DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1 to 7 As shown, an embodiment of the present invention is a power fault detection device, comprising: a power fault detector housing 1; a data detection display screen 2 installed in the power fault detector housing 1; a first wiring head 3 arranged on one side of the data detection display screen 2; a second wiring head 4 arranged on the other side of the data detection display screen 2; a connecting wire 5 plugged into the first wiring head 3 and the second wiring head 4; the connecting wire 5 is divided into a ground wire and a test wire, one end of the test wire is connected to the probe rod, the other end of the test wire can be plugged into the first wiring head 3, and the end of the ground wire can be plugged into the second wiring head 4;

[0034] A shield mechanism 6 is arranged on both sides of the data detection display screen 2, and a light sensor 61 is also arranged on the shield mechanism 6; and a control module connected to the shield mechanism 6 through a signal, and the shield mechanism 6 adjusts its own angle through the control module to block light from the data detection display screen 2.

[0035] Specifically, when it is necessary to perform fault detection on the power equipment, first connect the connecting line 5 to the first terminal 3 and the second terminal 4 respectively, and then scan the power equipment through the probe on the test line in the connecting line 5. During this process, the data detection display screen 2 will display the power data obtained by the scan. When the power data displayed on the data detection display screen 2 is not a normal value, it can be known that a fault has occurred at this point in the power equipment. When the staff performs fault detection on the power equipment outdoors, due to the strong outdoor light, the staff will not be able to see the data detection display screen 2 clearly, and will miss the fault point of the power equipment, resulting in inaccurate positioning of the fault point of the power equipment. At this time, the staff can start the light sensor 61 to detect the light intensity, and then adjust the angle of the shutter mechanism 6 through the control module, and use the shutter mechanism 6 to block the light on the data detection display screen 2, so that the staff can see the numerical changes on the data detection display screen 2, and then determine the fault point of the power equipment, thereby improving the accuracy of power equipment fault detection.

[0036] Please pay attention to Figures 1 to 3As shown, both sides of the power fault detector housing 1 are provided with accommodating grooves 11, and the accommodating grooves 11 are located on both sides of the data detection display screen 2; the shutter mechanism 6 is provided with two groups, which are respectively located in the accommodating grooves 11, and the shutter mechanism 6 includes: a shift rod 62 that slides in the accommodating groove 11; a support spring 63 whose two ends are respectively fixed to the shift rod 62 and the bottom wall of the accommodating groove 11; a shielding frame plate 64 rotatably connected to the shift rod 62, the light sensor 61 is arranged on the inner wall of the shielding frame plate 64, and a sliding groove 641 is provided on the outer side of the shielding frame plate 64; a top rod 65 that slides in the sliding groove 641, one end of the top rod 65 is placed in the sliding groove 641, and the other end of the top rod 65 is fixed to the end of an electric push rod 66; and an electric push rod 66 fixed to the top rod 65, and the electric push rod 66 slides laterally on the power fault detector housing 1.

[0037] Specifically, in the initial state, the two groups of shield frames are in a vertical state with the data detection display screen 2. When the angle of the shield mechanism 6 is adjusted by the control module, the control module controls the electric push rod 66 to move toward the shield frame plate 64. The movement of the electric push rod 66 drives the top rod 65 to move. The movement of the top rod 65 pushes the shield frame plate 64 to rotate on the shift rod 62, thereby blocking the light on the data detection display screen 2, making it easier for the staff to see the numerical changes on the data detection display screen 2.

[0038] Please pay attention to Figure 2 , Figure 4 As shown, it also includes a clamping mechanism 7, and the clamping mechanism 7 is provided with two groups, which are respectively located on the sides of the first terminal 3 and the second terminal 4, and the clamping mechanism 7 is used to strengthen the fixation between the connecting line 5 and the first terminal 3 and the second terminal 4; the clamping mechanism 7 includes: a first gear 71 rotatably connected to the power fault detector box 1; a first clamping plate 72 fixedly connected to the first gear 71; a second gear 73 rotatably connected to the power fault detector box 1, the first gear 71 is meshed with the second gear 73, and the second gear 73 is smaller than the first gear 71; and a second clamping plate 74 fixedly connected to the second gear 73; the shutter mechanism 6 also includes a plurality of tooth blocks 75 fixedly connected to the side of the electric push rod 66, and the tooth blocks 75 are meshed with the first gear 71.

[0039] Specifically, when the staff is performing fault detection on the power equipment, since the staff is walking with the power detection equipment, the power detection equipment will be shaken as the staff is walking, which will cause the connecting line 5 and the first terminal 3 and the second terminal 4 to become loose, thereby causing errors in the power data obtained by the probe on the test line in the connecting line 5, thereby affecting the staff's judgment on the power equipment fault at this location, resulting in inaccurate positioning of the fault point of the power equipment.

