Description

Technical Field

[0001] This invention relates to the field of surveying and mapping services, and in particular to a movable marker device for surveying forestry wetlands. Background Technology

[0002] Forestry wetland surveying is a specialized application of professional surveying services in the field of forestry and wetland ecological protection. Its core is to obtain information on the spatial location, quantity, structure, and dynamic changes of wetlands and surrounding forestry resources through surveying technology, providing accurate geospatial data support for wetland ecological protection, forestry resource management, and planning decisions. Its content revolves around "accurate perception, dynamic monitoring, and ecological assessment of wetland and forestry resources," and can be specifically divided into four modules: basic data collection, specialized element surveying, dynamic monitoring, and ecological thematic analysis.

[0003] Movable markers for forestry wetland surveying are tools used in the process of forestry wetland surveying. Existing movable markers for forestry wetland surveying mainly use a combination of physical marking and electronic positioning for marking. The physical markings are the directly visible physical markers. The terrain of forestry wetlands is often complex, not limited to flat land or depressions, but also includes sloping terrain. When setting up movable markers for forestry wetland surveying, considering rainy weather, anti-erosion protection measures need to be set up. A 50-centimeter diameter ring of gravel (5 to 10 centimeters in diameter) is laid around the base, which is relatively troublesome and affects the setting efficiency.

[0004] Therefore, it is necessary to propose a movable marker device for forestry wetland surveying to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a movable marker device for surveying forestry wetlands, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A movable marker device for surveying forestry wetlands includes a fan-shaped plate, multiple circular holes on the surface of the fan-shaped plate, rectangular grooves on the walls of the circular holes, and a storage groove at the bottom of the fan-shaped plate. A support column is slidably connected to the wall of each circular hole, and a first spring is sleeved on the outer side of each support column. A conical column is rotatably connected to the wall of the storage groove. An arc-shaped baffle is fixedly connected to the edge of the lower surface of the fan-shaped plate. A first enclosure plate is symmetrically fixedly connected to the side of the fan-shaped plate. A second enclosure plate is rotatably connected to the inner side of the first enclosure plate. A first baffle plate capable of contacting a slope surface is installed on the inner side of the second enclosure plate via a torsion spring. Installation grooves are symmetrically formed near the edge of the upper surface of the fan-shaped plate. A transmission gear is rotatably connected to the wall of the installation groove. A circular block is fixedly connected to the surface of the transmission gear. The second enclosure plate is fixedly connected to the circular block. One of the support columns is meshed with both transmission gears. Limiting mechanisms for limiting the movement of the support column are provided on the walls of the multiple rectangular grooves. The limiting mechanism includes a movable column slidably connected to the wall of a rectangular groove. A second spring is sleeved on the outer side of the movable column. A positioning block is fixedly connected to one end of the movable column near the support column. A first trapezoidal block is fixedly connected to the other end of the movable column. A through hole is opened at the center of the upper surface of the sector plate. A fixed sleeve is fixedly connected to the surface of the through hole. A strip groove is symmetrically opened on the outer side of the fixed sleeve. A limiting groove is opened in the wall of the strip groove. A movable sleeve is sleeved on the outer side of the fixed sleeve. A limiting rod is slidably connected to the wall of the strip groove. Both limiting rods are slidably connected to the movable sleeve. An indicator rod is rotatably connected to the end of the movable sleeve away from the fixed sleeve.

[0007] Preferably, the surface of the conical column is provided with grooves evenly distributed in a ring at equal intervals, and the groove walls are fitted with arc-shaped plates by torsion springs. The end face of the conical column near the fixed sleeve is provided with a column groove, and multiple grooves are connected to the column groove. An adjusting column is slidably connected to the groove wall, and multiple arc-shaped plates are installed in cooperation with the adjusting column.

[0008] Preferably, a cylinder is fixedly connected to the inner wall of the movable sleeve, and the cylinder is slidably connected to the inner wall of the fixed sleeve. A second trapezoidal block, which is evenly distributed in a ring, is fixedly connected to one end of the movable sleeve near the sector plate.

