Description

Technical Field

[0001] This invention relates to a separation device, belonging to the field of electromechanical technology. Background Technology

[0002] Separation devices are widely used between two connected objects that need to be separated. The two objects can be connected through the device, and separation is achieved under the action of mechanical force, the force of an electromagnetic coil, or the explosive force of an electric detonator. Typically, separation devices are of mechanical, electromagnetic, or electric detonation types; or integrate mechanical and electromagnetic separation, or mechanical and electric detonation separation; while some do not integrate mechanical, electromagnetic, and electric detonation functions, with electric detonation as a backup.

[0003] For example, Chinese patent document CN204110362U discloses an electrically controlled separation mechanism for a drone and its parachute, including a rotating device, an electromagnet, and a locking device. When the locking device is in the locked state, the electromagnet is not energized, the electromagnet armature does not extend, and the driving rod and connecting rod are in a straight line. Utilizing the dead point position of the four-bar linkage, the driven rod subjected to the parachute's pulling force cannot rotate. When the locking device is in the unlocked state, the electromagnet is energized, the electromagnet armature extends, and pushes the driving rod of the four-bar linkage to rotate, thus breaking the dead point position of the four-bar linkage. When the electrically controlled separation mechanism is in the locked state, utilizing the dead point position characteristic of the four-bar linkage, the larger pulling force of the parachute is borne by the driving rod, connecting rod, and driven rod of the four-bar linkage, and the components themselves have high strength and strong load-bearing capacity. When the electrically controlled separation mechanism is unlocked, the armature of the electromagnet outputs a small force to drive the active rod of the four-bar linkage to rotate, thereby breaking the dead position of the four-bar linkage and allowing the sling of the recovered parachute to slide out from the connecting rod. Because the output thrust of the electromagnet is small, the size and weight of the electromagnet and the electrically controlled separation mechanism can be effectively reduced.

[0004] However, when the electromagnet fails, or when the electromagnet cannot push the armature out normally under energized conditions, the electrically controlled separation mechanism will not be able to unlock the locking device. Therefore, the reliability of the separation mechanism needs to be further improved. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides a separation device.

[0006] This invention is achieved through the following technical solution:

[0007] A separation device includes a hanging carrier, a connecting body, and a supporting body. One end of the supporting body is detachably connected to one end of the hanging carrier via the connecting body. The hanging carrier is provided with an electromagnetic separation mechanism and an electric explosion separation mechanism. The electromagnetic separation mechanism is used to control the separation of the hanging carrier from the connecting body, and the electric explosion separation mechanism is used to separate the hanging carrier from the connecting body when the electromagnetic separation mechanism fails.

[0008] The carrier includes a housing, a support sleeve, a separation execution component, an electromagnetic separation mechanism, and an electric explosion separation mechanism.

The separation execution component passes through the base and is slidably connected to the base and bushing. The electromagnetic separation mechanism is located on the base, and the electric explosion separation mechanism is located inside the housing and extends into the support sleeve.

[0009] The separation execution component includes a push rod, on which a moving iron core is fixedly mounted at one end away from the support sleeve, and a circumferential groove with a sealing ring C is provided on the outer circumferential surface of the end of the push rod away from the housing.

[0010] The electromagnetic separation mechanism is an electromagnetic coil, and the electromagnetic coil is mounted on the base.

[0011] The electric explosion separation mechanism includes a sliding sleeve, a switching component, a relay, and an electric explosion tube. The sliding sleeve is located inside the support sleeve and is slidably connected to the support sleeve.

A contact pin is provided axially at one end of the sliding sleeve near the housing. The switching component is located inside the housing, and a contact hole is provided on the switching component at a position corresponding to the contact pin. The electric explosion tube is located inside the housing, and the electric explosion tube push rod part of the electric explosion tube extends directly above the separation execution component. The relay is electrically connected to the contact pin and the switching component.

[0012] The outer circumferential surface of the bushing has a groove and a sealing ring B, the outer circumferential surface of the sliding sleeve has a groove and a sealing ring D, and the bottom of the housing has an annular groove and a sealing ring A.

