Technical Field

[0001] This utility model relates to the field of network hard disk video recorder technology, and in particular to a heat-dissipating, dustproof network hard disk video recorder. Background Technology

[0002] A network video recorder (NVR) is a core device for network video surveillance, specifically designed to receive, store, and manage digital video signals transmitted from network cameras. It provides functions such as video preview, playback, remote access, and intelligent analysis. NVRs are a crucial component of modern security monitoring systems and are widely used in security monitoring, home care, traffic management, and industrial applications. They receive and store video data from network cameras and support local and remote preview and playback, as well as intelligent alarm linkage. NVRs are the core storage and management devices for high-definition network monitoring systems.

[0003] When workers need to store data, they input the data into the network video recorder (NVR) so that the NVR can store the data. However, existing NVRs typically rely on ventilation holes for natural heat dissipation during use. This causes the NVR to be affected by airflow during heat dissipation, and dust can enter the host unit, leading to heat dissipation problems during use. Utility Model Content

[0006] Preferably, a pull spring is fixedly connected between the guide rod and the guide block. The pull spring is located on one side of the slide rail and can cooperate with the guide rod and the guide block to restrict the sliding of the closed frame.

[0007] Preferably, the surface of the air duct is provided with a dustproof device, the dustproof device including a storage groove, the storage groove being opened on the surface of the air duct, the storage groove being located below the closed frame, the storage groove being able to cooperate with the air duct to achieve the purpose of storing the frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up a heat dissipation device, when the worker needs to dissipate heat from the network hard disk recorder, the worker pushes the closed frame while using the network hard disk recorder. The closed frame moves the slide rail, which is guided by the guide block. The slide rail slides on the surface of the air passage, and the closed frame opens the exhaust port. The closed frame pushes the support block and the guide rod, and the guide rod stretches the spring. The guide block guides the guide rod. When the inner side of the support block and the guide block abuts, the support block is magnetically attracted to the guide block, and the closed frame remains stationary. The driver is started, and the driver drives the fan blades inside the closed frame to rotate. The fan blades rotate and push the exhaust port. Air entering through the vent flows into the host unit. When the network video recorder is idle, the drive is shut off, pushing the sealing frame. The sealing frame moves the slide rail, which in turn moves the support block away from the guide block. Pulling the spring pulls the guide rod, which pushes the sealing frame, sealing the vent and preventing dust from entering the host unit. By incorporating a heat dissipation device, the network video recorder can be effectively cooled, avoiding the impact of airflow on its cooling process. This also prevents dust from entering the host unit and affecting the cooling of electrical components, thus reducing the risk of overheating issues during operation.

[0013] 2. In this utility model, by setting a dustproof device, when the operator needs to filter the air, the operator places the frame inside the storage slot. The frame drives the filter screen into the storage slot, and the frame drives the support bar. When the support bar abuts against the surface of the host, the operator inserts the threaded rod into the support bar. The threaded rod abuts against the threaded hole, and the threaded rod is rotated. The threaded rod is connected to the internal thread of the threaded hole. By setting a dustproof device, the operator can effectively filter the air and prevent the air from carrying dust into the host, thereby improving the dustproof performance of the network hard disk recorder.

[0024] Specifically, the support block 36 is fixedly connected to the surface of the slide 39, the support block 36 has magnetic force, the support block 36 is located on one side of the guide block 31, the surface of the support block 36 is fixedly connected to the guide rod 37, the guide rod 37 is slidably connected to the inside of the guide block 31, the support block 36 can cooperate with the slide 39 to achieve the purpose of fixing the support block 36, the support block 36 has magnetic force, and the guide rod 37 can cooperate with the support block 36 to achieve the purpose of fixing the guide rod 37.

[0025] Specifically, a pull spring 38 is fixedly connected between the guide rod 37 and the guide block 31, and the pull spring 38 is located on one side of the slide rail 39.

[0026] In this embodiment, the pull spring 38 can cooperate with the guide rod 37 and the guide block 31 to restrict the sliding of the closed frame 34.

[0027] In this embodiment: a dustproof device 4 is provided on the surface of the air duct 32. The dustproof device 4 includes a storage groove 46. The storage groove 46 is opened on the surface of the air duct 32 and is located below the closed frame 34. The storage groove 46 can cooperate with the air duct 32 to achieve the purpose of storing the frame 42.

[0028] Specifically, a frame 42 is placed inside the storage slot 46, and the frame 42 is located below the closed frame 34.

[0029] In this embodiment, the frame 42 can cooperate with the storage slot 46 to support the filter screen 41.

[0033] Working principle: By setting up heat dissipation device 3, when the operator needs to dissipate heat from the network video recorder, the operator pushes the closed frame 34, which drives the slide rail 39. The slide rail 39 is guided by the guide block 31 and slides on the surface of the air passage 32. The closed frame 34 opens the exhaust port 33, pushes the support block 36 and the guide rod 37, and the guide rod 37 stretches the spring 38. The guide block 31 guides the guide rod 37.

When the inner sides are in contact, the support block 36 is magnetically attached to the guide block 31, and the closed frame 34 remains stationary. The driver 35 is activated, which drives the fan blades inside the closed frame 34 to rotate. The rotating fan blades push the air entering from the exhaust port 33 into the interior of the host 1. When the network hard disk recorder is idle, the driver 35 is deactivated, pushing the closed frame 34. The closed frame 34 moves the slide rail 39, which in turn moves the support block 36 away from the guide block 31. The pull spring 38 pulls the guide rod 37, which pushes the closed frame 34. The enclosed frame 34 seals the exhaust port 33, preventing dust from entering the interior of the host unit 1. The heat dissipation device 3 effectively cools the network video recorder, preventing airflow from affecting its cooling process and blocking dust from entering the host unit 1 and affecting the heat dissipation of electrical components. This reduces the risk of overheating during operation. Furthermore, the dustproof device 4 allows for air filtration. When the operator needs to filter the air, the frame 42 is placed inside the storage slot 46, causing the filter 41 to enter. The frame 42 then moves the support bar 43. When the support bar 43 abuts against the surface of the host unit 1, the operator inserts the threaded rod 44 into the support bar 43, where it abuts against the threaded hole 45. Rotating the threaded rod 44 connects it to the internal thread of the threaded hole 45. The dustproof device 4 effectively facilitates air filtration, preventing dust from entering the host unit 1 and improving the network video recorder's dust resistance.
