Description

Technical Field

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

[0002] Monitoring devices are an especially important component in the development of intelligent and secure buildings. They mostly refer to television monitoring systems connected to burglar alarm systems. The main body of the monitoring device is a monitoring probe, which can capture real-time real-life images and record them in storage devices through information recording and storage technology, thereby achieving 24-hour uninterrupted monitoring of designated locations and facilitating people to trace and view them later, so as to achieve intelligent monitoring and security visualization of the building system. Television security monitoring systems usually consist of four parts: front-end equipment, transmission network, control center, and display terminal. Images are captured by cameras, sent to the control center for processing via the transmission network, and finally displayed in real time on televisions or monitors. Some systems combine AI technology to realize abnormal behavior recognition (such as retrograde, fire warning) and intelligent analysis (such as crowd statistics).

[0003] The monitoring probe mainly includes a protective cover and a camera. Electrical components are installed inside the protective cover. The coordinated work of multiple electrical components will generate high heat, which will eventually be concentrated inside the cover. A large amount of heat will accelerate the aging of the circuit and the stability of the electrical components.

[0004] To solve the above problems, we proposed an intelligent building security monitoring device. Summary of the invention

[0007] In the above-mentioned building intelligent security monitoring device, a limit seat is fixed on the lower side wall of the cover body. A vertical opening is penetrated through the limit seat. A limit opening and a notch are formed on the outer wall of the limit seat. Sealing plates one and two are respectively fixed on the outer walls of the upper and lower ends of the limit seat. A motor is fixed on the sealing plate two. The driving end of the motor penetrates through the sealing plate two and is fixedly connected to a rotating plate that rotates along the inner wall of the limit opening. The end of the air inlet pipe is inserted into the limit seat. A plurality of uniformly distributed filter mesh cylinders are installed on the rotating plate. The motor drives the rotating plate to rotate to switch different filter mesh cylinders to be located in the limit seat.

[0008] In the above-mentioned building intelligent security monitoring device, an opening is formed on the sealing plate one. An air flow guiding ring is arranged in the opening. A shunt pipe is connected to the upper side wall of the exhaust pipe. The end of the shunt pipe penetrates and extends into the air flow guiding ring. A backwashing opening that matches the position of the air flow guiding ring is formed on the sealing plate two.

[0009] In the above-mentioned building intelligent security monitoring device, a rotating shaft is installed at the installation opening on the outer wall of the cover body. A gear and a brush plate are fixed at the end of the rotating shaft. An arc-shaped pipe is fixed on the outer wall of the cover body. Straight pipes are integrally formed at both ends of the arc-shaped pipe. Piston columns are slidably arranged in both straight pipes. Inert gas is filled in the arc-shaped pipe. A connecting rope is fixed between the two piston columns. The end of the piston column close to the limit seat is fixed with a magnet plate located in the notch. A telescopic spring is fixedly connected between the magnet plate and the end of the straight pipe. The end of the other piston column is fixedly connected to a right-angle plate. Teeth that mesh with the gear are arranged on the outer wall of the right-angle plate. Installation openings are formed on the outer wall of the rotating plate between two adjacent filter mesh cylinders. Magnet blocks are fixed in the installation openings.

[0010] In the above-mentioned building intelligent security monitoring device, a right-angle rod is fixedly connected to the sealing plate two. A water tank is fixedly connected to the end of the right-angle rod. A piston plate is slidably arranged in the water tank. A moving rod that penetrates and extends to the inner and outer sides of the water tank is fixed on the outer wall of the piston plate. An impact plate located outside the backwashing opening is fixed at the end of the moving rod. A converging opening is formed on the impact plate. A return spring is fixedly connected between the impact plate and the end of the water tank. Cooling water is filled in the water tank. A drain pipe whose end extends into the cover body is connected to the outer wall of the water tank. The end of the drain pipe is connected to a heat conduction pipe located in the cover body.

[0011] In the above-mentioned building intelligent security monitoring device, the heat conduction pipe is arranged in multiple continuous bent sections.

[0012] In the above-mentioned building intelligent security monitoring device, the brush plate includes a stainless steel plate, and a flexible silica gel layer is fixed on the outer wall of the stainless steel plate.

[0013] In the above-mentioned intelligent building security monitoring device, an inert gas is filled between the two piston rods.

