Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the exemplary embodiments to those skilled in the art.

[0043] As Figure 1As shown, the application discloses a container mutual control system, which mainly comprises a remote container and an explosion-proof power unit container, and the remote container and the explosion-proof power unit container can be interconnected and controlled. The explosion-proof power unit container can provide power, such as gas, hydraulic oil and power supply, to the remote container. Therefore, the explosion-proof power unit container can open and close the gas source and the hydraulic oil source of the remote container, and can open and shut off the power supply provided to the remote container.

[0044] The remote container according to the application can be a trailer such as a general container, a special container and a marine container, and the explosion-proof power unit container is a power trailer.

[0045] As shown in Figure 1 and Figure 2 , the remote container mainly comprises a remote control module. The explosion-proof power unit container mainly comprises an explosion-proof power unit control module 10, a fire gas detection module and a fire control module. The explosion-proof power unit control module 10 is electrically connected with the remote control module, and the two can transmit signals and data to each other. The fire gas detection module is electrically connected with the explosion-proof power unit control module 10, and the fire gas detection module is used to send the detected fire gas detection signal to the explosion-proof power unit control module 10. The fire control module is electrically connected with the explosion-proof power unit control module 10. After receiving the fire gas detection signal, the explosion-proof power unit control module 10 determines whether the explosion-proof power unit container has a fire or has flammable gas, triggers a fire alarm prompt after determining that the explosion-proof power unit container has a fire or has flammable gas, controls the fire control module to perform corresponding actions, sends the fire alarm signal to the remote control module, the remote control module correspondingly issues a fire alarm prompt, stores and displays the fire alarm signal and historical records, and sends the fire alarm signal to the central control room.

[0046] 4 Figure 1 and Figure 4 As shown, the fire gas detection module comprises a fire detection device 40 and a flammable gas detection device 50. The fire detection device 40 is electrically connected with the explosion-proof power unit control module 10 to send the detected fire detection signal to the explosion-proof power unit control module 10. The flammable gas detection device 50 is electrically connected with the explosion-proof power unit control module 10 to send the detected flammable gas detection signal to the explosion-proof power unit control module 10. The fire gas detection signal comprises the fire detection signal and the flammable gas detection signal. The fire detection device 40 can at least comprise a smoke detector, and can further comprise a temperature sensor.

[0047] The explosion-proof power unit container further comprises an engine and an engine control module 20, which are electrically connected with the engine and the explosion-proof power unit control module 10 respectively, so as to be capable of sending the collected engine state signals to the explosion-proof power unit control module 10.

[0048] After receiving the engine state signals, the explosion-proof power unit control module 10 determines whether the engine is abnormal, and triggers an engine abnormality alarm prompt after determining that the engine is abnormal, and sends an engine abnormality alarm signal to the remote control module. The remote control module correspondingly issues an engine abnormality alarm prompt, stores and displays the engine abnormality alarm signal, and sends the engine abnormality alarm signal to the oilfield platform facility central control room. Further, the remote control module can send an engine control signal to start or shut down the engine to the explosion-proof power unit control module 10.

[0049] In addition, the alarm switch signal of the engine control module 20 can also be output to the explosion-proof power unit control module 10 for alarm and control. Therefore, the remote container can monitor the state of the engine of the explosion-proof power unit container in real time, display historical alarm information and fault records, and at the same time set and modify the configuration, alarm upper and lower limits and other technical parameters of the remote control module on the display screen. In order to be able to handle the abnormality of the engine of the explosion-proof power unit container in time, and to remotely start and shut down the engine, so that the explosion-proof power unit container can be suitable for offshore / land oil drilling operations.

[0050] Preferably, the remote control module receives the engine state signals only when it is determined that the internal environment of the remote container is in a positive pressure safety state. In the present embodiment, the engine control module 20 and the explosion-proof power unit control module 10 are communicatively connected, for example, can be connected through a communication line, or are wirelessly communicatively connected, to transmit signals and data between the two. In addition, the explosion-proof power unit control module 10 and the engine can respectively provide 24V power to the engine control module 20, so that in the case of power failure or failure of the container interlocking system, it does not affect the independent operation of the engine itself.

