Description

Technical Field

[0001] The invention relates to the field of hydrogen production equipment, and in particular to a hydrogen collection device for producing hydrogen by electrolysis of water. Background Art

[0002] The technology of producing hydrogen by electrolysis of water is crucial to the use of clean and sustainable energy in the future. The technology of producing hydrogen by electrolysis of water is to dissociate water molecules into hydrogen and oxygen through an electrochemical process under the action of direct current, and precipitate them at the cathode and anode respectively.

[0003] In the prior art, in the process of producing hydrogen by water electrolysis, hydrogen storage tanks are often used for collection. However, the storage capacity of hydrogen storage tanks is limited and the weight is large, which makes it very laborious to carry. In the prior art, a conveyor is usually used to transport the hydrogen storage tank to the position of the hydrogen discharge end, and then the hydrogen discharge end is connected to the hydrogen storage tank to achieve hydrogen collection.

[0004] During the docking process, it is necessary to ensure that the hydrogen storage tank and the hydrogen discharge port end are tightly connected to prevent hydrogen leakage. This requires that the hydrogen storage tank must be transported to the designated location each time. If the transportation position of the hydrogen storage tank deviates slightly, it will make it difficult to dock the hydrogen discharge end with the hydrogen storage tank, thereby increasing the difficulty of collection.

[0005] To this end, the present invention proposes a hydrogen collection device for producing hydrogen by electrolysis of water to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hydrogen collection device for producing hydrogen by electrolyzing water.

[0007] In order to achieve the above purpose, the technical solution adopted by the present invention is: a hydrogen collection device for producing hydrogen by electrolysis of water, comprising:

DETAILED DESCRIPTION

[0068] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0069] like Figures 1 to 13 A hydrogen collection device for producing hydrogen by electrolysis of water is shown, comprising:

[0070] A hydrogen tank 1, the top of which is fixedly connected with a first pair of joints 2;

[0071] The conveying pipe 3, the bottom end of which is slidably connected to a connecting pipe 5 through a lifting mechanism, and a through groove 501 is provided at the bottom end of the connecting pipe 5;

[0072] A second pair of joints 6, the second pair of joints 6 are slidably connected in the through groove 501;

[0073] A butt joint pipe 7, which is fixedly connected to the outer side wall of the bottom end of the second butt joint 6, and has a guide opening 701 at the bottom end of the butt joint pipe 7;

[0074] A plurality of elastic telescopic rods 8 are arranged in a circular array on the bottom end of the outer side of the connecting tube 5, one end of the elastic telescopic rod 8 is rotatably connected to the bottom end wall of the outer side of the connecting tube 5, and the other end is rotatably connected to the side wall of the second pair of joints 6;

[0075] During the docking process, if the first pair of joints 2 deviates from the specified position, the top of the first pair of joints 2 first contacts with the guide opening 701 and is squeezed, and under the action of the elastic telescopic rod 8, the second pair of joints 6 automatically adjusts its position according to the force direction to adapt to the position of the first pair of joints 2 for docking;

[0076] Specifically, in the prior art, during the docking process, it is necessary to ensure that the hydrogen storage tank and the end of the hydrogen discharge port are tightly connected after docking to prevent hydrogen leakage, which requires that the hydrogen storage tank must be transported to a designated position each time. If the transportation position of the hydrogen storage tank deviates slightly, it will cause the hydrogen discharge end to be difficult to dock with the hydrogen storage tank, thereby increasing the difficulty of collection. The technical solution can solve the above problem. The specific operation is as follows: the hydrogen tank 1 is transported to the bottom of the second docking joint 6 by a conveying device such as a conveyor belt or a mechanical arm, and then the connecting pipe 5 drives the second docking joint 6 to move downward through the lifting mechanism, so that the second docking The first pair of joints 6 is close to the first pair of joints 2. If there is an error in the position of the first pair of joints 2, during the downward movement of the second pair of joints 6, the top of the first pair of joints 2 will first contact the inside of the guide port 701 and squeeze the inside of the guide port 701, so that the butt joint 7 is stressed. Since the butt joint 7 is fixed to the second pair of joints 6, when the butt joint 7 is stressed, the second pair of joints 6 will automatically adjust its position according to the direction of the force to adapt to the position of the first pair of joints 2, so that the first pair of joints 2 can be accurately inserted into the position between the butt joint 7 and the second pair of joints 6, and the butt joint with the second pair of joints 6 is completed, thereby reducing the difficulty of butt jointing, which is conducive to the collection of hydrogen by the hydrogen tank 1;

[0077] During the process of the second pair of joints 6 moving and adjusting the position, the plurality of elastic telescopic rods 8 undergo corresponding elastic deformation. When the hydrogen collection is completed and the first pair of joints 2 and the second pair of joints 6 are unmated, the second pair of joints 6 are reset under the elastic action of the elastic telescopic rods 8 to prepare for the next docking.

[0078] The present invention provides a plurality of elastic telescopic rods 8 and a slidable second pair of joints 6, so that the second pair of joints 6 can be autonomously adjusted according to the position of the first pair of joints 2 during the docking process of the hydrogen tank 1, so that the hydrogen tank 1 can be successfully docked with the second pair of joints 6 within a specified range, thereby improving the success rate of docking and reducing the difficulty of the hydrogen tank 1 in collecting hydrogen.

[0081] Specifically, by setting the cylinder 4, when the hydrogen tank 1 is transported to the right below the second pair of joints 6, the cylinder 4 is started to move the telescopic rod of the cylinder 4 downward, so that the second pair of joints 6 moves downward and approaches the first pair of joints 2. Under the above principle, the first pair of joints 2 and the second pair of joints 6 are docked;

[0082] After the hydrogen collection is completed, the cylinder 4 is started, so that the telescopic rod of the cylinder 4 moves downward, thereby causing the second pair of joints 6 to move upward, thereby canceling the docking effect with the first pair of joints 2.

Then the solenoid valve 24 is started to open the bottom end of the pipe 10, so that hydrogen is injected into the hydrogen tank 1. When the collection of the hydrogen tank 1 is completed, the solenoid valve 24 is closed first to seal the bottom of the pipe 10. Then, the cylinder 4 is used to move the pipe 10 away from the first pair of joints 2, and the squeezing effect on the flip sealing plate 25 is cancelled. Under the action of the torsion spring 26, the flip sealing plate 25 is reset to seal the top of the hydrogen tank 1 to prevent hydrogen leakage.
