Description

Technical Field

[0001] The utility model relates to the technical field of plateau oxygen transportation, in particular to a plateau oxygen transportation and supply device. Background Art

[0002] Currently, when tobacco is transported to plateaus, the harshness of the plateau environment must be taken into consideration. Specifically, as altitude increases, atmospheric pressure decreases, and the oxygen content in the air in plateaus is also reduced compared to plains. As the lack of oxygen worsens, people are more likely to experience confusion, low blood pressure, and even coma and difficulty breathing, posing a serious challenge to their health and safety in the plateau environment.

[0003] During tobacco transportation, the cab serves as the driver's environment on the vehicle. When the oxygen concentration in the cab is low, it will cause the driver to experience hypoxia, thereby affecting their safe driving. However, existing drivers often equip their vehicles with oxygen cylinders, and when an oxygen deficiency emergency occurs, they use the oxygen cylinders for emergency oxygen inhalation. However, in this way, the driver cannot inhale oxygen in a timely manner according to the oxygen content of the environment, and the oxygen storage capacity of the oxygen cylinder is limited, and oxygen cannot be supplied continuously, requiring frequent replacement of equipment. Therefore, when transporting in a plateau environment, it is very necessary to ensure that the cab has a certain oxygen content to provide a good air environment for the driver. Utility Model Content

[0004] In response to the above shortcomings, the utility model proposes a plateau oxygen delivery and supply device, which can adjust the oxygen output of the temporary storage box according to the oxygen content in the cab, thereby ensuring a certain oxygen content in the cab and providing a good air environment for the driver.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A plateau oxygen supply device comprises: a cab, wherein the cab is provided with an oxygen sensor; a liquid oxygen tank, wherein the liquid oxygen tank is provided outside the cab, the liquid oxygen tank is connected to a vaporizer via a first pipeline, the output end of the vaporizer is connected to a temporary storage box for accommodating gaseous oxygen, the temporary storage box is built into the cab, the temporary storage box is provided with a plurality of output ports along the same direction, and each output port is correspondingly provided with a switch member; a drive plate, wherein the drive plate is movably provided on the temporary storage box, and the drive plate divides the internal space of the temporary storage box into two sealable cavities, the drive plate is connected to a drive assembly for driving the drive plate to move, the drive assembly is electrically connected to a controller, and the controller is electrically connected to the oxygen sensor; wherein, based on the oxygen concentration in the cab detected by the oxygen sensor, the controller controls the drive assembly to change the movement stroke of the drive plate, and the drive plate drives the switch member in one of the cavities to open or close the corresponding output port.

[0007] The high-altitude oxygen supply device according to the embodiment of the present invention has at least the following beneficial effects: during use, the liquid oxygen in the liquid oxygen tank is vaporized by the vaporizer, causing the liquid oxygen to be converted into gaseous oxygen and flow to the temporary storage tank, which can use one of its sealed cavities to accommodate the gaseous oxygen. When the oxygen sensor detects that the oxygen concentration in the driver's cab is lower than a set value, the controller controls the drive assembly to move the drive plate toward the side away from the oxygen input end of the temporary storage tank, thereby enabling multiple switch components to open corresponding output ports during the movement of the drive plate, thereby increasing the total oxygen output of the temporary storage tank per unit time by increasing the number of output ports. When the oxygen sensor detects that the oxygen concentration in the driver's cab is higher than the set value, the controller controls the drive assembly to drive the drive plate to move in the opposite direction, thereby causing some switch components to close corresponding output ports, thereby reducing the total oxygen output of the temporary storage tank per unit time by reducing the number of output ports. Through the above structure, the oxygen output of the temporary storage tank can be adjusted according to the oxygen content in the driver's cab, thereby ensuring a certain oxygen content in the driver's cab and providing a good air environment for the driver.

[0008] Furthermore, the inner wall of the temporary storage box is provided with a sunken groove connected to the output port, and the switch member is arranged in the sunken groove by pivoting. The switch member includes a first folding plate and a second folding plate connected at an angle, and the side wall of the driving plate is slidably matched with the inner wall of the temporary storage box. The driving plate drives the first folding plate to rotate until it is parallel to and embedded in the sunken groove, and the first folding plate blocks the output port, and the second folding plate is inclined relative to the inner wall of the temporary storage box.