[0040] Specifically, when the control module controls the electric push rod 66 to move toward the shielding frame 64, the electric push rod 66 drives the tooth block 75 to move, and the tooth block 75 drives the first gear 71, the first clamping plate 72, the second gear 73, and the second clamping plate 74 to rotate. As the first clamping plate 72 and the second clamping plate 74 rotate continuously and approach the connecting line 5, the connecting line 5 will be clamped and fixed to prevent the connecting line 5 from loosening with the first terminal 3 and the second terminal 4 due to the staff's walking and bumping, thereby improving the accuracy of the power data obtained by the probe. At the same time, a rubber sheet is integrally provided on the first clamping plate 72 and the second clamping plate 74. The rubber sheet enhances the fixity between the first clamping plate 72, the second clamping plate 74 and the connecting line 5, and also buffers the connecting line 5, thereby preventing the connecting line 5 from excessive deformation. Through the cooperation of the shielding mechanism 6 and the clamping mechanism 7, the light can be blocked on the data detection display screen 2 while preventing the connecting line 5 from loosening with the first terminal 3 and the second terminal 4, thereby further improving the accuracy of power equipment fault detection.

[0041] Please pay attention to Figure 2 , Figure 4 , Figure 5 As shown, a pulling groove 661 is formed on the electric push rod 66; the shutter mechanism 6 also includes: a tooth tail block 76 sliding in the pulling groove 661, the tooth tail block 76 can mesh with the first gear 71; and a retaining spring 77 whose two ends are respectively fixed to the tooth tail block 76 and the side wall of the pulling groove 661.

[0042] Specifically, when the control module controls the electric push rod 66 to move toward the shielding plate 64, when the first clamping plate 72 and the second clamping plate 74 have clamped and fixed the connecting line 5, the shielding plate 64 still needs to rotate toward the direction of the data detection display screen 2 to block the light from it. At this time, the electric push rod 66 moves toward the shielding plate 64, driving the tooth block 75 and the tooth tail block 76 to move. At this time, the tooth tail block 76 will stop moving forward with the electric push rod 66 under the action of the retaining spring 77 and the first gear 71, and due to the pulling of the tooth tail block 76 by the retaining spring 77, the position of the first gear 71 and the second gear 73 will also be fixed, so that the first clamping plate 72 and the second clamping plate 74 can still fix the connecting line 5.

[0043] Specifically, the push rod 65 is a telescopic rod. When the shield frame and the data detection display screen 2 are in a vertical state and the end of the point push rod is in contact with the shield frame, the push rod 65 is in the shortest state.

[0044] Please pay attention to Figure 1 , Figure 2 , Figure 6As shown, it also includes a cover mechanism 8 arranged on the power fault detector box 1; the cover mechanism 8 includes: a box cover 81 for closing the power fault detector box 1; and a securing block 82 fixed to the inner wall of the box cover 81 for accommodating the connecting line 5.

[0045] Please pay attention to Figure 2 , Figure 6 As shown, it is characterized in that: the consolidation block 82 is provided in plurality and its position corresponds to the accommodating groove 11, and a slot 821 adapted to the shielding plate 64 is opened on the consolidation block 82; the cover mechanism 8 also includes a magnetic block 83 fixedly connected to the bottom wall of the slot 821; the shielding mechanism 6 also includes a magnetic plate 67 arranged on the top of the shielding plate 64.

[0046] Specifically, the consolidation block 82 can be used to store the connecting wire 5 in the power equipment when the power equipment is not in use to avoid the connecting wire 5 being lost, and the power fault detector case 1 and the cover mechanism 8 are closed, which is beneficial to protecting the data detection display screen 2. When the power equipment does not need to be detected, the cover mechanism 6 is reset through the control module. At this time, the connecting wire 5 is first separated from the first terminal 3 and the second terminal 4, and then the connecting wire 5 is wrapped and stored on the consolidation block 82, and then the box cover 81 and the power fault detector case 1 are closed. When closing, the consolidation block 82 presses the cover plate 64 down into the accommodating groove 11. When the box cover 81 and the power fault detector case 1 are completely closed, the magnetic block 83 and the magnetic plate 67 are adsorbed, and the connecting wire 5 can be fixed on the consolidation block 82 to avoid displacement, entanglement and knotting of the connecting wire 5.

[0047] Example 2

[0048] like Figures 1 to 7 Please pay attention to Figure 7 As shown, the control module includes: a data processing unit for determining whether to adjust the shutter mechanism 6 according to the light intensity; and a control unit for controlling the shutter mechanism 6 to adjust the angle according to the result of the data processing unit.

