Description

Technical Field

[0001] The present invention relates to the technical field of indoor gas safety pressure detection, and in particular to an indoor gas safety pressure detection device based on intelligence. Background Art

[0002] Gas is a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. Gas is transported to households through gas pipelines for users to use. In order to ensure the safety of gas use, it is necessary to conduct safety inspections on gas pipelines. In the prior art, when performing pressure inspections on gas pipelines, electromagnetic pressure gauges are usually installed on the gas pipelines to detect the pressure conditions in the gas pipelines. However, since the electromagnetic pressure gauges require electricity to work, they cannot detect the pressure conditions in the gas pipelines during power outages. Moreover, the electromagnetic pressure gauges may be damaged after long-term use, resulting in inaccurate pressure data, which makes it impossible to ensure the safety of gas use.

[0003] Therefore, a smart gas indoor safety pressure detection device has been developed that can replace the electromagnetic pressure gauge for pressure detection during power outages and can also perform comparative detection with the electromagnetic pressure gauge to ensure the accuracy of pressure data. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] A smart gas indoor safety pressure detection device, such as Figure 1-Figure 10 As shown, it includes a main pipeline 1, a connecting valve 2, a connecting piece 3 and a pressure measuring mechanism 4. The right side of the main pipeline 1 is detachably connected to the connecting valve 2 by six bolts. Six connecting pieces 3 are clamped on the right side of the connecting valve 2. The pressure measuring mechanism 4 is arranged between the connecting pieces 3.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the pressure measuring mechanism 4 includes a connecting pipe 41, a control valve 42, a flow meter 43, an electromagnetic pressure gauge 44, a pressure gauge 45 and a pressure spring 46. The connecting pipe 41 is clamped between the connecting parts 3. The left side of the connecting pipe 41 is closed with the connecting valve 2, and the right side of the connecting pipe 41 is connected to the control valve 42. The upper left side of the connecting pipe 41 is connected to the flow meter 43, and the flow meter 43 is provided with a display screen for displaying values. The upper right side of the connecting pipe 41 is connected to the electromagnetic pressure gauge 44. The middle part of the connecting pipe 41 is slidably connected to a pressure gauge 45, and the pressure gauge 45 is rotatably provided with an indicator needle for indicating the pressure value. The lower part of the pressure gauge 45 is provided with a detection hole for detecting the pressure. A pressure spring 46 is connected between the pressure gauge 45 and the connecting pipe 41.

[0035] When using the present invention, first connect the main pipeline 1 to the gas main, then connect the connecting pipe 41 to the connecting valve 2 through the connecting piece 3, and connect the control valve 42 to the household gas pipeline. When gas is needed, open the connecting valve 2 and the control valve 42, so that the gas is transported to the gas stove through the connecting pipe 41 for use. When the gas flows into the connecting pipe 41, the flow meter 43 monitors the gas flow, and the electromagnetic pressure gauge 44 monitors the pressure in the connecting pipe 41. When a power outage occurs or it is necessary to monitor whether the electromagnetic pressure gauge 44 is accurate, the pressure gauge 45 can be pressed downward, and the pressure spring 46 is squeezed and contracted until the detection hole on the pressure gauge 45 is connected to the connecting pipe 41, so that the pressure gauge 45 detects the pressure in the connecting pipe 41, thereby playing the role of being able to replace the electromagnetic pressure gauge 44 for pressure detection during a power outage, and being able to perform comparative detection with the electromagnetic pressure gauge 44 to ensure the accuracy of the pressure data. When the pressure gauge 45 is not needed, release the pressure gauge 45, and the pressure spring 46 rebounds to reset the pressure gauge 45.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a monitoring mechanism 5, which includes a fixed frame 51, a motor 52, a gear 53, a ring gear 54, a connecting frame 55, a monitoring probe 56 and an alarm light 57. The left and right parts of the connecting valve 2 and the control valve 42 are connected to the fixed frame 51, the upper side of the fixed frame 51 is connected to the motor 52, the output shaft of the motor 52 is connected to the gear 53, the outer side of the fixed frame 51 is rotatably connected to the ring gear 54, the ring gear 54 is meshed with the adjacent gear 53, the left and right sides of the upper part of the ring gear 54 are connected to the connecting frame 55, the lower side of the connecting frame 55 is connected to the monitoring probe 56, the upper side of the connecting frame 55 is connected to the alarm light 57, and the alarm light 57 is connected to the adjacent monitoring probe 56 through electric wires.

