Description

Technical Field

[0001] This utility model relates to the field of hydrogen refueling station technology, specifically a mobile hydrogen refueling station with a hydrogen storage device. Background Technology

[0002] Hydrogen energy, as the most ideal energy source of the 21st century, is easy to start at low temperatures and has little corrosive effect on the engine, which can extend the engine's service life. Since hydrogen can be mixed evenly with air, the carburetor used in conventional cars can be completely eliminated, thus simplifying the structure of existing cars. Hydrogen refueling stations are gas stations that provide hydrogen to fuel cell vehicles.

[0003] A search revealed CN215174127U, a mobile hydrogen production and refueling station, comprising a support platform, a traction platform, and a connecting mechanism installed on one side of the support platform. The top of the support platform is equipped with a hydrogen production and purification device. An extension block enables the traction platform to drive the support platform, improving the connection speed between the traction platform and the support platform. Operation is simple and convenient. However, the aforementioned hydrogen refueling station connecting mechanism suffers from poor stability. Due to the weight of the hydrogen refueling station, the traction equipment exerts a large pulling force, which can damage the threads of the rotating shaft. Furthermore, the rotating shaft is only fixed at both ends, making it prone to bending and deformation due to the large pulling force. When the rotating shaft is damaged, the rotating block cannot move, preventing the hydrogen refueling station from separating from the traction equipment.

[0004] Based on this, a mobile hydrogen refueling station with a hydrogen storage device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mobile hydrogen refueling station with a hydrogen storage device includes a base, a hydrogen storage tank fixedly installed on the top of the base, and a hydrogen refueling pile fixedly installed on one side of the hydrogen storage tank.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-4 As shown, a mobile hydrogen refueling station with a hydrogen storage device includes a base 1, a hydrogen storage tank 2 fixedly installed on the top of the base 1, and a hydrogen refueling pile 3 fixedly installed on one side of the hydrogen storage tank 2.

[0029] The hydrogen refueling pile 3 has a positioning hole 4 and a stabilizing mechanism 5 on one side, and the base 1 has a connecting mechanism 6 on one side.

[0030] In this embodiment, the connecting mechanism 6 facilitates the connection between the base 1 and the traction device. The movement of the traction device drives the hydrogen refueling station to move. The connecting mechanism 6 has a stable structure and is not easily deformed or damaged during use. The stabilizing mechanism 5 effectively guides the connecting pipe 8. During the hydrogen refueling process using the hydrogen refueling gun 7, the connecting pipe 8 needs to be pulled out from inside the hydrogen refueling pile 3. After refueling, the winding device inside the hydrogen refueling pile 3 winds up the connecting pipe 8. The winding and unwinding of the connecting pipe 8 plays a stabilizing and protective role, extending the service life of the connecting pipe 8.

[0031] In one embodiment, such as Figure 2 As shown, the connecting mechanism 6 includes a second sliding groove 601, which is symmetrically opened on one side of the base 1. A movable seat 602 is slidably mounted on one side of the base 1 via the second sliding groove 601. Fixed plates 604 are fixedly connected to both outer sides of the movable seat 602. A second knob 605 passes through the outer side of the movable seat 602. A threaded hole 603 is opened on one side of the base 1, and the second knob 605 is threadedly connected to the base 1 through the threaded hole 603. A fixed seat 606 is fixedly mounted on one side of the base 1, and the fixed seat 606 is located directly below the movable seat 602. A connecting member 607 is provided between the movable seat 602 and the fixed seat 606. A limiting hole 608 is opened on the top of the connecting member 607. A limiting post 609 is provided inside the limiting hole 608. The limiting post 609 is fixedly connected to the movable seat 602. The top of the movable seat 602 is penetrated by a pin 610, and the bottom of the pin 610 penetrates the connector 607 and the fixed seat 606 respectively. The bottom of the pin 610 has a threaded groove, and the bottom of the pin 610 is threadedly connected to the rotating part 611 through the threaded groove. The connector 607 is fixedly installed with the traction device. When the traction device moves, the connector 607 moves to the top of the fixed seat 606, the fixing plate 604 is loosened, and the movable seat 602 slides downward. The limiting post 609 enters the interior of the limiting hole 608. Then, the fixing plate 604 is threadedly connected to the threaded hole 603 below to fix the movable seat 602. The pin 610 penetrates the movable seat 602, the limiting hole 608 and the fixed seat 606, and the rotating part 611 is used to fix it with the pin 610. This structure is simple, easy to install and disassemble, and has high connection strength and is not easy to deform.

