[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] As described in the background art, when there are too many circuits in the meter cabinet currently, it is very inconvenient for the staff to detect the positive and negative poles of the circuits.

[0045] To solve this technical problem, the present invention provides a portable debugging device for power equipment, which is applied to power debugging.

[0046] Specifically, please refer to Figures 1-14 , the portable debugging device for power equipment specifically includes a meter body 1, two wiring harnesses 2 connected to the meter body 1, and two probes 3 respectively connected to the wiring harnesses 2, and further includes:

[0047] A folding plate 4, rotatably arranged on the meter body 1;

[0048] ​The hollow box 5 is rotatably arranged on the folding plate 4, and both wire harnesses 2 are arranged inside the hollow box 5;

[0049] The fixed seat 6 is arranged on the hollow box 5;

[0050] There are multiple suction nozzles 7, all of which are slidably arranged on the fixed seat 6;

[0051] The pressure component 8 is arranged on the hollow box 5 and is connected to the suction nozzle 7. When the meter body 1 is pulled outwards to make the folding plate 4 rotate, the pressure component 8 is used to drive the suction nozzle 7 to generate negative pressure;

[0052] The winding and unwinding component 12 is arranged on the hollow box 5 and is connected to the wire harness 2 and the pressure component 8. When the suction nozzle 7 generates negative pressure, the winding and unwinding component 12 is used to drive the two wire harnesses 2 to be released from the hollow box 5.

[0053] The portable debugging device for power equipment provided by the present invention positions a probe on the positive and negative electrodes of the electric meter through the cooperation of the pressure component, the winding and unwinding component, the first combination plate and the second combination plate. The user only needs to align the probe with the positive and negative electrodes of the remaining circuits one by one with one hand to perform detection, improving the work efficiency. The meter body can rotate to adjust the angle, which is convenient for the user to observe and collect the detected data, and the wire harness is released and wound, which is convenient for the user to carry and does not affect the detection due to the too long wire harness during use.

[0054] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0055] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0056] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0057] Example 1, please refer to Figures 9-14 , a portable debugging device for power equipment, the pressure component 8 of which includes a first spring 81 arranged outside the suction nozzle 7. The first spring 81 is arranged on the corresponding surfaces of the suction nozzle 7 and the fixed seat 6. The first spring 81 adjusts the position of the suction nozzle 7 so that the suction nozzle 7 automatically adapts to the uneven surface and performs adsorption. A driving member 9 for driving the suction nozzle 7 to generate negative pressure is arranged on the hollow box 5.

[0058] The driving member 9 includes a rotating shaft 91 rotatably arranged on the hollow box 5. The folding plate 4 is arranged on the rotating shaft 91. A cylinder 92 is arranged inside the hollow box 5. A piston 93 is slidably arranged inside the cylinder 92. A connecting pipe 94 is fixedly penetrated between the cylinder 92 and the fixed seat 6. The connecting pipe 94 is connected to a plurality of suction nozzles 7. A storage roller 95 is arranged on the rotating shaft 91. A first thin rope 96 is wound around the storage roller 95. When the storage roller 95 rotates, the first thin rope 96 pulls the piston 93 to make the suction nozzles 7 generate negative pressure through the connecting pipe 94. A guiding block 97 is arranged inside the hollow box 5. The guiding block 97 guides the first thin rope 96 during sliding to prevent the piston 93 from shifting during sliding. The first thin rope 96 is slidably arranged on the guiding block 97. One end of the first thin rope 96 is wound around the storage roller 95, and the other end of the first thin rope 96 is arranged on the piston 93. A pressure relief member 10 for releasing the negative pressure inside the suction nozzles 7 is arranged on the hollow box 5 and the watch body 1.

[0059] The pressure relief member 10 includes a one-way valve 101 arranged on the connecting pipe 94. A branch pipe 102 is arranged inside the hollow box 5. The branch pipe 102 is fixedly penetrated on the connecting pipe 94. A pressure relief valve 103 is arranged on the branch pipe 102. The two ports of the branch pipe 102 are respectively arranged on both sides of the one-way valve 101, and the pipes communicated with the two ports are only communicated with the pressure relief valve 103. When the piston 93 slides, the suction nozzles 7 generate negative pressure. When the piston 93 moves in the opposite direction, due to the one-way valve 101, the suction nozzles 7 will not generate positive pressure, preventing the suction nozzles 7 from falling during operation. The pressure relief valve 103 can connect the negative pressure generated by the cylinder 92 and the suction nozzles 7 with the external atmospheric pressure. A top column 104 is arranged on the watch body 1. The top column 104 cooperates with the pressure relief valve 103. When the watch body 1 is in the initial state, the top column 104 presses the pressure relief valve 103, so that the pressure relief valve 103 is always in a pressure relief state, and thus no negative pressure will be generated inside the suction nozzles 7 and the cylinder 92. A clamping member 11 for clamping the rotating shaft 91 during rotation is arranged on the hollow box 5.