[0013] The connecting body includes a connecting sleeve, a protective sleeve, a steel ball, and a pull rod. A bushing is fixedly provided inside the connecting sleeve, and part of the bushing extends outside the connecting sleeve. The protective sleeve is located inside the connecting sleeve and is slidably connected to the connecting sleeve, and part of the protective sleeve extends outside the connecting sleeve.

[0017] The beneficial effects of this invention are as follows: it integrates mechanical, electromagnetic and electric explosion separation functions, has high separation reliability, and when the electromagnetic separation is working normally, the electric explosion separation only serves as a backup and does not operate. The electric explosion separation will only operate when the electromagnetic separation fails. Since the electric explosion tube is a consumable and needs to be replaced after one use, the separation device reduces consumables and saves product costs while realizing the backup function of electric explosion separation.

[0034] One end of the carrier is threadedly connected to one end of the connector. One end of the carrier is provided with an external thread, and one end of the connector is provided with an internal thread.

[0035] The working principle of the separation device described in this invention is as follows:

[0036] 1. Achievement of connection and mechanical separation functions: The load-bearing body is used to install and support heavy objects. Connection is achieved by screwing its own threads into the threaded holes of the connecting body. The installation height can be adjusted by changing the screwing length. The connecting body directly connects to the mounting carrier, and the connection state is as follows: Figure 5 As shown, during docking, the carrier component support sleeve 17 pushes the connector component sheath 21 downwards. When it reaches the docking state shown in the figure, the connector component steel ball 19, after losing the support of the connector component sheath 21 and being squeezed by the connector component pull rod 18 (this force comes from the preload of the connector component pull rod spring 23 on the pull rod 18, which will cause the pull rod 18 to be subjected to...), Figure 5 The upward force shown will cause the rod 18 to expand into the groove reserved in the support sleeve 17 of the carrier component; at the same time, after the steel ball 19 is inserted into the annular groove 170 reserved in the support sleeve 17, the rod 18 will lose the resistance of the steel ball 19 and move upward. Figure 5 As shown, the steel ball 19 is held in place within the annular groove 170, thus connecting the carrier and the connector. Mechanical separation is achieved by pressing down on the connector component pull rod 18. The steel ball 19 loses the support of the pull rod 18 and, simultaneously, under the downward force of the carrier and the thrust of the connector component sheath spring 22, the connector returns to its original position. Figure 2 The state is indicated by separation.

[0037] 2. Realization of Electromagnetic Separation Function: When the carrier and the connector are connected, the connecting rod 18 moves upward. This movement pushes the carrier push rod 11 upward. The push rod 11 is fixedly connected to the moving iron core 7 of the carrier. Therefore, during connection, the moving iron core 7 moves upward together with the push rod 11. After the electromagnetic coil 8 of the carrier component is energized, the moving iron core 7 moves downward under the action of electromagnetic force, driving the push rod 11 downward as well. The push rod 11 then pushes the connecting rod 18 downward, thereby achieving electromagnetic separation.

[0038] 3. Realization of delayed electromagnetic separation function: When the carrier and the connector are docked, the bushing 20 of the connector part will push the sliding sleeve 12 of the carrier part upward. The upward movement of the sliding sleeve 12 will insert the contact pin 25 into the socket of the component switching assembly 9, thereby putting the switching assembly 9 in a closed state. After the separation device is energized, the electromagnetic coil 8 will act first to realize the electromagnetic separation function. Simultaneously, the sliding sleeve 12 will move downward under the thrust of the sliding sleeve spring 13 of the carrier component, and the contact pin 25 will disconnect from the socket of the switching component 9, thus making the switching component 9 an open circuit. The relay 2 will become a closed circuit 60ms to 80ms after the electromagnetic coil 8 is energized. The switching component 9 is connected in series with the relay 2 and the electric detonator 5. After the separation device is normally separated, the electric detonator 5 will not detonate because the switching component 9 is disconnected. If the separation device cannot be normally separated 60ms to 80ms after the electromagnetic coil 8 is energized, the switching component 9 will still be in a closed circuit state, and the electric detonator 5 will detonate. After the electric detonator 5 detonates, it will cause the internal electric detonator push rod 6 to move downward, thereby pushing the moving iron core 7 to move downward, driving the push rod 11 to move downward together. The push rod 11 will push the connecting part pull rod 18 to move downward, thereby realizing the delayed electric detonation separation function.
