Description

Technical Field

[0001] This invention belongs to the field of security equipment technology, specifically relating to a monitoring device for intelligent buildings. Background Technology

[0002] Intelligent building is an evolving concept, constantly being updated and supplemented as science and technology advance and people's functional requirements change. The purpose of achieving building intelligence is to create a safe, convenient, comfortable, efficient, and cost-effective living or working environment for users. Any facilities and systems installed within the building must conform to this goal; otherwise, building intelligence loses its meaning.

[0003] Garage security monitoring systems are an important component of intelligent buildings. They can directly view the situation in the monitored area through cameras and auxiliary equipment (lenses, etc.), and can record all or part of the images of the monitored area, thus providing convenient conditions and important evidence for handling certain events in the future.

[0004] However, existing garage security monitoring systems also have some drawbacks. For example, the cameras are fixed installations, so in order to monitor a large area of ​​garage, a large number of cameras need to be installed so that the shooting range can fully cover the garage. Summary of the Invention

[0005] The purpose of this invention is to provide a monitoring device for intelligent buildings that can automatically rotate its camera to follow the movement of vehicles, thereby not only making the images clearer but also increasing the shooting range and reducing the number of cameras required.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A monitoring device for an intelligent building includes a camera, a power mechanism, a locking mechanism, and a rotating mechanism. The camera is mounted on the rotating mechanism, the rotating mechanism is mounted on a wall, the power mechanism and the locking mechanism are installed underground, and the locking mechanism is connected to the rotating mechanism.

[0008] The power mechanism includes multiple power units, each of which includes a hydraulic cylinder installed underground. A piston is connected inside the hydraulic cylinder, and a first spring connects the bottom of the piston to the bottom of the hydraulic cylinder. A piston rod is connected to the piston, and a pressure plate is connected to the top of the piston rod. The top of the pressure plate is flush with the ground. The hydraulic cylinder is connected to an inlet branch pipe and an outlet branch pipe. An inlet check valve is connected to the inlet branch pipe, and an outlet check valve is connected to the outlet branch pipe. A storage tank is also installed underground. The inlet branch pipes of each power unit are connected to the outlet of the storage tank via a main inlet pipe, and the outlet branch pipes of each power unit are connected to the rotating mechanism via a main outlet pipe. The power mechanism is driven without requiring additional electrical power, utilizing the weight of the vehicle, thus saving energy.

[0009] Further specifying, the rotating mechanism includes a housing, which is fixedly mounted on a wall via a mounting bracket. A first rotating shaft is rotatably connected inside the housing. A hydraulic motor and a drive bevel gear are connected to the first rotating shaft. A first locking block is connected to the end face of the drive bevel gear. The hydraulic motor is fixedly connected to the first rotating shaft. The inlet of the hydraulic motor is connected to the main outlet pipe, and the outlet of the hydraulic motor is connected to the inlet of the storage tank. The drive bevel gear is loosely fitted on the first rotating shaft. The middle section of the first rotating shaft is a splined shaft structure. A clutch disc is connected to the splined shaft structure. A first locking groove is opened on the end face of the clutch disc. The clutch disc is connected to a shift disc. A shift lever and a fixed pulley are also rotatably connected inside the housing. The shift lever is connected to the housing via a torsion spring. One end of the shift lever is connected to a shift fork located in the middle of the shift disc. The other end of the shift lever is connected to a first pull rope, which passes over the fixed pulley and is connected to a locking mechanism.

[0010] Further specifying, the housing is also connected to a second rotating shaft, on which a driven bevel gear and a first connecting rod are connected. The driven bevel gear meshes with a driving bevel gear. The first connecting rod is sequentially hinged to a second connecting rod and a third connecting rod. An arc-shaped block is connected to the end of the third connecting rod. A third rotating shaft is connected to the middle of the third connecting rod. The top of the third rotating shaft is connected to a camera. An installation plate is installed inside the housing. The installation plate is connected to an arc-shaped groove. The arc-shaped block is slidably connected within the arc-shaped groove. A second spring is connected between the ends of the arc-shaped block and the arc-shaped groove.

