Description

Floating ball type gas sampling device with positioning function

Technical Field

The utility model belongs to the technical field of gas sampling auxiliary devices, and particularly relates to a floating ball type gas sampling device with a positioning function.

Background

The prior common gas sampler mainly comprises a host and a sampling tube, is quite convenient to operate when sampling is carried out in a region with enough space, can automatically display sampling data, and has simple and efficient whole sampling process.

However, in particular areas where space is relatively limited, such as in wells, sewer locations, etc., where gas sampling may occur, a number of operational difficulties may occur, including: 1. if the sampling tube is simply held, the sampling tube is difficult to extend into the area, and finally, the sampling data is not complete enough and the reality is low; 2. if the sampling tube is too deep, it is likely to be inserted directly into the liquid, which can cause large deviations in the sampling readings, even direct damage to the host of the sampler.

Therefore, for the auxiliary device of the gas sampler, the sampling tube can be ensured to deeply sample, and the water inlet of the sampling tube is avoided.

The patent publication No. CN201561884U and publication No. 2010.08.25 discloses a floating ball device for gas sampling, which comprises a cover plate, a guide rod, a floating ball fixing plate, a sampling port and a hose, wherein the cover plate is arranged at the highest point of the position of the gas sampling point, one end of the hose is communicated with the sampling port, the other end of the hose extends out of the upper part of the cover plate, the sampling port is fixed below the cover plate through a support rod, the other end of the support rod is fixed on the floating ball fixing plate with small holes, the guide rod is fixed on the cover plate through the small holes, and the floating ball is arranged on the floating ball fixing plate.

The gas sampling floating ball device in the patent of the utility model has the advantages that: the sampling port is always kept above the liquid level at a specified distance, the sampling port cannot be submerged, and the sampling system can reliably extract and detect liquid level overflow gas.

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

firstly, the height difference between the sampling port and the liquid level is fixed and not adjustable, and when the liquid level is fixed and the sampling operation is required to be performed on a gas sample at a position with a small height above the liquid level, the sampling device cannot take the gas sample;

second, the device lacks a safe and convenient positioning function, for example, when the vertical multipoint sampling in the water well is performed, the accurate ground-leaving height of the sampling point cannot be determined, so that the operation of the whole gas sampling operation is relatively rough.

Therefore, in view of the foregoing, there is an urgent need for a novel gas sampling apparatus having a positioning function and a floating ball function, for use in a relatively narrow limited space.

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. 1-8, a floating ball type gas sampling device with a positioning function structurally comprises a floating ball 11, a positioner 12, a sampler 13, an open hole underframe unit 1 provided with the floating ball 11, an open hole pressing plate unit 2 arranged on the open hole underframe unit 1 and used for clamping and fixing the floating ball 11, a lifting plate unit 3 arranged on the open hole underframe unit 1 and used for installing the positioner 12 and the sampler 13, and a rope top plate unit 4 arranged on the open hole underframe unit 1 and used for covering and protecting the positioner 12.

In this embodiment, the floating ball 11 is an existing fully-sealed hollow plastic ball, the locator 12 is an existing battery-type stand-alone GPS locator, and the sampler 13 has 2 different methods of use, namely: 1. the sampler main body is placed on the ground for operation, the sampling tube is longer and is arranged on the lifting plate unit 3; 2. the sampler main body is also arranged on the device and enters the sampling space together, and the sampler main body is provided with an automatic sampling recording program, so that the sampling operation at a plurality of positions in the space can be automatically carried out, recorded and saved.

Wherein the device comprises 3-4 floating balls 11, and is entirely clamped between the perforated underframe unit 1 and the perforated pressing plate unit 2. In other words, the diameters of the holes on the two units are smaller than the diameter of the floating ball 11, so that the floating ball 11 is finally stably installed, and at least the hole pressing plate unit 2 cannot enter a position below the liquid surface, and the floating ball 11 stably floats.

Furthermore, the lifter plate unit 3 has at least the following 3 roles: 1. stably mounting the positioner 12 and the sampling tube; 2. so that the height of the positioner 12 and the sampling tube remain consistent, i.e. the positioning depth is the sampling depth; 3. the height difference between the sampling tube and the liquid level can be further fine-tuned on the premise of ensuring safety, so that the gas sampling operation is more comprehensive.

Finally, the corded roof unit 4 has at least the following 2 roles: 1. the device is provided with a suspension function, so that the device can be lowered and lifted, and the device can be used for sufficiently sampling in multiple points in a relatively narrow space; 2. so that the relatively expensive positioner 12 is not easily broken by dropped objects and is not easily wetted by dropped water.

The perforated chassis unit 1 includes a base plate 101, a supporting hole 102 provided on the base plate 101 for engaging the floating ball 11, and a stud 103 provided on the upper surface of the base plate 101 and passing through the perforated platen unit 2 and the lifter plate unit 3.

In this embodiment, the shape of the bottom plate 101 is triangular or square, that is, the shape of the supporting hole 102 is circular corresponding to 3 or 4 floating balls 11.

