[0046] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a 660MW thermal power unit maintenance warning device 100, including a control module 110, a warning box 120, a first electrical contact assembly 130 arranged in the warning box 120, a second electrical contact assembly 140, a lifting drive assembly 150 and an alarm 160.

[0048] The control module 110 is electrically connected to the alarm 160 , the first electrical contact assembly 130 and the lifting drive assembly 150 , respectively.

[0049] The first electrical contact assembly 130 is fixed to the inner top wall of the warning box 120 .

[0050] The lifting driving assembly 150 is connected to the second electrical contact assembly 140 to drive the second electrical contact assembly 140 to lift and lower.

[0051] The control module 110 is used to control the lifting drive component 150 to drive the second electrical contact component 140 to rise to electrical contact with the first electrical contact component 130 when receiving an abnormal operation signal of the thermal power unit, so as to achieve circuit conduction of the alarm 160 and then control the alarm to sound an alarm.

[0052] It should be noted that, in this embodiment, the alarm 160 can be an audible and visual alarm, and the alarm 160 is arranged on the outer top of the warning box 120. Ventilation windows 121 are also arranged on both sides of the warning box 120 for ventilation and heat dissipation. The warning box 120 can be installed at the corresponding position of the thermal power unit.

[0053] The maintenance warning device of the 660MW thermal power unit of the disclosed embodiment has a control module which, upon receiving a signal indicating abnormal operation of the thermal power unit, controls the lifting and lowering drive assembly to drive the second electrical contact assembly to rise to make electrical contact with the first electrical contact assembly, thereby achieving circuit conduction of the alarm, and further controlling the alarm to sound an alarm, thereby achieving real-time monitoring of the working condition of the thermal power unit, facilitating real-time understanding of the working condition of the thermal power unit, and being faster and more effective, thereby improving the monitoring efficiency and accuracy of the warning device of the maintenance warning system; achieving circuit conduction of the alarm by electrical contact between the first electrical contact assembly and the second electrical contact assembly can ensure the stability of the contact of the warning device contacts, thereby improving the safety of the line contact of the warning device.

[0054] For example, Figure 3 As shown, the first electrical contact assembly 130 includes a first contact seat 131 and a plurality of first electrical contacts 132 spaced apart from each other in the first contact seat 131 .

[0055] The second electrical contact assembly 140 includes a second contact seat 141 and a plurality of second electrical contacts 142 spaced apart from each other in the second contact seat 141. The first electrical contact 132 and the second electrical contact 142 correspond to each other and realize circuit conduction of the alarm 160 after contacting each other.

[0056] like Figure 3 As shown, the shapes of the first electrical contact 132 and the second electrical contact 142 match, the first electrical contact 132 is concave, and the second electrical contact 142 is convex. When the first electrical contact 132 and the second electrical contact 142 are electrically connected, the second electrical contact 142 is clamped on the first electrical contact 132. The shapes of the first electrical contact 132 and the second electrical contact 142 are not specifically limited in this embodiment and can be selected according to actual needs.

[0057] It should be noted that the number and distribution of the first electrical contacts 132 and the second electrical contacts 142 are not specifically limited in this embodiment and can be selected according to actual needs.

[0058] The lifting drive assembly 150 includes a first driving cylinder 151 and a support frame 152 . The first end of the support frame 152 is connected to the first driving cylinder 151 , and the second end of the support frame 152 is connected to the second contact seat 141 .

[0059] The first driving cylinder 151 is electrically connected to the control module 110 .

[0060] Specifically, when the control module 110 receives the abnormal operation signal of the thermal power unit, it controls the first driving cylinder 151 to start, and the first driving cylinder 151 drives the support frame 152 to rise and then drives the second contact seat 141 to rise to electrically contact with the first contact seat 131.

[0061] In this embodiment, the first electrical contact component 130 and the second electrical contact component 140 are arranged to be distributed contact. After the control module 110 receives the early warning signal, the first driving cylinder 151 drives the first contact seat 131 to contact the second contact seat 141, which can ensure the stability of the contact of the early warning device contacts and improve the safety of the line contact of the early warning device.

[0062] For example, Figure 4 As shown, the 660MW thermal power unit maintenance warning device 100 also includes a guide frame 170 arranged in the warning box 120.

[0063] The second contact seat 141 slides and rises along the guide frame 170. Specifically, the guide frame 170 is provided with a sliding groove in the vertical direction, and a slider is slidably provided in the sliding groove, and the slider is connected to the second contact seat 141, so that the second contact seat 141 slides and rises along the guide frame 170.

[0064] A limit stopper 171 is disposed on the top of the guide frame 170 , and the limit stopper 171 is used to limit the rising position of the second contact seat 141 .

[0065] In this embodiment, the guide frame 170 can guide the first electrical contact assembly 130 and the second electrical contact assembly 140 during the contact process to ensure the accuracy of the contact position of the early warning device. At the same time, the limit baffle 171 limits the maximum stroke of the second contact seat 141 to avoid excessive contact of the contact head of the early warning device, thereby protecting the contact head of the early warning device to a certain extent.

[0066] For example, Figure 1 As shown, the 660MW thermal power unit maintenance warning device 100 also includes an image acquisition component 180 disposed in the warning box 120 .

