Background technique

Agricultural greenhouse greenhouse is after modern science and technology productivity is promoted, and mankind's nature remodeling obtains one kind of more foods Mode.The main reason for agricultural greenhouse greenhouse is promoted in recent years is: daytime increases room temperature using the energy of sunlight, Night utilizes a series of Insulations, reduces the loss of heat as far as possible.So, environment of the crops in suitable temperature Under, it can grow faster, to achieve the purpose that high yield.

The natural temperature of summer is relatively high, and crops can grow naturally in a natural environment.The temperature in winter in spring and autumn omits It is low, the purpose of increasing both production and income can be obtained with agricultural greenhouse greenhouse.But in winter in one or two months of most severe cold, night temperature Heat losses are more in the greenhouse of room, and temperature is decreased obviously, and bring adverse effect to the normal growth of crops.

As a result, it is thought that the method that is much heated to greenhouse, for example, conventional method has:

1, in greenhouse, coal heating heating is burnt.Its major advantage is: simple and easy, cost is not high.The disadvantage is that: have Pollution, does not meet the main trend of the national following environmental protection, and manpower consumption is also big.

2, warm wind is manufactured with electric heater or warm-air drier, major advantage is: it is convenient, quickly, and simply, environmental protection.The disadvantage is that: energy The utilization efficiency of amount is not high, and the cost of operation is relatively high.

3, push up inner embedment heater in soil, such as: hot water pipeline or heating wire or Electric radiant Heating Film etc..This method, It is possible in theory, but in practical applications, many troubles are encountered, because many crops are that rotation some months is primary, soil is pushed up It needs to turn over, this brings a challenge to the heater in soil: if it is shallow embedding heater, then being easy to be touched in turning over Wound is broken, and is caused damages.If it is buried heater, then the earth excavation at initial stage is at high cost, it has not been convenient to, effect is utilized to thermal energy Rate is also low.

4, some other heating method that may be inquired into: for example: generating heat using combustion of natural gas or oil firing generates Heat perhaps generates heat using solar water heater or utilizes earth source heat pump, water resource heat pump generation heat, these methods, It is possible in theory, also have application in some areas, but be widely popularized value it is limited, main cause is: greenhouse is generally off-site from The offer in city, this energy is inconvenient, alternatively, also not having practical market price value since up-front investment cost is too big.

Further, electric heating material described in the utility model preferentially selects carbon fiber heating line.The utility model is preferential It using the long service life of carbon fiber heating line, can once invest, coming few decades Reusability.And metal class line with heating function is deposited A possibility that service life is short and disadvantage, it is unfavorable for long-term investment use.

The stereoplasm tube is galvanized iron conduit.It is preferential to select galvanized iron conduit, because its is at low cost, good heat conductivity, durability It is good, there are comparable intensity, rigidity, reusable, survivability might as well.

It is respectively set for operating easily, in the end of the end of each group electric heating material and independent power source line mutually matched Connector assembly.Before digging again, the corresponding connector assembly of separation need only be passed through, so that it may realize cutting for electric heating material and power supply It is disconnected.It, also only must be by the way that connector assembly be connected to each other again after digging into ridge again, so that it may realize electric heating material and power supply It connects.

Detailed description of the invention

Fig. 1 is the schematic diagram that the utility model arranges electric heating material between field.

Specific embodiment

As shown in Figure 1, arranging a plurality of field 1 being parallel to each other in greenhouse, shallow soil is buried respectively between adjacent field 1 If one with the almost parallel stereoplasm tube (preferably galvanized iron conduit) 2 of field 1, it is exhausted that one group of peripheral hardware is respectively placed in each stereoplasm tube 2 Two ends of the carbon fiber heating line 3 of edge layer, carbon fiber heating line 3 stretch out in two ends of stereoplasm tube 2 respectively.

Power supply main line is set in greenhouse, and the in parallel and multicomponent power supply line on power supply main line, the quantity of independent power source line is not Less than the quantity of the stereoplasm tube 2 in greenhouse.

It is respectively set in the end of each carbon fiber heating line 3 and the end of each component power supply line and mutually matched patches group Part.

Using example:

1, in the hanging power supply main line in the top of greenhouse, and ensure not influence personnel's normal walking, also to carry out safety Insulation.Such as: in the southern side overhead of greenhouse, the power supply line of 10 square millimeters of suspension, as zero curve.In the north of greenhouse Side, three 10 square millimeters of power supply line of suspension, as firewire, and ensure to be powered in the future operation when, threephase load balance.

2, from hanging power supply main line, parallel connection simultaneously connects sagging multicomponent power supply line, and carries out insulating protection, and ensure to connect It connects reliable.

3, carbon fiber heating line is penetrated in galvanized iron conduit, and by the power supply lead wire of carbon fiber heating line with suitable length It is exposed at outside galvanized iron conduit, road wiring is constructed after convenience.Above-mentioned carbon fiber heating line can be using single guide structure, can also be using double Therefore guide structure can distinguish extracting power supply cord from the both ends of galvanized iron conduit, can also be from one end extracting power supply cord.But regardless of How to draw, it is proposed that at the both ends of galvanized iron conduit, sealing waterproof measure is taken, such as: using glass cement filling sealing.In each group Plug, the convenient installation of rapid construction in the future are pre-installed on independent power source line lead.Above-mentioned galvanized iron conduit, if joint length is inadequate, It can then be concatenated using more, be connect with screw thread with swivel nut at concatenation.

4, the above-mentioned galvanized iron conduit for installing carbon fiber heating line is placed on soil, and ensures root from crops less Far, and on pipeline a thin layer of soil is covered, to be conducive to heat transfer in pipeline to entire soil.If do not covered Thin soil also can be used, but heat transfer efficiency is impacted.

5, on the basis of above-mentioned completion, by the power supply lead wire of each carbon fiber heating line, with sagging each independent power source line Lead connects one by one respectively, and it is reliable to ensure to insulate, and route is errorless.

6, so far, above-mentioned general supply line, summarizes into distribution box, is controlled by battery main switch, the power transmission in weather cold Heating stops heating in temperature height and then power-off, has been provided with basic utility function.Certainly, from a safety viewpoint It sees, in distribution box, it should have short-circuit protection and earth leakage protective, these belong to the basic common sense of electrician.
