Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, and in particular to a maintenance-free gas meter equipped with an automatic cleaning function. Background Technology

[0002] Most gas meters on the market currently use LCD screens to display data. However, over time, these screens are prone to becoming blurry due to the accumulation of dust, oil, moisture, and other debris, affecting data readability. Traditional cleaning methods rely on manual wiping, which requires frequent user intervention and is inconvenient. This is especially true for gas meters installed in high or concealed locations, where cleaning is more difficult. Some users neglect cleaning and maintenance, leaving the screen blurry for extended periods. This can lead to reading errors and even equipment malfunctions. Furthermore, some gas meters equipped with automatic cleaning functions lack real-time monitoring mechanisms for the cleaning function's operation. If the electrical components used for the cleaning function fail, users may not notice in time, and the absence of fault warnings prevents proactive alerts when malfunctions occur, ultimately causing the cleaning function to fail. Utility Model Content

[0003] This utility model relates to a maintenance-free gas meter equipped with an automatic cleaning function, which solves the problems of current gas meter LCD screens being prone to blurry display due to debris accumulation, the inconvenience of traditional manual cleaning, user neglect leading to reading errors or malfunctions, and the lack of operating status monitoring and fault warning in some gas meters with automatic cleaning functions, resulting in the failure of the cleaning function.

[0004] This utility model provides a maintenance-free gas meter with an automatic cleaning function, specifically including: a gas meter, a mounting plate fixedly installed on the front side of the top end of the gas meter housing, and a set of motors fixedly installed on the rear end of the mounting plate; a cleaning plate provided on the front side of the mounting plate, a connecting shaft fixedly installed on the right end of the cleaning plate, the rotating shaft end of the motor passing through the mounting plate and fixedly connected to the connecting shaft; a limiting slot opened on the rear end of the cleaning plate, the limiting slot passing through the left end of the cleaning plate; a plug-in plate provided on the rear side of the cleaning plate, a limiting plug fixedly installed on the front end of the plug-in plate, the limiting plug slidingly engaging with the limiting slot; and a cleaning and wiping layer fixedly adhered to the rear end of the plug-in plate.

[0005] Furthermore, the limiting slot has an isosceles trapezoidal groove structure; the limiting block has an isosceles trapezoidal block structure, and the size of the limiting block structure matches the size of the limiting slot structure; a locking slot with a circular groove structure is provided on the left side of the front end face of the limiting block.

[0006] Furthermore, a limiting insertion hole is provided on the left side of the front end face of the cleaning plate. The limiting insertion hole is a round hole that passes through the limiting slot. A limiting pin is inserted into the limiting insertion hole. A pull plate is fixedly installed on the front end face of the limiting pin. The rear end face of the pull plate is fixedly connected to the front end face of the cleaning plate by a return spring.

[0007] Furthermore, when the limiting plug and the limiting slot are slidably engaged, the limiting hole and the locking slot are coaxial; when the reset spring is in its natural state, the rear end of the limiting plug is engaged inside the locking slot.

[0008] Furthermore, a control housing is installed on the rear end face of the mounting plate, and the control housing is connected to the gas meter via the same power supply line; the control housing contains a microcontroller and a cleaning timer module electrically connected to it, and the timer value of the cleaning timer module is 24 hours; a USB data transmission port is embedded in the right end face of the control housing, and the USB data transmission port is electrically connected to the microcontroller; the motor is electrically connected to the microcontroller; when the motor is not running, the cleaning plate is in a position that does not obstruct the gas meter's LCD display screen.

[0009] Furthermore, when the timing value of the cleaning timing module is reached, the cleaning timing module sends a feedback signal to the microcontroller, which controls the motor shaft to rotate one revolution. During the process of the motor shaft synchronously driving the cleaning plate to rotate one revolution, the cleaning wiping layer comes into contact with the liquid crystal display screen of the gas meter.

[0010] Furthermore, a sensing slot is provided on the right side of the front end face of the mounting plate, and an operating status monitoring sensing component for proximity switches is installed inside the sensing slot. The operating status monitoring sensing component is electrically connected to the microcontroller. An operating status fault warning component for buzzers is installed on the top face of the control housing, and the operating status fault warning component is electrically connected to the microcontroller.

