the soil will penetrate into the inner cavity of the insert tube through the first through groove and accumulate. During the accumulation process, the liquid level in the insert tube rises, and the sealing unit is activated, so that the liquid enters the transparent rigid capillary and drives out the air in the transparent rigid capillary. The air moves upward, and then drives the float to move upward in the transparent rigid capillary. By observing the position change of the float before and after the detection, the water storage capacity of the soil can be intuitively determined. The insert tube does not need to be taken out of the soil for observation. In addition, the water storage capacity of deeper soil can be detected. In addition, since the air between the sealing unit and the float is quantitative, the float can also make a larger movement range when the liquid level rises and falls slightly, so that the staff can collect and observe the water storage capacity of the soil more intuitively. In addition, there is no need for supporting power supply equipment and electronic control modules, which reduces the cost on the one hand and avoids the equipment being trampled by animals and damaged by moisture on the other hand.

[0012] Furthermore, a plurality of scale lines are provided on the periphery of the upper side of the transparent rigid capillary.

[0013] Through the above technical solution, when the float moves up and down in the transparent rigid capillary, the change value of the scale line corresponding to the position where the float is suspended can be determined as the water storage capacity of the soil. The operation is simple and the observation and collection is more intuitive.

[0014] Furthermore, a baffle is provided at the upper side opening of the transparent rigid capillary.

[0015] Through the above technical solution, the baffle limits the upward movement of the float in the transparent rigid capillary tube, thereby preventing the float from escaping from the transparent rigid capillary tube due to the tilt of the device in a non-working state.

[0016] Furthermore, the lifting unit includes two support columns vertically fixed to the top surface of the load-bearing base plate, the top ends of the two support columns are commonly fixed with a top plate, the peripheries of the two support columns are commonly sleeved with a lifting plate, the outer wall of the lifting plate is provided with a guide hole for the support columns to pass freely, the upper end of the insert tube is fixedly penetrated on the lifting plate, a bracket is fixed on the top of the lifting plate, a nut sleeve is penetrated on the top of the top plate, a lifting screw rod is coaxially threaded on the nut sleeve, and the lower end of the lifting screw rod is rotatably connected to the top of the bracket.

[0017] Through the above technical solution, when the insert tube is inserted into the soil, the lifting screw rod is manually rotated, and the lifting screw rod is screwed into the nut sleeve thread, thereby moving the driving bracket downward and causing the insert tube to move downward until the insert tube is inserted into the soil to a certain position. The operation is simple, and the insertion depth into the soil is adjustable, which is convenient for detecting the water storage capacity of soil at different depths within a certain range.

[0018] Furthermore, the sealing unit includes a fixed plug coaxially fixed to the lower inner wall of the transparent rigid capillary tube, a plurality of connecting grooves are opened on the end face of the fixed plug, a sliding rod is coaxially passed through the end face of the fixed plug, the sliding rod slides freely on the fixed plug, a blocking plug is fixed to the upper end of the sliding rod, the positive projection area of ​​the blocking plug covers the connecting groove, and a hollow float is fixed to the lower end of the sliding rod.

[0019] By means of the above technical scheme, when the liquid in the soil penetrates into the inner cavity of the insert tube from the first through groove and accumulates, during the accumulation process, the liquid level rises, thereby lifting the hollow float, and when the hollow float is lifted, the liquid surface simultaneously blocks the quantitative air inside the transparent rigid capillary to prevent air from escaping. During the process of being lifted up, the hollow float synchronously drives the stopper to move upward, so that the end face of the stopper is separated from the abutting state with the end face of the fixed plug, thereby allowing the liquid to enter the transparent rigid capillary from the connecting groove, and as the liquid level rises, the liquid will drive the quantitative air in the transparent rigid capillary upward, so that the quantitative air synchronously drives the float to move upward, thereby enabling the parameters of the soil water storage capacity to be collected more intuitively without pulling out the insert tube. When the liquid level drops, under the action of the gravity of the hollow float and the stopper, the stopper moves downward until the end face of the stopper abuts against the end face of the fixed plug, thereby blocking the quantitative air in the transparent rigid capillary to prevent the quantitative air from escaping, thereby causing the float to hover at the initial position.

