Description

Technical Field

[0001] This invention relates to the field of GIS urban spatial measurement device technology, specifically a GIS-based urban spatial measurement device. Background Technology

[0002] Geographic Information Systems (GIS) is a comprehensive discipline that combines geography, cartography, remote sensing, and computer science. It has been widely applied in various fields and is a computer system used to input, store, query, analyze, and display geographic data. With the development of GIS, it is also referred to as "Geographic Information Science." In recent years, it has also been called Geographic Information Services. GIS is a computer-based tool that can analyze and process spatial information (in short, it maps and analyzes phenomena and events on Earth). GIS technology integrates the unique visualization effects and geographic analysis functions of maps with general database operations (such as querying and statistical analysis).

The housing is fixedly disposed on the outer end face of the built-in recording plate. The drawer is slidably connected inside the housing. The rotating base is fixedly disposed in the upper middle part of the drawer. The folding frame is rotatably connected to the upper end face of the rotating base via a rotating shaft. The pad is fixedly installed on the upper end face of the folding frame, and a set of grooves is formed on the upper surface of the pad. A rotating device is provided on the upper end face of the built-in recording plate. A handle is fixedly connected to one side of the rotating device. The instrument body is fixedly installed on the upper end face of the observation mirror body. This invention is a city planning surveying device that effectively copes with the influence of the external environment on the equipment, facilitates the recording of measurement data, and greatly facilitates people's use.

[0004] Existing equipment is typically secured with tripods during use. However, when encountering loose ground, even slight shaking or collisions can cause it to tip over, damaging the top measuring device and causing significant inconvenience to personnel. Furthermore, the existing equipment with securing mechanisms is generally difficult and time-consuming to operate. Therefore, we propose a GIS-based urban spatial measurement device to address these issues. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a GIS-based urban spatial measurement device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a GIS-based urban spatial measurement device, comprising a fixed disk, a plurality of movable rods hinged to the outer wall of the fixed disk, and a support rod sleeved on the outside of the movable rods, a mounting block rotatably connected to the top of the fixed disk, and a measuring device fixedly connected to the top of the mounting block, a ground gripping mechanism inserted into the opposite side of the support rods, a docking mechanism fixedly connected to the top of the ground gripping mechanism, a groove formed at the axis of the fixed disk, and an auxiliary mechanism movably connected to the bottom of the ground gripping mechanism.

[0007] Furthermore, the gripping mechanism includes a mounting plate, a motor, a first transmission gear, a second transmission gear, an external gear ring, a threaded transmission rod, a fixed top plate, and a gripping drill rod. The output end of the motor is fixedly connected to the shaft of the first transmission gear, and the first transmission gear is movably connected to the outer wall of the external gear ring. The bottom end of the second transmission gear is rotatably connected to the top end of the mounting plate. The bottom end of the threaded transmission rod passes through the shaft of the second transmission gear and extends to the outside of the bottom end of the mounting plate. The top end of the gripping drill rod is rotatably connected to the inside of the fixed top plate, and the threaded transmission rod is threadedly connected to the inside of the second transmission gear.

[0008] With the above technical solution, after the equipment is firmly fixed, the motor can be controlled to rotate. When the motor rotates, it will drive the first transmission gear to rotate synchronously. At this time, the transmission gear will drive the gear ring to rotate. During the rotation of the gear ring, it will drive the second transmission gear to rotate. At the same time, the second transmission gear will drive the threaded transmission rod to rotate synchronously. When the threaded transmission rod rotates, it will gradually descend. At the same time, the threaded transmission rod will pull the fixed top plate to move vertically downward. At this time, the gripping drill rod will also descend. In addition, during the descent, the gripping drill rod will rotate under the action of the internal threads of the mounting plate. At this time, the gripping drill rod will be in a rotating descent state, so that the bottom end of the gripping drill rod will drill into the ground.

