[0002] Microseismic exploration is a geophysical exploration technique that utilizes natural microseismic signals on the Earth's surface. It has significant advantages such as no need for artificial seismic sources and being environmentally friendly, and plays an important role especially in the exploration of shallow underground structures in cities. With the wide application of microseismic exploration technology, the scale of exploration arrays has gradually increased, and a microseismic exploration array requires dozens of sets of instruments. Currently, the traditional method is usually to measure the angle using a compass at the center of the array and then measure the distance in combination with a tape measure or a measuring rope to determine the positions of instruments such as seismographs in the array. However, this method not only has low efficiency, but also with the increase in the number of instruments and the expansion of the array scale, its measurement accuracy is significantly reduced, making it difficult to meet the high-precision exploration requirements in the complex environment of modern cities. Therefore, the present invention provides an array layout device to improve the efficiency and accuracy of array layout.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. A device for arranging a micro - motion detection array based on laser. The control terminal includes a terminal control module, a terminal communication module, and an input module. The terminal control module has built - in algorithms. The laser indicator includes a support chassis, a support frame, a laser generator, a locator, a laser rangefinder, a vertical servo motor, a horizontal servo motor, an angle measuring instrument, an indicator communication module, and an indicator control module. The leveling base is respectively connected to the support chassis and the support frame. The indicator communication module transmits electrical signals to the terminal communication module. During application, first place the array arranging device in the micro - motion detection area and fix the support frame. Then, adjust the leveling base to make the laser indicator in a horizontal state. Next, input the relevant parameters of the array through the input module and transmit them to the terminal control module. At the same time, the laser rangefinder in the laser indicator measures the vertical height between the laser indicator and the ground, and the locator obtains the position information of the laser indicator and transmits the information to the terminal communication module through the indicator communication module, and finally it is received by the terminal control module. The terminal control module calculates the pitch angle and horizontal angle between the laser indicator and the instrument through the built - in algorithm based on this information. Then, the pitch angle and horizontal angle are finally received by the indicator control module. The indicator control module respectively controls the vertical servo motor and the horizontal servo motor to rotate in the vertical and horizontal directions, thereby driving the movement of the laser generator. During the rotation process, the rotation angle is measured in real - time by the angle measuring instrument until the angle meets the requirements, so that the positioning laser emitted by the laser generator accurately points to the position of the instrument in the array, completing the arrangement of the instrument. Since the built - in algorithm of the terminal control module can automatically calculate and determine the accurate position of the instrument in the array according to the input array parameters and the information fed back by the rangefinder and the locator, at the same time, the indicator control module can automatically control the vertical servo motor and the horizontal servo motor to rotate in the vertical direction (0 - 90°) and the horizontal direction (0 - 360°) according to the instructions of the terminal control module, enabling the device to automatically adjust the direction of the laser generator, so that the positioning laser emitted by the laser generator accurately points to the position of the instrument in the array. Compared with the prior art, the present invention does not require manual calculation of the angle that the laser generator needs to move and adjustment of the position of the laser generator, thus saving labor and time costs, and further improving the accuracy and efficiency of array arrangement. Therefore, the present invention can not only carry out the arrangement of the micro - motion detection array, but also has relatively high accuracy and efficiency in array arrangement.

[0017] 2. In the device for arranging a micro - motion detection array based on laser of the present invention, a bearing is installed in the middle of the top surface of the support chassis. The outer ring of the bearing is fixedly connected to the support chassis, and the inner ring of the bearing is fixedly connected to the bottom surface of the support frame. During application, the inner ring of the bearing in the middle of the top surface of the support chassis provides stable support for the support frame, making the bottom surface of the support frame and the top surface of the support chassis in the same plane, providing stable support and good levelness for the laser generator, and at the same time ensuring the rotational freedom of the laser generator in the vertical direction, ensuring the accuracy and stability of the movement, thereby improving the pointing accuracy and stability of the laser indicator. Therefore, the present invention not only improves the accuracy of array arrangement but also improves the stability of array arrangement.

[0018] 3. In the device for arranging a micro - motion detection array based on laser of the present invention, the laser generator includes a red - light laser generator and a green - light laser generator. During application, according to the surrounding site environment during micro - motion exploration, the brightness of the positioning laser emitted by the laser generator is adjusted through the control terminal or the color of the laser generator is switched to ensure that the laser indication is clearly visible, thereby improving the efficiency and accuracy of arrangement, making the device more universal and applicable to different site environments. Therefore, the present invention not only improves the stability of array arrangement but also enhances the applicability in various micro - motion exploration site environments.