[0011] Furthermore, a mating disc is fixedly installed on the outer circumference of the connecting shaft. A sensing insert is embedded between the front and rear faces of the mating disc, with the sensing insert facing the cleaning plate. When the motor shaft synchronously drives the cleaning plate to rotate one revolution, the sensing insert can move into the sensing range of the operation status monitoring sensing component during rotation. The control housing also has an operation status monitoring timing module, which is electrically connected to the microcontroller. The timing value of the operation status monitoring timing module is one second longer than the time it takes for the motor shaft to rotate one revolution. When the timing value of the cleaning timing module is reached, the cleaning timing module sends a feedback signal to the microcontroller, and the microcontroller also controls the operation status monitoring timing module to start. When the operation status monitoring sensing component senses the sensing insert, it sends a feedback signal to the microcontroller, and the microcontroller controls the operation status monitoring timing module to shut down. When the timing value of the operation status monitoring timing module is reached, it sends a feedback signal to the microcontroller, and the microcontroller controls the operation status fault warning component to start.

[0012] This utility model provides a maintenance-free gas meter equipped with an automatic cleaning function, which has the following beneficial effects:

[0013] When the gas meter of this utility model is powered on, the cleaning timer module starts simultaneously. After the timer value is reached, the microcontroller controls the motor to drive the cleaning plate to rotate, and the cleaning wiping layer contacts and wipes the LCD screen, realizing automatic cleaning of the gas meter's LCD screen without manual operation, thus improving the convenience of use.

[0014] This invention can monitor the operating status and provide fault warnings. When the motor rotates, it will synchronously drive the disc and the sensing block to rotate. When the sensing block enters the sensing range of the operating status monitoring sensing component, the component feeds back a signal to the microcontroller to shut down the operating status monitoring timing module. If the motor fails to drive the cleaning plate to rotate, the timing module will feed back a signal after reaching the timing value, and the microcontroller will start the buzzer to provide a fault warning, which will facilitate timely maintenance and ensure the normal operation of the equipment.

[0015] This utility model allows for easy disassembly and installation of the cleaning wipe layer. When the gripping pull plate is pulled outward, the return spring extends, the limiting pin disengages from the locking slot, and the limiting fixation on the plug plate is released. Through the sliding engagement of the limiting block and the limiting slot, the plug plate can slide along the limiting slot, realizing the disassembly and separation of the cleaning wipe layer and the cleaning plate for convenient individual cleaning. At the same time, the limiting engagement of the limiting pin and the locking slot, and the limiting engagement of the limiting block and the limiting slot, ensures that the cleaning wipe layer will not move during cleaning, thus guaranteeing the cleaning effect.

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example: Please refer to Figures 1 to 7 :

[0030] This utility model proposes a maintenance-free gas meter with an automatic cleaning function, comprising: a gas meter 1, a mounting plate 101 fixedly installed on the front side of the top end of the gas meter 1 housing, a set of motors 103 fixedly installed on the rear end of the mounting plate 101; a cleaning plate 2 is provided on the front side of the mounting plate 101, a connecting shaft 201 is fixedly installed on the right end of the cleaning plate 2, the shaft end of the motor 103 passes through the mounting plate 101 and is fixedly connected to the connecting shaft 201; a limiting slot 206 is provided on the rear end of the cleaning plate 2, the limiting slot 206 passes through the left end of the cleaning plate 2; a plug-in plate 401 is provided on the rear side of the cleaning plate 2, a limiting plug 402 is fixedly installed on the front end of the plug-in plate 401, the limiting plug 402 slides into the limiting slot 206; a cleaning and wiping layer 4 is fixedly adhered to the rear end of the plug-in plate 401; the limiting slot 206 has an isosceles trapezoidal groove structure; The limiting block 402 has an isosceles trapezoidal block structure, and its structural dimensions match those of the limiting slot 206. A locking slot 403 with a circular groove structure is provided on the left side of the front end face of the limiting block 402. A limiting hole 202, which is a circular hole, is provided on the left side of the front end face of the cleaning plate 2, and it passes through the limiting slot 206. A limiting post 205 is inserted into the limiting hole 202, and a pull plate 204 is fixedly installed on the front end face of the limiting post 205. The rear end face of the pull plate 204 is fixedly connected to the front end face of the cleaning plate 2 via a return spring 203. When the limiting block 402 and the limiting slot 206 are slidably engaged, the limiting hole 202 and the locking slot 403 are coaxial. When the return spring 203 is in its natural state, the rear end of the limiting post 205 is limited and inserted into the locking slot 403.

[0031] The mounting plate 101 has a control housing 102 installed on its rear end, which shares the same power supply line as the gas meter 1. The control housing 102 contains a microcontroller 1010 and a cleaning timer module 108 electrically connected to it, with a timer value of 24 hours. A USB data transmission port 105 is embedded in the right end of the control housing 102 and is electrically connected to the microcontroller 1010. A motor 103 is electrically connected to the microcontroller 1010. When the motor 103 is not running, the cleaning plate 2 is positioned so as not to obstruct the LCD display of the gas meter 1. When the timer value of the cleaning timer module 108 is reached, the cleaning timer module 108 sends a feedback signal to the microcontroller 1010, which then controls the shaft of the motor 103 to rotate one revolution. During the rotation of the cleaning plate 2, the cleaning wiping layer 4 comes into contact with the LCD display of the gas meter 1.