[0009] Furthermore, the pivot is located on one side of the output port, an elastic sleeve is provided on the outer periphery of the first folding plate and the second folding plate, the first folding plate or the second folding plate is embedded in the sink, and the corresponding elastic sleeve is tightly engaged with the inner wall of the sink.

[0010] Furthermore, two opposite inner walls of the sink are provided with clamping grooves, one end of the pivot is telescopically sleeved with a mounting tube, and an elastic member is connected between the mounting tube and the pivot.

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] See also Figures 1 to 4 A plateau oxygen supply device includes: a cab, a liquid oxygen tank and a drive plate 400, the cab is provided with an oxygen sensor; the liquid oxygen tank is provided outside the cab, the liquid oxygen tank is connected to a vaporizer 200 through a first pipeline 100, the output end of the vaporizer 200 is connected to a temporary storage box 300 for accommodating gaseous oxygen, the temporary storage box 300 is built into the cab, and the temporary storage box 300 is provided with multiple output ports 310 along the same direction, each output port 310 is provided with a corresponding switch 320; the drive plate 400 is movable The driving plate 400 is arranged in the temporary storage box 300, and the driving plate 400 divides the internal space of the temporary storage box 300 into two sealable cavities. The driving plate 400 is connected to a driving component for driving its movement, and the driving component is electrically connected to a controller, and the controller is electrically connected to an oxygen sensor. Based on the oxygen concentration in the cab detected by the oxygen sensor, the controller controls the driving component to change the movement stroke of the driving plate 400, and the driving plate 400 drives the switch 320 in one of the cavities to open or close the corresponding output port 310.

[0028] In the high-altitude oxygen supply device described above, when in use, liquid oxygen in the liquid oxygen tank is vaporized by the vaporizer 200, converting the liquid oxygen into gaseous oxygen that flows to the temporary storage tank 300, which can accommodate the gaseous oxygen in one of its sealed cavities. When the oxygen sensor detects that the oxygen concentration in the cab is below a set value, the controller controls the drive assembly to move the drive plate 400 toward a side away from the oxygen input end of the temporary storage tank 300. This causes the multiple switch elements 320 to open corresponding output ports 310 during the movement of the drive plate 400, thereby increasing the total oxygen output of the temporary storage tank 300 per unit time by increasing the number of output ports 310. If the oxygen sensor detects that the oxygen concentration in the cab is above the set value, the controller controls the drive assembly to drive the drive plate 400 in the opposite direction, causing some of the switch elements 320 to close their corresponding output ports 310, thereby reducing the total oxygen output of the temporary storage tank 300 per unit time by reducing the number of output ports 310. Through the above structure, the oxygen output of the temporary storage box 300 can be adjusted according to the oxygen content in the cab, thereby ensuring a certain oxygen content in the cab and providing a good air environment for the driver.

[0029] It is understood that by pre-storing some gaseous oxygen in the temporary storage box 300, the liquid oxygen in the liquid oxygen tank can be vaporized in a corresponding amount of time, thereby ensuring that the gaseous oxygen can be continuously output to the temporary storage box 300. This is conducive to the fact that there is always gaseous oxygen inside the temporary storage box 300 that can be output to the cab, thereby ensuring the oxygen supply in the cab in case of an emergency. In addition, by moving the drive plate 400 to selectively open or close the multiple output ports 310 provided in the temporary storage box 300, not only is the temporary storage and output of oxygen integrated, but the multiple output ports 310 increase the diffusion position of oxygen, thereby accelerating the efficiency of oxygen diffusion in the cab, and can also regulate the oxygen output to ensure a certain oxygen content in the cab.