[0011] Further specifying, the locking mechanism includes a first speed bump and a second speed bump, which are installed on the ground. A third spring is connected between the bottom of the first speed bump and the ground. A first rack is connected to the bottom of the first speed bump. A fourth rotating shaft is rotatably connected underground. A first gear, a chuck, and a first pull rope connecting rod are connected to the fourth rotating shaft. The first gear meshes with the first rack. A second slot is provided on the chuck. The first pull rope connecting rod is connected to a lever through a first pull rope.

[0012] Further specifying, a fourth spring is connected between the bottom of the second speed bump and the ground, a second rack is connected to the bottom of the second speed bump, a fifth rotating shaft is rotatably connected underground, a second gear and a second pull rope connecting rod are connected to the fifth rotating shaft, a slide groove is installed underground, a second locking block is slidably connected in the slide groove, a fifth spring is connected between the second locking block and the bottom of the slide groove, and a second pull rope is connected between the second locking block and the second pull rope connecting rod.

[0013] Furthermore, the first card block and the first card slot are respectively provided with matching inclined surfaces. This facilitates the connection between the clutch disc and the drive bevel gear.

[0014] Furthermore, the spring constant of the first spring installed in the middle position is the smallest, and the spring constants of the first springs from the middle to the left and right sides increase sequentially. With this setup, as the car moves, and the distance between the car and the camera increases and then decreases again, the camera's rotation speed also increases and then decreases, thus making the camera's shooting angle more reasonable.

[0015] The present invention also includes a method of using the device, which mainly includes the following steps:

[0016] Step 1: Lock.

[0017] When the car passes over the first speed bump, the car presses down on the first speed bump and the first rack. The first rack moves downward, driving the first gear to rotate. The first gear then drives the first pull rope connecting rod and the chuck to rotate through the fourth rotating shaft. On one hand, the first pull rope connecting rod pulls the lever to rotate through the first pull rope. The lever then drives the clutch disc to move forward through the shift fork, causing the first locking block to engage in the first locking slot, thereby connecting the clutch disc with the driving bevel gear. When the chuck rotates, when the second locking slot rotates to the horizontal position, the second locking block engages in the second locking slot under the push of the fifth spring. The second locking block locks the chuck, thereby preventing the lever from reversing under the action of the torsion spring, and keeping the clutch disc and the driving bevel gear continuously connected.

[0018] Step two, rotate.

[0019] As the car continues to move forward, it presses down the pressure plate, piston rod, and piston as it passes over the pressure plate. The first spring is compressed, and the piston pushes the liquid out of the hydraulic cylinder. The liquid passes through the outlet check valve, outlet branch pipe, and outlet main pipe in sequence. Then, the liquid passes through the hydraulic motor and drives it to rotate. After passing through the hydraulic motor, the liquid enters the storage tank. The hydraulic motor drives the driving bevel gear to rotate through the first rotating shaft. The driving bevel gear then drives the driven bevel gear, the second rotating shaft, and the first connecting rod to rotate. The first connecting rod then drives the third connecting rod to swing around the third rotating shaft through the second connecting rod. The third connecting rod drives the arc-shaped block to slide in the arc groove, thereby compressing the second spring. The rotation of the third rotating shaft drives the camera to rotate.

[0020] When the car passes the rear pressure plate, the piston rod and piston of the front pressure plate are reset under the action of the first spring. At the same time, the liquid in the reservoir is drawn into the hydraulic cylinder through the inlet main pipe, the inlet check valve and the inlet branch pipe. As the car continues to move forward, the hydraulic motor rotates continuously, thereby making the camera rotate continuously.

[0021] Step 3: Reset.

[0022] As the car continues forward, it presses down on the second speed bump and the second rack. The rack moves downward, causing the second gear to rotate. The second gear then rotates the second cable connecting rod via the fifth shaft. The cable connecting rod pulls the second locking block through the second cable, causing it to slide in the groove. The fifth spring is compressed, disengaging the second locking block from the second slot. The lever, under the action of the torsion spring, reverses and resets. The lever then moves the clutch disc via the shift fork, disengaging the first locking block from the first slot, thus disengaging the clutch disc from the drive bevel gear. The arc-shaped block resets under the action of the second spring, and via the third connecting rod, it drives the third shaft and the camera to reverse and reset. Attached Figure Description

