Technical field
The utility model relates to a kind of soil moisture monitoring device.
Background technology
Pressure energy-conservation along with country and that reduce discharging strengthens, and soil source heat pump system has obtained increasing application as a kind of power-saving technology.Its advantage is mainly reflected in: (1) is easy to control and pollutes few owing to the main consumed power of heat pump; (2) when heat pump cooling and heat supply, the main source of energy is an energy stored in the underground, is regenerative resource, can use continuously; (3) adopt electricity refrigeration form, the coal-fired central heating form of employing of cooling tower to compare with other, soil source heat pump system has higher efficient.According to related data, the efficient of soil source heat pump system improves can reach 20%-30%.
In the soil source heat pump system, the temperature variation of underground is most important for the normal operation of soil source heat pump system.Normally in service, if when the thermal load in winter and summer and refrigeration duty are serious uneven, will cause the soil source heat pump system operational efficiency to reduce, even heat pump (cooling and heating) system is scrapped.Owing to most soil source heat pump systems relevant underground device for detecting temperature is not installed at present, thereby the quantitative data of underground temperature variation can't be provided.This mainly is because there are certain difficulty in the measurement of underground deep layer soil and memory technology, and because soil source heat pump system ground pipe laying floor area is generally more, field wiring connects and also has big difficulty.
The utility model content
The technical matters that the utility model will solve provides a kind of simple in structure, more convenient monitoring device of the soil moisture accurately of measurement.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of soil moisture monitoring device; It comprises the polyethylene pipe that vertically is embedded in the surface drilling; Be uniformly distributed in around the polyethylene pipe from top to bottom and the temperature sensor that is fixed together with it, the digital cable for measuring temperature that is connected with the output terminal of all temperature sensors, the data acquisition unit that joins with digital cable for measuring temperature and with two-way calculating that is connected of said data acquisition unit and display unit.
The said temperature sensor is provided with 2～20.
The model of above-mentioned data acquisition unit is OM-CP-OCTTEMP.
Adopt the beneficial effect that technique scheme produced to be:
(1) the utility model mainly is through being embedded in after temperature sensor in the underground obtains temperature data; Handle and storage through data acquisition unit; Finally in calculating and display unit, realize data presentation and processing, it has solved continuous coverage and the supervision problem of soil source heat pump in normal deep soil temperature in service, and not only one-piece construction is fairly simple; And convenient measurement can provide accurate data for soil source heat pump normally moves and eliminate uneven thermal load.
(2) employing the utility model has solved the storage problem of the thermometric data of soil source heat pump system deep subsoil, for soil source heat pump provides scientific basis to surrounding soil Influence of Temperature and sustainability thereof.

Said temperature sensor 2 can be provided with a plurality of, and as 2～20, every separated 10m can be provided with one, evenly distributes along polyethylene pipe 3 vertical directions.
Mode through connection between data acquisition unit 5 and calculating and the display unit 6 is connected, and the agreement communications protocol.The data acquisition parameters of data acquisition unit 5, the parameters such as the time interval like beginning acquisition time, end acquisition time, data acquisition can be provided with through the Control Software that is loaded in the data acquisition unit in calculating and the display unit 6.After completion was set, the data acquisition of data acquisition unit 5 can require independent the completion according to being provided with.When data acquisition unit 5 and calculating and display unit 6 are in when being connected, data that can the Real Time Observation collection in worksite; When data acquisition unit 5 temporarily is not connected with calculating and display unit 6, the single 5 yuan of functions that still can accomplish data acquisition and storage of said data acquisition.
Calculating of the utility model and display unit adopt data processing software that image data is exported as formatted form and carry out the data preservation, like text or Excel file according to the collection in worksite data of obtaining.
The work progress of the utility model is following:
1) in the soil of selected address, bores the dark surface drilling 4 of about 150mm;
3) with well cementings such as concrete with surface drilling 4 backfills;
Digital cable for measuring temperature 1 is connected to data acquisition unit 5, and data acquisition unit 5 is connected 6 with calculating and display unit.
