As shown in fig. 1 to fig. 2, according to the utility model provides a high altitude income water autosegregation device, include: the protective cover 1 and the force-bearing separation component 2; the stress separation component 2 is arranged on the protective cover 1; the force-receiving separator assembly 2 includes: separating the half ring 21 and the fixing ring 22; the separating half ring 21 is connected with the fixing ring 22 through steel balls. In a preferred embodiment, after the device is installed on a high-altitude water-entering product, when the device enters water, the piston axially moves under the action of impact force to overcome the resistance of the spring, after a certain distance is reached, the steel balls lose position limitation, and the protective covers automatically separate under the condition that the protective covers lose the restriction on the left and right of the impact force. In a preferred embodiment, the protective cover has an inner shape conforming to the product to be protected and an outer shape conforming to the diameter of the launch canister. The two protective covers are respectively fixed with mounting flange screws on the stress separation assembly. The stressed separating component comprises a fixing ring, a separating semi-ring, a piston, a spring, a steel ball, a screw and the like. The lower part of the fixing ring is in a complete column shape, and the upper flange is a semi-annular flange. The lower part of the separating semi-ring is of a semi-annular structure, the diameter of the inner side of the semi-ring is consistent with that of the lower part of the fixing ring, and the flange on the upper part of the separating semi-ring is also a semi-annular flange. Two small holes are symmetrically formed in the annular structure at the lower part of the separating semi-ring at an angle of 180 degrees in the radial direction, and when the separating semi-ring is assembled with the fixing ring, the small holes in the separating semi-ring are coaxial with the ball mounting holes in the fixing ring.

Further, a positioning pin 11 is arranged on the protective cover 1; the separator half ring 21 is provided with a small hole 28; the fixed ring 22 is provided with a piston 23; the piston 23 is provided with a groove 27; the piston 23 is mounted on the fixed ring 22 by means of screws 25. In a preferred embodiment, the steel balls are placed in holes on the circumference of the retaining ring, the spring is placed in a retaining position of the retaining ring, the piston is mounted in the retaining ring and is connected with the piston through the retaining ring by screws for limiting the axial movement range of the piston. When the upper surface of the piston is level with the upper surface of the fixed ring, the spring has certain precompression force, and the precompression force can be used for resisting wind resistance when falling at high altitude. The side surface of the piston is provided with a groove, and when the piston does not move under stress, the steel ball cannot roll into the groove of the piston. The steel ball protrudes out of the outer surface of the fixing ring. When the piston is forced to move for a certain distance, the steel balls can roll down into the groove of the piston, and the steel balls do not protrude out of the outer surface. In a preferred embodiment, when the automatic water inlet separating device is directly arranged at the head of a protected product, the product and the protecting device only need to be axially limited because the interior of the protecting cover is conformal with the head of the protected product, the assembled automatic separating device cannot be separated from the product, and the automatic separating device can be separated from the protected product along the radial direction after being separated. When the protected product enters water from high altitude, the piston overcomes the pre-pressure of the spring under the influence of impact force, so that the piston moves axially, after moving for a certain distance, the steel balls lose the radial movement limitation of the piston and can roll into the groove on the piston, the separating semi-ring can be separated from the fixing ring, the two protective covers lose the radial limitation, the protective covers are separated towards the two side surfaces of the protected product under the action of the impact force, and the protected product enters water according to the original track.

The separating semi-ring can not be separated from the fixing ring under the action of the steel balls, so that the two protective covers are connected into a whole. A positioning pin with a spherical head and a positioning hole can be designed on the joint surface of the protective cover, so that the coaxiality is higher when the protective covers are combined together, and the stress of the steel balls can be reduced. In a preferred embodiment, when the automatic water-entering separating device is used for water-entering protection and automatic parachute release, the automatic water-entering separating device is arranged at the head of a protected product, a parachute is arranged at the tail of the protected product, two tying belts on the parachute are respectively connected with two protective covers, when the protected product enters water, a piston overcomes the pre-pressure of a spring under the influence of impact force to enable the piston to axially move, after the steel ball moves for a certain distance, the steel ball loses the radial movement limit of the piston and can roll into a groove on the piston, a separating semi-ring can be separated from a fixing ring, the two protective covers lose the limit and separate, the axial limit is lost on the parachute, the water surface is left under the action of water resistance, and the protected product enters the water according to the.
