Specific implementation mode
Embodiment one：
As shown in Fig. 2, 2 pedestal 21 of sand throwing apparatus is circle, sand-throwing ring 22, notopodium 24 with together with of axle sleeve 23 are provided with,
One of notopodium 24 includes 4 blades, and 22 outer edge of sand-throwing ring is distributed in by axis of base center axis.As shown in figure 3, diving electricity
Machine includes shaft 1 and machine capping 3, and sand throwing apparatus 2 is fixedly installed in by axle sleeve 23 in shaft 1, and it is round that machine covers the setting of 3 outer end faces
Boss 31,31 outer diameter of boss is less than 22 internal diameter of sand-throwing ring, and sand-throwing ring 22 is placed on outside boss 31, forms resistance sand gap between the two
5, mechanical seal 4 is arranged in 3 inside of machine capping.
When motor works, sand throwing apparatus 2 is rotated with shaft 1, and one of rotation of notopodium 22 generates pressure, stops the grains of sand, hinders sand
Gap 5 effectively can prevent the grains of sand from entering since 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, the grains of sand dirt that blocking passes through resistance sand gap.
Embodiment two：
As shown in figure 4,2 pedestal 21 of sand throwing apparatus is circle, sand-throwing ring 22, axle sleeve 23 and two notopodiums 25 are provided with,
Two notopodiums 25 include 2 blades, and 23 outer edge of axle sleeve is distributed in by axis of base center axis.As shown in figure 5, submersible motor
Including shaft 1 and machine capping 3, sand throwing apparatus 2 is fixedly installed in by axle sleeve 23 in shaft 1, and it is circular that machine covers the setting of 3 outer end faces
Boss 31,31 outer diameter of boss are less than 22 internal diameter of sand-throwing ring, and sand-throwing ring 22 is placed on outside boss 31, form resistance sand gap 5 between the two,
Mechanical seal 4 is arranged in 3 inside of machine capping.
When motor works, sand throwing apparatus 2 is rotated with shaft 1, and resistance sand gap 5 can effectively prevent the grains of sand since 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 generate pressure by rotation, and blocking cavity external world grains of sand dirt enters,
Mechanical seal 4 is last sealing together, and blocking goes successively to motor by hindering the grains of sand dirt in sand gap.
Embodiment three：