[0009] Furthermore, multiple threaded drive rods are provided, and the threaded drive rods are evenly distributed at the bottom end of the fixed top plate. The top end of the threaded drive rod is rotatably connected to the top end of the fixed top plate. The gripping drill rod is movably connected to the opposite side of the threaded drive rod. The outer wall of the gripping drill rod is threaded, and the gripping drill rod is threadedly connected to the mounting plate.

[0010] Through the above technical solution, the threaded transmission rod is driven to rotate by the second transmission gear. At this time, the threaded transmission rod will gradually descend as it rotates, and at the same time, the threaded transmission rod will pull the fixed top plate to move vertically downward. At this time, the gripping drill rod will also descend. In addition, during the descent, the gripping drill rod will rotate under the action of the internal threads of the mounting plate. At this time, the gripping drill rod will be in a state of rotating descent, so that the bottom end of the gripping drill rod will drill into the ground.

[0011] Furthermore, the bottom end of the gripping drill rod is movably connected to the inside of the outer gear ring, and the bottom end of the gripping drill rod extends to the outside of the bottom end of the mounting plate. Both the first transmission gear and the second transmission gear mesh with the outer gear ring. The outer gear ring is rotatably connected to the top of the mounting plate, and the outer gear ring is located on the opposite side of the second transmission gear.

[0012] Through the above technical solution, controlling the motor to rotate will drive the first transmission gear to rotate synchronously. At this time, the transmission gear will drive the gear ring to rotate. During the rotation of the gear ring, it will drive the second transmission gear to rotate. Then, the second transmission gear will drive the top part to move, thereby causing the gripping drill rod to rotate and descend.

[0013] Furthermore, the top of the support rod is provided with a slot, and the outer wall of the mounting plate is engaged with the inside of the slot. The motor is fixedly connected to one side of the bottom end of the mounting plate, and the output end of the motor extends into the inside of the mounting plate and is fixedly connected with the transmission gear.

[0014] Through the above technical solution, while adjusting the docking mechanism, the mounting plate can be inserted into the slot to prevent it from falling off. This also allows the equipment to operate normally. Once the equipment is securely fixed, the motor can be controlled to rotate. When the motor rotates, it will drive the first transmission gear to rotate synchronously. At this time, the transmission gear will drive the gear ring to rotate. During the rotation of the gear ring, it will drive the second transmission gear to rotate. Simultaneously, the second transmission gear will drive the threaded transmission rod to rotate synchronously. As the threaded transmission rod rotates, it will gradually descend, and at the same time, the threaded transmission rod will pull the fixed top plate to move vertically downward.

[0015] Furthermore, the docking mechanism includes an outer tube, a shrink tube, a telescopic rod, and a rotating sleeve. The bottom end of the shrink tube is fixedly connected to the inner bottom end of the outer tube, the rotating sleeve is threadedly connected to the inner top end of the outer tube, and the output end of the telescopic rod is movably connected to the rotating sleeve and the inside of the shrink tube.

[0016] With the above technical solution, when the equipment encounters loose ground, simply remove the gripping drill rod and its equipment. Then, insert the output end of the telescopic rod into the inside of the rotating sleeve and rotate the sleeve. As the sleeve rotates, it will gradually descend under the action of the thread. At this time, the bottom end of the rotating sleeve will gradually squeeze the top end of the shrink tube, thereby causing the shrink tube to shrink. The shrink tube will then clamp and fix the top end of the telescopic rod.

[0017] Furthermore, the top end of the telescopic rod is fixedly connected to the inside of the groove, and the bottom end of the outer sleeve is fixedly connected to the top end of the fixed top plate.

[0018] With the above technical solution, by rotating the rotating sleeve, the rotating sleeve will gradually descend under the action of the thread. At this time, the bottom end of the rotating sleeve will gradually squeeze the top end of the shrink tube, thereby shrinking the shrink tube. At this time, the shrink tube will clamp and fix the top end of the telescopic rod.

