Description

Technical Field

[0001] This invention relates to the field of scanning inspection technology, and in particular to an inspection device and a transition method based on the inspection device. Background Technology

[0002] Currently, important departments such as customs, civil aviation airports, and railway systems typically need to scan and inspect all vehicles and goods passing through customs for purposes such as combating smuggling and counter-terrorism. Scanning and inspection systems utilize the principle of radiographic imaging to obtain perspective images of objects inside containers / vehicles without opening them. Analysis of these images can then identify suspicious items hidden within the containers or vehicles.

[0003] Existing scanning inspection systems typically require disassembling their components (such as the boom, cabin, detectors, and radiation sources) before transporting them. This necessitates reinstallation and recalibration at the inspection site, along with the reconstruction of protective barriers and related civil engineering work. This process is time-consuming and requires significant manpower.

[0004] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an inspection device and a transfer method based on the inspection device, so as to solve the problem that existing inspection systems need to be reinstalled and debugged at the inspection site.

[0006] To achieve the above objectives, the present invention provides an inspection device, comprising:

[0007] The boom is equipped with multiple detectors and is used to form an inspection channel;

[0008] The first compartment is equipped with a radiation source and is connected to a boom; and

[0009] The protective wall, connected to the first chamber or boom, is used to provide radiation protection to the object to be protected.

[0010] The boom, first hull, and protective wall are designed to be transported together in a connected state.

[0011] Optionally, the relative position between the boom and the first cabin is configured to remain unchanged in the transport and working states of the inspection device in the direction of the inspection channel extension.

[0012] Optionally, the protective wall can be folded toward the centerline of the inspection channel to shorten its length in the direction of the inspection channel during transport.

[0013] Optionally, the protective wall includes:

[0014] First protective section;

[0015] Second protective section; and

[0016] Connectors;

[0017] The first protective section and the second protective section are movably connected by a connector, and the second protective section can be folded relative to the first protective section toward the centerline of the inspection channel.

[0018] Optionally, in the direction of the extension of the inspection passage, the first protective section is disposed between the front and rear sides of the first compartment, and the second protective section is disposed at least partially outside the front or rear side of the first compartment, and when folded, the second protective section is located between the front and rear sides of the first compartment.

[0019] Optionally, the height of the protective wall is set to be less than or equal to the height of the first hull.

[0020] Optionally, in the direction of the inspection channel's extension, the height of the protective wall's cross-section gradually decreases away from the boom.

[0021] Optionally, the boom is retractable relative to the first compartment.

[0022] Optionally, the boom is configured to be in an elevated state when the inspection device is in operation; and in a lowered state when the inspection device is in transport, and after lowering, it does not exceed the height of the first cabin or the maximum height limit for road travel.

[0023] Optionally, the inspection device also includes a second cabin, and the boom has a portal frame structure including a horizontal arm and two vertical arms respectively connected to both sides of the horizontal arm, with the first cabin and the second cabin respectively connected to the two vertical arms.

[0025] Optionally, the width of the boom in the direction perpendicular to the extension direction of the inspection channel is adjustable.

[0026] To achieve the above objectives, the present invention also provides a transfer method based on the above-described inspection device, comprising:

[0027] With the boom connected to the first compartment and the protective wall connected to the first compartment or the boom, the boom, the first compartment, and the protective wall are transported together to achieve relocation.

[0028] Optionally, the following may also be included before shipping:

[0032] Based on the above technical solution, this invention effectively solves the problem of the inspection system in the prior art needing to be reinstalled and debugged on the inspection site by setting the boom, the first cabin and the protective wall to be transported together in a connected state. This helps to reduce installation time and manpower input. Moreover, the protective wall is also transported together with the boom and the first cabin in a connected state, which can avoid rebuilding the protective wall and carrying out the civil engineering work on the inspection site. This allows the inspection device to be put into operation quickly after being transported to the inspection site, greatly shortening the time spent from transportation to operation and improving the efficiency of site transfer.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0042] refer to Figure 1 and Figure 2 As shown in an illustrative embodiment of the inspection device provided by the present invention, the inspection device includes a boom 1, a first chamber 2 and a protective wall 3. The boom 1 is equipped with multiple detectors, the first chamber 2 is equipped with a radiation source, and the boom 1 is used to form an inspection channel 5. When the object to be inspected passes through the inspection channel 5, the radiation emitted by the radiation source passes through the object to be inspected and is received by the detector. By analyzing the information received by the detector, it can be determined whether the object to be inspected meets the safety standards.

