Description

Technical Field

[0001] This invention relates to the field of ship design technology, and in particular to a snap-fit ​​filter funnel for a vent. Background Technology

[0002] In ship design, various oil, water, and gas systems are crucial for the stable operation of the vessel. However, these systems may leak oil or water during operation and maintenance, polluting the engine room environment. To control the contaminated area, ship design often employs the method of adding a confining enclosure to prevent the spread of leaked liquids, and vent pipes are installed inside the confining enclosure to guide the leaked liquid to a designated compartment, thereby reducing the amount of manual cleanup work for the crew.

[0003] Currently, existing venting systems are typically exposed without any protective measures. Dust or fallen solid debris from the conduit can easily enter the vent pipe and accumulate, leading to blockages. To meet the specific requirements of some shipowners, shipyards design temporary, non-fixed filter funnels. However, these funnels may be misaligned during installation, resulting in excessive gaps between them and the vent, affecting filtration efficiency, or they may be washed away by excessive liquid discharge, losing their filtration function. Therefore, to address these problems and shortcomings, a clamping filter funnel for venting systems needs to be designed to fill this gap. Summary of the Invention

[0004] The purpose of this invention is to design a clamping filter funnel for a discharge port that can solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides a snap-fit ​​filter funnel for a discharge port, the discharge port comprising a vertically extending discharge pipe and a discharge opening, the discharge opening being connected to the upper end of the discharge pipe, characterized in that it comprises:

[0007] A top cover is provided on the opening of the funnel body, and the top cover has a connecting hole and a leakage hole that run through the vertical direction.

[0008] An operating component is slidably inserted through the connecting hole. The end of the operating component protruding above the top cover is provided with a handle, and the end of the operating component protruding below the top cover is provided with a locking part. An elastic element is connected between the locking part and the top cover.

[0009] At least one pair of positioning elements are provided, each of which is slidably inserted into the positioning through hole. One end of the positioning element inside the funnel body is connected to the locking part, and the other end of the positioning element outside the funnel body is provided with a locking part.

[0010] In the initial state, the elastic element undergoes elastic deformation, driving the locking part to move away from the top cover. The locking part causes the positioning part to slide away from the funnel body, and the locking member abuts against the wall of the discharge pipe. Pulling the handle upwards converts it to a separated state. In the separated state, the locking part moves towards the top cover under the action of external force, and the locking part causes the positioning part to slide towards the funnel body, and the locking member separates from the wall of the discharge pipe.

[0011] Furthermore, the funnel body has an abutment portion around its opening edge, the outer diameter of which is larger than the outer diameter of the discharge pipe, and the abutment portion is detachably connected to the top cover.

[0012] Furthermore, the positioning element is a spring sheet, the snap-fit ​​element is hemispherical, and the arc surface of the snap-fit ​​element is disposed facing the pipe wall of the discharge pipe.

[0013] Furthermore, the handle portion is ring-shaped.

[0014] Furthermore, the operating component includes a connecting rod that slides through the connecting hole, the upper end of the connecting rod being detachably connected to the handle portion, and the lower end of the connecting rod being fixedly connected to the locking portion.

[0015] Furthermore, the elastic element is a spring, and the elastic element is sleeved on the connecting rod.

[0016] Furthermore, the lower end of the handle is connected to an internally threaded lock nut, and the upper end of the connecting rod is provided with an external thread. The connecting rod is connected to the internally threaded lock nut through the external thread.

[0017] Furthermore, the top cover has a plurality of leakage holes, adjacent leakage holes are equally spaced along the circumference of the top cover, and the connecting hole is located on the central axis of the top cover.

[0018] Furthermore, the sieve holes are arranged in an array on the lower peripheral wall of the funnel body and on the bottom of the funnel body, and the positioning through hole is located above the sieve holes.

[0019] Furthermore, the aperture size of the sieve hole is R mm, and the distance between the center points of adjacent sieve holes is L mm, where 2.5 ≤ R ≤ 3.5 and 4.5 ≤ L ≤ 5.5.

[0020] Compared with the prior art, the clamping filter funnel for the discharge port according to an embodiment of the present invention has the following advantages:

[0021] The clamping filter funnel for the vent of this invention is used to filter impurities at the vent of the circlip, and also has a clamping function to prevent the filter funnel from falling out and losing its function due to objective factors.

