Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a heating device for anchoring lawns in cold regions. Background Art

[0002] Lawns have many uses, including beautifying the environment, purifying the air, conserving water and soil, reducing dust, eliminating noise, absorbing carbon dioxide and releasing oxygen, and providing a venue for outdoor activities. Therefore, they are widely used in the construction of professional football fields. However, lawn growth requires relatively high temperatures. For anchored lawn construction in cold regions, a layer of insulation material is usually applied to the lawn surface to ensure its survival in winter. This method of using surface insulation material has high requirements for the insulation material. The heavier the insulation material, the greater the pressure on the lawn, which is not conducive to its growth. In mild or hot temperatures, continued insulation covering will cause the lawn to wither, and manual removal of the insulation material is required. Therefore, using insulation covering is both labor-intensive and places high demands on the insulation material. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a heating device for anchoring lawns in cold regions. The device is arranged in the lawn soil layer and receives external temperature information through the temperature sensor. If the temperature of the external soil layer is too low, the temperature sensor will send a temperature signal to the heating pipe, and the heating pipe will judge whether the received temperature signal is lower than the temperature suitable for lawn growth. If so, the heating pipe will release heat; if the temperature of the external soil layer is too high, the temperature sensor will send a temperature signal to the heating pipe, and the heating pipe will judge whether the received temperature signal is greater than or equal to the temperature suitable for lawn growth.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figure 1 A heating device for anchoring lawns in cold regions is used for lawn maintenance. The heating device includes: a heating tube 3 arranged in the soil below the lawn; a plurality of temperature sensors 2 arranged on the outside of the heating tube 3, and the detection end of the temperature sensor 2 is located at the root of the lawn for real-time detection; a power supply 1 connected to the heating tube 3 is arranged on one side of the lawn.

[0036] In the present invention, a preferred embodiment is as follows: the power supply 1 provides power to the temperature sensor 2 and the heating tube 3. Preferably, in summer or when the weather is favorable, the power supply 1 can be turned off to save energy. During cold weather, the power supply 1 is turned on, and the temperature sensor 2 receives the real-time temperature of the soil at the roots of the lawn and transmits it to the heating tube 3, which then heats the lawn. When the soil temperature is too high, the power supply is turned off, and the heating tube stops heating. This cycle repeats, thereby achieving dynamic control of the growth temperature of the anchored lawn.

[0037] For further information, see Figure 3 and Figure 4 The heating tube 3 includes: a protective tube 13, a heating wire 14 is embedded in the tube wall of the protective tube 13, and the temperature sensor is communicatively connected to the heating wire 14; a protective layer arranged in the protective tube 13; a temperature control element 20 embedded in the protective layer, and the temperature control element 20 is communicatively connected to the heating wire 14; and a signal transmission tube 18 arranged in the protective tube 13.

[0038] In the present invention, a preferred embodiment is: since the lawn above is often used by people, the protective tube 13 can protect the internal structure of the protective tube 13 to prevent it from being deformed or damaged 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 20. The temperature control element 20 judges the received temperature information of the soil layer: 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, a heating electrical signal is generated after internal processing and judgment. The temperature control element 20 controls the temperature of the soil layer through the heating electrical signal. The heating wire 14 is heated, and under the action of heat conduction, the heating wire 14 dissipates its own higher temperature to the external soil layer through the protective tube 13, so as to heat up 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 20 controls the heating wire 14 to stop heating by means of a stop heating electrical signal; after completing one heating, the real-time temperature information of the soil layer of the lawn will continue to be transmitted according to the above process, and finally maintain the constant temperature, so as to achieve the effect of intelligent control of the lawn soil layer, so that the lawn can be continuously kept warm in winter or cold times. Preferably, in the present invention, a preferred embodiment is: a current transmission line is provided between the signal transmission tube 18 and the heating wire 14, and the temperature control element 20 is connected to the current transmission line. When the temperature of the surrounding soil layer is too low, the temperature control element 20 will turn on the current transmission line and the heating wire 14 will be heated. When the temperature of the surrounding soil layer is suitable or too high, the temperature control element 20 will disconnect the current transmission line and the heating wire 14 will stop heating.

[0039] For further information, see Figure 5 The protective layer includes: a heat-insulating layer 15 and an airtight tube 17; the airtight tube 17 is inserted into the protective tube 13, and the temperature control element 20 is embedded in the airtight tube 17; the heat-insulating layer 15 is disposed between the airtight tube 17 and the protective tube 13. Preferably, in the present invention, the heat-insulating layer 15 and the airtight tube 17 are provided, the heat-insulating layer 15 absorbs heat, and the airtight tube 17 prevents further heat from entering and affecting the temperature control element 20.

[0040] Furthermore, the heat insulation layer 15 is a polymer heat insulation material, and the airtight tube 17 has a plurality of vacuum cavities. Preferably, the polymer heat insulation material can be made of high foam polypropylene or high foam polypropylene. The vacuum cavity can block heat from entering.

