[0042] The technical solution of the present application provides a method for collecting battery power by a battery power collection device, comprising the following steps:

[0043] S1. After the current transformer and the data acquisition terminal are assembled into a whole through the connection mechanism, the assembled whole structure is installed and fixed at a preset position through the mounting bracket on the current transformer;

[0044] S2. Pass the conductive cables of the battery to be tested through the current transformer and a pair of locking pieces located at the open ends of the current transformer, and adjust the acquisition terminal to a suitable angle through the universal unit;

[0045] S3, closing the two insulating half-clamps in the locking member;

[0046] S4, during the closing process of the insulating half-clamp, the thermally conductive elastic structure applies an elastic clamping force to the elastic side wall of the guide cable of the battery, and the shrinking thermally conductive elastic structure simultaneously increases the damping value of the universal unit;

[0047] S5. After the insulating half-clamps in the two pairs of locking members are closed and connected together, the conductive cable is clamped and fixed while passing through the part inside the current transformer. At the same time, the damping value of the universal unit reaches the preset value and the acquisition terminal is positioned and locked after the angle is adjusted;

[0048] S6. The current transformer converts the large current passing through the conductive cable into a small current. The acquisition terminal then acquires the small current output by the current transformer. The acquisition terminal then transmits the acquired data to the external main controller. The external main controller processes and analyzes the acquired current data to calculate the battery power.

[0049] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. The collection terminal and the current transformer are combined and installed together through a connecting mechanism to form an integral device. When the combined integral device is installed, the angle of the collection terminal can be flexibly adjusted through the universal unit, which is convenient for operators to install the device in a narrow installation environment. In addition, in the subsequent process of the locking member clamping and fixing the conductive cable of the battery to be tested in the current transformer, the locking member can also reversely increase the damping value of the universal unit and position and lock the collection terminal after adjusting the angle. In this way, not only can the device be quickly installed on the conductive cable of the battery to be tested and the parameters of the battery during operation can be monitored and collected, but also only the combined integral device needs to be inspected and repaired during subsequent maintenance, which reduces the difficulty and cost of maintenance, improves maintenance efficiency, and can greatly reduce the occurrence of damage to the device caused during maintenance.

[0050] 2. Before the locking piece clamps and fixes the conductive cable, the non-retracted thermally conductive elastic structure will not squeeze the insulating coolant into the hemispherical chamber, so that the spherically distributed elastic resistance-increasing diaphragm will not elastically expand and be pressed tightly against the surface of the steering sphere in the universal unit. When the universal unit is in the initial state, the damping value is small. When the installation direction or angle of the acquisition terminal needs to be adjusted, the smaller damping value can provide greater flexibility and save effort, and it is also convenient for the device to be installed in a narrow installation scene.

[0051] 3. The retracted thermally conductive elastic structure causes the spherically distributed elastic resistance-increasing diaphragm to expand elastically and press tightly against the surface of the steering ball in the universal unit, greatly increasing the friction force that needs to be overcome for the steering ball to rotate. As a result, while the locking member clamps the conductive cable, the locking member can also reversely increase the damping value of the universal unit and position and lock the acquisition terminal after angle adjustment, which is convenient for the special installation requirements of the battery power acquisition device and can also increase the distance between the current transformer and the acquisition terminal, helping to reduce electromagnetic interference between the two and improve the accuracy and reliability of the data collected by the acquisition device.

[0052] 4. Two pairs of locking pieces clamp and fix the conductive cable passing through the part inside the current transformer. The fixation of the conductive cable reduces the electromagnetic interference caused by the movement or vibration of the cable during the detection process of the current transformer, which helps to improve the accuracy and stability of the current transformer measurement data, thereby improving the accuracy of the battery operation data collection results. In addition, the heat energy generated by the cable when working is continuously transferred to the insulating coolant through the thermal conductive elastic structure, and then the insulating coolant continuously absorbs the heat energy to achieve cooling and heat dissipation of the cable, avoiding the high fever caused by the heat unable to dissipate in time due to the blocking of the clamped part of the conductive cable, thereby extending the service life of the battery whose parameters are to be collected, and also helping to improve the safety of the battery power parameter collection work.

