[0053] Pig carcasses usually refer to the carcasses obtained after the head, lower limbs (wrist joints, below the hock joints), viscera (retaining lard and kidneys), and hair of the pigs are removed after slaughter. In related technologies, radiation detection equipment uses a sealed structure with a top and a lead curtain to achieve radiation protection. However, the sealed structure with a top is not suitable for pig carcass processing production lines in the form of hanging rails, and the lead curtain will cause contamination of the pig carcasses when it comes into contact with the pig carcasses.

[0054] In view of this, an embodiment of the present disclosure provides a detection device 1000 for performing radiation detection on a suspension body 100, comprising: a transmission device 1, comprising a suspension mechanism 11 and a moving mechanism 12, the suspension mechanism 11 is used to suspend the suspension body 100 to be detected, and the moving mechanism 12 is used to move the suspension body 100 in a suspended state, so that the suspension body 100 moves along a first direction X through a detection channel; a ray source 2, arranged on a first side of the detection channel, and used to emit rays; a detector 3, arranged on a second side of the detection channel, the first side and the second side are two opposite sides of the detection channel, respectively. On the other hand, the detector 3 is used to receive radiation emitted from the radiation source 2 and passing through the suspension body 100; a radiation protection structure is used to protect radiation from leaking out of the detection channel, and includes a first radiation protection wall 41, a second radiation protection wall 42 and a protection bottom plate 43. The first radiation protection wall 41 and the second radiation protection wall 42 are respectively located on the first side and the second side of the detection channel, and the protection bottom plate 43 is located between the radiation source 2 and the detector 3 in the second direction Y, and is located on the ground of the detection area, wherein the second direction Y intersects with the first direction X and the second direction Y is a direction from the radiation source 2 to the detector 3.

[0055] In some embodiments, the hanging body 100 includes a pig carcass. It is understandable that other livestock carcasses, such as sheep carcasses, cattle carcasses, etc., and other objects with similar shapes and detection requirements are also applicable to the present disclosure.

[0056] Refer to the following Figures 1A to 5 A detection device 1000 for performing radiation detection on a suspension body 100 according to an embodiment of the present disclosure is described.

[0057] Figure 1A is a top view of a detection device 1000 according to some exemplary embodiments of the present disclosure; Figure 1B is a side view of a detection device 1000 according to some exemplary embodiments of the present disclosure; Figure 1C is a partial view of a detection device 1000 according to some exemplary embodiments of the present disclosure.

[0058] like Figure 1A and Figure 1B As shown, in some embodiments, the detection device 1000 includes a transmission device 1, a radiation source 2, a detector 3 and a radiation protection structure 4.

[0059] The transmission device 1 includes a suspension mechanism 11 and a moving mechanism 12. The suspension mechanism 11 is used to suspend the suspension body 100 to be detected, and the moving mechanism 12 is used to move the suspension body 100 in a suspended state, so that the suspension body 100 moves along a first direction X through the detection channel. The first direction X can be understood as the moving direction of the suspension body 100 in the detection channel. Usually, the transmission device 1 is set in the area directly above the detection channel, and the suspension body 100 is moved to the detection area. After the detection is completed, the suspension body 100 is moved to the next link. On the actual processing line, the suspension mechanism 11 and the moving mechanism 12 can be reasonably selected and arranged according to actual conditions. It should be noted that Figure 1B The suspension mechanism 11 and the moving mechanism 12 shown are only examples, and the present disclosure does not limit the specific structures and positions of the suspension mechanism 11 and the moving mechanism 12 .

[0060] The radiation source 2 is arranged at the first side of the detection channel and is used to emit radiation. Figure 1A The first side is the side where the lower side of the detection channel is located. The radiation emitted by the radiation source 2 can penetrate the suspension body 100 and has radioactivity, such as X-rays. During the detection process, it is necessary to prevent the radiation from leaking out of the detection channel.

