Description

Technical Field

[0001] The present application relates to the technical field of mining machinery, and in particular to a mining cage charging device, a control method and a mining cage system. Background Art

[0002] In mining operations, cages are essential tools for transporting materials and personnel in and out of mines. With the advancement of intelligent mines, cages are becoming increasingly complex, with the addition of lighting, cameras, automatic curtain doors, and automatic vehicle arresters. The proper operation of these devices requires a stable and continuous power supply.

[0003] Traditional cage power supply methods typically rely on external power supply systems, connecting cage equipment to the mine grid via cables or using battery packs. However, due to the complex mine environment, cables are susceptible to wear, moisture, and corrosion. Furthermore, battery packs have a limited power supply time, making it difficult to maintain the long-term operation of power-intensive equipment such as automatic tank curtain doors and automatic vehicle arresters.

[0004] In related technologies, wireless charging is used to power cages within mines. For example, wireless charging devices are installed at the cage's docking points to achieve wireless charging. However, as the cage ages, it becomes difficult to consistently dock at the correct charging location, resulting in reduced wireless charging efficiency and even failure to charge.

DETAILED DESCRIPTION

The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0030] In mining production, cages play an important role. Cages are usually suspended in the shaft by steel wire ropes. However, after a long period of operation, the steel wire ropes may become loose, which makes it impossible for the cage to accurately stop at the predetermined position, resulting in a decrease in the charging efficiency of the wireless charging device for charging the cage's battery, or even failure to charge. The embodiment of the present application provides a cage charging device for mining, which can achieve stable and reliable charging of the battery in the cage. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 Schematic diagram of the composition structure of the mining cage charging equipment provided in this application, Figure 2 This is a schematic diagram of the structure of the wireless charging device in the mining cage charging equipment provided in this application. Figure 3 This is a schematic diagram of the structure of the cage in the mining cage charging equipment provided in this application. Figure 4 This is a schematic diagram of the structure of the adjustment device in the mining cage charging equipment provided in this application.

[0031] The cage charging device provided in the embodiment of the present application includes: a wireless charging device 1, an adjustment device 2, and a detection device 3. The wireless charging device 1 includes a transmitter 11 and a receiver 12, wherein the receiver 12 is configured to be disposed on the cage 4; the adjustment device 2 is configured to be disposed on the shaft 5 in which the cage 4 operates, and the transmitter 11 is disposed on the adjustment device 2, which is capable of driving the transmitter 11 to move relative to the receiver 12; the detection device 3 is configured to be disposed between the cage 4 and the shaft 5 and electrically connected to the adjustment device 2. The detection device 3 is configured to detect the relative position of the receiver 12 and the transmitter 11 and is configured to send a first control signal to the adjustment device 2 based on a detected detection signal.

[0032] In this embodiment of the present application, wireless charging can be used to provide power to the battery 42 in the cage 4 to charge the battery 42 on the cage 4. For example, the battery 42 in the cage 4 can be a secondary battery 42 (a battery 42 that can be charged and discharged multiple times), thereby powering the devices in the cage 4 through the secondary battery 42. A wireless charging device 1 that matches the cage 4 can be provided. For example, the receiving unit 12 of the wireless charging device 1 can be provided on the cage 4, and the transmitting unit 11 of the wireless charging device 1 can be provided at the location on the shaft 5 where the cage 4 is docked. Then, when the cage 4 is docked in the shaft 5, the battery 42 in the cage 4 can be charged by the wireless charging device 1.

[0033] For example, Figure 2 As shown, the transmitter 11 can be configured to include a transmitter host 111 and a transmitter coil 112. The transmitter host 111 can be electrically connected to a power supply 6 outside the wellbore 5 (on the surface) to provide power to the transmitter 11. The transmitter host 111 can be configured to have adjustable output power. Indicator lights can also be provided in the transmitter 11, for example, red, yellow, and green. When the red indicator light is constantly on, it indicates normal charging; when the yellow indicator light is constantly on, it indicates that the charging power is outside a preset power threshold range; and when the green indicator light is constantly on, it indicates that the cage battery is fully charged.

