Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle compartment gas detection, in particular to a vehicle compartment abnormal gas gathering detection device during driving. BACKGROUND

[0002] In today's high-speed development of the logistics industry, the types of road transport goods are numerous, and accidents such as toxic and harmful gas leakage and goods spontaneous combustion may occur. In order to discover the accident precursors in time during the driving of the truck transporting goods, it is often necessary to install a gas detector in the vehicle compartment, so that the driver can know whether there is abnormal gas in the vehicle compartment in time, stop the vehicle for inspection in time, and take measures to prevent accidents. However, due to the relatively closed truck compartment and the close stacking of goods, the air circulation is poor, and the initial abnormal gas outflow often accumulates near the outflow. When the abnormal gas appears near the gas detector, the generation or leakage of the abnormal gas is difficult to control.

[0003] At present, there is no device for detecting abnormal gas gathering in the vehicle compartment. In the prior art, the patent for invention with patent number CN104730119A provides a vehicle compartment gas detection method, which does not involve how to strengthen the collection of CO and other abnormal gases in the vehicle; the patent for invention with patent number CN108808045A provides a long-pipe trailer compartment flammable gas leakage detection device, which detects whether there is flammable gas leakage by setting a gas storage pipe and checking the consumption of oxygen in the gas storage pipe, but does not involve how to accelerate the collection of flammable gas and improve the detection efficiency. SUMMARY

[0004] In view of the deficiencies in the above background art, the present application provides a vehicle compartment abnormal gas gathering detection device during driving, which sets a gathering cylinder and a gas detection device on the vehicle compartment, uses Bernoulli's principle to extract the gas in the vehicle compartment, and promotes the gas in the vehicle compartment to gather in the gathering cylinder, so as to realize efficient and rapid detection of the gas in the vehicle compartment and discover the abnormal gas in the vehicle compartment as soon as possible.

[0005] The technical scheme of the present application is as follows:

[0006] A vehicle compartment abnormal gas gathering detection device during driving, comprising a gathering cylinder arranged on the top of the vehicle compartment, a gathering channel is formed in the gathering cylinder through a gathering plate, an installation hole communicating with the inside of the vehicle compartment is formed at the bottom of the gathering channel, an installation cylinder is arranged in the installation hole, one end of the installation cylinder extends into the inside of the vehicle compartment, and a gas detection device is arranged in the installation cylinder through an installation plate.

[0007] Further, the gathering plate is provided with two pieces, the two pieces of gathering plates are arranged oppositely, and the gathering channel formed by the two pieces of gathering plates in the horizontal plane is a sandglass-shaped channel with wide ends and narrow middle.

[0008] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0009] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0010] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0011] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0012] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0013] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0014] Further, the dustproof frame is arranged on one end of the gathering cylinder, which is directed to the advancing direction of the vehicle cabin, a plurality of support rods are arranged in the dustproof frame at equal intervals, and a dustproof net is attached to the side of the plurality of support rods, which is directed to the outside of the gathering cylinder.

[0016] The beneficial effects of the present application are as follows:

[0017] 1. During vehicle operation, the air entering the collecting channel is concentrated into a narrower channel, increasing the airflow velocity. According to Bernoulli's principle, the faster the fluid flows, the lower the pressure inside the fluid. This results in a larger pressure difference between the collecting cylinder and the vehicle compartment, accelerating the airflow from the compartment through the mounting cylinder and into the collecting cylinder. This allows the gas detection device inside the mounting cylinder to detect the gas more quickly and efficiently. When abnormal gas is present, the gas detection device will alarm, alerting the driver in advance to the gas situation in the vehicle compartment and preventing potential problems.

[0018] 2. The streamlined design of the collecting cylinder can reduce wind resistance, thereby reducing the energy consumption of the vehicle by the present invention.

[0019] 3. The inclusion of inspection ports makes it easier for people to repair or replace gas detection devices.

[0020] 4. The dustproof net can prevent foreign objects from entering the dust collection cylinder during vehicle operation and under normal ventilation conditions. The secondary dust baffle can prevent foreign objects from entering the compartment from the installation cylinder, reducing damage to the goods inside the compartment.

[0021] 5. The rainwater diversion component can prevent rainwater from entering the interior of the carriage through the collection cylinder, thus avoiding damage to the goods inside the carriage.

[0022] 6. The generator can provide power to the gas detection device. At the same time, the charging interface on the energy storage power supply can be electrically connected to an external charging device, thereby ensuring sufficient power supply to the energy storage power supply and ensuring the normal operation of the gas detection device. Moreover, the generator increases the utilization rate of wind energy and reduces the energy supply requirements of the invention to the vehicle. Attached Figure Description

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the application.

