Description

Technical Field

[0001] The present invention relates to the technical field of heating belt application, in particular to a patch-type heating belt and a method for installing the heating belt. Background Art

[0002] Heating tape, also known as electric heating tape, is a heating device that uses electrical energy to generate heat. It is mainly used to prevent pipes, containers or other equipment from freezing in low temperature environments, or to maintain the internal medium within a specific temperature range. It converts electrical energy into thermal energy by passing current through the resistance wire inside the heating tape, thereby achieving the purpose of heating.

[0003] In the existing patent literature, there is a patent with publication number CN 213244395 U, entitled "A patch-type heating tape". Although this patent can fix the heating tape by pasting, the heating tape still has the problem of falling off. For example, after long-term use, the adhesive of the heating tape will age, thereby affecting the adhesion. At this time, the heating tape is prone to loosening or falling off. Once it falls off, it is not easy for the staff to notice. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a patch-type heating belt and a method for installing the heating belt. By installing an anti-falling detection mechanism, when the heating belt falls slightly off the film, the display light group at the corresponding position of the anti-falling detection mechanism will go out, thereby prompting that the heating belt here has fallen off, so as to better monitor the status of the heating belt in the later stage.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] A patch-type heating tape, which is a heating tape that is wound and fixed on the outside of the pipeline, with multiple evenly distributed films between the heating tape and the pipeline, and the films are pasted along the length of the pipeline, and all the heating tapes are pasted and fixed on the films, wherein the films are double-sided adhesive;

[0007] An anti-falling detection mechanism is also placed between the heating tape and the pipeline. The anti-falling detection mechanism and the film are parallel to each other and are placed at the top of the pipeline.

[0008] The anti-fall detection mechanism includes an air bag, which is connected to a plurality of air bags evenly distributed, and a heating belt is wound around the air bag between two adjacent air bags; an air cavity is opened inside the air bag, a display light group is installed outside the air bag, and a trigger component electrically connected to the display light group is installed inside the air cavity;

[0009] When the air pressure inside the airbag is higher than the external atmospheric pressure, the trigger component will trigger the display light group to stay on; when the air pressure inside the airbag is equal to or lower than the external atmospheric pressure, the display light group will go out.

[0010] By adopting the above scheme and installing an anti-falling detection mechanism, when the heating tape falls off slightly from the film, the display light group at the corresponding position of the anti-falling detection mechanism will go out, thereby prompting that the heating tape has fallen off, so as to better monitor the status of the heating tape in the later stage.

[0011] As a preferred implementation of a patch-type heating belt, both ends of the airbag are provided with non-enclosed openings.

[0012] With the above solution, in order to facilitate the discharge of gas from the airbag, openings are provided at both ends of the airbag. Once the heating belt falls off, the gas in the airbag will eventually be discharged from the openings at both ends.

[0013] As a preferred embodiment of a patch-type heating belt, the trigger component includes a guide shaft fixed in the air cavity, a slide seat is slidably mounted on the guide shaft, and a spring is mounted on the guide shaft to push the slide seat to move downward; a conductive sheet 1 is fixed on the upper surface of the slide seat, and a conductive sheet 2 corresponding to the position of the conductive sheet 1 is fixed inside the air cavity; when the air pressure in the airbag is higher than the external atmospheric pressure, the air pressure can push the slide seat to overcome the elastic force of the spring, and then the conductive sheet 1 and the conductive sheet 2 contact each other; an air nozzle is opened on the side wall of the airbag, and a sealing cover is provided on the outer side of the air nozzle through a threaded seal.

[0014] Using the above solution, in order to achieve automatic triggering of the light, open the air nozzle and use an air pump to inflate the air cavity to 1.3-1.8 bar through the air nozzle. At this time, the air pressure can push the slide to overcome the elastic force of the spring, and then the conductive sheet 1 and the conductive sheet 2 contact each other, and then the LED lamp emits alternating flashing lights.

