Description

Technical Field

[0001] The present invention relates to the technical field of displacement detection, and more specifically to a pipeline displacement monitoring alarm system and a pipeline displacement monitoring device. Background Art

[0002] In some application scenarios, pipelines have a great impact on on-site equipment and applications. For example, during the use of pipelines, a certain displacement will occur due to various factors. However, when the displacement of the pipeline is too much, it may damage the pipeline, causing sudden accidents such as pipeline breakage and leakage. In the prior art, the inspection of pipeline status is usually carried out by on-site staff. However, it is very likely that the pipeline displacement exceeding the limit will not be discovered in time, especially for application scenarios with a large number of on-site pipelines and a wide range. At this time, only by inspecting the pipelines in sequence by staff, the efficiency is not only low, but it is also likely that the pipeline exceeding the limit cannot be discovered in time and quickly, resulting in the expansion of the accident.

[0039] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0040] like Figure 1 As shown, in an embodiment of the pipeline displacement monitoring and alarm system of the present invention, the system includes a magnetically controlled displacement monitoring device, a signal transmitting unit and a signal receiving unit;

[0041] The magnetically controlled displacement monitoring device monitors the displacement of the pipeline to be tested and generates a displacement signal when the displacement reaches the displacement limit value;

[0042] The signal transmitting unit is electrically connected to the magnetically controlled displacement monitoring device, receives the displacement signal and triggers the sending of a monitoring signal corresponding to the pipeline to be tested; the signal receiving unit is communicatively connected to the signal transmitting unit, receives the monitoring signal and processes the monitoring signal to obtain the position information of the pipeline to be tested, and generates an alarm signal.

[0043] It should be noted that the displacement limit value is preset and determined according to the application type of the pipeline to be tested. It is understandable that in actual applications, facing different application scenarios, the displacement limit value and the direction of the displacement limit generated by the pipeline to be tested are different, and the displacement limit value can be preset according to actual needs.

[0044] In some embodiments, the magnetically controlled displacement monitoring device includes: a magnetically controlled monitoring ring 30 and a magnet 2; the first end of the magnet 2 is arranged at the central axis position of the magnetically controlled monitoring ring 30, and the second end is fixedly connected to the pipeline 1 to be measured through a mounting bracket 4; when the pipeline 1 to be measured is displaced, the magnet 2 is driven to generate a corresponding displacement; the magnetically controlled monitoring ring 30 monitors the displacement generated by the pipeline 1 to be measured, and when the displacement reaches the displacement limit value, the magnet 2 triggers the magnetically controlled monitoring ring 30 to generate a displacement signal.

[0045] Specifically, Figure 2 , Figure 3 , Figure 4 As shown, the magnetic control monitoring ring 30 is installed at a certain distance from the pipeline 1 to be tested through the mounting bracket 4, the first end of the magnet 2 is set at the central axis position of the magnetic control monitoring ring 30, and the second end is fixedly connected to the pipeline 1 to be tested through the mounting bracket 4. When the pipeline 1 to be tested is displaced in the horizontal or vertical direction, the magnet 2 is driven to produce a corresponding displacement, so that the magnetic control monitoring ring 30 can monitor.

[0046] Since the pipeline 1 to be tested is fixedly connected to the second end of the magnet 2, the first end of the magnet 2 is set at the central axis position of the magnetically controlled monitoring ring 30 through the mounting bracket but is not fixed at the central axis position, so that when the second end of the magnet 2 is driven to displace by the pipeline 1 to be tested, the magnet 2 generates a displacement in the same direction as the displacement of the pipeline 1 to be tested. Before the displacement, the magnet 2 is located at the central axis position of the magnetically controlled monitoring ring 30, so that each position on the magnetically controlled monitoring ring 30 is evenly distributed in the magnetic field; and when the displacement occurs, the position of the magnet 2 changes, so that the magnetic force on the part of the magnetically controlled monitoring ring 30 closer to the magnet 2 gradually increases, until the displacement generated by the magnet 2 reaches the displacement over-limit value, and the magnetic force increases to be sufficient to trigger the magnetically controlled monitoring ring 30 to send a displacement signal. The technical effect of being able to monitor whether the displacement of the pipeline 1 to be tested exceeds the limit is achieved.

[0047] Optionally, according to actual application conditions, the magnetically controlled monitoring ring 30 can be installed in the horizontal direction at a set distance from the pipeline 1 to be tested, and the center axis position can be set in the vertical direction, so as to achieve the technical effect of monitoring the displacement of the pipeline 1 to be tested in the horizontal direction and promptly issuing a displacement signal when the horizontal displacement reaches the displacement limit value.

