Oxygen increasing machine

Technical Field

The invention relates to technical improvement of fishery production equipment, in particular to an aerator with an improved structure.

Background

The motor of the existing aerator basically has the heat dissipation requirement, and the heat dissipation requirement is considered, the motor shell is usually expected to be as thin as possible, the heat dissipation performance of the over-thin shell is relatively good, but the rigidity of the motor shell is reduced, the motor or the aerator is easy to break down, and the heat dissipation and the rigidity of the motor shell of the aerator have the contradiction in design. In addition, the existing aerator has the problem of the other aspect, namely, the connection between the motor and the impeller and the floating body is mostly a frame or a connecting rod, the frame or the connecting rod is usually welded or connected on the motor by a fastener, and the frame or the connecting rod is also connected with the floating body by the fastener, so that the aerator is difficult to rust in long-time underwater work, and is difficult to disassemble and assemble the frame or the connecting rod with the motor and the floating body during maintenance.

Disclosure of Invention

The invention mainly aims to provide the aerator with good rigidity and heat dissipation performance;

the invention also aims to provide the aerator which is convenient to maintain and repair.

In order to realize the main purpose of the invention, the aerator provided by the invention comprises a motor, a floating body and a connecting rod for connecting the motor and the floating body; the placing groove is used for placing a fixed end of the connecting rod connected with the motor and consists of a motor shell and two wing plates extending outwards from the outer surface of the shell to the motor.

According to the scheme, the arrangement groove formed by the two wing plates is formed in the outer surface of the motor shell, so that on one hand, the rigidity of the motor shell is enhanced, and meanwhile, the heat dissipation fin plate on the motor shell is formed, and the heat dissipation performance of the motor is improved.

The aerator further comprises a quick locking mechanism, and after the fixed end is in place in the placing groove, the quick locking mechanism is used for locking and stopping the fixed end and the placing groove mutually. This scheme has adopted quick locking mechanical system to carry out fixed connection and stopping with the stiff end of connecting rod and the mounting groove of motor, and compared with the connected mode that adopts welding or many fasteners in prior art, has the installation and dismantles all convenient advantage, the maintenance and the maintenance of the oxygen-increasing machine of being convenient for very much.

The other further scheme is that the outer surface of the motor shell is surrounded by an upper surface, a lower surface and a side surface connecting the upper surface and the lower surface, and the placement groove is arranged on the lower surface, the upper surface or the side surface.

The other further proposal is that one end of the length direction of the placing groove is provided with a gland covering the opening of the placing groove, and the quick locking mechanism is positioned at the other end of the length direction of the placing groove. The setting of gland makes being connected of connecting rod and motor more firm in this scheme.

The further proposal is that the gland is provided with a button tooth extending into the placing groove, and the fixed end of the connecting rod is provided with a tooth hole matched with the button tooth. After the button tooth is buckled into the tooth hole, the fixed end of the connecting rod is further stably fixed in the placing groove.

Still another scheme is that quick locking mechanism includes the tooth that sets up the elasticity pawl and cooperate with elasticity pawl on the connecting rod in the inboard of pterygoid lamina. When the fixed end of the connecting rod is pressed into the groove bottom from the notch of the placing groove, the elastic pawl is pressed and retracted, and after the elastic pawl is placed in place, the pawl is popped out and clamped into the ratchet, so that quick locking is realized.

The connecting rod is further provided with a plug-in sheet for disengaging the pawl from the ratchet. When the connecting rod needs to be detached from the motor, the inserting piece is pressed to enable the pawl to retract, and then the locking can be released for detaching.

Still a further scheme is that quick locking mechanical system is including setting up screw on the pterygoid lamina, lockhole and bolt tapered end on the connecting rod, and the bolt tapered end cooperates with the screw, and the tapered end is screwed into in the lockhole. When the fixed end of the connecting rod is pressed into the groove bottom from the notch of the placing groove to be in place, the bolt lock head is screwed tightly, so that the lock head can enter the lock hole to be quickly locked, and the bolt lock head is screwed back to withdraw from the lock hole to be quickly disassembled.

The floating body is provided with a mounting hole which is vertically arranged; the other end of the connecting rod, which is far away from the fixed end, is a vertical straight rod; the straight rod is in interference fit with the mounting hole, and the straight rod is inserted into the mounting hole from top to bottom. The scheme ensures that the connection of the connecting rod and the floating body also meets the requirement of quick assembly and disassembly, and is more convenient to maintain.

The upper end of the mounting hole is provided with a height limiting sleeve, and the straight rod sequentially penetrates through the height limiting sleeve and the mounting hole. The arrangement of the height limiting sleeve can effectively prevent the connecting rod from wearing the floating body.

The present invention will be described in more detail below with reference to embodiments and the accompanying drawings.
