Description

Technical Field

[0001] The utility model belongs to the technical field of flue gas monitors, and relates to a portable flue gas monitor. Background Art

[0002] A flue gas monitor is a device that continuously analyzes and measures the content of flue gas such as CO2, CO, NOx, SO2, etc. using an electrochemical sensor.

[0003] A flue gas on-line monitoring device disclosed in Chinese Patent CN215678277U includes a lower box body, an upper box body and a flue gas detector body. The lower box body is detachably connected to the upper box body. Both the lower box body and the upper box body are cylindrical structures. The flue gas detector body is arranged in the lower box body. The flue gas detector body is arranged on an L-shaped sliding plate. An electric telescopic rod is arranged on one side of the L-shaped sliding plate. A protective cover is arranged on one side of the lower box body. An air outlet is arranged at the top of the upper box body, and a fan is arranged below the air outlet.

[0004] When the flue gas on-line monitoring device is in use, first, the electric telescopic rod pushes the L-shaped sliding plate to move. The L-shaped sliding plate touches the touch button, so that the controller controls the micro bidirectional motor to drive the rotating part to rotate, thereby opening the protective cover and exposing the flue gas detector body to the air for detection. After the detection is completed, the protective cover needs to be rotated again to seal the flue gas detector in the box body, and then the fan is turned on to clean the inside of the box body and discharge the residual gas. Therefore, during operation, it is necessary to operate the electric push rod, the bidirectional motor and the fan respectively, and the operation is relatively cumbersome. Moreover, using multiple driving parts such as the electric push rod and the bidirectional motor will increase the production cost.

[0005] To solve the above problems, the utility model proposes a portable flue gas monitor. Content of the Utility Model

[0006] To solve the problems in the background art, the utility model proposes a portable flue gas monitor.

[0007] To achieve the above object, the technical solution adopted by the utility model is as follows: it includes a box body, an upper cover is slidably arranged inside the box body, and a telescopic component is arranged inside the box body. The telescopic component drives the upper cover to slide vertically up and down inside the box body;

[0008] A rotating shaft is rotatably connected to the bottom of the upper cover, a fan blade is fixedly connected to the bottom of the rotating shaft, and a transmission component is arranged at the bottom of the upper cover. The transmission component drives the rotating shaft to rotate;

[0009] A ventilation opening is formed in the middle of the upper cover, and a flue gas detector is installed on the bottom surface of the inner cavity of the box body.

[0010] Further, the telescopic assembly includes an electric push rod, the electric push rod is fixedly connected to the bottom surface of the inner cavity of the box body, and the top end of the telescopic rod at the output end of the electric push rod is fixedly connected to the bottom surface of the upper cover.

The connecting shaft is rotatably connected to the fixed block through a bearing, and both the left and right ends of the connecting shaft extend out of the fixed block;

[0012] A first bevel gear is fixedly connected to the right end portion of the connecting shaft, a second bevel gear is fixedly sleeved on the rotating shaft, and the first bevel gear and the second bevel gear are meshed;

[0013] A driving member is arranged inside the box body, and the driving member drives the connecting shaft to rotate.

[0014] Further, the driving member includes a rack, the rack is fixedly connected to the inner wall of the box body, and the top end of the rack slides through the upper cover;

[0015] A spur gear is fixedly sleeved on the left end portion of the connecting shaft, and the spur gear is meshed with the rack.

[0016] Further, a guide rod is fixedly connected to the inner wall of the box body. The guide rod and the rack are symmetrically arranged inside the box body, and the top end of the guide rod slides through the upper cover.

[0017] Further, a U-shaped handle is arranged above the upper cover, and the two end portions of the handle are respectively fixedly connected to the rack and the guide rod.

[0018] Further, an L-shaped support frame is fixedly connected to the bottom of the upper cover. The rotating shaft is rotatably connected to the support frame through a bearing, and the fan blade is located below the support frame.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The portable flue gas monitor is provided with an upper cover, and a fan blade is rotatably arranged at the bottom of the upper cover. During use, the telescopic assembly is used to drive the upper cover to move upward. When the upper cover moves upward, it will drive the fan blade to rotate clockwise, so as to suck external air into the box body while opening the upper cover, which is convenient for the flue gas detector to perform detection. After the detection is completed, when the upper cover is moved downward, the fan blade is driven to rotate counterclockwise, so that the upper cover seals the box body while the fan blade discharges the residual gas. Therefore, during the detection, it is only necessary to drive the upper cover to move up and down, and the operation is simple.

[0021] 2. The portable flue gas monitor is provided with a rack, a spur gear, a first bevel gear and a second bevel gear, so that when the upper cover moves up and down, the flue gas detector can complete the detection of the flue gas without driving the fan blade to rotate again, reducing the production cost.

The top end of the telescopic rod at the output end of the electric push rod 16 is fixedly connected to the bottom surface of the upper cover 7.

[0032] A rotating shaft 17 is rotatably connected to the bottom of the upper cover 7, and a fan blade 14 is fixedly connected to the bottom of the rotating shaft 17. An L-shaped support frame 15 is fixedly connected to the bottom of the upper cover 7. The rotating shaft 17 is rotatably connected to the support frame 15 through a bearing, and the fan blade 14 is located below the support frame 15. A transmission assembly is provided at the bottom of the upper cover 7, and the transmission assembly drives the rotating shaft 17 to rotate.

[0033] The transmission assembly includes a connecting shaft 9. A fixed block 11 is fixedly connected to the bottom of the upper cover 7.
