Description

Technical Field

[0001] This utility model relates to the field of forestry planning equipment technology, specifically a benchmark for forestry planning. Background Technology

[0002] The benchmark for forestry planning is a professional surveying tool that combines height adjustment, stable fixation, and multi-functional auxiliary design. It aims to improve the accuracy and efficiency of forestry surveying, topographical exploration, and other work, and provide reliable data support for forestry resource management, ecological restoration, and industrial planning.

[0003] In the prior art, patent CN221404303U discloses a marker pole for forestry planning, including an adjustment component. The outer wall of the adjustment component is provided with a stabilizing component. The adjustment component includes a first pole, two guide rods symmetrically installed below the first pole, a protective cylinder provided on the outer wall of the first pole, a lead screw penetrating inside the first pole, a cross handle installed above the lead screw, a nut pair connected to the outer wall of the lead screw, and a second pole connected to the outer wall of the nut pair.

[0004] There are some problems with this type of marker post used for forestry planning. For example, the grounding of the marker post is achieved by inserting a single vertical cone into the ground, which limits the vertical restraint effect between the marker post and the ground and affects the support stability of the marker post. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a benchmark for forestry planning. A screw mechanism drives vertical and diagonal gripping ribs to be inserted into the ground at the same time. The diagonal gripping ribs provide diagonal support for the benchmark and improve the vertical constraint between the ground and the benchmark, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marker for forestry planning, comprising a marker tube, an adjusting tube slidably connected inside the marker tube, and a ground-gripping mechanism;

[0007] Ground gripping mechanism: It includes a base plate, vertical gripping ribs and inclined gripping ribs. The base plate is located at the lower end of the adjusting cylinder. The interior of the base plate has evenly distributed inclined sliding openings, and inclined gripping ribs are slidably connected inside each inclined sliding opening. The interior of the base plate also has evenly distributed vertical sliding openings, and vertical gripping ribs are slidably connected inside each vertical sliding opening. A screw mechanism pushes the vertical gripping ribs and inclined gripping ribs to insert into the ground simultaneously. The inclined gripping ribs provide diagonal support for the marker and increase the vertical constraint force between the ground and the marker.

[0008] Furthermore, the gripping mechanism also includes an adjusting disc, a fixing screw, an internal threaded cylinder, a sliding groove, and a sliding seat. The fixing screw is fixedly connected to the lower end of the adjusting cylinder. The outer surface of the fixing screw is threadedly connected to the internal threaded cylinder. The lower end of the outer surface of the internal threaded cylinder is rotatably connected to the adjusting disc. The adjusting disc has evenly distributed sliding grooves inside. Each sliding groove is slidably connected to a sliding seat. The lower end of each sliding seat is rotatably connected to the upper end of an adjacent inclined gripping rib via a pin. The upper end of each vertical gripping rib is fixedly connected to the lower end of the adjusting disc, providing driving force for the movement of the vertical and inclined gripping ribs.

[0009] Furthermore, a mounting plate is fixedly connected to the upper end of the outer surface of the marker tube, and a support frame is connected to the upper end of the mounting plate by evenly distributed bolts. A positioning device is installed at the upper end of the support frame to record the geographical location of the marker in real time.

[0010] Furthermore, a screw is rotatably connected inside the marking cylinder, and an internal thread is provided inside the adjusting cylinder, which is threadedly connected to the screw. A knob is fixedly connected to the upper end of the screw to provide driving force for adjusting the position of the adjusting cylinder.

[0011] Furthermore, the outer arc surface of the adjusting cylinder is fixedly connected with uniformly distributed guide ribs, and the inner arc surface of the marking cylinder is provided with uniformly distributed rib grooves. The guide ribs are all slidably connected to the radially adjacent rib grooves, providing sliding support and guiding limit for the movement of the adjusting cylinder.

[0012] Furthermore, a scale bar is provided at the left end of the outer arc surface of the adjusting cylinder. The scale bar works in conjunction with the lower end face of the marking cylinder to display the real-time distance between the upper surface of the marking cylinder and the lower surface of the base plate.

[0013] Furthermore, the outer surface of the marking tube is provided with evenly distributed reflective strips, making the marking tube easy to identify.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This benchmark for forestry planning has the following advantages:

[0015] The vertical movement of the adjustment disc is achieved by a screw mechanism. When the adjustment disc moves downward, it pushes the vertical and diagonal gripping ribs to insert into the ground simultaneously. The diagonal gripping ribs provide diagonal support for the marker and increase the vertical constraint between the ground and the marker. When the adjustment disc moves upward, it drives the vertical and diagonal gripping ribs to move upward, thereby converging the vertical and diagonal gripping ribs and facilitating quick connection and disassembly of the marker and the ground.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a benchmark for forestry planning, including a marker cylinder 1, an adjusting cylinder 2 slidably connected inside the marker cylinder 1, and a ground-gripping mechanism 3;

[0023] The gripping mechanism 3 includes a base plate 31, vertical gripping ribs 37, and inclined gripping ribs 38. The base plate 31 is located at the lower end of the adjusting cylinder 2. The interior of the base plate 31 is provided with evenly distributed inclined sliding openings, and the inclined gripping ribs 38 are slidably connected inside the inclined sliding openings. The interior of the base plate 31 is provided with evenly distributed vertical sliding openings, and the vertical gripping ribs 37 are slidably connected inside the vertical sliding openings.

