Description

Technical Field

[0001] The utility model belongs to the technical field of power pipe monitoring, in particular to a damage-triggered early warning power pipe. Background Art

[0002] PVC power pipe refers to a rigid polyvinyl chloride pipe of various specifications made of PVC resin as the main raw material and various stabilizers added. It has strong corrosion resistance, is not affected by corrosive soil, has a smooth inner wall, has less friction resistance than other materials, is easy to construct, and has a wide range of uses.

[0003] At present, a large number of PVC power pipes are laid underground. After long-term use, the power pipes are easily damaged due to corrosion and other influences. Due to the lack of damage warning devices for power pipes, they are not detected until the damage inside the pipeline is serious, resulting in great losses each time. In order to solve the above problems, a damage-triggered warning power pipe is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a damage-triggered early warning power tube in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is as follows: a damage triggered warning electric pipe, comprising an electric pipe body formed integrally of an inner pipe layer and an outer pipe layer, a gas layer is filled between the inner pipe layer and the outer pipe layer, a trigger component is installed on one side of the outer pipe layer, the trigger component comprises a three-way pipe with one end connected to the gas layer, and the other two ends of the three-way pipe are respectively threadedly installed with a one-way valve and an air pressure sensor.

[0006] In a preferred embodiment, the gas filled in the gas layer is nitrogen.

[0007] In a preferred embodiment, the one-way valve is oriented from outside to inside, and a sealing ring is provided in an interference fit at the connection between the one-way valve and the air pressure sensor and the three-way pipe.

[0008] In a preferred embodiment, a mounting seat is integrally provided at the outer end of the three-way pipe, and a protective cover for covering the three-way pipe is detachably mounted on the mounting seat.

[0009] In a preferred embodiment, a transmission line of an external power supply and a control terminal is provided at one end of the air pressure sensor, and a threading hole for extending the transmission line is provided on the side wall of the protective cover.

[0010] In a preferred embodiment, the protective cover is made of stainless steel.

[0011] To sum up, due to the adoption of the above-mentioned technical scheme, the beneficial effect of the utility model is: a damage automatic trigger warning part is designed on the power pipe. When the outer pipe layer is damaged, the gas inside the gas layer will escape. At this time, the data received by the air pressure sensor set will undergo a large change, and then the changed data will be transmitted to the control terminal. The control terminal will remind the power pipeline of damage, so that it can be known whether the pipeline is damaged in the early stage of damage, thereby reducing the loss caused by the damage.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] Reference Figure 1-2 A damage-triggered warning electric pipe comprises an electric pipe body integrally formed by an inner pipe layer 2 and an outer pipe layer 1, a gas layer 3 is filled between the inner pipe layer 2 and the outer pipe layer 1, a trigger component 6 is installed on one side of the outer pipe layer 1, the trigger component 6 comprises a three-way pipe 602 connected to the gas layer 3 at one end, and a one-way valve 601 and an air pressure sensor 604 are respectively threadedly installed at the other two ends of the three-way pipe 602, a gas layer 3 and a trigger component 6 connected to the gas layer 3 are designed on the electric pipe, when the outer pipe layer 1 is damaged, the gas inside the gas layer 2 will overflow, and the data received by the air pressure sensor 604 set at this time will change significantly, and then the changed data will be transmitted to the control terminal, and the control terminal will remind the staff that the electric pipeline is damaged and maintenance operations are required, so that it can be known whether the pipeline is damaged in the early stage of damage, thereby reducing the loss caused by the damage.

[0017] It should be mentioned here that the outer layer of the current power pipe is mainly a corrosion-resistant and wear-resistant layer, and the inner layer is an insulating layer. When the outer layer is damaged, the inner layer will also be basically affected. Therefore, an early warning can be triggered when the outer layer is damaged.

[0018] Furthermore, the gas filled in the gas layer 3 is nitrogen, which is an inert gas, extremely inactive, and has a certain non-combustible property, and can play a certain protective and fire-preventing role in the event of a fire.

[0019] Reference Figure 2 As shown, the direction of the one-way valve 601 is from outside to inside, and the one-way valve 601, the air pressure sensor 604 and the three-way pipe 602 are interference-fitted with a sealing ring 603. The sealing ring 603 can improve the sealing of the connection between the one-way valve 601, the air pressure sensor 604 and the three-way pipe 602 to avoid leakage, and the one-way valve 601 and the air pressure sensor 604 are also detachable, which can meet the replacement and maintenance operations of the one-way valve 601 and the air pressure sensor 604.

[0020] Furthermore, a mounting seat 5 is integrally provided at the outer end of the three-way pipe 602 , and a protective cover 4 for covering the three-way pipe 602 is detachably mounted on the mounting seat 5 . The protective cover 4 is made of stainless steel material, and the internal trigger assembly 6 is protected by the designed mounting seat 5 .

[0021] The mounting base 5 and the protective cover 4 are fixed by threads (the air pressure sensor 604 is installed at the upper end of the three-way pipe 602) or bolts to facilitate the subsequent maintenance and replacement of internal components.

[0022] Furthermore, one end of the air pressure sensor 604 is provided with a transmission line 605 for an external power supply and a control terminal, and the side wall of the protective cover 4 is provided with a threading hole for the transmission line 605 to extend out, wherein the control terminal is preferably a mobile phone or a computer. When the data monitored by the air pressure sensor 604 changes greatly, it means that an internal leakage occurs.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
