31 one end is connected with ultrasonic sensor 3, and the other end is connected with detection display on the bank.The front end of steel ruler 22 is installed with set
It is located at outside traction rope 31 and towards the telescoping tube of river surface axial stretching 23, the free end of telescoping tube 23 is connected to ultrasonic sensor
On 3.
Pedestal 1 is rectangular-shape structure, and the T-type for offering opening towards river surface on the end face opposite with river surface of pedestal 1 is long
Slot 11.T-type elongated slot 11 is through pedestal 1 across the both ends on riverbank.
Steel ruler 22 is placed in steel ruler distributor 2 by winding, and 22 front end of steel ruler stretches out steel ruler distributor 2 and is fastened on T
Between two shoulder inner sidewalls of type elongated slot 11.2 side of steel ruler distributor is equipped with wind 21, may be implemented by rotary handle crank 21
To the folding and unfolding process of steel ruler 22.
The telescoping tube 23 extended towards river surface is equipped in 22 end of steel ruler, telescoping tube 23 is gradually successively decreased by more piece caliber size
Hollow pipe be successively set with from big to small, can mutual telescopic moving between the adjacent hollow pipe of any two section.Wherein,
The one end of bore smaller conduit in the larger pipeline of adjacent bore is equipped with the follow block towards the inner wall radial protrusion of the larger pipeline of bore
231, the larger pipeline of bore covers one end outside adjacent bore smaller conduit equipped with the outer wall radial protrusion towards bore smaller conduit
Baffle 232, make adjacent hollow pipeline in being axially formed a kind of barrier relationship, telescoping tube 23 prevented to disconnect during the motion.
In addition, every section hollow pipe is equipped with the snap-gauge 233 radially protruded in one end close to river surface, so that the lesser sky of bore
Heart pipeline can be stuck at the port of the adjacent biggish hollow pipe of bore when shrinking；The maximum section card of 23 bore of telescoping tube
It is located in the opening of T-type elongated slot 11 and stretches out outside pedestal 1,22 end of steel ruler is limited；23 bore of telescoping tube is the smallest by one
Save close to river surface end face on be installed with clump weight 234 so that ultrasonic sensor 3 under the traction of traction rope 31 relative to
When pedestal 1 is transferred, telescoping tube 23 will not generate sliding interference due to engomphosis relation each other.
It is provided with the through-hole 221 of connection telescoping tube 23 vertically on 22 end face of steel ruler.Traction rope 31 detects display from bank
It draws, pierce into the T-type elongated slot 11 of pedestal 1 and is penetrated in telescoping tube 23 from through-hole 221.Axis of the traction rope 31 along telescoping tube 23
After line is pierced by telescoping tube 23, across clump weight 234 and it is connected on ultrasonic sensor 3.In order to reduce traction rope 31 and steel ruler
The pulley 222 being fixed on 22 end face of steel ruler vertically is arranged, wherein 221 axis of through-hole in the frictional force of 22 ends by through-hole 221

The implementation principle of the present embodiment are as follows: ultrasonic sensor 3 only need to slowly decontrol traction rope when being displaced downwardly to river surface
31, for telescoping tube 23 under the action of self weight and clump weight 234, free end can be connected to ultrasonic wave biography by clump weight 234
3 end of sensor, and stretching is synchronized with moving down for ultrasonic sensor 3, it is whole that position limitation protection is carried out to traction rope 31.
Ultrasonic sensor 3 needs to tighten traction rope 31 when moving up and far from river surface.Traction rope 31 pulls ultrasound at this time
Wave sensor 3 makes the top of ultrasonic sensor 3 resist clump weight 234, makes the lesser section of 23 bore of telescoping tube toward adjacent mouth
It is retracted in the biggish section of diameter, until telescoping tube 23 empties back into contraction state.
The telescoping tube for the free axial stretching of multistage that present embodiment is set in outside traction rope 31 in the setting of 22 end of steel ruler
23 limit traction rope 31, guarantee that ultra-sonic depth finder sensor will not be big because wind-force interferes in measurement process
Width is swung, to realize the precise measurement to river bed cross section shape.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