[0043] The first cabin 2 is connected to the boom 1, and the protective wall 3, which is used to provide radiation protection to the object to be protected, is connected to the first cabin 2 or the boom 1. The boom 1, the first cabin 2 and the protective wall 3 are configured to be transported together in the connected state.

[0044] In the above illustrative embodiment, by transporting the boom 1, the first cabin 2, and the protective wall 3 together in a connected state, the problem of the inspection system in the prior art needing to be reinstalled and debugged on the inspection site can be effectively solved, which helps to reduce installation time and manpower input. Moreover, the protective wall is also transported together with the boom and the first cabin in a connected state, which can avoid rebuilding the protective wall and carrying out the civil engineering work on the inspection site, so that the inspection device can be put into operation quickly after being transported to the inspection site, greatly shortening the time spent from transportation to operation of the inspection device and improving the efficiency of site transfer.

[0045] Furthermore, in the extension direction of the inspection channel 5, the relative position between the boom 1 and the first cabin 2 is configured to remain unchanged in both the transport and operational states of the inspection device. The advantage of this configuration is that the relative position of the detector on the boom 1 and the radiation source on the first cabin 2 remains constant in both transport and operational states, saving time required for readjusting the relative positions of the detector and radiation source at the inspection site. This allows the inspection device to be put into inspection work more quickly after being unloaded from the transport equipment.

[0046] like Figure 1As shown, boom 1 has a portal frame structure, comprising two vertical arms and a horizontal arm connected to the tops of the two vertical arms. Inspection channel 5 is formed between the two vertical arms. Figure 2 As shown, the "extension direction of inspection channel 5" is a direction that is perpendicular to both the length direction of the vertical arm and the length direction of the horizontal arm. The "centerline of inspection channel 5" is a centerline that is parallel to the extension direction of inspection channel 5 and located in the middle of inspection channel 5. This centerline is located between the two vertical arms.

[0047] Optionally, the protective wall 3 can be folded towards the centerline of the inspection channel 5 to shorten its length in the direction of extension of the inspection channel 5 during transportation. This arrangement reduces the space occupied by the protective wall 3 and facilitates transportation.

[0048] When the inspection device is in operation, the protective walls 3 are located on both sides of the inspection channel 5 to prevent radiation leakage. When the inspection device is in transport mode, the protective walls 3 are located inside and / or attached to the first compartment 2. In transport mode, the protective walls 3 and the first compartment 2 are folded together to form a cuboid structure. This configuration in transport mode makes the inspection device more suitable for overall relocation, transportation, and storage.

[0049] Specifically, the protective wall 3 includes a first protective section, a second protective section, and a connector. The first and second protective sections are movably connected by the connector, and the second protective section can be folded relative to the first protective section toward the centerline of the inspection channel 5.

[0050] In some embodiments, the inspection device further includes a locking structure for holding two protective walls 3 located on one side of the first compartment 2 together, or for holding each protective wall 3 together with the first compartment 2 or the second compartment 4 mentioned later. The locking structure may be a snap-fit ​​structure, a pin structure, a rope, a chain, etc.

[0051] Furthermore, such as Figure 2 and Figure 4 As shown, in the extension direction of the inspection channel 5, the first protective section is located between the front and rear sides of the first compartment 2, and the second protective section is at least partially located outside the front or rear side of the first compartment 2, and after folding, the second protective section is located between the front and rear sides of the first compartment 2. The advantage of this arrangement is that the protective wall 3 can be completely folded into the space between the front and rear sides of the first compartment 2 after folding, so that the width of the entire inspection device in the front-rear direction is approximately equal to the width of the first compartment 2, minimizing the width of the entire inspection device and facilitating transportation.

