Description

Technical Field

[0001] The present invention relates to the technical field of security monitoring, in particular to a campus security monitoring device. Background Art

[0002] Campus security monitoring refers to the real-time monitoring and recording of personnel activities, facility status and surrounding environment on campus through technical means to prevent safety accidents, maintain campus order and improve emergency response capabilities. Its core goal is to build a comprehensive, responsive and intelligently linked security protection system to ensure the personal and property safety of teachers and students and the normal development of teaching activities. A large number of cameras are used to comprehensively monitor the campus to prevent the occurrence of danger.

[0003] For example, a day and night filter switching surveillance camera with publication number CN207612338U is provided with a photosensor, a hydraulic cylinder and a mounting bracket. The photosensor detects the surrounding light, switches the filter according to the illumination, adjusts the filtering effect of the camera during the day and at night, and improves the surveillance camera effect. However, the illumination at different times in the lighting environment varies greatly due to the influence of the angle of sunlight, so the clarity of the shooting picture can only be slightly improved by switching the dual filter lens, and the surveillance picture will still be overexposed.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figures 1 to 7 , the present invention provides the following technical solutions: Embodiment 1: A campus security monitoring device includes a housing 1, a camera assembly 2 is provided inside the housing 1, a fixing assembly 3 is provided on the surface of the camera assembly 2, and a pushing assembly 4 is provided at the lower end of the housing 1; The camera assembly 2 includes a slide 21, which is movably sleeved on the inner wall of the casing 1. A camera 22 is fixedly connected to the inside of the slide 21, a fixing plate 23 is fixedly sleeved on the inner wall of the slide 21, a cylinder 24 is clamped on the inner wall of the opening of the slide 21, an arc hole 25 is provided on the outer circular side wall of the cylinder 24, a plurality of arc grooves 26 are provided on the inner wall of the lower end of the cylinder 24, a slide 27 is slidably connected to the inside of the arc groove 26, a fan-shaped plate 28 is fixedly connected to the upper end of the slide 27, two circular holes 29 are symmetrically provided on the surface of the fan-shaped plate 28, a filter lens 210 is embedded in one of the circular holes 29, an air pump 211 is fixedly connected to the lower end of the cylinder 24, a plurality of hoses 212 are connected to both ends of the air pump 211, the other end of the hose 212 is connected to the control valve 213, and an infrared night vision light 214 is fixedly connected to the other side of the cylinder 24.

[0019] The control valve 213 is mounted on the outer wall of the cylinder 24 . The gas outlet end of the control valve 213 is connected to the interior of the arc-shaped groove 26 , and the gas is input into the arc-shaped groove 26 through the control valve 213 .

[0020] When in use, first, the opening and closing of the control valve 213 is controlled by the photosensitive controller, and the air pump 211 is started to absorb external gas and then compress it. The gas is input into the control valve 213 through the hose 212, and then the gas is input into the arc groove 26 through the control valve 213. When the compressed gas contacts the slide plate 27, a large amount of thrust is generated. The thrust generated by the compressed gas pushes the slide plate 27 in the arc groove 26 to rotate. The slide plate 27 and the arc groove 26 have an interference fit. Without external force, the slide plate 27 cannot slide. The slide plate 27 drives the fan plate 28 to rotate inside the arc hole 25. The fan plate 28 The upper surface of the fan-shaped plate 28 and the lower surface of the arc block 32 are arranged around the same center of a circle, and the lower surface of the fan-shaped plate 28 and the lower end inner wall of the arc hole 25 are arranged around the same center of a circle. The upper and lower end surfaces of the fan-shaped plate 28 are arranged around the same center of a circle, so that the fan-shaped plate 28 can slide stably between the arc hole 25 and the arc block 32. When the fan-shaped plate 28 moves, the circular hole 29 on the surface moves, and the circular hole drives the filter lens 210 to move. When the fan-shaped plate 28 is respectively stuck on both sides of the arc hole 25, the two circular holes 29 can correspond to the camera head of the camera 22, so that multiple filter lenses 2 can be controlled. 10 are used in a superimposed manner. The number of control valves 213 on both sides of the sector plates 28 is controlled to be activated according to the light intensity sensed by the light-sensitive controller. When the light intensity is high, the sector plates 28 are controlled to rotate to the left so that the multiple filter lenses 210 correspond to the camera 22. When the light intensity is low, the sector plates 28 are controlled to rotate to the right so that the multiple circular holes 210 correspond to the camera 22. The number of filter lenses 210 corresponding to the camera 22 is controlled. By changing the number of superimposed filter lenses 210, the filter degree at the lens is controlled. In this way, the light entering the camera can be more accurately controlled. The light at the lens of the camera 22 is prevented from being overexposed, which greatly improves the clarity of the captured image. The air pump 211 is used as a power source to provide sliding power for the slide 27. A single air pump 211 can provide power for multiple channels, effectively reducing power costs. The air pump 211 and the control valve 213 are small in size, and multiple control valves 213 can be set in the same space, which is convenient for providing space for the filter lens 210. The power provided by the air pump 211 is gas pressure, and the power release speed is fast and the power is sufficient, which can stably push the slide 27 to slide.