[0048] Optionally, according to actual application conditions, the magnetically controlled monitoring ring 30 can be installed in the vertical direction at a set distance from the pipeline 1 to be tested, and the center axis position can be set in the horizontal direction, so as to achieve the technical effect of monitoring the displacement of the pipeline 1 to be tested in the vertical direction and promptly issuing a displacement signal when the vertical displacement reaches the displacement limit value.

[0049] Optionally, the magnetically controlled monitoring ring 30 includes a plurality of normally closed reed switches connected in series; when the displacement reaches an over-limit value, the normally closed reed switches are disconnected by the magnet 2 and the magnetically controlled monitoring ring 30 generates a displacement signal.

[0050] Optionally, the magnetically controlled monitoring ring 30 includes a plurality of normally open reed switches connected in parallel; when the displacement reaches an over-limit value, the magnet 2 triggers the normally open reed switches to close and the magnetically controlled monitoring ring 30 generates a displacement signal.

[0051] Specifically, the magnetically controlled monitoring ring 30 includes a reed switch electrically connected to the signal transmitting unit; the reed switch includes a normally open reed switch and a normally closed reed switch. In practical applications, the normally open reed switch or the normally closed reed switch can be selected according to needs. When the displacement of the pipeline 1 to be tested reaches the displacement exceeding limit value, the magnet 2 triggers the normally closed reed switch to disconnect, and the magnetically controlled monitoring ring 30 generates a displacement signal, so as to promptly reflect that the displacement of the pipeline 1 to be tested exceeds the limit.

[0052] The magnetically controlled monitoring ring 30 is formed by connecting a plurality of normally open reed switches in parallel. When the displacement of the pipeline 1 to be tested reaches the displacement exceeding limit value, the magnet 2 triggers the normally open reed switches to close, and the magnetically controlled monitoring ring 30 generates a displacement signal, so as to promptly reflect that the displacement of the pipeline 1 to be tested exceeds the limit. The number of reed switches is determined according to the application type of the pipeline 1 to be tested in the actual application scenario.

[0053] It should be noted that the reed switch includes the normally closed reed switch and the normally open reed switch. The specific structure and working principle of the reed switch can refer to the prior art. The working principle of the normally closed reed switch is as follows: there are two reeds with contacts attracted inside the normally closed reed switch; when a permanent magnet approaches the reed switch, the contacts of the two reeds will induce magnetic poles with the same polarity. When the magnetic force exceeds the magnetic force of the reed, the attracted contacts will separate; when the magnetic force decreases to a certain value, the contacts return to the initial state. In this way, the function of a switch is completed.

[0054] The working principle of the normally open reed switch is as follows: there are two reeds with separate contacts in the normally open reed switch; when a permanent magnet approaches the reed switch, the contacts of the two reeds will induce magnetic poles of opposite polarity and attract each other. When the magnetic force exceeds the resistance of the reed, the separated contacts will be attracted; when the magnetic force decreases to a certain value, the contacts return to the initial state to complete the function of a switch. It can be understood that the structural components and structural relationships of the reed switch can also refer to the prior art.

[0055] In a preferred embodiment, Figure 2 , Figure 3 , Figure 4 As shown; the magnetically controlled monitoring ring 30 includes a first magnetically controlled monitoring ring 301 for monitoring the horizontal displacement of the pipeline 1 to be tested, and a second magnetically controlled monitoring ring 302 for monitoring the vertical displacement of the pipeline 1 to be tested; the magnet 2 includes a first magnet 21 and a second magnet 22;

[0056] The central axis position of the first magnetically controlled monitoring ring 301 is set in a vertical direction with a set distance from the pipeline 1 to be tested; the first end of the first magnet 21 is set at the central axis position of the first magnetically controlled monitoring ring 301, and the second end is fixedly connected to the pipeline 1 to be tested;

[0057] The central axis displacement of the second magnetically controlled monitoring ring 302 is set in the horizontal direction at a set distance from the pipeline to be measured 1; the first end of the second magnet 22 is set at the central axis position of the second magnetically controlled monitoring ring 302, and the second end is fixedly connected to the pipeline to be measured 1; and the second end of the second magnet 22 is fixedly connected to the second end of the first magnet 21.

