Protective plastic pipe with fireproof function

Abstract

The protective plastic pipe with the fireproof function comprises a main body mechanism and a cooling mechanism, all second screws are rotated on the inner side of a sleeve frame, so that the bottoms of the second screws extrude a base, and a fireproof frame below the base is pushed to the position where the fireproof frame is attached to the outer wall of a main pipe. When the fireproof frame and the plugging cavity column are heated at a high temperature, kerosene packaged in the plugging cavity column expands greatly after being heated, so that the plugging cavity column made of a glass material is broken, and the plugging cavity column loses the plugging capability to the fireproof frame at the moment; the cooling liquid in the fireproof frame naturally permeates into the cavity formed between the main pipe and the sleeve frame to wet and cool the outer wall of the main pipe, so that the deformation and damage speed of a pipe body when the main pipe is burnt by high temperature is effectively increased, longer time for taking emergency measures is reserved for external personnel, and the fireproof purpose is achieved.

[0017] The present invention has at least the following beneficial effects:

[0018] 1. When the present invention is in use, by setting a fireproof frame which is movably connected between a sleeve frame and a main pipe, the fireproof frame is filled with a coolant, and a plugging cavity column is fixedly connected to one side inside the fireproof frame. The plugging cavity column is made of glass and filled with kerosene.

Rotate each second screw inside the sleeve frame to make the bottom of the second screw press the base, and push the fireproof frame below the base to the position where the fireproof frame fits the outer wall of the main pipe. During long-term use, when a fire occurs externally, the high temperature heats the fireproof frame and the plugging cavity column. Since the kerosene filled in the plugging cavity column will expand significantly after heating up, it will burst the plugging cavity column made of glass. At this time, the plugging cavity column loses its plugging ability for the fireproof frame, and the coolant in the fireproof frame naturally penetrates into the cavity formed between the main pipe and the sleeve frame to moisten and cool the outer wall of the main pipe, thereby effectively prolonging the deformation and damage speed of the pipe body when the main pipe is burned by high temperature, and thus leaving a longer time for external personnel to take emergency measures to achieve the purpose of fire prevention;

[0019] 2. By setting a knob, a pressing ring is fixedly connected to one side of the knob, and a first screw is fixedly connected to the inner side of the pressing ring. The outer side of the bottom end of the first screw is threadedly connected with a nut, which can effectively facilitate personnel to directly hold and rotate;

[0020] 3. By setting a gasket, the gasket is movably connected to the first screw, and the gasket is located between the pressing ring and the adapter piece, which can effectively reduce the loosening amplitude of the first screw during long-term use and ensure the stability of the first screw;

[0021] 4. By setting a slide bar, the sleeve frame is slidably connected to the outer side of the slide bar, and a base is fixedly connected to one end of the slide bar, which can effectively ensure the stability of the position of the base. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-7

[0032] Embodiment 1

[0033] A protective plastic pipe with fire prevention function, comprising a main body mechanism 1 and a cooling mechanism 2:

[0034] The main body mechanism 1 includes a main pipe 101, a connecting pipe 102 is fixedly connected to the outside of one end of the main pipe 101, a first flame retardant layer 103 is fixedly connected to the inside of the main pipe 101, and a second flame retardant layer 104 is fixedly connected to the inside of the first flame retardant layer 103.

[0035] The cooling mechanism 2 includes a sleeve frame 201, and there are two sleeve frames 201 symmetrically arranged. One side of the sleeve frame 201 is fixedly connected with side pieces 208, and there are several side pieces 208 symmetrically arranged. The bottoms of the side pieces 208 are all fixedly connected with sealing rings 209. The main pipes 101 are slidably connected between adjacent sealing rings 209. The other side of the sleeve frame 201 is fixedly connected with adapter pieces 202, and there are several adapter pieces 202 symmetrically arranged. The inner sides of the adapter pieces 202 are all movably connected with first screw rods 203. Nuts 210 are threadedly connected to the outer sides of the bottoms of the first screw rods 203. Pressing rings 204 are fixedly connected to the outer sides of the tops of the first screw rods 203. A fireproof frame 205 is movably connected between the sleeve frame 201 and the main pipe 101, and there are several fireproof frames 205 symmetrically arranged. One side inside the fireproof frame 205 is filled with a coolant. On the other side inside the fireproof frame 205, plugging cavity columns 206 are fixedly connected. The plugging cavity columns 206 are made of glass material, and kerosene is encapsulated in the plugging cavity columns 206. Sealing gaskets are arranged on the sides of the plugging cavity columns 206 close to the fireproof frame 205. The other sides of the fireproof frames 205 are all fixedly connected with bases 207, and there are several bases 207 symmetrically arranged. Second screw rods 211 are threadedly connected to one side inside the sleeve frame 201, and there are several second screw rods 211 symmetrically arranged. A gas guide pipe 212 is fixedly connected to the top of one of the sleeve frames 201, and a branch pipe 213 is fixedly connected to the top of the gas guide pipe 212.

