Description

Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to a constant temperature pipe for heating an anchored lawn. Background Art

[0002] Lawns have many functions such as beautifying the environment, purifying the air, maintaining soil and water, reducing dust, eliminating noise, absorbing carbon dioxide and releasing oxygen, and providing outdoor activity places. Therefore, they are widely used in the construction of professional football fields. However, the growth of lawns has relatively high requirements for temperature. For the construction of anchored lawns in cold regions, a layer of heat-insulating material is usually covered on the surface of the lawn, which can ensure the survival of the lawn in winter. The method of using a surface-covered heat-insulating material has relatively high requirements for the heat-insulating material. If the heat-insulating material is heavy, the greater the pressure on the lawn, which is not conducive to the growth of the lawn. When the temperature is mild or hot, continuing to cover the heat-insulating material will cause the lawn to wither, and at this time, it is necessary to manually remove the covering of the heat-insulating material. Therefore, the method of using a covered heat-insulating material is both labor-intensive and has relatively high requirements for the heat-insulating material. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a constant temperature pipe for heating an anchored lawn, which is arranged in the lawn soil layer, and the external temperature information is received through the temperature sensor. If the temperature of the external soil layer is too low, the temperature sensor will transmit the soil layer temperature to the temperature control element, and the temperature control element controls the heating wire to heat; if the temperature of the external soil layer is too high, the temperature sensor will transmit the soil layer temperature to the temperature control element, and the temperature control element controls the heating wire to stop heating.

[0004] The technical solution for achieving the above purpose is a constant temperature pipe for heating an anchored lawn, which is used for the maintenance of the lawn. The constant temperature pipe includes:

[0005] A protection pipe, in which a heating wire is buried in the pipe wall;

[0006] A protective layer arranged in the protection pipe;

[0007] A temperature control element embedded in the protective layer, and the temperature control element is communicatively connected to the heating wire;

[0008] A temperature sensor arranged outside the protection pipe, and the temperature sensor is communicatively connected to the temperature control element;

[0009] A signal transmission pipe arranged in the protection pipe.

[0010] Further, the protective layer includes: a heat-insulating layer and an air separation pipe;

[0011] The air separation pipe is inserted into the protection pipe, and the temperature control element is embedded in the air separation pipe;

[0012] The heat insulation layer is disposed between the air separation tube and the protection tube.

[0013] Furthermore, the heat insulation layer is a polymer heat insulation material, and the air separation tube has a plurality of vacuum cavities therein.

[0014] Furthermore, a plurality of connecting brackets are provided between the protection tube and the air separation tube, and the heat insulation layer is embedded in the space formed by enclosing the connecting brackets, the air separation tube and the protection tube.

[0015] Furthermore, a plurality of support brackets are disposed in the air separation tube, one end of the support bracket is fixedly connected to the inner wall of the air separation tube, and the other end of the support bracket supports the signal transmission tube.

[0016] Furthermore, a power line and a signal transmission line are disposed in the signal transmission tube, and the power line is connected to the heating wire, the temperature control element and the temperature sensor;

[0017] The signal transmission line is connected to the temperature control element and the temperature sensor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, the external temperature information is received by the temperature sensor. If the temperature of the external soil layer is too low, the temperature sensor will transmit the soil layer temperature to the temperature control element, and the temperature control element controls the heating wire to heat; if the temperature of the external soil layer is too high, the temperature sensor will transmit the soil layer temperature to the temperature control element, and the temperature control element controls the heating wire to stop heating.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Refer to Figure 1 , a constant temperature pipe for heating an anchored lawn, which is used for lawn maintenance. The constant temperature pipe includes: a protection pipe 2, in which a heating wire 3 is embedded in the pipe wall of the protection pipe 2; a protective layer arranged in the protection pipe 2; a temperature control element 6 embedded in the protective layer, and the temperature control element 6 is communicatively connected to the heating wire 3; a temperature sensor 1 embedded outside the protection pipe 2, and the temperature sensor 1 is communicatively connected to the temperature control element 6; a signal transmission pipe 8 arranged in the protection pipe 2. Electrical signals are used to transmit information among the temperature sensor 1, the heating wire 3 and the temperature control element 6. The protective layer protects the temperature control element 6 from being damaged during the heating process, and the signal transmission pipe 8 supplies power to the temperature sensor 1, the temperature control element 6 and the heating wire 3.

[0026] In the present invention, a preferred embodiment is: the protection pipe 2 is buried in the soil layer under the lawn of a football field. Preferably, in the present invention, during the process of laying the protection pipe 2, the temperature sensor 1 needs to be located above the heating pipe. Since the football field lawn above is often used by people, the protection pipe 2 can protect the internal structure of the protection pipe 2 from being deformed or damaged due to external forces. The present invention receives external temperature information through the temperature sensor 1 and sends the temperature information to the temperature control element 6. The temperature control element 6 judges the temperature information of the soil layer received: whether the temperature of the soil layer is lower than the set temperature suitable for lawn growth. If the temperature of the external soil layer is too low, an electric signal for heating is generated through internal processing and judgment. The temperature control element 6 controls the heating wire 3 to heat through the heating electric signal. Under the action of heat conduction, the heating wire 3 dissipates its higher temperature to the external soil layer through the protection pipe 2 to raise the temperature of the soil layer of the lawn. If the temperature of the external soil layer is too high, that is, the temperature of the soil layer is greater than or equal to the set temperature suitable for lawn growth, the temperature control element 6 controls the heating wire 3 to stop heating through the stop heating electric signal. After one heating is completed, the real-time temperature information of the soil layer of the lawn will continue to be conducted according to the above process, and finally the temperature is maintained constant, achieving the effect of intelligent control of the soil layer of the lawn, so that the lawn can also be continuously insulated in winter or cold times. Preferably, in the present invention, a preferred embodiment is: an electric current transmission line is arranged between the signal transmission pipe 8 and the heating wire 3, and the temperature control element 6 is connected to the electric current transmission line. When the temperature of the surrounding soil layer is too low, the temperature control element 6 will make the electric current transmission line in an on state, and the heating wire 3 will heat. When the temperature of the surrounding soil layer is suitable or too high, the temperature control element 6 will disconnect the electric current transmission line, and the heating wire 3 will stop heating.

