Description

A smart home combustible gas detector with alarm function Technical Field

[0001] This utility model relates to the field of combustible gas detection technology, and in particular to a smart detection and alarm household combustible gas detector. Background Technology

[0002] As people's living standards continue to improve, the use of natural gas and liquefied petroleum gas in households is becoming increasingly common. While bringing convenience to life, this also brings the risk of gas leaks leading to explosions, fires, and poisoning. As an important safety protection device, combustible gas detectors can monitor the concentration of combustible gases in the environment in real time and issue an alarm in a timely manner when the gas concentration reaches the danger threshold. Based on this, intelligent detection and alarm home combustible gas detectors have emerged. These detectors integrate intelligent sensing and wireless communication technologies on the basis of traditional detection and alarm functions, enabling high-precision and automated gas detection. By linking with the functions of smart home devices, they provide users with a more intelligent, convenient, and comprehensive safety protection experience.

[0003] A search revealed Chinese Patent Publication No. CN212432973U, which discloses an all-around intelligent combustible gas laser detection device. This device includes a control processor, a horizontal rotating motor, a vertical rotating motor, a combustible gas laser detector, a housing, a power supply, and an alarm. The control processor is electrically connected to the horizontal rotating motor, the vertical rotating motor, the combustible gas laser detector, the power supply, and the alarm. This invention addresses the problems of existing technologies where, due to the large number of process equipment in oil and gas field stations, dispersed leak sources, complex leak gas composition, single detector component detection, large number of detectors, high construction and maintenance costs, and small detector protection range limited by wind direction, this system can achieve 360° horizontal and 360° vertical multi-directional timed and positional detection of combustible gases. This reduces the number of combustible gas detectors required in the horizontal and vertical planes, lowering investment. However, in actual use, this detection device can only provide an alarm function and cannot shut off the combustible gas based on concentration, resulting in the inability to stop leaks in a timely manner. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a smart detection and alarm household combustible gas detector, which aims to improve the problem that the existing technology cannot shut off combustible gas according to the concentration, thus failing to prevent leakage in time.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a smart detection and alarm household combustible gas detector, comprising a base plate, a top cover slidably connected to the top of the base plate, hollow columns fixedly connected to the four corners inside the base plate, circular grooves slidably connected to the tops of the hollow columns, and cylindrical columns fixedly connected to the four corners at the bottom of the top cover, with the bottoms of the cylindrical columns penetrating the circular grooves and slidably connected to the interiors of the corresponding hollow columns. An inlet valve and an outlet valve are fixedly connected to the front and rear sides of the top left end of the circular groove, respectively. Both the valve and the outlet valve have external connecting pipes on their left sides. A detector is fixedly connected to the top of the circular groove. Both the inlet valve and the outlet valve have connecting pipes on their right sides. The right ends of both connecting pipes are connected to the left side of the detector. A U-shaped frame is fixedly connected to the left side of the circular groove. A telescopic rod is fixedly connected to the top of the inner side of the U-shaped frame. A horizontal plate is fixedly connected to the bottom of the telescopic rod. Isolation plates are fixedly connected to the front and rear sides of the bottom of the horizontal plate. The bottoms of the two isolation plates pass through the tops of the inlet valve and the outlet valve, respectively. An installation mechanism is provided at the bottom of the base plate.

[0006] The above technical solution allows for the following: When using this intelligent detection and alarm household combustible gas detector, the top cover slides along the top of the base plate, allowing the cylinder at the bottom of the top cover to be inserted into the circular groove at the top of the hollow column inside the base plate. This completes the assembly of the detector. External combustible gas enters through the external pipe connected to the left side of the inlet valve, and is transmitted to the detector via the connecting pipe. The detector detects and analyzes the gas to determine its concentration. After detection, the gas is discharged through the outlet valve via the external pipe connected to its left side. When the detected combustible gas concentration reaches a set threshold, the detector triggers an alarm mechanism. The telescopic rod at the top of the inner side of the U-shaped frame moves the horizontal plate up and down, and the isolation plate at the bottom of the horizontal plate moves accordingly, passing through the top of the inlet and outlet valves respectively, thereby controlling the entry and exit of gas and facilitating equipment maintenance and calibration.

