Description

Technical Field

[0001] The present application relates to the field of oxygenation devices, and in particular to an easy-to-install digital fishery oxygenation device. Background Art

[0002] Impeller aerators are widely used in aquaculture, such as fish farming, shrimp farming, etc. It can effectively increase the oxygen content of aquaculture water, thereby promoting biological growth and health. In addition, impeller aerators can also inhibit the growth of harmful substances in water bodies and keep the water clean. Impeller aerators can transfer oxygen from the air to the water. When oxygen enters the aerator from the air, some structures of the aerator will disperse the oxygen in the water. In this process, the oxygen will form a layer of bubbles and be transmitted underwater with the flow of water. Since the specific gravity of oxygen is lighter than that of water, the bubbles of oxygen will float to the surface of the water and release, thereby increasing the oxygen content in the water.

[0003] The main structure of the impeller aerator is the impeller and the motor, while the ordinary structure is that the impeller is directly sleeved on the motor shaft, and the motor is sealed by a closed casing. In this way, the sealing degree of the motor casing is not very high, and after long-term use, the impeller is not convenient to disassemble. In addition, the connection between the buoy connecting rod on the outside of the ordinary equipment and the motor casing is fixed with bolts. The bolts are rusted after being soaked in water for a long time, and it is relatively difficult to disassemble. Therefore, we propose an easy-to-install digital fishery oxygenation device.

[0031] like Figure 1-Figure 5As shown, the embodiment of the present application provides an easy-to-install digital fishery oxygenation device, comprising:

[0032] A first housing 1, wherein a transmission shaft 7 is sealed and inserted in the middle of the lower side wall of the first housing 1, an impeller 8 is fixedly sleeved on the lower outer side of the transmission shaft 7, and a plurality of plug-in limit block mechanisms 3 are fixedly connected in a ring array in the middle of the outer side of the first housing 1;

[0033] A second housing 2, wherein the lower portion of the second housing 2 is movably inserted into the upper portion of the inner cavity of the first housing 1, a motor 11 is fixedly disposed inside the second housing 2, a first sealing ring 10 is fixedly sleeved on the lower portion of the outer side of the second housing 2, and a sealing plate 12 is sleeved on the rotating shaft of the motor 11;

[0034] The middle part of the plug-in limit block mechanism 3 is limitedly plugged with the connecting rod 4, and the outer ends of the connecting rod 4 are fixedly connected to the buoy 5;

[0035] The upper left and right sides of the first housing 1 are rotatably connected to the positioning frame 9 via a rotating shaft, and the upper opposite ends of the positioning frame 9 are fixed with bolts 18 through threaded insertion.

[0036] Specifically: the impeller 8 adopts the existing oxygenation impeller on the market. The impeller is a prior art. The impeller-type aerator can transfer oxygen in the air to the water. When oxygen enters the aerator from the air, some structures of the aerator will disperse the oxygen in the water. In this process, the oxygen will form a layer of bubbles and be transmitted underwater along with the flow of water. Since the specific gravity of oxygen is lighter than that of water, the oxygen bubbles will float to the water surface and be released, thereby increasing the oxygen content in the water.

[0037] like Figure 2 and Figure 3 As shown: the lower end of the rotating shaft of the motor 11 is fixedly sleeved with the first transmission block 13, and the upper end of the transmission rotating shaft 7 is fixedly connected to the second transmission block 14. The opposite ends of the first transmission block 13 and the second transmission block 14 are both provided with gear blocks in a ring array, and the opposite gear blocks are plugged and meshed with each other.

[0038] Specifically, the motor 11 adopts an existing motor on the market, which is a prior art. The motor 11 drives the first transmission block 13 to rotate, thereby driving the second transmission block 14, so that the transmission shaft 7 and the impeller 8 rotate.

[0039] like Figure 2 and Figure 3 As shown: the sealing plate 12 is connected to the upper part of the rotating shaft of the motor 11 through a bearing sealing sleeve, and a sealing ring is embedded on the outer side of the lower end of the sealing plate 12. The lower end of the sealing ring is pressed and fitted with a circular ring plate 15, and the outer side of the circular ring plate 15 is fixedly connected to the inner wall of the first shell 1.

[0040] Specifically, the pressed part between the annular plate 15 and the sealing plate 12 forms a sealing part.

