Description

Technical Field

[0001] This utility model belongs to the field of aerator technology, specifically a variable frequency direct drive energy-saving aerator. Background Technology

[0002] The variable frequency direct drive energy-saving aerator is a high-efficiency aeration equipment used in aquaculture. It is mainly used to increase the contact area between air and water, and at the same time, it uses negative pressure to draw in air and turn it into bubbles and press them into the water, thereby increasing the oxygen content in the water.

[0003] Variable frequency drive (VFD) adjusts the motor speed by changing the frequency of the power supply. The motor speed is directly proportional to the power supply frequency. Therefore, the VFD can precisely adjust the motor speed according to the actual load requirements, allowing the motor to operate in the high-efficiency range under different working conditions. By directly connecting the motor to the load, traditional intermediate transmission devices such as belts and gears are eliminated, which reduces energy loss during transmission, improves transmission efficiency, and thus achieves energy-saving effects.

[0004] Meanwhile, a fishpond aeration system with application number CN202220965218.0 includes a horizontally arranged frame shell. Two vertically symmetrical L-shaped frames are fixedly connected to the lower ends of the frame shell, and a reciprocating translation mechanism is provided on the frame shell. A vertically arranged electric telescopic rod is fixedly connected to the lower side of the reciprocating translation mechanism, and a rectangular frame is fixedly connected to the lower end of the electric telescopic rod. An aeration mechanism is fixedly connected to the rectangular frame. A control panel is fixedly connected to one side of one of the L-shaped frames, and the reciprocating translation mechanism, the electric telescopic rod, and the aeration mechanism are electrically connected to the control panel.

[0005] However, the following problems were found in the implementation of the relevant technology: since no auxiliary support structure was set, the oxygenation mechanism is prone to shaking when rotating, resulting in a lack of overall stability of the oxygenation mechanism. Over time, this can easily lead to significant wear and tear, thus affecting the service life of the oxygenation mechanism. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a variable frequency direct drive energy-saving aerator with the advantage of good stability during aeration.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a variable frequency direct drive energy-saving aerator, comprising a floating body, wherein an aeration component and a support component are respectively provided on the floating body, six mounting holes are opened on the surface of the floating body, a drive source is connected to the top of the floating body, two support seats are connected to the top of the floating body, and waterproof and wear-resistant rings are rotatably connected to the inner side of each of the two support seats, and four mounting rings are connected to the surface of the floating body.

[0008] The surface of the oxygenation component is connected to the surface of the floating vessel body;

[0009] The surface of the support component is connected to the surface of the floating vessel body.

[0010] Preferably, the oxygenation assembly includes two impeller drive shafts, which are respectively disposed on the power output ends at both ends of the drive source. Two impeller bodies are connected to the surface of each of the two impeller drive shafts, and a number of blades are connected to the surface of each of the four impeller bodies.

[0011] Preferably, the surfaces of the two impeller drive shafts are rotatably connected to the inner sides of the two waterproof and wear-resistant rings, respectively.

[0012] Preferably, the support assembly includes four support rods, all of which are disposed at the top of the floating vessel body. A fixing ring is connected between every two support rods, and a wear-resistant pad is connected to the inner side of each of the two fixing rings.

[0013] Preferably, the surfaces of the two impeller drive shafts are rotatably connected to the inner sides of the two wear-resistant pads, respectively.

[0014] Preferably, both wear-resistant pads are made of silicone.

[0015] Preferably, the four mounting rings are arranged symmetrically in pairs on the left and right sides of the vertical center line of the floating vessel body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a drive source to easily drive the two impeller drive shafts to rotate, which in turn drives the two impeller bodies and several blades to rotate and stir the water to push air into the water, promote water convection and exchange and water surface renewal, thereby further increasing the dissolved oxygen content in the water and achieving the function of water oxygenation and water treatment, which is energy-saving and environmentally friendly.

