In figure:1- rotating shafts, 2- sand throwing apparatus, 21- bases, 22- sand-throwing rings, 23- axle sleeves, one of notopodium of 24-, 25- bis- are carried on the back Leaf, the capping of 3- machines, 31- boss, 4- mechanical seals, 5- resistance sand gap.
Embodiment
Embodiment one:
As shown in Fig. 2 the base 21 of sand throwing apparatus 2 is circle, sand-throwing ring 22, notopodium 24 with together with of axle sleeve 23 are provided with, together Notopodium 24 includes 4 blades, and the outward flange of sand-throwing ring 22 is distributed in by axis of base center axle.As shown in figure 3, submersible motor bag Rotating shaft 1 and machine capping 3 are included, sand throwing apparatus 2 are fixedly installed in rotating shaft 1 by axle sleeve 23, and machine covers 3 outer faces and sets the convex of circle Platform 31, the external diameter of boss 31 are less than the internal diameter of sand-throwing ring 22, and sand-throwing ring 22 is placed on outside boss 31, form resistance sand gap 5, machine between the two The inner side of capping 3 sets mechanical seal 4.
When motor works, sand throwing apparatus 2 rotate with rotating shaft 1, and one of rotation of notopodium 22 produces pressure, stops the grains of sand, hinders sand Gap 5 effectively can prevent the grains of sand from entering because gap is long and narrow, and the chamber of a semi-hermetic is formed between sand throwing apparatus 2 and machine capping 3, Only few grains of sand dirt can avoid one of notopodium and enter intracavitary by hindering sand gap, and mechanical seal 4 is last one Sealing, stops the grains of sand dirt by hindering sand gap.
Embodiment two:
As shown in figure 4, the base 21 of sand throwing apparatus 2 is circle, sand-throwing ring 22, the notopodium 25 of axle sleeve 23 and two are provided with, two Notopodium 24 includes 2 blades, and the outward flange of axle sleeve 23 is distributed in by axis of base center axle.As shown in figure 5, submersible motor includes Rotating shaft 1 and machine capping 3, sand throwing apparatus 2 are fixedly installed in rotating shaft 1 by axle sleeve 23, and machine covers 3 outer faces and sets circular boss 31, the external diameter of boss 31 is less than the internal diameter of sand-throwing ring 22, and sand-throwing ring 22 is placed on outside boss 31, forms resistance sand gap 5, machine envelope between the two The inner side of lid 3 sets mechanical seal 4.
When motor works, sand throwing apparatus 2 rotate with rotating shaft 1, and resistance sand gap 5 can effectively prevent the grains of sand because gap is long and narrow Into the chamber of one semi-hermetic of formation, only few grains of sand dirt can avoid one of back of the body between sand throwing apparatus 2 and machine capping 3 Leaf simultaneously enters intracavitary by hindering sand gap, and two notopodiums 25 produce pressure by rotating, and stop that cavity external world grains of sand dirt enters, Mechanical seal 4 seals together to be last, stops and goes successively to motor by hindering the grains of sand dirt in sand gap.
Embodiment three:
As shown in fig. 6, the base 21 of sand throwing apparatus 2 is circle, sand-throwing ring 22, axle sleeve 23, one of notopodium 24 and two are provided with Notopodium 25, one of notopodium 24 include 8 blades, the outward flange of sand-throwing ring 22, two notopodiums are distributed in by axis of base center axle 24 include 8 blades, and the outward flange of axle sleeve 23 is distributed in by axis of base center axle.As shown in fig. 7, submersible motor includes rotating shaft 1 and machine capping 3, sand throwing apparatus 2 are fixedly installed in rotating shaft 1 by axle sleeve 23, and machine covers 3 outer faces and sets circular boss 31, The external diameter of boss 31 is less than the internal diameter of sand-throwing ring 22, and sand-throwing ring 22 is placed on outside boss 31, forms resistance sand gap 5, machine capping 3 between the two Inner side sets mechanical seal 4.
