Specific implementation manner
[0026] The purpose of the present invention is to provide a motorized multi-stage protection structure oil depot in view of the deficiencies of the prior art, which is specifically realized by the following technical solutions: In the present invention: STF refers to shear thickening fluid; Kevlar refers to Kevlar fabric; CNT refers to carbon nanotube material; flame-retardant modified PU refers to polyurethane; SPUA refers to elastomeric spray material polyurea; FKM refers to fluororubber; DCPD refers to cyclopentadiene; TPU refers to thermoplastic polyurethane elastomer.
[0027] Refer to Figures 1-5, this embodiment provides a motorized multi-level protection structure oil depot, including: a multi-level protection structure oil depot, and an oil depot locking structure 6 arranged on a fixed base. It is characterized in that the fixed base is arranged at the fixed location where the multi-level protection structure oil depot needs to be installed and on the transport vehicle for transporting the multi-level protection structure oil depot. The multi-level protection structure oil depot is locked by the oil depot locking structure 6 arranged on the fixed base, and the function of disassembling and assembling the multi-level protection structure oil depot from the fixed base can be realized through the locking structure 6. An oil inlet hole 45 and a ventilation hole 46 are arranged at the top of the multi-level protection structure oil depot. The outer shell of the multi-level protection structure oil depot is a three-layer structure, with its outer layer being a hard medium high-strength steel plate 1, the inner layer being a tough medium STF-impregnated Kevlar fabric 3, and a cavity fire-retardant and explosion-suppressing layer 2 being filled between the outer layer and the inner layer. The cavity fire-retardant and explosion-suppressing layer 2 is composed of a fire-retardant modified PU foam 22 embedded in a CNT cavity 21 as a structure body. The mass fraction of SiO2 in the STF-impregnated Kevlar fabric 3 is 34%. An internal component compartment self-sealing structure is arranged in the multi-level protection structure oil depot, and an oil channel 47 is arranged in the compartment to ensure the connection of each compartment. The compartment self-sealing structure uses a self-sealing material 4 plate, and explosion-suppressing balls 5 are added to the compartment.
[0028] The self-sealing material is composed of SPUA41, FKM42 added with an oil-absorbing resin, a steel plate 43, and TPU44 containing a DCPD repair agent. The sealing material is composed of spraying SPUA41 on the front of FKM42 added with an oil-absorbing resin through a composite material spraying process and sequentially laying a steel plate and TPU44 containing a DCPD repair agent on its back. The interior of the oil depot presents a honeycomb structure, and an oil channel is arranged in the structure to ensure the connection of each compartment.
[0029] Under the impact of the projectile, the outer medium high-strength steel plate 1 induces the fragmentation of the projectile and reduces the impact velocity of the projectile. The CNT cavity filled with flame-retardant modified PU foam cavity flame-retardant and explosion-suppression layer 2 dissipates the impact energy through shock absorption, making the impact energy discrete and further reducing the fragment velocity. The inner medium STF-impregnated Kevlar fabric 3 induces the deformation retardation of the fragments to achieve the goal of ensuring the integrity of the oil depot. After the remaining projectile fragments enter the compartment self-sealing structure, the elastomer spraying material - SPUA 41 in the self-sealing material 4 plate further consumes the kinetic energy of the fragments through elastic deformation. The oil-soluble swelling material - FKM 42 added with oil-absorbing resin rapidly swells under the excitation of oil spillage to block the perforated part. The steel plate 43 supports the internal structure and reduces the structural deformation. The TPU 44 containing DCPD repair agent flows out the DCPD repair agent after perforation to effectively self-repair the perforated part. The perforated part is gradually closed under the multi-mechanism synergistic inhibition of the compartment self-sealing material, blocking oxygen, reducing the oil-gas mixture and avoiding secondary explosion at the contact interface. The internal of the multi-stage protection structure oil depot is set as a compartment self-sealing structure, which divides the inside of the oil depot into many small spaces, and ensures the connectivity of the oil between each compartment and the normal use of the oil depot through the oil inlet 45, ventilation hole 46, oil channel 47 and oil outlet 48, further reducing the impact damage of the projectile fragments on the inside of the oil depot. And the explosion suppression balls 5 are added in the structure, which can instantaneously cut off the propagation path of the shock wave and absorb the shock wave energy to ensure that the combustible gas in the oil depot cannot explode.