[0024] The gripping mechanism 3 also includes an adjusting disc 32, a fixing screw 33, an internal threaded cylinder 34, a sliding groove 35, and a sliding seat 36. The fixing screw 33 is fixedly connected to the lower end of the adjusting cylinder 2. The outer surface of the fixing screw 33 is threadedly connected to the internal threaded cylinder 34. The lower end of the outer surface of the internal threaded cylinder 34 is rotatably connected to the adjusting disc 32. A bellows is rotatably connected between the upper end of the internal threaded cylinder 34 and the lower end of the adjusting cylinder 2, and between the lower end of the internal threaded cylinder 34 and the upper surface of the base plate 31, through a rotating ring. During the adjustment of the adjusting disc 32, the bellows will not rotate with the internal threaded cylinder 34 during rotation, and will not obstruct the position adjustment of the adjusting disc 32. At the same time, it provides sealing protection for the fixing screw 33 to prevent external impurities from affecting the threaded connection effect between the fixing screw 33 and the internal threaded cylinder 34.

[0025] The adjusting disc 32 has evenly distributed grooves 35 inside, and each groove 35 has a sliding seat 36 slidably connected inside. The lower end of each sliding seat 36 is rotatably connected to the upper end of the adjacent inclined gripping rib 38 via a pin. The upper end of each vertical gripping rib 37 is fixedly connected to the lower end of the adjusting disc 32, bringing the lower surface of the base plate 31 into contact with the ground. Then, the internal threaded cylinder 34 is rotated. Under the action of the fixing screw 33, the internal threaded cylinder 34 moves downward. Under the limiting action of the vertical gripping rib 37 and the inclined gripping rib 38, the adjusting disc 32 will not rotate with the internal threaded cylinder 34. At the same time, the downward movement of the internal threaded cylinder 34 causes the adjusting disc 32 to move downward. The downward movement causes the three vertical gripping ribs 37 to move downwards. The three vertical gripping ribs 37 slide downwards inside their corresponding vertical sliding openings, and the lower ends of the three vertical gripping ribs 37 insert into the ground. At the same time, the downward movement of the adjusting plate 32 pushes the three oblique gripping ribs 38 to move. The three oblique gripping ribs 38 slide downwards inside their corresponding oblique sliding openings, and the lower ends of the three oblique gripping ribs 38 insert obliquely into the ground. At the same time, the downward movement of the three oblique gripping ribs 38 causes the adjacent sliding seats 36 to slide inside their corresponding sliding grooves 35. The oblique gripping ribs 38 provide oblique support for the marker pole and improve the vertical constraint between the ground and the marker pole, further improving the support stability of the marker pole.

[0026] The upper end of the outer surface of the marker cylinder 1 is fixedly connected to the mounting plate 6. The upper end of the mounting plate 6 is connected to the support frame 7 by evenly distributed bolts. The upper end of the support frame 7 is equipped with a positioning device 8, which can be a G659. The support frame 7 is placed on the upper end of the mounting plate 6, and then the support frame 7 and the mounting plate 6 are stably connected by screws to achieve stable installation of the positioning device 8. Then, the positioning device 8 is started. The space satellites of the GPS system continuously send signals to the earth. These signals contain the satellite's position information and transmission time. The positioning device 8 receives signals from at least 4 satellites. By measuring the signal propagation time, that is, the difference between the time of receiving the signal and the initial time of transmission, and combining it with the speed of light, the distance between the positioning device and each satellite is calculated. Then, the positioning device 8 corrects the error caused by external interference during signal transmission through its own algorithm and model, thereby obtaining more accurate distance information. The positioning device 8 uses the known coordinates of at least 4 satellites and the measured distance, and calculates the three-dimensional coordinates of the marker through the principle of three-dimensional spatial resection, and sends the three-dimensional coordinates of the marker to the signal receiving end of the external control and management platform in real time.