[0053] 5. When the locking parts are closed and connected together, the distance sensor in the hydraulic sensing structure will be triggered to open. The distance sensor will then detect the distance between its detection end and the baffle plate and transmit the detection signal to the control panel. When the distance value detected by the distance sensor is within the preset value range of the control panel, it will be convenient for the operator to judge whether the hydraulic pressure acting on the surface of the elastic resistance-increasing diaphragm is sufficient after the locking parts are closed, thereby indirectly judging whether the damping force in the universal unit reaches the preset level after the locking parts are closed and connected, thereby ensuring the positioning and locking effect of the acquisition terminal after the angle adjustment.

[0054] 6. During the long-term use of this collection device, when the insulating heat-conducting clamp rod fails to seal due to aging of the seal on it, the insulating coolant leaks, and the distance between the baffle plate and the detection end of the distance sensor increases and exceeds the preset critical value of the control panel, at this time, the control panel controls the anti-loosening implementation member to block the part connecting the liquid storage cavity and the diversion hose, and also triggers the alarm to turn on, which is convenient for the staff to troubleshoot, so that the device can monitor the damping value in the universal unit in real time when performing the collection task, and take timely sealing and pressure-maintaining measures when the universal unit leaks.

[0055] 7. After the anti-slip implementation piece blocks the input end of the guide hose, when the operator observes through the display screen on the control panel that the distance value detected by the distance sensor further decreases, it can be determined that the seal between the connecting rod and the column hole has failed to seal, which makes it easier for the staff to accurately find the fault point.

A control unit is provided on the side wall of the insulating base 307. The insulating base 307 has damping members and anti-slip members arranged up and down inside.

[0079] The acquisition terminal 20 and the current transformer 10 are combined and installed together through the connecting mechanism to form an integral device. When the combined integral device is installed, the angle of the acquisition terminal 20 can be flexibly adjusted through the universal unit in the connecting mechanism, which is convenient for operators to install the device in a narrow installation environment. In addition, in the subsequent process of clamping and fixing the conductive cable of the battery to be tested in the current transformer 10 through the locking member on the connecting mechanism, the locking member can also reversely increase the damping value of the universal unit to position and lock the acquisition terminal 20 after adjusting the angle. In this way, not only can the device be quickly installed at the conductive cable of the battery to be tested and the parameters of the battery during operation can be monitored, but also only the combined integral device needs to be inspected during subsequent maintenance, which reduces the difficulty and cost of maintenance, improves maintenance efficiency, and can greatly reduce the occurrence of device damage caused during maintenance.

[0081] The two end frames are respectively fixedly mounted on the side walls of the two hoop frames 306;

[0083] After the two clamping frames 306 are sleeved on the current transformer 10 , the two clamping frames 306 are connected together, so as to facilitate the fixing and installation of the clamping member on the current transformer 10 .

[0084] Reference Figures 1 to 5 The embodiment of the present application provides a battery power collection device, wherein the thermally conductive elastic structure includes an insulating thermally conductive clamping rod 301 that is sealed and slides in a retreat groove. A sealing member is pre-installed on the insulating thermally conductive clamping rod 301, and the insulating thermally conductive clamping rod 301 is sealed and slides in the retreat groove through the sealing member. The insulating thermally conductive clamping rod 301 is made of a thermally conductive insulating material.

[0085] A return spring is connected to one end of the insulating heat-conducting clamp rod 301 extending into the retraction groove, and the other end of the return spring is connected to the inner wall of the arc-shaped cavity connected to the retraction groove;

[0087] The excitation spring 328 is connected to the end of the corresponding insulating heat-conducting clamp rod 301, and the excitation terminal 312 is connected to the inner wall of the arc-shaped cavity connected to the retreat groove;

[0088] The retreat groove, the arc-shaped cavity and the guide hose 303 are all filled with insulating coolant 313 .

[0089] Reference Figure 6 and Figure 8 , the embodiment of the present application provides a battery power collection device, the damping member includes a hydraulic sensing component, a distance sensor 323 and a plurality of elastic resistance-increasing diaphragms 319 distributed in a spherical surface, and the distance sensor 323 is preferably an infrared distance sensor;

[0090] The hydraulic sensing component includes an elastic sensing diaphragm 320, and a passive guide rod 321 is connected to the elastic sensing diaphragm 320;

[0091] A shielding plate 322 that cooperates with the distance sensor 323 is connected to the side wall of the passive guiding rod 321 .