[0067] The image acquisition component 180 is used to acquire the working status image of the thermal power unit in real time and transmit the acquired image to the control module 110 .

[0068] The control module 110 is further used to analyze the current working status of the thermal power unit according to the received image.

[0069] Specifically, Figure 1 As shown, the image acquisition component 180 includes a second driving electric cylinder 181 , a driving rod 182 and a monitoring camera 183 .

[0070] The first end of the driving rod 182 is connected to the second driving electric cylinder 181 , and the second end of the driving rod 182 is connected to the monitoring camera 183 .

[0071] The control module 110 is also used to control the second driving electric cylinder 181 to start up to drive the driving rod 182 to translate, so that the monitoring camera 183 extends to the outside of the early warning box 120 to obtain the working status image of the thermal power unit.

[0072] In this embodiment, the monitoring camera 183 is driven to extend to the monitoring position of the thermal power unit by the second driving electric cylinder 181, so that the working condition of the thermal power unit can be monitored in real time.

[0073] Exemplarily, as shown in the figure, the 660MW thermal power unit maintenance warning device 100 also includes a cleaning component 190 disposed in the warning box 120, and the cleaning component 190 is respectively connected to both sides of the second electrical contact component 140. In other words, the number of cleaning components 190 is two, and the two side walls of the warning box 120 can be cleaned.

[0074] When the second electrical contact component 140 is raised or lowered, the cleaning component 190 is driven to be raised or lowered, thereby enabling the cleaning component 190 to clean the inner wall of the warning box 120 .

[0075] In this embodiment, the inner wall of the warning box 120 can be cleaned by the cleaning component 190 to ensure the normal operation of the warning device.

[0076] In this embodiment, if Figure 5 As shown, the cleaning assembly 190 includes a linkage frame 191 , a gear rack structure 192 , a rotating structure 193 and a cleaning cylinder 194 .

[0077] The linkage frame 191 is connected to the second electrical contact assembly 140, and the gear rack structure 192 is disposed on the linkage frame 191. Specifically, the linkage frame 191 is connected to the second contact seat 141. The gear rack structure 192 includes a rack 192a and a gear 192b. The rack 192a is disposed on the linkage frame 191, and the gear 192b is meshedly connected with the rack 192a.

[0078] The first end of the rotating structure 193 is drivingly connected to the gear rack structure 192 , and the second end of the rotating structure 193 is connected to the cleaning cylinder 194 .

[0079] Specifically, the rotating structure 193 includes a rotating shaft 193a, a driving pulley 193b, a driven pulley 193c and a transmission belt 193d. The rotating shaft 193a is connected to the rack 192a and the driving pulley 193b respectively. The two ends of the transmission belt 193d are connected to the driving pulley 193b and the driven pulley 193c respectively, and the driven pulley 193c is connected to the cleaning cylinder 194.

[0080] The gear rack structure 192 converts the lifting motion of the linkage frame 192 into a rotational motion, and drives the rotation structure 193 to rotate, thereby causing the cleaning cylinder 194 to rotate to complete the corresponding cleaning action.

[0081] Specifically, the lifting motion of the linkage frame 192 is converted into the rotation motion of the gear rack structure 192, which drives the rack 192a to rotate, drives the rotating shaft 193a to rotate, and then drives the driving pulley 193b to rotate. The driving pulley 193b rotates through the transmission belt 193d to drive the driven pulley 193c to rotate, and then drives the cleaning cylinder 194 to rotate, so as to clean the inner wall of the early warning box 120.

[0082] For example, Figure 1 As shown, the 660MW thermal power unit maintenance warning device 100 also includes a wire management component 200 disposed at the bottom of the warning box, and the wire management component 200 is used to store the transmission lines in the warning box 120.

[0083] Specifically, Figure 6 As shown, the cable management assembly 200 includes a cable management frame 210 disposed on the inner side wall of the warning box 120, a fixed clamping seat 220 disposed on the cable management frame 210, and a movable clamping seat 230 engaged with the fixed clamping seat 220; wherein, after the fixed clamping seat 220 and the movable clamping seat 230 are engaged, a plurality of receiving holes 240 are formed at the contact point. The receiving holes 240 are used to place the transmission line.

[0084] It should be noted that there is no specific limitation on the number of the cable management components 200 , and the number can be selected according to actual needs.

[0085] In this embodiment, by setting a fixed card seat and a movable card seat, the transmission line of the early warning device is placed between the fixed card seat and the movable card seat, and the transmission line of the monitoring early warning device is tightened to avoid entanglement of the transmission line of the early warning device during maintenance.

[0086] For example, Figure 7 As shown, the control module 110 is disposed on the outer wall of the warning box 120. The control module 110 includes a receiving unit 111, an analyzing unit 112, a control unit 113 and an output unit 114 which are communicatively connected in sequence.

[0087] The receiving unit 111 can be used to receive the working condition image of the thermal power unit obtained by the monitoring camera 183. The analyzing unit 112 can be used to analyze the working condition image of the thermal power unit. The control unit 113 can control the opening and closing of each driving electric cylinder and the opening and closing of the alarm. The output unit 114 can output each analysis result.

[0088] The maintenance warning device for a 660MW thermal power unit of the disclosed embodiment solves the problem that traditional maintenance warning devices require regular manual maintenance, thereby improving monitoring efficiency and accuracy.
