[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-5As shown, a marine quick-closing valve safety interlock device includes a quick-closing valve body 1, a handwheel 2, and a docking pipe 3: the handwheel 2 is installed above the quick-closing valve body 1, and the docking pipe 3 is installed on the outer walls of the quick-closing valve body 1 on both sides via flanges. A resistance clamping mechanism 4 is provided above the handwheel 2, an opening and closing control mechanism 5 is provided on the side of the resistance clamping mechanism 4, and a positioning support mechanism 6 is provided below the opening and closing control mechanism 5;

[0024] The resistance clamping mechanism 4 includes a limit plate 41, a positioning support block 42, a micro motor 43, a reciprocating screw 44, a limit bar 45, a limit block 46 and a limit piece 47. The top outer wall of the hand wheel 2 is fitted with a limit plate 41, and the top outer wall of the limit plate 41 is symmetrically provided with positioning support blocks 42. A micro motor 43 is provided on the side outer wall of one of the positioning support blocks 42. The micro motor 43 is connected to one end of the reciprocating screw 44, and the other end of the reciprocating screw 44 is rotatably installed with the side outer wall of the positioning support block 42 away from the position of the micro motor 43. A limit bar 45 is connected between the two positioning support blocks 42. The outside of the reciprocating screw 44 and the limit bar 45 is symmetrically provided with a limit block 46. The bottom outer wall of the limit block 46 is provided with a limit piece 47, and the limit piece 47 is set in an "L" shape.

[0025] When it is necessary to install the device above the quick-closing valve body 1 to clamp and lock the handwheel 2, it is only necessary to turn on the micro motor 43. When the micro motor 43 is turned on, it will automatically drive the reciprocating screw 44 to rotate and then drive the two sets of limit blocks 46 to move in opposite directions. Here, due to the setting of the limit bar 45, the reciprocating screw 44 will only drive the two sets of sliding trajectories to move in the horizontal direction when rotating. Then the movement of the limit block 46 will automatically drive the limit member 47 to move. When the two sets of limit members 47 tightly clamp the handwheel 2, the micro motor 43 is turned off at this time. It is noted that the micro motor 43 has a self-locking function. After closing, the limit member 47 can still maintain the unchanged position after moving. At this point, the locking process of the handwheel 2 is completed so that the subsequent valve opening and closing process can proceed smoothly.

[0026] The opening and closing control mechanism 5 includes a limiting gear ring 51, a limiting gear 52, a support box 53 and a support shaft 54. The side outer wall of the limiting disk 41 is provided with a limiting gear ring 51, and the side of the limiting gear ring 51 is meshed with the limiting gear 52. The bottom outer wall of the limiting gear 52 is in contact with the top outer wall of the support box 53, and the bottom outer wall of the limiting gear 52 located at the axis position is connected to the top outer wall of the support shaft 54. The bottom outer wall of the support shaft 54 ​​is rotatably installed with the bottom inner wall of the support box 53. A limiting worm gear 55 is provided on the outer wall of the support shaft 54 ​​inside the support box 53. The side of the limiting worm gear 55 is connected to a limiting worm 56. One end of the limiting worm 56 is rotatably installed with the side inner wall of the support box 53, and the other end of the limiting worm 56 It is connected to the output end of the drive motor 57, and the drive motor 57 is connected to the side outer wall of the support box 53; when the quick-closing valve body 1 needs to be closed, it is only necessary to turn on the drive motor 57, and then after the drive motor 57 is turned on, it will automatically drive the limiting worm 56 to rotate and then drive the limiting worm gear 55 to rotate, and then the rotation of the limiting worm gear 55 will automatically drive the support shaft 54 ​​to rotate, and then the rotation of the support shaft 54 ​​will automatically drive the limiting gear 52 to rotate and then drive the limiting gear ring 51 to rotate, when the limiting gear ring 51 rotates, it will automatically drive the limiting disk 41 to rotate, at this time, because the limiting mechanism positions the limiting disk 41 above the handwheel 2, and then the rotation of the limiting disk 41 will automatically drive the handwheel 2 to rotate, thereby closing the quick-closing valve body 1.

