Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production and storage, in particular to a storage rack for hydrogen storage tanks. Background Art

[0002] Hydrogen is the lightest gas known in the world. Its density is very small, only 1 / 14 of air, that is, at standard atmospheric pressure and 0°C, the density of hydrogen is 0.0899g / L. Therefore, hydrogen can be used as the filling gas of airships. Hydrogen is mainly used as a reducing agent. After purification, hydrogen needs to be stored in cans, so a hydrogen tank rack is needed. However, some existing racks only have the function of placement and cannot limit and fix hydrogen tanks of different sizes, which makes it easy for hydrogen tanks to shake in the rack, with poor stability and poor applicability. Utility Model Content

[0003] In view of this, the utility model provides a placement rack for storing hydrogen storage tanks, which can clamp and fix hydrogen tanks of different sizes by driving clamps to approach each other through a driving mechanism, thereby improving the stability of hydrogen tanks during storage and making the device more applicable.

[0004] In order to solve the above technical problems, the utility model provides a storage rack for hydrogen storage tanks, including a rack body, a plurality of guide grooves are evenly opened inside the rack body, two guide columns are slidably arranged on both sides of the guide grooves, a fixed column is arranged at the center of the upper surface of the guide column, a through groove is opened on the upper surface of the rack body and corresponds to the position of the fixed column, the fixed column is slidably arranged in the through groove, a clamping plate is arranged on the upper end of the fixed column, and a driving frame is arranged on the lower surface of the rack body and corresponds to the position directly below the guide groove, and a driving mechanism for driving the two guide columns to approach each other is arranged in the driving frame. The staff places the hydrogen tank to be fixed between the two clamping plates, and then drives the two guide columns to approach each other through the driving mechanism, so that the guide column drives the fixed column to move synchronously, the fixed column slides in the through groove, the fixed column drives the clamping plate to move synchronously, and then the clamping plates are brought close to each other to fix hydrogen tanks of different sizes, thereby improving the stability of the hydrogen tanks during storage and making the device more applicable.

[0005] The driving mechanism includes guide rods arranged on both sides of the driving frame, and rack plates are slidably arranged on the surfaces of the two guide rods. A gear is installed in the center of the driving frame, and the gear is meshed with the rack plates on both sides. A connecting column is arranged on one side of the upper surface of the two rack plates, and a slide groove is opened below the inner wall of the guide groove and corresponding to the position of the connecting column. The connecting column is slidably arranged in the slide groove, and the two connecting columns are respectively fixed on one side of the lower surface of the guide column. A rotating component for driving the gear to rotate is arranged on the lower surface of the driving frame. The staff drives the gear to rotate through the rotating component. Since the gear is meshed with the two rack plates, the rack plate slides along the length direction of the guide rod, so that the rack plates on both sides are driven to move synchronously when the gear rotates. When the two rack plates slide along the guide rod, the two rack plates approach each other, and the rack plate moves, the connecting column moves synchronously, so that the two rack plates move, and the two connecting columns are driven to approach each other, thereby driving the two guide columns to approach each other through the connecting column, so that the clamping plates can be driven to approach each other to clamp and fix the hydrogen tank.

[0006] The rotating assembly includes a spline ring arranged at the center of the lower surface of the driving frame, a spline block is installed inside the spline ring, a connecting frame is arranged at the center of the spline block, a connecting groove is opened inside the connecting frame, a spring is arranged in the connecting groove, the upper end of the spring is fixed to the upper inner wall of the connecting groove, a driving block is fixed to the lower end of the spring, the cross section of the driving block is square, and the cross section of the connecting groove is adapted to the cross section of the driving block, a driving column is arranged at the center of the upper end of the driving block, a through hole is opened on the upper inner wall of the connecting groove and corresponding to the position of the driving column, the upper end of the driving column passes through the through hole of the connecting groove and is connected At the center of the lower end of the gear, a handle is provided at the lower end of the connecting frame. When the hydrogen tank needs to be clamped and fixed, first pull the handle downward to compress the spring. When the connecting frame moves, it drives the spline block to move synchronously, so that the spline block is disengaged from the limit of the spline ring. Then rotate the handle so that the driving column can drive the gear to rotate. When the splint clamps the hydrogen tank, release the handle, and the rebound force of the spring drives the connecting frame to reset, so that the connecting frame drives the spline block to reset, so that the spline block is re-engaged in the spline ring. The limit of the spline ring on the spline block can prevent the connection frame from rotating and causing the spline position to shift.

[0007] The cross-section of the splint is arc-shaped, and limiting gaskets are arranged on both sides of the splint surface, and the limiting gaskets are made of rubber. The splint with an arc-shaped cross-section can better clamp the cylindrical hydrogen tank and improve the clamping effect, while the limiting gaskets made of rubber can prevent damage to the hydrogen tank.

[0008] A pad is provided on the upper surface of the frame and between the two plywood. The pad is made of plastic foam. The staff can place the hydrogen tank on the pad. The pad made of plastic foam can provide shock-proof and buffering effect to the hydrogen tank to a certain extent, thereby improving safety.

[0009] The handle surface is provided with anti-skid threads, which can prevent the hands from slipping.

[0010] Rollers are provided on the two inner walls of the guide groove, and sliders are provided on the two side walls of the guide column. The ends of the sliders are in contact with the surfaces of the rollers. When the guide column moves, the sliders on both sides are driven to move.

[0013] 2. When the utility model is used, the staff drives the gear to rotate through the rotating component. Since the gear is meshed with the two rack plates, the rack plates slide along the length direction of the guide rod, so that the gear rotates and drives the rack plates on both sides to move synchronously. When the two rack plates slide along the guide rod, the two rack plates approach each other. When the rack plates move, they drive the connecting columns to move synchronously, and then when the two rack plates move, they drive the two connecting columns to approach each other, so that the two guide columns are driven to approach each other through the connecting column, so that the clamping plates can be driven to approach each other to clamp and fix the hydrogen tank.