[0049] The control module also includes a state monitoring unit, which is used to obtain the light intensity information corresponding to the two sets of shielding plates 64 and the state information of the corresponding electric push rods 66, and transmit the light intensity information corresponding to the shielding plates 64 and the state information of the corresponding electric push rods 66 to the data processing unit;

[0050] The data processing unit determines the shielding plate 64 to be adjusted by weighted summation according to the light intensity information corresponding to the two groups of shielding plates 64 and the state information of the corresponding electric push rods 66; and sends the determined information of the shielding plate 64 to the control unit;

[0051] The regulating unit selects the corresponding shield mechanism 6 for adjustment and control according to the information of the shield plate 64 , and the regulating unit selects the corresponding electric push rod 66 for movement according to the information of the shield plate 64 , and the electric push rod 66 moves toward the direction of the shield plate 64 to drive the shield plate 64 to rotate.

[0052] The illumination intensity information corresponding to the two groups of shielding plates 64 is the illumination intensity value detected by the illumination sensor 61 on the surface of each shielding plate 64;

[0053] The state information of the electric push rod 66 includes the regulating displacement speed of the electric push rod 66 corresponding to the two sets of shielding plates 64 .

[0054] In a preferred embodiment, a control method comprises the following steps:

[0055] S1: After the user opens the cover, the status monitoring unit obtains the light intensity information corresponding to the two sets of shielding plates 64 and the status information of the corresponding electric push rods 66, and transmits the light intensity information corresponding to the shielding plates 64 and the status information of the corresponding electric push rods 66 to the data processing unit;

[0056] S2: The data processing unit comprehensively determines the shielding plate 64 to be adjusted according to the light intensity information corresponding to the two groups of shielding plates 64 and the state information of the corresponding electric push rods 66, and sends the determined information of the shielding plate 64 to the control unit;

[0057] S3: The control unit selects the corresponding shutter mechanism 6 for adjustment and control according to the information of the shutter plate 64 .

[0058] The automatic adjustment of the control module is mainly related to two factors, one is the light intensity, and the other is the control displacement speed of the electric push rod 66. The light intensity information corresponding to the two groups of shield plates 64 and the control displacement speed of the corresponding electric push rod 66 are weighted and comprehensively determined to determine the shield plate 64 to be adjusted, and then the corresponding shield mechanism 6 is selected through the control unit for adjustment and control to achieve the best display effect of the data detection display screen 2.

[0059] In order to combine the illumination intensity information corresponding to the two sets of shielding plates 64 and the state information of the corresponding electric push rods 66 by weighted summation, we have marked them as and V, and introduce two weights and to indicate their importance in the weighted sum.

[0060] The weighted sum expression can be: = × + × (i is 1 or 2)

[0061] in: Represents the light intensity information corresponding to the first group of shielding plates 64.

[0062] Represents the light intensity information corresponding to the second group of shielding plates 64.

[0063] Represents the control displacement speed corresponding to the first group of electric push rods 66.

[0064] Represents the control displacement speed corresponding to the second group of electric push rods 66.

[0065] is the weight of the light intensity information corresponding to the shielding plate 64.

[0066] is the weight corresponding to the state information of the electric push rod 66.

[0067] In practical applications, the weight and The choice of should be based on the specific application scenario and requirements to ensure that they can accurately reflect the relative importance in the scenario. At the same time, the sum of these two weights should usually be equal to 1 (or 100%, if expressed as a percentage) to indicate that they together constitute the total weight of the entire weighted sum.

[0068] Light intensity information corresponding to the two sets of shielding plates 64: When the staff conducts outdoor power equipment inspection, since the light intensity is different at different times and locations, the light intensity values ​​detected by the light sensors on the surfaces of the two sets of shielding plates 64 are also different. Therefore, the staff needs to adjust the best shielding plates 64 for adjustment.

[0069] Corresponding to the status information of the electric push rods 66: the status monitoring unit can obtain the past usage data of the electric push rods 66 to determine which group of electric push rods 66 has a faster control displacement speed.

[0070] The state monitoring unit transmits the light intensity information corresponding to the two sets of shielding plates 64 and the state information of the corresponding electric push rod 66 to the data processing unit, and the data processing unit substitutes the relevant information into × + × In the data processing unit, the comparison , The size of the first set of shielding plates 64 or the second set of shielding plates 64 to be adjusted is determined. > At this time, adjusting the first set of shielding plates 64 can allow the staff to see the power data on the data detection display screen more quickly. < At this time, adjusting the second set of shielding plates 64 can allow the staff to see the power data on the data detection display screen more quickly. After the data processing unit comprehensively determines the shielding plate 64 to be adjusted, the determined shielding plate 64 information is sent to the control unit, and then the control unit selects the corresponding shielding mechanism 6 for adjustment and control according to the shielding plate 64 information, and finally can quickly adjust the corresponding shielding mechanism 6 to the optimal state, so that the staff can see the power data on the data detection display screen.