[0007] As a further description of the above technical solution:

[0008] The mounting mechanism includes two fixing plates. The tops of the two fixing plates are fixedly connected to the front and rear sides of the bottom of the base plate, respectively. Each of the two fixing plates has a sliding groove on an adjacent side. Sliding plates are slidably connected to the left and right sides of the interior of each of the two sliding grooves. Multiple adjustment holes are provided at the bottom of each of the two fixing plates. Adjusting bolts are rotatably connected to the front and rear sides of the bottom of each of the two sliding plates. Mounting plates are fixedly connected to the rear ends of each of the two sliding plates. Mounting holes are provided at the top of each of the two mounting plates.

[0009] The above technical solution allows for the following: when the installation position of the detector needs to be adjusted left or right, the position of the sliding plate is fixed by adjusting the bolts and adjusting holes. The adjusting bolts are rotatably connected to the front and rear sides of the bottom of the sliding plate. By screwing the adjusting bolts into the appropriate adjusting holes, the sliding plate can be stably fixed on the fixed plate, thereby determining the position of the detector in the left and right direction. The rear end of the sliding plate is fixedly connected to the mounting plate, and the mounting holes on the top of the mounting plate are used to install the detector at the target position.

[0010] As a further description of the above technical solution:

[0011] The top of the top cover has a ventilation hole one, and the bottom plate has ventilation holes two on both the left and right sides of the front end.

[0012] The above technical solution involves opening one vent on the front side of the top of the top cover and opening two vents on the left and right sides of the front end of the bottom plate. The two work together to form a good gas flow channel.

[0013] As a further description of the above technical solution:

[0014] The top of the top cover has a groove, and a rotating cover is rotatably connected to the left side of the inside of the groove.

[0015] The above technical solution prevents dust and debris from entering the detector when the cover is closed, thus avoiding damage to internal components.

[0016] As a further description of the above technical solution:

[0017] A warning light is fixedly connected to the top right side of the circular groove, and a reserved hole is opened inside the right side of the groove, through which the top of the warning light passes.

[0018] With the above technical solution, when the detector detects that the concentration of combustible gas exceeds the standard, the warning light will illuminate, visually sending an alarm signal to the user from the top of the cover.

[0019] As a further description of the above technical solution:

[0020] The U-shaped frame has sliding grooves on both the front and back sides, and the horizontal plate has sliders fixedly connected to both the front and back sides.

[0021] The above technical solution provides guidance and stable support for the up-and-down movement of the horizontal plate, so that when the telescopic rod moves the horizontal plate, the horizontal plate can move the isolation plate up and down more smoothly.

[0022] As a further description of the above technical solution:

[0023] The outer walls of the plurality of adjusting bolts are slidably connected with washers, and the tops of the plurality of washers are respectively attached to the bottoms of the corresponding fixing plates.

[0024] Through the above technical solution, the shim can increase the contact area between the adjusting bolt and the fixing plate, making the fixation more secure and preventing the adjusting bolt from damaging the surface of the fixing plate.

[0025] As a further description of the above technical solution:

[0026] A sealing ring is fixedly connected to the bottom of the top cover, and a sealing groove is provided on the top of the bottom plate.

[0027] The above technical solution forms a tight, sealed structure after the top cover and bottom plate are assembled.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by sliding the top cover along the top of the base plate, the bottom cylinder of the top cover is inserted into the top groove of the hollow column, thus completing the stable assembly of the detector. External combustible gas enters the detector through the inlet valve external pipe and connecting pipe. After detection, the gas is discharged from the outlet valve external pipe. When the gas concentration exceeds the standard, the detector triggers an alarm, and the telescopic rod moves the horizontal plate and isolation plate, realizing the rapid detection of gas leaks and automatic shutdown of the gas source, effectively avoiding explosions or poisoning accidents caused by continuous gas leaks.

