Abstract
Description
Technical Field
[0001] This invention belongs to the field of geographic exploration device technology, and specifically relates to a geological disaster field monitoring device. Background Technology
[0002] Currently, some detection and monitoring equipment is placed in places that are difficult for humans to reach, such as high mountains and snow-capped peaks, to monitor and predict geological disasters. For example, the invention with patent number CN216049752U discloses a drone-dropped displacement monitoring device based on a navigation system. This device is a geological disaster field monitoring device designed, manufactured, and put into use by our company last year. It is dropped by a drone to high mountains and snow-capped peaks, and uses a navigation system to measure the displacement of the mountain. Using data processing technology, it can then determine whether a geological disaster has occurred.
[0003] However, during our use of this device, we found that its reliance solely on measuring mountain displacement to determine geological hazards was too simplistic and prone to significant errors. Therefore, we improved upon the aforementioned device and proposed a more accurate field monitoring device for geological hazards. Summary of the Invention
[0004] This invention provides a field monitoring device for geological disasters, which solves the technical problem that existing monitoring devices of this type only rely on monitoring mountain displacement to determine whether a geological disaster has occurred, resulting in a large judgment error.
[0005] This invention is achieved through the following technical solution: a geological disaster field monitoring device, comprising:
[0006] Tetrahedral framework;
[0007] The positioning part is fixedly connected to the center position of the regular tetrahedral frame by a connecting rod, and the positioning part is used to detect the displacement of the mountain.
[0008] The acoustic sensing unit includes a first connecting rod connected to the tetrahedral frame and a second connecting rod connected to the outer wall of the positioning part. The acoustic sensing unit includes a sealed outer shell, a spherical shell, an infrasound sensor, a lithium battery, and a processing chip integrating a signal transmission module. The first connecting rod and the second connecting rod are both connected to the outer wall of the sealed outer shell. The sealed outer shell is filled with a buffer solution, and the spherical shell is suspended in the buffer solution. The infrasound sensor, the lithium battery, and the processing chip are all installed inside the spherical shell, and the infrasound sensor and the lithium battery are electrically connected to the processing chip.
[0009] Furthermore, in order to better realize the present invention, the spherical shell includes a first hemispherical shell and a second hemispherical shell, the first hemispherical shell and the second hemispherical shell are joined together to form a complete sphere, and the first hemispherical shell and the second hemispherical shell are fixed together by adhesive. A rubber sleeve is also provided on the outside of the spherical shell, and the infrasound sensor, the lithium battery and the processing chip are all installed on the first hemispherical shell.
[0010] Furthermore, in order to better realize the present invention, the first hemispherical shell is provided with a mounting plate, and the mounting plate is provided with at least three mounting slots, namely a first mounting slot, a second mounting slot and a third mounting slot. The second mounting slot is located between the first mounting slot and the third mounting slot. The infrasound sensor is bolted in the first mounting slot, the processing chip is bonded in the second mounting slot, and the lithium battery is bolted in the third mounting slot.
[0011] Furthermore, in order to better realize the present invention, the buffer solution is a viscous liquid.
[0012] Furthermore, in order to better realize the present invention, the positioning unit includes a housing and a global navigation satellite system and a Beidou short message terminal installed in the housing. The global navigation satellite system and the Beidou short message terminal are both communicatively connected to the navigation and positioning satellite, and the navigation and positioning satellite is also communicatively connected to the reference unit.
[0013] Furthermore, in order to better realize the present invention, the sealed outer shell is spherical in shape, and a cushioning pad is attached to the inner wall of the sealed outer shell.
[0014] Furthermore, in order to better realize the present invention, the buffer pad is a rubber sheet.
[0015] Furthermore, in order to better realize the present invention, a counterweight is also installed on the mounting plate. The counterweight is located in the first hemispherical shell, and the counterweight and the mounting groove are respectively disposed on both sides of the mounting plate.
