Embodiment 1
The present embodiment provides a kind of big water yield groundwater reservoir Level monitor, as shown in figure 1, being applied to big water yield
In groundwater reservoir.Including groundwater reservoir 101, top plate 102, dam body 103.And the present apparatus includes groove, drilling 201, Z
Shape sleeve pipe 202, pressure sensor 203, monitor terminal 204, cable 205.Wherein:
The groove, on the top plate 102 of groundwater reservoir, in the side wall of its end and the groundwater reservoir 101
Contacted at wire hole;The drilling 201, on the top plate 102, and the depth of the drilling 201 is more than the underground water
The maximum height 206 of the water level of storehouse 101;The Z-shaped sleeve pipe 202, it includes the first pipeline section, the second pipeline section and the 3rd pipeline section, described
First pipeline section is parallel with the 3rd pipeline section, first pipeline section stretch into the inside of the groundwater reservoir 101 and with the wire hole
In sealing contact, second pipeline section is set along the groove, and the 3rd pipeline section is stretched into inside the drilling 201;The pressure
Sensor 203, it is placed in inside groundwater reservoir 101, monitors the height of water level of the groundwater reservoir 101;Its power end and underground electricity
Source output terminal connects, and the output of its output end characterizes the electric signal of the height of water level;The monitor terminal 204, it inputs termination
The electric signal that the pressure sensor 203 exports is received, the height of water level is obtained according to the electric signal;The cable
205, it is placed in inside the Z-shaped sleeve pipe 202, connects the output end of the pressure sensor 203 and the input of monitor terminal 204
End, realize the data transfer of the pressure sensor 203 and the monitor terminal 204.
In such scheme, pressure sensor 203 has corrosion resistant waterproof case, by cable 205, with monitoring terminal
204 connections, as illustrated, carrying out hydraulic pressure and level measuring to groundwater reservoir 101.Pressure sensor 203 may be configured with 50Mb very
To the memory of more Large Copacity, the information for once characterizing level of ground water height is uploaded by GPRS module per the 3-10 seconds.Pressure passes
Sensor 203 is similar with general pressure sensor principle, and difference is, the pressure sensor 203 in this programme has bigger
Volume, the memory of larger capacity can be come with, and can almost accomplish to monitor and upload level of ground water elevation information in real time, such as
This can guarantee that groundwater reservoir water level monitoring is safe and reliable;The reason for this design can be accomplished, is as follows:Traditional pressure sensor exists
Field, power supply need the unstable power supply such as lithium battery or wind and solar energy, it is therefore desirable to and micro energy lose designs, and with monitoring field
Lower water level, changes and its slowly, several hours transmission primaries data or one day transmission primaries are all enough, and in this programme
Groundwater reservoir is under mine, power good, and groundwater reservoir SEA LEVEL VARIATION has the characteristics of fluctuation is big, usually the water of groundwater reservoir
Position height change less, but may need fast slowdown monitoring SEA LEVEL VARIATION situation when dangerous situation occurs, and reservoir has in itself
There is the very big underground space, the volume of pressure sensor do not limited, therefore the even more big memories of 50Mb can be accomplished,
And can be with high-frequency, almost real-time monitoring waterlevel data.
In addition, in such scheme, the main function of Z-shaped sleeve pipe 202 is used as protection pressure sensor 203 and cable 205,
The hydraulic pressure of groundwater reservoir 101 is exported to outside reservoir simultaneously and is connected with air, the hydraulic pressure and air pressure difference value of such sensor are just
The height of water level value of reservoir can be calculated;Z-shaped sleeve pipe 202 comes out between the top of dam body 103 and top plate 102, such design
The antiseepage demand around Z-shaped sleeve pipe 202 can be reduced, because being come out relative to back plate connections, greatly reduces Z-shaped sleeve pipe
Hydraulic pressure around 202, antiseepage is required to reduce, reduces job costs;Drilling 201 on top plate is the principle using linker,
The water of groundwater reservoir 101 is exported, because the water level of big water yield groundwater reservoir is often higher than the height of dam body 103, needed
A drilling 201 is played in top plate 102, ensure that reservoir water will not overflow and uncontrollable under normal circumstances.
The such scheme of the present embodiment, by introducing Z-shaped sleeve pipe, and set on top plate recessed with the cooperation of Z-shaped sleeve pipe
Groove, drilling, can be while the antiseep requirement of groundwater reservoir be met, using wired pressure sensor monitoring groundwater reservoir
The height of water level.Due to the sealing and protective effect of Z-shaped sleeve pipe, underground cables can transmit the signal of pressure sensor to prison
Control terminal.The power end of pressure sensor can be connected with down-hole power, can obtain stable electric energy, and groundwater reservoir pair
The volume of pressure sensor does not limit, therefore pressure sensor can be with autogamy memory, and can be with high-frequency, intimate reality
When monitoring waterlevel data.By the way of wired data transfer, signal is not influenced by the adverse circumstances, and durability is more
By force.
Embodiment 2
The big water yield groundwater reservoir Level monitor that the present embodiment provides, as shown in Figures 2 and 3, it is in embodiment 1
Scheme on the basis of, do following Optimal improvements:
The starting point of the groove is provided with fixture 207, and the second pipeline section middle part of the Z-shaped sleeve pipe 202 is by described
Fixture 207 is fixed on the groove starting point.Wherein, the fixed position of the second pipeline section, which disclosure satisfy that, makes the first pipeline section stretch into ground
Inside lower storage reservoir 101 so that the 3rd pipeline section is stretched into inside drilling 201.The fixture can be retainer ring, build dam body
Before 103, it is online that Z-shaped sleeve pipe 202 can be fixed on to the anchor of top plate by fixture 207, convenient construction and fixation.Further preferably
Ground, offer multiple hollow holes 208 on the tube wall of the first pipeline section of the Z-shaped sleeve pipe 202, it is ensured that pressure sensor 203 with
The abundant contact of water body.
In this programme, the pressure sensor 203 is transmitted to the monitor terminal 204 with predetermined period and characterizes water level height
The electric signal of degree, the predetermined period are the 3-10 seconds.In specific implementation, the pressure sensor 203 is according to the water monitored
The highly automated adjustment predetermined period in position, the height of water level is bigger, and the predetermined period is smaller, and works as the height of water level
During more than height upper limit value, the predetermined period is 3 seconds.Higher limit can be the distance at one meter of peak.Such energy
Enough it is further ensured that groundwater reservoir water level monitoring is safe and reliable.
In addition, in such scheme, monitor terminal 204 can use micro energy lose to design, and sensor is recorded by control board
Data, power supply use down-hole power, and inscribed transformer changes into direct current 12V power supplies, and it can carry standby lithium pond group
Power supply.Wireless communication module is may also be configured with inside it, is transmitted the height of water level to well by the wireless communication module
Lower center host 300.
