Description

Technical Field

[0001] This utility model relates to the field of exhaust gas detection and sampling technology, specifically to a rapid detection and sampling device for exhaust gas components used in generator set operation and maintenance. Background Technology

[0002] Generator exhaust mainly contains harmful substances such as nitrogen oxides, particulate matter, carbon monoxide, hydrocarbons and sulfides, which pose a threat to the environment and human health. If inhaled directly, it can easily cause certain harm. Therefore, it is necessary to test the exhaust. Before testing, it is necessary to sample the exhaust, so a gas sampling device is used.

[0003] Although exhaust gas is sampled from a single generator set using an air pump, this method only allows sampling from that specific generator set. If sampling from other generator sets is required, the storage tank must be emptied, which is time-consuming and labor-intensive, reducing sampling efficiency. Therefore, there is an urgent need to design a rapid detection and sampling device for generator set exhaust gas composition to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a rapid detection and sampling device for exhaust gas composition in generator set operation and maintenance, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid detection and sampling device for exhaust gas composition of generator set operation and maintenance includes a container, a partition is installed in the upper part of the container, a plurality of sampling canisters corresponding to the partition are installed in the bottom of the container, a transmission pipe is installed between the partition and the container, and a plurality of transmission components are connected between the transmission pipe and the plurality of sampling canisters.

[0007] The transmission assembly includes an air inlet located around the transmission pipe, a frame installed at the air inlet, a first valve rotatably fitted within the frame, a rod installed in the middle of the first valve, a worm gear installed at the upper end of the rod, a worm rotatably fitted on the upper side of the frame and meshing with the worm gear, an air inlet pipe installed between the frame and the sampling container, and a gas detector installed at the bottom of the container.

[0008] Furthermore, each of the multiple frames has a slot at its bottom and a second valve that is elastically and rotatably fitted at its top. The lower end of each of the multiple second valves is equipped with a block that corresponds to the slot.

[0009] Furthermore, sealing gaskets are installed on the inner side of the plurality of air inlets, the periphery of the plurality of first valves, the periphery of the plurality of second valves, and the inner side of the plurality of slots, and a turntable is installed at one end of the plurality of worm gears.

[0010] Furthermore, multiple turntables rotate and cooperate with the periphery of the container, and multiple sampling tanks and the periphery of the container are provided with interconnected air outlets, and each of the multiple air outlets is equipped with an air outlet pipe.

[0011] Furthermore, a third valve is provided at one end of each of the multiple air outlet pipes, a box is installed on the upper side of the receiving tank, a filter plate is installed inside the box, and a conduit corresponding to the filter plate is connected between the box and the transmission pipe.

[0012] Furthermore, one end of the housing is provided with an opening, and a fourth valve is installed in the opening. One end of the fourth valve is provided with an air extraction pipe corresponding to the filter plate, and one end of the air extraction pipe is provided with an air pump.

[0013] Furthermore, two grooves are symmetrically formed on the lower periphery of the container. One groove houses a display connected to the gas detector, and the other groove contains a transparent plate that rotates within it.

[0015] The beneficial effects of the rapid detection and sampling device for exhaust gas composition in generator set operation and maintenance provided by this utility model are as follows:

[0016] 1. The worm gear is designed to mesh with the worm wheel and rotate, thereby driving the rod body to rotate. This causes the rod body to rotate synchronously with the first valve, which can open or close the air inlet, preparing for the next step of introducing the exhaust gas into the sampling tank.

[0017] 2. By setting up multiple sampling tanks, exhaust gas generated by multiple generator sets can be collected and sampled, saving time and effort. Each air inlet has an independent first valve, which ensures that exhaust gas will not leak into other sampling tanks when entering the sampling tank, effectively improving the efficiency of exhaust gas collection and sampling.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown in the embodiment of this utility model, the rapid detection and sampling device for exhaust gas composition of generator set operation and maintenance includes a container 1, a partition 2 installed in the upper part of the container 1, and a plurality of sampling canisters 3 corresponding to the partition 2 installed in the bottom of the container 1. A transmission pipe 4 is installed between the partition 2 and the container 1. A plurality of transmission components are connected between the transmission pipe 4 and the plurality of sampling canisters 3. The transmission components include an air inlet 5 opened on the periphery of the transmission pipe 4, a frame 6 installed at the air inlet 5, a first valve 7 rotatably fitted in the frame 6, a rod 8 installed in the middle of the first valve 7, a worm gear 9 installed at the upper end of the rod 8, a worm 10 rotatably fitted on the upper side of the frame 6 and meshing with the worm gear 9, and an air inlet pipe 11 installed between the frame 6 and the sampling canisters 3. A gas detector 12 is installed at the bottom of the container 1.

[0026] In this embodiment, a container 1 is included. A partition 2 is installed in the upper part of the container 1. A plurality of sampling cans 3 corresponding to the partition 2 are installed in the bottom of the container 1. A transmission pipe 4 is installed between the partition 2 and the container 1. A plurality of transmission components are connected between the transmission pipe 4 and the plurality of sampling cans 3.