[0060] The clamping member 11 includes an elastic block 111 arranged on the rotating shaft 91. An arc-shaped groove 112 is arranged on the hollow box 5. The elastic block 111 is slidably arranged on the arc-shaped groove 112. When the folding plate 4 and the rotating shaft 91 rotate simultaneously, the elastic block 111 on the rotating shaft 91 presses the arc-shaped groove 112. Therefore, the larger the rotation angle of the rotating shaft 91, the greater the rotation friction, preventing the situation that when the cylinder 92 generates negative pressure, the negative pressure pulls the first thin rope 96 and causes the folding plate 4 to reset.

[0061] Embodiment 2 further optimizes the portable debugging device for power equipment provided in Embodiment 1. Specifically, as Figure 11 、 Figure 13 、 Figure 14As shown, the winding component 12 includes a winding drum 121 arranged in the hollow box 5. A hollow column 122 is arranged on the winding drum 121, and the wire harness 2 is wound around the hollow column 122. A feeding and discharging disc 123 is rotatably arranged at the bottom of the winding drum 121. Discharging holes 124 are arranged on the feeding and discharging disc 123, and the wire harness 2 is slidably arranged on the discharging holes 124. When the wire harness 2 connected to one end of the probe 3 is pulled at the central part of the feeding and discharging disc 123, the feeding and discharging disc 123 rotates, and the wire harness 2 wound around the hollow column 122 will be discharged along the discharging holes 124. In this way, pulling out the wire harness 2 will not affect the wire harness 2 connected to one end of the meter body 1, preventing the wire harness 2 at one end of the meter body 1 from falling off when the wire harness 2 at one end of the probe 3 is pulled. An adjusting rod 125 is slidably arranged in the hollow box 5. A second spring 126 is connected between the adjusting rod 125 and the corresponding surface of the hollow box 5. The wire harness 2 is slidably arranged on the adjusting rod 125. When the wire harness 2 at one end of the meter body 1 is pulled, the adjusting rod 125 will be pulled. When the adjusting rod 125 slides, the second spring 126 will be compressed. When the pulling force disappears, the elastic force of the second spring 126 drives the adjusting rod 125 to reset, and then the wire harness 2 at one end of the meter body 1 returns to its original state. In this way, it prevents accidentally pulling the wire harness 2 at one end of the meter body 1, resulting in the disconnection of the wire harness 2 at one end of the meter body 1 from the meter body 1. A central hole 127 is arranged on the hollow box 5. The central hole 127 is coaxial with the hollow column 122. The wire harness 2 is slidably arranged on the central hole 127. The wire harness 2 at one end of the probe 3 is guided through the central hole 127, so that the wire harness 2 at one end of the probe 3 slides along the axis of the hollow column 122. A winding member 13 for driving the feeding and discharging disc 123 to wind the wire harness 2 around the hollow column 122 is arranged on the hollow box 5.

[0062] The winding member 13 includes a rotating shaft 131 rotatably arranged on the hollow column 122. The rotating shaft 131 is connected to the feeding and discharging disc 123. A synchronous roller 132 is arranged on the rotating shaft 131. The rotating shaft 131 is connected to the winding drum 121 through a torsion spring. A second thin rope 133 is wound around the outside of the synchronous roller 132. One end of the second thin rope 133 is connected to the meter body 1, and the other end of the second thin rope 133 is wound around the synchronous roller 132. When the meter body 1 is pulled and unfolded, the second thin rope 133 pulls the synchronous roller 132, and the synchronous roller 132 and the rotating shaft 131 rotate synchronously, and then the feeding and discharging disc 123 rotates synchronously, so that the wire harness 2 outside the hollow column 122 is released. A guiding member 14 for guiding the wire harness 2 during winding is arranged in the winding drum 121.

[0063] The guiding member 14 includes a guiding post 141 disposed on the access and exit tray 123. An adjusting ring 142 is slidably disposed on the guiding post 141. The adjusting ring 142 is slidably disposed on the hollow column 122. A guiding hole 143 is provided on the adjusting ring 142. The wire harness 2 is slidably disposed on the guiding hole 143. Threads are provided on the inner wall of the take-up reel 121. The adjusting ring 142 is threadedly connected to the take-up reel 121. When the access and exit tray 123 rotates, the guiding post 141 rotates synchronously. The guiding post 141 drives the adjusting ring 142 to rotate and displace along the inner wall of the take-up reel 121. While the adjusting ring 142 rotates and displaces, the wire harness 2 is wound around the hollow column 122 through the guiding hole 143, guiding the wire harness 2 during winding and unwinding, and preventing the wire harness 2 from stacking or winding together inside the take-up reel 121.

