Description

Technical Field

[0001] This utility model relates to the field of gas safety technology, specifically a gas leak linkage cut-off device. Background Technology

[0002] Gas is widely used as a common energy source in daily life and industrial production. However, gas leaks can cause serious fires and explosions, posing a serious threat to people's lives and property. In order to effectively deal with the gas leak problem, various gas leak alarm devices and shut-off devices have appeared on the market. These devices detect the gas concentration and can issue an alarm signal and cut off the gas supply in a timely manner when a gas leak is detected, thereby preventing accidents from happening.

[0003] Currently available gas leak shut-off devices typically only have a single shut-off function. When a gas leak occurs, although they can cut off the gas supply, users often cannot intuitively understand the device's working status or whether the gas has been cut off. Furthermore, existing devices lack necessary reminders and instructions during the handling of gas leaks, which may cause users to feel confused and uneasy when dealing with gas leaks.

[0004] To address the aforementioned problems, this utility model proposes a gas leak linkage cut-off device that can intuitively display the working status and provide reminder and indication functions. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a gas leak linkage shut-off device. The technical solution adopted is as follows: a valve body is included, the sides of both ends of the valve body are fixedly connected to the sides of one end of two fixed plates, the top of the two fixed plates are fixedly connected to the bottom of the outer shell, the valve stem on the valve body extends through the through hole at the bottom of the outer shell to the inside of the outer shell, a protective cover is fixedly installed on the side of the outer shell, the protective cover communicates with the inside of the outer shell, a control module is fixedly installed at the bottom of the inner shell, a rotating seat is fixedly installed in the middle of the bottom of the inner shell, the side of the rotating seat is rotatably connected to the inner side of the rotating seat, a motor is fixedly installed at the top of the inner shell, the output shaft of the motor is fixedly connected to one end of the rotating rod, the other end of the rotating rod is fixedly connected to the upper end of the valve stem on the valve body, a wireless receiving module is fixedly installed at the bottom of the inner shell, the motor and the wireless receiving module are electrically connected to the control module, and a flip reminder mechanism is installed inside the valve body and the protective cover.

[0006] The flip-up reminder mechanism includes a pulley, a fixed base, a transmission gear, a drive gear, a belt, a flip plate, and markings. The fixed base is fixedly installed on one side of the bottom of the housing. A connecting rod is rotatably installed in the through hole at the upper end of the fixed base. The inner side of the drive gear is fixedly connected to the side of the lower end of the rotating rod. The middle part of the end face of the transmission gear is fixedly connected to one end of the connecting rod. The transmission gear meshes with the drive gear. The other end of the connecting rod is fixedly connected to the middle part of the end face of one of the belts. The middle part of the end face of the other belt is rotatably connected to the side of the protective cover. The two belts are connected by a belt. The side of one end of the flip plate is fixedly connected to the middle part of the end face of the pulley on the protective cover. The side of the other end of the flip plate is rotatably connected to the inner side of the protective cover. Different markings are provided on the two sides of the flip plate.

[0007] In a preferred embodiment of this invention, the number of teeth on the drive gear is twice the number of teeth on the transmission gear.

[0008] In a preferred embodiment of this invention, the protective cover is made of transparent acrylic material. In another preferred embodiment, two colored LEDs of different colors are fixedly installed on the top of the protective cover, and these LEDs are electrically connected to the control module. In yet another preferred embodiment, a gas alarm is fixedly installed on the top of the outer shell, and the gas alarm is electrically connected to the control module.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model uses a motor to drive a rotating rod to rotate, which in turn drives the valve stem on the valve body to rotate. In the event of a gas leak, the valve body can be automatically closed to prevent further gas leakage. When the rotating rod rotates, it drives the drive gear to rotate, which in turn drives the transmission gear to rotate. The transmission gear drives the connecting rod and one of the pulleys to rotate, which in turn drives the belt and another pulley to rotate. This causes the pulley to rotate the flip plate. By observing the flipping state and markings of the flip plate, users can understand the working status of the device and whether the gas has been cut off. This allows users to intuitively understand the gas cut-off status, improving the safety and ease of use of the device.

[0010] 2. The number of teeth on the drive gear is twice that of the transmission gear, allowing the drive gear to rotate 90 degrees. When the valve body is closed, the transmission gear can rotate 180 degrees, driving the flip plate to flip accurately. The protective cover is made of transparent acrylic material, allowing users to clearly see the status of the flip plate, further enhancing the device's reminder and indication functions.

[0011] 3. Different colored LED beads can emit different colored lights to provide visual reminders and indications. Through the gas alarm, this gas leak linkage shut-off device can not only be used in conjunction with other gas detection equipment, but also detect gas on its own, so as to cut off the gas pipeline in time when a gas leak occurs.

