[Technical field]

[0001] The present invention relates to the technical field of thermal power unit inspection, and in particular to an early warning device for thermal power unit inspection. [Background technology]

[0002] Thermal power generation is a power generation method in which thermal energy generated when combustibles are burned is converted into electrical energy by a power generating device. It is based on coal-fired power generation units, and when the coal-fired power generation units are in use, their system status must be monitored to achieve the purposes of fault diagnosis, early warning and monitoring of the coal-fired power generation units, so that faults can be detected and eliminated in a timely manner.

[0025] 1 to 9, embodiment 1 is a first embodiment of the present invention, which provides an inspection early warning device for a thermal power generation unit.

[0026] In use, the monitoring assembly 201 monitors the thermal power generating unit in real time. When an abnormality of the thermal power generating unit is monitored, the monitoring assembly 201 connects the rising trigger assembly 203 to the fixed trigger assembly 202 to timely provide an early warning. In the process of connecting the rising trigger assembly 203 to the fixed trigger assembly 202, the transmission assembly 204 drives the wiping assembly 205 to clean the rising trigger assembly 203, thereby ensuring good contact between the rising trigger assembly 203 and the fixed trigger assembly 202. Due to the installation of the pressure adjusting assembly 206, when the connection pressure between the rising trigger assembly 203 and the fixed trigger assembly 202 is not appropriate, it can be detected and displayed in a timely manner, and can even be immediately adjusted, thereby ensuring good contact between the rising trigger assembly 203 and the fixed trigger assembly 202 and avoiding separation or excessive contact during connection.

[0027] 2-9, the second embodiment is a second embodiment of the present invention, which is different from the first embodiment in the following points: The monitoring assembly 201 includes a horizontal cylinder 201a installed on the inner wall of the housing 101, and a monitoring camera 201b installed on the horizontal cylinder 201a, where one end of the horizontal cylinder 201a is fixedly connected to the inner wall of the housing 101, and the other end of the horizontal cylinder 201a passes through the filter 104 and is fixedly connected to the monitoring camera 201b via a connecting member, and the monitoring camera 201b moves to a monitoring position of the thermal power generation unit by the horizontal cylinder 201a and monitors the position in real time, so as to timely issue an early warning when an abnormality occurs.

[0028] Further, the fixed trigger assembly 202 includes a fixed plate 202a provided on the inner wall of the housing 101, a contact base 202b provided on the fixed plate 202a, and an audio / optical alarm 202c provided in the housing 101, where the fixed plate 202a is fixedly connected to the inner wall of the housing 101, the contact base 202b is fixedly connected to the bottom of the fixed plate 202a, and at least four of them are provided, and the audio / optical alarm is fixedly connected to the top of the housing 101. With the installation of the audio / optical alarm, when the monitoring camera 201b detects an abnormality in the thermal power generation unit, an early warning can be issued in a timely manner.

[0029] Furthermore, the lifting trigger assembly 203 includes a connection plate 203a provided on the inner wall of the housing 101 and located below the contact stand 202b, a vertical cylinder 203b provided on the connection plate 203a, and a screw knob 203c provided on the vertical cylinder 203b, wherein the connection plate 203a and the inner wall of the housing 101 are fixedly connected, the vertical cylinder 203b is fixedly connected to the bottom of the connection plate 203a, and the output end of the vertical cylinder 203b passes through the connection plate 203a and is rotatably connected to the bottom end of the screw knob 203c via a bearing.

