Description

Technical Field

[0001] This utility model relates to the field of remote sensing mapping technology, and in particular to an engineering surveying device based on remote sensing mapping technology. Background Technology

[0002] Sensing mapping technology can monitor urban land use in real time, providing information on urban expansion, building distribution, and changes in green space, helping urban planners make more scientific and rational decisions. Engineering surveying devices based on remote sensing mapping technology can be applied to various fields through the collection and analysis of geographic data, thereby providing strong data support for environmental protection, urban construction, disaster response, and resource management.

[0003] A search revealed Chinese Patent Publication No. CN216010283U, which discloses an engineering surveying device based on remote sensing mapping technology. The device includes a connecting base, a contact block in the middle of the connecting base, a contact rod fixedly connected to the inner surface of the connecting base, the contact rod making point contact with the contact block, a connecting shaft fixedly connected to the upper surface of the contact block, a remote sensing mapping instrument fixedly connected to the upper end of the connecting shaft, a leveling block movably connected to the right end of the remote sensing mapping instrument, and a knob fixedly connected to the right side of the leveling block. In this invention, a leveling block, a contact rod, and a counterweight are used to hold the remote sensing mapping instrument above the ground by the weight of the counterweight. Leveling is achieved by adjusting the distance between the leveling block and the remote sensing mapping instrument using the lever principle. Since the gravity on both sides of the connecting shaft is basically the same, slight adjustments are sufficient for leveling, achieving rapid leveling. Even if the device is moved, rapid mapping can still be performed. The aforementioned patent mentions in its specification that "a connecting block 7 is fixedly connected to the side of the connecting seat 1, the connecting blocks 7 are evenly distributed on the side of the connecting seat 1, a retractable rod 8 is movably connected inside the connecting block 7, a support rail 18 is provided on the inner side of the retractable rod 8, the inner surface of the support rail 18 is slidably connected to the support ring 13, a support rod 9 is slidably connected inside the retractable rod 8, a support foot 10 is fixedly connected to the end of the support rod 9 away from the retractable rod 8, a support ring 13 is movably connected to the outer surface of the retractable rod 8, and a support rod 12 is movably connected to the side of the support ring 13, the support rod 12 is movably connected to the side of the support ring 13, and the support rod 12 is movably connected to the side of the support ring 13, the support rod 12 is slidably connected to the side of the support ring 13, and the support rod 12 is slid ... One end of the support ring 13 is movably connected to a shrink block 11. The upper surface of the shrink block 11 is provided with a support rod shrink groove, which is connected to the support rod 12. Through the leveling block 3, contact rod 2, contact block 6 and counterweight 6, the remote sensing mapping instrument 4 can be held above by the gravity of the counterweight 14. The leveling is achieved by adjusting the distance between the leveling block 3 and the remote sensing mapping instrument 4 using the lever principle. Since the gravity on both sides of the connecting shaft 5 is basically the same, slight adjustment is sufficient for leveling, achieving the purpose of rapid leveling. Even if the device is moved, the effect of rapid mapping can be achieved. However, the mapping device does not have a protective mechanism during the mapping process, which cannot reduce the vibration and impact of accidental occurrences. Furthermore, the lack of a sunshade device cannot reduce the reflection and heat interference caused by sunlight and avoid image blurring and data deviation caused by excessive light. Therefore, in order to address the above shortcomings, an engineering mapping device based on remote sensing mapping technology is proposed to solve the above problems. Utility Model Content

[0048] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 4 includes a connecting shaft 401, which is externally fixedly connected to the inside of the rotating ring 3. A limiting ring 402 is rotatably connected to the outside of the connecting shaft 401. The limiting ring 402 rotates outside the connecting shaft 401 to fix the placement plate 403. The top of the connecting shaft 401 is fixedly connected to the placement plate 403, and the bottom of the placement plate 403 is fixedly connected to the top of the support column 1.

[0049] Specifically, the fixing mechanism 4 provides stable and flexible support and adjustment for the surveying equipment. The inward rotation of the limiting ring 402 can fix the placement plate 403, thereby ensuring the stability of the placement plate 403 during use. The placement plate 403 is fixedly connected to the gimbal base 404, providing a reliable support platform for the surveying equipment.

Three of the support rods 202 are connected to the outside of the support column 1 for diagonal triangular support and height adjustment. Multiple limiting holes are opened inside the lower end of the support rod 202. The limiting holes are used to place limiting rods for fixing after the height of the support rod 202 is adjusted.

