Description

Technical Field

[0001] This invention relates to the field of geographic surveying equipment technology, and in particular to a portable geographic surveying device. Background Technology

[0002] Geographic surveying and mapping is the process of collecting ground coordinates through technical means to generate topographic maps, geographic information databases, and other related work. It provides basic data support for all industries that require spatial location information and is commonly used in engineering construction, land resources, and other related fields.

[0003] The prism bracket, GNSS receiver module bracket, and total station tripod are three completely independent sets of equipment. When working in the field, it is necessary to carry three sets of brackets and accessories at the same time. The equipment is heavy, which puts a great burden on the personnel to carry. Moreover, each time the measurement mode is switched, the original equipment must be disassembled and a new bracket must be re-erected. The waiting time for the bracket to be erected is long, which affects the measurement progress. Small surveying drones have become standard equipment for field measurement. The operators need to carry a special drone storage box, forming a multi-box carrying mode, which further increases the carrying burden. Summary of the Invention

[0004] This invention provides a portable geographic surveying and mapping device. Through the switching of the upper function conversion frame, it enables switching between measurement modes such as prism module, GNSS receiver module, and total station support. This integrates three surveying and mapping methods: prism measurement, GNSS satellite positioning, and total station setup. It eliminates the need to carry three separate sets of equipment: prism support, GNSS receiver module support, and total station tripod. The number of measurement supports is greatly reduced, decreasing the number of surveying and mapping equipment carried and the burden on personnel. Furthermore, the lower drone storage box can also store the surveying drone, eliminating the need for a separate container for the drone, further reducing the number of equipment required for field operations and lowering the burden on personnel.

[0005] This invention provides a mobile geographic surveying and mapping device, specifically comprising an upper lifting surveying frame, a middle surveying support, lower support legs, and a lower movable frame. The lower part of the upper lifting surveying frame is slidably connected to the middle surveying support. The lower part of the middle surveying support has three sets of lower support legs arranged in a circular interval array. The tail end of each set of lower support legs is rotatably connected to the lower movable frame. The upper end of the upper lifting surveying frame is slidably connected to a middle positioning pin. The upper lifting surveying frame and the upper functional conversion frame are rotatably connected in the middle. The upper functional conversion frame is fixedly connected in an interval array to an upper prism module, a GNSS receiver module, and a total station connection base. The upper functional conversion frame is a three-arm T-shaped turntable structure, with the upper prism module, the GNSS receiver module, and the total station connection base fixedly connected to the three arm ends, respectively.

[0006] Furthermore, the upper function conversion frame is provided with a ring-shaped interval array of pin connection holes. The central positioning pin and the pin connection holes are slidably connected. The pin connection holes are set one-to-one with the upper prism module, GNSS receiver module, and total station connection base, so as to realize the circumferential positioning work of rotating the upper function conversion frame to switch the upper prism module, GNSS receiver module, and total station connection base, without the need to carry three separate sets of equipment: prism bracket, GNSS receiver module bracket, and total station tripod.

[0007] Furthermore, the upper end of the middle surveying bracket is threadedly connected with an upper tightening positioning screw, and the upper end of the middle surveying bracket is rotatably connected with a side fixing clip, which is used to fix the control terminal of the handheld device or GNSS receiver module. The lower end of the middle surveying bracket is fixedly connected to the upper cover plate, and the upper cover plate and the middle coil spring of the upper positioning clip are rotatably connected. The upper cover plate and the lower UAV storage box are hinged, and the lower UAV storage box is used to store small surveying UAVs.

[0008] Furthermore, the tail end of the upper tightening positioning screw abuts against the upper lifting surveying frame, and the upper positioning clip engages with the lower drone storage box. Under the action of the spring force, the upper positioning clip engages with the side wall of the lower drone storage box, thereby locking the lower drone storage box after it is closed. The lower drone storage box can store a small surveying drone, eliminating the need to carry a separate drone storage box. The lower drone storage box contains a sponge with a groove that fits the shape of the small surveying drone for positioning and cushioning.

[0009] Furthermore, a middle support rod is rotatably connected to the middle of the lower support leg, the upper end of the lower support leg is rotatably connected to the upper connecting frame, a lower tightening positioning screw is threadedly connected to the middle of the upper connecting frame, and a lower connecting slide is axially slidably connected to the lower part of the upper connecting frame.

