[0022] Example 1

[0023] like Figure 1-2 As shown, this utility model discloses a lifting rodent-proof barrier device, including a control board 1, a camera 7, a symmetrical drive unit, a symmetrical transmission unit, a plate unit, a limit unit, a power supply unit, and a switch unit. The outer side of the control board 1 is provided with a shell plate 20, which is fixedly connected to the base plate 16 by bolts. The control board 1 and the camera 7 are electrically connected. The camera 7 is fixedly installed at a preset position of the device, and its installation position can effectively detect the doorway area. The reduction motor 15 in the symmetrical drive unit is electrically connected to the control board 1. The lead screw nut 3 in the symmetrical drive unit is connected to the slider 10 in the symmetrical transmission unit through a connecting piece. The connecting piece is made of metal, and the slider 10 and the connecting piece are fixedly connected by bolts. The connecting piece and the lead screw nut 3 are fixedly connected by bolts.

[0024] The symmetrical drive unit includes a geared motor 15, a coupling 14, a lead screw 19, and a lead screw nut 3. There are two geared motors 15, two couplings 14, two lead screws 19, and two lead screw nuts 3. The output shaft of each geared motor 15 is connected to one end of the coupling 14, and the other end of each coupling 14 is connected to the lead screw 19. A lead screw nut 3 is fitted on each lead screw 19.

[0025] The symmetrical transmission unit includes two sliders 10 and two guide rails 11. The two guide rails 11 are arranged symmetrically in the vertical direction, and each slider 10 is slidably engaged with one guide rail 11.

[0026] The slider 10 is fixedly connected to the upper plate 8 in the plate unit. The plate unit includes the upper plate 8, the middle plate 6 and the bottom plate 16. The upper plate 8 is fixedly connected to the two sliders 10. The sides of the upper plate 8 and the middle plate 6 are connected by the drawer guide rail 5. The front of the upper plate 8 and the middle plate 6 are separated by the nylon liner 12. The sides of the middle plate 6 and the bottom plate 16 are connected by the drawer guide rail 5. The front of the middle plate 6 and the bottom plate 16 are separated by the nylon liner 12.

[0027] The limit unit includes an upper limit position 9 and a lower limit position 13, both of which are electrically connected to the control board 1. The upper limit position 9 is located above the guide rail 11 in the symmetrical transmission unit, and the lower limit position 13 is located below the guide rail 11 in the symmetrical transmission unit. The power supply unit includes a power plug 17 and a power supply 18. The input terminals of the power plug 17 and the power supply 18 are connected, and the output terminal of the power supply 18 is electrically connected to the control board 1.

[0028] The power switch 2 is connected in series in the circuit between the power plug 17 and the power supply 18. The electric switch 4 in the switch unit is electrically connected to the control board 1.

[0029] Working principle: The rodent-proof barrier is installed at the door. When a person enters, the camera 7 detects the person and sends a signal to the control board 1. The control board 1 will start the geared motor 15 to run and drive the lead screw 19 to rotate through the coupling 14. The rotation of the lead screw 19 will cause the lead screw nut 3 to move up and down along the lead screw 19.

[0030] The lead screw nut 19 and the slider 10 are connected by a connecting piece, and the slider 10 moves up and down along the guide rail 11 following the lead screw nut 3. The upper plate 8 is connected to the slider 10. The movement of the slider 10 causes the upper plate 8 to move up and down. The upper plate 10 and the middle plate 6 are connected on the side by a drawer guide rail 5, and separated on the front by a nylon liner 12.

[0031] The middle plate 6 and the bottom plate 16 are connected by drawer slides 5 on the sides, and the front is also isolated by nylon lining 12. The up and down movement of the top plate 8 will drive the up and down movement of the middle plate 6. When it reaches the bottom, the middle plate 6 fits together with the bottom plate 16 and extends into the bottom plate 16, facilitating personnel entry. When the lower limit 13 is triggered, the control board 1 will stop supplying power to the reduction motor 15. After the camera 7 does not detect personnel and delays for 5 seconds, the control board 1 controls the reduction motor 15 to reverse, driving the top plate 8 to rise, which in turn drives the middle plate 6 to rise, triggering the upper limit 9 and stopping. At this time, the rodent barrier is in the rodent-blocking state. The entire device is powered by 220VAC. Power is introduced through the power connector 17, and the voltage is reduced to 12VDC by the 12V power supply 18 for use by the control board 1.