The perforated chassis unit 1 further includes a pad 104 disposed on the lower surface of the base plate 101 for lifting the floating ball 11 off the ground.

In this embodiment, the pad 104 has at least the following 2 functions: 1. when the device is placed on the ground for rest, the cushion block 104 can lift the floating ball 11 off the ground, so that the floating ball 11 is prevented from being worn out greatly and for a long time, and the air tightness of the floating ball 11 is the key point of floating the device; 2. the spacer 104 can make room under the base plate 101 when the device is assembled, so that the floating ball 11 is directly pressed against the supporting hole 102 instead of being pressed against the ground, and the base plate 101 and the floating ball 11 are still relatively separated and movable in the latter way, which further affects the quick and stable installation of the perforated platen unit 2.

The perforated chassis unit 1 further includes a positioning column 105 disposed on the upper surface of the base plate 101 and used for plugging the perforated platen unit 2 and the lifter plate unit 3.

In this embodiment, since the stud 103 is cylindrical, the perforated platen unit 2 and the lifter plate unit 3 may be rotationally displaced during installation and use, which may result in the following accidents and disadvantages: 1. the perforated pressing plate unit 2 cannot be aligned with the floating ball 11 quickly, or is rotated and staggered after being aligned; 2. after the lifting plate unit 3 rotates, the positioner 12 is not directly under the roped top plate unit 4, so that the covering and protecting functions of the positioner 12 by the roped top plate unit 4 are greatly reduced.

So in summary, this is the effect of introducing the positioning post 105.

The perforated platen unit 2 includes a plate body 201, a mounting hole 202 provided in the plate body 201 and penetrating the stud 103, a locking hole 203 provided in the plate body 201 and used for fixing the float 11, and a fastening nut 204 provided on the upper surface of the plate body 201 and connected to the stud 103.

In this embodiment, the shape and size of the plate 201 are aligned with the bottom plate 101, the positions, the number and the sizes of the engaging holes 203 are aligned with the supporting holes 102, and the fastening nuts 204 are rotated toward the direction of the perforated chassis unit 1, so that all the floating balls 11 can be stably mounted.

The perforated platen unit 2 further includes a first positioning hole 205 disposed on the plate 201 and inserted into the positioning post 105.

In this embodiment, the first positioning hole 205 is inserted into the positioning post 105, then the plate 201 slides to engage with the floating ball 11, and finally the fastening nut 204 is screwed.

The lifter plate unit 3 includes a plate 301, an opening 302 provided on the plate 301 and passing through the stud 103, a locator opening 303 and a sampling tube opening 304 provided on the plate 301, and adjustment nuts 305 provided on upper and lower surfaces of the plate 301 and connected to the stud 103, respectively.

In this embodiment, the flat plate 301 is rectangular in shape, and the locator opening 303 and the sampling tube opening 304 are located on two sides of the opening 302, respectively, so that the weight of the two sides of the lifting plate unit 3 is balanced as much as possible.

In addition, the number of adjustment nuts 305 is 2 and are simultaneously adjusted upward or rotated downward, ensuring that the height of the positioner 12 and sampling tube can be further fine-tuned.

The lifter plate unit 3 further includes a second positioning hole 306 disposed on the flat plate 301 and inserted into the positioning post 105.

In this embodiment, when the device is in use, the sampler main body is not located on the lifting plate unit 3, so that the corded top plate unit 4 only needs to cover and protect the positioner 12, so that the size of the corded top plate unit 4 is relatively small, and the weight of the device can be further reduced and optimized.

Therefore, the lifting plate unit 3 cannot be rotated any more at this time, and the retainer 12 is prevented from moving out of the position directly below the corded roof unit 4, which is why the flat plate 301 is also inserted into the positioning column 105.

The corded roof unit 4 includes a top plate body 401 provided on an end surface of the stud 103 and covering the locator aperture 303, and a suspension cord 402 provided on the top plate body 401.

In this embodiment, the top plate 401, the stud 103, and the bottom plate 101 are relatively fixed, that is, they may be integrally formed, thereby forming an overall skeleton of the device.

The corded roof unit 4 further includes a rectangular frame 403 provided on the upper surface of the top plate 401 and used for mounting the sampler 13 when the apparatus is in use and idle.

In this embodiment, when the device is used, since the sampler main body may also be installed along with the sampler main body and enter the sampling space together, the rectangular frame 403 is provided, so that the sampler main body may be stably clamped in the rectangular frame 403 and is not easy to fall when the device is lowered and lifted.

The rectangular frame 403 is open-sided, i.e. comprises an inverted U-shaped plate and an end plate, so that the sampler main body is guaranteed to fully enter and be clamped between the rectangular frame 403 and the top plate 401. But now one end of the sample tube remains on the sample tube aperture 304.

In addition, when the device is idle and waiting to be used, the sampling tube is taken down from the sampling tube opening 304 and is stored in the rectangular frame 403 together with the sampler main body, so that the device and the sampler can be always matched for use, and the sampler is not easy to fall and lose.

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.