Detailed Implementation

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0033] In the description of this invention, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In this invention, the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0035] Reference Figure 1 and Figure 2 An embodiment of the present invention provides a clamping filter funnel for a discharge port, the discharge port comprising a vertically extending discharge pipe 1 and a discharge opening 10, the discharge opening 10 being connected to the upper end of the discharge pipe 1, characterized in that it comprises:

[0036] The funnel body 2 has its opening facing upwards. At least one pair of opposing positioning through holes 21 are provided on the side wall of the funnel body 2. A plurality of sieve holes 22 are provided at the lower part of the funnel body 2. The funnel body 2 is placed inside the upper end of the discharge pipe 1 through the discharge opening 10.

[0037] The top cover 3 is placed over the opening of the funnel body 2. The top cover 3 has a connecting hole 31 and a leakage hole 32 that run through the vertical direction.

[0038] The control element 4 is slidably inserted through the connection hole 31. The end of the control element 4 protruding above the top cover 3 is provided with a handle part 41, and the end of the control element 4 protruding below the top cover 3 is provided with a locking part 42. An elastic element 5 is connected between the locking part 42 and the top cover 3.

[0039] At least one pair of positioning elements 6 are provided, each of which is slidably inserted into the positioning through hole 21. One end of the positioning element 6 inside the funnel body 2 is connected to the locking part 42, and the other end of the positioning element 6 outside the funnel body 2 is provided with a locking member 7. Specifically, the number of positioning elements 6 is the same as the number of positioning through holes 21.

[0040] In the initial state, the elastic element 5 undergoes elastic deformation, driving the locking part 42 to move away from the top cover 3. The locking part 42 drives the positioning element 6 to slide away from the funnel body 2, and the locking element 7 abuts against the wall of the discharge pipe 1. Pulling the handle part 41 upward converts it to a separated state. In the separated state, the locking part 42 moves towards the top cover 3 under the action of external force, and the locking part 42 drives the positioning element 6 to slide towards the funnel body 2. The locking element 7 separates from the wall of the discharge pipe 1.

[0041] This application can filter impurities at the discharge port of the filter tray. In the initial state, the elastic element 5 deforms and applies force to make the locking element 7 lock with the wall of the discharge pipe 1, preventing the filter funnel from falling out due to objective factors and losing its function. When the external force pulls the operating element 4, the funnel changes to the separation state, and the locking element 7 separates from the wall of the discharge pipe 1, making it convenient to take out the funnel.

[0042] In some improvements of this application, the opening edge of the funnel body 2 is provided with an abutment portion 23. The outer diameter of the abutment portion 23 is larger than the outer diameter of the discharge pipe 1, and the abutment portion 23 is detachably connected to the top cover 3. Specifically, the funnel body 2 and the abutment portion 23 are integral parts with a smooth transition. The abutment portion 23 is used to abut against the pipe opening 10 of the discharge pipe 1, so that the funnel can be stuck at the discharge opening 10 and will not fall into the discharge pipe 1. At the same time, it avoids the interference of the weld of the discharge pipe 1 on the installation, which is conducive to liquid discharge. In a specific embodiment of this application, the top cover 3 and the funnel body 2 are detachably connected by countersunk screws installed at the abutment portion 23, which facilitates the removal of the top cover 3 for cleaning and maintenance of the top cover 3 and the funnel body 2.

[0043] In some improvements of this application, the positioning element 6 is a spring sheet, and the snap-fit ​​element 7 is hemispherical, with the arc surface of the snap-fit ​​element 7 facing the wall of the discharge pipe. In this embodiment, the spring sheet is an arc-shaped spring sheet with a certain rigidity, allowing it to bend and pass through the positioning through-hole 21 to snap the snap-fit ​​element 7 against the wall of the discharge pipe. The hemispherical snap-fit ​​element 7 design reduces friction between the snap-fit ​​element 7 and the wall of the discharge pipe 1.

[0044] In some improvements of this application, the handle portion 41 is ring-shaped, and the ring-shaped operating member 4 facilitates the direct pulling of the operating member 4 by a hook-shaped tool or hand.

