Description

Technical Field

[0001] The utility model relates to the field of waterproof device sealing, in particular to a sealing structure of a waterproof device. Background Art

[0002] The waterproof sealing of underwater motion mechanisms has always been a critical issue. The quality of the waterproofing can directly affect the normal operation of the underwater motion mechanism. If the waterproof sealing structure leaks, it will cause damage to the electronic components, hydraulic valves and other precision parts of the motion mechanism, or even directly scrap it. The sealing structure needs to be installed underwater for a long time, and the materials used cannot be corroded or dissolved by water. The sealing structure must be able to resist the axial tensile forces caused by the movement. At the same time, the underwater motion mechanism needs to move continuously. The waterproof device cannot be a purely rigid component, and its position and shape must follow the moving parts. The underwater motion mechanism will generate a large lateral tensile force on the waterproof device when it moves. The waterproof device must be able to resist such large lateral tensile forces. At the same time, if the underwater motion mechanism moves, the waterproof device must be able to resist such large lateral tensile forces. At the same time, if the waterproof device leaks in extreme cases during the movement of the underwater motion mechanism, it must generate a feedback signal in a timely manner and drain a large amount of water in a timely manner. The existing waterproof device sealing structure of underwater motion mechanisms has a relatively mediocre sealing effect, and its anti-loosening and anti-leakage effects are relatively mediocre. The ability to resist the large lateral tensile forces generated by underwater motion is poor, which may cause leakage. How to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a sealing structure of a waterproof device, which aims to improve the sealing effect of the existing waterproof device sealing structure of the underwater sports mechanism, which is relatively general, has poor ability to resist the large lateral pulling force generated by underwater sports, and may cause water leakage.

[0004] The utility model is implemented as follows: a sealing structure of a waterproof device, including a moving mechanism, a fixed component is provided on the outside of the moving mechanism, a sealing structure is installed on one end of the fixed component, and a waterproof bag is sealed and fixed to the outside of the fixed component through the sealing structure; the sealing structure includes a self-adhesive butyl rubber putty sheet, the self-adhesive butyl rubber putty sheet is provided at one end of the fixed component, a waterproof bag edge is formed on the waterproof bag corresponding to the position of the self-adhesive butyl rubber putty sheet, a waterproof water-stopping sponge is provided at one end of the waterproof bag edge, a double convex pressure plate is provided at one end of the waterproof water-stopping sponge, the double convex pressure plate, the waterproof water-stopping sponge, the waterproof bag edge and the self-adhesive butyl rubber putty sheet are all provided with adaptive thread grooves and are fixed by hexagonal cylindrical head bolts.

[0005] In the preferred technical solution of the present invention, a wedge-shaped anti-loosening washer is arranged between the hexagonal cylindrical head bolt and the double-convex pressure plate. The waterproof bag edge is fixed by the hexagonal cylindrical head bolt, wedge-shaped anti-loosening washer, double-convex pressure plate, waterproof water-stopping sponge and self-adhesive butyl rubber putty sheet. The double-convex pressure plate presses the waterproof bag edge, waterproof water-stopping sponge and self-adhesive butyl rubber putty sheet into the groove of the moving mechanism, thereby increasing the stability of the entire sealing structure and being able to withstand large lateral tension. The self-adhesive butyl rubber putty sheet has very good fluidity. It can not only fill the gap in the installation, but also flow into the threaded hole, thereby preventing the hexagonal cylindrical head bolt from loosening. The self-adhesive butyl rubber putty sheet has good adhesion and can be directly adhered to the installation surface of the fixed component, thereby playing a good waterproof and water-stopping role.

[0006] In the preferred technical solution of the present invention, the wedge-shaped anti-loosening washers are provided in two groups and the two groups of the wedge-shaped anti-loosening washers are provided as mutually engaging surface washers. One end of the wedge-shaped anti-loosening washers of one group is provided as a wedge-shaped tooth surface, and the other end of the wedge-shaped anti-loosening washers of the other group is provided as radial fine teeth. When the waterproof bag moves with the underwater motion mechanism, the waterproof bag will generate vibration and impact force on the entire sealing structure. The wedge-shaped anti-loosening washer, since it itself is composed of a pair of mutually engaging surface washers, can effectively prevent the hexagon socket head bolts from loosening due to vibration.

[0007] In the preferred technical solution of the present invention, the upper end of the hexagon socket cylindrical head bolt is set to be circular, and the upper end of the hexagon socket cylindrical head bolt is circular and has no sharp corners, so as to prevent the hexagon socket cylindrical head bolt from contacting and rubbing with the waterproof bag and causing damage to the waterproof bag. The sealing structure adopts a variety of special sealing combinations, which have been verified by tests and can be used underwater for a long time without leakage.

[0008] In the preferred technical solution of the present invention, the waterproof bag is set to a flexible material, and the device is installed in a water depth environment of 1-5 meters. When the moving mechanism moves, the waterproof device will move with the moving mechanism. The waterproof bag is set to a polyurethane or rubber-clad flexible material. The material itself has good stability, resilience and tensile strength, and can be used in an underwater environment for a long time.

[0009] In the preferred technical solution of the present invention, the waterproof bag is provided with a visual monitoring component, which can transmit the visual image in the flexible waterproof device to the monitoring room, so that personnel can detect it in time once a water leakage is found.

[0010] In the preferred technical solution of the present invention, the waterproof bag is provided with a wired water leakage sensor. Since the wired water leakage sensor has strong mechanical properties and wear resistance, it can transmit electrical signals in time and even generate sound alarms when water seepage and leakage occur.

