[0002] A combustible gas detector is an instrument that determines whether the concentration of combustible gas is below the lower explosion limit. It is usually made based on the principle of thermal effect and consists of major components such as a gas sampling device, a power supply, a bridge, and a microammeter. The combustible gas detector used at the work site must meet the requirements of the joint explosion stage.

DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] A combustible gas detector for fire protection facility maintenance, such as Figure 1-Figure 9 As shown, it includes a combustible gas detector body 1, an air inlet pipe 2, an exhaust fan 3, an air outlet pipe 4, a limiting ring 401, a dustproof net 5, an elastic card bead 7, a spring 8 and a control panel 9. The top of the combustible gas detector body 1 is penetrated by an air inlet pipe 2, and the combustible gas enters from the air inlet pipe 2. The bottom of the combustible gas detector body 1 is installed with an exhaust fan 3, and the exhaust fan 3 plays a role in accelerating air circulation. The outer side of the exhaust fan 3 is connected to the air outlet pipe 4, and the end of the air outlet pipe 4 away from the exhaust fan 3 is installed with a limiting ring 401. There are several notches in the limiting ring 401, and springs 8 are installed in the limiting ring 401 on both sides of the notches. Elastic beads 7 are connected to the outside of the spring 8. The elastic beads 7 can move into the limiting ring 401. A dustproof net 5 is movably installed on the side of the limiting ring 401. The dustproof net 5 prevents small insects and impurities from entering the combustible gas detector body 1. Several protrusions are arranged on the side of the dustproof net 5. The protrusions are slidably engaged with the elastic beads 7. A control panel 9 is installed on the side of the combustible gas detector body 1.

[0027] When it is necessary to replace the dust screen 5 on the outside of the air outlet pipe 4, rotate the dust screen 5, squeeze the protrusion of the dust screen 5 against the elastic card bead 7, and the elastic card bead 7 moves along the spring 8 into the limiting ring 401, and the protrusion leaves the elastic card bead 7, and the clamping relationship is released, and the dust screen 5 can be taken out to the outside. Similarly, the cleaned dust screen 5 or a new one can be installed, which facilitates replacement. The protective net 15 arranged on the outside of the air inlet pipe 2 is designed according to the same principle.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1 , Figure 2 and Figure 8As shown, it also includes a buzzer 6, an alarm light 10, a limit plate 11, an anti-collision plate 12, a buffer strip 13, an anti-collision shell 14 and a protective net 15. The buzzer 6 is installed on the side of the combustible gas detector body 1, and the alarm light 10 is installed on the top of the combustible gas detector body 1. The alarm light 10 is connected to the control panel 9 by signal. The limit plate 11 is installed on the side of the combustible gas detector body 1, and the limit plate 11 is arranged inside the limit plate 11. A number of buffer strips 13 are installed on the side of the anti-collision plate 12. The anti-collision shell 14 is movably installed with a protective net 15 away from the end of the combustible gas detector body 1. The protective net 15 is located on the outside of the air inlet pipe 2, and the anti-collision shell 14 is arranged on the outside of the air inlet pipe 2.

[0030] The anti-collision plate 12 and the buffer strip 13 installed on the side of the combustible gas detector body 1 play a shock-proof role, and the buzzer 6 serves as a reminder to replace the dustproof net 5 and the protective net 15. When the combustible gas detector body 1 detects that the combustible gas exceeds the standard, the control panel 9 sends a start signal to the alarm light 10, and the alarm light 10 works and sends an alarm signal to remind the staff.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