[0061] The detector 3 is arranged on the second side of the detection channel, and the first side and the second side are two opposite sides of the detection channel. Figure 1A In the embodiment, the second side is the side where the upper side of the detection channel is located. The detector 3 and the radiation source 2 are arranged opposite to each other, and receive the radiation emitted from the radiation source 2 and passing through the suspension 100. After the same radiation passes through different suspensions 100 and is received by the detector 3, the radiation processing system can reflect the different component information of the suspension 100 through the received radiation, for example, the lean meat rate of the suspension 100 can be detected, and the suspension 100 can be graded according to the preset standard.

[0062] like Figure 1A and Figure 1C As shown, the radiation protection structure 4 includes a first radiation protection wall 41, a second radiation protection wall 42 and a protection bottom plate 43, forming a semi-open space, which can prevent radiation from leaking out of the detection channel. At the same time, this structure is suitable for production lines in the form of hanging rails, with high visualization and convenient equipment maintenance.

[0063] In this embodiment, the first radiation shielding wall 41 and the second radiation shielding wall 42 are respectively located at the first side and the second side of the detection channel, that is, the first radiation shielding wall 41 is located at the first side of the detection channel, and the second radiation shielding wall 42 is located at the second side of the detection channel. The first radiation shielding wall 41 and the second radiation shielding wall 42 isolate the detection channel from the outside world, and can prevent radiation from radiating from all around the detection channel, thereby ensuring the safety of the periphery of the detection channel.

[0064] Preferably, an unmanned area of ​​a specific area can be marked out on the periphery of the detection channel to further improve the radiation protection effect and reduce the radiation risk.

[0065] Please continue reading Figure 1C , the protective bottom plate 43 is located between the ray source 2 and the detector 3 in the second direction Y, and is located on the ground of the detection area. It can be understood that when the detection device 1000 is running, the radiation in the detection area is the strongest, and the danger caused by leakage is also the greatest. Providing the protective bottom plate 43 located on the ground of the detection area can effectively prevent the radiation from leaking from the ground of the detection area.

[0066] Figure 2A is a structural diagram of a protective wall according to some exemplary embodiments of the present disclosure; Figure 2B is a partial view of a maze structure of a protective wall according to some exemplary embodiments of the present disclosure.

[0067] like Figure 1C and Figure 2A As shown, at least one of the first radiation shielding wall 41 and the second radiation shielding wall 42 includes n wall panels, and the n wall panels are arranged in sequence along the first direction X, where n is a positive integer. Specifically, the number of wall panels included in the first radiation shielding wall 41 and the second radiation shielding wall 42 may be the same or different, and needs to be flexibly configured according to the production line.

[0068] Preferably, the wall panel can adopt a structural design of food-grade stainless steel wrapped with lead plate. The lead plate can effectively block the radiation, and the food-grade stainless steel can contact the suspension body without contaminating the suspension body, while being easy to clean.

[0069] like Figure 2B As shown, the connection structure between the i-th wall panel 410 and the i+1-th wall panel 410' includes a maze structure, wherein the i-th wall panel 410 and the i+1-th wall panel 410' are any two wall panels adjacent to each other in the first direction X among the n wall panels, 1≤i≤n-1 and i is a positive integer. For example, n is 4, i can be 1, 2 or 3, and i+1 is 2, 3 or 4 accordingly. Since the rays have a certain directionality, the two adjacent wall panels are connected in a maze structure to prevent the rays from leaking out from the gaps between the wall panels. The first radiation protection wall 41 and the second radiation protection wall 42 can be understood as the first line of defense, which can prevent most of the rays from leaking directly, and the maze structure between the wall panels can be understood as the second line of defense, which can further prevent some rays from leaking out from the gaps between the wall panels to achieve a better protection effect.

[0070] In some embodiments, the i-th wall panel 410 includes a first joint surface 411 facing the i+1-th wall panel 410', the i+1-th wall panel 410' includes a second joint surface 412' facing the i-th wall panel 410, the first joint surface 411 and the second joint surface 412' respectively include the shape of multiple broken lines, and the first joint surface 411 and the second joint surface 412' can be joined to each other to form a maze structure.