[0032] The mounting plate 101 has a sensing slot 106 on the right side of its front end face. A proximity switch-based operating status monitoring sensing component 107 is installed inside the sensing slot 106 and is electrically connected to the microcontroller 1010. A buzzer-based operating status fault warning component 104 is installed on the top surface of the control housing 102 and is also electrically connected to the microcontroller 1010. A mating disc 3 is fixedly mounted on the outer circumference of the connecting shaft 201. A sensing insert 301 is embedded between the front and rear ends of the mating disc 3, with the sensing insert 301 facing the cleaning plate 2. When the motor 103's shaft synchronously rotates the cleaning plate 2 one revolution, the sensing insert 301 can move into the sensing range of the operating status monitoring sensing component 107 during rotation. The control housing 102 also contains an operating status monitoring... The timing module 109 and the operation status monitoring timing module 109 are electrically connected to the microcontroller 1010. The timing value of the operation status monitoring timing module 109 is one second longer than the time it takes for the end of the motor 103 shaft to rotate one revolution. When the timing value of the cleaning timing module 108 is reached, the cleaning timing module 108 sends a feedback signal to the microcontroller 1010, and the microcontroller 1010 also controls the operation status monitoring timing module 109 to start. When the operation status monitoring sensing component 107 senses the sensing insert 301, the operation status monitoring sensing component 107 sends a feedback signal to the microcontroller 1010, and the microcontroller 1010 controls the operation status monitoring timing module 109 to turn off. When the timing value of the operation status monitoring timing module 109 is reached, the operation status monitoring timing module 109 sends a feedback signal to the microcontroller 1010, and the microcontroller 1010 controls the operation status fault warning component 104 to start.

[0033] The working principle of this embodiment:

[0034] Since the control housing 102 and the gas meter 1 are connected to the same power supply line, when the gas meter 1 is powered on and started, the cleaning timer module 108 is started accordingly. When the timer value of the cleaning timer module 108 is reached, the cleaning timer module 108 sends a feedback signal to the microcontroller 1010. The microcontroller 1010 controls the shaft end of the motor 103 to rotate one revolution and simultaneously controls the running status monitoring timer module 109 to start.

[0035] When the microcontroller 1010 controls the shaft end of the motor 103 to rotate one revolution, the shaft end of the motor 103 synchronously drives the cleaning plate 2 to rotate. During the rotation, the cleaning wiping layer 4 will come into contact with the LCD screen of the gas meter 1, thereby wiping and cleaning the LCD screen of the gas meter 1 to achieve automatic cleaning.

[0036] As the disc 3 rotates along with the connecting shaft 201, the sensing block 301 will move into the sensing range of the operating status monitoring sensing component 107. When the operating status monitoring sensing component 107 senses the sensing block 301, it sends a feedback signal to the microcontroller 1010. The microcontroller 1010 then controls the operating status monitoring timing module 109 to shut down. If the motor 103 malfunctions and cannot drive the cleaning plate 2 to rotate for wiping, it cannot sense and shut down the operating status monitoring timing module 109 through the cooperation of the operating status monitoring sensing component 107 and the sensing block 301. When the timing value of the operating status monitoring timing module 109 is reached, it sends a feedback signal to the microcontroller 1010. The microcontroller 1010 then activates the operating status fault warning component 104 for the buzzer, which sounds at a high decibel to warn of the malfunction and facilitate timely repair.

[0037] When the cleaning wipe layer 4 needs to be cleaned, the pull plate 204 can be squeezed and pulled outward. At this time, the return spring 203 is pulled and extended, and the limiting plug 205 will move along the limiting plug hole 202. Simultaneously, the limiting plug 205 will disengage from the locking slot 403, releasing the limiting fixation of the plug plate 401. At this time, the plug plate 401 can slide along the limiting slot 206 through the sliding insertion engagement of the limiting plug 402 and the limiting slot 206, thereby realizing the disassembly and separation of the cleaning wipe layer 4 and the cleaning plate 2, so as to clean the cleaning wipe layer 4 separately. Furthermore, through the limiting insertion engagement of the limiting plug 205 and the locking slot 403 and the limiting insertion engagement of the limiting plug 402 and the limiting slot 206, it is ensured that the cleaning wipe layer 4 will not move when wiping and cleaning the LCD screen of the gas meter 1.
