Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell equipment technology, specifically to a water vapor collection mechanism for a hydrogen fuel cell. Background Technology

[0002] In recent years, the development of hydrogen fuel cell vehicles has increased significantly. During operation, hydrogen fuel cells involve a chemical reaction between hydrogen and oxygen in the presence of a catalyst, with water (water vapor) being the primary byproduct. Inside the cell, water is generated in a gaseous state and may diffuse with the flow of the reactant gases. However, when the humidity in the reactant gases is high or the cell operates at high current for extended periods, liquid water may form inside the cell. This necessitates appropriate gas-liquid separation to prevent negative impacts on cell performance.

[0003] Currently, the water produced during the normal operation of hydrogen fuel cells is directly discharged outside the vehicle, resulting in waste; moreover, the water discharged in winter can easily cause the ground to freeze, posing a safety hazard. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a water vapor collection mechanism for hydrogen fuel cells, which solves the problems mentioned in the background section.

[0008] The arc-shaped plate bulges upward at the center and sinks at both ends. Multiple collectors are connected to the ends of the arc-shaped plate. A water pump is connected to the front of the box and is docked with the collectors.

[0009] Multiple grooves are provided at the bottom of both ends of the arc-shaped plate. The grooves are arranged at equal intervals and steel wires are connected inside the grooves. A detection module is provided at the top of the inner wall of the box. The detection module can emit laser light and direct it toward the steel wires.

[0010] It also includes a water inlet trough, which is placed below the end of the arc-shaped plate, with the water inlet trough and the bottom of the arc-shaped plate in close contact with each other, and the collector connected to the water inlet trough.

[0011] Initially, small water droplets enter the groove and come into contact with the steel wire. The water droplets form a water film at the steel wire. The laser shines on the water film and produces partial reflection. The detection module observes the reflection and feeds the information back to the control module. The control module then starts to operate the water pump slowly.

[0012] Preferably, the collector has a water inlet 1, a water inlet 2, and a cavity. The water inlet 1 and the water inlet 2 are connected to the cavity. The water inlet 1 is connected to the groove, and the water inlet 2 is connected to the water inlet channel. A small impeller is pivotally connected inside the cavity. Small water droplets gather into a small water flow and enter the collector, driving the small impeller to rotate. A thin rope is tied to the top of the inner wall of the cavity, and a small iron ball is fixedly tied to the lower end of the thin rope. The small iron ball can contact the small impeller.

[0013] Preferably, the small impeller shaft is connected to a shaft, which is pivotally connected to the inner wall of the collector cavity. The shaft is fitted with a collar, and a vibration sensing unit corresponding to the shaft is connected to the inner wall of the collector cavity. A spring is connected between the vibration sensing unit and the collar.

The base is placed on the top of the inner wall of the box, the laser emitter is placed at the bottom of the base with the working end of the laser emitter facing the steel wire, and the photosensitive unit is placed at the bottom of the base. The water film reflects the laser light to the photosensitive unit.

[0015] Preferably, the air intake unit includes a support, a torque motor, and a propeller. The support is mounted on the top of the arc-shaped plate, the torque motor is mounted on the top of the housing, the propeller is pivotally connected to the center of the support, and the torque motor drive shaft passes through the housing and is welded to the propeller.

[0016] Preferably, a water pipe is connected to the side of the water pump, and the water pipe connects multiple collectors in series.

[0017] Preferably, the arc-shaped plate divides the housing into upper and lower chambers. The air intake and detection module are located in the upper chamber. The propeller is conical, and the diameter of the propeller gradually decreases from top to bottom. The gas generated by the battery combustion is carried into the upper chamber when the propeller rotates.

[0018] (III) Beneficial Effects

[0019] This invention provides a water vapor collection mechanism for hydrogen fuel cells. It has the following beneficial effects:

[0020] 1. The water vapor collection mechanism of this hydrogen fuel cell includes an arc-shaped plate and a water inlet trough. An air intake section is located above the arc-shaped plate to guide the water vapor generated by battery combustion away from the battery body, preventing liquid water from affecting the battery. The arc-shaped plate and water inlet trough guide liquefied water droplets into the collector, achieving the purpose of collecting liquid water. The arc-shaped plate has grooves with steel wires connected within them. The initial contact between water droplets and the steel wires creates a water film, which, combined with a detection module, senses whether water droplets are entering the grooves.

[0021] 2. The water vapor collection mechanism of this hydrogen fuel cell includes a collector containing small iron balls, a small impeller, a shaft, a collar, a spring, and a vibration sensing unit.

[0031] This invention provides a water vapor collection mechanism for hydrogen fuel cells, such as... Figure 1-8 As shown, the device includes a housing 1, with the battery body installed on the bottom inner wall of the housing 1. A control module is installed on the outside of the housing 1, which is used to control the operation of various electronic components. Since the control module and battery body are conventional technologies, their specific structures and circuit layouts are not described in detail.

[0032] An arc-shaped plate 2 is fixedly installed inside the housing 1. The arc-shaped plate 2 is located above the battery body. A through hole 21 is opened at the center of the arc-shaped plate 2. An air intake part is provided at the top of the arc-shaped plate 2 and directly above the hole 21. The air intake part guides the water vapor produced by battery combustion to the top of the arc-shaped plate 2.

[0033] The arc-shaped plate 2 protrudes upward at its center and sinks at both ends. Multiple collectors 5 are connected to each end of the arc-shaped plate 2. The collectors 5 are embedded in the side of the box body 1. One side of the collector 5 extends into the box body 1 and abuts against the arc-shaped plate 2.

