[0019] Embodiment

[0021] The heat preservation sheet is successively divided into a heating layer 2, a heat exchange layer 3, a heat preservation layer 4, and a protective layer 5 from inside to outside. The heat preservation layer is made of high-temperature resistant high-silica oxygen or ceramics. The protective layer is a coating made of glass fiber. The heating layer 2 is provided with a temperature sensor 10. The heat exchange layer 3 is provided with a heat exchange cavity. The heat exchange cavity is provided with a medium inlet pipe 8 and a medium outlet pipe 9. The medium inlet pipe 8 is connected to a medium storage tank through a liquid inlet pipe. A liquid inlet pump is provided on the liquid inlet pipe. The temperature sensor 10 is electrically connected to the liquid inlet pump. The heat preservation sleeve is composed of two mutually cooperating heat preservation sheets. The two heat preservation sheets are detachably connected, facilitating sleeving the heat preservation sleeve on the pipeline 1 to be heat-preserved. During operation, the heating layer 2 heats up. The temperature sensor 10 senses the temperature at the pipeline 1. When the temperature is low, the heating layer 2 continuously heats. When the temperature is too high, the medium is passed through the medium inlet pipe 8 into the heat exchange layer 3 through the liquid inlet pump to exchange heat with the heating layer 2, reducing the temperature. Thus, the heat preservation sleeve has a temperature adjustment function.

[0022] A plurality of the heat preservation sleeves are connected in series. The adjacent two heat preservation sleeves are detachably connected. The setting here can select a plurality of heat preservation sleeves to be connected in series according to the length of the pipeline 1 to be heat-preserved, playing a heat preservation role.

[0023] The medium inlet pipe 8 and the medium outlet pipe 9 are respectively located at both ends of the heat preservation sheet. The inner diameters and outer diameters of the medium inlet pipe 8 and the medium outlet pipe 9 are the same. Threads are provided on the outer walls of the medium inlet pipe 8 and the medium outlet pipe 9. A sealing gasket I 16 is provided in a circle at one end of the medium inlet pipe 8 close to the heat preservation sheet. A sealing pipe 14 is provided on the medium outlet pipe 9. The two ends of the sealing pipe 14 are in threaded cooperation with the medium outlet pipe 9. A sealing gasket II 15 is provided in a circle at the end of the medium outlet pipe 9 away from the heat preservation sheet. The sealing gasket II 15 is always located inside the sealing pipe 14. When the heat preservation sleeves are connected in series, the medium inlet pipe 8 of one heat preservation sleeve is connected to the medium outlet pipe 9 of the adjacent heat preservation sleeve. Rotate the sealing pipe 14 to move it along the medium outlet pipe 9 towards the medium inlet pipe 8 until one end of the sealing pipe 14 abuts against the sealing gasket I 16. At this time, the other end of the sealing pipe 14 contacts the sealing gasket II 15, avoiding water seepage at the interface and being convenient for installation and disassembly. The sealing gasket I and the sealing gasket II are both high-temperature resistant rubber or silicone gaskets.

[0024] An electric heating wire is provided in the heating layer 2. Wiring terminals are provided at both ends of the heating layer 2. The wiring terminals are connected to the electric heating wire. The electric heating wire is connected to an external power supply through the wiring terminals. When the heat preservation sleeves are connected in series, the adjacent wiring terminals of each electric heating wire are connected in series through wires.

[0025] A controller 11 is provided on multiple series-connected heat-insulating sleeves. The liquid inlet pipe is connected to the medium inlet pipe 8 of the heat-insulating sleeve at the end. The liquid inlet pump and the temperature sensor 10 are electrically connected to the controller 11. The controller 11 controls the circulation of the medium in the heat exchange layer 3 according to the data transmitted by the temperature sensor 10, improving the degree of automation. A switch is provided on the circuit of the external power supply and the electric heating wire. The switch is connected to the controller. The controller controls the on-off of the switch according to the data of the temperature sensor, and then controls whether the electric heating wire heats or not.

[0026] On one side of the heat-insulating sheet, a plurality of first connecting blocks 6 are fixedly connected. The plurality of first connecting blocks 6 are evenly distributed along the length direction of the heat-insulating sheet. On the other side of the heat-insulating sheet, a plurality of second connecting blocks 12 are fixedly connected. The plurality of second connecting blocks 12 are evenly distributed along the length direction of the heat-insulating sheet. The first connecting blocks 6 on two mutually cooperating heat-insulating sheets correspond one by one and are hinged through a hinge shaft 7. The second connecting blocks 12 on two mutually cooperating heat-insulating sheets correspond one by one and are detachably connected through bolts 13. This facilitates the installation and disassembly of the two heat-insulating sheets.

[0027] Working principle: During operation, the heating layer 2 heats up. The temperature sensor 10 senses the temperature at the pipeline 1. When the temperature is low, the heating layer 2 continuously heats. When the temperature is too high, the heating stops and the medium is passed through the medium inlet pipe 8 into the heat exchange layer 3 by the liquid inlet pump to exchange heat with the heating layer 2 to reduce the temperature, enabling the heat-insulating sleeve to have a temperature adjustment function. Additionally, according to the length of the pipeline 1 that needs to be insulated, multiple heat-insulating sleeves can be selected to be connected in series to play a role in heat preservation and temperature adjustment. Specifically, when the heat-insulating sleeves are connected in series, the medium inlet pipe 8 of one heat-insulating sleeve is connected to the medium outlet pipe 9 of the adjacent heat-insulating sleeve. Rotate the sealing pipe 14 to move it along the medium outlet pipe 9 towards the medium inlet pipe 8 until one end of the sealing pipe 14 abuts against the first sealing gasket 16. At this time, the other end of the sealing pipe 14 contacts the second sealing gasket 15 to prevent water seepage at the interface. The adjacent terminal blocks of the electric heating wires of each heat-insulating sleeve are connected in series through wires, and the terminal block at the end is connected to the power supply.

[0028] In the initial stage of heating, the temperature of the pipeline itself is relatively low. The heating layer heats the pipeline, reducing the consumption of some heat during the process of hot water entering the pipeline, avoiding a large temperature difference in the heating and poor heating effect. In addition, when the temperature stabilizes, the heating of the heating layer can be stopped in time to avoid waste of energy and too high temperature. Moreover, when the temperature is too high or heating stops, a cooling medium can be introduced into the heat exchange layer to take away the heat and be applied to other aspects, such as domestic water in winter, improving the utilization rate of energy and reducing waste.

[0029] The controller is a single-chip microcomputer controller, and a PLC controller can be adopted. It is communicatively connected to a temperature sensor, a switch and a liquid inlet pump through a conversion module, and the conversion module adopts an RS485 communication module. The single-chip microcomputer controller includes a data processing module and a display module communicatively connected thereto. The data processing module transmits the data of the temperature sensor collected in real time to the display for immediate display, and controls the heating of the electric heating wire and the inflow and outflow of the medium in the heat exchange layer according to the analysis of each data.

[0030] Regarding the single-chip microcomputer controller in this embodiment, this application does not improve the programmable program of the controller, but only utilizes its existing control program and principle to implement the functions of data calculation, analysis and comparison; regarding the control program and principle involved, reference can be made to the product manual of the controller or prior art materials, which are all prior art.

[0031] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