Detailed Implementation

[0040] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] like Figures 1 to 14 As shown, this invention discloses a monitoring device for intelligent buildings, installed on one side of a driveway in a garage. The device automatically rotates its camera to follow the movement of vehicles, resulting in clearer images and a wider field of view, thus reducing the number of cameras required. The device includes a camera 1. To enable the camera 1 to follow the vehicle, a power mechanism 2 is also provided. The power mechanism 2 is driven without requiring additional electrical power, utilizing the weight of the vehicle to save energy. Specifically, the power mechanism 2 includes multiple power units 201, which are sequentially installed on the driveway. Each power unit 201 includes a hydraulic cylinder 21, which is installed underground. A piston 22 is connected inside the hydraulic cylinder 21. A first spring 23 is connected between the bottom of the piston 22 and the bottom of the hydraulic cylinder 21. The first spring 23 located in the middle has the lowest elastic coefficient, and the elastic coefficient increases sequentially from the middle to the left and right sides.

[0042] A piston rod 24 is connected to the piston 22, and a pressure plate 25 is connected to the top of the piston rod 24. The top of the pressure plate 25 is flush with the ground. The hydraulic cylinder 21 is connected to an inlet branch pipe 26 and an outlet branch pipe 27. An inlet check valve 28 is connected to the inlet branch pipe 26, and an outlet check valve 29 is connected to the outlet branch pipe 27. A storage tank 210 is also installed underground. The inlet branch pipe 26 of each power unit 201 is connected to the outlet of the storage tank 210 through the inlet main pipe 211. The outlet branch pipe 27 of each power unit 201 is connected to the rotating mechanism 4 through the outlet main pipe 212.

[0043] When the car passes over the pressure plate 25, the car presses down the pressure plate 25, piston rod 24 and piston 22, the first spring 23 is compressed, and the piston 22 pushes out the liquid in the hydraulic cylinder 21. The liquid passes through the liquid outlet check valve 29, the liquid outlet branch pipe 27 and the liquid outlet main pipe 212 in sequence, and then enters the liquid storage tank 210 after passing through the rotating mechanism 4.

[0044] This device also includes a locking mechanism 3, which in turn includes a first speed bump 31 and a second speed bump 32. The first speed bump 31 and the second speed bump 32 are installed on the ground, with the first speed bump 31 installed closer to the oncoming traffic direction than the second speed bump 32, so that the car passes over the first speed bump 31 first and then the second speed bump 32. A third spring 33 is connected between the bottom of the first speed bump 31 and the ground. A first rack 34 is connected to the bottom of the first speed bump 31, and a fourth shaft 35 is rotatably connected underground. A first gear 36, a chuck 37, and a first pull rope connecting rod 38 are connected to the fourth shaft 35. The first gear 36 meshes with the first rack 34. A second slot 371 is provided on the chuck 37. The first pull rope connecting rod 38 is connected to a lever 48 through a first pull rope. A fourth spring 39 is connected between the bottom of the second speed bump 32 and the ground. A second rack 310 is connected to the bottom of the second speed bump 32. A fifth shaft 311 is rotatably connected underground. A second gear 312 and a second rope connecting rod 313 are connected to the fifth shaft 311. A slide 314 is also installed underground. A second locking block 315 is slidably connected inside the slide 314. A fifth spring 316 is connected between the second locking block 315 and the bottom of the slide 314. A second rope is connected between the second locking block 315 and the second rope connecting rod 313.

[0045] In use, when the car passes over the first speed bump 31, the car presses down the first speed bump 31 and the first rack 34. The first rack 34 moves downward, driving the first gear 36 to rotate. The first gear 36 then drives the first pull rope connecting rod 38 and the chuck 37 to rotate through the fourth rotating shaft 35. On one hand, the first pull rope connecting rod 38 pulls the lever 48 to rotate through the first pull rope. The lever 48 then drives the clutch disc 46 to move forward through the shift fork 410, so that the first locking block 451 is locked into the first locking groove 461, thereby connecting the clutch disc 46 with the driving bevel gear 45. In order to facilitate the connection between the clutch disc 46 and the driving bevel gear 45, the first locking block 451 and the first locking groove 461 are respectively provided with mutually matching inclined surfaces.

