[0043] In geophysical exploration, the source device is a key device for generating seismic waves, which are used for the detection and imaging of underground structures. Currently, widely used source devices include explosive sources, drop-weight hammer sources, and air gun sources. Among them, the source signal generated by the explosive source is strong, the air gun source has a wide frequency range and low environmental impact, and the acceleration hammer source reduces the mass of the drop-weight source while reducing its lifting height. It increases its excitation speed through driving methods such as strong coil springs, hydraulics, or air pressure to ensure the excitation energy. However, the excitation angles of various source devices are single, and they can only excite shear waves or longitudinal waves, which has certain limitations in use.

[0044] In view of this, the present invention provides an acceleration impact source device 100, Figures 1 to 11 This is an embodiment of the acceleration impact source device 100 provided by the present invention.

[0045] See also Figures 1 to 8The acceleration impact source device 100 includes a frame 1, an anvil 2, a heavy hammer 3 and a lifting and releasing mechanism 4. The frame 1 is extended along the first direction and has a first end 11 and a second end 12. The first end 11 is used to connect with an external carrier, and the second end 12 is provided with a through hole; the anvil 2 is provided at the second end 12 and is movably connected to the frame 1 so that the frame 1 can move relative to the anvil 2 around an axis extending along the second direction; the heavy hammer 3 is provided in the frame 1 and extends along the first direction, and its impact end can move relative to the frame 1 through the through hole along the first direction between a charging position and an impact position, the charging position is provided in the frame 1 and close to the first end 11, and the impact position is provided at the anvil 2; the lifting and releasing mechanism 4 includes an elastic member 41 , a first lifting member 42, a second lifting member 43 and a releasing member 44, the elastic member 41 is arranged in the frame 1, and is connected to the first end 11, and is extended along the first direction, the first lifting member 42 is arranged on the heavy hammer 3, the second lifting member 43 is arranged on the frame 1, and is driven and connected to the first lifting member 42, for driving the first lifting member 42 to drive the heavy hammer 3 to move toward the charged position, so that the heavy hammer 3 acts on the elastic member 41 to generate an elastic force, the releasing member 44 is arranged on the frame 1, for acting on the first lifting member 42 to separate from the second lifting member 43 when the heavy hammer 3 moves to the charged position, so that the heavy hammer 3 is moved to the impact position by the elastic force and impacts the anvil 2; wherein, the first direction and the second direction are perpendicular to each other in the plane.

[0046] In the technical solution of the present invention, the anvil 2 obtains acceleration through the lifting and releasing mechanism 4 to impact the anvil 2 for exploration, and the anvil 2 is movably connected to the frame 1, so that the frame 1 can rotate relative to the anvil 2, that is, the angle of the frame 1 and the anvil 2 is adjustable. In this way, the acceleration impact source device 100 can excite energy at multiple angles, and can excite both shear waves and longitudinal waves, thereby meeting more exploration conditions, being suitable for more exploration scenarios, and greatly improving practicality.

[0047] Please note that Figures 1 to 4 In one embodiment of the present invention, the frame 1 is configured in a hollow cylindrical shape. More specifically, the frame 1 and the weight 3 are concentrically configured.

[0048] It should also be noted that, in the present invention, the form of the external carrier is not limited and can be an excavator, for example. More specifically, in one embodiment of the present invention, the first end 11 is provided with a clamping plate, which is detachably connected to the external carrier via the clamping plate. Furthermore, the clamping plate with different mounting holes can be used to enable assembly of the frame 1 with different external carriers, improving flexibility and practicality.

[0049] Further, see Figure 1 and Figure 5 The anvil 2 has a sidewall 21 extending along a third direction through the anvil 2, with its inner wall matching the outer wall of the frame 1, so that the frame 1 can rotate to a degree greater than 0° and less than or equal to 180°. The first, second, and third directions are perpendicular to each other within a plane. By providing the sidewall 21, the frame 1 is prevented from interfering with other components, such as the anvil 2, during rotation, allowing the acceleration impact source device 100 to generate energy at a wider range of angles.

