The utility model discloses simple of structure, convenient to use can prevent effectively that the water pump reversal from leading to dangerous.
Description
Technical Field
The utility model relates to the field of machinary, especially, relate to a waterproof pump reversal structure.
Background
The water pump sometimes leads to the water pump reversal because positive negative pole connects the mistake. And such errors are difficult to detect prior to power-up. The water pump can cause the flabellum to rotate in reverse direction after being connected by mistake, which can cause great danger in the use process, especially in chemical production, so a structure for preventing the water pump from reversing needs to be designed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a waterproof pump reversal structure. The utility model discloses simple of structure, convenient to use can prevent effectively that the water pump reversal from leading to dangerous.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a waterproof pump anti-rotation structure, includes motor spindle, and motor spindle hub connection has the sleeve pipe, forms the spacing ring on the sleeve pipe, and neighbouring spacing ring is formed with flabellum main part installation department, and neighbouring flabellum main part installation department is formed with external screw thread portion, and external screw thread portion threaded connection has fixation nut, the interior terminal surface of sleeve pipe is fixed with a plurality of pivots, and the hub connection has the pawl in the pivot, is fixed with the ratchet that corresponds with the pawl on the motor spindle.
In a further improvement, the pawl is connected with the rotating shaft through a torsion spring.
In a further improvement, the rotating shafts are multiple and are uniformly distributed on the inner end surface of the sleeve along the circumferential direction.
In a further improvement, the motor main shaft is connected with the sleeve through a bearing in a shaft joint mode.
In a further improvement, the fixing nut is a hexagonal nut.
The beneficial effects of the utility model reside in that:
the utility model discloses simple of structure, convenient to use can prevent effectively that the water pump reversal from leading to dangerous.
Drawings
The present invention is further explained by using the attached drawings, but the content in the attached drawings does not constitute any limitation to the present invention.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1, the waterproof pump reverse structure includes a motor spindle 1, a sleeve 2, a limit ring 3, a fan blade body mounting portion 4, an external thread portion 5, a fixing nut 6, a pawl 7, a ratchet 8, a rotating shaft 9 and a bearing 10.
The motor spindle 1 is coupled with a sleeve 2 through a bearing 10, a limit ring 3 is formed on the sleeve 2, a fan blade main body mounting part 4 is formed adjacent to the limit ring 3, an external thread part 5 is formed adjacent to the fan blade main body mounting part 4, the external thread part 5 is in threaded connection with a fixing nut 6, and the fixing nut 6 is a hexagon nut. The inner end face of the sleeve 2 is fixed with a plurality of rotating shafts 9, and the plurality of rotating shafts 9 are uniformly distributed on the inner end face of the sleeve 2 along the circumferential direction. The rotating shaft 9 is connected with a pawl 7 through a torsion spring in a shaft mode, and a ratchet wheel 8 corresponding to the pawl 7 is fixed on the motor main shaft 1.
The utility model discloses during the use, fix the flabellum main part fast through spacing ring 3 and fixation nut 6. When the water pump is started, if the motor spindle 1 turns correctly, the ratchet 8 is driven to rotate through the pawl 7, and then the sleeve 2 and the fan blade body are driven to rotate to pump water. Because the pawl 7 can only drive the ratchet wheel 8 to rotate towards one direction, when the rotation direction of the motor spindle 1 is opposite to the correct direction, power cannot be transmitted to the sleeve 2 and the fan blade main body, and therefore the water pump is prevented from rotating reversely.
It should be finally noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
