Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, in particular to a movable power supply device for coalbed methane mining wells. Background Art

[0002] With the growth of energy demand and the focus on clean energy, coalbed methane, as a clean energy with huge potential, has received more and more attention.

[0003] Usually, the power required for the mining well extraction equipment (screw compressor) is provided by a diesel generator burning diesel. After the extraction equipment operates normally, a stable gas source is extracted to supply power to the mobile gas generator.

[0004] However, diesel generators are expensive to operate and require regular refueling, making them extremely inconvenient. Coalbed methane itself can be used as a power generation fuel. Using mobile gas-fired generator sets, coalbed methane can be extracted from wells for on-site power generation, enabling self-use. However, mobile gas-fired generators require a stable gas supply before they can start. Extracting and providing a stable gas supply requires stable extraction equipment, which in turn requires a stable power supply.

[0005] However, the operating environment of coalbed methane production wells is usually harsh and remote, and the operating life of the production wells is usually only 1-2 years. The traditional fixed power supply method has difficulties and limitations. The cost of laying a dedicated power line is extremely high and the service life is short.

[0006] To address this issue, diesel generators have previously been used to first drive extraction equipment to extract the gas source, then operate mobile gas generators, and finally switch the power supply to the mobile gas generators. However, diesel generator sets are bulky and require trailers to be towed to the site of use, which consumes manpower and material resources. This utility model utilizes new energy vehicle batteries and converts them into external power supplies for extraction equipment through a DCAC module, greatly improving the efficiency of the initial power supply work in remote mining well sites and saving operating costs. In addition, in addition to providing temporary power, the new energy mobile power supply vehicle can also be used as a tool vehicle for daily use. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a movable power supply device for coalbed methane production wells.

[0008] The utility model is implemented by the following technical solution: a movable power supply device for coalbed methane mining wells, comprising an external mounting frame, the inner wall of the external mounting frame is fixedly connected to a fixed frame, both sides of the inner wall of the fixed frame are fixedly connected to guide rails, the middle part of the inner wall of the fixed frame is fixedly connected to a limiting plate, and the upper surface of the limiting plate is provided with a plurality of limiting holes.

[0009] Through the above technical solution, the external mounting frame provides a stable support structure to protect the internal components from the influence of the external environment. The fixed frame helps to maintain the correct position of the guide rail and the limit plate, ensuring that the mounting plate can move smoothly along the predetermined track. It also provides installation points for other fixed components. The guide rail allows the mounting plate to slide along its surface to achieve the movement of the device. The combination of the limit plate and the limit hole ensures that the movement range of the mounting plate on the guide rail is limited, preventing excessive movement from causing damage to the equipment or derailment, and increasing the safety of operation.

[0010] As a further improvement of the above solution, the upper surface of the guide rail is slidably connected to a plurality of mounting plates, and the bottom of the mounting plates is fixedly connected to reinforcing ribs.

[0011] Through this technical solution, the mounting plate carries important equipment such as fixed power supplies, extraction equipment and mobile gas generators. Its design must be able to adapt to the weight and size of different equipment to ensure the stability of the equipment during movement.

[0012] As a further improvement of the above solution, the four corners of the lower surface of the reinforcing rib are fixedly connected to a pulley housing, the interior of the pulley housing is rotatably connected to a pulley, and the pulley is adapted to the guide rail.

[0013] Through the above technical solution, the pulley system reduces the friction when the mounting plate moves on the guide rail, making the movement smoother, reducing energy consumption, and also alleviating the labor intensity during operation.

[0014] As a further improvement of the above solution, a connecting block is fixedly connected to the middle of the front end of the mounting plate, and a sleeve is fixedly connected to the middle of the upper surface of the connecting block.

[0015] Through the above technical solution, the design of the connecting block and the sleeve allows for quick connection and release of the mounting plate, facilitating assembly, disassembly and transportation of the equipment.

[0016] As a further improvement of the above solution, a fixing nail is sleeved inside the sleeve, and the fixing nail is adapted to the limiting hole.

[0017] Through the above technical solution, the cooperation between the fixing nails and the limiting holes ensures the correct position of the mounting plate on the guide rail, preventing displacement after fixation.

[0018] As a further improvement of the above solution, a connecting groove is provided in the middle of the rear end of the mounting plate, and the connecting groove is adapted to the connecting block.

[0019] Through the above technical solution, the connection groove is adapted to the connection block, providing a quick connection and release mechanism, so that multiple mounting plates can be tightly connected to form a unified mobile unit.

[0020] As a further improvement of the above solution, a fixed power source, an extraction device and a mobile gas generator are fixedly connected to the upper surface of the mounting plate in sequence from left to right.

[0021] Through the above technical solution, fixed power supplies, extraction equipment and mobile gas generators are the core working parts of the coalbed methane production well power supply device. They are responsible for providing electricity, performing gas production operations and providing backup energy to ensure the normal operation and energy supply of the production well.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By setting up a fixed power supply, extraction equipment and a mobile gas generator, the utility model can provide a stable power supply at different mining well locations, reduce energy waste and lower operating costs. The movable design of the device allows it to be quickly deployed and adjusted according to the specific location of the mining well and the operation requirements, thereby improving the adaptability of the operation. Through modular and standardized design, the maintenance and replacement of the overall device become simpler, thereby improving the reliability of the system and the stability of long-term operation.
