Description

Technical Field

[0001] The invention belongs to the technical field of remote sensing measurement, in particular to a remote sensing measurement stand and a use method thereof. Background Art

[0002] Remote sensing measurement is a technical means of obtaining information about the earth's surface through sensors, which can achieve efficient, rapid and accurate observation and monitoring of the earth's surface. Remote sensing measurement technology is widely used in many fields, including land and resources surveys, environmental monitoring, climate change, disaster warning, etc.

[0003] There are many ways to classify remote sensing. According to the definition of remote sensing, the common classification methods are as follows: ground remote sensing, aerial remote sensing, and space platform remote sensing;

[0004] Among them, ground remote sensing refers to placing sensors on ground platforms, usually no more than 150 meters away from the ground, such as vehicle-mounted, ship-mounted, portable, fixed or movable elevated platforms, etc. Ground platforms include tripods, remote sensing towers, remote sensing vehicles (ships), the tops of buildings, etc., which are mainly used to measure the spectrum of ground objects at close range and obtain detailed images of ground objects, and to calibrate and assist in aerial remote sensing and aerospace remote sensing.

[0005] In some areas with poor road conditions, such as rugged mountain roads and muddy roads, it may be difficult for remote sensing vehicles to reach the observation site, so people can only walk to the observation site manually and use a tripod to set up remote sensing measurement instruments for observation;

[0006] When using a tripod to set up a remote sensing measuring instrument for observation, it is necessary to manually unfold the tripod and adjust it to a suitable height, and then install the remote sensing measuring equipment on the pan-tilt platform; then the remote sensing measuring instrument is precisely adjusted, and once the adjustment is completed, measurement can then be carried out;

[0007] During the measurement process, if the position of the remote sensing measuring instrument needs to be adjusted upward or downward according to the measurement requirements, the height of the legs needs to be manually adjusted before the position of the measuring instrument can be adjusted. When the legs are adjusted, the measuring angle of the remote sensing measuring instrument changes, so the position of the remote sensing measuring instrument needs to be readjusted.

Compared with the equipment in the prior art that can adjust the instrument height, the measuring stand can be adjusted downward at the original basic position for measurement, and there is no need to adjust the first leg and the second leg for adjustment. There is no need to configure additional motorized components, and it is suitable for more complex use environments, such as underwater, mountainous, muddy and other environments, so that the measuring stand has certain practicality and universality.

[0039] 2. A remote sensing measurement stand and a method of use described in the present invention, when the mounting seat drives the remote sensing measurement instrument to move upward or downward to a suitable position, the guide rod is manually rotated 180 degrees. During the rotation of the guide rod, the arcuate tooth grooves on the guide rod will gradually engage with the arcuate gear teeth. After the guide rod is rotated 180 degrees, the arcuate tooth grooves and the arcuate gear teeth can fully engage with each other. At this time, the arcuate gear teeth can support and limit the guide rod, thereby preventing the mounting seat and the remote sensing measurement instrument from sliding downward under their own gravity, thereby causing the position of the remote sensing measurement instrument to change, causing the position measured by the remote sensing measurement instrument to change, which will affect the measurement process of the remote sensing measurement instrument.

[0040] 3.

DETAILED DESCRIPTION

[0052] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0053] Embodiment 1: Figures 1 to 9 As shown, on one hand, the present invention discloses a remote sensing measurement stand, including a stand structure; the stand structure includes an annular disk 1; the annular disk 1 is provided with uniformly arranged first through holes 11;

[0054] An annular groove 12 is provided on the inner ring surface of the annular disk 1, and the annular groove 12 is connected to the first through hole 11; a mounting seat 13 is provided on the top of the annular disk 1; a pan head 14 is installed on the top of the mounting seat 13, and the pan head 14 is used to install a remote sensing measuring instrument;

[0055] The bottom of the mounting seat 13 is fixedly connected to evenly arranged threaded rods 15, and the number of the threaded rods 15 is the same as the number of the first through holes 11, and the threaded rods 15 pass through the corresponding first through holes 11;

[0056] A threaded disc 16 is rotatably connected in the annular groove 12, and a thread is formed on the outer surface of the threaded disc 16; the thread of the outer surface of the threaded disc 16 is threadedly engaged with the threaded rod 15 passing through the first through hole 11;

[0057] A limiting mechanism is provided between the annular disk 1 and the mounting seat 13, and a locking mechanism is used to limit the position of the mounting seat 13;

[0058] The threaded disk 16 is provided with a limit ring 17 at the top and bottom, and the limit ring 17 is fixedly connected to the annular disk 1; the middle of the threaded disk 16 is fixedly connected to the rotating drum 2; the top of the rotating drum 2 is located at the bottom of the mounting seat 13 and is fixedly connected to a round rod 21, and the round rod 21 extends into the rotating drum 2;

