[0001] This invention relates to the field of skid-mounted refueling equipment technology, specifically to a shock-resistant and explosion-proof skid-mounted refueling device. Background Technology

[0002] Skid-mounted gas stations are not gas stations in the traditional sense. They are mobile stations that mainly consist of oil storage tanks, fuel dispensers, and automatic fire extinguishers, and have advantages over traditional gas stations in terms of land area and construction time.

[0003] Once installed, a skid-mounted gas station is essentially a small structure. In cities located on earthquake zones, the seismic resistance of such a small structure must be considered when setting up a skid-mounted gas station.

[0004] Existing skid-mounted refueling units have unsatisfactory earthquake resistance. When the tank is subjected to seismic waves, the unit is easily damaged by vibration, affecting the normal use of the refueling unit. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a shock-resistant and explosion-proof skid-mounted refueling device, aiming to solve the technical problem mentioned in the background art that the existing skid-mounted refueling devices have unsatisfactory earthquake resistance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shock-resistant and explosion-proof skid-mounted refueling device, comprising a refueling machine, an unloading pump, and a barrier explosion-proof double-layered oil storage tank. The refueling machine and the unloading pump are both located at one end inside the shock-resistant frame. The outer side of the barrier explosion-proof double-layered oil storage tank is located inside the shock-resistant frame through multiple oil tank shock-resistant units. The bottom surface of the shock-resistant frame is located on the top surface of the seismic isolation base. The bottom surface of the seismic isolation base is located in the middle of the top surface of the main base. Protective weirs are provided on the outer side of the seismic isolation base and the top surface of the main base.

[0007] Furthermore, the seismic-resistant frame includes a frame body, a frame base plate at the bottom of the frame body, a refueling machine and an unloading pump at one end of the frame base plate, and seismic-resistant frame units at both ends of the frame body.

[0008] Furthermore, the frame seismic unit includes a viscous damper. One end of the viscous damper is rotatably connected to a damping mounting upper seat, the top surface of which is located at the upper part of one end of the frame body. The other end of the viscous damper is rotatably connected to a damping mounting lower seat, the bottom surface of which is located at the lower part of one end of the frame body. One side of the viscous damper is provided with an inner sealing plate, and the other side of the viscous damper is provided with an outer sealing plate. A damper inspection port is embedded in the middle of the outer sealing plate.

[0009] Furthermore, the oil tank seismic unit includes an oil tank fixing frame, the inner side of which is located on the outer side of the barrier explosion-proof double-layer oil storage tank. The four corners of the oil tank fixing frame are respectively provided with sliding limiting angles, and the multiple sliding limiting angles are slidably connected to the middle of the seismic frame. Multiple seismic support units are symmetrically provided on both sides of the oil tank fixing frame, and one side of each of the multiple seismic support units is located on both sides of the middle of the seismic frame.

[0010] Furthermore, the seismic support unit includes a double-linked fixing member. One side of the double-linked fixing member is located on one side of the middle portion of the seismic frame. The two ends of the double-linked fixing member are respectively rotatably connected to one end of a first support energy dissipation damper. The other end of the first support energy dissipation damper is rotatably connected to one end of a second support energy dissipation damper and one end of an auxiliary support connecting rod. The other end of the second support energy dissipation damper is rotatably connected to one end of the support fixing member. One side of the support fixing member is located on one corner of the oil tank fixing frame. The other end of the auxiliary support connecting rod is rotatably connected to one end of a connecting rod fixing member. One side of the connecting rod fixing member is located on one side of the middle portion of the seismic frame.

[0011] Furthermore, the seismic isolation base includes a seismic isolation raised seat, the bottom surface of which is located in the middle of the top surface of the main base. The top surface of the seismic isolation raised seat is provided with multiple lead-core rubber seismic isolation supports, the top surfaces of which are all located on the bottom surface of the seismic isolation movable seat surface. The top surface of the seismic isolation movable seat surface is provided with the seismic-resistant frame.

[0012] Furthermore, water-retaining side panels are provided around the bottom surface of the seismic isolation movable seat, and the height of the water-retaining side panels from the ground is less than or equal to half the height of the seismic isolation raised seat.

[0033] For an embodiment, please refer to Figures 1-2. A shock-resistant and explosion-proof skid-mounted refueling device includes a refueling machine 1, an unloading pump 2, and a barrier explosion-proof double-layer oil storage tank 3. The refueling machine 1 and the unloading pump 2 are both located inside one end of the shock-resistant frame 4.

The fuel dispenser 1 and the unloading pump 2 are located at one end of the frame base plate 42. Seismic-resistant frame units 43 are provided at both ends of the frame body 41.

The viscous damper 431 can be inspected and maintained through the damper inspection port 436.