[0019] 4. In the device for arranging a micro - motion detection array based on laser of the present invention, the leveling base further includes a plurality of leveling screws and a plurality of spirit levels. One end of the leveling screw is threadedly connected to the upper plate, and the other end of the leveling screw is fixedly connected to the lower plate. The spirit level is located on the upper surface of the upper plate. During application, the height of the upper plate is adjusted by rotating the leveling screw to adjust the height of the laser indicator. During the rotation process, at the same time, observe the position of the bubble in the spirit level on the upper surface of the upper plate until the bubbles in all spirit levels are stably located at the central position and then stop rotating, thereby ensuring that the laser indicator and the entire device are in a horizontal state. This structure makes the leveling operation more convenient and fast. Therefore, the present invention not only improves the applicability but also improves the convenience of operation.

[0020] 5. In the device for arranging a micro - motion detection array based on laser of the present invention, the bracket includes at least two sleeves sleeved with each other. The sleeves are slidably connected along the axial direction. One end of the bracket is snap - connected or threadedly connected to the tripod connector. During application, according to the actual arrangement requirements, adjust the relative positions of the sleeves in the bracket to adjust the overall height of the bracket to adapt to different terrains and arrangement requirements, increasing the versatility of the device. When storing, slide the sleeves to the shortest state, reducing the occupied space, facilitating carrying and storage, and enhancing the practicality and flexibility of the device. Therefore, the present invention not only improves the convenience of operation but also is convenient for storage and carrying. Description of the Drawings

If the angle measuring instrument 26 detects a deviation between the actual rotation angle and the expected angle, the indication control module 28 will adjust the vertical servo motor 24 or the horizontal servo motor 25 according to the feedback information and re - adjust the angle until the angle meets the requirements; the positioning laser 61 emitted by the laser generator 21 points to the preset position of the instrument 5 in the array, thus completing the layout of a single instrument 5. Repeat the above steps to layout all the instruments 5 in sequence, and finally complete the layout of the entire layout array 62.

[0080] Example 2: The basic content is the same as that of Embodiment 1, except that: a through laser ranging hole 231 is provided at the bottom of the support chassis 201; the laser rangefinder 23 is fixedly connected to the inner bottom of the support chassis 201; the laser emitted by the laser rangefinder 23 is emitted through the laser ranging hole 231.

[0081] During application, the laser rangefinder 23 is fixedly installed at the inner bottom of the support chassis 201, and the laser it emits is emitted through the laser ranging hole 231 at the bottom of the support chassis 201 for measuring the vertical height H between the laser indicator 2 and the ground. This not only ensures the firm connection between the laser rangefinder 23 and the support chassis 201, but also guarantees that the laser emitted by the laser rangefinder 23 can be measured without obstruction, thereby ensuring the accuracy and reliability of the measurement results.

[0082] Embodiment 3: The basic content is the same as that of Embodiment 1, except that: the support frame 202 is U-shaped; a bearing is installed in the middle of the top surface of the support chassis 201, the outer ring 204 of the bearing is fixedly connected to the support chassis 201, and the inner ring 205 of the bearing is fixedly connected to the bottom surface of the support frame 202.

[0083] During application, the inner ring 205 of the bearing in the middle of the top surface of the support chassis 201 provides stable support for the support frame 202, ensuring that the top surface of the support chassis 201 and the bottom surface of the support frame 202 are in the same horizontal plane. Since the laser generator 21 is located in the middle of the support frame 202, it also obtains stable support and levelness; when rotating in the horizontal direction, the horizontal servo motor 25 drives the support frame 202 to rotate, so that the laser generator 21 can rotate 360° in the horizontal direction; by adopting a bearing structure, the support frame 202 and the laser generator 21 can achieve flexible and stable horizontal rotation on the support chassis 201 while maintaining their movement accuracy in the pitching direction. This not only improves the stability of the device, but also enhances the flexibility and accuracy of the rotation.

[0084] Embodiment 4: The basic content is the same as that of Embodiment 1, except that: the support frame 202 includes two mutually parallel support side plates 203; the laser generator 21 is located in the groove between the two support side plates 203; the locator 22, the vertical servo motor 24, the angle measuring instrument 26, the indication communication module 27, and the indication control module 28 are respectively located inside the two support side plates 203 and are fixedly connected to the inside of the support side plates 203.

