Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen combustion sensors, in particular to a hydrogen combustion detection sensor. Background Art

[0002] A hydrogen combustion detection sensor is a sensor used to detect the gas concentration and flame status during the hydrogen combustion process. This sensor is usually used to monitor the hydrogen combustion conditions in hydrogen combustion equipment, hydrogen generators, hydrogen fuel cells and other systems to ensure that the combustion process is safe and reliable. The sensor determines the presence, size and stability of the flame by detecting the flame generated during the hydrogen combustion process. It usually uses technologies such as photoelectric sensors or infrared sensors to detect the light or infrared radiation generated by the flame to achieve flame detection. It can also monitor the gas concentration during the hydrogen combustion process to ensure that the hydrogen concentration is within a safe range. It usually uses technologies such as chemical sensors or gas sensors to convert the hydrogen concentration into electrical signals for monitoring.

[0003] At present, hydrogen detection sensors are usually installed in areas or near equipment where hydrogen concentration needs to be monitored. Hydrogen detection sensors are usually designed to have hydrogen channels or gas inlets. Hydrogen can enter the sensor through these channels or inlets and react chemically with the materials inside the sensor to achieve hydrogen concentration detection. Since the sensor is usually exposed to the environment, if it is exposed to a dusty environment for a long time, dust is easy to adhere to the air inlet of the sensor, which may cause the air inlet to be blocked and affect the effect of gas entry. Therefore, a hydrogen combustion detection sensor is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a hydrogen combustion detection sensor, which has the advantages of preventing dust from clogging the air inlet holes, etc., and solves the problem that dust is easily attached to the air inlet holes of the sensor when it is exposed to a dusty environment for a long time, which may cause the air inlet holes to be blocked.

[0007] Furthermore, the mounting seat is a cylindrical structure, and an annular plate is fixedly mounted on the top and bottom of the annular mesh cover, and the annular plate on the lower side abuts against the top of the mounting seat.

[0008] Furthermore, arc-shaped plates are fixedly connected to the left and right sides of the top of the mounting frame, an annular groove is provided at the bottom of the rotating seat, and the arc-shaped plate is slidably connected inside the annular groove.

[0009] Furthermore, the annular plate on the upper side abuts against the bottom of the rotating seat, and the cleaning brush contacts the outer wall of the annular mesh cover.

[0010] Furthermore, the outer wall of the air inlet pipe is provided with a plurality of air inlet holes which are equidistantly distributed around the outer wall, and the air inlet holes are strip-shaped grooves.

[0011] Furthermore, the mounting frame is a U-shaped plate, and the mounting frame is in contact with the bottom of the rotating seat.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The hydrogen combustion detection sensor can filter dust in the air by setting a dustproof component and covering the outside of the air inlet pipe with an annular mesh cover.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 A hydrogen combustion detection sensor in this embodiment includes a detection sensor body 1 and an alarm 2. The alarm 2 is installed on the top of the detection sensor body 1. The bottom of the detection sensor body 1 is fixedly connected with an intake pipe 3, and a dustproof component is installed on the outside of the intake pipe 3.

[0020] The dustproof component includes a rotating seat 10, which is fixedly installed on the outside of the air inlet pipe 3. A threaded groove 5 is provided at the bottom of the air inlet pipe 3. A threaded column 6 is connected to the internal thread of the threaded groove 5. A mounting seat 7 is fixedly installed at the bottom of the threaded column 6. A mounting groove 8 is provided at the bottom of the mounting seat 7. A driving motor 9 is fixedly installed inside the mounting groove 8. A rotating rod is fixedly connected to the output shaft of the driving motor 9. A mounting frame 11 is fixedly connected to the bottom of the rotating rod. A cleaning brush 12 is fixed to the left and right inner walls of the mounting frame 11. An annular mesh cover 13 is provided on the outside of the air inlet pipe 3. The mounting seat 7 is a cylindrical structure. Annular plates 14 are fixedly installed on the top and bottom of the annular mesh cover 13. The lower annular plate 14 abuts against the top of the mounting seat 7, and the upper annular plate 14 abuts against the bottom of the rotating seat 10. The cleaning brush 12 contacts the outer wall of the annular mesh cover 13.

[0021] It should be noted that by covering the outside of the air inlet pipe 3 with the annular mesh cover 13, dust in the air can be filtered. When a lot of dust adheres to the outer wall of the annular mesh cover 13, the cleaning brush 12 can be rotated along the outer wall of the annular mesh cover 13 by driving the mounting frame 11 to rotate by the driving motor 9, thereby sweeping down the dust and preventing the dust from affecting the entry of gas.

[0022] See also Figure 1 The left and right sides of the top of the mounting frame 11 are fixedly connected with an arc plate 15. The bottom of the rotating seat 10 is provided with an annular groove. The arc plate 15 is slidably connected inside the annular groove. The mounting frame 11 is a U-shaped plate, and the mounting frame 11 contacts the bottom of the rotating seat 10.

[0023] It can be understood that the annular mesh cover 13 can be supported by the two annular plates 14 respectively contacting the bottom of the rotating seat 10 and the top of the mounting seat 7.

[0024] The threaded column 6 can be moved out of the threaded groove 5 by rotating the mounting seat 7 to make the threaded column 6 rotate, thereby facilitating the disassembly of the mounting frame 11 and the mounting seat 7 and the annular mesh cover 13 .

[0025] It can be understood that the detection sensor body 1 is a hydrogen combustion detection sensor. The hydrogen combustion detection sensor can detect the concentration of hydrogen through a chemical sensor or a gas sensor. These sensors usually use principles such as chemical reactions or gas adsorption to convert the hydrogen concentration into an electrical signal. When the hydrogen concentration exceeds the set threshold, the sensor will sound an alarm or trigger safety measures.

[0026] See also Figure 2 The outer wall of the air inlet pipe 3 is provided with a plurality of air inlet holes 4 which are equally distributed around the air inlet pipe 3. The air inlet pipe 3 is a circular tube, and the air inlet holes 4 are strip grooves.

[0027] It should be noted that, by providing the annular mesh cover 13 on the outside of the air inlet pipe 3 , dust can be prevented from adhering to the outer wall of the air inlet pipe 3 and blocking the air inlet hole 4 , so that the incoming gas passes through the annular mesh cover 13 to filter out the dust therein.

[0028] The working principle of the above embodiment is as follows: when in use, the dust in the air can be filtered by covering the outside of the air inlet pipe 3 with the annular mesh cover 13. When a lot of dust adheres to the outer wall of the annular mesh cover 13, the mounting frame 11 is driven to rotate by the driving motor 9, and the arc plate 15 is rotated in the annular groove, so that the cleaning brush 12 can rotate along the outer wall of the annular mesh cover 13, thereby sweeping down the dust, avoiding the influence of a lot of dust on the entry of gas, and ensuring the accuracy of the detection of the detection sensor body 1.
