Description

Technical Field

[0001] The present invention relates to the technical field of electrical construction safety protection, and particularly to an electrical construction laser curtain wall system and a lens cleaning method thereof. Background Art

[0002] With the rapid development of technology, safety protection technology is increasingly widely used in modern society. In the field of architecture, as an important part of modern buildings, the safety and stability of curtain walls are crucial for the protection function of the entire building. However, traditional curtain wall protection systems often rely on manual monitoring and physical protection, which have problems such as large monitoring blind spots, slow response speed, and high false alarm rates, and are difficult to cope with increasingly complex safety threats.

[0003] Therefore, a three-dimensional laser curtain wall intrusion alarm system has been developed. The three-dimensional laser curtain wall intrusion alarm system uses laser heads to generate laser curtain walls, and multiple laser curtain walls form a three-dimensional electronic fence. When an object crosses the electronic curtain wall, the system automatically generates an alarm signal through sound, light, and electricity. This system is applicable to the construction sites of lines and substations and pedestrian safety prevention, and is a high-tech electronic product.

[0004] The three-dimensional protection of the laser curtain wall requires the laser heads and cameras to be configured near the electrical construction area. However, for some areas with severe problems of dust dispersion due to dry weather and dry soil at the construction site, the dust generated during construction is easily adhered to the surface of the camera, affecting the clarity of the captured images, thus affecting the identification of the identities of intruding pedestrians and causing obstacles to subsequent investigations. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an electrical construction laser curtain wall system and a lens cleaning method thereof. Through the synergistic effect of the dust suction groove and the eccentric cleaning disc, combined with the turbulent flow guidance of the diversion block, the ability to remove dust on the surface of the lens is achieved.

[0006] To achieve the above purpose, in the first aspect, the present invention provides an electrical construction laser curtain wall system, including a laser module, a camera module, and an alarm module. The laser module is used to form a laser curtain wall in the construction area. The camera module is used to capture pedestrians passing through the laser curtain wall and activate the alarm module to send out an alarm signal. The camera module includes a controller and a camera. The camera is connected to the controller through a mounting seat, and the mounting seat is rotatably connected to the controller. The camera is rotatably embedded in the mounting groove on the mounting seat, and the camera is driven to rotate relative to the mounting seat by a driving motor. A dust suction groove is provided on the inner wall of the mounting groove. The dust suction groove communicates with a pumping device, and cleaning bristles are provided inside the dust suction groove. The cleaning bristles are used to clean the lens surface of the camera.

[0007] Beneficial effects: The dust suction groove is communicated with the air extraction device, so that the air around the lens is drawn into the dust suction groove, and the airflow carries away the dust and impurities on the lens surface, realizing the purification of the lens surface, ensuring the clarity of the images collected by the camera, and thus improving the monitoring accuracy of pedestrians who stray into the construction area.

[0008] Furthermore, an annular sealing ring is provided at the edge part of the inner wall of the installation groove. The sealing ring is made of an elastic material and is in contact with the outer surface of the camera. Air outlet holes are evenly arranged on the part of the camera surface surrounding the lens, and an air inlet is provided at the part of the camera outer surface far from the lens. The air outlet holes and the air inlet are communicated, and a filter screen is provided at the air inlet.

[0009] Beneficial effects: The sealing ring is in contact with the camera surface to form an approximately closed environment. When the air extraction device is started, the supplementary air flows in from the air inlet, passes through the filter screen and then flows out from the air outlet holes, realizing the full coverage and cleaning of the lens surface. At the same time, it prevents external dust from entering the gap between the installation groove and the camera, keeping the camera rotating smoothly.

[0010] Furthermore, a cleaning disk is arranged inside the dust suction groove. The cleaning disk is connected to the output end of the rotating device arranged at the bottom of the dust suction groove. Cleaning bristles are distributed on the end part of the cleaning disk close to the camera. A recovery cavity is arranged inside the cleaning disk, and the air extraction device is located inside the recovery cavity. The recovery cavity is communicated with the middle part of the cleaning disk through a recovery hole.