[0051] Specifically, the explosion-proof power unit control module 10 is communicatively connected with the engine control module 20, for example, connected through a communication line or connected through a switch signal, to receive the state parameters of the engine collected by the engine control module 20, that is, in the form of a transmitter state signal sent to the explosion-proof power unit control module 10. Specifically, the engine state signal includes a start-stop state signal, an oil pressure signal, a cooling water temperature signal, an exhaust temperature signal, a machine shell surface temperature signal, and a speed signal. That is, the start-stop state, oil pressure, cooling water temperature, exhaust temperature, machine shell surface temperature, and speed of the transmitter are collected by various detection devices and transmitted to the engine control module 20. For example, an engine cooling water temperature detection device and an exhaust temperature detection device can be provided, and the related detection devices will not be described in detail.

[0052] In the present embodiment, the explosion-proof power unit container can operate independently, specifically, can independently perform fire detection, fire alarm, engine start and stop, start the fire extinguisher 30 and extinguish the fire through the fire extinguishing nozzle, and can automatically trigger the closing of the shutter and the release of the fire extinguisher 30 after detecting the occurrence of a fire. The following will be described in detail.

[0053] As shown in Figure 1 , Figure 2 and Figure 4 , the explosion-proof power unit container further comprises a first alarm device 60, which is electrically connected with the explosion-proof power unit control module 10. The explosion-proof power unit control module 10 controls the first alarm device 60 to trigger an audible and visual alarm after determining that the explosion-proof power unit container has a fire, flammable gas, or the engine has an abnormality. And the remote control module can send a first alarm control signal to the explosion-proof power unit control module 10 to turn off the first alarm device 60 after receiving a fire alarm signal or an engine abnormality alarm signal for a predetermined time. When the explosion-proof power unit control module 10 determines that the explosion-proof power unit container has flammable gas and triggers the first alarm device 60 to issue an audible and visual alarm, the container interlocking system can control the engine to shut down when the flammable gas probe alarms.

[0054] The remote container further comprises a second alarm device, which is electrically connected with the remote control module. The remote control module controls the second alarm device to trigger an audible and visual alarm after receiving a fire alarm signal, and the explosion-proof power unit control module 10 can send a second alarm control signal to the remote control module to turn off the second alarm device after sending a fire alarm signal to the remote control module for a predetermined time.

[0055] The explosion-proof power unit container further comprises a shutter 70 and a fire extinguisher 30. The shutter 70 is an explosion-proof shutter. The shutter 70 and the fire extinguisher 30 are electrically connected with the explosion-proof power unit control module 10. The remote control module can send a shutter control signal to the explosion-proof power unit control module 10 to control the opening or closing of the shutter 70, and can send a fire extinguisher control signal to the explosion-proof power unit control module 10 to control the release of the fire extinguisher 30. When the explosion-proof power unit control module 10 determines that the explosion-proof power unit container has a fire, the explosion-proof power unit control module 10 controls the closing of the shutter 70 and the release of the fire extinguisher 30 (for example, an FM200 fire extinguisher 30). In addition, the fire extinguisher 30 can also be manually released by an operator.

[0056] The explosion-proof power unit container further comprises a shutter travel switch electrically connected with the explosion-proof power unit control module 10 to send a detected shutter travel signal to the explosion-proof power unit control module 10. When the explosion-proof power unit control module 10 determines that the shutter 70 is closed in place, the fire extinguisher 30 is released. According to the shutter 70 of the present embodiment, the shutter 70 can be opened or closed via a manual switch, Figure 3 The shutter switch device 71 for manually opening or closing the shutter 70 is shown in FIG. 8.

[0057] In the present embodiment, the fire gas detection module comprises two fire detection devices 40 and two combustible gas detection devices 50. When the explosion-proof power unit control module 10 determines that the explosion-proof power unit container has a fire after receiving the fire gas detection signals of the two fire detection devices 40, it is confirmed that the explosion-proof power unit container has a fire. The explosion-proof power unit control module 10 controls the shutdown of the engine, the closing of the shutter 70 and the release of the fire extinguisher 30. If it is confirmed to be a false alarm, the explosion-proof power unit control module 10 can cancel the alarm of the first alarm device 60.

[0058] In addition, when the operator finds that the explosion-proof power unit container has a fire during the inspection, the first alarm device 60 can be triggered manually to issue an audible and visual alarm, and the explosion-proof power unit control module 10 controls the shutdown of the engine, the closing of the shutter 70 and the release of the fire extinguisher 30 based on the manual triggering action. If the explosion-proof power unit container is in an automatic mode, the explosion-proof power unit control module 10 automatically triggers the shutdown of the engine, the closing of the shutter 70 and the release of the fire extinguisher 30. In addition, the audible and visual alarm of the first alarm device 60 can also be manually cancelled. After the alarm of the first alarm device 60 is manually cancelled, if there is indeed an alarm, it does not affect the control panel to continue to display the alarm information. The container interlocking system can test the fire detection device 40, and only control the system alarm, but not shut down the engine and release the fire extinguisher 30.

