Description

Technical Field

[0001] This utility model relates to the field of geophysical exploration technology, and in particular to a small-tonnage self-propelled controllable seismic source capable of achieving dual-wave vibration. Background Technology

[0002] Seismic exploration plays a crucial role in geophysics as a key means of analyzing geological structures, determining geological formations, and exploring resources such as oil, gas, and coal. Based on the propagation mode of the excited elastic waves, controllable seismic sources can be divided into two categories: P-wave controlled sources and S-wave controlled sources. P-wave exploration, as a conventional exploration method, occupies an important position in seismic exploration work. The main purpose of P-wave exploration used by seismic bureaus is to investigate the spatial distribution of underground faults and fractures, to study their stress mechanisms in depth, and to predict the development and activity of faults and fractures. Due to its high energy, P-waves can effectively penetrate to deeper underground areas, and are therefore widely used in many exploration scenarios. In contrast, S-waves are more sensitive to the anisotropy of the medium than P-waves. Although their propagation speed is slower, they have significant advantages in improving the accuracy of fault and fracture imaging, playing a vital role in improving imaging resolution.

[0003] However, under current technological conditions, P-wave and S-wave controlled seismic sources are independent of each other. This means that in actual exploration operations, if simultaneous acquisition of P-wave and S-wave data is desired, separate P-wave and S-wave controlled seismic source devices must be deployed. Operating two different devices simultaneously in the same work area not only requires a series of tedious and time-consuming tasks such as equipment transportation, installation, and debugging, significantly increasing manpower, material resources, and time costs, but also presents significant challenges in coordinating the two devices. This places higher demands on site conditions and requires operators to possess more sophisticated skills; even slight errors can lead to low overall operational efficiency, failing to meet the stringent requirements of efficiency and accuracy in modern exploration work, and demonstrating significant limitations in practical applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A small-tonnage self-propelled controllable vibration source capable of achieving dual-wave vibration includes a vehicle frame assembly.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6A small-tonnage self-propelled controllable vibration source capable of achieving dual-wave vibration includes a complete vehicle frame assembly, which is composed of a front frame assembly 1, a rear frame assembly 2, and a hinge joint 3. The front frame assembly 1 and the rear frame assembly 2 are movably connected through the hinge joint 3 to adapt to the attitude adjustment of the vehicle under different terrains.

[0029] The vehicle frame assembly is equipped with two drive mechanisms 4, two motors 5 and a drive axle 6. The two drive mechanisms 4 are respectively connected to the front and rear motors 5. The output shaft of the motor 5 is directly connected to the drive axle 6. The forward and reverse rotation of the motor 5 drives the drive axle 6, thereby driving the wheels to realize the forward and reverse movement of the whole vehicle.

[0030] The front frame assembly 1 houses the cab assembly 7 and the fuel tank 8. The rear frame assembly 2 houses the lifting and guiding system 9, as well as the powertrain 10, hydraulic control system 11, hydraulic oil radiator 12, hydraulic oil tank 13, and battery box assembly 14. The rear frame assembly 2 is equipped with a longitudinal wave vibrator assembly 16 and a transverse wave vibrator assembly 17 via a double lower pressure plate mechanism 15. The double lower pressure plate mechanism 15 is bolted to both the longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17, facilitating quick replacement according to exploration needs.

[0031] The dual lower pressure plate mechanism 15 is specifically composed of a longitudinal wave lower pressure plate mechanism and a transverse wave lower pressure plate mechanism. The longitudinal wave lower pressure plate mechanism and the transverse wave lower pressure plate mechanism have different structures and are adapted to the installation requirements of the longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17, respectively. The two are connected to the front frame of the rear frame assembly 2 through different mounting holes.

[0032] The cab assembly 7 and fuel tank 8 are specifically mounted above the front frame assembly 1. The cab assembly 7 is fixedly mounted above the front frame assembly 1 via shock absorber brackets, providing the driver with a stable and comfortable operating environment. The fuel tank 8 is fixed to the front frame assembly 1 via welding or high-strength bolts and is connected to the fuel input line of the powertrain 10, continuously supplying it with fuel. The lift guide system 9 is specifically mounted at the front of the rear frame assembly 2. The lift guide system 9 is connected to the front frame of the rear frame assembly 2 by welding, and the lift guide system 9 has guide columns and sliders inside, enabling reciprocating mechanical movement in the vertical direction.