[0020] Furthermore, an overflow groove is provided on the periphery of the lower end of the transparent rigid capillary tube, and the upper inner wall of the overflow groove is flush with the lower end surface of the fixed plug.

[0021] Through the above technical solution, an overflow groove is set so that when the liquid level in the inner cavity of the insert rises, the liquid can discharge the air in the transparent rigid capillary below the fixed plug through the overflow groove, thereby preventing air from entering the transparent rigid capillary and causing detection errors.

[0022] Furthermore, the lower end of the sliding rod is fixedly sleeved with a limit ring, and a light-load spring is sleeved around the periphery of the sliding rod. The two ends of the light-load spring in the elastic force direction elastically press against the upper end surface of the limit ring and the lower end surface of the fixed plug respectively.

[0023] Through the above technical solution, the light-load spring generates a downward elastic supporting force on the limit ring, so that the hollow float can move downward in time when the liquid level drops, avoiding the phenomenon of air circulation inside and outside the transparent rigid capillary.

[0024] Furthermore, the outer diameter of the upper peripheral edge of the insert tube is smaller than that of the lower peripheral edge, and the peripheral portion with the smaller outer diameter is defined as a mounting portion, and a shield is sleeved on the peripheral edge of the mounting portion, and the shield is rotatably connected to the peripheral edge of the insert tube, and the outer diameter of the shield is consistent with the outer diameter of the peripheral edge of the lower side of the insert tube, and a plurality of second through grooves are provided on the peripheral edge of the shield, and the number of the second through grooves is consistent with the number of the first through grooves, and a driven gear is fixedly sleeved on the upper end of the shield, and a timer is installed on the lifting plate, and the rotating handle of the timer is fixedly sleeved on a driving gear, and the driving gear is in meshing state with the driven gear.

[0025] Through the above technical scheme, the baffle cover is rotated at a fixed angle so that the first through groove and the second through groove are in a through state, so that the liquid in the soil can penetrate into the inner cavity of the insert tube through the first through groove and the second through groove, and when the baffle cover is rotated at a fixed angle again, the first through groove and the second through groove are in a staggered state, so that the liquid in the soil cannot continue to penetrate into the insert tube. In addition, through the setting of the timer, the baffle cover is rotated within a predetermined time, so that the first through groove and the second through groove are changed from a through state to a staggered state. At this time, the liquid in the soil cannot penetrate into the insert tube, so that the water storage capacity of the soil can be observed within a fixed time, so that the observed and collected data is more accurate, and it is convenient to compare the water storage capacity of the soil per unit time. In addition, since the timer can be automatically operated to drive the baffle cover to rotate, the first through groove and the second through groove can be changed from a through state to a staggered state without manual operation, which saves time and effort.

[0026] Furthermore, a pull rod is fixedly connected to the upper end surface of the cone head, and the upper end of the pull rod is inserted into the inner cavity of the insert tube and slides freely, a filter plate is sleeved on the periphery of the transparent rigid capillary, and the filter plate slides freely on the periphery of the transparent rigid capillary, and the upper end of the pull rod is fixedly connected to the bottom of the filter plate, the filter plate is coaxially engaged in the insert tube and slides freely in the insert tube, a sealing cover is coaxially fixedly connected to the bottom of the filter plate, the periphery of the sealing cover is in sliding contact with the inner cavity wall of the insert tube, and a receiving groove for receiving the sealing cover is provided on the inner bottom wall of the inner cavity of the insert tube, and a mud discharge port is provided on the periphery of the lower side of the insert tube.

