DETAILED DESCRIPTION

[0039] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0040] Please refer to Figures 1-4 In the embodiments of the present application, the adjustable aeration and oxygenation device for river water ecological management comprises a river oxygenation mechanism 100, a cruising mechanism 200, an oxygen supply mechanism 300 and a mixing unit 350. The river oxygenation mechanism 100 comprises a baffle 110, and a square groove 111 is formed in the baffle 110 near the center position. The cruising mechanism 200 is fixed to the top wall of the baffle 110 and can drive the river oxygenation mechanism 100 to move in the specified area. The oxygen supply mechanism 300 is fixed to the baffle 110 and can cooperate with the cruising mechanism 200 to oxygenate the specified water area. The mixing unit 350 is detachably connected to the oxygen supply mechanism 300 and can mix water and oxygen. The floating plate 120 is fixed to the bottom wall of the baffle 110. The cruising mechanism 200 comprises the following parts: two limiting seats 210 fixedly connected to the top wall of the baffle 110 at both ends, a V-shaped frame 211 fixed between the two limiting seats 210, a roller 220 rotating between the outer walls of the two V-shaped frames 211, a first motor 221 fixed to the outer wall of one of the V-shaped frames 211, a rotating shaft of the first motor 221 being fixedly connected to the roller 220, a U-shaped frame 212 fixed between the outer walls of the two V-shaped frames 211, and a plurality of rubber blocks 223 fixedly connected to the outer wall of the roller 220 at equal angles. The roller 220 is driven by the first motor 221 to rotate along the traction rope, so that the river oxygenation mechanism 100 can reciprocate in the specified area.

[0041] The oxygen supply mechanism 300 comprises the following parts: a second motor 310 fixedly connected to the top wall of the baffle 110, a rotating shaft of the second motor 310 being fixedly connected to a spur gear 311, a circular shell one 320 rotating between the baffle 110 and the floating plate 120, a gear ring 321 fixedly connected to the outer wall of the circular shell one 320, the gear ring 321 being in meshing transmission with the spur gear 311, a circular tube one 340 detachably connected to one end of the circular shell one 320, a dust cover 330 fixedly connected to the top wall of the baffle 110, and a fan 331 fixedly connected in the dust cover 330. The fan 331 sends the gas into the circular tube one 340, and the oxygen is sprayed out through the microporous aeration nozzle 353 on the mixing unit 350. The second motor 310 drives the circular shell one 320 to rotate, and drives the mixing unit 350 to rotate, so that the sprayed oxygen is fully mixed with water.

[0042] The mixing unit 350 comprises the following parts: a circular shell two 351 which is detachably connected with one end of the circular pipe one 340, four circular pipes two 352 which are fixedly connected with the outer wall of the circular shell two 351 at equal angles, a plurality of micro-porous aeration nozzles 353 which are fixedly arranged on the outer wall of the circular pipe two 352 at equal angles, and a baffle 354 which is fixedly arranged on the outer wall of the circular pipe two 352 at the side of the micro-porous aeration nozzle 353, and a plurality of round holes 355 are arranged at equal intervals on the outer wall of the baffle 354. The baffle 354 and the round holes 355 on the mixing unit 350 play a role in blocking the water bubbles, slowing down their rising speed and making the path tortuous, increasing the oxygen dissolving time, and the round holes 355 can decompose larger water bubbles into smaller ones.

[0043] Specifically, when working, the floating plate 120 is fixed to the bottom wall of the partition plate 110, so that the river oxygenation mechanism 100 can float on the water surface. When oxygenation is needed in a specified area, the traction rope is passed through one end of the limiting seat 210 and located between the V-shaped frame 211 and the U-shaped frame 212. The roller 220 is driven to rotate along the traction rope by the first motor 221. Since the outer wall of the roller 220 is provided with rubber blocks 223 at equal angles, the elasticity of the rubber blocks 223 makes them tightly adhere to the traction rope to prevent sliding, thereby driving the river oxygenation mechanism 100 to move back and forth along the track of the traction rope to oxygenate the water in the area. The oxygen supply mechanism 300 cooperates with the cruising mechanism 200 to work. The fan 331 drives the gas to enter the mixing unit 350 from the inside of the circular pipe one 340. The circular pipe one 340 is detachably connected with one end of the circular shell one 320. The number of the circular pipe one 340 can be increased according to the oxygenation depth or demand, and the position of the mixing unit 350 under water can be adjusted by limiting with bolts and arranging sealing elements at both ends of the circular pipe one 340, so as to adjust the oxygenation depth of the river oxygenation mechanism 100. After the gas enters the inside of the circular pipe two 352, it is sprayed from the micro-porous aeration nozzle 353. At the same time, the baffle 354 is fixed to the outer wall of the circular pipe two 352 at the side of the micro-porous aeration nozzle 353, and a plurality of round holes 355 are arranged on the baffle 354. The second motor 310 drives the spur gear 311 to rotate, drives the gear ring 321 to rotate, drives the circular shell one 320 to rotate, and further drives the detachably connected mixing unit 350 to rotate. In the process of rotation, the oxygen sprayed from the micro-porous aeration nozzle 353 forms water bubbles. The water bubbles are blocked by the baffle 354, the rising path becomes tortuous and the speed slows down, the contact time of the water bubbles with the water body is increased, the oxygen dissolving efficiency is improved, and the larger water bubbles can be decomposed by the round holes 355, further promoting the mixing of water and oxygen, and realizing efficient oxygenation of the specified water area.

