Description

Technical Field

[0001] The present invention relates to the technical field of university education and teaching, and in particular to a university education and teaching management information system. Background Art

[0002] The college education and teaching management information system is responsible for managing the education and teaching information of colleges and universities. In the management process, it is often necessary to collect information in order to understand the specific learning situation of students. At this time, monitoring devices are usually used to collect video information.

[0003] In response to the existing problems of dust pollution on the monitoring mirror and the key components inside the monitor body being easily aged due to high temperature, the patent with the publication number "CN114928967A" proposes a university education and teaching management information system, which mainly designs a cooling mechanism and a brush to solve the problems of monitoring surface pollution and high temperature aging of monitoring components. However, in this scheme, only a brush is used to clean the lens surface. Due to the factors of chalk dust in the school and frequent movement of people, it is difficult to wipe the lens surface clean by brushing alone. Dust easily sticks to the lens surface, causing the lens to be blurred and the monitoring effect is poor. Secondly, in this scheme, the fan is used to blow through the circulation duct to cool the components. This non-direct contact cooling method has a poor cooling effect. In addition, there is no linkage between the cleaning mechanism and the cooling mechanism. The operator needs to control the two separately to work, which is also troublesome. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a university education and teaching management information system.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A university education and teaching management information system comprises a monitoring housing and a camera installed inside the monitoring housing through a mounting plate, a fixing structure is arranged at the bottom of the monitoring housing, and a cooling component, a liquid flow component, a heat dissipation component, a wiping component and a spraying component are installed on the monitoring housing. The cooling component is composed of a serpentine cooling pipe and heat-conducting fins, and is used to reduce the temperature of the camera when it is working. The serpentine cooling pipe is fixedly installed under the mounting plate, and a plurality of heat-conducting fins are fixed at the bottom of the camera and extend to the bottom of the mounting plate to fit with the serpentine cooling pipe; The liquid flow assembly is composed of a coolant tank, a pump pipe and a return pipe, and is used to circulate the coolant; The heat dissipation assembly is composed of heat dissipation fins, a dual-axis motor and a heat dissipation fan, and is used to keep the coolant at a low temperature; The wiping assembly is composed of a strip-shaped cleaning brush, and the strip-shaped cleaning brush is arranged above the camera lens; The spray assembly is composed of a plurality of nozzles, a guide hole is provided at the upper end of the monitoring housing, and the plurality of nozzles are arranged at the bottom of the upper end of the monitoring housing and are connected to the guide hole; The heat dissipation component is connected to the wiping component through a transmission mechanism, and the transmission mechanism is connected to the spraying mechanism through a pumping mechanism.

[0006] Preferably, a plurality of the heat dissipation fins are inserted at the upper end of the coolant tank and are in contact with the coolant, the dual-axis motor is fixedly mounted at the upper end of the coolant storage tank via a fixing plate, and the heat dissipation fan is fixedly mounted on an output shaft of the dual-axis motor.

[0007] Preferably, the coolant tank is fixedly mounted on the side wall of the monitoring housing, the pump liquid pipe is connected between the coolant tank and the liquid inlet end of the serpentine cooling pipe and is equipped with a liquid pump, and the reflux pipe is connected between the coolant tank and the liquid outlet end of the serpentine cooling pipe.

[0008] Preferably, the transmission mechanism includes an incomplete gear, a rack, a connecting rod and a return spring, the incomplete gear is fixedly connected to the output shaft of the dual-axis motor, the rack is slidably connected to the side wall of the monitoring shell and meshes with the incomplete gear, a baffle is fixedly installed on the side wall of the monitoring shell, the connecting rod is fixed to the lower end of the rack and is slidably connected to the baffle, the return spring is arranged on the outside of the connecting rod and is elastically connected between the baffle and the rack, and the rack is fixedly connected to the cleaning brush through a cross bar.

[0009] Preferably, the pumping mechanism includes a cleaning liquid tank, a pump cylinder and a piston. The cleaning liquid tank is fixedly mounted on the side wall of the monitoring shell and stores cleaning liquid. The pump cylinder is fixed at the lower end of the cooling liquid tank. The piston is sealingly and slidingly connected between the inner walls of the pump cylinder and is fixedly connected to the connecting rod. The pump cylinder is connected to the cleaning liquid tank through a liquid inlet pipe, and the pump cylinder is connected to the guide hole through a liquid outlet pipe.

[0010] Preferably, a one-way valve is installed in the liquid inlet pipe, which only allows the cleaning liquid to flow from the cleaning liquid tank to the pump fluid cylinder, and a one-way valve is installed in the liquid outlet pipe, which only allows the cleaning liquid to flow from the pump fluid cylinder to the guide hole.

[0011] Preferably, the cleaning brush surface is made of elastic rubber material and is in close contact with the camera.

