[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] See also Figure 1-Figure 4The solar-specific electric heating belt comprises a heating belt body 10. The heating belt body 10 is provided with a heating element 12 for converting electric energy into heat energy, an insulating layer 13 for isolating the heating element 12 from the external environment and an external protective layer 14 for protection in sequence from the inside to the outside. A power connection line 11 is connected to one end of the heating element 12. The end of the power connection line 11 is connected to a power source for transmitting electric energy to the heating element 12 for heating. A plurality of positioning ring grooves 15 are evenly spaced on the external protective layer 14. The diameter of the external protective layer 14 at the location where the positioning ring grooves 15 are provided is higher than that at other locations. In order to be able to open a positioning ring groove 15 with a certain available depth on the external protective layer 14, an elastic positioning ring band 16 is elastically tightened inside the positioning ring groove 15. The elastic positioning ring band 16 is evenly provided with a plurality of slots 18 and a plurality of telescopic connection bases 19 in an annular shape, and a bayonet pin 20 or a suction cup 21 is installed at the outer end of the telescopic connection base 19 at different positions, wherein the bayonet pin 20 can be engaged with the slot 18, that is, when the adjacent heating belt bodies 10 need to be closely and tightly connected, the bayonet pin 20 on the corresponding elastic positioning ring band 16 is engaged with the slot 18 to achieve a certain degree of detachable connection. When the heating belt body 10 needs to be fixed at the heating position in use, the suction cup 21 is extended outward through the elastic action of the telescopic connection base 19, so that its end is adsorbed at the corresponding position, thereby ensuring the rapid and immediate fixation of the heating belt body 10, that is, to a certain extent, the function of rapid fixation of the heating belt body 10 is improved, the installation cost is reduced, and the scope of application is increased.

[0018] In the embodiment of the present invention, the heating element 12 is made of a high thermal conductivity material, which can convert electrical energy into thermal energy and transfer the thermal energy to a medium that needs to be heated (generally water). The insulating layer 13 covers and wraps the outside of the heating element 12, and the external protective layer 14 wraps the outside of the insulating layer 13 to ensure that each layer is fully isolated.

[0019] When the telescopic connection base 19 is in a free state, the bayonet 20 and the suction cup 21 disposed at the outer end of the telescopic connection base 19 are kept to be retracted into the positioning ring groove 15, that is, to prevent them from protruding outwards and affecting the normal installation and connection of the heating belt body 10;

[0020] At the same time, a plurality of elastic connecting sections 17 are arranged at equal intervals in a ring shape on the elastic positioning ring band 16. The elastic expansion and contraction effect of the elastic connecting sections 17 is utilized to keep the elastic positioning ring band 16 able to be installed and removed in the positioning ring groove 15. It should be noted that the elastic effect of the elastic connecting section 17, after it is mounted on the positioning ring groove 15, will not have too much influence on the subsequent clamping connection between the pin 20 and the clamping groove 18, and the adsorption and positioning between the suction cup 21 and the fixed object. In general, the heating belt body 10 is positioned by the suction cup 21. Due to the elastic setting of the bottom telescopic connecting base 19, it itself has a certain buffering property. However, due to the light overall weight of the heating belt body 10, the local expansion and contraction effect of the elastic connecting section 17 and the telescopic connecting base 19 will not affect the positioning of the heating belt body 10.

[0021] In one embodiment of the present invention, the telescopic connection base 19 includes a telescopic hole 22 fixed on the elastic positioning ring band 16, the top of the telescopic hole 22 is set to an opening shape, and a telescopic rod 25 is telescopically arranged inside the telescopic hole 22. The outer end of the telescopic rod 25 is connected to a connecting rod 26, and the connecting rod 26 is respectively fixed to the pin 20 or the suction cup 21. The other end of the telescopic rod 25 extends into the telescopic hole 22 to install a limit block 24. The area of ​​the limit block 24 is larger than the opening of the telescopic hole 22, that is, it is used to prevent the telescopic rod 25 from detaching from the telescopic hole 22. A plurality of springs 23 are evenly connected to the bottom of the limit block 24. The elastic action of the spring 23 is utilized to provide telescopic movement capability for the pin 20 and the suction cup 21 at the top of the connecting rod 26.

[0022] The working principle of the utility model is: in the idle part of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. When heating the water tank, etc., according to the heating area, select the appropriate number of heating belt bodies 10 for installation. When the heating belt body 10 is installed, according to the distribution range and requirements, if it is heating If the belt bodies 10 need to be connected and distributed, the pin 20 on the elastic positioning ring belt 16 is stretched outward to engage with the slot 18 on the elastic positioning ring belt 16 on the adjacent side, and then the connection and tightening distribution between adjacent heating belt bodies 10 are ensured under the engagement of multiple elastic positioning ring belts 16 and the pin 20. If the heating belt body 10 needs to be fixed on a fixed object such as a water tank, the suction cup 21 is directly pulled outward to adsorb it on the fixed object, and then the heating belt body 10 is quickly and stably installed under the adsorption of multiple suction cups 21.

[0023] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
