Description

Technical Field

[0001] The present invention relates to the technical field of image communication, and in particular to an intelligent building security device. Background Art

[0002] Smart building security devices are a collection of technical equipment that ensures the safety of people, property and information in buildings. They use advanced information technology, sensor technology, communication technology and other technical means to achieve real-time monitoring, early warning and control of the building environment. From the perspective of the camera, it is a key visual perception component in the security device. The camera can continuously collect visual images in the building area at a certain frame rate. These images contain rich information, such as the activities of people, the location and status of objects, etc.

[0003] Security monitoring equipment located within the building will generate a certain amount of dust in the building area, which will adhere to the camera lens. If a simple scraping and coating method is used for simple cleaning, the dust particles will damage the lens. In some cases, in order to facilitate the flexibility of security work, it is necessary to set the height of the security camera manually. The staff needs to adjust the camera to different heights according to the on-site conditions, but the specific rising distance is unknown to the staff and is not easy to measure. If visual inspection is used, the operator is located below the camera. If it is necessary to observe whether the cleaning parts have reached the camera position, it is necessary to adjust it at a distance or at the same height, which is more cumbersome. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides an intelligent building security device that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent building security device includes an installation box, a camera mechanism is provided on the top of the installation box, and the camera mechanism includes:

[0007] An electric telescopic rod, wherein the electric telescopic rod is located on one side of the top of the installation box;

[0009] a first suspended ceiling, wherein the first suspended ceiling is fixedly mounted on one side of the second suspended ceiling, and a camera is provided at the bottom of the first suspended ceiling;

[0010] A third suspended ceiling, the third suspended ceiling is fixedly mounted on the other side of the second suspended ceiling, and a second pulley and a third pulley are provided on the top of the second suspended ceiling through a structural member;

[0011] Side ropes, one end of each of which is provided with a fixing plate, and a middle rope is provided between each of the side ropes.

[0012] By setting a camera mechanism, a contact sensor is provided at the camera mechanism. After the camera position is set to a height that is not convenient for measurement according to the actual situation on site, the three-way pipe of the lifting mechanism is set to the same height. Specifically, after the contact sensor is pressed, a signal is immediately sent to stop the reel. At this time, the lifting mechanism reaches the height of the camera of the original camera mechanism. There is no need to observe or calculate the height of the camera rise in advance during the whole process, so that the operator does not need to observe the specific height of the cleaning part, and can also move the three-way pipe to a precise height for precise cleaning, avoiding a large amount of cleaning liquid spraying to other parts of the device.

One end of the water pipe is connected to one opening of the three-way pipe, and the other two openings of the three-way pipe are respectively directed to the camera and the electric telescopic rod.

[0018] In one embodiment of the present invention, the other end of the water pipe is provided with a floating mechanism located inside the water storage chamber, and the floating mechanism includes a sliding rod, and the end of the rod body of the sliding rod is connected to the inner wall of the installation box through a sliding rail, and the end of the sliding rod is provided with a counterweight block, and the side of the counterweight block is provided with a fourth pulley, and the fourth pulley is provided with a second limit rod located on the outside of the water pipe.

[0019] In one embodiment of the present invention, a fixing rod is provided on one side of the sliding rod, and the end of the fixing rod is connected to the inner wall of the mounting box, and a fifth pulley is provided on the end of the fixing rod, and the fifth pulley is fixedly connected to the water pipe. A submersible pump is provided below the first pulley, and floating balls are provided around the submersible pump through a connecting shaft.

[0021] In one embodiment of the present invention, a reel is provided on one side of the second shaft platform, and the rotating shaft of the reel is connected to the rotating shaft of the first rotating ring. A servo motor is provided on the other side of the second shaft platform, and the output shaft of the servo motor is connected to the rotating shaft of the reel.

[0022] In one embodiment of the present invention, a second swivel is provided on the main body of the third shaft platform through a movable axis, a symmetrical hook is provided on the side of the second swivel, the protrusion of the symmetrical hook is movably overlapped with the spinous process, a pendulum is provided on the circular part of the second swivel through a connecting axis, a cylinder located on the side of the pendulum is provided on the top of the installation box, and a movable frame located below the pendulum is provided at the output end of the cylinder.