[0052] The present invention does not limit the folding method of the protective wall 3. For example, the second protective section can be folded relative to the first protective section by translation, rotation or repeated disassembly and assembly.

[0053] Optionally, twice the length of the second protective section is equal to or greater than the lateral distance between the two vertical arms of boom 1.

[0054] When the length of the second protective section is twice the lateral distance between the two vertical arms of boom 1, the second protective sections on the left and right sides fold inward and align perfectly, closing the inspection passage 5 like two doors. When the length of the second protective section is greater than twice the lateral distance between the two vertical arms of boom 1, the second protective sections on the left and right sides fold inward and overlap each other. This can reduce the front and rear width of the inspection device through folding and also provide a larger radiation protection range.

[0055] Optionally, in the extension direction of the inspection channel 5, the height of the cross-section of the protective wall 3 gradually decreases towards the direction away from the boom 1. This arrangement can minimize the volume of the protective wall 3 and reduce the overall weight of the inspection device while achieving comprehensive protection as much as possible.

[0056] In the above embodiments, the protective wall 3 can be a heavy metal shielding plate, such as a lead plate.

[0057] Optionally, the boom 1 is height-adjustable relative to the first compartment 2. This configuration allows the boom 1 to have a higher inspection channel 5 height when in operation, enabling the inspection of taller vehicles or containers and providing a wider inspection range. During transport, the boom 1 can be lowered to reduce the overall height of the inspection device, meeting transport requirements and improving transport safety.

[0058] The boom 1 has a portal frame structure, including a horizontal boom and two vertical booms connected to both sides of the horizontal boom. The two vertical booms are set up in a multi-level box-type nested structure to achieve lifting and lowering; or a guide rail structure can be used to achieve lifting and lowering.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, boom 1 is configured to be in the raised state when the inspection device is in operation; and in the lowered state when the inspection device is in transport mode, and the lowered boom does not exceed the height of the first cabin 2. The advantage of this configuration is that during transport, the height of boom 1 does not exceed the height of the first cabin 2, minimizing the overall height of the inspection device and facilitating transport. Alternatively, it ensures that the lowered boom 1 does not exceed the maximum height limit for road travel, guaranteeing road safety.

[0060] Optionally, the height of the protective wall 3 is set to be less than or equal to the height of the first compartment 2. This setting ensures that the height of the entire inspection device is approximately equal to the height of the first compartment 2 during transportation, minimizing the overall height of the inspection device and avoiding exceeding the height restrictions for vehicles during road transport.

[0061] Optionally, the inspection device also includes a second chamber 4, which can have the same specifications as the first chamber 2 to ensure a more aesthetically pleasing appearance of the entire inspection device. Alternatively, the second chamber 4 can be of a different specification than the first chamber 2; optionally, the size of the second chamber 4 can be smaller than the size of the first chamber 2 to reduce the weight of the entire inspection device.

[0062] The first compartment 2 and the second compartment 4 can adopt a closed structure with an outer cover, which is beneficial to protect the internal structure and prevent sand and dust from entering the components inside the compartment, and the appearance is also more aesthetically pleasing; the first compartment 2 and the second compartment 4 can also adopt a frame structure to reduce the overall weight.

[0063] The boom 1 has a portal frame structure, comprising a horizontal boom and two vertical booms connected to both sides of the horizontal boom. The first cabin 2 and the second cabin 4 are connected to the two vertical booms respectively. This arrangement allows for better symmetry of the entire structure and a more rational structural layout.

[0064] Optionally, the first chamber 2 is configured to be fixed relative to the ground when the inspection device is in operation, and further, the entire inspection device is fixed relative to the ground. In operation, the inspection device remains stationary, while the object being inspected moves relative to the inspection device to complete the scanning inspection. This configuration simplifies the structure of the inspection device, eliminating the need for a walking mechanism on the first chamber 2, which also makes transportation and installation of the inspection device more convenient and effective.