[0041] Furthermore, a plurality of connecting brackets 16 are provided between the protection tube 13 and the spacer tube 17 , and the heat insulating layer 15 is embedded in a space enclosed by the connecting brackets 16 , the spacer tube 17 and the protection tube 13 . The connecting brackets 16 support and fix the spacer tube 17 .

[0042] Furthermore, a plurality of support brackets 19 are provided in the spaced tube 17 , one end of the support bracket 19 is fixedly connected to the inner wall of the spaced tube 17 , and the other end of the support bracket 19 supports the signal transmission tube 18 .

[0043] Furthermore, a power line and a signal transmission line are provided in the signal transmission tube 18 . The power line is connected to the heating wire 14 , the temperature control element 20 and the temperature sensor; the signal transmission line is connected to the temperature control element 20 and the temperature sensor.

[0044] Furthermore, the heating tubes 3 are arranged in a continuous, zigzag pattern within the anchored lawn within the installation area. In actual use, due to the large lawn area, it is often difficult to effectively control the temperature of the soil layer farther from the temperature sensor 1. The present invention arranges the heating tubes 3 in an S-shape, which allows for more effective and uniform heating of the lawn, preventing uneven heating in some areas. By placing two temperature sensors at a distance from each other, the soil temperature in each area can be effectively controlled, allowing temperature circulation in all areas within the lawn.

[0045] In the present invention, a preferred embodiment is:

[0046] See Figure 2 The present invention also provides a construction method, which comprises the following steps:

[0047] A heating tube 3 is provided, and a plurality of temperature sensors 2 are provided on the provided heating tube 3; during the construction of the lawn, the heating tube 3 is buried in the soil below the constructed lawn, and the temperature sensor 2 is located at the root of the constructed lawn to detect the temperature of the root of the lawn in real time; a power supply 1 is provided on one side of the constructed lawn, and the power supply 1 is connected to the heating tube 3.

[0048] In the present invention, a preferred implementation method is: complete the excavation of the implementation base 12, and excavate multiple horizontal gullies in the implementation base 12, the gullies require a horizontal slope of 5%, and a drainage blind ditch 5 is arranged at the bottom of the gully; fill the implementation base 12 with gravel, and form a gravel layer 11 150mm higher than the implementation base 12; lay a first layer of inorganic permeable layer 9 above the gravel layer 11, preferably, the inorganic permeable layer 9 can use permeable geotextile or permeable non-woven fabric; lay medium sand on the first layer of the inorganic permeable layer 9 to form a medium sand layer 10, bury the heating pipe 3 in the medium sand layer 10 and expose the temperature sensor 2, and set a power supply 1 on one side of the lawn, and the power supply 1 is connected to the heating pipe 3 pipeline. Preferably, the thickness of the middle sand layer 10 should be 30 mm; the second layer of the inorganic permeable layer 9 is laid on the middle sand layer 10 and the temperature sensor 2 is exposed, and the upper root zone layer 8 is laid on the inorganic permeable layer 9. The material of the upper root zone layer 8 is a stone-free sand / soil mixture or a sand-organic mixture. The laying thickness should be 100-150 mm and the surface has a slope from the center to the edge to promote surface water runoff; anchor grass 6 is planted in the upper root zone layer 8. The anchor grass 6 can be selected from varieties such as Tifsport, Sealsle2000, and Platinum. After the anchor grass 6 meets the anchoring requirements, a professional anchor grass wire 7 implantation machine is used to implant the anchor grass wire 7 to complete the construction of the anchor lawn.

[0049] The following describes the use of a heating device for anchoring lawns in cold regions and a construction method thereof according to the present invention.

[0050] The present invention receives external temperature information through the temperature sensor 1 and sends the temperature information to the temperature control element 20. The temperature control element 20 judges 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, a heating electrical signal is generated after internal processing and judgment. The temperature control element 20 controls the heating wire 14 to heat up through the heating electrical signal. Under the action of heat conduction, the heating wire 14 dissipates its own higher temperature through the protective tube 13 to the external soil layer, thereby heating the lawn soil layer. 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 20 controls the heating wire 14 to stop heating through the stop heating electrical signal. After completing one heating, the real-time temperature information of the lawn soil layer will continue to be transmitted according to the above process, and ultimately maintain a constant temperature, thereby achieving the effect of intelligently controlling the lawn soil layer, so that the lawn can be continuously kept warm even in winter or cold times. Preferably, in the present invention, a preferred embodiment is as follows: a current transmission line is provided between the signal transmission tube 18 and the heating wire 14, and the temperature control element 20 is connected to the current transmission line. When the temperature of the surrounding soil layer is too low, the temperature control element 20 turns the current transmission line on, heating the heating wire 14. When the temperature of the surrounding soil layer is appropriate or too high, the temperature control element 20 turns the current transmission line off, and the heating wire 14 stops heating. This cycle achieves dynamic control of the growth temperature of the anchored lawn.

A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention.
