[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0032] Float type ventilation device embodiment:
[0033] See also Figures 1 to 5 The float type ventilation device 10 provided in this embodiment includes a box body 1, a mounting frame 2 and a float ball 3, and the box body 1 matches the shape of the ventilation pipe used to accommodate it.
[0034] In this embodiment, the box body 1 is trapezoidal in shape as a whole, and includes a bottom plate 11, a top plate 12, and four side walls 13, which enclose a closed chamber 14. The bottom plate 11 and the top plate 12 are respectively arranged on the upper and lower sides of the chamber 14. The number of the side walls 13 can be set to multiple, and this embodiment takes four as an example, and the four side walls 13 are connected end to end; in other implementations, the number of the side wall 13 is also set to one, and the side wall 13 is sleeve-shaped.
[0035] In this embodiment, the four side walls 13 and the top plate 12 are integrally formed, and four ear plates 131 are provided at the lower part of the side wall 13. The ear plates 131 protrude from the inner wall of the side wall 13, and mounting holes are provided through the ear plates 131. The bottom plate 11 is detachably connected to the ear plates 131 by screws, and the screws pass through the bottom plate 11 and are connected to the mounting holes.
[0036] The bottom plate 11 is provided with a first ventilation hole 111 . The diameter of the first ventilation hole 111 is relatively small. The number of the first ventilation holes 111 is preferably multiple. The multiple first ventilation holes 111 are arranged vertically and horizontally, which can not only perform ventilation function but also prevent debris from entering the chamber 14 .
[0037] The top plate 12 is provided with a second ventilation hole 121 , and the diameter of the second ventilation hole 121 is greater than the diameter of the first ventilation hole 111 .
[0038] The mounting frame 2 is disposed in the chamber 14, and the mounting frame 2 includes a mounting ring 21 and a supporting foot 22. The mounting ring 21 is disposed in the middle of the chamber 14, and the mounting ring 21 is disposed corresponding to the second ventilation hole 121. The supporting foot 22 is used to support the mounting ring 21, so that the mounting ring 21 is disposed in the middle of the chamber 14.
[0039] The float 3 is movably arranged in the mounting ring 21. The diameter of the float 3 is slightly larger than the inner diameter of the mounting ring 21. A ventilation channel is formed between the outer wall of the float 3 and the side wall 13. The two ends of the ventilation channel are respectively connected with the first ventilation hole 111 and the second ventilation hole 121. Air can enter from the first ventilation hole 111, pass through the ventilation channel, and then be discharged from the second ventilation hole 121. The vertical distance between the mounting ring 21 and the bottom plate 11 is greater than or equal to the radius of the float 3. Since the diameter of the float 3 is slightly larger than the inner diameter of the mounting ring 21, when the float 3 is placed in the mounting ring 21, the center of the float 3 is located above the center of the mounting ring 21, and there is a preset distance between the bottom of the float 3 and the bottom plate 11, that is, the bottom of the float 3 does not contact the bottom plate 11, which is convenient for opening the first ventilation hole 111 on the entire surface of the bottom plate 11, and avoiding the float 3 blocking the first ventilation hole 111, which is conducive to ensuring sufficient air intake.
[0040] Since the float 3 is movably arranged on the mounting ring 21, when the float 3 is affected by an external force, which may be buoyancy or the impact force of water flow, the float 3 can move toward the second ventilation hole 121; the diameter of the float 3 is larger than the diameter of the second ventilation hole 121, and the float 3 is sufficient to block the second ventilation hole 121 to automatically close the ventilation channel to prevent water from entering. The float 3 is a hollow ball with a certain weight, preferably a 316 stainless steel hollow ball.
[0041] In this embodiment, the number of the supporting feet 22 is set to three, and the three supporting feet 22 are evenly arranged along the circumferential direction of the mounting ring 21. In this embodiment, the supporting feet 22 extend along the axial direction of the mounting ring 21, and the two ends of the supporting feet 22 are respectively connected to the mounting ring 21 and the bottom plate 11. In other embodiments, the supporting feet 22 extend along the radial direction of the mounting ring 21, and the two ends of the supporting feet 22 are respectively connected to the mounting ring 21 and the side wall 13, and a gap is reserved between two adjacent supporting feet 22 for airflow to pass through.
