Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring technology, specifically a leak monitoring device for heating pipelines. Background Technology

[0002] Heating projects are among the most important projects in urban construction. They use pipelines to transport steam or hot water to indoor heating equipment to meet the needs of production and life. However, as the service life of heating pipelines increases, their connection parts are often damaged due to corrosion and other reasons, affecting the normal operation of the pipeline network. Therefore, it is necessary to monitor pipeline faults in real time.

[0003] The existing pipeline leak monitoring devices do not have protective devices installed on the outside, which means that if the device is impacted during the monitoring process, it may be deformed and damaged, affecting the monitoring work. At the same time, most existing monitoring devices only have alarm functions and do not have leak control functions. As a result, after a pipeline leak, the leaked high-temperature gas or liquid may pollute the environment and endanger human health, increasing losses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heating pipeline leakage monitoring device, which has the advantages of good impact resistance and the ability to control leakage, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a heating pipeline leakage monitoring device, including a No. 1 heating pipe and a No. 2 heating pipe, which are connected by a connecting flange. A first monitoring limit mechanism and a second monitoring limit mechanism are snapped and fixed on the surface of the No. 1 heating pipe and the No. 2 heating pipe. A first protection mechanism and a second protection mechanism are snapped and fixed on the surface of the first monitoring limit mechanism and the second monitoring limit mechanism. A plurality of fixing bolts are threadedly connected between the No. 1 protection mechanism and the No. 2 protection mechanism, and a fixing nut is threadedly sleeved on the lower end face of each of the plurality of fixing bolts.

[0006] As a preferred technical solution of this utility model, the upper end face of the first monitoring and limiting mechanism is engaged with two engaging blocks, the upper end face of the two engaging blocks is fixedly installed with a mechanism shell, and the upper end face of the mechanism shell is fixedly installed with a transparent plate.

[0007] As a preferred technical solution of this utility model, the first monitoring and limiting mechanism includes a first monitoring and limiting block. Multiple warning lights and alarms are fixedly installed on the upper surface of the first monitoring and limiting block. Two snap-fit ​​holes are opened on the upper surface of the first monitoring and limiting block. Multiple positioning holes are opened on the lower surface of the first monitoring and limiting block. Magnetic blocks are fixedly installed on the inner walls of the multiple positioning holes. A first sealing gasket is fixedly installed on the inner wall of the first monitoring and limiting block. A monitor is fixedly installed on the inner wall of the first monitoring and limiting block.

[0008] As a preferred embodiment of the present invention, the second monitoring and limiting mechanism includes a second monitoring and limiting block, a plurality of positioning rods are fixedly installed on the upper end face of the second monitoring and limiting block, and a second sealing gasket is fixedly installed on the inner wall of the second monitoring and limiting block.

[0009] As a preferred technical solution of this utility model, the first protective mechanism includes a first protective shell, a first elastic block is fixedly installed on the upper surface of the first protective shell, a second transparent plate is fixedly installed on the upper surface of the first protective shell, and two first impact-resistant layers are fixedly installed on the upper surface of the first protective shell.

[0010] As a preferred technical solution of this utility model, the second protection mechanism includes a second protective shell, and a second elastic block and a second impact-resistant layer are fixedly installed on the upper surface of the second protective shell.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This heating pipeline leakage monitoring device uses fixing bolts and nuts to install and fix the No. 1 and No. 2 protection mechanisms on the outside of the monitoring device. The elastic block is made of corrosion-resistant rubber, which has good elasticity and corrosion resistance. The impact-resistant layer is made of foamed aluminum, which has good impact resistance and can absorb the impact force when the protection mechanism is hit, so as to avoid the monitoring device being directly damaged by impact and affecting the pipeline leakage monitoring work.

