DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "include", "comprises", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Combine the following Figures 1 to 11 The inspection device according to the embodiment of the present utility model is described.

[0040] like Figure 1 and Figure 2As shown, the inspection device provided by the embodiment of the utility model includes a scanning channel, a scanning device and a cover body 1; the scanning device is configured to radiate rays toward the object to be inspected in the scanning channel during inspection to form a scanning image; the cover body 1 is obtained by splicing N cover plates, and a accommodating space is formed inside the cover body 1, and the accommodating space accommodates the scanning device, and N is an integer greater than or equal to 2; for any two spliced ​​cover plates, the splicing edges of the two cooperate with each other to form a water guide groove 2, and the water guide groove 2 is used to receive water from the outside of the cover body 1 and guide the water to a position outside the scanning device and the scanning channel.

[0041] Specifically, a scanning channel is constructed inside the inspection device, and a scanning device is arranged around the circumference of the scanning channel. The scanning device is installed in the internal space of the support frame, and the support frame is used to install the cover body 1, and a storage space for accommodating the scanning device is formed inside the cover body 1. The object to be inspected enters the scanning channel, and the scanning device radiates rays toward the object to be inspected in the scanning channel, obtains a scanned image of the object to be inspected, and identifies or diagnoses the object to be inspected based on the scanned image.

[0042] The cover body 1 is arranged outside the scanning device to protect the scanning device and the auxiliary parts of the inspection equipment. Since the scanning device has a large size, the cover body 1 is usually composed of multiple cover plates. In order to facilitate the assembly and disassembly of the cover body 1 and the regular maintenance of the scanning device inside the cover body 1, the cover plates are usually connected by fasteners, which include screws and nuts.

[0043] There will be a joint gap where two adjacent cover plates are joined. If there is no waterproof structure at the joint gap, when the inspection equipment is used outdoors, rainwater will enter the inspection equipment through the joint gap in rainy and snowy weather, causing damage to the core components of the equipment. Or if there is a fire at the site and fire extinguishing is required, the sprayed liquid will enter the inspection equipment through the joint gap; or if there is a sudden situation such as water leakage at the site, the external liquid will enter the inspection equipment through the joint gap. In the case of the above situation, the inspection equipment will cause damage to its core components, and the subsequent maintenance cost will be high.

[0044] For the two spliced ​​cover plates, the end splicing area of ​​the cover plates is structurally designed so that the splicing edges of the two cover plates cooperate with each other to form a water guide groove 2. The water guide groove 2 can receive water from the outside of the cover body 1. The water can flow along the extension direction of the water guide groove 2 and finally flow from the end of the water guide groove 2 to a position outside the scanning device and the scanning channel.

[0045] According to this embodiment, the waterproof design is implemented by the joint edges of the cover plate itself cooperating with each other, which saves more materials and processes than adding an additional waterproof structure, and can make the core area of ​​the device have a higher waterproof and dustproof level.

[0046] like Figure 3 As shown, the two joined cover plates at the top of the cover body 1 are taken as an example for explanation, and the two joined cover plates are defined as a first top cover plate 113 and a second top cover plate 114. The first top cover plate 113 includes a first plate body, a U-shaped bending portion formed by bending the end of the first plate body, and a connecting portion formed by bending the end of the U-shaped bending portion, and the U-shaped bending portion includes a first side wall, a first bottom wall, and a second side wall connected in sequence. The second top cover plate 114 includes a second plate body, an L-shaped bending portion formed by bending the end of the second plate body, and the L-shaped bending portion includes a third side wall and a second bottom wall connected.

[0047] When the first top cover plate 113 and the second top cover plate 114 are spliced, the first plate body and the second plate body are in the same plane, the first side wall and the third side wall are parallel to each other, and there is a first gap between the first side wall and the third side wall; the first bottom wall and the second bottom wall are parallel to each other, and there is a second gap between the first bottom wall and the second bottom wall, and the width of the second bottom wall is smaller than the width of the first bottom wall; the second bottom wall is not higher than the top of the second side wall, and there is a gap between the free end of the second bottom wall and the second side wall. Thus, the first side wall, the first bottom wall, the second side wall, the second bottom wall and the third side wall enclose a water channel 2.