[0042] In order to guide the float 3 to automatically move toward the second ventilation hole 121 , at least one side wall 13 of the box body 1 extends inwardly from an end close to the bottom plate 11 to an end close to the top plate 12 .
[0043] In order to improve the sealing performance of the float 3 blocking the second ventilation hole 121, a sealing ring 4 is provided in the second ventilation hole 121, and the float 3 is sealed and connected to the second ventilation hole 121 through the sealing ring 4. Figure 5 As shown, the sealing ring 4 includes a connecting wall 41 and two flat walls 42. The two flat walls 42 are relatively connected to the two ends of the connecting wall 41. An outwardly opening slot is formed between the connecting wall 41 and the two flat walls 42, and the slot is engaged with the hole wall of the second ventilation hole 121.
[0044] In order to increase the ventilation volume, more than two chambers 14 are provided in the box body 1, and the multiple chambers 14 are arranged in a vertical ventilation direction, and two adjacent chambers 14 are separated by a partition. In this embodiment, two chambers 14 are taken as an example, and each chamber 14 is provided with a second ventilation hole 121, a mounting ring 21, a floating ball 3 and a plurality of first ventilation holes 111, and the second ventilation holes 121, the mounting ring 21 and the floating ball 3 are all arranged in a one-to-one correspondence.
[0045] Ventilation system example:
[0046] See also Figure 6 and Figure 7 , and combined with Figure 1The ventilation system provided in this embodiment includes a ventilation pipe and the float type ventilation device 10 of the above embodiment, and the float type ventilation device 10 is arranged in the air inlet end of the ventilation pipe. The ventilation pipe can be a mushroom-shaped ventilation pipe and a gooseneck type ventilation pipe 20. The present embodiment takes the gooseneck type ventilation pipe 20 as an example. The connecting end of the gooseneck type ventilation pipe 20 is fixedly connected to the main deck 30, the middle part of the gooseneck type ventilation pipe 20 extends upward, and the air inlet end of the gooseneck type ventilation pipe 20 is bent downward. The float type ventilation device 10 is fixedly connected to the air inlet end of the gooseneck type ventilation pipe 20 and is arranged close to the air inlet of the gooseneck type ventilation pipe 20, that is, the float type ventilation device 10 can be hidden in the gooseneck type ventilation pipe 20, which is both beautiful and can play a ventilation and waterproof function. The shape of the float ventilation device 10 matches the shape of the gooseneck ventilation duct 20. The float ventilation device 10 is sealed to the inner wall of the gooseneck ventilation duct 20 by sealing glass glue on all sides, so that the airflow can only enter the gooseneck ventilation duct 20 through the float ventilation device 10.
[0047] In normal state, the float 3 is located in the mounting ring 21, and the ventilation channel is connected to realize the ventilation function; when encountering strong winds and waves, when the ship tilts to the water entry point, some water will enter the box 1. At this time, the float 3 will automatically block the second ventilation hole 121 under the impact of the water flow and the buoyancy of the water on the float 3, so as to prevent the water flow from entering the gooseneck ventilation pipe 20 from the second ventilation hole 121. When the ship slightly recovers its normal posture, the float 3 returns to the mounting ring 21 under its own gravity, and the ventilation channel is automatically opened to ensure good ventilation in the cabin.
[0048] A sealing cover 201 is hinged at the air inlet of the gooseneck ventilation duct 20. When ventilation is required, the sealing cover 201 is opened; when ventilation is not required, the sealing cover 201 can be closed.
[0049] In summary, the utility model provides a mounting ring for mounting a float, so that in the ventilation state, the bottom of the float can be separated from the bottom plate, the first ventilation hole can be set at any position of the bottom plate, and the float can be prevented from blocking the first ventilation hole, which is conducive to ensuring a larger ventilation volume; by arranging the float to be able to move toward the second ventilation hole, when the ship tilts to the water entry point, after water enters the box, under the action of the buoyancy and impact force of the water, the float automatically floats up and blocks the second ventilation hole, so as to close the ventilation channel and prevent water from entering the cabin.
[0050] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