[0030] The protection principle of this technology is as follows: Using high-strength steel plate as a hard medium, the projectile is induced to break during the impact process, and the impact velocity of the projectile is reduced. The fragments enter the CNT cavity filled with flame-retardant modified PU foam cavity flame-retardant and explosion-suppression layer. This structure undergoes reversible elastic deformation when impacted by the fragments, and absorbs part of the kinetic energy generated by the fragments through vibration, thus achieving the effect of slowing down the impact force of the fragments. The remaining fragment kinetic energy passing through the CNT cavity filled with flame-retardant modified PU foam cavity flame-retardant and explosion-suppression layer is greatly weakened and is wrapped by the tough material STF-impregnated Kevlar fabric, further reducing the damage of the projectile fragments to the oil depot and achieving the goal of the integrity of the oil depot. The shock wave generated by the projectile impact enters the interior of the oil depot. The explosion-suppression ball instantaneously cuts off the propagation path of the shock wave and absorbs the shock wave energy to ensure that the combustible gas in the oil depot cannot explode. For the fragments entering the interior of the oil depot, SPUA absorbs the impact energy again through elastic deformation, reducing the damage of the projectile fragments to the interior of the oil depot. The FKM with oil-absorbing resin added after the perforation of the compartment self-sealing structure expands rapidly under the excitation of oil spillage to block the perforation site. After the perforation of the TPU containing DCPD repair agent, the DCPD repair agent flows out to effectively self-repair the perforation site. The perforation site is continuously inhibited by multiple mechanisms of the compartment self-sealing material until it is completely closed. The compartment self-sealing structure divides the internal space into a large number of small spaces. There are oil channels in the structure to ensure the connection of each compartment, block oxygen, and further reduce the impact damage of the projectile fragments to the interior of the oil depot.
[0031] Refer to Figures 6-8 , a protruding buckle is provided at the bottom of the multi-level protection structure oil depot, and a groove matching it is provided on the supporting fixed base, which is convenient for the oil depot to be placed on the fixed base. Just align the buckle with the groove directly to complete the placement work. There is a cavity structure inside the supporting fixed base, and the oil depot locking structure 6 is arranged in the cavity, which can realize the locking of the oil depot and the fixed base, so that even when there are bumps, sharp turns, etc. during the transportation process, the oil depot will not break away from the fixed base.
[0032] Refer to Figure 6, the oil depot locking structure 6 includes: a driving link 61, a front rocker arm 62 is provided at the front end of the driving link 61. A front central rotating shaft 621 is provided at the center of the front rocker arm 62. The front rocker arm 62 is fixedly connected to the inside of the fixed base through the front central rotating shaft 621. The front rocker arm 62 extends in two directions from the front central rotating shaft 621 to form a first front rocker arm 622 and a second front rocker arm 623. The first front rocker arm 622 is connected to the front end of the driving link 61 through a pin shaft. A first front connecting rod 63 and a third front rocker arm 64 are further provided at the front end of the front rocker arm 62. One end of the first front connecting rod 63 is connected to one end of the third front rocker arm 64 through a pin shaft, and the other end is connected to the second front rocker arm 623 through a pin shaft. The other end of the third front rocker arm 64 is fixedly connected to the inside of the fixed base through a rotating shaft. One end of a second front connecting rod 65 is also connected to the pin shaft between the first front connecting rod 63 and the third front rocker arm 64. The other end of the second front connecting rod 65 is connected to one end of a front locking hook 66 through a pin shaft. The other end of the front locking hook 66 is fixedly connected to the inside of the fixed base through a rotating shaft. A rear rocker arm 67 is provided at the rear end of the driving link 61. A rear central rotating shaft 671 is provided at the center of the rear rocker arm 67. The rear rocker arm 67 is fixedly connected to the inside of the fixed base through the rear central rotating shaft 671. The rear rocker arm 67 extends in two directions from the rear central rotating shaft 671 to form a first rear rocker arm 672 and a second rear rocker arm 673. The first rear rocker arm 672 is connected to the rear end of the driving link 61 through a pin shaft. A first rear connecting rod 68 and a third rear rocker arm 69 are further provided at the rear end of the rear rocker arm 67. One end of the first rear connecting rod 68 is connected to one end of the third rear rocker arm 69 through a pin shaft, and the other end is connected to the second rear rocker arm 673 through a pin shaft. The other end of the third rear rocker arm 69 is fixedly connected to the inside of the fixed base through a rotating shaft. One end of a second rear connecting rod 70 is also connected to the pin shaft between the first rear connecting rod 68 and the third rear rocker arm 69. The other end of the second rear connecting rod 70 is connected to a rear locking hook 71 through a pin shaft. The other end of the rear locking hook 71 is fixedly connected to the inside of the fixed base through a rotating shaft.
