Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to a miniaturized encapsulation power-off device main unit. Background Technology
[0002] A methane power-off device is one type of power-off device. Existing methane power-off devices are generally used in conjunction with methane sensors to achieve real-time monitoring of methane concentration in the methane environment. (When the methane concentration reaches or exceeds the preset power-off value, the power-off device will immediately output a power-off command and cut off the power supply to the power-off device motor, causing the motor to stop running. This avoids dangerous situations such as gas explosions caused by sparks generated by the motor, ensuring production safety. When the methane concentration drops below the preset unlock value, the power-off device automatically unlocks, restoring power to the motor and allowing it to resume normal operation.)
[0003] Existing power-off motors used in methane power-off devices typically exhibit the following problems during practical use: 1. Due to the large size of the motor, including the circuitry, battery, and all other components (including studs), sufficient electrical clearance is required after electrical connections, resulting in poor compatibility during installation; 2. Existing power-off motors generally only support a single signal standard such as RS485. This limitation prevents them from being compatible with multiple devices (locomotives, monitoring systems) for integration. Summary of the Invention
[0004] In view of the above shortcomings, this utility model provides a miniaturized encapsulation power cut-off device host that can achieve small size, ensure installation adaptability, and meet explosion-proof requirements for reliable use.
[0005] To achieve the above objectives, this utility model employs a miniaturized encapsulation power-off device main unit, including a housing, a battery assembly, a main board, a power board, a display component, an isolation module, and studs distributed within the housing. The studs include welding studs located within the housing and used for mounting the main board, and positioning studs located on the main board and used for mounting the display component. A sandwich space is formed between the bottom surface of the housing and the display component. The battery assembly, motherboard, isolation module and power board are respectively distributed in the sandwich space. The mounting parts of the battery assembly, motherboard, power board, welding studs, limiting studs, isolation module and display component are respectively encapsulated in the housing, forming a compact distribution of the battery assembly, motherboard, power board, welding studs, isolation module, limiting studs and display component in the housing.
[0006] The present invention is further configured such that the motherboard integrates an RS485 module, a CAN module, a WIFI module, and a 4G module, and the RS485 module, CAN module, WIFI module, and 4G module respectively form signal interaction and working coordination with the circuit of the motherboard, and are configured to be used for methane concentration data, and after power failure, the data is collected and wirelessly transmitted to the outside.
[0007] The present invention is further configured such that the display component is an LCD screen, and the motherboard also integrates an infrared receiving circuit, a cyclic display module, and an interface parameter module with remote setting and local locking. The LCD screen, through the loop display module in the motherboard, forms a multi-state display interface that can be used to loop display methane concentration, power supply, alarm, and relay status, as well as a parameter interface that can be used for remote setting and local locking. The main unit of the power failure device is also compatible with an infrared remote control with a menu hierarchy design that is compatible with the infrared receiving circuit.
[0008] The present invention is further configured such that the housing is provided with a transmitter aviation socket, several explosion-proof glands, and several aviation plugs with connecting wires. The transmitter aviation socket is screwed with a transmitter, and the screw connection forms a quick-connect connection between the transmitter and the main unit of the power failure instrument. The several explosion-proof glands are used for intrinsically safe transmission between external signals and signals inside the housing.
[0009] The present invention is further provided that a window is provided on the housing in the area corresponding to the LCD screen, and a protective component is provided between the window and the LCD screen.
[0010] The present invention is further configured such that each of the explosion-proof glands is a stuffing box type explosion-proof cable clamping and sealing joint, and the explosion-proof cable clamping and sealing joint includes an O-ring. The explosion-proof cable is connected to the box through the stuffing box type explosion-proof cable clamping and sealing joint. The O-ring and the compression connection between the explosion-proof cable and the stuffing box type explosion-proof cable clamping and sealing joint form a sealed connection between the explosion-proof cable and the box, and constitutes waterproof, dustproof and explosion-proof protection for the connection of the explosion-proof cable to the box.
[0011] The present invention is further configured such that the protective component includes tempered glass distributed on one side of the LCD screen, a glass fixing frame fitted over the tempered glass, and a glass pressure plate distributed between the LCD screen and the tempered glass. Silicone pads are respectively provided between the tempered glass and the glass pressure plate, and on the side of the tempered glass that is away from the glass pressure plate. The protective component is limited to the inner top surface of the housing by the side of the glass fixing frame that is away from the glass pressure plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by separately encapsulating the battery components, motherboard, power board, display components, isolation module, welding studs, and limiting studs on the power-off device host into the housing, the necessary electrical spacing of the battery components, motherboard, power board, display components, isolation module, welding studs, and limiting studs can be shortened during the housing process. This makes the design between the various parts inside the housing more compact, and also reduces the volume of the housing to a certain extent. As a result, the power-off device host involved in this utility model can achieve miniaturization of the structural design while being used reliably. This also makes the power-off device host adaptable to more environments during installation and use, thus greatly improving the adaptability of the power-off device host. Attached Figure Description

Detailed Implementation
[0014] like Figure 1-9 As shown, a specific embodiment of this utility model is a miniaturized encapsulation power-off device main unit, including a housing 1, a battery assembly 5, a main board 8, a power board 20 distributed in the housing 1, a display component 6, an isolation module 7, and studs. The studs include an isolation module 9 that is limited within the housing 1 and used to mount the main board 8, and a limiting stud 10 that is limited on the main board 8 and used to mount the display component 6. A sandwich space 100 is formed between the bottom surface of the housing 1 and the display component 6. The battery assembly 5, the main board 8, the isolation module 7 and the power board 20 are respectively distributed in the sandwich space 100. The mounting parts of the battery assembly 5, the main board 8, the power board 20, the isolation module 9, the limiting stud 10, the isolation module 7 and the display component 6 are respectively encapsulated in the housing 1, and the battery assembly 5, the main board 8, the power board 20, the isolation module 9, the isolation module 7, the limiting stud 10 and the display component 6 are compactly distributed in the housing 1.