[0065] Optionally, the width of the boom 1 in the direction perpendicular to the extension direction of the inspection channel 5 is adjustable. That is, the boom 1 can be retracted laterally inward, configuring the boom 1 such that its width is greater when the inspection device is in operation than when the inspection device is in transport mode. When the inspection device is in operation, the larger width of the boom 1 improves its stability; when the inspection device is in transport mode, the reduced width of the boom 1 reduces the overall volume of the inspection device, minimizes space occupation, and facilitates transportation.

[0066] In some embodiments, the boom 1 includes a first vertical arm, a second vertical arm, and a horizontal arm. The first vertical arm is telescopically or vertically mounted on the first housing 2. The second vertical arm is telescopically or vertically mounted on the second housing 4. The two ends of the horizontal arm are respectively connected to the upper ends of the first and second vertical arms. This arrangement facilitates rapid and accurate changes in the position of the boom 1 when the inspection device switches between working and transport states, and reduces the debugging work of the inspection device after relocation.

[0067] In some embodiments, the detector includes a first detection part disposed on a cross arm and a second detection part whose position is variable relative to the cross arm. In the operating state, the second detection part is located on one side of the inspection channel, and in the transport state, the second detection part is disposed on the cross arm. This arrangement allows the detector to adapt to both the operating and transport states, and prevents the detector from interfering with the switching of the inspection device between the operating and transport states without affecting the detector's function.

[0068] For example, in the working state, the second detection unit can be vertically located on one side of the inspection channel, or it can be at a certain angle to the vertical direction; in the transportation state, the second detection unit can be arranged on the horizontal arm, for example, side by side with the first detection unit in the horizontal direction or side by side with the first detection unit in the vertical direction along the extension direction of the horizontal arm.

[0069] In some embodiments, the second detection unit may be hinged to the first detection unit, and the second detection unit changes its relative position with the horizontal arm by rotating about the first detection unit. In other embodiments, the second detection unit may be hinged to the boom 1, and the second detection unit changes its relative position with the horizontal arm by rotating about the boom 1. For example, the second detection unit may be hinged to the horizontal arm or the vertical arm. The second detection unit being hinged to the first detection unit or the boom 1 facilitates the rapid and accurate positioning of the detector when the inspection device quickly switches between working and transport states, thereby shortening the switching time of the inspection device, and also facilitates the detector being in an accurate detection position when in working state.

[0070] The connection between the second detection unit and the first detection unit or the boom 1 is not limited to a hinge. For example, in the working state and the transportation state, the second detection unit can also be detachably connected to the corresponding position.

[0071] This invention does not limit the arrangement of equipment within the first chamber 2 or the second chamber 4. For example, the second chamber 4 of this invention can be equipped with detectors, electrical equipment required for the inspection device, and a control console. The first chamber 2 and the second chamber 4 can also each be equipped with a radiation source, or each can each be equipped with a detector, etc.

[0072] Based on the inspection device described above, the present invention also proposes a transition method based on the inspection device.

[0073] Optionally, the transfer method based on the above-mentioned inspection device includes:

[0074] With boom 1 connected to first cabin 2 and protective wall 3 connected to first cabin 2 or boom 1, boom 1, first cabin 2 and protective wall 3 are transported together to achieve relocation.

[0075] Optionally, the following may also be included before shipping:

[0076] Fold the protective wall 3 towards the center line of the inspection channel 5.

[0077] Optionally, the following may also be included before shipping:

[0078] Lower boom 1 to a height not exceeding that of the first cabin 2 or the maximum height limit for road travel.

[0079] The positive technical effects of the inspection device in the above embodiments are also applicable to the transfer method based on the inspection device, and will not be repeated here.