[0011] Beneficial effects: The rotation of the cleaning disk drives the cleaning bristles to brush the lens surface, cleaning the dust adhered tightly. At the same time, the airflow flows in from the air outlet holes, flows towards the central recovery hole along the gap between the cleaning disk and the lens, forming a transverse scouring effect, further carrying away the dust and reducing the adhesion of dust on the cleaning bristles.

[0012] Furthermore, an annular flow guiding block is evenly arranged around the middle recovery hole at the end part of the cleaning disk. The cross section of the flow guiding block is triangular, and the cleaning bristles are distributed on the inclined surface of the flow guiding block facing away from the recovery hole.

[0013] Beneficial effects: The flow guiding block guides the airflow to flow along the inclined surface towards the lens surface, enhancing the scouring effect of the airflow on the lens surface and improving the cleaning efficiency.

[0014] Furthermore, the inside of the flow guiding block is hollow to form a flow guiding cavity. The flow guiding cavity is communicated with the inside of the recovery hole through a flow guiding channel. Dust suction holes are evenly arranged on the inclined surface of the flow guiding block, and the dust suction holes are communicated with the inside of the flow guiding cavity.

[0015] Beneficial effects: Part of the airflow enters the diversion cavity through the dust suction holes, and then converges into the recovery holes through the diversion channels, realizing the near recovery and cleaning of the dust falling off the cleaning brush hairs, and reducing the re - adhesion of dust to the lens surface.

[0016] Furthermore, annular cleaning cone blocks are uniformly arranged at the gap positions between the cleaning brush hairs on the inclined surface of the diversion block. Friction grooves are uniformly arranged on the cleaning cone blocks, and the dust suction holes are located inside the friction grooves.

[0017] Beneficial effects: The cleaning cone blocks collide with the cleaning brush hairs, causing the brush hairs to deform and embed into the friction grooves. The dust adhered to the cleaning brush hairs is sucked into the dust suction holes, and at the same time, the brush hairs are sorted to prevent agglomeration.

[0018] Furthermore, the output end of the rotating device is eccentrically connected to the bottom of the cleaning disk, and the distance between the central axis of the output end of the rotating device and the central axis of the cleaning disk is greater than the distance between adjacent diversion blocks.

[0019] Beneficial effects: The cleaning disk rotates eccentrically, causing the cleaning brush hairs to swing eccentrically while rotating, covering more areas of the lens surface and enhancing the cleaning effect; at the same time, the airflow circulates and vibrates annularly in the gap area, further improving the cleaning efficiency.

[0020] Furthermore, the rotating device is located on the output end of the telescopic device at the bottom of the dust suction groove, and the diversion block and the cleaning disk are elastically connected.

[0021] Beneficial effects: The telescopic device can control the cleaning disk to approach or move away from the lens, facilitating the cleaning operation and the rotation of the camera; the elastically connected diversion blocks vibrate under the impact of the airflow, driving the cleaning brush hairs to vibrate, accelerating the dust shedding, and ensuring the cleaning effect of the cleaning brush hairs.

[0022] In a second aspect, the present invention provides a lens cleaning method for cleaning the lens of the electrical construction laser curtain wall system according to any one of the first aspects, including the following steps:

[0023] S1. Control the driving motor to drive the camera to rotate so that the lens is aligned with the dust suction groove;

[0024] S2. Start the air extraction device to extract the air in the dust suction groove to form a negative pressure;

[0025] S3. Start the rotating device to drive the cleaning disk to rotate so that the cleaning brush hairs clean the lens surface;

[0026] S4. Blow out airflow through the air outlet to assist in cleaning the dust on the lens surface;

[0027] S5. The dust enters the recovery cavity through the recovery holes for collection.