[0012] 2. This heating pipeline leakage monitoring device is fixed by a positioning rod and positioning hole. After being further pressed and fixed by the first and second protection mechanisms, the first and second sealing gaskets will form a sealed space at the pipeline connection. The sealing gaskets are made of high-temperature resistant rubber to prevent the leaked high-temperature gas or liquid from melting the sealing gaskets. When there is a leak at the pipeline connection, the monitor will issue an alarm through the alarm light and alarm. At the same time, the first and second sealing gaskets will prevent the leaked high-temperature gas or liquid from spreading and polluting the environment and endangering people. This can greatly reduce leakage losses. Attached Figure Description

In the above structure, the first monitoring limit mechanism 3 and the second monitoring limit mechanism 4 are installed and fixed at the connecting flange 12 of the first heating pipe 1 and the second heating pipe 2 by interlocking. This is used to monitor the leakage at the connection. At the same time, the first protection mechanism 5 and the second protection mechanism 6 are installed and fixed on the outside of the monitoring device by fixing bolts 7 and fixing nuts 8 to protect the monitoring device and prevent it from being damaged by impact, which would affect the monitoring.

[0017] In a preferred embodiment, the first monitoring and limiting mechanism 3 includes a first monitoring and limiting block 301. Multiple warning lights 304 and an alarm 303 are fixedly installed on the upper surface of the first monitoring and limiting block 301. Two snap-fit ​​holes 305 are opened on the upper surface of the first monitoring and limiting block 301. Multiple positioning holes 307 are opened on the lower surface of the first monitoring and limiting block 301. Magnetic blocks 306 are fixedly installed on the inner walls of the multiple positioning holes 307. A first sealing gasket 302 is fixedly installed on the inner wall of the first monitoring and limiting block 301. A monitor 308 is fixedly installed on the inner wall of the first monitoring and limiting block 301. The second monitoring and limiting mechanism 4 includes a second monitoring and limiting block 401. Multiple positioning rods 402 are fixedly installed on the upper surface of the second monitoring and limiting block 401. A second sealing gasket 403 is fixedly installed on the inner wall of the second monitoring and limiting block 401. In the above structure, the positioning rod 402 and the positioning hole 307 are interlocked, and the positioning rod 402 is attracted by the magnetic block 306, thereby fixing the first monitoring limit mechanism 3 and the second monitoring limit mechanism 4 to the surface of the heating pipe. The monitor 308 inside the first monitoring limit mechanism 3 will monitor whether the heating pipe is leaking in real time. Multiple warning lights 304 and alarms 303 installed on the upper end of the first monitoring limit block 301 can flash different colored warning lights 304 and different high and low alarm sounds according to the leakage speed to promptly remind the staff. The first sealing gasket 302 and the second sealing gasket 403 will form a sealed space at the pipe connection, so that when the pipe leaks, the high temperature gas or liquid will not spray everywhere, avoiding environmental pollution or harm to people.

[0018] In a preferred embodiment, the first protective mechanism 5 includes a first protective shell 501, a first elastic block 502 is fixedly installed on the upper end surface of the first protective shell 501, a second transparent plate 503 is fixedly installed on the upper end surface of the first protective shell 501, and two first impact-resistant layers 504 are fixedly installed on the upper end surface of the first protective shell 501.

[0019] The working principle is as follows: the positioning rod 402 and the positioning hole 307 are interlocked, and the positioning rod 402 is attracted by the magnetic block 306, thus fixing the first monitoring limit mechanism 3 and the second monitoring limit mechanism 4 to the surface of the heating pipe. The monitor 308 inside the first monitoring limit mechanism 3 will monitor whether the heating pipe is leaking in real time. Multiple warning lights 304 and alarms 303 installed on the upper end of the first monitoring limit block 301 can flash different colors of warning lights 304 and generate different levels of alarm sounds according to the leakage speed, so as to promptly remind the staff. The first sealing gasket 302 and the second sealing gasket 403 will form a sealed space at the pipe connection, so that when the pipe leaks, the high temperature gas or liquid will not spray everywhere, avoiding environmental pollution or harm to people. To reduce pipeline leakage losses, the sealing gasket is made of high-temperature resistant rubber, which can prevent the leaked high-temperature gas or liquid from melting the sealing gasket. The mechanism housing 9 and the first transparent plate 10 are snapped and fixed to the upper end of the first monitoring limit mechanism 3 by the snap-fit ​​block 11 to protect the warning light 304 and the alarm 303.