[0046] On the other hand, when the chuck 37 rotates, when the second slot 371 rotates to the horizontal position, the second block 315 is pushed into the second slot 371 by the fifth spring 316. The second block 315 locks the chuck 37, thereby preventing the lever 48 from reversing under the action of the torsion spring, so that the clutch disc 46 and the drive bevel gear 45 remain in continuous connection.

[0047] This device also includes a rotating mechanism 4, which in turn includes a housing 41. The housing 41 is fixedly mounted on the wall of the garage via a mounting bracket 42. A first rotating shaft 43 is rotatably connected inside the housing 41. A hydraulic motor 44 and a drive bevel gear 45 are connected to the first rotating shaft 43. A first locking block 451 is connected to the end face of the drive bevel gear 45. The hydraulic motor 44 is fixedly connected to the first rotating shaft 43. The inlet of the hydraulic motor 44 is connected to the outlet pipe 212, and the outlet of the hydraulic motor 44 is connected to the inlet of the storage tank 210. The drive bevel gear 45 is empty. The first rotating shaft 43 is fitted onto the first rotating shaft 43. The middle section of the first rotating shaft 43 is a splined shaft structure. A clutch disc 46 is connected to the splined shaft structure. A first slot 461 is opened on the end face of the clutch disc 46. The clutch disc 46 is connected to a toggle disc 47. A lever 48 and a fixed pulley 49 are also rotatably connected inside the housing 41. The lever 48 is connected to the housing 41 through a torsion spring. One end of the lever 48 is connected to a fork 410, which is located in the middle of the toggle disc 47. The other end of the lever 48 is connected to a first pull rope. The first pull rope passes around the fixed pulley 49 and is connected to the locking mechanism 3.

[0048] A second rotating shaft 411 is also connected inside the housing 41. A driven bevel gear 412 and a first connecting rod 413 are connected to the second rotating shaft 411. The driven bevel gear 412 meshes with the driving bevel gear 45. The first connecting rod 413 is sequentially hinged to a second connecting rod 414 and a third connecting rod 415. An arc-shaped block 416 is connected to the end of the third connecting rod 415. A third rotating shaft 417 is connected to the middle of the third connecting rod 415. The top of the third rotating shaft 417 is connected to the camera 1. An mounting plate 418 is installed inside the housing 41. An arc-shaped groove 419 is connected to the mounting plate 418. The arc-shaped block 416 is slidably connected in the arc-shaped groove 419. A second spring 420 is connected between the ends of the arc-shaped block 416 and the arc-shaped groove 419.

[0049] As the car continues to move forward, when it passes the pressure plate 25, it presses down the pressure plate 25, piston rod 24, and piston 22, compressing the first spring 23. The piston 22 pushes out the liquid in the hydraulic cylinder 21. The liquid passes through the outlet check valve 29, outlet branch pipe 27, and outlet main pipe 212 in sequence. Then, the liquid passes through the hydraulic motor 44 and drives the hydraulic motor 44 to rotate. After passing through the hydraulic motor 44, the liquid enters the storage tank 210. The hydraulic motor 44 drives the active bevel gear 45 to rotate through the first rotating shaft 43. The active bevel gear 45 then drives the driven bevel gear 412, the second rotating shaft 411, and the first connecting rod 413 to rotate. The first connecting rod 413 then drives the third connecting rod 415 to swing around the third rotating shaft 417 through the second connecting rod 414. The third connecting rod 415 drives the arc block 416 to slide in the arc groove 419, thereby compressing the second spring 420. The rotation of the third rotating shaft 417 drives the camera 1 to rotate with the car.

[0050] When the car passes the rear pressure plate 25, the piston rod 24 and piston 22 of the front pressure plate 25 are reset under the action of the first spring 23. At the same time, the liquid in the reservoir 210 is sucked into the hydraulic cylinder 21 after passing through the inlet main pipe 211, the inlet check valve 28 and the inlet branch pipe 26. As the car continues to move forward, the hydraulic motor 44 rotates continuously, thereby causing the camera 1 to rotate continuously.