[0071] It should be emphasized that the maze structure of the present invention is not limited to the shape of multiple broken lines. Other shapes, such as multiple curves, a combination of curves and straight lines, and other similar shapes should be included in the protection scope of this maze structure.

[0072] In some embodiments, each of the first joint surface 411 and the second joint surface 412' includes a first joint sub-surface 4111, a second joint sub-surface 4112 and a third joint sub-surface 4113. Specifically, the first joint sub-surface 4111 of the first joint surface 411 protrudes in a direction toward the second joint surface 412' relative to the third joint sub-surface 4113 of the first joint surface 411, and the second joint sub-surface 4112 of the first joint surface 411 connects the first joint sub-surface 4111 of the first joint surface 411 with the third joint sub-surface 4113 of the first joint surface 411, so that the first joint surface and the second joint surface 412' can be tightly joined together through the maze structure to prevent radiation from leaking out from the gap.

[0073] It is worth noting that each of the first joint surface 411 and the second joint surface 412' may also include more joint sub-surfaces. For example, the first joint surface 411 includes four joint sub-surfaces, and correspondingly, the second joint surface 412' also includes four joint sub-surfaces. In theory, the more complex the shape of the joint surface or the more joint sub-surfaces there are, the more difficult it is for radiation to leak out from the gaps in the wallboard. However, in actual operation, the more complex the shape of the joint surface or the more joint sub-surfaces there are, the higher the requirements for manufacturing process and precision, and the manufacturing cost will increase accordingly. Moreover, when the number of joint sub-surfaces exceeds a certain level, the effect of improving radiation protection is effective.

[0074] Please continue reading Figure 2B In some embodiments, the i-th wall panel 410 further includes a first connection protrusion 413 located on a first wall surface of the i-th wall panel 410, and the first wall surface of the i-th wall panel 410 is a surface of the i-th wall panel 410 that is away from the detection channel. Correspondingly, the i+1-th wall panel 410' further includes a second connection protrusion 414' located on a first wall surface of the i+1-th wall panel 410', and the first wall surface of the i+1-th wall panel 410' is a surface of the i+1-th wall panel 410' that is away from the detection channel, the first connection protrusion 413 is adjacent to the first joint surface 411, and the second connection protrusion 414' is adjacent to the second joint surface 412'.

[0075] In this embodiment, the radiation protection structure 4 also includes a connecting block 44 and a plurality of first connecting members 451, the connecting block 44 includes a plurality of first long holes 441 passing through the connecting block 44, the long axis directions of the plurality of first long holes 441 are parallel to the first direction X, and the plurality of first connecting members 451 are respectively inserted into the plurality of first long holes 441 to connect the i-th wall panel 410 with the i+1-th wall panel 410' through the connecting block 44.

[0076] It can be understood that, through the connection structure of the first connection protrusion 413, the second connection protrusion 414', the connection block 44, the plurality of first connection members 451, and the plurality of first long holes 441, the first connection surface 411 of the i-th wall panel 410 and the second connection surface 412' of the i+1-th wall panel 410' can be firmly and tightly connected together to prevent radiation from leaking out of the gap between the wall panels. The connection structure is arranged on the surface of the wall panel away from the detection channel, which is convenient for operation outside the detection channel.

[0077] Figure 3A is a combined structural diagram of a protective bottom plate 43 and a bottom plate support frame 5 according to some exemplary embodiments of the present disclosure; Figure 3B is a structural diagram of a protective bottom plate 43 according to some exemplary embodiments of the present disclosure; Figure 3C is a structural diagram of a base plate support frame 5 according to some exemplary embodiments of the present disclosure.

[0078] like Figure 3A and 3B As shown, the protective bottom plate 43 includes a first bottom plate 431, a second bottom plate 432 and a third bottom plate 433. Specifically, the second bottom plate 432 and the third bottom plate 433 are arranged on both sides of the first bottom plate 431, wherein a portion of the panel of the first bottom plate 431 facing away from the detection area is connected to the first end surface of the second bottom plate 432 along the second direction Y, and another portion of the panel of the first bottom plate 431 is connected to the first end surface of the third bottom plate 433 along the second direction Y.

