Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Some nouns of locality are defined in the present invention, and in the case where not being specified to the contrary, the used noun of locality is such as
" top, middle part, lower part, top " refers to what mounting post 1 provided by the invention defined under normal usage, and with attached drawing 1
Shown in " top, middle part, lower part, top " direction it is consistent.These nouns of locality are to use in order to facilitate understanding, because without
Constitute limiting the scope of the invention.
As shown in Figure 1, it is respectively a kind of structural schematic diagram of inspection shaft liquid level emasuring device provided by the invention.The inspection shaft
Liquid level emasuring device includes mounting post 1 and at least one level gauging mechanism 2, and mounting post 1 is fixedly arranged on the inner wall of inspection shaft 10, peace
It fills and is equipped with cavity 11 in column 1, and the lower sides of mounting post 1 are equipped with multiple first through hole 12, level gauging mechanism 2 is set to cavity
In 11.Mounting post 1 is fixed on inspection shaft by using being placed in level gauging mechanism 2 in the cavity 11 of mounting post 1 by the present invention
On 10 inner wall, so that level gauging mechanism 2 will not cause cannot be to inspection shaft because water flow is excessive there are rubbish or flow rate of water flow
10 liquid levels effectively measure, to solve the problems, such as that inspection shaft liquid level, which exists in the prior art, effectively to be measured.
Specifically, mounting post 1 be set to inspection shaft 10 in far from water (flow) direction inner wall on, due to water flow flowing when, water flow with
The contact of mounting post 1 can generate thrust to mounting post 1, excellent to guarantee that mounting post 1 can be firmly fixed on the inner wall of inspection shaft 10
Choosing is set on the inner wall in inspection shaft 10 far from water (flow) direction using by mounting post 1.
Specifically, the upstream face of lower sides is not provided with first through hole 12, and back side is equipped with multiple first through hole 12, water flow
Present in dirt can be moved along water flow flow direction, to guarantee that these dirts enter the cavity 11 of mounting post 1 as few as possible
In, in the upstream face of the lower sides of mounting post 1, it is preferably not provided with first through hole 12 (or hole), and by being set in its back side
Setting hole (i.e. first through hole 12) may make liquid to enter in cavity 11, to complete the measurement to 10 liquid level of inspection shaft.
Specifically, mounting post 1 further includes upper portion side wall and middle part of sliding channel, and upper portion side wall and middle part of sliding channel are equipped with multiple
Two through-holes 13.If it is larger containing amount of contaminants in 10 liquid of inspection shaft, or even the first through hole 12 of 1 lower part of mounting post is caused to block up
Plug, then the work by liquid drain into cavity 11 can be played by the second through-hole 13 being arranged in the middle and upper part of mounting post 1
With to complete subsequent level gauging work.
Specifically, the diameter of first through hole 12 is preferably 1cm~2cm, and the diameter of the second through-hole 13 is preferably 2cm~4cm.
The diameter setting of first through hole 12 is smaller, dirt can be prevented directly through first through hole 12, and enter cavity 11
In, avoid the measurement result to level gauging mechanism 2 from interfering；It is more top since the amount of the usual lower part dirt of liquid is more
The amount of dirt is smaller, therefore the setting of the diameter of the second through-hole 13 is somewhat larger, may make liquid that can quickly enter cavity 11
In, so that it is guaranteed that inspection shaft liquid level emasuring device is more rapidly completed to install and be measured.
Specifically, level gauging mechanism 2 is pressure sensor, and wherein at least one pressure sensor is set under cavity 11
Portion, and it is corresponding with first through hole 12.In present embodiment, it is preferred to use pressure sensor surveys 10 liquid level of inspection shaft
Amount, it is to be understood that liquid level can also be measured using other way.
Specifically, pressure sensor is equipped at least two (pressure sensor is only shown in figure), each pressure sensing
Device is series in cavity 11 up and down by cable.Such as the pressure sensor closer to liquid bottom, the numerical value of measurement is bigger,
Closer to maximum range.If the pressure sensor of lowest part has reached the maximum range, it can be passed by the pressure of upper part
Sensor continues to measure liquid level, is finally overlapped the result that multiple pressure sensors measure to get liquid level is arrived.
Specifically, which further includes data gather computer structure 3, set on the top of mounting post 1, and with
Pressure sensor is electrically connected, the pressure measurement information that data gather computer structure 3 is sent for acquiring pressure sensor, in practical application
Data gather computer structure 3 forms a series of conversion formula for above-mentioned in the way of pressure measurement liquid level, i.e., actually
The pressure sensor of mounting post 1 and Qi Nei is deep into liquid bottom in, the liquid level of inspection shaft 10 can be directly obtained.
The present invention also provides a kind of inspection shaft level measuring methods, use above-mentioned inspection shaft liquid level emasuring device, specific to wrap
Include following steps:
Level gauging mechanism 2 is mounted in the cavity 11 of mounting post 1, and mounting post 1 is fixed on to the inner wall of inspection shaft 10
On；
Enter liquid in cavity 11 by first through hole 12, for carrying out level gauging.
The inspection shaft level measuring method, and will peace by using being placed in level gauging mechanism 2 in the cavity 11 of mounting post 1
Dress column 1 is fixed on the inner wall of inspection shaft 10, so that level gauging mechanism 2 will not be due to water flow be excessive there are rubbish or flow rate of water flow
Cause effectively measure 10 liquid level of inspection shaft, to solve asking of existing in the prior art that inspection shaft liquid level can not measure effectively
Topic.
The inspection shaft level measuring method further include: first through hole 12 is arranged in the back side of mounting post 1.Exist in water flow
Dirt can be moved along water flow flow direction, to guarantee that these dirts enter as few as possible in the cavity 11 of mounting post 1, pacifying
Fill column 1 lower sides upstream face, be preferably not provided in first through hole 12 (or hole), and by its back side providing holes (i.e.
First through hole 12) it may make liquid to enter in cavity 11, to complete the measurement to 10 liquid level of inspection shaft.
