This device allows the location of excitation points (simulating field shot points) and receiving points (simulating field receiver points) at arbitrary positions within three-dimensional space within the laboratory. This allows for the simulation of positioning and acquisition at various shot and receiver locations during field seismic exploration.

[0003] A Chinese invention patent, application publication number CN113311475A, discloses a three-dimensional seismic physical simulation positioning and acquisition device, including a frame, two sets of three-dimensional positioning components, an excitation probe, a receiving probe, and a control system.

For example, when the two positioning and acquisition devices are moving, since the excitation probe and the receiving probe are moving in three-dimensional coordinates, if the coordinate movement is wrong, it may also cause a vertical collision between the two positioning devices. However, the existing technology is not convenient for safety protection against vertical collisions. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a three-dimensional seismic physical simulation positioning and acquisition device, including a simulation positioning and acquisition device and a controller, wherein the simulation positioning and acquisition device includes two connecting beams 101 and two movable telescopic rods 102, the bottoms of the two movable telescopic rods 102 are respectively connected to an excitation probe and a receiving probe, and also includes a frame and two groups of three-dimensional positioning components (not shown in the figure), the two groups of three-dimensional positioning components are both arranged on the frame, the two groups of three-dimensional positioning components can respectively move back and forth along a first direction, the movable telescopic rod 102 can move back and forth along a second direction on the corresponding movable base, and the movable telescopic rod 102 can be extended and retracted along a third direction, the first direction, the second direction and the third direction are not parallel to each other, and finally the excitation probe and the receiving probe are moved in three-dimensional space. The above is the existing technology, and the details can be referred to the existing published patent (application publication number CN113311475A, a three-dimensional seismic physical simulation positioning and acquisition device).

[0027] A rotating disk 2 is rotatably connected to the telescopic end of the movable telescopic rod 102 , a fixed block 3 is fixed on the retracting rod of the movable telescopic rod 102 , and an axial collision protection unit is provided on the side of the rotating disk 2 and the fixed block 3 .

[0028] like Figure 2As shown, the axial collision protection unit includes a first touch unit 401 and a second touch unit 402. The first touch unit 401 and the second touch unit 402 are in contact with each other. When rotation occurs between the rotating disk 2 and the fixed block 3, the first touch unit 401 and the second touch unit 402 are out of contact. At this time, the controller controls the two groups of three-dimensional positioning components to stop running, and the staff inspects the first touch unit 401 and the second touch unit 402. After the inspection is completed, the first touch unit 401 and the second touch unit 402 are reset.

[0029] A vertical groove is provided on the side of the support block 5, and an insertion shaft 601 is fixed in the vertical groove. A mounting block 7 is movably connected to the shaft body of the insertion shaft 601. The first touch unit 401 or the second touch unit 402 is installed in the front of the mounting block 7. In order to improve the structural stability of the mounting block 7, the mounting block 7 is configured as a triangular block, and a spring 602 is fixed between the mounting block 7 and the groove wall of the vertical groove. In order to improve the vertical stability of the mounting block 7, two springs 602 are provided, which are respectively located at the top and bottom of the mounting block 7. The setting of the vertical groove and the spring 602 can achieve buffering of the first touch unit 401 or the second touch unit 402 after a vertical collision, thereby further increasing the protection performance of the device.

[0030] A vertical collision protection unit 8 is provided on the side of the rotating disk 2 facing the mounting block 7 .

[0031] like Figure 2 and Figure 3 As shown, the vertical collision protection unit 8 includes a socket 801, in which an insertion rod 802 is inserted, and a contact piece and an indicator piece are respectively provided at the bottom and top of the insertion rod 802.

[0032] Among them, the indicator includes a top conductive rod 803 and a bottom conductive rod 805, and the ends of the top conductive rod 803 and the bottom conductive rod 805 are respectively fixed with a resistor block 804 and a conductive block 806. To ensure the connection stability of the resistor block 804, the side of the resistor block 804 is fixed to the side wall of the socket 801, and the other end of the bottom conductive rod 805 is fixed to the plug rod 802. The resistor block 804 and the conductive block 806 are in contact, and the bottom conductive rod 805 can drive the conductive block 806 to move along the side of the resistor block 804. During the movement, the resistor block 804 and the conductive block 806 always maintain a contact state. In addition, it should be noted that the conductive block 806 is located in the middle position of the resistor block 804, and the top conductive rod 803 and the bottom conductive rod 805 are respectively connected by wires, and the power supply and indicator are connected to the wires. The indicator is electrically connected to the controller.

[0033] The indicator may be a current indicator or a voltage indicator. When the conductive block 806 moves along the side of the resistor block 804, the resistance in the circuit changes, thereby causing the current value in the current indicator or the voltage value in the voltage indicator to change.

[0034] Among them, the contact part includes a rolling ball 807 and a bottom limit plate 808. The rolling ball 807 is movably set in the bottom limit plate 808. A top rod 809 is fixed at the bottom end of the insertion rod 802, and the top rod 809 is in contact with the top of the rolling ball 807. In order to reduce the friction between the rolling ball 807 and the top rod 809 and the bottom limit plate 808, and facilitate the rolling of the rolling ball 807, in this solution, the rolling ball 807 is a metal ball.

[0035] To supplement this solution, when the excitation probe or the receiving probe connected to the front of the two mounting blocks 7 rotates sideways, the mounting block 7 drives the support block 5 to rotate along the bottom of the rotating disk 2. At this time, the first touch unit 401 and the second touch unit 402 are out of contact. At this time, the controller controls the two sets of three-dimensional positioning components to stop running, thereby achieving protection against lateral collision.

[0036] When the excitation probe or the receiving probe connected to the front of the two mounting blocks 7 collides vertically, the collision force drives the mounting block 7 to move upward or downward, and the spring 602 buffers the vertical collision force, thereby protecting the excitation probe or the receiving probe. At the same time, when the mounting block 7 moves upward or downward, since the gravity of the rolling ball 807 is small, the rolling ball 807 is always in contact with the top of the mounting block 7. At this time, the mounting block 7 drives the rolling ball 807 to move up and down, and the conductive block 806 moves along the side of the resistance block 804. Since the resistance value in the circuit changes, the current or voltage value of the indicator changes. When the controller detects the change value, the controller controls the two sets of three-dimensional positioning components to stop running, thereby achieving protection against vertical collision.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