[0030] See also Figures 1 to 3 Furthermore, the inner wall of the temporary storage box 300 is provided with a recessed groove 311 that communicates with the output port 310. The switch member 320 is rotatably mounted in the recessed groove 311 via a pivot 330. The switch member 320 includes a first folding plate 321 and a second folding plate 322 connected at an angle. The sidewall of the driving plate 400 slides with the inner wall of the temporary storage box 300. The driving plate 400 drives the first folding plate 321 to rotate until it is parallel to and embedded in the recessed groove 311. The first folding plate 321 blocks the output port 310, while the second folding plate 322 is tilted relative to the inner wall of the temporary storage box 300. Specifically, in the initial state, the first folding plate 321 is embedded in the recessed groove 311, and the second folding plate 322 is tilted relative to the inner wall of the temporary storage box 300, thereby achieving the effect of the switch member 320 correspondingly closing the output port 310. When the outlet 310 needs to be opened, the drive plate 400 moves rightward to the position of the second folding plate 322, causing the second folding plate 322 to be deflected by force and engage with the recessed groove 311. This in turn causes the first folding plate 321 to rotate until it no longer blocks the outlet 310, allowing the gaseous oxygen to be output to the cab through the outlet 310. When the output of gaseous oxygen needs to be closed, the drive plate 400 moves leftward to the position of the first folding plate 321, causing the first folding plate 321 to be deflected by force and re-block the outlet 310. This in turn causes the second folding plate 322 to rotate until it is tilted. This structure, which utilizes the rotation of the first and second folding plates 321 and 322 to switch between opening and closing the outlet 310, simplifies the structure and helps reduce equipment costs. It is understandable that when the first folding plate 321 or the second folding plate 322 is engaged with the sink 311 , the corresponding outer surfaces of the two are arranged coplanar with the inner wall of the temporary storage box 300 , which helps to avoid the presence of a step surface between the two and the inner wall of the temporary storage box 300 and thus avoid affecting the movement of the driving plate 400 .

[0031] See also Figures 1 to 3Furthermore, the pivot 330 is located on one side of the output port 310. An elastic sleeve 323 is provided on the outer periphery of the first folding plate 321 and the second folding plate 322. The first folding plate 321 or the second folding plate 322 is embedded in the recess 311, and the corresponding elastic sleeve 323 tightly engages the inner wall of the recess 311. Specifically, the elastic sleeve 323's deformability not only adapts to the space in which the switch member 320 can rotate relative to the recess 311, but also helps to block the clearance between the first folding plate 321 and the output port 310, thereby improving the sealing effect of the first folding plate 321 blocking the output port 310. It is understood that the elastic sleeve 323 can be made of silicone or plastic material, so that the elastic sleeve 323 can be integrally injection molded around the exterior of the switch member 320, improving the connection strength between the two. When the first folding plate 321 or the second folding plate 322 is engaged with the recessed groove 311, the elastic sleeve 323 also helps to improve the tight fit between the first folding plate 321 or the second folding plate 322 and the temporary storage box 300. It is understood that to improve the tight fit between the elastic sleeve 323 and the temporary storage box 300, the sidewalls of the recessed groove 311 extend outwardly with a snap-fitting groove. The elastic sleeve 323 forms a snap fit with the corresponding snap-fitting groove, which helps to maintain the first folding plate 321 or the second folding plate 322 engaged with the recessed groove 311. In some embodiments, two first magnets are spaced apart on the inner bottom wall of the recessed groove 311, and second magnets are respectively provided on the first folding plate 321 and the second folding plate 322. When the first folding plate 321 or the second folding plate 322 is embedded in the recess 311, the second magnet of the first folding plate 321 or the second folding plate 322 is magnetically attracted to and cooperates with the corresponding first magnet, which can also prevent the first folding plate 321 or the second folding plate 322 from detaching from the recess 311, thereby further stabilizing the state of the switch member 320 opening or closing the output port 310.

[0032] See also Figure 2 Furthermore, two opposing inner walls of the sink 311 are provided with slots. One end of the pivot 330 is telescopically fitted with a mounting tube 340. An elastic member is connected between the mounting tube 340 and the pivot 330, allowing one end of the pivot 330 to be telescopically arranged relative to the sink 311, thereby facilitating quick installation of the switch 320. It is understood that the elastic member can be a spring or a plastic member with elastic deformation capabilities, as required, and will not be described in detail here.