[0048] Specifically, the cover body 1 has a top, two opposite side parts and two opposite ends. The cover body 1 is formed by splicing a plurality of cover plates. A sealing area is constructed at the joint of the two cover plates. A sealing strip is installed in the sealing area to effectively prevent dust and prevent external debris from entering the interior of the device. The sealing strip also has a waterproof effect. The water guide groove 2 is located at the periphery of the sealing area. The water guide groove 2 can drain the accumulated water in the water guide groove 2 to the outside of the device.

[0049] like Figure 3 As shown, taking the top of the cover body 1 as an example, the two cover plates spliced ​​together at the top of the cover body 1 are respectively a first top cover plate 113 and a second top cover plate 114, the first top cover plate 113 includes a first plate body and a first side wall, a first bottom wall, a second side wall and a connecting portion formed by bending the end of the first plate body in sequence, and the second cover plate includes a second plate body and a second side wall and a second bottom wall formed by bending the end of the second plate body in sequence.

[0050] The first bottom wall, the second bottom wall and the second side wall are enclosed, and a sealing strip is installed in the sealing area. The sealing strip has a top surface and a bottom surface opposite to each other, and a first side surface and a second side surface opposite to each other, so as to form a sealed water guide groove. The bottom surface of the sealing strip is in contact with the first bottom wall, the top surface of the sealing strip is in contact with the second bottom wall, and the first side surface of the sealing strip is in contact with the second side wall, so that the sealing strip plays an effective dustproof role. The first side wall, the first bottom wall, the second side surface of the sealing strip, the second bottom wall and the third side wall are enclosed to form a water guide groove 2.

[0051] Water outside the housing 1 can flow into the water channel 2 along the first gap between the first side wall and the third side wall, and further flow from the end of the water channel 2 to a position outside the housing 1. The top of the second side wall is higher than the second bottom wall, and the second side wall plays an effective blocking role, which can prevent the accumulated water in the water channel 2 from flowing into the interior of the device from the top of the second side wall.

[0052] The connecting part is a plate-shaped body, and the connecting part is parallel to the second plate body. A first mounting hole is opened on the connecting part, and a second mounting hole is opened on the second plate body. The fastener passes through the first mounting hole and the second mounting hole to realize the connection between the first top cover plate 113 and the second top cover plate 114, and the first top cover plate 113 and the second top cover plate 114 are detachably connected to facilitate installation and disassembly.

[0053] Two adjacent cover panels are spliced ​​together, and the splicing edges of the cover panels themselves cooperate with each other to form a water guide groove 2. There is no need to add an additional waterproof structure. Water from the outside of the cover body 1 can be drained along the water guide groove 2 to the outside of the scanning device and the scanning channel, which is beneficial to reducing production costs.

[0054] In an embodiment of the utility model, the scanning device is accommodated in the accommodating space of the cover body 1. The cover body 1 is formed by splicing a plurality of cover panels. The splicing edges of the two spliced ​​cover panels cooperate with each other to form a water guide groove 2. Water from the outside of the cover body 1 flows into the water guide groove 2, and further flows along the extension direction of the water guide groove 2 to the end of the water guide groove 2, and is discharged from the end of the water guide groove 2 to the outside of the cover body 1. The water will not flow inward, thereby effectively protecting the interior of the inspection equipment.

[0055] In an optional embodiment, based on the shapes of N cover plates, the cover body 1 is divided into M sealing areas, the water guide groove 2 is located at the periphery of each sealing area, and M is an integer greater than or equal to 1.