[0021] Embodiment 2: The technical solution that distinguishes this embodiment from that of Embodiment 1 includes: the fixing component 3 includes an arc opening 31, the arc opening 31 is opened at the upper end of the cylinder 24, the inside of the arc opening 31 is clamped with an arc block 32, the upper surface of the arc opening 31 is provided with four clamping interfaces 33, four clamping blocks 34 are fixedly connected to the lower surface of the arc block 32, the clamping blocks 34 are clamped inside the clamping interfaces 33, four arc plates 35 are clamped on the outer walls of the cylinder 24 and the arc block 32, threaded holes 36 are opened on the surface of the arc plates 35, the internal threads of the threaded holes 36 are connected with bolts 37, slots 38 are opened on the outer walls of the cylinder 24 and the arc block 32, and the bolts 37 are inserted inside the slots 38.

[0022] The lower surface of the arc block 32 matches the upper surface of the sector plate 28 , and the inner wall of the cylinder 24 matches the lower surface of the sector plate 28 , so that the sector plate 28 can slide stably between the arc block 32 and the sector plate 28 .

[0023] A fixing block 39 is fixedly connected to the outer wall of the housing 1 , and the fixing block 39 is installed on the outer wall of the lower end of the air pump 211 . The air pump 211 is fixed by the fixing block 39 to prevent the air pump 211 from loosening.

[0024] The arc plate 35 is fixedly connected to the side wall of the fixed plate 23. The length of the arc plate 35 is the same as the length of the cylinder 24, so that the arc plate 35 completely covers the cylinder 24 to prevent the lens from falling off.

[0025] When in use, first clamp the arc block 32 on the arc opening 31, so that the clamping block 34 is clamped inside the clamping interface 33, then clamp the arc block 32 and the cylinder 24 into the arc plate 35, turn the bolt 37 into the threaded hole 36, and fix the arc plate 35 to the arc block 32 and the cylinder 24 by inserting the bolt 37 into the slot 38, thereby stably fixing the lens inside the slide 21.

[0027] When in use, first push the rubber rotating strip 45 downward to rotate it so that the rubber rotating strip 45 moves away from the surface of the trapezoidal block 47. The end of the trapezoidal block 47 that contacts the rubber rotating strip 45 is protruded so that the trapezoidal block 47 and the rubber rotating strip 45 can be engaged with each other. Pushing the rubber rotating strip 45 downward can release the fixation of the trapezoidal block 47 on the rubber rotating strip 45, so that the slider 41 moves out of the fixing groove 46, and then push the slider 41 to slide in the slide groove 42. The slider 41 can drive the slide cylinder 21 to slide out of the casing 1, making it convenient to repair and replace the entire camera assembly 2.
