In other embodiments, the number of the spraying structures 100 is not limited to 4, such as 6 or 8, and in the case that the span of the net cage 200 is small, the swing ranges of the adjacent 2 spraying structures 100 may intersect and overlap to cover more spraying ranges in a relatively dense arrangement.
Referring to fig. 4 and 5, the spraying structure 100 includes a rotary cylinder 11, an elbow 12, an outer cylinder 13, an outlet flange 14, an inlet flange 15, a base 16, a driving motor 17, a limit switch 18 and a limit stopper 19.
The inside of the rotary cylinder 11 is hollow and vertically disposed. The rotary drum 11 is rotatable about its own axis by the drive motor 17. As shown in fig. 5, the rotary cylinder 11 has a T-shaped cross section. The upper end edge of the rotary cylinder 11 is circumferentially protruded to form a flange 111, the upper surface of the flange 111 is a flange surface, and the flange surface and the outlet flange 14 are connected by a hexagon head bolt 31, a gasket and the like in a flange sealing manner. The lower end of the rotary drum 11 is provided with an inlet flange 15, and is connected with the feeding pipe 300 through the inlet flange 15.
The elbow 12 is arcuate. The elbow 12 extends into the through hole of the outlet flange 14 for welding and fixing. The elbow 12 is communicated with the rotary cylinder 11; bait and air are ejected from the bent pipe 12 along the central channel connected with the bait and the air; the bent pipe 12 swings back and forth along with the rotation of the rotary cylinder 11, so that large-area bait spraying is realized. It will be appreciated that the upper end opening of the elbow 12 remote from the rotary cylinder 11 is the discharge end 102.
Referring to fig. 6, the outer cylinder 13 is a hollow cylinder. The cross section of the outer cylinder body 13 is I-shaped. The outer cylinder body 13 is sleeved on the periphery of the rotating cylinder 11, the upper end of the outer cylinder body 13 is lower than the upper end of the rotating cylinder 11, and the lower end of the outer cylinder body 13 is correspondingly connected with the upper end of the inlet flange 15. The cross-section of the inlet flange 15 is also in the shape of an "i".
Two bearings 32 with dust covers are arranged between the rotary cylinder 11 and the outer cylinder 13 at intervals. Correspondingly, two shaft retainer rings 33 are mounted on the rotary cylinder 11 to limit the inner ring of the bearing 32, wherein the bearing 32 at the upper end of the rotary cylinder 11 is pressed by an upper bearing cover 39 to limit the outer ring. The lower end bearing 32 between the rotary cylinder 11 and the outer cylinder 13 restricts the axial displacement of the outer ring by the inlet flange 15.
The base 16 surrounds the outer periphery of the rotary drum 11, is interposed between the upper bearing cap 39 and the outer cylindrical body 13, and is fixed by a hexagon socket head cap 37, a spring washer 38, and a flat washer. Specifically, the base 16 is a horizontally disposed annular flat plate structure, one side of which is arc-shaped and the other side of which is rectangular, so that the design is convenient for the installation of subsequent components thereon.
Referring back to fig. 4, a plurality of bolt holes 161 are formed on the periphery of the base 16 for fixing the spraying structure 100 when it is installed on the net cage 200.
Meanwhile, the base 16 can realize the installation and fixation of the driving motor 17 and the limit switch 18.
In the present embodiment, the driving motor 17 is a stepping motor with a speed reducer, and the driving motor 17 can drive the rotary cylinder 11, the outlet flange 14 and the elbow 12 to rotate together.
As shown in fig. 4, the outer circumferential surface of the upper end flange 111 of the spin basket 11 has a plurality of teeth to form a first gear 112. The spray structure 100 further includes a second gear 34. The diameter of the second gear 34 is smaller than the diameter of the first gear 112, and the second gear 34 is engaged with the first gear 112 for speed reduction.
As shown in fig. 6, the output end of the driving motor 17, which is vertically upward and passes through the base 16, is connected to the second gear 34 by a flat key 35 and is fixed by a bushing 36, a hexagon socket head cap screw 37 and a spring washer 38. When the motor is started, the driving motor 17 drives the second gear 34 to rotate, which drives the first gear 112 to rotate, and the rotary drum 11 rotates therewith.
In this embodiment, the air feeding system further comprises a control assembly. The control assembly is electrically connected with the driving motors 17 of the 4 spraying structures 100 one by one, so that the independent operation of each spraying structure 100 is realized. In the process of practical application, when underwater operation, the control assembly is utilized, and which spraying structure 100 is adopted for feeding is conveniently determined according to the water flow direction. Of course, when the water flow is relatively calm, 4 of the spray structures 100 may be operated simultaneously, covering as large an area of the net cage 200 as possible.