[0050] Furthermore, based on the above-mentioned embodiment of "the frame 1 is configured in a hollow cylindrical shape", the inner peripheral wall of the avoidance groove 21 is configured in an arc surface.

[0051] For details, please refer to Figures 1 to 4 ,as well as Figure 8 The first lifting member 42 is inserted into the heavy hammer 3 and the frame 1 along the second direction, and includes a fixing part 421, an elastic part 422 and a lifting part 423 connected in sequence along the second direction. The fixing part 421 is fixedly connected to the heavy hammer 3, and the lifting part 423 can move relative to the heavy hammer 3 along the second direction through the elastic part 422; the second lifting member 43 is arranged on one side of the frame 1 in the second direction, and is arranged close to the lifting part 423, and is driven and connected to the lifting part 423 to drive the lifting part 423 to drive the heavy hammer 3 to move toward the charged position; the release member 44 is located in the second direction. The first lifting member 42 and the second lifting member 43 are separated, and the heavy hammer 3 moves to the charged position.

[0052] In this way, the first lifting member 42 drives the weight 3 to move toward the elastic member 41 through the second lifting member 43, thereby achieving the lifting of the weight 3 (such as Figure 10As shown), and in this process, the first lifting member 42 acts on the elastic portion 422, so that the elastic portion 422 changes from the initial state to the compressed state, generating elastic force for energy storage; and when the heavy hammer 3 is close to the stored energy position, the lifting portion 423 compresses the elastic portion 422 under the action of the release member 44 and moves away from the second lifting member 43, until the heavy hammer 3 moves to the energy storage position, and the lifting portion 423 is separated from the second lifting member 43 (as shown). Figure 11 As shown), the second lifting member 43 removes the force from the weight 3, and the weight 3 is only subjected to the elastic force of the elastic member 41, and hits the anvil 2 with a large acceleration, thereby releasing the weight 3, thereby stimulating seismic waves with a deeper detection depth and higher resolution for exploration.

[0053] It should be noted that, in the present invention, the configuration form of the elastic portion 422 is not limited, and it can be a rubber strip, a coil spring, etc.

[0054] Further, see Figure 1 、 Figure 4 、 Figure 7 and Figure 8 The first abutting end 4231 of the lifting portion 423 is wedge-shaped and away from the fixing portion; the releasing member 44 is located on the side of the first lifting member 42 facing the first end 11, and its second abutting end 441 facing the second end 12 is wedge-shaped, so as to abut against the first abutting end 4231 when the heavy hammer 3 is adjacent to the charged position, thereby causing the lifting portion 423 to move away from the second lifting member 43.

[0055] In this way, the release of the heavy hammer 3 is automatically completed by the relative sliding of the wedge surface of the release member 44 and the wedge surface of the lifting part 423, without the need for an additional power source. During the release of the heavy hammer 3, the lifting part 423 moves away from the release member 44 until it is separated from the release member 44, and then it automatically resets itself under the elastic force of the elastic part 422. The structure is simple and the operation is stable.

[0056] Further, see Figure 1 The lifting release mechanism 4 also includes a lifting stop block 45, and the second lifting member 43 is driven and connected to the lifting stop block 45 to drive the lifting stop block 45 to abut against a side of the lifting portion 423 toward the second end 12, and drive the lifting portion 423 to move in a direction close to the first end 11.

[0057] Furthermore, in an embodiment of the present invention, the second lifting member 43 is a hydraulic cylinder. The hydraulic cylinder has a driving shaft extending along the first direction. The driving shaft is drivingly connected to the lifting stop block 45 .