[0058] Specifically, Figure 2 As shown, in actual application scenarios, the displacement of the pipeline may be in the horizontal direction, in the vertical direction, or in both the horizontal and vertical directions. In order to more accurately monitor the displacement of the pipeline 1 to be tested and whether it reaches the over-limit value, a magnetically controlled monitoring ring 30 is set in the horizontal direction and the vertical direction respectively, so that no matter the displacement of the pipeline in the horizontal or vertical direction exceeds the displacement limit value, it can be monitored. Especially at the turning point of the pipeline, it is necessary to monitor the horizontal and vertical directions at the same time, so the first magnetically controlled monitoring ring 301 and the second magnetically controlled monitoring ring 302 are installed at the same time to achieve the technical effect of improving the accuracy of monitoring the over-limit displacement at the turning point of the pipeline.

[0059] refer to Figure 2 , Figure 3 as well as Figure 4, the first magnetically controlled monitoring ring 301 is arranged in the horizontal direction with a set distance from the pipeline 1 to be tested, and the central axis position is arranged in the vertical direction with a set distance from the pipeline 1 to be tested; so as to realize the displacement monitoring of the pipeline 1 to be tested in the horizontal direction. The first end of the first magnet 21 is arranged at the central axis position of the first magnetically controlled monitoring ring 301, and the second end is fixedly connected to the pipeline 1 to be tested. The first magnet 21 generates corresponding displacement with the displacement of the pipeline 1 to be tested; so that when the displacement of the pipeline 1 to be tested in the horizontal direction reaches the displacement limit value, the first magnet 21 can timely trigger the first magnetically controlled monitoring ring 301 to generate a displacement signal, so as to achieve the technical effect of timely knowing that the displacement of the pipeline 1 to be tested has reached the displacement limit value, and a pipeline accident may occur and the staff needs to deal with it in time.

[0060] On this basis, the second magnetically controlled monitoring ring 302 is arranged in a vertical direction at a set distance from the pipeline 1 to be tested, and the central axis position is arranged in a horizontal direction at a set distance from the pipeline 1 to be tested, so as to realize the displacement monitoring of the pipeline 1 to be tested in the vertical direction. The first end of the second magnet 22 is arranged at the central axis position of the second magnetically controlled monitoring ring 302, and the second end is fixedly connected to the pipeline 1 to be tested, and the second end of the second magnet 22 is fixedly connected to the second end of the first magnet 21.

[0061] The first magnet 21 and the second magnet 22 simultaneously generate corresponding displacements with the displacement of the pipeline 1 to be tested; so that when the displacement of the pipeline 1 to be tested in the vertical direction reaches the displacement limit value, the second magnet 22 can timely trigger the second magnetically controlled monitoring ring 302 to generate a displacement signal, so as to achieve the technical effect of timely knowing that the displacement of the pipeline 1 to be tested has reached the displacement limit value, and a pipeline accident may occur and the staff needs to handle it in time. Since the second end of the first magnet 21 is fixedly connected to the second end of the second magnet 22 and is fixedly connected to the pipeline 1 to be tested through the mounting bracket 4, the displacement of the pipeline in the horizontal or vertical direction exceeding the displacement limit value can be monitored.

[0062] In some embodiments, the signal transmitting unit is electrically connected to the magnetically controlled monitoring ring 30, receives the displacement signal and triggers the sending of the monitoring signal corresponding to the pipeline 1 to be tested; the signal receiving unit receives the monitoring signal and processes the monitoring signal to obtain the position information of the pipeline 1 to be tested, and generates an alarm signal. When the magnetically controlled monitoring ring 30 detects that the displacement of the pipeline 1 to be tested in the horizontal or vertical direction reaches the displacement limit value, the signal transmitting unit and the signal receiving unit communicate, so that the staff can know the displacement of the pipeline 1 to be tested in time and obtain the position information of the pipeline 1 to be tested, so as to quickly deal with the pipeline with the risk of accidents.

[0063] Specifically, the signal transmitting unit includes a first switch quantity coding transmitter; the signal receiving unit includes a first switch quantity coding receiver; the first switch quantity coding transmitter is connected to the first switch quantity coding receiver in communication; the first switch quantity coding transmitter triggers and starts after receiving the displacement signal, and transmits the monitoring signal; the first switch quantity coding receiver receives the monitoring signal, and demodulates the monitoring signal to obtain the coding address, so as to obtain the position information of the pipeline to be tested 1. This allows the staff to know the displacement of the pipeline to be tested 1 in a timely manner and also obtain the position information of the pipeline to be tested 1, so as to quickly handle the pipeline with the risk of accidents.

[0064] In some embodiments, the pipeline displacement monitoring and alarm system further includes a display alarm unit communicatively connected to the signal receiving unit; the display alarm unit acquires and displays position information, receives an alarm signal and emits an audible and visual alarm to remind the pipeline 1 to be tested that displacement exceeds the limit.

