Description

Technical Field

[0001] This utility model relates to marine engineering, specifically to a passive sealing release device for marine engineering surface communication equipment. Background Technology

[0002] Marine engineering surface communication equipment is designed to operate floating in the vast ocean environment for data collection and transmission. Because it operates in the open ocean, recovering this equipment after its communication mission is complete is extremely costly. However, if not recovered, it will continue to float on the surface, becoming marine debris, and its continued floating also poses a risk of physical damage to ships. Utility Model Content

[0003] This invention proposes a passive seal release device for marine engineering surface communication equipment. The passive seal release device is installed at the water inlet of the surface communication equipment. After the marine engineering surface communication equipment is submerged in seawater, the seawater self-dissolving sheet dissolves within a few hours of contact with the seawater, thus releasing the seal. After the seal is released, seawater enters the marine engineering surface communication equipment, causing it to self-destruct. Simultaneously, the equipment sinks to the seabed after being flooded, preventing it from becoming surface debris. To achieve this objective, the technical solution of this invention is as follows:

[0004] A passive sealing release device for marine engineering surface communication equipment, wherein the outer shell of the marine engineering surface communication equipment is provided with a water inlet communicating with the outside, the sealing release device is installed at the water inlet, and the sealing release device includes a plug and a locking lever.

[0005] The plug is a hollow sleeve with an external hexagon. An annular step is provided inside the plug. A seawater self-dissolving sheet is installed inside the annular step. A first sealing ring is provided between the lower surface of the seawater self-dissolving sheet and the annular step. An annular pressure ring is threaded inside the plug. The annular pressure ring is used to press the seawater self-dissolving sheet. The upper surface of the annular pressure ring has notches on opposite sides.

[0006] The bottom of the locking lever is provided with a plug that matches the notch. The locking lever is inserted into the plug and detachably connected to the annular pressure ring.

[0007] Furthermore, the first sealing ring is made of fluororubber, and the annular pressure ring is made of stainless steel.

[0008] Furthermore, the plug is a T-shaped sleeve composed of two sleeves, one larger than the other, with a second sealing ring on the lower end face of the upper sleeve.

[0009] Furthermore, the locking lever includes a bottom cylinder and a top hexagonal nut, the bottom end of the bottom cylinder is provided with a slotted block, and a limiting protrusion with a diameter larger than that of the bottom cylinder is provided between the bottom cylinder and the top hexagonal nut.

[0010] Furthermore, the plug is equipped with an outer protective sleeve, which consists of a bottom cover and a sealing cover. The sealing cover is sealed to the top of the bottom cover, and 704 silicone is provided at the connection between the sealing cover and the bottom cover.

[0011] Furthermore, the bottom of the cover has parallel cuts on both sides of its outer diameter.

[0012] The contact surfaces of the bottom cover and the sealing cover are provided with interlocking positioning steps;

[0013] The outer diameter of the sealing cap is provided with an axial groove.

[0014] The advantages of this utility model are:

[0015] 1) After the plug of this utility model is installed at the inlet of the marine engineering surface communication equipment, the seawater self-dissolving sheet will dissolve and evaporate upon contact with seawater within a certain period of time (e.g., about 24-48 hours), thereby releasing the seal of the inlet and allowing seawater to enter the equipment. This allows the used surface communication equipment to sink to the seabed, preventing it from becoming surface debris. Furthermore, after seawater enters the marine engineering surface communication equipment, it comes into contact with the internal electronic components. Due to the corrosive nature of seawater, the electronic components and structural parts inside the equipment slowly corrode and degrade, preventing them from becoming permanent waste and achieving a mutually beneficial relationship with the marine ecosystem.

[0016] 2) The "I"-shaped insert at the bottom of the locking lever engages with the notch of the annular pressure ring. The seawater self-dissolving sheet can be tightened by rotating and locking the lever with a torque wrench, simplifying the installation process.

[0017] 3) Corrosion-resistant material selection: The annular pressure ring is made of 316L alloy steel to prevent corrosion and lock the seawater self-dissolving sheet. The first sealing ring is made of fluororubber to ensure good sealing. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0029] This utility model provides a passive sealing release device for marine engineering surface communication equipment. The passive sealing release device includes a plug 10 and a locking lever 20. In addition, the plug 10 is also equipped with an outer protective sleeve 30 for transporting and storing the plug 10.

