Description

Technical Field

[0001] This utility model relates to the field of construction engineering management technology, and more specifically to a construction site safety monitoring device. Background Technology

[0002] During the implementation of construction projects, it is necessary to supervise and manage the safety conditions of the construction site. This is usually achieved by installing surveillance cameras at the construction site, such as the monitoring devices with publication numbers CN218895184U and CN112147074A.

[0003] Construction sites generate a large amount of dust, which easily adheres to the surface of cameras and affects normal monitoring. Current technologies typically use methods such as blowing dust or wiping with water to remove dust. However, blowing dust is ineffective at removing dust from cameras; wiping with water increases the probability of water seeping into the camera, thus increasing the likelihood of damage, and also increases the workload of replacing and cleaning cleaning pads. Therefore, current technologies cannot fundamentally solve the problem of dust adhering to monitoring devices and affecting surveillance. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a construction site safety monitoring device. By forming an air curtain in front of the camera, the dust of the camera lens is isolated, thereby reducing the workload of personnel cleaning the camera. At the same time, the flowing air facilitates heat dissipation of the camera and extends the service life of the camera.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction site safety monitoring device, comprising a monitoring component and an installation component, wherein the monitoring component is used to monitor the construction site, and the installation component is located behind the monitoring component and is used to adjust the height of the monitoring component.

[0006] The monitoring component includes a camera and a hollow protective cover fixed to the outer top of the camera. The camera has an outer frame on its front side, which is fixed inside the hollow protective cover. The outer frame is hollow inside, and has an upper hole at the top of the inner end communicating with its inner cavity, and a lower hole at the bottom of the inner end communicating with its inner cavity. The upper and lower holes form an air curtain to block dust in front of the camera lens, that is, an invisible air barrier is formed in front of the camera lens. When dust particles move to the vicinity of the air curtain with the airflow, the trajectory of the dust particles will change due to the obstruction and disturbance of the airflow, making it difficult for them to pass through the air curtain, thereby achieving the effect of isolating dust.

[0007] Preferably, a driving component is fixedly provided at the bottom of the camera. The driving component includes a housing, and a partition is fixed inside the housing. The partition divides the interior of the housing into an air inlet chamber and an air outlet chamber distributed in front and behind. An opening is provided on the partition, and the air inlet chamber and the air outlet chamber are connected through the opening. A fan is fixed on the inner wall of the air outlet chamber.

[0008] Preferably, an air outlet hose is provided between the rear end of the outer shell and the rear end of the hollow protective cover, and the air outlet cavity is connected to the interior of the hollow protective cover through the air outlet hose; an air inlet hose is provided between the front end of the outer shell and the bottom of the outer frame, and the air inlet cavity is connected to the interior of the outer frame through the air inlet hose.

[0009] Preferably, the airflow blown by the fan flows through the hollow protective cover and is sprayed downward from the upper hole, and then enters the lower hole, so as to form an air curtain that flows from top to bottom between the upper and lower holes; the hollow protective cover is made of a heat-conducting plate, so that when the airflow passes through the hollow protective cover, it is convenient for the airflow to exchange heat with the camera, thereby facilitating the heat dissipation of the camera.

[0010] Preferably, the mounting assembly includes a mounting plate, in which a slider is slidably disposed; the mounting plate also includes a lead screw, on which a lead screw nut is connected, the lead screw and the lead screw nut both pass through one side of the slider, and the lead screw nut is fixed to the slider; the lead screw is driven to rotate by a motor fixed to the bottom end of the mounting plate.

[0011] Preferably, a bracket is fixed to the bottom of the outer shell, and the end of the bracket away from the outer shell is fixed to the front end of the slider via a connecting rod.

[0012] Preferably, the mounting plate has a groove at its front end, and the connecting rod passes through the groove and is slidably connected to the groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a fan to drive airflow, which forms an air curtain in front of the camera, creating an invisible air barrier in front of the camera lens. This effectively isolates dust, reduces dust adhesion to the camera lens, and thus reduces the workload of cleaning the camera. At the same time, the flowing airflow facilitates heat dissipation for the camera, extending its service life.