[0065] In an embodiment of the pipeline displacement monitoring device of the present invention, the pipeline displacement monitoring device comprises: a magnetically controlled monitoring ring 30 and a magnet 2;

[0066] The first end of the magnet 2 is arranged at the central axis position of the magnetically controlled monitoring ring 30, and the second end is fixedly connected to the pipeline 1 to be tested through a mounting bracket; when the pipeline 1 to be tested is displaced, the magnet 2 is driven to produce a corresponding displacement; the magnetically controlled monitoring ring 30 monitors the displacement amount of the pipeline 1 to be tested, and when the displacement amount reaches the displacement limit value, the magnet 2 triggers the magnetically controlled monitoring ring 30 to generate a displacement signal.

[0067] Specifically, the magnetic control monitoring ring 30 is installed at a certain distance from the pipeline 1 to be tested through a mounting bracket, the first end of the magnet 2 is set at the central axis position of the magnetic control monitoring ring 30, and the second end is fixedly connected to the pipeline 1 to be tested through the mounting bracket. When the pipeline 1 to be tested is displaced in the horizontal or vertical direction, the magnet 2 is driven to produce a corresponding displacement, so that the magnetic control monitoring ring 30 can monitor.

[0068] Since the pipeline 1 to be tested is fixedly connected to the second end of the magnet 2, the first end of the magnet 2 is set at the central axis position of the magnetically controlled monitoring ring 30 through the mounting bracket but is not fixed at the central axis position, so that when the second end of the magnet 2 is driven to displace by the pipeline 1 to be tested, the magnet 2 generates a displacement in the same direction as the displacement of the pipeline 1 to be tested. Before the displacement, the magnet 2 is located at the central axis position of the magnetically controlled monitoring ring 30, so that each position on the magnetically controlled monitoring ring 30 is evenly distributed in the magnetic field; and when the displacement occurs, the position of the magnet 2 changes, so that the magnetic force on the part of the magnetically controlled monitoring ring 30 closer to the magnet 2 gradually increases, until the displacement generated by the magnet 2 reaches the displacement over-limit value, and the magnetic force increases to be sufficient to trigger the magnetically controlled monitoring ring 30 to send a displacement signal. The technical effect of being able to monitor whether the displacement of the pipeline 1 to be tested exceeds the limit is achieved.

[0069] Optionally, according to actual application conditions, the magnetically controlled monitoring ring 30 can be installed in the horizontal direction at a set distance from the pipeline 1 to be tested, and the center axis position can be set in the vertical direction, so as to achieve the technical effect of monitoring the displacement of the pipeline 1 to be tested in the horizontal direction and promptly issuing a displacement signal when the horizontal displacement reaches the displacement limit value.

[0070] Optionally, according to actual application conditions, the magnetically controlled monitoring ring 30 can be installed in the vertical direction at a set distance from the pipeline 1 to be tested, and the center axis position can be set in the horizontal direction, so as to achieve the technical effect of monitoring the displacement of the pipeline 1 to be tested in the vertical direction and promptly issuing a displacement signal when the vertical displacement reaches the displacement limit value.

[0071] Optionally, the magnetically controlled monitoring ring 30 includes a plurality of normally closed reed switches connected in series; when the displacement reaches an over-limit value, the normally closed reed switches are disconnected by the magnet 2 and the magnetically controlled monitoring ring 30 generates a displacement signal.

[0072] Optionally, the magnetically controlled monitoring ring 30 includes a plurality of normally open reed switches connected in parallel; when the displacement reaches an over-limit value, the magnet 2 triggers the normally open reed switches to close and the magnetically controlled monitoring ring 30 generates a displacement signal.

[0073] Specifically, the magnetically controlled monitoring ring 30 includes a reed switch; the reed switch includes a normally open reed switch and a normally closed reed switch. In practical applications, the normally open reed switch or the normally closed reed switch can be selected according to needs. The magnetically controlled monitoring ring 30 composed of a plurality of normally closed reed switches connected in series, when the displacement of the pipeline 1 to be tested reaches the displacement exceeding limit value, the magnet 2 triggers the normally closed reed switch to disconnect, and the magnetically controlled monitoring ring 30 generates a displacement signal, so as to promptly reflect that the displacement of the pipeline 1 to be tested exceeds the limit.

[0074] The magnetically controlled monitoring ring 30 is formed by connecting several normally open reed switches in parallel. When the displacement of the pipeline 1 to be tested reaches the displacement exceeding limit value, the magnet 2 triggers the normally open reed switches to close and the magnetically controlled monitoring ring 30 to generate a displacement signal, so as to promptly reflect that the displacement of the pipeline 1 to be tested exceeds the limit. The number of reed switches is determined according to the application type of the pipeline 1 to be tested in the actual application scenario. In other words, the diameter of the magnetically controlled monitoring ring 30 formed by connecting several reed switches is determined according to the application type of the pipeline 1 to be tested in the actual application scenario.