[0014] Compared with existing technologies, the advantages of this building intelligent security monitoring device are: 1. By setting an exhaust pump, an arc-shaped distribution plate and a collection frame, the hot air flow in the cover flows upward and is collected in the collection frame. The hot air flow in the collection frame is pumped out to the arc-shaped distribution plate by the exhaust pump, and is blown out into multiple air flows through the arc-shaped distribution plate to contact the camera, blowing away dust and impurities adhering to the camera mirror surface, thereby cleaning the camera. This achieves the goal of completing the heat dissipation inside the cover and cleaning the camera at the same time. 2. A motor, a rotating plate, a filter cylinder, an arc tube, a piston column, a right-angle plate, a gear, a magnet plate, a magnet block and a brush plate are set. The motor drives the rotating plate to rotate and switch the filter cylinder connected to the inside of the cover body, so as to achieve uninterrupted filtering and purification of the gas. In the process of switching the filter cylinder, the magnetic repulsion between the magnet block and the magnet plate drives the piston column to move to achieve the movement of the right-angle plate, driving the gear and the brush plate to rotate. During the rotation of the brush plate, impurities and dust on the surface of the camera are brushed off, so that the camera can be cleaned every time the filter cylinder is replaced. The airflow blown out by the arc distribution plate is combined to clean and dry the camera, ensuring clear shooting by the camera; 3. A shunt pipe, an airflow guide ring, an impact plate, a water tank, a drain pipe and a heat pipe are arranged. Part of the airflow derived from the exhaust pump is introduced into the airflow guide ring through the shunt pipe. The airflow flows downward to recoil the used filter cylinder, so that the dust and impurities at the end of the filter cylinder are flushed out, and the filter cylinder is cleaned. At the same time, the airflow of the recoil filter cylinder rushes out from the recoil port and contacts the impact plate. The airflow pushes the impact plate to move downward, and the piston plate moves downward to squeeze the cooling water in the water tank into the drain pipe and the heat pipe. The flow of the water body can quickly absorb the heat on the heat pipe, so that the heat pipe can continuously absorb the heat in the cover body and complete the cooling of the cover body. In summary, the present invention extracts the hot air flow in the surveillance camera cover, which on the one hand completes the heat dissipation inside the cover, and on the other hand, can blow away the dust and impurities on the camera surface and dry the water stains. On the other hand, the hot air flow is discharged to recoil the filter cylinder to clean it, and push the impact plate downward to squeeze the water body to flow, thereby accelerating the heat dissipation process in the cover, and realizing the rotation of the brush plate during the switching process of the filter cylinder, so that the filter cylinder switching and the brush plate operation can be carried out simultaneously.

Specific implementation manners

[0017] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0018] Refer to Figures 1-8, a building intelligent security monitoring device, comprising a fixed seat 28, a cover body 1, a camera 2 arranged at the end of the cover body 1, sensors inside the cover body 1 and electrical components. The fixed seat 28 is connected to the cover body 1 through a pan-tilt head. A nano-scale superhydrophobic coating is provided on the surface of the camera 2. An air inlet pipe is provided on the lower side wall of the cover body 1, and an exhaust port is provided on the upper side wall of the cover body 1. A collecting frame 3 is fixed on the upper side wall of the cover body 1 above the exhaust port. An exhaust pump 4 communicating with the inside of the collecting frame 3 is fixed on the upper side wall of the collecting frame 3. An arc-shaped distribution plate 5 is fixed on the upper side wall of the collecting frame 3. An exhaust pipe is connected between the output end of the exhaust pump 4 and the inside of the arc-shaped distribution plate 5. A plurality of exhaust channels facing the camera 2 are provided at the end of the arc-shaped distribution plate 5. By adjusting the angles of the cover body 1 and the camera 2 through the pan-tilt head, the shooting work at different angular positions is realized. The heat generated by the electrical components working inside the cover body 1 flows upward and converges in the collecting frame 3. The hot air flow in the collecting frame 3 is pumped outwards through the exhaust pump 4, discharged into the arc-shaped distribution plate 5 through the exhaust pipe, and then ejected through the exhaust channels. On the one hand, the dust and impurities on the surface of the camera 2 can be blown away by the air flow. On the other hand, when there is moisture and water stains on the surface of the camera 2, the hot air flow contacts it and can quickly evaporate it, avoiding the contamination of the camera 2 mirror caused by the contact and solidification of the water stains and dust.

[0019] A limiting seat 6 is fixed to the lower side wall of the cover body 1, and a vertical opening 7 is provided on the limiting seat 6. A limiting opening and a notch 8 are provided on the outer wall of the limiting seat 6. A sealing plate 1 and a sealing plate 2 18 are respectively fixed to the outer walls of the upper and lower ends of the limiting seat 6. A motor 19 is fixed to the sealing plate 2 18. The driving end of the motor 19 penetrates the sealing plate 2 18 and is fixedly connected to a rotating plate 9 that rotates in accordance with the inner wall of the limiting opening. The end of the air inlet pipe is inserted into the limiting seat 6, and a plurality of evenly distributed filter screen cylinders 11 are installed on the rotating plate 9. The rotating plate 9 is driven by the motor 19 to rotate and switch different filter screen cylinders 11 located in the limiting seat 6. An opening is provided on the sealing plate 1, and an airflow guide ring 27 is provided in the opening. A shunt pipe 26 is connected to the upper side wall of the exhaust pipe, and the end of the shunt pipe 26 extends through and into the airflow guide ring 27. A notch 8 is provided on the sealing plate 2 18 that is connected to the airflow guide ring 2 7 positions match the recoil port, the external airflow is filtered by the filter screen cylinder 11 corresponding to the position of the vertical port 7 and then enters the cover body 1 through the air inlet pipe, so as to realize the purification of the airflow entering the cover body 1. In order to realize the continuous filtration of the airflow, after a single filter screen cylinder 11 has been used for a certain period of time, the motor 19 can drive the rotating plate 9 to rotate to replace the filter screen cylinder 11 located in the limit seat 6. The rotation interval can be controlled by a timer, etc. After use, the filter screen cylinder 11 moves to the lower side of the opening after the rotating plate 9 rotates, and part of the airflow derived from the exhaust pump 4 is derived from the airflow guide ring 27 through the diverter pipe 26, and then flows downward to perform recoil work on the used filter screen cylinder 11, flushing out the impurities in the filter screen cylinder 11, so as to realize the cleaning of the filter screen cylinder 11, and the flushed impurities and dust can fly out freely, so that the filter screen cylinder 11 can be reused.

