It is not provided with the lower mouth U-type groove 5-1-1-1 that Open Side Down.Two sides of seal case 5-1 are respectively connected by a fixed seat 5-2
It is connected on circulating water chennel 1, is connected between seal case 5-1 and fixed seat 5-2 by parts such as bolt, nuts.Further, Gu
Reservation 5-2 includes the fixed plate 5-2-1 and reinforcing rib 5-2-2 that are fixed on circulating water chennel 1, and wherein reinforcing rib 5-2-2 is fixed in
The both sides of fixed plate 5-2-1, for strengthening the rigidity of fixed plate 5-2-1.Fixed plate 5-2-1 pacifies for installing roller unit
It loads onto and states shaft 4-2.Be provided with the U-type groove 5-2-1-1 suitable for reading of opening upwards on fixed plate 5-2-1, during installation, the same side it is close
The U-type groove 5-2-1-1 suitable for reading on lower mouth U-type groove 5-1-1-1 and fixed plate 5-2-1 on joint sealing body 5-1 is corresponding, shaft 4-2
Across lower mouth U-type groove 5-1-1-1 and U-type groove 5-2-1-1 suitable for reading, and in the vertical direction can be relative to upper and lower mouth U-type groove 5-
1-1-1 is moved.
Specifically, seal case 5-1 and shaft 4-2 is tightly connected, the application does not limit its specific connection structure, makees
It is preferred, two-side sealing plate 5-3-1 is selected to be sealed.As shown in figure 9, two-side sealing plate 5-3-1 is placed in seal case 5-1
Between fixed seat 5-2, along in roller 4-1 axial directions, the displacement freedom and rotary freedom of two-side sealing plate 5-3-1 pass through admittedly
Reservation 5-2 and seal case 5-1 constraints, other degree of freedom are constrained by the shaft 4-2 being set on roller 4-1.It is specifically, double
Trepanning in the middle part of side sealing plate 5-3-1, shaft 4-2 run through the hole, when shaft 4-2 is moved up and down with bearing block 4-5, two-side sealing
Plate 5-3-1 is moved together with shaft 4-2.Adjustment hole 5-3-1-2 is provided on two-side sealing plate 5-3-1, in connection fixing base 5-2
During with seal case 5-1, bolt is passed through from the adjustment hole 5-3-1-2 of two-side sealing plate 5-3-1, and adjustment hole 5-3-1-2 ensures
Two-side sealing plate 5-3-1 can be moved up and down with shaft 4-2.The application does not limit the concrete shape of adjustment hole 5-3-1-2
Fixed, as preference, in the present embodiment, adjustment hole 5-3-1-2 uses waist-shaped hole.
Two-side sealing plate 5-3-1 is tightly connected by O-shaped sealing element 5-3-2 and seal case 5-1 and fixed seat 5-2.Make
To be preferred, the both sides of two-side sealing plate 5-3-1 are respectively arranged with the annular groove 5-3-1-1 of mounting O-shaped sealing element 5-3-2,
Under working condition, seal case 5-1 corresponding O-shaped sealing element 5-3-2 or fixed seat 5-2 are fitted closely, so as to fulfill
Seal case 5-1 two sides and the sealing of shaft 4-2.In order to ensure sealing effect, annular groove 5-3-1-1 is by above-mentioned adjustment hole
5-3-1-2 is surrounded in the middle, so as to avoid that the sealing of seal case 5-1 sides is destroyed at above-mentioned adjustment hole 5-3-1-2.Into one
Step, the lower end of two-side sealing plate 5-3-1 is immersed in the water, to ensure the sealing state of seal case 5-1 two sides.
Specifically, being additionally provided with suction port 5-1-2 on two-side sealing plate 5-3-1, suction port 5-1-2 passes through Liquid level
The control module control break-make of unit.Water level conditions control suction port 5- of the liquid level module in seal case 5-1
1-2, the application do not limit its specific control method, as preference, in the present embodiment, control module includes two detections
The sensor of water level, respectively low water level sensor and high water level sensor.When water level is down to low water level sensor position, control
Molding block opens suction port 5-1-2 automatically；When water level increases to the position of high water level sensor, control module disconnects pumping end
Mouth 5-1-2.The specific location of high water level sensor and low water level sensor is determined according to hydrodynamic test demand, as excellent
Choosing, the position of high water level sensor is higher than roller 4-1, it is therefore an objective to the water level in seal case 5-1 be made not have roller completely
4-1, the scope of freedom of liquid will not generate bubble in circulating water chennel 1 in this case, and the scope of freedom is more steady.In view of Liquid level
Unit is not the emphasis of the application protection, therefore the application does not elaborate it.
Specifically, liquid level module further includes liquid level gauge 6-1.Liquid level gauge 6-1 is set on seal case 5-1, is used for
Show the water level in seal case 5-1.
The feature and advantage of the application are described further below in conjunction with application method.Under working condition, control module
Water level in adjust automatically seal case 5-1, makes roller 4-1 be totally submerged in water.Gear unit will according to a stable drive ratio
The power of motor 2-1 passes to roller 4-1 by shaft 4-2, and then, roller 4-1 is imparted power in seal case 5-1
Water so as to which water be made to be immersed from the side of seal case 5-1, flows out in seal case 5-1 after speed governing from opposite side.According to experiment
Demand when needing to adjust roller 4-1 height, adjusts pine seal case 5-1 and fixed seat 5-2, in order to two-side sealing plate 5-3-1
Can move up and down, the bearing block 4-5 of both sides is then adjusted to suitable position, then again fixing seal babinet 5-1 and
Fixed seat 5-2, you can tested.
The present invention is used to carry out speed governing to the liquid on upper strata, both can be used for accelerating liquid, it can also be used to slow down, according to
Depending on specific requirements.It is particularly suitable for accelerating circulating water chennel 1, solves Free Liquid Surface system because caused by reducing speed
Row problem, so as to improve experimental precision.
