Description

Technical Field

[0001] The present invention relates to the technical field related to detection devices, and in particular to a high-voltage cable accessory test detection device. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, and power cable accessories are products that connect cables to transmission and distribution lines and related distribution equipment. In order to ensure the safety of cables when they are put into use, partial discharge detection operations need to be performed on the cables and their accessories during their production process to prevent voltage instability, leakage and other phenomena. Therefore, partial discharge detection equipment is needed.

[0003] At present, the high-voltage cable accessory test and detection devices on the market are large in size and not easy to carry, so they have limitations on the detection range and distance of the cables. In related technologies, by setting a telescopic mechanism and a mobile mechanism, the high-voltage cable accessory test and detection device is convenient to carry while increasing the scope of application. However, in actual use, it is only in contact with the ground through the moving wheels, which reduces its stability and is prone to position displacement, thereby affecting normal detection and causing inconvenience to use. Summary of the Invention

[0004] The object of the present invention is to provide a high-voltage cable accessory test and detection device to solve the problems raised in the above background technology.

[0005] The technical solution adopted in the present invention is:

[0006] A high-voltage cable accessory test and detection device, comprising:

[0007] The box body has a display screen on its side;

[0008] A multi-section telescopic electric cylinder is arranged in the box;

[0009] An adjusting mechanism is installed at the output end of the multi-section telescopic electric cylinder;

[0010] A clamping plate is provided on the adjusting mechanism, and the adjusting mechanism is used to adjust the position of the clamping plate;

[0011] A current detection sensor is fixedly connected to the side of the clamping plate;

[0012] A base, fixedly connected to the bottom of the box;

[0013] A telescopic rod, fixedly connected to the bottom of the base;

[0014] a damping spring shock absorber, disposed in the telescopic rod;

[0015] A moving wheel is installed at the bottom end of the telescopic rod;

[0016] An electric push rod, fixedly connected to the inner side of the base;

[0017] The pad is slidably connected in the base and tightly abuts against the output end of the electric push rod.

[0018] Optionally, the telescopic rod, the damping spring shock absorber and the moving wheel are a group, and multiple groups are arranged at the bottom of the base.

[0019] Optionally, a slide rail is provided on the base;

[0020] a housing, slidably connected to the outer side of the slide rail;

[0021] A fixing bolt is threadedly connected to the housing, and one end of the fixing bolt is tightly pressed against the slide rail.

[0022] Optionally, the slide rail has a T-shaped cross section.

[0023] Optionally, a connecting plate is fixedly connected to the side of the cushion block, a groove is provided on the base, and the slide rail passes through the groove and is fixedly connected to the connecting plate.

[0024] Optionally, the connecting plate is located at the center of the side of the pad.

[0025] Optionally, the height of the pad is greater than the height of the display screen.

[0026] Optionally, a blocking cover is rotatably connected to both the box body and the shell.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The high-voltage cable accessory test and detection device realizes intelligent detection through the coordinated use of an intelligent display screen, a multi-section telescopic electric cylinder, an adjustment mechanism, a clamping plate and a current detection sensor. Before performing the detection operation, the device moves via moving wheels. During the movement, the device performs a shock-absorbing operation by squeezing a damping spring shock absorber, thereby protecting the equipment on the box. The electric push rod is turned on before the detection so that the pad supports the base, thereby ensuring stability during subsequent detection. This solves the problem that the existing high-voltage cable accessory test and detection device does not have a good adjustment function. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the products of the present invention are conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] Given that the current existing technology has large specifications for the detection device and is not easy to carry, the detection range and distance of the cable are limited. In the related technology, by setting a telescopic mechanism and a mobile mechanism, the high-voltage cable accessory test detection device is convenient to carry while increasing the scope of application. However, in actual use, it is only in contact with the ground through the moving wheels, which reduces its stability and is prone to position displacement, thereby affecting normal detection and causing inconvenience to use.

[0042] like Figure 1-4 As shown, an embodiment of the present invention provides a high-voltage cable accessory test and detection device, including: a box body 10, a display screen 11 is provided on the side of which; a multi-section telescopic electric cylinder 12 is arranged in the box body 10; an adjusting mechanism 13 is installed at the output end of the multi-section telescopic electric cylinder 12; a clamping plate 14 is arranged on the adjusting mechanism 13, and the adjusting mechanism 13 is used to adjust the position of the clamping plate 14; a current detection sensor 15 is fixedly connected to the side of the clamping plate 14; a base 20 is fixedly connected to the bottom of the box body 10; a telescopic rod 21 is fixedly connected to the bottom of the base 20; a damping spring shock absorber 22 is arranged in the telescopic rod 21; a moving wheel 23 is installed at the bottom end of the telescopic rod 21; an electric push rod 24 is fixedly connected to the inner side of the base 20; a pad 25 is slidably connected in the base 20 and is tightly pressed against the output end of the electric push rod 24.