[0092] Reference Figures 6 to 8 A hemispherical chamber 317 is provided inside the insulating base 307 and is located below the hemispherical groove. The hemispherical chamber 317 is a chamber in a hemispherical shape.

[0093] The elastic resistance-increasing diaphragm 319 is located inside the insulating base 307 and between the hemispherical chamber 317 and the hemispherical groove. The inner wall of the hemispherical groove is provided with a spring opening connected to the hemispherical chamber 317 corresponding to the position of each elastic resistance-increasing diaphragm 319, and each elastic resistance-increasing diaphragm 319 is connected to the corresponding spring opening.

[0094] The insulating base 307 is provided with a same-pressure side groove in communication with the hemispherical chamber 317, and a guide groove is provided at the end of the same-pressure side groove;

[0095] The elastic sensing diaphragm 320 is connected to the same pressure side groove, and the passive guide rod 321 is slidably inserted into the guide groove at one end away from the elastic sensing diaphragm 320. When the elastic sensing diaphragm 320 is in the initial relaxation state, the end of the passive guide rod 321 is located in the guide groove;

[0096] The hemispherical chamber 317 and the isobaric side groove are filled with insulating coolant 313;

[0097] The distance sensor 323 is connected to the side wall of the insulating base 307 , and the detection end of the distance sensor 323 extends into the same-pressure side groove and faces the shielding plate 322 .

[0098] Before the locking piece clamps and fixes the conductive cable passing through the current transformer 10, the non-retracted thermally conductive elastic structure on the insulating half-clamp 302 will not squeeze the insulating coolant 313 into the hemispherical chamber 317, so that the spherically distributed elastic resistance-increasing diaphragm 319 will not elastically expand and be pressed tightly against the surface of the steering sphere 305 in the universal unit. When the universal unit is in the initial state, the damping value is smaller. The smaller damping value allows the acquisition terminal 20 to drive the universal unit to rotate more freely. When the installation direction or angle of the acquisition terminal 20 needs to be adjusted, the smaller damping value can provide greater flexibility and save effort, and it is also convenient for the device to be installed in a narrow installation scene.

[0099] The retracted thermally conductive elastic structure squeezes the insulating coolant 313 into the interior of the hemispherical chamber 317, causing the spherically distributed elastic resistance-increasing diaphragm 319 to expand elastically and press tightly against the surface of the steering sphere 305 in the universal unit, greatly increasing the friction force that needs to be overcome for the steering sphere 305 to rotate. As a result, while the locking member clamps and fixes the conductive cable of the battery to be tested in the current transformer 10, the locking member can also reversely increase the damping value of the universal unit and position and lock the acquisition terminal 20 after the angle adjustment, which is convenient for the special installation requirements of the battery power acquisition device and can also increase the distance between the current transformer 10 and the acquisition terminal 20, thereby helping to reduce electromagnetic interference between the two and improving the accuracy and reliability of the data collected by the acquisition device.

[0100] After the insulating half-clamps 302 in the two pairs of locking pieces at the open ends of the current transformer 10 are closed and connected together, the conductive cable is clamped and fixed while passing through the internal part of the current transformer 10. At the same time, the damping value of the universal unit reaches the preset value and the acquisition terminal 20 is positioned and locked after the angle is adjusted. The fixation of the conductive cable reduces the electromagnetic interference caused by the movement or vibration of the cable during the detection process of the current transformer 10, which helps to improve the accuracy and stability of the measurement data of the current transformer 10, thereby improving the accuracy of the battery operation data acquisition results. In addition, the current When the mutual inductor 10 is detecting the conductive cable passing through it, the heat energy generated by the cable when it is working is continuously transferred to the insulating coolant 313 located in the retreat groove through the thermally conductive elastic structure, and then the insulating coolant 313 continuously absorbs the heat energy. The heat energy absorbed by the insulating coolant 313 is then dissipated into the air, thereby cooling and dissipating the cable, avoiding the high fever caused by the heat unable to be dissipated in time due to the blocking of the clamped part of the conductive cable, thereby extending the service life of the battery whose parameters are to be collected, and also helping to improve the safety of the battery power parameter collection work.

