Embodiment 1

[0031] A strong tracking float suitable for the prototype observation of the flow velocity distribution in the entrance area of ​​the navigation hub, including the floating plate 3, the motor 2, the threaded screw rod 12 and the water flow plate 10, and also includes the rotating device 11 and the limit column 8, the upper surface of the floating plate 3 The motor 2 is fixedly installed on the right side of the middle part, the upper end of the motor 2 is fixedly connected with the shaft center of the rotating gear 1, the rotating gear 1 is meshed and connected with the mobile device, the lower end of the mobile device is fixedly connected with the middle part of the upper surface of the floating plate 3, and the internal thread of the mobile device is sleeved with Threaded screw rod 12, the lower end of threaded screw rod 12 is fixedly connected with the interior of the rotating device 11, the left and right sides of the upper surface of the rotating device 11 are fixedly conne...

Embodiment 2

[0034] Embodiment 2: the difference based on Embodiment 1 is;

[0035] The rotating device 1 includes a fixed casing 13, a sealing plate 20, a fixed turntable 18, a fixed part 19 and a moving part 9, the upper end of the fixed casing 13 is fixedly connected with the lower surface of the sealing plate 20, the fixed turntable 18 is fixedly sleeved inside the fixed casing 13, and fixed The axis of the turntable 18 is meshed with the ratchet 16, and the axis of the ratchet 16 is fixedly connected with the lower end of the screw rod 12. The upper surface of the ratchet 16 is evenly provided with four limit posts 26 in a circular ring. The inner end is movably connected, the outer end of the fixed part 19 is movably connected with the upper end of the transmission column 25, the lower end of the transmission column 25 is fixedly connected with the upper part of the inner end of the moving part 9, and the outer side of the moving part 9 is movably connected with the fixed shell 13. T...

Embodiment 3

[0037] Embodiment 3: the difference based on embodiment 1 and 2 is;

[0038] The left and right sides of the middle part of the limit groove 22 are provided with draw-in grooves 21, and the left and right sides of the upper end of the limit column 8 are movably sleeved with bayonet pins 24. The bayonet pin 24 is matched; the shell of the floating plate 3 is made of acid, alkali and ozone resistant TPE material, and the inside is filled with pearl cotton material.

[0039] The present invention is also provided with a limiting column 8, when in use, the rotating device 11 can be ejected through the threaded screw rod 12, so that the bayonet pin 24 on the upper end of the limiting column 8 is separated from the draw-in groove 21, so that the rotating device 11 and The floating plates 3 are separated from each other. When recovering, it is only necessary to align the limiting column 8 with the limiting groove 22 and push upwards, so that the locking pin 24 on the upper end of the...

Abstract

The invention, which belongs to the field of water body monitoring, discloses a strong tracking floater for prototype observation of flow velocity distribution in a gate area of a navigational junction. When the strong tracking floater is in use, the floater only needs to be placed in water; a motor is started to drive a rotating gear to rotate, a rotary knob is driven to rotate, and a rotating tube is driven to rotate, so that an internal thread rotating rod is driven to move down slowly; and the declining height of the thread rotating rod is adjusted based on the water depth needing measurement. When the thread rotating rod starts to move down, a rotating device is pushed out and thus enables a water flowing plate to be spread, so that the flowing velocity and direction of the water bodyare measured by the water flowing plate.

Description

technical field [0001] The invention relates to the field of water body monitoring, in particular to a strong tracking float suitable for the prototype observation of flow velocity distribution in the entrance area of ​​a navigation hub. Background technique [0002] After the construction of water conservancy, hydropower, and navigation-power hub projects in natural rivers, in order to ensure navigation, navigation structures such as ship locks or ship lifts are often installed. At the entrance and exit of navigable buildings, that is, the entrance area where the upper and lower approach channels of the ship lock are connected with the river (or canal), the water flow in this area is generally composed of oblique water flow and return flow, and is the passage for ships passing the lock to enter and exit the approach channel. throat. It is located at the junction of the flowing water of the river and the still water of the approach channel. Due to the particularity of this ...