[0030] In addition, the lifting trigger assembly 203 further includes a screw 203d on the screw knob 203c, two slide grooves 203e on the inner wall of the housing 101, a movable plate 203f on the screw 203d and connected to the slide groove 203e, and a contact header 203g on the movable plate 203f and fitted with the contact platform 202b, where the bottom end of the screw 203d is fixedly connected to the top end of the screw knob 203c, the slide groove 203e is fixedly connected to the inner wall of the housing 101, and the two slide grooves 203e are located on both sides of the fixed plate 202a, respectively, and the movable plate 203f is slidably connected to the slide groove 203e through a slider, and the slide groove 203e is fixed to the inner wall of the housing 101. By installing the groove plate 203e, the stability of the movement of the movable plate 203f and the contact headers 203g can be improved, the number of contact headers 203g matches the number of contact tables 202b, the four contact headers 203g and the four contact tables 202b are all positioned vertically corresponding to each other, the contact tables 202b are formed in a "concave" shape with an opening facing downward, and the contact headers 203g are formed in a "convex" shape, which perfectly matches the shape of the contact tables 202b, the contact tables 202b have a "concave" shape with an opening facing downward, and a fixed plate 202a for shielding is provided above it, so that ash dust is less likely to adhere, and therefore, in the subsequent cleaning work, the contact headers 203g only need to be cleaned by the wiping assembly 205.

[0031] In addition, the transmission assembly 204 includes two extension plates 204a provided on the movable plate 203f, a lead screw 204b provided on the extension plates 204a, a pinion 204c provided on the lead screw 204b, and a rack 204d provided on the inner wall of the housing 101 and meshing with the pinion 204c, where the two extension plates 204a are fixedly connected to the backs of both sides of the movable plate 203f respectively, the extension plate 204a is rotatably connected to the outer surface of the lead screw 204b through a bearing, one end of the lead screw 204b is fixedly connected to the pinion 204c, and the other end of the lead screw 204b is provided with a position limiting block, so as to prevent the wiping assembly 205 from moving away from the lead screw 204b when moving for wiping, and two racks 204d are provided, and the two racks 204d are meshed with the two pinions 204c respectively. Furthermore, the rack 204d is fixedly connected to the inner wall of the housing 101. With the installation of the transmission assembly 204, when the monitoring camera monitors the abnormality of the thermal power generation unit and controls the vertical cylinder 203b to drive the contact header 203g to connect to the contact table 202b, the wiping assembly 205 can be driven in advance to clean the contact header 203g, so as to ensure good contact between the contact header 203g and the contact table 202b. Furthermore, when the operator grasps the early warning situation and controls the vertical cylinder 203b to separate the contact header 203g from the contact table 202b, the installation of the transmission assembly 204 can also clean the contact header 203g again, effectively avoiding poor contact caused by the adhesion of foreign matter such as ash dust to the contact header 203g.

[0032] The rack 204d is made long enough to rotate the pinion 204c exactly two times, and the threaded rod on the lead screw 204b moves the connection frame 205a a distance just enough for the wiping case 205b to completely clean the contact header 203g and remain in front of the contact header 203g.

[0033] Further, the wiping assembly 205 includes a connection frame 205a disposed between the two lead screws 204b, a wiping case 205b disposed on the connection frame 205a, and a wiper 205c disposed on the wiping case 205b, and a U-shaped holder 205d is disposed on the wiping case 205b, and a roller 205e is disposed on the U-shaped holder 205d, where both sides of the front of the connection frame 205a are respectively thread-connected to the two lead screws 204b through threaded holes, and the threads on the outer surfaces of the two threaded rods are oppositely provided, and they are integrally the same in shape and size as the contact base 202b, so that the wiper 205c is connected to the wiping case 205b to perform pressure adjustment by the pressure adjustment assembly 206, and the U-shaped holder 205d is fixedly connected to the wiping case 205b, and the roller 205e is fixedly connected to the U-shaped holder 205d. The wiper 205e is fitted into the U-shaped holder 205d and rotatably connected thereto. During the connection of the contact header 203g with the contact base 202b, the wiper 205c is located in front of the contact header 203g after performing the wiping action, so that the normal connection between the contact header 203g and the contact base 202b is not blocked. However, since the contact header 203g is connected by the pressure spring 206e in the pressure adjustment assembly 206, when the wiping case 205b is separated from the contact header 203g, the contact header 203g is slightly raised upward a certain distance under the influence of the elastic force. Furthermore, due to the installation of the roller 205e, when the contact header 203g and the contact base 202b are separated and the wiping case 205b returns, the contact header 203g can be pushed down so that the contact header 203g is just inserted into the wiping case 205b.

