Technical Field

[0001] The utility model relates to the field of monitoring terminals, in particular to an intelligent cabinet for police equipment with a high heat-insulating protective plate. Background Art

[0002] With the rapid development of science and technology, people are enjoying the sense of security brought by security monitoring. The field of security monitoring has the logical requirements of pre-prevention, in-process response, and post-event investigation. Artificial intelligence can provide a new solution to this problem. In recent years, with the continuous expansion of urban areas, the importance of urban public security has become increasingly prominent. The country is carrying out large-scale construction of public security video surveillance projects in cities and towns, giving birth to many video surveillance points. At present, the growth rate of domestic public security police force is far from meeting actual needs, and artificial intelligence is extremely important. Therefore, there are many police equipment smart cabinets on the market for the automation and information management of monitoring systems.

[0003] The existing police monitoring cabinet has a heat dissipation bin on the top of the cabinet that is connected to the inside of the cabinet, and the heat inside the cabinet is dissipated by a fan. However, in order to consider the waterproof requirements, the heat dissipation bin on the top of the existing monitoring cabinet only has heat dissipation holes below the heat dissipation bin. This results in the heat inside the cabinet not being able to be discharged upward well and easily accumulating in the heat dissipation bin. Utility Model Content

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides an intelligent cabinet for police equipment with a high thermal insulation protective plate, so as to solve the problem proposed in the background technology that the heat dissipation bin on the top of the existing monitoring cabinet is only provided with heat dissipation holes below the heat dissipation bin in order to consider the waterproof requirement, which results in that the heat inside the box cannot be well discharged upward and is easily accumulated in the heat dissipation bin.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: an intelligent cabinet for police equipment with a high thermal insulation protective plate, comprising a box body and a heat dissipation bin fixed on the top of the box body, a plurality of lower heat dissipation holes are opened between the heat dissipation bin and the top of the box body, and a heat dissipation fan covering the lower heat dissipation holes is fixed inside the heat dissipation bin, a plurality of upper heat dissipation holes are opened on the top of the heat dissipation bin, a baffle located between the upper heat dissipation holes and the heat dissipation fan is fixed on the top of the heat dissipation bin, and a concave air guide cover located on the periphery of the baffle is fixed, when the heat dissipation fan blows the hot air flow to the bottom surface of the baffle, the hot air flow can pass through the guide of the air guide cover to flow to the top of the baffle, and finally to the upper heat dissipation holes.

[0006] Preferably, an intelligent reclosing module near the top and a plurality of sockets are fixed inside the box.

[0007] Preferably, a power lightning protection module, a data acquisition module, a network transmission module, an intelligent power module and an intelligent control module which together form a rectangular array are fixed inside the box.

[0008] Preferably, the box body is hinged with a box door, and a micro switch is provided at the front opening of the box body, and the micro switch can be triggered when the box door and the box body are closed.

[0009] Preferably, the bottom area of ​​the heat dissipation bin is larger than the top area of ​​the box body, and a plurality of external heat dissipation holes are formed through the bottom of the heat dissipation bin near the periphery.

[0010] Preferably, a conical water deflector is fixed to the bottom of the heat dissipation bin, and the water deflector is arranged on the periphery of the heat dissipation fan and is higher than the heat dissipation fan. The outer bottom of the water deflector is in contact with the external heat dissipation hole, and the upper opening area of ​​the water deflector is smaller than the area of ​​the baffle and is located directly below the baffle. The bottom surface of the baffle is provided with a recessed portion whose area is larger than the upper opening area of ​​the water deflector.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The utility model has a heat dissipation bin on the top of the box, and the heat dissipation bin and the top of the box are provided with a through lower heat dissipation hole, and a heat dissipation fan covering the lower heat dissipation hole is fixed in the heat dissipation bin, and the wind direction of the heat dissipation fan faces upward, and an upper heat dissipation hole located directly above the heat dissipation fan is opened on the top of the heat dissipation bin. For waterproofing, a baffle located between the upper heat dissipation hole and the heat dissipation fan is fixed inside the heat dissipation bin, and a concave air guide cover is fixed around the baffle. When the heat dissipation fan blows the heat inside the box to the baffle, the hot air flow will diffuse around the baffle and contact with the concave surface of the air guide cover. The concave surface will guide the hot air flow to the top of the baffle and discharge it from the upper heat dissipation hole to avoid heat accumulation in the heat dissipation chamber. An external heat dissipation hole that does not penetrate the box body is opened on the periphery of the bottom of the heat dissipation chamber, and a conical water guide plate that is covered on the periphery of the heat dissipation fan is fixed inside the heat dissipation chamber. When water seeps from the upper heat dissipation hole, the water will drip from around the baffle to the outer surface of the conical water guide cover. Since its outer surface is an inclined surface, the water will be guided to the external heat dissipation hole and discharged from the heat dissipation chamber. The design of water entering the heat dissipation chamber will not only prevent the water from entering the box body, but also take away some heat to further dissipate heat.

[0013] 2. The practical box is made of a protective plate with a thickness of ≥1.2mm and a galvanized sheet sprayed with plastic. The box size is ≥400 width * 550 height * 250 depth mm; the operating temperature range is -40℃~+85℃, and the heat insulation effect is good and can effectively prevent direct sunlight. When used outdoors, it can effectively reduce the impact of outdoor high temperature on the internal module unit. Combined with the structure of the above-mentioned heat dissipation warehouse, it can greatly improve the working efficiency and protection ability of the box. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The micro switch 4 is used to detect the opening and closing state of the door 3 for alarm.

[0045] In this embodiment, specifically, the bottom area of ​​the heat dissipation bin 2 is larger than the top area of ​​the box body 1, and a plurality of external heat dissipation holes 17 are formed through the bottom of the heat dissipation bin 2 near the periphery;

[0047] In this embodiment, specifically, a conical water guide cover 13 is fixed to the bottom of the heat dissipation bin 2, and the water guide cover 13 is arranged on the periphery of the heat dissipation fan 12 and is higher than the heat dissipation fan 12.

[0049] Working principle: When the heat dissipation fan 12 is started, the heat inside the box body 1 is blown upward through the penetration of the lower heat dissipation hole 11, and the hot air flow first contacts the bottom surface of the baffle 14, and then diffuses outward after contacting the bottom surface of the baffle 14. After continuing to diffuse, it contacts the air guide cover 15. Since the inner ring surface of the air guide cover 15 is concave, the hot air flow will be guided to the top of the baffle 14, and finally pass through the upper heat dissipation hole 16 to be discharged from the heat dissipation chamber 2; when the upper heat dissipation hole 16 penetrates into the water flow, the water flow first drips on the top surface of the baffle 14, and then flows to the outer edge of the baffle 14. Since the bottom surface of the baffle 14 is a recessed part, the water flow directly drips on the surface of the water guide cover 13 below due to gravity, and since the water guide cover 13 is conical, the water flow finally passes through the guide flow of the water guide cover 13 to the outer heat dissipation hole 17 for discharge.