[0079] For example, the second bottom plate 432 and the third bottom plate 433 can have exactly the same structure and size, and the panel of the first bottom plate 431 facing away from the detection area and the first end face of the second bottom plate 432 are welded together, and the panel of the first bottom plate 431 facing away from the detection area and the first end face of the third bottom plate 433 are welded together, so that the second bottom plate 432 and the third bottom plate 433 are fixed almost vertically on the panel of the first bottom plate 431 facing away from the detection area.

[0080] In this embodiment, the first end surface of the first bottom plate 431 is attached to the wall surface of the first radiation protection wall 41 facing the detection area, and the second end surface of the first bottom plate 431 is attached to the wall surface of the second radiation protection wall 42 facing the detection area. It can be understood that the first bottom plate 431 is attached to the second radiation protection wall 42 of the first radiation protection wall 41 respectively, which can prevent the radiation in the detection area from leaking out from the gap between the protective bottom plate and the wall plate.

[0081] Please continue reading Figure 3B In some embodiments, the first bottom plate 431 includes a first bottom plate sub-portion 4311, a second bottom plate sub-portion 4312, and a third bottom plate sub-portion 4313. In the second direction Y, the second bottom plate sub-portion 4312 is between the first bottom plate sub-portion 4311 and the third bottom plate sub-portion 4313, and the second bottom plate sub-portion 432 forms a first angle with the first bottom plate sub-portion 431, and the second bottom plate sub-portion 432 forms a second angle with the third bottom plate sub-portion 433. The two ends of the second bottom plate sub-portion 4312 are respectively connected to one end of the second bottom plate 432 and one end of the third bottom plate 433, the other end of the first bottom plate sub-portion 4311 is attached to the wall surface of the first radiation protection wall 41 facing the detection area, and the other end of the third bottom plate sub-portion 4313 is attached to the wall surface of the second radiation protection wall 42 facing the detection area. For example, the first angle can be 90° to increase the contact area of ​​the first bottom plate sub-portion 4311 attached to the first radiation protection wall 41, thereby improving the radiation protection effect. The second angle may also be 90°, and the effect is the same as the first angle, which will not be described again here.

[0082] like Figure 3C As shown, in some embodiments, the detection device 1000 also includes a base plate support frame 5.

[0083] Specifically, at least a portion of the base plate support frame 5 is located between the radiation source 2 and the detector 3 in the second direction Y, and at least a portion of the base plate support frame 5 is located on the ground of the detection area, wherein the base plate support frame 5 includes a first support portion 51, a second support portion 52 and a third support portion 53, and in the second direction Y, the first support portion 51 is between the second support portion 52 and the third support portion 53, the first support portion 51 is used to support the protective base plate 43, the second support portion 52 is used to support the radiation source 2, and the third support portion 53 is used to support the detector 3.

[0084] It can be understood that a wall panel is placed between the first support part 51 and the second support part 52, and a wall panel is placed between the first support part 51 and the third support part 53. The bottom plate support frame 5 makes the protective bottom plate 43, the radiation source 2, the detector 3 and the wall panel a relatively fixed whole.

[0085] For example, a wire tube may be provided at the bottom of the first supporting portion 51 to detect the connection of wires or communication lines on both sides of the channel without exposing the lines to the outside.

[0086] like Figure 3B As shown, the second bottom plate 432 includes a plurality of second long holes 4323 arranged at intervals along the second direction Y, the long axis directions of the plurality of second long holes 4323 are parallel to the third direction Z, and the plurality of second long holes 4323 are used to adjust the position of the second bottom plate 432 in the third direction Z so that the second end surface of the second bottom plate 432 fits the ground. The second end surface of the second bottom plate 432 is opposite to the first end surface of the second bottom plate 432. The third direction Z intersects with the second direction Y and the third direction Z is the direction of the weight line of the suspension body 100.