[0034] Further, the pressure adjustment assembly 206 includes a screw sleeve 206a provided on the screw 203d, a connection holder 206b provided on the screw sleeve 206a, an accommodating groove 206c provided on the movable plate 203f and fitted with the contact header 203g, an adjustment plate 206d provided inside the accommodating groove 206c and connected to the connection holder 206b, and a pressure spring 206e provided on the adjustment plate 206d and connected to the contact header 203g. A position limiting plate 206f is provided on the inner wall of the accommodating groove 206c, a pressure detector 206g is provided on the wiping case 205b, and a pressure display device 206h is provided on the screw sleeve 206a. Here, the screw sleeve 206a and the screw 203d are threadedly connected, the accommodating groove 206c is opened at the top of the movable plate 203f, the adjusting plate 206d is movably connected in the accommodating groove 206c, the numbers of the pressure detector 206g, the adjusting plate 206d, the accommodating groove 206c and the connecting holder 206b all match the number of the contact header 203g, the bottom end of the pressure spring 206e is fixedly connected to the top of the adjusting plate 206d, the top end of the pressure spring 206e is fixedly connected to the bottom of the contact header 203g, and each adjusting plate 206d is provided with at least three pressure springs 206e, and the position limiting plate 206f is located below the contact header 203g.

[0035] If the pressure of the spring below the contact header 203g is insufficient or uneven, poor contact of the contact header 203g may occur and an arc may be generated, and under the prolonged action of the arc, the contact header 203g may be welded and lead to excessive contact. Therefore, the pressure of the pressure spring 206e needs to be checked regularly to ensure that it meets the manufacturer's specifications. If the pressure of the pressure spring 206e becomes insufficient, the spring needs to be adjusted or replaced to ensure that there is sufficient contact pressure on the contact header 203g.

[0036] When the contact header 203g is connected to the contact base 202b, the contact base 202b is fixed so as not to move. Therefore, when the contact header 203g comes into contact with and connects to it, it receives the force of the contact base 202b and moves downward, pressing the pressure spring 206e. Furthermore, by installing the position limiting plate 206f, the distance that the contact header 203g moves downward is limited, thereby preventing excessive contact between the contact header 203g and the contact base 202b.

[0037] The pressure detector 206g is communicatively connected to the pressure display device 206h, and the pressure of the pressure spring 206e can be detected in real time by the pressure detector 206g and displayed on the pressure display device 206h, thereby allowing the operator to easily observe and make corresponding adjustments.

[0038] The wiping case 205b is provided with a pressure detector 206g, which detects the pressure of the pressure spring 206e and is used to divide the wiper 205c into two parts, one part of the wiper 205c is directly connected to the wiping case 205b, and the other part is shaped to match the bottom of the pressure detector 206g and connected to the bottom of the pressure detector 206g, thereby avoiding the influence of the pressure detector 206g on the accuracy of the detection of the pressure spring 206e.

[0039] Furthermore, the fastening assembly 207 includes two fixed blocks 207a provided inside the housing 101, a fixed locking base 207b provided on the fixed blocks 207a, a movable locking base 207c provided on the fixed locking base 207b, and an engagement groove 207d provided on the fixed locking base 207b and the movable locking base 207c, where the two fixed blocks 207a are fixedly connected to the inner wall and the bottom of the internal cavity of the housing 101, respectively, and the fixed locking base 207b is fixedly connected to the fixed blocks 207a. The movable locking base 207c and the fixed locking base 207b are connected via bolts, and both the fixed locking base 207b and the movable locking base 207c are provided with a number of engagement grooves 207d, and the engagement grooves 207d on the fixed locking base 207b and the movable locking base 207c are arranged opposite each other. Furthermore, when the fixed locking base 207b is connected to the movable locking base 207c, these engagement grooves 207d are formed as perfect circular grooves, thereby engaging and tightening the transmission line of the early warning system 103.

