The diameter of the floating ball is 80 to 120mm; therefore, the sampling port is kept above the liquid level by specified distance all the time and is not immersed; and the mode of the multiple guide rods can prevent the floating balls from rotating and being blocked by winding of the soft pipe, therefore, a sampling system can carry out reliable extraction and detection to gas overflowing the liquid level.
Description
Technical field
The present invention relates to a kind of sampling apparatus, especially a kind of floating ball device that is used for gas sampling.
Background technology
In existing real work, some gas sampling assembly is simple, outmoded, usually because in a single day residing environment more special, narrow and small and can't the installation and measuring instrument such as the space occurring, or exist negative pressure to make instrument sampling situation of difficult, common gas sampling assembly just occurs not knowing how to gather gas, especially at the gas that overflows of liquid level, sampled point must remain on certain distance on the liquid level, or in the liquid level situation concordant with ground level, as at sewage draining exit, sewer and groove jar etc., your difficulty that extracts so reliably and detect is bigger, do not know to set about, because the gas sampling floating ball device adopts single guide rod mode, be difficult to effectively prevent the rotation of ball float sometimes from which, the appearance flexible pipe is wrapped in the phenomenon on the guide rod, thereby make ball float stuck, finally cause thief hatch to be flooded, produce serious consequence by liquid level because of the winding of flexible pipe.Such as; in existing patent documentation; application number is 200620151411.1; the applying date be on November 20th, 2006, Granted publication number for CN200968909, the day for announcing be on October 31st, 2007, patentee the pollution source foul gas sampling thief for Tianjin City Environment Protection Science Inst., the utility model relates to a kind of gas collecting device.It can repeatedly clean sampling container before sampling, has improved the really degree of institute's collected specimens; It is big or have a sampling operation of the sample gas of dust to go for being in negative pressure or moisture percentage; The complete machine lighter weight is easy to carry, and does not have broken problem.It comprises sampling thief, sampling bucket, sampling rifle; Sampling thief comprises housing, minipump-micro air pump, four-way operation valve, motor, power supply; Housing is provided with the power gas interface; The sampling bucket comprises staving and sealing bung; On staving, be provided with power gas interface and sampling interface, place sampler bag in the staving.The sampling rifle is tubular.The power gas interface of the power gas interface of sampling thief and sampling bucket is with pipeline is connected, the sample outlet side socket connection of the sampling interface and the rifle of sampling of bucket.It is used for the collection of the pollution source gaseous sample of stench or gas with foreign flavor intensity and concentration determination, but this utility model is narrowless and small and can't the installation and measuring instrument or exist negative pressure to make under the instrument sampling situation of difficult how this solves at the space occurring, especially at the gas that overflows of liquid level, sampled point must remain on certain distance on the liquid level, or in the liquid level situation concordant with ground level, do not know to set about, gather into a difficult problem from which.
Summary of the invention
It is often stuck from transferring because of ball float to the present invention is directed to the floating ball device that exists in the prior art, easily flooded at extreme environment down-sampling mouth by liquid level, be difficult to liquid level is overflowed the problem that gas extracts reliably and detects, a kind of floating ball device that is used for gas sampling is provided.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of floating ball device that is used for gas sampling, comprise cover plate, guide rod, ball float, the ball float fixed head, thief hatch and flexible pipe, described cover plate is installed in the peak in orientation, gas sampling point place, described flexible pipe one end is connected with thief hatch, the flexible pipe other end stretches out the cover plate top, thief hatch is fixed on the below of cover plate by a support bar, the support bar other end is fixed on the foraminate ball float fixed head, it is fixing on the cover board that described guide rod passes aperture, ball float is installed on the ball float fixed head that can fluctuate along guide rod, described guide rod has the 2-3 root, described ball float is 3-5, the described ball float fixed head that is installed in the ball float top has the 1-3 piece, and the ball float fixed head that is installed in the ball float below has the 1-2 piece.This structure helps effectively preventing the rotation of ball float; flexible pipe is wrapped on the guide rod; make the ball float can be not stuck because of the winding of flexible pipe, the protection thief hatch not be flooded by liquid level under the extreme environment situation, and sampling system can be overflowed gas to liquid level and be extracted reliably and detect.
As preferably, described guide rod has two, and ball float is three, and the ball float fixed head that is installed in the ball float top has two, and the ball float fixed head that is installed in the ball float below has one, and two ball float fixed heads of ball float top are bolted to connection.This structure is beneficial to the rotation that effectively prevents ball float most and causes flexible pipe to be wrapped on the guide rod and stuck, can protect thief hatch not flooded by liquid level under extreme ambient conditions, and sampling system can be overflowed gas to liquid level and be extracted reliably and detect.
As preferably, triangular in shape or the square or pentagon of described ball float fixed head.This structure is beneficial to ball float most and is securely fixed on the ball float fixed head.
As preferably, the diameter of described ball float is 80-120mm.This structure helps increasing the buoyancy of ball float, is beneficial to collection gas.
As preferably, the diameter of described ball float is 100mm.This structure is beneficial to the buoyancy that increases ball float most, is beneficial to collection gas.
As preferably, there is a raised structures that can hold thief hatch the centre of described cover plate.This structure helps thief hatch and remains on the liquid level with the distance of regulation all the time, even and also can not flood thief hatch under the liquid level situation concordant with ground level.
As preferably, described raised structures is arch or arc.This structure is beneficial to thief hatch most and remains on the liquid level with the distance of regulation all the time, even and also can not flood thief hatch under the liquid level situation concordant with ground level.
According to technical scheme of the present invention; thief hatch remains on the liquid level with the distance of regulation all the time; even and under the liquid level situation concordant, can not flood thief hatch with ground level yet; adopt two guide rod modes can effectively prevent the rotation of ball float; make the ball float can be not stuck because of the winding of flexible pipe; can protect thief hatch not flooded by liquid level under the extreme environment situation again, sampling system can be overflowed gas to liquid level and be extracted reliably and detect.
