[0020] The tank lighting system and the tank signal dot device are equipped with 2 high-brightness LED lights in each tank cage, and a human infrared recognition device is installed. When someone is detected in the tank, the lighting is automatically turned on. When there is no one in the tank, the lighting is automatically turned off. The lighting control mode is divided into manual and automatic modes, and it can also be set to a forced open state on the human-machine interface of the ground control cabinet; this system can expand the installation of fixed signals and vehicle control devices in the tank to realize the switch control of the safety door and the rocking platform in the tank, and the function of sending the start signal in the tank. There is no need to extend the hand outside the tank to operate, which ensures the personal safety of the tank signal worker. The tank cage signal dot device is equipped with a 10-inch human-machine interface, which can realize the direction selection, lifting, lowering, slow up, slow down, parking and other signal sending, and can also manually switch the safety door and rocking platform. And it is locked with the hoist system to ensure the safe and reliable operation of the equipment. It can display the operation status of the hoist, cage position, operation speed, signal direction, the middle section of the tank, the locking status of each middle section, etc., so that the signal and tank workers can understand the operation data of the hoist and signal system in real time. When the cage stops abnormally in the middle of the shaft, the cause of the hoist failure can be checked through the touch screen. After the failure is eliminated, the start signal can be sent anytime and anywhere.

[0021] Wireless charging consists of a transmitter controller, a transmitter board, a receiver board and a receiver control. The components are connected by radio. The receiver board is installed on the lateral edge of the top of the cage. When the cage stops at the wellhead parking space, the receiver board is just aligned with the transmitter board. At this time, the ground PLC control cabinet is connected to the transmitter controller to work. The induced alternating voltage received by the cage side is processed by the receiver controller installed in the tank to charge the lithium battery, and an overcharge protection is set. Wireless charging adopts magnetic induction, with a long induction distance, high charging efficiency, no sparks, automatic control and maintenance-free. The structure adopts a modular design, including a transmitter board, a transmitter controller, a receiver board and a receiver controller. The above components are all cast and sealed, with a high level of protection. The charging induction distance is controllable from 30 to 200 mm, and the maximum charging power of a single module can reach more than 300W, and multiple modules can be used in parallel. The transmitter input power supply voltage is 36V, which adapts to a wide range of voltage fluctuations. The receiver outputs a voltage of 24V, which is specially designed for lithium batteries and automatically adapts to the battery voltage of 22.5-25.5V. The wireless charging system has multiple safety protections, including power supply voltage abnormality protection, charging power abnormality protection, output side voltage abnormality protection, output short circuit, overcurrent, overload protection, output power limitation, etc. And it has a fault self-reset function.

Lithium iron phosphate batteries have the characteristics of good heat resistance, long service life, safety and environmental protection. The battery pack has protection functions such as overcurrent, short circuit, overcharge, and power loss. Equipped with 1 spare lithium battery pack, under normal circumstances, this wireless charging system can meet the continuous power demand of the entire system, and there is no need to replace the battery pack.

[0022] The two-way voice intercom system includes fixed voice intercom devices in the upper and lower cages, the inlet signal room, the centralized control center and the dispatch center. The components are connected by radio. Fixed voice intercom devices are configured in the upper and lower cages, the wellhead signal room, the centralized control center and the dispatch center to realize voice calls and information exchanges between the tank passengers and the wellhead and the ground, and enhance the safety of the system. Especially when the tank stops due to a fault, it plays a very important role in emotional comfort and rescue communication for the trapped personnel in the tank. In addition, 3 handheld intercoms are configured to realize long-distance, reliable and real-time voice intercom between the cage and the ground when the wellbore equipment is repaired on the top of the tank. The voice intercom device in the tank adopts a stainless steel shell, wall-mounted installation, waterproof design, with a thickness of about 40mm, and almost no space in the cage. It adopts POE power supply and only needs to connect 1 network cable to use it. The volume of the loudspeaker is adjustable, and the radio microphone is directional, which can prevent noise storms and automatically filter, so as to realize high-definition voice calls and information exchanges between the tank passengers and the wellhead and the ground. The ground voice intercom equipment also uses the above-mentioned voice intercom device, which can be connected to any node of the local ring network in the mining area with a desktop gooseneck transmitter. In order to facilitate reliable communication with the ground when standing on the tank top to inspect the shaft equipment, three high-power waterproof handheld intercoms are equipped. Through the wireless communication base station installed on the tank cage, the ground is relayed to communicate with the wellhead hoisting driver and the centralized control center at any position in the shaft. The signal delay is no more than 500ms.

