Description

Technical Field

[0001] The invention relates to an aerator for aquaculture, in particular to a floating ball fixing structure of the aerator. Background Art

[0002] The main structure of the aerator for aquaculture includes an impeller that stirs the water surface, a main engine that drives the impeller to rotate, a float that floats the entire aerator on the water surface, and a connecting rod connecting the float and the main engine. Most existing aerators rely on screws to fix the float on the connecting rod. An aerator has at least three floats, each of which is generally fixed to the connecting rod with four screws, and a total of 12 screws need to be installed. These 12 screws need to be tightened one by one by the staff at the breeding site with tools. It takes an average of about 1-2 minutes per screw to install the screws in this part using manual or electric tools, and skilled workers will be faster. According to skilled workers, assuming that it takes 10 minutes to complete the installation of these 12 screws, it will take 10 minutes to install an aerator between the float and the connecting rod. Assuming that a farm has 50 aerators, 600 screws need to be tightened (excluding the installation of other accessories). The installation time for connecting the connecting rod and the float alone is 10 hours, and the installation labor cost is high. Summary of the invention

[0003] The object of the present invention is to provide an aerator with a floating ball that is easy to install, so as to reduce the installation time cost.

[0004] The present invention is implemented as follows: an aerator that is easy to install a float includes an impeller that stirs the water surface, a main engine that drives the impeller to rotate, a float that floats the entire aerator on the water surface, and a connecting rod connected between the float and the main engine. In particular, each float is fixed with a first connecting piece, and each connecting rod is fixed with a second connecting piece corresponding to the first connecting piece. The first connecting piece is slidably connected to the second connecting piece, and the sliding connection constrains the first connecting piece to only slide along the second connecting piece; the first connecting piece or the second connecting piece is provided with a positioning hole, and the second connecting piece or the connecting rod or the first connecting piece is provided with a spring pin corresponding to the positioning hole. The spring pin is composed of a spring and a pin. The pin is automatically inserted into the positioning hole under the action of the spring, thereby locking the first connecting piece from sliding relative to the second connecting piece, thereby fixing the first connecting piece on the second connecting piece, and connecting the float and the connecting rod are connected as one.

[0005] As the best implementation, the sliding connection constrains the first connecting member to slide only along the second connecting member in a translational sliding direction, which is up and down sliding. A plurality of positioning holes are provided along the height direction.

[0006] As the best embodiment, the first connecting member has two parallel slots, and the second connecting member is an end plate fixed to the end of the connecting rod, and the two parallel opposite sides of the end plate are respectively inserted into the slots from the ends of the two slots along the length direction of the slots, and the shapes of the two slots constrain the end plate to only slide horizontally along the length direction of the two slots.

[0007] As the best embodiment, the first connecting member is a first square tube fixed on the float, and the second connecting member is a second square tube fixed to the end of the connecting rod. The first square tube and the second square tube are nested inside and outside, and the second square tube constrains the first square tube to only slide and translate along the length direction of the second square tube.

[0008] As a best embodiment, the spring of the spring pin is a spring leaf, and the pin is fixed on the spring leaf.

[0009] The advantages of the present invention are: 1. There is no need to use screws to connect the float and the connecting rod, which saves both the cost of screws and the time-consuming cost of screw installation, and meets the reliability of the connection and the convenience of quick installation and disassembly without tools; 2. There is no need to use tools such as wrenches, eliminating the trouble of installing screws on site at the farm; 3. It effectively improves work efficiency and can save more than 90% of the on-site installation time at the farm. In the face of a large number of aquaculture farms in the vast agricultural sector, an average of one aerator is installed per acre of fish pond water surface. A large breeding province is estimated to have millions of aerators in stock, saving a huge amount of manpower and material resources for installation and disassembly.

DETAILED DESCRIPTION

[0011] To facilitate understanding of the present invention, the present invention is described more fully below by way of examples. The examples provide embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in the examples.

[0012] It should be noted that the “first” and “second” mentioned in the present invention are only used to distinguish the names and do not represent specific quantities and orders.

[0013] An embodiment of the oxygenator of the present invention is as follows Figure 1 As shown, it includes an impeller 1 for stirring the water surface, a main engine 2 for driving the impeller 1 to rotate, a float 3 for floating the entire aerator on the water surface, and a connecting rod 4 connecting the float 3 and the main engine 2. Figure 1 , Figure 2 , Figure 3 , each float 3 is fixed with a first connecting member 5, and the first connecting member 5 has two parallel slots 6. Specifically, the first connecting member 5 of this embodiment is a sheet metal part, and the two slots 6 are stamped from the sheet metal part, and the sheet metal part is fixed to the top of the float 3 by a clamp 7. The connecting rod 4 is fixed with a second connecting member 8 corresponding to the first connecting member 5. The second connecting member 8 of this embodiment is an end plate fixed to the end of the connecting rod 4. The end plate 8 can be fixed to the end of the connecting rod 4 by welding, screw connection or integral molding with the connecting rod. The two parallel opposite sides of the end plate 8 are respectively inserted into the slot 6 from the ends of the two slots 6 along the length direction of the slot 6. The shape of the two slots 6 constrains the end plate 8 to only slide up and down along the length direction of the two slots 6.