[0027] Through the above technical solution, by setting the filter plate, the soil in the liquid that penetrates into the insert tube through the first through groove can be blocked by the filter plate, thereby preventing the soil from entering the transparent rigid capillary tube, causing the sliding of the sliding rod to be blocked and the end faces of the blocking plug and the fixed plug to be cushioned by the soil, thereby affecting the quantitative air in the transparent rigid capillary tube, thereby affecting the movement of the float in the transparent rigid capillary tube. In addition, when the insert tube is inserted into the soil, the cone head is subjected to the resistance of the soil, so that the upper end face of the cone head will be tightly against the lower end face of the insert tube, thereby making At this time, the sealing cover moves upward in the insert tube, and the sealing cover blocks the mud discharge port to prevent the liquid accumulated in the insert tube from overflowing from the mud discharge port. In addition, when the insert tube is pulled out after the detection, the resistance of the cone head disappears, and the cone head moves downward under the action of gravity, so that the cone head can drive the sealing cover to move downward, thereby opening the mud discharge port. On the one hand, the soil retained on the surface of the filter plate can contact with the liquid, and the liquid dilutes the soil. In this way, the soil and liquid can be quickly discharged from the mud discharge port by tilting the insert tube.

[0028] Furthermore, the pH detection unit includes a PH test paper placement groove opened on the top surface of the cone head, and a plurality of water seepage grooves are opened on the outer wall of the cone head, and the water seepage grooves are connected with the PH test paper placement groove.

[0029] Through the above technical solution, the staff will insert a PH test paper of a certain size into the PH test paper placement slot at the beginning of the work. As the cone head is inserted into the soil, the liquid in the soil enters the PH test paper placement slot from the seepage slot and contacts the PH test paper, thereby allowing the PH test paper to perform PH detection on the liquid in the soil. When the insert is pulled out, the pH value of the liquid in the soil can be determined by observing the color of the PH test paper.

[0030] The beneficial effects of the present invention are as follows:

[0031] (1) The present invention increases the liquid level accumulated in the inner cavity of the insert tube, thereby causing the float to move upward in the transparent rigid capillary tube, so that the staff can more intuitively collect the soil water storage capacity parameters, and can detect the water storage capacity of soil at a deeper depth. The installation is convenient and does not require supporting power supply equipment and electronic control modules. On the one hand, the cost is reduced, and on the other hand, the equipment is prevented from being trampled by animals and damaged by moisture.

[0032] (2) After the timer is set, the present invention drives the driving gear to rotate, and then the driving gear and the driven gear are meshed and transmitted, thereby driving the shield to rotate, so that the first through groove and the second through groove are changed from a through state to a staggered state, thereby realizing a visual detection of the water storage capacity in the soil within a predetermined time, saving time and labor, and the operation is convenient and does not require manual intervention;

[0033] (3) When the insert tube is inserted into the soil, the cone head is subjected to resistance from the soil, so that the upper end surface of the cone head and the lower end surface of the insert tube are tightly abutted against each other, and the sealing cover is simultaneously driven to move upward, so that the sealing cover blocks the mud discharge port. When the insert tube is pulled out of the soil, the cone head moves downward, so that the sealing cover moves downward, so that the soil on the surface of the filter plate contacts the liquid in the insert tube, so as to dilute the soil. Then, by tilting the device, the diluted soil and liquid can be quickly discharged from the mud discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Combination Figures 1 to 5 As shown, the insert tube 13 is fixedly inserted on the lifting plate 11. Specifically, a connecting section is coaxially fixed on the top of the insert tube 13, and the connecting section is inserted on the lifting plate 11. When the lifting plate 11 moves up and down, the insert tube 13 is synchronously driven to move up and down.

The periphery of the mounting portion 34 is provided with a plurality of first strip-shaped through grooves 22 in an array along the axial direction of the insert tube 13. The first through grooves 22 are connected to the inner cavity of the insert tube 13.