[0035] In this embodiment, please refer specifically to Figures 5-6. The oil tank seismic unit 5 includes an oil tank fixing frame 51. The inner side of the oil tank fixing frame 51 is located on the outer side of the explosion-proof double-layer oil storage tank 3.

One side of each seismic support unit 53 is located on both sides of the middle of the seismic frame 4. Each seismic support unit 53 includes a double-jointed fixing member 531. One side of the double-jointed fixing member 531 is located on one side of the middle of the seismic frame 4. The two ends of the double-jointed fixing member 531 are rotatably connected to one end of the first support energy dissipation damper 532. The other end of the first support energy dissipation damper 532 is rotatably connected to one end of the second support energy dissipation damper 533 and one end of the auxiliary support connecting rod 534. The other end of the second support energy dissipation damper 533 is rotatably connected to one end of the support fixing member 535. One side of the support fixing member 535 is located on one corner of the oil tank fixing frame 51. The other end of the auxiliary support connecting rod 534 is rotatably connected to one end of the connecting rod fixing member 536. One side of the connecting rod fixing member 536 is located on one side of the middle of the seismic frame 4. Multiple seismic support units 53 form a support through multiple support energy dissipation dampers and auxiliary support connecting rods 534. With the sliding cooperation between the oil tank fixing frame 51 and the seismic frame 4, the remaining seismic energy is further offset, thereby further improving the stability of the oil tank.

[0036] In this embodiment, please refer specifically to Figures 7-8. The seismic isolation base 6 includes a seismic isolation raised seat 61. The bottom surface of the seismic isolation raised seat 61 is located at the center of the top surface of the main base 7. The top surface of the seismic isolation raised seat 61 is provided with multiple lead-core rubber seismic isolation supports 62. The top surfaces of the multiple lead-core rubber seismic isolation supports 62 are all located on the bottom surface of the seismic isolation movable seat surface 63. The seismic-resistant frame 4 is provided on the top surface of the seismic isolation movable seat surface 63. The seismic isolation frame 4 is located around the bottom surface of the seismic isolation movable seat surface 63. Each is equipped with a water-retaining side enclosure 631. The height of the water-retaining side enclosure 631 above the ground is less than or equal to half the height of the seismic isolation raised seat 61. This design isolates a large amount of seismic energy through the deformation of multiple lead-core rubber seismic isolation bearings 62, with only a small portion of the seismic energy being transmitted to the seismic-resistant frame. The seismic isolation raised seat 61, in conjunction with the water-retaining side enclosure 631, prevents the liquid accumulated in the protective weir 8 from contacting the multiple lead-core rubber seismic isolation bearings 62, thereby extending the service life of the multiple lead-core rubber seismic isolation bearings 62.

[0037] In this embodiment, please refer to Figures 9-10. The top surface of the main base 7 is provided with multiple anti-collision pillar units 71. Each anti-collision pillar unit 71 includes a pillar core 711. A replaceable energy-absorbing rubber sleeve 712 is fitted on the outer side of the middle part of the pillar core 711. This design uses multiple anti-collision pillar units 71 to prevent the vehicle from directly colliding with the storage tank, thus avoiding a serious explosion accident. The replaceable energy-absorbing rubber sleeve 712 further absorbs the energy during the collision and is easy to replace, avoiding the need to replace the pillar core 711 and reducing repair costs.

[0038] In this embodiment, please refer to Figure 11 for details. The protective weir 8 has a step 81 on its outer side and a standing platform 82 on its inner side, which is located corresponding to the position of the fuel dispenser 1, so that users can approach the fuel dispenser 1 to carry out refueling operations.

[0039] Operating principle: When an earthquake occurs, a large amount of seismic energy is first isolated by the deformation of multiple lead-core rubber seismic isolation bearings 62, with only a small portion of the seismic energy being transmitted to the seismic-resistant frame 4. The seismic isolation riser 61, in conjunction with the water-retaining sidewall 631, prevents the accumulated liquid in the protective weir 8 from contacting the multiple lead-core rubber seismic isolation bearings 62, thereby extending the service life of the multiple lead-core rubber seismic isolation bearings 62. The seismic-resistant frame 4 absorbs the seismic energy received by the frame body 41 through the viscous damper 431, reducing the swaying of the frame body 41 and preventing a small amount of seismic energy from directly impacting the frame. The energy could be transferred to the oil storage tank or other equipment, potentially causing an explosion. Multiple seismic support units 53, through multiple support energy dissipation dampers and auxiliary support rods 534, form a support structure. Combined with the sliding cooperation between the oil tank fixing frame 51 and the seismic frame 4, the remaining seismic energy is further offset, thereby further improving the stability of the oil tank. Multiple anti-collision column units 71 prevent the vehicle from directly impacting the storage tank, thus avoiding a more serious explosion accident. Replaceable energy-absorbing rubber sleeves 712 further absorb the energy during the collision, and are easy to replace, avoiding the need to replace the column core 711.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