[0032] Through the electrical connection between camera 7 and control board 1, personnel entering and exiting can be automatically detected and the board body can be raised and lowered: when personnel enter, control board 1 drives the symmetrical drive unit to lower the upper board 8 and the middle board 6, and the middle board 6 and the bottom board 16 are fitted together to form a passageway; after personnel leave, it automatically rises to the rodent-blocking state, without manual operation, solving the problem of traditional fixed rodent-blocking boards obstructing passage.

[0033] The mirror arrangement of the dual reduction motors 15 and dual lead screws 19 in the symmetrical drive unit with the dual sliders 10 and dual guide rails 11 in the symmetrical transmission unit ensures that the upper plate 8 is subjected to balanced forces, avoids tilting or jamming caused by unilateral drive, and ensures a smooth lifting process.

[0034] Metal connecting plates and bolted connections enhance the connection strength between the lead screw nut 3 and the slider 10, improving transmission efficiency and structural durability. The upper plate 8, middle plate 6, and bottom plate 16 are connected by drawer rails 5, enabling layered telescopic movement: when descending, the middle plate 6 extends into the bottom plate 16, reducing space occupation; when ascending, the multiple layers unfold to form a continuous rodent barrier, meeting rodent-proof requirements; nylon lining 12 isolates the front of the plates, reducing friction loss during lifting and extending the device's service life. The upper limit 9 and lower limit 13, in conjunction with the control board 1, precisely limit the lifting endpoint, preventing structural damage caused by overtravel.

[0035] The 12V power supply 18 conversion circuit adapts to the operating voltage of the control board 1, and combined with the power switch 2, it enables flexible power-off, reducing energy consumption while ensuring circuit safety.

[0036] When the device is not in a passable state, the multi-layered panels unfold to form a closed barrier, using a rigid structure to prevent rodents from passing through; the 220VAC power supply combined with the 12VDC control circuit is compatible with conventional mains power environments and can be stably applied to various doorway scenarios.

[0037] The system automatically lowers the barrier to approximately 200mm above the ground upon detecting personnel entering or exiting, allowing staff to easily step over it. The barrier also retains some height even after lowering to prevent small animals from entering with people. When no personnel are detected, the barrier automatically returns to its normal height. If the sensor fails to detect personnel for any reason, the barrier can be manually lowered via a button and then automatically raised after a delay.

[0038] Intelligent rodent-proof barriers are suitable for use in power distribution rooms, substations, grain depots, and other similar locations. They can be installed at the bottom of door frames or ventilation openings, where rodents may enter, improving the safety and convenience of personnel access.

[0039] Press the power switch; the green power indicator light will illuminate, powering on the device. After 5 seconds of power-on, a long beep will be heard, indicating that the sensor initialization is complete.

[0040] When a staff member approaches within one meter of the rodent barrier, the barrier automatically lowers when the sensor detects a human figure or movement (such as reaching out a hand). After a 5-second delay at the bottom, the barrier automatically rises. If another person is detected during the rising process, the barrier pauses its ascent and resumes lowering until no more people can be detected, at which point it rises to the top. When the barrier is at the bottom, the delay time will be appropriately extended if multiple people are detected entering or exiting consecutively.

[0041] Sensor recognition is affected by light, and when human figure recognition sensitivity is low, human motion sensing will improve recognition accuracy. When motion cannot be recognized, a person can press the jog button on the top of the mouse barrier, and the mouse barrier will automatically lower, and after a 5-second delay, it will automatically rise again.

[0042] Therefore, this utility model adopts the above-mentioned lifting rodent-proof barrier device to achieve automatic lifting and improve passage convenience; ensure lifting stability and structural reliability; optimize the multi-layer plate arrangement to balance rodent blocking and space utilization; accurately control the operating status to ensure safety and energy saving, and enhance the continuity and adaptability of the rodent-proof function.

[0043] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and such modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
