Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch technology, specifically a 24-port PoE switch for video surveillance. Background Technology
[0002] Video surveillance is a crucial component of security systems. Traditional surveillance systems consist of front-end cameras, transmission cables, and a video monitoring platform. Communication between video surveillance terminals, resource sharing within the network, and remote monitoring often require switches. Ethernet switches, also known as PoE switches, are switches that transmit data based on Ethernet. Ethernet uses a shared bus transmission medium in local area networks (LANs). The structure of an Ethernet switch is such that each port is directly connected to a host and typically operates in full-duplex mode. A switch can simultaneously connect many pairs of ports, allowing each pair of communicating hosts to transmit data without collisions, as if they had exclusive access to the communication medium.
[0003] Because video surveillance requires connecting many devices to the switch, the switch temperature is high during use, requiring increased power to improve heat dissipation. This easily leads to dust accumulating on the switch's ventilation holes. Since the switch casing is fixed with nuts, cleaning the dust inside the switch is very troublesome. Long-term neglect can easily clog the ventilation holes, affecting heat dissipation. At the same time, excessive dust can affect the normal operation of the switch. Utility Model Content
[0004] The purpose of this utility model is to provide a solution to the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dedicated 24-port PoE switch for video surveillance, comprising a switch body, the switch body comprising a switch housing and an internal circuit board, the switch housing being provided with 24 network cable interfaces and a power interface, the 24 network cable interfaces and the power interface being connected to the internal circuit board via cables, a heat dissipation hole being provided on one side of the switch housing, a fan being provided on the internal circuit board corresponding to the position of the heat dissipation hole, a detachable filter mechanism being provided on the side of the switch housing located at the heat dissipation hole, the detachable filter mechanism comprising a mounting slot and a mounting plate, the mounting slot being located on the switch housing, the mounting plate being movably installed in the mounting slot, a filter slot being provided on the mounting plate, and a filter being installed on the filter slot.
[0006] Preferably, the bottom of the mounting groove is provided with a movable rod, and at least two sets of the movable rod are provided.
[0007] Preferably, a spring is connected to the bottom of the movable rod, and the other end of the spring is connected to the bottom of the switch housing.
[0008] Preferably, the mounting slot has blocking blocks on both sides of the slot opening, a slider at the bottom of the blocking block, and a sliding groove on the switch housing. The blocking block is installed in the sliding groove of the switch housing by means of the slider.
[0009] Preferably, the mounting plate has mating grooves on both sides of its top.
[0010] Preferably, the surface of the blocking block is provided with anti-slip texture.
[0011] Preferably, the filter is located on one side of the heat dissipation holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention features a detachable filter mechanism inside the switch housing, located on the side of the heat dissipation holes. When the switch is in operation, dust can be adsorbed onto the filter. By replacing the filter, excessive dust accumulation can be prevented, thus effectively isolating external dust and preventing it from affecting the operation of the internal circuit board. At the same time, it prevents the heat dissipation holes from being blocked, which would affect the heat dissipation effect of the switch. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution for a dedicated 24-port PoE switch for video surveillance: it includes a switch body 1, which consists of a switch housing 2 and an internal circuit board 3. The switch housing 2 is provided with a 24-port network cable interface 4 and a power interface 5. The 24-port network cable interface 4 and the power interface 5 are connected to the internal circuit board 3 via cables. A heat dissipation hole 6 is provided on one side of the switch housing 2. A fan corresponding to the position of the heat dissipation hole 6 is provided on the internal circuit board 3. A detachable filter mechanism 7 is provided on the side of the switch housing 2 located at the heat dissipation hole 6. The detachable filter mechanism 7 includes a mounting groove 8 and a mounting plate 9. The mounting groove 8 is located on the switch housing 2, and the mounting plate 9 is movably installed in the mounting groove 8. A filter groove 10 is provided on the mounting plate 9, and a filter 11 is installed on the filter groove 10. The filter 11 is located on one side of the heat dissipation hole 6.
[0022] Combination Figure 3 As shown, a movable rod 12 is provided at the bottom of the mounting slot 8. At least two sets of movable rods 12 are provided. A spring 13 is connected to the bottom of the movable rod 12. The other end of the spring 13 is connected to the bottom of the switch housing 2. The movable rod 12 can push the mounting plate 9 out of the mounting slot 8 under the action of the spring.
[0023] Combination Figure 3 As shown, blocking blocks 14 are provided on both sides of the groove opening of the mounting groove 8, and sliders 16 are provided at the bottom of the blocking blocks 14. A sliding groove 15 is provided on the switch housing 2. The blocking blocks 14 are installed in the sliding groove 15 of the switch housing 2 through the sliders 16. The mounting plate 9 has mating grooves 17 on both sides of the top. The blocking blocks 14 are used to fix the mounting plate 9 so that the mounting plate 9 is fixed in the mounting groove 8. The mating grooves 17 can cooperate with the blocking blocks 14 to make the surface of the mounting plate 9 flat.
[0024] Specifically, the surface of the blocking block 14 is provided with anti-slip texture, which can improve friction.
[0025] Working principle: When using this utility model, push the blocking block 14 at the opening of the mounting slot 8 outward. At this time, the mounting plate 9 is released from the constraint of the blocking block 14 and pushed out by the spring 13. The operator can replace the filter screen 11 on the mounting plate 9. After replacing the filter screen 11, push the mounting plate 9 into the mounting slot 8 and bring the blocking block 14 close to the slide groove 15 to complete the replacement of the filter screen 11. By setting a detachable filter screen mechanism 7 on the side of the heat dissipation hole 6 on the switch housing 2, dust can be adsorbed on the filter screen 11 when the switch is working. By replacing the filter screen 11, excessive dust accumulation is prevented, thereby effectively isolating external dust and preventing dust from affecting the operation of the internal circuit board 3. At the same time, it prevents the heat dissipation hole 6 from being blocked and affecting the heat dissipation effect of the switch. It has the advantages of simple structure, convenient use and good performance.
