[0031] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0032] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0033] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0034] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0035] like Figure 1-5 As shown, an intelligent security monitoring device for a construction site of the present invention comprises a mounting frame and a security monitoring device, wherein there are multiple security monitoring devices, and the mounting frame comprises a vertical rod 1 and multiple transverse rods 2 which are perpendicular to each other, wherein one end of the transverse rod 2 is connected to the top of the vertical rod 1, and the other end is provided with a security monitoring device via a suspension rod 3, wherein all the transverse rods 2 form a circular structure, and the security monitoring device is a monitoring camera 4.

[0036] In the above implementation scheme, the mounting frame is configured as a vertical rod 1 and a plurality of transverse rods 2, and a plurality of monitoring cameras are arranged on each transverse rod 2, so that a large-area circumferential monitoring of the construction site can be realized without any blind spots.

[0037] Considering that there is a lot of dust and debris at the construction site, the monitoring camera often has the problem of being covered by dust and debris after a period of use, which will cause the monitoring camera clarity to drop significantly, and the natural camera monitoring effect will also be greatly reduced. In order to overcome this technical problem, an embodiment of the present invention has the following design: the intelligent security monitoring device for the construction site further includes a plurality of cleaning boxes 5, which are distributed in an annular shape and correspond to the bottom of each of the monitoring cameras 4, and each cleaning box 5 is provided with a cleaning groove 6, and the inner wall of the cleaning groove 6 is paved with a layer of cleaning sponge 7;

[0038] The vertical rod 1 of the mounting frame is hollow inside;

[0039] A sliding ring 8 is sleeved on the vertical rod 1 of the mounting frame. The sliding ring 8 moves along the vertical direction of the vertical rod 1 under the drive of the driving mechanism. Each cleaning box 5 is vertically connected to the sliding ring 8 through a connecting rod 9. A cleaning groove 6 is arranged in the cleaning box 5. The inner cavity of the cleaning groove 6 is adapted to the monitoring camera 4. The cleaning box is cylindrical.

[0040] The sliding ring 8 can be moved to embed the monitoring camera 4 in the cleaning tank 6.

[0041] The interior of the connecting rod 9 is hollow, and one end of the first pipe 10 passes through the bottom of the cleaning tank 6 and extends into the cleaning tank to inject water into the cleaning tank 6. The other end of the first pipe 10 passes through the hollow interior of the connecting rod 9 and into the hollow interior of the vertical rod 1 until it is connected to the water tank 18 located at the bottom of the vertical rod 1; a micro water pump can be used here to pump the water in the water tank 18 into the cleaning tank 6.

[0042] The side of the cleaning box 5 is provided with a rotating mechanism, and the rotating mechanism rotates to drive the cleaning box 5 to rotate. The rotating mechanism includes a main gear 1910 and a sub-gear 1920, and the sub-gear 1920 is sleeved on the outside of the cleaning box 5. The central connecting hole of the main gear 1910 is coaxially connected to the output shaft of the rotating motor 1930, and the rotating motor 1930 is arranged on the connecting rod 9. Here, the rotating mechanism uses the main gear and the sub-gear to realize the transmission, and the sub-gear is sleeved on the outside of the cleaning box 5, instead of directly using the rotating motor to drive the rotation of the cleaning box, because if the rotating motor is directly used, its output shaft must be connected to the most central position of the cleaning box, and considering that the cleaning box will rotate and rotate, the first pipe 10 must also be connected to the center of the bottom of the cleaning box, so that the self-rotation of the cleaning box will not affect the first pipe, otherwise the first pipe will also rotate with it, causing the self-rotation of the first pipe to be twisted off, and the first pipe 10 is connected to the bottom center of the cleaning box 5 through a bearing seal.

[0043] When the surface of the surveillance camera is adhered and wrapped by dust and dirt, the sliding ring 8 is used to move upward until the surveillance camera 4 is embedded in the cleaning groove 6, and the micro water pump is used to pump the water in the water tank 18 into the first pipe 10, and the water then falls from the first pipe 10 into the cleaning groove 6, and the cleaning sponge 7 absorbs the water. At this time, the rotating mechanism is started to rotate, driving the cleaning box 5 to rotate, specifically, the output shaft of the rotating motor 1930 rotates, driving the main gear to rotate, and then driving the secondary gear meshing with the main gear to rotate, and the water-absorbing cleaning sponge will rub against the surveillance camera, thereby scrubbing off the dust adhered to the surface of the surveillance camera, thereby cleaning the surveillance camera.

