[0021] The principles and features of the present utility model will be described below in conjunction with the drawings. The examples given are only for explaining the present utility model and do not limit the scope of use of the present utility model.

[0022] As Figures 1-3 shown, the present utility model provides a sewage treatment plant abnormal gas collection and detection device, which includes a chassis 1, a collection air hood 3 and a plurality of gas collecting bottles 7. A traveling wheel 16 is installed at the bottom of the chassis 1. A horizontal partition is fixedly provided in the middle of the interior of the chassis 1. A pipe reel 4 is provided above the partition. A storage and release opening is formed above the left side of the chassis 1. A telescopic support mechanism is provided in the chassis 1 near the first storage and release opening. A first sealing door 11 is installed on the chassis 1 outside the storage and release opening. The first sealing door 11 can effectively seal the storage and release opening during non-working hours to prevent external sundries from entering the interior of the chassis 1.

[0023] The telescopic support mechanism includes a motor 14, a first connecting rod 21, a second connecting rod 22, and a third connecting rod 23. The lower ends of the first connecting rod 21 and the second connecting rod 22 are rotatably connected to the inner wall of the chassis 1 through corresponding rotating shafts and are on the same horizontal line. The other end of the first connecting rod 21 is rotatably connected to the middle of the third connecting rod 23, and the other end of the second connecting rod 22 is rotatably connected to the upper end of the third connecting rod 23. The collection air hood 3 is installed at the lower end of the third connecting rod 23 where it is movably arranged; the motor 14 is installed on the chassis 1, and the output shaft of the motor 14 is coaxially fixed to the rotating shaft at the lower end of the first connecting rod 21. When the motor 14 drives the first connecting rod 21 to rotate counterclockwise, the second connecting rod 22 will also rotate counterclockwise, causing the lower end of the third connecting rod 23 to swing upward with the collection air hood 3 and extend out of the retractable opening, so that the collection air hood 3 is placed above the sewage tank for gas detection and collection, making it more convenient to use. After the operation is completed, the collection air hood 3 can be retracted back into the interior of the chassis 1 by driving the connecting rod to rotate in the reverse direction by the motor 14.

[0024] The collection air hood 3 is connected to the coil inlet of the pipe reel 4 through a collection hose 31; a gas detection sensor is installed on the collection air hood 3. When the telescopic support mechanism drives the collection air hood 3 and the collection hose 31 to extend outwards or retract inwards, the pipe reel 4 can automatically release or wind up the pipe, so as to effectively store the collection hose 31 and avoid the pipe entanglement from affecting the movement of the collection air hood 3.

[0025] The outlet of the coil is connected to the inlet end of the air pump 5. The outlet end of the air pump 5 is respectively connected to the filter box 9 and the first air valve 61 through a tee 51, and a second air valve 62 is installed between the tee 51 and the filter box 9. The first air valve 61 is respectively connected to the inlet of the gas collecting bottle 7 below the transverse partition through a corresponding connecting hose; a third air valve 71 and a pressure gauge 72 are also installed at the inlet of the gas collecting bottle 7. The third air valve 71 is used to control the opening and closing of the inlet of a single gas collecting bottle 7, and the pressure gauge 72 is used to detect the gas pressure in the gas collecting bottle 7, so as to judge whether the gas collecting bottle 7 is full of sample gas.

[0026] An exhaust pipe 15 connected to the outlet of the filter box 9 is provided above the chassis 1. After all the gas collecting bottles 7 are filled, the third air valve 71 and the first air valve 61 are closed, and the second air valve 62 is opened. The gas is pumped into the filter box 9 by the air pump 5, and the abnormal gas will be effectively absorbed and purified by the filter element in the filter box 9 and then discharged through the exhaust pipe 15, thus effectively avoiding environmental pollution.

[0027] An inspection opening is provided on the side wall of the chassis 1 close to the filter box 9, and a second sealed door 12 is installed at the inspection opening. Opening the second sealed door 12 can replace the filter element and perform maintenance on the filter box 9 through the inspection opening.

[0028] On the front side of the chassis 1, there is a third sealed door 13. Inside the chassis 1 below the cross partition, there is a mounting rack 8. On the mounting rack 8, there are multiple fixing seats 81. The gas cylinder 7 is detachably installed on the fixing seats 81. At the front and rear of the bottom of the chassis 1, slide rails 17 are installed, and the bottom of the mounting rack 8 is installed on the moving sliders of the slide rails 17. Opening the third sealed door 13 can pull out the mounting rack 8 outward, making it more convenient to install and remove the gas cylinder 7 on the fixing seats 81.

[0029] On both side walls of the mounting rack 8, there are locking parts that cooperate with the inner wall of the chassis 1. The locking parts include a plug rod 82, a limit block 823, and a spring 824. Horizontally penetrating openings 80 are provided on the side walls of the mounting rack 8, and the plug rod 82 is horizontally movably inserted through the openings 80. One end of the plug rod 82 is a clamping part 821, and at the end of the clamping part 821, there is an inclined surface. The other end is provided with a handle 82. The clamping part 821 of the plug rod 82 is clamped in the clamping holes 10 opened on the inner wall of the chassis 1. The limit block 823 is fixedly arranged on the plug rod 82 inside the opening 80. The diameter of the limit block 823 is larger than the two openings of the opening 80. The spring 824 is sleeved on the plug rod 82, and both ends of the spring 824 are respectively abutted against the limit block 823 and the inner wall of the opening 80 of the opening 80 far from the clamping part 821.

[0030] Using the cooperation between the clamping part 821 of the plug rod 82 and the clamping holes 10 on the inner wall of the chassis 1 can effectively lock and fix the mounting rack 8. When the gas cylinder 7 needs to be taken and placed, the plug rod 82 is pulled through the handle 82, compressing the spring 824, so that the clamping part 821 of the plug rod 82 disengages from the clamping hole 10, and the mounting rack 8 can be easily pulled outwards. When the mounting rack 8 is pushed back to its original position, due to the inclined surface at the end of the clamping part 821, by abutting against the side wall of the chassis 1 through the inclined surface, the plug rod 82 can be retracted into the opening 80, and the clamping part 821 abuts against the inner wall of the chassis 1 until it is re-clamped into the clamping hole 10 to realize the locking of the mounting rack 8.

[0031] When using the present utility model, move the device to the side of the sewage tank, open the first sealed door 11, drive the collection gas hood 3 to extend out of the chassis 1 and be above the sewage tank through the telescopic support mechanism. When the gas detection sensor detects abnormal gas, the first gas valve 61 and the third gas valve 71 are opened, the second gas valve 62 is closed, and the air pump 5 is started to inflate the gas cylinder 7. When the pressure gauge 72 detects that the pressure of the corresponding gas cylinder 7 reaches the standard and is full of gas, the third gas valve 71 of the corresponding gas cylinder 7 is closed. After all the gas cylinders 7 are full of gas, the first gas valve 61 is closed, the second gas valve 62 is opened, and the gas is purified and filtered through the filter box 9 and then discharged.