[0028] In summary, compared with the prior art, the present invention can effectively solve the problem of soot adhesion to the camera lens at the construction site, ensure the clarity of image acquisition, improve the accurate monitoring of pedestrians who stray into dangerous construction areas, and thus enhance the construction safety factor. The overall system structure is compact and the operation is simple, with significant practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Specifically, a cleaning disc 34 is provided inside the dust suction groove 32. The cleaning disc 34 is connected to the output end of a rotating device 35 provided at the bottom of the dust suction groove 32. The cleaning brushes 33 are distributed on the end of the cleaning disc 34 close to the camera 2.

[0043] Specifically, a recovery cavity 341 is provided inside the cleaning disc 34. The pumping device is located inside the recovery cavity 341. The recovery cavity 341 communicates with the middle part of the cleaning disc 34 through a recovery hole 342.

[0044] Further, an annular flow guiding block 343 is uniformly provided at the end of the cleaning disc 34 around the middle recovery hole 342. The cross section of the flow guiding block 343 is triangular, and the cleaning brushes 33 are distributed on the inclined surface of the flow guiding block 343 facing away from the recovery hole 342.

[0045] Specifically, the inside of the flow guiding block 343 is hollow to form a flow guiding cavity 344.

[0046] Further, annular cleaning cone blocks 347 are evenly arranged at the gap positions between the cleaning bristles 33 on the inclined surface of the diversion block 343. Friction grooves 348 are evenly arranged on the cleaning cone blocks 347, and the dust suction holes 346 are located inside the friction grooves 348.

[0047] Specifically, the rotating device 35 is located at the output end of the telescopic device 36 at the bottom of the dust suction groove 32, and the diversion block 343 and the cleaning disk 34 are elastically connected.

[0048] Preferably, the radial width of the diversion block 343 gradually decreases from outside to inside. The width of the outermost diversion block 343 is 3-5 mm, and the width of the innermost diversion block 343 is 1-2 mm.

[0049] When in use, the cleaning method of the lens 23 of the electrical construction laser curtain wall system includes the following steps:

[0050] Control the driving motor to drive the camera 2 to rotate so that the lens 23 is aligned with the dust suction groove 32;

[0051] Start the air extraction device to extract the air in the dust suction groove 32 to form a negative pressure;

[0052] Start the rotating device 35 to drive the cleaning disk 34 to rotate so that the cleaning bristles 33 clean the surface of the lens 23;

[0053] Blow out air flow through the air outlet 21 to assist in cleaning the dust on the surface of the lens 23;

[0054] The dust enters the recovery cavity 341 through the recovery hole 342 for collection.

[0055] Preferably, when it is detected that there are oily contaminants on the surface of the lens 23, control the rotating speed of the rotating device 35 to increase to 1800-2000 rpm, and adjust the air flow speed of the air extraction device to 35-40 m 3 / h, and the duration is 1.2-1.5 times of the standard cleaning cycle.

[0056] In the present invention, a dust suction groove 32 is arranged on the inner wall of the installation groove 31, and the dust suction groove 32 is located at the bottom of the camera 2; when it is found that the captured image is blurred and it may be that there is dust adhering to the lens, start the air extraction device connected to the dust suction groove 2, so that the air around the lens 23 is sucked into the dust suction groove 32. During this process, the air flow flowing along the gap between the lens 23 and the inner wall of the dust suction groove 32 passes through the surface of the lens 23, taking away the dust impurities on the surface of the lens 23 and being sucked into the interior of the dust suction groove 32 for collection, thereby realizing the purification of the surface of the lens 23, ensuring the clarity of the image captured by the camera 2, thus ensuring the accurate monitoring of pedestrians who stray into the dangerous construction area and improving the construction safety factor.

