Description

Technical Field

[0001] The present invention belongs to the technical field of water pollution control, and particularly relates to a circulating aeration device for lake water pollution control. Background Art

[0002] As a relatively static water body, a lake has limited self-purification ability and is therefore more susceptible to the impact of pollution accumulation. Against this background, aeration technology, as an effective means of water pollution control, is of great importance. Aeration can not only activate the microbial community by increasing the dissolved oxygen content in the water body, promoting the degradation of organic pollutants, but also improve the water quality uniformity by agitating the water body, providing a more suitable living environment for aquatic organisms, thereby comprehensively improving the ecological environment of the lake.

[0003] The existing aeration equipment has a limited coverage area, resulting in a significant increase in the dissolved oxygen concentration near the aeration equipment, while the area far from these devices is difficult to obtain sufficient aeration effect, forming an obvious "aeration blind zone"; in addition, impurities such as leaves and large algae floating on the lake surface are also important factors affecting the aeration efficiency. These impurities are easily aggregated around the aeration equipment, forming a barrier layer, reducing the contact area between air and water, and lowering the oxygen transfer efficiency. In the long run, it will also cause the aeration equipment to be blocked, increasing the maintenance cost and working difficulty. Therefore, we propose a circulating aeration device for lake water pollution control to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a circulating aeration device for lake water pollution control to solve the existing problems.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a circulating aeration device for lake water pollution control, including a bearing plate and an aerator main body. An annular track groove is opened on the upper surface of the bearing plate. The cross-section of the annular track groove is a convex structure.

[0039] Please refer to Figures 1 - 4As shown in the figure, this embodiment is a method for using a circulating aeration device for lake water pollution treatment: When in use, first insert the windward baffle 116 onto the fixed rod 115, and then place the carrier plate 1 and the aerator main body 2 on the lake surface. The solar panel 119 charges the battery, and the battery then provides kinetic energy to the servo motor, the aerator main body 2, and the hydraulic rod 113. When power is supplied to the servo motor, control the servo motor to rotate left and right for reset, driving the transmission gear 104 to rotate reciprocally, thereby driving the transmission ring 102 to rotate. The transmission ring 102 is in transmission engagement with the nozzle seat 103 to drive it to also rotate left and right, causing the air intake head 1032 to swing accordingly. At the same time, the rotating shaft 1041 of the transmission gear 104 drives the eccentric rod 1042 to rotate, thereby intermittently pressing the extrusion rod 111, causing the collection net box 110 to tilt to collect garbage or seaweed-like debris floating on the arc surface. When the collection net box 110 is full, the hydraulic rod 113 can be controlled to contract, exposing the aerator main body 2 and the collection net box 110 above the water surface for cleaning, and then extending to continue using.

[0040] It should be further noted that the components in the present invention are designed appropriately, and sufficient clearance positions are left for each part, and they will not obstruct each other during the movement process.

An inlet water pipe can also be added to the inlet pipe 201, a water pump is set on the inlet water pipe, and electromagnetic valves are set on the inlet water pipe and the inlet pipe 201 near the water pump and the aerator main body 2. Moreover, the suction pipe of the water pump is connected to below the lake surface, so that the device in the present invention can not only perform aeration by the aerator main body 2, but also suck water through the water pump and spray it through the air intake head 1032 for aeration. The two do not occur simultaneously, but they share the mechanical structure provided by the carrier plate 1. When using one of them, the electromagnetic valve of the corresponding pipeline needs to be opened, and the electromagnetic valves on other pipelines need to be closed. When it is necessary to perform aeration by the water pump, at this time, through the linkage design of the annular track groove 101 and the transmission ring 102, the nozzle seat 103 is driven to swing reciprocally, significantly expanding the aeration coverage range, effectively reducing the "aeration blind area", and improving the uniformity of the dissolved oxygen distribution in the lake water body.
