Description

Technical Field

[0001] The present invention relates to the technical field, and specifically to a topographic surveying device for territorial spatial planning. Background Art

[0002] Territorial spatial planning refers to the long-term planning and overall arrangement of the territorial spatial resources and layout within a country or a specific region, based on natural geographical conditions, economic and social development needs, and ecological environment protection requirements, aiming to achieve effective control and scientific governance of the territorial space and promote the balance between development and protection. To achieve this goal, accurate land measurement is the basis, including the measurement of the area of irregular pits. The existing detection methods mainly rely on laser ranging technology. However, since laser measurement has high requirements for environmental conditions, such as the need for a highly reflective target surface and is easily affected by factors such as environmental light and dust, it is often difficult to accurately judge the area of irregular pits in practical applications.

[0003] Therefore, there is an invention patent with an application number of 202311013985.7 and a patent name of a land area measuring device, which includes a land measuring instrument, and a wire winding roller is detachably installed inside the land measuring instrument. First, a plurality of shrinkage snap columns and movable columns are installed together and fixed at the edge of the land to be measured through fixed cones, which can adapt to land measurements of different shapes. No matter how many turns there are at the land edge, the same number of devices can be used in combination. However, when measuring the area of pits with irregular edges in the above solution, multiple measuring instruments are required for measurement, resulting in high costs, complex operations, and the adjacent measuring instruments are straight lines, affecting the measurement accuracy.

[0027] As Figure 1 shown, a topographic surveying device for territorial space planning includes a column 1, a swing arm provided on the column 1 and rotatable on the column 1, a fixing mechanism provided at the upper end of the column 1 for fixing surveying paper, a punching mechanism provided on the swing arm for punching holes in the surveying paper. A support wheel 2 cooperating with the edge of the pit is movably provided on the swing arm. A first sleeve 3 is provided on the swing arm. The first sleeve 3 is connected to the end of the swing arm through a tension spring 4. A support mechanism supported on the ground is provided at the end of the swing arm. During surveying, the column 1 is supported at the bottom of the pit, the support wheel 2 is supported at the edge position of the pit. Under the action of the tension spring 4, the support wheel 2 is always in contact with the edge of the pit. The swing arm swings. At the same time, the punching mechanism moves on the swing arm along with the first sleeve 3 and punches holes in the surveying paper. The punching trajectory corresponds to the shape of the pit, thus realizing accurate proportional surveying of the pit. It has low cost, high surveying efficiency, and high surveying accuracy. Compared with the laser surveying method, it has less environmental requirements.

[0028] As Figure 1As shown, the swing arm includes a support sleeve 11 and a telescopic rod 12 with its inner end extending into the support sleeve 11 and moving within the support sleeve 11. The telescopic movement of the telescopic rod 12 can adapt to pit holes of different sizes.

[0029] As Figure 4 and Figure 5 As shown, the punching mechanism includes a second sleeve 5 arranged on the swing arm and moving on the swing arm, a chute 6 arranged in parallel at the lower end of the second sleeve 5, a first moving block 7 arranged in the chute 6 at the left end and moving up and down in the chute 6 at the left end, a second moving block 8 arranged in the chute 6 at the right end and moving up and down in the chute 6 at the right end. A punching needle 9 is provided at the upper end of the first moving block 7. When the second moving block 8 moves up and down, the first moving block 7 moves up and down under the action of the connecting mechanism. The first sleeve 3 and the second sleeve 5 are connected by a connecting rod 10. When the second moving block 8 moves up and down, under the action of the connecting mechanism, the first moving block 7 continuously moves up and down, and the punching needle 9 punches holes in the mapping paper. By setting the connecting rod, the synchronous movement of the first sleeve 3 and the second sleeve 5 is realized, so as to realize proportional mapping.

[0030] As Figure 2 and Figure 5 As shown, a long hole 13 is provided on the support sleeve 11. The punching needle 9 passes through the long hole 13 to punch holes in the mapping paper. By setting the long hole, the second sleeve 5 will not be locked when moving.

[0031] As Figure 4 As shown, a baffle 14 is provided at the lower end of the chute 6 at the left end to prevent the first moving block 7 from falling out of the chute.

[0032] As Figure 4 and Figure 6As shown in the figure, the connecting mechanism includes a slide rod 15 disposed within and movable within the first moving block 7, a positioning head 16 disposed at the end of the slide rod 15, and a limiting head 17 disposed at the middle position between the two chutes 6.

When the second moving block 8 moves upward, under the action of the positioning rod 20 and the positioning head 16, the first moving block 7 moves upward, and the punching needle 9 punches holes. When the positioning head 16 contacts the limiting head 17, the slide rod 15 retracts against the elastic force of the first compression spring 18, and the positioning head 16 separates from the positioning rod 20. Under the elastic force of the second compression spring 22, the first moving block 7 descends, and under the action of the first compression spring 18, the positioning block resets. By providing the groove 21, interference between the positioning rod 20 and the limiting head is prevented.

A driving rod 36 is provided on the driving disk 31, and a driving hole 37 cooperating with the driving rod 36 is provided on the side surface of the second moving block 8. The end of the rotating shaft 30 is connected to the rotating shaft of the traveling wheel set 29 through bevel gears. When the traveling wheel set 29 rotates, the rotating shaft 30 rotates under the action of the bevel gears. The rotation of the rotating shaft 30 drives the first belt 34 to move, and the first belt 34 drives the second belt 35 to move, thereby causing the driving disk 31 to rotate accordingly.

[0036] Among them, two coaxially arranged pulleys are fixed on the pin where the first connecting rod 32 is hinged to the second connecting rod 33. One pulley is connected to the rotating shaft of the driving disk 31 through the first belt 34, and the other pulley is connected to the rotating shaft 30 through the second belt 35.
