Description

Technical Field

[0001] The utility model relates to the technical field of heat tracing band heating, in particular to an external heating device for pipes based on a self-regulating heat tracing band. Background Technique

[0002] A heat tracing band is an electrothermal device for heating, usually composed of one or more electric heating wires or electric heating films, and is externally wrapped with insulating materials and protective layers. The heat tracing band can be used in various occasions, such as pipe heat preservation, anti-freezing, heating, snow melting, ice prevention, etc.

[0003] In the existing patent literature, there is a patent with a publication number of CN 114205933 B and a name of "A self-regulating electrothermal heat tracing band with a pipe bundling device". This patent mainly uses an elastic clamping plate to clamp and fix the heat tracing band on the outer surface of the pipe. However, in actual application, when the liquid in the pipe flows, certain vibrations will occur. These vibrations will be transmitted to the clamping plate through the pipe. At this time, the spring that pushes the clamping plate will be affected by the vibrations and change the clamping force of the clamping plate. Over time, the heat tracing band on the side of the pipe will gradually slide to the bottom, and then the pipe will be unevenly heated. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an external heating device for pipes based on a self-regulating heat tracing band. This device can evenly fix the self-regulating heat tracing band on the outside of the pipe through a restraint band assembly. Even when affected by the vibration of the pipe, the positions of each self-regulating heat tracing band will not change due to the vibration feeling, and its heating uniformity is better and the overall stability is higher.

[0005] To solve the above technical problems, the technical solution of the utility model is realized as follows:

[0006] An external heating device for pipes based on a self-regulating heat tracing band includes a restraint band assembly, a main quick-release installation mechanism, and an auxiliary quick-release installation mechanism; both ends of the restraint band assembly are detachably installed on the main quick-release installation mechanism and the auxiliary quick-release installation mechanism respectively. The main quick-release installation mechanism and the auxiliary quick-release installation mechanism connect the restraint band assembly together after surrounding the pipe for one week. Self-regulating heat tracing bands are detachably installed on the restraint band assembly and are distributed in a circumferential array around the pipe; the restraint band assembly includes an elastic band, and both ends of the elastic band are respectively connected with buckle fasteners, and the buckle fasteners can be sleeved on the main quick-release installation mechanism or the auxiliary quick-release installation mechanism; a plurality of evenly distributed elastic positioning buckles are connected to the outer side of the elastic band, and the self-regulating heat tracing band is installed on the elastic positioning buckles and is elastically fixed by the elastic positioning buckles.

[0007] With the above solution, the device can evenly fix the self-regulating heating cable on the outer side of the pipeline through the restraint belt assembly. Even if the pipeline vibrates, the positions of the self-regulating heating cables will not change due to the vibration, resulting in better heating uniformity and higher overall stability. Secondly, since the self-regulating heating cable is directly fixed in the elastic positioning buckle, its disassembly and assembly are also simpler.

[0008] As a preferred embodiment of the external heating device for pipelines based on self-regulating heating cables, the main quick-release installation mechanism includes a first outer housing. A fixed docking link is installed on the outer side wall of the first outer housing. At one end of the first outer housing away from the fixed docking link, a movable sleeve link is installed, and the buckle can be sleeved on the movable sleeve link. The movable sleeve link penetrates into the interior of the first outer housing and is slidably connected to a guide rod fixed inside the first outer housing. A spring for pushing the movable sleeve link towards the fixed docking link is sleeved on the guide rod. An anti-extrusion block is also fixed on the movable sleeve link on the same side as the spring.

[0009] In addition, a buzzer is installed inside the first outer housing. One side of the buzzer is connected to a control switch. Two trigger guides are electrically connected beside the control switch. A guide piece corresponding to the positions of the two trigger guides is fixed on the movable sleeve link. A power supply is also electrically connected beside the buzzer.

[0010] With the above solution, in order to achieve automatic alarm when the self-regulating heating cable falls off, an alarm structure is set in the main quick-release installation mechanism. When the movable sleeve link is pulled by the buckle to compress the spring, at this time, the two trigger guides and the guide piece are not in contact with each other. Then, after starting the control switch, since the two trigger guides do not form a closed circuit, the buzzer does not sound at this time. When the elastic band is accidentally broken, the movable sleeve link rebounds and resets under the push of the spring. At this time, the two trigger guides and the guide piece are in contact with each other. Then, after starting the control switch, since the two trigger guides form a closed circuit, the buzzer sounds at this time.

[0011] As a preferred embodiment of the external heating device for pipelines based on self-regulating heating cables, the auxiliary quick-release installation mechanism includes a second outer housing. A fixed docking pipe is installed on the outer side wall of the second outer housing, and the fixed docking pipe can be docked with the fixed docking link. At one end of the second outer housing away from the fixed docking pipe, a fixed sleeve link is installed, and the buckle can be sleeved on the fixed sleeve link.

