Abstract
The utility model discloses a kind of bar thread ball measurement in a closed series flow rate of water flow calculating instrument, including pulley calculating instrument, expansion link, float device and rubber bulb, described pulley calculating instrument is arranged in described expansion link, and one end is connected with rubber bulb by connecting rope, described connection rope runs through described expansion link, described float device is movably arranged on connection rope, and described expansion link is threaded connection by some sleeve pipes and forms.This utility model simple in construction, easy to use, it is possible to achieve with the quick measurement of the flow rate of water flow of two aspects at current under the different far and near distance in distance bank, river at different water depth.
Description
Technical field
This utility model relates to a kind of flow rate of water flow measurement apparatus, is specifically related to a kind of bar thread ball measurement in a closed series flow rate of water flow
Calculating instrument.
Background technology
At present, measuring river water speed and be difficult to accomplish to investigate water velocity at different water depth, also being difficult to reach pre-even if measuring
The accuracy of phase, additionally, due to the multiformity that riverbed is complicated, under the difference far and near distance of distance bank, river, is difficulty with distance
The measurement problem of river flow under the difference far and near distance of riverbank.
Utility model content
For solving the problems referred to above, this utility model provides a kind of bar thread ball measurement in a closed series flow rate of water flow calculating instrument, structure
Simply, easy to use, it is possible to achieve with two aspects at current under the different far and near distance in distance bank, river at different water depth
The quick measurement of flow rate of water flow.
For achieving the above object, the technical scheme that this utility model is taked is:
Bar thread ball measurement in a closed series flow rate of water flow calculating instrument, including pulley calculating instrument (that is: of band counting assembly be used for around
The rotating shaft of line), expansion link, float device and rubber bulb, described pulley calculating instrument is arranged in described expansion link, and one end is passed through
Connecting rope to be connected with rubber bulb, described connection rope runs through described expansion link, and described float device is movably arranged on connection rope, institute
State expansion link to be threaded connection by some sleeve pipes and form.
As preferably, described float device is arranged between rubber bulb and expansion link, and is positioned at outside expansion link.
As preferably, described float device uses rubber bulb.
This utility model has the advantages that
Simple in construction, easy to use, it is possible to achieve with current under the different far and near distance in distance bank, river at different water depth
The quick measurement of the flow rate of water flow of two aspects in place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearer, below in conjunction with embodiment, this utility model is entered
Row further describes.Should be appreciated that specific embodiment described herein, and need not only in order to explain this utility model
In limiting this utility model.
As it is shown in figure 1, this utility model embodiment provides a kind of bar thread ball measurement in a closed series flow rate of water flow calculating instrument, including
Pulley calculating instrument 1 (that is: of band counting assembly is used for the rotating shaft of coiling), expansion link 2, float device 4 and rubber bulb 5, institute
Stating pulley calculating instrument 1 to be arranged in described expansion link 2, and one end is connected with rubber bulb 5 by connecting rope 3, the described rope 3 that connects passes through
Wearing described expansion link 2, described float device 4 is movably arranged on connection rope 3, and described expansion link 2 is passed through screw thread by some sleeve pipes
It is formed by connecting.
Described float device 4 is arranged between rubber bulb 5 and expansion link 2, and is positioned at outside expansion link 2.
Described float device 4 uses rubber bulb.
Originally it is embodied as pulley calculating instrument and can record the length of the line that the rotation measuring current by pulley pull, and
Time time pulled the line of unit length in time starting to measure to current.Rubber bulb 5 is for can sink at different water depth
Rubber bulb, the rubber bulb of different size and quality can be selected according to different rivers；Flotation gear 4 is for can enter with up-down adjustment
The rubber bulb of water depth, thus realize different water depth and measure the regulation effect of process.
Originally the principle being embodied as is: use unit length L of current pulls wire to be a certain degree of depth divided by measuring time T
The flow velocity K of current under the flow velocity of current or distance bank different distance.Computing formula is: the flow velocity K=current of current pull
Unit length L/ of line measures time T.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