[0050] Combination Figures 5 to 8 As shown, a transparent rigid capillary 5 is coaxially fixedly inserted on the top of the insert tube 13, that is, on the connecting section, and the transparent rigid capillary 5 can be made of acrylic material. In addition, the lower end of the transparent rigid capillary 5 penetrates into the inner cavity of the insert tube 13, and its upper end is located above the connecting section. A float 21 is installed in the transparent rigid capillary 5, and the float 21 slides vertically and freely in the transparent rigid capillary 5. A plurality of scale lines 17 are provided from top to bottom on the upper periphery of the transparent rigid capillary 5. A fixed plug 26 is fixedly connected to the inner wall of the lower side of the transparent rigid capillary 5.

A certain amount of air is stored inside the transparent rigid capillary 5 between the fixed plug 26 and the float 21. Due to the storage of a certain amount of air, the float 21 is subjected to the buoyancy of the certain amount of air, and can be suspended on the upper side of the transparent rigid capillary 5. When the float 21 moves up and down in the transparent rigid capillary 5, the hovering position will correspond to the scale line 17. In addition, a retaining bar 29 is provided at the upper side of the transparent rigid capillary 5. In addition, an overflow groove 25 is provided at the periphery of the lower end of the transparent rigid capillary 5.

[0051] Combination Figures 4 to 5 As shown, the periphery of the mounting portion 34 is sleeved with a shield 12, and the shield 12 is rotatably connected to the periphery of the insert tube 13, and the outer diameter of the shield 12 is consistent with the outer diameter of the lower periphery of the insert tube 13, so that when the insert tube 13 is inserted into the soil, the shield 12 will not increase the resistance of the insert tube 13 into the soil, and the periphery of the shield 12 is provided with a plurality of second through slots 4, and the number of the second through slots 4 is consistent with the number of the first through slots 22. When the shield 12 is rotated to a certain angle, the first through slots 22 and the second through slots 4 will be in a through state, and the upper end of the shield 12 is fixedly sleeved with a driven gear 16, and a timer 10 is installed on the lifting plate 11, and the rotary handle of the timer 10 is fixedly sleeved with a driving gear 18, and the driving gear 18 is in a meshing state with the driven gear 16. The timer 10 is a mechanical structure, and the timer 10 is already a relatively mature structure in the prior art, such as a timing device used on an electric fan, which can be applied to this embodiment;

[0052] like Figure 4 , Figure 5 , Fig.11 and Fig.12As shown, the upper end face of the cone head 2 (i.e., the end face of the end with the largest outer diameter of the cone head 2) is symmetrically welded with two tie rods 14 along its axial direction, and the upper end of the tie rod 14 penetrates into the inner cavity of the insert tube 13 and slides freely. The peripheral edge of the transparent rigid capillary 5 is sleeved with a filter plate 23, and the filter plate 23 is used to filter the soil in the liquid, so that the liquid can penetrate the filter plate 23 and penetrate into the lower space of the inner cavity of the insert tube 13, while the soil remains on the top of the filter plate 23, and the filter plate 23 slides freely on the peripheral edge of the transparent rigid capillary 5. The upper end of the pull rod 14 is fixed to the bottom of the filter plate 23, the filter plate 23 is coaxially engaged in the insert tube 13 and slides freely in the insert tube 13, and a sealing cover 24 is coaxially fixed to the bottom of the filter plate 23. The periphery of the sealing cover 24 is in sliding contact with the inner cavity wall of the insert tube 13, and the inner bottom wall of the inner cavity of the insert tube 13 is provided with a receiving groove for accommodating the sealing cover 24. A mud discharge port 3 is provided on the lower periphery of the insert tube 13. When the cone head 2 moves downward into place, the lower inner wall of the mud discharge port 3 is flush with the upper surface of the filter plate 23.

[0053] Combination Fig.11 , Fig.12 As shown, a PH test paper placement groove 19 is provided on the top surface of the cone head 2, and two water seepage grooves 20 are provided on the outer wall of the cone head 2. The water seepage grooves 20 are connected with the PH test paper placement groove 19, so that liquid can enter the PH test paper placement groove 19 through the water seepage grooves 20.