[0023] The invention provides an intelligent building security device, which has the following beneficial effects:

[0024] 1. By setting a camera mechanism, a contact sensor is provided at the camera mechanism. After the camera position is set to a height that is not convenient for measurement according to the actual situation on site, the three-way pipe of the lifting mechanism is set to the same height. Specifically, after the contact sensor is pressed, a signal is immediately sent to stop the reel. At this time, the lifting mechanism reaches the height of the camera of the original camera mechanism. There is no need to observe or calculate the height of the camera rise in advance during the whole process, so that the operator does not need to observe the specific height of the cleaning part, and can also move the three-way pipe to a precise height for precise cleaning, avoiding a large amount of cleaning liquid spraying to other parts of the device. At the same time, during the rising process of the water pipe with a cleaning function, the first roller located in the inner circle of the installation circle will adapt to the different sizes of the telescopic part of the electric telescopic rod under the action of the first spring compression shaft, and during the rising and falling process of the lifting mechanism, the three-way pipe can still spray to clean the floating dust of the device components passing by, and the cleaned water can return to the water storage chamber and settle. Combined with the floating ball of the floating mechanism, the submersible pump can be located near the top of the liquid surface of the water body, and always absorbs relatively clear water from the upper layer.

[0025] 2. By setting the first limit rod, when the mounting circle is at the highest point, the vertical center line of the three-way pipe and the center of the camera lens are located at the same horizontal plane. When the mounting circle reaches the highest position, that is, the height of the camera, the contact sensor will tend to the submersible pump to supply water to directly clean the camera. Due to the limiting effect of the first limit rod, when the contact sensor contacts the first mounting block at the top of the mounting circle, the mounting circle will stop rising, that is, reach the precise height of the camera to be cleaned, thereby avoiding the position error of the cleaning part to a considerable extent and ensuring the cleaning effect. In addition, during the ascent and subsequent descent, the three-way pipe will clean the lifting mechanism and the camera mechanism, thereby ensuring that the camera takes clear pictures and other parts of the device will not be affected by dust particles.

[0026] 3. By setting up the escapement mechanism, during the rising process of the lifting mechanism, the symmetrical hook will pass over the spinous process. Although it is not completely limited, the side ropes and the middle ropes will be stuck to a certain extent during the contact and departure process, which is convenient for shaking the floating dust on the related parts. After the lifting mechanism has cleaned the camera part, the fixed plate can be intermittently and gradually lowered slowly to avoid poor control of the free fall speed during the falling process. When the lifting mechanism encounters the connection part of the electric telescopic rod, it gets stuck and causes the water pipe to fall off. During the falling process of the lifting mechanism, since the water pipe passes through the first mounting block, the first mounting block of the lifting mechanism can be combined with the active fourth pulley of the floating mechanism to tighten the water pipe during the falling process. The fourth pulley with the counterweight block will press the lowest end of the water pipe downward, so that the water pipe has a reasonable activity space to avoid scattering and falling off.

