Description

Technical Field

[0001] This utility model relates to the field of lake water purification technology, specifically to a lake water purification aeration treatment device. Background Technology

[0002] Aeration of lake water is an effective wastewater treatment method. Aeration can increase the dissolved oxygen content in the water, ensuring the normal growth and reproduction of aerobic microorganisms. These microorganisms can decompose the organic matter in the wastewater and convert it into harmless substances, thereby purifying the lake water.

[0003] The utility model with authorization publication number CN217025519U provides a water purification device for aquaculture in an artificial lake in a coal mining subsidence area. By designing a system in which several water aeration components are installed and connected between vertical screws at intervals, the device can achieve all-round aeration treatment of water in the artificial lake formed in the subsidence area, thereby improving the cleanliness of the aquaculture water.

[0004] However, the height of several water aeration components in the aforementioned patent is not adjustable. The water level of the artificial lake is affected by various factors, including rainfall, lakebed leakage, and manual pumping operations. When the water level of the artificial lake drops, the uppermost water aeration component will be above the lake surface. The air sprayed by this component will dissipate into the atmosphere. This air cannot dissolve in the lake water to increase its oxygen content. Since the aerator used in the device consumes electricity when delivering airflow, if the airflow delivered by the aerator cannot be fully utilized, it will result in a waste of electricity. If the airflow to the uppermost water aeration component is stopped because it is above the lake surface, the efficiency of the device in delivering oxygen to the lake water will decrease, causing the oxygen content in the lake water to drop and affecting the purification of the lake water. Utility Model Content

[0005] The purpose of this invention is to provide a lake water purification and aeration treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one of the objectives of this utility model is to provide a lake water purification and aeration treatment device, including a base. Two upright frames are symmetrically fixedly connected to the edge of the upper surface of the base. Several horizontal plates are vertically arrayed on the side of the two upright frames that are close to each other. A reinforcing plate is fixedly connected between the upper ends of the two upright frames. A hollow cylinder is fixedly connected between two horizontal plates at the same height. A connecting hose is fixedly connected near the end of two adjacent hollow cylinders. The connecting hose communicates with the interior of the hollow cylinder. An air inlet pipe is fixedly connected to the top of the uppermost hollow cylinder. The air inlet pipe communicates with the interior of the hollow cylinder. An aeration component is provided on one side of the hollow cylinder. An adjustment mechanism is provided inside the two upright frames. The adjustment mechanism is used to adjust the spacing between the several horizontal plates at equal intervals.

[0007] As a further improvement to this technical solution, the adjusting mechanism includes several vertically arrayed sliders slidably disposed in the upright frame. A cross hinge is provided on the side of the slider near the horizontal plate. Adjacent cross hinges are rotatably connected by a pin. The cross hinge includes a first hinge rod and a second hinge rod. The middle positions of the first hinge rod and the second hinge rod are rotatably connected by a rotating shaft fixed on the slider. One end of the horizontal plate is rotatably disposed on one of the pins. A movable groove is opened on the horizontal plate, and another pin located at the same height is slidably disposed inside the movable groove.

[0008] As a further improvement to this technical solution, the adjusting mechanism also includes a bottom block fixedly installed on the bottom surface inside the frame. A lower shaft is fixedly connected to the side of the bottom block near the horizontal plate. Two lower connecting rods are coaxially rotatably connected to the lower shaft. One end of each of the two lower connecting rods is fixedly connected to one end of the first hinge rod and the second hinge rod located at the bottom.

[0009] As a further improvement to this technical solution, the adjusting mechanism also includes a top block slidably disposed inside the frame. The top block is located above the uppermost slider. An upper shaft is fixedly connected to the side of the top block near the horizontal plate. Two upper connecting rods are coaxially rotatably connected to the upper shaft. One end of the two upper connecting rods is fixedly connected to one end of the first hinge rod and the second hinge rod located at the top, respectively. A threaded rod is rotatably connected to the upper surface of the top block. The upper side wall of the frame and the reinforcing plate are threadedly connected to the threaded rod.