[0036] Specific implementation process: After installing and burying the main pipe 101 at the required position, rotate the first screw rods 203 counterclockwise and loosen them to reduce the pressing force of the bottom of the pressing ring 204 on the outer side of the first screw rod 203 against the adapter piece 202, and release the clamping and fixing of the outer wall of the main pipe 101 between the sealing rings 209 below the sleeve frame 201. Then, slide the device to the required position on the outer side of the main pipe 101, hold the knob 3 and rotate the pressing rings 204 clockwise. By tightening the nuts 210, increase the pressing force of the bottom of the pressing ring 204 against the adapter piece 202, so as to fix the position of the device on the outer wall of the main pipe 101. Rotate the second screw rods 211 inside the sleeve frame 201 to make the bottoms of the second screw rods 211 press the bases 207, and push the fireproof frame 205 below the bases 207 to the position where the fireproof frame 205 fits against the outer wall of the main pipe 101. During the long-term use process, when a fire breaks out outside, the high temperature heats the fireproof frame 205 and the plugging cavity columns 206. Since the kerosene encapsulated in the plugging cavity columns 206 will expand significantly after heating up, the glass plugging cavity columns 206 will burst. At this time, the plugging cavity columns 206 lose the ability to block the fireproof frame 205, and the coolant in the fireproof frame 205 naturally penetrates into the cavity formed between the outer wall of the main pipe 101 and the sleeve frame 201 to moisten and cool the outer wall of the main pipe 101, thereby effectively extending the deformation and damage speed of the pipe body of the main pipe 101 when it is burned by high temperature, and thus leaving a longer time for external personnel to take emergency measures to achieve the purpose of fire prevention.

[0037] Example Two

[0038] Based on Example One:

[0039] The branch pipe 213 is in a spring-like structure. A gas guide pipe 212 is fixedly connected to the bottom of the branch pipe 213, and a sleeve frame 201 is fixedly connected to the bottom of the gas guide pipe 212. This can effectively reduce the dispersion amplitude of the coolant after it seeps out of the fireproof frame 205, ensure the retention time of the coolant, and at the same time discharge the gas when the coolant is heated and evaporated.

[0040] The sealing ring 209 is made of rubber. Side pieces 208 are fixedly connected to one side of the sealing ring 209 respectively, and the sleeve frame 201 is fixedly connected to one side of each side piece 208 respectively. It has relatively excellent heat insulation performance, can effectively reduce the temperature conduction speed, and can also effectively reduce the wear on the outer wall of the main pipe 101.

[0041] Knobs 3 are fixedly connected to one side of the pressure ring 204 respectively. A number of knobs 3 are symmetrically arranged. First screws 203 are fixedly connected to the inner sides of the pressure rings 204 respectively. Nuts 210 are threadedly connected to the outer sides of the bottoms of the first screws 203 respectively. This can effectively facilitate personnel to directly hold and then rotate each of the first screws 203 and the first screws 203.

[0042] Springs 6 are movably connected to the outer sides of the tops of the second screws 211 respectively. The springs 6 are all located on one side of the sleeve frame 201. This can effectively reduce the loosening amplitude generated during the long-term use of the second screws 211.

[0043] Example Three

[0044] Based on Example One:

[0045] Slide bars 7 are fixedly connected to one side of the base 207 respectively. A number of slide bars 7 are symmetrically arranged. The sleeve frame 201 is slidably connected to the outer sides of the slide bars 7 respectively. This can effectively ensure the stability of the position of the base 207.

[0046] Heat insulation layers 5 are fixedly connected to the sides of the sleeve frame 201 close to the fireproof frame 205 respectively. This can further reduce the efficiency of external high-temperature conduction.

[0047] Gaskets 4 are movably connected to the outer sides of the first screws 203 respectively. The gaskets 4 are all located between the adapter pieces 202 and the pressure rings 204. This can effectively reduce the loosening amplitude generated during the long-term use of the nuts 210 and ensure the stability of the position of the first screws 203.

[0048] The sealing rings 209 are all in an arc structure, which can fit more closely to the outer wall of the main pipe 101.

[0049] The main pipe 101 is made of polyphenylene sulfide, which has more excellent flame retardancy and heat resistance and is more stable in a high-temperature environment.
