Description

Ring aeration frame

technical field

The utility model relates to aquaculture aeration equipment, in particular to an annular aeration frame.

Background technique

With the development of the economy, people's material needs continue to increase. Many aquatic products such as fish, shrimp, crabs, etc., naturally grown products are far from meeting people's growing needs, and artificial breeding is needed to continuously supplement market demand. However, artificially farmed aquatic products, especially high-density artificially farmed fish, shrimp and crabs, are closely related to the oxygen content of the cultured water. The amount of dissolved oxygen in aquaculture water directly affects the food intake, food digestion and absorption rate, growth rate and feed coefficient of the aquaculture object. When the amount of dissolved oxygen is insufficient or too low to meet the needs of aquatic organisms, fish and shrimp not only do not want to eat, they are unresponsive, grow slowly, and even suffocate and die in large numbers. Traditional buoy-type impeller aerators and submersible aerators respectively aerate the aquaculture waters from the shallow water surface or the bottom of the water, and have a certain oxygen-increasing effect, but both have the disadvantages of high energy consumption and low efficiency. The rotation will also hurt the aquatic organisms that are close to it, and the water flow in the aquaculture water area will also produce bottom silt, which will affect the living environment of aquatic organisms. The disadvantage of the existing aeration device with aeration head is that because most of the pipelines are made of iron and the structure is fixed, the production cost is high, and it cannot be automatically adjusted according to the terrain and air pressure, and it cannot be sieved, which greatly Reduced oxygenation efficiency. The prior art, such as the utility model authorized by the announcement number CN 202072548 U, discloses an automatically adjustable movable aeration disk, including an aeration coil, a first plastic flexible chain, a second plastic flexible chain, an outer ring tube and For heavy objects, the plurality of first plastic soft chains are evenly connected radially between the aeration coil and the outer circular tube, and the aeration coil is in the shape of a spiral involute and is connected with each first plastic soft chain , and the bottom of the outer circular tube is connected with heavy objects through several second plastic flexible chains. However, the application of this device in a large water body requires many aeration disks to be arranged in a row, and the cost is still relatively high.

Contents of the invention

The purpose of the utility model is to provide an annular oxygen increasing frame with good oxygen increasing effect, low cost of use, large oxygen increasing cross-section and low equipment quantity required per unit water body in view of the prior art.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: an annular oxygen-increasing frame, including microporous tubes arranged horizontally, wherein: the microporous tubes, the vertical tubes connected to the two ends and the floating frame tubes on the top form an annular structure. The inflatable ring frame; the inflatable ring frame is connected with a float; the floating frame tube is connected with an anti-winding hose capable of supplying air to the microporous tube; the anti-winding hose is provided with an anti-winding device. The float on the floating frame tube provides buoyancy to the whole inflatable ring frame, so that the whole device floats on the water surface. By pulling the inflatable ring frame to move on the circular track, it can meet the oxygenation demand of a large water body with a small number of devices, and can fully stir the water body.

In order to optimize the above technical scheme, the measures taken also include: the microporous tube, the vertical tube connected to the two ends and the floating frame tube at the top form an annular inflatable ring frame; the inflatable ring frame is connected with floats; the floating frame tube is connected with An anti-winding hose that can supply air to the microporous tube; the anti-winding hose is equipped with an anti-winding device. The float on the floating frame tube provides buoyancy to the whole inflatable ring frame, so that the whole device floats on the water surface. By pulling the inflatable ring frame to move on the circular track, it can meet the oxygenation demand of a large water body with a small number of devices, and can fully stir the water body. There is a connecting frame between the anti-winding hose and the floating frame pipe, and resistance strips are arranged symmetrically on both sides of the connecting frame. When using the rope traction method, add resistance strips, and keep the microporous tube basically perpendicular to the direction of movement during exercise, so as to obtain a larger cross-section of oxygenation. A flexible rolling ring is sheathed on the microporous tube. The rolling ring is the effect of friction between the small microporous tube and the bottom of the pool when the microporous tube is relatively close to the bottom of the pool. Both ends of the floating frame tube are provided with limit strips. In the absence of resistance strips, it is preferable to add limit strips to prevent items from being entangled and impacted between multiple parallel inflatable ring frames, and to play a certain protective role. A buckle connection can be selected between the floating frame tube and the float. The elbows at both ends of the microporous tube can be made of PVC material, which is convenient for plugging and sealing.

Because the utility model has adopted the microporous tube and the vertical tube connected at the two ends and the floating frame tube at the top to form an annular inflatable ring frame; the inflatable ring frame is connected with a float; Anti-winding hose for air supply; anti-winding device is provided on the anti-winding hose. The float on the floating frame tube provides buoyancy to the whole inflatable ring frame, so that the whole device floats on the water surface. By pulling the inflatable ring frame to move on the circular track, it can meet the oxygenation demand of a large water body with a small number of devices, and can fully stir the water body. Therefore, the utility model has the advantages of good oxygenation effect, low use cost, large oxygenation cross-section, and low number of equipment required per unit water body.