[0019] Furthermore, the top end of the shrink tube is trapezoidal, and the bottom end of the rotating sleeve is movably connected to the top end of the shrink tube and fixedly connected. The shrink tube forms a rotating tightening structure through the rotating sleeve.

[0020] With the above technical solution, the rotating sleeve gradually descends under the action of the thread as it rotates. At this time, the bottom end of the rotating sleeve gradually squeezes the top end of the shrink tube, thereby causing the shrink tube to shrink.

[0021] Furthermore, the auxiliary mechanism includes a docking plate, a return spring, a docking rod, a connecting plate, and a fixing rod. Multiple return springs are provided, and one end of the return spring is fixedly connected to the top of the docking plate. One end of the docking rod is fixedly connected to the bottom of the docking plate, and the other end of the docking rod is fixedly connected to the top of the connecting plate. The top of the fixing rod is fixedly connected to the bottom of the connecting plate.

[0022] With the above technical solution, when the threaded drive rod rotates and descends, the bottom end of the threaded drive rod will push the top end of the docking plate. At this time, the docking plate will also drive the connecting plate to gradually descend under the pushing action. At this time, the top rod will also be inserted into the ground under its action, thereby further improving the stability of the equipment. When it is necessary to pull it out, it is only necessary to control the motor to rotate in the opposite direction, and the threaded drive rod will drive the top rod to pull it out of the ground.

[0023] Furthermore, the top end of the docking plate is rotatably connected to the bottom end of the threaded transmission rod, and the other end of the reset spring is fixedly connected to the bottom end of the mounting plate.

[0024] By using the above technical solution, and by setting the bottom end of the docking plate and the threaded transmission rod to be rotatably connected, the equipment can descend synchronously with the threaded transmission rod without affecting its rotation, thus ensuring normal operation.

[0025] Compared with existing technologies, this GIS-based urban spatial measurement device has the following advantages:

[0026] I. This invention, through its ground-gripping mechanism, allows the mounting plate to be inserted into the slot while adjusting the docking mechanism. After the equipment is securely fixed, the motor can be controlled to rotate. The motor's rotation drives the first transmission gear to rotate synchronously, which in turn drives the gear ring to rotate. During the gear ring's rotation, the second transmission gear rotates, simultaneously driving the threaded transmission rod to rotate. As the threaded transmission rod rotates, it gradually descends, pulling the fixed top plate vertically downwards. The ground-gripping drill rod also descends accordingly. Furthermore, during its descent, the drill rod rotates under the action of the internal threads of the mounting plate, resulting in a rotating and descending state. This allows the bottom end of the drill rod to drill into the ground, thus securing the equipment and improving its stability during use. This prevents the equipment from tipping over. Combined with the docking mechanism, the equipment can be effectively fixed and limited when encountering different ground surfaces, preventing damage and economic losses.

[0027] Second, this invention, through its docking mechanism, allows the device to easily access loose ground. Simply remove the gripping drill rod and its components, insert the output end of the telescopic rod into the rotating sleeve, and rotate the sleeve. As the sleeve rotates, it gradually descends due to the screw thread, causing the bottom of the sleeve to gradually press against the top of the contraction tube, thus contracting the tube. The contraction tube then clamps and secures the top of the telescopic rod, preventing the device from loosening or falling during use or relocation. Furthermore, the detachable gripping drill rod facilitates storage and operation, reducing the difficulty of manual work.

[0028] Third, this invention utilizes an auxiliary mechanism. As the threaded drive rod rotates and descends, its bottom end pushes the top end of the docking plate. This push causes the docking plate to gradually descend, and the top rod inserts into the ground, further enhancing the equipment's stability. When it needs to be pulled out, simply reverse the motor's rotation to pull the top rod out of the ground via the threaded drive rod. This effectively reduces the difficulty of operation and minimizes wasted time. Furthermore, the auxiliary mechanism prevents the gripping drill rod from loosening and detaching from the ground during use, improving equipment safety.

[0029] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from an examination of the following, or may be learned from the practice of the invention.

