When the manned submersible is observed or sails under the deep and large diving environment, the anti-collision protection device is arranged outside the observation window 1, so that a hard object cannot directly collide with the observation window 1, if the lower glass sealing cover 6 is collided by the hard object, the lower glass sealing cover 6 is in a normal stress state, so that a certain collision force can be borne without damage, the collision force is dispersed into the bottom layer pressure balancing liquid bag 7 through liquid in the bottom layer cavity 100, the collision force is dispersed, the stress transmitted to the observation window 1 is very small, and the uniform distribution acts on the observation window, and the safety of the observation window is protected. Simultaneously this kind of structure has avoided setting up of outstanding style observation window protective frame or has set up the observation window in structural frame, and when normal use state, can directly observe glass closing cap 6 is close observed object down, effectively increases observation effect.
The above description discloses a single-layer protection structure of the collision protection device of the present application, but the collision protection device of the present application is more commonly a double-layer protection structure in practical application, please refer to fig. 2-4, and the collision protection device further includes an upper cavity structure 10, an upper glass cover 11, an upper pressure balancing liquid bag 12, an upper pressure balancing pipe 13 and a slotted buffer bracket 14. The bottom setting of upper cavity structure 10 is at bottom cavity structure 5's top, and the upper cavity structure 10 that this application provided and bottom cavity structure 5's connected mode does: bottom cavity structures 5's top still includes to the outside convex upper flange of cavity, lower glass closing cap 6 sets up the upper surface at bottom cavity structures 5's upper flange and fixes through the mounting, upper cavity structures 10's bottom includes to the inside convex bottom flange of cavity, upper cavity structures 10's bottom flange nestification is at the lower surface of bottom cavity structures 5's upper flange, upper glass closing cap 11 sets up at upper cavity structures 10's top opening part and fixes through the mounting, seal through setting up sealing member 15 in upper cavity structures 10's top opening part's hoop inslot between upper glass closing cap 11 and upper cavity structures 10. The upper cavity structure 10 is also connected with the connecting flange 4 through the slotted buffer support 14, as shown in the figure, the lower surface of the bottom flange of the upper cavity structure 10 is connected with the connecting flange 4 through the slotted buffer support 14, and the slotted buffer support 14 is uniformly arranged in a plurality along the circumferential direction of the connecting flange 4. An upper cavity 200 is formed among the upper cavity structure 10, the lower glass sealing cover 6 and the upper glass sealing cover 11, an upper pressure balance liquid bag 12 is arranged on the pressure-resistant structure 2 of the manned submersible, and the upper pressure balance liquid bag 12 is communicated with the upper cavity 200 through an upper pressure balance pipe 13. Similarly, before the manned submersible vehicle submerges, pure transparent liquid is injected into the upper pressure balance liquid bag 12, the upper pressure balance tube 13 and the upper cavity 200 and air is squeezed out, so that the communication structure formed by the upper pressure balance liquid bag 12, the upper pressure balance tube 13 and the upper cavity 200 is filled with pure transparent liquid and is free of air.
When the manned submersible equipped with the anti-collision protection device with the double-layer structure shown in fig. 2-4 is in a large deep diving environment and in a normal use state, the bottom layer pressure balancing liquid bag 7 and the upper layer pressure balancing liquid bag 12 are both deformed under the action of the external seawater pressure, the bottom layer pressure balancing liquid bag 7 extrudes the internal liquid into the bottom layer cavity 100 through the bottom layer pressure balancing pipe 8, and the upper layer pressure balancing liquid bag 12 extrudes the internal liquid into the upper layer cavity 200 through the upper layer pressure balancing pipe 13. Meanwhile, the upper glass sealing cover 11 is used as the outermost glass sealing cover to be directly contacted with the external seawater and subjected to the pressure of the external seawater, and then the pressure is transmitted to the upper cavity 200 and the lower glass sealing cover 6, and finally the pressure is balanced with the pressure transmitted by the pressure balancing liquid bag, so that the structural stability of the invention in a large submergence depth environment is maintained, and the lower glass sealing cover 6 and the upper glass sealing cover 11 are both in an undeformed normal stress state.
When the manned submersible is used for observing or navigating in a deep and large diving environment, if the upper glass sealing cover 11 is collided by a hard object, the upper glass sealing cover 11 is in a normal stress state, so that the manned submersible can bear a certain collision force without being damaged, the collision force is sequentially dispersed and transmitted to the upper pressure balance liquid bag 12 and the lower glass sealing cover 6 and the bottom pressure balance liquid bag 7 through liquid in the upper layer cavity 200, the collision force is dispersed, the stress transmitted to the observation window 1 is very small, and the stress is uniformly distributed and acts on the observation window 1, so that the safety of the observation window 1 is protected. Similar with single-layer protective structure, double-deck protective structure can directly be observed the observed object of going up glass closing cap 11 and being close when normal use state, effectively increases observation effect. Moreover, when the double-layer structure is adopted, if the upper glass cover 11 is crashed by a hard object, a part of stress is absorbed, and the transmission of the impact force to the lower glass cover 6 is prevented or weakened, and the lower glass cover 6 and the bottom layer pressure balancing liquid bag 7 still keep a pressure balancing state, namely, a single-layer protection structure is formed as described above, so that the safety of the observation window 1 can be continuously protected, and the use of the observation window 1 is not influenced.
When the manned submersible is used for observation or navigation in a deep diving environment, a hard object may collide with the glass cover 11 or the edge of the glass cover 11, and transmits force to the upper cavity structure 10, at the moment, the collision force is respectively transmitted to the bottom cavity structure 5 and the slotted buffer bracket 14 through the upper cavity structure 10 and a fixing piece between the upper glass cover 11 and the upper cavity structure 10, and the buffer collision force is damaged through the deformation of the bottom cavity structure 5 and the bending of the slotted buffer bracket 14 at the slot, so that the acting force on the connecting flange 4 and the observation window cabin penetrating piece 3 is weakened, and therefore, the double-layer protection structure of the figures 2-4 can not only protect the safety of the observation window 1, but also protect the safety of the observation window cabin penetrating piece 3.
It should be noted that, in practical application, even a three-layer or four-layer structure may be adopted, the structure and the protection principle of the structure are similar to those of the above-mentioned two-layer protection structure, and those skilled in the art may expand the structure based on fig. 2 to 4, which is not limited in the present application. In the use process of the anti-collision protection device, due to collision, a sealing structure and a pressure balance state can be damaged, the bottom layer cavity 100 and the upper layer cavity 200 can enter seawater, but the damage only affects the observation effect, the observation window 1 and the observation window cabin penetrating piece 3 are not damaged, and the safety of the observation window 1 and the observation window cabin penetrating piece 3 is effectively protected.
What has been described above is only a preferred embodiment of the present application, and the present invention is not limited to the above embodiment. It is to be understood that other modifications and variations directly derivable or suggested by those skilled in the art without departing from the spirit and concept of the present invention are to be considered as included within the scope of the present invention.