[0009] Preferably, a third spring is sleeved on the outer side of the limiting rod, one end of the third spring is fixedly connected to the limiting rod, and the other ends of both third springs are fixedly connected to the outer side of the movable sleeve. A fixing ring is fixedly connected to the surface of the movable sleeve above the two limiting rods. A fourth spring is sleeved on the outer side of the movable sleeve, the lower end of the fourth spring is fixedly connected to the fixing ring, and an annular block is fixedly connected to the upper end of the fourth spring. A first limiting block, evenly distributed in a ring, is fixedly connected to the end face of the annular block away from the fourth spring. A rotating block is fixedly connected to the end face of the movable sleeve away from the sector plate. A second limiting block, evenly distributed in a ring, is fixedly connected to the outer side of the rotating block. The first limiting block and the second limiting block are fitted together. A mounting base is fixedly connected to the surface of the rotating block away from the movable sleeve. The marking rod is rotatably connected to the mounting base. Limiting gears are symmetrically fixedly connected to the end of the marking rod near the rotating block. The first limiting block and the limiting gears are fitted together.

[0010] Preferably, the fourth spring is initially in a compressed state, and the third spring is initially in a stretched state.

[0011] Preferably, a friction ring is fitted inside the annular block, and the friction ring is fixedly connected to the movable sleeve.

[0012] Preferably, a support block is rotatably connected to the lower end of the support column.

[0013] Compared with the prior art, the present invention provides a movable marker device for surveying forestry wetlands, which has the following beneficial effects: This movable marker device for forestry wetland surveying, through the setting of an arc-shaped baffle, a first baffle, a first enclosure, and a second enclosure, with the first baffle in contact with the slope surface and the two first baffles cooperating with the arc-shaped baffle, allows water to be diverted by the arc-shaped baffle and the two first baffles as it flows on the slope surface, thus protecting the entire structure and preventing deviations in the setting of the movable marker device due to rainwater erosion. This ensures the surveying effect and eliminates the need to lay gravel to form a ring-shaped protective circle, thereby optimizing the operation steps and improving the setting efficiency of the movable marker device.

[0014] This movable marker device for forestry wetland surveying works by adjusting the rotation of a conical column to make it perpendicular to the fan-shaped plate. The conical column is then vertically inserted into the forestry wetland. During this process, the support block below the support column also contacts the slope surface. The first spring is compressed, causing relative sliding between the support column and the circular hole. The transmission gear is adjusted and rotated, thus driving the circular block to rotate. The second enclosure plate rotates relative to the first enclosure plate, and the first baffle is also adjusted to contact the slope surface. The cylinder is inserted into the fixed sleeve and then contacts the adjusting column, causing the adjusting column to move. Multiple arc-shaped plates are adjusted and rotated, forming a barb-like structure to ensure overall stability. During this process, the limiting rod, under the elastic force of the third spring, can insert into the limiting groove. The first limiting block cooperates with the second limiting block, and the first limiting block also cooperates with the limiting gear to complete the rotation adjustment of the marker rod. In other words, while the conical column is inserted into the slope, the angles of the first baffle and second enclosure plate, the arc-shaped plate, and the marker rod are simultaneously adjusted, thereby further improving the setting efficiency of the movable marker device.

