[0034] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0035] The following will describe in detail the Figure 1 intelligent hydraulic drive method for a vibratory source generator provided by the present invention.

[0036] Figure 1 It is a flowchart of an intelligent hydraulic drive method for a vibratory source generator provided by the present invention.

[0037] As Figure 1 shown, the intelligent hydraulic drive method for the vibratory source generator includes:

[0038] S1. Install a DC generator on the top of the vibratory source cab;

[0039] Installing the DC generator on the top of the vibratory source cab, the amplitude at the top part of the vibratory source cab is small, far from the engine with high temperature and the vibratory source ram with high-intensity vibration. The vibration frequency of the vibratory source ram is 1.5 - 96 Hz, the amplitude is 0 - 9.8 cm, the engine is relatively close to the ram, and the vibration intensity and amplitude are also large. The girder of the vibratory source is articulated, the ram and the engine are installed on the rear girder, and the cab is installed on the front girder. By installing the DC generator on the top of the vibratory source cab of the present invention, far from the ram and the engine with large vibration intensity, that is, working in a place with small mechanical vibration amplitude, the life damage of the DC generator caused by mechanical vibration is reduced, and it is beneficial to the dissipation of the internal temperature of the DC generator, avoiding the damage of the DC generator working in a high-temperature environment for a long time.

[0040] Figure 2 It is a schematic diagram of the connection between a hydraulic motor and a DC generator provided by an embodiment of the present invention; wherein, 1 - hydraulic motor, 2 - generator;

[0041] Figure 3 It is a working schematic diagram of a gear pump provided by an embodiment of the present invention;

[0042] S2. Connect a hydraulic motor with an external gear pump with a rotational speed of 1400 - 4000 R / min to the DC generator;

[0043] In the above S2, the connection method is a jaw coupling. The present invention adopts the jaw coupling method, which has good shock absorption, buffering, and insulation effects, does not require lubrication, is simple to maintain, has a certain axial, radial, and angular compensation ability, and has a long service life, being both safe and reliable.

[0044] In the prior art methods, since the DC generator does work on its pulley in one direction by belt drive, the rotating shaft of the DC generator deviates from the axis for a long time and rotates irregularly, resulting in damage. The present invention uses a hydraulic motor with an external gear pump with a rotational speed of 1400 - 4000R / min to drive the rotating shaft of the DC generator, effectively avoiding the above drawbacks.

[0045] Figure 4 It is a schematic diagram of the working principle of the DC generator provided by an embodiment of the present invention. Among them, 1. Low-pressure manifold, 2. Hydraulic motor, 3. Generator, 4. High-pressure manifold, 5. Flow regulating valve, 6. Controller.

[0046] Figure 5 Schematic diagram of the relationship between generator speed and voltage.

[0047] As Figure 4 shown, install the DC generator on the top of the vibroseis cab. Then, lead out a hydraulic oil circuit from the high-pressure manifold of the vibroseis drive pump, and install components such as a flow regulating valve and the hydraulic motor on the circuit. The hydraulic motor drives the generator to work. In addition, connect a controller to the flow regulating valve. The controller has the function of monitoring the main circuit voltage. When it monitors that the main circuit voltage decreases, the controller adjusts the flow regulating valve to increase the hydraulic oil flow, thereby increasing the generator speed.

[0048] As Figure 5 shown, since the generator speed is proportional to the main circuit voltage, the main circuit voltage is increased to meet the requirements of the electrical equipment.

[0049] S3. The rotating shaft of the DC generator is driven by the external gear pump hydraulic motor with a rotational speed of 1400 - 4000R / min, and the DC generator operates under the condition that the rotational speed is controlled at the rotational speed set value;

[0050] Among them, the rotational speed set value is 2000R / min, which is the optimal operating rotational speed value of the DC generator;

[0051] In step S3, the hydraulic motor with an external gear pump with a rotational speed of 1400 - 4000R / min drives the rotating shaft of the DC generator in a state of 3200PSI hydraulic pressure.

[0052] Step S3 includes:

[0053] S31. Control the external gear pump hydraulic motor with a rotational speed of 1400 - 4000R / min at 2000R / min;

[0054] In S31, while controlling the external gear pump hydraulic motor with a rotational speed of 1400 - 4000 R / min at 2000 R / min, the generated voltage of the DC generator is greater than 13.8V.