[0054] The working principle of this embodiment is as follows:

[0055] Place the pH test paper: In the initial state, the insert 13 is in Figure 1 Position, at this time, under the action of gravity, the cone head 2 will move downward, and the cone head 2 and the insert tube 13 will be separated, and the staff will insert a pH test paper of a certain size into the pH test paper placement slot 19. After the pH test paper is placed in the pH test paper placement slot 19, the end of the pH test paper will not be exposed from the pH test paper placement slot 19;

[0056] Lower the insert 13: Place the load-bearing base plate 1 on the surface to be tested, manually rotate the lifting screw 7, the lifting screw 7 is screwed into the nut sleeve 8, and then the driving bracket 9 is moved downward, and the insert 13 is moved downward until the insert 13 is inserted into the soil to a certain position;

[0057] When the insert 13 is inserted into the soil, the cone head 2 is subjected to resistance from the soil, so that the upper end surface of the cone head 2 will be tightly against the lower end surface of the insert 13, thereby causing the sealing cover 24 to move upward in the insert 13 and cover the mud discharge port 3;

[0058] Water storage detection: manually rotate the handle of the timer 10 so that the handle indicates the appropriate time scale on the timer 10 (such as 60 minutes, 90 minutes, etc.). At this time, the timer 10 starts to work, and the handle slowly drives the driving gear 18 to rotate, and then drives the shield 12 to rotate slowly through the meshing transmission of the driving gear 18 and the driven gear 16, that is, the first through groove 22 and the second through groove 4 begin to change from a through state to a staggered state, and the liquid in the soil penetrates into the insert tube 13 from the second through groove 4 and the first through groove 22 in turn, and the soil mixed in the liquid will be blocked by the filter plate 23, so that the liquid penetrates through the filter plate 23 and penetrates into the lower space of the inner cavity of the insert tube 13, and begins to accumulate. During the accumulation process, the liquid level rises, and the rising liquid level can lift up the hollow float 28. When the hollow float 28 is lifted up, the liquid surface simultaneously blocks the quantitative air inside the transparent rigid capillary 5 to prevent air from escaping. The hollow float When 28 is lifted up and moved upward, the stopper 27 is synchronously driven upward, so that the end face of the stopper 27 is separated from the state of abutment with the end face of the fixed plug 26, so that the liquid can enter the transparent rigid capillary 5 from the connecting groove 33, and as the liquid level rises, the liquid will drive the quantitative air in the transparent rigid capillary 5 upward, so that the quantitative air synchronously drives the float 21 to move upward. When the float 21 moves up and down in the transparent rigid capillary 5, the change value of the scale line 17 corresponding to the suspended position can be determined as the water storage capacity of the soil, so that the parameters of the soil water storage capacity can be collected more intuitively without pulling out the insert 13. As the active gear 18 rotates, the active gear 18 drives the driven gear 16 to engage the transmission, so that the stopper 12 rotates until the first through groove 22 and the second through groove 4 are in a staggered state. At this time, the liquid in the soil cannot continue to penetrate into the insert 13, so as to complete the soil water storage capacity detection within the specified time;

[0059] Take out the insert 13 and discharge the mud: rotate the lifting screw 7 in the opposite direction, so that the lifting plate 11 moves upward. When moving upward, the resistance of the cone head 2 disappears. Under the action of gravity, the cone head 2 moves downward, so that the cone head 2 can drive the sealing cover 24 to move downward, thereby moving the filter plate 23 downward, and allowing the liquid in the inner cavity of the insert 13 to reversely penetrate the filter plate 23 and contact the soil retained on the surface of the filter plate 23, thereby diluting the soil. When the sealing cover 24 moves downward into place, the shielding effect of the sealing cover 24 on the mud discharge port 3 disappears, thereby opening the mud discharge port 3, and then by tilting the support column 15 or the insert 13 in the device, the soil and liquid are quickly discharged from the mud discharge port 3.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