[0033] Embodiment 1

[0034] Referring to Figure 1 and Figure 2 A vehicle cabin abnormal gas collection detection device during driving includes a collection cylinder 2 arranged at the top of the vehicle cabin 1, and two collection plates 21 are fixed in the collection cylinder 2. The collection plates 21 can be selected as folded plates or arc-shaped plates. The two collection plates 21 are arranged oppositely on the same horizontal plane to form a collection channel 22 with a sandglass shape of wide ends and narrow middle. In this embodiment, the collection plates 21 are folded plates. During driving of the vehicle, the wind entering the collection channel 22 can be collected into the relatively thin channel formed by the two collection plates 21, so as to improve the flow rate of the wind.

[0035] Referring to Figure 3 and Figure 4The bottom of the gathering channel 22 is provided with a mounting hole 23 communicating with the inside of the carriage 1, and the mounting hole 23 is located in the middle of the gathering channel 22. A through hole corresponding to the mounting hole 23 is formed in the top of the carriage 1, and a mounting cylinder 24 is arranged in the mounting hole 23. The mounting cylinder 24 is detachably mounted on the inner cylinder wall of the bottom side of the gathering cylinder 2 by bolts. One end of the mounting cylinder 24 penetrates the through hole and extends to the inside of the carriage 1. A vertically arranged mounting plate is fixed in the mounting cylinder 24 and located at the middle position of the mounting cylinder 24. The gas detection device 3 is detachably mounted on the mounting plate by bolts.

[0036] The gas detection device 3 is a waterproof fixed type detection device with an alarm. Further, a corrosion and waterproof gas detection alarm instrument disclosed in Chinese patent CN210109998U can be selected. When the gas detection alarm instrument is selected, the wall fixing seat of the gas detection alarm instrument is fixed on the mounting plate by screws, and the gas inlet pipeline of the gas detection alarm instrument faces the inside of the carriage 1.

[0037] Referring to Figure 4 and Figure 5 During vehicle driving, the wind accelerated by the gathering cylinder 2 flows above the mounting cylinder 24. According to Bernoulli's principle, the faster the flow rate of the fluid, the smaller the pressure in the fluid. Therefore, during vehicle driving, the gathering cylinder 2 is in a negative pressure state, and the pressure in the carriage 1 is relatively large at this time. The gas in the carriage 1 is drawn into the gathering cylinder 2 from the mounting cylinder 24, and the gas flowing through the mounting cylinder 24 is detected by the gas detection device 3, so as to judge whether it is abnormal gas. When abnormal gas is found, the gas detection device 3 with an alarm function will issue a warning to the driver, so as to let the driver discharge the dangerous factor in advance.

[0038] Since the gathering cylinder 2 gathers the wind outside the carriage 1 into a channel with a smaller cross-sectional area, the wind speed is larger than that outside the gathering channel 22, so that the pressure difference between the carriage 1 and the gathering cylinder 2 is also larger, so that the gas in the carriage 1 can flow to the gathering cylinder 2 more quickly, and the gas detection device 3 can contact the gas in the carriage 1 earlier. Compared with the general gas detection device 3 installed in the inside of the carriage 1, the gas in the carriage 1 can be judged more quickly and efficiently. At the same time, the accelerated outflow of the gas in the inside of the carriage 1 relies on the physical principle, and does not need additional gas extraction equipment, which reduces the additional energy consumption.

[0039] Referring to Figure 1 and Figure 4The top of the collecting cylinder 2 is provided with an inspection hole 26, the diameter of the inspection hole 26 is larger than that of the mounting hole 23, and the inspection hole 26 is coaxially arranged corresponding to the mounting hole 23. The top surface of the collecting cylinder 2 is provided with a detachable cover plate 27 for closing the inspection hole 26. The cover plate 27 is mounted on the top of the collecting cylinder 2 by bolts. When it is necessary to maintain or replace the gas detection device 3, the cover plate 27 is removed, and the gas detection device 3 can be easily removed from the mounting cylinder 24, which is convenient for the maintenance of the gas detection device 3.

[0040] Embodiment 2

[0041] This embodiment is a further improvement based on embodiment 1.

[0042] With reference to Figure 1 and Figure 6 In this embodiment, the end of the collecting cylinder 2 facing the forward direction of the vehicle compartment 1 is an arc-shaped end, and the end is provided with a dustproof frame 41 matched with the arc-shaped end. A plurality of support rods 42 are arranged in the dustproof frame 41, the support rods 42 are arc-shaped rods matched with the arc-shaped frame, the plurality of support rods 42 are arranged transversely and uniformly distributed along the arc length of the end of the collecting cylinder 2. A dustproof net 43 is attached to one side of the plurality of uniformly distributed support rods 42 facing the outside of the collecting cylinder 2. The dustproof net 43 can prevent foreign matter from entering the collecting cylinder 2 under the condition of normal ventilation of the collecting cylinder 2 during the driving of the vehicle.

