Description

Technical Field

[0001] This utility model relates to the field of gas meter box technology, specifically a visualized gas meter box. Background Technology

[0002] In the supply and use of natural gas, gas flow meters, as key energy metering devices, play an indispensable role in achieving accurate and safe gas distribution. However, due to the complex working environment of gas flow meters, they are susceptible to various factors such as temperature, humidity, corrosion, and vibration, leading to shortened service life, decreased measurement accuracy, and even safety accidents. Therefore, researching and implementing effective protection measures, such as extending the service life of gas flow meters and improving their measurement accuracy and safety through the installation of gas meter boxes, is of significant practical importance. For example, a smart gas meter box based on the Internet of Things (IoT) with announcement number CN211552974U includes a gas meter box body and a third gas meter. A first inlet pipe is inserted into the gas meter box body, and a first ball valve is installed on the first inlet pipe. The lower end of the first inlet pipe is connected to a first gas meter, which has a first gas outlet, and a first gas flow meter is installed on the first gas outlet. This IoT-based smart gas meter box, by installing a first solenoid valve and a first gas flow meter on the first gas meter, a second solenoid valve and a second gas flow meter on the second gas meter, a third solenoid valve and a third gas flow meter on the third gas meter, and a fourth solenoid valve and a fourth gas flow meter on the fourth gas meter, allows for remote control of the opening and closing of the first, second, third, and fourth gas meters. It also facilitates viewing gas usage data and improves user convenience. However, this IoT-based smart gas meter box still has the following drawbacks in practical use:

[0003] Traditional gas meter boxes often have gaps between the gas pipes and the box body after installation. These gaps are usually sealed by wrapping adhesive. However, when the pipes need to be repaired or disassembled, the sealing structure will be damaged, and subsequent reconnection will be inconvenient. Therefore, the sealing structure is not designed reasonably.

[0004] Meanwhile, most gas meter boxes are equipped with gas leak sensors, which detect leaking gas and issue alarms. However, after a gas leak occurs, it can fill the entire gas meter box and even spread to the outside of the gas meter box, causing pollution and increasing the danger. In response to the above problems, there is an urgent need to innovate the design of the existing gas meter box. Summary of the Invention

[0005] The purpose of this invention is to provide a visualized gas meter box to solve the problems mentioned in the background art, such as the unreasonable sealing structure of traditional gas meter boxes, the fact that gas leaks can fill the entire gas meter box and even spread to the outside of the gas meter box, causing pollution and increasing danger.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visualized gas meter box, including a box body, a door hinged to the front of the box body, and a flow meter installed on the inner bottom surface of the box body. The top of the flow meter is connected to two gas pipes through flanges to form a gas transmission path, and the end of the gas pipe away from the flow meter passes through the side of the box body.

[0007] It also includes: a sealing component, which is disposed between the gas pipeline and the through hole on the side wall of the box. The sealing component dynamically seals the gap of the gas pipeline passing through the box through a flexible sealing ring, and the through hole is opened on the side of the box. The two sides of the box are equipped with outward-sloping rainproof louvers, which allow ventilation while preventing rainwater, dust and foreign objects from entering the equipment. Combined with the guide channel and drainage structure, it ensures that rainwater will not seep into the interior.

[0008] The detection mechanism is located at the connection between the gas pipeline and the flow meter. The detection mechanism is connected to the gas leak sensor, and the gas leak sensor is connected to the alarm. Both the gas leak sensor and the alarm are installed on the inner wall of the enclosure.

[0009] Preferably, the sealing assembly includes a second airbag adhered to the inside of the through hole, and the second airbag is interconnected with the first airbag through an air supply channel. The first airbag is located on the outside of the housing, and both the first and second airbags are annular structures.

[0010] Preferably, the gas supply channel is located on the inner wall of the box, and an adjusting cylinder is rotatably installed on the inner top surface of the box. Both ends of the adjusting cylinder are threaded with lead screws, and a connecting plate is fixed to the end of the lead screw away from the adjusting cylinder.