Detailed Implementation

[0041] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1-10As shown, the present invention provides a technical solution: a GIS-based urban spatial measurement device, including a fixed plate 1, a plurality of movable rods 2 hinged to the outer wall of the fixed plate 1, and a support rod 3 sleeved on the outside of the movable rods 2, an installation block 4 rotatably connected to the top of the fixed plate 1, and a measuring device 5 fixedly connected to the top of the installation block 4, a ground gripping mechanism 7 inserted into the opposite side of the support rod 3, a docking mechanism 8 fixedly connected to the top of the ground gripping mechanism 7, a groove 6 opened at the axis of the fixed plate 1, and an auxiliary mechanism 9 movably connected to the bottom end of the ground gripping mechanism 7.

[0043] In use, after the equipment is moved to the required location, the support rod 3 can be manually unfolded. The height of the equipment can then be adjusted using the support rod 3 and the movable rod 2 for spatial measurement. When the equipment encounters loose ground, simply remove the gripping drill rod 708 and the equipment itself. Then, insert the output end of the telescopic rod 803 into the rotating sleeve 804 and rotate the sleeve 804. As the sleeve rotates, it gradually descends due to the threaded action. The bottom end of the sleeve 804 gradually presses against the top end of the contraction tube 802, causing the contraction tube 802 to contract. The contraction tube 802 then clamps and secures the top end of the telescopic rod 803, preventing damage during use or relocation. During the process, some parts may loosen and fall off. Making the gripping drill rod 708 detachable makes it easier for personnel to store the equipment. Furthermore, this device makes operation easier, reducing the difficulty of work. While adjusting the docking mechanism 8, the mounting plate 701 can be inserted into the slot. After securing the equipment, the motor 702 can be controlled to rotate. When the motor 702 rotates, it drives the first transmission gear 703 to rotate synchronously. This transmission gear then drives the gear ring to rotate, which in turn drives the second transmission gear 704 to rotate. Simultaneously, the second transmission gear 704 drives the threaded transmission rod 706 to rotate. As the threaded drive rod 706 rotates, it gradually descends. Simultaneously, the threaded drive rod 706 pulls the fixed top plate 707 vertically downwards, causing the gripping drill rod 708 to descend as well. Furthermore, during its descent, the gripping drill rod 708 rotates under the action of the internal threads of the mounting plate 701, resulting in a rotating and descending state. This allows the bottom end of the gripping drill rod 708 to drill into the ground, thus securing the equipment and improving its stability during use. This prevents the equipment from tipping over. Furthermore, in conjunction with the docking mechanism 8, it ensures effective fixation and limitation of the equipment when encountering different ground surfaces, preventing equipment damage and economic losses. Furthermore, during the rotation and descent of the threaded drive rod 706, the bottom end of the threaded drive rod 706 pushes the top end of the docking plate 901. At this time, the docking plate 901 also drives the connecting plate 904 to gradually descend under the pushing action. At this time, the top rod will also insert into the ground under its action, thereby further improving the stability of the equipment. When it is necessary to pull it out, simply control the motor 702 to rotate in the opposite direction, and the threaded drive rod 706 will drive the top rod to pull it out of the ground, thereby effectively reducing the difficulty of operation and reducing the waste of personnel time. In addition, the auxiliary mechanism 9 can prevent the gripping drill rod 708 from loosening and detaching from the ground during use, improving the safety of the equipment.

