Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0043] Embodiment 1:

[0044] As Figure 1 , Figure 2 shown, the millimeter-wave human body imaging security inspection device includes a detection component 1, a top connection component 2, and a bottom connection component 3; the detection components 1 are arranged at intervals and symmetrically, both ends of the top connection component 2 are respectively connected to the top of the detection component 1, and both ends of the bottom connection component 3 are respectively connected to the bottom of the detection component 1. The middle part of the millimeter-wave human body imaging security inspection device runs through horizontally, and the position where people pass is the position where the middle part runs through.

[0045] Specifically, as Figure 3 shown, the detection component 1 includes a box body 11, and the box body 11 includes a rectangular enclosure 111, a wave-transmitting plate 112, and a maintenance door body 113; the rectangular enclosure 111 includes side plates on both sides, a bottom plate at the bottom, and a top plate at the top. The side plates, the top plate and the bottom plate enclose a rectangular frame; one end of the rectangular enclosure 111 is connected to the wave-transmitting plate 112 to form a closed shape, and the wave-transmitting plate 112 is used for the detection wave to pass through to realize detection. The top and bottom inside the rectangular enclosure 111 are connected to the support track 114, and the side surface of the maintenance door body 113 includes a plurality of roller mechanisms 115, and the roller mechanisms 115 are connected to the support track 114.

[0046] The maintenance door body 113 is provided with a ventilation and heat dissipation opening, and the position of the heat dissipation opening is close to the power supply 15 to dissipate heat when the power supply 15 is working.

[0047] Specifically, as Figure 4 , Figure 5 shown, the roller mechanism 115 includes a roller mounting plate 1151, a card slot 1152, and a plurality of rollers 1153; the maintenance door body 113 is vertically arranged, while the roller mounting plate 1151 is horizontally arranged. One end of the roller mounting plate 1151 is connected to the bottom and / or top of the inner side of the maintenance door body 113. Specifically, the roller mounting plate 1151 is fixed by hexagon socket countersunk head screws. Of course, in order to ensure the stability of the device during operation and considering the possible impact on the device stability during repeated operation, at the connection between the roller mounting plate 1151 and the maintenance door body 113, angle pieces or reinforcing ribs are installed to further improve the connection stability and durability through additional support structures. The card slot 1152 is connected to the bottom of the roller mounting plate 1151, and a chute is formed between the card slot 1152 and the roller mounting plate 1151. A sliding connection is formed between the support rail 114 and the chute, and both ends of the roller 1153 are connected to the side card slot 1152, and the plurality of rollers 1153 are arranged at intervals.

[0049] As Figure 4 shown, the support rail 114 is a profile structural member, and its top end has a slide rail along the length direction. The roller mechanism 115 can move along the length direction of the slide rail. The top of the slide rail of the support rail 114 just fits into the chute between the card slot 1152 and the roller mounting plate 1151 to achieve positioning, so that the roller mechanism 115 can only move in the length direction.

[0050] In this embodiment, by installing the roller mechanism 115 on the maintenance door body 113, the disassembly and assembly work between the maintenance door body 113 and the rectangular enclosure 111 is simplified by using the rollers. By pulling open the maintenance door body 113, a larger view can also be obtained, which is convenient for power supply replacement and debugging work of the control system.

[0051] As Figure 6As shown in the figure, the support rail 114 can be in an "E" shape, and multiple roller mechanisms 115 can also be adaptively arranged to achieve sliding connection with multiple slide rails of the support rail 114. The support rail 114 is provided on both the bottom plate and the top plate within the rectangular enclosure 111, and the support rail 114 can be connected to the top plate or the bottom plate by welding or bolt connection. A linear guide module 12 is connected between the support rail 114 on the top plate and the support rail 114 on the bottom plate. The bottom support rails 114 on the left and right sides are also connected by the top cross beam 21 of the top connection assembly 2 and the bottom cross beam 31 of the bottom connection assembly 3. As Figure 6 shown in the figure, the support rail 114 of the detection assembly 1 and the linear guide module 12 form a frame support structure, which can support the entire detection assembly 1. At the same time, the top cross beam 21 and the bottom cross beam 31 can also support the entire millimeter-wave human body imaging security inspection device, ensuring the stability of the entire millimeter-wave human body imaging security inspection device.