[0055] When the rotational speed of the external gear pump hydraulic motor with a rotational speed of 1400 - 4000 R / min is lower than 2000 R / min, the generated voltage of the DC generator is lower than 13.8V. When the rotational speed of the external gear pump hydraulic motor with a rotational speed of 1400 - 4000 R / min is 2000 revolutions per minute, the generated voltage of the DC generator is 13.8V. Only at this time can the normal demand of the electrical equipment be maintained. Among them, 13.8V is the voltage value for the DC generator to charge the battery.

[0056] S32. The shaft of the DC generator is driven by the external gear pump hydraulic motor with a rotational speed of 1400 - 4000 R / min, and the controller automatically controls and adjusts the valve core of the flow regulating valve so that the DC generator operates at the set rotational speed state.

[0057] In S32, the shaft of the DC generator is driven by the external gear pump hydraulic motor with a rotational speed of 1400 - 4000 R / min, and the transmission ratio is 1:1.

[0058] S32 further includes:

[0059] The DC regulating valve is connected to the controller, and the controller collects the data of the main circuit voltage. When the voltage of the main circuit is lower than 13.8V, the controller automatically controls the valve core of the flow regulating valve. Among them, the voltage of the main circuit is equal to the generated voltage of the DC generator.

[0060] After S3, it further includes: installation and commissioning, stability improvement, and safety protection.

[0061] The parameters targeted by the installation and commissioning and stability improvement include: the rotational speed of the generator and the voltage of the DC generator. The safety protection is to put a protective cover outside the shaft of the jaw coupling.

[0062] S4. According to the power consumption needs, load at least one of the DC generators.

[0063] Since there are many electrical equipment equipped on the vibroseis, including: electronic navigation, vibroseis vibration controller, communication radio, and other monitoring facilities and lighting lamps and other electrical equipment, which increases the power consumption demand. According to the power consumption needs, several DC generators can be loaded. It changes the previous mode that only one generator can be driven by one engine, and realizes loading multiple generators to increase the power generation and meet the power consumption demand of the electrical equipment.

[0064] In the present invention, a DC generator is installed on the top of the vibroseis cab, i.e., at a place with small mechanical vibration amplitude, which reduces the life damage of the DC generator caused by mechanical vibration and is beneficial to the dissipation of heat generated by the internal temperature of the DC generator. A hydraulic motor is used to drive the rotation of the DC generator shaft, effectively avoiding the damage caused by the irregular rotational movement of the DC generator shaft deviating from the axis for a long time due to the DC generator doing work on its pulley in one direction by belt drive in the prior art method; avoiding the damage of the DC generator working in a high-temperature environment for a long time; according to needs, one or several DC generators can be added, providing a guarantee for meeting more power consumption requirements.

[0065] Embodiment 1

[0066] Figure 4 It is a schematic diagram of the working principle of the DC generator provided by the embodiment of the present invention;

[0067] Among them, 1 - low-pressure manifold, 2 - hydraulic motor, 3 - generator, 4 - high-pressure manifold, 5 - flow regulating valve, 6 - controller.

[0068] As Figure 4 shown, a hydraulic motor with an external gear pump with a rotational speed of 1400 - 4000R / min and a DC generator are installed on the anti-roll frame of the vibroseis, i.e., the top of the vibroseis. A 1 / 2 hydraulic pipe is led out from the high-pressure manifold. The hydraulic pipe is connected in series with the flow regulating valve. The flow regulating valve is connected in series with the hydraulic motor. The hydraulic motor and the DC generator are connected by a jaw coupling. The DC generator is driven to work by the hydraulic motor. The hydraulic oil output from the hydraulic motor returns to the low-pressure manifold to form a hydraulic oil circuit.

[0069] In addition, a controller is connected to the flow regulating valve. The controller has the function of monitoring and collecting the main circuit voltage. When it monitors that the main circuit voltage decreases, the controller adjusts the flow regulating valve to increase the hydraulic oil flow rate, thereby increasing the generator speed.

[0070] Adjust the flow regulating valve. When the rotational speed of the hydraulic motor is 1500R / min and the generated voltage of the generator is 13.2V, continue to adjust the flow regulating valve so that the rotational speed of the hydraulic motor is 2000R / min and the generated voltage of the DC generator is 13.8V to meet the power consumption requirements of the electrical equipment.
