The distribution points of the four driving mechanisms 3 are rectangular, and the centers of the distribution points of the four driving mechanisms 3 coincide with the center of the detection hull 2.

The drive mechanism 3 comprises a drive shaft 31 and a plurality of drive blades 32 arranged around the drive shaft 31, the drive shaft 31 being rotatably connected to the test hull 2 by means of a transmission 5, and the transmission 5 being rotatably connected to the outer wall of the test hull 2. The power output end of the power member 4 is connected to the transmission member 5, the driving shaft 31 can swing relative to the detection hull, and the swinging direction of the driving shaft 31 is inclined downwards and faces to the stern of the detection hull 2. Wherein, four drive shafts 31 of the week side one-to-one correspondence of detecting hull 2 are provided with four controls 21 that control four drive shafts 31 wobbling respectively, and power spare 4 is driving motor and its installation in the inboard that detects hull 2, and power spare 4's output shaft wears out to detect hull 2 and swivelling joint in detecting hull 2, and power spare 4's output shaft and detecting hull 2 are between set up through rotary seal circle is sealed.

Referring to fig. 1 and 2, further, a plurality of adjacent driving blades 32 are spirally arranged around the corresponding driving shaft 31, and the spiral directions of the driving blades 32 of two adjacent driving shafts 31 are opposite, so that the vertical projections of the driving blades 32 of two adjacent driving shafts 31 are V-shaped, and the openings of the V-shapes face or are far away from the detection hull 2. In the embodiment of the present application, the V-shaped opening is disposed toward a direction away from the detection hull 2, so that when the four driving shafts 31 rotate, the driving blades 32 corresponding to two adjacent driving shafts 31 generate a driving force parallel to the axial direction of the driving shafts 31, and the directions of the driving forces are opposite. When the four driving shafts 31 are parallel to each other, the blade surfaces of the driving blades 32 on the four driving shafts 31 are crossed with each other, and the cross line is the center of the four driving shafts 31.

Wherein, sealing ring plate 563 and expansion ring 562 are both made of water-swellable material, such as water-swellable rubber, sealing ring 561 is a sealing rubber ring, and wherein the sealing ring 561 is in contact with check valve 541.

When the oil filling hole is used, the sealing ring plate 563, the sealing ring 561 and the expansion ring 562 are pressed on the hole wall of the oil filling hole 54 by the blocking seat 552 under the action of the bolt, so as to perform preliminary sealing; because the transmission pipe 511 is immersed in water flow, part of water can contact the sealing ring plate 563 and the expansion ring 562, and at the moment, the sealing ring plate 563 and the expansion ring 562 can expand and extrude the hole wall of the oil filling hole 54, so that the sealing effect is optimized; in the process, the expanded expansion ring 562 synchronously extrudes the sealing ring 561, so that the sealing ring 561 is relatively more tightly attached to the hole wall of the oil injection hole 54, and because the outer walls of the sealing ring 561 and the expansion ring 562 are both in an arc surface-shaped structure, the sealing ring 561 can be more tightly attached to the hole wall of the oil injection hole 54 to further seal while water permeation is damaged; in addition, when the lubricating oil mist is replaced, the plugging block 55 is only required to be detached from the oil filling hole 54, and the lubricating oil mist is filled into the transmission pipe 511 through an oil filling instrument; at the same time, the lubricating oil mist in the spiral hole 512 and the lubricating oil hole 513 can be continuously replaced by swinging the driving shaft 31, so that the lubricating oil mist is smoother and more sufficient.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