[0012] Preferably, a pair of isolation plates are symmetrically fixedly arranged in the coolant tank, each of the pair of isolation plates is provided with a liquid outlet hole, and the plurality of heat dissipation fins are located in the middle of the pair of isolation plates.

[0013] The present invention has the following beneficial effects: 1. The cooling component of the present invention can directly cool the camera through the cooperation of the serpentine cooling pipe and the heat-conducting fins. Compared with the air-cooling cooling method without direct contact in the prior art, the cooling effect is significantly improved. The serpentine cooling pipe surrounds the bottom of the camera, and the heat-conducting fins are tightly attached to the bottom of the camera and extend to the cooling pipe, so that the heat can be quickly transferred to the cooling pipe, and the heat is taken away by the circulation of the coolant, which effectively reduces the working temperature of the camera, greatly slows down the aging speed of key components due to high temperature, prolongs the service life of the equipment, and ensures that the monitoring system can operate stably for a long time. In addition, the setting of the heat dissipation component can keep the coolant at a low temperature through the heat dissipation fins, and has a good cooling effect; 2. The system is not only equipped with a strip cleaning brush, but also equipped with a spraying component. During the cleaning process, multiple nozzles of the spraying component will spray cleaning liquid onto the camera lens to soften and dilute the dust and other dirt on the lens surface, and then the strip cleaning brush will wipe it. Compared with the existing method of wiping with a brush, this method of spraying first and then wiping can more thoroughly remove the dirt on the lens surface and effectively avoid the problem of blurring caused by dust sticking to the lens, thereby significantly improving the monitoring effect and providing clearer and more accurate video information for college education and teaching management; 3. In the present invention, the heat dissipation component, the wiping component and the spraying component are linked through the transmission mechanism and the pumping mechanism. When the dual-axis motor of the heat dissipation component is started, the cleaning brush of the wiping component is driven to reciprocate through the transmission mechanism. At the same time, the pumping mechanism works during the transmission process to pump out the cleaning liquid in the cleaning liquid tank and spray it onto the lens through the spraying component. This linkage design eliminates the need for the operator to control each component separately. The operator only needs to start the heat dissipation component to achieve the coordinated work of the cleaning and cooling functions, which greatly simplifies the operation process and improves the intelligence and utilization efficiency of the system.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-6 A university education and teaching management information system includes a monitoring housing 1 and a camera 2 installed inside the monitoring housing 1 through a mounting plate 22.

[0019] The heat dissipation assembly consists of heat dissipation fins 10, a dual-axis motor 14 and a heat dissipation fan 13, which are used to keep the coolant at a low temperature. Multiple heat dissipation fins 10 are inserted at the upper end of the coolant tank 5 and are in contact with the coolant. The dual-axis motor 14 is fixedly installed at the upper end of the coolant storage tank 5 through a fixing plate 15, and the heat dissipation fan 13 is fixedly installed on an output shaft of the dual-axis motor 14.

[0020] The wiping assembly is composed of a strip cleaning brush 4, which is arranged above the lens of the camera 2; The spray assembly is composed of a plurality of nozzles 3. A guide hole is provided at the upper end of the monitoring housing 1. The plurality of nozzles 3 are all arranged at the bottom of the upper end of the monitoring housing 1 and are all connected to the guide hole. The heat dissipation component is connected with the wiping component through a transmission mechanism, and the transmission mechanism is connected with the spraying mechanism through a pumping mechanism.

[0021] The transmission mechanism includes an incomplete gear 16, a rack 17, a connecting rod 18 and a reset spring 19. The incomplete gear 16 is fixedly connected to the output shaft of the dual-axis motor 14. The rack 17 is slidably connected to the side wall of the monitoring housing 1 and meshes with the incomplete gear 16. A baffle 25 is fixedly installed on the side wall of the monitoring housing 1. The connecting rod 18 is fixed to the lower end of the rack 17 and is slidably connected to the baffle 25. The reset spring 19 is arranged on the outside of the connecting rod 18 and is elastically connected between the baffle 25 and the rack 17. The rack 17 is fixedly connected to the cleaning brush 4 through a cross bar 27.

[0022] The pump mechanism comprises a cleaning liquid tank 20, a pump fluid cylinder 8 and a piston 26, wherein the cleaning liquid tank 20 is fixedly mounted on the side wall of the monitoring housing 1 and is stored with cleaning liquid, the pump fluid cylinder 8 is fixed at the lower end of the cooling liquid tank 5, the piston 26 is sealingly and slidably connected between the inner walls of the pump fluid cylinder 8 and is fixedly connected with the connecting rod 18, the pump fluid cylinder 8 is communicated with the cleaning liquid tank 20 through the liquid inlet pipe 11, and the pump fluid cylinder 8 is communicated with the guide hole through the liquid outlet pipe 12. A one-way valve that only allows cleaning liquid to flow from the cleaning liquid tank 20 to the pump fluid cylinder 8 is installed in the liquid inlet pipe 11, and a one-way valve that only allows cleaning liquid to flow from the pump fluid cylinder 8 to the guide hole is installed in the liquid outlet pipe 12.

