Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically an elastic wave seismic hammer and an elastic wave detection system. Background Technology

[0002] TRT technology generates seismic waves based on the impact point triggered by hammering. When the seismic waves encounter acoustic impedance such as the interface of geological rock strata or the interface of discontinuous rock masses, part of the seismic wave signal is reflected back and received by sensors. The nature, location and scale of the geological body are then determined through tomographic imaging technology.

[0003] An investigation revealed a Chinese utility model patent (Publication No.: CN219201944U) disclosing an elastic wave seismic hammer and an elastic wave detection system. The system includes a hammerhead with a sensor and a lifting mechanism mounted on a base. A track above the base slides with the hammerhead. The elastic wave detection system comprises a base station, a main unit, and the aforementioned elastic wave seismic hammer. The sensor can wirelessly connect to a detector in a potential subsidence area, the detector is wirelessly connected to the base station, and the main unit is connected to the base station via a data cable. Replacing manual hammer swing with an elastic wave seismic hammer improves the stability of hammering energy, is convenient and labor-saving, and has high work efficiency. Using radio to transmit data to the base station avoids the risk of data transmission failure due to damaged data cables and the safety hazards caused by numerous lines. This utility model effectively solves the problem of inconsistent energy distribution and the laboriousness of manual hammer swinging, while also improving hammering accuracy.

[0004] Although the aforementioned patent uses a lever mechanism to control the hammer head for hammering via foot pedal, this method significantly reduces the stability of the vehicle during use. Consequently, the displacement of the vehicle during foot pedal operation causes a deviation in the hammer head's striking position, reducing hammering and detection accuracy. Furthermore, the hammer head's height adjustment range is limited by the lever mechanism, failing to further improve the convenience of detection at different heights.

[0005] Therefore, this utility model provides an elastic wave seismic hammer and an elastic wave detection system to solve the above problems. Utility Model Content

[0027] 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.

[0028] like Figure 1-4As shown, this utility model provides an elastic wave seismic hammer and an elastic wave detection system, including a platform 1, with casters 11 at the bottom of the platform 1, and a battery 3 and a column 4 fixedly connected to the upper surface of the platform 1; a positioning assembly 2, including a spring buffer 21, which is fixedly connected to the upper surface of the platform 1, and an operating station plate 22 is fixedly connected to the upper surface of the spring buffer 21, with a positioning pin 23 fixedly connected to the lower surface of the operating station plate 22, and the positioning pin 23 penetrating to the bottom of the platform 1; a guide support frame 41 is sleeved on the outside of the column 4, and a hammer head 4 is inserted into the other end of the guide support frame 41. 3. A traction rope 44 is connected to the top of the hammer head 43, and a sensor 46 is embedded in the outer wall of the hammer head 43. When in use, the device is moved to the operating point, and the operator stands above the operating station plate 22. At this time, the operating station plate 22 is pressed down, so that the bottom of the positioning pin 23 is inserted into the bottom surface, improving the overall stability of the device. Furthermore, the hammer head 43 can be moved upward by pulling the traction rope 44. When it is moved to the designated height, the traction rope 44 is released, and the hammer head 43 naturally strikes downward. The energy signal emitted by the hammer head 43 is received by the sensor 46 and transmitted to the base station. The base station transmits it to the host, thereby obtaining the desired data.

[0029] Furthermore, four sets of spring buffers 21 are provided, and the four sets of spring buffers 21 are respectively located at the four corners of the operating station plate 22. The upper and lower end lugs of the spring buffers 21 are respectively bolted to the operating station plate 22 and the vehicle plate 1. The elastic buffer support of the spring buffers 21 allows the positioning pins 23 to be stored above the ground in the normal state, ensuring the displacement of the device and satisfying the reset process after the operating station plate 22 is pressed down.

[0030] Furthermore, the bottom of the positioning pin 23 has a conical structure, and when the operating station plate 22 is under pressure, the lowest point of the positioning pin 23 is below the lowest point of the universal wheel 11. The conical structure of the bottom of the positioning pin 23 allows it to be better inserted into the ground, thereby improving the insertion and matching of the positioning pin 23 with the ground, which can improve the stability of the device in the operating state, and thus ensure the accuracy of the device's hammering.

[0031] Furthermore, the guide support frame 41 is fitted onto the outer wall of one end of the column 4 and has two threaded holes. Each threaded hole is threaded with a hand-tightening bolt 42. The hand-tightening bolt 42 abuts against the outer wall of the column 4. The outer wall of the column 4 is provided with scale lines. By adjusting the height of the guide support frame 41, the position of the hammer head 43 can be assisted in positioning, thereby facilitating flexible control of hammering detection at different heights. At the same time, the threaded connection of the hand-tightening bolt 42 ensures the stability of the guide support frame 41 after the vertical position is adjusted.

[0032] Furthermore, the outer wall of the positioning component 2 is also fixedly connected with four sets of guide wheels 45 via support rods. The guide wheels 45 are used for auxiliary guidance of the traction rope 44. A hand pull ring is provided at the end of the traction rope 44 away from the hammer head 43. The hand pull ring facilitates the traction of the traction rope 44. At the same time, the guide wheels 45 can ensure the auxiliary positioning and stability of the traction rope 44.

[0033] An elastic wave detection system includes a detector, a base station, a host computer, and the elastic wave seismic hammer. A sensor 46 on the hammer head 43 can be wirelessly connected to the detector placed in a potential collapse area. The detector is wirelessly connected to the base station, and the host computer is connected to the base station via a data cable.

[0034] Working principle: First, the site is set up, and the hammering point and detector placement point are determined. Then, the vehicle platform 1 is pushed to the hammering point. After aligning the hammer head 43 with the hammering point, the hammering height of the hammer head 43 is adjusted. Then, the operator stands on the operating platform 22 to perform the test. By pulling the traction rope 44, the hammer head 43 is moved to the designated height. Then, under the natural downward hammering of the hammer head 43, the sensor 46 transmits the received hammering energy information to the base station via wireless signal. The detector transmits the received elastic wave and elastic wave reflection information to the base station via wireless signal. The base station transmits the data to the host. The host processes the data transmitted from the base station through the data processing system to determine the geological conditions of the potential subsidence area.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