[0012] With the above solution, in order to achieve the installation connection between the main quick-release installation mechanism and the auxiliary quick-release installation mechanism, during installation, only the fixed docking link needs to be docked with the fixed docking pipe. Under the elastic tension of the elastic band, the entire restraint belt assembly, the main quick-release installation mechanism, and the auxiliary quick-release installation mechanism will be fixed on the pipeline.

[0013] As a preferred embodiment of an external heating device for a pipe based on a self-regulating heating cable, damping is provided on the surfaces of the fixed docking connecting rod, the movable sheathing connecting rod, and the fixed sheathing connecting rod.

[0014] With the above solution, in order to further improve the stability after connection, damping is provided on the surface of the connection to increase the friction force during connection.

[0015] As a preferred embodiment of an external heating device for a pipe based on a self-regulating heating cable, a plurality of sound amplification holes are provided on the surface of the outer casing one at the position corresponding to the buzzer.

[0016] With the above solution, in order to further improve the sound amplification effect, sound amplification holes are provided in the outer casing one at the location of the buzzer to facilitate the diffusion of sound.

[0017] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0018] 1. The device can evenly fix the self-regulating heating cable on the outside of the pipe through the restraint belt assembly. Even if the pipe vibrates, the positions of the self-regulating heating cables will not change due to the vibration, and its heating uniformity is better and the overall stability is higher. Secondly, since the self-regulating heating cable is directly fixed in the elastic positioning buckle, its disassembly and assembly are also simpler.

[0019] 2. In order to achieve automatic alarm when the self-regulating heating cable falls off, an alarm structure is provided in the main quick-release installation mechanism. When the movable sheathing connecting rod is pulled by the belt buckle to compress the spring, at this time, the two trigger guide heads and the guide piece are not in contact with each other. Then, after starting the control switch, since the two trigger guide heads do not form a closed circuit, the buzzer does not sound at this time. When the elastic belt is accidentally broken, the movable sheathing connecting rod rebounds and resets under the push of the spring. At this time, the two trigger guide heads and the guide piece are in contact with each other. Then, after starting the control switch, since the two trigger guide heads form a closed circuit, the buzzer sounds at this time.

[0020] 3. In order to achieve the installation connection between the main quick-release installation mechanism and the auxiliary quick-release installation mechanism, during installation, only the fixed docking connecting rod needs to be docked with the fixed docking connecting pipe. Under the elastic tension of the elastic belt, the entire restraint belt assembly, the main quick-release installation mechanism, and the auxiliary quick-release installation mechanism will be fixed on the pipe.

[0021] 4. In order to further improve the stability after connection, damping is provided on the surface of the connection to increase the friction force during connection.

[0022] 5. In order to further improve the sound amplification effect, sound amplification holes are provided in the outer casing one at the location of the buzzer to facilitate the diffusion of sound. Description of the Drawings

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 6 As shown, a pipeline external heating device based on a self-controlling temperature heating tape comprises a restraining belt assembly 1, a main quick-release mounting mechanism 2 and an auxiliary quick-release mounting mechanism 3; the two ends of the restraining belt assembly 1 are detachably mounted on the main quick-release mounting mechanism 2 and the auxiliary quick-release mounting mechanism 3 respectively, the main quick-release mounting mechanism 2 and the auxiliary quick-release mounting mechanism 3 connect the restraining belt assembly 1 together after being wrapped around the pipeline 4 for one circle, and the restraining belt assembly 1 is detachably mounted with a self-controlling temperature heating tape 5 distributed in an array around the circumference of the pipeline 4; the restraining belt assembly 1 comprises an elastic belt 101, the two ends of the elastic belt 101 are respectively connected to a buckle 102, and the buckle 102 can be mounted on the main quick-release mounting mechanism 2 or the auxiliary quick-release mounting mechanism 3; the outer side of the elastic belt 101 is connected to a plurality of evenly distributed elastic positioning buckles 103, the self-controlling temperature heating tape 5 is mounted on the elastic positioning buckle 103 and is elastically tightened by the elastic positioning buckle 103.

[0036] The device can evenly fix the self-regulating temperature heating belt 5 on the outside of the pipe 4 through the restraining belt assembly 1. Even if the pipe 4 vibrates, the position of each self-regulating temperature heating belt 5 will not change due to the vibration, and its heating uniformity is better and the overall stability is higher. Secondly, since the self-regulating temperature heating belt 5 is directly fixed in the elastic positioning buckle 103, it is also easier to disassemble and assemble.