[0010] Furthermore, the lower clamping positioning screw abuts against the lower connecting slide to lock the position of the lower connecting slide. The outer side of the lower connecting slide is provided with a rotating central support rod in a circular array, and the lower support leg is provided in a circular array on the outside of the upper connecting frame.

[0011] Furthermore, the side of the lower moving frame and the outer connecting frame are rotatably connected. The lower moving frame has an equilateral triangle structure. Three sets of rotating inner rollers are arranged in a circular array on the lower moving frame. The inner rollers are arranged in a triangular array. The outer sides of the three sets of inner rollers are supported by a circular anti-slip outer belt, forming a tracked walking structure. The circular anti-slip outer belt has an equilateral triangle structure.

[0012] Furthermore, the tail end of the outer connecting frame and the lower end of the lower support leg are rotatably connected, the middle support rod is fixedly connected to the bottom of the lower UAV storage box, and the lower end of the middle support rod is rotatably connected to the outer side wall of the lower connecting slide. The middle support rod and the lower support leg cooperate to form a triangular stable support structure.

[0013] This invention provides a mobile geographic surveying and mapping device, which has the following advantages: The upper function conversion frame allows for switching between measurement modes such as prism module, GNSS receiver module, and total station support. It integrates three types of surveying and mapping support for prism measurement, GNSS satellite positioning, and total station setup, eliminating the need to carry three separate sets of equipment: prism support, GNSS receiver module support, and total station tripod. This significantly reduces the number of measurement supports, lowers the burden on personnel carrying and transporting surveying and mapping equipment, reduces equipment installation time, and improves measurement efficiency.

[0014] The storage container for unmanned aerial vehicles (UAVs) can also store surveying UAVs, eliminating the need for separate containers for surveying UAVs. This further reduces the number of devices, lowers the burden of carrying them while walking outdoors, and reduces the number of devices required for field operations, avoiding the hassle of transporting multiple containers.

[0015] The lower support leg extends to serve as the support structure for the central surveying scaffold. When the lower support leg closes, the annular anti-slip outer belt of the lower moving frame contacts the ground, forming a tracked walking mechanism. The rotation of the annular anti-slip outer belt assists the central surveying scaffold in moving along the ground, reducing the pushing resistance of personnel, eliminating the need for personnel to carry the scaffold on their shoulders or backs, and reducing the physical burden of movement.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to... Figures 1 to 8 : This invention proposes a mobile geographic surveying and mapping device, comprising an upper lifting surveying frame 1, a middle surveying support 2, lower support legs 3, and a lower movable frame 4. The upper lifting surveying frame 1 has a central positioning pin 101 slidably connected to its upper end. The upper lifting surveying frame 1 has a displacement cylindrical rod structure. The upper lifting surveying frame 1 and the upper functional conversion frame 102 are rotatably connected at their middle sections. The upper functional conversion frame 102 has an upper prism module 103, a GNSS receiver module 104, and a total station connection base 105 fixedly connected in an array at intervals. The upper functional conversion frame 102 is a three-arm T-shaped turntable structure, with the upper prism module 103, GNSS receiver module 104, and total station connection base 105 fixedly connected to its three arms respectively. The upper lifting surveying frame 1 moves axially along the middle surveying support 2, thereby adjusting its height and allowing it to rise. The lower part of the lower surveying frame 1 is slidably connected to the middle surveying support 2, which is a cylindrical tubular structure. The upper end of the middle surveying support 2 is threadedly connected to the upper tightening positioning screw 201. The upper end of the middle surveying support 2 is rotatably connected to the side fixing clip 202, which is used to fix the control terminal of the handheld device or GNSS receiver module 104. The lower end of the middle surveying support 2 is fixedly connected to the upper cover plate 203. The upper cover plate 203 and the upper positioning clip 204 are rotatably connected with the coil spring in the middle. The upper cover plate 203 is hinged to the lower UAV storage box 205. The lower UAV storage box 205 is used to store small surveying UAVs. The lower UAV storage box 205 is equipped with a sponge with a groove that fits the shape of the small surveying UAV. The sponge provides positioning and cushioning for the small surveying UAV to avoid collisions. The lower part of the surveying support 2 is arranged in a ring-shaped array with three sets of lower support legs 3. A middle support rod 301 is rotatably connected to the middle of each lower support leg 3. The upper end of each lower support leg 3 is rotatably connected to an upper connecting frame 302. A lower tightening positioning screw 303 is threadedly connected to the middle of the upper connecting frame 302. A lower connecting slide 304 is axially slidably connected to the lower part of the upper connecting frame 302. The lower tightening positioning screw 303 and the lower connecting slide 304 abut against each other to lock the position of the lower connecting slide 304. A rotating middle support rod 301 is arranged in a ring-shaped array on the outer side of the lower connecting slide 304. The middle support rod 301 and the lower support legs 3 cooperate to form a triangular stable support structure. The lower support legs 3 are arranged in a circular array on the outside of the upper connecting frame 302. Each lower support leg 3 has a lower moving frame 4 rotatably mounted at its tail end. The lower moving frame 4 is an equilateral triangle structure. The side of the lower moving frame 4 is rotatably connected to the outer connecting frame 401. The lower moving frame 4 has three sets of rotating inner rollers 402 arranged in a triangular array. The three sets of inner rollers 402 are supported and rotated by a ring-shaped anti-slip outer belt 403 on their outer sides. The ring-shaped anti-slip outer belt 403 is an equilateral triangle structure. The ring-shaped anti-slip outer belt 403 forms a tracked walking structure, which is suitable for moving on complex terrains such as mud and slopes. The resistance of movement pushed by personnel is greatly reduced, reducing the physical burden of personnel for long-distance transfer.