[0059] A first leg 22 is rotatably mounted at the bottom of the drum 2; a first slide groove is provided in the first leg 22; a first insertion rod 23 is slidably connected in the first slide groove; a first locking bolt 24 is threadedly engaged on the first leg 22, and the first locking bolt 24 is used to lock the first insertion rod 23;

[0060] The outer ring surface of the annular disk 1 is hinged with uniformly arranged second legs 25; each of the second legs 25 is provided with a second slide groove; a second plunger 26 is slidably connected in the second slide groove; a second locking bolt 27 is threadedly engaged on the second legs 25, and the second locking bolt 27 is used to lock the second plunger 26;

[0061] Specifically, when using the remote sensing measuring instrument for measurement, the staff first unfolds the second leg 25, and then pulls out the first plug rod 23 and the second plug rod 26 in the first leg 22 and the second leg 25. When the first plug rod 23 and the second plug rod 26 are pulled out to a suitable position, the first plug rod 23 is locked and fixed by the first locking bolt 24, and then the second plug rod 26 is locked and fixed by the second locking bolt, and the first plug rod 23 and the second plug rod 26 are inserted into the ground, and then the remote sensing measuring instrument is installed on the pan-tilt head 14, and the remote sensing measuring instrument is accurately adjusted. After the remote sensing measuring instrument is fine-tuned, the remote sensing measuring instrument can be used for measurement;

[0062] More specifically, when the remote sensing measuring instrument needs to be adjusted downward from the original measuring base position, the rotating drum 2 is manually rotated counterclockwise, and the rotating drum 2 will rotate along the round rod 21, and the rotating drum 2 will drive the threaded disk 16 to rotate counterclockwise. Since the threads on the outer ring surface of the threaded disk 16 are engaged with the threads of the threaded rod 15 passing through the first through hole 11, the threaded disk 16 will gradually push the multiple threaded rods 15 to move downward during the counterclockwise rotation of the threaded disk 16, and the threaded disk 16 will gradually engage with the threads of the threaded rod 15 located above the first through hole 11. During the gradual downward movement of the multiple threaded rods 15, the mounting seat 13 will be driven downward, and the mounting seat 13 will drive the round rod 21, the pan-tilt head 14 and the remote sensing measuring instrument installed on the pan-tilt head 14 to move downward. When the remote sensing measuring instrument moves down to the measuring position, the measurement can continue.

[0063] Furthermore, when the remote sensing measuring instrument needs to be adjusted upward from the original basic position for measurement, the rotating drum 2 is first controlled to rotate clockwise, and the rotating drum 2 rotating clockwise will drive the threaded disk 16 to rotate clockwise, and the threaded disk 16 rotating clockwise will engage with the thread on the threaded rod 15 located in the first through hole 11, thereby gradually pushing the threaded rod 15 to move upward, and in the process of the threaded rod 15 moving upward, the mounting seat 13 will be driven to move upward, and the upwardly moving mounting seat 13 will drive the round rod 21, the pan-tilt head 14 and the remote sensing measuring instrument on the pan-tilt head 14 to move upward, and when the remote sensing measuring instrument moves upward to the original basic position for measurement of the remote sensing measuring instrument, the rotating drum 2 is continued to be rotated at this time, thereby driving the mounting seat 13 and the remote sensing measuring instrument to move upward, and when the remote sensing measuring instrument moves upward to the measurement position, measurement can be performed;

[0064] Furthermore, in the process of controlling the mounting seat 13 to move upward or downward by rotating the drum 2, due to the existence of the limiting mechanism, the limiting mechanism can limit the mounting seat 13 after adjustment, thereby preventing the mounting seat 13 from sliding down due to its own gravity after moving upward or downward;

[0065] By controlling the rotating drum 2 to rotate clockwise or counterclockwise, the remote sensing measuring instrument can be controlled to move downward or upward without adjusting the first leg 22 and the second leg 25, thereby avoiding that when the height of the remote sensing measuring instrument is adjusted by adjusting the first leg 22 and the second leg 25, the measuring angle of the remote sensing measuring instrument will change, so that manual adjustment is required before continuing the measurement, thereby increasing the operation steps of the remote sensing measuring instrument during measurement. Compared with the equipment in the prior art that can adjust the height of the instrument, the measuring stand can be adjusted downward at the original basic position of the measurement without adjusting the first leg 22 and the second leg 25. No additional motorized components are required, and it is suitable for more complex use environments, such as water, mountains, muddy ground and other environments, so that the measuring stand has certain practicality and universality.