[0043] Before performing the detection operation, directly push the box 10 to move it through the moving wheel 23. During the movement, squeeze the telescopic rod 21 and the damping spring shock absorber 22 inside the telescopic rod 21 to achieve movement while performing a shock-absorbing operation to protect the equipment on the box 10. After moving to the specified position, the multi-section telescopic electric cylinder 12 is turned on by operating the display screen 11, so that the output end of the multi-section telescopic electric cylinder 12 pushes the adjustment mechanism 13 to rise, so that the adjustment mechanism 13 moves to the cable and cable accessories. During the adjustment process, it can still push the box 10 to fine-tune the position. Then turn on the electric push rod 24, so that its output end pushes the pad 25 to slide out from under the base 20, and support the base 20 and the box 10 to ensure stability during subsequent testing. Finally, turn on the adjustment mechanism 13, adjust the position of the splint 14, so that the splint 14 clamps the cable, and detects it through the current detection sensor 15. After the detection is completed, repeat the above steps in reverse to achieve storage, which is convenient for subsequent transportation and carrying.

[0044] Specifically, the adjustment mechanism 13 is composed of a motor, a screw and a slider. By turning on the motor, the screw rotates, and then the slider is threadedly connected to the screw, so that the slider moves and drives the splint 14 to move, thereby realizing the adjustment of the position of the splint 14. This belongs to the existing technology, so it will not be described in detail.

[0045] Specifically, the model of the multi-section telescopic electric cylinder 12 is RLD163, which belongs to the existing technology and will not be described in detail.

[0046] Specifically, a power supply is provided in the box 10, and the driver of the multi-section telescopic electric cylinder 12 is matched with the power supply. The display screen 11 communicates with the driver through RS485, Ethernet and other interfaces to ensure normal parameter settings and instruction transmission. These are all existing technologies, so they will not be elaborated on.

[0047] Furthermore, the telescopic rod 21, the damping spring shock absorber 22 and the moving wheel 23 are a group, and multiple groups are provided at the bottom of the base 20 so that multiple moving wheels 23 work simultaneously to ensure stability during movement.

[0048] Furthermore, the slide rail 30 is provided on the base 20 ; the housing 31 is slidably connected to the outside of the slide rail 30 ; the fastening bolt 32 is threadedly connected to the housing 31 , and one end of the fastening bolt 32 is tightly pressed against the slide rail 30 .

[0049] When the display screen 11 does not need to be operated, the fixing bolt 32 is rotated to disengage one end thereof from the slide rail 30 , and the housing 31 is directly pushed upward to slide the housing 31 upward on the slide rail 30 until the housing 31 covers the display screen 11 , thereby providing a covering and protective effect for the display screen 11 .

[0050] Furthermore, the cross section of the slide rail 30 is T-shaped to prevent the housing 31 from separating from the slide rail 30 .

[0051] Furthermore, a connecting plate 40 is fixedly connected to the side of the cushion block 25 , a groove 41 is formed on the base 20 , and the slide rail 30 passes through the groove 41 and is fixedly connected to the connecting plate 40 .

[0052] Turn on the electric push rod 24, so that the pad 25 slides out from the bottom of the base 20, and pull the connecting plate 40, so that the connecting plate 40 pulls the slide rail 30 and the shell 31 to slide downward at the same time, and finally the pad 25 supports the base 20 while leaking out the display screen 11, thereby facilitating the operation of the staff.

[0053] Specifically, a control switch is provided on the side of the box body 10 for controlling the opening and closing of the electric push rod 24 .

[0054] Furthermore, the connecting plate 40 is located at the center of the side of the cushion block 25, so that the connecting plate 40 can slide up and down more stably.

[0055] Furthermore, the height of the cushion block 25 is greater than that of the display screen 11 , so that when the cushion block 25 props up the base 20 , the display screen 11 can be completely exposed, or when the cushion block 25 is stored, the housing 31 can completely cover the display screen 11 .

[0056] Furthermore, both the box body 10 and the shell 31 are rotatably connected with a blocking cover to improve the dust-proof effect.

[0057] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
