Technical Field

The utility model belongs to the technical field of gas sampling device structures, and particularly relates to a gas sampling device with a liquid inlet protection function.

Background

The main components of the conventional gas sampling device are a sampling analysis host and a sampling hose. The sampling analysis host comprises a display screen, various sampling data can be obtained rapidly, the length of a sampling hose is relatively large, the sampling hose can be flexibly bent, and the required gas sample can be fully collected even in various relatively narrow spaces.

On the other hand, for the sample analysis host, if a large amount of liquid enters the sample analysis host, the data accuracy of gas sampling detection can be obviously reduced, and even the host is directly damaged.

Therefore, a safety type gas sampling device with a liquid inlet protection function has appeared in the market, and the general principle of liquid inlet protection is generally as follows: the floating ball is arranged at the front end of the sampling hose, so that when more liquid is accumulated and is about to enter the sampling hose, the floating ball can seal the sampling hose, and then the accumulated liquid is intensively cleaned at one time, so that normal sampling air inlet operation can be performed.

The patent publication No. CN214121733U and publication No. 2021.09.03 discloses a high-precision double-gas-path sampler, which comprises a sampling shell, a first sampling port and a second sampling port, wherein a control panel and a display screen are arranged on the surface of the sampling shell, the first sampling port and the second sampling port respectively extend to the inside of the sampling shell through a first ventilating pipe and a second ventilating pipe, the end parts of the first ventilating pipe and the second ventilating pipe are respectively communicated with a first absorbing bottle and a second absorbing bottle, absorbing liquid is arranged in the first absorbing bottle, and an anti-suck-back piece is arranged between the first absorbing bottle and the first ventilating pipe and comprises an anti-suck-back pipe, a floating ball and a limiting part.

The sampler in the patent of the utility model has the following using method and advantages of the floating ball: when the diaphragm pump stops admitting air, in order to prevent that the absorption liquid of an inside absorption bottle from suck-backing to prevent in the straw, utilize the floater to block up spacing portion, avoid the absorption liquid to flow up, guarantee follow-up detection and measuring accuracy.

However, in the practical use process of the sampler, at least the following 2 defects exist, in other words, the technical problem to be solved by the utility model is that:

firstly, when the sampler starts to use and is filled with absorption liquid, as the floating ball has no transverse limiting structure, the floating ball can float everywhere on the continuously rising liquid level and shake, and the sampler needs to be manually pushed into the anti-falling straw, which is very troublesome.

Second, since the absorption bottle has only one bottle mouth position, when the absorption liquid needs to be poured out, the whole set of anti-falling straw device on the absorption bottle needs to be detached, which is also relatively troublesome and inefficient.

Therefore, in view of the above, there is an urgent need for a novel gas sampling apparatus that is difficult to allow the liquid that is accidentally sucked to enter the sample analysis host, and is convenient to collect, pour and clean.

Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-7, a gas sampling apparatus with liquid inlet protection function structurally comprises a sampling analysis host 11, a sampling hose 12, a floating ball 13, a buffer box unit 1 for receiving liquid a, an air inlet pipe 2 arranged on the buffer box unit 1, an air outlet pipe 3 arranged on the buffer box unit 1 and connected with the sampling hose 12 and used for clamping the floating ball 13, a middle plate unit 4 arranged on the buffer box unit 1 and used for transversely fixing the floating ball 13, a fixing rod 5 and a lifting drainage rod unit 6.

In this embodiment, liquid a may have 2 sources: 1. the sampling environment has liquid, for example, the sampling area is a water well or a sewer; 2. the sampling area contains a large amount of water vapor, which forms condensed water in the buffer tank unit 1, and for example, gas sampling operation is performed in a water washing workshop and a coating workshop.

In either case, a large amount of liquid needs to be prevented from entering the sampling hose 12, so that the floating ball 13 is always located under the air outlet pipe 3, so that when the liquid level rises and the risk of liquid entering the sampling hose 12 is relatively high, the floating ball 13 can block the air outlet pipe 3 in time, and at this time, the air inlet operation can be selectively closed until all accumulated liquid is intensively discharged from the lifting drainage rod unit 6.

In addition, the middle plate unit 4, the fixing rod 5 and the lifting drainage rod unit 6 ensure that the transverse movement of the floating ball 13 is completely limited according to the principle of 'three-point determination of one circle', namely, the floating ball is always right below the air outlet pipe 3, and the function to be plugged of the floating ball 13 is ensured to be permanently effective.

The lifting drainage rod unit 6 has a function of draining water outwards after being pulled out downwards, and even in a downwards pulled-out state, the floating ball 13 is still transversely clamped all the time, so that the functions of liquid inlet protection and plugging of the air outlet pipe 3 of the floating ball 13 are always in an effective state to be triggered.

Finally, the concentrated discharge position of the liquid a is not the position of the air inlet pipe 2 or the position of the air outlet pipe 3, so that the integral structure of the buffer box body unit 1, the air inlet pipe 2 and the air outlet pipe 3 can be ensured to be unnecessary to be disassembled in the whole normal use process, and the buffer box body unit is quite efficient.