At the same time, the connecting ring 206 slides outside the support rod 202, driving the support rod 202 to rotate. 2. The device slides inward for storage. A bubble level 207 is fixedly connected to the top of the sliding ring 204, and a fine-tuning knob 208 is also fixedly connected to the top of the sliding ring 204. A disassembly thread 209 is provided on the outer side of the top of the support column 1. The bubble level 207 and the fine-tuning knob 208 are used to precisely adjust the level and angle of the device to ensure the stability of the device during surveying. The overall storage mechanism 2 can be carried and transported via a backpack frame. The backpack frame is made of high-strength plastic material and has multiple fixing straps and hooks inside for fixing the remote sensing acquisition module and the support structure module. The back of the backpack frame is designed according to ergonomic principles and is equipped with comfortable shoulder straps and a waist belt to reduce the burden on the operator. The backpack frame has a folding handle installed on the side of the backpack frame. It adopts a foldable design, and the handle can be unfolded when the device needs to be moved, making it convenient for the operator to carry and drag. A storage bag is located at the bottom of the backpack frame for storing accessories such as tripods. The storage bag is made of waterproof and wear-resistant material and has multiple compartments inside for easy classification and storage of items.

[0051] Specifically, the storage mechanism 2 achieves adjustment and storage of the support structure through the close cooperation between the telescopic rods in multiple connecting plates 201 and the support column 1. The support rod 202 can be rotated to adjust the support angle. The support rod 202 ensures the stability of the height after adjustment through multiple limiting holes and limiting rods. The fixed shaft 203 further strengthens the fixation of the support rod 202 and avoids loosening during the adjustment process. The sliding ring 204 on the outside of the support column 1 can drive the folding plate 205 to rotate and make the connecting ring 206 slide along the outside of the support rod 202, thereby realizing the inward retraction and storage of the support rod 202. The top of the sliding ring 204 is equipped with a bubble level 207 and a fine adjustment knob 208, which can help the operator to accurately adjust the level and angle of the device and ensure the accuracy of the surveying. The entire storage mechanism 2 is conveniently carried through a backpack frame, which can reasonably classify and store accessories such as tripods, making the transportation of equipment safer and more efficient.

[0052] Working principle: During the surveying process, the optical camera 60501 and the sensing radar 60502 are fixed inside the fixed housing 5 through the protective housing 604. The lead screw 601 drives the clamping block 602 to firmly fix the protective housing 604 inside the fixed housing 5. At the same time, the slider 603 at the bottom of the clamping block 602 slides in the groove opened in the fixed housing 5. The optical camera 60501 is responsible for capturing ground images, while the sensing radar 60502 performs radar scanning to obtain richer ground information. The design of the protective mechanism 6 ensures the safety of the surveying component 605 in unstable environments. The soft pad 606 and the spring 60701 and damper 60702 in the buffer component 607 effectively absorb external impacts and protect the stability of the equipment. The connecting column 609 connects the support plate 608 and the sunshade 6010. The sunshade 6010 can rotate back and forth inside the connecting column 609. The main function of the sunshade 6010 is to prevent strong sunlight from directly hitting the surveying component 605 and affecting the measurement accuracy.

[0053] The placement plate 403 in the fixing mechanism 4 can be rotated and adjusted. After adjustment, the limiting ring 402 rotates outside the connecting shaft 401 to fix the placement plate 403. The top of the placement plate 403 has a gimbal base 404, and one side of the gimbal base 404 has a gimbal head 405. The gimbal base 404 and the gimbal head 405 work together to realize the free rotation and pitch adjustment of the surveying equipment.

[0054] The device is placed on the ground, and the support column 1 is precisely adjusted in terms of level and angle using the fine-tuning knob 208 and the bubble level 207 to ensure the stability of the device during surveying. Then, the external storage mechanism 2 of the support column 1 unfolds and fixes the support structure at the required height by rotating the connecting plate 201 and the support rod 202. The sliding ring 204 slides outside the support column 1, driving the folding plate 205 to rotate. At the same time, the connecting ring 206 slides outside the support rod 202, driving the support rod 202 to slide outward to unfold and conversely to retract, so as to form a stable support base. The support rod 202 is a telescopic rod that can be extended and retracted. After adjusting the height of the telescopic rod, it can be fixed by using the fixing shaft 203 to lock into the limiting hole opened inside the support rod 202. After the surveying is completed, the operator can disassemble the top structure by rotating the rotating ring 3 through the disassembly thread 209 on the outside of the support column 1 for easy transportation.