[0015] 2. The camera is moved up and down by a motor, which facilitates automatic adjustment of the camera's height, thus making the camera easier to install and maintain. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this utility model provides a construction site safety monitoring device, including a monitoring component 1. The monitoring component 1 includes a camera 11 and a hollow protective cover 12 fixed to the outer side of the top of the camera 11. The outer frame 13 is provided on the outer side of the front end of the camera 11. The outer frame 13 is fixed inside the hollow protective cover 12. The outer frame 13 does not obstruct the camera 11 from taking pictures. The outer frame 13 is hollow inside, and an upper hole 14 communicating with its inner cavity is opened at the top of the inner end of the outer frame 13. A lower hole 15 communicating with its inner cavity is opened at the bottom of the inner end of the outer frame 13.

[0026] The camera 11 is fixedly provided with a driving component 16 at its bottom end. The driving component 16 includes a housing 161. A partition 162 is fixed inside the housing 161, which divides the interior of the housing 161 into an air inlet chamber and an air outlet chamber distributed front and rear. An opening 164 is provided on the partition 162, through which the air inlet chamber and the air outlet chamber are connected. A fan 163 is fixed on the inner wall of the air outlet chamber. An air outlet hose 17 is provided between the rear end of the housing 161 and the rear end of the hollow protective cover 12, and the air outlet chamber is connected to the interior of the hollow protective cover 12 through the air outlet hose 17. An air inlet hose 18 is provided between the front end of the housing 161 and the bottom of the outer frame 13, and the air inlet chamber is connected to the interior of the outer frame 13 through the air inlet hose 18.

[0027] The airflow blown out by the fan 163 enters the hollow protective cover 12 through the outer shell 161 and the air outlet hose 17. The airflow is then sprayed downwards from the upper hole 14 and then drawn into the lower hole 15. It then enters the outer shell 161 through the air inlet hose 18. This cycle continues, and the airflow between the upper hole 14 and the lower hole 15 flows from top to bottom, thus forming an air curtain. The air curtain is located in front of the lens of the camera 11, forming an invisible air barrier. The dustproof principle of the air curtain is as follows: when dust particles move to the vicinity of the air curtain with the airflow, the movement trajectory of the dust particles will change due to the obstruction and disturbance of the airflow, making it difficult for them to pass through the air curtain. This achieves the effect of isolating dust and reducing the entry of dust and its adhesion to the lens of the camera 11.

[0028] Among them, the fan 163 uses the MZB3004T04 model, which is a miniature fan produced by Murata Manufacturing Co., Ltd. It can also be used as an air pump. It uses ceramic ultrasonic vibration as the driving source. Through the ultrasonic vibration of the ceramic substrate, the air is compressed and released, thereby realizing the suction and discharge of air, achieving the function of a fan or air pump. It features small size, light weight, quiet operation, and high pressure output.

[0029] In addition, the hollow protective cover 12 is made of a heat-conducting plate, which is made of high thermal conductivity materials such as copper and aluminum. When the airflow passes through the hollow protective cover 12, it facilitates the heat dissipation of the camera 11.

[0030] like Figure 5As shown, a mounting component 2 is provided on the rear side of the monitoring component 1. The mounting component 2 includes a mounting plate 21, a slider 22 is slidably mounted in the mounting plate 21, and a lead screw 23 is also provided in the mounting plate 21. A lead screw nut 24 is connected to the lead screw 23. Both the lead screw 23 and the lead screw nut 24 pass through one side of the slider 22, and the lead screw nut 24 is fixed to the slider 22. The lead screw 23 is driven to rotate by a motor 25 fixed to the bottom end of the mounting plate 21. The motor 25 is a micro motor from Zhaowei Electromechanical, with models including the ZWBPD series, such as ZWBPD006006, ZWBPD010010, ZWBPD016016, ZWBPD020020, ZWBPD022022, ZWBPD024024, and ZWBPD028028.

[0031] A bracket 19 is fixed at the bottom of the outer shell 161. The end of the bracket 19 away from the outer shell 161 is fixed to the front end of the slider 22 via a connecting rod 26. A sliding groove 27 is provided at the front end of the mounting plate 21. The connecting rod 26 passes through the sliding groove 27 and is slidably connected to the sliding groove 27.

[0032] The motor 25 drives the lead screw 23 to rotate, which in turn moves the lead screw nut 24 and the slider 22. This, in turn, moves the camera 11 up and down via the connecting rod 26 and the bracket 19, making it easier to automatically adjust the height of the camera 11 and thus facilitating its installation and maintenance.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