[0045] In some improvements of this application, the operating component 4 includes a connecting rod 43, which slides through the connecting hole 31. The upper end of the connecting rod 43 is detachably connected to the handle portion 41, and the lower end of the connecting rod 43 is fixedly connected to the locking portion 42. The operating component 4 is mainly assembled from the connecting rod 43 and the handle portion 41, which allows for easy disassembly and separation of the connecting rod 43 and the handle portion 41, thereby enabling the separation of the top cover 3 from the funnel body 2 and cleaning the impurities accumulated inside the funnel body 2.

[0046] Reference Figure 5 As shown, in some improvements of this application, the elastic element 5 is a spring, the elastic element 5 is sleeved on the connecting rod 43, and the shape of the locking part 42 can be designed as a disc larger than the outer diameter of the spring, serving as the base of the spring to position the spring and compress the spring.

[0047] Reference Figure 6 As shown, in some improvements of this application, the lower end of the handle 41 is connected to an internally threaded lock nut, and the upper end of the connecting rod 43 is provided with an external thread. The connecting rod 43 is connected to the internally threaded lock nut through the external thread. By rotating the handle 41, the handle 41 can be easily separated from the connecting rod 43, thereby separating the top cover 3 from the funnel body 2, and cleaning the inside of the funnel body 2 and the top cover 3.

[0048] Reference Figure 4 As shown, in some improvements of this application, the top cover 3 is provided with a plurality of leakage holes 32, and adjacent leakage holes 32 are equally spaced along the circumference of the top cover 3, and the connecting hole 31 is located on the central axis of the top cover 3. In a specific embodiment of this application, the leakage holes 32 are elongated petal-shaped, and when viewed from above, the leakage holes 32 and the circular connecting hole 31 form the shape of a flower, increasing the aesthetics of the top cover 3.

[0049] In some improvements of this application, the sieve holes 22 are arranged in an array on the lower peripheral wall and the bottom of the funnel body 2, and the positioning through hole 21 is located above the sieve holes 22. The sieve holes 22 are used to filter out solid impurities. When too many impurities accumulate and block the bottom sieve holes 22, the liquid can still be discharged through the sieve holes 22 on the peripheral wall.

[0050] Reference Figure 3In some improvements of this application, the aperture size of the sieve hole 22 is R mm, and the distance between the center points of adjacent sieve holes 22 is L mm, where 2.5 ≤ R ≤ 3.5 and 4.5 ≤ L ≤ 5.5. This size design is suitable for filtering solids in the surrounding plate and facilitates the discharge of liquid into the drain pipe 1.

[0051] The working and disassembly effects of the clamping filter funnel in the specific embodiments of this application are referenced. Figure 7 and Figure 8 As shown, when the filter funnel is placed into the vent, it is in its initial state. The spring is compressed, providing elastic restoring force to the spring base, forcing the locking part 42 to move downward. The spring plate is compressed and deformed, extending to both sides, so that the locking part 7 and the inner wall of the vent pipe 1 are tightly fitted, achieving the effect of locking the filter funnel. When disassembling, the crew member's fingers pass through the handle part 41 and pull the operating part 4 upward, changing the filter funnel to the separated state. At this time, the spring is compressed and shortened, and the locking part 42 drives the spring plate to retract inward, causing the locking part 7 to separate from the pipe wall of the vent pipe 1, and then fit against the outer wall of the funnel body 2, finally achieving overall force balance and realizing the disassembly of the filter funnel. When it is necessary to clean the inside of the funnel body 2, unscrew the cross-shaped countersunk screw on the top cover 3, separate the handle part 41 of the operating part 4 from the connecting rod 43, and remove the top cover 3.

[0052] In summary, the embodiments of the present invention provide a clamping filter funnel for a discharge port, which has the following advantages:

[0053] 1. Through a clever clamping design, the filter funnel can be clamped to the wall of the discharge pipe 1 in the initial state, solving the potential and practical problems of the ship's discharge pipe 1, and is highly practical;

[0054] 2. The manufacturing process is simple, convenient for construction and installation, and meets both regulatory requirements and shipowner needs while being low in cost;

[0055] 3. The control element 4 and its detachable design facilitate the maintenance and cleaning of the filter funnel, ensuring its stable and reliable operation.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