[0022] The upper function conversion frame 102 is equipped with a ring-shaped interval array of pin connection holes 106. The central positioning pin 101 is slidably connected to the pin connection holes 106. The pin connection holes 106 are set one-to-one with the upper prism module 103, GNSS receiver module 104, and total station connection base 105, so as to realize the circumferential positioning work of the upper function conversion frame 102 rotating and switching the upper prism module 103, GNSS receiver module 104, and total station connection base 105. It eliminates the need to carry three separate sets of equipment: prism support, GNSS receiver module 104 support, and total station tripod. This further reduces the number of surveying supports that need to be carried in the field and greatly reduces the equipment handling pressure on personnel.

[0023] In this embodiment, the tail end of the upper tightening positioning screw 201 abuts against the upper lifting surveying frame 1, and the upper positioning clip 204 engages with the lower drone storage box 205. Under the action of the spring force, the upper positioning clip 204 engages with the side wall of the lower drone storage box 205, thereby locking the lower drone storage box 205 after it is closed. The lower drone storage box 205 can store a small surveying drone, eliminating the need to carry a separate drone storage box, reducing the number of equipment required for field operations, and achieving integrated carrying of the surveying bracket and the drone.

[0024] In this embodiment, the tail end of the outer connecting frame 401 and the lower end of the lower support leg 3 are rotatably connected, the middle support rod 301 is fixedly connected to the bottom of the lower UAV storage box 205, and the lower end of the middle support rod 301 is rotatably connected to the outer side wall of the lower connecting slide 304. The middle support rod 301 and the lower support leg 3 cooperate to form a triangular stable support structure to achieve the stability requirements of the measurement.

[0025] In this second embodiment, based on the first embodiment, an angle locking buckle structure consisting of an elastic spring and a positioning groove is provided at the rotatable connection between the outer connecting frame 401 and the lower support leg 3. When the lower moving frame 4 rotates to the walking angle, the elastic spring automatically engages in the positioning groove, locking the three sets of annular anti-slip outer belts 403 of the lower moving frame 4. This ensures that the lower moving frame 4 and the annular anti-slip outer belt 403 of the adjacent lower support leg 3 remain in a parallel state. This prevents the rotation between the outer connecting frame 401 and the lower support leg 3 during movement from causing the angle between the lower moving frame 4 and the annular anti-slip outer belt 403 of the adjacent lower support leg 3 to change the parallel state. It also prevents the free rotation of the middle and outer connecting frame 401 from causing the walking direction to deviate, ensuring the stability of the device's movement.