The buffer box unit 1 comprises a rectangular box 101, an air inlet hole 102 and an air outlet hole 103 which are arranged on the top plate of the rectangular box 101, and a drain hole 104 which is arranged on the bottom plate of the rectangular box 101 and is inserted into the lifting drain rod unit 6.

In this embodiment, when the lifting drainage bar unit 6 opens the drainage hole 104, the general suction force at the air outlet pipe 3 is insufficient to suck the liquid a with a falling tendency, so that the liquid a is not required to stop even the air intake sampling operation during the concentrated drainage, which is very efficient.

The meaning of the "buffer" word means that: the liquid a is not sucked into the sampling hose 12 directly, but stays in the rectangular box 101, but the accumulation and stop amount cannot be too great, otherwise, the liquid level hits the air outlet pipe 3, and the liquid also enters the sampling analysis host 11, which is the purpose of setting the floating ball 13.

The lower end face of the air outlet pipe 3 is also provided with an elastic ring 7 for clamping the floating ball 13.

In this embodiment, the materials of the air inlet pipe 2, the air outlet pipe 3 and the floating ball 13 are all common hard plastics, so that good corrosion resistance and small weight are ensured, and the material of the elastic ring 7 is elastic rubber, so that the floating ball 13 can fully seal the air outlet pipe 3.

Otherwise, even if a large amount of liquid has accumulated in the rectangular box 101, the sample analysis host 11 can re-intake air, i.e. the intake pipe 2 continues to suck in liquid, and finally the sample analysis host 11 is damaged by water.

The middle plate unit 4 comprises a vertical plate 401 with two ends respectively arranged on the inner bottom surface and the inner top surface of the rectangular box body 101, positioned between the air inlet pipe 2 and the air outlet pipe 3 and used for transversely clamping the floating ball 13.

In this embodiment, the riser 401 has at least the following 3 roles: 1. the floating ball 13 is transversely clamped; 2. reinforcing the entire rectangular box 101; 3. the air flow is blocked between the air pipe 2 and the air outlet pipe 3, so that enough area is provided for condensation of the water vapor, and the water inflow in the sampling hose 12 is further reduced.

Therefore, the width of the vertical plate 401 needs to be relatively large, and a gap space with a width of 1-2cm is reserved between the two sides of the vertical plate and the inner side surface of the rectangular box 101 for passing gas.

The intermediate plate unit 4 further includes a first reinforcing block 402 provided on the riser 401 for connecting the intake pipe 2. The intermediate plate unit 4 further includes a second reinforcing block 403 provided on the riser 401 for connecting to the outlet pipe 3.

In this embodiment, the middle plate unit 4 may further strengthen the air inlet pipe 2 and the air outlet pipe 3 through the first strengthening block 402 and the second strengthening block 403, so that the stability of the device structure is better.

This is also an indirect advantage of the concentrated discharge of the liquid a at the drain hole 104. In other words, the air inlet pipe 2 is welded or adhered to the air inlet hole 102 and the air outlet pipe 3 is welded or adhered to the air outlet hole 103, and the detachability is not required to be considered.

The lifting drainage rod unit 6 comprises a lifting movable rod 601 which is inserted into the drainage hole 104 and is used for transversely clamping the floating ball 13, and a vertical drainage groove 602 which is arranged on the lifting movable rod 601.

In this embodiment, when the vertical drainage channel 602 is in drainage, the lifting movable rod 601 is still transversely engaged with the floating ball 13, so as to ensure that the floating ball 13 can only perform harmless self-rotation motion, i.e. is always located under the air outlet pipe 3.

The vertical length of the vertical drain channel 602 is greater than the thickness of the bottom plate of the rectangular box 101.

In this embodiment, the vertical drain channel 602 is longer than the thickness of the bottom plate of the rectangular box 101, so that the drain operation can be performed when the vertical drain channel 602 spans the drain hole 104. When the vertical drainage groove 602 is located above the drainage hole 104, the lifting movable rod 601 can properly plug the drainage hole 104, so that the buffer tank unit 1 can perform orderly and efficient centralized drainage operation without accidental water leakage in most of the time.

The lifting drainage rod unit 6 further comprises a limiting ring 603 which is arranged on the inner side surface of the rectangular box body 101 and sleeved with the lifting movable rod 601.

In this embodiment, the limiting ring 603 is configured to further improve the lateral stability of the lifting movable rod 601, so that the lifting movable rod 601 is stably engaged with the floating ball 13 no matter it is fixed or lifted and plugged.

The lifting drainage rod unit 6 further comprises an end block 604 which is arranged on the upper end surface of the lifting movable rod 601 and is used for clamping the limiting ring 603.

In this embodiment, the end block 604 is always located above the limiting ring 603, so as to ensure that the lifting movable rod 601 is not excessively pulled out.

In other words, when the end block 604 hits the limit ring 603, the vertical drain groove 602 spans the drain hole 104, and the space between the end block 604 and the top plate of the rectangular box 101 is insufficient to allow the floating ball 13 to pass through and escape.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
