Description

Technical Field

[0001] The present invention belongs to the technical field of aerators, and particularly relates to an energy-saving waterwheel aerator. Background Art

[0002] A waterwheel aerator is a device that increases the dissolved oxygen in water by driving the impeller to rotate through an electric motor. It mainly consists of a driving component, a frame, a floating boat, a waterwheel impeller and other four parts. During operation, with the driving component as the power, the waterwheel impeller is driven to rotate. Part or all of the blades of the waterwheel impeller are immersed in water. During the rotation process, the blades hit the water surface at high speed, stirring up water splashes, further dissolving a large amount of air to form dissolved oxygen, bringing the oxygen into the water, and at the same time generating a strong acting force. On the one hand, the surface water is pressed into the bottom of the pool, and on the other hand, the water is pushed to make the water flow, quickly diffusing the dissolved oxygen. The main deficiencies of the current waterwheel aerators on the market are that the waterwheel impeller is usually an integrally injection-molded part. The mold opening cost of such an integrally injection-molded part is relatively high, and when the waterwheel impeller is damaged, the entire waterwheel impeller needs to be replaced. On the one hand, the replacement cost is relatively high. On the other hand, the waterwheel impeller is sequentially fixed on the power output shaft of the driving component, and the replacement is relatively inconvenient. Summary of the Invention

[0027] An energy-saving waterwheel type aerator includes a drive assembly, a drive rod 1, and a plurality of waterwheel impellers 2. The drive assembly is connected to the drive rod 1, and the waterwheel impellers 2 are installed on the drive rod 1. The drive assembly drives the drive rod 1 to rotate, thereby driving the waterwheel impellers 2 fixed on the drive rod 1 to rotate, so as to facilitate the waterwheel impellers 2 to strike the water surface and increase the dissolved oxygen in the water.

[0029] On the waterwheel main body 3, there are a support plate 3-1 and a clamping groove 3-2. The support plate 3-1 abuts against one side end face of the unit plate 4 to support the unit plate 4, and the clamping groove 3-2 is used for clamping the unit plate 4, and the clamping groove 3-2 is arranged on one side of the support plate 3-1. When the unit plate 4 is installed on the waterwheel main body 3 through the clamping groove 3-2, the unit plate 4 abuts against the support plate 3-1. A connecting plate 3-3 is provided on the support plate 3-1, and the connecting plate 3-3 is inserted into the unit plate 4 to lock and abut the unit plate 4 against the support plate 3-1 through the connecting plate 3-3.

[0030] In this embodiment, during the rotation of the waterwheel main body 3, the end face of the support plate 3-1 that first contacts the water surface is the front part of the support plate 3-1, and the end face that later contacts the water surface is the back of the support plate. A support rib 3-4 is provided on the back of the support plate 3-1, and the support rib 3-4 extends to the front part of the adjacent support plate 3-1, that is, the support rib 3-4 is connected to the adjacent support plate 3-1 respectively to ensure the connection strength between the support plate 3-1 and the waterwheel main body 3.

A connecting rib 3-5 is provided on the front part of the support plate 3-1, and the connecting rib 3-5 is connected to the top of the flat support part 3-4-2, so that a clamping groove 3-2 is formed between the end face of the connecting rib 3-5 close to the waterwheel main body 3 and the outer wall of the waterwheel main body 3, that is, the clamping groove 3-2 is formed on both sides of the flat support part 3-4-2 through the connecting rib 3-5. While increasing the strength of the support plate 3-1 through the flat support part 3-4-2 and the connecting rib 3-5, the clamping groove 3-2 is formed on both sides of the connecting rib 3-5, which is convenient for installing the unit plate 4 on the waterwheel main body 3.

[0032] A connecting block 4-3 is provided at the bottom of the unit plate 4. The connecting block 4-3 is perpendicular to the support plate 3-1.

A second reinforcing rib 4-5 is provided on the side wall of the unit plate 4, and the second reinforcing rib 4-5 is connected to the side wall of the connecting block 4-3. By providing the first reinforcing rib 4-4 and the second reinforcing rib 4-5, it is convenient to improve the connection strength between the plate surface of the unit plate 4 and the connecting block 4-3, thereby improving the service life of the unit plate 4.

[0034] Square reinforcing ribs 3-7 are provided on both sides of the connecting plate 3-3. One side of the square reinforcing rib 3-7 is connected to the support plate 3-1 to prevent the connecting plate 3-3 from twisting relative to the support plate 3-1, improving the connection strength between the connecting plate 3-3 and the support plate 3-1 and increasing the stiffness of the connecting plate 3-3 at the same time. A connection reinforcing rib 4-7 connected to the cross reinforcing rib 4-6 is provided on the back of the connecting block 4-3.

[0035] A through groove 3-6 is provided on the connecting plate 3-3, and at least part of the through groove 3-6 is arranged outside the unit plate 4 to facilitate binding components such as tie straps on the connecting plate 3-3 to prevent the connecting plate 3-3 from sliding out of the slot 4-8.

[0036] In this embodiment, the insertion and installation directions of the card slot 3-2 and the connecting plate 3-3 are both arranged parallel to the side wall direction of the water wheel main body 3, and the front part of the support plate 3-1 forms an obtuse angle with the insertion and installation directions of the card slot 3-2 and the connecting plate 3-3. Preferably, the back of the unit plate 4 and the bottom of the unit plate 4 form an obtuse angle structure to facilitate the abutment of the unit plate 4 against the support plate 3-1. When the water wheel impeller 2 contacts the water surface, the outer end of the unit plate 4 contacts the water surface first, so that the acting force of the water on the unit plate 4 is decomposed into an acting force parallel to the insertion and installation directions of the card slot 3-2 and the connecting plate 3-3 and an acting force perpendicular to the insertion and installation directions of the card slot 3-2 and the connecting plate 3-3, thereby reducing the acting force on the support plate 3-1 and improving the service life of the support plate 3-1.

[0037] A cross reinforcing rib 4-6 is provided on the back of the unit plate 4, and a third reinforcing rib 4-9 is provided between the side wall of the connection reinforcing rib 4-7 and the side wall of the cross reinforcing rib 4-6 to further increase the connection strength between the connecting block 4-3 and the plate surface of the unit plate 4.