[0034] In another example, the receiving unit 12 may be configured to include a receiving host 121 and a receiving coil 122. Figure 3 As shown, the receiving host 121 and the receiving coil 122 can both be fixed to the cage upper plate 41 of the cage 4, and the receiving host 121 can be electrically connected to the battery 42 of the cage 4. The receiving host 121 can be configured to adjust voltage and / or current, so that the power generated by the receiving coil 122 can be stabilized by receiving proximity, so that the voltage and current transmitted to the battery 42 meet the charging requirements of the battery 42. When the receiving unit 12 and the transmitting unit 11 are installed, the distance between the transmitting coil 112 and the receiving coil 122 can be 40 mm to 80 mm.

[0035] In the embodiment of this application, Figure 1 As shown, a movable adjustment device 2 may be provided. The adjustment device 2 may be disposed on the shaft 5, for example, at an upper wellhead of the shaft 5 close to the ground, and located adjacent to the motion path of a receiving portion 12 disposed on the cage 4. The transmitting portion 11 may be disposed on the adjustment device 2, for example, by fixing the transmitting coil 112 in the transmitting portion 11 to a movable component on the adjustment device 2.

[0036] For example, the adjustment device 2 can be a device capable of generating linear motion, such as a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or a linear motor. The adjustment device 2 can drive the transmitter 11 to move relative to the receiver 12 along the axis Z (vertical direction or a direction substantially parallel to the vertical direction) of the wellbore 5.

[0037] In the embodiment of the present application, a detection device 3 may be provided to detect the relative position of the receiving unit 12 with respect to the transmitting unit 11, thereby determining whether the receiving unit 12 is within a suitable charging area relative to the transmitting unit 11. For example, the detection device 3 may be one or more of a travel switch, a photoelectric sensor, an electromagnetic sensor, a capacitive sensor, and a Hall sensor.

[0038] For example, a portion of the detection device 3 may be disposed on the cage 4, and another portion of the detection device 3 may be disposed on the wall of the shaft 5. Alternatively, another portion of the detection device 3 may be disposed on a movable component of the adjustment device 2. In this way, as the cage 4 is raised or lowered within the shaft 5, the detection device 3 can be used to determine whether the cage 4 is in the correct docking position, and thus whether the receiving unit 12 is within the appropriate charging area relative to the transmitting unit 11.

[0039] As another example, the detection device 3 can be electrically connected to the adjustment device 2. In this way, when the detection device 3 detects that the receiving part 12 is outside the charging area relative to the transmitting part 11, the detection device 3 can send a first control signal to the adjustment device 2. The adjustment device 2 generates a movement of the transmitting part 11 along the axial direction Z of the wellbore 5 in response to the received first control signal until the transmitting part 11 moves to the receiving part 12 within the charging area.

[0040] The mining cage charging device provided in the embodiment of the present application is provided with a wireless charging device 1, which can charge the battery 42 in the cage 4 through the wireless charging device 1, thereby reducing the impact of wear and corrosion on the cage 4 power supply caused by the cable powering the cage 4. Furthermore, an adjustment device 2 is provided, and the transmitter 11 is mounted on the adjustment device 2. In the event that the cage 4 cannot drive the receiving unit 12 to stop relative to the transmitter 11 within the charging area due to looseness of the wire rope, the adjustment device 2 can drive the transmitter 11 to move, thereby placing the receiving unit 12 within the charging area of the transmitter 11. Furthermore, a detection device 3 is provided for detecting the relative position of the receiving unit 12 and the transmitter 11, and the detection device 3 is electrically connected to the adjustment device 2. The detection device 3 can accurately determine the relative position of the transmitter 11 and the receiver 12, thereby improving the accuracy of the adjustment device 2 in driving the transmitter 11 to move relative to the receiver 12. In this way, the receiving part 12 can be placed in the charging area of the transmitting part 11 in a timely manner through the adjustment device 2 and the detection device 3. Therefore, the mining cage charging equipment provided in the embodiment of the present application can realize stable and reliable charging of the battery 42 in the cage 4.

[0041] In some possible embodiments of the present application, Figure 4 As shown, the adjustment device 2 includes a fixed portion 21 and a movable portion 22 . The fixed portion 21 is used to be installed on the wellbore 5 . The movable portion 22 is movably connected to the fixed portion 21 . The transmitting portion 11 is arranged on the movable portion 22 .

[0042] In an embodiment of the present application, a matching fixed part 21 and a moving part 22 can be set in the adjustment device 2, and the moving part 22 can be configured as a structure capable of moving relative to the fixed part 21, so as to drive the transmitting part 11 to move relative to the receiving part 12 through the moving part 22.

