Description

Technical Field

[0001] The present invention relates to the technical field of independent combustible gas detectors, and specifically to an independent combustible gas detector with Internet of Things network transmission function. Background Art

[0002] Combustible gas detectors are used for long-term continuous monitoring of the combustible gas content in the air. They are installed in places where combustible gas is prone to leakage. They can convert the combustible gas concentration into an electrical signal output. Independent combustible gas detectors do not need to be connected to a host and a dedicated power supply to complete independent work. They also have functions such as sound and light alarms, high and low limit alarm contact outputs, etc.

[0003] During the use of the independent combustible gas detector, it does not have the function of removing dust and protecting its detection end. In this way, dust will accumulate on the detection end during the use of the independent combustible gas detector, which may hinder the combustible gas from reaching the sensor smoothly, thereby affecting the sensitivity and accuracy of the detector. When there is too much dust, it may even cause the detector to be unable to detect combustible gas leaks in time, resulting in missed reports, and the detection end cannot be protected, and there is a risk of external force collision. If the detector is installed in a location that is prone to external force collision, such as near a door, passage or children's activity area, adding a protective structure can prevent the detection end from being damaged due to collision, affecting the normal operation of the detector.

[0033] The working principle of the above embodiment is:

[0034] The gas detector body 1 is fixed to the main body of the building or other equipment by the fixing hole block 4 before use. During the fixing process, expansion bolts are required for auxiliary fixing. When the independent gas detector body 1 is fixed by the fixing hole block 4, the main board in the independent gas detector body 1 can complete the detection of combustible gas. The main board arranged in the independent gas detector body 1 has the functions of information storage and information transmission. The current independent gas detector body 1 can upload the gas detection results and the working status of the whole machine to the upper computer management platform in a wireless manner. The user can directly view the measured gas concentration and the overall working status of the detector remotely, thereby ensuring that the device has the function of Internet of Things network transmission. The implementation of this function on the existing main board is a mature technology, and thus this application will not go into too much detail. The main board of this application is C79451-A3478-S504. This application highlights the innovative structure, highlights the dust removal and protection of the detection end 5 of the independent gas detector body 1, ensures the use effect of the overall device, and the structure of this application is simple, the effect is obvious, and can improve the use performance of the overall device.

[0035] The protection of the detection terminal 5 by the protective groove drum 6 can avoid the problem of the detection terminal 5 being hit, and the first air vent 601 and the second air vent 602 on the protective groove drum 6 can ensure normal gas detection of the detection terminal 5, and the inclined setting of the first air vent 601 can avoid the problem of dust adhesion. The control of the inclination angle can make the impurities have a larger downward force under the action of the gravity component, which is more conducive to the impurities sliding down by themselves, and the frustum structure setting of the second air vent 602 makes its surface relatively inclined, so that dust slides down more easily under the action of gravity. Compared with the flat surface or other shapes, the dust attached to the frustum hole of the frustum hole has a greater tendency to slide down along the cone surface under the influence of its own gravity, so it is not easy to accumulate, thereby reducing the adhesion of impurities on the surface of the protective groove drum 6;

[0036] And when the device is in use, it can generate propulsion gas by pressing the movement of the disc 1004, so that the spiral air supply pipe 1101 can be used to accelerate the delivery to the protective groove drum 6, thereby ensuring that the technical protective groove drum 6 has impurities attached and can be well cleaned. The pressing disc 1004 will drive the push ring 1002 to slide in the outlet tube 1001 through the push rod 1003, thereby producing a piston pushing effect, so that the gas in the outlet tube 1001 will be transported to the spiral air supply pipe 1101, because the first check valve 1008 here only allows gas to be inhaled from the outside of the device into the air delivery cavity 8, and the second check valve 1102 only allows gas to be blown from the air delivery cavity 8 to the outside of the device, so that the gas in the outlet tube 1001 will enter the spiral air supply pipe 1101 through the second check valve 1102. The air supply pipe 1101, and the spiral acceleration of the spiral air supply pipe 1101 is introduced into the protective groove drum 6, and the left and right spiral air supply pipes 1101 are arranged front and back, and the air outlet position is the same direction, so that the accelerated gas discharged through the two spiral air supply pipes 1101 will continue to rotate and flow in the protective groove drum 6, and finally be discharged through the first air vent 601 and the second air vent 602, thereby increasing the impurity removal effect on the surface of the protective groove drum 6, and thus can greatly avoid the problem of the device being affected by dust. When the pressing disc 1004 is released, under the elastic force of the spring 1006, the push rod 1003 will run in the opposite direction of the above-mentioned running trajectory, and then can inhale through the first check valve 1008 under the elastic force of the spring 1006, thereby ensuring the effect of supplying air to the spiral air supply pipe 1101 next time.

[0037] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