[0056] like Figure 4 The local sealing area shown is described by taking the position where the top of the cover body 1 and the side of the cover body 1 are spliced ​​as an example, and the two cover plates spliced ​​at the top of the cover body 1 and the side of the cover body 1 are defined as the end cover plate 115 and the side cover plate 116. The end cover plate 115 includes a third plate body, a fourth side wall formed by bending the end of the third plate body, and a third bottom wall formed by bending the end of the fourth side wall. The side cover plate 116 includes a fourth plate body, a fourth bottom wall formed by bending the end of the fourth plate body, and a fifth side wall connected to the fourth bottom wall, and the top surface of the fifth side wall is higher than the fourth bottom wall. The fourth side wall and the fourth plate body are located in the same plane, the third bottom wall and the fourth bottom wall are arranged in parallel and spaced apart, and a sealing strip is sandwiched between the third bottom wall and the fourth bottom wall. The three surfaces of the sealing strip connected in sequence are respectively in contact with the third bottom wall, the fifth side wall and the fourth bottom wall, and the sealing strip plays an effective dustproof role.

[0057] like Figure 5BThe overall schematic diagram of the sealing area A and the sealing area B is shown. After removing part of the cover plate, the approximate positions of the sealing area A and the sealing area B are marked with dotted lines. The sealing strip can be located between the cover plate and the frame, and the water guide groove can be located outside the sealing area. The sealing area A is a rectangular area, which can be located at the connection between the rectangular cover plate and the frame to achieve a waterproof and dustproof effect. The sealing area B is an area at the corner, which can cooperate with the cover plate that forms the angle to achieve a waterproof and dustproof effect. The sealing area A and the sealing area B are provided with a water guide groove on the periphery.

[0058] Therefore, the cover body 1 is divided into a plurality of sealing areas according to the shape and installation characteristics of the cover plates in different areas of the cover body 1, and the sealing areas are designed specifically to effectively improve the waterproof effect while preventing dust.

[0059] In an embodiment of the utility model, the splicing edges of the two spliced ​​cover plates are constructed with a water guide groove and a sealing strip is installed, which plays an effective dustproof role. The water guide groove 2 is located at the periphery of the sealing area, and the accumulated water is drained to the outside of the equipment through the water guide groove 2, effectively improving the waterproof and dustproof function of the inspection equipment.

[0060] like Figure 1 , Figure 2 , Figure 5A and Figure 6 As shown, in an optional embodiment, the cover body 1 includes K sub-cover bodies 1 connected in sequence, K is an integer greater than or equal to 2, the cover body 1 includes a first sub-cover body 11 and a second sub-cover body 12, the first sub-cover body 11 includes a first end face, and the first sub-cover body 11 defines a part of the accommodation space; the second sub-cover body 12 includes a second end face, and the second sub-cover body 12 defines a part of the accommodation space; the first end face and the second end face are sealed and connected by a first sealing strip 15, and the first sealing strip 15 is configured to form a sealing area between the first sub-cover body 11 and the second sub-cover body 12. It can be understood that there can be one or more first sealing strips 15, and the sealing area between the first sub-cover body 11 and the second sub-cover body 12 can have one or more separated sub-areas.

[0061] Specifically, the scanning device is usually composed of a plurality of scanning components arranged in sequence, each scanning component has a different function, and each scanning component has a different height. The corresponding cover body 1 is composed of a plurality of sub-cover bodies 1 connected in sequence, and the height of each sub-cover body 1 is adapted to the height of the scanning component.

[0062] The two adjacent sub-enclosures 1 of the enclosure 1 are defined as the first sub-enclosure 11 and the second sub-enclosure 12. The first sub-enclosure 11 has a first end surface facing the second sub-enclosure 12, and the second sub-enclosure 12 has a second end surface facing the first sub-enclosure 11. Both the first sub-enclosure 11 and the second sub-enclosure 12 have a receiving space.

[0063] At the first end face of the first sub-cover body 11, a sealing strip is arranged along the circumferential direction of the edge of the first end face, and this sealing strip is defined as the first sealing strip 15. The first sealing strip 15 can be bonded to the edge of the first end face by bonding to form a sealing area. After the first sub-cover body 11 and the second sub-cover body 12 are paired, the first sealing strip 15 is sandwiched between the first end face and the second end face, and the first sealing strip 15 plays an effective role in dustproof and waterproof. The first sealing strip 15 can effectively prevent debris from entering the interior of the device along the joint gap between the two sub-cover bodies 1. Alternatively, the first sealing strip 15 is bonded to the edge of the second end face. After the first sub-cover body 11 and the second sub-cover body 12 are paired, the first sealing strip 15 is sandwiched between the first end face and the second end face.