[0010] As a further improvement to this technical solution, the aeration assembly includes several extension tubes that are horizontally arrayed and fixedly connected to one side of the hollow cylinder. The extension tubes and the interior of the hollow cylinder are connected. Several annular nozzles are arranged horizontally on the extension tubes. Each annular nozzle includes two support pipes that are respectively fixedly arranged at the top and bottom of the extension tube. The ends of the two support pipes away from the extension tube are fixedly connected to the same annular pipe. Several air outlets are opened in an annular array on the annular pipe. The support pipes connect the annular pipe and the extension tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This lake water purification and aeration device works by having the operator simultaneously turn two threaded rods when the lake level drops. This reduces the spacing between two sets of vertically arranged horizontal plates, allowing the two uppermost horizontal plates to move the hollow cylinder and aeration components below the lake surface. This ensures that all oxygen emitted from the air outlets dissolves in the lake water, increasing dissolved oxygen levels while preventing air waste and guaranteeing the device's aeration efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-5 As shown, one of the objectives of this embodiment is to provide a lake water purification and aeration treatment device, including a base 1, which can be a square frame structure. Several ground nails are fixedly installed on the lower side of the base 1 near its perimeter. During use, the operator submerges the device in the lake, making the lower surface of the base 1 contact the lake bottom, and inserts the ground nails into the mud and sand at the bottom of the lake to secure the device. Two upright frames 2 are symmetrically fixedly connected to the edge of the upper surface of the base 1. Several horizontal plates 3 are vertically arranged in an array on the side of each upright frame 2 that is close to each other. Hollow cylinders 4 are fixedly connected near the ends of two horizontal plates 3 at the same height. A connecting hose 41 is fixedly connected between adjacent hollow cylinders 4, communicating with the interior of the hollow cylinder 4. An air inlet pipe 42 is fixedly connected to the top of the uppermost hollow cylinder 4, communicating with the interior of the hollow cylinder 4 and connecting to the output port of an air pump placed on the lake shore. An aeration component is provided on one side of the hollow cylinder 4. The structure of the aeration component is detailed below, referring to... Figure 2 and Figure 3The aeration assembly includes several extension tubes 43 horizontally arrayed and fixedly connected to one side of the hollow cylinder 4. The extension tubes 43 and the interior of the hollow cylinder 4 are connected. Several annular nozzles are arranged horizontally on the extension tubes 43. Each annular nozzle includes two support pipes 44 respectively fixedly installed at the top and bottom of the extension tube 43. The ends of the two support pipes 44 away from the extension tube 43 are fixedly connected to the same annular pipe 45. Several air outlets 46 are arranged in annular array on the annular pipe 45. The support pipes 44 connect the annular pipe 45 and the extension tube 43. After the base 1 is fixed to the lake bottom with ground nails, the several annular pipes 45 are all submerged in the lake water. When the air pump pumps air through the air inlet pipe 42 into the uppermost hollow cylinder 43... After entering the cylinder 4, air is diverted through several connecting hoses 41 to several hollow cylinders 4 located below it. The airflow in the hollow cylinders 4 enters several extension cylinders 43. The airflow in the extension cylinders 43 enters several annular pipes 45 through support pipes 44. The airflow in the annular pipes 45 is sprayed into the lake water through several air outlets 46. Because the several annular pipes 45 are distributed at different depths in the lake water, and there are several air outlets 46 distributed in multiple directions, the oxygen in the airflow sprayed from the several air outlets 46 will dissolve in a large area of ​​lake water at different depths, and will dissolve in a large area of ​​lake water along with the natural flow of the lake water, thereby improving the aeration effect of this device on the lake water.

[0027] When the lake water level drops, exposing the upper part of the annular pipe 45 to the air, the air ejected from the air outlet 46 of the upper annular pipe 45 will escape into the atmosphere. Meanwhile, the annular pipe 45 underwater will have reduced gas content entering the lake water due to the obstruction of the lake water. The escaped air cannot dissolve in the lake water to increase its oxygen content, thus wasting resources. To solve this problem, an adjusting mechanism 5 is installed inside both vertical frames 2. The adjusting mechanism 5 is used to adjust the spacing between several horizontal plates 3 at equal intervals. When the lake water level drops, causing the upper horizontal plate 3 and the annular pipe 45 to be higher than the lake surface, the operator uses the adjusting mechanism 5 to reduce the distance between the vertically arranged horizontal plates 3 and to move all the vertically arranged horizontal plates 3 downwards. This causes the two uppermost horizontal plates 3 to move the hollow cylinder 4 and the aeration components between them to below the lake surface. This ensures that the oxygen in the air sprayed from all the air outlets 46 in the device can dissolve in the lake water, increasing the dissolved oxygen content in the lake water while avoiding air waste and ensuring the aeration efficiency of the device.