[0041] Example

[0042] See also Figure 1-10The present invention provides a technical solution: an intelligent building security device, comprising an installation box 1, a camera mechanism 2 is arranged on the top of the installation box 1, the camera mechanism 2 comprises an electric telescopic rod 201, a second ceiling 203, a first ceiling 202, a third ceiling 204, and a side rope 208, the electric telescopic rod 201 is located on one side of the top of the installation box 1, the second ceiling 203 is fixedly installed on the top of the rod body of the electric telescopic rod 201, the top of the second ceiling 203 is provided with a first pulley 205 through a structural member, a first limiting rod 2031 is arranged on one side of the bottom of the second ceiling 203, a contact sensor 2032 is arranged on the bottom of the first limiting rod 2031, the first ceiling 202 is fixedly installed on one side of the second ceiling 203, the first ceiling 2 02 is provided with a camera 2021 at the bottom, the third ceiling 204 is fixedly installed on the other side of the second ceiling 203, the top of the second ceiling 203 is provided with a second pulley 206 and a third pulley 207 through a structural member, one end of the side rope 208 is provided with a fixing plate 210, and an intermediate rope 209 is provided between the side ropes 208. When in use, the staff drives the electric telescopic rod 201 to the required height according to actual conditions to perform intelligent security work of the building. Since the security equipment of the building is generally set outdoors or in open places, it is inevitable that the camera 2021 will be contaminated with dust. When the camera 2021 needs to be cleaned after a certain period of use, a servo motor 506 is set on one side of the reel 505. The servo motor 506 is selected as a bidirectional motor and can rotate forward and backward. The reel 505 reels the rope, which is specifically manifested in the lifting of the middle rope 209 and the side rope 208, which is manifested in the rising action on the mounting ring 301. After rising to a certain height, the top of the first mounting block 305 contacts the contact sensor 2032, and then the mounting ring 301 is limited and cannot rise. At the same time, the contact sensor 2032 will send a signal to the reel 505 equipped with a control element, the submersible pump 406 and the camera 21, the reel 505 stops working, the camera 21 flips and aligns with the three-way pipe 307, and the water pump extracts water in the water storage chamber 101 and sprays it to the camera 2 021 lens and other related spraying ranges are cleaned. At this time, the spinous process 5041 of the first rotating ring 504 is limited by the symmetrical hook 508. After the cleaning is completed, the cylinder 511 is set. The cylinder 511 moves the movable frame 510. The movable frame 510 pushes the bottom of the pendulum 509 so that the upper half of the symmetrical hook 508 leaves the spinous process 5041. Then the movable frame 510 continues to move to an area that does not affect the swing range of the pendulum 509. When the pendulum 509 returns to the original path under the action of gravity, the lower part of the symmetrical hook 508 will limit the spinous process 5041 again. Repeat the above operation. The symmetrical hook 508 on one side of the pendulum 509 will make the first rotating ring 504 with the spinous process 5041 perform a stuttering intermittent rotation.The lifting mechanism 3 with the mounting ring 301 can be steadily and intermittently dropped by the connected side rope 208 and the middle rope 209. When the first roller 3031 and the second roller 3041 contact the socket of the electric rope rod, the first spring pressure shaft 303 and the second spring pressure shaft 304 will shrink their respective rollers. At the same time, the water pipe 309 on the first mounting block 305 will move downward. Since the first mounting block 305 also moves downward, the first mounting block 305 of the lifting mechanism 3 can tighten the water pipe 309 in combination with the movable fourth pulley 404 of the floating mechanism 4 during the falling process. The fourth pulley 404 with the counterweight block 403 will press the lowest end of the water pipe 309 downward. By setting the camera mechanism 2, a contact sensor 2032 is provided at the camera mechanism 2. After the position of the camera 21 is set to a height that is not convenient for measurement according to the actual situation on site, the three-way pipe 307 of the lifting mechanism 3 is set to the same height, specifically the contact sensor 2032. After being pressed, a signal is immediately sent to stop the reel 505 from working. At this time, the lifting mechanism 3 reaches the height of the camera 2021 of the original camera mechanism 2. The whole process does not need to be observed or calculated in advance. The height of the camera 2021 rises, so that the operator does not need to observe the specific height of the cleaning part, and can also move the three-way pipe 307 to a precise height for precise cleaning, avoiding a large amount of cleaning liquid spraying to other parts of the device. At the same time, during the rising process of the water pipe 309 with a cleaning function, the first roller 3031 located in the inner ring of the mounting ring 301 will adapt to the different sizes of the telescopic part of the electric telescopic rod 201 under the action of the first spring compression shaft 303, and during the rising and falling process of the lifting mechanism 3, the three-way pipe 307 can still perform a spraying action to clean the floating dust of the device parts passing by, and the cleaned water can return to the water storage chamber 101 and settle. Combined with the floating ball 407 of the floating mechanism 4, the submersible pump 406 can be located near the top of the liquid surface of the water body, and always absorb relatively clear water from the upper layer.

[0043] See also Figure 1-10 A water storage chamber 101 is provided in the installation box 1, and a distribution box accommodating chamber 102 is provided on the side of the water storage chamber 101.

When the mounting circle 301 reaches the highest position, that is, the height of camera 2021, the contact sensor 2032 will tend to the submersible pump 406 to supply water to directly clean the camera 221. Due to the limiting effect of the first limiting rod 2031, when the contact sensor 2032 contacts the first mounting block 305 at the top of the mounting circle 301, the mounting circle 301 will stop rising, that is, it will reach the precise height of the camera 221 to be cleaned, which avoids the position error of the cleaning part to a considerable extent and ensures the cleaning effect. In the process of rising and subsequent descent, the three-way pipe 307 will clean the lifting mechanism 3 and the camera mechanism 2 by the way, ensuring that the camera 2021 takes clear pictures while other parts of the device will not be affected by dust particles.

The pipe body of the water pipe 309 successively bypasses the fifth pulley 405 and the fourth pulley 404 and is plugged into the second mounting block 306. The water pipe 309 on the first mounting block 305 will move downward. Since the first mounting block 305 also moves downward, the first mounting block 305 of the lifting mechanism 3 can tighten the water pipe 309 in combination with the movable fourth pulley 404 of the floating mechanism 4 during the falling process, and the fourth pulley 404 with the counterweight block 403 will press the lowest end of the water pipe 309 downward.

