Abstract
The utility model discloses a level gauge of water conservancy is exclusively used in, its characterized in that: include casing, circuit board and follow down up in proper order that fixed mounting preventing on the circuit board blocks up sample part, differential pressure sensor spare, changer, lightning protection device and air guide cable, circuit board fixed mounting is inside the casing. The utility model has the advantages of: the utility model discloses a casing adopts stainless steel, has good corrosion resistance, the utility model discloses a differential pressure sensor spare is installed in stainless steel shell's bottom, has increased effectual induced surface and has amassed, has avoided piling up of silt, the utility model discloses an inside has still set up lightning protection device, has reduced the fault rate of round thunderbolt, has prolonged life.
Description
Technical field
The utility model relates to liquid level gauge field, is specifically related to a kind of liquid level gauge being exclusively used in water conservancy.
Background technology
Water-level gauge is the key instrument to water level real-time monitorings such as river, reservoir, lakes, and it ensures key water control project safety, plays forewarning function to disasters such as possible floods, and water level monitoring value, concerning extremely important people, more has far-reaching influence to productive life.Water-level gauge is as the key instrument of water level monitoring, and its metering system has radar, ultrasound wave, cable formula and pressure type etc.; Because in river course, floating thing is more, radar, ultrasound wave, run into foreign material and often can affect measurement, and expensive; Cable formula because level fluctuation, kickboard are stuck, draw over to one's side skidding, the reason such as complicated is installed also is restricted in part use occasion.Pressure type because easy for installation, principle is simple, the reason such as economical and practical is widely applied, but its easy blocking, the reason such as to be struck by lightning, later maintenance is more.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, now provides a kind of lightning protection, anti-blocking pressure type is exclusively used in the liquid level gauge of water conservancy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of liquid level gauge being exclusively used in water conservancy, and its innovative point is: the anti-blocking sampled part, differential pressure pick-up part, transmitter, lightning protection component and the air guide cable that comprise Stainless Steel Shell, circuit board and fixedly mount from the bottom up successively on circuit boards; Described circuit board is fixedly mounted on Stainless Steel Shell inside.
Further, the structure of described Stainless Steel Shell is hollow cylinder, and described differential pressure pick-up part is positioned at the bottom of Stainless Steel Shell.
Further, described air guide cable is made up of wireway and electric wire two parts.
The beneficial effects of the utility model are as follows:
(1) housing of the present utility model is Stainless Steel Shell, has good corrosion resistivity.
(2) differential pressure pick-up part of the present utility model is installed on the bottom of Stainless Steel Shell, adds effective induction area, avoids the accumulation of mud.
(3) inside of the present utility model is also provided with lightning protection component, decreases thunderstruck failure rate, extends serviceable life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this instructions can understand other advantages of the present utility model and effect easily.
Be illustrated in figure 1 structural representation of the present utility model, be exclusively used in a liquid level gauge for water conservancy, the anti-blocking sampled part 1, differential pressure pick-up part 2, transmitter 3, lightning protection component 4 and the air guide cable 5 that comprise Stainless Steel Shell 6, circuit board and fixedly mount from the bottom up successively on circuit boards; It is inner that circuit board is fixedly mounted on Stainless Steel Shell 6, and the structure of Stainless Steel Shell 6 is hollow cylinder, and differential pressure pick-up part 2 is positioned at the bottom of Stainless Steel Shell 6; Air guide cable 5 is made up of wireway and electric wire two parts.
Wireway in air guide cable 5 of the present utility model and atmospheric pressure are linked up, to the side of differential pressure pick-up part 2, compare with opposite side level pressure, output voltage signal, through the signal of lightning protection component 4 and transmitter 3 stable output, the height of reaction liquid level, by lightning protection component 4 and signals collecting and treatment circuit integration, lightning protection component 4 and transmitter 3 earthing of casing.
The utility model is provided with lightning protection component 4 in inside, can stablize use, decrease thunderstruck failure rate, extend serviceable life under the physical environments such as severe river course, lake; Optimize structure simultaneously, avoid the blocking of mud, Detection results is stablized simultaneously.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
Claims (3)
