[0048] Please refer to Figure 3 The spraying mechanism 1 provided by the embodiment can be conveniently carried, and the structure of the spraying mechanism 1 for providing power to the blocking object 331 is optimized and improved.

[0049] In the embodiment, the containing member 111 is a bottle body or a tank body, the output portion 112 is a bottle opening or a tank opening, and the spraying object is compressed air or other compressed objects, but the embodiment is not limited thereto.

[0050] Please refer to Figure 5 and Figure 6 Optionally, the energy storage assembly 11 further includes a connecting member 113 and a cover member 114. The connecting member 113 includes a first end 1131 and a second end 1132 opposite to each other. The first end 1131 is connected to the output portion 112, and the second end 1132 is arranged close to the moving portion 133. The second end 1132 is connected to the cover member 114. The first end 1131 is in communication with the second end 1132, and the first end 1131 is provided with a ring wall 1133 extending radially along the output portion 112. The ring wall 1133 is provided with a ring opening 1134, and the diameter of the ring opening 1134 is smaller than that of the bottle opening. The cover member 114 is provided with a through hole 1141 to communicate the first end 1131 and the second end 1132. In this way, the connecting member 113 and the cover member 114 can buffer the spraying object when the spraying object is sprayed from the output portion 112, so as to avoid that the impact force of the spraying object is too large to damage the shell member 121.

[0051] Optionally, the connecting member 113 can be a double-end nut, and the cover member 114 can be a nut. One end of the double-end nut is threadedly connected to the nut, and the other end of the double-end nut is threadedly connected to the output portion 112. However, the embodiment is not limited thereto.

[0052] The surface of the cover 114 close to the moving part 133 is contoured with the moving part 133, and the moving part 133 can contact the surface of the cover 114 when moving up and down, so as to avoid the moving part 133 directly contacting the output part 112. The cover 114 is used to protect the output part 112 and the moving part 133, and avoid mutual damage when touching.

[0053] The sealing part 132 includes a sealing plug 1321 and a gasket 1322. The sealing plug 1321 is arranged at the first end 1131, and extends along the radial direction of the output part 112, and is used to fit the ring wall 1133 to close the ring opening 1134 so as to close the output part 112. The gasket 1322 is arranged between the sealing plug 1321 and the ring wall 1133, and has elasticity, and is used to further press the ring wall 1133 to close the ring opening 1134.

[0054] Please refer to Figure 7 The moving part 133 includes a first flange 1331, a second flange 1332, and an intermediate segment 1333. The first flange 1331 and the second flange 1332 are arranged at intervals, and the intermediate segment 1333 connects the first flange 1331 and the second flange 1332. The first flange 1331 is connected with the first elastic member 134, and the second flange 1332 is connected with the cover 114. The first flange 1331 and the second flange 1332 are arranged at two opposite sides of the cover 114, and the intermediate segment 1333 is arranged in the through hole 1141 of the cover 114. The first flange 1331 and the second flange 1332 protrude along the radial direction of the cover 114, and are used for limiting so that the moving part 133 is movably clamped to the cover 114. In this way, the position accuracy of the moving part 133 can be improved, and the repeated movement of the moving part 133 and the abutting of the moving part 133 with the movable part 136 are facilitated.

[0055] Please refer to Figure 5 The first elastic member 134 can use a spring or other elastic part, and the present embodiment is not limited thereto.

[0056] In a possible implementation, the first elastic member 134 is connected to the end of the moving part 133 away from the sealing part 132. When the movable part 136 moves towards the first elastic member 134, the movable part 136 abuts the moving part 133 to drive the sealing part 132 to move to close the output part 112, and the moving part 133 presses the first elastic member 134.

[0057] In the embodiment, the first elastic member 134 abuts against the moving part 133 downward, and the movable member 136 abuts against the moving part 133 upward. When the ejection mechanism 1 does not need to drive the barrier 331 to move, the movable member 136 moves upward to drive the valve core member 131 to move upward so that the sealing part 132 closes the output part 112, thereby closing the containing part 111 to prevent the ejection from being ejected from the ejection mechanism 1, and the valve core member 131 presses the first elastic member 134. When the ejection mechanism 1 needs to drive the barrier 331 to move, the movable member 136 moves downward, and the first elastic member 134 drives the valve core member 131 to move downward so that the sealing part 132 opens the output part 112, thereby opening the containing part 111 to allow the ejection to be ejected from the ejection mechanism 1. In this way, the ejection mechanism 1 has a simple structure and is convenient to carry.

[0058] In other embodiments, the first elastic member 134 abuts against the moving part 133 upward, and the movable member 136 abuts against the moving part 133 downward. The movable member 136 moves upward to drive the valve core member 131 to move upward so that the output part 112 is opened, thereby driving the barrier 331 to move. The movable member 136 moves downward to close the output part 112, thereby stopping the ejection mechanism 1 from moving, and the valve core member 131 presses the first elastic member 134. It can be understood that the first elastic member 134 and the movable member 136 can be arranged in various ways as long as they can cooperate to move the valve core member 131 to open or close the output part 112.

[0059] In a possible implementation, the ejection member 122 comprises a one-way valve 1221 arranged in the closed cavity 125. When the output part 112 is opened, the one-way valve 1221 connects the closed cavity 125 with the outside, and when the output part 112 is closed, the one-way valve 1221 blocks the connection between the closed cavity 125 and the outside.

[0060] In the embodiment, the one-way valve 1221 can prevent water from flowing back into the closed cavity 125 when the ejection mechanism 1 moves in the water, thereby affecting the movement of the valve core member 131, and improving the stability of the ejection mechanism 1 and the ejection efficiency.

