[0002] Waste-to-energy incineration is a technology that converts municipal solid waste into electricity through high-temperature incineration. Its core is to achieve waste reduction, harmlessness and resource utilization through energy conversion. Municipal solid waste is burned at a high temperature of over 850°C in the incinerator, releasing chemical energy and converting it into heat energy. The heat energy is used to generate high-temperature steam through a waste heat boiler, which drives a steam turbine to convert the heat energy into mechanical energy, and finally the generator outputs electrical energy.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] This utility model provides a safety monitoring device for transmission lines in waste incineration power generation. The device includes a data server, a main control terminal, and at least one monitoring module. The monitoring modules are set along the transmission line and are used to monitor the current magnitude in the transmission line. The data server is signal-connected to each monitoring module to store the current data monitored by the monitoring module. The main control terminal is signal-connected to the data server and is used to analyze and process the current data collected by the monitoring modules. Based on the analysis and processing results, it can be determined whether the transmission line is operating safely.

[0031] Please see Figure 1 The monitoring module includes a sensor 100 and a monitor 200. The sensor 100 includes a first fixing plate 101 and a second fixing plate 102, which are symmetrically arranged to form a through hole 103 for the power transmission line to pass through. A first sensing capacitor 104 is disposed within the first fixing plate 101, and a second sensing capacitor 105 is disposed within the second fixing plate 102. The monitor 200 includes a protective housing and a current sensor, a control chip, and a signal transceiver housed within the housing. The control chip is electrically connected to the current sensor and the signal transceiver. The current sensor is connected to the first sensing capacitor 104 via a first connecting wire 300 and to the second sensing capacitor 105 via a second connecting wire 400. A data server is connected to the signal transceiver of each monitor 200. The first connecting wire 300 and the second connecting wire 400 pass through the protective shell and are connected to the current sensor. The current sensor detects whether there is current flowing between the two sensing capacitors and the magnitude of the current, and feeds back the detection result to the control chip. The control chip feeds back the detection result to the data server through a signal transceiver.

[0032] In this embodiment, the first fixing plate 101 and the second fixing plate 102 are installed on the outside of the transmission line. When current flows inside the transmission line, an induced current is formed between the two sensing capacitors. The monitoring module detects the occurrence of the induced current in the sensing capacitors and feeds the data back to the data server. The main control terminal judges the magnitude of the current inside the transmission line based on the intensity of the induced current received by the data server, thereby performing safety monitoring of the transmission line.

[0033] Please see Figure 2The first fixing piece 101 includes a first arched portion 106 and a first extension portion 107 extending radially from both sides of the first arched portion 106. The second fixing piece 102 includes a second arched portion 108 and a second extension portion 109 extending radially from both sides of the second arched portion 108. A first sensing capacitor 104 is disposed in the first arched portion 106, and a second sensing capacitor 105 is disposed in the second arched portion 108. The recessed areas of the first arched portion 106 and the recessed areas of the second arched portion 108 are opposite to each other to form a through hole 103. The first extension portions 107 on both sides of the first arched portion 106 and the second extension portions 109 on both sides of the second arched portion 108 correspond one-to-one and are fixedly connected by a snap-fit ​​assembly.

[0034] Please continue reading Figure 2 The first extension 107 has a plurality of first snap-fit ​​slots 110 along the length of the first fixing piece 101, and the second extension 109 has a plurality of second snap-fit ​​slots 111 along the length of the second fixing piece 102. The first snap-fit ​​slots 110 and the second snap-fit ​​slots 111 are arranged in a one-to-one correspondence. The snap-fit ​​assembly includes a plurality of snap-fit ​​members 114, which are arranged in a linear array along the length of the sensor 100. The two ends of each snap-fit ​​member 114 are snapped into the corresponding first snap-fit ​​slot 110 and second snap-fit ​​slot 111, respectively. The snap-fit ​​members 114 snap and fix the first fixing piece 101 and the second fixing piece 102, so that a through hole 103 is formed between the first fixing piece 101 and the second fixing piece 102. The power transmission line passes through the through hole 103, and the sensing capacitor in the first fixing piece 101 and the second fixing piece 102 can detect the working current in the power transmission line.