[0064] Embodiment 3 further optimizes the portable debugging device for power equipment provided in Embodiment 1 or 2. Specifically, as Figures 1-7 shown, elastic clamping blocks 15 are provided on the hollow box 5 to limit the probe 3 through the elastic clamping blocks 15, facilitating the fixation of the probe 3 to the hollow box 5. A clamping seat 16 is provided on the outer side of the meter body 1. A mating block 18 is slidably disposed on the clamping seat 16. Threads are provided on the outer sides of both the mating block 18 and the probe 3. Clamping blocks 17 are slidably disposed on both sides of the clamping seat 16. A first combined plate 19 and a second combined plate 20 are respectively rotatably disposed at both ends of the two clamping blocks 17. A third spring 23 is connected to the corresponding surfaces of the two clamping blocks 17. When the threads on the surface of the probe 3 cooperate with the mating block 18, the probe 3 can displace up and down on the mating block 18. The meter is clamped by the clamping blocks 17, enabling the probe 3 to be fixed on the meter. Then, the mating block 18 is slid and adjusted to position the probe 3 on the positive and negative electrodes of the circuit. In this way, the staff can use another probe 3 to successively test other positive and negative electrodes, reducing the work intensity of the staff. When the first combined plate 19 and the second combined plate 20 rotate 180 degrees and unfold, the area of the meter clamped by the clamping blocks 17 will increase, preventing the probe 3 positioned outside the meter from falling off. When the first combined plate 19 and the second combined plate 20 rotate 90 degrees and unfold, as Figure 1 shown, the meter body 1 and the hollow box 5 cooperate, facilitating the staff to carry and protecting the display screen on the meter body 1 from being damaged by external extrusion. When the first combined plate 19 and the second combined plate 20 are stacked together, the first combined plate 19, the second combined plate 20 and the clamping blocks 17 form a wedge-shaped block, facilitating the clamping of the meter.

[0065] An L-shaped groove 21 is provided on the hollow box 5. A clamping block 22 is provided on the clamping seat 16. The L-shaped groove 21 and the clamping block 22 cooperate with each other, as Figure 6As shown, when there is too much dust in the meter cabinet and the suction nozzle 7 cannot work, the L-shaped groove 21 is engaged with the clamping block 22, so that the first combined plate 19, the second combined plate 20 and the clamping block 17 are fixed on the hollow box 5, which facilitates the fixing of the meter body 1 on the meter cabinet.

[0066] The usage process of the portable debugging device for power equipment provided by the present invention is as follows:

[0067] When in use, the suction nozzle 7 is attached to the inner wall of the meter cabinet, and then the meter body 1 is pulled outwards. The meter body 1 drives the folding plate 4 to rotate, and the rotating shaft 91 on the folding plate 4 rotates synchronously. The elastic block 111 on the rotating shaft 91 squeezes the arc-shaped groove 112, increasing the friction force of the rotation of the rotating shaft 91. The storage roller 95 on the rotating shaft 91 rotates synchronously, and the storage roller 95 winds up the first thin rope 96. The first thin rope 96 slides along the guiding block 97 and pulls the piston 93, so that the piston 93 slides along the cylinder body 92. Through the connecting pipe 94, a negative pressure is generated between the suction nozzle 7 and the inner wall of the meter cabinet, so that the suction nozzle 7 together with the hollow box 5 and the meter body 1 are all fixed on the inner wall of the meter cabinet. When the meter body 1 is pulled outwards, the second thin rope 133 is pulled by the meter body 1. The second thin rope 133 drives the rotating shaft 131 to rotate, and the access plate 123 on the rotating shaft 131 rotates synchronously. The access plate 123 drives the guiding column 141 to rotate synchronously. The guiding column 141 drives the adjusting ring 142 to rotate. The adjusting ring 142 rotates and displaces along the winding cylinder 121. The guiding hole 143 on the adjusting ring 142 drives the wire harness 2 not to wind around the hollow column 122. When one end of the probe 3 is pulled out, the wire harness 2 is synchronously pulled out, and the positive and negative poles of the circuit are detected by the two probes 3;

[0068] Through the thread matching between the outside of the probe 3 and the thread on the matching block 18, the probe 3 is fixed on the matching block 18. Then, the position of the probe 3 on the matching block 18 is adjusted by the thread. Then, the meter is clamped by the clamping block 17, so that the probe 3 is fixed on the meter. Then, the matching block 18 is slid and adjusted, so that the probe 3 is positioned on the positive and negative poles of the circuit. In this way, the staff only needs to successively test other positive and negative poles with the other probe 3;

[0069] When there is too much dust in the meter cabinet and the suction nozzle 7 cannot work, the L-shaped groove 21 is engaged with the clamping block 22, so that the first combined plate 19, the second combined plate 20 and the clamping block 17 are fixed on the hollow box 5, which facilitates the fixing of the meter body 1 on the meter cabinet;

[0070] When the meter body 1 returns to the initial state, the jacking column 104 squeezes the pressure relief valve 103. The pressure relief valve 103 drives the pressure in the cylinder body 92 and the suction nozzle 7 to communicate with the external atmospheric pressure, so that the suction nozzle 7 releases the adsorption on the meter cabinet.