[0023] The brush surface of the cleaning brush 4 is made of elastic rubber material and keeps in close contact with the camera 2. A pair of isolation plates 28 are symmetrically fixed in the coolant tank 5. Liquid outlet holes are opened on the pair of isolation plates 28, and multiple heat dissipation fins 10 are located in the middle of the pair of isolation plates 28.

[0024] In the present invention, after the system is turned on, the monitoring housing 1 is firmly installed at a designated position through the fixing structure 9 at the bottom, and the camera 2 is inside the monitoring housing 1 and fixed by the mounting plate 22, ready for video information collection.

[0025] The camera 2 generates heat during operation. The heat-conducting fins 23 fixed at the bottom of the camera 2 conduct the heat generated by the camera and extend to the bottom of the mounting plate 22 to fit the serpentine cooling pipe 24, transferring the heat to the serpentine cooling pipe 24. The liquid flow component starts to work, the liquid pump 21 starts, and the coolant in the coolant tank 5 is pumped into the liquid inlet end of the serpentine cooling pipe 24 through the pump liquid pipe 6. The coolant flows in the serpentine cooling pipe 24, absorbing the heat from the outside of the pipe. The heated coolant flows back to the coolant tank 5 through the return pipe 7, completing the circulation of the coolant.

[0026] The heat dissipation components work together, and the multiple heat dissipation fins 10 inserted at the upper end of the coolant tank 5 are in contact with the coolant to absorb the heat in the coolant. The dual-axis motor 14 is fixed to the upper end of the coolant tank 5 through the fixing plate 15, and its output shaft drives the cooling fan 13 to rotate, and the heat dissipation fins 10 are air-cooled to dissipate heat, so that the coolant remains at a low temperature so that it can continue to participate in the circulation to cool the camera. At the same time, a pair of symmetrically arranged isolation plates 28 in the coolant tank 5 are provided with liquid outlet holes, which play a certain guiding and buffering role in the flow of the coolant. The multiple heat dissipation fins 10 are located in the middle of the pair of isolation plates 28, which can dissipate heat from the coolant more effectively.

[0027] When the dual-axis motor 14 of the heat dissipation assembly is running, the incomplete gear 16 fixedly connected to the output shaft of the dual-axis motor 14 rotates accordingly. The incomplete gear 16 meshes with the rack 17 slidably connected to the side wall of the monitoring housing 1. Under the rotation of the incomplete gear 16, the rack 17 slides up and down along the side wall of the monitoring housing 1. The baffle 25 fixedly installed on the side wall of the monitoring housing 1 limits the movement of the connecting rod 18. The connecting rod 18 is fixed to the lower end of the rack 17 and is slidably connected to the baffle 25. The reset spring 19 is sleeved on the outside of the connecting rod 18 and elastically connected between the baffle 25 and the rack 17. When the incomplete gear 16 rotates to make the rack 17 move downward, the reset spring 19 is stretched; when the incomplete gear 16 is out of mesh with the rack 17, the reset spring 19 contracts, driving the rack 17 to reset upward. The rack 17 is fixedly connected to the cleaning brush 4 through the crossbar 27, so that the cleaning brush 4 can wipe back and forth above the lens of the camera 2.

[0028] During the up and down sliding of the rack 17, the piston 26 fixedly connected thereto slides in a sealed manner between the inner walls of the pump fluid cylinder 8. When the piston 26 moves downward, a negative pressure is formed in the pump fluid cylinder 8, the one-way valve in the liquid inlet pipe 11 opens, and the cleaning liquid in the cleaning liquid box 20 enters the pump fluid cylinder 8 through the liquid inlet pipe 11 under the action of atmospheric pressure; when the piston 26 moves upward, the one-way valve in the liquid outlet pipe 12 opens, and the cleaning liquid in the pump fluid cylinder 8 is pressed into the guide hole through the liquid outlet pipe 12, and finally sprayed from the multiple nozzles 3 at the bottom of the upper end of the monitoring housing 1, and sprinkled on the lens of the camera 2. In this way, before the cleaning brush 4 wipes, the dirt on the surface of the lens is softened and diluted by the cleaning liquid to improve the cleaning effect. In the whole process, the brush surface of the cleaning brush 4 is made of elastic rubber material, and it always keeps a fitting state with the camera 2 to ensure the tightness and effectiveness of wiping.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
