Description
Affiliated technical field
The present invention relates to a kind of water-level and water-temperature measuring instrument, especially be applicable to the portable water-level and water-temperature measuring instrument of earthquake prediction and water resources management department measurement inspection well water level and water temperature.
Background technology
Geologic hazards such as earthquake are huge to the disaster that people bring; Though also there is not reliable method for forecasting earthquake at present; But observe the slight change of phreatic water level and water temperature; Still can obtain some useful data relevant, therefore should a kind of usefulness, portable water-level and water-temperature measuring instrument of being simple and easy to be provided for the earthquake prediction personnel with earthquake.
Chinese patent instructions 87214793.2 discloses a kind of underground water table water temperature testing recorder.This water-level and water-temperature testing recorder is sealed in the cylindrical housing; Housing contains pressure transducer and temperature sensor; Be fixed in undersurface certain fixed position in the inspection well with wire rope with registering instrument is outstanding during use, this registering instrument just can get off the water-level and water-temperature data recording, from well, puts on registering instrument when needing and reads its data recorded; Obviously this is a kind of fixed water-level and water-temperature registering instrument; Be not easy to carry and observation at any time, its adopts pressure sensor is measured water level in addition, and the data that this method obtains precision concerning earthquake department is on the low side.
Chinese patent instructions 200420008865.4 discloses another kind of missile silo water-level and water-temperature automatic acquisition device.It comprises a pressure transducer that is placed on the sounding rod in the missile silo and is arranged on the sounding rod bottom and temperature sensor and be arranged on top, ground and with the data acquisition unit that links to each other with temperature sensor in pressure transducer.This water-level and water-temperature automatic acquisition device is different with the structure of aforesaid water-level and water-temperature testing recorder, but this also is a kind of fixed water-level and water-temperature registering instrument, equally is not easy to carry and the data precision problem of lower.
Summary of the invention
The technical matters that the present invention will solve provides the high and portable water-level and water-temperature measuring instrument simple in structure of a kind of data precision.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: the bottom at the lower house of water-level and water-temperature gage probe has water inlet, is provided with float in the lower house; When probe got in the water, float upwards floated, for guaranteeing that float floats rapidly reliably; The top of cavity has vent port at the float place, discharges the air that hinders the float come-up, and the top of described float is provided with permanent magnet; Bottom at upper shell is provided with temperature sensor; This sensor stretches out from upper shell and gets into lower house and do not contact with the inwall of lower house, is provided with tongue tube in the position parallel with this temperature sensor, and this tongue tube is connected with described temperature sensor and with twin-core RVV place in circuit; When the float come-up is near described tongue tube in the probe entering water; The magnetic field of described permanent magnet makes the closing of contact of tongue tube, and the sensor passage in the circuit becomes the temperature sensor access state about 10 kilo-ohms by original open-circuit condition, and the microcomputer controller in the circuit assembly can be found this variation according to program at this moment; Drive hummer and luminotron and send acousto-optic hint; Read the meter ruler number of division on the twin-core jacketed cable line this moment, can obtain the water level surveyed, and the minimum resolution of the meter ruler scale on the described twin-core jacketed cable line is a millimeter; The sectional area of wire of this RVV is not less than 0.75 square millimeter, and microcomputer controller begins to become numeral displays temperature on LCDs to the conversion of signals of temperature sensor according to program in the circuit simultaneously.
As further improvement of the present invention; Described lower house and upper shell adopt the stainless steel manufacturing, and last lower house is with being threaded, when it is characterized in that preventing to get rusty; Also make probe have suitable weight; Need not join in addition for this probe and keep vertical when tup can make cable go into well, the transition of described upper shell shoulder chamfering is not stuck when guaranteeing from well, to propose probe.
As another improvement of the present invention; Inner at described upper shell with waterproof material filling fixed temperature sensor and tongue tube and twin-core sheathed conductor; Have the heat-shrink tube seal groove on the top of upper shell, the periphery of sealing groove is with heat-shrink tube protection twin-core RVV.
The invention has the beneficial effects as follows that this water-level and water-temperature measuring instrument is easy to carry, the level measuring ratio of precision is higher can to reach the millimeter level; That pops one's head in is simple in structure, is easy to clean and safeguard, probe moves up and down in well flexibly during use; Be difficult for being stuck, use liquid crystal display displays temperature power consumption low.