[0101] After the locking pieces are closed and connected together, the hydraulic pressure acting on the inner wall surfaces of the elastic sensing diaphragm 320 and the elastic resistance-increasing diaphragm 319 increases and causes the elastic resistance-increasing diaphragm 319 and the elastic sensing diaphragm 320 to deform elastically outwardly. The deformed elastic resistance-increasing diaphragm 319 is tightly attached to the surface of the steering ball 305 to restrict the steering ball 305 from rotating. The deformed elastic sensing diaphragm 320 drives the shielding plate 322 to move toward the distance sensor 323. When the locking pieces are closed and connected together, the thermally conductive elastic structure drives the trigger spring 328 to contact the trigger terminal 312 and trigger The distance sensor 323 in the hydraulic sensing structure is turned on, and then the distance sensor 323 detects the distance between its detection end and the baffle plate 322 and then transmits the detection signal to the control panel 308. When the distance value detected by the distance sensor 323 is within the preset value range of the control panel 308, it is convenient for the operator to judge whether the hydraulic pressure acting on the surface of the elastic resistance-increasing diaphragm 319 is sufficient after the locking member is closed, thereby indirectly judging whether the damping force in the universal unit reaches the preset level after the locking member is closed and connected, thereby ensuring the positioning and locking effect of the acquisition terminal 20 after the angle adjustment.

[0103] A spherical groove matching the steering ball 305 is provided at the inner end of the upper cover 304 corresponding to the position of the circular hole;

[0104] The steering ball 305 is connected to a steering drive arm 310, and the steering drive arm 310 passes through the circular hole on the upper cover 304 and is detachably connected to the collection terminal 20;

[0105] The control unit includes a battery box connected to the side wall of the insulating base 307, a battery is arranged in the battery box, and a control panel 308 is also connected to the battery box;

[0106] When the upper cover 304 is covered and connected to the end of the insulating base 307, the steering ball 305 rotates in the space limited by the hemispherical groove and the spherical groove.

[0107] Reference Figure 6 , Figure 7 , Fig.10 and Fig.11 , the embodiment of the present application provides a battery power collection device, the anti-slip implementation member includes an alarm 327, a switch movable terminal 325 and a switch static spring piece 326 arranged opposite to each other, and two blocking blocks 315, wherein the alarm 327 is a wireless alarm;

[0108] The two plugging blocks 315 are arranged symmetrically.

[0109] One of the blocking blocks 315 is connected to a driving frame 316, and the other blocking block 315 is connected to a driven frame 314. A transmission gear 324 is provided between the driving frame 316 and the driven frame 314.

[0110] A tooth groove meshing with the transmission gear 324 is provided between the opposing surfaces of the active frame 316 and the driven frame 314;

[0111] A connecting rod 318 is connected to one end of the active frame 316, an electric telescopic rod 309 is connected to the other end of the connecting rod 318, and a bracket is connected to the electric telescopic rod 309;

[0112] The switch moving terminal 325 and the switch static spring piece 326 are both located on the side of the active frame 316 away from the connecting rod 318;

[0113] The insulating base 307 is provided with a liquid storage cavity located below the hemispherical chamber 317 and connected to the hemispherical chamber 317, and the transmission gear 324 is rotatably connected to the liquid storage cavity;

[0114] The two guiding hoses 303 on the locking member are respectively connected to the left and right sides of the insulating base 307 and communicate with the liquid storage cavity, and the liquid storage cavity is filled with insulating coolant 313;

[0115] The two plugging blocks 315 are slid left and right on the bottom wall of the liquid storage cavity, and the opposite ends of the two plugging blocks 315 are respectively oriented toward the input ends of the guide hose 303 located on the left and right sides of the insulating base 307;

[0116] The switch moving terminal 325 is connected to the side wall of the active frame 316, the switch static spring 326 is connected to the side wall of the liquid storage cavity, and the alarm 327 is connected to the side wall of the insulating base 307;

[0117] A column hole connected to the liquid storage cavity is provided on the side wall of the insulating base 307, and the end of the connecting rod 318 away from the active frame 316 is sealed and passed through the column hole and connected to the electric telescopic rod 309. In this article, the gap between the column hole and the connecting rod 318 is sealed by a seal pre-installed in the column hole, so that the connecting rod 318 can pass through the column hole in a sealed manner. The seal in this article is a common material or part such as a sealing ring that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from invading the components inside the machine equipment;

[0118] The electric telescopic rod 309 is located outside the insulating base 307 , and one end of the bracket away from the electric telescopic rod 309 is connected to the side wall of the insulating base 307 .