[0015] As a preferred implementation of a patch-type heating belt, the display light group includes an LED lamp and a battery, and the switch of the LED lamp is connected to the conductive sheet 1 and the conductive sheet 2 respectively through two wires; wherein the LED lamp can emit alternating flashing lights.

[0016] By adopting the above scheme, in order to realize the on / off control of the LED lamp, when the conductive sheet 1 and the conductive sheet 2 are in contact with each other, the switch of the LED lamp forms a closed loop, and then the LED lamp emits alternating flashing lights to prompt the staff.

[0017] As a preferred embodiment of a patch-type heating belt, an upper pressing portion and a lower pressing portion are further provided between two adjacent airbags inside the airbag, and the upper pressing portion and the lower pressing portion can be closed to each other under the winding and squeezing of the heating belt, thereby realizing the sealing inside the airbag; wherein, the contact surface between the upper pressing portion and the lower pressing portion is mutually meshing sealing teeth.

[0018] By adopting the above scheme, in order to achieve the air bag being pressed and sealed by the heating belt, the upper pressing part and the lower pressing part can be closed to each other under the winding and squeezing of the heating belt, thereby achieving the sealing inside the air bag. Once the heating belt falls off, the gas will leak from the upper pressing part and the lower pressing part.

[0019] A method for installing a heating tape, which uses the above-mentioned patch-type heating tape for installation, and the specific operation steps are as follows:

[0020] S1. Paste the film on the outside of the pipeline along the length direction of the pipeline, and place the anti-falling detection mechanism at the top of the pipeline, and make the anti-falling detection mechanism parallel to the direction of the film;

[0021] S2. Wind the heating tape tightly and stick it on the film. When winding the heating tape, the anti-falling detection mechanism should be wound together. At this time, the heating tape is tightly wound and squeezed on the airbags of two adjacent airbags;

[0022] S3. Open the air nozzle and use the air pump to inflate the air cavity to 1.3-1.8 bar through the air nozzle. At this time, the air pressure can push the slide to overcome the elastic force of the spring, and then the conductive sheet 1 and the conductive sheet 2 come into contact with each other, and then the LED lamp emits alternating flashing lights;

[0023] S4. If the heating belt becomes loose or falls off, the high-pressure gas in the air cavity will leak out from between the upper and lower compression parts until the air pressure in the air cavity is equal to the external air pressure. At this time, the indicator light group goes out, and the staff should deal with it in time.

[0024] After adopting the above technical solution, the beneficial effects of the present invention are:

[0025] 1. By installing an anti-falling detection mechanism, when the heating tape falls off slightly from the film, the display light group at the corresponding position of the anti-falling detection mechanism will go out, so as to remind that the heating tape has fallen off, so as to better monitor the status of the heating tape in the later stage;

[0026] 2. In order to facilitate the discharge of gas from the airbag, openings are opened at both ends of the airbag. Once the heating cable falls off, the gas in the airbag will eventually be discharged from the openings at both ends;

[0027] 3. In order to achieve automatic triggering of the light, open the air nozzle and use an air pump to inflate the air cavity to 1.3-1.8 bar through the air nozzle. At this time, the air pressure can push the slide to overcome the elastic force of the spring, and then the conductive sheet 1 and the conductive sheet 2 contact each other, and then the LED lamp emits alternating flashing lights;

[0028] 4. In order to realize the on / off control of the LED lamp, when the conductive sheet 1 and the conductive sheet 2 are in contact with each other, the switch of the LED lamp forms a closed loop, and then the LED lamp emits alternating flashing lights to remind the staff;

[0029] 5. In order to achieve the air bag being pressed and sealed by the heating belt, the upper pressing part and the lower pressing part can be closed to each other under the winding and squeezing of the heating belt, so as to achieve the sealing inside the air bag. Once the heating belt falls off, the gas will leak from the upper pressing part and the lower pressing part. BRIEF DESCRIPTION OF THE DRAWINGS