[0028] The structure of the adjusting mechanism 5 is described in detail below, with reference to... Figure 4 and Figure 5The adjustment mechanism 5 includes several vertically arrayed sliders 51 slidably disposed in the frame 2. A cross hinge is provided on the side of each slider 51 near the horizontal plate 3. Adjacent cross hinges are rotatably connected by pins 54. Each cross hinge includes a first hinge rod 52 and a second hinge rod 53. The middle positions of the first hinge rod 52 and the second hinge rod 53 are rotatably connected by a rotating shaft 511 fixed to the slider 51. One end of the horizontal plate 3 is rotatably disposed on one of the pins 54. A movable groove 31 is provided on the horizontal plate 3. Another pin 54 at the same height is slidably disposed inside the movable groove 31. The adjustment mechanism 5 also includes a bottom block 55 fixedly disposed on the bottom surface inside the frame 2. A lower shaft 551 is fixedly connected to the side of the bottom block 55 near the horizontal plate 3. The upper slider 51 is coaxially rotatably connected to two lower connecting rods 56. One end of each lower connecting rod 56 is fixedly connected to one end of the first hinge rod 52 and the second hinge rod 53 located at the bottom, respectively. The adjusting mechanism 5 also includes a top block 57 slidably disposed inside the vertical frame 2. The top block 57 is located above the uppermost slider 51. An upper shaft rod 571 is fixedly connected to the side of the top block 57 near the horizontal plate 3. Two upper connecting rods 58 are coaxially rotatably connected to the upper shaft rod 571. One end of each upper connecting rod 58 is fixedly connected to one end of the first hinge rod 52 and the second hinge rod 53 located at the top, respectively. A threaded rod 59 is rotatably connected to the upper surface of the top block 57. A reinforcing plate 21 is fixedly connected between the upper ends of the two vertical frames 2. The reinforcing plate 21 makes the two vertical frames 2 less prone to displacement. The device is tilted to enhance its structural strength. The upper sidewall of the frame 2 and the reinforcing plate 21 are threadedly connected to the threaded rod 59. After the base 1 is fixed to the lake bottom with ground nails, the upper ends of the two frames 2 and the reinforcing plate 21 are always higher than the lake surface. When the lake water level drops, the operator drives the work boat close to the device, and then the operator simultaneously turns the two threaded rods 59. Through the threaded connection between the threaded rods 59 and the reinforcing plate 21 and the upper sidewall of the frame 2, the threaded rods 59 move downward along the axis of the threaded rods 59. The moving threaded rods 59 drive the top block 57 to slide downward along the inner wall of the frame 2. The top block 57 drives the first hinge rod 52 and the second hinge rod 53 located at the top to rotate around the rotation axis 511 through the two upper connecting rods 58. Hinges 52 and 53, via pins 54, cause the first hinge 52 and 53 located below them to rotate as well. This causes several cross hinge frames to retract synchronously, so that the first hinge 52 and 53 at the bottom respectively drive the two lower connecting rods 56 to rotate around the lower shaft 551. This causes several cross hinge frames to move the top block 57 closer to the bottom block 55. The two horizontal plates 3 and the hollow cylinder 4 at the same height form a U-shaped structure. The pins 54 on the several cross hinge frames, as they retract as a whole, drive the corresponding horizontal plates 3 to move vertically downward. This shortens the distance between several U-shaped structures, and the several U-shaped structures move downward as a whole. At the same time, the pins 54 at the same height as the pins 54 on the horizontal plates 3 slide along the inner wall of the movable groove 31 on the horizontal plates 3.The pin 54 and the movable groove 31 work together to restrict the rotation of the horizontal plate 3, keeping it horizontal during movement. This causes several U-shaped structures to move their corresponding aeration components downwards, ensuring all aeration components are below the lake surface. This allows oxygen from all air outlets 46 to dissolve in the lake water, increasing dissolved oxygen levels while preventing air waste.