[0057] Example 1

[0058] As shown in the attached drawings of the specification Figures 1 - 6 As shown, during the construction process, in order to prevent pedestrians from accidentally entering the electrical construction area and accidentally touching electrical equipment, which may lead to serious electrical accidents and cause losses to personnel and property, it is necessary to formulate preventive measures to prevent pedestrians from approaching the construction area; the present invention provides an electrical construction laser curtain wall system, which can build a three-dimensional electronic fence in the construction area, realize unmanned and efficient monitoring, prevent the intrusion of pedestrians, and ensure construction safety;

[0059] Specifically, it includes a laser module, a camera module and an alarm module. The laser module includes a laser head device, which can form a laser curtain wall in the construction area. The camera module is used to capture pedestrians passing through the laser curtain wall in a timely manner, and at the same time activate the alarm module to send an alarm signal to warn pedestrians and construction workers. The camera module includes a controller 1 and a camera 2. The camera 2 is located on the upper side of the controller 1 body and is connected to the controller 1 body through a mounting seat 3. A battery 4 and a transmission antenna 5 are also installed on the controller 1 body;

[0060] The mounting seat 3 is rotatably connected to the controller 1. The spherical camera 2 is rotatably embedded in the mounting groove 31 on the mounting seat 3, and the rotation of the camera 2 is driven by a driving motor;

[0061] A dust suction groove 32 is arranged inside the mounting groove 31. The dust suction groove 32 is communicated with a pumping device, and cleaning bristles 33 are arranged inside the dust suction groove 32. The cleaning bristles 33 are used to clean the surface of the lens 23 of the camera 2.

[0062] Specific working process: Place the laser head of the laser module at the entrance of the electrical construction area. Utilizing the characteristics of the laser beam, save the relative position measurement data of surrounding space objects during initial defense deployment to form an invisible laser curtain wall.

[0063] When an unauthorized object such as a pedestrian or vehicle invades the fence, it will cause a change in the relative position measurement data of the objects inside the laser curtain wall, and determine whether an intrusion behavior has occurred; when it is determined to be an intrusion behavior, the corresponding control system of the laser module will send a signal in real time, and at the same time activate the camera module, so that the camera 2 configured on the camera module takes pictures of the intruding personnel to retain evidence; when the alarm is triggered, the alarm of the alarm module is activated to release an audible and visual alarm signal. On the one hand, it warns pedestrians to stay away from the dangerous construction area, and on the other hand, it notifies the construction safety personnel to come and dissuade and disperse the pedestrians and vehicles that have strayed in, reducing the situation of pedestrians invading the dangerous construction area and further improving the construction safety factor;

[0064] Further, regarding the camera module of the present invention, the spherical camera 2 is rotatably arranged on the mounting base 3, and the mounting base 3 is also rotatably connected to the body of the controller 1. The motor set at the rotatable connection position can be started by the remote control of the security personnel, so that the mounting base 3 rotates horizontally relative to the body of the controller 1, and the camera 2 can rotate vertically relative to the mounting groove 31. In this way, the shooting and monitoring range of the lens 23 on the camera 2 can be effectively expanded, the dead angle of shooting can be reduced, the monitoring efficiency can be improved, and the full acquisition of on-site image data of the construction area can be ensured;

[0065] Further, due to the serious problem of smoke and dust dispersion at the construction site, the smoke and dust generated during construction adhering to the surface of the lens 23 may affect the clarity of image acquisition of the camera 2, thereby affecting the accuracy of monitoring of intruding pedestrians and increasing difficulties for subsequent identity recognition; Therefore, a dust suction groove 32 is provided on the inner wall of the mounting groove 31, and the dust suction groove 32 is located at the bottom of the camera 2; When it is found that the captured image is blurred and it is likely that there is dust adhering to the lens 23, the connected motor is started to drive the camera 2 to rotate vertically, so that the lens 23 rotates to a position facing the dust suction groove 32; Subsequently, the air extraction device connected to the dust suction groove 32 is started, and the air around the lens 23 is drawn into the dust suction groove 32. During this process, the airflow flowing along the gap between the lens 23 and the inner wall of the dust suction groove 32 passes through the surface of the lens 23, taking away the dust impurities on the surface of the lens 23 and being sucked into the dust suction groove 32 for collection, realizing the purification of the surface of the lens 23, ensuring the clarity of the images collected by the camera 2, and also ensuring the accurate monitoring of pedestrians who stray into the dangerous construction area, and improving the construction safety factor.