[0020] The outer wall mounting port of the cover body 1 is provided with a rotating shaft. A gear 16 and a brush plate 17 are fixed to the end of the rotating shaft. The brush plate 17 includes a stainless steel plate, and a flexible silica gel layer is fixed to the outer wall of the stainless steel plate. An arc-shaped tube 12 is fixed to the outer wall of the cover body 1. Straight tubes are integrally formed at both ends of the arc-shaped tube 12. Piston columns are slidably arranged in both straight tubes. Inert gas is filled in the arc-shaped tube 12. A connecting rope is fixed between the two piston columns. A magnet plate 13 located in the notch 8 is fixed to the end of the piston column close to the limit seat 6. A telescopic spring 14 is fixedly connected between the magnet plate 13 and the end of the straight tube. The end of the other piston column is fixedly connected with a right-angle plate 15. Teeth meshing with the gear 16 are arranged on the outer wall of the right-angle plate 15. An installation port is formed in the outer wall of the rotating plate 9 and is located between two filter screen cylinders 11. A magnet block 10 is fixed in the installation port. During the process of the motor 19 driving the rotating plate 9 to rotate, when switching from one filter screen cylinder 11 to another, the magnet block 10 will pass through the notch 8. When passing through, under the action of the magnetic repulsion force between the magnet block 10 and the magnet plate 13, the magnet plate 13 moves towards the side away from the notch 8, pushing the inert gas and the piston column to move. The right-angle plate 15 moves, and drives the gear 16, the brush plate 17 and the rotating shaft to rotate through the meshing of the teeth and the gear 16. The brush plate 17 moves along the surface of the camera 2, scraping off the dust and impurities that have not been blown away on the surface of the camera 2. After the filter screen cylinder 11 rotates into the limit seat 6, the magnet plate 13 and the magnet block 10 are staggered. Under the reverse elastic force of the telescopic spring 14, the magnet plate 13 moves back, pulling the piston column back, and pulling the other piston column and the right-angle plate 15 back through the connecting rope. The brush plate 17 is driven to rotate back to the original position through the meshing of the teeth and the gear 16. Each time the filter screen cylinder 11 is switched, the brush plate 17 can clean the mirror surface of the camera 2, realizing the cleaning of the camera 2 while replacing the filter screen cylinder 11.

[0021] A right-angle rod 20 is fixedly connected to the second sealing plate 18. A water tank 21 is fixedly connected to the end of the right-angle rod 20. A piston plate is slidably arranged in the water tank 21. A moving rod that penetrates and extends to the inner and outer sides of the water tank 21 is fixed to the outer wall of the piston plate. An impact plate 25 located outside the backwash port is fixedly connected to the end of the moving rod. A converging port 29 is formed in the impact plate 25. A return spring 24 is fixedly connected between the impact plate 25 and the end of the water tank 21. The water tank 21 is filled with cooling water. A drain pipe 22 with an end extending into the housing 1 is connected to the outer wall of the water tank 21. A heat conduction pipe 23 located in the housing 1 is connected to the end of the drain pipe 22. The heat conduction pipe 23 is arranged in multiple continuous bends. The airflow of the backwash filter cylinder 11 rushes out from the backwash port and contacts the impact plate 25. The airflow pushes the impact plate 25 to move downward. The provided converging port 29 also has the function of converging the airflow, making the airflow aggregation and pushing effect better. After the impact plate 25 moves downward, the piston plate moves downward to squeeze the cooling water in the water tank 21 into the drain pipe 22 and the heat conduction pipe 23. The heat conduction pipe 23 adsorbs the heat in the housing 1. The heat on the heat conduction pipe 23 is transferred to the cooling water. The piston plate squeezes the water body to flow in the heat conduction pipe 23. When the water molecules contact the pipe wall, they absorb heat through molecular vibration and collision. Through the flow of the water body, the heat on the heat conduction pipe 23 can be quickly adsorbed, enabling the heat conduction pipe 23 to continuously adsorb the heat in the housing 1 and completing the cooling in the housing 1.
