Description

Technical Field

[0001] The utility model relates to the technical field of screw pumps, and more specifically to a movable screw pump. Background Art

[0002] Screw pump, also known as "screw pump" or "Archimedes screw pump". It is a kind of pump that uses the rotation of spiral blades to make water rise in an axial spiral shape. It consists of a shaft, spiral blades, and a casing. When pumping water, the pump is placed obliquely in the water so that the inclination angle of the water pump main shaft is smaller than the inclination angle of the spiral blades, and the lower end of the spiral blades is in contact with the water. When the prime mover drives the screw pump shaft to rotate through the speed change device, the water enters the blades and rises along the spiral flow channel until it flows out. It has a simple structure, is easy to manufacture, has a large flow rate, a small head loss, a high efficiency, and is easy to repair and maintain, but has a low head and a low speed, and a speed change device is required. It is mostly used in irrigation, drainage, and lifting sewage, sludge, and other occasions.

[0003] When existing movable screw pumps are used outdoors, in order to protect the motor from sunlight and rain erosion, a shielding shed is generally welded or installed with screws at the motor position of the screw pump. However, when the motor or the entire pump body is inspected and maintained, the shielding shed is rather in the way and needs to be dismantled, which is time-consuming and labor-intensive, reducing work efficiency. At the same time, the shielding shed generally only blocks the upper side of the motor. When the sun is oblique or there is a thunderstorm, the sun or rain will still irradiate or corrode the motor, thereby reducing the service life of the motor. There are certain disadvantages in its use.

[0004] In view of this, we propose a screw pump that is easy to move. Utility Model Content

[0029] Specifically, two sets of limiting grooves 12 for docking the threaded blocks 7 are opened on the inner side of the fixed frame 5. The limiting grooves 12 can limit the threaded blocks 7, so that when the threaded rod 6 rotates, the threaded blocks 7 can be driven to move parallel to the threaded rod 6, thereby facilitating the parallel movement of the protective frame 9.

[0030] Furthermore, a plurality of groups of moving wheels 13 are symmetrically arranged on the lower side of the base 1. By arranging the plurality of groups of moving wheels 13, the entire device can be conveniently moved, thereby facilitating the movement of the screw pump to a suitable position, thereby improving the flexibility of use.

[0031] It is worth mentioning that a threaded rod 14 is rotatably provided on the upper side of the base 1, a hand plate 15 is fixedly provided on the upper end of the threaded rod 14, and the lower end of the threaded rod 14 movably passes through the base 1 and extends to the lower side, and a fixed plate 16 is fixedly provided on the lower end of the threaded rod 14 at the lower part of the base 1. By rotating the hand plate 15, the fixed plate 16 can be easily driven to move downward and against the ground, thereby improving the flexibility of the device while ensuring the stability of the device during use.

[0032] It is worth noting that multiple sets of anti-skid grooves are provided on the outer sides of the turntable 10 and the hand plate 15. By providing the anti-skid grooves, the friction between the turntable 10 and the hand plate 15 can be increased, making the rotation of the turntable 10 and the hand plate 15 more convenient.

[0033] In addition, an anti-skid pad is fixedly provided on the lower side of the fixing plate 16 , and the anti-skid pad can increase the friction of the fixing plate 16 , so that the fixing effect of the device is better.

[0034] It has to be said that the heat dissipation mechanism 11 includes a rotating rod 17 rotatably arranged on the upper side of the protective frame 9, a mounting plate 18 is fixedly arranged on the upper end of the rotating rod 17, a plurality of impellers 19 are fixedly arranged on the outer side of the mounting plate 18, and the lower end of the rotating rod 17 movably passes through the protective frame 9 and extends to the inner side, and the lower end of the rotating rod 17 is located on the inner side of the protective frame 9 and is fixedly provided with fan blades 20, the rotating rod 17 is rotatably connected to the protective frame 9 through a bearing, the impeller 19 can rotate with the help of external wind, and when the impeller 19 rotates, it can drive the mounting plate 18 and the rotating rod 17 to rotate, and when the rotating rod 17 rotates, it drives the fan blades 20 to rotate, thereby facilitating the heat dissipation of the motor 4 in the protective frame 9 and ensuring the normal use of the motor 4.

[0035] Working principle: first, move the entire device to a suitable position through the moving wheel 13, and then rotate the multiple sets of hand plates 15 to drive the threaded rod 2 14 to rotate. The rotation of the threaded rod 2 14 drives the fixed plate 16 to move until the fixed plate 16 is against the ground, so that the entire device can be fixed for use. When the motor 4 needs to be repaired, the turntable 10 can be rotated to drive the threaded rod 1 6 to rotate. At this time, the two sets of threaded blocks 7 mounted on the outside of the threaded rod 1 6 move simultaneously along the threaded rod 1 6 under the limiting action of the limiting groove 12, and the distance becomes farther and farther. When the threaded block 7 moves, it drives the connecting block 8 and the protective frame 9 to move until the two sets of protective frames 9 move to the appropriate position. At this time, the motor 4 is exposed, which is convenient for the staff to repair and maintain the motor 4. Subsequently, by rotating the turntable 10 in the opposite direction, the two sets of protective frames 9 can be driven to move and merge, so that the motor 4 can be better protected.