[0027] The positioning support mechanism 6 includes a first clamping member 61 and a second clamping member 62. The side outer wall of the butt-jointed tube 3 is fitted with the first clamping member 61 and the second clamping member 62, and the first clamping member 61 and the second clamping member 62 are both arranged in a semi-annular structure. The bottom outer wall of the first clamping member 61 and the top outer wall of the second clamping member 62 are both provided with two groups of positioning thread grooves 63. The bottom outer wall of the second clamping member 62 located at the position of the positioning thread groove 63 is correspondingly provided with a nut block 64. The nut block 64 and the fastening bolt 65 are threadedly installed. The top outer wall of the first clamping member 61 is provided with a first support member 66. The top outer wall of the first support member 66 is provided with an electric telescopic rod 67, and the output end of the electric telescopic rod 67 is connected to the bottom outer wall of the support box 53. The bottom end of the second clamping member 62 A second support member 68 is provided on the outer wall, and an auxiliary mounting member 69 is provided on the outer wall at the bottom end of the second support member 68; when the device needs to be positioned outside the docking pipe 3, it is only necessary to adjust the first clamping member 61 and the second clamping member 62 to the appropriate position and then clamp them to the outside of the docking pipe 3, and then use the fastening bolts 65 to pass through the two sets of positioning thread grooves 63 and tighten them with the nut blocks 64 at the corresponding positions. At this point, the device is installed on the outside of the docking pipe 3. Here, the setting of the first support member 66 and the electric telescopic rod 67 has an auxiliary supporting effect on the support box 53, and the auxiliary mounting member 69 at the bottom end of the second support member 68 needs to be fixed to the wall on the side of the quick-closing valve body 1 or above any fixed position plate after the overall debugging of the device is completed, so as to provide a limited and stable support effect for the device.

[0028] When the present invention is in use, it is first necessary to clamp the two sets of limit members 47 at the bottom of the limit plate 41 into the gap of the handwheel 2, and then turn on the micromotor 43 to clamp the limit member 47 to the side of the handwheel 2. When the micromotor 43 is turned on, it will automatically drive the reciprocating screw 44 to rotate and then drive the two sets of limit blocks 46 to move in opposite directions. Here, due to the setting of the limit bar 45, the reciprocating screw 44 will only drive the two sets of sliding trajectories to move in the horizontal direction when rotating. Then the movement of the limit block 46 will automatically drive the limit member 47 to move. When the two sets of limit members 47 tightly clamp the handwheel 2, the micromotor 43 is turned off at this time. It is noted that the micromotor 43 has a self-locking function. After closing, the limit member 47 can still maintain the position after moving. At this point, the locking process of the handwheel 2 is completed so that the subsequent valve opening and closing process can be carried out smoothly.

[0029] Then, according to the installation position of the limit gear ring 51, the first clamping member 61 is adjusted to a suitable position and then clamped to the top of the docking pipe 3. The setting of the electric telescopic rod 67 here is to adjust the limit gear 52 and the limit gear ring 51 to a level height so that the subsequent meshing transmission process can proceed smoothly. When the limit gear ring 51 and the limit gear 52 are adjusted to the meshing state, the second clamping member 62 is clamped to the bottom of the docking pipe 3 and the fastening bolts 65 are used to pass through the two sets of positioning thread grooves 63 and tighten the nut blocks 64 at the corresponding positions. At this point, the device is installed on the outside of the docking pipe 3. Then, the auxiliary mounting member 69 at the bottom end of the second support member 68 is additionally fixed to the wall on the side of the quick-closing valve body 1 or above any fixed position plate, which has the effect of limiting and stabilizing the support of the device.

[0030] When the quick-closing valve body 1 needs to be closed, it is only necessary to turn on the driving motor 57. After the driving motor 57 is turned on, it will automatically drive the limiting worm 56 to rotate and then drive the limiting worm gear 55 to rotate. Subsequently, the rotation of the limiting worm gear 55 will automatically drive the support shaft 54 ​​to rotate. The rotation of the support shaft 54 ​​will automatically drive the limiting gear 52 to rotate and then drive the limiting gear ring 51 to rotate. When the limiting gear ring 51 rotates, it will automatically drive the limiting plate 41 to rotate. At this time, since the limiting mechanism positions the limiting plate 41 above the handwheel 2, the rotation of the limiting plate 41 will automatically drive the handwheel 2 to rotate, thereby closing the quick-closing valve body 1.

[0031] It is noted here that the above-mentioned micro motor 43 and drive motor 57 can be powered by existing technology. Whether it is powered by a power supply component or an external wire, it is all existing conventional operating technical means and will not be described in detail here. If you want to be more intelligent, you can introduce a related intelligent system to control the opening and closing of the drive motor 57 to achieve the effect of remote control of the opening and closing of the quick-closing valve body 1.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
