Abstract
Description
Technical Field
[0001] This invention relates to a detection device for a mine gas alarm, belonging to the technical field of detection equipment. Background Technology
[0002] Gas detectors are alarm instruments used to detect gas leaks. During the mining process, there are usually some gases such as methane, carbon monoxide, and sulfur-containing gases mixed in the air in the mine. If not careful, these gases can cause poisoning to the miners. Therefore, gas detectors are usually installed in the mine to detect the content of various gases in the air. Once the warning value is reached, an alarm will be triggered. Therefore, it is crucial for the mine alarm to be able to accurately measure the content of various gases in the air. The equipment is tested when the alarm leaves the factory.
[0003] Current detection methods primarily employ sampling, where a gas alarm is manually connected to the circuit, and then the corresponding gas is injected into the detection environment to measure its concentration. This process requires the use of a calibrated standard measuring instrument for comparison to ensure accuracy, making it cumbersome and inefficient.
[0004] Therefore, the present invention proposes a new solution. Summary of the Invention

[0041] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0042] like Figures 1-6 As shown in this embodiment, the detection device for a mine gas alarm includes a housing 1, and further includes:
[0043] Turntable 2 is rotatably mounted on the top of chassis 1. Chassis 1 is equipped with a stepper motor 3 that drives the turntable 2 to rotate.
[0044] The installation mechanism is equipped with multiple sets of equipment that are circumferentially and equally spaced on the top of the turntable 2, which are used to install and fix the mine gas alarm.
[0045] The inflation mechanism is fixedly installed on one side of the turntable 2 and aligned with the center of the turntable 2. It is used to perform inflation when the mine gas alarm rotates to its position.
[0046] The gas alarm controller 23 is installed in the middle of the housing 1 and faces the inflation mechanism.
[0047] When the mine gas alarm rotates between the gas alarm controller 23 and the filling mechanism, the gas alarm controller 23 controls the mine gas alarm to connect electrically with it, and controls the mine gas alarm to connect with the filling mechanism, and performs filling detection.
[0048] To address the problem of low detection efficiency in existing technologies, this application provides a solution. Specifically, the mine gas alarm is placed on an installation mechanism, and a stepper motor 3 drives it to rotate. When the mine gas alarm rotates between the gas alarm controller 23 and the filling mechanism, the gas alarm controller 23 controls the mine gas alarm to connect electrically with it and connects the mine gas alarm to the filling mechanism to perform filling detection, thereby achieving automatic detection, facilitating personnel operation, and effectively improving detection efficiency.
[0049] In an optional embodiment, the mounting mechanism includes:
[0050] Mounting plate 4 is fixedly connected to the top of turntable 2;
[0051] Side plate 5 is fixedly connected to the top edge of mounting plate 4 away from the center of turntable 2;
[0052] The electric telescopic rod 6 is fixedly installed on the top of the mounting plate 4, and its output end faces the side plate 5. The output end of the electric telescopic rod 6 is connected to the push plate 7.
[0053] Terminal 8 is mounted on mounting plate 4 and is used for electrical connection between gas alarm controller 23 and mine gas alarm.
[0054] When in use, place the mine gas alarm between the push plate 7 and the side plate 5, and connect it to the wire of the terminal 8. When it is rotated between the gas alarm controller 23 and the inflation mechanism, start the electric telescopic rod 6 to push the mine gas alarm to connect with the inflation mechanism.
[0055] In an optional embodiment, the mounting mechanism further includes:
[0056] The clamping plate 9 is movably installed between the push plate 7 and the side plate 5, and two symmetrically arranged elastic telescopic rods 10 are fixedly connected between the clamping plate 9 and the side plate 5.
[0057] Two sets of electromagnets 11 are provided and symmetrically installed between the clamping plate 9 and the side plate 5. Each set of electromagnets 11 has two electromagnets, which are respectively installed on the side of the clamping plate 9 and the side plate 5 that are close to each other.
[0058] Mounting holes 12 are provided in the middle of the clamping plate 9 and the side plate 5, for inserting the sensing end of the mine gas alarm.