[0075] It should be noted that the reed switch includes the normally closed reed switch and the normally open reed switch. The specific structure and working principle of the reed switch can refer to the prior art. The working principle of the normally closed reed switch is as follows: there are two reeds with contacts attracted inside the normally closed reed switch; when a permanent magnet approaches the reed switch, the contacts of the two reeds will induce magnetic poles with the same polarity. When the magnetic force exceeds the magnetic force of the reed, the attracted contacts will separate; when the magnetic force decreases to a certain value, the contacts return to the initial state. In this way, the function of a switch is completed.

[0076] The working principle of the normally open reed switch is as follows: there are two reeds with separate contacts in the normally open reed switch; when a permanent magnet approaches the reed switch, the contacts of the two reeds will induce magnetic poles of opposite polarity and attract each other. When the magnetic force exceeds the resistance of the reed, the separated contacts will be attracted; when the magnetic force decreases to a certain value, the contacts return to the initial state to complete the function of a switch. It can be understood that the structural components and structural relationships of the reed switch can also refer to the prior art.

[0077] In a preferred embodiment, the magnetically controlled monitoring ring 30 includes a first magnetically controlled monitoring ring 301 for monitoring the horizontal displacement of the pipeline 1 to be tested, and a second magnetically controlled monitoring ring 302 for monitoring the vertical displacement of the pipeline 1 to be tested; the magnet 2 includes a first magnet 21 and a second magnet 22;

[0078] The central axis position of the first magnetically controlled monitoring ring 301 is set in a vertical direction with a set distance from the pipeline 1 to be tested; the first end of the first magnet 21 is set at the central axis position of the first magnetically controlled monitoring ring 301, and the second end is fixedly connected to the pipeline 1 to be tested;

[0080] Specifically, Figure 2 As shown, Figure 2 A schematic diagram of the installation of the magnetically controlled monitoring ring 30 provided by the present invention;

[0081] In actual application scenarios, the displacement of the pipeline may be in the horizontal direction, in the vertical direction, or in both the horizontal and vertical directions. In order to more accurately monitor the displacement of the pipeline 1 to be tested and whether it reaches the limit value, a magnetically controlled monitoring ring 30 is set in the horizontal direction and the vertical direction respectively, so that the displacement of the pipeline in the horizontal or vertical direction exceeding the displacement limit value can be monitored.

The first end of the first magnet 21 is arranged at the central axis position of the first magnetically controlled monitoring ring 301, and the second end is fixedly connected to the pipeline 1 to be tested. The first magnet 21 generates corresponding displacement with the displacement of the pipeline 1 to be tested; so that when the displacement of the pipeline 1 to be tested in the horizontal direction reaches the displacement limit value, the first magnet 21 can timely trigger the first magnetically controlled monitoring ring 301 to generate a displacement signal, so as to achieve the technical effect of timely knowing that the displacement of the pipeline 1 to be tested has reached the displacement limit value, and a pipeline accident may occur and the staff needs to deal with it in time.

[0083] On this basis, the second magnetically controlled monitoring ring 302 is arranged in a vertical direction at a set distance from the pipeline 1 to be tested, and the central axis position is arranged in a horizontal direction at a set distance from the pipeline 1 to be tested, so as to realize the displacement monitoring of the pipeline 1 to be tested in the vertical direction. The first end of the second magnet 22 is arranged at the central axis position of the second magnetically controlled monitoring ring 302, and the second end is fixedly connected to the pipeline 1 to be tested, and the second end of the second magnet 22 is fixedly connected to the second end of the first magnet 21.

[0084] The first magnet 21 and the second magnet 22 simultaneously generate corresponding displacements with the displacement of the pipeline 1 to be tested; so that when the displacement of the pipeline 1 to be tested in the vertical direction reaches the displacement limit value, the second magnet 22 can timely trigger the second magnetically controlled monitoring ring 302 to generate a displacement signal, so as to achieve the technical effect of timely knowing that the displacement of the pipeline 1 to be tested has reached the displacement limit value, and a pipeline accident may occur and the staff needs to deal with it in time. Since the second end of the first magnet 21 is fixedly connected to the second end of the second magnet 22 and is fixedly connected to the pipeline 1 to be tested through the mounting bracket, the displacement of the pipeline in the horizontal or vertical direction exceeding the displacement limit value can be monitored.