[0044] like Figures 2-5As shown, the gripping mechanism 7 includes a mounting plate 701, a motor 702, a first transmission gear 703, a second transmission gear 704, an external gear ring 705, a threaded transmission rod 706, a fixed top plate 707, and a gripping drill rod 708. The output end of the motor 702 is fixedly connected to the shaft of the first transmission gear 703, and the first transmission gear 703 is movably connected to the outer wall of the external gear ring 705. The bottom end of the second transmission gear 704 is rotatably connected to the top end of the mounting plate 701. The bottom end of the threaded transmission rod 706 passes through the shaft of the second transmission gear 704 and extends to the outside of the bottom end of the mounting plate 701. The top end of the gripping drill rod 708 is rotatably connected to the inside of the fixed top plate 707. The threaded transmission rod 706 is threadedly connected to the inside of the second transmission gear 704. Multiple threaded transmission rods 706 are provided and are evenly distributed at the bottom end of the fixed top plate 707. The top end of the threaded transmission rod 706... The top end of the support rod 708 is rotatably connected to the top of the fixed top plate 707. The gripping drill rod 708 is movably connected to the opposite side of the threaded transmission rod 706. The outer wall of the gripping drill rod 708 is threaded, and the gripping drill rod 708 is threadedly connected to the mounting plate 701. The bottom end of the gripping drill rod 708 is movably connected to the inside of the outer gear ring 705, and the bottom end of the gripping drill rod 708 extends to the outside of the bottom end of the mounting plate 701. The first transmission gear 703 and the second transmission gear 704 are both meshed with the outer gear ring 705. The outer gear ring 705 is rotatably connected to the top of the mounting plate 701, and the outer gear ring 705 is located on the opposite side of the second transmission gear 704. The top end of the support rod 3 is provided with a slot, and the outer wall of the mounting plate 701 is engaged with the inside of the slot. The motor 702 is fixedly connected to one side of the bottom end of the mounting plate 701, and the output end of the motor 702 extends to the inside of the mounting plate 701 and is fixedly connected to the first transmission gear 703.

[0045] While adjusting the docking mechanism 8, the mounting plate 701 can be inserted into the slot. After the equipment is securely fixed, the motor 702 can be controlled to rotate. When the motor 702 rotates, it drives the transmission gear 1 703 to rotate synchronously. At this time, the transmission gear drives the gear ring to rotate. During the rotation of the gear ring, it drives the transmission gear 2 704 to rotate. Simultaneously, the transmission gear 2 704 drives the threaded transmission rod 706 to rotate synchronously. At this time, the threaded transmission rod 706 will gradually descend as it rotates, and at the same time, the threaded transmission rod 706 will pull the fixed top plate 707 to move vertically downward. As the device moves, the gripping drill rod 708 will also descend. In addition, during the descent, the gripping drill rod 708 will rotate under the action of the internal threads of the mounting plate 701. At this time, the gripping drill rod 708 will be in a rotating and descending state, so that the bottom end of the gripping drill rod 708 will drill into the ground, thereby gripping and fixing the equipment, thereby improving the stability of the equipment during use and preventing the equipment from tipping over. At the same time, in conjunction with the docking mechanism 8, the equipment can be effectively fixed and limited when encountering different ground surfaces, preventing damage to the equipment and resulting economic losses.

[0046] like Figures 4-6 As shown, the docking mechanism 8 includes an outer tube 801, a shrink tube 802, a telescopic rod 803, and a rotating sleeve 804. The bottom end of the shrink tube 802 is fixedly connected to the inner bottom end of the outer tube 801. The rotating sleeve 804 is threadedly connected to the inner top end of the outer tube 801. The output end of the telescopic rod 803 is movably connected to the rotating sleeve 804 and the inner end of the shrink tube 802. The top end of the telescopic rod 803 is fixedly connected to the inner end of the groove 6. The bottom end of the outer tube 801 is fixedly connected to the top end of the fixed top plate 707. The top end of the shrink tube 802 is trapezoidal, and the bottom end of the rotating sleeve 804 is movably connected to the top end of the shrink tube 802. The shrink tube 802 forms a rotating tightening structure through the rotating sleeve 804.