[0043] With reference to Figure 4 , the mounting cylinder 24 is provided with a secondary dust baffle 44 at the cylinder opening of the end facing the collecting channel 22, and the secondary dust baffle 44 can prevent foreign matter from entering the vehicle compartment 1 from the mounting cylinder 24.

[0044] Embodiment 3

[0045] This embodiment is a further improvement based on embodiment 1 or embodiment 2.

[0046] With reference to Figure 4 and Figure 7In the embodiment, the rainwater diversion assembly 5 is detachably arranged at the end of the mounting cylinder 24 away from the collecting cylinder 2, i.e., the end extending into the carriage 1. The rainwater diversion assembly 5 comprises a foreign matter blocking cylinder 51, a collecting hopper 52, and a diversion pipe 53. The foreign matter blocking cylinder 51 is provided with a plurality of air vents 511 on the cylinder wall, which can prevent foreign matters in the carriage 1 from entering the foreign matter blocking cylinder 51 and ensure the normal flow of air in the carriage 1 into the mounting cylinder 24. The foreign matter blocking cylinder 51 is sleeved on the end of the mounting cylinder 24 extending into the carriage 1 and detachably connected to the mounting cylinder 24 by bolts. The collecting hopper 52 is arranged at the bottom of the foreign matter blocking cylinder 51, the large end of the collecting hopper 52 is fixedly connected to the bottom of the foreign matter blocking cylinder 51, the small end, i.e., the discharge end of the collecting hopper 52 is fixedly connected to one end of the diversion pipe 53, and the end of the diversion pipe 53 away from the collecting hopper 52 extends to the outside of the carriage 1.

[0047] When it rains, during the travel of the vehicle, due to the fast air flow above the mounting cylinder 24, very little rainwater enters the mounting cylinder 24, but it is still not guaranteed that rainwater will flow into the mounting cylinder 24 from the collecting cylinder 2. When rainwater flows into the mounting cylinder 24, the rainwater flowing into the mounting cylinder 24 will pass through the mounting cylinder 24 and the foreign matter blocking cylinder 51 and fall into the collecting hopper 52, and then be diverted to the outside of the carriage 1 under the action of the diversion pipe 53, avoiding the rainwater directly falling into the carriage 1 and avoiding the damage of the rainwater to the goods.

[0048] Embodiment 4:

[0049] The embodiment is a further improvement based on the embodiments 1, 2 or 3.

[0050] With reference to Figure 2 and Figure 3 In the embodiment, the collecting cylinder 2 is provided with a power generation mechanism 6, which comprises a thrust fan 61, a generator 62, and an energy storage power supply 63. Two energy storage cavities 7 are formed between the two collecting plates 21 and the two side walls of the collecting cylinder 2, and the generator 62 is installed in one of the energy storage cavities 7. The generator 62 is located at the side of the mounting cylinder 24 close to the tail of the carriage, the input shaft of the generator 62 is parallel to the transverse direction of the carriage, and the input shaft of the generator penetrates through the two collecting plates 21 and is rotationally connected to the corresponding collecting plate 21 through a bearing.

[0051] The thrust fan 61 is arranged in the collecting channel 22 and installed on the input shaft of the generator 62. The thrust fan 61 can be provided in plurality, and the plurality of thrust fans 61 are located at the side of the mounting cylinder 24 close to the tail of the carriage. The windward surface of the thrust fan 61 faces the advancing direction of the carriage 1, and the plurality of thrust fans 61 are uniformly distributed along the length direction of the input shaft of the generator 62. During the travel of the vehicle, the wind flowing through the collecting cylinder 2 can drive the thrust fan 61 to rotate, thereby driving the generator 62 to generate electricity.

[0052] The energy storage power supply 63 is installed in the energy storage cavity 7, and the generator 62 and the gas detection device 3 are electrically connected with the energy storage power supply 63. The generator 62 stores the electric energy into the energy storage power supply 63 through rectifying elements, and the energy storage power supply 63 can supply the electric power for the gas detection device 3, so as to ensure the normal operation of the gas detection device 3.

[0053] In addition, the energy storage power supply 63 is also provided with a charging interface (not shown in the figure) which can be connected with an external charging device, so as to ensure the sufficient electric power of the energy storage power supply 63 and the normal operation of the gas detection device 3. At the same time, the setting of the generator 62 also increases the utilization rate of the wind energy and reduces the demand for the energy supply of the vehicle.

[0054] The above only describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