[0016] Furthermore, in order to better realize the present invention, the total weight of the spherical shell, the rubber sleeve, the mounting plate, the counterweight, the lithium battery, the processing chip, and the infrasound sensor is the same as the buoyancy force on the spherical shell in the buffer solution.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] The geological disaster field monitoring equipment provided by this invention uses a positioning unit to detect mountain displacement and a sound sensor to listen to the infrasound waves emitted when a geological disaster occurs. Therefore, the equipment can determine whether a geological disaster has occurred by combining mountain displacement and infrasound waves, which is more accurate. Specifically, the infrasound sensor installed in the acoustic sensing unit detects infrasound waves, and the infrasound sensor sends the detected signals to a remote terminal through a processor. A lithium battery powers the infrasound sensor and the processing chip. The lithium battery, infrasound sensor, and processing chip are all installed in the spherical shell of the acoustic sensing unit. The spherical shell is suspended in a buffer solution inside the sealed outer shell. Since the geological disaster field monitoring equipment is transported to a remote, high-altitude location by being dropped by a drone, it will experience rollover and / or strong shaking upon landing. Unlike the positioning unit, the infrasound sensor is a high-precision component with a lower vibration tolerance. Therefore, by suspending the spherical shell in the buffer solution, most of the vibration energy generated and transmitted to the acoustic sensing unit upon landing is absorbed by the buffer solution, resulting in very little vibration energy transmitted to the spherical shell and greatly reducing the probability of damage to the infrasound sensor during the dropping process.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0031] Example 1:
[0032] This embodiment provides a geological disaster field monitoring device to solve the technical problem of large errors caused by the use of a single means to monitor geological disasters in existing devices.
[0033] The geological disaster field monitoring equipment provided in this embodiment includes a tetrahedral frame 1, a positioning unit 2, and a sound sensing unit 4, wherein:
[0034] The tetrahedral frame 1 and the positioning unit 2 are the same as in the prior art, so they will not be described in detail here. The positioning unit 2 is used to detect mountain displacement. Specifically, the positioning unit 2 includes a shell and a global navigation satellite system and a Beidou short message terminal installed inside the shell. The global navigation satellite system and the Beidou short message terminal are both connected to the navigation and positioning satellites, which are also connected to a reference unit. The reference unit is fixedly installed at a certain location in the field, such as a mountaintop without glaciers. It serves as a reference body to determine a fixed point. In this way, the global navigation satellite system can monitor the displacement change of the positioning unit 2 relative to the reference unit in real time. When the displacement change reaches a certain level, it can be determined that a geological disaster will occur. The aforementioned positional change is usually caused by mountain displacement, so the positioning unit 2 is used to detect mountain displacement. The positioning unit 2 is fixedly connected to the center of the tetrahedral frame 1 by a connecting rod 3.
[0035] The acoustic sensor 4 is used to detect the infrasound waves emitted when a geological disaster occurs. The connecting rod 3 includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 is connected to the tetrahedral frame 1, and the second connecting rod 32 is connected to the outer wall of the positioning part 2. Both the first connecting rod 31 and the second connecting rod 32 are connected to the acoustic sensor 4. Specifically, the acoustic sensor 4 is located in the middle of the first connecting rod 31 and the second connecting rod 32. Both the first connecting rod 31 and the second connecting rod 32 are straight rods and are coaxially arranged. The arrangement of the acoustic sensor 4 and the positioning part 2 allows the geological disaster field monitoring equipment provided in this embodiment to not only monitor mountain displacement but also monitor the infrasound waves emitted when a geological disaster occurs. The two monitoring methods are used in combination to more accurately predict, judge, and monitor whether a geological disaster will occur.
[0036] The aforementioned acoustic sensor 4 includes a sealed outer shell 41, a spherical shell 43, an infrasound sensor 45, a lithium battery 46, and a processing chip 47 integrating a signal transmission module. The first connecting rod 31 and the second connecting rod 32 are both connected to the outer wall of the sealed outer shell 41. Specifically, the first connecting rod 31 and the second connecting rod 32 can be integrally formed with the sealed outer shell 41, or they can be detached and welded together. A buffer solution 5 is filled inside the sealed outer shell 41, and the spherical shell 43 is suspended in the buffer solution 5. The infrasound sensor 45, the lithium battery 46, and the processing chip 47 are all installed inside the spherical shell 43, and the infrasound sensor 45 and the lithium battery 46 are electrically connected to the processing chip 47.
[0037] The aforementioned acoustic sensor detects infrasound, and the infrasound sensor 45 sends the detected signals to a remote terminal via a processor. The lithium battery 46 powers the infrasound sensor 45 and the processing chip 47. The lithium battery 46, the infrasound sensor 45, and the processing chip 47 are all installed in the spherical shell 43 of the acoustic sensing part 4. The spherical shell 43 is suspended in the buffer solution 5 inside the sealed outer shell 41. Since the geological disaster field monitoring equipment is transported to a remote high place by being dropped by a drone, it will roll and / or shake violently during landing. Unlike the positioning part 2, the infrasound sensor 45 is a high-precision component with a low vibration tolerance. Therefore, by suspending the spherical shell 43 in the buffer solution 5, most of the vibration energy generated and transmitted to the acoustic sensing part 4 during landing is absorbed by the buffer solution 5, thereby making the vibration energy transmitted to the spherical shell 43 very small and greatly reducing the probability of damage to the infrasound sensor 45 during the dropping process.