[0058] Thus, the working process of the acceleration impact source device 100 is as follows: first, determine the angle between the frame 1 and the anvil 2, and drive the frame 1 to rotate; then, drive the lifting stop block 45 to move toward the second end 12 through the hydraulic cylinder until the lifting stop block 45 moves to the lower side of the lifting portion 423 (such as Figure 9 Then, the hydraulic cylinder drives the lifting stop block 45 to drive the lifting portion 423 to move toward the first end 11, thereby driving the heavy hammer 3 to move. At this time, the heavy hammer 3 also gradually compresses the elastic member 41; wait until the lifting portion 423 abuts against the release member 44 (as shown); Figure 10 As shown), the lifting portion 423 moves toward the first end 11, and at the same time, under the action of the release member 44, it moves away from the lifting stop block 45 and compresses the elastic portion 422 until the lifting portion 423 is separated from the lifting stop block 45, and the heavy hammer 3 is located in the potential storage position (as shown). Figure 11 As shown), and under the elastic force of the elastic member 41, it hits the anvil 2 with a large acceleration. At the same time, during the release process of the heavy hammer 3, the lifting portion 423 moves away from the release member 44 until separation, and the lifting portion 423 automatically resets under the elastic force of the elastic portion 422.

[0059] It should be noted that, in the present invention, the second lifting member 43 may also be a driving motor, a cylinder, etc.

[0060] For details, please refer to Figure 1 、 Figure 4 and Figure 7 The lifting and releasing mechanism 4 further includes a first fixing ring 46, which is sleeved around the outer periphery of the frame 1 and detachably connected to the frame 1. The releasing member 44 is fixedly mounted on the first fixing ring 46, and its second stop end protrudes relative to the first fixing ring 46 in a direction toward the second end 12. In this manner, the releasing member 44 is mounted on the frame 1 via the first fixing ring 46.

[0061] It should be noted that the detachable connection method between the first fixing ring 46 and the frame 1 is not limited, and can be a threaded connection, a snap connection, etc.

[0062] For further information, see Figure 1The lifting and releasing mechanism 4 further includes a second fixing ring 47, which is detachably mounted on the frame 1 and spaced apart from the first fixing ring 46 along the first direction. The second fixing ring 47 is used to securely mount the second lifting member 43 together with the first fixing ring 46. This prevents the second lifting member 43 from being subjected to an outward torque and twisting outward during the lifting of the weight 3.

[0063] For details, please refer to Figures 2 to 4 The frame 1 is penetrated by a movable hole 13 along the second direction, and the movable hole 13 is extended along the first direction, so that the first lifting member 42 can extend out of the frame 1 and be subjected to the force of the second lifting member 43 and the release member 44. In this way, the frame 1 is prevented from affecting the movement of the first lifting member 42.

[0064] Specifically, the elastic member 41 is coaxially arranged with the weight 3, so as to ensure that the weight 3 is subjected to uniform force.

[0065] For details, please refer to Figure 6 In one embodiment of the present invention, the elastic member 41 is a nitrogen spring. As such, the nitrogen spring has the advantages of being small in size, generating a large elastic force, being stable in operation, and having a long service life, and can generate a large acceleration on the weight 3.

[0066] Furthermore, the lift-release mechanism 4 also includes a booster pump connected to the nitrogen spring. This allows the inflation pressure of the nitrogen spring to be adjusted by regulating the booster pump. Different inflation pressures of the nitrogen spring result in different initial and final spring forces, thereby varying the acceleration of the weight 3 when it strikes the anvil 2, thereby meeting different exploration requirements.

[0067] Specifically, in the present invention, the rotatable connection between the anvil 2 and the frame 1 is not limited, and can be a pivot connection, a threaded connection, etc. For more details, please refer to Figure 1 In one embodiment of the present invention, the outer wall of the frame 1 is provided with two mounting columns 5 symmetrically arranged along the second direction, and each of the mounting columns 5 extends along the second direction; the acceleration impact type seismic source device 100 also includes a connecting component 6, and the connecting component 6 includes two inner plates 61 symmetrically arranged along the frame 1 and two outer plates 62 symmetrically arranged along the frame 1, the two inner plates 61 are arranged between the two outer plates 62, and the inner plates 61 and the outer plates 62 arranged on the same side are both connected to the mounting columns 5 on the same side, and are both connected to the anvil 2, so as to realize the connection between the frame 1 and the anvil 2.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