[0047] When the equipment encounters loose ground, simply remove the gripping drill rod 708 and the equipment itself. Then, insert the output end of the telescopic rod 803 into the rotating sleeve 804 and rotate the rotating sleeve 804. As the rotating sleeve 804 rotates, it gradually descends under the action of the threads. At this time, the bottom end of the rotating sleeve 804 gradually squeezes the top end of the shrink tube 802, causing the shrink tube 802 to shrink. The shrink tube 802 clamps and fixes the top end of the telescopic rod 803, thus preventing the equipment from loosening and falling during use or relocation. In addition, making the gripping drill rod 708 detachable makes it easier for personnel to store the equipment. Furthermore, this equipment makes it easier for personnel to operate, thereby reducing the difficulty of personnel work.

[0048] like Figures 2-9 As shown, the auxiliary mechanism 9 includes a docking plate 901, a return spring 902, a docking rod 903, a connecting plate 904, and a fixing rod 905. Multiple return springs 902 are provided, and one end of the return spring 902 is fixedly connected to the top of the docking plate 901. One end of the docking rod 903 is fixedly connected to the bottom of the docking plate 901, and the other end of the docking rod 903 is fixedly connected to the top of the connecting plate 904. The top of the fixing rod 905 is fixedly connected to the bottom of the connecting plate 904. The top of the docking plate 901 is rotatably connected to the bottom of the threaded transmission rod 706. The other end of the return spring 902 is fixedly connected to the bottom of the mounting plate 701.

[0049] As the threaded drive rod 706 rotates and descends, its bottom end pushes the top end of the docking plate 901. The docking plate 901, in turn, causes the connecting plate 904 to gradually descend. The push rod then inserts into the ground, further enhancing the equipment's stability. When it needs to be pulled out, simply reverse the rotation of the motor 702 to pull the push rod out through the threaded drive rod 706. This effectively reduces the difficulty of operation and minimizes wasted time. Furthermore, the auxiliary mechanism 9 prevents the gripping drill rod 708 from loosening and detaching from the ground during use, improving equipment safety.

[0050] Working principle: After the equipment is moved to the required location, the support rod 3 can be manually unfolded. The height of the equipment can then be adjusted using the support rod 3 and the movable rod 2 to measure the space. When the equipment encounters loose ground, simply remove the gripping drill rod 708 and the equipment itself. Then, insert the output end of the telescopic rod 803 into the rotating sleeve 804 and rotate the sleeve 804. As the sleeve rotates, it gradually descends due to the threaded action. The bottom of the sleeve 804 gradually presses against the top of the contraction tube 802, causing the contraction tube 802 to contract. At this point, the contraction tube 802 will... The top of rod 803 is clamped and fixed to prevent the equipment from loosening and falling during use or relocation. The gripping drill rod 708 is detachable for easier storage. While adjusting the docking mechanism 8, the mounting plate 701 can be inserted into the slot. After securing the equipment, the motor 702 can be rotated. The rotation of motor 702 drives transmission gear 1 703 to rotate synchronously. This transmission gear drives the gear ring to rotate, which in turn drives transmission gear 2 704 to rotate. This synchronously drives the threaded drive rod 706 to rotate. As the threaded drive rod 706 rotates, it gradually descends, simultaneously pulling the fixed top plate 707 vertically downwards. The gripping drill rod 708 also descends accordingly. Furthermore, during its descent, the gripping drill rod 708 rotates under the action of the internal threads of the mounting plate 701. This rotating descent allows the bottom end of the gripping drill rod 708 to drill into the ground, thus securing the equipment and improving its stability during use, preventing it from tipping over. In addition, the docking mechanism 8 can effectively fix and limit the equipment when it encounters different ground surfaces, preventing economic losses caused by equipment damage. Furthermore, when the threaded drive rod 706 rotates and descends, the bottom end of the threaded drive rod 706 will push the top end of the docking plate 901. At this time, the docking plate 901 will also drive the connecting plate 904 to gradually descend under the pushing action. At this time, the top rod will also be inserted into the ground under its action, thereby further improving the stability of the equipment. When it is necessary to pull it out, simply control the motor 702 to rotate in the opposite direction, and the threaded drive rod 706 will drive the top rod to pull it out of the ground.