[0027] Specifically, two grooves 24 are symmetrically opened on the lower side of the container 1. One groove 24 is equipped with a display 25 connected to the gas detector 12, and the other groove 24 is fitted with a transparent plate 26. The information detected by the gas detector 12 can be displayed through the display 25, which is convenient for staff to observe and record.

[0028] Specifically, the lower side of the container 1 is equipped with multiple casters 27, and the gas detector 12 is connected to multiple sampling containers 3. The multiple casters 27 effectively improve the flexibility of the container 1.

[0029] In this embodiment, the transmission assembly includes an air inlet 5 opened on the periphery of the transmission pipe 4, a frame 6 installed at the air inlet 5, a first valve 7 rotatably fitted inside the frame 6, a rod 8 installed in the middle of the first valve 7, a worm gear 9 installed at the upper end of the rod 8, a worm 10 rotatably fitted on the upper side of the frame 6 and meshing with the worm gear 9, an air inlet pipe 11 installed between the frame 6 and the sampling tank 3, and a gas detector 12 installed at the bottom of the container 1.

[0030] Specifically, each of the multiple frames 6 has a slot 13 at the bottom of one end, and a second valve 14 is elastically and rotatably fitted at the top of one end of each of the multiple frames 6. Each of the multiple second valves 14 has a locking block 15 corresponding to the slot 13 at the lower end. Through the elastically and rotatably fitted second valve 14, the exhaust gas impacts the second valve 14 and drives it to rotate, thereby opening the air inlet 5. At the same time, if the extraction of exhaust gas stops, the second valve 14 automatically returns to its original position according to its own gravity, thereby closing the air inlet 5.

[0031] Specifically, sealing gaskets 16 are installed on the inner side of multiple air inlets 5, the periphery of multiple first valves 7, the periphery of multiple second valves 14, and the inner side of multiple slots 13, and a turntable 17 is installed at one end of multiple worm gears 10. By setting multiple sealing gaskets 16, the occurrence of exhaust gas leakage can be reduced.

[0032] Specifically, multiple turntables 17 rotate and cooperate with the periphery of the container 1, and multiple sampling tanks 3 and the periphery of the container 1 are provided with interconnected air outlets 18, and each of the multiple air outlets 18 is equipped with an air outlet pipe 19. Through the multiple air outlet pipes 19, the waste gas in the multiple sampling tanks 3 can be discharged.

[0033] Specifically, a third valve is provided at one end of each of the multiple exhaust pipes 19, and a box 20 is installed on the upper side of the container 1. A filter plate 21 is installed inside the box 20. A conduit corresponding to the filter plate 21 is connected between the box 20 and the transmission pipe 4. Through the filter plate 21, particles and dust in the exhaust gas can be intercepted and filtered, thereby reducing the impact of particles and dust on subsequent exhaust gas detection.

[0034] Specifically, one end of the housing 20 has an opening 22, and a fourth valve is installed inside the opening 22. One end of the fourth valve is equipped with an exhaust pipe 23 corresponding to the filter plate 21, and one end of the exhaust pipe 23 is equipped with an air pump. The exhaust gas can be extracted by the air pump to prepare for the next step of extracting it into multiple sampling tanks 3 for collection and sampling.

[0035] Working steps: 1. When sampling and testing the exhaust gas generated by the generator set, first rotate one of its turntables 17, which will drive one of its worm gears 10 to rotate, so that the worm gear 10 meshes with one of its worm wheels 9 and rotates, thereby driving one of its rod bodies 8 and one of its first valves 7 to rotate synchronously, which can open one of its air inlets 5. At this time, the other air inlets 5 are in the closed state. Then start the air pump and open the fourth valve. At this time, the exhaust pipe 23 can collect the exhaust gas generated by the generator set into the housing 20 through the opening 22. At the same time, the filter plate 21 intercepts and filters the particles and dust in the exhaust gas. Then the filtered exhaust gas enters the transmission through the duct. Inside the pipeline 4, the filtered exhaust gas impacts and drives the second valve 14 to rotate. At the same time, the locking block 15 is released from its locking relationship with the locking slot 13, allowing the air inlet 5 to be opened. The filtered exhaust gas is then introduced into the sampling tank 3 through the air inlet pipe 11. At this time, the gas detector 12 is activated to detect the exhaust gas in the sampling tank 3 and transmits the detection information to the display 25 for easy observation and recording by the staff. This enables the sampling and detection of exhaust gas. If it is necessary to sample and detect the exhaust gas generated by other generator sets, the above operation can be repeated.

[0036] Second, when the extraction of exhaust gas stops, the second valve 14 can automatically return to its original position under its own gravity. At the same time, the slot 13 blocks the block 15, thereby automatically closing the air inlet 5 and reducing the possibility of leakage of exhaust gas in the sampling tank 3 due to backflow.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
