Description

Technical Field

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

[0002] With the development of the times, natural gas has become the main fuel in household life. The main component of natural gas is methane. While natural gas brings convenience to people's lives, it is also flammable and explosive, and there is a possibility of leakage during household use. Natural gas leaks often bring danger, so it is necessary to install natural gas monitoring devices to monitor whether natural gas is leaking. Its core component is a gas sensor, which is installed in places where gas leaks may occur. When the concentration of gas in the air exceeds the set value, the detector will be triggered to alarm and issue an audible and visual alarm.

[0003] For example, Chinese utility model patent (CN219300284U) discloses a liquefied natural gas leak monitoring device, which describes: "When the motor starts running, the threaded rod starts to rotate forward or backward. When the threaded rod is rotating, it can drive the slider that passes through it to move back and forth in the groove. When the slider moves, it can also drive the box to move, so that subsequent monitoring operations can be carried out back and forth, thereby increasing the monitoring range."

[0004] However, the length of the frame in the above-mentioned device determines the travel distance of the gas sensor. Although the monitoring range is expanded, it is difficult to assemble the longer frame, and the longer frame will occupy a lot of space during installation. Therefore, this application proposes a natural gas leak monitoring device. Utility Model Content

[0005] Based on this, it is necessary to provide a natural gas leak monitoring device to address the aforementioned technical problems. Through the overall structural design, it can not only move the natural gas detector but also drive the detector to rotate in a circular motion around the axis, thereby expanding the monitoring range. At the same time, the assembly parts facilitate the installation of fixed-size support brackets and effectively reduce the space occupied during installation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A natural gas leak monitoring device, which is used for natural gas monitoring;

[0008] The device includes a support base, with four mounting parts arranged in an array on the outer side of the upper end of the support base. A sealing plate is fixed inside the support base, and a rotating shaft is rotatably connected to the center of the sealing plate. The upper end of the rotating shaft is rotatably connected to the support base, and a mounting seat is fixed to the lower end of the rotating shaft. A drive assembly is arranged inside the support base and outside the rotating shaft. A hollow screw is rotatably connected inside the mounting seat, and a screw is threadedly connected to the inner side of the hollow screw. A pusher seat is fixed to one end of the screw, and the pusher seat fits into the mounting seat. A natural gas detector is arranged at the bottom of the pusher seat, and L-shaped guide rods are fixed to both sides of the pusher seat. Both L-shaped guide rods fit into the mounting seat.

[0009] In a preferred embodiment of the natural gas leak monitoring device provided by this utility model, the drive assembly includes a first motor. The first motor is fixed inside the bearing support and outside the rotating shaft. A second bevel gear is fixed at the output end of the first motor. A first bevel gear is fixed outside the rotating shaft and above the sealing plate. The first bevel gear and the second bevel gear are meshed together.

[0010] In a preferred embodiment of the natural gas leak monitoring device provided by this utility model, a first flat gear is fixed on the outer side of the hollow screw barrel at the end away from the pusher seat.

[0011] In a preferred embodiment of the natural gas leak monitoring device provided by this utility model, a second motor is fixed at the upper end of the mounting base and outside the rotating shaft, and a second spur gear is fixed at the output end of the second motor, and the second spur gear meshes with the first spur gear.

[0012] In a preferred embodiment of the natural gas leak monitoring device provided by this utility model, a guide fan is installed at the upper end of the guide seat, and a multi-port suction frame is fixed inside the end of the guide seat away from the mounting base. An air extraction pipe is fixedly connected to the air extraction port of the guide fan, and the end of the air extraction pipe away from the guide fan is fixed to the multi-port suction frame. The multi-port suction frame and the air extraction pipe are connected.

[0013] In a preferred embodiment of the natural gas leak monitoring device provided by this utility model, the exhaust port of the duct fan is fixedly connected to an exhaust pipe, and the end of the exhaust pipe away from the duct fan extends to the outside of the natural gas detector.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The natural gas leak monitoring device provided by this utility model, through its overall structural design, not only enables the natural gas detector to move, but also drives the natural gas detector to rotate in a circle around the axis of rotation, thereby expanding the monitoring range. At the same time, the assembly parts facilitate the installation of fixed-size support brackets and effectively reduce the space occupied during installation.

[0016] Furthermore, since natural gas tends to rise when it leaks, a blower is used to draw in air from the multi-port suction frame, creating a negative pressure inside. This allows the multi-port suction frame to easily draw in air at different heights, which is then discharged through the exhaust pipe to the outside of the natural gas detector for detection. This facilitates the immediate detection of natural gas leaks and further enhances the monitoring range for natural gas leaks. Attached Figure Description

Detailed Implementation

[0024] As described in the background art, the length of the frame in the above-mentioned device determines the movement range of the gas sensor. Although this expands the monitoring range, it is difficult to assemble a longer frame, and the longer frame will occupy a lot of space during installation.

[0025] To solve this technical problem, this utility model provides a natural gas leak monitoring device, which is applied to natural gas monitoring;

[0026] The system includes a support 1, with four mounting components arranged in an array on the outer side of the upper end of the support 1. A sealing plate 2 is fixed inside the support 1, and a rotating shaft 3 is rotatably connected to the center of the sealing plate 2. The upper end of the rotating shaft 3 is rotatably connected to the support 1, and a mounting base 7 is fixed to the lower end of the rotating shaft 3. A drive assembly is arranged inside the support 1 and outside the rotating shaft 3. A hollow screw cylinder 8 is rotatably connected inside the mounting base 7, and a screw rod 14 is threadedly connected to the inner side of the hollow screw cylinder 8. A pusher seat 12 is fixed to one end of the screw rod 14 and fits against the mounting base 7. A natural gas detector 15 is arranged at the bottom of the pusher seat 12, and L-shaped guide rods 13 are fixed to both sides of the pusher seat 12. Both L-shaped guide rods 13 fit against the mounting base 7.

