Description

Technical Field

[0001] The invention relates to the technical field of electrical detection devices, in particular to an electrical detection device for a thermal power plant which is easy to install. Background Art

[0002] The electrical equipment in thermal power plants operates for a long time and is affected by many factors, such as insulation aging, mechanical wear, overload, etc., which may cause failures. Regular inspections can detect potential failures in advance, such as reduced insulation resistance, abnormal grounding resistance, insufficient electrical clearance, etc., and repair them in time to avoid the failure from developing into serious accidents such as short circuits, leakage, fire, etc., to ensure the safety of personnel lives and equipment property.

[0003] Routine electrical device inspection requires maintenance personnel to inspect the appearance of the electrical device. Some existing substations are at a high height. When conducting daily inspections, maintenance personnel need to climb, which is quite dangerous. For example, China's authorized patent for an electrical inspection device for electrical equipment in a substation (application number: 202220416349.3) discloses an electrical inspection device for electrical equipment in a substation. By setting a first hollow tube, a second hollow tube and a third hollow tube, the probe can be lifted to a higher place for inspection when visual inspection of electrical devices at a higher place is required. It is safer without climbing. At the same time, by setting a bracket, a disc, a bearing seat, a winding tube and a through-port, the connecting wire passes through the connecting seat and the disc, and comes out from the through-port on the winding tube. The rotating turntable drives the winding tube to rotate, which is beneficial for the winding tube to wind the connecting wire, and it is convenient to store the connecting wire, which is more convenient, thereby facilitating the placement and installation of the detection device as a whole.

[0004] Another example is a Chinese authorized patent for an electrical detection device (application number: 202223424612.2), which discloses an electrical detection device. By setting a vertical electric push rod and a horizontal electric push rod, the electrical detection device can not only detect electrical equipment at a higher place by controlling the vertical electric push rod, but also control the horizontal electric push rod to drive the connecting block to move, and further drive the detection probe to move, so that the detection probe can move freely in the horizontal direction. At the same time, the working state of the detection probe becomes vertical, so as to detect the top of the electrical equipment at a higher place, thereby increasing the detection range.

[0005] Although the existing technology can increase the detection range, allowing maintenance personnel to better observe the appearance of higher electrical devices, it is easy to miss some potential fault hazards by only observing the appearance of electrical equipment to determine whether there is an abnormality, such as insulation aging and poor contact of electrical equipment, which leads to the gradual development of these fault hazards and ultimately leads to equipment failure.

The input end of the control base 6 is connected to the wire 5, and the output end of the control base 6 is connected to a detection probe 8 and a lateral telescopic device 9. The lateral telescopic device 9 is installed at the top of the control base 6, and a detection probe 8 is fixedly installed at one end of the lateral telescopic device 9.

[0027] In addition, compared with the prior art, the support connection frame 10 provided at the bottom end of the detection probe 8 can also provide support for the detection probe 8 all the time, thereby reducing the wear of the detection probe 8 and extending the service life of the detection probe 8 .

[0028] In this embodiment, if Figures 2 to 6As shown, the sliding assembly includes guide protrusions 14 arranged on both sides of the temperature probe 13, one end of the guide protrusions 14 is fixedly installed on one side of the temperature detector 11, one side of the guide protrusions 14 is slidably installed with a guide slider 15, the other side of the guide slider 15 is fixedly installed with a sliding end 16, the inner wall of the sliding end 16 is rotatably installed with a torque shaft 17, the bottom end of the torque shaft 17 is fixedly installed with a separation roller 18, the side of the separation roller 18 close to the temperature detector 11 is provided with a buffer assembly, and both sides of the separation roller 18 are provided with separation assemblies. With this design, after the maintenance personnel complete the detection of one position of the electrical device, they can directly move the mobile base 1 horizontally and directly proceed to the detection of the next position without the need to perform positioning adjustment again, thereby reducing the operation steps and improving work efficiency.

[0029] In this embodiment, if Figures 4 to 6 As shown, the buffer assembly includes a first abutment block 19 arranged on the side of the separation roller 18 close to the temperature detector 11, and a push block 20 is fixedly installed on the end of the first abutment block 19 away from the separation roller 18. The push blocks 20 are slidably installed on the inner wall of the temperature detector 11, and the push blocks 20 and the inner wall of the temperature detector 11 are connected by a first spring 21. With this design, when the temperature probe 13 is controlled to approach the electrical device, the temperature detector 11 squeezes the first spring 21, so that the first spring 21 drives the first abutment block 19 to move, and the first abutment block 19 abuts against the separation roller 18 and drives the separation roller 18 to move, so that the separation roller 18 first abuts against the surface of the electrical device for positioning, thereby preventing the temperature probe 13 and the surface of the electrical device from squeezing each other and causing damage to the temperature probe 13.

[0030] In this embodiment, if Figures 4 to 6 As shown, the separation assembly includes a separation scraper 22 arranged on both sides of the separation roller 18, the separation scraper 22 is fixedly installed on the inner wall of the sliding end 16, the bottom end of the separation scraper 22 is slidably installed with a switch slider 23, one side of the switch slider 23 is provided with a switch assembly, the top of the switch slider 23 is provided with a through groove 24, the bottom end of the switch slider 23 is installed with a dust collecting pipe 25, the bottom end of the dust collecting pipe 25 is installed with a dust collecting box 26, and one side of the dust collecting box 26 is provided with a sliding cover. When a certain amount of dust is collected in the dust collecting box 26, the maintenance personnel can The dust box 26 is opened by sliding the cover to pour out the dust therein. The dust box 26 is slidably installed on the bottom end of the temperature detector 11. With this design, when the maintenance personnel moves the movable base 1 to rotate the separation roller 18, one end of the separation scraper 22 abuts against one side of the separation roller 18, thereby separating the dust on the surface of the separation roller 18, and collecting the separated dust through the dust box 26, preventing dust from accumulating on the surface of the separation roller 18, reducing the adsorption effect of the separation roller 18, and further affecting the detection effect of the first detection mechanism and the second detection mechanism.