[0066] Embodiment 2: The limiting mechanism includes a second through hole 3; a second through hole 3 is provided on the annular disk 1 between two adjacent first through holes 11, and the second through hole 3 is not connected to the annular groove 12;

[0067] A guide rod 31 is rotatably connected between two adjacent threaded rods 15 on the mounting seat 13, and the guide rod 31 passes through the opposite second through holes 3;

[0068] In this embodiment, the guide rod 31 is a semicircular rod 21; the arc surface of the guide rod 31 is provided with arc-shaped tooth grooves 32 arranged evenly;

[0069] The second through hole 3 is fixedly connected with arc-shaped gear teeth 33 arranged evenly. In the initial state, the arc-shaped gear teeth 33 are meshed with the arc-shaped tooth grooves 32 provided on the guide rod 31;

[0070] Specifically, since the arcuate gear teeth 33 are meshed with the arcuate tooth grooves 32 provided on the guide rod 31 in the initial state, when the position of the remote sensing measuring instrument needs to be adjusted, the guide rod 31 is first rotated 180 degrees. During the rotation of the guide rod 31, the arcuate tooth grooves 32 provided on the guide rod 31 will gradually stagger with the arcuate gear teeth 33. After the guide rod 31 is rotated 180 degrees, the arcuate tooth grooves 32 on the guide rod 31 are completely staggered with the arcuate gear teeth 33 in the second through hole 3. Subsequently, when the mounting seat 13 follows the threaded rod 15 to move upward or downward, the mounting seat 13 will drive the guide rod 31 to move upward or downward in the second through hole 3. When the mounting seat 13 drives the remote sensing measuring instrument After the remote sensing measuring instrument moves upward or downward to a suitable position, the guide rod 31 is manually rotated 180 degrees. During the rotation of the guide rod 31, the arcuate tooth groove 32 on the guide rod 31 will gradually mesh with the arcuate gear teeth 33. After the guide rod 31 rotates 180 degrees, the arcuate tooth groove 32 and the arcuate gear teeth 33 can fully mesh. At this time, the arcuate gear teeth 33 can support and limit the guide rod 31, thereby preventing the mounting seat 13 and the remote sensing measuring instrument from sliding downward under their own gravity, thereby causing the position of the remote sensing measuring instrument to change, causing the position measured by the remote sensing measuring instrument to change, which will affect the measurement process of the remote sensing measuring instrument.

[0071] Embodiment 3: A third sliding groove is provided in each of the threaded rods 15;

[0072] A long rod 4 is slidably connected in the third sliding groove, and the long rod 4 extends between the first leg 22 and the second leg 25; two mounting blocks 41 are fixedly connected to one side surface of the long rod 4 facing the first leg 22 and the second leg 25;

[0073] A stopper 42 is provided between the two mounting blocks 41; the stopper 42 is located at one side between the two mounting blocks 41 and is fixedly connected to a rotating rod 43, and the rotating rod 43 rotates on the two mounting blocks 41;

[0074] The first leg 22 and the second leg 25 are provided with a plug hole 28, and the diameter of the plug hole 28 is the same as the diameter of the stop rod 42;

[0075] In this embodiment, the first leg 22 and the second leg 25 are provided with evenly arranged insertion holes 28;

[0076] In this embodiment, each of the insertion holes 28 is a threaded hole;

[0077] The push rod 42 comprises a threaded shaft 421 and a threaded barrel 422; the threaded shaft 421 is rotatably mounted between the two mounting blocks 41 via a rotating rod 43; the threaded barrel 422 is engaged with the threaded shaft 421 via a threaded sleeve;

[0078] The outer surface of the threaded barrel 422 is also provided with threads, and the threads provided on the outer surface of the threaded barrel 422 are engaged with the threads in the insertion hole 28;

