Description

Portable field flow measurement triangular weir

Technical Field

The utility model belongs to geology reconnaissance engineering field, concretely relates to a triangle weir structure for flow measurement is carried out in field.

Background

The existing triangular weir structure for flow measurement is too simple and crude, is inconvenient to operate and has large measurement error under the condition of limited field conditions, and is embodied in the following aspects: (1) and the handle is not available, so that the carrying is inconvenient. (2) Whether the installation is horizontal is judged only by human perception. If the triangular weir is installed and inclined, the reading error is large, and the measurement is inaccurate. (3) The scale is not arranged, the reading is manually measured on the side edge by a worker with a steel ruler, and the error is large. (4) When the device works in the field, the device cannot be quickly installed and fixed. The stones and the soil can be picked up only by manpower and are stacked on two sides of the triangular weir for stabilization, and the triangular weir is easy to incline or collapse.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a convenient to carry, measure accurate, install fast and stable's triangle weir.

Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a portable open-air flow measurement triangle weir, includes bilateral symmetry and has the triangle weir body of triangle-shaped delivery port, there is the handle top of triangle weir body through the screw mounting, a spirit level is respectively installed to the left and right sides of handle, respectively is provided with a recess in the left and right sides of triangle weir body bottom, and the articulated nail of inserting of installing in every recess, insert the nail and can rotate to the open mode of tip down around the pin joint, also can rotate to the hidden state in the recess around the pin joint, at least one side of triangle-shaped delivery port is provided with the scale mark.

Preferably, the handle and the triangular weir body are equal in width, the handle is formed by stamping and bending a sheet metal part, an upward arched part is arranged in the middle of the handle, and the arched part corresponds to the triangular water outlet and is equal in width. The handle adopts the sheet metal component to buckle and forms, is convenient for install on the triangle weir body through the screw, and the handle middle part sets up the hunch-up portion that is the same width with the triangle-shaped delivery port, vacates more spaces for portable pull handle.

Preferably, each groove is internally provided with an elastic plastic card, the elastic plastic card is inserted into the groove to realize fixation, the elastic plastic card is provided with a restraint hanging ring, the diameter of the restraint hanging ring is matched with that of the inserted nail, and the restraint hanging ring is provided with a notch for the inserted nail to enter. The special elastic plastic card is adopted, the installation is convenient and quick, and the smooth passing in and out of the inserted nail is facilitated by the elasticity of the plastic slot.

Preferably, the two sides of the triangular water outlet are provided with scale marks, so that the staff on the two sides can observe conveniently.

The using method comprises the following steps: when the triangular weir is used in field work, the inserting nails below the triangular weir body are firstly pulled out of the grooves, and the top of the triangular weir body is lightly pressed by hands, so that the triangular weir can be inserted into soil or gravel to be stable. And a level gauge above the leveling ensures that the triangular weir is in a horizontal state. After the water flow is stable, the reading can be carried out on the graduated scale. After the triangular weir is used, the triangular weir is taken down, the inserting nail is placed in the groove in a rotating mode, and the inserting nail can be taken away by holding the handle. If the ground is in bedrock or is too hard, the inserting nail can not be inserted underground, the inserting nail does not need to be pulled out, at the moment, a triangular weir needs to be fixed by riprap and soil, and the reading is carried out after leveling and water flow is stable.

The utility model has the advantages that: add the handle and make things convenient for when field survey hand-on the basis of current triangle weir, add the spirit level and ensure to be in the horizontality after the triangle weir installation, add the use or the carrying that can accomodate the plug pin in the recess and satisfy different occasions, add the scale mark, need not be equipped with the scale in addition and measure. The processing is simple and the cost is low; the reading is accurate, particularly when the flow rate is small, the reading error is reduced, and the hydrogeological parameters can be accurately calculated; is convenient to carry and install.

Detailed Description

The invention will be further described by way of examples with reference to the accompanying drawings:

referring to fig. 1-2, a portable field flow measuring triangular weir mainly comprises a triangular weir body 1, a handle 2, a level 3, an inserted nail 4 and an elastic plastic card 5.

The triangular weir body 1 is bilaterally symmetrical and is provided with a triangular water outlet 1a, and the triangular water outlet 1a is in an inverted isosceles right triangle shape with a large upper part and a small lower part, namely the included angle of a triangular opening is 90 degrees.

The handle 2 is installed through the screw in the top of triangle weir body 1, conveniently carries. Preferably, the handle 2 and the triangular weir body 1 are equal in width, the handle 2 is formed by stamping and bending a sheet metal part, an upward arched part 2a is arranged in the middle of the handle 2, and the arched part 2a corresponds to the triangular water outlet 1a in position and is equal in width.