[0066] Embodiment 2

[0067] On the basis of Embodiment 1, an annular sealing ring 311 is provided at the edge part of the inner wall of the mounting groove 31. The sealing ring 311 is made of an elastic material and is in contact with the outer surface of the camera 2; Air outlet holes 21 are evenly arranged on the surface of the camera 2 around the lens 23, and an air inlet 22 is provided at a position on the outer surface of the camera 2 away from the lens 23. The air outlet holes 21 and the air inlet 22 are communicated, and a filter screen 221 is provided at the air inlet 22; The lens 23 and the air outlet holes 21 are respectively located on both sides of the camera 2; A filtering mesh structure with a larger mesh number can also be provided inside the air outlet holes 21 to further filter and purify the outflowing air;

[0068] Specific working process: Based on the specific working process in Embodiment 1, when the lens 23 rotates to face the dust suction groove 32, at this time, the sealing ring 311 contacts the area on the surface of the camera 2 outside the lens 23, making the gap area between the lens 23 and the inner wall of the dust suction groove 32 in an approximately closed environment; after the air extraction device is started, the gap area is in a negative pressure state, and the supplementary inflowing air flows in from the air inlet 22 on the camera 2, passes through the filtration of the filter screen 221, and then flows out from the air outlet 21 surrounding the lens 23, flowing towards the middle dust suction groove 32, realizing full coverage cleaning of the lens 23; and controlling the source of the inflowing air flow, so that the supplementary inflowing air flow is first purified by the filter screen 221 and flows in from the air inlet 22 far from the lens 23; the air flowing in from the outer area of the installation groove 31 will be intercepted by the sealing ring 311, preventing external air flow from flowing into the gap between the installation groove 31 and the camera 2, avoiding dust and impurities mixed in by external air from adhering to the gap area between the installation groove 31 and the camera 2, affecting the normal rotation adjustment of the camera 2, and ensuring the normal operation of the camera 2.

[0069] Regarding the dust and impurities adhering to the filter screen 221 during continuous operation, the camera 2 can be rotated so that the corresponding part of the filter screen 221 rotates to face the dust suction groove 32, and then the air flow flowing in through the air outlet 21 flushes from the inside to the outside, performing a reverse flushing and purification treatment on the filter screen 221 to ensure the normal operation of the filter screen 221.

[0070] Embodiment 3

[0071] Based on Embodiment 2, a cleaning disk 34 is arranged inside the dust suction groove 32. The cleaning disk 34 is connected to the output end of a rotating device 35 arranged on the inner wall of the dust suction groove 32. Here, the rotating device 35 can be selected as a motor device and is controlled by an external controller 1; cleaning bristles 33 are evenly distributed on the end of the cleaning disk 34 close to the camera 2. Here, the cleaning bristles 33 are selected as soft bristles for cleaning the motor device and the camera lens 23, or can also be mixed with bristles of conductive material for eliminating static electricity, eliminating the static electricity on the surface of the lens 23 while cleaning the dust, and reducing the dust adsorption effect; a recovery cavity 341 is arranged inside the cleaning disk 34, and the air extraction device is located inside the recovery cavity 341, and the air extraction device can be selected as a micro air pump device;

[0072] An interception net is arranged between the air extraction device and the opening of the recovery cavity 341 to prevent the inhalation of dust, and the recovery cavity 341 communicates with the middle part of the cleaning disk 34 through a recovery hole 342; the air inlet end of the air extraction device communicates with the inside of the recovery cavity 341, and the air outlet end communicates with the dust suction groove 32. Therefore, the air purified by the interception net can be supplemented into the dust suction groove 32 from the air outlet end, realizing the local circulation of the purified air flow, improving the utilization efficiency of the purified air flow, and reducing the input of external air;

[0073] Furthermore, an air pump device can be arranged inside the dust suction groove 32. When the air pressure increases inside the dust suction groove 32 due to the continuously flowing-in air current, a part of the air current is led out to the outside to maintain the normal air pressure inside the dust suction groove 32.

