Abstract
Description
Technical Field
[0001] The invention relates to an aerator for aquaculture, and in particular to a fixing structure of a floating ball connecting rod 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 float connecting rod connected between the float and the main engine. Most existing aerators rely on screws to fix the float connecting rod to the main engine. An aerator has at least three float connecting rods, each of which is generally fixed 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 takes 10 minutes to install an aerator between the float connecting rod and the main engine. Assuming that a farm has 50 aerators, 600 screws need to be tightened (excluding the installation of other accessories). The installation time used to connect the float connecting rod to the main engine is 10 hours, and the installation labor cost is relatively high. Summary of the invention
[0003] The object of the present invention is to provide an aerator which is convenient for installing a floating ball connecting rod, 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 connecting rod, includes an impeller that stirs the water surface, a main unit that drives the impeller to rotate, a float that floats the entire aerator on the water surface, and a float connecting rod connected between the float and the main unit. In particular, a first connecting piece is fixed at one end of each float connecting rod, a second connecting piece corresponding to the first connecting piece is fixed to the housing of the main unit, 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; a positioning hole is provided on the first connecting piece or the second connecting piece, and a spring pin corresponding to the positioning hole is provided on the housing of the main unit or the first connecting piece or the second connecting piece. The spring pin is composed of a spring and a pin, and the pin is automatically inserted into the positioning hole under the action of the spring, thereby locking the sliding of the first connecting piece relative to the second connecting piece, thereby fixing the first connecting piece on the housing of the main unit and connecting the float connecting rod to the main unit as a whole.
[0005] As the best embodiment, the first connecting member is an end plate fixed to the end of the float connecting rod, and the second connecting member is a connecting member fixed to the main housing and has two parallel slots. 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. The shapes of the two slots constrain the end plate to only slide horizontally along the length direction of the two slots.
[0006] As a best embodiment, the end plate is a hollow flat tube.
[0007] As the best embodiment, the first connecting member is a first square tube fixed to the end of the float connecting rod, and the second connecting member is a second square tube fixed to the main housing. 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 horizontally along the length direction of the second square tube.
[0008] As the best embodiment, the shell of the host is integrally formed with a blind tube with a single-end opening, the spring of the spring pin is a compression spring, the compression spring is installed in the blind tube, one end of the pin is pressed against the compression spring, and the other end extends from the open end of the blind tube and inserted into the positioning hole, when the pin is retracted into the blind tube due to external force, the pin withdraws from the positioning hole.
[0009] As the best implementation, the pin is connected with a handle, the side wall of the blind tube is provided with a sliding hole, the handle extends from the sliding hole and can slide along the sliding hole, and the handle drives the pin to retract into the blind tube.
[0010] As a best embodiment, the spring of the spring pin is a spring leaf, and the pin is fixed on the spring leaf.
[0011] The advantages of the present invention are: 1. It is not necessary to use screws to connect the main unit and the float connecting rod, which saves both the cost of screws and the time-consuming cost of screw installation, and meets the reliability of the connection while achieving the convenience of quick installation and disassembly without tools; 2. It is not necessary to process screw holes at the connection between the main unit and the float connecting rod, which eliminates the tapping process in the screw holes, and the process is relatively simple, saving manufacturing costs; 3. It effectively improves work efficiency and can save more than 90% of the on-site installation time in 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
[0013] 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.
[0014] 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.
[0015] 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 unit 2 for driving the impeller 1 to rotate, a float 3 for floating the entire aerator on the water surface, and a float connecting rod 4 connected between the float 3 and the main unit 2. The upper part of the main unit 2 is the motor, and the lower part is the gear box. See also Figure 1 , Figure 2 , a first connecting member 5 is fixed at one end of each float connecting rod 4. The first connecting member 5 of this embodiment is an end plate fixed to the end of the float connecting rod. The end plate 5 can be fixed to the end of the float connecting rod 4 by welding, screw connection or integral molding with the float connecting rod. The housing of the host 2 is fixed with a second connecting member corresponding to the first connecting member 5. See also Figure 2 , Figure 3 The second connecting member of this embodiment is two parallel slots 6a and 6b fixed on the housing of the host (because the viewing angle is blocked, Figure 3 Only the lower end surface of the card slot 6a can be seen, and the entire card slot 6a cannot be seen). The two card slots 6a and 6b can be fixed to the host housing by welding or integrally forming with the host housing. The two parallel opposite sides of the end plate 5 are respectively inserted into the card slots 6a and 6b from the lower ends of the two parallel card slots 6a and 6b along the length direction of the card slots. The shape of the two card slots 6a and 6b restricts the end plate 5 to slide up and down along the length direction of the two card slots 6a and 6b.
