Description

Technical Field

[0001] The present invention relates to the fields of marine engineering and underwater robot equipment, and in particular to a deep-sea mechanical automatic on-off pressure switch device. Background Art

[0002] Deep-sea scientific research and operational submersibles need to carry a large number of equipment during operation, and will involve a variety of equipment working on the water surface and underwater. In order to ensure the normal power-on and power-off performance of different equipment and to save the submersible's own energy, it is necessary to use underwater switch devices to control the power on and off of the equipment. However, most underwater switch devices in the prior art require the cooperation of staff to operate, and they cannot realize the automatic power on and off function. For example, the Chinese invention patent with authorization publication number CN107578951B discloses a magnetic manual switch that can be used to turn the power on and off of an autonomous underwater robot. When the autonomous underwater robot needs to be powered on on land or in water, the staff needs to put a bar magnet close to the upper cover to control the power on and off. For example, the Chinese invention patent with authorization publication number CN112435883B discloses an underwater mechanical on and off switch. When the underwater robot needs to be powered on, the staff needs to use a flat-blade wrench to turn the switch knob clockwise. For example, the Chinese invention patent with authorization publication number CN111030665B discloses an induction underwater switch. This device uses components such as strong magnets and Hall sensors, and its cost is relatively high. In addition, the device needs to be controlled by turning the handle when in use.

[0024] like Figs. 1-2 As shown, the lower end of the electrical isolation sleeve 12 is provided with an isolation pad 1201, which is abutted against the upper wall of the inner cavity of the upper shell 3 to ensure the electrical isolation effect. The upper end of the electrical isolation sleeve 12 is provided with a accommodating groove 1202, and a firing pin sleeve 14 is provided in the accommodating groove 1202.

[0029] Example 1:

[0030] like Fig. 1 As shown, in this embodiment, the electrical connection assembly includes a non-metallic push rod screw 901, a metal striker column screw 112, a first spring washer 111 and a second spring washer 114, wherein the first spring washer 111 is fixed to the upper end of the inner push rod 8 by the non-metallic push rod screw 901, and the second spring washer 114 is fixed to the lower end of the striker column 13 by the metal striker column screw 112, and the lower end of the self-resetting spring 10 is against the first spring washer 111, and the upper end is against the second spring washer 114.

[0031] The working principle of this embodiment is:

[0032] This embodiment has the function of normally closed on the surface and normally open underwater, wherein Fig. 1 As shown, when the external water depth pressure is relatively small (such as the water surface), the diaphragm 7 remains in a concave state and the inner push rod 8 does not rise. At this time, the first spring washer 111 remains in contact with the lower shell 5, and the first circuit 17 and the second circuit 16 are in an electrically connected state. Specifically, the first circuit 17, the buffer spring 15, the striker column 13, the second spring washer 114, the self-resetting spring 10, the first spring washer 111, the lower shell 5, the upper shell 3, the connecting screw 19, and the second circuit 16 are electrically connected in sequence.

[0033] When the external water depth pressure reaches the requirement (set underwater depth), the diaphragm 7 bulges upward under the action of the external water depth pressure and drives the inner push rod 8 to move upward. At this time, the first spring washer 111 is separated from the lower shell 5, and the non-conductive non-metallic push rod screw 901 realizes the electrical separation of the first spring washer 111 and the inner push rod 8, wherein the first spring washer 111 is fixed on the non-metallic push rod screw 901 and leaves a distance between it and the end face of the inner push rod 8 on the lower side. At this time, the electrical connection is disconnected, and the automatic disconnection function of the present invention is realized.

[0036] The working principle of this embodiment is:

[0037] This embodiment has the function of being normally open on the surface and normally closed underwater, wherein when the external water depth pressure is relatively small (such as the water surface), the diaphragm 7 remains in a concave state and the inner push rod 8 does not rise. At this time, the metal push rod screw 902 and the metal striker 113 are also in a separated state and cannot be electrically connected. When the external water depth pressure reaches the requirement (set underwater depth), the diaphragm 7 bulges upward under the action of the external deep water pressure, and drives the inner push rod 8 to move upward to make the metal push rod screw 902 and the metal striker 113 contact, thereby realizing the automatic closing function of the present invention. Its electrical connection is specifically as follows: the first circuit 17, the buffer spring 15, the striker column 13, the metal striker 113, the metal push rod screw 902, the inner push rod 8, the lower shell 5, the upper shell 3, the connecting screw 19, and the second circuit 16 are electrically connected in sequence.