[0023] The wireless video system includes a wide-angle camera, a ground receiving device, and a ground monitoring system. The components are connected by radio. A wide-angle camera is installed on the top of the cage to achieve 360° video monitoring without blind spots. Starlight night vision technology is used to enable high-definition monitoring even without lighting, and the sound inside the cage can also be monitored. The audio and video wireless communication is sent to the ground receiving device, and then connected to the ground monitoring system (signal room, control room, dispatch room, etc.) to achieve real-time video monitoring inside the cage, and is equipped with a 2T hard disk recorder to store video for no less than 30 days. This system can display important data such as the speed and position of the hoist in the cage video image, and store the data in the hard disk recorder after fusion, so as to facilitate the synchronous understanding of the hoist operation status during video playback and facilitate fault finding and analysis. A 24-inch monitor is configured in the wellhead signal room to display real-time video images inside the cage.

[0024] The wireless communication system consists of a PLC control cabinet in the wellhead signal room, a wellhead directional data transceiver base station, a tank top directional data transceiver base station, and a tank data processing PLC control box.

The servo drive motor is an integrated integrated motor with small size and high integration. The maximum power reaches 350W. By pulling the tank curtain door crossbar up by two chains, it can ensure that the crossbar is lifted in parallel and not easy to get stuck. The lifting speed of the tank curtain door crossbar is not less than 0.3m / s. The servo motor has overload and overspeed protection, which can ensure the smooth and reliable opening and closing of the tank curtain door. At the same time, it has accurate position records to ensure that the tank curtain door will not be over-rolled or over-released. It also has a power-off brake mechanism to ensure that the tank curtain door is locked securely after being lifted to avoid accidental falling and causing injuries to personnel. The distance between the curtain rods of the door is not more than 200mm, the height of the bottom cross bar of the door curtain from the ground of the tank cage is not more than 250mm, and the total height of the highest point of the curtain rod of the door from the ground of the tank cage is not less than 1.25 meters. After the door is opened, the total lifting height of the door curtain is not less than 1.8 meters. For special large-piece material transportation, it only needs to remove the bolts at the four corners of the tank curtain door to completely remove it, which is easy to disassemble. The door curtain can also be raised to the highest height of the tank cage door manually. A spare hook is reserved at the top of the tank curtain door. When the electrical control part fails or the transmission mechanism is blocked, causing the tank curtain door to be unable to be lowered into place, it can be quickly unlocked within 10 seconds by releasing the quick-connect ring lock at the bottom of the cross bar, and the tank passengers can manually retract and release the tank curtain door to ensure that personnel can enter and exit the tank cage safely and quickly. Equipped with 2 handheld remote controllers, the tank curtain door can be remotely opened and closed within 10 meters of the horse head door. The remote controller adopts wear-resistant, high-strength engineering plastic shell, with a protection level of not less than IP54, and is powered by a rechargeable lithium battery. The tank curtain door is set with two working modes: manual and automatic. The remote controller is equipped with three function keys: lifting, lowering, and stopping. The upper and lower tank curtain door control buttons are set separately. In automatic mode, the system automatically executes the opening and closing of the tank curtain door according to the tank cage in place stop signal and the signal system start signal. Whether it is manual or automatic mode, the tank curtain door is locked with the main lifting and signal system, that is, when the tank cage is not in place, the tank curtain door cannot be opened; when the tank curtain door is not closed in place, the hoist is not allowed to run; during the operation of the tank cage, the tank curtain door transmission system is powered off to ensure that the tank curtain door will not be opened by mistake.
