Description

Technical Field

[0001] This utility model relates to the field of shallow seismic exploration technology, specifically to a shallow seismic exploration source instrument. Background Technology

[0002] Shallow seismic exploration is a geophysical exploration method that uses artificially generated seismic waves to analyze their propagation patterns within 500 meters of the earth's surface, thereby inferring geological information such as stratigraphic structure, lithology, faults, or underground cavities. It is widely used in engineering geology, mineral resources, hydrological surveys, archaeology, and other fields. When using a seismic source instrument, seismic waves encounter different lithological strata; some energy is reflected back to the surface, while some is refracted or transmitted. Subsequently, a geophone array records the seismic wave signals, and parameters such as wave velocity, amplitude, and travel time are analyzed to infer the underground structure.

[0003] Chinese patent publication number CN209296937U discloses a mechanical seismic source excitation device for shallow seismic exploration. The device includes: a support frame comprising several support rods and a load-bearing platform, with one end of each support rod connected to the load-bearing platform and the other end fixed to the ground; a fixed pulley, fixedly installed on the ground side of the load-bearing platform, with a steel wire rope mounted on the pulley; an electric hoist located at the lower part of the support frame and connected to one end of the steel wire rope; and a counterweight connected to the other end of the steel wire rope via an automatic release device. A connection and control switch are provided, which are connected to the electric hoist and control the operation of the electric hoist. As a further improvement of this utility model, the automatic unhooking device includes a fixed part and a suspension part. The fixed part is located between the two layers of the suspension part. The upper end of the fixed part is provided with a fixing hole, and the lower end of the fixed part is provided with a groove. The suspension part is bolted to the middle of the fixed part. One end of the suspension part is connected to a handle, and the other end of the suspension part is provided with a hook body that matches the lower part of the fixed part. The lower part of the fixed part is placed in the hook body of the suspension part.

[0004] The aforementioned utility model uses an electric hoist to pull a steel wire rope, and a counterweight is connected to the steel wire rope through an automatic unhooking device. When vibration is triggered, the automatic unhooking device is manually triggered to achieve the unhooking action of the counterweight. However, after unhooking, the steel wire rope and the unhooking structure need to be reconnected, resulting in low working efficiency when the seismic source needs to be continuously triggered. At the same time, the falling counterweight lacks a limiting structure and will roll freely after falling to the ground, posing a certain safety hazard. Therefore, we propose a shallow seismic exploration source instrument. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a shallow seismic exploration source instrument, comprising an electric hoist traction mechanism, a lifting rope, a rotating docking mechanism, a support frame, a fixed pulley, and a counterweight. The output end of the electric hoist traction mechanism is fixedly connected to one end of the lifting rope, which is wound around the fixed pulley. The fixed pulley is fixed to the support frame, and the other end of the lifting rope is fixed to the rotating docking mechanism, which is equipped with a counterweight.

[0006] In some embodiments, the rotary docking mechanism comprises a support cylinder, a first slide rail, a mounting frame, a docking motor, a sliding bracket, a connecting chuck, a locking block, a limiting block, and a second slide rail. The support cylinder has a first slide rail symmetrically arranged in the upper part, and a sliding bracket is slidably connected in the first slide rail.

[0007] In some embodiments, the sliding bracket is fixed to both sides of the mounting frame, and the mounting frame is fixedly connected to the lifting rope.

[0008] In some embodiments, a docking motor is fixedly installed in the mounting bracket, and the output end of the docking motor passes through the mounting bracket and is fixed to the top of the connecting chuck.

[0009] In some embodiments, the limiting blocks are symmetrically mounted on the counterweight, and the limiting blocks are slidably connected in the second slide rail, which is formed on the support cylinder.

[0010] In some embodiments, a locking block is provided on the top of the counterweight, and the locking block engages with the connecting chuck.

[0011] This utility model has at least the following beneficial effects:

[0012] This invention uses a vertically arranged support cylinder to slide and connect a weight. Limiting blocks installed on both sides of the weight slide in a second track to prevent the locking block from rotating when it falls. When a vibration source needs to be generated, the electric hoist traction mechanism releases the lifting rope. The two sides of the mounting frame move down along the first track under the limitation of the sliding bracket, and the connecting chuck is fitted into the slot at the top of the locking block. Then, the docking motor drives the connecting chuck to rotate and fix the locking block and the connecting chuck in the vertical direction. Then, the electric hoist traction mechanism drives the weight to rise. Finally, the docking motor drives the connecting chuck to flip and release the locking block and the connecting chuck in the vertical direction, so that the weight falls and generates a vibration source. The docking and disconnection of the weight and the lifting rope can be completed automatically without manual intervention. The working efficiency is high when continuously triggering the vibration source. At the same time, the weight slides under the limitation of the support cylinder, which prevents the weight from rolling freely after falling and eliminates safety hazards.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-3 This utility model provides a technical solution: a shallow seismic exploration source instrument, including an electric hoist traction mechanism 1, a lifting rope 2, a rotating docking mechanism 3, a support frame 4, a fixed pulley 5, and a counterweight 6. The output end of the electric hoist traction mechanism 1 is fixedly connected to one end of the lifting rope 2, the lifting rope 2 is wound around the fixed pulley 5, the fixed pulley 5 is fixed to the support frame 4, and the other end of the lifting rope 2 is fixed to the rotating docking mechanism 3. The rotating docking mechanism 3 is equipped with a counterweight 6. The electric hoist traction mechanism 1 realizes the raising and lowering of the rotating docking mechanism 3 by winding the lifting rope 2 with a motor. The fixed pulley 5 connected to the support frame 4 is used to adjust the tension direction of the lifting rope 2, and at the same time fixes the entire device on the ground.