[0074] Specific working process: On the basis of the specific working process in Embodiment 2, the rotating device 35 is started to drive the cleaning disk 34 to rotate and act on the surface of the lens 23. The cleaning bristles 33 distributed on the cleaning disk 34 come into contact with the surface of the lens 23, and as the cleaning disk 34 rotates, the dust on the surface of the lens 23 is swept, so as to take away the dust impurities that adhere tightly to the surface of the lens 23 and are difficult to clean only by the blowing of the air current.

[0075] The air outlets 21 on the camera 2 are annularly distributed around the lens 23, and the recovery holes 342 are located at the center of the cleaning disk 34, close to the center position of the lens 23. The edge part of the cleaning disk 34 bulges upward so that the top of the cleaning disk 34 presents a bowl-shaped structure, which causes the air current flowing in from the air outlets 21 to be restricted by the bulging part at the edge of the cleaning disk 34. Therefore, it concentrates along the gap between the cleaning disk 34 and the lens 23 and flows from the outside to the central recovery hole 342, forming a transverse air current scouring effect on the surface of the lens 23, fully covering the surface of the lens 23; and the transverse air current passes through the gaps between the cleaning bristles 33, blows the surface of the cleaning bristles 33 and takes away the dust adhering to the contact gap between the cleaning bristles 33 and the lens 23, reducing the continuous adhesion of particulate impurities on the ends of the cleaning bristles 33, which may cause scratches on the surface of the lens 23 when the cleaning bristles 33 sweep the surface of the lens 23, ensuring the safety of the lens 23 on the camera 2, and thus ensuring that the camera 2 can normally play its monitoring role.

[0076] Embodiment 4

[0077] On the basis of Embodiment 3, an annular guide block 343 is uniformly arranged around the middle recovery hole 342 at the end of the cleaning disk 34. The cross-section of the guide block 343 is triangular, with the inclined surface on the side facing away from the recovery hole 342 and the vertical surface on the side close to the recovery hole 342, which enables the inward flowing air current to smoothly cross the guide block 343, increasing the residence time and flow path of the air current in the gap part and enhancing the cleaning effect. The cleaning bristles 33 are distributed on the inclined surface of the guide block 343 facing away from the recovery hole 342; the inside of the guide block 343 is hollow to form a guide cavity 344, and the guide cavity 344 is communicated with the inside of the recovery hole 342 through a guide channel 345, and the guide channel 345 is perpendicular to the recovery hole 342; dust suction holes 346 are uniformly arranged on the inclined surface of the guide block 343, and the dust suction holes 346 are communicated with the inside of the guide cavity 344.

[0078] Specific working process: Based on the specific working process in Embodiment 3, the airflow flowing out from the air outlet 21 first contacts the edge part of the surface of the cleaning disk 34, and then flows from the outside to the inside, passing through the guide blocks 343 evenly distributed in circles. Due to the flowing direction from the outside to the inside, when the airflow passes through the guide blocks 343, it is blocked and flows along the inclined surface of the guide blocks 343 towards the direction close to the surface of the lens 23. When the airflow crosses the end of the guide block 343, a rapid and violent airflow is formed between the end of the guide block 343 and the surface of the lens 23, so that the surface of the lens 23 is subjected to a concentrated flushing effect, thereby fully removing the impurities and dust adhered to the surface of the lens 23.