[0037] like Figure 7 、 Figure 9 As shown, the main quick-release installation mechanism 2 includes an outer shell 201, and a fixed docking link 202 is installed on the outer side wall of the outer shell 201; a movable sleeve connecting rod 203 is installed at one end of the outer shell 201 away from the fixed docking link 202, and the belt buckle 102 can be sleeved on the movable sleeve connecting rod 203; the movable sleeve connecting rod 203 passes through the interior of the outer shell 201 and is slidably connected to a guide rod 204 fixed to the interior of the outer shell 201, and the guide rod 204 is sleeved with a spring 205 for pushing the movable sleeve connecting rod 203 to move toward the location of the fixed docking link 202; an anti-extrusion block 206 located on the same side of the spring 205 is also fixed to the movable sleeve connecting rod 203.

[0038] In addition, a buzzer 207 is installed inside the outer casing 201, and a control switch 208 is connected to one side of the buzzer 207; two trigger contacts 209 are electrically connected beside the control switch 208, and a guide piece 210 corresponding to the positions of the two trigger contacts 209 is fixed on the movable sleeve connecting rod 203; a power supply 211 is also electrically connected beside the buzzer 207.

[0039] In order to achieve automatic alarm when the self-regulating heating cable 5 falls off, an alarm structure is provided in the main quick-release installation mechanism 2; when the movable sleeve connecting rod 203 is pulled by the buckle 102 to compress the spring 205, at this time, the two trigger contacts 209 and the guide piece 210 are not in contact with each other. Then, after the control switch 208 is started, since the two trigger contacts 209 do not form a closed circuit, the buzzer 207 does not sound at this time; when the elastic band 101 is accidentally broken, the movable sleeve connecting rod 203 rebounds and resets under the push of the spring 205. At this time, the two trigger contacts 209 and the guide piece 210 are in contact with each other. Then, after the control switch 208 is started, since the two trigger contacts 209 form a closed circuit, the buzzer 207 sounds at this time.

[0040] As Figure 8 shown, the auxiliary quick-release installation mechanism 3 includes an outer casing 301 of the second type. A fixed docking pipe 302 is installed on the outer side wall of the outer casing 301 of the second type, and the fixed docking pipe 302 can be docked with the fixed docking link 202; a fixed sleeve connecting rod 303 is installed at one end of the outer casing 301 of the second type away from the fixed docking pipe 302, and the buckle 102 can be sleeved on the fixed sleeve connecting rod 303.

Under the elastic tension of the elastic band 101, the entire restraint belt assembly 1, the main quick-release installation mechanism 2, and the auxiliary quick-release installation mechanism 3 will be fixed on the pipeline 4.

[0042] As Figures 7 to 9 shown, damping is provided on the surfaces of the fixed docking link 202, the movable sleeve connecting rod 203, and the fixed sleeve connecting rod 303. In order to further improve the stability after connection, damping is provided on the surface of the connection part to increase the friction during connection.

[0043] As Figure 6 shown, a plurality of sound amplification holes are opened on the surface of the outer casing 201 corresponding to the position where the buzzer 207 is located. In order to further improve the sound amplification effect, sound amplification holes are opened on the outer casing 201 where the buzzer 207 is located to facilitate the diffusion of sound.

[0044] The working principle of the present utility model:

[0045] During application, a set of restraint belt assemblies 1, main quick-release mounting mechanisms 2, and auxiliary quick-release mounting mechanisms 3 are installed at regular intervals outside the pipeline 4.

[0046] During installation, an elastic belt 101 that matches the diameter of the pipeline 4 is selected. The belt buckles 102 at both ends of the elastic belt 101 are respectively sleeved on the movable sleeving connecting rod 203 and the fixed sleeving connecting rod 303. Then, after the elastic belt 101 is wound around the pipeline 4 for one week, the fixed docking connecting rod 202 and the fixed docking connecting pipe 302 are docked with each other. Under the elastic tension of the elastic belt 101, the entire restraint belt assembly 1, the main quick-release mounting mechanism 2, and the auxiliary quick-release mounting mechanism 3 will be fixed on the pipeline 4. Finally, the self-regulating heating cable 5 is installed in the elastic positioning buckle 103. At this time, the self-regulating heating cable 5 is elastically fastened by the elastic positioning buckle 103, and the installation of the self-regulating heating cable 5 can be completed.

[0047] During use, the control switch 208 is turned on. When the movable sleeving connecting rod 203 is pulled by the belt buckle 102 to compress the spring 205, at this time, the two trigger guides 209 and the guide piece 210 are not in contact with each other. Since the two trigger guides 209 do not form a closed circuit, the buzzer 207 does not sound at this time. When the elastic belt 101 is accidentally torn, the movable sleeving connecting rod 203 rebounds and resets under the push of the spring 205. At this time, the two trigger guides 209 and the guide piece 210 are in contact with each other. Since the two trigger guides 209 form a closed circuit, the buzzer 207 sounds at this time to warn the staff to go and deal with it.

[0048] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