[0064] For example, the scanning device includes a CT component, a DR component and two shielding components, and the sub-covers provided on the CT component and the DR component are defined as the first sub-cover 11 and the second sub-cover 12, respectively, and the sub-covers provided on the two shielding components are defined as the third sub-cover 13 and the fourth sub-cover 14. The butt end surfaces of the second sub-cover 12 and the third sub-cover 13 are also sealed and connected by the first sealing strip 15, and the butt end surfaces of the first sub-cover 11 and the fourth sub-cover 14 are also sealed and connected by the first sealing strip 15. Thus, along the length direction of the cover 1, the butt end surfaces of the two adjacent sub-covers are sealed and connected by the first sealing strip 15.

[0065] In the embodiment of the utility model, the end faces of any two adjacent sub-cover bodies are sealed and connected by the first sealing strip 15. The first sealing strip 15 is clamped between the end faces of the two adjacent sub-cover bodies 1 to form a sealing area, which effectively prevents impurities from entering the interior of the device along the joint gap between the two sub-cover bodies, thereby ensuring the overall dustproof and waterproof effect of the cover body 1.

[0066] like Figure 5A and Figure 6 As shown, in an optional embodiment, the first sub-cover body 11 includes S first sub-cover panels 111, the second sub-cover body 12 includes S second sub-cover panels 121, the first end surface includes S first sub-end surfaces located at the S first sub-cover panels 111, and the second end surface includes S second sub-end surfaces located at the S second sub-cover panels 121; the S first sub-end surfaces are sealedly connected to the S second sub-end surfaces in a one-to-one correspondence, and the sealing area between the first sub-cover body 11 and the second sub-cover body 12 is divided into S sub-sealing areas, and S is an integer greater than or equal to 1.

[0067] Specifically, the first sub-cover body 11 has a first end face facing the second sub-cover body 12, and the cover plate corresponding to the first end face is divided into S first sub-cover plates 111, and the S first sub-cover plates 111 correspond to the S first sub-end faces; the second sub-cover body 12 has a second end face facing the first sub-cover body 11, and the cover plate corresponding to the second end face is divided into S second sub-cover plates 121, and the S second sub-cover plates 121 correspond to the S second sub-end faces. The number of first sub-end faces and the number of second sub-end faces are divided according to actual needs, and the first sub-end face and the second sub-end face are sealed and connected at the joint gap by the first sealing strip 15.

[0068] For example, the first end surface of the first sub-cover body 11 is divided into six first sub-end surfaces, and the corresponding second end surface of the second sub-cover body 12 is also divided into six second sub-end surfaces. The upper part of the second end surface is distributed with three second sub-end surfaces, and the lower part of the second end surface is distributed with three second sub-end surfaces, and the scanning channel passes through the second sub-end surface located in the middle of the upper part.

[0069] A first sealing strip 15 is bonded to each second sub-end face, and the first sealing strip 15 is in a closed loop structure. After the first end face of the first sub-cover body 11 and the second end face of the second sub-cover body 12 are paired, the six first sub-end faces correspond to the six second sub-end faces. A first sealing strip 15 is sandwiched between any first sub-end face and the corresponding second sub-end face, so that the six first sealing strips 15 divide the sealing area at the end faces of the first sub-cover body 11 and the second sub-cover body 12 into six sub-sealing areas.

[0070] The six sub-sealing areas are independent of each other and realize their own functions. For example, the sub-sealing area corresponding to the scanning channel ensures the sealing of the scanning channel. For example, an air inlet fan 3 is installed at one of the second sub-end faces, and the air inlet fan 3 is used to draw the cold air in the first sub-cover body 11 into the second sub-cover body 12, and the corresponding sub-sealing area ensures the sealing of the air inlet. For example, an air outlet fan 4 is installed at one of the second sub-end faces, and the air outlet fan 4 is used to send the hot air in the second sub-cover body 12 into the first sub-cover body 11, and the corresponding sub-sealing area ensures the sealing of the air outlet.