The body of the first shaft platform 501 is provided with a first rotating ring 504 through a movable shaft, and the outer ring of the first rotating ring 504 is provided with a spinous process 5041. By setting the escapement mechanism 5, during the rising process of the lifting mechanism 3, the symmetrical hook 508 will pass through the spinous process 5041. Although it is not completely limited, the side rope 208 and the middle rope 209 will be stuck to a certain extent during the contact and departure process, which is convenient for shaking the floating dust on the relevant components. After the lifting mechanism 3 cleans the camera 2021, the fixing plate 210 can be intermittently and gradually slowly dropped to avoid poor free fall speed control during the falling process. When the lifting mechanism 3 encounters the connection part of the electric telescopic rod 201, it is stuck, causing the water pipe 309 to fall off. During the falling process of the lifting mechanism 3 In the process, since the water pipe 309 passes through the first mounting block 305, the first mounting block 305 of the lifting mechanism 3 can tighten the water pipe 309 in combination with the movable fourth pulley 404 of the floating mechanism 4 during the falling process, and the fourth pulley 404 with the counterweight block 403 will press the lowest end of the water pipe 309 downward, so that the water pipe 309 has a reasonable activity space and is prevented from falling off. When the water pipe 309 is lowered, the first spring compression shaft 303 and the second spring compression shaft 304 will retract their respective rollers. At the same time, the water pipe 309 on the first mounting block 305 will move downward. Since the first mounting block 305 also moves downward, the first mounting block 305 of the lifting mechanism 3 can tighten the water pipe 309 in conjunction with the movable fourth pulley 404 of the floating mechanism 4 during the falling process. The fourth pulley 404 with the counterweight block 403 will press the lowest end of the water pipe 309 downward.

[0051] See also Figure 1-10A second rotating ring 507 is provided on the body of the third shaft platform 503 through a movable shaft, a symmetrical hook 508 is provided on the side of the second rotating ring 507, and the protrusion of the symmetrical hook 508 is movably overlapped with the spinous process 5041, and a pendulum 509 is provided on the circular part of the second rotating ring 507 through a connecting shaft, and a cylinder 511 located on the side of the pendulum 509 is provided on the top of the installation box 1, and a movable frame 510 located below the pendulum 509 is provided at the output end of the cylinder 511. The protrusion 5041 is limited by the symmetrical hook 508. After cleaning is completed, the cylinder 511 is set. The cylinder 511 moves the movable frame 510. The movable frame 510 pushes the bottom of the pendulum 509, so that the upper half of the symmetrical hook 508 leaves the spinous process 5041, and then the movable frame 510 continues to move to an area that does not affect the swing range of the pendulum 509. When the pendulum 509 returns to the original path under the action of gravity, the lower part of the symmetrical hook 508 will limit the spinous process 5041 again.

[0052] Specifically, the working process or working principle of the intelligent building security device is as follows: when in use, the staff drives the electric telescopic rod 201 to the required height according to the actual situation to perform intelligent security work of the building. Since the security equipment of the building is generally installed outdoors or in an open place, it is inevitable that the camera 2021 will be contaminated with dust. When the camera 2021 needs to be cleaned after a certain period of use, a servo motor 506 is set on one side of the reel 505. The servo motor 506 is selected as a bidirectional motor and can rotate forward and reverse. The reel 505 reels the rope, which is specifically manifested as the middle rope 209 and the side rope 208 are pulled, which is manifested in the installation ring 301 as an ascending action. After rising to a certain height, the top of the first installation block 305 contacts the contact sensor 2032, and then the installation ring 301 is limited and cannot rise. At the same time, the contact sensor 2032 will send a signal to the reel 505 equipped with a control element, the submersible pump 406 and the camera. The head 2021 is turned over and aligned with the three-way pipe 307. The water pump draws water from the water storage chamber 101 and sprays it to the lens of the camera 2021 and other related spraying ranges for cleaning. At this time, the spinous process 5041 of the first rotating ring 504 is limited by the symmetrical hook 508. After the cleaning is completed, the cylinder 511 is set, and the cylinder 511 moves the movable frame 510. The movable frame 510 pushes the bottom of the pendulum 509 so that the upper half of the symmetrical hook 508 leaves the spinous process 5041, and then the movable frame 51 0 continues to move to an area that does not affect the swing range of the pendulum 509. When the pendulum 509 returns to the original path under the action of gravity, the lower part of the symmetrical hook 508 will limit the spinous process 5041 again. Repeat the above operation. The symmetrical hook 508 on one side of the pendulum 509 will make the first rotating ring 504 with the spinous process 5041 perform a stuttering intermittent rotation. Through the connected side ropes 208 and the middle rope 209, the lifting mechanism 3 with the mounting ring 301 can be steadily and intermittently dropped, and the lifting mechanism 3 with the mounting ring 301 can be steadily and intermittently dropped on the first roller 3031 and the second roller 3031. When 41 contacts the socket of the electric rope rod, the first spring compression shaft 303 and the second spring compression shaft 304 will retract their respective rollers. At the same time, the water pipe 309 on the first mounting block 305 will move downward. Since the first mounting block 305 also moves downward, the first mounting block 305 of the lifting mechanism 3 can tighten the water pipe 309 in combination with the movable fourth pulley 404 of the floating mechanism 4 during the falling process. The fourth pulley 404 with the counterweight block 403 will press the lowest end of the water pipe 309 downward.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
