DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1 - Figure 5 The specific implementation modes of the present invention are described in further detail.

[0026] Depend on Figure 1 - Figure 5 As shown, the present invention includes a storage box 1, a delivery pipe 2 for delivering methanol liquid, and a heating cable 3 for heating the delivery pipe 2. In order to achieve a better heating effect on methanol, the heating cable 3 is spirally wound around the middle of the delivery pipe 2. The front side of the storage box 1 is connected to a liquid infusion pipe 4, and the left side of the liquid infusion pipe 4 is connected to a spiral nozzle 5. The liquid infusion pipe 4 is connected to the right side of the delivery pipe 2. The spiral nozzle 5 cooperates with the liquid infusion pipe 4 to form a structure for atomizing the methanol liquid. An adjusting mechanism 6 for adjusting the pitch of the heating cable 3 is respectively provided on the upper and lower sides of the heating cable 3. The adjusting mechanism 6 cooperates with the delivery pipe 2 to form a structure for heating the delivery pipe 2. The spiral nozzle 5 is a prior art, which is a spray nozzle capable of spraying a solid cone or a hollow cone, and will not be described in detail here. When in use, the storage tank 1 is used to store methanol solution for future use. When the methanol fuel engine needs to be started, high-frequency alternating current can be first passed through the heating cable 3. At this time, under the action of hysteresis, the delivery pipe 2 will be heated. When the delivery pipe 2 reaches a certain temperature, the infusion pipe 4 will lead the methanol liquid in the storage tank 1, and then the methanol liquid will be atomized into the delivery pipe 2 under the action of the spiral nozzle 5. Since the delivery pipe 2 has been heated to a certain temperature, the atomized methanol liquid can be quickly heated at this time to enable it to reach a good working temperature. While heating the methanol liquid being transported, the heat of the delivery pipe 2 will also be guided to the storage tank 1. Inside the box 1, the methanol liquid inside the storage box 1 is heated so that the heat can be better utilized. When the temperature of the methanol liquid inside the storage box 1 reaches the preset temperature, the power of the induction heating can be adjusted by reducing the current of the alternating current passing through the heating cable 3, which can not only reduce the overall energy consumption of the device, but also reduce the probability of overheating of the methanol. In addition, when the current control in the heating cable 3 fails in certain circumstances, the pitch of the heating cable 3 can be adjusted through the adjusting mechanism 6, thereby reducing the heating power of the heating cable 3, thereby reducing the probability of overheating of the conveying pipe 2 by the heating cable 3 under abnormal conditions.

[0027] Further, by Figure 1 - Figure 4 As shown, in order to adjust the pitch of the heating cable 3, the adjustment mechanism 6 includes a plurality of cross components 7 connected end to end, each cross component 7 includes a first connecting rod 8 and a second connecting rod 9, and the middle part of each first connecting rod 8 is rotatably connected to the middle part of the corresponding second connecting rod 9 through a rotating pin; When in use, multiple cross components 7 are connected end to end, that is, the rear end of the first connecting rod 8 of the previous cross component 7 is rotatably connected to the front end of the second connecting rod 9 in the next cross component 7. Similarly, the rear end of the second connecting rod 9 of the previous cross component 7 is rotatably connected to the front end of the first connecting rod 8 in the next cross component 7. Under the action of the rotational connection between the middle part of the first connecting rod 8 and the second connecting rod 9 in each cross component 7, the movement amount of the pins in the middle part of the multiple cross components 7 can be increased equidistantly, so that the pitch of the heating cable 3 can be adjusted equidistantly. In addition, since the adjustment mechanism 6 is provided on the upper and lower sides of the heating cable 3, the pitch of the heating cable 3 can be adjusted by force from the upper and lower sides, so that the pitch adjustment of the heating cable 3 is more uniform and stable.

[0028] Further, by Figure 1 - Figure 4As shown, in order to make the thread adjustment of the heating cable 3 more uniform, each rotating pin is rotatably connected to a connecting sleeve 10 on one side close to the heating cable 3, and each connecting sleeve 10 is sleeved on the outside of the heating cable 3 with a gap, and an auxiliary spring 11 is fixedly connected to the outside of the heating cable 3, and the left side of the auxiliary spring 11 is fixedly connected to the delivery pipe 2; During use, when the adjustment mechanism 6 moves, each screw will drive the corresponding position of the heating cable 3 to move through the connecting sleeve 10, so that the heating cable 3 as a whole can maintain the shape of the spiral line and change the pitch. At this time, under the action of the auxiliary spring 11, the position of the heating cable 3 that is not in contact with the connecting sleeve 10 can also maintain the shape of the spiral line as much as possible, reducing the risk of bending or uneven movement.