[0011] Preferably, the connecting plate has an annular structure, and the width of the connecting plate annulus is greater than the width of the first airbag annulus. A limit rod is fixed at the end of the connecting plate away from the lead screw, and both the limit rod and the lead screw are slidably connected to the housing.

[0012] Preferably, the detection mechanism includes a sleeve fitted at the bottom of the gas pipeline, with the sleeves symmetrically distributed on the outside of the gas pipeline, and a movable rod fixed to the side of the sleeve, wherein the movable rod and the support plate are slidably connected.

[0013] Preferably, the support plate is fixed at the edge of the flow meter, the end of the movable rod away from the flow meter is in close contact with the side of the guide block, and a spring is provided on the movable rod near the door. The guide block is fixed to the side of the door, and the surface of the guide block has an arc-shaped structure.

[0014] Preferably, a rack is fixed to the side of the housing, and the rack has an "L" shaped structure. The rack and the gear are meshed together, and a movable shaft is fixedly inserted inside the gear. The movable shaft is rotatably mounted on the flow meter.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this visualized gas meter box can quickly seal the gaps between the gas pipeline and the box body, and will not damage the sealing structure after the gas pipeline is repaired or disassembled, facilitating resealing. At the same time, when detecting gas leaks, the leaked gas will not spread indefinitely, thereby reducing the danger. The specific details are as follows:

[0016] 1. Rotating the adjusting cylinder, through the threaded transmission with the lead screw, drives the two lead screws and two connecting plates to move closer to each other, and compresses the first airbag so that the gas inside is transmitted to the second airbag through the gas transmission channel. After the second airbag expands, it can seal the gap at the through hole position, ensuring the sealing of the gas pipeline after installation. When the gas pipeline needs to be repaired and disassembled in the future, the sealing component can be reused.

[0017] 2. When the box door is closed, the guide block can push the movable rod to slide. When one of the sleeves moves, the meshing of the gear and rack will make the two sleeves move closer to each other and fit tightly on the connection between the gas pipeline and the flow meter to ensure the sealing of the connection.

[0018] Furthermore, when a gas leak occurs at the connection, the leaked gas will only enter the casing and will not spread to other locations. When the box door is opened, the guide block releases the push of the movable rod. Through the spring's elasticity and the meshing transmission of gears and racks, the two casings are moved away from each other, and the gas pipeline is no longer sealed, making it convenient for maintenance personnel to operate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-8 The present invention provides the following technical solution:

[0030] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a visualized gas meter box, comprising a box body 1, a door 2 hinged to the front of the box body 1, and a flow meter 3 installed on the inner bottom surface of the box body 1. The top of the flow meter 3 is connected to two gas pipes 4 via flanges to form a gas transmission path, and the end of the gas pipe 4 away from the flow meter 3 extends through the side of the box body 1; it also includes: a sealing assembly, disposed between the gas pipe 4 and the through hole 5 on the side wall of the box body 1, the sealing assembly using a flexible sealing ring to seal the gas pipe 4. Dynamic sealing is performed through the gaps in the enclosure, and the through hole 5 is opened on the side of the enclosure 1. The two sides of the enclosure 1 are equipped with outward-sloping rainproof louvers, which allow ventilation while preventing rainwater, dust and foreign objects from entering the equipment. Combined with the guide channel and drainage structure, it ensures that rainwater will not seep into the interior. The detection mechanism is set at the connection between the gas pipeline 4 and the flow meter 3. The detection mechanism is connected to the gas leak sensor 20, and the gas leak sensor 20 is connected to the alarm 21. Both the gas leak sensor 20 and the alarm 21 are installed on the inner wall of the enclosure 1.