[0033] See also Figures 1 to 3Furthermore, the drive assembly includes a motor 410, the output end of the motor 410 is connected to a screw 420, the drive plate 400 is threadedly connected to the screw 420, and the motor 410 is electrically connected to the controller. Based on the oxygen sensor detecting the oxygen concentration in the cab, the controller controls the forward and reverse rotation and speed output of the motor 410, thereby facilitating people to control the movement stroke of the drive plate 400, and facilitating the selective opening or closing of the corresponding output port 310 by linking multiple switch members 320. Among them, the method of using the motor 410 to drive the screw 420 to rotate is conducive to improving the control accuracy of the movement of the drive plate 400. In some embodiments, the drive assembly can also be replaced with a method in which the motor 410 drives the gear rack, which will not be described in detail here.

[0034] In certain embodiments, the temporary storage box 300 includes a built-in limit plate. A displacement sensor is provided on the sidewall of the limit plate facing away from the motor 410. The limit plate is located to the left of the first switch 320 near the motor 410. The drive plate 400 moves rightward starting from the position of the limit plate and moves leftward ending at the position of the limit plate. During operation, when the drive plate 400 moves leftward and reaches the limit plate, the displacement sensor detects the drive plate 400 and generates an electrical signal. This electrical signal is fed back to the controller, which controls the motor 410 to stop, causing the drive plate 400 to stop moving immediately after closing the first switch. This prevents the drive plate 400 from continuing to move and causing a high pressure to build up in the cavity to the left of the drive plate 400.

[0035] See also Figure 1 and Figure 4Furthermore, vaporizer 200 includes an installation box 210, which is equipped with a heating plate 220. A serpentine tube 230 is also installed within installation box 210, communicating with first pipeline 100. First pipeline 100 is equipped with a first on / off valve, and serpentine tube 230 is connected to a second pipeline equipped with a second on / off valve. The output end of the second pipeline is located within a temporary storage box 300. The first on / off valve, the second on / off valve, and heating plate 220 are electrically connected to a controller. Specifically, heating plate 220 heats the interior of installation box 210, and serpentine tube 230 extends the liquid oxygen delivery path, thereby increasing the amount of liquid oxygen vaporized within installation box 210 and facilitating the subsequent output of gaseous oxygen. When the controller activates the drive assembly, it opens the first on-off valve, allowing the liquid oxygen in the liquid oxygen tank to be output to the serpentine tube 230. The liquid oxygen then vaporizes within the serpentine tube 230. The controller then closes the first on-off valve and opens the second on-off valve, allowing the gaseous oxygen to be output to the temporary storage tank 300. To facilitate the flow of liquid oxygen to the serpentine tube 230, a liquid pump is connected between the liquid oxygen tank and the installation box 210. To ensure stable air pressure within the serpentine tube 230, a pressure detector is provided at the output end of the serpentine tube 230. The pressure detector is electrically connected to the controller. This pressure detector measures the air pressure within the serpentine tube 230, allowing the degree of vaporization of the liquid oxygen to be determined while also enabling the controller to promptly open the second on-off valve for pressure relief. It is understood that the first and second on-off valves may be solenoid valves, the specific structures of which are not described in detail herein.

[0036] See also Figure 1 and Figure 4 Furthermore, the temporary storage box 300 is located above the installation box 210, which is conducive to the upward output of gaseous oxygen from the temporary storage box 300. The installation box 210 is provided with a temperature sensor for detecting its internal temperature. The temperature sensor is electrically connected to the controller, thereby improving the temperature control of the temporary storage box 300 through temperature feedback, which is conducive to forming a constant temperature environment inside the installation box 210, so that the vaporizer 200 is suitable for use in plateau and cold areas.

[0037] See also Figure 1 Furthermore, four L-shaped plates 211 distributed in a rectangular shape are provided on the upper surface of the installation box 210. Each L-shaped plate 211 is connected to the top wall of the cab by bolts, so that the gravity of the installation box 210 is evenly distributed by the four L-shaped plates 211, which is beneficial to improving the stability of the installation box 210.

[0038] See also Figure 1Furthermore, the temporary storage box 300 is located in the middle of the top wall of the cab, and multiple output ports 310 are distributed on two opposite side walls of the temporary storage box 300. Each output port 310 is detachably provided with a filter screen, thereby reducing dust from entering the temporary storage box 300. It is understood that the filter screen is provided with filter cotton to filter dust and other impurities in the air.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