[0080] The following is in conjunction with the appendix Figures 1-4 The specific structure and transition process of an embodiment of the inspection device of the present invention and the transition method based on the inspection device will be described as follows:

[0081] like Figure 1 As shown, the inspection device includes a boom 1, a first compartment 2, a protective wall 3, and a second compartment 4. The boom 1 includes a horizontal arm and two vertical arms, forming an inspection channel 5 between the two vertical arms. The first compartment 2 and the second compartment 4 are connected to the two vertical arms on both sides of the boom 1, and the boom 1 is positioned between the front and rear sides of the first compartment 2 and the second compartment 4 in the direction of extension of the inspection channel 5. The two protective walls 3 are connected to the first compartment 2 and the second compartment 4 respectively, and the height of the protective walls 3 is approximately equal to the height of the first compartment 2 and the second compartment 4. In this figure, the inspection device is in the working state, and the boom 1 is in the raised state.

[0082] like Figure 2 As shown, the protective walls 3 consist of four sets, respectively located on the front and rear sides of the first chamber 2 and the front and rear sides of the second chamber 4. A certain distance is maintained between the two sets of protective walls 3 located on the front and rear sides of the first chamber 2 to ensure that the radiation emitted by the radiation source can smoothly irradiate the object being inspected. A certain distance can also be maintained between the two sets of protective walls 3 located on the front and rear sides of the second chamber 4, so that this distance is protected by the second chamber 4; alternatively, they can be connected to form a continuous protective wall for better protection. In this figure, the inspection device is in operation, and the protective walls 3 are in an open state.

[0083] like Figure 3 As shown, the inspection device is in transport mode. The boom 1 is lowered to a height below the first compartment 2 and the second compartment 4, so that the height of the entire inspection device is approximately equal to the height of the first compartment 2 and the second compartment 4. At the same time, the protective wall 3 is folded inward toward the centerline of the inspection channel 5.

[0084] like Figure 4 As shown, the inspection device is in transport mode, the protective wall 3 is folded inward, and after folding, the protective wall 3 is located between the front and rear sides of the first compartment 2 and the second compartment 4, so that the width of the entire inspection device in the front and rear direction is approximately equal to the width of the first compartment 2 and the second compartment 4.

[0085] Before transportation, the boom 1 is lowered below the height of the first cabin 2 and the second cabin 4 so that the height of the entire inspection device is approximately equal to the height of the first cabin 2 and the second cabin 4; at the same time, the four sets of protective walls 3 are folded inward toward the centerline of the inspection channel 5, and after folding, the four sets of protective walls 3 are located between the front and rear sides of the first cabin 2 and the second cabin 4 so that the width of the entire inspection device is approximately equal to the width of the first cabin 2 and the second cabin 4.

[0086] After boom 1 is lowered and protective wall 3 is folded, the inspection equipment is transported to another location while boom 1, first cabin 2, protective wall 3 and second cabin 4 are all connected.

[0087] Upon arrival at the inspection site, the inspection device is unloaded from the transport equipment. The boom 1, the first cabin 2, the protective wall 3, and the second cabin 4 remain connected. No reinstallation or re-adjustment is required on site, nor is it necessary to temporarily build a protective wall or carry out civil engineering work on the protective wall. Simply raise the boom 1 and unfold the protective wall 3 to put the inspection device into operation.

[0088] Through the description of several embodiments of the inspection device and the transition method based on the inspection device of the present invention, it can be seen that the embodiments of the inspection device and the transition method based on the inspection device of the present invention have at least one or more of the following advantages:

[0089] 1. By transporting the boom, first cabin, and protective wall together in a connected state, the problem of needing to reinstall and debug the inspection system at the inspection site in the existing technology can be effectively solved, reducing installation time and manpower input;

[0090] 2. The protective wall is transported together with the boom and the first cabin in the connected state, which can avoid rebuilding the protective wall and carrying out the civil engineering work on the inspection site, so that the inspection equipment can be put into operation as soon as possible and improve the efficiency of site transfer.

[0091] 3. The protective wall is foldable, which helps to reduce the width of the entire inspection device;

[0092] 4. The boom is height-adjustable, which helps to reduce the overall height of the inspection device and facilitates the free switching between the inspection device in transportation and working states.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