[0027] Preferably, the temperature sensor 1 and the temperature control element 6 use an electrical signal transmission line to transmit signals.

[0028] Preferably, during actual use, it often happens that due to the large area of the lawn, the soil layer far from the temperature sensor 1 cannot be well temperature-controlled. At this time, the temperature sensor 1 and the temperature control element 6 can be added. By arranging the temperature sensor 1 and the temperature control element 6 at intervals, temperature circulation can be achieved in each area within the lawn range.

[0029] Further, referring to Figure 2 and Figure 3 , the protective layer includes: a heat insulation layer 4 and an air separation tube 7; the air separation tube 7 is inserted into the protective tube 2, and the temperature control element 6 is embedded in the air separation tube 7; the heat insulation layer 4 is arranged between the air separation tube 7 and the protective tube 2. Preferably, in the present invention, the heat insulation layer 4 and the air separation tube 7 are provided. The heat insulation layer 4 absorbs heat, and the air separation tube 7 prevents heat from continuing to enter and affecting the temperature control element 6.

[0030] Further, the heat insulation layer 4 is a polymer heat insulation material, and the air separation tube 7 has a plurality of vacuum cavities. Preferably, the polymer heat insulation material can absorb most of the heat. Preferably, the polymer heat insulation material can use high foaming polypropylene or high foaming polypropylene. The vacuum cavities can block the entry of heat.

[0031] Further, a plurality of connecting brackets 5 are provided between the protective tube 2 and the air separation tube 7, and the heat insulation layer 4 is embedded in the space formed by enclosing the connecting brackets 5, the air separation tube 7, and the protective tube 2. The connecting brackets 5 support and fix the air separation tube 7. Further, a plurality of support brackets are arranged in the air separation tube 7. One end of the support bracket is fixedly connected to the inner wall of the air separation tube 7, and the other end of the support bracket supports the signal transmission tube 8.

[0032] Further, a power line and a signal transmission line are arranged in the signal transmission tube 8. The power line is connected to the heating wire 3, the temperature control element 6, and the temperature sensor 1;

[0033] The signal transmission line is connected to the temperature control element 6 and the temperature sensor 1.

[0034] In the present invention, a preferred implementation manner is: after the temperature sensor 1 receives the external temperature, the temperature control element 6 controls the power line connected to the heating wire 3 to be disconnected or closed through the signal transmission line.

[0035] The following describes the usage process of a constant-temperature pipe for warming an anchored lawn according to the present invention.

[0036] The present invention is buried in the soil layer under the lawn of a football field. Power is supplied to the heating wire 3, the temperature sensor 1, and the temperature control element 6 through the signal transmission pipe 8. Since the football field lawn above is often used by people, the protection pipe 2 can protect other structures inside the protection pipe 2 from deformation or damage caused by external forces. The present invention receives external temperature information through the temperature sensor 1 and sends the temperature information to the temperature control element 6. The temperature control element 6 judges the temperature information of the soil layer received: whether the temperature of the soil layer is lower than the set temperature suitable for lawn growth. If the temperature of the external soil layer is too low, an electric signal for heating up is generated after internal processing and judgment. The temperature control element 6 controls the heating wire 3 to heat through the heating-up electric signal. Under the action of heat conduction, the heating wire 3 dissipates its higher temperature to the external soil layer through the protection pipe 2 to raise the temperature of the soil layer of the lawn. If the temperature of the external soil layer is too high, that is, the temperature of the soil layer is greater than or equal to the set temperature suitable for lawn growth, the temperature control element 6 controls the heating wire 3 to stop heating through the stop heating-up electric signal. After one heating-up is completed, the real-time temperature information of the soil layer of the lawn will continue to be transmitted according to the above process, and finally the temperature is maintained constant, achieving the effect of intelligent control of the soil layer of the lawn, so that the lawn can also be continuously insulated in winter or cold times. After one heating-up is completed, the real-time temperature information of the soil layer of the lawn will continue to be transmitted according to the above process, and finally the temperature is maintained constant, achieving the effect of intelligent control of the soil layer of the lawn, so that the lawn can also be continuously insulated in winter or cold times.

[0037] The present invention has been described in detail with reference to the embodiments in the accompanying drawings. Those of ordinary skill in the art can make various variations to the present invention according to the above description. Therefore, some details in the embodiments should not constitute a limitation to the present invention, and the protection scope of the present invention will be defined by the scope of the appended claims.