[0043] For example, the fixed portion 21 can be configured to match the derrick within the wellbore 5, facilitating installation of the fixed portion 21 within the wellbore 5. The moving portion 22 can utilize a mechanism or component capable of generating linear motion. For example, the moving portion 22 can utilize a linear motor, hydraulic cylinder, or pneumatic cylinder. The linear motor, hydraulic cylinder, or pneumatic cylinder can be secured to the fixed portion 21, and the transmitting coil 112 in the transmitting portion 11 can be secured to the output component of the linear motor, hydraulic cylinder, or pneumatic cylinder. When installing the adjustment device 2, the motion path of the moving portion 22 can be aligned parallel to the axis Z of the wellbore 5.

[0044] In the above embodiment, since the adjustment device 2 includes the fixed portion 21 and the movable portion 22, the adjustment device 2 can be easily installed in the wellbore 5 via the fixed portion 21. Furthermore, the movable portion 22 can drive the transmitting portion 11 to move, thereby facilitating adjustment of the relative position between the transmitting portion 11 and the receiving portion 12.

[0045] In some possible embodiments of the present application, Figure 4 As shown, the fixed part 21 includes a base 211, which can be installed on the wellbore 5; the moving part 22 includes a driving member 221 and a transmission assembly 222, the driving member 221 is arranged on the base 211, the transmission assembly 222 is arranged on the base 211, and is connected to the output part of the driving member 221, and the transmitting part 11 is fixed on the transmission assembly 222; the driving member 221 is used to drive the transmission assembly 222 to drive the transmitting part 11 to move relative to the receiving part 12.

[0046] In the embodiment of the present application, the fixed portion 21 can be configured as a structure including a base 211. For example, the base 211 can be configured as a box-shaped structure with a groove. The moving portion 22 can be configured as a structure including a driving member 221 and a transmission assembly 222, so that the driving member 221 drives the transmission assembly 222 to generate linear motion.

[0047] Exemplarily, the driving member 221 can be a stepper motor, a servo motor, etc., and the transmission assembly 222 can use a matching sprocket and chain, or a pulley and belt. The motor can be fixed outside the box-shaped base 211, and the output portion of the motor can extend through the base 211 into the base 211. Two sprockets or two pulleys can be rotatably arranged in the base 211, and the output portion of the motor can be connected to one of the sprockets or pulleys. The transmitting unit 11 can be fixedly connected to the chain or belt. In this way, when the motor drives the sprocket or pulley to rotate, it can drive the chain or belt to generate linear motion, thereby driving the transmitting unit 11 to generate linear motion.

[0048] In the above embodiment, since the driving member 221 and the transmission assembly 222 are both disposed on the base 211, assembly of the driving member 221 and the transmission assembly 222 is facilitated, and the base 211 can also provide protection for the driving member 221 and the transmission assembly 222. Furthermore, the driving member 221 can drive the transmission assembly 222 to move, thereby driving the launcher 11 to move.

[0049] In some possible embodiments of the present application, Figure 4 As shown, the transmission assembly 222 includes a matching screw 2221 and a nut 2222. The screw 2221 is rotatably set on the base 211 and is transmission-connected to the output part. The nut 2222 is slidingly connected to the base 211 along the axis of the screw 2221, and the transmitting part 11 is fixedly connected to the nut 2222.

[0050] In the embodiment of the present application, the transmission assembly 222 can use a matching screw 2221 and a nut 2222. The screw 2221 can be rotatably arranged in the box-shaped base 211, and the nut 2222 can be slidably connected to the base 211. For example, a chute parallel to the axis of the nut 2222 can be provided on the base 211, and a protrusion that can extend into the chute can be provided on the nut 2222. The output shaft of the motor serving as the driving member 221 can be connected to the screw 2221. In this way, when the motor drives the screw 2221 to rotate, the nut 2222 can generate a linear motion along the axis of the screw 2221 under the constraints of the protrusion and the chute.

[0051] For example, a ball can be provided between the screw 2221 and the nut 2222 , that is, the transmission component 222 can adopt a ball screw, which is beneficial to improving the motion accuracy of the transmission component 222 and reducing the wear of the transmission component 222 .

[0052] In the above embodiment, since the transmission assembly 222 includes the screw 2221 and the nut 2222, the rotational motion of the driving member 221 can be converted into linear motion of the nut 2222 by the nut 2222 and the screw 2221, thereby driving the launcher 11 to generate linear motion by the nut 2222. Furthermore, the screw 2221 and the nut 2222 have a simple structure, making them easy to maintain and service.

