Description

Technical Field

[0001] This utility model belongs to the field of security monitoring technology and relates to a security monitoring device for underground parking garages. Background Technology

[0002] Underground parking garages, also known as underground parking lots, are buildings constructed underground to park motor vehicles of various sizes. They mainly consist of parking spaces, passageways, ramps or mechanical lifts, entrances and exits, and shunting areas. In recent years, the development of underground parking garages has been extremely rapid. However, the environment in underground parking garages is often dimly lit with low visibility, making them ideal locations for crime. Therefore, installing surveillance equipment in underground parking garages is particularly important. Existing surveillance devices are generally cameras with flash illumination. Over time, the lens surface of these cameras easily accumulates dust, affecting image quality. Furthermore, due to the flash, cobwebs easily form around the camera, further affecting image quality. Manual cleaning requires climbing tools to reach heights, which is time-consuming, labor-intensive, and unsafe.

[0003] According to the inspection institute, Chinese patent CN209330274U discloses a security monitoring and detection device for underground parking garages, including a mounting plate. A PLC controller is mounted on the side surface of the mounting plate, and a fixed column is connected to the lower surface of the mounting plate. A voice recognition device, a photosensitive sensor, and an alarm are mounted on the outer surface of the fixed column. A connecting column is connected to the bottom of the fixed column, and three second motors are mounted on the outer side of the connecting column. The output shafts of the second motors are connected to rotating shafts, and rotating rods are fixedly connected to the rotating shafts. A camera device is connected to the bottom of each rotating rod, and a smoke sensor and a carbon monoxide sensor are mounted on the outer surface of one of the camera devices. However, this device, when used in existing underground parking garages, still cannot overcome the aforementioned problems.

[0004] Therefore, this utility model provides a security monitoring device for underground parking garages to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses an underground garage security monitoring device. The technical solution adopted is as follows: It includes a mounting base, which includes a fixing plate with mounting holes at four corners. A rectangular shell is fixedly connected to the lower surface of the fixing plate. A partition is set in the middle of the interior of the rectangular shell. A base plate is installed at the lower end of the rectangular shell. A magnetic female connector is embedded in a groove in the middle of the lower surface of the base plate. Wire holes are symmetrically opened on the left and right sides of the magnetic female connector. A winding spool is rotatably inserted into the center of the left and right side walls of the rectangular shell and the center of the partition. The left end of the winding spool is fixedly connected to the output shaft of a motor installed on the left outer wall of the rectangular shell. The same traction rope is wound around the left and right sides of the winding spool on the partition. The left and right traction ropes pass through the corresponding left and right wire holes. The lower ends of the left and right traction ropes are fixedly connected to camera assemblies. The camera assembly includes a mounting plate. A magnetic male connector adapted to the magnetic female connector is embedded in a groove in the middle of the top of the mounting plate. A monitoring camera electrically connected to the magnetic male connector is installed in the middle of the lower part of the mounting plate.

[0006] As a preferred embodiment of this utility model, holes are made at the left front corner and the right rear corner, which are symmetrical about the center, respectively, to install miniature electric actuators. When the telescopic shaft of the miniature electric actuator retracts to its original position, its end is flush with the lower surface of the base plate. By using two centrally symmetrical miniature electric actuators, when it is necessary to clean the surface of the surveillance camera, the two symmetrical miniature electric actuators can be controlled to extend downwards simultaneously, causing the base plate to overcome the attraction between the magnetic male connector and the magnetic female connector, thereby causing both ends of the mounting plate to separate from the base plate at the same time. With the action of the motor and the winding shaft, the surveillance camera can automatically fall.

[0007] As a preferred embodiment of this utility model, a wire ring is fixedly installed on the upper opening edge of the wire hole, and a conical surface is opened on the lower opening edge of the wire hole. A groove is opened on the bottom plate around the magnetic female connector. By using a wire ring, the wear of the traction rope is reduced. The conical surface opened at the bottom of the wire hole facilitates the matching with the conical positioning post at the bottom of the traction rope, so as to realize the rapid positioning between the camera assembly and the bottom when it moves upward.

[0008] As a preferred embodiment of this utility model, the bottom end of the traction rope is fixedly connected to a conical positioning post, and the bottom of the left and right conical positioning posts are fixedly installed on the left and right sides of the upper part of the mounting plate; by using two identical traction ropes, the rotation of the camera assembly during the upward movement is effectively suppressed to a certain extent, ensuring the correct connection between the magnetic male connector and the magnetic female connector.

[0009] As a preferred embodiment of this utility model, a sealing ring is formed on the mounting plate around the magnetic male connector; by using the sealing ring, it is easy to cooperate with the groove at the bottom of the base plate to achieve dustproof sealing.

[0010] As a preferred embodiment of this utility model, a microcontroller is installed on the fixing plate on the top left side of the rectangular housing, and the microcontroller is electrically connected to the magnetic female connector. By using the magnetic female connector and the magnetic male connector to connect, on the one hand, power is provided to the camera assembly, and on the other hand, after the magnetic female connector and the magnetic male connector are connected, the connection signal is fed back to the microcontroller, so that the microcontroller can control the motor to stop.

[0011] The beneficial effects of this utility model are as follows: By using the motor in the mounting base to drive the winding shaft, the symmetrical traction ropes on the left and right sides are simultaneously raised and lowered to lift the camera assembly, lens cleaning can be completed without climbing. With the help of the conical positioning post, the conical surface of the cable hole, and the wire ring, the lifting process is guaranteed to be free of shaking and cable wear, thus effectively solving the problem of difficult traditional cleaning and maintenance.

