Description

A kind of pressure content gauge

Technical field

The utility model relates to level measuring technical field, specifically relates to a kind of pressure content gauge.

Background technology

Along with the development of producing, the places such as water factory, sweat treatment plant, pond of high building, well, mine, oil sump, reservoir and river course all need to carry out horizontal survey, pressure content gauge is a kind of conventional survey instrument, export by the pressure of hydrostatic being converted into electric signal, and on instrument, show convenient observation.

Probe is directly arranged in water by general pressure content gauge, is wired in outside display device, but in water, there is the impurity such as a large amount of silt, easily blocked by probe in long-term use procedure.

Therefore for a person skilled in the art, how designing a kind of pressure content gauge that can prevent probe from blocking, is the current technical issues that need to address.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of pressure content gauge, comprises transmitter, air guide cable and gauging table, the outer cover fitted tube body of described transmitter; Be rotatably provided in the screen pack of the inside of described cylindrical shell, described filtration net cover is contained in the outside of described transmitter; On the inwall of described cylindrical shell arrange can with the scraping article of described screen pack wall contacts.

Alternatively, one end of described cylindrical shell has opening.

Alternatively, described scraping article arranges three, is evenly distributed on the inwall of described cylindrical shell.

Alternatively, described scraping article is silica gel scraping article.

Alternatively, the outer wall of described screen pack is arranged the handle for rotating.

Alternatively, the xsect of described scraping article is T font, is arranged in the groove that on described cylinder inboard wall, correspondence position is offered.

Pressure content gauge provided by the utility model has been set with cylindrical shell in the outside of transmitter, screen pack is provided with in the inside of cylindrical shell, filtration net cover is contained in the outside of transmitter, screen pack can at the internal rotating of cylindrical shell, and the inwall of cylindrical shell is provided with scraping article, scraping article can with the external contact of screen pack.Measured water can first carry out filtering the probe place being transported to transmitter again by screen pack, effectively prevent the appearance of transmitter congestion situations, screen pack can be placed after screen pack gets clogged, screen pack is contacted with scraping article, the impurity being deposited to screen pack outer wall can be wiped off, the water-pressure survey of transmitter is not affected, and can remove in time when impurity is too much, when avoiding Long-Time Service, transmitter is blocked.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

The structural representation of the pressure content gauge that Fig. 1 provides for the utility model;

Fig. 2 is the assembly structure figure of all parts.

Wherein:

Transmitter 1, cylindrical shell 11, screen pack 12, scraping article 13, air guide cable 2, gauging table 3.

Embodiment

Core of the present utility model is to provide a kind of pressure content gauge, can avoid being blocked by the probe of transmitter in Long-Time Service process.

In order to make those skilled in the art understand technical scheme provided by the utility model better, the embodiment concrete below in conjunction with accompanying drawing is described in detail the pressure content gauge that the utility model provides.

As shown in Figure 1, be the structural representation of pressure content gauge; Fig. 2 is the assembly structure figure of all parts.This pressure content gauge specifically includes transmitter 1, air guide cable 2 and gauging table 3, transmitter 1 is placed into below liquid level, for experiencing liquid hydraulic pressure, transmitter 1 is connected by air guide cable 2 with gauging table 3, the probe of transmitter 1 experiences fluid pressure, pressure signal is converted to electric signal, and is sent in gauging table 3 by air guide cable 2, data are shown.Transmitter 1 is directly placed in water by the metering system of general employing, but there is the impurity such as a large amount of silt in water, easily deposits to generation transmitter 1 causing block.

The utility model is at the outer cover fitted tube body 11 of transmitter 1, between cylindrical shell 11 and transmitter 1, there is certain space, cylindrical shell 11 is not closed structure, the current of cylindrical shell 11 to outside do not hinder, do not affect the turnover of current, cylindrical shell 11 can be the structure offering multiple perforate, and the structure that the utility model provides arranges opening in one end of cylindrical shell 11, the impact that the flowing that can reduce water is measured transmitter, is wrapped in whole transmitter 1 in the internal cavity of cylindrical shell 11.

At the internal rotating of cylindrical shell 11, screen pack 12 is set, screen pack 12 can rotate along the axis of self in the inside of cylindrical shell 11, and screen pack 12 is sleeved on the outside of transmitter 1, namely transmitter 1, screen pack 12, cylindrical shell 11 set gradually from inside to outside, do not fix between screen pack 12 and transmitter 1, can relatively rotate between the two.The inwall of cylindrical shell 11 is also provided with scraping article 13, and scraping article 13 is relative with cylindrical shell 11 fixing, and can contact with the outer wall of screen pack 12, can play the effect scraped when screen pack 12 rotates to screen pack 12.Transmitter 1 wraps up by screen pack 12 completely, can contact with external water stream by tiny grid, impurity in current can be filtered net 13 and adsorbs and be deposited on screen pack 12, make transmitter 1 body and unaffected, scraping article 13 can be contacted with the outer wall of screen pack 12 by rotating screen pack 12 when the sediment on screen pack 12 is more, sediment on screen pack 12 outer wall is removed, reach the effect of scale removal, also transmitter 1 can not be made to block in long-term use procedure, cleaning course is quick and convenient.

The scraping article 13 provided in the utility model adopts frictioning material, and silica gel is soft and have toughness, the impurity of screen pack 12 outer wall can be wiped off and can not cause damage to screen pack 12, more convenient during use.

Particularly, in the utility model, three silica gel scraping articles are set on the inwall of a cylindrical shell 11, ensure to play better scraping effect to screen pack 12, scrape cleaner, certainly, these quantitative settings are not limited to three, also can carry out corresponding change according to demand.

Sliver transvers section of scraping set in the utility model is T font structure, can be inserted on cylindrical shell 11 inwall offers in ground groove, can be convenient for changing in use, if removing can be dismantled in time after scraping article 11 also having gathered the impurity of precipitation, facilitate follow-up maintaining.

The outer wall of screen pack 12 also arranges handle, and grip when conveniently rotating through filter screen 12, handle can be the form that rotating shaft adds handle, and be convenient to rotate, also can be set to other corresponding constructions, the utility model does not limit at this.
