Description

Technical Field

[0001] This application relates to the field of gas safety technology, and more specifically, to a gas safety monitoring device. Background Technology

[0002] Gas is a commonly used fuel gas, including natural gas, liquefied petroleum gas, and coal gas. It is widely used in household cooking, heating, hot water supply, industrial production, and power generation. To ensure safe use, it is necessary to maintain good ventilation for gas appliances, regularly inspect pipes and equipment to prevent leaks, and avoid switching on or off electrical appliances during leaks to prevent fires, explosions, or poisoning accidents. Currently, solenoid valves are usually installed when gas enters a home to cut off the gas supply in emergencies, and gas leak alarms are also provided to alert users when leaks occur. However, when users are not at home, the gas concentration near gas pipes may be too high due to the lack of indoor ventilation devices, which still poses a safety hazard. Summary of the Invention

[0003] The purpose of this application is to provide a gas safety monitoring device that can solve the technical problem that when users are not at home, the gas concentration near the gas pipeline may be too high due to the lack of indoor gas dissipation devices, which still poses a safety hazard.

[0004] This application provides a gas safety monitoring device, including a mounting box with an internal solenoid valve. Both ends of the solenoid valve are connected to gas pipelines. A gas alarm is installed at the top of the mounting box. A through hole is opened at the top of the mounting box. An installation pipe is connected to one side of the mounting box. A gas dispersion component for dispersing gas is installed inside the installation pipe, and an exhaust pipe connected to the outside is connected to the installation pipe. Vent holes are opened on the other sides of the mounting box. An opening and closing component for opening or closing the vent holes is installed inside the mounting box. The solenoid valve, the gas dispersion component, and the opening and closing component are all electrically connected to the gas alarm.

[0005] The air dissipation assembly includes a fan and a first motor. The fan is rotatably mounted inside the mounting tube via a bearing, and the output shaft of the first motor is connected to the fan.

[0006] The opening and closing assembly includes a cover plate, a connecting rod, a screw, a second motor, and a sliding rod. The screw is rotatably mounted on the mounting box via a bearing. The output shaft of the second motor is connected to the screw. The sliding rod is fixedly mounted on the mounting box. The connecting rod is threaded onto the screw and slidably mounted on the sliding rod. The cover plate is fixedly connected to the connecting rod and is movable to open or close the vent.

[0007] The exhaust pipe is provided with a first mounting plate, and the first mounting plate is provided with a filter screen.

[0008] The filter screen is hinged to the first mounting plate, and a cylinder is hinged between the filter screen and the exhaust pipe.

[0009] The mounting tube is fitted with a second mounting plate, which is detachably connected to the side of the mounting box.

[0010] The exhaust pipe is detachably connected to the mounting pipe, and the exhaust pipe is provided with a flexible section.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides a gas safety monitoring device that, through the linkage of "gas source cut-off - active gas dispersion - directional exhaust", can directly blow indoor gas to the outdoors through the exhaust pipe, reducing the gas concentration near the gas pipeline and reducing safety hazards. Moreover, by setting up an opening and closing component, the vent is kept closed when no gas leak occurs, preventing indoor fumes from entering the installation box through the vent. In addition, when a leak occurs at the connection between the solenoid valve and the gas pipeline, the gas in the installation box can be discharged from the normally open vent at the top of the installation box, thereby triggering the gas alarm and ensuring comprehensive gas safety monitoring inside and outside the installation box.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] like Figures 1 to 5 As shown in the figure, this application embodiment provides a gas safety monitoring device, including an installation box 2 with a solenoid valve 1 inside. Both ends of the solenoid valve 1 are connected to gas pipes 3. A gas alarm 4 is installed at the upper end of the installation box 2. A through hole 21 is opened at the top of the installation box 2. An installation pipe 5 is connected to one side of the installation box 2. A gas dispersing component 6 for dispersing gas is installed inside the installation pipe 5. An exhaust pipe 7 connected to the outside is also installed on the installation pipe 5. Ventilation holes 22 are opened on the other sides of the installation box 2. An opening and closing component 8 for opening or closing the ventilation holes 22 is installed inside the installation box 2. The solenoid valve 1, the gas dispersing component 6, and the opening and closing component 8 are all electrically connected to the gas alarm 4.

[0035] When in use, the gas pipes 3 at both ends of the solenoid valve 1 are connected to the outdoor main gas branch pipe and the indoor gas inlet pipe, respectively. The solenoid valve 1 is kept open, and gas is supplied normally through the gas pipes 3. When a gas leak occurs, the gas will trigger the gas alarm 4. The gas alarm 4 will transmit the signal to the external controller. The controller will control the solenoid valve 1 to close immediately and cut off the gas supply. At the same time, the controller will control the gas dispersing component 6 to operate, introduce the indoor gas into the installation box 2, and blow it directly to the outdoors from the exhaust pipe 7. At the same time, the controller will control the opening and closing component 8 to operate, open the vent 22 of the installation box 2, so that the gas can flow into the installation box 2.

