Flow rate calculation, water rate trade settlement, energy measurement and the control of industrial or agricultural water utilizing process etc. are responsible for particularly important role.
Before water meter dispatches from the factory, it is necessary to whether accurate examine and determine its reading.
At present, Publication No. CN105865589A Chinese patent discloses a kind of intelligent full flow point full-automatic water meter
Calibration equipment, it includes water piping system and water meter clamping device；The water tank of water piping system and water pump, filter and main water supply
Pipe is sequentially communicated, and main-supply connects with total outlet pipe；Branch water inlet pipe, piston hydraulic pressure meter and branch are parallel with main-supply
Outlet pipe；Total outlet pipe outlet connects with high-precision water outlet tube inlet, low precision water outlet tube inlet and pressure release water outlet tube inlet respectively
Logical, high-precision outlet pipe outlet connects through inverted U pipe with water tank；Low precision outlet pipe connects through L-type pipe with splitter inlet, point
Stream device first outlet is connected with graduated cylinder, and graduated cylinder is shelved on scale.
For saving water resource, environmental protection, after water was entered water meter, can enter in reserve tank, then entered by pump
Enter into water piping system, realize that water reuses.
This intelligent full flow point full-automatic water meter calibration equipment is simple in construction, but when in use, water meter is placed on
On fixture block, fixture block is slidably connected on the guide bar, water meter is supported by fixture block, due to that can produce one between guide rod and fixture block
Quantitative incrustation scale so that mobile frictional force is larger on the guide bar for fixture block, and it is more inconvenient that worker moves fixture block.
The content of the invention
In view of the deficienciess of the prior art, the invention reside in a kind of water meter detection means is provided, by pressing drive rod,
Clamping plate is contradicted or is separated with slide plate, reach the purpose of fixture block easy to remove.
To achieve the above object, the invention provides following technical scheme：A kind of water meter detection means, including storage tank,
Support frame, slide plate is connected with along the length direction of support frame, is connected with described support frame and enters for what is be connected with storage tank
Water seat and effluent seat, the fixture block between water-logged base and effluent seat, described fixture block bag are slidably connected on described slide plate
Connecting portion and the sealing for being connected with water meter are included, clamping plate is connected with described connecting portion, is set on described connecting portion
There is drive rod, described drive rod is connected by transmission component with clamping plate, and transmission component is connected on connecting portion, described driving
Length direction of the bar along itself is moved through the transmission component driving clamping plate and contradicts or separated with slide plate, the clamping plate with slide plate
Slide plate both sides are respectively placed in connecting portion.
By using above-mentioned technical proposal, when needing to move fixture block, by pressing drive rod, driven by transmission component
Clamping plate is moved, and clamping plate is separated with slide plate, now, fixture block is supported by connecting portion, can be easy to move fixture block,
After sealing is connected with water meter, drive rod is pressed again, drive rod is driven clamping plate toward close to slide plate by transmission component
Direction is moved, and the connecting portion for being placed on slide plate both sides contradicts with slide plate simultaneously with clamping plate, you can positions fixture block；By fixture block in cunning
When positioning on plate, it is not easy to produce larger difference in height on slide plate, so that current can be more gentle when passing through water meter so that
Reading is more accurate.
The present invention is further arranged to：Described transmission component includes positioning seat, the first sliding block, the second sliding block, bootstrap block
And elastic component, described positioning seat are fixed on connecting portion, the first described sliding block, which is connected and is slidably connected to drive rod, to be determined
In the seat of position, the second described sliding block is slidably connected in positioning seat and is connected with clamping plate, and the first described sliding block is back to drive rod

So that the second sliding block 73 produces rotation in mounting hole 511 so that bootstrap block 74 is corresponding with the 3rd inclined-plane 712, unclamps drive rod 6
Afterwards, acted on by the elastic force of elastic component 75, by bootstrap block 74 on the 3rd inclined-plane 712, now, clamping plate 9 separates with slide plate 11,
So as to fixture block 5 easy to remove；When pressing drive rod 6 again, similarly, the second sliding block 73 produces after being stretched out from positioning seat 71
The rotation of raw certain angle, now, bootstrap block 74 is corresponding with chute 711, after unclamping drive rod 6, passes through the elastic force of elastic component 75
Effect, the second sliding block 73 is promoted to be moved toward close to the direction of the first sliding block 72, bootstrap block 74 is placed in chute 711 and along chute
711 move toward close to the direction of the first sliding blocks 72, and clamping plate 9 moves with the movement of the second sliding block 73, and with slide plate 11 back to
The side of connecting portion 51 contradicts, and caused frictional force can be such that fixture block 5 is positioned on slide plate 11.
After water meter has been detected, a part of water can be remained in water meter, during water meter is removed from fixture block 5, water
It can fall on support frame 1.Multiple apopores are offered on support frame 1, water storage box, support frame 1 are placed in the lower section of support frame 1
On water fallen into by apopore in water storage box.The one end for unloading water pipe connects with water storage box, and the other end connects with storage part 22, leads to
The effect of gravity is crossed, the water in water storage box is incorporated into storage part 22.Realize recycling for water, saving water resource.
In summary, in use, setting a fixture block 5 between two neighboring water meter, Hydraulic Cylinder water inlet pipe 31 is passed through
Moved toward close to the direction of water meter, and be set in the water inlet end of water meter, and further water meter is pressed so that water meter and fixture block 5
Between there is high-seal, then press drive rod 6 and position fixture block 5, startup water pump easy to operate, by water from the note of water inlet pipe 31
Enter into water meter, stop after water meter walks a period of time, record initial value；Then the valve in water storage part 21 is closed, starts water
Pump, water is entered in water meter from water-logged base 3, and exported to from water meter in effluent seat 4, then enter water storage from effluent seat 4
In portion 21, the water level in water storage part 21 is shown in graduated cylinder 23 in real time, after certain water level is reached, is stopped water pump, is recorded water
The end value of table, last value is subtracted into initial value, is exactly water-carrying capacity, compared with the water in water storage part 21, you can show that the water meter is
No standard.