[0061] In a possible implementation, the valve assembly 13 further comprises a second elastic member 135 elastically abutting against one end of the moving part 133 opposite to the first elastic member 134, and the second elastic member 135 and the movable member 136 jointly abut against one side of the moving part 133.

[0062] In the embodiment, the second elastic member 135 is a spring, and the second elastic member 135 is used to abut against the moving part 133 together with the movable member 136. In this way, the force applied by the movable member 136 to the moving part 133 can be reduced when the movable member 136 abuts against the moving part 133.

[0063] Optionally, the elastic force of the second elastic member 135 is smaller than the elastic force of the first elastic member 134. When the moving part 133 is not pressed by the moving member 136, the first elastic member 134 can overcome the force of the first elastic member 134 to move the moving part 133 downward to close the output part 112. The arrangement of the first elastic member 134 and the second elastic member 135 facilitates flexible and fast movement of the valve assembly 13, and the simple structure of the valve assembly 13 facilitates the simple structure of the spraying mechanism 1 for easy carrying.

[0064] Please refer to Figure 4 FIG. 2, in one possible implementation, the moving member 136 includes a cam 1361, a slider 1362, a crank 1363, and a rocker 1364. The peripheral surface of the cam 1361 is rotatably pressed against the moving part 133, and the cam 1361 can rotate to move the moving part 133.

[0065] In this embodiment, the peripheral surface of the cam 1361 is rotatably pressed against the moving part 133. The rocker 1364 is in transmission connection with the cam 1361, and the rocker 1364 can be forced to rotate the cam 1361. The rocker 1364 rotates the cam 1361 through the slider 1362 and the crank 1363. The cross section of the cam 1361 can be elliptical, and the convex end of the cam 1361 protrudes in the circumferential direction of the cam 1361. The convex end is pressed against the moving part 133 to move upward to close the output part 112. When the convex end of the cam 1361 rotates away from the moving part 133, the first elastic member 134 presses the moving part 133 to move downward to open the output part 112.

[0066] In one possible implementation, the rocker 1364 includes a connecting end 1365 and a pushing end 1366. The connecting end 1365 is in transmission connection with the cam 1361, and the pushing end 1366 extends from the connecting end 1365 to the shell 121 and penetrates the shell 121. The pushing end 1366 is in movable connection with the shell 121.

[0067] In this embodiment, the tractor 2 is arranged in the launching cabin 31, and the pushing end 1366 is pressed against the side wall 311 of the launching cabin 31 to close the output part 112. The pushing member 32 is arranged in the launching cabin 31, and the pushing member 32 is used to push the tractor 2 to move and separate the rocker 1364 from the launching cabin 31. The first elastic member 134 presses the moving part 133 to move downward to open the output part 112.

[0068] Please refer to Figure 1 and Figure 8 In one possible implementation, the blocking device 3 further includes a driving assembly 34 connected to the net cabin 33. The driving assembly 34 is used to move the net cabin 33.

[0069] In the embodiment, the driving assembly 34 comprises an acoustic detector 341, a controller 342, a battery 343, a rudder 344 and propellers 346. The acoustic detector is arranged at the front end of the blocking device 3, and is used to emit ultrasonic signals to detect the water area. The controller 342 is electrically connected with the acoustic detector 341, and generates a navigation route according to the detection signal of the acoustic detector 341, for moving the blocking device 3. The battery 343 provides power for the acoustic detector 341 and the controller 342 to work. The rudder 344 comprises a plurality of rudder bodies 345, which are used to adjust the moving posture of the blocking device 3. A plurality of propellers 346 are distributed at the tail end of the net cabin 33, and are used to push the blocking device 3 to move. By arranging the driving assembly 34, the blocking device 3 can move flexibly and quickly in the water area, so as to implement the blocking operation flexibly and efficiently.

[0070] When it is needed to intercept a ship or a speedboat, the blocking device 3 is moved to the vicinity of the ship or the speedboat by the propellers 346, the posture of the blocking device 3 is adjusted by the rudder bodies 345 so that the two groups of launching cabins 31 are vertical, the launching cabin 31 pushes the tractor 2 out of the cabin by the pushing piece 32, and the actuating end 1366 of the rocker 1364 is separated from the side wall 311 of the launching cabin 31, so that the output part 112 of the jet mechanism 1 is opened, the tractor 2 is ejected out of the cabin under the action of the jet mechanism 1, and the blocking object 331 is pulled out of the net cabin 33.

[0071] Optionally, the tractors 2 are connected with air bags 24, the tractors 2 close to the upper side of the blocking device 3 are provided with the air bags 24, and the air bags 24 are inflated after the tractors 2 leave the net cabin 33, so that the tractors 2 close to the upper side float upward to pull the blocking object 331 to expand upward. The tractors 2 close to the lower side of the blocking device 3 are not connected with the air bags 24 or other suspensions, so that the tractors 2 close to the lower side sink downward to pull the blocking object 331 to expand further, so as to achieve the effect that the tractors 2 are launched flexibly and efficiently by the blocking device 3.

[0072] Please refer to Figure 9 When it is needed to intercept a frogman or other target object, the posture of the blocking device 3 is adjusted so that the two groups of launching cabins 31 are horizontal, the tractors 2 are launched above the frogman, and the blocking object 331 is pulled open. The blocking object 331 close to the middle part is made of light material, and the blocking object 331 close to the edge part is made of heavy material. After the blocking object 331 is suspended in water, the blocking object 331 sinks around the middle part due to different buoyancy. The net cabin 33 of the blocking device 3 tightens the traction rope 332, the lower part of the blocking object 331 is gradually retracted, and the blocking object 331 is in a pocket shape to envelope and capture the target object.

[0073] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application, and although the present application is explained in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or equivalent replaced without departing from the spirit and scope of the technical solutions of the present application.
