Embodiment
Gas detecting instrument described in the utility model, comprises housing, gas piping, sensor, battery, PCB, and housing is combined by upper shell as shown in Figure 1, 2 and lower house, and is screwed.Its top is provided with draft tube opening and escape pipe opening, draft tube opening part is provided with the draft tube joint laid respectively on upper shell and lower house inwall and fixes screens 1a and 1b, upper shell inside surface is provided with PCB fixed bolt 2, lower house inside surface top is provided with air pump pickup groove 3, middle part is provided with sensor seating groove 4, bottom is provided with battery pickup groove 5, its escape pipe opening part is provided with wireway and fixes muscle 6, air pump pickup groove 3 left and right sides is arranged at intervals with multiple wireway guiding tendon position 7, in order to fixing wireway.
The parts of different composition can be set in above-mentioned housing, form the gas detecting instrument of following two kinds of forms:
A kind of is pump suction gas detector as shown in Figure 3, screens 1a fixed by its draft tube joint, draft tube joint 8 is provided with in 1b, as shown in Figure 4, the flexible pipe 9a that draft tube joint 8 connects is communicated to sensor air chamber 10 behind wireway guiding tendon position 7, sensor air chamber 10 is connected in sensor seating groove 4, sensor air chamber 10 outlet hose 9b is communicated to air pump 11 after wireway guiding tendon 7, air pump 11 is arranged in air pump pickup groove 3, air pump 11 outlet hose 9c is communicated to escape pipe joint 12a behind wireway guiding tendon position 7, escape pipe joint 12a(is as Fig. 7, shown in 8) wireway that is connected to described escape pipe opening part fixes in muscle 6, the sensor of sensor air chamber 10 is connected with the first PCB 13 be fixed on PCB fixed bolt 2.As shown in Figure 5,6, above-mentioned draft tube joint 8 is provided with and fixes the circular groove structure 19a and side grain structure 20a that screens 1a, 1b match with draft tube joint.
Another kind is the spy gun-type gas detecting instrument such as shown in Fig. 9,10, the sonde-type sensor 14 being positioned at hull outside is connected with the second PCB 16 by connecting line 15, connecting line 15 is positioned at the swan neck 17 be connected with sensor 14, the swan neck gland 18 that swan neck 17 end connects is arranged on draft tube joint and fixes in screens 1a, 1b, second PCB 16 is connected on PCB fixed bolt 2, and the wireway of escape pipe opening part fixes in muscle 6 the escape pipe joint 12b being provided with and having blind header structure as shown in fig. 13 that.As shown in Figure 11,12, swan neck gland 18 is provided with and fixes the circular groove structure 19b and side grain structure 20b that screens 1a, 1b match with draft tube joint.
