Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, and in particular to a gas monitoring device. Background Technology

[0002] Gas is a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. Residents mostly use natural gas as fuel for cooking, boiling water, heating, etc.

[0003] Gas is flammable and explosive, so extra caution is required during use. After use, valves and switches should be turned off promptly, and pipelines, especially hoses, should be inspected regularly to prevent gas leaks.

[0004] Most gas accidents that occur today are caused by residents forgetting to turn off valves or switches after using gas. As time goes by, the gas content in the air continues to increase, eventually leading to an explosion.

[0005] Existing gas monitoring devices are usually unable to prevent gas leaks, and because they are typically located close to the gas source, their surfaces often become covered with oil stains after long-term use, affecting the normal operation of the equipment.

[0006] Therefore, this application provides a gas monitoring device to overcome the shortcomings of the prior art. Utility Model Content

[0007] The purpose of this invention is to solve the problem that existing equipment usually cannot prevent gas leaks and that oil stains on the equipment surface affect the normal operation of the equipment.

A stop block is also fixed inside the connecting pipe, and a connecting hole is provided in the stop block, the connecting hole penetrating the stop block.

[0012] As a preferred technical solution, the connecting hole consists of two parts: a circular hole and a frustum-shaped hole. The frustum-shaped hole is located on the side of the circular hole closer to the baffle. The diameter of the frustum-shaped hole is larger the closer it is to the baffle. The circular hole and the frustum-shaped hole are connected.

[0013] As a preferred technical solution, the blocking mechanism includes a sliding rod, which is slidably connected to a baffle. A magnetic block is fixed to the side of the sliding rod near the baffle. The magnetic block is frustum-shaped, with a smaller diameter on the side near the baffle.

[0024] Example 1

[0025] As attached Figure 1 To be continued Figure 5 As shown: A gas monitoring device includes a monitoring mechanism 1 and a connecting pipe 2. The connecting pipe 2 is equipped with a sealing mechanism 3 and a gas flow meter 4. The gas flow meter 4 is used to measure the amount of gas used. The sealing mechanism 3 is electrically connected to the monitoring mechanism 1. The monitoring mechanism 1 is also electrically connected to a plug that can be electrically connected to a socket. This is prior art, and the specific structure will not be described in detail.

[0026] like Figures 1 to 3As shown: The monitoring mechanism 1 includes a base plate 101, with ear plates 102 fixed to the side wall of the base plate 101. Mounting holes 103 are provided on the ear plates 102. A cylindrical connecting plate 104 is fixed to the base plate 101. A main control board 105, a second connecting plate 106, a third connecting plate 108, and an alarm device 110 are also fixed to the base plate 101. A gas sensor 107 is installed in the second connecting plate 106, and a buzzer 109 is installed in the third connecting plate 108. The alarm device 110 has a light strip 111 that can change color. The main control board 105 is electrically connected to the alarm device 110, the buzzer 109, and the gas sensor 107. Under normal circumstances, the light strip 111 displays the first color. When the gas sensor 107 detects excessive gas content in the air, the gas sensor 107 transmits the information. The information is transmitted to the main control board 105, which then transmits it to the alarm 110 and the buzzer 109. The light strip 111 in the alarm 110 displays a different color, and at the same time, the buzzer 109 sounds an alarm. The main control board 105 also transmits information to the user's mobile phone to promptly remind the user to check. The main control board 105 can also receive information from the mobile phone and make corresponding instructions based on the information. The outer wall of the connecting plate 104 is provided with external threads and also includes a cover 112. The cover 112 has a slot 113, and the alarm 110 is slidably connected to the slot 113. The cover 112 also has several slots 114, and the cover 112 is threadedly connected to the connecting plate 104, making it convenient for the user to remove the cover 112 for cleaning and preventing oil stains from clogging the slots 114 and affecting the normal use of the equipment.

[0027] like Figure 1 , Figure 4 , Figure 5 As shown: A baffle 201 is fixed inside the connecting pipe 2. Several through holes 202 are opened on the baffle 201. A block 203 is also fixed inside the connecting pipe 2. A connecting hole 204 is opened in the block 203. The connecting hole 204 passes through the block 203. The connecting hole 204 consists of two parts: a round hole and a frustum-shaped hole. The frustum-shaped hole is located on the side of the round hole close to the baffle 201. The diameter of the frustum-shaped hole is larger the closer it is to the baffle 201. The round hole and the frustum-shaped hole are connected. Alternatively, a trumpet-shaped hole can be used instead of the frustum-shaped hole.

[0028] like Figure 1 , Figure 4 , Figure 5As shown: The sealing mechanism 3 includes a slide rod 301, which is slidably connected to a baffle 201. A magnetic block 302 is fixed to the side of the slide rod 301 near the stop 203. The magnetic block 302 is frustoconical, with a smaller diameter on the side near the stop 203. A baffle 2 303 is fixed to the outer wall of the slide rod 301, located on the side of the baffle 201 near the stop 203. A sleeve 304 is fixed to the side of the baffle 201 near the stop 203, and the sleeve 304 is slidably connected to the slide rod 301. A spring 305 is wound around the outer wall of 301. The spring 305 and the second baffle 303 are both located in the first sleeve 304. One end of the spring 305 is connected to the second baffle 303 and the other end is connected to the first sleeve 304. The second sleeve 306 is also included. The second sleeve 306 is installed on the outer wall of the connecting pipe 2. The second sleeve 306 and the connecting pipe 2 form a space. An electromagnet 307 is provided in the space. The electromagnet 307 is electrically connected to the monitoring mechanism 1. When energized, it generates the same magnetism as the magnetic block 302, which pushes the magnetic block 302 to move.

[0029] Operating procedure: First, install the connecting pipe 2 in the pipeline. After installation, open the valve and spray soapy water at the connection point. Observe whether bubbles appear. If there are no bubbles, it proves that there is no air leakage. Fix the monitoring mechanism 1 within 1.5m of the air source and install it 0.3~1.5m below the ceiling. During installation, use bolts to pass through the mounting hole 103 to fix it. Tighten the cover 112. Then, connect the monitoring mechanism 1 to the socket and connect the monitoring mechanism 1 to the electromagnet 307. When it is necessary to clean the monitoring mechanism 1, simply unscrew the cover 112. After cleaning, screw the cover 112 back on. It is simple and easy to operate.

[0030] When the gas sensor 107 detects a normal gas content in the air, the LED strip 111 displays a normal color, and neither the buzzer 109 nor the electromagnet 307 operates. When the gas sensor 107 detects a gas content higher than normal, it transmits an abnormal signal to the main control board 105. The main control board 105 issues a command, the LED strip 111 changes color, the buzzer 109 sounds an alarm, and simultaneously, the electromagnet 307 operates, pushing the magnetic block 302 towards the baffle 201 until the magnetic block 302 blocks the through hole 202. The magnetic block 302 can no longer move towards the baffle 201, and the automatic... When the gas is turned off, the main control board 105 transmits information to the user's mobile phone, reminding the user to check in time. After the user completes the check and confirms that the abnormality has been eliminated, the main control board 105 receives the signal, converts the signal and sends a command. The color of the light strip 111 returns to normal, the buzzer 109 stops sounding the alarm, and at the same time, the electromagnet 307 stops working. Under the action of the spring 305, the magnetic block 302 disengages from the stop block 203. The spring 305 drives the magnetic block 302 to move towards the side of the baffle 201 until it returns to its original state, and it can be used again.
