[0001] The invention relates to the technical field of plateau oxygen transportation, and in particular to a plateau oxygen transportation and supply device. Background Art
[0002] At present, when tobacco needs to be transported to plateau areas, the harsh plateau environment needs to be taken into consideration. Specifically, as the altitude increases, the atmospheric pressure decreases, and the oxygen content of the air in the plateau area decreases compared to the plains. As the lack of oxygen in the outside world worsens, people are prone to confusion, low blood pressure, and even coma and difficulty breathing in severe cases, which makes people's physical health and life safety face severe challenges in the plateau environment.
[0003] In the process of transporting tobacco, the cab is the environment where the driver is on the vehicle. When the oxygen concentration in the cab is low, it will cause the driver to have an oxygen deficiency reaction, thus affecting his safe driving. However, existing drivers mostly equip their vehicles with oxygen cylinders, and when an oxygen deficiency emergency occurs, they use oxygen cylinders for emergency oxygen inhalation. In this way, the driver cannot inhale oxygen in time according to the oxygen content of the environment, and the oxygen cylinders have a limited amount of oxygen stored, and oxygen cannot be supplied continuously, and the equipment needs to be replaced frequently. Therefore, it is very necessary to ensure that there is a certain oxygen content in the cab under the transportation of the plateau environment, so as to provide a good air environment for the driver.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] See also Figures 1 to 4 A plateau oxygen supply device comprises: a cab, a liquid oxygen tank and a driving plate 400, wherein the cab is provided with an oxygen sensor; the liquid oxygen tank is arranged 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 in the cab, and the temporary storage box 300 is provided with a plurality of output ports 310 along the same direction, and each output port 310 is correspondingly provided with a switch 320; the driving 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; wherein, based on the oxygen concentration in the cab detected by the oxygen sensor, the controller controls the driving component to change the moving stroke of the driving plate 400, and the driving plate 400 drives the switch component 320 in one of the cavities to open or close the corresponding output port 310.
[0028] In the plateau oxygen supply device of the above structure, when in use, the liquid oxygen in the liquid oxygen tank is vaporized by the vaporizer 200, so that the liquid oxygen is converted into gaseous oxygen and flows to the temporary storage box 300, and the temporary storage box 300 can use one of the cavities in a closed state to accommodate the gaseous oxygen. Among them, the oxygen sensor detects that the oxygen concentration in the cab is lower than the set value, and the controller controls the operation of the drive assembly so that the drive plate 400 moves toward the side away from the oxygen input end of the temporary storage box 300, so that the multiple switch components 320 can open the corresponding output ports 310 during the movement of the drive plate 400, and then increase the total output of oxygen in the temporary storage box 300 per unit time by increasing the number of output ports 310. When the oxygen sensor detects that the oxygen concentration in the cab is higher than the set value, the controller controls the drive assembly to drive the drive plate 400 to move in the opposite direction, so that some of the switch components 320 close the corresponding output ports 310, and then reduce the total output of oxygen in the temporary storage box 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 that the cab has a certain oxygen content, thereby providing a good air environment for the driver.
[0029] It is understandable that by storing part of the gaseous oxygen in advance in the temporary storage box 300, the liquid oxygen in the liquid oxygen tank can be vaporized in a corresponding time, thereby ensuring that the gaseous oxygen can be continuously output to the temporary storage box 300, which is conducive to the subsequent temporary storage box 300 always having gaseous oxygen inside that can be output to the cab, thereby ensuring the oxygen supply in the cab in emergency situations. In addition, by moving the drive plate 400 to selectively open or close the multiple output ports 310 opened in the temporary storage box 300, not only the temporary storage and output of oxygen are integrated, the diffusion position of oxygen is increased through the multiple output ports 310, thereby accelerating the efficiency of oxygen diffusion in the cab, and the oxygen output can be regulated 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 sinking groove 311 connected to the output port 310, and the switch member 320 is rotatably arranged in the sinking groove 311 through the pivot 330. The switch member 320 includes a first folding plate 321 and a second folding plate 322 connected at an angle, and the side wall of the driving plate 400 is slidably matched with the inner wall of the temporary storage box 300. The driving plate 400 drives the first folding plate 321 to rotate to be parallel and embedded in the sinking groove 311, and the first folding plate 321 blocks the output port 310, and the second folding plate 322 is inclined 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 sinking groove 311, and the second folding plate 322 is inclined to the inner wall of the temporary storage box 300, so that the switch member 320 can achieve the effect of closing the output port 310 accordingly. When the output port 310 needs to be opened, the driving plate 400 moves rightward to the position of the second folding plate 322, so that the second folding plate 322 is deflected by force to fit in the sink 311, and drives the first folding plate 321 to rotate until it no longer blocks the output port 310, so that the gaseous oxygen is output to the cab through the output port 310. When the output of the gaseous oxygen needs to be closed, the driving plate 400 moves leftward to the position of the first folding plate 321, so that the first folding plate 321 is deflected by force to re-block the output port 310, and drives the second folding plate 322 to rotate to a tilted state. Through the above structure, the first folding plate 321 and the second folding plate 322 are rotated to achieve the switching of opening or closing the output port 310, and the structure is simple, which is conducive to simplifying the equipment cost. 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 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 affect the movement of the driving plate 400 .