[0044] Considering that if the connecting rod 9 is of a fixed length and cannot be changed, such a long connecting rod is not only unsightly, but also affects the monitoring camera, the connecting rod 9 can be set as a hydraulic rod with a variable length, the fixed end of the hydraulic rod is connected to the vertical rod 1, and the telescopic end of the hydraulic rod is connected to the cleaning tank 6. Here, the connecting rod 9 is set as a hydraulic rod, and it is also considered that it is convenient to use a controller to control its automatic telescopic extension in the later stage.

[0045] In another embodiment, considering that sometimes the dust and stains on the surface of the surveillance camera are tightly attached, the cleaning effect may not be good if it is only by the cleaning sponge. In order to improve the cleaning effect, a preferred embodiment of the present invention also has the following design: the inner wall of the cleaning groove 6 is provided with a plurality of bristles 11 along its circumferential direction, each bristle 11 is provided along the depth direction of the cleaning groove 6, and the bristles 11 are inserted into the cleaning sponge 7. The cleaning sponge 7 and the bristles 11 are used for cleaning at the same time, the bristles with a certain hardness are used for preliminary cleaning, and the relatively soft cleaning sponge is used for all-round and careful cleaning. If only the bristles 11 with a certain hardness are used for cleaning, due to the gaps between the bristles, local positions may be missed, and the surface of the camera is also easily worn. Therefore, the bristles and the cleaning sponge are used synchronously in this embodiment.

[0046] In another embodiment, a water outlet is provided at the bottom of the cleaning tank 6, and a solenoid valve 12 is installed at the water outlet; the waste water after cleaning can be discharged by simply opening the solenoid valve 12.

[0047] A receiving tank 13 is also provided, the upper end of which is open and located below the solenoid valve. The receiving tank 13 is connected to the connecting rod 9 through a connecting mechanism 14. The bottom of the receiving tank 13 is connected to a recovery tank 16 through a second pipe 15. One end of the second pipe 15 is connected to the bottom of the cleaning tank 6, and the other end of the second pipe 15 passes through the hollow interior of the connecting rod 9 and enters the hollow interior of the vertical rod 1 until it is connected to the recovery tank 16 located at the bottom of the vertical rod 1. The recovery tank 16 is used to recover the waste water after cleaning.

[0048] Preferably, in the intelligent security monitoring device for the construction site, when the inner wall of the cleaning box 5 is a double-layer structure with a hollow structure, a heating plate is arranged inside the cleaning box to heat and dry the cleaning sponge after cleaning.

[0049] The following provides an automatic control method, wherein the hydraulic rod and the driving mechanism are connected to the controller;

[0050] The controller controls the driving mechanism to drive the sliding ring 8 to climb along the vertical rod 1 to a preset height, and then controls the telescopic end of the hydraulic rod to extend to a preset value. At this time, the cleaning groove 6 of the cleaning box 5 is located directly below the corresponding monitoring camera 4. The controller then controls the driving mechanism to drive the sliding ring 8 to climb along the vertical rod 1 to a preset height. At this time, the monitoring camera 4 is embedded in the cleaning groove 6.

[0051] Preferably, in the intelligent security monitoring device for the construction site, the controller is connected to the solenoid valve 12 to control the opening and closing of the solenoid valve 12 and the start-up duration.

[0052] Preferably, in the intelligent security monitoring device for construction sites, the upper end of the receiving tank 13 is upwardly connected to a truncated cone-shaped anti-spill plate 17 that is larger at the top and smaller at the bottom.

[0053] Considering the security issues of construction site monitoring, there are generally high requirements for the clarity of monitoring equipment. In order to facilitate subsequent playback and viewing, storage devices must be used to store monitoring videos. The high resolution of monitoring videos will inevitably lead to a large space occupied by monitoring videos. The limited space can store fewer videos, and sometimes construction sites will be shut down. At this time, there are actually no high requirements for the clarity of monitoring videos. If the highest definition video is still used, it will take up too much storage space, resulting in a waste of storage space. In order to avoid this problem, an implementation plan of the present invention has carried out a series of design optimizations, as follows: in the intelligent security monitoring device for the construction site, the monitoring camera 4 includes a control module, a camera module, a video storage and processing module, and a portrait recognition module, wherein,

[0054] The camera module captures the environment within the monitoring range in real time, and the portrait recognition module is connected to the camera module to identify whether there is a person in the video captured by the camera module; the camera module is also connected to the video storage processing module to process and store the video captured by the camera module, and the control module is respectively connected to the portrait recognition module and the video storage processing module; if the portrait recognition module recognizes that there is no person in the photos or videos captured by the camera module within a certain period of time, the control module controls the video storage processing module to reduce the pixel processing of the video captured by the camera module; if the portrait recognition module recognizes that there is a person in the photos or videos captured by the camera module, the control module controls the video storage processing module to increase the pixel processing of the video captured by the camera module.

[0055] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