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

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 A movable marker device for surveying forestry wetlands includes a sector-shaped plate 1, multiple circular holes 11 on the surface of the sector-shaped plate 1, rectangular grooves 12 on the walls of the circular holes 11, and a receiving groove 17 at the bottom of the sector-shaped plate 1. Support columns 13 are slidably connected to the walls of the circular holes 11, and a first spring 14 is sleeved on the outer side of the support columns 13. A conical column 15 is rotatably connected to the wall of the receiving groove 17. An arc-shaped baffle 16 is fixedly connected to the lower edge of the sector-shaped plate 1, and first surrounding plates 2 are symmetrically fixedly connected to the sides of the sector-shaped plate 1. A second enclosure 3 is rotatably connected to the inner side of enclosure 2. A first baffle 4 that can contact the slope surface is installed on the inner side of the second enclosure 3 by a torsion spring. A mounting groove 5 is symmetrically opened on the upper surface of the fan-shaped plate 1 near the edge. A transmission gear 6 is rotatably connected to the groove wall of the mounting groove 5. A circular block 7 is fixedly connected to the surface of the transmission gear 6. The second enclosure 3 is fixedly connected to the circular block 7. One of the support columns 13 is meshed with both transmission gears 6. The groove walls of multiple rectangular grooves 12 are provided with a limiting mechanism 8 to limit the support column 13. The limiting mechanism 8 includes a movable column 81 slidably connected to the wall of the rectangular groove 12. A second spring 82 is sleeved on the outside of the movable column 81. A positioning block 83 is fixedly connected to one end of the movable column 81 near the support column 13. A first trapezoidal block 84 is fixedly connected to the other end of the movable column 81. A through hole 85 is opened at the center of the upper surface of the sector plate 1. A fixed sleeve 86 is fixedly connected to the surface of the through hole 85. A strip groove 87 is symmetrically opened on the outside of the fixed sleeve 86. A limiting groove 88 is opened on the wall of the strip groove 87. A movable sleeve 89 is sleeved on the outside of the fixed sleeve 86. A limiting rod 810 is slidably connected to the wall of the strip groove 87. Both limiting rods 810 are slidably connected to the movable sleeve 89. An indicator rod 811 is rotatably connected to the end of the movable sleeve 89 away from the fixed sleeve 86.

[0019] Please see Figure 9 and Figure 10 The tapered column 15 has grooves 151 evenly distributed in a ring at equal intervals on its surface. The groove walls of the grooves 151 are fitted with arc-shaped plates 152 by torsion springs. The tapered column 15 has a column groove 153 on its end face near the fixed sleeve 86. Multiple grooves 151 are connected to the column groove 153. The groove walls of the column groove 153 are slidably connected to an adjusting column 154. Multiple arc-shaped plates 152 are fitted with the adjusting column 154. It should be noted that after the conical column 15 is inserted into the slope, the cylindrical column 891 moves to contact the adjusting column 154, and the adjusting column 154 moves. The adjusting column 154 and the arc plate 152 move relative to each other, and the arc plate 152 is adjusted and rotated. The arc plate 152 is embedded in the soil around the conical column 15, forming a barb-like structure, which can ensure the stability of the conical column 15 after it is inserted into the slope.

[0020] Please see Figure 6 A cylinder 891 is fixedly connected to the inner wall of the movable sleeve 89. The cylinder 891 is slidably connected to the inner wall of the fixed sleeve 86. A second trapezoidal block 892, which is evenly distributed in a ring, is fixedly connected to one end of the movable sleeve 89 near the sector plate 1. It should be noted that during the process of adjusting the cylinder 891 to be inserted into the fixed sleeve 86, the movable sleeve 89 moves together with the cylinder 891, the second trapezoidal block 892 contacts the first trapezoidal block 84 and moves relative to it, so that the positioning block 83 can make close contact with the surface of the support column 13. By using the friction between the two, the support column 13 is positioned and limited after adjustment, ensuring that the whole is placed stably on the slope surface.

