Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without any inventive effort, are intended to be within the scope of the utility model.

Example 1:

referring to fig. 1 and 2, a device for detecting abnormal gas accumulation in a carriage during running comprises an accumulation barrel 2 arranged at the top of the carriage 1, wherein two accumulation plates 21 are fixed in the accumulation barrel 2, and the accumulation plates 21 can be folded plates or arc plates. The two gathering plates 21 are oppositely arranged on the same horizontal plane to form a gathering channel 22 with wide ends and narrow middle and in an hourglass shape. In this embodiment, the collecting plates 21 are folded plates, and during running of the vehicle, wind entering the collecting channels 22 is collected into the thinner channels formed by the two collecting plates 21, so that the flow rate of wind can be increased.

Referring to fig. 3 and 4, a mounting hole 23 communicating with the interior of the vehicle compartment 1 is formed at the bottom of the collecting channel 22, and the mounting hole 23 is located at the middle of the collecting channel 22. The top of the carriage 1 is provided with a through hole which is correspondingly communicated with the mounting hole 23, the mounting hole 23 is internally provided with a mounting cylinder 24, and the mounting cylinder 24 is detachably arranged on the bottom inner cylinder wall of the gathering cylinder 2 through bolts. One end of the mounting tube 24 passes through the perforation and protrudes into the interior of the vehicle cabin 1. A vertically arranged mounting plate is fixed in the mounting cylinder 24 and is positioned in the middle of the mounting cylinder 24. The mounting plate is detachably provided with a gas detection device 3 through bolts.

The gas detection device 3 is a waterproof fixed detection device with an alarm, further, a waterproof anticorrosion gas detection alarm provided by Chinese patent publication No. CN210109998U can be selected, when the gas detection alarm is selected, a wall fixing seat of the gas detection alarm is fixed on a mounting plate through a screw, and an air inlet pipeline of the gas detection alarm faces the interior of the carriage 1.

Referring to fig. 4 and 5, during the running of the vehicle, the wind accelerated by the collecting cylinder 2 flows over the mounting cylinder 24, and the faster the flow rate of the fluid, the lower the pressure in the fluid is, according to the bernoulli principle. Therefore, during the running process of the vehicle, the interior of the gathering cylinder 2 is in a negative pressure state, at this time, the pressure in the carriage 1 is high, the gas in the carriage 1 is pumped into the gathering cylinder 2 from the mounting cylinder 24, the gas flowing through the mounting cylinder 24 is detected by the gas detection device 3, whether the gas is abnormal gas is judged, and when the abnormal gas is found, the gas detection device 3 with an alarm function can give an alarm to a driver, so that the driver can discharge dangerous factors in advance.

Because the gathering cylinder 2 gathers the wind outside the carriage 1 into a channel with smaller cross section area, the wind speed is larger compared with the wind speed outside the gathering channel 22, so that the pressure difference between the carriage 1 and the gathering cylinder 2 is also larger, the gas in the carriage 1 can flow to the gathering cylinder 2 more quickly, the gas detection device 3 can contact the gas in the carriage 1 in advance, and compared with the common gas detection device 3 arranged inside the carriage 1, the gas detection device 3 can judge the gas in the carriage 1 more quickly and more efficiently. Meanwhile, the accelerated outflow of the gas in the carriage 1 depends on a physical principle, and extra equipment for extracting the gas is not needed, so that extra energy consumption is reduced.

Referring to fig. 1 and 4, a manhole 26 is formed at the top of the collecting cylinder 2, the aperture of the manhole 26 is larger than that of the mounting hole 23, and the manhole 26 and the mounting hole 23 are coaxially and correspondingly arranged. The top surface of the gathering cylinder 2 is provided with a detachable cover plate 27 which closes the access hole 26. The cover plate 27 is mounted on the top of the gathering cylinder 2 by bolts. When people need to repair or replace the gas detection device 3, the cover plate 27 is removed, so that the gas detection device 3 can be easily removed from the mounting cylinder 24, and the maintenance of the gas detection device 3 is facilitated.

Example 2:

this example is a further improvement over example 1.

Referring to fig. 1 and 6, in the present embodiment, one end of the collecting cylinder 2 in the advancing direction of the vehicle compartment 1 is a streamlined arc-shaped end, and the end is provided with a dust-proof frame 41 that is fitted to the arc-shaped end.

The dust-proof net 43 can prevent foreign matter from entering the collecting cylinder 2 in the case where the collecting cylinder 2 is normally ventilated during running of the vehicle.

Referring to fig. 4, the mounting cylinder 24 is provided with a secondary dust plate 44 toward an end cylinder opening of the collecting duct 22, and the secondary dust plate 44 can prevent foreign matter from entering the interior of the vehicle compartment 1 from the mounting cylinder 24.

Example 3:

this example is a further improvement on the basis of example 1 or example 2.

Referring to fig. 4 and 7, in the present embodiment, the end of the mounting tube 24 away from the collecting tube 2, that is, the end extending into the interior of the vehicle cabin 1, is provided with a detachable rainwater diversion unit 5. The rainwater diversion unit 5 comprises a foreign matter prevention baffle cylinder 51, a collection bucket 52 and a diversion pipe 53. The wall of the foreign matter prevention baffle cylinder 51 is provided with a plurality of ventilation openings 511, and the ventilation openings 511 can prevent foreign matters in the carriage 1 from entering the foreign matter prevention baffle cylinder 51 and ensure that air in the carriage 1 normally flows into the mounting cylinder 24. The foreign matter preventing cylinder 51 is sleeved at one end of the mounting cylinder 24 extending into the carriage 1 and is detachably connected with the mounting cylinder 24 through bolts. The collecting hopper 52 is arranged at the bottom of the foreign matter preventing blocking cylinder 51, the big end of the collecting hopper 52 is fixedly connected with the cylinder bottom of the foreign matter preventing blocking cylinder 51, the small end of the collecting hopper 52, namely the discharge end is fixedly connected with one end of the flow guide pipe 53, and one end of the flow guide pipe 53 away from the collecting hopper 52 extends out of the carriage 1.

During the running of the vehicle when it rains, since the air flow speed above the installation cylinder 24 is high, little rainwater will enter the installation cylinder 24, but there is still no guarantee that rainwater will flow from the accumulation cylinder 2 into the installation cylinder 24. When rainwater flows into the installation cylinder 24, the rainwater flowing into the installation cylinder 24 passes through the installation cylinder 24 and the foreign matter prevention baffle cylinder 51 and falls into the collecting hopper 52, and is then drained to the outside of the carriage 1 under the action of the flow guide pipe 53, so that the rainwater is prevented from directly falling into the carriage 1, and damage of the rainwater to goods is avoided.

The plurality of thrust fans 61 may be provided, and the plurality of thrust fans 61 are each located on a side of the mounting cylinder 24 near the rear of the vehicle cabin. The windward side of the thrust fans 61 is directed in the forward direction of the vehicle cabin 1, and the plurality of thrust fans 61 are uniformly distributed on the input shaft of the generator 62 along the length direction thereof.
