Description

Technical Field

[0001] The present invention relates to the technical field of charging equipment, and in particular to an automatic charging device for a self-propelled insulation testing vehicle and an operating method thereof. Background Art

[0002] The significance of 6KV switchgear insulation testing is to ensure the safe and stable operation of the power plant power system, prevent electrical fires, improve the reliability of important motor equipment in the power plant, and save energy. Insulation testing monitors and diagnoses the insulation status of electrical equipment, promptly discovers insulation defects in the equipment, and takes corresponding measures to avoid equipment failure, thereby ensuring the safe and stable operation of the power plant power system.

[0003] The insulation test of 6KV switch cabinet has two modes: online monitoring and offline testing. Currently, most power plants use the offline testing mode. When testing the insulation of 6KV switch cabinet, the operator is usually required to wear insulating gloves and send the probe to the contact part. This operation mode has a certain risk of high-voltage electric shock. Therefore, the use of self-propelled insulation testing vehicles for 6KV switch cabinet insulation testing has become a new insulation testing tool for power plants. Since the battery capacity of the insulation testing vehicle is large and a relatively fast charger is required, the charging contacts are relatively thick, and the alignment and clamping of the charging device are somewhat difficult. Summary of the invention

Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] Therefore, the purpose of the present invention is to provide an automatic charging device for a self-propelled insulation testing vehicle and an operating method thereof, which solves the problem of contact clamping stability and improves the control stability of contact detection.

[0010] An elastic clamping charging assembly is mounted on the horizontal slide and driven by the horizontal slide to move along the axial direction;

[0011] The elastic clamping charging mechanism comprises an outer shell, a telescopic driving component symmetrically arranged on the side of the outer shell and extending vertically into the interior thereof, an elastic charging contact assembly mounted on the telescopic driving component, and a pressing assembly;

[0012] Among them, the elastic charging contact assembly is connected to the charging power supply through a charging cable.

[0013] As a preferred solution of the automatic charging device of a self-propelled insulation inspection vehicle described in the present invention, the telescopic slide includes a first guide seat, a first drive motor installed at one end of the first guide seat, a first drive screw coaxially connected to the output end of the first drive motor and extending to the other end of the first guide seat, and a first sliding seat connected to the first drive screw and capable of being driven by the first drive screw to move along the first guide seat.

[0016] The elastic charging contact assembly is vertically mounted on the fixed portion, and the pressing assembly is vertically mounted on the telescopic portion;

[0017] The elastic charging contact assembly includes a fixed side plate, an elastic component with one end perpendicularly arranged to the fixed side plate, a movable plate perpendicularly connected to the other end of the elastic component, and a flexible clamping ring mounted on the movable plate and connected to the charging power source through a charging cable;

[0018] Among them, in the free state, the head and tail of the flexible clamping ring are separated, and the inner diameter of the clamping ring is larger than the charging contact of the charging head. When the telescopic driving component drives the pressing assembly to squeeze the flexible clamping ring, the head and tail of the flexible clamping ring are combined to tightly wrap the charging contact of the charging head.

[0019] As a preferred solution of the automatic charging device for a self-propelled insulation testing vehicle described in the present invention, the telescopic driving component is an electric telescopic rod.

[0024] Wherein, the diameter of the socket is larger than the charging contact of the charging head and smaller than the diameter of the telescopic protective sleeve of the charging head.

[0026] S1, the horizontal slide moves, driving the elastic clamping charging assembly to move along the axis direction, and the horizontal slide stops when the magnetic induction sensor is triggered to confirm that the detection socket is aligned with the charging head;

[0027] S2, the telescopic slide moves, driving the horizontal slide to move along the axial direction, so that the automatic charging device of the self-propelled insulation testing vehicle slides outward as a whole. At this time, the charging contacts of the charging head pass through the socket and enter the flexible clamp ring, and due to the obstruction of the socket, the telescopic protective sleeve of the charging head shrinks and remains outside the outer shell;

[0028] S3. When the charging contact of the charging head enters into the flexible clamping ring, the telescopic driving component drives its telescopic part to drive the pressing assembly to move toward the direction close to the elastic charging contact assembly, so that the pressing clamping ring wraps the pressing flexible clamping ring, and then the flexible clamping ring is combined head to tail, tightly wrapping the charging contact of the charging head, and completing the connection of the charging contact.