[0021] Please see Figure 4 and Figure 5A third spring 8101 is sleeved on the outer side of the limiting rod 810. One end of the third spring 8101 is fixedly connected to the limiting rod 810, and the other ends of both third springs 8101 are fixedly connected to the outer side of the movable sleeve 89. A fixing ring 8910 is fixedly connected to the surface of the movable sleeve 89 above the two limiting rods 810. A fourth spring 8911 is sleeved on the outer side of the movable sleeve 89. The lower end of the fourth spring 8911 is fixedly connected to the fixing ring 8910, and an annular block 893 is fixedly connected to the upper end of the fourth spring 8911. The annular block 893 is fixedly connected to the end face away from the fourth spring 8911. There are first limiting blocks 894 evenly distributed in a ring. A rotating block 895 is fixedly connected to the end face of the movable sleeve 89 away from the sector plate 1. A second limiting block 896 evenly distributed in a ring is fixedly connected to the outer side of the rotating block 895. The first limiting block 894 and the second limiting block 896 are installed together. A mounting base 897 is fixedly connected to the surface of the rotating block 895 away from the movable sleeve 89. The marking rod 811 is rotatably connected to the mounting base 897. A limiting gear 898 is symmetrically fixedly connected to one end of the marking rod 811 near the rotating block 895. The first limiting block 894 and the limiting gear 898 are installed together. It should be noted that during the installation of the fixed sleeve 86 and the movable sleeve 89, the cylinder 891 is inserted into the fixed sleeve 86. The operator holds the surface of the annular block 893 with one hand and adjusts the angle of the marker rod 811 with the other. Since the rotating block 895 is rotatably connected to the movable sleeve 89, and the marker rod 811 is rotatably connected to the mounting base 897, the angle of the marker rod 811 is adjusted according to the actual installation requirements. During this process, relative movement occurs between the annular block 893 and the movable sleeve 89. Utilizing the friction between the annular block 893 and the friction ring 899, the annular block 893 does not immediately return to its original position. Upon reaching the initial position, sufficient time is given for the marker rod 811 to adjust its angle. During this process, the cylinder 891 will contact the adjusting column 154, causing the adjusting column 154 to move, thereby rotating and adjusting the arc plate 152. The limiting rod 810 and the strip groove 87 will move relative to each other until the limiting rod 810 and the limiting groove 88 slide into each other, completing the installation limit of the movable sleeve 89. At the same time, the limit of the marker rod 811 after angle adjustment can also be completed. The first trapezoidal block 84 and the second trapezoidal block 892 can also make close contact during this process, completing the limit of the support column 13 after position adjustment, which can improve the overall setting efficiency. It should be noted that after the overall installation is completed, the two first baffles 4 cooperate with the arc-shaped baffle 16. During the flow of water on the slope surface, the water can be diverted by the arc-shaped baffle 16 and the two first baffles 4, thereby protecting the whole structure and preventing the setting of the movable marker device from being deviated due to rainwater erosion. This ensures the mapping effect, eliminates the need to lay gravel to form a ring-shaped protective ring, optimizes the operation steps, further improves the setting efficiency of the movable marker device, and shortens the time required for mapping services.

[0022] The initial state of the fourth spring 8911 is compressed, and the initial state of the third spring 8101 is stretched. It should be noted that the reaction force generated by the compression of the fourth spring 8911 acts on the surface of the annular block 893. After the first limiting block 894 and the second limiting block 896 are engaged, and the first limiting block 894 is engaged with the limiting gear 898, the fourth spring 8911 is still in a compressed state, ensuring that there is enough force to ensure the stability of the marker rod 811 after angle adjustment. The reaction force generated by the stretching of the third spring 8101 acts on the surface of the limiting rod 810, so that the limiting rod 810 can always be in contact with the groove wall of the strip groove 87 during the relative movement between the limiting rod 810 and the strip groove 87, which facilitates the sliding insertion between the limiting rod 810 and the limiting groove 88, thereby limiting the installation of the movable sleeve 89.

[0023] Please see Figure 6 A friction ring 899 is fitted inside the annular block 893, and the friction ring 899 is fixedly connected to the movable sleeve 89. It should be noted that when the annular block 893 is held by hand and the cylinder 891 is inserted into the fixed sleeve 86, relative movement occurs between the annular block 893 and the movable sleeve 89, and relative movement also occurs between the annular block 893 and the friction ring 899. Utilizing the frictional force between the friction ring 899 and the movable sleeve 89, the annular block 893 will not immediately return to its initial state under the elastic force of the fourth spring 8911. During the resetting process of the annular block 893, that is, before the first limit block 894 and the second limit block 896 come into contact, the angle of the indicator rod 811 is adjusted by rotating the rotating block 895 and rotating the indicator rod 811 according to the actual use needs, and then the annular block 893 returns to its initial state.

[0024] Please see Figure 1 and Figure 3 A support block is rotatably connected to the lower end of the support column 13; It should be noted that the support block can be adjusted and rotated to adapt to the overall setting on the surface of the slope.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