[0016] See also Figure 2 , Figure 3 The end plate 5 is provided with a positioning hole 7, and the housing of the host 2 is equipped with a spring pin composed of a spring and a pin 8 (the spring is not shown in the figure). As long as the two parallel opposite sides of the end plate 5 are inserted into the slots 6a and 6b, the pin 8 can be automatically inserted into the positioning hole 7 under the action of the spring, thereby locking the end plate 5 relative to the slots 6a and 6b. The sliding of the end plate 5 is fixed to the housing of the host 2, so that the float connecting rod 4 is connected to the host 2 as a whole. This connection process does not require any tools and is convenient and quick.
[0017] See also Figure 2 , Figure 3 The housing of the host 2 is integrally formed with a blind tube 9 with a single end opening. The spring pin adopts a compression spring, which is placed at the bottom of the blind tube 9 (the compression spring is not shown in the figure), and the pin 8 of the spring pin is placed in the blind tube 9. One end of the pin 8 is against the compression spring, and the other end is as shown in FIG. Figure 3 As shown, it extends from the open end of the blind tube 9 and as shown Figure 2 When the pin 8 overcomes the elastic force of the compression spring under the action of external force and retracts into the blind tube 9, the pin 8 withdraws from the positioning hole 7, and the Figure 3 As shown, the end plate 5 is slid out of the slots 6a and 6b to separate the float connecting rod 4 from the main machine 2. This disassembly process does not require any tools and is convenient and quick.
[0018] As the best implementation, see also Figure 2 , Figure 3 The pin 8 is connected with a handle 10, and a sliding hole 11 is provided on the side wall of the blind tube 9. The handle 10 extends from the sliding hole 11 and can slide along the sliding hole 11. When removing the float connecting rod, the handle 10 is manually moved to drive the pin 8 to retract into the blind tube 9. As a preferred embodiment, the handle 10 is a screw connected to the pin 8.
[0019] It should be noted that the positions of the end plate 5 and the two slots 6a, 6b of this embodiment can be interchanged. The end plate 5 is fixed to the main housing as a second connecting member, and the slots 6a, 6b are arranged at the end of the float connecting rod 4 as a first connecting member, or an accessory with slots 6a, 6b is fixed at the end of the float connecting rod 4.
[0020] It should be noted that the end plate 5 of this embodiment is not limited to the shape of the embodiment shown in the figure. Figure 4 The structure shown. Figure 4 The end plate 5 shown is a hollow flat tube, which can be formed by flattening a hollow tube. The end plate of this structure is more solid.
[0021] 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 to the end of the float connecting rod 4, and the second connecting member is a second square tube 13 fixed to the outer shell of the host 2. The first square tube 12 is sleeved outside the second square tube 13. 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 7The spring pin of this embodiment is composed of a spring sheet 14 and a pin 8 fixed to the spring sheet 14. One end of the spring sheet 14 is fixed to the first square tube 12 by a rivet 15 or welding. A positioning hole 7 corresponding to the pin 8 is provided on the second square tube 13. Figure 5 When the first square tube 12 is put on the second square tube 13, the pin 8 is automatically inserted into the positioning hole 7 under the action of the spring sheet 14, thereby locking the first square tube 12 from sliding relative to the second square tube 13, thereby fixing the first square tube 12 on the housing of the host 2, so that the float connecting rod 4 is connected to the host 2 as a whole. When the float connecting rod 4 needs to be disassembled, the spring sheet 14 is bent by hand to make the pin 8 withdraw from the positioning hole 7, and then the first square tube 12 can be slid out of the second square tube 13.
[0022] It should be noted that the positions of the positioning hole 7 and the spring pin in this embodiment can be interchanged. The positioning hole 7 is opened on the first square tube 12 , and a spring pin corresponding to the positioning hole 7 is correspondingly provided on the second square tube 13 .
[0023] It should be noted that in this embodiment, the first square tube 12 may be sleeved inside the second square tube 13 .
[0024] 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.
[0025] 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 slots 6a and 6b or Figure 5 The length direction of the second square tube 13 can be changed to horizontal, the end plate 5 is inserted into the slot in the horizontal direction, or the first square tube 12 is sleeved on the second square tube 13 in the horizontal direction; for example, Figure 1 The length direction of the two slots 6a and 6b or Figure 5 The length direction of the second square tube 13 is changed to be inclined at 45 degrees to the horizontal plane. All of the above are optional embodiments of the present invention.
[0026] 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.