[0031] In existing gas meter boxes, gaps often appear between the gas pipe 4 and the box body after installation. These gaps are mostly sealed using a wrapping adhesive. However, when pipe maintenance or disassembly is required, the sealing structure is damaged, making subsequent reconnection inconvenient. Therefore, the sealing structure is not designed reasonably. Figures 1-4As shown, the sealing assembly includes a second airbag 12 adhered to the inner side of the through hole 5, and the second airbag 12 is interconnected with the first airbag 10 through the gas supply channel 11. The first airbag 10 is located on the outer side of the housing 1, and both the first airbag 10 and the second airbag 12 are annular structures. The gas supply channel 11 is located on the inner wall of the housing 1, and an adjusting cylinder 6 is rotatably mounted on the inner top surface of the housing 1. Both ends of the adjusting cylinder 6 are threaded with lead screws 7, and a connecting plate 8 is fixed to the end of the lead screw 7 away from the adjusting cylinder 6. The connecting plate 8 is annular, and the width of the annulus of the connecting plate 8 is greater than the width of the annulus of the first airbag 10. A limiting rod 9 is fixed to the end of the connecting plate 8 away from the lead screw 7, and both the limiting rod 9 and the lead screw 7 are slidably connected to the housing 1. When the gas pipeline 4 is connected to the housing 1... The gap at the through hole 5 is relatively large. Therefore, rotating the adjusting cylinder 6, through the threaded transmission with the lead screw 7, causes the two lead screws 7 to move closer together because the thread grooves on the two lead screws 7 are in opposite directions. This allows the lead screw 7 and the limiting rod 9 to slide on the housing 1, and also causes the two connecting plates 8 to move closer together to compress the first airbag 10. The gas in the first airbag 10 is transmitted to the second airbag 12 through the gas transmission channel 11. After the second airbag 12 expands, it can seal the gap at the through hole 5, ensuring the sealing of the gas pipeline 4 after installation. Even if the gas pipeline 4 needs to be repaired and disassembled later, rotating the adjusting cylinder 6 in the opposite direction can release the compression of the first airbag 10 by the connecting plate 8. In this way, the second airbag 12 will no longer seal the gap, and the sealing component can be reused later.

[0032] Example 2: Most existing gas meter boxes are equipped with gas leak sensors 20, which detect leaking gas and issue an alarm. However, after a gas leak, it can fill the entire gas meter box and even spread to the outside, causing pollution and increasing the risk. Therefore, this example uses the following technical solution, such as... Figures 5-8As shown, the detection mechanism includes a housing 14 fitted at the bottom of the gas pipeline 4, with the housing 14 symmetrically distributed on the outside of the gas pipeline 4. A movable rod 15 is fixed to the side of the housing 14, and the movable rod 15 and the support plate 16 are slidably connected. The support plate 16 is fixed to the edge of the flow meter 3. The end of the movable rod 15 away from the flow meter 3 is in contact with the side of the guide block 13. A spring is provided on the movable rod 15 near the door 2, and the guide block 13 is fixed to the side of the door 2, with an arc-shaped surface. A rack 17 is also fixed to the side of the housing 14, and the rack 17 has an "L"-shaped structure. The rack 17 and the gear 18 are meshed, and a movable shaft 22 is fixedly inserted through the inside of the gear 18. The movable shaft 22 is rotatably mounted on the flow meter 3. When the door 2 is closed, it can drive the guide block 13 to contact the movable rod 15, and push the movable rod 15 against the support plate 16. The slides upwards. When one of the sleeves 14 moves, it can drive one of the racks 17 to move. Through the meshing of the gear 18, it drives the other rack 17 to move in the opposite direction. In this way, the two sleeves 14 can move closer to each other and fit tightly at the connection between the gas pipeline 4 and the flow meter 3, ensuring the sealing of the connection. When a gas leak occurs at the connection, the leaked gas will only enter the sleeve 14 and will not spread to other locations. The leaked gas can be transmitted to the gas leak sensor 20 through the gas delivery hose 19, and then transmitted to the alarm 21 to issue an alarm, which facilitates timely maintenance of the gas meter box. When the box door 2 is opened, the guide block 13 releases the push of the movable rod 15. Through the elasticity of the spring, one of the sleeves 14 moves away from the gas pipeline 4. Through the meshing of the gear 18 and the rack 17, the two sleeves 14 move away from each other, no longer sealing the gas pipeline 4, which facilitates the operation of maintenance personnel.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
