Description

Technical Field

[0001] The invention relates to the technical field of electric power testing, and in particular to a safety detection device for electric power construction. Background Art

[0002] Testing power safety during power construction can ensure power production and personal safety of workers, prevent accidents or reduce the damage and losses caused by accidents, and ensure the safe operation of the power system. In power construction work, any negligence may cause serious casualties and property losses. Therefore, real-time detection of current and voltage status in the surrounding environment during construction is crucial to ensure the safety of the power system and any safety of construction.

[0003] In the prior art, the safety detection device for power construction generally directly uses a manually held voltmeter to pre-test the voltage in the construction area to ensure that there is no high voltage current within the construction range. However, in some high-altitude power construction scenarios, it is necessary to use a hanging basket system for high-altitude operations.

When encountering larger obstacles, the construction workers can manually pull it. When encountering a concave area, the pressure detection module can be used for detection and early warning processing, so that the detection device can be applied to any situation in the construction area on the wall.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a safety detection device for electric power construction, comprising a safety detection device body and a construction hanging basket 1, the safety detection device body comprising a detection frame 2, a switching mechanism 3 and a synchronous detection component 4, the bottom of the detection frame 2 is integrally formed with a support plate 11, the bottom of the support plate 11 is welded to the top of the construction hanging basket 1 as a whole, the inner side of the detection frame 2 is inserted with a switching mechanism 3, the synchronous detection component 4 comprises an outer layer guide mechanism 5 and an inner layer detection mechanism 6, the end of the switching mechanism 3 is connected to the bottom of the outer layer guide mechanism 5 The parts are fixed as a whole, the rear end of the outer guide mechanism 5 is integrated with a guide column 15, and a push rod 25 is installed in the middle of the inner detection mechanism 6. The push rod 25 passes through the inside of the guide column 15, and the rear end of the push rod 25 is connected with a signal line 24. The side of the detection frame 2 is screwed with a voltage detector 9, and the signal line 24 is partially electrically connected to the voltage detector 9. The safety detection device for power construction is only used in the process of high-altitude construction of the exterior wall of the building, and cooperates with the hanging basket system to assist construction personnel in constructing the power facilities on the wall.

[0029] When the present invention is used, the construction workers stand directly on the construction hanging basket 1, and the construction hanging basket 1 is suspended and lifted by the lifting system on the top. In the subsequent construction process, the synchronous detection component 4 built on the construction hanging basket 1 performs voltage and current detection on the wall construction area within the moving range of the construction hanging basket 1. During construction, the synchronous detection component 4 uses the spring rod 37 at the rear end of the switching mechanism 3 to push the outer guide mechanism 5 against the wall of the power construction area, and at the same time, with the help of the booster spring 31, the inner detection mechanism 6 is synchronously pushed against the wall. At this time, the power information detected in the contacted wall area can be transmitted to the voltage detector 9 through the signal line 24 with the help of the inner detection mechanism 6, thereby achieving the purpose of detecting the power construction area. In the subsequent construction process, the construction hanging basket 1 can also drive the synchronous detection component 4 to move when it moves, and can cooperate with the switching mechanism 3 to flexibly switch the moving state of the synchronous detection component 4 according to the movement state of the construction hanging basket 1.

[0030] In this embodiment, the detection frame 2 includes an arc plate 10 and a support plate 11, a notch 12 is provided in the middle of the arc plate 10, an extension plate 8 is integrally formed on the side of the arc plate 10, and an end plate 13 is welded on the inner side of the arc plate 10. A lifting ring 7 is welded on the top of the arc plate 10, a sling 36 is connected to the top of the lifting ring 7, the shell part of the voltage detector 9 is screwed on the surface of the extension plate 8, and the detection frame 2 is installed at the two ends of the construction hanging basket 1 in a symmetrical form. Two detection frames 2 are installed on the top of the hanging basket, and each detection frame 2 is equipped with an independent synchronous detection component 4, so that during the entire construction process, the internal construction personnel do not need to manually detect the voltage or current of the wall in the construction area, and can automatically realize real-time detection, which improves the convenience of construction work and reduces the difficulty of operation in the power construction process. Among them, the voltage detector 9 is an existing mature technology and does not belong to the protection scope of the present invention, so its internal structure and principle are not described here.

[0031] Specifically, the top curved plate 10 can be supported by fixing the support plate 11 to the construction hanging basket 1. The bottom of the curved plate 10 is connected to the synchronous detection component 4 through the plug-in switching mechanism 3, and a notch 12 is also provided on the surface of the curved plate 10. Therefore, the construction personnel standing inside the construction hanging basket 1 can directly hold the handle 23 and directly control the inner detection mechanism 6 with the help of the handle 23.