[0026] The working principle of this invention is as follows: the lower tightening positioning screw 303 is unscrewed and rotated, and the lower tightening positioning screw 303 moves away from the lower connecting slide 304 along the thread axis, the axial positioning of the lower connecting slide 304 is released, the lower connecting slide 304 moves upward, and the lower connecting slide 304 simultaneously drives the middle support rod 301 to move. The middle support rod 301 pushes the lower support leg 3 to unfold outward, and then the lower tightening positioning screw 303 moves along the thread axis to tighten the lower connecting slide 304, the position of the lower connecting slide 304 is fixed, and the middle support rod 301 and the lower support leg 3 cooperate to form a triangular stable support structure, which meets the stability requirements of measurement. By moving the upper tightening positioning screw 201 away from the sliding connecting column at the bottom of the upper lifting surveying frame 1 along the threaded axis, the upper lifting surveying frame 1 moves along the axis of the middle surveying support 2, thereby adjusting the height of the upper lifting surveying frame 1. The upper tightening positioning screw 201 moves closer to the upper lifting surveying frame 1 along the threaded axis, achieving axial positioning of the upper lifting surveying frame 1. The middle positioning pin 101 separates from the pin connection hole 106, releasing the limit of the upper function conversion frame 102. Through the rotation of the three-arm T-shaped upper function conversion frame 102, the upper prism module 103, GNSS receiver module 104, and total station connection base 105 are connected. The switching mechanism allows for positioning by sliding the positioning pin 101 and the pin connection socket 106 together, enabling the switching between three commonly used measurement modes: prism measurement, GNSS satellite positioning, and total station setup. This combines the three types of surveying and mapping supports into one, eliminating the need to carry three separate sets of equipment: a prism support, a GNSS receiver module 104 support, and a total station tripod. This significantly reduces the number of measurement supports required for field operations, greatly reducing the burden of equipment handling for personnel. It also avoids time losses during the disassembly and assembly of multiple devices, shortens the setup time for a single device, and improves the efficiency of surveying operations. The upper positioning clip 204 and the lower drone storage box 205 are separated. The lower drone storage box 205, the upper cover plate 203, the middle surveying bracket 2, and the upper lifting surveying frame 1 rotate to one side around the hinge point of the upper cover plate 203 and the lower drone storage box 205. The upper cover plate 203 and the lower drone storage box 205 are separated, and the top of the lower drone storage box 205 is open. The lower drone storage box 205 stores a small surveying drone and accessories such as batteries, propellers, and remote controllers. There is no need to carry a separate drone storage box, which further reduces the number of equipment required for field operations. It realizes the integrated carrying of the surveying bracket and the drone, avoiding the cumbersome handling of multiple boxes. At the same time, it can effectively protect the drone from collisions, dust, and rain corrosion, improving the safety and service life of the equipment. When movement is required, the lower connecting slide 304 moves downward, simultaneously driving the middle support rod 301 to move. The middle support rod 301 pushes the lower support leg 3 to close. The lower moving frame 4 adjusts its direction through the rotating connection between the outer connecting frame 401 and the lower support leg 3, so that the lower moving frame 4 of adjacent lower support legs 3 and the annular anti-slip outer belt 403 are in a parallel state. The annular anti-slip outer belts 403 of both sets of lower moving frames 4 simultaneously contact the ground, forming a tracked walking mechanism. The personnel hold the upper lifting surveying frame 1, keeping the middle surveying support 2 and the lower support leg 3 tilted, and keeping the annular anti-slip outer belt 403 in contact with the ground. The triangular structure of the annular anti-slip outer belt... When encountering large obstacles, the 403 can cross them by synchronously rotating the lower moving frame 4. Personnel hold the upper lifting surveying frame 1 and pull the tilted middle surveying support 2 and lower support leg 3 to move it. The lower support leg 3 works in conjunction with the annular anti-slip outer belt 403, which moves along the ground without the lower support leg 3 contacting the ground. The annular anti-slip outer belt 403 assists the device to move smoothly on complex terrains such as mud, slopes, and gravel, making movement more convenient. It greatly reduces the resistance of personnel pushing the device, significantly reduces the physical burden of long-distance field transfers, eliminates the need for personnel to carry the support on their shoulders and backs, and reduces the workload of personnel.