[0018] 2. Both the waterproof and wear-resistant ring and the wear-resistant pad of this utility model are rotatably connected to the impeller drive shaft. Therefore, the waterproof and wear-resistant ring and the wear-resistant pad provide dual support for the impeller drive shaft, which helps to improve the stability of the impeller drive shaft rotation, that is, improve the stability of the blade rotation and oxygenation, and avoid the situation of shaking and increased wear. In addition, the waterproof and wear-resistant ring and the wear-resistant pad improve the wear resistance of the impeller drive shaft, which helps to extend the service life of the impeller drive shaft and the blades.

[0027] 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.

[0028] like Figures 1 to 4 As shown, this utility model provides a variable frequency direct drive energy-saving aerator, including a floating body 1, an aeration component 2 and a support component 3 respectively provided on the floating body 1, six mounting holes 4 opened on the surface of the floating body 1, a drive source 5 connected to the top of the floating body 1, two support seats 6 connected to the top of the floating body 1, waterproof and wear-resistant rings 7 rotatably connected to the inner side of the two support seats 6, and four mounting rings 8 connected to the surface of the floating body 1.

[0029] The surface of the oxygenation component 2 is connected to the surface of the floating vessel body 1;

[0030] The surface of the support component 3 is connected to the surface of the floating body 1.

[0031] Specifically, the oxygenation component 2 includes two impeller drive shafts 21, which are respectively set on the power output ends at both ends of the drive source 5. Two impeller bodies 22 are connected to the surface of each of the two impeller drive shafts 21, and several blades 23 are connected to the surface of each of the four impeller bodies 22.

[0032] Furthermore, the surfaces of the two impeller drive shafts 21 are rotatably connected to the inner sides of the two waterproof and wear-resistant rings 7, respectively.

[0033] Furthermore, the support assembly 3 includes four support rods 31, all of which are located at the top of the floating body 1. A fixing ring 32 is connected between every two support rods 31, and a wear-resistant pad 33 is connected to the inner side of each fixing ring 32.

[0034] It is worth noting that the surfaces of the two impeller drive shafts 21 are rotatably connected to the inner sides of the two wear-resistant pads 33, respectively.

[0035] It is worth noting that both abrasion pads 33 are made of silicone.

[0036] It is worth mentioning that the four mounting rings 8 are symmetrically arranged in pairs on the left and right sides of the vertical center line of the floating vessel body 1.

[0037] Among them, blade 23 and wear-resistant pad 33 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0038] Working Principle: First, the impeller is installed in the designated position using a special connector, mounting hole 4, and mounting ring 8. Then, the drive source 5 drives the two impeller drive shafts 21 to rotate, thereby driving the two impeller bodies 22 and several blades 23 to rotate and stir the water, introducing air into the water, promoting water convection and exchange, and refreshing the water surface. This further increases the dissolved oxygen content in the water, achieving the function of water oxygenation and treatment. It is energy-saving and environmentally friendly. Furthermore, while the impeller drive shafts 21 rotate, their rotational connection with the waterproof wear-resistant ring 7 and the wear-resistant pad 33 enhances the stability of the impeller drive shaft rotation through the dual support of the waterproof wear-resistant ring 7 and the wear-resistant pad 33, thus improving the stability of the oxygenation process of the blades 23 and preventing... The resulting shaking increases wear, and both the waterproof wear-resistant ring 7 and the wear-resistant pad 33 improve the wear resistance of the impeller drive shaft 21, helping to extend the service life of the impeller drive shaft 21 and the blades 23. It should be emphasized again that this variable frequency direct drive is an existing technology, which mainly adjusts the motor speed by changing the frequency of the motor power supply. The motor speed is directly proportional to the power supply frequency. Therefore, the frequency converter can accurately adjust the motor speed according to the actual load requirements, so that the motor can operate in the high-efficiency range under different working conditions. Directly connecting the motor to the load eliminates the need for traditional intermediate transmission devices such as belts and gears. This reduces energy loss during transmission, improves transmission efficiency, and thus achieves energy saving and helps to save resources.