[0079] Furthermore, since dust suction holes 346 are evenly arranged in the gaps between the cleaning bristles 33 on the inclined surface of the guide block 343, and the guide channel 345 communicating with the guide cavity 344 is communicated with the recovery hole 342, the air flow rate inside the recovery hole 342 is large, which promotes the air inside the guide cavity 344 to flow towards the inside of the recovery hole 342. Therefore, when a part of the laterally flowing airflow contacts the inclined surface part of the guide block 343, it directly flows into the dust suction holes 346 through the gaps between the cleaning bristles 33, so that the impurities and dust adhered to the cleaning bristles 33, especially the dust and impurities at the connection part of the cleaning bristles 33 and the guide block 343, are directly taken into the dust suction holes 346 along with the air flowing into the gaps, and then flow into the guide cavity 344 and converge into the recovery hole 342 along the guide channel 345. In this way, the dust and impurities cleaned from the lens 23 and the cleaning bristles 33 can be recovered by flowing into the dust suction holes 346 between the cleaning bristles 33 nearby after falling off, reducing the problem that the fallen dust and impurities continue to flow along the gap between the cleaning disk 34 and the lens 23 and adhere to the surface of the lens 23 again.

[0080] Embodiment 5

[0081] Based on Embodiment 4, annular cleaning cone blocks 347 are evenly arranged at the gap parts between the cleaning bristles 33 on the inclined surface of the guide block 343. Friction grooves 348 are evenly arranged on the cleaning cone blocks 347, the inner walls of the friction grooves 348 can be subjected to frosted treatment, and the dust suction holes 346 are located inside the friction grooves 348.

[0082] The output end of the rotating device 35 is eccentrically connected to the cleaning disk 34, and the distance between the central axis of the output end of the rotating device 35 and the central axis of the cleaning disk 34 is greater than the distance between adjacent guide blocks 343.

[0083] Specific working process: On the basis of the specific working process in Embodiment 4, the eccentric connection between the rotating device 35 and the cleaning disk 34 is rotated, so that the cleaning disk 34 rotates eccentrically relative to the central axis of the lens 23; Therefore, the cleaning bristles 33 on the eccentrically rotating cleaning disk 34 swing eccentrically while rotating, so that the parts on the surface of the lens 23 that were originally located in the gap area between the guiding blocks 343 are also covered by the swinging cleaning bristles 33, so that the sweeping action on the surface of the lens 23 is more sufficient;

[0084] Moreover, the air flow flowing into the gap area between the lens 23 and the cleaning disk 34 from the air outlet 21 has a tendency to flow towards the central recovery hole 342 due to the influence of the air extraction device on the one hand, and on the other hand, under the action of the guiding blocks 343 on the rotating cleaning disk 34, the air flow in the gap area between adjacent guiding blocks 343 has a tendency to flow circularly around the annular gap area; Therefore, part of the air flow will accumulate in the annular gap area and flow towards the middle recovery hole 342 while flowing circularly; The circularly flowing air flow impacts the surface of the lens 23 from multiple directions, and fully takes away the impurities and dust adhering to the surface of the lens 23; For the air flow accumulated in the annular gap area, due to the centrifugal action of the cleaning disk 34, the accumulated air flow has a tendency to swing to both sides, and the air flow in the annular gap area vibrates, enhancing the scouring and cleaning effect on the impurities adhering to the surface of the lens 23;

[0085] Furthermore, as the air flow impacts the cleaning bristles 33, the cleaning bristles 33 tilt and swing towards the direction close to the cleaning cone block 347. The direct collision between the cleaning bristles 33 and the end of the cleaning cone block 347 causes the cleaning bristles 33 to deform, and part of the cleaning bristles 33 will be embedded in the friction groove 348 and slide in contact with the inner wall of the friction groove 348. During this process, the impurities adhering to the cleaning bristles 33 will be sucked into the dust suction holes 346 inside the friction groove 348, and the vibration and impact action can also play a role in sorting the cleaning bristles 33, preventing the impurities from adhering to cause the cleaning bristles 33 to adhere to each other and agglomerate, affecting the normal function of the cleaning bristles 33.