[0015] By separately encapsulating the battery assembly 5, main board 8, power board 20, display component 6, isolation module 7, isolation module 9, and limiting stud 10 on the power-off device main unit into the housing 1, the necessary electrical spacing between these components can be shortened. This makes the design of the various parts within the housing 1 more compact, thereby reducing the volume of the housing 1. As a result, the power-off device main unit of this invention can achieve a miniaturized structural design while ensuring reliable use. This also allows the power-off device main unit to be adapted to more environments during installation and use, greatly improving its adaptability.
[0016] like Figure 2-7 As shown, the motherboard 8 integrates an RS485 module, a CAN module, a WIFI module, and a 4G module. These modules interact and coordinate with the circuitry of the motherboard 8, forming a design for wirelessly transmitting methane concentration data and power outage status data. This design enables the power outage device to have WIFI and 4G wireless transmission capabilities, allowing it to wirelessly transmit collected methane concentration data and power outage status data to other devices during use. It also ensures the power outage device is compatible with multiple communication standards, allowing it to connect to various devices (such as locomotives and monitoring systems). This enhances the adaptability and compatibility of the power outage device and optimizes the user experience.
[0017] like Figure 2 , 4As shown in Figure 6, the display component 6 is an LCD screen. The main board 8 also integrates an infrared receiving circuit, a cyclic display module, and an interface parameter module with remote setting and local locking. The LCD screen, through the cyclic display module in the main board 8, forms a multi-state display interface that can be used to cyclically display methane concentration, power supply, alarm, and relay status, as well as a parameter interface that can be used for remote setting and local locking. The main unit of the power failure device is also designed with an infrared remote control that is compatible with the infrared receiving circuit and has a menu hierarchy design. This invention enables the main unit of the power-off device to display various data information intuitively via an LCD screen. Compared to the existing digital tube display method, this provides a more user-friendly interface. Furthermore, the main board 8 includes an infrared receiving circuit, a cyclic display module, and an interface parameter module with remote setting and local locking. The infrared receiving circuit enhances the anti-interference capabilities of the layout design of the main board 8. The cyclic display module improves the readability of the layout logic for methane concentration, power supply, alarm, and relay status on the LCD screen. The interface parameter module with remote setting and local locking prevents accidental modification during operation of the LCD screen, requiring a password to unlock after locking.
[0018] like Figure 1-4 As shown in Figure 7, the housing 1 is equipped with a transmitter 4 aviation socket 40, several explosion-proof glands 2, and several aviation plugs 3 with connecting wires 31. The transmitter 4 is screwed onto the transmitter 4 aviation socket 40. Through the screw connection, a quick-connect connection is formed between the transmitter 4 and the power failure instrument host. The several explosion-proof glands 2 are used for intrinsically safe transmission between external signals and signals inside the housing 1. The quick-connect design of the transmitter 4 to the power failure instrument host allows the transmitter 4 to be connected to the power failure instrument host through a quick-connect direct connection, which is conducive to the rapid replacement of the transmitter 4 on site. This also avoids the situation where existing devices used for power outage detectors require bolts to fix the main unit, cables, and sensors during on-site installation. In contrast, this invention uses a quick-connect connection between the main unit and the transmitter 4, eliminating the need for cables and simplifying the installation and use of the power outage detector. Among the several explosion-proof gland 2 options, the preferred option is to use a stuffing box type explosion-proof cable clamping and sealing joint for the several explosion-proof gland 2. At the same time, the explosion-proof cable clamping and sealing joint will include an O-ring. That is, the connection between the stuffing box type explosion-proof cable clamping and sealing joint and the explosion-proof cable on the enclosure 1 can be formed by the O-ring and the compression connection between the explosion-proof cable and the stuffing box type explosion-proof cable clamping and sealing joint, thus forming a sealed connection between the explosion-proof cable and the enclosure 1, and constituting waterproof, dustproof and explosion-proof for the connection of the explosion-proof cable to the enclosure 1.
[0019] like Figure 1-3 As shown in Figures 8-9, a window 11 is provided on the housing 1 in the area corresponding to the LCD screen. A protective component 6 is provided between the window 11 and the LCD screen. In a preferred embodiment, the protective component 6 includes tempered glass 63 distributed on one side of the LCD screen, a glass fixing frame 62 fitted over the tempered glass 63, and a glass pressure plate 64 distributed between the LCD screen and the tempered glass 63. Silicone pads 64 are respectively provided between the tempered glass 63 and the glass pressure plate 64, and on the side of the tempered glass 63 away from the glass pressure plate 64. The protective component 6 is limited to the inner top surface of the housing 1 by the side of the glass fixing frame 62 away from the glass pressure plate 64, thereby improving the reliability of the protection of this utility model. That is, it avoids the situation where the reliability of the entire power-off device motor is affected by unreliable protection after replacing the existing commonly used digital tube with an LCD screen.
