Abstract
The utility model relates to a detection device, especially, relate to a current surveying device, including base, wall body and sensor, the pedestal mounting is in the channel bottom, and the wall body vertical fixation is on the base, and the wall body includes the first terminal surface relative with water flow direction, wall, back to water flow direction's second terminal surface and wall crown, and sensor settings is on the wall. The utility model provides a current surveying device installs in the middle part of channel, and the base is firm, and safety can record the velocity of flow of real water, can measure for the open channel and obtain more accurate data.
Description
Technical field
This utility model is related to a kind of current surveying device, more particularly, to a kind of current surveying device being arranged in the middle part of channel.
Background technology
Current flux sensor is typically all arranged in channel bottom or side slope, and both mounting means all have drawback.As
Fruit is arranged on channel bottom, make how all to there is a problem of to cover in mud, time length transducer sensitivity
Decline, even damage.If being arranged on channel side slopes, for wider channel, current at side slope due to big by resistance,
The flow velocity of water can be more much lower than in the middle part of channel, even the flow-speed measurement of side slope less than.
Content of the invention
This utility model is easily covered by mud and is arranged on side slope current to solve sensor and being arranged on channel bottom
A kind of the problems such as measurement that speed slows down and causes is inaccurate, there is provided new current surveying device.
This utility model for the technical scheme of the offer that solves the above problems is：A kind of current surveying device, including base, body of wall and
Sensor, in channel bottom, described wall body vertical is fixed on base described floor installation, and described body of wall includes and water
The relative first end face in stream direction, metope, back to the second end face of water (flow) direction and wall top, described sensor is arranged on metope
On.
In order to prevent the covering of channel bottom mud, described sensor is the 1/3 of metope height with the distance of base.
In order to ensure current when the sensor recovered steadily, described sensor is more than with the distance of first end face
Sensor and the distance of second end face.
In order to increase the stability of device further, described base structure T-shaped with body of wall is fixedly connected.
Further, as a kind of specific version, described metope is parallel with water (flow) direction；Described metope with
Channel bottom is vertical；Described body of wall is arranged on the center position of channel；Described wall top is concordant with channel top.
Recovered steady during sensor in order to be further ensured that current flow through, described metope length is 5 meters,
The beneficial effects of the utility model are：1st, setting base contributes to current surveying device is stabilized in channel.2nd, sense
Device is arranged on highly to be located apart from base 1/3 metope, can prevent the covering of mud.3rd, metope length is set to 5 meters, and will pass
Sensor is arranged at first end face 1/2 metope length it is ensured that having recovered steady when current are through sensor.4th, by part
Base embeds channel bottom and contributes to consolidating current surveying device further, and anti-locking apparatus are washed away by current.
Current surveying device is installed on the middle part in river course, and base is firm, and safety can record the flow velocity of the most real water, permissible
Obtain more accurately data for open channel measurement.

Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in more detail.It is to be understood that this
The protection domain of utility model is not limited by specific embodiment.
A kind of current surveying device includes base 1, body of wall 2 and sensor 3, and body of wall 2 is fixedly connected perpendicular to base 1, and body of wall 2 wraps
Include metope 4, first end face 5, second end face 6 and wall top 7, metope 4 is perpendicular to channel bottom and parallel with water (flow) direction, first end
Face 5 is relative with water (flow) direction, and second end face 6 is back to water (flow) direction；Sensor 3 is fixed on metope 4 at base 1/3 height,
And the distance of sensor 3 and first end face 5 is more than the distance of sensor 3 and second end face 6.When current flow through body of wall 2, flow first
Through first end face 5, it is then passed through sensor 3 and second end face 6.Base 1 and body of wall 4 are cuboid or cube structure, bottom
The lower surface of seat 1 embeds in channel bottom, and the upper surface of base 1 is contacted with body of wall 2 and current, and upper surface area is more than and wall
The contact area of body 2.Wall top 7 is concordant with channel top 8.Body of wall 2 is arranged on the center position of channel, and metope 4 length is 5m.
The making of current surveying device and installation process:
In flow measurement point, need first to clear up the mud depositing in channel, cleaning completes smooth base area, then according to
Drawing dimensional requirement uses φ 10 reinforcement constitution skeleton, rear fixed form, casting concrete.Mould is removed after concrete setting
Plate, install sensor 3, you can commissioning device comes into operation.
