The collected tail water can be used as a heat dissipation medium for cooling the cooling fins connected to the condensation plate, and can be connected to the external pipe port through the external access pipe, so that the water can be used for other purposes and reused.

[0020] The present invention provides a hydrogen fuel cell tail water collection device, which has the following beneficial effects:

[0021] 1. The present invention expands the contact area with water vapor through the spiral cooling tube, effectively improving the condensation efficiency. At the same time, the cooling tube is driven by the rotation of the wheel, so that the water droplets formed by condensation can be shaken off and collected, preventing a large number of water droplets from hanging on the condensing tube, avoiding obstruction of the contact between the condensing tube and water vapor, and improving the water recovery rate.

[0022] 2. The present invention adopts a micro-power solution to automatically adjust the pumping rate according to the intensity of the use of the hydrogen fuel cell, realizing automatic control. When the hydrogen fuel cell combustion rate is low, the pumping work participation is low, preventing the suction cylinder from being damaged due to vacuum negative pressure. When the hydrogen fuel cell combustion rate is high, the amount of water vapor generated is large, driving multiple power turbines to rotate, providing sufficient power for the rotating rod, and reducing the loss of transmission force. This design enables the system to automatically adjust the working state according to actual needs, improving the adaptability and reliability of the system.

[0023] 3.

[0035] 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.

[0036] Example:

[0037] An embodiment of the present invention provides a hydrogen fuel cell tail water collection device, comprising:

[0038] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 7 The cooling chamber 1 is used as a place for condensing the steam generated by the hydrogen fuel cell. The inner wall of the cooling chamber 1 is rotatably connected to the left and right sides of the inner wall of the cooling chamber 1 with a runner 11. A plurality of cooling pipes 12 are fixedly connected to the adjacent sides of the runners 11 on both sides. The cooling pipes 12 are spirally shaped to expand the contact area with the water vapor, so as to contact with the water vapor generated by the combustion of the hydrogen fuel to condense. The air is poured into the interior of the cooling pipes 12 through the air duct on the left side of the cooling chamber 1 to cool the cooling pipes 12 that perform the water vapor heat exchange and condensation work. The runner 11 drives the cooling pipes 12 to rotate through the drive of the air duct to shake off the water droplets condensed on the surface of the cooling pipes 12. The right side of the cooling chamber 1 is fixedly connected to an air outlet 17, and the air outlet 17 is located on the right side of the right runner 11.

[0039] Please see attached Figure 7 and attached Figure 8 The air inlet channel is mainly composed of an air inlet 13 fixedly connected to the left side of the outer wall of the cooling chamber 1 and an air inlet blade 14 rotatably connected inside the air inlet 13. The right side of the air inlet 13 is rotatably connected to the left side of the left rotating wheel 11. The left bottom end of the cooling chamber 1 is rotatably connected to a gear 15. The outer wall of the left rotating wheel 11 is meshed with the gear 15 through teeth. The air inlet blade 14 and the gear 15 are rotated by a driving source. The driving source is composed of a motor 16 installed at the right end of the bottom side of the fixed frame 3. The driving end of the motor 16, the left side of the air inlet blade 14 and the left side of the gear 15 are connected by three pulleys connected by the inner side of the belt.

[0040] Specifically, the diameter of the gear 15 is smaller than the diameter of the meshing structure formed by the left wheel 11 and the teeth, so that the gear 15 changes speed to transmit the left wheel 11 to prevent the wheel 11 and the connected cooling pipe 12 from rotating too fast. After starting the motor 16, the motor 16 will drive the fan blades 14 and the gears 15 to rotate through three pulleys connected by belts, so that the fan blades 14 will take in air through the air inlet 13 on the bottom side of the air inlet 13, and blow the air into the left opening of the cooling tube 12 on the left wheel 11, so that the air enters the interior of the cooling tube 12 and flows out from the opening on the right, thereby taking away the heat of the cooling tube 12, cooling the cooling tube 12, and the water vapor entering the cooling chamber 1 contacts the outer wall of the cooling tube 12 and the bottom side of the condensation plate 18 to release heat, and liquefy condensation occurs on its surface, and the gear 15 drives the left wheel 11 to rotate, thereby rotating the cooling tube 12 connected thereto, so that the water droplets hanging on the surface of the cooling tube 12 are shaken off and fall on the bottom end of the interior of the cooling chamber 1.