[0027] The natural gas leak monitoring device provided by this utility model, through its overall structural design, not only enables the natural gas detector 15 to move, but also, with the help of the drive component, enables the natural gas detector 15 to perform circular motion around the rotating shaft 3, thereby expanding the monitoring range. At the same time, the assembly parts facilitate the installation of the fixed-size support 1, and effectively reduce the space occupied during installation.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] 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.

[0030] Example 1:

[0031] Please refer to Figure 1-4 A natural gas leak monitoring device includes a support 1, and four mounting accessories are arranged in an array on the outer side of the upper end of the support 1. Since the shape and size of the support 1 are fixed, it is easy to install the support 1 using the mounting accessories, and the space occupied during installation is effectively reduced.

[0032] A sealing plate 2 is fixed inside the bearing support 1. A rotating shaft 3 is rotatably connected to the center of the sealing plate 2. The upper end of the rotating shaft 3 is rotatably connected to the bearing support 1. A mounting base 7 is fixed to the lower end of the rotating shaft 3. In order to facilitate the rotation of the rotating shaft 3, a driving component is provided inside the bearing support 1 and outside the rotating shaft 3.

[0033] Specifically, the drive assembly includes a first motor 5, a first motor 5 is fixed inside the bearing support 1 and outside the rotating shaft 3, a second bevel gear 6 is fixed at the output end of the first motor 5, a first bevel gear 4 is fixed outside the rotating shaft 3 and at the upper end of the sealing plate 2, and the first bevel gear 4 and the second bevel gear 6 are meshed and connected.

[0034] A hollow screw cylinder 8 is rotatably connected inside the mounting base 7. A screw 14 is threadedly connected to the inner side of the hollow screw cylinder 8. A pusher seat 12 is fixed to one end of the screw 14. The pusher seat 12 fits against the mounting base 7. A natural gas detector 15 is set at the bottom of the pusher seat 12. The natural gas detector 15 facilitates the detection of natural gas. L-shaped guide rods 13 are fixed on both sides of the pusher seat 12. Both L-shaped guide rods 13 fit against the mounting base 7. When the hollow screw cylinder 8 rotates, the two L-shaped guide rods 13 limit and guide the pusher seat 12, making it easy to drive the pusher seat 12 to move horizontally.

[0035] In order to facilitate the rotation of the hollow screw cylinder 8, a first spur gear 9 is fixed on the outer side of the hollow screw cylinder 8 away from the pusher seat 12. A second motor 10 is fixed on the upper end of the mounting seat 7 and on the outer side of the rotating shaft 3. A second spur gear 11 is fixed on the output end of the second motor 10. The second spur gear 11 meshes with the first spur gear 9.

[0036] Example 2:

[0037] The natural gas leak monitoring device provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, since natural gas will gradually rise when it leaks, in order to facilitate the detection of natural gas leaks as soon as possible and further improve the monitoring range for natural gas leaks, a guide fan 16 is installed at the upper end of the guide seat 12. A multi-port suction frame 17 is fixed inside the end of the guide seat 12 away from the mounting base 7. The suction port of the guide fan 16 is fixedly connected to the suction pipe 18. The end of the suction pipe 18 away from the guide fan 16 is fixed to the multi-port suction frame 17. The multi-port suction frame 17 and the suction pipe 18 are connected. The exhaust port of the guide fan 16 is fixedly connected to the exhaust pipe 19. The end of the exhaust pipe 19 away from the guide fan 16 extends to the outside of the natural gas detector 15.

[0038] The guide fan 16 draws air from the multi-port suction frame 17 to create a negative pressure inside, thus facilitating the intake of air at different heights through the multi-port suction frame 17. The air is then discharged through the exhaust pipe 19 to the outside of the natural gas detector 15 for detection. This allows for the immediate detection of newly leaked natural gas, thereby increasing the monitoring range. All of the above electrical components are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and existing publicly available power connection technologies will not be described in detail here.

[0039] The usage process of the natural gas leak monitoring device provided by this utility model is as follows: First, the fixed-size support 1 is installed and fixed by using the mounting accessories. The first motor 5 is started to drive the second bevel gear 6 to rotate. The meshing of the second bevel gear 6 and the first bevel gear 4 drives the rotating shaft 3 to rotate, which makes it easier to drive the natural gas detector 15 to move in a circle around the rotating shaft 3, thereby increasing the monitoring range of the natural gas detector 15.

[0040] Furthermore, the second motor 10 is activated to drive the second spur gear 11 to rotate. The meshing of the second spur gear 11 with the first spur gear 9 drives the hollow screw cylinder 8 to rotate. This, in conjunction with the L-shaped guide rod 13, guides the pusher seat 12, making it easier to move the pusher seat 12 away from the mounting base 7. This further expands the monitoring range of the natural gas detector 15. At the same time, the structural design of the L-shaped guide rod 13 and the mounting base 7 prevents the pusher seat 12 from separating from the mounting base 7.

[0041] Furthermore, during the monitoring process, the guide fan 16, in conjunction with the multi-port suction frame 17, facilitates the collection of air at different heights and directs it to the outside of the natural gas detector 15, thereby making it easier to detect newly leaked natural gas at the first moment.