[0031] See also Figures 1 to 3, further, the pivot 330 is located at one side of the output port 310, and 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 sink 311, and the corresponding elastic sleeve 323 is tightly engaged with the inner wall of the sink 311. Specifically, the deformation ability of the elastic sleeve 323 is utilized to adapt to the activity space of the switch member 320 to rotate relative to the sink 311, and it is also conducive to blocking the matching gap of the first folding plate 321 rotating to block the output port 310, thereby improving the sealing effect of the first folding plate 321 blocking the output port 310. It can be understood that the elastic sleeve 323 can be made of silicone or plastic material, so that the elastic sleeve 323 can be wrapped on the outside of the switch member 320 by integral injection molding, thereby improving the connection strength between the two. When the first folding plate 321 or the second folding plate 322 is engaged with the sink 311 , the elastic sleeve 323 is also helpful to improve the tight fit between the first folding plate 321 and the second folding plate 322 and the temporary storage box 300 .
[0032] It is understandable that, in order to improve the tight fit between the elastic sleeve 323 and the temporary storage box 300, the side wall of the sink 311 extends outward with a card slot, and the elastic sleeve 323 forms a snap fit with the corresponding card slot, which is conducive to maintaining the state of the first folding plate 321 or the second folding plate 322 being embedded in the sink 311. In some embodiments, two first magnets are arranged at intervals on the inner bottom wall of the sink 311, and the first folding plate 321 and the second folding plate 322 are respectively provided with second magnets. When the first folding plate 321 or the second folding plate 322 is embedded in the sink 311, the second magnet of the first folding plate 321 or the second folding plate 322 is magnetically attracted to the corresponding first magnet, which can also prevent the first folding plate 321 or the second folding plate 322 from being separated from the sink 311, thereby further stabilizing the state of the switch 320 opening or closing the output port 310.
[0033] See also Figure 2 Furthermore, two opposite inner walls of the sink 311 are provided with slots, one end of the pivot 330 is telescopically sleeved with a mounting tube 340, and an elastic member is connected between the mounting tube 340 and the pivot 330, so that one end of the pivot 330 can be telescopically arranged relative to the sink 311, so that people can quickly install the switch 320. It is understandable that the elastic member can be a spring or a plastic member with elastic deformation ability according to needs, which will not be described in detail here.
[0034] See also Figures 1 to 3, further, 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, the motor 410 is electrically connected to the controller, based on the oxygen sensor to detect the oxygen concentration in the cab, the controller controls the forward and reverse rotation and speed output of the motor 410, so that people can control the movement of the drive plate 400, which is conducive to selectively opening or closing 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 by the method of the motor 410 driving the gear rack, which will not be described in detail here.
[0035] In some embodiments, the temporary storage box 300 has a built-in limit plate, and a displacement sensor is provided on the side wall of the limit plate away from the motor 410. The limit plate is located on the left side of the first switch 320 close to the motor 410, and the drive plate 400 moves to the right starting from the position of the limit plate and moves to the left with the position of the limit plate as the end point. When in use, when the drive plate 400 moves to the left to the limit plate, the displacement sensor detects the drive plate 400 and generates an electrical signal, which is fed back to the controller, and the controller controls the motor 410 to stop running, so that the drive plate 400 stops moving in time after closing the first switch, thereby preventing the drive plate 400 from continuing to move and causing a large pressure to be generated in the cavity located on the left side of the drive plate 400.
[0036] See also Figure 1 and Figure 4Further, the vaporizer 200 includes an installation box 210, a heating plate 220 is provided inside the installation box 210, a serpentine tube 230 connected to the first pipeline 100 is provided inside the installation box 210, the first pipeline 100 is provided with a first switch valve, the serpentine tube 230 is connected to a second pipeline with a second switch valve, the output end of the second pipeline is built into the temporary storage box 300, and the first switch valve, the second switch valve and the heating plate 220 are electrically connected to the controller. Specifically, the temperature inside the installation box 210 is heated by the heating plate 220, and the conveying path of the liquid oxygen is extended by the serpentine tube 230, which is conducive to increasing the vaporization amount of the liquid oxygen in the installation box 210, thereby facilitating the subsequent output of the gaseous oxygen. In the process of the controller driving the driving component to operate, the controller opens the first switch valve so that the liquid oxygen in the liquid oxygen tank can be output to the serpentine tube 230, and the liquid oxygen completes the vaporization process in the serpentine tube 230. Then the controller closes the first switch valve and opens the second switch valve so that the gaseous oxygen can be output to the temporary storage box 300. In order to facilitate the liquid oxygen to flow to the serpentine tube 230, a liquid pump is connected between the liquid oxygen tank and the installation box 210. In order to ensure the stability of the air pressure in the serpentine tube 230, a pressure detector is provided at the output end of the serpentine tube 230, and the pressure detector is electrically connected to the controller, so that the air pressure in the serpentine tube 230 is detected by the pressure detector. On the one hand, the vaporization degree of the liquid oxygen can be judged, and on the other hand, the second switch valve can be opened in time by the controller for pressure relief. It can be understood that the first switch valve and the second switch valve can be selected as solenoid valves, and the specific structure is not described in detail here.
[0037] 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 to 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 severe cold areas.
[0038] 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, and 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 improve the stability of the installation box 210.
[0039] See also Figure 1Further, the temporary storage box 300 is located in the middle of the top wall of the cab, and a plurality of 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 net, so as to reduce dust from entering the temporary storage box 300 through the filter net. It is understandable that the filter net is provided with filter cotton, and dust and other impurities in the air are filtered through the filter cotton.