[0030] 2. In this utility model, the sliding plate slides left and right in the sliding groove of the fixed plate, and then the adjusting bolts rotatably connected to the front and rear sides of the bottom of the sliding plate are screwed into the appropriate adjusting holes at the bottom of the fixed plate, thereby stably fixing the sliding plate on the fixed plate. The mounting plate at the rear end of the sliding plate is thus positioned, realizing the adjustment of the detector installation position in the left and right directions, which can adapt to different installation environments and ensure that the detector can be installed in the optimal detection position.

[0038] 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.

[0039] Referring to Figures 1, 3, and 4, this utility model provides an embodiment of a smart household combustible gas detector. A base plate 1 serves as the basic component. A top cover 3 is slidably connected to the top of the base plate 1, making it easy to open or close. Hollow columns 4 are fixedly connected to the four corners inside the base plate 1, providing support and guidance, and offering a stable foundation for the sliding connection of circular grooves 5 and cylindrical columns 6. Circular grooves 5 are slidably connected to the tops of the multiple hollow columns 4, precisely guiding the sliding of the cylindrical columns 6 and ensuring accurate alignment when the top cover 3 is connected to the base plate 1. Cylindrical columns 6 are fixedly connected to the four corners at the bottom of the top cover 3, and the bottoms of the multiple cylindrical columns 6 penetrate through the circular grooves 5. It slides internally with the corresponding hollow column 4, ensuring a stable connection between the top cover 3 and the bottom plate 1, while maintaining relative sliding stability after connection. An inlet valve 7 and an outlet valve 8 are fixedly connected to the front and rear sides of the top left end of the circular groove 5, respectively. The inlet valve 7 controls the entry of combustible gas, and the outlet valve 8 controls the discharge of detected gas. The two work together to achieve orderly gas flow. Both the inlet valve 7 and the outlet valve 8 have external connecting pipes 9 connected to their left sides. These external connecting pipes 9 connect to external pipelines, allowing the detector to communicate with the external gas environment and facilitating gas entry and exit. A detector 10 is fixedly connected to the top of the circular groove 5. The detector 10 is the core detection component, capable of detecting and analyzing the incoming gas to determine the presence of [gases / gases]. Regarding the combustible gas and concentration, both the inlet valve 7 and the outlet valve 8 are connected to a connecting pipe 11 on their right sides. The right ends of both connecting pipes 11 are connected to the left side of the detector 10. The connecting pipes 11 are used to transport the gas to the detector 10, ensuring that the gas can smoothly reach the detection area. A U-shaped frame 12 is fixedly connected to the left side of the circular groove 5. The U-shaped frame 12 provides installation support for components such as the telescopic rod 13, ensuring their stable operation. A telescopic rod 13 is fixedly connected to the top inner side of the U-shaped frame 12. The telescopic rod 13 can drive the horizontal plate 14 to move through its extension and retraction, thereby controlling the inlet valve 7 and the outlet valve 8. A horizontal plate 14 is fixedly connected to the bottom end of the telescopic rod 13. The horizontal plate 14 is used to connect the isolation plate 15. The power of the telescopic rod 13 is transmitted to the isolation plate 15. Isolation plates 15 are fixedly connected to the bottom front and rear sides of the horizontal plate 14. The bottom of the two isolation plates 15 passes through the top of the air inlet valve 7 and the air outlet valve 8 respectively. The air inlet valve 7 and the air outlet valve 8 are opened or closed by moving the isolation plates 15 up and down to control the gas flow. The bottom of the base plate 1 is provided with an installation mechanism 2. The installation mechanism 2 can adjust the position of the detector according to different installation environments. The bottom of the top cover 3 is fixedly connected with a sealing ring 25. The top of the base plate 1 is provided with a sealing groove 26. The sealing ring 25 and the sealing groove 26 cooperate to form a sealing structure to prevent external dust and moisture from entering the detector and ensure detection accuracy and detector service life.

