Abstract
Description
Marine ventilation system with locking structure
[0001] The present invention relates to a ventilation device for a ship, and more particularly, to a ventilation device for a ship having a locking structure that allows the door of the ventilation device to be easily locked or opened.
[0002]
[0003] The cargo hold formed on a ship is a space for loading cargo, and the trunk for ventilation is a structure for ventilating the cargo loading space.
[0004] These cargo holds have openings to allow air to pass through, and louver ventilators are installed to open and close these openings.
[0005] These vents can be manufactured in various sizes depending on their intended use, and it is necessary to manufacture them in an optimal size considering the number of ventilation cycles required depending on the workability and characteristics of the cargo.
[0006] And since the vent (vent cover) of the aforementioned ventilation hole must be opened and closed as needed, it must be provided so that it can be easily opened and closed.
[0007] In addition, the vents of the ventilation holes are manufactured to be sturdy enough to withstand a certain amount of pressure and are manufactured to the minimum size necessary for the strength and safety of the hull. In particular, the vents used in the exhaust pipes of conventional ships are attached to the wall in an upright position, and rotate forward to open and rotate downward to shield.
[0008] Since the vent is made of metal and is heavy, a lot of force is required for the opening operation, and the rapid rotation during the shielding operation can cause accidents such as getting caught.
[0009] Additionally, when unlocking, if you do not apply force when opening, it may close again, which is inconvenient as you have to unlock it again.
[0010] In particular, a method of engaging a locking shaft by vertically crossing a horizontally fixed catch to close and lock the vent is used. However, since the catch is conventionally formed in the shape of a square bar, when lowering to engage the locking shaft, it often gets caught on the corner of the catch, causing collision problems.
[0011] And because the locking shaft and the catch are in point contact, there was a disadvantage in that they were prone to wear and tear, and the locking shaft swayed left and right, making it difficult to lock or unlock smoothly.
[0012]
[0013] Accordingly, the present invention has been devised to solve the above-described problems, and an object of the present invention is to provide a ventilation device for a ship having a locking structure in which a cross-section of a locking member is circular so as to minimize collision between the locking member and the locking shaft when opening and closing the vent cover.
[0014] Another object of the present invention is to provide a ventilation device for a ship having a locking structure in which a locking shaft is formed into an integral circular bar shape with a circular cross-section.
[0015]
[0016] To achieve the above object, a ship ventilation device having a locking structure according to the present invention comprises: a vent coaming portion having a passage formed therein; a vent cover portion that is hingedly connected to one side of the vent coaming portion by a hinge-joining portion and rotates to open and close the vent coaming portion; a guide portion that has one end connected to the vent coaming portion and the other end connected to the vent cover portion and rotates in response to the opening and closing operation of the vent cover portion; and a manual locking portion provided on one side of the vent cover portion to enable locking and unlocking of the vent cover portion:
[0017] In a ventilation device for a ship including a, the manual locking unit is configured as a locking means that is fixed to the lower end of the vent coaming unit and has a locking shaft that is fixed to the lower end of the vent cover unit and can move up and down, and the locking shaft is fixed to the lower end of the vent cover unit and is capable of locking the vent cover unit by being caught by the locking means, and the locking means may be configured as a pair of support brackets protruding from the lower end surface of the vent coaming unit and a locking piece that is connected across the support bracket and has a circular bar shape.
[0018] At this time, it is preferable that the outer surface of the above-mentioned hook be machined to form a flat, uniform contact surface at the portion that comes into contact with the locking shaft.
[0019] And the locking means comprises a locking box fixed to the lower part of the vent cover part, a load bushing coupled to the upper surface of the locking box, a locking shaft that penetrates the load bushing and the locking box and is guided by the load bushing to move up and down, a shaft plate coupled to the locking shaft inside the locking box, and a support spring that is installed inside the locking box and is provided between the load bushing and the shaft plate to generate elastic force, wherein the locking shaft has an integral circular rod shape, and an upper end is bent to form an outlet that is bent and extends parallel to the upper surface of the locking box, and a lower end is exposed by penetrating the lower part of the locking box to form a catch that is caught on the catch piece.
[0020] In particular, it is preferable that the outer surface of the above-mentioned hook be machined to form a flat, uniform contact surface at the portion that comes into contact with the hook piece.
[0021]
[0022] According to the present invention described above, the following effects are achieved.