[0027] The internal structure of the marking cylinder 1 is rotatably connected to a screw 4. The internal structure of the adjusting cylinder 2 is provided with an internal thread, which is threadedly connected to the screw 4. The screw 4 is located inside the sealed space formed by the marking cylinder 1 and the adjusting cylinder 2. External impurities will not affect the transmission effect of the screw 4. The upper end of the screw 4 is fixedly connected to a knob 5. The outer arc surface of the adjusting cylinder 2 is fixedly connected with evenly distributed guide ribs 9. The inner arc surface of the marking cylinder 1 is provided with evenly distributed rib grooves. The guide ribs 9 are all slidably connected to the radially adjacent rib grooves. According to the actual support height required by the positioning device 8, the knob 5 is rotated. The rotation of the knob 5 drives the screw 4 to rotate. Since the guide ribs 9 on the outer surface of the adjusting cylinder 2 are all slidably connected to the adjacent rib grooves, they provide guidance and limit for the adjusting cylinder 2. As a result, the adjusting cylinder 2 moves downward under the action of the screw 4. The guide ribs 9 on the outer surface of the adjusting cylinder 2 slide downward inside the adjacent rib grooves. The downward movement of the adjusting cylinder 2 drives the gripping mechanism 3 to move downward. When the support height reaches the specified value, the knob 5 is stopped.

[0028] Wherein: A scale bar 10 is provided on the left end of the outer arc surface of the adjusting cylinder 2. The scale bar 10 and the lower end surface of the marking cylinder 1 are used together. The scale inside the scale bar 10 and the lower end surface of the marking cylinder 1 are at the same level, which is the real-time distance between the upper surface of the marking cylinder 1 and the lower surface of the base plate 31 in the current state.

[0029] Among them, the outer surface of the marker tube 1 is provided with evenly distributed reflective strips 11, making the marker easier to spot in the field.

[0030] The working principle of the benchmark for forestry planning provided by this utility model is as follows: During operation, the operator rotates the knob 5 according to the actual support height required by the positioning device 8. The rotation of the knob 5 drives the screw 4 to rotate. Since the guide ribs 9 on the outer surface of the adjusting cylinder 2 are all slidably connected to the adjacent rib grooves, they provide guidance and limit for the adjusting cylinder 2. As a result, the adjusting cylinder 2 moves downward under the action of the screw 4. The guide ribs 9 on the outer surface of the adjusting cylinder 2 slide downward inside the adjacent rib grooves. The downward movement of the adjusting cylinder 2 drives the ground gripping mechanism 3 to move downward. The scale inside the scale bar 10 is at the same level as the lower end face of the marking cylinder 1, which represents the real-time distance between the upper surface of the marking cylinder 1 and the lower surface of the base plate 31 in the current state. When the support height reaches the specified number of... When the position is reached, stop rotating knob 5, then place support frame 7 on the upper end of mounting plate 6, and then connect support frame 7 and mounting plate 6 stably with screws to achieve stable installation of positioning device 8. Then, personnel align the lower surface of base plate 31 with the ground, and then rotate internal thread cylinder 34. Internal thread cylinder 34 rotates and moves downward under the action of fixing screw 33. Under the limiting action of vertical gripping ribs 37 and oblique gripping ribs 38, adjusting plate 32 will not rotate with internal thread cylinder 34. At the same time, the downward movement of internal thread cylinder 34 drives adjusting plate 32 to move downward, and the downward movement of adjusting plate 32 drives the three vertical gripping ribs 37 to move downward. The three vertical gripping ribs 37 slide downward inside the corresponding vertical sliding mouth, and the lower ends of the three vertical gripping ribs 37 are inserted. At the same time, the adjusting disc 32 moves downward, pushing the three oblique gripping ribs 38 to move. The three oblique gripping ribs 38 slide downward within their corresponding oblique sliding openings, with their lower ends obliquely inserted into the ground. Simultaneously, the downward movement of the three oblique gripping ribs 38 causes adjacent sliding seats 36 to slide within their corresponding sliding grooves 35. The oblique gripping ribs 38 provide diagonal support for the marker pole and increase the vertical constraint between the ground and the marker pole, further improving the marker pole's support stability. Then, the positioning device 8 is activated. The GPS system's space satellites continuously send signals to Earth. These signals contain satellite position information and transmission time. The positioning device 8 receives signals from at least four satellites and measures the signal propagation time. The difference between the signal reception time and the initial transmission time, combined with the speed of light, is used to calculate the distance between the target and each satellite. Then, the positioning device 8 uses its own algorithm and model to correct the errors caused by external interference during signal transmission, thereby obtaining more accurate distance information. The positioning device 8 uses the known coordinates and measured distances of at least 4 satellites, and calculates the three-dimensional coordinates of the target using the principle of three-dimensional resection. The three-dimensional coordinates of the target are then sent to the signal receiving end of the external control and management platform in real time. When the positioning device 8 has completed its work, it rotates the internal threaded cylinder 34 in the opposite direction. The internal threaded cylinder 34 moves upward, causing the adjusting plate 32 to move upward, which in turn causes the vertical gripping rib 37 and the oblique gripping rib 38 to move upward, ending the position locking of the target and the ground.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
