Description
Technical field
The present invention relates to a kind of anti-impact protective device, relate in particular to a kind of Unpowered self-separating type anti-impact protective device, belong to the seafari equipment technical field.
Background technology
At present; when throwing in off-lying sea input detecting devices to the ocean by the high-altitude; what mostly adopt is that the impulsive force of the suffered water surface is protected equipment when using descending speed that parachute slows down object and reducing the equipment entry; because the restriction of all many-sided factors such as angle the when resistance that reduces of parachute is subject to the height of parachute-opening and entry; and the price of parachute is comparatively expensive; the arming mechanism of umbrella and equipment room is complicated; thereby it is too high to be used for the required funds of high-altitude delivery equipment; reliability in actual use neither be too high, throws in detecting devices so be not suitable for being applied to the off-lying sea high-altitude.
Summary of the invention
The invention provides a kind of Unpowered self-separating type anti-impact protective device, the impulsive force that is subject in the time of can effectively cushioning the detecting devices entry makes detecting devices and fender guard reliable separation simultaneously.
A kind of Unpowered self-separating type anti-impact protective device, a kind of Unpowered self-separating type anti-impact protective device, comprise upper shell, probe, non-metallic layer, lower house, connecting rod, clamping device, support, weight block, upper guide ring, lower guide ring, spring, wherein, clamping device comprises fixedly nipper, movable nipper and cam link, and the material of non-metallic layer can be made by natural rubber or other antidetonation non-metals; Upper shell and lower house are the three-clove style structure, combine and consist of the cylindrical cavity structure, the through hole that one installation probe is axially all arranged of every lobe upper shell, one section shifting chute that plays position-limiting action is all arranged on each through hole, on every lobe lower house also to the through hole that probe is installed should be arranged, non-metallic layer also is the three-clove style structure, and profile is corresponding with shape all-in-one-piece upper shell and lower house; The center of weight block bottom surface processes conglobate Baltimore groove, and the one, play the effect of fixing spring; The 2nd, when being subject to foreign impacts for support, leave enough displacement spaces; Stressed during for the entry of assurance support evenly the bottom surface of support is arc-shaped structure, and there is vertical center link at the center, pin joint cam link and connecting rod on the center link.Its annexation is: the upper cavity that detecting devices places non-metallic layer to consist of is inner, the lower cavity that weight block places non-metallic layer to consist of is inner, upper guide ring and lower guide ring are installed in up and down in the Baltimore groove of weight block, spring is free state and is installed between guide ring and the lower guide ring, and the upper end of the center link of support is inserted in spring and is captiveed joint with the spring lower end; Probe after running through the through hole of upper shell and lower house connects as one upper shell and lower house, the fabricate block of three lobe upper shells and lower house is coated on the non-metallic layer cylindrical, clamping device constitutes one by the standard connecting pin with it by fixedly nipper, movable nipper and cam link, and the fixedly nipper on the clamping device and movable nipper can be clamped in it on outside face of lower house by cam link; Clamping device is circumferentially fixing with the bottom surface of lower house under the effect of spring and support, and probe is captiveed joint with support by connecting rod at the shifting chute place of upper shell.
For the anti-impact protective device of guaranteeing to assemble after finishing can consist of whole by failure-free, flare structure after connecting rod assembling finished, be the circumferential diameter in connecting rod and support point of connection position greater than the circumferential diameter in connecting rod and probe point of connection position, can guarantee that like this assembling finishes rear linking rod and can radially provide a thrust to upper shell; For guaranteeing in transportation, fender guard can not be provided with a pin in the junction of probe and upper shell because being given a shock or other reasons separates, and frees pin before input.
Working process: when underwater detection equipment drops into the water from the high-altitude with this device; when the device entry; support is subject to the water surface to its impulsive force; this moment, the support against the force of the spring was mobile straight up with respect to weight block; move on the drivening rod simultaneously, so that the end of probe separates with lower house, free being connected between upper shell and lower house; fender guard is decomposed, finish separating of detecting devices and this device.The function of spring in whole device mainly contains: the one, and when support was subject to impulsive force and is subjected to displacement, spring was compressed and sponge the part impact energy, plays the first-level buffer effect; The 2nd, guarantee that fixing and holding mechanism can reliable clamping lower house.When guaranteeing air-drop because the impact of wind-force; when making the protective device entry and the water surface one angle is arranged; namely not to be the vertical angle entry; also be provided with non-metallic layer at protective device housing and protected equipment room; consist of the second class protection layer; the deflection that utilizes non-metallic layer 3 to produce when being subject to impacting sponges the part of impact force of remainder again, plays buffer action.For guaranteeing upper shell and lower casing physical efficiency reliable separation, make cam link in the course of the work, be still can compression activity nipper after cam link rotates to an angle, so that clamping device still can be clamped on the lower house reliably, drivening rod moves to drive probe and is moved when guaranteeing that support is subject to foreign impacts and produces displacement, and upper shell is separated smoothly with lower house; When upper shell with after lower house separates, support still drives the cam link rotation, when rotating to certain angle, cam link reduces gradually to the thrust of movable nipper, clamping device will reduce the Clamping force of lower house this moment, clamping device separates with lower house, is the three-clove style structure without circumferentially fixing lower house owing to its structure like this, also realizes separating with device; When lower house with after detecting devices separates, non-metallic layer, support, weight block and spring also separate with detecting devices without any constraint; Be subject in the impact process of water at support, spring utilizes its compressive deformation to cushion the impact of water to detecting devices, and non-metallic layer also uses the mode buffered water of structural distortion to the impact of detecting devices around detecting devices.
Beneficial effect: the present invention can adjust the entry angle automatically in dropping process, thereby has avoided the entry angle that larger deflection occurs; Because the impulsive force that brings when adopting the two-stage shock absorber to sponge entry greatly, water-entry impulsive force in safe range, has increased the safety factor of equipment on the impact of equipment, has reduced the impact of impulsive force on equipment, have higher reliability and feasibility, and greatly reduced cost.