[0041] like Figure 2 As shown: a connecting block 16 is symmetrically fixedly connected to the outer side of the first shell 1, and the upper end of the connecting block 16 is rotatably connected to the positioning frame 9.

[0042] Specifically: the positioning frame 9 can be turned around the connected axis.

[0043] like Figure 5 As shown: the plug-in limit block mechanism 3 is composed of a plug-in block 31, a limit rod 32, a limit head 33, a pressure ring 34, a spring 35 and a limit cavity 36. The plug-in block 31 is fixedly connected to the outer side of the first shell 1, and a limit cavity 36 is opened on the inner upper part of the plug-in block 31. The middle part of the plug-in block 31 is movably plugged with the limit rod 32, and the lower end of the limit rod 32 is inserted into the cavity of the middle part of the plug-in connecting rod 4 of the plug-in block 31. The lower part of the outer side of the limit rod 32 is fixedly connected with a pressure ring 34, and the pressure ring 34 is movably arranged in the limit cavity 36. The outer side of the limit rod 32 is sleeved with a spring 35 on the upper side of the pressure ring 34, and the lower end of the limit rod 32 is fixedly connected with the limit head 33.

[0044] Specifically, the spring 35 is always in an extrusion state, that is, it presses the pressing ring 34 downward, thereby applying a downward force to the limiting rod 32 , thereby preventing the limiting head 33 from escaping from the limiting groove 41 .

[0045] like Figure 4 and Figure 5 As shown, the connecting rod 4 is inserted into the end of the plug-in block 31 and a plurality of limit grooves 41 are equidistantly arranged outside the end thereof, and the limit heads 33 are movably inserted into the limit grooves 41 .

[0046] Specifically, the limiting head 33 is inserted into the limiting groove 41 to position the connecting rod 4 .

[0047] like Figure 1 As shown: a through hole 6 is opened through the middle of the buoy 5.

[0048] Specifically, the through hole 6 can be used to insert a rod, so that the rod can be inserted into the pond to locate the position of the float 5, and the through hole 6 can also locate the position of the float 5 through a connecting rope.

[0049] like Figure 2 As shown: a second sealing ring 17 is provided between the lower end of the first sealing ring 10 and the first housing 1 .

[0050] Specifically, the second sealing ring 17 can increase the sealing degree at the compression point between the first sealing ring 10 and the first housing 1 .

[0051] Principle of use: When installing the equipment, the second housing 2 is inserted into the upper side of the first housing 1, and the first transmission block 13 and the second transmission block 14 are meshed and connected with each other. Then, the two positioning frames 9 are turned over, and the upper end of the positioning frame 9 is inserted through the thread through the fixing bolt 18, and the lower end of the fixing bolt 18 squeezes the upper end of the second housing 2. Tighten the fixing bolt 18, so that the first housing 1 and the second housing 2 can be squeezed and fitted with each other, and the squeezing force is applied to the sealing plate 12 and the annular plate 15, the first sealing ring 10 and the first housing. The sealing plate 12 and the annular plate 15 are arranged between the opposite surfaces of the housing 1, thereby increasing the sealing degree between the sealing plate 12 and the annular plate 15, the first sealing ring 10 and the first housing 1, and the sealing plate 12 and the annular plate 15 perform secondary sealing on the lower part of the motor 11. The plug-in portion between the transmission shaft 7 and the first housing 1 is the first seal, which greatly increases the sealing degree of the connection between the second housing 2 and the first housing 1, and can effectively provide waterproof protection for the motor 11. The motor 11 and the impeller 8 can be installed by tightening the fixing bolts 18, so that the oxygen enrichment device is easy to install without having to be tightened and fixed by multiple bolts.

[0052] When disassembling the motor 11, it is only necessary to unscrew the fixing bolt 18, then flip the positioning frame 9, and pull out the second housing 2, so that the disassembly, maintenance or replacement of the motor 11 is more convenient;

[0053] When installing the buoy 5, the limiting rod 32 is manually pulled upward, and then the connecting rod 4 is inserted, and then the limiting rod 32 is lowered, so that the limiting head 33 is inserted into the inside of the limiting groove 41, so that the connecting rod 4 can be positioned and installed. When disassembling, the limiting rod 32 is manually pulled upward and the connecting rod 4 is pulled out, so that the disassembly and installation of the connecting rod 4 is convenient, and the disassembly of the connecting rod 4 will not be difficult due to rust.

[0054] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