[0014] See also Figure 2 , Figure 3 , Figure 4 , the first connecting member 5 is provided with a positioning hole 9, and correspondingly, the second connecting member 8 is provided with a spring pin corresponding to the positioning hole 9. The spring pin is composed of a spring 10 and a pin 11. The spring 10 is fixed to the second connecting member 8 by riveting or welding, or can also be directly fixed to the end face of the connecting rod 4. As long as the two parallel opposite sides of the end plate 8 are inserted into the slot 6, the pin 11 can be automatically inserted into the positioning hole 9 under the action of the spring 10, thereby locking the sliding of the end plate 8 relative to the first connecting member 5, so that the first connecting member 5 is fixed to the end plate 8, that is, fixed to the second connecting member 8, so that the float 3 and the connecting rod 4 are connected as a whole. This connection process does not require any tools and is convenient and quick. On the contrary, as long as an external force is used to make the pin 11 overcome the elastic force of the spring 10 and withdraw from the positioning hole 9, it can be like Figure 3 As shown, the end plate 8 is slid out of the slot 6 of the first connecting member 5 to separate the float 3 from the connecting rod 4. This disassembly process does not require any tools and is convenient and quick. As the best implementation, the spring 10 of this embodiment is a spring sheet, and the pin 11 is fixed to the spring sheet 10 by riveting or welding.

[0015] As the best implementation, the end plate 8 of this embodiment constrains the first connecting member 5 to slide in the direction of up and down sliding. Figure 3As shown, a plurality of positioning holes 9 are provided along the height direction on the first connecting member 5. The height of the floating ball 3 relative to the connecting rod 4 can be adjusted by inserting the pin 11 into the positioning holes 9 at different heights, which is more convenient to use.

[0016] It should be noted that the positions of the positioning hole 9 and the spring pin can be interchanged. The positioning hole 9 is opened on the second connecting member 8, and a spring pin corresponding to the positioning hole is correspondingly arranged on the first connecting member 5. The positions of the end plate 8 and the two card slots 6 can also be interchanged. Figure 2 The end plate 8 in the embodiment is modified to the float 3 as the first connecting member. Figure 2 The first connecting member 5 having two slots 6 is modified to the end of the connecting rod 4 as the second connecting member.

[0017] Another embodiment of the present invention is Figure 5 As shown. The first connecting member of this embodiment is a first square tube 12 fixed on the float 3, and the second connecting member is a second square tube 13 fixed on the end of the connecting rod 4. The first square tube 12 is sleeved inside the second square tube 13, and the second square tube 13 constrains the first square tube 12 to slide up and down along the length direction of the second square tube 13. See also Figure 5 , Figure 6 , Figure 7 The spring pin of this embodiment is composed of a spring sheet 10 and a pin 11. The pin 11 is fixed to the spring sheet 10 by riveting or welding. The spring sheet 10 is fixed to the second square tube 13 by rivets 14 or welding. The positioning hole 9 corresponding to the pin 11 is opened on the first square tube 12. When the first square tube 12 is as shown in FIG. Figure 5 When the second square tube 13 is inserted, the pin 11 automatically inserts into the positioning hole 9 under the action of the spring sheet 10, thereby locking the first square tube 12 from sliding relative to the second square tube 13, fixing the first square tube 12 and the second square tube 13 together, and connecting the float 3 and the connecting rod 4 as a whole. When the float 3 needs to be removed, the spring sheet 10 is bent by hand to make the pin 11 withdraw from the positioning hole 9, and the first square tube 12 can slide out of the second square tube 13.

[0018] As the best implementation, the second square tube 13 of this embodiment constrains the first square tube 12 to slide in the direction of translation up and down, and a plurality of positioning holes 9 are provided on the first square tube 12 along the height direction. The height of the float 3 relative to the connecting rod 4 can be adjusted by inserting the pin 11 into the positioning holes 9 at different heights.

[0019] It should be noted that the positions of the positioning hole 9 and the spring pin in this embodiment can be interchanged. The positioning hole 9 is opened on the second square tube 13 , and a spring pin corresponding to the positioning hole 9 is correspondingly provided on the first square tube 12 .

[0020] It should be noted that in this embodiment, the second square tube 13 may be sleeved inside the first square tube 12 .

[0021] It should be noted that the first connecting member and the second connecting member of the present invention are not limited to the illustrated embodiment. For example, the second connecting member may be a dovetail groove, and correspondingly, the first connecting member may be a dovetail-shaped slider sleeved in the dovetail groove. The sliding connection of this dovetail groove structure can also constrain the first connecting member to only slide along the second connecting member.

[0022] It should be noted that the sliding direction of the first connecting member of the present invention along the second connecting member is not limited to the up and down sliding in the illustrated embodiment, but can also be horizontal sliding or oblique sliding at a certain inclination angle to the horizontal plane. Figure 1 The length direction of the two card slots 6 or Figure 5 The length direction of the second square tube 13 can be changed to horizontal, the end plate 8 is inserted into the slot 6 in the horizontal direction, or the first square tube 12 is inserted into the second square tube 13 in the horizontal direction; for example, Figure 1 The length direction of the two card slots 6 or Figure 5 The length direction of the second square tube 13 can be changed to an angle of 45 degrees with the horizontal plane. All of the above are optional embodiments of the present invention.

[0023] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
