Description

Technical Field

[0001] The invention relates to the technical field of natural gas leakage early warning, in particular to a quick-install natural gas leakage warning device. Background Art

[0002] Natural gas is a multi-component mixed gaseous fossil fuel. Its main components are alkanes, of which methane accounts for the vast majority, and it also contains a small amount of ethane, propane and butane. It is generally colorless and odorless, but for safe use, odorants with special odors are usually added so that leaks can be detected in time. Natural gas can be extracted from underground oil and gas reservoirs, and some of it comes from coal-bed methane. It has a high calorific value and burns relatively cleanly. It produces fewer pollutants such as sulfur dioxide, nitrogen oxides and dust. It is a relatively environmentally friendly energy source. It is widely used in heating, cooking and other fields in life. It is also used in many industries such as power generation and chemical industry in industry. It is an important component of the modern energy structure.

[0003] In practical use, natural gas is flammable, so if it leaks, it will be very dangerous. Usually, it is necessary to set up corresponding natural gas detection devices to assist in detecting whether natural gas leaks;

[0004] A Chinese patent with the announcement number "CN209132938U" discloses a city natural gas leakage alarm device, which includes a fuselage, a mounting plate and a GPS positioning module. The mounting plate is seamlessly welded to the bottom end of the fuselage, and the GPS positioning module is fixedly installed on the top of the fuselage through nuts. The left and right ends of the fuselage are provided with storage tanks, and the storage tanks are both opened and set in the fuselage. The induced draft fan is fixedly installed above the two storage tanks through nuts, and the natural gas sensor is fixedly installed below the induced draft fan through nuts. The battery is fixedly installed at the lower left corner below the natural gas sensor through nuts, and the control panel is fixedly installed on the right side of the battery through nuts. The bottom end of the mounting plate is tightly fitted with a magnetic strip layer. The utility model has good detection effect and a large range, and can detect and monitor both ends of the pipeline at the same time. When natural gas leaks, it can automatically alarm and locate the leak in time, which has high promotion value;

[0005] During the use of the above-mentioned device, although it has shown a certain convenience, it cannot be ignored that it still has some defects and shortcomings. First of all, the device uses a magnetic strip layer to assist adhesion during installation. This installation method does provide a certain convenience in disassembly and assembly. However, since it is installed based on the principle of magnetic attraction, the overall installation strength is relatively low. In actual use, the magnetic strip is very easy to separate from the gas pipe, which causes the device to fall off easily during use. Its overall stability during use is quite poor. In addition, during use, it is difficult to disassemble and separate the natural gas sensor from the device. It should be noted that the natural gas sensor is used outdoors for a long time, and its surface is very easy to adhere to dust, which requires cleaning or maintenance. However, the above-mentioned natural gas sensor is located inside the device, which obviously makes it impossible to disassemble and repair it conveniently and quickly. On the whole, the above-mentioned device has obvious defects in its overall use, so it needs to be improved. Summary of the invention

[0034] See also Figure 1-Figure 7The clamping mechanism 6 includes a sealing plate 61 and a limiting groove 62. The sealing plate 61 is fixedly installed on the top of the mounting frame 8.

The limiting spring 64 can make the limiting column 67 insert into the inner side of the limiting groove 62 at an appropriate time to realize the clamping of the mounting frame 8. This design is convenient and fast, and can efficiently complete the installation and disassembly of the mounting frame 8. Moreover, the various components cooperate closely, and the operation process is simple, which can ensure that the natural gas sensor 9 is stably installed in the device, and ensure the reliability and stability of the device operation.

[0035] The working principle of the present invention is as follows: in the present invention, a mounting mechanism 2 is specially provided. When the present device is put into use, the clamping plates 24 can be placed on both sides of the gas pipe 1. Then, by twisting the adjusting knob handle 25, it will assist in driving the screw rod 22 to rotate inside the mounting rail 21. Since the thread rotation directions at both ends of the screw rod 22 are opposite, the slider 23 can be synchronously driven to slide toward or in the opposite direction on the inner side of the mounting rail 21. The sliding of the slider 23 will drive the clamping plates 24 to perform reciprocating displacement motion. When the two clamping plates 24 slide close to each other, the gas pipe 1 can be clamped and fixed by the clamping plates 24. By tightly clamping the gas pipe 1 by the clamping plates, the present device can be clamped and installed. On the outer surface of the gas pipe 1, after the clamping installation is completed, it is only necessary to twist the hand-tightened screw 27 to insert it into the limiting hole 28. Because the limiting hole 28 and the hand-tightened screw 27 can limit each other, the adjusting knob handle 25 can be assisted to fix the screw rod 22, and then the screw rod 22 can be locked and fixed. In this way, the device as a whole can achieve stable clamping installation. If disassembly is required, it is only necessary to loosen the hand-tightened screw 27 accordingly to let it disengage from the limiting hole 28. At this time, the adjusting knob handle 25 can be loosened to drive the screw rod 22 to reverse, and the screw rod 22 drives the slider 23 to drive the splint to separate, and the gas pipe 1 can be removed. This design can greatly improve the convenience of the overall disassembly, assembly and maintenance of the device.

[0036] In the present invention, by setting up the main control mechanism 5, during the use of the device, the air duct 4 can play the role of guiding air and guide the air into the air duct 4. Once the gas pipe 1 leaks, the natural gas sensor 9 inside the air duct 4 can be used to detect whether the gas is leaking. If the gas leaks, the single-chip controller will control the wireless alarm 56 to sound an alarm. In addition, during use, the photovoltaic panel 52 can convert solar energy into electrical energy and supply it to the battery inside the chassis 53. In this way, the battery can provide the natural gas sensor 9 and the wireless alarm 56 with the electrical energy required for operation. Because the battery and the natural gas sensor 9 are connected by wires, self-sufficiency in electrical energy is achieved. In addition, during use, by setting up the card installation mechanism 6, when installing the natural gas sensor 9, the mounting bracket 8 can be And the natural gas sensor 9 at the bottom is inserted into the installation frame 7. At this time, the guide arm 69 is driven to open the slide plate 65 by twisting the elliptical guide plate 68, so that the limit column 67 moves to both sides. When the natural gas sensor 9 enters the air duct 4, the elliptical guide plate 68 is loosened, and the limit spring 64 is reset to drive the limit column 67 to be inserted into the limit groove 62, thereby realizing the card-connected installation of the natural gas sensor 9. If disassembly is required, it is only necessary to twist the elliptical guide plate 68 again, and the elliptical guide plate 68 will open the guide arm 69 again. The outward movement of the guide arm 69 will drive the limit column 67 at the bottom of the vertical plate 66 to separate from the guide groove. At this time, the mounting frame 8 and the natural gas sensor 9 can be pulled out from the mounting frame 7. It can be seen that the device as a whole performs well in the rapid disassembly and assembly of the natural gas sensor 9, which provides great convenience for the use of the device.