[0040] Specifically, the detector is fixed in a suitable position using the mounting mechanism 2. The mounting mechanism 2 can be flexibly adjusted to adapt to different installation environments. Then, the top cover 3 is slid along the top of the base plate 1, so that the cylinders 6 at the four corners of the bottom of the top cover 3 are respectively inserted into the circular grooves 5 at the top of the hollow cylinders 4 at the four corners inside the base plate 1, thus connecting the top cover 3 to the base plate 1. At the same time, the sealing ring 25 at the bottom of the top cover 3 is embedded in the sealing groove 26 at the top of the base plate 1 to ensure the internal sealing of the detector and prevent external dust and moisture from entering. When the detector starts working, external combustible gas enters through the external pipe 9 connected to the left side of the inlet valve 7 and is transported to the detector through the connecting pipe 11. The detector 10 performs real-time detection on the incoming gas to determine whether there is combustible gas and whether its concentration exceeds the standard. If the concentration of combustible gas exceeds the safety threshold, the detector will trigger an alarm mechanism. During the detection process, the inlet valve 7 and the outlet valve 8 can be controlled according to the actual situation. When it is necessary to stop the gas intake or adjust the gas flow, the telescopic rod 13 on the top inner side of the U-shaped frame 12 drives the horizontal plate 14 to move downward. The isolation plates 15 on the front and rear sides of the bottom of the horizontal plate 14 pass through the top of the inlet valve 7 and the outlet valve 8 respectively, so as to close or adjust the valves. After the detection is completed, the gas is discharged from the detector through the outlet valve 8 and the external pipe 9 connected to its left side.

[0041] Referring to Figures 2 and 5, the mounting mechanism 2 includes two fixing plates 201, providing a mounting carrier for subsequent structures. The tops of the two fixing plates 201 are respectively fixedly connected to the front and rear sides of the bottom of the base plate 1, achieving a stable connection between the mounting mechanism 2 and the detector body base plate 1. Each of the two fixing plates 201 has a sliding groove 202 on an adjacent side, providing guidance and space for the sliding plate 203 to slide. Sliding plates 203 are slidably connected to the left and right sides of the interior of each sliding groove 202, allowing the sliding plates 203 to slide left and right within the grooves, thus adjusting the detector's mounting position laterally. Each of the two fixing plates 201 has multiple adjustment holes 204 at its bottom, which cooperate with adjustment bolts 205 to fix the sliding plates 203 in the desired position. Adjusting bolts 205 are rotatably connected to the front and rear sides of the bottom of the device. The adjusting bolts 205 lock the sliding plate 203 by screwing into the adjusting hole 204 to ensure the stability of the adjusted position. The rear ends of the two sliding plates 203 are fixedly connected to the mounting plate 206. The mounting plate 206 provides a connection medium between the detector and the mounting surface. The top of the two mounting plates 206 is provided with mounting holes 207. The mounting holes 207 facilitate the use of screws and other connectors to fix the mounting plate 206 to the wall or other mounting surface. The outer walls of the multiple adjusting bolts 205 are slidably connected with washers 24. The washers 24 can increase the contact area between the adjusting bolts 205 and the fixing plate 201. The tops of the multiple washers 24 respectively fit against the bottom of the corresponding fixing plate 201, which plays a role in anti-slip and anti-wear, and at the same time enhances the stability during fixing.

[0042] Specifically, when the detector needs to be installed, its left and right positions can be adjusted according to the actual installation location requirements. The specific operation involves allowing the sliding plate 203 to slide left and right within the sliding groove 202 on the adjacent side of the fixed plate 201. During adjustment, to ensure the sliding plate 203 remains stable in the required position, the adjusting bolt 205 is rotatably connected to the front and rear sides of the bottom of the sliding plate 203. After the sliding plate 203 has slid to the appropriate position, the adjusting bolt 205 is screwed into the corresponding adjusting hole 204 at the bottom of the fixed plate 201. At this time, the shim 24, which is slidably connected to the outer wall of the adjusting bolt 205, will fit against the bottom of the fixed plate 201. The shim 24 not only increases the contact area between the adjusting bolt 205 and the fixed plate 201, making the fixation more secure, but also prevents the adjusting bolt 205 from damaging the surface of the fixed plate 201, thus providing anti-slip and protection. Once the position of the sliding plate 203 is fixed, the detector can be installed using the mounting plate 206.