[0030] After the plug 10 of this invention is installed at the inlet of the marine engineering surface communication equipment, the seawater self-dissolving sheet will dissolve and evaporate after a few hours upon contact with seawater, thereby releasing the seal of the inlet and allowing seawater to enter the equipment. Ultimately, the surface communication equipment can be sunk to the seabed, preventing it from becoming surface debris. Furthermore, after the seawater enters the marine engineering surface communication equipment, it comes into contact with the internal electronic components. Since all components of this invention are made of biodegradable materials, the corrosiveness of seawater causes the electronic components and structural parts inside the equipment to slowly corrode and degrade, preventing them from becoming permanent waste and achieving a marine ecologically friendly coexistence.

[0031] It should be noted that the time required for the seawater self-dissolving tablet to dissolve is much longer than the time required for marine engineering surface communication equipment to collect and transmit data, therefore it does not affect the data collection and transmission of the surface communication equipment.

[0032] 10 plugs

[0033] The plug 10 is a one-piece molded "T"-shaped sleeve. The "T"-shaped sleeve has a larger upper sleeve 101 and a smaller lower sleeve 102. The top of the upper sleeve 101 has an external hexagon 103 for engaging with a clamp (or wrench). The lower end face of the upper sleeve 101 has a second sealing ring 15, which ensures a seal between the plug 10 and the water inlet.

[0034] An annular step 11 for fixing the seawater self-dissolving plate 1 is provided inside the plug 10 (e.g., Figure 6 A first sealing ring 12 made of fluororubber is provided between the lower surface of the seawater self-dissolving sheet 1 and the bottom of the annular step 11. A stainless steel annular pressure ring 13 is installed in the internal thread of the plug 10. The annular pressure ring 13 is used to press the seawater self-dissolving sheet 1. The upper surface of the annular pressure ring 13 is provided with a notch 14 on the opposite side.

[0035] Locking lever 20

[0036] The locking lever 20 includes a bottom cylinder 21 and a top hexagonal nut 22. The bottom end of the bottom cylinder 21 is provided with a "I"-shaped insert 23. A limiting protrusion 24 with a diameter larger than that of the bottom cylinder 21 is provided between the bottom cylinder 21 and the top hexagonal nut 22.

[0037] After installing the seawater self-dissolving tablet 1 onto the plug 10 and screwing it into the annular pressure ring 13, insert the bottom insert 23 of the locking lever 20 into the notch 14 of the annular pressure ring 13. The width of the insert 23 matches the width of the notch 14, allowing the locking lever 20 to be inserted and rotate the annular pressure ring 13. Secure the plug 10 with a clamp or a first wrench, then clamp the torque wrench onto the top hexagonal nut 22. The torque wrench rotates the locking lever 20 and the annular pressure ring 13, gradually tightening the seawater self-dissolving tablet within the plug 10 as the annular pressure ring 13 rotates. Once fully tightened, remove the locking lever 20.

[0038] If a torque wrench is not available, a regular wrench can be used to rotate the locking lever 20. The locking lever 20 is limited in length by the limiting ring 24 to prevent over-tightening and damage to the seawater self-dissolving tablet.

[0039] Outer protective sleeve 30

[0040] After the seawater self-dissolving tablet is fixedly installed onto the plug 10, during the storage and transportation of the plug 10, the plug 10 can be placed inside the outer protective sleeve 30 to isolate the seawater self-dissolving tablet from the outside air and prevent evaporation. Figure 7-8As shown, the outer protective sleeve 30 of this utility model consists of a bottom cover 31 and a sealing cover 32. The sealing cover 32 is sealed to the top of the bottom cover 31, and a sealant is provided at the connection between the sealing cover 32 and the bottom cover 31. In an optional embodiment, the sealant is 704 silicone. 704 silicone has good weather resistance and aging resistance, and can maintain a stable sealing effect over a wide temperature range. In addition, 704 silicone also has good adhesion, which can firmly bond the sealing cover 32 to the bottom cover 31, further enhancing the sealing performance of the outer protective sleeve 30.

[0041] The bottom cover 31 has parallel cutouts 33 on both sides of its outer diameter, which facilitates fixing the bottom cover 31 to a clamp or wrench, so that the bottom cover 31 remains stationary when rotating the sealing cover 32, making it easy to open the outer protective sleeve 30. Furthermore, the outer diameter of the sealing cover 32 has an axial groove 34, which increases friction, making it easier to apply force when rotating the sealing cover 32 and preventing slippage; in addition, the groove 34 on the sealing cover 32 also acts as a reinforcing rib, thereby improving the strength of the sealing cover 32.

[0042] The contact surfaces of the bottom cover 31 and the sealing cover 32 are provided with interlocking positioning steps, which can quickly align and install the sealing cover 32 on the bottom cover 31 and the top, while preventing the sealing cover 32 from shifting.

[0043] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a conventional manner within the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this utility model using the disclosed methods and techniques, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. This does not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