[0087] The third bottom plate 433 includes a plurality of third long holes (not shown) arranged at intervals along the second direction Y, the long axis directions of the plurality of third long holes are parallel to the third direction Z, and the plurality of third long holes are used to adjust the position of the third bottom plate 433 in the third direction Z so that the second end surface of the third bottom plate 433 is in contact with the ground. The second end surface of the third bottom plate 433 is opposite to the first end surface of the third bottom plate 433.

[0088] Preferably, the second bottom plate 432 and the third bottom plate 433 may have the same structure and size, and the second long hole 4323 and the third long hole may have the same size and arrangement position.

By adjusting the positions of the second and third connecting members connecting the second and third long holes, the second bottom plate 432 and the third bottom plate 433 are made to fit the ground, so as to prevent radiation from leaking out from the gap between the second bottom plate 432 and the ground and / or the gap between the third bottom plate 433 and the ground.

[0090] Figure 4 is a structural diagram of a protective wall baffle 46 according to some exemplary embodiments of the present disclosure.

[0091] like Figure 1C and Figure 4 As shown, in some embodiments, the radiation protection structure 4 further includes a plurality of protective wall baffles 46. Specifically, the plurality of protective wall baffles 46 are arranged in sequence along the first direction X, and are at least arranged on the ground on one side of the detection channel. The protective wall baffles 46 include a first protective baffle 461 and a second protective baffle 462, wherein the first protective baffle 461 is used to contact the lower edge of the wall panel close to the ground, and the second protective baffle 462 is used to contact the ground to prevent radiation from leaking out of the detection channel from the gap between the wall panel and the ground.

[0092] It should be noted that, considering the cost and protection effect, the protective wall baffle 46 does not have to be set on every wall panel in contact with the ground. For example, the wall panel of the detection area is in contact with the protective bottom plate 43 and has a protective function, so the protective wall baffle 46 may not be set. For another example, if the wall panel of the entrance or exit area of ​​the detection channel is far away from the detection area, the protective wall baffle 46 may not be set.

[0093] Figure 5 is a structural diagram of a protective wall support frame 47 according to some exemplary embodiments of the present disclosure.

[0094] like Figure 1C and Figure 5 As shown, in some embodiments, the radiation protection structure 4 further includes a plurality of protection wall support frames 47. The plurality of protection wall support frames 47 are arranged at intervals along the first direction X, and are arranged outside the detection channel and / or inside the detection channel, and are used to support the first radiation protection wall 41 and / or the second radiation protection wall 42. In other words, when supporting the first radiation protection wall 41 and / or the second radiation protection wall 42, the plurality of protection wall support frames 47 can be arranged inside the detection channel or outside the detection channel.

[0095] Specifically, the protective wall support frame 47 includes a support plate 471, a support rod 472 and a support leg 473.

The support rod 472 is fixedly connected to the support plate 471 and extends along the second direction Y. The support leg 473 is connected to the support rod 472, and the support leg 473 is used to contact the ground to provide support for the wall panel.

[0096] like Figure 5 As shown, in some embodiments, the support leg 473 includes a screw rod 4731 arranged along the third direction Z, and the screw rod 4731 is connected to the support rod 472 by a thread to adjust the position of the support leg 473 relative to the support rod 472 in the third direction Z. At least one protective wall support frame 47 includes at least one roller 474, which is arranged on the support rod 472 and arranged side by side with the support leg 473 to reduce the resistance when the wall panel moves.

[0097] For example, there can be one roller 474. When the wall panel needs to be moved, the screw rod 4731 is rotated to raise the support leg 473 and detach it from the ground, and the roller 474 contacts and supports the ground, so that the wall panel can be moved on the ground. When the wall panel needs to be fixed on the ground, the screw rod 4731 can be rotated in the opposite direction, the support leg 473 is lowered and supports the ground, and the roller 474 is detached from the ground, so that the wall panel can be moved and supported.
