[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 2 As shown, a specific embodiment of the utility model provides a hydrogen dissolving device, including a hydrogen dissolving tank body 1, and an ultrasonic generator 2 and a pressure sensor 3 arranged in the hydrogen dissolving tank body 1. An interface mechanism 4 is provided on one side wall of the hydrogen dissolving tank body 1. The interface mechanism 4 is respectively connected to a pressurized hydrogen supply device 85 and a pressure relief device 6. The pressurized hydrogen supply device 85 is used to supply hydrogen under different pressure states to the hydrogen dissolving tank body 1. The pressure sensor 3 is electrically connected to an external controller 7, and is used to detect the pressure information in the hydrogen dissolving tank body 1 and send it to the external controller 7; the external controller 7 is respectively electrically connected to the ultrasonic generator 2, the pressure relief device 6 and the pressurized hydrogen supply device 85, and is used to control the ultrasonic generator 2, the pressure relief device 6 and the pressurized hydrogen supply device 85 to work according to the pressure signal.

[0023] During the initial hydrogen dissolution operation, the pressure of the hydrogen dissolving tank 1 is relatively low. The external controller 7 controls the operation of the pressurized hydrogen supply device 85 according to the pressure information detected by the pressure sensor 3. The pressurized hydrogen supply device 85 adjusts the input pressure and inputs hydrogen into the hydrogen dissolving tank 1 to maintain the interior of the hydrogen dissolving tank 1 in the required high-pressure state environment. When the hydrogen dissolving tank 1 reaches the required high-pressure state environment, the ultrasonic generator 2 is controlled to vibrate to quickly promote the dissolution of small hydrogen molecules in water under a high-pressure environment, thereby achieving rapid hydrogen dissolution, high hydrogen dissolution efficiency and high hydrogen content, and effectively meeting the high-standard usage requirements of users. Secondly, when the pressure in the hydrogen dissolving tank 1 is too high or the hydrogen dissolution work is completed, the pressure relief treatment can be performed by controlling the pressure relief device 6 to ensure that the hydrogen dissolution work in the hydrogen dissolving tank 1 is stable and safe.

[0024] The ultrasonic generator 2 is arranged at the bottom of the hydrogen dissolving tank 1, and the ultrasonic wave generated can be propagated more evenly and cover the entire solution, and help prevent hydrogen bubbles from gathering at the bottom and reduce the formation of bubble clusters, so as to avoid the bubble clusters affecting the effect of hydrogen dissolution and improve the hydrogen dissolution efficiency and hydrogen content.

[0025] Specifically, the interface mechanism 4 includes an interface mounting plate 41, which is mounted on the outer side wall of the hydrogen dissolving tank body 1, and a hydrogen supply interface component 42 and a pressure relief interface component 43 are installed on the interface mounting plate 41 at intervals; one end of the hydrogen supply interface component 42 and one end of the pressure relief interface component 43 are both connected to the inner cavity of the hydrogen dissolving tank body 1, and the other end of the hydrogen supply interface component 42 is connected to the pressurized hydrogen supply device 85 so that the hydrogen dissolving tank body 1 receives the input hydrogen, and the other end of the pressure relief interface component 43 is connected to the pressure relief device 6 so that when the internal pressure of the hydrogen dissolving tank body 1 is too large or the hydrogen dissolving work is completed, the pressure relief work is performed to improve the safety of use.

[0026] Furthermore, if Figure 3 As shown, the pressurized hydrogen supply device includes a supercharger 51, one end of which is connected to the external hydrogen supply device 8 through an input pipeline, and the other end of which is connected to the hydrogen supply interface component 42 of the interface mechanism 4 through an output pipeline. The supercharger 51 can be set to pressurize the hydrogen dissolving tank 1 to form the required high-pressure state environment, assist in promoting the rapid dissolution of small hydrogen molecules in water, and improve the hydrogen dissolution efficiency.

[0027] Preferably, the pressure relief device 6 includes an electric pressure relief valve, one end of which is connected to the pressure relief discharge pipe, and the other end of which is connected to the corresponding interface component of the interface mechanism 4 through a pressure relief input pipe. When the pressure in the hydrogen dissolving tank 1 is too high or the hydrogen dissolving work is finished, the pressure relief work is realized by controlling the electric pressure relief valve to open the valve, so as to ensure that the hydrogen dissolving tank 1 performs the hydrogen dissolving work in a high-pressure safety environment, and the safety is high. Preferably, in other embodiments, the pressure relief device 6 may also include a manual pressure relief valve, one end of which is connected to the pressure relief discharge pipe, and the other end of which is connected to the corresponding interface component of the interface mechanism 4 through a pressure relief input pipe. The pressure relief function of the hydrogen dissolving tank 1 can also be realized by manually controlling the manual pressure relief valve, so that when the electric pressure relief valve is abnormal, the pressure relief work can be realized through the manual pressure relief valve to protect the hydrogen dissolving tank 1 and further improve the safety of use.

