The pipe body 1 is covered with a rock wool layer 2, and the pipe body 1 is provided with an electric heating film 8 , and the pipe body 1 is provided with a sharp barb 3 , and the sharp barb 3 penetrates the rock wool layer 2 Exposed to the surface of the rock wool layer 2, the pipe body 1 is provided with matching threads at both ends, a middle portion of the pipe body 1 is provided with a clamp-shaped buckle 5, and the rock wool layer 2 is coated with a fluorescent layer, the pipe body 1 It is set as a double layer, and air is filled between the inner and outer layers. The sharp barb 3 is 2 cm higher than the rock wool layer, and the pipe body 1 is provided with a screen 6 which is a curved metal needle.
所述管道主体 1内设电热膜 8，主要解决冬天管道内结冰堵塞管道影响使用的问题。所述电热膜 8内设于管道里面，沿其内径均匀的包覆一层，当管道内结冰时，不仅影响下水管道继续使用，持续结冰的状况还会造成管道损坏，使用者接通电热膜 8的电源，电热膜 8温度升高，与其接触的冰融化为水，顺着管道流下。电热膜 8设置延长导线，延长导线埋设于墙内通向室内，室内安装电源插座。这样，业主在室内就可以完成除冰作业，不必跑到室外。所述管道主体 1设置为蜂窝状结构 9， 蜂窝状结构密度很小，自身轻，凹凸不平绝缘效果好，该结构 使反射的回声能量降低，减弱声音的反射，减小回声，对噪音的吸收力强，可以起到很好的降噪作用 。The electric heating film 8 is arranged in the main pipe body 1 to solve the problem of the influence of the blocked pipe in the winter pipe. The electric heating film 8 is built in the pipe and covered with a uniform layer along the inner diameter. When the pipe is frozen, it not only affects the continued use of the sewer pipe, but also causes the pipe to be damaged due to the continuous icing condition. The user turns on the electric heating film 8 Power supply, electric heating film 8 The temperature rises and the ice in contact with it melts into water and flows down the pipe. Electric film 8 Set the extension wire, the extension wire is buried in the wall and leads to the room, and the power socket is installed indoors. In this way, the owner can complete the de-icing operation indoors without having to go outside. The pipe body 1 is arranged in a honeycomb structure 9 The honeycomb structure has a small density, is light in itself, and has a good insulating effect. The structure reduces the echo energy of the reflection, reduces the reflection of the sound, reduces the echo, and has a strong absorption of noise, which can achieve a good noise reduction effect. .
所述管道主体 1 设置尖锐倒刺 3 ，让盗贼无处着手，即使在黑夜中盗贼没有察觉倒刺的存在，当他用手或身体接触下水管道时，尖锐倒刺 3 也会刺痛盗贼，让其知难而退。所述管道主体 1 外包覆岩棉层 2 ，保护内部主体管道，水流从中经过时岩棉可以稀释其噪音，室外管道如果直接裸露于太阳光和空气中老化很快，包覆岩棉可以延缓管道老化，提高其使用寿命。为了拆卸安装方便，所述管道主体 1 两端设置适配的螺纹，管道主体 1 分段设计，首尾相接通过螺纹装配在一起，根据楼房高度选取合适的管道节数。所述管道主体 1 中段设置卡箍形锁扣 5 ，外墙打入钢钉或膨胀螺丝等固定设施，卡箍形锁扣 5 一端套接卡箍在管道主体 1 上，一端穿过膨胀螺丝卡合扣紧。 The pipe body 1 is provided with a sharp barb 3 Let the thieves have nowhere to start, even if the thieves do not notice the existence of barbs in the dark, when he touches the sewer pipe by hand or body, the sharp barbs 3 will also sting the thieves and let them know. The pipe body 1 is covered with a rock wool layer 2 The internal main pipe is protected. When the water flows through it, the rock wool can dilute its noise. If the outdoor pipe is exposed to sunlight and air, the aging of the outdoor pipe is very fast. The coated rock wool can delay the aging of the pipe and improve its service life. The pipe body is convenient for disassembly and installation 1 Set the matching threads at both ends. The main body of the pipe is designed in sections. The first and last ends are assembled by threads, and the appropriate number of pipe joints is selected according to the height of the building. a clamp-shaped lock buckle is arranged in the middle of the pipe main body 1 The outer wall is driven into a fixing device such as a steel nail or an expansion screw, and the clamp-shaped lock buckle 5 has a socket clamped on the pipe main body 1 at one end, and one end is fastened by the expansion screw.
所述岩棉层 2 涂抹荧光层，夜晚可以反射光芒，明亮的物体会对盗贼心理上产生影响，使其放弃攀爬下水管道的企图；没有月亮的夜晚，人们用手电筒照射下水管道时，荧光层使得目标格外明显，便于及时发现是否有人攀爬下水管道。 The rock wool layer 2 Applying a fluorescent layer, the night can reflect light, bright objects will have an impact on the thieves' psychological impact, making it abandon the attempt to climb the sewer pipe; when there is no moon night, when the flashlight is used to illuminate the sewer pipe, the fluorescent layer makes the target exceptionally obvious. It is convenient to find out in time whether someone is climbing the sewer.
所述管道主体 1 设置为双层，内外层之间填充空气，可以有效降低下水时产生的噪音，同时便于安装，操作者可以抓住内管 4 ，进行固定管道、螺丝连接等工作。 The pipe body 1 It is set as a double layer, and the air is filled between the inner and outer layers, which can effectively reduce the noise generated when the water is launched, and is easy to install. The operator can grasp the inner tube 4 and perform fixed pipe and screw connection.
所述管道主体 1 设置滤网 6 ，滤网 6 设置在管口，可以有效阻挡树枝等杂物进入管道造成堵塞，同时因为设置了滤网 6 ，下水管道不必设计的过粗，较细的下水管也可以完全胜任。 The pipe body 1 is provided with a filter screen 6 and a filter screen 6 Set at the nozzle, it can effectively block the debris from entering the pipeline and cause blockage. At the same time, because the filter 6 is installed, the sewage pipe does not have to be designed too thick, and the thin water pipe can be fully qualified.
所述尖锐倒刺 3 为弯曲金属针状物，尖锐锋利，像刺猬的盔甲一样让人望而生畏。 The sharp barbs 3 are curved metal needles that are sharp and sharp, and are as daunting as a hedgehog armor.
发明人通过大量试验，优选了尖锐倒刺 3 高出岩棉层 2cm 。 The inventors passed a large number of tests, preferably sharp barbs 3 2 cm above the rock wool layer.