[0041] Please see attached Fig.10 , water collecting chamber 2, the water collecting chamber 2 is fixedly connected to the top side of the cooling chamber 1, and serves as a container for collecting water generated by the hydrogen fuel cell. A condensation piece is arranged inside the cooling chamber 1, and the bottom end of the condensation piece is located on the top side of the cooling chamber 1, and the top end of the condensation piece is located inside the water collecting chamber 2, so as to collect water inside the water collecting chamber 2 as a heat transfer medium, absorb the heat of the condensation piece, and make the bottom side of the condensation piece contact with the steam to assist the condensation work. The condensation piece is composed of a condensation plate 18 fixedly connected to the top side of the inner wall of the cooling chamber 1 and a plurality of heat dissipation fins 19 fixedly connected to the top side of the condensation plate 18, the top end of the heat dissipation fin 19 passes through the bottom side of the inner wall of the water collecting chamber 2, and is located inside the water collecting chamber 2, and the tail water collected inside the water collecting chamber 2 can be used as a heat dissipation medium for cooling the heat dissipation fins 19 connected to the condensation plate 18.

[0042] Please see attached Figure 3 -Attached Figure 5 , a fixing frame 3, the fixing frame 3 is fixedly connected to the rear side of the cooling chamber 1, a plurality of shells 4 are fixedly connected to the top side of the fixing frame 3, a power turbine 5 is rotatably connected inside the shell 4, a rotating rod 6 is rotatably connected to the middle end of the fixing frame 3, the right end of the rotating rod 6 sequentially penetrates the middle ends of the plurality of shells 4 and the right side of the fixing frame 3, and is connected to a suction cylinder, the output end of the shell 4 is connected to the cooling chamber 1 through a connecting pipe 21, and the input end of the shell 4 is externally connected to the exhaust port of the hydrogen fuel cell, so that a large amount of steam generated by the violent reaction of the hydrogen fuel cell is poured into the interior of the shell 4, driving the power turbine 5 to rotate, so as to drive the rotating rod 6 as the power of the suction cylinder, and the condensed water inside the cooling chamber 1 is pumped into the interior of the water collecting chamber 2.

[0043] Please see attached Figure 4 -Attached Figure 6 The suction cylinder is composed of a cylinder body 7, a piston rod 8, a reciprocating screw 9 and a branch pipe 10. The cylinder body 7 fixedly connected to the right side of the fixed frame 3 is slidably connected with the piston rod 8. The rear top end of the piston rod 8 is sleeved on the outer wall of the reciprocating screw 9 rotatably connected to the top side of the cylinder body 7. The right end of the rotating rod 6 is connected to the front end of the reciprocating screw 9 through two mutually meshing bevel gears. The branch pipe 10 fixedly connected to the front end of the cylinder body 7 is provided with two branch ports, one of which is connected to the right bottom end of the cooling chamber 1 through a pipeline, and the other branch port is connected to the right top end of the water collecting chamber 2 through a pipeline. Check valves are installed inside the two branch ports.

[0044] Specifically, the power turbine 5, the rotating rod 6, the bevel gear, the reciprocating screw 9, and the connection between the piston rod 8 and the reciprocating screw 9 are all lubricated to reduce resistance and maximize transmission. The water vapor entering the shell 4 will drive the power turbine 5 to rotate, and then the rotating rod 6 connected to it will rotate synchronously, and then the rotating rod 6 will rotate through two meshing bevel gears to drive the reciprocating screw 9. The rotating reciprocating screw 9 drives the piston rod 8 connected to it to move back and forth, and then the inside of the vacuum cylinder 7 generates suction when the piston rod 8 moves backward to pull. One of the branch ports of the branch pipe 10 is used to pour the water inside the cooling chamber 1 into the inside of the cylinder 7 along the water outlet through a pipeline, and then when the piston rod 8 moves forward, it moves along the branch pipe 10. Another branch port of the branch pipe 10 enters the interior of the water collecting chamber 2. Two one-way valves are used to prevent water from flowing back to ensure that the water in the cooling chamber 1 enters the water collecting chamber 2. The design adopts a micro-power solution. The pumping rate is determined by the intensity of the use of the hydrogen fuel cell. If the combustion rate of the hydrogen fuel cell is low, the degree of participation in the pumping work is low to prevent the suction cylinder from sucking air and causing damage due to vacuum negative pressure. If the combustion rate of the hydrogen fuel cell is high, the amount of water vapor generated by the hydrogen fuel cell is large, and at the same time, multiple power turbines 5 are driven to rotate, so that the rotating rod 6 obtains sufficient power and reduces the loss of transmission force.

[0045] Please see attached Figure 2 -Attached Figure 4 The shell 4 is in an inclined state, and both the output end and the input end of the shell 4 are in an inclined state. The opening of the output end is inclined downward to prevent water vapor from accumulating inside the shell 4 when condensation occurs inside the shell 4. The connecting pipe 21 is also in an inclined state, which is also used to prevent liquid water from condensing and accumulating in the connecting pipe 21, and guide the water into the cooling chamber 1.
