The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises that one is used to install the frame 1 of fountain, the many floating drums 2 of installation below frame 1, the difference that producible buoyancy summation deducted device and gross weight of equipment amount when floating drum 2 all was immersed in the water wants enough big, so that frame enough stabilizations of acquisition when being sunken to hydrolocation.One submersible motor 3 is set at the middle part of frame 1, the output of submersible motor 3 connects two winch spools 5 by a transmission mechanism 4, fix an end of one group of two cable wire 6 on two winch spools 5 respectively, the other end of two groups of cable wires 6 is two ends symmetry extension to the left and right respectively, and respectively separately by a distributor 7, every cable wire 6 is separately walked around a pulley 8 respectively and is turned four angles to frame 1, and another pulley 9 by being installed in the bight is to extending under water, after walking around the pulley 11 on the fixing underwater carrier 10 then, return and be separately fixed on the holder 12 at edge, frame 1 middle part.

In the foregoing description, transmission mechanism 4 must have self-locking performance, can take following structure, as shown in Figure 2, the output of motor 3 connects a worm screw 41, and worm screw 41 drives a worm gear 42, and the output shaft of worm gear 42 connects a driving gear 43, the both sides of driving gear 43 are meshed a driven gear 44,45 respectively, connect an above-mentioned winch spool 5 on the gear shaft of each driven gear 44,45.Transmission mechanism 4 also can adopt other to have the reducing gear of self-locking performance.

In the foregoing description, for the erosion of anti-sealing, transmission mechanism 4 should adopt good dynamic and static seal approach, and each cable wire 6, distributor 7, pulley 8,9 etc. all should adopt stainless steel material to make.

In the foregoing description, as shown in Figure 1 and Figure 2, every cable wire 6 is the primary load bearing section 61 12 from pulley 11 to holder, and the angle θ folded with frame 1 vertical center line 13 is acute angle; Equally, every cable wire 6 is the primary load bearing section 61 12 from pulley 11 to holder, and the angle φ folded with frame 1 longitudinal centre line 14 also is acute angle.