[0044] Embodiment one

[0045] As Figure 2As shown, in this embodiment, the cruise mechanism 200 includes the following parts: two limit seats 210, which are fixedly connected to both ends of the top wall of the partition 110 respectively; a set of V-shaped frames 211, which are fixed between the two limit seats 210; a roller 220, which rotates between the outer walls of the two V-shaped frames 211; a first motor 221, which is fixed on the outer wall of one of the V-shaped frames 211, and the shaft of the first motor 221 is fixedly connected to the roller 220; a U-shaped frame 212, which is fixed between the outer walls of the two V-shaped frames 211; and several rubber blocks 223, which are fixed at equal angles to the outer wall of the roller 220.

[0046] In this embodiment, the roller 220 is driven by motor 221 to rotate along the traction rope, enabling the river oxygenation mechanism 100 to reciprocate within a designated area. Compared with the traditional fixed-position float-type aeration and oxygenation device, it is no longer limited to aeration at a fixed position. The aeration position can be flexibly adjusted according to the changes in oxygen demand at different locations in the river, solving the problem of poor adaptability of existing devices. Several rubber blocks 223 are fixed at equal angles to the outer wall of the roller 220. Their elasticity allows it to adhere tightly to the traction rope, preventing the roller 220 from sliding on the traction rope. During the movement of the device, the stability of the movement is ensured, ensuring the stable operation of the oxygenation work.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the oxygen delivery mechanism 300 includes the following parts: a second motor 310, which is fixedly connected to the top wall of the partition 110, and a spur gear 311 is fixedly connected to the shaft of the second motor 310; a circular shell 320, which rotates between the partition 110 and the float 120, and a gear ring 321 is fixedly connected to the outer wall of the circular shell 320, which meshes with the spur gear 311 for transmission; a circular tube 340, which is detachable from one end of the circular shell 320; and a dust cover 330, which is fixedly connected to the top wall of the partition 110, and a fan 331 is fixedly connected inside the dust cover 330.

[0048] In practice, the gas is sent into the circular pipe 340 by the blower 331, and then sprayed out through the microporous aeration nozzle 353 on the mixing unit 350. The second motor 310 drives the circular shell 320 to rotate, which in turn drives the mixing unit 350 to rotate, so that the sprayed oxygen and water are fully mixed. Compared with the traditional aeration head that directly sprays air, this method expands the diffusion range of oxygen in the water and improves the utilization efficiency of oxygen.

[0049] Example 2

[0050] like Figure 4As shown, in the embodiment, the mixing unit 350 comprises the following parts: a round shell two 351, which is detachably connected with one end of the round pipe one 340, and four round pipes two 352 are fixedly connected with the outer wall of the round shell two 351 at equal angles, a plurality of micro-porous aeration nozzles 353 are arranged and fixed on the outer wall of the round pipe two 352 at equal angles, and a baffle 354 is fixed on the outer wall of the round pipe two 352 at the side of the micro-porous aeration nozzle 353, and a plurality of round holes 355 are arranged at equal intervals on the outer wall of the baffle 354.

[0051] In the specific implementation, the baffle 354 and the round holes 355 on the mixing unit 350 play a role, the baffle 354 blocks the water bubbles, slows down the rising speed and makes the path tortuous, increases the oxygen dissolving time, the round holes 355 decompose the larger water bubbles into small water bubbles, increase the contact area of oxygen and water, further improve the oxygen dissolving efficiency, and improve the oxygen increasing effect of the whole device.

[0052] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0053] In addition, it should be understood that although the present application is described in the specification in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can be properly combined to form other embodiments that those skilled in the art can understand.