[0059] The following will be described in combination withFigures 2 to 5 The working principle of mutual control of the remote container and the explosion-proof power unit container is briefly described.

[0060] The operator presses the start button (not shown) in the remote container or the start button on the control panel of the engine control module 20 of the explosion-proof power unit container to start the electromagnetic valve 11 to open the control gas (see Figure 5 ), which makes the drive shaft gear 12 engage with the flywheel gear 13 of the diesel engine. The control gas opens the axial pneumatic valve (not shown), and the start gas enters the pneumatic motor 14, driving the turbine (not shown) to rotate at high speed, which drives the crankshaft 15 of the diesel engine to rotate to the specified speed. At this time, the electromagnetic valve 11 is automatically de-energized to cut off the control gas, and then the drive shaft gear 12 is reset, the pneumatic motor 14 stops running, and the diesel engine operates normally.

[0061] The drive shaft gear 12 of the diesel engine transmits the rotating power to the hydraulic piston pump 16. The hydraulic oil in the oil tank 17 above the hydraulic piston pump 16 flows into the working chamber of the hydraulic piston pump 16 through the oil pipe line, so that the oil pressure is continuously raised to form medium / high pressure hydraulic oil. The hydraulic oil is connected to the energy accumulator 18 and the manifold plate 19 through external pipe lines after pressure and flow regulation by electromagnetic reversing valve, throttle valve, overflow valve, etc.

[0062] The explosion-proof power unit container of the embodiment has at least one hydraulic piston pump 16, one of which serves as a backup device. The function of the hydraulic piston pump 16 is to convert mechanical rotational kinetic energy into hydraulic kinetic energy. When one of the hydraulic piston pumps 16 fails, the standby hydraulic piston pump 16 can be started at any time to ensure that the container can be used normally.

[0063] Due to the relatively compact internal space of the explosion-proof power unit container, the manifold plate 19 is provided to facilitate the hydraulic pipe line connection operation between the diesel engine and the container. When the logging downhole equipment is logging in the open hole section, it cannot be in a static state for a long time, otherwise an accident may occur downhole. When the diesel engine or the hydraulic piston pump 16 fails, the energy accumulator 18 can automatically release the medium / high pressure hydraulic oil stored inside to ensure the normal use of the explosion-proof power unit container for a certain period of time.

[0064] The hydraulic oil transmitted by the hydraulic oil pipe line connected from the hydraulic piston pump 16 is connected to the manifold plate 19 and then connected to the throttle valve 21 and the overflow valve 22 from the manifold plate 19. The throttle valve 21 and the overflow valve 22 are connected to the cable dispenser oil cylinder and the hydraulic motor 23. The power of the hydraulic motor 23 is transmitted to the speed reducer 24, and the power of the speed reducer 24 is connected to the drum 25 by a chain. The cable can be flexibly reeled and unreeled.

[0065] In the embodiment, the full-automatic hydraulic cable arranging device 26 moves the cable arranging rod transversely and longitudinally by two hydraulic cylinders, so that the cables can be arranged flat on the drum 25. The hydraulic motor 23 converts hydraulic energy into kinetic energy. The speed reducer 24 can flexibly control the rotating speed of the output power according to the speed and torque of the cable winding and unwinding, and the rotating direction. The throttle valve 21 is used to adjust and control the flow of the outlet hydraulic oil. The overflow valve 22 is used to overflow the excess hydraulic oil in the hydraulic system, so that the hydraulic system can maintain a certain pressure, limit the upper limit of the pressure, and prevent the hydraulic system from being overloaded.

[0066] The power supply of the interconnection control between the explosion-proof power unit container and the remote container is wound on the hooks in the cable cabin of the power unit container, and directly connected with the remote container through the explosion-proof latch. The explosion-proof power unit container of the embodiment is provided with four leakage grounding interfaces 27, which can be grounding bolts for example, to ensure personal safety and normal operation of the equipment.

[0067] Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The features described in one embodiment can be applied to another embodiment, either individually or in combination, unless that feature is not applicable or is otherwise stated.

[0068] The application has been described by the above embodiments, but it should be understood that the above embodiments are only for the purpose of example and illustration, and the application is not limited to the above embodiments. According to the teachings of the present application, more various modifications and changes can be made, and all of these modifications and changes fall within the scope of the application claimed.