[0051] As the car continues to move forward, when it passes the second speed bump 32, the car presses down the second speed bump 32 and the second rack 310. The second rack 310 moves downward, causing the second gear 312 to rotate. The second gear 312 then drives the second pull rope connecting rod 313 to rotate via the fifth rotating shaft 311. The second pull rope connecting rod 313 pulls the second locking block 315 to slide in the slide groove 314 via the second pull rope. The fifth spring 316 is compressed, and the second locking block 315 disengages from the second locking groove 371. The lever 48 reverses and resets under the action of the torsion spring. The lever 48 then drives the clutch disc 46 to move in the direction via the shift fork 410, causing the first locking block 451 to disengage from the first locking groove 461, thereby disengaging the clutch disc 46 from the driving bevel gear 45. The arc-shaped block 416 resets under the action of the second spring 420. The arc-shaped block 416 drives the third rotating shaft 417 and the camera 1 to reverse and reset via the third connecting rod 415.

[0052] The present invention also includes a method of using the device, which mainly includes the following steps:

[0053] Step 1: Lock.

[0054] When the car passes over the first speed bump 31, the car presses down on the first speed bump 31 and the first rack 34. The first rack 34 moves downward, driving the first gear 36 to rotate. The first gear 36 then drives the first pull rope connecting rod 38 and the chuck 37 to rotate through the fourth rotating shaft 35. On one hand, the first pull rope connecting rod 38 pulls the lever 48 to rotate through the first pull rope. The lever 48 then drives the clutch disc 46 to move forward through the shift fork 410, so that the first locking block 451 is locked into the first locking groove 461, thereby connecting the clutch disc 46 with the driving bevel gear 45. When the chuck 37 rotates, when the second locking groove 371 rotates to the horizontal position, the second locking block 315 is locked into the second locking groove 371 under the push of the fifth spring 316. The second locking block 315 locks the chuck 37, thereby preventing the lever 48 from reversing under the action of the torsion spring, so that the clutch disc 46 and the driving bevel gear 45 remain continuously connected.

[0055] Step two, rotate.

[0056] As the car continues to move forward, when it passes the pressure plate 25, it presses down the pressure plate 25, piston rod 24, and piston 22, compressing the first spring 23. The piston 22 pushes out the liquid in the hydraulic cylinder 21. The liquid passes through the outlet check valve 29, outlet branch pipe 27, and outlet main pipe 212 in sequence. Then, the liquid passes through the hydraulic motor 44 and drives the hydraulic motor 44 to rotate. After passing through the hydraulic motor 44, the liquid enters the storage tank 210. The hydraulic motor 44 drives the active bevel gear 45 to rotate through the first rotating shaft 43. The active bevel gear 45 then drives the driven bevel gear 412, the second rotating shaft 411, and the first connecting rod 413 to rotate. The first connecting rod 413 then drives the third connecting rod 415 to swing around the third rotating shaft 417 through the second connecting rod 414. The third connecting rod 415 drives the arc block 416 to slide in the arc groove 419, thereby compressing the second spring 420. The rotation of the third rotating shaft 417 drives the camera 1 to rotate.

[0057] When the car passes the rear pressure plate 25, the piston rod 24 and piston 22 of the front pressure plate 25 are reset under the action of the first spring 23. At the same time, the liquid in the reservoir 210 is sucked into the hydraulic cylinder 21 after passing through the inlet main pipe 211, the inlet check valve 28 and the inlet branch pipe 26. As the car continues to move forward, the hydraulic motor 44 rotates continuously, thereby causing the camera 1 to rotate continuously.

[0058] Step 3: Reset.

[0059] As the car continues to move forward, when it passes the second speed bump 32, the car presses down the second speed bump 32 and the second rack 310. The second rack 310 moves downward, causing the second gear 312 to rotate. The second gear 312 then drives the second pull rope connecting rod 313 to rotate via the fifth rotating shaft 311. The second pull rope connecting rod 313 pulls the second locking block 315 to slide in the slide groove 314 via the second pull rope. The fifth spring 316 is compressed, and the second locking block 315 disengages from the second locking groove 371. The lever 48 reverses and resets under the action of the torsion spring. The lever 48 then drives the clutch disc 46 to move in the direction via the shift fork 410, causing the first locking block 451 to disengage from the first locking groove 461, thereby disengaging the clutch disc 46 from the driving bevel gear 45. The arc-shaped block 416 resets under the action of the second spring 420. The arc-shaped block 416 drives the third rotating shaft 417 and the camera 1 to reverse and reset via the third connecting rod 415.
