Description

Technical Field

[0001] The present invention relates to the field of transmission technology, and in particular to an annular transmission mechanism and a nuclear waste glass solidification molding device. Background Art

[0002] At present, in the existing transmission structure, if it is necessary to realize temperature control of the transmission parts while realizing transmission, it is usually necessary to set up a separate temperature control component and introduce an additional power source to provide operating power for the temperature control component. Moreover, it is necessary to establish a collaborative relationship between transmission and temperature control, which increases the requirements for synchronous collaborative control, which often makes the entire system more complicated.

[0003] The above defects exist in the transmission structure of many industrial application fields such as object transportation, product testing and inspection, material mixing, processing and molding, waste treatment (including nuclear waste glass solidification molding), etc.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0005] The first purpose of the present invention is to provide an annular transmission mechanism that can simultaneously complete temperature control while achieving transmission, and further improves the matching degree between transmission and temperature control. The required power source is also simpler, which is also of positive significance to improving overall compatibility.

[0006] The second purpose of the present invention is to provide a nuclear waste glass solidification and molding device, which can continuously monitor the structural regularity of the molding mold while preparing samples of nuclear waste glass, and at the same time monitor the sample molding situation, thereby greatly improving the sample preparation quality.

[0007] The embodiment of the present invention is achieved as follows:

[0008] A ring transmission mechanism comprises a reference shaft, a ratchet, a swing arm, a blocking arm, a first pawl, a slide rail, a moving part, a driving rod and a linear driver.

[0009] The reference shaft is coaxially fixedly connected to the ratchet, and the reference shaft has a matching end for transmission matching.

[0010] One end of the swing arm is rotatably matched with the reference shaft, and the blocking arm is fixedly connected to the end of the swing arm away from the reference shaft.

[0011] The first pawl is rotationally engaged with an end of the swing arm away from the reference axis, and the first pawl is engaged with a torsion spring so that the first pawl can fit into the ratchet wheel.

[0012] The slide rail is arranged radially along the ratchet wheel, with the slide rail and ratchet wheel spaced apart. The moving member slides in the slide rail and is driven reciprocally by a linear actuator. One end of the drive rod is hinged to the moving member, and the other end is hinged to the end of the swing arm away from the reference axis.

[0013] The blocking arm is equipped with a pressing pump, the pressing portion of which is located on a side of the blocking arm close to the first pawl, and the pressing pump is used to cooperate with a cooling medium circulation pipeline.

[0014] The end of the first pawl is configured as a hook portion, so that when the first pawl reciprocates along the ratchet wheel, the hook portion can intermittently hook the ratchet teeth of the ratchet wheel, thereby driving the ratchet wheel. Alternatively, the end of the first pawl is configured as a pushing end, so that when the first pawl reciprocates along the ratchet wheel, the pushing end can intermittently push the ratchet teeth of the ratchet wheel, thereby driving the ratchet wheel.

[0015] When the first pawl reciprocates along the ratchet wheel, the ratchet teeth of the ratchet wheel can periodically push the first pawl toward the side where the blocking arm is located, so that the first pawl can periodically press the pressing portion.

[0016] Furthermore, a swing arm, a blocking arm, a pressing pump and a driving rod are provided on opposite sides of the ratchet. The annular transmission mechanism also includes: a second pawl.

[0017] The first pawl and the second pawl are respectively arranged on two swing arms on opposite sides of the ratchet. Both the first pawl and the second pawl are in contact with the ratchet.

[0018] The end of any one of the first pawl and the second pawl is constructed as a hook, and the end of the other is constructed as a pushing end, so that the first pawl and the second pawl can alternately drive the ratchet during the reciprocating motion of the moving part along the slide rail.

[0019] Furthermore, the annular transmission mechanism further includes: an annular rotating member, a reference rod, a guide rod, a matching ring, a first seat body and a second seat body.

[0020] The slide rail is arranged along the radial direction of the annular rotating member, and the slide rail and the annular rotating member are spaced apart, and the matching end is transmission matched with the annular rotating member.

[0021] The reference rod is also arranged along the radial direction of the annular rotating member, and the reference rod is arranged in parallel with the slide rail and at intervals. The reference rod is located between the slide rail and the annular rotating member, and the slide rail and the annular rotating member are both arranged at intervals from the reference rod.

[0022] Guide rods are provided on opposite sides of the reference rod, and the plane where the central axes of the two guide rods are located is perpendicular to the rotation axis of the annular rotating member.

[0023] The guide rod is fixedly connected to the reference rod, the central axis of the reference rod is located in the plane where the central axes of the two guide rods are located, and the two guide rods are symmetrically arranged relative to the reference rod.

[0024] The guide rod includes a first rod body, a second rod body, and a third rod body connected in sequence. The two first rod bodies are arranged in parallel, and the two third rod bodies are also arranged in parallel. The spacing between the two first rod bodies is smaller than the spacing between the two third rod bodies. The third rod body is located on the side of the first rod body that is closer to the rotation axis of the annular rotating member, and the spacing between an end of the third rod body that is closer to the first rod body and the rotation axis of the annular rotating member is equal to the radius of the annular rotating member.

