[0033] Reference Figures 1-4 , according to an embodiment of a vortex pump head with adjustable partition position of the utility model, comprises a pump casing 11, a pump chamber 12 is provided in the pump casing 11, and a water inlet pipe 13 and a water outlet pipe 14 are provided on the side of the pump casing 11, the water inlet pipe 13 and the water outlet pipe 14 are respectively provided with a flow channel connected to the pump chamber 12, and an impeller 15 is rotatably connected in the pump chamber 12. When the rotating shaft connected to the impeller 15 is driven by the motor to make the impeller 15 rotate, the liquid will enter the pump chamber 12 through the water inlet pipe 13 and be pumped out through the water outlet pipe 14 after acceleration. In addition, in order to prevent water from backflowing at the water inlet pipe 13 and the water outlet pipe 14 in the pump chamber 12, a partition 16 is also included, and the partition 16 is located between the water inlet pipe 13 and the water outlet pipe 14. In addition, a positioning device for controlling the distance between the partition 16 and the impeller 15 is also included.

[0034] In this embodiment, the positioning device includes a boss 17 provided on the pump housing 11, the boss 17 is located between the water inlet pipe 13 and the water outlet pipe 14, and the boss 17 is provided with a slide groove 18 that is connected to the pump chamber 12 and passes upward, the upper side surface of the partition 16 is provided with a control plate 19 extending into the slide groove 18, an abutment plate 20 is connected to the slide groove 18 for sliding back and forth, and a threaded shaft 21 threadedly connected to the abutment plate 20 is rotatably connected to the front side surface of the boss 17, and a locking knob 22 is provided on the threaded shaft 21.

[0035] Furthermore, a cover plate 23 is included, which covers the upper side of the sliding groove 18 and shields the control panel 19 .

[0036] When the staff adjusts the distance of the partition 16 relative to the impeller 15, the staff can put their hands into the slide groove 18 during the adjustment process and control the partition 16 more intuitively. After the position adjustment of the partition 16 and the control panel 19 is completed, the staff rotates the locking knob 22 and presses the abutment plate 20 against the control panel 19. At this time, the control panel 19 and the partition 16 are locked in the upper and lower positions.

[0037] In order to prevent the abutment plate 20 from loosening due to the vibration generated during the operation of the vortex pump head with adjustable partition position, the locking knob 22 is designed to be connected to the threaded shaft 21 for forward and backward sliding, and a friction member is provided between the rear side surface of the locking knob 22 and the wall surface of the boss 17, and also includes a locking mechanism for controlling the forward and backward position of the locking knob 22.

[0038] In this embodiment, the friction member includes a rubber ring 24 provided on the wall surface of the boss 17 and a rubber block 25 provided on the rear side surface of the locking knob 22 and capable of affixing to the rubber ring 24. The rubber blocks 25 are provided in plurality and are distributed at equal angles with the axis of the locking knob 22 as the center. That is, when the locking knob 22 approaches the boss 17, the rubber blocks 25 can affix to the rubber ring 24 to increase friction, prevent the locking knob 22 from rotating, and prevent the abutment plate 20 from moving.

[0039] The locking mechanism includes a pressure plate 26 , a plurality of springs 27 are provided on the rear side of the pressure plate 26 , and the pressure plate 26 is connected to the threaded shaft 21 through a snap assembly;

[0040] The buckle assembly includes a slot 28 provided in the threaded shaft 21, and outward-through bayonet holes are provided on the upper and lower sides of the slot 28. An inserting plate 29 capable of being inserted into the slot 28 is rotatably connected to the rear side surface of the pressure plate 26, and a hook plate capable of being inserted into the bayonet hole is integrally formed on the inserting plate 29.

[0041] That is, when the inserting plate 29 is inserted into the card slot 28, the hook plate is locked in the card slot, and at this time the spring 27 presses the locking knob 22 onto the boss 17 and locks it. At this time, the locking knob 22 cannot be rotated. When the staff needs to rotate the locking knob 22 to adjust the position of the partition 16, the staff needs to insert a slender object into the card slot and squeeze the hook plate, so that the inserting plate 29 can be pulled forward. After that, the staff can rotate the locking knob 22 that is not pressed and enable the control panel 19 to be adjusted up and down.

[0042] In addition, in order to further protect the locking knob 22, the rear side of the pressure plate 26 is provided with a cover 30 covering the locking knob 22, and in order to facilitate the disassembly of the pressure plate 26 and the inserting plate 29, the cover 30 is provided with a slot for the slender object to pass through.

[0043] In the second embodiment of the vortex pump head with adjustable partition position, in order to facilitate the staff to accurately adjust the upper and lower positions of the partition 16 and the control plate 19, an adjustment mechanism is also included, and the adjustment mechanism includes a control frame 32 arranged on the rear side of the boss 17, and a turntable 33 is rotatably connected in the control frame 32, a vertical groove 51 is provided in the control plate 19, and the rear side surface of the vertical groove 51 is provided with an inclined groove 52 that passes through backward and is inclined left and right, the turntable 33 is equipped with a lifting rod 34 extending into the vertical groove 51, and the front end of the lifting rod 34 is equipped with a friction wheel 35 that can be attached to the side of the vertical groove.

[0044] It also includes a deceleration mechanism, which includes an inner gear ring 36 installed on the rear side of the turntable 33. A control rod is rotatably connected in the control frame 32, and the front end of the control rod is equipped with a gear engaged with the inner gear ring 36, and the rear end of the control rod is equipped with an adjustment knob 37.

[0045] In addition, the lifting rod 34 is connected to the rotating disk 33 in a forward and backward sliding manner, and the lifting rod 34 extends forward to the front side of the control frame 32;

[0046] The lifting rod 34 is provided with a protruding ring 38 that can abut against the inner wall or outer wall of the control frame 32 .

[0047] Specific method for adjusting the position of the partition 16:

[0048] First, the staff pulls the lifting rod 34 backward and makes the friction wheel 35 leave the vertical groove 51 and enter the inclined groove 52. At this time, the friction wheel 35 does not contact any wall surface, so that the partition 16 is downward. Then the staff passes through the slide groove 18 and presses down the partition 16 and the control plate 19 by hand until the partition 16 rests on the impeller 15. Then the staff pushes the lifting rod 34 forward and makes the friction wheel 35 enter the vertical groove. At this time, the friction wheel 35 is attached to the side of the vertical groove. Then the staff turns the adjusting knob 37. When the adjusting knob 37 rotates, it decelerates and drives the lifting rod 34 and the friction wheel 35 to rotate through the gear and the inner ring gear 36, so that the control plate 19 and the partition 16 slowly move upward.

[0049] When the distance between the partition plate 16 and the impeller 15 reaches a predetermined value, the staff rotates the locking knob 22 to make the abutting plate 20 abut against the control plate 19 , and the position of the control plate 19 is locked.

[0050] Afterwards, the staff inserts the insert plate 29 into the slot 28. At this time, the cover 30 covers the locking knob 22, and the locking knob 22 is pressed onto the boss 17 by the spring, so that the locking knob 22 can no longer rotate. Then the staff pushes the lifting rod 34 backward and makes the friction wheel 35 leave the vertical slot. At this time, the position adjustment of the partition 16 is completed.

[0051] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
