Description

Technical Field

[0001] This utility model relates to the field of gas technology, specifically to a gas pipeline leak detection and collection device. Background Technology

[0002] Gas fuels are 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 fuels, mainly including natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas.

[0003] The prior art provides a gas leak detection device for construction (publication number CN221463616U), including a body. A display screen is electrically connected to the side wall of the body. An air extraction cylinder is fixedly connected to the top inner part of the body. A movable rod slides through the air extraction cylinder, and a piston is fixedly connected to the lower end of the movable rod. The upper end of the movable rod passes through the body. This invention, through the movable rod, piston, and pull plate, creates a negative pressure inside the air extraction cylinder by pulling the pull plate upwards. Gas is then collected from the construction site through an air inlet pipe. Simultaneously, a connecting rod connected to the lower end of the pull plate moves a rack and pinion. The meshing gears drive a scraper to rotate via a transmission rod, cleaning the filter at the air inlet pipe port, scraping off accumulated dust, preventing blockage during air collection, and improving the purity of the collected gas, thus enhancing the analytical accuracy of the device.

[0004] Based on the above patent search, the aforementioned patents require manual pulling of a lever to extract and detect surrounding gas during use. Manual operation is slow, which affects the efficiency of gas leak detection. The stability of manual operation is also poor, which may affect the accuracy of gas leak detection. Frequent pulling of the lever by staff over a long period of time will also increase their workload. Therefore, we need to propose a gas pipeline leak collection and detection device.

[0024] 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.

[0025] Please see Figure 1-6This utility model provides a gas pipeline leak detection and collection device, including a housing 1, a gas leak detector 2 for detecting gas leaks installed on the inner top of the housing 1, a fixing plate 3 installed inside the housing 1, and a gas extraction component 4 for extracting gas inside the housing 1.

[0026] The air extraction assembly 4 includes two sets of first rotating rods 41 rotatably mounted on the bottom of the fixed plate 3. Fans 42 are fixedly mounted on the outer side of each set of first rotating rods 41. Multiple sets of air inlet holes 43 are opened at the bottom of the housing 1. A drive assembly 44 for driving the fans 42 to rotate is provided at the bottom of the fixed plate 3.

[0027] The drive assembly 44 includes a motor 441 fixedly mounted on the bottom of the fixed plate 3. The output end of the motor 441 is fixedly connected to a second rotating rod 442 via a coupling. A drive gear 443 is fixedly mounted on the outer side of the second rotating rod 442. Driven gears 444 are fixedly mounted on the outer side of both sets of first rotating rods 41. Both sets of driven gears 444 mesh with the drive gear 443.

[0028] With the drive assembly 44, the motor 441 serves as the power source, directly driving the second rotating rod 442 to rotate via the coupling. The meshing of the driving gear 443 with the two sets of driven gears 444 ensures stable power transmission, enabling the two sets of first rotating rods 41 to rotate synchronously and smoothly, thereby driving the fan 42 to work efficiently. This achieves automated rotation of the fan 42, eliminating the need for manual operation and greatly reducing the complexity and labor intensity of operation.

[0029] A support plate 5 is fixedly installed inside the housing 1, and the bottom ends of the two sets of first rotating rods 41 and second rotating rods 442 are rotatably installed on the top of the support plate 5.

[0030] The support plate 5 provides a stable support point for the first rotating rod 41 and the second rotating rod 442, enabling them to rotate stably without wobbling or shifting. This enhances the structural stability of the entire device and ensures its reliability and safety during operation.

[0031] A through groove 6 is provided on one side of the housing 1, and a filter screen 7 for filtering dust is slidably disposed inside the through groove 6. The filter screen 7 is located directly above the air inlet hole 43.

[0032] By setting up the filter screen 7, the filter screen 7 acts as the first line of defense before the gas enters the housing 1, effectively protecting the detection components inside the housing 1 from dust, impurities and other particulate matter. This helps to extend the service life of the detection components and improve the accuracy and reliability of the detection. The filter screen 7 is slidably set inside the through groove 6. This design makes it very convenient to clean and replace the filter screen 7. When the filter screen 7 accumulates too much dust or impurities, you can simply slide the filter screen 7 out of the through groove 6 for cleaning or replacement, and then slide it back into the through groove 6. This design greatly simplifies the maintenance work and improves the ease of use of the device.

[0033] A limiting component 8 for limiting and fixing the filter screen 7 is provided on one side of the housing 1. The limiting component 8 includes two sets of limiting seats 81 fixedly installed on one side of the housing 1. Limiting rods 82 are slidably installed inside the two sets of limiting seats 81 respectively. Springs 83 are sleeved on the outside of the two sets of limiting rods 82 respectively. Movable plates 84 are fixedly installed on the outside of the two sets of limiting rods 82 respectively. The two sets of movable plates 84 are slidably installed inside the two sets of limiting seats 81 respectively. Limiting holes 85 are opened on both sides of the filter screen 7 for the insertion of the limiting rods 82. The two sets of limiting rods 82 are inserted into the two sets of limiting holes 85 respectively.

[0034] The installation and removal of the filter screen 7 are made very simple by setting the limiting component 8. When removing the filter screen, simply pull out the limiting rod 82 with a little force. At this time, the spring 83 is compressed and stores elastic potential energy. When the limiting rod 82 falls out of the limiting hole 85, the filter screen 7 can be pulled outward to complete the removal. Similarly, when installing the filter screen, simply align the limiting holes 85 on both sides of the filter screen 7 with the limiting rod 82, and then release the limiting rod 82. The elastic potential energy of the spring 83 drives the reset movement, so that the limiting rod 82 is inserted into the limiting hole 85, and the installation of the filter screen 7 can be completed. At the same time, the limiting component 8 also achieves stable fixation of the filter screen 7. This design ensures that the position of the filter screen 7 in the housing 1 will not move arbitrarily, thereby ensuring the stability and reliability of the filtration effect.

[0035] Limiting plates 9 are installed on both sides inside the housing 1. Limiting grooves 10 are provided on both sides of the filter screen 7 for the insertion of the limiting plates 9. The two sets of limiting plates 9 are inserted into the two sets of limiting grooves 10 respectively.

[0036] The limiting plate 9 is inserted into the limiting groove 10 to ensure that the filter screen 7 is in a stable position inside the housing 1, without shaking or shifting, thereby improving the filtration effect.

[0037] Support bases 11 are installed on both sides inside the housing 1, and the bottom of the gas leak detector 2 is fixedly installed on the top of the support base 11.

[0038] The support base 11 provides a stable support structure that helps prevent the detector from falling off or being damaged by external forces, thus ensuring the safety of gas leak detection.

[0039] Working principle: When using this utility model, the motor 441 is started by controlling the button. The motor 441 drives the second rotating rod 442 to rotate. The driving gear 443 on the second rotating rod 442 rotates accordingly and meshes with the driven gears 444 on the two sets of first rotating rods 41, thereby driving the two sets of first rotating rods 41 to rotate simultaneously. When the first rotating rods 41 rotate, the fan 42 fixedly installed on its outer side also rotates, generating suction. Outside air is drawn into the housing 1 through multiple sets of air inlet holes 43 at the bottom of the housing 1. The filter screen 7 filters dust and other impurities in the air to ensure that the gas entering the housing 1 is relatively pure. After the filtered gas enters the housing 1, the fan 42 blows the air towards the gas leak detector 2. The gas leak detector 2 detects the air in real time and analyzes whether it contains components of gas leak. If a gas leak is detected, the gas leak detector 2 will issue an alarm or signal to remind relevant personnel to take timely measures to deal with it.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
