Description

Technical Field

[0001] This utility model belongs to the field of gas detection technology, and in particular relates to a multi-point detection flammable gas detection device. Background Technology

[0002] Combustible gas detectors are detectors that respond to the concentration of one or more combustible gases. There are two types of combustible gas detectors: catalytic and infrared optical. Catalytic combustible gas detectors use the change in resistance of a heated refractory platinum wire to determine the concentration of combustible gas. When combustible gas enters the detector, it causes an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated raises the temperature of the platinum wire, and the resistivity of the platinum wire changes. Infrared optical detectors use infrared sensors to detect alkane combustible gases in the environment through the absorption principle of infrared light sources. For leaks of flammable gases, detection equipment is required for detection.

[0003] Existing flammable gas detection equipment can only detect gas leaks at a single location. Due to the different densities of the gases being detected, some gases will sink while others will float, which limits the detection equipment and can lead to inaccurate detection.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0044] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0045] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0046] like Figures 1 to 5 As shown, a multi-point detection flammable gas detection device according to an embodiment of the present invention includes:

[0047] The test box 1 is equipped with a test component 2, an air supply component 3, an air intake component 4, and a flame retardant component 5.

[0048] The intake assembly 4 is connected to the detection assembly 2 via the air supply assembly 3;

[0049] Detection component 2 includes:

[0050] The detector 21 is fixedly installed inside the detection box 1;

[0051] An air pump 22 is fixedly installed in the detection box 1 on the side close to the detector 21. The air inlet of the air pump 22 is connected to the detector 21, and the air outlet is fixedly installed with an exhaust pipe 23.

[0052] Gas supply component 3 includes:

[0053] An air supply box 31 is fixedly installed inside the detection box 1. A motor 32 is fixedly installed on the end face of the air supply box 31. A rotating ball 33 and a blocking block 34 are fixedly installed on the output shaft of the motor 32.

[0054] Three rotating balls 33 are equidistantly distributed on the output shaft of motor 32;

[0055] The gas supply line 35 is fixedly installed at the bottom of the gas supply box 31, and the gas supply line 35 is connected to the detector 21 through a fixed pipe;

[0056] Electromagnet 36 is fixedly installed in the detection box 1 on the side near the gas supply box 31;

[0057] Specifically, as a further embodiment of this utility model, three baffles are equidistantly installed on the circumference of the blocking block 34, and the air supply assembly 3 also includes a blocking mechanism 37 for limiting the blocking block 34. The blocking mechanism 37 includes:

[0058] The rotating shaft 371 is rotatably fitted inside the detection box 1 on the side close to the electromagnet 36. A fixed barrier plate 372 and a movable barrier plate 373 are fixedly installed on the rotating shaft 371.

[0059] The counterweight 374 is fixedly installed on the end face of the movable barrier plate 373 to limit the movement of the movable barrier plate 373.

[0060] Magnet 375 is fixedly installed at the free end of movable barrier plate 373 for magnetic cooperation with electromagnet 36;

[0061] In this embodiment of the invention, during practical application, the air pump 22 is started, allowing flammable gas to enter the detector 21 through the air intake assembly 4 and the air supply assembly 3, thereby detecting the concentration of flammable gas. The motor 32 is started, driving the rotating ball 33 to rotate via the output shaft, so that one of the three rotating balls 33 is connected to the air intake assembly 4. By rotating the rotating ball 33, the connection between different rotating balls 33 and the air intake assembly 4 can be changed, thereby allowing gas at different heights to be drawn into the detector 21. To avoid rotation... If the rotation amplitude of ball 33 is too large, before the rotating ball 33 rotates, the electromagnet 36 is de-energized and disconnected from the magnetic attraction of magnet 375. The blocking block 34 pushes the fixed blocking plate 372 to rotate. The counterweight block 374 uses gravity to make the movable blocking plate 373 drive the fixed blocking plate 372 to reset. After that, the electromagnet 36 is energized and magnetically attracted to magnet 375. The blocking block 34 is blocked by the fixed blocking plate 372 and cannot rotate, thus limiting the rotation amplitude of the rotating ball 33 and ensuring that gas at different heights can be extracted.

[0062] By configuring the gas supply component 3 and the gas intake component 4, flammable gases at different heights can be detected, thereby increasing the accuracy of flammable gas concentration detection and facilitating the detection of sinking or rising flammable gases. This further expands the detection range of the device. At the same time, when the device draws in gas at different heights, the rotating ball 33 can be limited to increase the accuracy of gas intake at different heights, thereby restricting the entry of gas at other heights and improving the detection effect of flammable gases.

[0063] like Figures 1 to 5 As shown, in a further embodiment of this utility model, the air intake assembly 4 includes:

[0064] The low air intake pipe 41 is rotatably fitted onto the air supply box 31;

[0065] The middle air intake pipe 42 is rotatably fitted onto the air supply box 31 on the side near the low air intake pipe 41;

[0066] The high intake pipe 43 is rotatably fitted onto the air supply box 31 on the side near the middle intake pipe 42;

[0067] Specifically, as a further embodiment of this utility model, the air intake assembly 4 further includes a sealing mechanism 44, which includes:

[0068] The seal 441 is rotatably fitted onto the low intake pipe 41;

[0069] A sealing spring 442 is fixedly installed inside the sealer 441. A sealing rubber gasket 443 is fixedly installed on the end face of the sealer 441. The sealing rubber gasket 443 is elastic.

[0070] The filter screen 444 is snapped onto the end face of the sealer 441 and is used to filter impurities.

[0071] There are three sealing mechanisms 44, which are respectively installed on the end faces of the low air intake pipe 41, the middle air intake pipe 42 and the high air intake pipe 43;

[0072] In this embodiment of the invention, in practical application, gases at different heights can be drawn into the detector 21 for detection. Meanwhile, the sealing rubber pad 443 is pressed against the filter plate 444 by the force of the sealing spring 442, preventing dust and impurities from entering when no gas is being drawn in.

[0073] like Figures 1 to 5 As shown, in a further embodiment of this utility model, the flame-retardant component 5 includes:

[0074] The fixed box 51 is fixedly installed inside the detection box 1 near the top of the detector 21;

[0075] The mounting bracket 52 is fixedly installed inside the mounting box 51;

[0076] The support spring 53 is fixedly mounted on the mounting bracket 52;

[0077] The fixing plug 54 is fixedly installed on the end face of the support spring 53, and the fixing plug 54 also slides with the fixing box 51;

[0078] The connecting rope 55 has its end face connected to the fixed plug 54, and its free end is set inside the detector 21;

[0079] In this embodiment of the invention, when combustion is detected in a flammable gas, the connecting rope 55 is ignited and broken, and the fixing plug 54 moves under the force of the supporting spring 53, causing the fixing box 51 to open. The carbon dioxide inside the fixing box 51 is then rapidly released, thereby limiting the combustion of the flame and preventing the fire from spreading.

[0080] like Figures 1 to 5 As shown, as a further embodiment of this utility model, the detection box 1 is also rotatably fitted with a sealing door 11, and the sealing door 11 is provided with a control panel for controlling other components;

[0081] In this embodiment of the invention, in practical application, it is convenient to open the testing box 1 to repair its internal components, while the control panel facilitates the control of the overall equipment operation.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