[0053] In some possible embodiments of the present application, Figure 4 As shown, the fixing portion 21 further includes a guide assembly 212 , and the nut 2222 is slidably connected to the base 211 via the guide assembly 212 .

[0054] In this embodiment of the present application, a guide assembly 212 can be provided within the fixed portion 21 to guide and restrict the motion path of the launcher 11. For example, the guide assembly 212 can be implemented as a matching sliding rod and slider, or a guide rail and slider. The sliding rod or guide rail can be positioned parallel to the screw 2221 on the base 211. The slider and nut 2222 can be fixedly connected via a connecting plate, and the launcher 11 can be fixed to the connecting plate. In this manner, the nut 2222 can be slidably connected to the base 211 via the guide assembly 212.

[0055] In the above embodiment, since a guide assembly 212 is provided in the fixing portion 21 and the nut 2222 is connected to the guide assembly 212, the nut 2222 can be slidably connected to the base 211 through the guide assembly 212, and the movement path of the transmitting portion 11 connected to the nut 2222 can be limited and guided by the guide assembly 212, which is conducive to the transmitting portion 11 moving relative to the receiving portion 12 along an accurate path.

[0056] In some possible embodiments of the present application, Figure 1 As shown, the detection device 3 includes a detection component 31 and a signal processing component 32. The detection component 31 is used to be arranged between the tank cage 4 and the wellbore 5, and is electrically connected to the signal processing component 32. The signal processing component 32 is electrically connected to the controller 23 of the adjustment device 2, and is used to generate a first control signal according to the signal generated by the detection component 31.

[0057] In an embodiment of the present application, the detection device 3 can be set to a structure including a detection component 31 and a signal processing component 32, so that the detection component 31 generates a signal that can detect the relative position of the transmitting part 11 and the receiving part 12, and the signal processing component 32 converts the signal generated by the detection component 31 into a first control signal that can control the adjustment device 2 to perform an adjustment action.

[0058] Exemplarily, the detection assembly 31 may be a device capable of generating sound signals, electrical signals, optical signals, electromagnetic signals, etc. For example, the detection assembly 31 may be a laser sensor, an ultrasonic sensor, a contact switch, a Hall sensor, etc. The detection assembly 31 may be disposed on the cage 4, or disposed on the adjustment device 2 adjacent to the transmitter 11. Alternatively, a portion of the detection assembly 31 may be disposed on the cage 4, and another portion of the detection assembly 31 may be disposed on the adjustment device 2 adjacent to the transmitter 11.

[0059] In another example, the detection component 31 can be electrically connected to the signal processing component 32, and the signal processing component 32 can be electrically connected to the controller 23 of the adjustment device 2. The controller 23 of the adjustment device 2 can be a programmable logic controller 23 (PLC). For example, when the optical signal, electrical signal, electromagnetic signal, etc. generated by the detection component 31 is different from the signal generated when the receiving part 12 is in the charging area of the transmitting part 11, the signal processing component 32 can generate a first control signal based on the change in the signal generated by the detection component 31, and send the first control signal to the controller 23 in the adjustment component, so that the adjustment component generates a movement that drives the transmitting part 11 relative to the receiving part 12.

[0060] In the above embodiment, since the detection device 3 includes a detection component 31 and a signal processing component 32, a signal for determining the relative positions of the receiving part 12 and the transmitting part 11 can be generated by the detection component 31, and a first control signal matching the signal generated by the detection component 31 can be generated by the signal processing component 32, thereby accurately controlling the adjustment device 2 to drive the transmitting part 11 to move relative to the receiving part 12.

[0061] In some possible embodiments of the present application, the detection assembly 31 includes an infrared generator and an infrared receiver. The infrared generator is electrically connected to the signal processing device. The infrared generator is arranged on one of the cage 4 and the wellbore 5, and the infrared receiver is arranged on the other of the cage 4 and the wellbore 5.

[0062] In the embodiment of the present application, the detection component 31 can be an infrared sensor. For example, an infrared generator can be disposed on the cage 4, and an infrared receiver can be disposed on the adjustment device 2 located within the shaft 5, adjacent to the transmitting portion 11. Alternatively, the infrared generator can be disposed on the adjustment device 2, adjacent to the transmitting portion 11, and the infrared receiver can be disposed on the cage 4. In this way, the infrared light generated by the infrared generator can be transmitted to the infrared receiver, which then generates a corresponding signal based on the received infrared light.