[0029] Compared with the prior art, the present invention has the following beneficial effects: the present invention adopts electrical structure and elastic mechanical structure design, so that the elastic charging contact assembly cooperates with the pressing assembly to tightly clamp the charging contact of the self-propelled insulation inspection vehicle, thereby achieving safe and reliable charging.

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] The present invention provides an automatic charging device for a self-propelled insulation testing vehicle and an operating method thereof, which solves the problem of contact clamping stability and improves the control stability of contact testing.

[0041] Example 1

[0042] Figure 1-Figure 6 The structure diagram of the automatic charging device of a self-propelled insulation testing vehicle of the present invention is shown in FIG. Figure 1-Figure 6 In this embodiment, an automatic charging device for a self-propelled insulation testing vehicle includes a telescopic slide 100, a horizontal slide 200 and an elastic clamping charging assembly 300.

[0043] The telescopic slide 100 is used to move the automatic charging device of the self-propelled insulation inspection vehicle forward as a whole, so that the automatic charging device of the self-propelled insulation inspection vehicle can be docked with the charging head 400, and the charging head 400 can be inserted into the elastic clamping charging assembly 300 for charging. Specifically, in this embodiment, the telescopic slide 100 includes a first guide seat 110, a first drive motor 120 installed at one end of the first guide seat 110, a first drive screw 130 coaxially connected to the output end of the first drive motor 120 and extending through the other end of the first guide seat 110, and a first sliding seat 140 connected to the first drive screw 130 and can be driven by the first drive screw 130 to rotate and move along the first guide seat 110. During specific use, the first drive motor 120 drives the first drive screw 130 to rotate, driving the first sliding seat 140 to follow the first drive screw 130, driving the horizontal slide 200 installed thereon to move forward and backward, and then driving the elastic clamping charging assembly 300 to move forward and backward.

[0044] The horizontal slide 200 is installed on the telescopic slide 100 and is driven by the telescopic slide 100 to move along the Y-axis direction. In this embodiment, the horizontal slide 200 is used to drive the elastic clamping charging component 300 to move along the X-axis direction, and adjust the horizontal position of the elastic clamping charging component 300 so that the charging head 400 can be aligned with the elastic clamping charging mechanism 300. Specifically, in this embodiment, the horizontal slide 200 includes a second guide seat 210, a second drive motor 220 installed at one end of the second guide seat 210, and a second drive motor 220 connected to the second guide seat 210. The output end of the motor 220 is coaxially connected to and passes through the second driving screw 230 at the other end of the second guide seat 210, and is connected to the second driving screw 230, and can be rotated by the second driving screw 230 to drive the second sliding seat 240 to move along the second guide seat 210. During specific use, the second driving motor 220 drives the second driving screw 230 to rotate, driving the second sliding seat 240 to follow the movement of the second driving screw 230, and driving the elastic clamping charging assembly 300 installed thereon to move left and right and align with the charging head 400.

[0045] The elastic clamping charging mechanism 300 includes an outer shell 310, a telescopic driving component 320 symmetrically arranged on the side of the outer shell 310 and extending vertically into the interior thereof, an elastic charging contact assembly 330 installed on the telescopic driving component 320, and a pressing assembly 340. During specific use, the elastic charging contact assembly 330 is connected to the charging power supply through a charging line. When the charging head 400 of the self-propelled insulation inspection vehicle is inserted into the elastic charging contact assembly 330, the telescopic driving component 320 drives the pressing assembly 340 to press the elastic charging contact assembly 330, so that the elastic charging contact assembly 330 is in close contact with the charging head 400 for charging.