[0085] During application, the laser generator 21 is fixed through the groove between the two support side plates 203 to ensure its stability in the horizontal and vertical directions. The locator 22 integrated inside the support side plate 203 is used to collect the position information of the laser generator 21 in real time. The vertical servo motor 24 drives the laser generator 21 to make precise angular adjustments in the vertical direction. The angle measuring instrument 26 is used to detect the direction of the geomagnetic north pole and to feedback the pitch angle and horizontal angle data of the laser generator 21 in real time. The indication communication module 27 and the indication control module 28 are respectively responsible for communicating with the control terminal 1 and controlling the motion states of the vertical servo motor 24 and the horizontal servo motor 25. By integrating the locator 22, the vertical servo motor 24, the angle measuring instrument 26, the indication communication module 27 and the indication control module 28 inside the support side plate 203, not only the overall structural layout is optimized, the occupation of external space is reduced, but also the stability and reliability of the device are improved. At the same time, this design makes the connection between the modules more compact, reduces the signal transmission delay, and further improves the motion accuracy and control efficiency of the laser generator 21. In addition, the parallel design of the support side plate 203 provides a uniform supporting force for the laser generator 21 to ensure its stability during movement and avoid deviation problems caused by uneven force.

[0086] Embodiment 5: The basic content is the same as that of Embodiment 1, except that: the laser generator 21 includes a red light laser generator and a green light laser generator.

[0087] During application, according to the surrounding site environment during microseismic prospecting, the control terminal 1 is used to select to use the red light laser generator or the green light laser generator. For example, in a vegetated site, the green light laser generator can be selected to improve the visibility of the positioning laser 61. In a bare land without vegetation (generally tending to be red or brown) or an artificial site (mostly concrete and generally gray), the red light laser generator can be selected to adapt to the site environment. In addition, since the sunlight is strong during the day and it may be necessary to increase the brightness of the positioning laser 61, the laser brightness can be adjusted through the input module 11 of the control terminal 1, and the color of the laser generator can be switched to ensure that the indication of the positioning laser 61 is clearly visible, thereby improving the layout efficiency and accuracy.

[0088] Embodiment 6: The basic content is the same as that of Embodiment 1, except that: the bracket 4 includes at least two sleeves sleeved with each other, and the sleeves are slidably connected along the axial direction.

[0089] During application, the sleeve can be slid axially according to the actual layout requirements to adjust the relative positions of the sleeves in the bracket 4, thereby adjusting the overall height of the bracket 4 to adapt to different terrains and layout requirements. This height adjustment function increases the versatility and applicability of the device. At the same time, during storage, the sleeve can be slid to the shortest state, reducing the occupied space and facilitating carrying and storage, further enhancing the practicality and flexibility of the device.

[0091] During application, the support chassis 201 of the laser indicator 2 is passed through the annular bayonet 311 of the upper plate 31 and fixedly connected to the upper plate 31 (which can be snap or threaded connection) to ensure a stable and firm connection between the laser indicator 2 and the leveling base 3. At the same time, ensure that the laser emitted by the laser rangefinder 23 in the laser indicator 2 can pass through the laser ranging hole 231 and the laser emission hole 321 unobstructed and be perpendicular to the ground, so as to accurately measure the height and provide accurate information for subsequent layout to improve the layout accuracy.

[0093] During application, after fixedly connecting the upper plate 31 of the leveling base 3 to the laser indicator 2 and the lower plate 32 to the bracket 4, place the layout device on the ground in the micro motion detection area and ensure a stable connection between the bracket 4 and the ground. Then observe the position of the bubble in the spirit level 34 on the upper surface of the upper plate 31 and adjust the height of the upper plate 31 by rotating the leveling screw 33 until the bubbles in all spirit levels 34 are stably located at the central position and then stop rotating, so as to ensure that the laser indicator 2 and the entire layout device are in a horizontal state to improve the layout accuracy.

[0094] Embodiment 9: The basic content is the same as that of Embodiment 1, except that: several tripod connectors 35 are provided at the bottom of the lower layer plate 32; the number of the brackets 4 is the same as that of the tripod connectors 35; one end of the bracket 4 is connected to the tripod connector 35; one end of the bracket 4 is snap-connected or screwed to the tripod connector 35.

[0095] During application, one end of the bracket 4 is snap-connected or screwed to the tripod connector 35 at the bottom of the lower layer plate 32, so that the bracket 4 and the leveling base 3 maintain a stable connection relationship, thereby providing necessary stability for the device during the array layout process; when the array layout is completed, the bracket 4 is disassembled from the leveling base 3, and then the disassembled bracket 4 is folded or stored, which is convenient for carrying and storing; the snap or screw connection method not only makes the connection between the bracket 4 and the leveling base 3 more convenient and reliable, but also makes the disassembly process simple and fast, thereby improving the use efficiency and portability of the device.

[0096] Embodiment 10: The basic content is the same as that of Embodiment 1, except that: the bottom end of the bracket 4 is conical, and the material of the bottom end of the bracket 4 is stainless steel.
