Description

Technical Field

[0001] This utility model relates to the field of exploration equipment technology, and in particular to an exploration equipment based on the three-dimensional seismic method. Background Technology

[0002] A geophone is a specialized sensor used in geological exploration and engineering surveying. It is a sensor that converts vibration into an electrical signal. When a corresponding vibration signal is transmitted to the geophone, the coil of the geophone core moves relative to the magnetic system, cutting the magnetic lines of force. At this time, an electrical signal is induced at both ends of the coil, thus converting the vibration signal into an electrical signal.

[0003] Exploration equipment based on the three-dimensional seismic method mainly includes source equipment, detection equipment, data acquisition equipment, and data processing equipment.

[0004] Explosive seismic source: By loading explosives into a blast hole at a certain depth underground, the explosives are detonated to generate seismic waves.

[0005] Moving-coil detector: Based on the principle of electromagnetic induction, when a seismic wave causes the coil to move in a magnetic field, an induced electromotive force is generated, thereby converting the ground vibration signal into an electrical signal.

[0006] Seismic data acquisition station: It is the core equipment for acquiring 3D seismic exploration data, used to acquire, record and store seismic signals received by the detector.

[0007] Traditional geophone plug installation methods are often quite simple, directly inserting the entire geophone into the ground without effective reinforcement and support structures. In soft geological conditions, this can easily lead to loosening or instability, affecting the accuracy of data acquisition. Moreover, when measuring on surfaces with high surface hardness, improper operation often results in direct impacts on the geophone body, causing damage to the equipment, shortening its service life, and increasing exploration costs. Utility Model Content

[0008] Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this invention provides an exploration device based on the three-dimensional seismic method. It solves the problem that traditional geophone plug installation methods are often too simple, directly inserting the entire geophone into the ground without effective reinforcement and support structures. In soft geological conditions, this can easily lead to loosening or instability, affecting the accuracy of data acquisition. Moreover, when measuring on surfaces with high surface hardness, improper operation often results in direct impacts to the geophone body, causing damage to the equipment, shortening its service life, and increasing exploration costs.

[0010] Technical solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] An exploration device based on the three-dimensional seismic method includes a detector body. The lower end of the detector body is provided with a detector plug for exploration. A pressure baffle is fixedly installed through the detector plug. The pressure baffle is provided with a protective sleeve for impact. A fixed circular plate is slidably installed through the lower end of the detector plug. The lower end of the fixed circular plate is provided with a reinforcing support rod for reinforcement.

[0013] Preferably, the detector body has a mounting groove at its lower end, the detector plug is threaded into the mounting groove in the detector body, the pressure baffle has four limiting holes, and the protective sleeve has four limiting blocks fixedly installed at its lower end.

[0014] Preferably, the four limiting blocks at the lower end of the protective sleeve are slidably installed through the four limiting holes opened in the pressure baffle, the fixed circular plate is attached to the lower end of the pressure baffle, and the number of the reinforcing supports is four, which are fixedly installed at equal intervals around the lower end of the fixed circular plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The four reinforcing rods in this new design provide additional support for the geophone plug when it is inserted into the ground. When encountering hard soil or complex geological environments, the geophone plug may be difficult to insert and secure directly. The reinforcing rods are equidistantly distributed around the lower end of the fixed circular plate, and enter the ground along with the geophone plug, providing support from multiple directions. This ensures the geophone plug is more firmly fixed in the soil, guaranteeing the stability of the exploration equipment during operation and improving the accuracy of the survey data.