[0034] A water pump 10 is fixedly installed on the front of the housing 1, and the water pump 10 is connected to the collector 5.

[0035] Multiple grooves 22 are provided at the bottom of both ends of the arc-shaped plate 2. The grooves 22 are arranged at equal intervals, and each groove 22 corresponds to a collector 5. Steel wires 6 are welded inside the grooves 22. A detection module is provided on the top of the inner wall of the box 1. The detection module can emit laser light and direct it toward the steel wires 6.

[0036] It also includes a water inlet trough 4, which is fixedly installed below the end of the arc-shaped plate 2, with the water inlet trough 4 and the bottom of the arc-shaped plate 2 in close contact. The collector 5 is connected to the water inlet trough 4.

[0037] Water vapor cools and forms small water droplets that adhere to the top and bottom of the curved plate 2. The small water droplets at the top of the curved plate 2 slide towards both ends and flow into the collector 5 through the groove 22. The small water droplets at the bottom of the curved plate 2 slide towards both ends and enter the collector 5 along the water inlet channel 4.

[0038] When no water droplets are generated, the laser emitted by the detection module enters the groove and is reflected to the inner wall of the side of the housing 1. However, if water droplets are generated, the initially generated droplets slowly enter the groove 22 and come into contact with the steel wire 6. At this time, due to tension, the water droplets form a water film at the steel wire 6.

[0039] The laser beam shines on the water film, producing partial reflection, which then shines onto the top of the inner wall of tank 1. The detection module observes the reflection and sends the information back to the control module, which then starts to operate the water pump 10 slowly.

[0040] Collector 5 has a water inlet 51, a water inlet 52, and a cavity. Water inlet 51 and water inlet 52 are connected to the cavity. Water inlet 51 is connected to the groove 22, and water inlet 52 is connected to the water inlet trough 4. A small impeller 7 is pivotally connected inside the cavity. Small water droplets gather into a small stream and enter the collector 5, driving the small impeller 7 to rotate. A thin rope is tied to the top of the inner wall of the cavity, and a small iron ball 9 is fixedly tied to the lower end of the rope. During the rotation of the small impeller 7, the small iron ball 9 can contact the small impeller 7.

[0041] A shaft 8 is welded to the central end of the impeller 7, and the shaft 8 is pivotally connected to the inner wall of the cavity of the collector 5. A collar 81 is slidably fitted on the outside of the shaft 8, and a vibration sensing unit 83 corresponding to the shaft 8 is fixedly installed on the inner wall of the cavity of the collector 5. A spring 82 is fixedly installed between the vibration sensing unit 83 and the collar 81.

[0042] Working principle: When small water droplets converge into a small stream and enter the collector 5, the small stream drives the small impeller 7 to rotate. The small impeller 7 collides with the small iron ball 9, and the vibration generated by the collision is transmitted to the vibration sensing unit 83 through the spring 82. The vibration sensing unit 83 then feeds back the sensed information to the control module.

[0043] After receiving feedback from the detection module and the vibration sensing unit 83, the control module operates the water pump 10 to extract liquid water.

[0044] The detection module includes a base 11, a laser emitter 12, and a light sensing unit 13. The base 11 is fixedly installed on the top of the inner wall of the housing 1. The laser emitter 12 is fixedly installed on the bottom of the base 11, with the working end of the laser emitter 12 facing the steel wire 6. The light sensing unit 13 is fixedly installed on the bottom of the base 11, and the water film reflects the laser light to the light sensing unit 13.

[0045] The air intake unit includes a support frame 3, a torque motor 31, and a propeller 32. The support frame 3 is welded to the top of the arc-shaped plate 2, and the torque motor 31 is fixedly installed on the top of the housing 1. The propeller 32 is pivotally connected to the center of the support frame 3, and the drive shaft of the torque motor 31 passes through the housing 1 and is welded to the propeller 32.

[0046] A water pipe 101 is fixedly installed on the side of the water pump 10, and the water pipe 101 connects multiple collectors 5 in series.

[0047] The arc-shaped plate 2 divides the housing 1 into upper and lower chambers. The air intake and detection module are located in the upper chamber. The propeller 32 is conical, and the diameter of the propeller 32 gradually decreases from top to bottom. The propeller 32 rotates and the gas generated by the battery combustion is brought into the upper chamber.

[0048] In summary, the water vapor collection mechanism for this hydrogen fuel cell includes an arc-shaped plate 2 and a water inlet trough 4. An air intake section is located above the arc-shaped plate 2 to guide the water vapor generated by battery combustion away from the battery body, preventing liquid water from affecting the battery. The arc-shaped plate 2 and water inlet trough 4 guide liquefied water droplets into the collector 5, achieving the purpose of collecting liquid water. The arc-shaped plate 2 has a groove 22, within which a steel wire 6 is connected. The initial contact between the water droplets and the steel wire 6 creates a water film, which, combined with a detection module, senses whether water droplets are beginning to enter the groove 22.

[0049] Furthermore, a collector 5 is installed, containing a small iron ball 9, a small impeller 7, a shaft 8, a collar 81, a spring 82, and a vibration sensing unit 83. These components work together to detect whether water is entering the collector 5, determining if there is excessive water vapor, and feeding this information back to the control module. The control module then operates the water pump 10 based on the feedback information, thus collecting the water.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
