It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

In order to solve the problem that the partial discharge detection device is inflexible and cannot be safely operated in the prior art, the application provides a partial discharge detection device and a patrol car.

In the present application, the inspection vehicle has a partial discharge detection device described below.

Optionally, the partial discharge detection device may be disposed on a roof of the inspection vehicle, so that the partial discharge detection device is convenient to detect the circuit to be detected.

As shown in fig. 1 to 9, the partial discharge detection device in the present application includes a conveying mechanism 10, a detection device 30 and a driving structure 40, wherein the conveying mechanism 10 is pivotally disposed on a base body and has an extended working position and a standby recovery position; the detection device 30 is movably arranged on the conveying mechanism 10 and has a working position and a stopping position; the driving mechanism 40 is drivingly connected to the conveying mechanism 10, and when the conveying mechanism 10 is switched from the standby recovery position to the extended working position, the detecting device 30 moves from the stop position to the working position, and when the conveying mechanism 10 is switched from the standby recovery position to the extended working position, the detecting device 30 moves from the working position to the stop position.

When the partial discharge detection device with the above structure is used, the detection device 30 is mounted on the conveying mechanism 10, so that when the partial discharge detection of the circuit is required, the driving mechanism 40 drives the conveying mechanism 10, the detection device 30 can be adjusted from the stop position to the working position, and the circuit required to be detected is further detected. Since the conveyor 10 can be adjusted from the standby retracted position to the extended working position while the detection device 30 is adjusted from the stop position to the working position, the partial discharge detection device can not only have a large detection distance during working, but also occupy less space during standby. In addition, in the whole process of detecting the circuit, detection workers do not need to approach the circuit to be detected. Therefore, the utility model discloses solved the inflexible and unable safe problem of operation of partial discharge detection device effectively.

In particular, as shown in fig. 3 to 5, the detection device 30 moves in translation along the transport mechanism 10. Because the detection device 30 is arranged on the conveying mechanism 10, the installation difficulty of the detection device 30 can be reduced through the arrangement, and when the translation moving mode is selected to switch the detection device 30 between the working position and the stop position, the stable movement of the detection device 30 can be ensured, so that the stable operation of the whole partial discharge detection device can be effectively ensured.

Specifically, as shown in fig. 6, the conveying mechanism 10 includes a conveying mount 11, driving and driven wheels 12 and 13, and a conveying belt 14. The driving wheel 12 and the driven wheel 13 are respectively and fixedly arranged at two ends of the transmission fixing frame 11; the conveying belt 14 sequentially passes through the driving wheel 12 and the driven wheel 13, the detection device 30 is arranged on the conveying belt 14, the driving structure 40 drives the driving wheel 12 to rotate, so that the driving wheel 12 drives the conveying fixing frame 11 to move between the extending operation position and the standby recovery position, and simultaneously, the driving wheel 12 drives the conveying belt 14 to move so as to drive the detection device 30 to switch between the working position and the stop position. By this arrangement, in the process of driving the conveying mechanism 10 by using the driving structure 40, not only the conveying mechanism 10 can be switched between the extended working position and the standby recovery position, but also the driving wheel 12 can be driven to rotate, so that the driving wheel 12 drives the conveying belt 14 and the driven wheel 13 to rotate, and the detecting device 30 can be switched between the working position and the stop position.

In the embodiment shown in fig. 1 to 5, the mounting position of the detection device 30 is the right side of the driven wheel 13. It should be noted that the mounting position of the detection device 30 may also be the left side of the driven wheel 13. Further, the position of the detection device 30 can be selected according to the actual usage.

Specifically, as shown in fig. 7 to 9, when the detection device 30 is moved to the position of the driven wheel 13, the detection device 30 reaches the working position; when the detecting device 30 moves from the working position to the stopping position, the detecting device 30 moves to a direction gradually approaching the driving wheel 12, and the distance between the working position and the stopping position is smaller than the distance between the driven wheel 13 and the driving wheel 12. By such an arrangement, it can be ensured that the detection device 30 moves only between the driving wheel 12 and the driven wheel 13, and does not pass through the driving wheel 12 or the driven wheel 13, thereby ensuring that the detection device 30 performs one-side movement of the conveying mechanism.

Optionally, the distance between the working position and the rest position is 50 cm to 80 cm. Of course, the distance between the operating position and the rest position may be set in other ranges as long as the normal operating requirements are met.