[0038] Optionally, the aforementioned spherical shell 43 includes a first hemispherical shell 431 and a second hemispherical shell 432, which are joined together to form a complete sphere. The first hemispherical shell 431 and the second hemispherical shell 432 are bonded together with strong adhesive. A rubber sleeve 44 is also fitted over the spherical shell 43, completely covering it. This rubber sleeve 44 provides a seal, preventing the buffer solution 5 from entering the hemispherical shell. The rubber sleeve 44 can be glued to the outer wall of the spherical shell 43, or it can be installed on the outer wall of the spherical shell 43 using a two-color injection molding process. The aforementioned infrasound sensor 45, electromagnetic induction generator, and processing chip 47 are all mounted on the first hemisphere. Specifically, the first hemispherical shell 431 is provided with a mounting plate 433, which, together with the first hemispherical shell 431, forms a closed shell structure. The mounting plate 433 has at least three mounting slots: a first mounting slot, a second mounting slot, and a third mounting slot. The second mounting slot is located between the first and third mounting slots. The infrasound sensor 45 is bolted to the first mounting slot, the processing chip 47 is bonded to the second mounting slot, and the lithium battery 46 is bolted to the third mounting slot. The infrasound sensor 45, the processing chip 47, and the lithium battery 46 are all located outside the closed shell structure.
[0039] During installation, the processing chip 47, the infrasound sensor 45, and the lithium battery 46 are first mounted on the mounting plate 433. Then, the second hemispherical shell 432 is placed over the first hemispherical shell 431 and secured with adhesive hinges. Finally, the rubber sleeve 44 is fitted over the spherical shell 43. Because infrasound has strong penetrating power, even when installed in a confined space, the infrasound sensor 45 can still receive infrasound emitted during geological disasters.
[0040] Optionally, the buffer solution 5 is a viscous liquid, such as hydraulic oil, lubricating oil, phenolic resin liquid, liquid mercury, etc. When the entire device flips or vibrates, the sealed shell will move along with the buffer solution 5 inside it. The spherical shell 43 suspended in the buffer solution 5 is driven to remain stationary in the initial stage. Therefore, the buffer solution 5 will move relative to the spherical shell 43. Conversely, the spherical shell 43 will also move relative to the buffer solution 5. At this time, the spherical shell 43 will be subjected to the reverse resistance applied by the buffer solution 5. This reverse resistance prevents the spherical shell 43 from making a strong impact on the inner wall of the sealed shell. Therefore, the spherical shell 43 suspended in the buffer solution 5 will not make a strong impact on the inner wall of the sealed shell, thus protecting the spherical shell 43. Moreover, the rubber sleeve 44 not only plays a sealing role, but also buffers a certain degree of impact force when the spherical shell 43 collides with the inner wall of the sealed shell 41.
[0041] Of course, the buffer solution 5 mentioned above can also be a liquid composed of water with added thickener. Moreover, the buffer solution 5 can also be water.
[0042] More preferably, the sealed outer shell 41 is spherical, and the inner diameter of the sealed outer shell 41 is 4-10 times the outer diameter of the spherical shell 43. This reduces the probability of the spherical shell 43 colliding with the sealed outer shell 41. A buffer pad 42, which is a rubber sheet, is also attached to the inner wall of the sealed outer shell 41. The buffer pad 42 further buffers the impact force between the spherical shell 43 and the inner wall of the sealed outer shell 41.
[0043] Of course, the sealed outer shell 41 includes a spherical box with an opening, and a lid is welded to the opening of the spherical box. The buffer solution 5 and the spherical shell 43 enter the spherical box through the opening.
[0044] More preferably, a counterweight 434 is also installed on the mounting plate 433. The counterweight 434 is located in the first hemispherical shell 431, and the counterweight 434 and the mounting groove are respectively located on both sides of the mounting plate 433. The arrangement of the counterweight 434 makes the overall weight inside the first hemispherical shell 431 greater than that of the second hemispherical shell 432. In this way, in a static state, the heavier first hemispherical shell 431 will automatically rotate to the bottom of the second hemispherical shell 432 in the buffer solution, with the lithium battery 46, the processing chip 47, and the infrasound sensor 45 facing upwards. Moreover, the total weight of the spherical shell 43, the rubber sleeve 44, the mounting plate 433, the counterweight 434, the lithium battery 46, the processing chip 47, and the infrasound sensor 45 is the same as the buoyancy force on the spherical shell 43 in the buffer solution 5, thereby ensuring that the spherical shell 43 is suspended in the buffer solution 5. Of course, even when it finally comes to rest, the spherical shell 43 may sink to the bottom of the buffer body 5 and come into contact with the inner wall of the sealed shell 41, but this will not affect the normal operation of the infrasound sensor 45 and the processing chip 47.
[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
