Description

Buoy for measuring flow velocity

Technical Field

The utility model belongs to the technical field of hydrological measurement equipment, specifically be a buoy of measurement velocity of flow.

Background

Float-based flow measurement is one method of measuring flow rate. This is the simplest and easiest way to do. It uses a piece of wood or a bottle filled with a small amount of water, and inserts a small flag on the wood or the bottle mouth as a float, and uses a watch to measure the time of the float through two points in a bay or a river which are separated by a certain distance, so as to obtain the flow speed. The speed is usually expressed by meters per second, during measurement, a regular section of river bed with length not less than 10m, no bending and certain liquid level height is taken, the average width and the water level height are measured, a floating object is taken and placed in the center of the upstream of flowing river water, the floating object flows through the measured distance under the influence of no external force (such as wind, floating object blockage and the like), and the flowing time is recorded. The method is repeated for several times, the average value is obtained, the buoy is the most important equipment for flow measurement by a buoy method, and the existing buoys need to be manually placed in the center of a river channel and are not convenient to recover; the required buoy counter weight of the river course of different water depths is different, and the measurement operation of being not convenient for is inconvenient discernment under dim condition.

Disclosure of Invention

The purpose of the invention is as follows: to the not enough that exists among the prior art, the utility model aims to provide a buoy of measurement velocity of flow to solve present buoy and need the manual work to place in river course central position, and be not convenient for retrieve, the measurement operation of being not convenient for, problem of inconvenient discernment under dim condition.

The technical scheme is as follows: in order to solve the technical problem, the utility model discloses a technical scheme be:

the utility model provides a buoy of measurement velocity of flow, includes the cabin body, screw, counter weight frame and support frame, the cabin body is the round platform form, and the top of the cabin body installs the strobe light, the internally mounted of the cabin body has battery and controller, cabin body lower extreme is connected with the support frame, and installs screw and plectrum in the support frame, the support frame is sealed from top to bottom about, is provided with the opening around, the support frame lower extreme is connected with the counter weight frame, the counter weight frame divide into 3 counter weight storehouses, sets up about 3 counter weight storehouses.

Furthermore, the outer surface of the cabin body is provided with 2 reflective strips.

Furthermore, the propeller, the shifting sheet and the opening of the support frame are in the same direction, the propeller is in front, and the shifting sheet is behind.

Furthermore, the counterweight frame is arranged under the support frame and is fixedly connected with the support frame.

Furthermore, the counterweight frame is square, and a flanging is arranged on the 3 surfaces of the partition plates in the middle of the counterweight frame.

Has the advantages that: compared with the prior art, the method has the following advantages:

this measure buoy of velocity of flow is equipped with strobe light and reflection of light strip, be convenient for discernment and measure under dim condition, the buoy is equipped with the drive of similar hull and turns to the structure, can go forward fast with the regulation through controller control buoy trend, and the buoy bottom is provided with adjustable balancing weight, increases and decreases the counter weight according to actual conditions, improves the suitability, and this measure buoy overall design of velocity of flow is small and exquisite convenient moreover, conveniently carries.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-2, the buoy for measuring flow rate of the present application comprises a cabin 1, a strobe light 2, a propeller 3, a plectrum 4, a counterweight frame 5, a storage battery 6, a controller 7 and a support frame 8, wherein the cabin 1 is in the shape of a circular truncated cone, the top end of the cabin body 1 is provided with a stroboscopic lamp 2, the stroboscopic lamp 2 is connected with a storage battery 6 in the cabin body 1 through a lead, the storage battery 6 and a controller 7 are arranged in the cabin body 1, the controller 7 is an AB433E type control module and supports remote control, the lower end of the cabin body 1 is connected with a support frame 8, and install screw 3 and plectrum 4 in the support frame 8, the removal of this buoy of screw 3 control, the direction of this buoy of plectrum 4 control, the support frame 8 is sealed from top to bottom and left and right sides, is provided with the opening around, and the support frame 8 lower extreme is connected with counterweight housing 5, and counterweight housing 5 divide into 3 counter weight storehouses, and 3 counter weight storehouses set up from top to bottom, and the user can carry out the counter weight according to the waters of difference.

The outer surface of the cabin body 1 is provided with 2 reflecting strips, and the reflecting strips and the stroboscopic lamp 2 are used for improving the identification degree of the buoy under the dim condition and improving the controllability.

The screw 3 and the poking piece 4 are in the same direction with the opening of the supporting frame 8, the float can be better controlled by the screw 3 and the poking piece 4, the screw 3 is in front, and the poking piece 4 is in back.

The weight frame 5 is arranged under the support frame 8, so that the buoy is more stable in drifting and is not easy to topple over, the weight frame 5 and the support frame 8 are fixedly connected, and the fixed connection can prevent the buoy from loosening between the weight frame 5 and the support frame 8 due to long-time use.
