Description

Technical Field

[0001] This utility model relates to the field of actuator technology, and in particular to a handheld lithium-ion portable mobile valve opener and a worm gear reducer having the handheld lithium-ion portable mobile valve opener. Background Technology

[0002] In the construction of water conservancy projects such as irrigation districts, valves, as the core components of fluid control systems, are widely used in fields such as chemical industry, oil and gas extraction, urban water affairs, and power operation and maintenance. The efficiency, safety, and adaptability of their opening / closing operations directly affect the continuity of industrial production and the safety of workers.

[0003] As industrial scenarios upgrade towards "mobile inspection" and "unmanned operation and maintenance," and the demand for operations in hazardous environments (such as toxic media, high-pressure pipelines, and high-altitude platforms) increases, traditional valve opening tools are gradually revealing insurmountable technical defects. Many valves on pipelines are operated manually because they do not need to be opened and closed frequently. However, manual valve opening tools (such as wrenches and socket valve openers) are still widely used when opening, closing, or maintenance is required. These tools rely on human power to drive the valve stem rotation, resulting in high physical exertion, low operating efficiency, and low precision. Utility Model Content

[0004] The purpose of this application is to provide a handheld lithium-ion battery-powered portable valve opener and a worm gear reducer with the handheld lithium-ion battery-powered portable valve opener. It uses a DC motor and a worm gear reducer to control the operating mode and speed of the valve opener through current control. The portable valve opener is powered by a battery pack, which can be AC ​​charged when the battery pack is depleted. This greatly reduces the labor intensity of the operator and saves a lot of time. The electric device and the battery pack can be carried separately. It is small in size, lightweight, safe and reliable.

[0005] To achieve the above objectives, this utility model provides a handheld lithium battery portable mobile valve opener, including a handheld housing and a DC motor drive assembly disposed within the handheld housing. The DC motor drive assembly is detachably fixed within the handheld housing, and the power output shaft at one end of the DC motor drive assembly passes through the side of the handheld housing and extends to the outside of the handheld housing. A lithium battery module is detachably fixed to the other end of the DC motor drive assembly away from the power output shaft, and the lithium battery module is electrically connected to the DC motor drive assembly.

[0006] To facilitate the assembly and disassembly of various components within the handheld housing, the handheld housing includes a hollow outer shell and a front plate and a rear cover plate that are detachably fixed to both ends of the hollow outer shell.

[0007] To facilitate the assembly and disassembly of the DC motor drive assembly, the DC motor drive assembly includes a DC motor core, a support shaft, and a rear plate. The support shaft is housed within a hollow housing, with its front end detachably connected to a front receiving plate and parallel to the horizontal plane. The rear plate is detachably fixed to the rear end of the support shaft and is parallel to the front receiving plate. The rear end of the DC motor core is detachably connected to the rear plate, and the front end of the DC motor core is connected to the front receiving plate via a bearing. The power output shaft of the DC motor core passes through the front receiving plate and extends to the outside of the front receiving plate, and is parallel to the support shaft.

[0008] To facilitate the docking and fixing of this handheld lithium-ion portable mobile valve opener with the worm gear reducer, a connecting plate is detachably fixed to the outside of the front connecting plate, and the connecting plate is provided with several threaded holes.

[0009] To facilitate the assembly and disassembly of the lithium battery module, a bracket is detachably fixed on the rear plate, and the lithium battery module is detachably fixed on the bracket.

[0010] To facilitate charging of this handheld lithium-ion portable mobile valve opener, a charging connector is fixed to the outside of the rear cover, and the charging connector is electrically connected to the lithium-ion battery module.

[0011] To facilitate the control of the DC motor core, a control board is fixed to the outside of the rear cover plate, and the control board is electrically connected to the DC motor core.

[0012] To facilitate handheld use, a handle is detachably fixed to the top of the hollow outer shell.

[0013] This utility model also provides a worm gear reducer, on which the above-mentioned handheld lithium battery portable mobile valve opener is detachably connected.

[0014] Compared with existing technologies, this design has the following advantages: (1) Extreme portability: Breaking through the limitations of "space and cables" Traditional electric valve opening devices mostly rely on wired power supply (such as plug-in type) or are bulky (such as fixed drive device), and cannot flexibly meet the valve opening needs of multiple positions and mobility; while the portability advantage of this product directly addresses this pain point: Wireless freedom: Powered by lithium batteries, it completely eliminates the constraints of cables. There is no need to find power outlets or drag long cords. It can be easily moved and operated in scenarios without fixed power sources, such as workshops, outdoor pipelines, and high-altitude platforms. It is especially suitable for "moving and opening valves" scenarios such as inspections and temporary maintenance.

[0015] Lightweight design: The combination of "handheld form" and "worm gear reducer" greatly reduces the overall weight of the equipment. Operators can operate it with one hand without having to carry heavy equipment, and it is less tiring to use for a long time.

[0016] (2) Significantly saves effort and increases efficiency: reduces physical exertion and improves operational efficiency. Manually opening valves (especially large-diameter, high-pressure, or long-unused valves) is laborious, time-consuming, and prone to slippage. The combination of a worm gear reducer and valve opener fundamentally solves these problems. Worm gear reducers amplify torque: Worm gear reducers output high torque through gear transmission, allowing a single person to easily open / close the device by hand, avoiding hand strain, slippage, and injury caused by excessive manual force. They are especially suitable for old valves that are rusty or stuck.

[0017] Increased valve opening speed: Compared to manual operation with dozens or even hundreds of rotations, electric drive enables "one-button start and stop". The valve opening speed can be adjusted according to needs (such as slow opening to prevent impact, fast opening to improve efficiency). The operation time of a single valve is reduced from several minutes to tens of seconds. The efficiency improvement is particularly significant in scenarios that require batch operation of multiple valves (such as switching production lines in a workshop).

[0018] Operational stability: The valve opener avoids the problem of uneven force in manual operation (such as wear on valve seals caused by sudden changes in speed when opening the valve manually). The uniform speed transmission of the worm gear reducer makes the valve opening and closing process smoother, reduces the impact on the internal structure of the valve, and indirectly extends the service life of the valve.

[0019] (3) Economic, environmentally friendly and easy to use: Reduced long-term costs and low learning curve From the perspective of long-term use and maintenance, this product also has the advantages of "low cost, easy maintenance and easy to use": Economical and environmentally friendly: Lithium batteries are rechargeable, which is more environmentally friendly than disposable dry batteries and has lower long-term operating costs; the equipment has a simple structure (mainly lithium batteries, motors, and reducers), with no complex or easily damaged parts, and maintenance only requires periodic battery replacement or reducer cleaning, without the need for professional maintenance personnel.

[0020] Low learning curve: The user interface is simple (usually only has 3 settings: "on / off / stop"), requiring no professional training. Ordinary workers or inspectors can master the use of the tool in a few minutes. It is especially suitable for factory shift work or temporary staffing scenarios, avoiding operational delays caused by "not knowing how to use the tool". Attached Figure Description