[0031] In this embodiment, if Figures 4 to 7 As shown, the switch assembly includes a second spring 27 arranged on one side of the switch slider 23, and a triangular block 28 is fixedly installed on the other side of the switch slider 23. One side of the triangular block 28 is abutted with a second abutting block 29, and the inner side of the second abutting block 29 is fixedly installed with a turntable 30. With this design, on the one hand, when the device is not working, the second spring 27 releases elastic potential energy to push the switch slider 23 to abut against the turntable 30, so that the through groove 24 is located on one side of the bottom end of the separation scraper 22, preventing the vibration generated when the movable base 1 is moved for positioning, causing the dust in the dust box 26 to move to the separation roller 1 8, which affects the operation of the separation roller 18. On the other hand, when the separation component is working, the separation roller 18 drives the turntable 30 to rotate, and the turntable 30 drives the second abutment block 29 to rotate. One end of the second abutment block 29 abuts against the triangular block 28 and drives the triangular block 28 to move away from the turntable 30. The triangular block 28 drives the switch slider 23 to move, and the switch slider 23 drives the through groove 24 to move, so that the through groove 24 moves to the bottom end of the separation scraper 22, so that the dust separated by the separation scraper 22 can move to the dust collecting box 26 through the through groove 24 and the dust collecting pipe 25.

[0032] Furthermore, in the present embodiment, a connecting arc block 31 is fixedly installed at the bottom end of the first abutment block 19, and a baffle 32 is fixedly installed at one end of the connecting arc block 31, and the baffle 32 abuts against one end of the second abutment block 29. With this design, when the maintenance personnel push the movable base 1 to move a long distance, one end of the second abutment block 29 abuts against the baffle 32, thereby preventing the second abutment block 29 from rotating at a large angle, so that the switch slider 23 moves to one side of the second abutment block 29 under the push of the second spring 27, causing the dust box 26 to close prematurely, affecting the dust collection effect of the separation component, and making it difficult to drive the switch slider 23 to reset.

[0033] Furthermore, in the present embodiment, the turntable 30 includes a connecting shaft 33, the top end of the connecting shaft 33 is fixedly mounted on the bottom end of the separation roller 18, a pair of fixed rods 34 are fixedly mounted on the outer wall of the connecting shaft 33, a rotating block 35 is rotatably mounted on one side of the fixed rod 34, one end of the rotating block 35 abuts against a third abutting block 36, the third abutting block 36 is fixedly mounted on the inner wall of the turntable 30, a fixed block 37 is mounted on one side of the rotating block 35, the fixed blocks 37 are fixedly mounted on the outer wall of the connecting shaft 33, the rotating block 35 and the fixed block 37 are connected by a third spring 38, and with this design, when the separation roller 18 rotates, the separation roller 18 drives the connecting shaft 33 to rotate, the connecting shaft 33 drives the fixed rod 34 to rotate, the fixed rod 34 drives the rotating block 35 to rotate, and the rotating The movable block 35 drives the third abutment block 36 to rotate, thereby driving the turntable 30 to rotate, so that the turntable 30 can drive the second abutment block 29 to rotate, and when the second abutment block 29 abuts against the baffle plate 32, the separation roller 18 continues to drive the rotating block 35 to rotate by connecting the rotating shaft 33 and the fixed rod 34. At this time, the third abutment block 36 abuts against the rotating block 35 and drives the rotating block 35 to rotate in the direction away from the fixed block 37. The rotating block 35 drives the third spring 38 to undergo elastic deformation and accumulate elastic potential energy. When the rotating block 35 moves to the other side of the third abutment block 36, the third spring 38 releases the elastic potential energy, undergoes elastic deformation, and drives the rotating block 35 to rotate toward the fixed block 37, so that when the baffle plate 32 blocks the second abutment block 29, it will not affect the rotation of the separation roller 18, thereby improving the stability and reliability of the device.

[0034] Furthermore, in the present embodiment, one side of the first abutment block 19 close to the separation roller 18 is arranged to be in an arc shape matching the outer wall of the separation roller 18, and a sliding round rod 39 is fixedly installed on the top of the first abutment block 19, and the sliding round rod 39 is slidably installed on the inner wall of the limiting groove 40, and the limiting groove 40 is opened on the inner wall of the sliding end 16. Through such a design, in cooperation with the torque shaft 17, when the second detection mechanism is positioned, the first abutment block 19 can abut and squeeze the separation roller 18, so that the torsion spring arranged in the torque shaft 17 is difficult to drive the separation roller 18 to rotate, and after the detection is completed, the maintenance personnel manipulates the lateral telescopic device 9 to drive the detection probe 8 to reset, and at this time, the first abutment block 19 leaves one side of the separation roller 18 and stops abutting against the separation roller 18, so that the torque shaft 17 can drive the separation roller 18 to automatically reset.