[0029] Further, by Figure 1 - Figure 4 As shown, in order to preheat methanol, a plurality of first heat conducting sheets 12 are respectively provided on the upper and lower sides of the delivery pipe 2, and a second heat conducting rod 13 is fixedly connected to the side of each first heat conducting sheet 12 away from the delivery pipe 2, and a side of each second heat conducting rod 13 away from the first heat conducting sheet 12 is communicated with the interior of the storage tank 1, and the first heat conducting sheets 12 and the second heat conducting rods 13 cooperate with each other to form a structure for preheating methanol inside the storage tank 1; When in use, the first heat conducting sheet 12 is attached to the outer side of the delivery pipe 2, thereby being able to conduct heat from the delivery pipe 2, and after extending to the inside of the storage box 1 through the second heat conducting rod 13, the methanol solution inside the storage box 1 can be preheated; It should be noted that the second heat-conducting rod 13 passes through the side wall of the storage box 1 and is connected to the interior of the storage box 1, so that the methanol solution inside the storage box 1 can be heated. The second heat-conducting rod 13 has a certain elasticity and can undergo a certain elastic deformation, so that the first heat-conducting plate 12 and the end of the second heat-conducting rod 13 close to the adjustment mechanism 6 can move together with the pin.

[0030] Further, by Figure 1 - Figure 4 As shown, in order to facilitate the operation of the staff, a rotatable adjusting rod 14 is provided on the side of each adjusting mechanism 6 away from the conveying pipe 2, and the right side of each adjusting rod 14 is rotatably connected to the conveying pipe 2, and the right side of each adjusting rod 14 is rotatably connected to a fixing ring 15, and each fixing ring 15 is fixedly connected to the corresponding rotating pin, and the middle part of each adjusting rod 14 is threadedly connected to a moving ring 16, and the side of each moving ring 16 close to the heating cable 3 is fixedly connected to the corresponding rotating pin, and the fixing ring 15 and the moving ring 16 cooperate with each other to form a structure in which the adjusting mechanism 6 is extended; During use, when the adjustment mechanism 6 needs to be operated, the adjustment rod 14 can be rotated. At this time, since the right end of the adjustment rod 14 is rotatably connected to the conveying pipe 2, under the action of the fixing ring 15, the pin position on the far right is fixed. At this time, when the adjustment rod 14 is rotated, the moving ring 16 in the middle of the adjustment rod 14 will move to the left under the action of the threaded cooperation, so that the moving ring 16 can drive the corresponding pin to move to the left, thereby driving the adjustment mechanism 6 to unfold and adjust the structure of the heating cable 3.

[0031] Further, by Figure 1 - Figure 4 As shown, in order to enable automatic adjustment, a large gear 17 is rotatably connected to the middle of the delivery pipe 2, and a small gear 18 is meshed on the upper and lower sides of the large gear 17, and each small gear 18 is fixedly sleeved on the outer side of the corresponding adjustment rod 14. A worm gear 19 is fixedly connected to the left side of the large gear 17, and a worm 20 is meshed on the upper side of the worm gear 19. A motor 21 is fixedly connected to the front side of the storage box 1, and the output end of the motor 21 is fixedly connected to the worm 20. The motor 21 is a servo motor 21, which is a prior art and will not be described in detail here. It should be noted that a hole is provided in the middle of the moving gear and the worm gear 19 for rotationally connecting with the delivery pipe 2; When in use, after starting the motor 21, the motor 21 drives the worm wheel 19 to rotate through the worm 20, and then the worm wheel 19 drives the large gear 17 to rotate. When the large gear 17 rotates, it will drive the two small gears 18 to rotate together, and then drive the two adjusting rods 14 to rotate.

[0032] Further, by Figure 1 - Figure 4 As shown, in order to make the rotation of the adjusting rod 14 more stable, a fixing frame 22 is fixedly sleeved on the outer side of the conveying pipe 2, and a fixing block 23 is fixedly connected to the upper and lower sides of the fixing frame 22. Each fixing block 23 is rotatably connected to the corresponding adjusting rod 14. The fixing frame 22 and the fixing block 23 cooperate with each other to form a rotation limiting structure for each adjusting rod 14.