Detailed Implementation

[0017] Example 1

[0018] like Figures 1 to 4As shown, the underground garage security monitoring device of this utility model adopts the following technical solution: It includes a mounting base 1, which includes a fixing plate 11 with mounting holes at four corners. A rectangular shell 12 is fixedly connected to the lower surface of the fixing plate 11. A partition 13 is provided in the middle of the interior of the rectangular shell 12. A base plate 14 is installed at the lower end of the rectangular shell 12. A magnetic female connector 15 is embedded in a groove in the middle of the lower surface of the base plate 14. Wire holes 141 are symmetrically opened on the base plates on both sides of the magnetic female connector 15. A wire ring 142 is fixedly installed at the upper opening edge of the wire hole 141, and a conical surface 143 is opened at the lower opening edge of the wire hole 141. A groove 144 is formed around the base plate surrounding the magnetic female connector 15. A winding shaft 2 is rotatably inserted into the center of the left and right side walls of the rectangular shell 12 and the center of the partition 13. The left end of the winding shaft 2 is fixedly connected to the output shaft of a motor 3 installed on the left outer wall of the rectangular shell 12. The winding shaft 2 is located on the partition 1. The left and right sides of the 3 are respectively wrapped with the same traction rope 4. The left and right traction ropes 4 pass through the corresponding wire holes 141. The bottom end of the traction rope 4 is fixedly connected to the conical positioning post 41. The lower ends of the left and right traction ropes 4 are respectively fixedly connected to the camera assembly 5 through the conical positioning post 41. The camera assembly 5 includes a mounting plate 51. The top center of the mounting plate 51 has a slot in which a magnetic male connector 52 adapted to the magnetic female connector 15 is embedded. The lower center of the mounting plate 51 is equipped with a monitoring camera 53 that is electrically connected to the magnetic male connector 52. A sealing ring 54 is opened on the mounting plate 51 around the magnetic male connector 52. The left front corner and the right rear corner symmetrical about the center of the base plate 14 are respectively opened to install miniature electric push rods 6. When the telescopic shaft of the miniature electric push rod 6 is retracted to its original position, its end is flush with the lower surface of the base plate 14. A microcontroller 7 is installed on the fixed plate on the top left side of the rectangular housing 12. The microcontroller 7 is electrically connected to the magnetic female connector 15.

[0019] The microcontroller 7 uses an IoT-enabled controller, which can be controlled via a mobile app or Bluetooth connection.

[0020] The working principle of this utility model is as follows: During the device installation stage, the overall structure is first fixed to the top of the underground garage through the mounting holes at the four corners of the fixing plate 11 in the mounting base 1; the partition 13 inside the rectangular shell 12 divides the winding spool 2 into two independent winding areas, left and right. The two ends of the winding spool 2 are respectively rotatably inserted into the center of the left and right side walls of the rectangular shell 12 and the center of the partition 13. Its left end is fixed to the output shaft of the motor 3 on the left outer wall of the rectangular shell 12. At the same time, the two traction ropes 4 are respectively wound around the left and right sides of the winding spool 2. The lower end of the traction rope 4 passes through the corresponding wire hole 141 on the bottom plate 14 and is fixed to the upper left and right sides of the mounting plate 51 of the camera component 5 through the conical positioning post 41, thus completing the device assembly.

[0021] Under normal monitoring conditions, the magnetic male connector 52 embedded in the top of the mounting plate 51 of the camera assembly 5 precisely aligns with the magnetic female connector 15 embedded in the groove in the middle of the lower surface of the base plate 14. The sealing ring 54 on the mounting plate 51 surrounding the magnetic male connector 52 is embedded in the groove 144 of the base plate 14 surrounding the magnetic female connector 15 to achieve a seal. The microcontroller 7, mounted on the top left fixing plate 11 of the rectangular housing 12, supplies power to the monitoring camera 53 and transmits data through an electrical connection with the magnetic female connector 15. The monitoring camera 53 is mounted in the lower middle of the mounting plate 51 and electrically connected to the magnetic male connector 52 to continuously perform security monitoring.

[0022] When the lens of the surveillance camera 53 needs to be cleaned, the microcontroller 7 sends a command to start the motor 3. At the same time, it controls the left and right symmetrical micro electric push rods 6 to extend their telescopic shafts, separating the mounting plate 51 from the base plate 14. The motor 3 drives the winding shaft 2 to rotate in the opposite direction, releasing the traction ropes 4 wound on its left and right sides. When the traction rope 4 moves in the wire hole 141, the wire ring 142 at the upper opening edge of the wire hole 141 reduces the wear of the traction rope 4, and the conical surface 143 at the lower opening edge prevents the traction rope 4 from getting stuck. Under the action of the gravity of the camera assembly 5, the traction rope 4 drives the mounting plate 51 and the surveillance camera 53 to descend smoothly through the conical positioning post 41 until it reaches a height on the ground that is easy to clean. At this time, the motor 3 can be stopped to perform the lens cleaning operation. After cleaning is completed, the microcontroller 7 controls the motor 3 to rotate in the forward direction, the winding shaft 2 retracts the traction rope 4, and drives the camera assembly 5 to rise and reset until the magnetic male connector 52 connects with the magnetic female connector 15 again. At the same time as the connection is completed, the connection signal is fed back to the microcontroller 7 through the magnetic female connector 15, controlling the motor 3 to stop rotating.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