[0028] Preferably, a one-way valve 9 is provided between the supercharger 51 and the hydrogen supply device 8, and the one-way valve 9 is connected to the external controller 7. When the hydrogen dissolving tank 1 needs to supply hydrogen or stops supplying hydrogen, this function can be achieved by controlling the valve opening and closing state of the one-way valve 9 between the supercharger 51 and the hydrogen supply device 8.

[0029] Preferably, if Figure 4As shown, since the pressure inside the hydrogen dissolving tank body 1 is relatively high, in order to ensure the stable operation of hydrogen dissolving and reduce safety hazards, a rotating cover body 11, a flange ring 12, a telescopic driving device 13 and a locking rod 14 are provided at the top opening of the hydrogen dissolving tank body 1; the rotating cover body 11 is used for the hydrogen dissolving tank body 1, and the flange ring 12, the telescopic driving device 13 and the locking rod 14 are used to lock the rotating cover body 11 to prevent leakage or explosion. The edge of the rotating cover body 11 is provided with a protrusion 111, the flange ring 12 is annular, the outer side of the flange ring 12 is fixed on the hydrogen dissolving tank body 1, the inner edge of the flange ring 12 is provided with a limiting groove 121, and the edge of the limiting groove 121 is provided with a mounting notch 122. When sealing, the protrusion 111 can pass through the mounting notch 122 and be screwed into the limiting groove 121 to form a limiting connection. The rotating cover body 11 covers the top opening of the hydrogen dissolving tank body 1, and the limiting groove 121 can limit the rotating cover body 11 in the center line direction of the reaction tank to prevent the rotating cover body 11 from being accidentally opened. The rotating cover body 11 can only be opened when it is rotated to the position where the protrusion 111 corresponds to the mounting notch 122, and then the rotating cover body 11 can be opened. In a further step, in order to prevent the rotating cover body 11 from rotating to the position corresponding to the protrusion 111 and the installation notch 122, the fixed end of the telescopic driving device 13 is fixed to the outer side of the flange ring 12, and one end of the locking rod 14 is connected to the movable end of the telescopic driving device 13. The telescopic driving device 13 can drive the other end of the locking rod 14 to be telescoped in the installation notch 122. When locking, the telescopic driving device 13 drives the locking rod 14 to extend into the installation notch 122. If the rotating cover body 11 rotates, the side of the protrusion 111 will abut against the locking rod 14, so that the rotation of the rotating cover body 11 is hindered, thereby preventing the rotating cover body 11 from being accidentally opened, thereby ensuring the safe operation of the system.

[0030] The telescopic driving device 13 is preferably a driving cylinder, but the present invention is not limited thereto. The movable rod of the driving cylinder is connected to the locking rod 14 to realize the telescopic operation of the locking rod 14 .

[0031] Preferably, in order to ensure safe operation, Figure 4As shown, a locking mechanism 15 is further provided at the top of the hydrogen dissolving tank body 1, and the locking mechanism 15 includes a swing rod 151 and a handle 152. Mounting blocks 123 are respectively provided on both sides of the edge of the flange ring 12, and mounting grooves are provided in the mounting blocks 123. One end of the swing rod 151 is hinged to one of the mounting blocks 123, and the other end of the swing rod 151 is connected to another mounting block 123 through a latch 16. The swing rod 151 can swing around one of the mounting blocks 123 on the top of the flange ring 12, and the latch 16 is used to lock the swing rod 151. After locking, the swing rod 151 cannot swing, and a pull rod 112 is provided on the top of the rotating cover body 11, and the pull rod 112 protrudes from the surface of the rotating cover body 11. The pull rod 112 is in a "door" shape. The number of the pull rods 112 is 2 and they are arranged in parallel, and the swing rod 151 can be inserted between the 2 pull rods 112. When closing, the rotating cover body 11 is rotated by using the pull rod 112 to make the protrusion 111 screwed into the limit groove 121, and make the pull rod 112 parallel to the swing plane of the swing rod 151, and then the swing rod 151 is swung between the two pull rods 112, and the other end of the swing rod 151 is fixed by the pin 16. At this time, if the rotating cover body 11 rotates, the pull rod 112 will abut against the side of the swing rod 151, so that the swing rod 151 can block the rotating cover body 11 from driving the pull rod 112 to rotate, and can further prevent the rotating cover body 11 from opening accidentally. When it is necessary to open the rotating cover body 11, the latch 16 is first pulled out, and then the rocker arm 151 is swung upward. At this time, the restriction of the rocker arm 151 on the pull rod 112 is released, and at the same time, the telescopic drive device 13 drives the locking rod 14 to contract, and the restriction of the locking rod 14 on the protrusion 111 is released. Then, the pull rod 112 is used to rotate the rotating cover body 11 in the opposite direction, so that the protrusion 111 is screwed out of the limiting groove 121, and then the rotating cover body 11 can be pulled out.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
