[0026] By installing one section of temperature sensor 6 and two sections of temperature sensor 7 at the inner wall of outer tube shell 1 close to upper and lower section electric heating wire 2 respectively, the temperature of different depth of soil can be monitored in real time, to provide accurate temperature data for temperature controller 5, to ensure the accurate control of heating process.
[0027] The setting of heat conduction core 4 effectively transfers the heat generated by electric heating wire 2 to outer tube shell 1, and then to soil, improves the efficiency of heat conduction, so that soil can quickly and uniformly reach the required temperature.
[0028] In this embodiment, the outer wall of the outer shell 1 is provided with a plurality of clamping claws 8 from top to bottom, and the clamping claws 8 are inclined. The inclined arrangement of the clamping claws 8 enhances the stability and fixity of the warming pipe in the soil, prevents the warming pipe from shifting or tilting during use, ensures that the warming pipe can be firmly installed in the soil, and improves the reliability and durability of use.
[0029] Specifically, the temperature controller 5 is provided with a circuit board 51 inside the shell, and the bottom of the circuit board 51 is provided with a heat insulation plate 52. The heat insulation plate 52 effectively isolates the heat generated by the circuit board 51, prevents the heat from being transmitted to the shell of the temperature controller 5, protects the internal elements of the temperature controller 5 from overheating, and improves the stability and service life of the temperature controller.
[0030] Further, the shell of the temperature controller 5 is provided with a wire sleeve 54 at the bottom, and the bottom of the circuit board 51 is connected to a one-way line 55 and a two-way line 56, both of which pass through the wire sleeve 54 and are respectively connected to the upper and lower electric heating wires 2. The design of the wire sleeve 54 provides protection and fixation for the line, prevents the line from being pulled or damaged during use, ensures the reliable connection between the electric heating wire 2 and the circuit board 51, and guarantees the normal work of the heating system.
[0031] Further, the shell of the temperature controller 5 is provided with a control panel 57, and the circuit board 51 is electrically connected to the control panel 57 through the line. The setting of the control panel 57 enables the user to conveniently set and adjust the working parameters of the warming pipe, such as heating temperature and heating time, realizes the intelligent control of the warming pipe, and improves the convenience and flexibility of use.
[0032] Further, the shell of the temperature controller 5 is provided with a protective layer 53 on the inner wall, and the protective layer 53 is made of rubber material. The protective layer 53 made of rubber material has good insulation and corrosion resistance, which can protect the internal elements of the temperature controller 5 from external environment interference and damage, and improve the reliability and durability of the temperature controller.
[0033] Further, the electric heating wire 2 is in a spiral structure and is wound on the outer wall of the winding shaft 3. The spiral structure of the electric heating wire 2 increases the contact area with the winding shaft 3, improves the efficiency of heat transfer, and enables the heat generated by the electric heating wire 2 to be more evenly transferred to the heat-conducting core 4 and the soil, realizing efficient heating of the soil.
[0034] Further, the heat-conducting core 4 is made of copper material, and the heat-insulating plate 52 is made of perlite material. The heat-conducting core 4 made of copper material has good heat-conducting performance, can rapidly transmit the heat generated by the electric heating wire 2 to the soil, and improves the heating efficiency. The heat-insulating plate 52 made of perlite material has good heat-insulating performance, can effectively insulate the heat generated by the circuit board 51, protects the internal elements of the temperature controller 5, and improves the reliability and safety of the whole soil temperature gradient heating pipe.
[0035] In use of the soil temperature gradient heating pipe, the heating pipe mainly comprises an outer pipe shell 1, a winding shaft 3, an electric heating wire 2, a heat-conducting core 4 and a temperature controller 5. The electric heating wire 2 is divided into two sections, and is arranged on the outer wall of the winding shaft 3, and can work independently or cooperatively. The inner wall of the outer pipe shell 1 is provided with a first temperature sensor 6 and a second temperature sensor 7 near the upper and lower sections of the electric heating wire 2. The temperature controller 5 is installed on the top of the outer pipe shell 1, and comprises a circuit board 51, a heat-insulating plate 52, a wire sleeve 54, a protective layer 53 and the like, and is interacted with the user through a control panel 57.
[0036] When the soil needs to be heated, the user sets the working parameters such as heating temperature and heating time through the control panel 57. After the circuit board 51 receives the instruction, the electric heating wire 2 is controlled to be powered on. Since the electric heating wire 2 has a spiral structure, the contact area with the winding shaft 3 is increased, and the heat transfer efficiency is improved. The heat generated by the electric heating wire 2 is transmitted to the outer pipe shell 1 through the heat-conducting core 4, and then is transmitted to the soil. The heat-conducting core 4 is made of copper material, has good heat-conducting performance, and can rapidly transmit the heat to the soil.
[0037] The first temperature sensor 6 and the second temperature sensor 7 monitor the temperature of the soil at different depths in real time, and transmit the temperature data to the circuit board 51. The circuit board 51 compares the received temperature data with the preset heating temperature, adjusts the heating power of the electric heating wire 2 to realize accurate control of the soil temperature. If the soil temperature is lower than the preset temperature, the circuit board 51 increases the heating power of the electric heating wire 2; if the soil temperature is higher than the preset temperature, the circuit board 51 reduces or closes the heating power of the electric heating wire 2.
[0038] The outer wall of the outer shell 1 is provided with a plurality of clamping claws 8 from top to bottom, the clamping claws 8 are inclined, which enhances the stability and fixity of the temperature increasing pipe in the soil, and prevents the temperature increasing pipe from being displaced or inclined during use. The heat insulation plate 52 in the temperature controller 5 effectively isolates the heat generated by the circuit board 51, preventing the heat from being transmitted to the shell of the temperature controller 5, and protecting the internal elements of the temperature controller 5 from overheating. The design of the wire sleeve 54 provides protection and fixation of the line, preventing the line from being pulled or damaged during use, and ensuring the reliable connection between the electric heating wire 2 and the circuit board 51. The protective layer 53 is made of rubber material, which has good insulation and corrosion resistance, and can protect the internal elements of the temperature controller 5 from external environment interference and damage.
[0039] Finally, it should be noted that the temperature controller 5 in the embodiment, the electronic components in the above components are all general standard components or components known to those skilled in the art, the structure and principle are known to those skilled in the art through technical manual or through conventional experimental method, in the idle place of the device, all the above electrical components are connected through wires, the specific connection means should refer to the working order of the electrical components in the above working principle to complete the electrical connection, which are all known technology in the art.