[0033] The working principle is as follows: When the driving link 61 moves forward, it will drive the first front rocker arm 622 connected to it to rotate forward, and then drive the front rocker arm 62 rotating around the front central rotating shaft 621 to rotate forward. The forward rotation of the front rocker arm 62 causes the second front rocker arm 623 to rotate forward, driving one end of the first front connecting rod 63 connected to it to move. The other end of the first front connecting rod 63 is connected to the third front rocker arm 64 and rotates around the rotating shaft where the third front rocker arm 64 is fixedly connected to the fixed base. In this way, the front end of the first front connecting rod 63 moves forward around the rotating shaft of the third front rocker arm 64, and then pushes the rear end of the second front connecting rod 65 connected to it through a pin shaft to move forward. The front end of the second front connecting rod 65 is connected to one end of the front locking hook 66 through a pin shaft. The other end of the front locking hook 66 is fixedly connected to the fixed base through a rotating shaft. The front locking hook 66 can only rotate in a circular motion around the rotating shaft. The front end of the second front connecting rod 65 pushes the front locking hook 66 forward, causing it to hook the oil depot lock catch and complete the locking work.
[0034] Similarly, when the driving link 61 moves forward, it will drive the rear rocker arm 67 to rotate forward, and then drive the end of the first rear link 68 connected to the rear rocker arm 67 to move forward. The other end of the first rear link 68 rotates around the rotating shaft where the third rear rocker arm 69 is fixedly connected to the fixed base as the axis, thereby driving one end of the second rear link 70 connected thereto to move forward. The other end of the second rear link 70 is pin-connected to one end of the rear locking hook 71, and the other end of the rear locking hook 71 is fixedly connected to the fixed base through a rotating shaft. The second rear link 70 pushes the rear locking hook 71 to move backward, so that it hooks the oil depot lock catch and completes the locking work.
[0035] For unlocking, only by moving the driving link 61 backward can the unlocking work be completed. Thus, the locking structure 6 can achieve rapid locking and unlocking functions, and further meet the requirements of motorized transportation and fixed-site installation of the multi-level protection structure oil depot. On the transport vehicle for transporting the multi-level protection structure oil depot, the locking structure 6 can limit the oil depot on the vehicle and prevent large displacements, ensuring the stability of the oil depot during transportation. Moreover, the locking structure 6 can achieve rapid locking and unlocking functions, thus further shortening the disassembly and assembly time of the oil depot and enabling it to meet the requirements of faster motorized transportation.
[0036] Refer to Figure 8 , two sets of oil depot locking structures 6 are provided. The two sets of oil depot locking structures 6 are connected by a connecting frame to connect the two driving links 61, enabling them to move synchronously. The two sets of locking mechanisms can make the oil depot more stably restricted on the fixed base. When it is transported, the same fixed base is provided on the transport vehicle such as a vehicle for transporting the oil depot, which can lock the oil depot and further ensure the safety of the oil depot during transportation.
[0037] Refer to Figure 8 , a driving rod 72 is provided on the side of the driving link 61 close to the outside of the fixed base. A corresponding opening is provided on the fixed base, so that the driving rod 72 protrudes laterally from the fixed base. A locking hole 73 is also provided on the driving link 61. When the driving link 61 moves to the frontmost position, an opening is also provided on the fixed base at the position corresponding to the locking hole 73, and a lock shaft can be used to lock the oil depot locking structure 6. The driving rod 72 can be used to manually drive the entire locking device. Since the overall structure is designed with a pure mechanical structure and uses link operation, the required driving force is very small and can be completed by manpower. The significance of the locking hole 73 is that when the driving link 61 of the oil depot locking structure 6 is pushed to the locking position, a lock shaft is inserted from the outside of the fixed base, which can pass through the fixed base and the driving link 61, so that the entire oil depot locking structure 6 is fixed by the lock shaft and cannot move again. Only by pulling out the lock shaft can the unlocking operation be performed.