Referring to fig. 7, a stopper 19 is horizontally installed on the upper end surface of the outlet flange 14 to rotate together with the rotary cylinder 11. The limiting member 19 is a flat plate structure, one end of which is fixed to the outlet flange 14 by bolts, and the other end of which extends out and is fan-shaped.
Two limit switches 18 are arranged on one side of the arc of the base 16 at intervals along the circumferential direction, and have a certain distance with the rotary drum 11, and the limit switches 18 are fixedly kept. The limit switch 18 is electrically connected with the driving motor 17. When the rotary cylinder 11 (the stopper 19) rotates, the one-side limit switch 18 can approach or contact the stopper 19 and is triggered thereby to control the reverse rotation of the rotary cylinder 11. During the process of the reverse rotation of the rotary drum 11, the limit switch 18 on the other side is triggered by the limit piece 19, and the rotary drum 11 is controlled to rotate reversely again, so that the reciprocating swing of the rotary drum 11 (the bent pipe 12) between the two limit switches 18 is realized.
The limit switch 18 is embodied as a proximity switch or a travel switch.
Further, the distance between the two limit switches 18 is adjustable to adjust the rotation angle of the rotary cylinder 11.
Correspondingly, referring to fig. 7 in combination with fig. 4, two switch brackets 4 are mounted on the base 16. The cross section of the switch bracket 4 is similar to a half I shape, the bottom of the switch bracket is provided with an adjusting hole 41, and the adjusting hole 41 is arc-shaped and is similar to a kidney-shaped hole. The switch bracket 4 is mounted on the base 16 via an adjusting hole 41 and a bolt in a position-adjustable manner. The limit switch 18 is locked to the bracket by upper and lower lock nuts 42 at the top end of the switch bracket 4. Of course, more threaded holes may be drilled in the base 16 to provide more mounting points for the bracket to adjust the position between the two proximity switches, thereby adjusting the swing angle of the spray structure 100.
Referring to fig. 8 and 9 in combination with fig. 6, the spraying structure 100 further includes a pad 51.
An inner wall of the upper opening of the inlet flange 15 is formed with an annular receiving groove 151, the spacer 51 has an annular structure and is received in the receiving groove 151, and the lower end of the rotary cylinder 11 is pressed against the upper surface of the spacer 51. An O-shaped sealing ring 52 is arranged between the cushion block 51 and the inlet flange 15, and the elasticity of the O-shaped sealing ring 52 is utilized to keep a certain pressure between the cushion block 51 and the rotary cylinder 11 so as to ensure sealing.
It should be noted that the material of the pad 51 is polytetrafluoroethylene. The polytetrafluoroethylene is acid-resistant, alkali-resistant and various organic solvents-resistant, has an extremely low friction coefficient and can be used for lubrication. Therefore, the pad 51 made of polytetrafluoroethylene and the rotary drum 11 made of metal can reduce friction therebetween when they rotate, and reduce wear on the rotary drum 11.
Further, as shown in fig. 8, the upper end edge of the inlet flange 15 is provided with a groove 152, and the groove 152 is communicated with the receiving groove 151. As shown in fig. 9, the pad 51 is provided with a protrusion 511 protruding in the radial direction on the periphery thereof, and the protrusion 511 is correspondingly engaged with the groove 152. The two are clamped together during assembly, and the damage of the sealing ring caused by the rotation of the cushion block 51 is prevented. As described above, since the bearing 32 has an extremely low load and an extremely low rotation speed, the inner and outer races of the bearing 32 with the dust cap are both in clearance fit.
In conclusion, the air feeding system mainly used for the large deep-sea net cage 200 provided by the invention ensures a larger spraying range, does not need to add an expensive cross-brace structure on the net cage 200, and only needs to arrange the spraying structure 100 at the edge of the net cage 200, thereby avoiding fish snatching caused by concentrated feeding and reducing death caused by mutual pricking. The spraying angle is adjusted flexibly, the swinging speed can be adjusted by utilizing the stepping motor, and if the control system ignores the signal of the limit switch 18, the device can also be used as a rotary spraying structure to carry out 360-degree feeding.
When the spraying structure 100 works, bait is driven by wind power to enter the rotary cylinder 11 from the feeding pipe 300 through the inlet flange 15 at the lower end, and finally is sprayed out from the bent pipe 12. Meanwhile, the driving motor 17 drives the rotary cylinder 11, the outlet flange 14, the elbow pipe 12 and the limiting piece 19 to rotate through gears. Wherein, the locating part 19 is fan-shaped, and when the locating part 19 rotated to the limit switch 18 of both sides, limit switch 18 can output the switching value signal, and control system received the signal after, control driving motor 17 reversal, so reciprocal, realized spraying structure 100's reciprocating motion, increased spraying structure 100's the area that sprays.