[0035] In one possible implementation, a first latching groove 110 extends from the top surface of the first extension 107 to the bottom surface, and the bottom of the first latching groove 110 slopes from the side surface of the first extension 107 towards the first arched portion 106. The depth of the first latching groove 110 gradually increases from the side surface of the first extension 107 to the first arched portion 106. A second latching groove 111 extends from the bottom surface of the second extension 109 to the top surface, and the bottom of the second latching groove 111 slopes from the side surface of the second extension 109 towards the second arched portion 108. The depth of the second latching groove 111 gradually increases from the side surface of the second extension 109 to the second arched portion 108. Please refer to [link to relevant documentation]. Figure 3The snap-fit ​​component 114 includes an intermediate connecting piece 115 and elastic locking pieces 116 disposed at both ends of the intermediate connecting piece 115. The elastic locking pieces 116 and the intermediate connecting piece 115 form a U-shaped structure, with the ends of the two elastic locking pieces 116 close to each other. One of the elastic locking pieces 116 of the snap-fit ​​component 114 snaps into the first snap-fit ​​groove 110 and is in close contact with the bottom of the first snap-fit ​​groove 110. The other elastic locking piece 116 of the snap-fit ​​component 114 snaps into the second snap-fit ​​groove and is in close contact with the bottom of the second snap-fit ​​groove 111. Since the distance between the ends of the two elastic locking pieces 116 of the snap-fit ​​component 114 is adjustable, the size of the through hole 103 formed by the first fixing piece 101 and the second fixing piece 102 is adjustable, thereby adapting to transmission lines of different diameters.

[0036] In one possible implementation, the bottom of both the first locking groove 110 and the second locking groove 111 is provided with a first anti-slip element, which is a soft rubber pad and / or an anti-slip pattern. In another possible implementation, a second anti-slip element is provided on one side of each of the two elastic locking pieces 116 facing each other, which is also a soft rubber pad and / or an anti-slip pattern. Providing anti-slip elements on the locking grooves and / or the elastic locking pieces 116 can improve the reliability of the locking engagement between the elastic locking pieces 116 and the locking grooves.

[0037] Please see Figure 1 The first sensing capacitor 104 is externally provided with a first insulating pad 112 for insulating and protecting the first sensing capacitor 104. The first connecting wire 300 passes through the first insulating pad 112 and is electrically connected to the first sensing capacitor 104. The second sensing capacitor 105 is externally provided with a second insulating pad 113 for insulating and protecting the second sensing capacitor 105. The second connecting wire 400 passes through the second insulating pad 113 and is electrically connected to the second sensing capacitor 105. The first insulating pad 112 and the second insulating pad 113 are made of rubber.

[0038] In use, the first fixing piece 101 is first placed on the top of the power transmission line, and the second fixing piece 102 is placed on the bottom of the power transmission line. At this time, the first extensions 107 on both sides of the first fixing piece 101 are opposite to the second extensions 109 on both sides of the second fixing piece 102. Then, the snap-fit ​​pieces 114 are inserted one by one into the first snap-fit ​​groove 110 on the first extension 107 and the second snap-fit ​​groove 111 on the second extension 109, thereby covering the first fixing piece 101 and the second fixing piece 102 to the outside of the power transmission line. When the snap-fit ​​connector 114 is inserted, the two elastic locking pieces 116 of the snap-fit ​​connector 114 first contact the bottom of the first snap-fit ​​groove 110 and the second snap-fit ​​groove 111, and then apply force to the intermediate connecting piece 115, so that the snap-fit ​​connector 114 moves closer to the sensing capacitor. The two elastic locking pieces 116 slide along the bottom of the groove until they abut against the side wall of the snap-fit ​​groove and are limited. During this process, the two elastic locking pieces 116 are pushed apart by the two fixing pieces and move away from each other. Under the action of the intermediate connecting piece 115, the two elastic locking pieces 116 have an elastic force that moves them closer to each other. This elastic force can be used to snap the two fixing pieces together. During the waste incineration power generation process, the transmission line transmits and collects the current generated by waste incineration. When the current flows through the transmission line and passes between the first fixed plate 101 and the second fixed plate 102, an induced current is generated between the first inductive capacitor 104 and the second inductive capacitor 105. The monitor 200 detects the induced current parameters and feeds the data back to the data server. The main control terminal judges the magnitude of the current inside the transmission line based on the current parameters received by the data server, thereby performing safety monitoring of the transmission line.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention.
