detailed description

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

A kind of vertical floating float type automatic aeration and oxygenation device, specifically as shown in Figure 1, includes an inflator 100, a float 200 and a piston 300, the bottom periphery of the inflator 100 is provided with a detachable bottom cover 101, the The outer periphery of the bottom of the inflator 100 is threadedly connected to the bottom cover 101, and a cover hole is provided on the bottom cover 101. The piston 300 includes a piston head and a piston rod, and the piston head and the inner wall of the inflator 100 In close contact, one end of the piston rod is affixed to the piston head, the other end passes through the cover hole, and is fixedly connected to the float 200, and the top of the inflator 100 is respectively provided with a one-way air inlet hole Valve 102 and air outlet one-way valve 103, the air inlet one-way valve 102 is connected with a section of air intake pipe 400, the air outlet one-way valve 103 is connected with an air outlet pipe 500, the air inlet pipe 400 and the air outlet pipe 500 A detachable filter screen 600 is provided respectively, and at least two telescopic support rods 104 are provided on the outer wall of the inflatable cylinder 100 .

Wherein, the bottom cover 101 is provided with the piston 300 in a specific manner as follows: the bottom cover 101 is provided with a cover hole, the piston 300 can pass through the cover hole, and can move up and down in the inflator 100 .

Preferably, the structure of the telescopic support rod 104 is subject to the purpose of being able to achieve the telescopic purpose, and it may be formed by screwing several threaded rods whose diameters increase sequentially and which are sequentially socketed.

Preferably, the number of the telescopic support rods 104 is two, three or four, wherein the number of the telescopic support rods 104 is three, and the three telescopic support rods 104 are evenly distributed around the outer circumference of the inflatable cylinder 100 and are stable. Sex is the best.

When the vertical float type automatic aeration and oxygenation device is used, it is fixed in the water through the telescopic support rod 104, the inflator 100 is located above the water surface, and the float 200 is located on the water surface. When the wave surface rises, under the action of buoyancy, the float 200 Float up, and at the same time drive the piston 300 connected to the float 200 to rise, so that the gas in the inflator 100 is squeezed and discharged through the air outlet check valve 103, and then discharged into the water through the air outlet pipe 500. At this time, the air inlet check valve 102 Close; when the wave surface descends, the float 200 descends, driving the piston 300 connected with the float 200 to descend at the same time, at this moment, the gas is inhaled through the air inlet check valve 102, and the air outlet check valve 103 is closed now. Thus, the purpose of automatically aerating and increasing oxygen in water is realized. The bottom cover 101 can prevent the piston 300 from completely falling out of the inflator 100 caused by the sudden drop of the water level. Since the bottom cover 101 is detachable, it is also convenient to clean the inflator 100 .

Before the device is in operation, by adjusting the length of the telescopic support rod 104, the purpose of adjusting the height of the device according to the actual water surface height can be realized, which increases the flexibility of the device.

When the device is in operation, lubricating oil can be added between the piston 300 and the inflator 100 to reduce friction and air leakage. At the same time, since the inflator 100 is above the water surface, on the one hand, the infiltration of water into the inflator 100 is avoided, resulting in the phenomenon that the device cannot be used; lubricating effect.

By setting the detachable filter screen 600 in the air inlet pipe 400 and the air outlet pipe 500 , it can play a role in filtering impurities and avoid some tiny particles from clogging the air inlet check valve 102 and the air outlet check valve 103 .

Preferably, the air inlet one-way valve 102 and the air inlet pipe 400 are sealed by a sealing ring, and the air outlet one-way valve 103 and the air outlet pipe 500 are also sealed by a sealing ring, thereby increasing The airtightness between the one-way valve 102 of the air inlet hole and the air inlet pipe 400 and between the one-way valve 103 of the air outlet hole and the air outlet pipe 500 makes the device not easy to leak.

Preferably, a hook is fixedly connected to the end of the telescopic support rod 104 away from the outer wall of the inflatable cylinder 100 , which prevents the problem of poor stability of common brackets in water. If the bottom of the water is a sandy soil structure, the telescopic support rod 104 can be inserted in the sand together with the crotch, and then the device can be fixed; if the bottom of the water is of a harder quality, a fixing ring can be set at the bottom of the water in advance, and then the crotch is hooked on the fixed On the ring, the device can be fixed.

The above disclosures are only specific embodiments of the present utility model, but the present utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the present utility model.