Detailed Implementation

[0019] Example 1

[0020] like Figures 1 to 6As shown, this utility model discloses a gas leak linkage shut-off device. The technical solution includes a valve body 1, with the sides of both ends of the valve body 1 fixedly connected to the sides of one end of two fixing plates 2. The tops of the two fixing plates 2 are fixedly connected to the bottom of a housing 3. A valve stem on the valve body 1 extends through a through hole at the bottom of the housing 3 into the interior of the housing 3. A protective cover 4 is fixedly installed on the side of the housing 3, and a gas alarm 11 is fixedly installed on the top of the housing 3. The gas alarm 11 is electrically connected to a control module 5. Through the gas alarm, this gas leak linkage shut-off device can not only be used in conjunction with other gas detection equipment but also detect gas itself, thus enabling timely shut-off of the gas pipeline in case of a gas leak. The protective cover 4 connects to the interior of the housing 3 and is made of transparent acrylic material, allowing the user to clearly see the state of the flip plate 96. The device's reminder and indication functions are further enhanced. Two colored LED beads 10 are fixedly installed at the top inside the protective cover 4. The two colored LED beads 10 are different colors and are electrically connected to the control module 5. Different colored LED beads 10 can emit different colored lights to provide visual reminders and indications. The control module 5 is fixedly installed at the bottom inside the outer shell 3. A rotating seat 6 is fixedly installed in the middle of the bottom inside the outer shell 3. The side of the rotating seat 6 is rotatably connected to the inner side of the rotating seat 6. A motor 7 is fixedly installed at the top inside the outer shell 3. The output shaft of the motor 7 is fixedly connected to one end of the rotating rod 8. The other end of the rotating rod 8 is fixedly connected to the upper end of the valve stem on the valve body 1. A wireless receiving module 13 is fixedly installed at the bottom inside the outer shell 3. The motor 7 and the wireless receiving module 13 are electrically connected to the control module 5. A flip reminder mechanism 9 is installed inside the valve body 1 and the protective cover 4.

[0021] The working principle of a gas alarm is as follows: A gas alarm detects gas leaks through its internal gas sensors. These sensors are highly sensitive and selective, capable of detecting specific types of gas, such as natural gas, manufactured gas, or liquefied petroleum gas. Common sensor types include semiconductor, catalytic combustion, and infrared optical types. When these sensors come into contact with gas, their resistance changes with the gas concentration. When the gas concentration detected by the gas sensor exceeds a preset safety level, the alarm system immediately activates and transmits a wireless signal to alert the user of the gas leak.

[0022] The flipping reminder mechanism 9 includes a pulley 91, a fixed base 92, a transmission gear 93, a drive gear 94, a belt 95, a flipping plate 96, and an indicator 97. The fixed base 92 is fixedly installed on one side of the bottom inside the housing 3. A connecting rod 12 is rotatably installed in the through hole at the upper end of the fixed base 92. The inner side of the drive gear 94 is fixedly connected to the side of the lower end of the rotating rod 8. The middle part of the end face of the transmission gear 93 is fixedly connected to one end of the connecting rod 12. The transmission gear 93 meshes with the drive gear 94. The number of teeth on the drive gear 94 is twice the number of teeth on the transmission gear 93. This double number of teeth on the drive gear 94 allows the drive gear 94 to rotate 90 degrees. When the valve body 1 is closed, the transmission gear 93 can rotate 180 degrees, causing the flipping plate 96 to flip accurately. The other end of the connecting rod 12 is fixedly connected to the middle part of the end face of one of the belts 95. The middle part of the end face of the other belt 95 is rotatably connected to the side of the protective cover 4. The two belts 95 are connected by a belt 95. Next, one side of the flip plate 96 is fixedly connected to the middle of the end face of the pulley 91 on the protective cover 4, and the other side of the flip plate 96 is rotatably connected to the inner side of the protective cover 4. Different markings 97 are provided on the two sides of the flip plate 96. The motor 7 drives the rotating rod 8 to rotate, which in turn drives the valve stem on the valve body 1 to rotate. In the event of a gas leak, the valve body 1 can be automatically closed to prevent further gas leakage. When the rotating rod 8 rotates, it drives the drive gear 94 to rotate, which in turn drives the transmission gear 93 to rotate. The transmission gear 93 drives the connecting rod 12 and one of the pulleys 91 to rotate, which in turn drives the belt 95 and the other pulley 91 to rotate, which in turn drives the flip plate 96 to flip. By observing the flip state of the flip plate 96 and the markings 97, the user can understand the working status of the device and whether the gas has been cut off. This allows the user to intuitively understand the gas cut-off status, improving the safety and ease of use of the device.

[0023] The working principle of this utility model is as follows: During installation, the valve body 1 is installed on the gas pipeline and connected to an external power source. In use, the wireless receiver module 13 can be wirelessly connected to an external gas leak detection device. When a gas leak occurs, the external gas leak detection device or gas alarm 11 detects the leak, and the control module 5 automatically controls the motor 7 to operate. This causes the output shaft of the motor 7 to drive the rotating rod 8 to rotate, which in turn causes the valve stem on the valve body 1 to rotate 90 degrees, closing the valve body 1 and cutting off the gas pipeline. As the rotating rod 8 rotates, it drives the drive gear 94 to rotate, which in turn drives the transmission gear 93 to rotate. The transmission gear 93 then drives the connecting rod 12 and one of the pulleys 91 to rotate, which in turn drives the belt 95 to rotate, which in turn drives the other pulley 91 to rotate. The other pulley 91 drives the flip plate 96 to rotate. Since the number of teeth on the drive gear 94 is twice the number of teeth on the transmission gear 93, when the rotating rod 8 drives the drive gear 94 to rotate 90 degrees, the drive gear 94 will drive the transmission gear 93 to rotate 180 degrees. This causes the transmission gear 93 to drive the pulley 91 and the flip plate 96 to rotate 180 degrees, causing the closing indicator 97 on the flip plate 96 to flip to the outside, making it easy for people to see the indicator 97 through the transparent protective cover 4. When the valve body 1 is closed, the control module 5 will automatically control one of the colored LED beads 10 to work, so that the colored LED bead 10 emits a red light to remind people that the valve body 1 is closed and the gas pipeline has been cut off. Conversely, when the valve is normally open, the control module 5 will control the other colored LED bead 10 to emit a green light to remind people that the pipeline is connected.

[0024] It is worth noting that the valve body 1 described in this utility model is a common ball valve body, which is existing technology. Its working principle is well known to those skilled in the art, and will not be described here.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