[0086] Embodiment 6:

[0087] On the basis of Embodiment 5, the rotating device 35 is located on the output end of the telescopic device 36 at the bottom of the dust suction groove 32, and the guiding block 343 and the cleaning disk 34 are elastically connected. Specifically, it can be realized by setting the connecting part of the guiding block 343 and the cleaning disk 34 to be an elastic material to achieve elastic connection;

[0088] Specific working process: Based on the specific working process in Embodiment 5, the telescopic device 36 can be an existing electric telescopic device. When it is necessary to clean the surface of the lens 23, start the telescopic device 36 to drive the cleaning disk 34 to move upward close to the surface of the lens 23 to realize the cleaning operation. After the cleaning is completed, the telescopic device 36 can be controlled to drive the cleaning disk 34 to move downward away from the surface of the camera 2 to prevent the cleaning disk 34 from affecting the smooth rotation of the camera 2.

[0089] An annular groove can be formed by inward depression of the part of the camera 2 around the lens 23, and the air outlet 21 is located inside the annular groove. Therefore, when the telescopic device 36 drives the cleaning disk 34 close to the lens 23, the raised part at the edge of the cleaning disk 34 is embedded in the annular groove, so that the air outlet 21 is surrounded by the gap area between the raised part at the edge of the cleaning disk 34 and the lens 23, making full use of the cleaning air flow. And the width of the annular groove is greater than the width of the raised part at the edge of the cleaning disk 34, providing a margin for the swing of the raised part at the edge of the cleaning disk 34 inside the annular groove when the cleaning disk 34 swings centrifugally.

[0090] Furthermore, due to the elastic connection of the flow guiding blocks 343, when the air flow swings in the gap area between adjacent flow guiding blocks 343 due to centrifugal rotation, the flow guiding blocks 343 vibrate relative to the cleaning disk 34 under the impact of the air flow, thereby driving the cleaning bristles 33 to vibrate, promoting the impurities adhered to the cleaning bristles 33 to fall off more quickly and ensuring the normal operation of the cleaning bristles 33.

[0091] Embodiment 7

[0092] This embodiment provides a lens cleaning method for the lens 23 of an electrical construction laser curtain wall system, including the following steps:

[0093] Monitoring status judgment step: When it is found that the image captured by the camera 2 is blurred, it is judged that dust may adhere to the surface of the lens 23, and the cleaning program is started.

[0094] Camera rotation and positioning step: Start the connected motor to drive the camera 2 to rotate vertically, so that the lens 23 rotates to a position facing the dust suction groove 32, and the sealing ring 311 contacts the area of the camera 2 surface outside the lens 23 to form an approximately closed cleaning environment.

[0095] Air flow cleaning step: Start the air extraction device connected to the dust suction groove 32, so that the air around the lens 23 is drawn into the dust suction groove 32. The supplementary air flows in through the air inlet 22 after being filtered by the filter screen 221 and flows out from the air outlet 21, flowing towards the middle dust suction groove 32 to realize full coverage cleaning of the lens 23.

[0096] Mechanical cleaning step: Start the rotating device 35, drive the cleaning disc 34 to rotate eccentrically and act on the surface of the lens 23, so that the cleaning brush hairs 33 swing and brush the surface of the lens 23; when the cleaning brush hairs 33 collide with the cleaning cone block 347, part of the cleaning brush hairs 33 are embedded in the friction groove 348 for sliding contact, so that the impurities adhered to the cleaning brush hairs 33 are sucked into the diversion cavity 344 through the dust suction holes 346;

[0097] Airflow guiding step: The airflow flowing out of the air outlet 21 generates an annular flow trend under the action of the diversion block 343, so that the surface of the lens 23 is impacted by the airflow in multiple directions; the centrifugal action of the cleaning disc 34 causes the accumulated airflow to vibrate, enhancing the flushing and cleaning effect on the impurities adhered to the surface of the lens 23;

[0098] Reset step: When the cleaning operation is completed, control the telescopic device 36 to drive the cleaning disc 34 to move downwards, away from the surface of the camera 2, so that the camera 2 resumes its normal monitoring working state.