[0037] The monitoring mechanism 5 of the device can be used to automatically monitor whether gas leaks occur. The motor 52 is started to mesh the gear 53 with the ring gear 54, so that the ring gear 54 drives the connecting frame 55 to rotate, and the monitoring probe 56 rotates to monitor whether there is gas leakage at the connection. This can automatically monitor whether gas leaks occur, save manpower, and avoid omissions. When the monitoring probe 56 detects gas leakage, the alarm light 57 is controlled to light up to prompt the user.

[0038] like Figure 1 and Figure 7As shown, it also includes a knocking mechanism 6, which includes a support frame 61, a rotating frame 62, a torsion spring 63 and a top block 64. Four support frames 61 are connected to the fixed frame 51, and the supporting frames 61 are rotatably connected to the rotating frames 62. Two torsion springs 63 are connected between the rotating frames 62 and the connected support frames 61. From left to right, the first, fourth, fifth and eighth connecting frames 55 are connected to the top blocks 64, and the top blocks 64 are squeezed and fitted with the rotating frames 62.

[0039] The knocking mechanism 6 of the device can promote gas diffusion and monitor whether the pipeline connection is loose. When the connecting frame 55 moves, the top block 64 is driven to move, so that the top block 64 squeezes the rotating frame 62, and the torsion spring 63 is deformed, so that the rotating frame 62 rotates away from the main pipeline 1 or the connecting pipe 41. After the top block 64 is separated from the rotating frame 62, the torsion spring 63 is restored, so that the rotating frame 62 is reset to knock the main pipeline 1 or the connecting pipe 41. The sound during knocking can be used to determine whether the pipeline connection is loose, thereby promoting gas diffusion and improving leakage detection efficiency. At the same time, it can monitor whether the pipeline connection is loose and improve the safety of gas use.

[0040] like Figure 1 and Figure 8 As shown, a sealing mechanism 7 is also included, and the sealing mechanism 7 includes a support member 71, an air pump 72, an air guide tube 73 and an inflation airbag 74. The middle part of the fixed frame 51 is connected to the support member 71, and the upper side of the support member 71 is connected to the air pump 72. The monitoring probes 56 are connected to the adjacent air pumps 72 through electric wires, and the air pumps 72 are connected to the air guide tubes 73. The air guide tubes 73 pass through the adjacent fixed frames 51. The inner side of the fixed frames 51 is connected to the inflation airbag 74, and the inflation airbag 74 is connected to the adjacent air guide tube 73.

[0041] The sealing mechanism 7 of the device can be used to seal the pipe connection. When the monitoring probe 56 detects a gas leak at the pipe connection, the air pump 72 is controlled to start and inflate the expansion airbag 74 through the air guide tube 73, so that the expansion airbag 74 expands and blocks the pipe connection, thereby sealing the gas leak and preventing gas leakage.

[0042] like Figure 1 and Fig. 9 As shown, a prompt mechanism 8 is also included, which includes a fixed block 81, a rotating shaft 82 and a rotating plate 83. The fixed block 81 is connected to the upper right side of the connecting tube 41, and the fixed block 81 is located on the left side of the electromagnetic pressure gauge 44. The fixed block 81 is rotatably connected to the rotating shaft 82, and the rotating shaft 82 is rotatably connected to the connecting tube 41. Three rotating plates 83 are connected to the lower part of the rotating shaft 82.

[0043] By using the prompt mechanism 8 of the device, the gas situation in the connecting pipe 41 can be displayed. When the gas is introduced into the connecting pipe 41, the rotating plate 83 is pushed to rotate, causing the rotating shaft 82 to rotate. When the gas stops being introduced, the rotating shaft 82 stops rotating, thereby displaying the gas situation in the connecting pipe 41 and making it easier for users to know.

[0044] like Figure 1 and Fig.10 As shown, an auxiliary mechanism 9 is also included. The auxiliary mechanism 9 includes a fixing seat 91 and a temperature sensor 92. The fixing seat 91 is connected to the front side of the middle of the connecting pipe 41, and the front side of the fixing seat 91 is connected to the temperature sensor 92.

[0045] The auxiliary mechanism 9 of the device can detect the temperature of the connecting pipe 41. The temperature sensor 92 on the fixing seat 91 senses the temperature of the connecting pipe 41, thereby detecting the temperature of the connecting pipe 41 and facilitating timely detection of abnormal conditions of the connecting pipe 41.