[0033] The powertrain 10, hydraulic control system 11, hydraulic oil cooler 12, hydraulic oil tank 13, and battery box assembly 14 are mounted on the rear side of the rear frame assembly 2. The powertrain 10 is fixed to the rear side of the rear frame assembly 2 via shock-absorbing pads, and its output shaft is connected to the hydraulic pump to provide power to the entire hydraulic system. The hydraulic control system 11 is bolted to the rear frame assembly 2 near the powertrain 10 for easy wiring and control connection. The hydraulic oil cooler 12 is connected to the hydraulic oil tank 13 and the hydraulic control system 11 via pipelines and is installed in a location that facilitates heat dissipation, such as the outer side of the rear side of the rear frame assembly 2. The hydraulic oil tank 13 is fixed to the rear side of the rear frame assembly 2 via brackets to store hydraulic oil for the hydraulic system. The battery box assembly 14 is bolted to the rear side of the rear frame assembly 2 and is connected to the vehicle's electrical system to supply power.

[0034] The longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 are mounted on the front frame of the rear frame assembly 2. The longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 are connected to the front frame of the rear frame assembly 2 via a double lower pressure plate mechanism 15. The longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 share a hydraulic system. The hydraulic control system 11 includes a switching valve group. When switching between longitudinal and transverse wave vibrations is required, the flow direction of the hydraulic oil is changed by controlling the solenoid directional valve of the switching valve group, causing it to flow into the corresponding working oil circuit of the longitudinal wave vibrator assembly 16 or the transverse wave vibrator assembly 17, thereby achieving the switching between the two wave vibrations.

[0035] The powertrain 10 consists of an engine, engine cooling system, intake and exhaust system, transfer case, vibration pump, drive pump, tandem pump, and soundproof enclosure. The hydraulic oil cooler 12 is integrated into the engine cooling system. The engine's output shaft is connected to the transfer case, which transmits power to the vibration pump, drive pump, and tandem pump to meet different functional requirements such as vibration and drive. The engine cooling system uses water cooling, and the hydraulic oil cooler 12 is integrated with the engine radiator's water circuit, utilizing the engine cooling system's coolant to dissipate heat from the hydraulic oil, improving cooling efficiency and saving space.

[0036] The hydraulic control system 11 includes a high-pressure control system assembly, a low-pressure control system assembly, a lifting control system assembly, and a drive control system. The high-pressure control system assembly is responsible for controlling the high-pressure hydraulic oil required for the operation of the longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 to achieve vibration output at different frequencies and amplitudes. The low-pressure control system assembly is mainly used to control some auxiliary equipment and low-pressure oil circuits. The lifting control system assembly controls the lifting guide system 9 to make the longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 press down to couple with the ground during operation and lift up to connect with the frame during movement. The drive control system controls the speed and direction of the motor 5 to realize the forward and backward movement of the vibration source. The battery box assembly 14 not only supplies power to the electrical equipment of the seismic source itself, such as lighting and control systems, but also supplies power to equipment that needs to be matched with the seismic source, such as seismic data acquisition equipment, through a dedicated output interface during construction. The hydraulic oil tank 13 provides hydraulic oil to the entire hydraulic system. Its capacity is designed to meet the needs of the seismic source for long-term continuous operation. In addition, the hydraulic oil tank 13 is equipped with a filter device to ensure the cleanliness of the hydraulic oil and extend the service life of each component of the hydraulic system.

[0037] In use, the vehicle is connected to the front frame 1 and rear frame assembly 2 via a hinge joint 3 to adapt to the terrain. Two sets of drive mechanisms 4 are connected to a motor 5 that directly drives the drive axle 6 for movement. The fuel tank 8 of the front frame assembly 1 powers the powertrain 10, which in turn powers the vibration and drive functions via a transfer case. The lifting guide system 9 at the front of the rear frame assembly 2 controls the up and down movement of the vibrator, with related systems arranged on the sides and rear. The longitudinal wave vibrator assembly 16 and the transverse wave vibrator assembly 17 are mounted at the front of the rear frame assembly 2 via a double lower pressure plate mechanism 15, sharing a hydraulic system. Switching between the two waves is achieved by changing the oil flow through the switching valve group of the hydraulic control system 11. The battery pack assembly 14 provides power, and the hydraulic oil tank 13 supplies oil to the hydraulic control system 11. All systems work together to complete the vibration source operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