[0011] The beneficial effects of the present invention are as follows: the present invention obtains a sealing structure of a waterproof device through the above-mentioned design. When the moving mechanism moves, the waterproof device will move with the moving mechanism. The waterproof bag is fixed by the cooperation of the hexagonal cylindrical head bolt, the wedge-shaped anti-loosening washer, the double-convex pressure plate, the waterproof water-stopping sponge and the self-adhesive butyl rubber putty sheet, so that the waterproof bag is sealed and fixed to the outside of the fixed component. The double-convex pressure plate fixes the waterproof bag, the waterproof water-stopping sponge and the self-adhesive butyl rubber putty sheet, thereby increasing the stability of the entire sealing structure and being able to resist large lateral tension. The self-adhesive butyl rubber putty sheet has a good waterproof and water-stopping effect. When the waterproof bag moves with the underwater moving mechanism, the waterproof bag will generate vibration and impact force on the entire sealing structure. The wedge-shaped anti-loosening washer, since it itself is composed of a pair of mutually biting eating washers, can effectively prevent the hexagonal cylindrical head bolt from loosening due to vibration.

[0019] In some specific embodiments, a wedge-shaped anti-loosening washer 320 is provided between the hexagon socket head bolt 310 and the double convex pressure plate 330, and the waterproof bag edge 350 is fixed by the hexagon socket head bolt 310, the wedge-shaped anti-loosening washer 320, the double convex pressure plate 330, the waterproof water-stopping sponge 340 and the self-adhesive butyl rubber putty sheet 360, so that the waterproof bag 200 is sealed and fixed to the outside of the fixed component 110, and the double convex pressure plate 330 fixes the waterproof bag edge 350, the waterproof water-stopping sponge 340 and the self-adhesive butyl rubber putty sheet 360. The butyl rubber putty sheet 360 is pressed into the groove of the moving mechanism 100, which increases the stability of the entire sealing structure 300 and can withstand large lateral tension. The self-adhesive butyl rubber putty sheet 360 has very good fluidity. It can not only fill the gap during installation, but also flow into the threaded hole to prevent the hexagon socket head bolt 310 from loosening. The self-adhesive butyl rubber putty sheet 360 has good adhesion and can be directly adhered to the installation surface of the fixed component 110, playing a good waterproof and water-stopping role.

[0020] In some specific embodiments, the wedge-shaped anti-loosening washers 320 are set as two groups and the two groups of wedge-shaped anti-loosening washers 320 are set as mutually engaging eating washers. One end of one group of wedge-shaped anti-loosening washers 320 is set as a wedge-shaped tooth surface, and the other end of the other group of wedge-shaped anti-loosening washers 320 is set as radial fine teeth. When the waterproof bag moves with the underwater motion mechanism, the waterproof bag will generate vibration and impact force on the entire sealing structure 300. The wedge-shaped anti-loosening washer 320, because it itself is composed of a pair of mutually engaging eating washers, can effectively prevent the hexagon socket head bolt 310 from loosening due to vibration.

[0021] In some specific implementation schemes, the upper end of the hexagon socket head bolt 310 is set to be circular. The upper end of the hexagon socket head bolt 310 is circular and has no sharp corners to prevent the hexagon socket head bolt 310 from contacting and rubbing with the waterproof bag and causing damage to the waterproof bag. The sealing structure 300 adopts a variety of special sealing combinations, which have been verified by tests and can be used underwater for a long time without leakage.

[0022] In some specific embodiments, the waterproof bag 200 is set to a flexible material, and the device is installed in a water depth environment of 1-5 meters.

The material itself has good stability, resilience and tensile strength, and can be used in an underwater environment for a long time.

[0023] In some specific embodiments, the waterproof bag 200 is provided with a visual monitoring component (not shown in the figure). The visual monitoring component is located on the side of the waterproof bag 200 close to the waterless space. The visual monitoring component can transmit the visual image in the flexible waterproof device to the monitoring room. Once a water leakage is found, personnel can detect it in time. The visual monitoring component can be a miniature wide-angle monitor.

[0024] In some specific implementation schemes, the waterproof bag 200 is provided with a wired water leakage sensor (not shown in the figure). The wired water leakage sensor is located on the side of the waterproof bag 200 close to the waterless space. The wired water leakage sensor is installed on the waterproof bag 200 by pasting. Since the wired water leakage sensor has strong mechanical properties and wear resistance, it can transmit electrical signals in time and even generate sound alarms when water seepage and leakage occur.

[0025] Working principle: When the motion mechanism 100 is in motion, the waterproof device will move with the motion mechanism 100, and the waterproof bag edge 350 will be fixed by the hexagon socket head bolt 310, wedge-shaped anti-loosening washer 320, double convex pressure plate 330, waterproof water-stopping sponge 340 and self-adhesive butyl rubber putty sheet 360, so that the waterproof bag 200 is sealed and fixed to the outside of the fixed component 110, and the motion mechanism 100 is operated in a certain way. The double convex pressure plate 330 fixes the waterproof bag edge 350, the waterproof water-stopping sponge 340 and the self-adhesive butyl rubber putty sheet 360 increase the stability of the entire sealing structure 300 and can withstand large lateral tension. The self-adhesive butyl rubber putty sheet 360 plays a good waterproof and water-stopping role. When the waterproof bag moves with the underwater motion mechanism, the waterproof bag will generate vibration and impact force on the entire sealing structure 300. The wedge-shaped anti-loosening washer 320, because it itself consists of a pair of mutually interlocking eating washers, can effectively prevent the hexagon socket head bolt 310 from loosening due to vibration.