[0059] In use, the mine gas alarm is placed between the push plate 7 and the clamping plate 9. When it is rotated between the gas alarm controller 23 and the inflation mechanism, the control electromagnet 11 is activated, attracting the clamping plate 9 to move towards the side plate 5, compressing the elastic telescopic rod 10, and at the same time, the electric telescopic rod 6 is activated to push the mine gas alarm so that its sensing end passes through the mounting hole 12 and connects with the inflation mechanism for inflation detection. After the detection is completed, the electric telescopic rod 6 retracts and the electromagnet 11 is turned off at the same time. Under the action of the elastic telescopic rod 10, the clamping plate 9 drives the mine gas alarm to disengage from the inflation mechanism.
[0060] In an optional embodiment, the inflation mechanism includes:
[0061] Air box 13 is fixedly installed on the top of the chassis 1, and a connector 14 is connected to one end of the air box 13 near the turntable 2;
[0062] The standard gas cylinder 15 is connected to the gas box 13 via a connecting pipe and is used to deliver standard gas into the gas box 13. The outlet end of the standard gas cylinder 15 is equipped with a one-way valve.
[0063] The inflation mechanism also includes:
[0064] The vacuum pump 16 is used to draw air from the air tank 13 under negative pressure. The outlet of the vacuum pump 16 is connected to the air storage bottle 17.
[0065] A support frame 18 is fixedly connected to one side of the chassis 1, and the air box 13 is fixedly installed on the support frame 18.
[0066] The connector 14 is used for a sealed connection with the sensing end of the mine gas alarm. When in use, the one-way valve on the standard gas cylinder 15 is opened to fill the gas box 13 with gas. After the test is completed, before disconnecting from the sensing end of the mine gas alarm, the test gas is extracted using the air pump 16 to prevent leakage.
[0067] In an optional embodiment, a through hole is provided in the middle of the chassis 1, and a rotating tube 19 located inside the through hole is fixedly connected to the middle of the bottom surface of the turntable 2. A transmission wheel 20 is connected to the bottom outer wall of the rotating tube 19 and the output end of the stepper motor 3. A transmission belt 21 is connected between the two transmission wheels 20. A support rod 22 is fixedly connected to the middle of the chassis 1, and a gas alarm controller 23 is installed on the top of the support rod 22.
[0068] In an optional embodiment, the push plate 7 is a rubber push plate, and the side of the clamping plate 9 facing away from the side plate 5 is provided with a soft pad. The rubber push plate and soft pad are provided to prevent damage to the mine gas alarm.
[0069] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the detection device for a mine gas alarm provided in this embodiment is as follows:
[0070] Place the mine gas alarm flat on the mounting plate 4, insert its sensing end into the mounting hole 12 on the clamp plate 9, and connect it to the wire of the wiring head 8 at the same time. At this time, the top of the mine gas alarm is facing the push plate 7.
[0071] Stepper motor 3 drives turntable 2 to rotate. When the mine gas alarm rotates between gas alarm controller 23 and gas filling mechanism, gas alarm controller 23 controls the mine gas alarm to be powered on and simultaneously controls electromagnet 11 to start, attracting clamp 9 to move towards side plate 5, compressing elastic telescopic rod 10, and simultaneously starting electric telescopic rod 6 to push the mine gas alarm to move, so that the sensing end of gas alarm controller 23 is connected to connector 14.
[0072] At this time, the one-way valve on the standard gas cylinder 15 is opened to fill the gas tank 13 with gas for testing. After the test is completed, the test gas is extracted using the vacuum pump 16.
[0073] Then, the electric telescopic rod 6 is retracted, and the electromagnet 11 is turned off at the same time. Under the action of the elastic telescopic rod 10, the clamp 9 drives the mine gas alarm to disengage from the gas filling mechanism.
[0074] Finally, when the stepper motor 3 drives the turntable 2 to continue rotating to the next station, the mine gas alarm is removed.
[0075] The above are merely further embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
