Abstract
Description
Technical Field
[0001] The invention relates to the technical field of port and waterway aeration, and in particular to an aeration joint with a backwashing function. Background Art
[0002] A port channel is a waterway between the main channel of a sea or inland river and the harbor basin, allowing ships to enter and exit the port. A port channel must be of sufficient width and depth, appropriately oriented, and have relatively stable water flow to ensure safe and convenient access for ships. The layout of a port channel is closely related to the port's location. If a port is built in deep water, low water levels (tidal levels) and depth ensure safe navigation. Navigation marks are simply placed along the most convenient route for ships entering and exiting the port; this is a natural channel. If a port is built in shallow water or the harbor basin is artificially excavated, the natural water depth cannot meet navigational needs, and an artificial channel must be excavated. Due to the flow of water in a port channel, silt accumulates, leading to congestion in the port channel. Port channel aeration devices are primarily used to physically remove silt and restore channel smoothness. However, existing port channel aeration devices, due to direct contact with seawater, often allow marine organisms to clog the aeration holes, causing blockages. Sometimes, backwashing the aeration holes due to the fluctuations of the seawater makes it easier for marine organisms to enter the aeration holes, causing blockages. Summary of the Invention

[0004] The technical solution of the present invention is as follows: an aeration joint with a backwash function, comprising a joint outer shell, one side of the joint outer shell is threadedly connected to the joint base, the side of the joint base away from the joint outer shell is connected to the air pipe joint, a through hole is provided in the center of the joint base, the through hole is provided at one end within the joint outer shell and is provided with a steel ball, the end of the joint base within the joint outer shell is threadedly connected to a clamping bolt, the end of the clamping bolt facing the through hole is fixedly connected to a compression spring, the end of the compression spring away from the compression bolt is fixedly connected to the steel ball, a through hole is provided in the center of the compression bolt, the joint outer shell is connected to an explosion inner core through tolerance fitting, an outer ring compression spring is sleeved on the explosion inner core, and the end of the explosion inner core away from the joint base is connected to an anti-fouling plate through a fixing bolt.
[0005] As a preferred embodiment, the end of the through hole on the joint base that contacts the steel ball is the upper end, and the other end is the lower end, and the diameter of the through hole at the upper end is larger than the diameter of the through hole at the lower end.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0016] Example
[0017] An aeration joint with a backwash function comprises a joint outer shell 1, one side of the joint outer shell 1 is threadedly connected to a joint base 2, the side of the joint base 2 away from the joint outer shell 1 is connected to an air pipe joint, a through hole is provided in the center of the joint base 2, and a steel ball 3 is provided at one end of the through hole located in the joint outer shell 1, and a clamping bolt 5 is threadedly connected to the end of the clamping bolt 5 facing the through hole, and a clamping spring 4 is fixedly connected to the end of the clamping spring 4 away from the clamping bolt 5, and a through hole is provided in the center of the clamping bolt 5, and an explosion core 6 is connected in the joint outer shell 1 through a tolerance fit. An outer ring compression spring 7 is sleeved on the explosive inner core 6, and the end of the explosive inner core 6 away from the joint base 2 is connected to the anti-fouling plate 8 by a fixing bolt 9. When not in use, the compression spring 4 squeezes the steel ball 3 to block the through hole on the joint base 2, and the explosive inner core 6 as a whole is in contact with the joint base 2 due to the elastic force of the outer ring compression spring 7, hiding the explosive hole. When in use, gas is injected from one side of the joint base 2 through the air pressure adjusting device, and the steel ball 3 is pushed by the air pressure to make the gas enter the cavity behind the compression bolt 5, so that the explosive inner core 6 drives the anti-fouling plate 8 to move, stirs up the silt in the port channel, and brings it out of the port through the movement of sea water, so as to achieve the purpose of dredging.
[0018] The end of the through hole on the joint base 2 that contacts the steel ball 3 is the upper end, and the other end is the lower end. The diameter of the through hole at the upper end is larger than the diameter of the through hole at the lower end. By gradually increasing the diameter, the gas enters from the narrow diameter to the larger diameter, further increasing the circulation speed of the gas and pushing the steel ball 3.
[0019] There is a cavity between the joint base 2 and the explosive inner core 6. The through hole on the explosive inner core 6 is connected to the cavity. The cavity can temporarily store gas. When the gas pressure is greater than the elasticity of the outer ring compression spring 7, it can drive the explosive inner core 6 to move, thereby pushing the sludge to turn over.
[0020] A plurality of axially symmetrical holes are provided on the circumference of the upper part of the explosion inner core 6, and the axially symmetrical holes are spaced ninety degrees apart. The axially symmetrical holes are connected to the through holes on the explosion inner core 6. The axially symmetrical holes are non-through holes, which facilitates the uniform distribution of gas pressure on the explosion inner core 6 and drives the explosion inner core 6 to move; the joint outer shell 1 is made of stainless steel, which saves costs and effectively avoids corrosion from seawater.
[0021] Finally, it should be noted that the embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