[0079] Specifically, when the platform structure is unfolded and inserted into the ground, the long rod 4 is manually pulled downward, and the long rod 4 will gradually move downward in the third slide groove, and the long rod 4 will drive the push rod 42 to move downward during the downward movement. When the push rod 42 moves down to the position of the first insertion rod 23 and the second insertion rod 26, the push rod 42 is rotated at this time, and the two push rods 42 are aligned with the insertion holes 28 on the first leg 22 and the second leg 25 respectively, and then the threaded cylinder 422 is rotated, the threaded cylinder 422 will rotate along the threaded shaft 421, and the threaded cylinder 422 will gradually disengage from the threaded shaft 421. At this time, the overall length of the push rod 42 gradually becomes longer, and then the threaded cylinder 422 is inserted into the insertion hole 28. In the process of rotating the threaded cylinder 422, the thread on the outer ring of the threaded cylinder 422 will gradually engage with the thread in the insertion hole 28, so the threaded cylinder 422 will gradually extend into the insertion hole 28 and gradually engage with the corresponding The first plug rod 23 or the second plug rod 26 abuts against each other. When the threaded cylinder 422 abuts against the first plug rod 23 or the second plug rod 26, the threaded cylinder 422 is stopped from rotating. In this process, the threaded cylinder 422 is rotated into the insertion hole 28 and abuts against the first plug rod 23 or the second plug rod 26, so that the first plug rod 23 and the second plug rod 26 can be further locked and fixed, thereby further improving the degree of fixation of the first plug rod 23 and the second plug rod 26, and preventing the first plug rod 23 or the second plug rod 26 from sliding into the first leg 22 or the second leg 25 during the use of the stand structure, thereby changing the position of the entire stand structure, causing the position of the remote sensing measuring instrument to change, thereby affecting the measuring process of the remote sensing measuring instrument, and at the same time, it can be prevented that the rotating cylinder 2 will drive the first leg 22 to rotate during the rotation of the rotating cylinder 2;

[0080] More specifically, since the first leg 22 and the second leg 25 are provided with evenly arranged insertion holes 28, when it is necessary to insert the push rod 42 into the insertion hole 28, the insertion hole 28 into which the rod is inserted can be determined based on the extended length of the first insertion rod 23 or the second insertion rod 26. If the first insertion rod 23 or the second insertion rod 26 is pulled out too long, a longer distance can be pulled when the long rod 4 is pulled down, thereby ensuring that the insertion hole 28 into which the push rod 42 is inserted can abut against the first insertion rod 23 or the second insertion rod 26, thereby avoiding the existence of a single insertion hole 28. When the first insertion rod 23 or the second insertion rod 26 moves down to below the insertion hole 28, it is impossible to abut against the first insertion rod 23 or the second insertion rod 26.

[0081] Embodiment 4: The outer circumferential surface of the rotating rod 43 fixedly connected to the supporting rod 42 is provided with threads; the rotating rod 43 is threadedly engaged with a locking nut 44;

[0082] In this embodiment, the long rod 4 is a rectangular rod;

[0083] Specifically, when the push rod 42 is inserted into the insertion hole 28 and abuts against the first plug rod 23 or the second plug rod 26, the locking nut 44 is rotated, and the locking nut 44 rotates along the rotating rod 43 and gradually approaches the mounting block 41. When the locking nut 44 contacts the mounting block 41, the rotating rod 43 is locked on the mounting block 41 by the locking nut 44, so that the push rod 42 can be locked and fixed in the mounting block 41. In this process, the first leg 22, the long rod 4 and the second leg 25 can form a stable structure, thereby improving the stability of the stand structure.

[0084] More specifically, when the threaded rod 15 moves upward or downward, the threaded rod 15 will move upward or downward along the long rod 4, so that the long rod 4 can be used to limit the threaded rod 15 moving up and down. Since the long rod 4 is a rectangular rod, the limiting effect on the threaded rod 15 can be further improved.

[0085] On the other hand, the present invention also provides a method for using a remote sensing measurement stand, which is applicable to the above-mentioned remote sensing measurement stand. The specific method of use is as follows:

[0086] Step 1: First, the staff unfolds the second leg 25, and inserts the first plug rod 23 and the second plug rod 26 into the ground, then installs the remote sensing measuring instrument on the pan-tilt platform 14, and accurately adjusts the remote sensing measuring instrument, and then the measurement can be carried out;

[0087] Step 2: When the remote sensing measuring instrument needs to be adjusted downward from the original basic position for measurement, the rotating drum 2 is manually rotated counterclockwise, and the rotating drum 2 will push the multiple threaded rods 15 to gradually move downward through the threaded disk 16, thereby driving the mounting seat 13 and the remote sensing measuring instrument to move downward. After reaching the appropriate position, measurement can be carried out;

[0088] Step 3: When the remote sensing measuring instrument needs to be adjusted upward from the original basic position for measurement, the rotating drum 2 is controlled to rotate clockwise. The rotating drum 2 rotating clockwise will push the multiple threaded rods 15 to gradually move upward through the threaded disk 16, thereby driving the mounting seat 13 and the remote sensing measuring instrument to move upward. After reaching the appropriate position, measurement can be carried out;

[0089] Step 4: After the measurement using the remote sensing measuring instrument is completed, the remote sensing measuring instrument is removed from the pan-tilt platform 14 and the platform structure is folded up.

[0090] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