[0043] Referring to Figures 3, 4, and 5, a vent 16 is provided on the front top of the top of the top cover 3. The vent 16 is used to guide external gas into the detector so that the detector 10 can perform detection. Vent 2 17 is provided on both the left and right sides of the front end of the bottom plate 1. The vent 2 17 cooperates with the vent 16 to form a smoother gas flow path, ensuring that the gas fully enters the detector. A groove 18 is provided on the top of the top cover 3. The groove 18 provides a protective space for internal components and facilitates the installation of components such as the rotating cover 19. The rotating cover 19 is rotatably connected to the left side of the inside of the groove 18. The rotating cover 19 can open or close the groove 18, providing an operating entrance when it is necessary to inspect or adjust internal components. When not in use, it serves to prevent dust and foreign objects from entering. The top of the circular groove 5... A warning light 20 is fixedly connected to the right side of the part. The warning light 20 illuminates when the detector 10 detects that the concentration of combustible gas exceeds the standard, giving the user a clear visual alarm signal. A reserved hole 21 is provided on the right side of the inside of the groove 18. The reserved hole 21 provides a channel for the warning light 20 to pass through the top cover 3, so that the warning light 20 can display the warning from the top of the top cover 3. Slide grooves 22 are provided on the front and rear sides of the inside of the U-shaped frame 12. The slide grooves 22 provide guidance for the movement of the horizontal plate 14, ensuring the stability and accuracy of the horizontal plate 14 when it moves up and down. Slider 23 is fixedly connected to the front and rear sides of the horizontal plate 14. The slider 23 cooperates with the slide groove 22, so that the horizontal plate 14 can slide smoothly along the slide groove 22, thereby controlling the operation of the isolation plate 15 on the inlet valve 7 and the outlet valve 8.

[0044] Specifically, vent 16 is located on the front top of the top cover 3, and vent 2 17 is located on the left and right sides of the front end of the base plate 1. The two work together to form a good gas flow channel. When the cover 19 is closed, it can prevent dust and debris from entering the detector and avoid damage to the internal components. When the detector 10 detects that the concentration of combustible gas exceeds the standard, the warning light 20 lights up, which directly sends an alarm signal to the user from the top of the top cover 3. It provides guidance and stable support for the up and down movement of the horizontal plate 14, so that when the telescopic rod 13 moves the horizontal plate 14, the horizontal plate 14 can move the isolation plate 15 up and down more smoothly.

[0045] Working principle: When using this intelligent detection and alarm household combustible gas detector, the top cover 3 is slid along the top of the base plate 1, so that the cylinder 6 at the bottom of the top cover 3 is inserted into the circular groove 5 at the top of the hollow column 4 inside the base plate 1, thus assembling the detector. Combustible gas from the outside enters through the external pipe 9 connected to the left side of the inlet valve 7, and is transmitted to the detector 10 through the connecting pipe 11. The detector 10 detects and analyzes the gas to determine the concentration of combustible gas. After the detection is completed, the gas is discharged through the outlet valve 8 and the external pipe 9 connected to its left side. When the detected combustible gas concentration reaches the set threshold, the detector 10 triggers the alarm mechanism. The telescopic rod 13 at the top of the inner side of the U-shaped frame 12 drives the horizontal plate 14 to move up and down. The isolation plate 15 at the bottom of the horizontal plate 14 moves accordingly, passing through the top of the inlet valve 7 and the outlet valve 8 respectively, so as to realize the opening or closing operation of the inlet valve 7 and the outlet valve 8, thereby controlling the gas in and out, and facilitating equipment maintenance and calibration operations.

[0046] Furthermore, when it is necessary to adjust the installation position of the detector left or right, the position of the sliding plate 203 is fixed by adjusting the bolt 205 and adjusting the hole 204. The adjusting bolt 205 is rotatably connected to the front and rear sides of the bottom of the sliding plate 203. By screwing the adjusting bolt 205 into the appropriate adjusting hole 204, the sliding plate 203 can be stably fixed on the fixed plate 201, thereby determining the position of the detector in the left and right direction. The rear end of the sliding plate 203 is fixedly connected to the mounting plate 206. The mounting hole 207 opened at the top of the mounting plate 206 is used to install the detector at the target position.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
