AI Technical Summary
Pressure sensors on ocean buoys are easily damaged by water or moisture, and current technology cannot effectively protect them.
An installation structure for a marine surface buoy barometric pressure sensor was designed, including a first chamber and a second chamber inside a protective cover. The second chamber is connected to the outside world through an internal vent and an air passage. The second chamber has a large volume to isolate the outside world and prevent water from entering the first chamber. The air passage is used to discharge any small amount of water that enters.
This effectively prevents the sensor body from being damaged by water, improves the reliability and lifespan of the sensor, and reduces the probability of damage under harsh sea conditions.

[0027] A marine surface buoy 1 barometric pressure sensor mounting structure, comprising a protective cover and a sensor body 8. The protective cover is arranged at the top of the buoy 1, and the protective cover is provided with a first chamber 4 and a second chamber 6, the first chamber 4 is communicated with the second chamber 6 through an internal vent hole 5, and the second chamber 6 is communicated with the outer wall of the protective cover through an air passage 7. The sensor body 8 is arranged in the first chamber 4.
[0028] In this embodiment, a second chamber 6 is set up to separate the first chamber 4 from the outside. Under normal circumstances, water will not enter the second chamber 6. In severe sea conditions, if waves hit the part of the buoy 1 above the water, water will first enter the second chamber 6. Since the second chamber 6 has a large volume, a small amount of water will not enter the first chamber 4, thereby avoiding water damage to the sensor body 8.
[0029] In this embodiment, as Figure 1 As shown, the protective cover includes a cover body 3 and a base 2. The base 2 is integrally connected to the top of the buoy 1. In this embodiment, the base 2 and the top cover of the buoy 1 are integrally formed by machine tool. The cover body 3 is detachably installed on the base 2. In this embodiment, the sensor body 8 can be easily maintained, inspected, and replaced by removing the cover body 3.
[0030] In this embodiment, the base 2 is ring-shaped, the inner wall of the base 2 is provided with internal threads 21, and the bottom of the inner side of the base 2 is provided with mounting holes 22.
[0031] The cover 3 includes an inner shell 31 and an outer shell 33, with the inner shell 31 disposed inside the outer shell 33. A first chamber 4 is formed inside the inner shell 31, and a second chamber 6 is formed between the inner shell 31 and the outer shell 33.
[0032] The bottom outer side of the inner shell 31 is provided with an external thread 32, and the cover 3 and the base 2 are detachably connected by the engagement of the internal thread 21 and the external thread 32. In addition, the bottom of the first chamber 4 is connected to the interior of the base 2, so that the mounting hole 22 is connected to the interior of the first chamber 4 and the buoy 1.
[0033] The sensor body 8 includes a mounting part 81, a detection part 82, and a communication line 83. The mounting part 81 is threadedly installed in the mounting hole 22. The detection part 82 is located inside the first chamber 4 and is positioned on top of the mounting part 81. The detection part 82 has a vent 83 for connecting to outside air to detect air pressure. The communication line 84 is located inside the buoy 1 and is connected to the bottom of the mounting part 81.
[0034] An internal vent 5 is provided on the inner housing 31, and multiple internal vent 5 are evenly arranged on the upper part of the inner housing 31, so that the internal vent 5 are all located above the detection part 82.
[0035] The bottom of the second chamber 6 is provided with a partition plate 34, the inner side of the partition plate 34 is sealingly and integrally connected with the inner shell 31, the outer side of the partition plate 34 is sealingly and integrally connected with the outer shell 33, and the bottom of the partition plate 34 and the top of the base 2 are clearance-fitted to form a transverse gap 72. A plurality of bottom air holes 71 are uniformly arranged on the partition plate 34, and the bottom air holes 71 are all communicated with the transverse gap 72 and the second cavity. The bottom of the outer shell 33 extends downward to the outer side of the base 2, and the bottom of the outer shell 33 and the outer side wall of the base 2 are clearance-fitted to form a longitudinal gap 73. The longitudinal gap 73, the transverse gap 72 and the plurality of bottom air holes 71 jointly form an air passage 7 communicated with the second cavity and the outside of the protective cover.
[0036] Due to the "Topsy-Turvy" counterweight design of the bottom of the buoy 1, in the case of large waves, the buoy 1 will shake to a certain extent, mainly showing up and down shaking, and finally being in a stable upright state. Except that the sea wave is higher than the water surface part of the buoy 1 in extremely severe sea conditions, the water surface part of the buoy 1 will not contact the seawater. In the normal working condition, the sensor body 8 and the protective cover remain working in the air on the water surface.
[0037] Generally, no water enters the second chamber 6. In severe sea conditions, if the sea wave hits the water surface part of the buoy 1, a small amount of water first enters the second chamber 6. Due to the large space volume of the second chamber 6, a small amount of water will not enter the first chamber 4, thereby avoiding the damage of the sensor body 8 due to water. In addition, the air passage 7 is arranged at the bottom of the second chamber 6, and the water entering the second chamber 6 will be quickly drained from the air passage 7 due to gravity, further reducing the probability of water entering the sensor body 8.
[0038] Suppose that a small amount of water enters the first chamber 4 through the internal air hole 5 in an extreme case, the first chamber 4 also has a large volume, and the air hole 83 of the sensor body 8 is located in the middle of the first chamber 4, and the internal air hole 5 is communicated with the upper part of the first chamber 4. The water just entering the first chamber 4 will not affect the air hole 83 of the sensor body 8, and the water completely entering the first chamber 4 will also not affect the air hole 83 of the sensor body 8, thereby avoiding the water entering the internal components of the air pressure sensor. At this time, the small amount of water entering the first chamber 4 will be quickly volatilized under the action of transpiration.
[0039] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