[0017] Second, this utility model separates the detector plug from the detector body and sets a protective sleeve on the detector plug. During installation, the detector plug is first separated from the body, and the detector plug is inserted into the object under test by tapping the protective sleeve. This avoids directly hitting the detector body, reduces the risk of damage to the equipment, extends the service life of the equipment, and reduces exploration costs. Attached Figure Description

[0024] This application provides an exploration device based on the three-dimensional seismic method, which effectively solves the technical problems of traditional geophone plug installation methods, which are often relatively simple, directly inserting the geophone into the ground without effective reinforcement and support structures. In soft geological conditions, the geophone is prone to loosening or instability, affecting the accuracy of data acquisition. Moreover, when measuring on the hard surface of the object being measured, improper operation often results in direct impact on the geophone body, which can easily damage the equipment, shorten its service life, and increase exploration costs.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application aims to effectively address the problems of traditional detector plug installation methods, which are often quite simple, directly inserting the detector into the ground without effective reinforcement and support structures. This can easily lead to loosening or instability in soft geological conditions, affecting the accuracy of data acquisition. Furthermore, when measuring on surfaces with high surface hardness, improper operation often results in direct impacts to the detector body, causing damage to the equipment, shortening its lifespan, and increasing exploration costs. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an advanced exploration device based on the three-dimensional seismic method. Its core components include a detector body 11. At the lower end of the detector body 11, a detector plug 13 for key exploration work is provided. A pressure baffle 24 is installed through and fixedly mounted on the detector plug 13. A protective sleeve 21 for impact protection is provided on the pressure baffle 24. A fixed circular plate 25 is slidably mounted through the lower end of the detector plug 13. A reinforcing support rod 26 for reinforcement is provided at the lower end of the fixed circular plate 25.

[0028] The detector body 11 has a mounting groove 12 at its lower end. The detector plug 13 is securely installed in the mounting groove 12 of the detector body 11 by a precise threaded installation method. Four limiting holes 23 are opened through the pressure baffle 24. At the same time, four limiting blocks 22 are fixedly installed at the lower end of the protective sleeve 21. The four limiting blocks 22 at the lower end of the protective sleeve 21 are precisely slidably installed through the four limiting holes 23 opened in the pressure baffle 24, ensuring the stability of the structure and the accuracy of the operation.

[0029] The fixed circular plate 25 is tightly fitted to the lower end of the pressure baffle 24, providing reliable support for the entire device. Four reinforcing support rods 26 are used to reinforce the support and are firmly fixed to the lower end of the fixed circular plate 25 in a circumferentially equidistant manner, providing solid protection for the entire equipment during the exploration process.

[0030] Working principle:

[0031] First, when using the device, the detector plug 13 is first removed from the lower end of the detector body 11. Then, the fixing plate 25 is passed through the lower end of the detector plug 13 and fitted to the lower end of the pressure baffle 24. The protective sleeve 21 is inserted into the four limiting holes 23 opened in the pressure baffle 24 through the four limiting blocks 22. At this time, the lower end of the detector plug 13 is facing the ground. Then, the upper end of the protective sleeve 21 can be tapped with a tool. At this time, the detector plug 13 can be inserted into the ground under the tapping. At the same time, since the lower end of the pressure baffle 24 will drive the fixing plate 25 and the four reinforcing rods 26 to move down together, the four reinforcing rods 26 will also be inserted into the ground. At this time, the detector plug 13 is installed in the ground. The four reinforcing rods 26 in this new type can provide additional support for the detector plug 13 when it is inserted into the ground. When encountering hard soil or complex geological environments, the geophone plug 13 may be difficult to insert and fix directly. The reinforcing support rod 26 is circumferentially distributed at the lower end of the fixed circular plate 25. It enters the ground together with the geophone plug 13 and provides support from multiple directions, so that the geophone plug 13 is more firmly fixed in the soil, ensuring the stability of the exploration equipment during operation and improving the accuracy of the survey data.

[0032] The second step is to connect the detector body 11 to the detector plug 13 during use. The detector body 11 and the detector plug 13 are connected by contacts, so that the signal received by the detector plug 13 can be transmitted to the detector body 11. This utility model designs the detector plug 13 and the detector body 11 separately and provides a protective sleeve 21 on the detector plug 13. During installation, the detector plug 13 is first separated from the body, and the detector plug 13 is inserted into the object under test by tapping the protective sleeve 21. This avoids directly hitting the detector body 11, reduces the risk of damage to the equipment, extends the service life of the equipment, and reduces exploration costs.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