[0063] In the above embodiment, because detection assembly 31 utilizes an infrared generator and an infrared receiver, the infrared waves are less affected by the dimly lit environment within wellbore 5, thereby improving the accuracy of detecting the relative position of receiving unit 12 and transmitting unit 11. Furthermore, the infrared generator and infrared receiver both consume less power and are smaller in size, saving energy and facilitating installation.

[0064] In some possible embodiments of the present application, the wireless charging device 1 further includes a charging power detection element (not shown in the figure), which is electrically connected to the detection device 3. The charging power detection element is used to detect the charging power of the wireless charging device 1. The charging power detection element is configured to generate a second control signal based on the charging power, and the second control signal is used to control the operating state of the detection device 3.

[0065] In the embodiment of the present application, a device capable of detecting the charging power of the wireless charging device 1 may be provided in the wireless charging device 1 to determine whether the charging power of the wireless charging device 1 is within an appropriate range.

[0066] Exemplarily, the charging power detection component can be a device including a power meter. For example, after the cage 4 moves to the position where the transmitter 11 is located, the transmitter 11 and the power meter can be controlled to work simultaneously. When the power meter detects that the charging power of the wireless charging device 1 is less than the preset power threshold, it may be that the receiving unit 12 is not completely within the sufficient area of the transmitter 11. In this case, the charging power detection component can generate a second control signal and send the second control signal to the detection device 3. The detection device 3 enters the working state in response to the second control signal to determine whether the receiving unit 12 is within the charging area of the transmitter 11 through the detection device 3, thereby determining whether the reason why the charging power of the wireless charging device 1 is less than the preset power threshold is due to a change in the docking position of the cage 4.

[0067] In the above embodiment, since the wireless charging device 1 also includes a charging power detector, the charging power detector can be used to detect whether the charging power of the wireless charging device 1 is normal. If the charging power of the wireless charging device 1 is detected to be low, the charging power detector can control the detection device 3 to enter an operating state. The detection device 3 can then determine whether the low charging power is caused by the receiving unit 12 being outside the charging area of the transmitting unit 11, thereby facilitating rapid identification of the cause of the low charging power of the wireless charging device 1.

[0068] In addition, embodiments of the present application further provide a mining cage system, comprising: a shaft 5, a cage 4, and the mining cage charging device provided in any of the aforementioned embodiments. The cage 4 is hoistably disposed within the shaft 5; a receiving portion 12 is disposed on the cage 4 and electrically connected to a battery 42 within the cage 4; an adjustment device 2 is disposed within the shaft 5; and a detection device 3 is disposed between the cage 4 and the shaft 5.

[0069] In the embodiment of the present application, the size of the cage 4 can be set according to the personnel and materials to be transported, such as Figure 3 As shown, the cage 4 can be set as a box-type structure, and the cage 4 can be set as a double-layer structure. The wellbore 5 can be a structure including a well neck, a well body and a well bottom, and the cage 4 can be set in the wellbore 5 in a liftable manner through a lifting mechanism.

[0070] For example, the receiving portion 12 can be disposed on the cage upper plate 41 of the cage 4 and electrically connected to the battery 42 of the cage 4 via a wire. The adjustment device 2 can be fixedly mounted on a derrick within the wellbore 5, or fixedly mounted on the wall of the wellbore 5. The detection device 3 can be mounted on the cage 4, or mounted on a derrick within the wellbore 5, or a portion of the detection device 3 can be mounted on the cage 4 and another portion of the detection device 3 can be mounted on the adjustment device 2 located within the wellbore 5.

[0071] The mining cage system provided in the embodiment of the present application includes the mining cage charging device provided in any one of the above embodiments, and therefore can achieve stable and reliable charging of the battery 42 in the cage 4.

[0072] At the same time, the embodiment of the present application also provides a control method for a mining cage charging device, which includes a wireless charging device, an adjustment device, and a detection device. The following describes the control method for the mining cage charging device provided in the embodiment of the present application in combination with the mining cage charging device provided in the above embodiment. Figure 5 , Figure 5 This is a flow chart of a control method for a mining cage charging device provided in this application, and the control method includes the following steps S101 to S104.