[0032] In one embodiment, such as Figure 3As shown, the stabilizing mechanism 5 includes a fixing frame 501, which is fixedly installed on one side of the hydrogen refueling pile 3. A first sliding groove 502 is formed inside the fixing frame 501. A second slider 504 and a first slider 503 are slidably installed inside the first sliding groove 502. A first guide wheel 506 is rotatably installed on one side of the first slider 503. A spring 505 is fixedly installed between the second slider 504 and the first slider 503. A top plate 507 is fixedly installed on the top of the fixing frame 501. A threaded screw 508 passes through the top of the top plate 507. A first knob 509 is provided on the top of the screw 508. The bottom end of the first knob 509 is rotatably mounted... A connecting plate 510 is fixedly installed between the connecting plate 510 and the second slider 504. By rotating the first knob 509, the screw 508 is driven to rotate, and the rotation of the screw 508 causes the connecting plate 510 to move downward. During this process, the spring 505 is continuously compressed, and the spring 505 continuously provides a downward pressure on the first slider 503. The connecting tube 8 passes between the first guide wheel 506 and the second guide wheel 11. The connecting tube 8 will shake during the retraction and extension process. The spring 505 effectively absorbs the shaking, improves the stability of the connecting tube 8 during retraction and extension, and avoids friction and scratches between the connecting tube 8 and the outside of the hydrogenation pile 3 during the retraction and extension process, which provides a certain degree of protection and extends the service life of the connecting tube 8.

[0033] In one embodiment, such as Figure 3 As shown, a mounting bracket 10 is fixedly installed on one side of the hydrogen refueling pile 3, and the mounting bracket 10 is located directly below the fixed bracket 501. A second guide wheel 11 is rotatably installed on one side of the mounting bracket 10, and the second guide wheel 11 is located directly below the first guide wheel 506. The first guide wheel 506 and the second guide wheel 11 cooperate to provide stable protection for the connecting pipe 8.

[0034] In one embodiment, such as Figure 1 and Figure 4 As shown, a hydrogen refueling gun 7 is provided inside the positioning hole 4. One end of the hydrogen refueling gun 7 is connected to a connecting pipe 8, and one end of the connecting pipe 8 is connected to the hydrogen storage tank 2. When adding hydrogen, hydrogen is introduced into the hydrogen refueling gun 7 through the connecting pipe 8 and finally discharged through the hydrogen refueling gun 7. The positioning hole 4 is designed to facilitate the handling of the hydrogen refueling gun 7.

[0035] In one embodiment, such as Figure 1 and Figure 4 As shown, the bottom of the base 1 is provided with wheels 9, which facilitate the movement of the hydrogen refueling station.

[0036] In one embodiment, such as Figure 4 As shown, support rods 12 are fixedly installed at the four corners of the top of the hydrogen storage tank 2. The support rods 12 are used to support the protective plate 13.

[0037] In one embodiment, such as Figure 1 and Figure 4 As shown, a protective plate 13 is fixedly installed on the top of the support rod 12. The hydrogen refueling station will be used outdoors, and the protective plate 13 will serve to protect against rain and sun.

[0038] The above embodiment discloses a mobile hydrogen refueling station with a hydrogen storage device. The connector 607 is fixed to the traction device by screws. When the traction device moves, the connector 607 moves to directly above the fixed base 606. The fixed plate 604 is loosened, and the mobile base 602 slides downwards, allowing the limiting post 609 to enter the limiting hole 608. The fixed plate 604 is then threaded into the lower threaded hole 603, thus fixing the mobile base 602. A pin 610 passes through the mobile base 602, the limiting hole 608, and the fixed base 606. A rotating part 611 is used to fix the pin 610. The traction device... The hydrogen refueling station moves due to the cooperation of the wheel body 9. By rotating the first knob 509, the screw 508 is rotated, which in turn moves the connecting plate 510 downward. During this process, the spring 505 is continuously compressed, and the spring 505 continuously provides a downward pressure on the first slider 503. The connecting pipe 8 passes between the first guide wheel 506 and the second guide wheel 11. The connecting pipe 8 will shake during the retraction and extension process. The spring 505 effectively absorbs the shaking, improving the stability of the connecting pipe 8 during retraction and extension, and at the same time avoiding friction and scratches between the connecting pipe 8 and the outside of the hydrogen refueling pile 3 during the retraction and extension process.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