[0119] During the long-term use of the collection device, when the insulating heat-conducting clamp rod 301 that is sealed and slides in the retreat groove fails to seal due to the aging of the seal on the sealing member, the insulating heat-conducting clamp rod 301 causes leakage of the insulating coolant 313, causing the hydraulic pressure acting on the surface of the elastic resistance-increasing diaphragm 319 and the elastic sensing diaphragm 320 to drop, so that the distance between the shielding plate 322 and the detection end of the distance sensor 323 increases and exceeds the preset critical value of the control panel 308. At this time, the control panel 308 controls the electric telescopic rod 309 in the anti-slip implementation member to extend a specific length, and the active frame 316 that moves synchronously with the extended electric telescopic rod 309 drives the driven frame 314 to move through the transmission gear 324, so that the two blocking blocks 315 move in opposite directions and connect the liquid storage cavity with the diversion hose 303. While the connected parts are blocked, the movable active frame 316 also drives the switch moving terminal 325 to contact the switch static spring piece 326 to trigger the alarm 327 to send an alarm signal to the external main controller, which is convenient for the staff to check the fault and avoid further leakage. When the device is performing the acquisition task, it can monitor the damping value in the universal unit in real time, and take timely sealing and pressure maintenance measures when the universal unit leaks, so as to ensure that the damping value of the universal unit is within the appropriate range, thereby effectively preventing the universal unit from continuously decreasing and becoming unstable due to sealing failure during the acquisition task of the acquisition device, thereby causing the distance between the current transformer 10 and the acquisition terminal 20 to become closer, so that the two generate mutual electromagnetic interference, resulting in a decrease in the accuracy and reliability of the collected data.

[0120] After the anti-slip implementation component blocks the input end of the diversion hose 303, when the operator observes through the display screen on the control panel 308 that the distance value detected by the distance sensor 323 further decreases, it can be determined that the seal between the connecting rod 318 and the column hole has failed, which makes it convenient for the staff to accurately find the fault point.

[0121] The control panel 308 , the electric telescopic rod 309 and the distance sensor 323 are powered by the battery in the battery box of the control unit. After the distance sensor 323 transmits the detection signal to the control panel 308 , the operator can view the detection value of the distance sensor 323 through the display screen on the control panel 308 .

[0122] The present application embodiment provides a method for collecting battery power collection devices, comprising the following steps:

[0123] S1. After the current transformer 10 and the data acquisition terminal 20 are assembled into a whole through the connection mechanism, the assembled whole structure is installed and fixed at a preset position through the mounting bracket on the current transformer 10;

[0124] S2, pass the conductive cables of the battery to be tested through the current transformer 10 and a pair of locking pieces respectively located at the open ends of the current transformer 10, and adjust the acquisition terminal 20 to a suitable angle through the universal unit;

[0125] S3, closing the two insulating half-clamps 302 in the locking member;

[0126] S4, during the closing process of the insulating half-clamp 302, the thermally conductive elastic structure applies an elastic clamping force to the elastic side wall of the guide cable of the battery, and the retracted thermally conductive elastic structure simultaneously increases the damping value of the universal unit;

[0127] S5. After the insulating half-clamps 302 in the two pairs of locking members are closed and connected together, the conductive cable is clamped and fixed while passing through the inner part of the current transformer 10. At the same time, the damping value of the universal unit reaches the preset value and the acquisition terminal 20 is positioned and locked after the angle is adjusted;

[0128] S6. The current transformer 10 converts the large current passing through the conductive cable into a small current. The acquisition terminal 20 then acquires the small current output by the current transformer. The acquisition terminal 20 then transmits the acquired data to the external main controller. The external main controller processes and analyzes the acquired current data to calculate the battery power.

[0129] The external main controller mentioned in this article is a computer or other common existing technology that plays a control role, and the detachable connection methods mentioned in this article include but are not limited to: bolt connection and snap connection.
