For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] The present embodiment relates to a FRP storage tank with a double-layer lining, in order to improve the impact resistance of the FRP storage tank and improve the safety of the FRP storage tank.

[0028] In terms of overall structure, Figure 1 to Figure 2 As shown, the glass fiber reinforced plastic storage tank with double-layer lining includes an outer shell 1, an inner liner layer 2 and an energy absorbing member 3. The inner liner layer 2 is located in the outer shell 1, and the outer shell 1 and the inner liner layer 2 form a buffer cavity 4. A plurality of energy absorbing members 3 are provided, and the plurality of energy absorbing members 3 are all located in the buffer cavity 4. The energy absorbing member 3 is configured such that when the outer shell 1 is locally impacted, the energy absorbing member 3 provided at the impacted location absorbs the impact force generated by the impact.

[0029] By providing an inner liner layer 2 and an energy absorbing member 3 in a buffer cavity 4 formed by the inner liner layer 2 and the outer shell 1, the sealing and safety of the FRP storage tank are improved when the outer shell 1 is impacted from the outside. When the outer shell 1 is partially impacted, the energy absorbing member 3 is provided to absorb the impact force generated by the impact, thereby reducing the impact on the inner liner layer 2 and improving the safety of the FRP storage tank.

[0030] Based on the above overall introduction, the energy absorbing member 3 in this embodiment is as follows Figures 2 to 3 As shown, the energy absorbing member 3 includes a conducting part 31 and an energy absorbing part 32. The conducting part 31 transmits the impact of the outer shell 1 to the inner liner layer 2; the energy absorbing part 32 is connected to the conducting part 31, and the energy absorbing part 32 is configured to absorb or transmit the impact energy of the outer shell 1 to the inner liner layer 2 when the conducting part 31 impacts. Specifically, whether the energy absorbing part 32 transmits the energy of the outer shell 1 to the inner liner layer 2 when the conducting part 31 impacts the inner liner layer 2 depends on the relationship between the maximum energy that the energy absorbing part 32 can absorb and the energy transmitted to the energy absorbing part 32 when the impact force of the outer shell 1 causes the outer shell 1 to deform and transmit to the energy absorbing part 32. When the energy transmitted to the energy absorbing part 32 is greater than the maximum limit that the energy absorbing part 32 can absorb and carry, the energy is partially absorbed by the energy absorbing part 32, and the remaining part is transmitted to the inner liner layer 2. When the energy transmitted to the energy absorbing part 32 is less than the maximum limit that the energy absorbing part 32 can absorb and carry, the energy is absorbed by the energy absorbing part 32.

[0031] like Figures 2 to 3 As shown, in a specific implementation, in order to increase the energy absorption area that the energy absorption part 32 can cover, the number of energy absorption parts 32 is reduced, and the production of glass fiber reinforced plastic storage tanks is facilitated. The conduction part 31 includes a conduction rod 311 and a guide plate 312. The conduction rod 311 is oriented toward the center line of the length direction of the outer shell 1 and is perpendicular to it. When the outer shell 1 is impacted, the conduction rod 311 transmits the impact energy in the direction toward the center line of the length direction of the outer shell 1. The guide plate 312 is vertically fixedly connected to one end of the conduction rod 311 close to the outer shell 1, and the guide plate 312 is used to increase the range of the conduction rod 311 that can transmit the impact force.

[0032] The energy absorbing part 32 includes a limiting cylinder 321, an elastic member 322 and a pad 323. The limiting cylinder 321 corresponds to the conduction rod 311 included in the same energy absorbing member 3; the elastic member 322 is located in the limiting cylinder 321, and is constructed so that the elastic member 322 produces elastic deformation when subjected to pressure; the pad 323 is located in the limiting cylinder 321, and the pad 323 is fixedly connected to the conduction rod 311. When the conduction rod 311 is impacted, the pad 323 evenly transfers the impact force to the elastic member 322.

[0033] As a preferred embodiment, one end of the conducting rod 311 is plugged into the side of the limiting cylinder 321 away from the inner liner layer 2, and the end of the conducting rod 311 is vertically fixedly connected to the pad 323; the end of the pad 323 away from the conducting rod 311 is always in contact with the elastic member 322, and pushes the elastic member 322 to move in the limiting cylinder 321. Thus, the impact force of the conducting rod 311 toward the length reverse center line of the outer shell 1 is absorbed or transmitted.

[0034] As a preferred implementation, in this embodiment, a spring can be used as the elastic member 322. Of course, using a spring as the elastic member 322 is only a preferred implementation. In addition, the elastic member 322 can also be other objects with a buffering function commonly used in the prior art, such as elastic gaskets or rubber products. When a rubber product is used as the elastic member 322, there is a space between the limiting cylinder 321 and the elastic member 322 to facilitate the deformation of the elastic member 322.

[0035] In addition, as a better setting method, Figures 2 to 3 As shown, the glass fiber reinforced plastic storage tank with double-layer lining of this embodiment further includes a strengthening layer 5 and a buffer insulation layer 6, the strengthening layer 5 is laid outside the inner liner layer 2, and the energy absorbing member 3 is connected to the strengthening layer 5. In the specific setting, the above-mentioned limiting cylinder 321 is fixedly connected to the strengthening layer 5, and the extension line of the length direction center line of the limiting cylinder 321 is perpendicular to and intersects with the length direction center line of the outer shell 1. The strengthening layer 5 can be made of glass fiber reinforced plastic as raw material.

[0036] The buffer insulation layer 6 is attached to the inner wall of the outer shell 1, and the energy absorbing member 3 is connected to the buffer insulation layer 6. In specific implementation, the guide plate 312 is fixedly connected to the side of the buffer insulation layer 6 away from the outer shell 1, and the connection method can be bonding.

[0037] The provision of the strengthening layer 5 improves the strength of the inner liner layer 2, thereby improving the impact resistance of the inner liner layer 2 and improving the sealing of the inner liner layer 2. When the energy absorbing member 3 cannot completely absorb the impact energy caused by external impact, the provision of the strengthening layer 5 also improves the impact resistance of the inner liner layer 2, thereby improving the safety of the FRP storage tank. The provision of the buffer insulation layer 6 improves the thermal insulation performance of the FRP storage tank, and the buffer insulation layer 6 can reduce the impact force transmitted from the outer shell 1 to the conduction part 31 to a certain extent. Ultimately, the impact force on the inner liner layer 2 is reduced, and the safety and stability of the FRP storage tank are improved.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