[0023] First, since the catch is a circular rod shape, the descending locking shaft slides smoothly without colliding with the catch when locking the vent cover. This reduces damage and wear to the device.
[0024] Second, since the locking shaft is in the shape of a single circular bar, it is easy to manufacture and costs are reduced.
[0025] Third, a uniform contact surface is formed at the outer surface of the catch and the catch hole where they come into contact, so wear is minimal and there is no shaking during operation, allowing for smooth and stable locking.

[0033] The following examples of the present invention are provided to facilitate a better understanding of the present invention and are not intended to limit the scope of the present invention. In other words, the following examples are provided to ensure a complete disclosure of the present invention and to fully inform those skilled in the art of the invention of the scope of the invention. The present invention is defined solely by the scope of the claims.
[0034] The terminology used herein is for the purpose of describing embodiments and is not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise. As used herein, the terms "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components in addition to the components mentioned.
[0035] Additionally, unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with meanings commonly understood by those of ordinary skill in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.
[0036] In addition, when explaining the present invention, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description may be omitted.
[0037] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. Fig. 1 is a side view showing a ventilation device for a ship having a locking structure according to one embodiment of the present invention, and Fig. 2 is a front view of the present invention illustrated in Fig. 1.
[0038] Referring to the drawing, the present invention can be largely implemented as a vent coaming part (100), a vent cover part (200), a guide part (400), and a manual locking part (500).
[0039] First, the above vent coaming part (100) and vent cover part (200) will be described.
[0040] The above vent coaming (100) is installed on the hull and has a passage formed inside. It may usually have a rectangular frame shape.
[0041] And the vent cover part (200) has a shape corresponding to the inside of the vent coaming part (100), is hinge-coupled to one side of the vent coaming part (100) and rotates, and can seal the vent coaming part (100) to prevent fluids inside the vent coaming part (100) from escaping to the outside, or can be opened to allow ventilation.
[0042] At this time, a hinge part (300) is provided between the upper surface of the vent cover part (200) and the upper surface of the vent coaming part (100), so that the vent cover part (200) can be opened and closed by rotating from bottom to top.
[0043] Next, the above guide part (400) will be described.
[0044] The above guide part (400) serves to regulate the rotation stroke of the vent cover part (200) with respect to the vent coaming part (100) within a certain range, and as shown, is a link in which a long guide hole (410) is formed along the length.
[0045] One end of the above guide portion (400) is rotatably hinged to the side of the above vent coaming portion (100).
[0046] And, a hook (420) protruding from the side of the vent cover part (200) is inserted into and fastened to the guide hole (410) to guide the rotation of the vent cover part (200).
[0047] Here, the guide hole (410) has a curvature to be linked to the rotational motion of the catch (420), and the upper part of the guide hole (410) is further extended to one side to form a support jaw, so that when it is connected to the catch (420), the open state of the vent cover part (200) is fixed within a certain angle.
[0048] In addition, the curvature of the guide hole (410) is formed to follow the rotational path of the catch (420) to guide the rotational motion of the catch (420) smoothly and smoothly. In other words, a structure is desirable that can prevent wear or damage by minimizing friction or contact impact between the guide hole (410) and the catch (420) as much as possible even during continuously repeated opening and closing operations.
[0049] Next, the manual locking part (500), which is a core technical feature of the present invention, will be described with reference to FIGS. 3 to 5. FIG. 3 is a cross-sectional view of the engaging member of the present invention illustrated in FIG. 1, FIG. 4 is a side view of the locking shaft of the present invention illustrated in FIG. 1, and FIG. 5 is a cross-sectional view of the engaging member of the locking shaft illustrated in FIG. 4.
[0050] The above manual locking part (500) is configured to manually open and close the vent cover part (200), and can be implemented largely by a catch means (510) and a locking means (520).
[0051] The above-mentioned hooking means (510) is fixed to the lower end of the vent coaming portion (100) and may be composed of a pair of support brackets (511) and a hooking piece (512).
[0052] The above support brackets (511) are provided in pairs spaced apart from each other and protrude forward from the lower portion of the vent coaming portion (100). The support brackets (511) may be formed to protrude from the lower front surface of the vent coaming portion (100), or may be formed in an 'L' shape as illustrated, extending from the lower surface of the vent coaming portion (100) and protruding forward.