[0032] In this embodiment, the switching mechanism 3 includes a motor 33 and a drive shaft 34, one end of the drive shaft 34 is plugged into the output end of the motor 33, a pull plate 21 is sleeved on the surface of the drive shaft 34, a strip hole 22 is opened on the surface of the pull plate 21, and a handle 23 is welded on one end of the pull plate 21. A support bearing 35 is sleeved on the surface of the drive shaft 34, and the drive shaft 34 is embedded in the interior of one of the end plates 13 through the support bearing 35. The housing part of the motor 33 is screwed on the surface of the other end plate 13, and the pull plate 21 is sleeved on the surface of the drive shaft 34 through the inner strip hole 22. The switching mechanism 3 can directly control the synchronous detection component 4 to rotate around the detection frame 2. Therefore, when the construction hanging basket 1 moves horizontally or vertically during the construction process, it can ensure that the outer layer guide mechanism 5 and the inner layer detection mechanism 6 are always in a state of fitting and detecting with the surface of the wall, so that the voltage detection process will not be disturbed by the movement process, and the detection range is more comprehensive.

[0033] Specifically, after starting the motor 33, the drive shaft 34 is driven to rotate by the motor 33, and the drive shaft 34 drives the fixed ring 20 and the rotating arm 19 at the end to rotate, so that the outer guide mechanism 5 can be controlled to rotate, and the central axis of the arc plate 10 coincides with the central axis of the drive shaft 34. Therefore, after starting the motor 33, the outer synchronous detection component 4 can be switched along the surface of the arc plate 10, so that the insulating roller 16 and the conductive wheel 30 can be flexibly switched between the horizontal pressing state and the vertical state. Through this structure, the insulating roller 16 and the conductive wheel 30 can be controlled to remain in a vertical state when the construction hanging basket 1 is lifted or lowered, or the insulating roller 16 and the conductive wheel 30 can be kept in a horizontal state against the wall when the construction hanging basket 1 is translated, to ensure that they can move synchronously with the construction hanging basket 1.

[0034] In this embodiment, the outer layer guide mechanism 5 includes a support frame 14 and an insulating roller 16. The rear end of the support frame 14 is integrally formed with a guide column 15. The insulating roller 16 is embedded in the inner wall end of the support frame 14 through the middle support shaft part, and the number of insulating rollers 16 is two, and a gap 17 is provided between the two insulating rollers 16. One end of the guide column 15 is integrally formed with a transmission frame 18, and the end of the transmission frame 18 is integrally formed with a rotating arm 19. The bottom of the rotating arm 19 is provided with a fixing collar 20, and the end of the driving shaft 34 is inserted with a spring rod 37.

[0035] Specifically, the insulating roller 16 is pressed against the wall. Therefore, when a small raised obstacle appears on the wall, the insulating roller 16 can be pressed on the obstacle first. At this time, the inner layer detection mechanism 6 on the inside can be driven away from the wall. As the subsequent construction hanging basket 1 continues to move, the conductive wheel 30 can be pressed on the obstacle, thereby realizing the contact detection process of various conductive devices on the wall.

[0036] In this embodiment, the inner layer detection mechanism 6 includes a push rod 25, a telescopic sleeve 29 and a conductive wheel 30. One end of the push rod 25 is connected to a signal line 24. The end of the push rod 25 is inserted into the inside of the telescopic sleeve 29. The end of the telescopic sleeve 29 is inserted with a brush 32. The conductive wheel 30 is sleeved on the surface of the brush 32. The surface of the push rod 25 is sleeved with a booster spring 31. The two ends of the booster spring 31 are respectively against the surface of the telescopic sleeve 29 and the guide column 15. The middle of the guide column 15 is interspersed with a convex column 27. One end of the convex column 27 is installed with a pressure detection module 28. The push rod 25 passes through the inside of the convex column 27. The surface of the push rod 25 is integrally formed with a pressing plate 26. The pressing plate 26 is used to press against the surface of the pressure detection module 28. The conductive wheel 30 is inserted into the gap 17 between the two insulating rollers 16. The top end of the pulling plate 21 is sleeved on the surface of the push rod 25 through a bearing. With the help of the outer guide mechanism 5 pressing on the wall and hiding the inner detection mechanism 6 inside, when a small obstacle appears on the wall during the movement of the hanging basket, the outer guide mechanism 5 can be used to pre-drive the inner detection mechanism 6 to move outward, so as to avoid the conductive wheel 30 and the brush 32 in the inner detection mechanism 6 from being hit. When encountering a larger obstacle, the construction personnel can manually pull it. When encountering a concave area, the pressure detection module 28 can be used for detection and early warning processing, so that the detection device can be applied to any situation in the construction area on the wall.

[0037] Specifically, when a large obstacle appears on the wall surface where the hanging basket moves, the handle 23 can be manually pulled to make the pulling plate 21 move along the driving shaft 34, and drive the top rod 25 to move synchronously, and finally move the conductive wheel 30 at the end away from the wall position so that it can avoid the obstacle. Further pulling the handle 23 can also synchronously drive the outer layer guide mechanism 5 to move so that it can also move away from the wall. When the construction hanging basket 1 stops, the wall area corresponding to the inner layer detection mechanism 6 is a concave structure. At this time, due to the push of the booster spring 31, the conductive wheel 30 is embedded in the inside of the groove, and the pressing plate 26 is pulled against the pressure detection module 28, and finally the pressure alarm is triggered to remind that the inner layer detection mechanism 6 is not effectively in contact with the wall of the construction area, so as to avoid the phenomenon of failure to detect in time. The pressure detection module 28 is an existing mature technology and does not belong to the protection scope of the present invention. Therefore, its internal structure and principle are not described in detail here.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