[0036] This device, through the linkage of "gas source cut-off - active gas dispersion - directional exhaust", can directly blow indoor gas to the outdoors through exhaust pipe 7, reducing the gas concentration near gas pipeline 3 and reducing safety hazards. Moreover, by setting up opening and closing component 8, the vent 22 is kept closed when no gas leak occurs, preventing indoor fumes from entering the installation box 2 through the vent 22. In addition, when a leak occurs at the connection between solenoid valve 1 and gas pipeline 3, the gas in the installation box 2 can be discharged from the normally open vent 21 at the top of the installation box 2, thereby triggering the gas alarm 4, ensuring comprehensive gas safety monitoring inside and outside the installation box 2.

[0037] like Figure 1 and 2 As shown, in this embodiment, the air dissipation assembly 6 includes a fan 61 and a first motor 62. The fan 61 is rotatably mounted in the mounting tube 5 via a bearing, and the output shaft of the first motor 62 is connected to the fan 61.

[0038] When in use, the first motor 62 is turned on to drive the fan 61 to rotate, forming an axial airflow in the mounting pipe 5, which introduces the indoor gas into the mounting box 2 and blows it directly to the outside from the exhaust pipe 7.

[0039] like Figures 1 to 3 As shown, in this embodiment, the opening and closing assembly 8 includes a cover plate 81, a connecting rod 82, a screw 83, a second motor 84, and a sliding rod 85. The screw 83 is rotatably mounted on the mounting box 2 via a bearing. The output shaft of the second motor 84 is connected to the screw 83. The sliding rod 85 is fixedly mounted on the mounting box 2. The connecting rod 82 is threaded onto the screw 83 and slidably mounted onto the sliding rod 85. The cover plate 81 is fixedly connected to the connecting rod 82, and the cover plate 81 can be moved to open or close the vent hole 22.

[0040] When in use, the second motor 84 is turned on to drive the screw 83 to rotate. The screw 83 drives the connecting rod 82 to move. The cover plate 81 moves with the connecting rod 82 to open the vent 22 of the mounting box 2, so that the gas can flow into the mounting box 2. The connecting rod 82 and the slide rod 85 work together to guide and limit the cover plate 81.

[0041] like Figure 4 and 5 As shown, in this embodiment, a first mounting plate 71 is provided inside the exhaust pipe 7, and a filter screen 72 is provided on the first mounting plate 71; the filter screen 72 can intercept large particles or birds from entering the room from the exhaust pipe 7, and can not affect the normal exhaust when gas leaks.

[0042] like Figure 4 and 5 As shown, in this embodiment, the filter screen 72 is hinged to the first mounting plate 71, and a cylinder 73 is hinged between the filter screen 72 and the exhaust pipe 7. When a gas leak occurs, the controller controls the cylinder 73 to open, and the cylinder 73 retracts to drive the filter screen 72 to rotate to open the exhaust pipe 7, thereby reducing the influence of the filter screen 72 on the ventilation of the exhaust pipe 7, increasing the exhaust volume, and facilitating the rapid exhaust of gas.

[0043] like Figure 1 and 2 As shown, in this embodiment, a second mounting plate 51 is sleeved on the mounting tube 5, and the second mounting plate 51 is detachably connected to the side of the mounting box 2; the second mounting plate 51 is connected to the mounting box 2 by bolts, and the second mounting plate 51 together with the mounting tube 5 can be removed from the mounting box 2, which facilitates the inspection and maintenance of the inside of the mounting box 2 and improves the ease of use.

[0044] In this embodiment, the exhaust pipe 7 and the mounting pipe 5 are detachably connected, and the exhaust pipe 7 is provided with a flexible section; the exhaust pipe 7 and the mounting pipe 5 are connected by threads, and the exhaust pipe 7 can be removed from the mounting pipe 5, which facilitates the maintenance of the air dissipation component 6 inside the mounting pipe 5 and improves the ease of use. The flexible section of the exhaust pipe 7 can be bent, which facilitates avoidance during disassembly and maintenance.

[0045] Working principle: When the gas safety monitoring device provided in this application is in use, the gas pipelines 3 at both ends of the solenoid valve 1 are connected to the outdoor gas main branch pipe and the indoor gas inlet pipe, respectively. The solenoid valve 1 is kept open, and gas is supplied normally through the gas pipeline 3. When a gas leak occurs, the gas will trigger the gas alarm 4. The gas alarm 4 transmits the signal to the external controller, which controls the solenoid valve 1 to close immediately, cutting off the gas supply. At the same time, the controller controls the first motor 62 to turn on. The first motor 62 drives the fan 61 to rotate, forming an axial airflow in the installation pipe 5, which introduces the indoor gas into the installation box 2 and blows it directly to the outside from the exhaust pipe 7. At the same time, the controller controls the second motor 84 to turn on. The second motor 84 drives the screw 83 to rotate. The screw 83 drives the connecting rod 82 to move. The cover plate 81 moves with the connecting rod 82 to open the vent 22 of the installation box 2, so that gas can flow into the installation box 2.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
