Description

Technical Field

[0001] The invention relates to the technical field of river regulation equipment, in particular to a river water oxygenation device. Background Art

[0002] The reduction of dissolved oxygen in river water will seriously affect the self-purification capacity of the water body and the survival of aquatic plants and fish. The main factor is the increase of pollutants flowing into the water body. In the dry season, there is less water from the upstream, and the pollution concentration in the main stream and tributaries increases, causing the oxygen consumption of the water body to increase; when the rainy season comes, the rainwater received by residential areas, roads, life squares, farmland, etc. carries a large amount of pollutants and flows into the river through the rainwater pipe network or directly, causing the oxygen consumption of the water body to increase. At present, the main methods used to solve the problem of low dissolved oxygen in river water are to reduce the amount of pollutants entering the river and to aerate the water to increase oxygen. Aeration devices are installed on the water surface or underwater to force the oxygen in the air into the liquid The purpose of aeration is to obtain sufficient dissolved oxygen; in addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. It is a water treatment method in which water and air are fully in contact to exchange gaseous substances and remove volatile substances in the water, or to allow gas to escape from the water, such as removing the odor of water or harmful gases such as carbon dioxide and hydrogen sulfide; or to dissolve oxygen in the water to increase the dissolved oxygen concentration, so as to remove iron, manganese or promote the degradation of organic matter by aerobic microorganisms.

[0003] However, most of the aeration devices currently available on the market need to be installed on the water surface or underwater when in use, and the power wiring directly enters the water body, posing a safety hazard. The aeration devices may also be damaged by the impact of floating objects on the water surface, affecting navigation, etc. Summary of the invention

[0004] In view of the existing problems, the present invention provides a river water oxygenation device, which can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0007] As a further solution of the present invention: a fixed pulley is installed on the side of the swing cross frame away from the rotating groove, a direction adjustment mechanism is provided on one side of the oxygenation mechanism, a winding roller is provided inside the direction adjustment mechanism, a steel wire rope is sleeved on the outer side of the winding roller, and a positioning rivet is installed on the free end of the steel wire rope.

[0008] As a further solution of the present invention: a hand crank is installed on one end of the winding roller through a movable shaft on the outside of the adjustment mechanism, a one-way ratchet is arranged on the outside of the movable shaft, and a rotating bearing is arranged on one side of the rotating ear plate inside the swinging cross frame.

[0009] As a further solution of the present invention: a transmission sprocket is installed on the outer side of the swing arm at one end of the driving shaft, a driving mechanism is installed on the upper surface of the swing cross frame, and a transmission belt is connected between the driving mechanism and the transmission sprocket.

[0010] As a further solution of the present invention: the end rotating disc and the middle rotating disc are both fixedly connected to the driving rotating shaft, and an elastic rotating shaft is connected between the ratchet pawl and the swinging cross frame.

[0011] As a further solution of the present invention: the pawl is engaged with the limit ratchet gear, the direction-adjusting shaft is movably connected with the swing cross frame, and the retaining cylinder is movably connected with the driving shaft.

[0012] As a further solution of the present invention: the positioning rivet is fixedly connected to the steel wire rope, and the steel wire rope is movably connected to the fixed pulley.

[0013] As a further solution of the present invention: the hand crank handle is fixedly connected to the movable shaft, and the steel wire rope is fixedly connected to the winding roller.

[0014] As a further solution of the present invention: the transmission belt is movably connected to the transmission sprocket, and the driving mechanism is fixedly connected to the swing cross frame.

[0015] As a further solution of the present invention: the rotating ear plate is fixedly connected to the swing arm, the rotating ear plate is fixedly connected to the direction-adjusting shaft, and a water leakage hole is arranged in an array on the outer side of the retaining cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The direction adjustment mechanism and the swing cross frame can control the installation and removal direction of the oxygenation mechanism. The oxygenation mechanism can be placed in the center of the river or on the outside of the river. Therefore, the installation position can be controlled according to the depth and width of the river, thereby achieving a good aeration effect.

[0018] 2. After disconnecting the one-way ratchet limiter at the end of the winding roller, the hand crank handle can be turned to release the steel wire rope wound on the outside of the winding roller, thereby controlling the overall installation inclination of the swing cross frame, so that the installation angle can be adjusted according to the inclination of the overall installation position of the oxygenation mechanism, thereby facilitating the aeration mechanism as a whole to rotate and lift water.

[0019] 3. By applying upward pulling force to the pawl, the pawl is disconnected and limited by the clamping and limiting action of the ratchet gear under the action of the elastic shaft. By applying torque to the knob, the adjustment shaft as a whole cooperates with the guiding action of the rotating bearing to adjust the direction of the swing arm inside the swing cross frame to control the contact between the aeration mechanism and the water inside the river channel, so as to facilitate the aeration treatment of the river channels with different water levels and avoid the danger caused by the aeration mechanism built inside the river channel.

[0020] 4. The retaining cylinder is movably installed on the outside of the driving shaft. Therefore, when the aeration mechanism is controlled in different directions, the retaining cylinder is vertical to the horizontal plane. Water can enter the retaining cylinder from the leakage hole, ensuring that the retaining cylinder can well protect the aeration mechanism and prevent floating objects inside the river from being absorbed by the end disc and the middle disc to affect the normal activity of the aeration mechanism. At the same time, it can also prevent the stones at the bottom of the river from being disturbed as a whole and damaging the aeration mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