[0073] S101. When the cage is docked at a preset position relative to the shaft, control the wireless charging device to detect the charging power of the wireless charging device.

[0074] In an embodiment of the present application, when the cage 4 is lifted or lowered to a preset position in the wellbore 5 by the lifting mechanism, that is, when the cage 4 is docked at a position adjacent to the transmitting part 11 of the wireless charging device 1, the transmitting part 11 of the wireless charging device 1 can be controlled to enter a working state to transmit electrical energy to the receiving part 12.

[0075] For example, while controlling the transmitter 11 of the wireless charging device 1 to enter an operating state, the charging power detector in the wireless charging device 1 can be controlled to detect the charging power of the wireless charging device 1. If the receiving unit 12 is within the charging area of the transmitter 11, the detected charging power of the wireless charging device 1 should be within a normal preset power threshold range. If the charging power of the wireless charging device 1 is detected to be less than the preset power threshold, it may be that the receiving unit 12 is not completely within the sufficient area of the transmitter 11, or that the wireless charging device 1 has a fault, or that another component has a fault, preventing normal power transmission to the receiving unit 12.

[0076] S102 : When the charging power is less than a preset power threshold, control the detection device to detect the relative charging position between the receiving unit and the transmitting unit.

[0077] In an embodiment of the present application, the wireless charging device 1 can control the detection device 3 to detect the relative charging positions of the receiving part 12 and the transmitting part 11 to determine whether the charging power is less than the preset power threshold because the receiving part 12 is outside the charging area of the transmitting part 11.

[0078] For example, when the charging power detection component in wireless charging device 1 detects that the charging power is less than a preset power threshold, the charging power detection component can generate a second control signal and transmit the second control signal to detection device 3. Detection device 3 then enters an operating state in response to the second control signal. S103: When the relative charging position is greater than a preset distance, the control adjustment device drives the transmitter to move relative to the receiver until the relative charging position is less than or equal to the preset distance.

[0079] In the embodiment of the present application, when the detection device 3 detects that the distance between the receiving part 12 and the transmitting part 11 along the axial direction Z of the wellbore 5 is greater than the preset distance, that is, the relative charging position between the receiving part 12 and the transmitting part 11 is greater than the preset distance, it can be determined that the receiving part 12 is outside the charging area of the transmitting part 11, or the receiving part 12 is not completely within the charging area.

[0080] For example, a first control signal can be generated by the inspection device and sent to the adjustment device 2. The adjustment device 2 performs an adjustment action in response to the first control signal to drive the transmitting part 11 to move relative to the receiving part 12 along the axial direction Z of the wellbore 5 until the detection device 3 detects that the relative charging position between the transmitting part 11 and the receiving part 12 is less than or equal to the preset distance, that is, the receiving part 12 is completely within the charging area of the transmitting part 11.

[0081] S104: Control the transmitting unit to transmit electric energy to the receiving unit.

[0082] In the embodiment of the present application, after the transmitter 11 is driven to move by the adjustment device 2 so that the receiving unit 12 is within the charging area of the transmitter 11 , the transmitter 11 can be controlled to transmit electrical energy to the receiving unit 12 .

[0083] For example, the transmitter 11 can be controlled to adjust the output voltage and output current, etc., so that the output power of the transmitter 11 meets the requirements for charging the battery 42 of the cage 4. The transmitting coil 112 in the transmitter 11 transfers energy to the receiving coil 122 in the receiving unit 12 through the principle of electromagnetic induction. The receiving host 121 in the receiving unit 12 can be controlled to stabilize the electrical energy so that the current and voltage meet the charging requirements for charging the battery 42 of the cage 4.

[0084] The control method for the charging equipment of the mining cage 4 provided in the embodiment of the present application can reduce the occurrence of inefficient or ineffective charging of the battery 42 of the cage 4 by controlling the wireless charging device 1 to detect the charging power. In addition, when the charging power is less than the preset power threshold, the relative charging position of the receiving part 12 and the transmitting part 11 is detected by the detection device 3 to determine whether the low charging power is caused by the cage 4 not being docked at the preset position. At the same time, by controlling the adjustment device 2 to drive the transmitting part 11 to move relative to the receiving part 12, the receiving part 12 can be placed within the charging area of the transmitting part 11, so that the battery 42 in the cage 4 can be stably and reliably charged by the wireless charging device 1.