[0053] Among them, the linear guide module 12 is located at the middle symmetric position within the box body 11 and is close to the wave-transparent plate 112. The linear guide module 12 can drive the millimeter-wave radar 13 to move up and down. The industrial control computer 14 controls the linear guide module 12 and the millimeter-wave radar 13, etc., and the power supply 15 supplies power to the linear guide module 12, the millimeter-wave radar 13, and the industrial control computer 14.

At the same time, some wire grooves or wire troughs are opened on the power supply box and the industrial control computer installation box to facilitate wiring and avoid messy wires.

[0055] When the device is performing security inspections, the power supply 15 provides the necessary power supply for the entire device, the industrial computer 14 controls the millimeter-wave radar 13 to perform precise linear movement on the linear guide module 12 for detection, and the user prompt screen 5 reminds the detection personnel to follow strict behavioral norms through the intelligent prompt function to ensure the compliance and accuracy of the detection process; when the millimeter-wave radar 13 detects an abnormal situation, it will trigger the warning mechanism, and the alarm light will immediately issue a warning, effectively reminding the staff to intervene for detailed inspections and enhance the safety and efficiency of the entire detection process.

[0056] The power supply system and main control system of the entire device are installed inside the maintenance doors 113 on both sides, which is beneficial to improving the safety and stability of the device, and is convenient for maintenance, saves space, and improves aesthetics; when performing maintenance and equipment overhaul, the maintenance door 113 can be opened as needed to carry out daily maintenance and troubleshooting of the device. The ventilation holes of the maintenance door 113 are used for the heat dissipation needs of the device during continuous operation, effectively preventing the performance degradation of the detection device due to overheating, thereby ensuring the stability and reliability of the device.

[0058] like Figure 2 As shown, the bottom connection component 3 includes a bottom crossbeam 31 and a bottom support plate, wherein the bottom support plate includes a platform plate 32 and a bottom trapezoidal plate 33, the platform plate 32 is located between the two detection components 1, and the bottom trapezoidal plate 33 is trapezoidal. Both ends of the bottom crossbeam 31 are connected to the bottom of the detection component 1, the platform plate 32 can be connected to the bottom crossbeam 31, and the bottom trapezoidal plate 33 is connected to the platform plate 32 and the bottom side of the rectangular enclosure 111.

[0059] Channels for the passage of lines are provided in the top crossbeam 21 of the top connection assembly 2 and the bottom crossbeam 31 of the bottom connection assembly 3 to facilitate the routing of lines. The line channels are specially designed as the wiring paths for the wires, which effectively prevent the entanglement problem caused by too many lines. By arranging the wires of the device in categories and blocks, the line distribution and line fault detection and maintenance work are effectively simplified.

[0060] like Figure 2 As shown, the millimeter wave human body imaging security inspection device also includes a plurality of universal wheels 4, the universal wheels 4 are connected to the detection component 1 and / or the bottom of the bottom connection component 3, and the plurality of universal wheels 4 are evenly distributed. An air outlet can be provided at the connection position of the universal wheel 4. The universal wheel 4 has omnidirectional movement capability, which is convenient for movement.

[0061] In this embodiment, the entire device can be installed in modules, that is, the installation of the bottom connection component 3 and the two-side detection components 1, and the installation of the top connection component 2 and the two-side detection components 1. Through modular design and installation, it has the advantages of simple operation, easy portability, and reduced maintenance costs, facilitating the transportation, disassembly, assembly, upgrade, and daily maintenance of the entire device, effectively avoiding the problem of difficult disassembly and repair of current millimeter-wave security inspection devices. The universal wheels 4 at the bottom are used for movement, with a wide range of applicable scenarios, strong adaptability, and convenient use.

[0062] Currently, most millimeter-wave human body imaging security inspection devices on the market are fixedly connected between the two sides and the top cover and the base. When replacing the power supply 15 and checking the control system, it is relatively difficult. In this embodiment, the maintenance door body 113 in the detection component 1 is connected to the support track 114 through the roller mechanism 115, which greatly facilitates the replacement of the power supply 15 of the security inspection device and related maintenance work.