[0040] During use, the housing 101 is attached to the thermal power generation unit, and the monitoring camera 201b is driven by the horizontal cylinder 201a to reach a monitoring position of the thermal power generation unit, whereby the monitoring camera 201b monitors the working status of the thermal power generation unit in real time, and if the monitoring camera 201b detects abnormal operation of the thermal power generation unit, it controls to activate the vertical cylinder 203b, and drives the movable plate 203f and the contact header 203g to move them upward until they are completely aligned with the contact base 202b within the slide groove plate 203e, at which point the circuit of the acoustic and optical alarm is turned on and the acoustic and optical alarm issues an early warning.

[0041] During the process of the contact header 203g and the movable plate 203f moving upward, the wiping case 205b, the connecting frame 205a, the lead screw 204b and the pinion 204c are driven to move upward synchronously. During the process of the pinion 204c moving upward, the pinion 204c rotates in combination with the rack 204d. The rotation of the pinion 204c drives the rotation of the lead screw 204b, so that the connecting frame 205a, the wiping case 205b and the wiper 205c slide over the contact header 203g to clean it and then remain in front of the contact header 203g. After the wiping case 205b has completed cleaning of the contact header 203g, the contact header 203g continues to move upward and is directly connected to the contact stand 202b, and the audio and optical alarm is turned on. When the contact header 203g and the contact base 202b are connected, the contact base 202b is fixed so as not to move. Therefore, when the contact header 203g comes into contact with and connects to it, it receives the force of the contact base 202b and moves downward, pressing the pressure spring 206e. Furthermore, by installing the position limiting plate 206f, the distance that the contact header 203g moves downward is limited, thereby preventing excessive contact between the contact header 203g and the contact base 202b.

[0042] On the contrary, when the vertical cylinder 203b is controlled to drive the contact header 203g to return, the contact header 203g and the movable plate 203f move downward, and the pinion 204c rotates in the opposite direction correspondingly, causing the lead screw 204b to rotate in the opposite direction, thereby driving the wiping case 205b to move toward the contact header 203g. After the wiping case 205b wipes and cleans the contact header 203g before, and separates from the contact header 203g, the contact header 203g is slightly raised upward a certain distance under the influence of the elastic force of the pressure spring 206e, so that the contact header 203g is separated from the contact base 202b by the installation of the roller 205e, and when the wiping case 205b returns, the contact header 203g is pushed down, so that the contact header 203g just enters the wiping case 205b.

[0043] Under normal conditions of the thermal power generation unit, the wiping case 205b is always connected to the contact header 203g, and when an abnormality in the pressure of the pressure spring 206e is detected by the pressure detector 206g, it is displayed on the pressure display device 206h, so that the operator can easily observe and make adjustments. In order to ensure that there is sufficient contact pressure in the contact header 203g, the pressure of the pressure spring 206e can be adjusted by rotating the screw knob 203c to drive the screw sleeve 206a, the connection holder 206b and the adjustment plate 206d to move upward, thereby ensuring good contact between the contact header 203g and the contact base 202b.

[0044] The other structure is the same as that of the first embodiment.

[0045] Referring to Fig. 10, embodiment 3 is a third embodiment of the present invention, which is different from embodiment 2 in the following respects: the early warning system 103 includes a signal receiving module, an analysis module, a control module and an output module, the signal receiving module, the analysis module, the control module and the output module are communicatively connected in sequence, the control module is communicatively connected to the power sources of the horizontal cylinder 201a and the vertical cylinder 203b, where the control module is used to control the start and stop of the horizontal cylinder 201a and the vertical cylinder 203b, the signal receiving module feeds back the monitored information to the early warning system 103, and the analysis module of the monitoring and early warning system 103 analyzes the working status of the thermal power generation unit.

[0046] When in use, the method for using the thermal power generation unit inspection early warning system includes the following steps 1 to 5.