Optionally, the conveying mechanism 10 further includes two synchronizing wheels 15 disposed at intervals and a synchronizing belt 16 passing around the synchronizing wheels 15, one synchronizing wheel 15 is disposed coaxially with the driving wheel 12 and rotates synchronously, and the driving mechanism 40 drives the synchronizing wheel 15 to drive the driving wheel 12 to rotate. Through the arrangement, the sizes of the driving wheel 12 and the driven wheel 13 of the conveying mechanism can be optimized by setting the transmission ratio of the reasonable synchronizing wheel 15, so that the structure of the whole partial discharge detection device can be more compact, and the manufacturing cost of the conveying mechanism 10 is reduced. Moreover, the transfer mechanism can be maintained conveniently by the arrangement.

Alternatively, the transmission ratio of two spaced synchronizing wheels 15 is 1:10, and the synchronizing wheel 15 with larger diameter is connected with the driving wheel 12 of the conveying mechanism through a fixed shaft 70. Of course, the transmission ratio of the two synchronizing wheels 15 can also be other values, as long as a reasonable design is ensured, i.e. when the transfer mechanism 10 is in the extended working position, the detection device 30 can be in the working position; and when the conveyance mechanism 10 is in the standby recovery position, the detection device 30 can be in the stop position.

Optionally, the partial discharge detection apparatus further includes a base 50, the base 50 has a cavity and a yielding notch 52 communicated with the cavity, the synchronizing wheel 15, the synchronizing belt 16 and the driving structure 40 are all located in the cavity, and one end of the driving wheel 12 and one end of the transmission fixing frame 11 are located at the yielding notch 52. Since the environment in which the partial discharge detection device is used is generally severe, the synchronizing wheel 15, the timing belt 16, and the driving structure 40 can be installed inside the base 50 by such an arrangement, thereby preventing the synchronizing wheel 15, the timing belt 16, and the driving structure 40 from being exposed to the outside.

Optionally, the transmission mount 11 comprises two oppositely disposed lateral panels 111 to form a space therebetween for accommodating the transmission belt 14, the driving wheel 12 and the driven wheel 13, the lateral panels 111 being perpendicular to the axis of the driving wheel 12; a protective panel 112, the protective panel 112 extending around the periphery of the conveyor belt 14 and an opening 113 being reserved between both ends of the protective panel 112 for the detection device 30 to move at the opening 113. By this arrangement, the conveyor belt 14 can be covered by the lateral panels 111 and the protective panels 112, so that it is possible to prevent foreign objects from entering the conveyor belt 14 to jam the conveyor belt 14. But also ensures that the detecting device 30 moves at one side of the conveyor belt 14, and controls the moving stroke of the detecting device 30.

Specifically, when the detection device 30 is in the working position, the transfer mechanism 10 is deployed into the horizontal plane to reach the extended working position; when the detection device 30 moves from the working position to the stop position, the conveying mechanism 10 is unfolded with the substrate as a base point of rotation so as to gradually increase an included angle with a horizontal plane.

Specifically, the angle of the conveyance mechanism 10 between the projecting work position and the standby retracted position is 90 degrees or more and 180 degrees or less.

By such an arrangement, the space occupied by the partial discharge detection device can be effectively reduced. And when partial discharge detection device installs at the car top of patrolling and examining, can accomodate at the car top of patrolling and examining when partial discharge detection device is out of work.

As shown in fig. 8, the partial discharge detection apparatus further includes a connection frame 80, the connection frame 80 is a multi-fold plate-shaped structure, one end of the connection frame 80 is fixed to the conveyor 14, and the other end of the connection frame 80 is fixed to the detection apparatus 30. And the multi-fold plate-like structure provides an installation space for the sensing device 30.

As shown in fig. 1, the partial discharge detector further includes a connection bracket 20, and the base 50 is fixed on the base body through the connection bracket 20. When the base is a roof, the attachment bracket 20 is fixed to the roof. Specifically, the connecting angle bracket 20 has a T-shaped structure, but other shapes meeting the installation requirement are also possible and are not limited to the shape shown in the drawings.

Specifically, the partial discharge detection apparatus further includes an angular velocity detection element 60, wherein the angular velocity detection element 60 is configured to detect an actual angular velocity of the driving structure 40, and feed back the actual angular velocity to the driving structure 40 when the actual angular velocity reaches a preset angular velocity, and the driving structure 40 stops operating. By such arrangement, the working position and the stop position of the detection device 30, the standby recovery position and the extending working position of the conveying mechanism 10 can be limited, and the detection device 30 can be aligned to the position to be detected of the circuit to be detected when the circuit to be detected is detected by using the partial discharge detection device.

Alternatively, the angular velocity detecting member 60 is fixed to the mounting panels 51 on both sides of the base 50. In fig. 6, there are three mounting panels 51, wherein two of the left and right mounting panels 51 are used to form a cavity, and the angular velocity detecting member 60 is disposed between the two mounting panels 51 on the same side, so that the mounting panels 51 protect the angular velocity detecting member 60.