[0046] Example 2

[0047] See also Figure 1-Figure 6 In this embodiment, a socket 310a coaxial with the flexible clamp 330d and a magnetic induction sensor for detecting whether the socket 310a is aligned with the charging head 400 are formed on the front side wall of the outer shell 310, wherein the diameter of the socket 310a is larger than the charging contact 410 of the charging head 400 and smaller than the diameter of the telescopic protective sleeve 420 of the charging head 400, so that when the charging contact 410 passes through the socket 310a and is inserted into the elastic charging contact assembly 330, the telescopic protective sleeve 420 can be blocked by the socket 310a outside the outer shell 310, and fit with the outer shell 310 to form a protective structure for the charging contact 410, so that the charging contact 410 will not be exposed to the outside, resulting in the risk of leakage.

[0048] The telescopic driving component 320 has a fixed portion 320 a and a telescopic portion 320 b , and preferably, the telescopic driving component 320 is an electric telescopic rod.

[0049] The elastic charging contact assembly 330 is vertically mounted on the fixed portion 320a, and the pressing assembly 340 is vertically mounted on the telescopic portion 320b. The elastic charging contact assembly 330 includes a fixed side plate 330a, an elastic component 330b with one end vertically arranged on the fixed side plate 330a, a movable plate 330c vertically connected to the other end of the elastic component 330b, and a flexible clamp 330d mounted on the movable plate 330c and connected to the charging power source through a charging cable. The elastic component 330b is a spring, wherein in a free state, the flexible clamp 330d is The head and tail of the clamping ring 330d are separated, and the inner diameter of the clamping ring 330d is larger than the charging contact 410 of the charging head 400, which facilitates the charging contact 410 of the charging head 400 to be inserted into the flexible clamping ring 330d. When the telescopic driving component 320 drives the pressing assembly 340 to squeeze the flexible clamping ring 330d, the flexible clamping ring 330d is squeezed by the pressing assembly 340 from the tail separation state to the head and tail combined state, forming a complete circular ring shape, tightly wrapping the charging contact 410 of the charging head 400, and completing the charging docking with the charging contact 410 of the charging head 400.

[0050] The pressing assembly 340 includes a sliding plate 340a installed on the telescopic part 320b, and the inner wall of the sliding plate 340a is provided with a semicircular pressing ring 340b with the same height as the flexible snap ring 330d. The inner diameter of the pressing ring 340b is equal to the outer diameter of the flexible snap ring 330d, so that when the pressing ring 340b presses against the flexible snap ring 330d, the pressing ring 340b can make the flexible snap ring 330d completely docked from head to tail without any deviation.

[0051] Combination Figure 1-Figure 6 , the automatic charging device of a self-propelled insulation detection vehicle in this embodiment has the following specific operation steps:

[0052] S1, the horizontal slide 200 moves, driving the elastic clamping charging assembly 300 to move along the X-axis direction, and the horizontal slide 200 stops moving when the magnetic induction sensor is triggered to confirm that the detection socket 310a is aligned with the charging head 400;

[0053] S2, the telescopic slide 100 moves, driving the horizontal slide 200 to move along the Y-axis direction, so that the automatic charging device of the self-propelled insulation testing vehicle slides outward as a whole. At this time, the charging contact 410 of the charging head 400 passes through the socket 310a and enters the flexible clamp ring 330d, and due to the obstruction of the socket 310a, the telescopic protective sleeve 420 of the charging head 400 shrinks and remains outside the outer shell 310;

[0054] S3. When the charging contact 410 of the charging head 400 enters into the flexible clamping ring 330d, the telescopic driving component 320 drives its telescopic part 320b to drive the pressing assembly 340 to move toward the direction close to the elastic charging contact assembly 330, so that the pressing clamping ring 340b wraps the pressing flexible clamping ring 330d, and then the flexible clamping ring 330d is combined head to tail, tightly wrapping the charging contact 410 of the charging head 400, and completing the connection of the charging contact 410.

[0055] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