[0053] And, a round bar-shaped catch piece (512) is provided between the support brackets (511). That is, both ends of the catch piece (512) can be provided horizontally by being respectively connected to the support brackets (511).
[0054] What is important is that the cross-section of the above-described hook piece (512) is circular. In the past, since the hook piece (512) had a square cross-section, when lowering and locking the locking shaft (523) described later, there was a problem that the end of the locking shaft (523) collided with or got caught on the edge of the hook piece (512), delaying the lowering. However, according to the present invention, as shown in FIG. 3, even if the locking shaft (523) gets caught on the outer periphery of the hook piece (512), it can be naturally and quickly caught on the hook piece (512) by sliding.
[0055] And it is preferable that a uniform contact surface (512a) be formed on one side of the outer circumference of the above-mentioned catch piece (512). The uniform contact surface (512a) is a portion where the outer circumference of the above-mentioned catch piece (512) is made flat by performing a grinding operation on the curved surface. It is preferable that the above-mentioned uniform contact surface (512a) be formed at a portion that comes into contact with the above-mentioned locking shaft (523).
[0056] Therefore, wear can be minimized by making line contact or surface contact with the locking shaft (523).
[0057] Next, the locking means (520) is configured to be fixed to the lower end of the vent cover part (200) and perform locking by hooking the locking shaft (523) to the hook, and may be configured to include a locking box (521), a load bushing (522), a locking shaft (523), a shaft plate (524), and a support spring (525).
[0058] The above locking box (521) is coupled and fixed to the lower part of the vent cover part (200).
[0059] The locking box (521) has a space formed inside so that the locking shaft (523) can pass through and the support spring (525) can be accommodated.
[0060] In addition, a load hole (not shown) is formed on the upper surface of the locking box (521), and the load bushing (522) is coupled to the load hole. The locking shaft (523) passes through the load bushing (522) and enters the locking box (521).
[0061] At this time, the locking shaft (523) is formed in a circular rod shape and passes through the locking box (521) and is supported and guided by the load bushing (522) so that it can be raised and lowered.
[0062] The upper end of the above locking shaft (523) is formed with a bending outlet (523a), and the lower end is formed with a catch (523b).
[0063] In the past, the above-mentioned bending outlet (523a) and the catch (523b) were processed separately and joined by welding, etc., but in the present invention, the above-mentioned bending outlet (523a) is formed by bending the upper end of the above-mentioned locking shaft (523) to extend parallel to the upper surface of the above-mentioned locking box (521), and the catch (523b) is also formed by extending integrally to have a circular cross-section.
[0064] Here, a shaft plate (524) is coupled to the lower portion of the locking shaft (523), and the shaft plate (524) is provided inside the locking box (521).
[0065] The above shaft plate (524) prevents the locking shaft (523) from descending and being detached from the locking box (521).
[0066] That is, the lower side of the shaft plate (524) becomes the catch (523b), and the catch (523b) penetrates the lower side of the locking box (521) and is exposed to the outside, and can be locked by intersecting with the catch piece (512).
[0067] The above-mentioned hook (523b) is formed so that its lower surface is inclined to one side. Specifically, this incline is formed so as to slope upward from the lower side toward the vent cover part (200). Accordingly, the lower end of the hook (523b) is caught by the hook piece (512), thereby allowing the vent cover part (200) to remain closed.
[0068] Meanwhile, a support spring (525) is installed between the shaft plate and the load bushing.
[0069] The above support spring (525) may be a compression coil spring, and the upper part of the support spring (525) is coupled and fixed to the load bushing (522), and the lower part is placed on or coupled to the shaft plate (524) to provide elastic support.
[0070] Accordingly, when the bending outlet (523a) is pushed using a separate long tool, the locking shaft (523) rises, causing the catch (560) to detach from the catch piece (512), thereby opening the vent cover part (200).
[0071] Preferably, a surface finish may be performed on one side of the outer surface of the above-mentioned hook (523b) so that a partially flat uniform contact surface (512a) may be formed.
[0072] The uniform contact surface (512a) of the above-mentioned hook (523b) is in close contact with the uniform contact surface of the above-mentioned hook piece (512), thereby minimizing wear and guiding it so that it does not fluctuate during reciprocating motion.
[0073] Although the present invention has been described with reference to drawings according to embodiments thereof, those skilled in the art will be able to make various applications and modifications within the scope of the present invention based on the above contents.