[0033] Further, by Figure 1 - Figure 4 As shown, in order to atomize and heat the methanol liquid more evenly, an induction heater 24 is commonly connected to both ends of the heating cable 3, an infusion pump 25 is provided inside the storage box 1, the output end of the infusion pump 25 is connected to the infusion tube 4, a conical closing 26 is provided on the left side of the infusion tube 4, and the spiral nozzle 5 is arranged on the left side of the conical closing 26; The induction heater 24 is a prior art, which can generate high-frequency alternating current and heat the metal through hysteresis; the infusion pump 25 is a prior art, which is used to transport the methanol liquid; Further, by Figure 1 - Figure 5 As shown, in order to improve the heating efficiency of the methanol liquid, a blocking block 27 is fixedly connected to the inside of the delivery pipe 2, a conical protrusion 28 is provided on the right side of the blocking block 27, and a plurality of heat conducting rods 29 are provided between the blocking block 27 and the inner side wall of the delivery pipe 2; When in use, the tapered closing mouth 26 can increase the pressure of the methanol liquid when it passes through the spiral nozzle 5, thereby enabling a better atomization effect on the methanol liquid. Since the atomized liquid sprayed out by the spiral nozzle 5 is a hollow cone, under the action of the tapered protrusion 28 and the blocking block 27, a circular conveying channel can be created between the blocking block 27 and the conveying pipe 2, so that the atomized methanol liquid can be conveyed to the methanol fuel engine through the conveying channel. In the conveying channel, the heat conducting rod 29 can improve the heating efficiency of the methanol liquid and increase its heating rate.

[0034] The heating cable 3 includes a plurality of mutually parallel wires 30 and an insulating sheath 31 covering the outer side of the wires 30. The plurality of wires 30 are arranged in a densely packed manner. A plurality of longitudinally arranged graphite interlayers 32 are arranged inside the insulating sheath 31. The longitudinally arranged graphite interlayers 32 form a structure in which two adjacent wires 30 can slide relative to each other. It should be noted that, since graphite is a conductive material, it has good mechanical lubrication ability. When the pitch of the heating cable 3 is changed, the different wires 30 will move relative to each other along the axial direction of the wire 30. At this time, under the action of the graphite interlayer 32, the pitch of the heating cable 3 can be adjusted more easily. It should be noted that the conductors 30 are arranged in the densest packing, that is, in the cross section of the heating cable 3, the outer section of each conductor 30 is tangent to the six adjacent conductors 30, so that the densest arrangement of the conductors 30 within the same cross-sectional area can be achieved, which can also be called "planar hexagonal dense packing".

[0035] When in use, the right side of the delivery pipe 2 is connected to the methanol fuel engine, and is used to deliver heated methanol liquid to the methanol fuel engine; When the present invention is used, first, the storage tank 1 is used to store the methanol solution for use. When the methanol fuel engine needs to be started, high-frequency alternating current can be first passed through the heating cable 3. At this time, under the action of the hysteresis phenomenon, the delivery pipe 2 will be heated. When the delivery pipe 2 reaches a certain temperature, the infusion pipe 4 will lead the methanol liquid in the storage tank 1, and then the methanol liquid will be atomized into the delivery pipe 2 under the action of the spiral nozzle 5. Since the delivery pipe 2 has been heated to a certain temperature, the atomized methanol liquid can be quickly heated at this time to enable it to reach a good working temperature. While heating the methanol liquid being transported, the heat of the delivery pipe 2 will also be guided To the inside of the storage box 1, the methanol liquid inside the storage box 1 is heated so that the heat can be better utilized. When the temperature of the methanol liquid inside the storage box 1 reaches the preset temperature, the power of the induction heating can be adjusted by reducing the current of the alternating current passing through the heating cable 3, which can not only reduce the overall energy consumption of the device, but also reduce the probability of overheating of the methanol. In addition, when the current control in the heating cable 3 fails in certain circumstances, the pitch of the heating cable 3 can be adjusted through the adjusting mechanism 6, thereby reducing the heating power of the heating cable 3, thereby reducing the probability of overheating of the conveying pipe 2 by the heating cable 3 under abnormal conditions.

[0036] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, a better heating effect of methanol can be effectively achieved, the pitch of the heating cable 3 can be adjusted, and the purpose of making the thread adjustment of the heating cable 3 more uniform is achieved. The function of preheating methanol is added, which is convenient for staff to operate and makes the device run more stably, achieving the purpose of more uniform atomization and heating of methanol liquid and improving the heating efficiency of methanol liquid.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