[0021] The rotating docking mechanism 3 consists of a support cylinder 31, a first slide rail 32, a mounting frame 33, a docking motor 34, a sliding bracket 35, a connecting chuck 36, a locking block 37, a limiting block 38, and a second slide rail 39. The support cylinder 31 has a first slide rail 32 symmetrically opened in the upper part. The sliding bracket 35 is slidably connected in the first slide rail 32. When in use, the support cylinder 31 is first fixed on the ground, and the axis of one end of the lifting rope 2 passing through the fixed pulley 5 is made to coincide with the axis of the support cylinder 31, thereby reducing the frictional consumption of the entire lifting structure.

[0022] The sliding bracket 35 is fixed on both sides of the mounting frame 33, which is fixedly connected to the lifting rope 2. A docking motor 34 is fixedly installed in the mounting frame 33, and the output end of the docking motor 34 passes through the mounting frame 33 and is fixed to the top of the connecting chuck 36. Limiting blocks 38 are symmetrically installed on the hammer 6 and are slidably connected in the second slide rail 39, which is located on the support cylinder 31. A locking block 37 is provided on the top of the hammer 6 and engages with the connecting chuck 36. The hammer 6 is slidably connected by the vertically arranged support cylinder 31. The limiting blocks 38 installed on both sides of the hammer 6 are slidably connected in the second slide rail 39 to prevent the locking blocks 37 from rotating when falling. When the vibration source needs to be activated, the electric hoist traction mechanism 1 releases the lifting rope. 2. Under the limitation of the sliding bracket 35, the two sides of the mounting frame 33 move down along the first slide rail 32, and the connecting chuck 36 is sleeved in the slot at the top of the locking block 37. Then, the docking motor 34 drives the connecting chuck 36 to rotate in the vertical direction to fix the locking block 37 and the connecting chuck 36. Then, in conjunction with the electric hoist traction mechanism 1, the hammer 6 is driven to rise. Finally, in conjunction with the docking motor 34, the connecting chuck 36 is rotated to release the locking block 37 and the connecting chuck 36 in the vertical direction, so that the hammer 6 falls and generates a vibration source. The docking and disengagement of the hammer 6 and the lifting rope 2 can be completed automatically without manual intervention. The working efficiency is high when the vibration source is continuously triggered. At the same time, the hammer 6 slides under the limitation of the support cylinder 31 to prevent the hammer 6 from rolling freely after falling.

[0023] Example 2:

[0024] Please see Figure 4This utility model provides a technical solution: a shallow seismic exploration source instrument, including an electric hoist traction mechanism 1, a lifting rope 2, a rotating docking mechanism 3, a support frame 4, a fixed pulley 5, a counterweight 6, and an auxiliary support mechanism 100. The output end of the electric hoist traction mechanism 1 is fixedly connected to one end of the lifting rope 2, the lifting rope 2 is wound around the fixed pulley 5, the fixed pulley 5 is fixed to the support frame 4, and the other end of the lifting rope 2 is fixed to the rotating docking mechanism 3, in which the counterweight 6 is provided; based on the first embodiment, an auxiliary support mechanism 100 is added, the auxiliary support mechanism 100 consisting of a support ring 101, a connecting seat 102, a screw 103, and a base. The device consists of a support 104, with a support ring 101 fixed to the support cylinder 31. A connecting seat 102 is symmetrically arranged on the support ring 101, and a screw 103 is threadedly connected to the connecting seat 102. A bottom support 104 is provided at the bottom end of the screw 103. The connecting seat 102 is supported by the support ring 101, which is sleeved and fixed on the support cylinder 31. Rotating the screw 103 can drive the bottom support 104 at the bottom of the screw 103 to move downward. During the operation of the exploration seismic source instrument, the bottom support 104 provides bottom supports at the four corners of the entire device, maintains the verticality of the support cylinder 31, and thus reduces the friction generated during the descent of the weight 6.
