Description

A kind of float type level meter

Technical field

This utility model relates to a kind of level measurement device, particularly relates to a kind of float type level meter.

Background technology

River, irrigation canals and ditches etc. are carried out water level test when, typically take directly on river or trench sidewall, directly to arrange level scale, then read water level in real time by this level scale.But, said method can produce bigger reading error in the case of water level fluctuation is relatively big, and due to human eyes structure, if not being just read out graduation mark, can produce bigger reading error equally.

Additionally, when same river or irrigation canals and ditches close positions are carried out multiple spot sensed water level, cannot be aggregated in same display device by the waterlevel data of each point, this has resulted in cannot detect multi-point water level in real time simultaneously, has had a strong impact on collection and the research of waterlevel data.

Utility model content

Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of float type level meter, and water level information can be shown on instrumental panel by real time.

For achieving the above object, this utility model provides a kind of float type level meter, including measuring pipe, described measurement pipe top is connected with power pipe by connecting leg, in described power pipe, power piston is installed, described power piston is connected with tooth bar one end by push-pull bar, and described tooth bar engages with arc half gear being arranged on instruction pin one end；Described instruction pin is hinged with water gauge by the first hinge, and described water gauge is indicating the pin adjacent one end away from arc half gear to be provided with level scale, can read waterlevel data by instruction in real time for the level scale answered；

Being provided with float in the described inner tube measuring pipe, described float is spheroid；Described float is connected with thrust piston by connecting rod.

As further improvement of the utility model, described water gauge being provided with chute, described chute assembles with slide block, and described slide block is fixed on tooth bar；Described slide block low order end is connected with chute wall by spring.

As further improvement of the utility model, described connecting rod is connected one end and is provided with connection cambered surface with float.

As further improvement of the utility model, it is that diameter is by the Rotary-table gradually diminished to coupling part with thrust piston end that described connecting rod is connected one end with thrust piston.

As further improvement of the utility model, described measure pipe diameter of inner pipe should be at least power pipe diameter times.

As further improvement of the utility model, between thrust piston and power piston, it is filled with the gas of certain pressure.

As further improvement of the utility model, described float is hollow ball.

The beneficial effects of the utility model are: this utility model is capable of showing on water gauge waterlevel data in real time, when carrying out multiple spot and detecting simultaneously, the water gauge of the detection of multiple spot can be integrated or puts together, which achieves and detect while multi-point water level.

It addition, measuring accuracy of the present utility model compared with by existing water level bar, river course sidewall arrange level scale measure much higher, it is possible to for water level research bring more preferable data refer.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model a kind of float type level meter detailed description of the invention.

Fig. 2 is the enlarged drawing of A in Fig. 1.

Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

See Fig. 1 to Fig. 2, a kind of float type level meter, including measuring pipe 1, described measurement pipe 1 top is connected with power pipe 6 by connecting leg 5, in described power pipe 6, power piston 7 is installed, described power piston 7 is connected with tooth bar 03 one end by push-pull bar 8, and described tooth bar 03 engages with arc half gear 04 being arranged on instruction pin 9 one end；Described instruction pin 9 is hinged with water gauge 01 by the first hinge 02, and described water gauge 02 is indicating the pin 9 adjacent one end away from arc half gear 04 to be provided with level scale, can read waterlevel data in real time by the level scale of instruction pin 9 correspondence；

Being provided with float 2 in the described inner tube 11 measuring pipe 1, described float 2 is spheroid；

Described float 2 is connected with thrust piston 4 by connecting rod 3.

During use, being first placed into, by measuring pipe 1, the position needing to measure water level, contacting with the bottom bottom pipe until measuring.Now, by hydraulic pressure and the differential pressure action measured in pipe 1, float 2 can promote thrust piston 4 to move upward, when thrust piston 4 moves upward, owing to measuring pipe 1, connecting leg 5, power pipe 6 is all to seal, thrust piston 4 will carry out propulsion power piston 7 to left movement by the air measured in pipe 1 of bronze drum compression, power piston 7 is when left movement, tooth bar 03 will be promoted to left movement by push-pull bar 8, described tooth bar 03 drives again arc half gear 04 engaged to rotate, described arc half gear 04 will drive instruction pin 9 to rotate centered by the first hinge 02 when rotating, correspondence position now by instruction pin 9 with level scale just can read waterlevel data.

When the water level descends, this utility model of the present utility model can carry out reverse operating according to above-mentioned action, the most just can be read out the change of water level by instruction pin 9 in real time, and degree of accuracy can be more much higher than directly arranging level scale on river course sidewall.

Further, during in order to prevent water level decreasing, power piston can not provide enough power to move for tooth bar, can arrange chute 011 on water gauge 02, and described chute 011 assembles with slide block 031, and described slide block 031 is fixed on tooth bar 03；Described slide block 031 low order end is connected with chute 011 sidewall by spring 05.When push-pull bar 8 promotes tooth bar to move right, can first overcome the elastic force of spring；When the water level descends, push-pull bar 8 can be to left movement, and now spring 05 can provide augmented thrust to the left for tooth bar, to help tooth bar to be moved to the left.

Further, in order to make the buoyancy at float 2 preferably transmit to thrust piston 4, one end can be connected at connecting rod 3 with float 2 and connection cambered surface 32 is set, described connection cambered surface 32 can increase the contact area of float 2 and connecting rod 3, prevents the pressure between float 2 and connecting rod 3 excessive and makes connecting rod 32 thrust in float 2；

Described connecting rod 3 is connected one end and is set to diameter by the Rotary-table gradually diminished to coupling part 31 with thrust piston end with thrust piston 4, so the buoyancy of float can compare and is uniformly transmitted on thrust piston 4, make thrust piston 4 more be smoothly moved.

Further, in order to make measurement pipe 1 provide the most enough power for power piston 7, described measure pipe 1 diameter of inner pipe and should be at least 4 times of power pipe 6 diameter.

Further, in order to make power piston 7 react quick, the gas of certain pressure can be filled with between thrust piston 4 and power piston 7.

This utility model is capable of showing on water gauge waterlevel data in real time, when carrying out multiple spot and detecting simultaneously, the water gauge of the detection of multiple spot can be integrated or be put together, and which achieves and detects while multi-point water level.

Preferred embodiment of the present utility model described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should be in the protection domain being defined in the patent claims.