[0025] Each guide rod is slidably engaged with a mating ring. The first seat body is rotatably engaged with the mating ring on a side away from the annular rotating member, with the rotational axis of the first seat body being parallel to the rotational axis of the annular rotating member. The second seat body is engaged with the mating ring on a side closer to the annular rotating member, and is fixedly engaged with the mating ring along the circumference of the rotational axis of the first seat body.

[0026] The second seat is provided with a distance sensor.

[0027] The reference rod is slidably matched with a transmission block, which is fixedly connected to the moving part. The transmission block is fixedly connected to an extension rod, which is arranged perpendicular to the reference rod and passes through the first base body. The extension rod is slidably matched with the first base body.

[0028] The transmission block has a first motion range, a second motion range and a third motion range.

[0029] When the transmission block is located in the first movement range, the matching ring is located on the first rod body, and the distance sensors of the second seat body are arranged facing each other.

[0030] When the transmission block is located in the second movement range, the matching ring is located on the second rod body, and the second seat body deflects with the matching ring, so that the distance sensor deflects toward the side where the third rod body is located.

[0031] When the transmission block is located in the third motion interval, the matching ring is located on the third rod body, and the distance sensors of the second seat body are arranged facing each other.

[0032] Furthermore, any one of the two first bases is provided with a docking rod, and the other is provided with a docking contact. The docking rod and the docking contact are both made of conductive material, and are respectively connected to two poles of the detection circuit.

[0033] When the transmission block is located in the first motion range, the docking rod and the docking contact point are in contact and electrically connected.

[0034] Furthermore, the guide rod is provided with a clearance gap, which extends from the side of the guide rod away from the annular rotating member to the side of the guide rod close to the annular rotating member, and the clearance gap extends from one end of the guide rod along the length direction of the guide rod and extends to the other end of the guide rod.

[0035] The matching ring is fixedly connected with a connecting tube, which passes through the matching ring and is located in the clearance gap.

[0036] The first seat body is rotatably matched with an end of the connecting cylinder away from the annular rotating member. The first seat body has an inner cavity in which a transmission gear is rotatably matched.

[0037] A mating tube is disposed within the connecting tube. Along the axial direction of the connecting tube, the mating tube slides within the connecting tube. Along the circumferential direction of the connecting tube, the mating tube is fixedly mated to the connecting tube. The mating tube has an internal thread and extends beyond the end of the connecting tube distal from the first seat. The second seat is fixedly connected to the end of the mating tube.

[0038] The transmission gear is fixedly connected to a transmission shaft, which passes through the first seat body and extends into the connecting cylinder, and then extends into the matching cylinder. The transmission shaft has an external thread, and the transmission shaft is threadedly matched with the matching cylinder.

[0039] The extension rod passes through the inner cavity, is provided with a rack, and is in transmission cooperation with the transmission gear.

[0040] When the transmission block is located in the first motion range, the second seat body is flush with the annular rotating member.

[0041] When the transmission block is located in the third motion interval, the second seat body is located on a side of the annular rotating member close to the guide rod, and the second seat body is spaced apart from the annular rotating member.

[0042] Furthermore, the second base is provided with a heat dissipation component for cooling the distance sensor, and the heat dissipation component is connected to the cooling medium circulation pipeline.

[0043] A nuclear waste glass solidification and molding device comprises a melting mechanism, a discharging mechanism, a molding die and the above-mentioned annular transmission mechanism.

[0044] The rotation axis of the annular rotating member of the annular transmission mechanism is arranged along the vertical direction. The surface of the annular rotating member is provided with an installation groove, and the forming mold is accommodated in the installation groove.

[0045] The melting mechanism is used to heat the nuclear waste glass to a molten state, and the discharging mechanism is used to put the nuclear waste glass in a molten state in the melting mechanism into a forming mold.

[0046] The annular transmission mechanism is used to transport the forming molds to the discharging mechanism in sequence, so that the forming molds can receive the nuclear waste glass in a molten state.

[0047] Furthermore, at most one forming mold moves to the area between the two third rods at the same time.

[0048] When the transmission block just enters the second motion range from the first motion range, a forming mold is located in the area between the two third rods. When the transmission block is in the third motion range, the corresponding forming mold is located in the middle area between the two third rods.

[0049] The beneficial effects of the technical solutions of the embodiments of the present invention include:

[0050] The annular transmission mechanism provided by the embodiment of the present invention only requires a single power source, namely the linear drive. When the driving speed of the linear drive is slow, that is, when the reciprocating speed of the moving part along the slide rail is slow, the rotation speed of the ratchet and the reference shaft is also slow, and the transmission speed is at a relatively slow level. At this time, the frequency at which the first pawl presses the pressing part is also correspondingly low, and the pressure pump also delivers the liquid medium slowly, which is exactly compatible with the current slow transmission speed. Conversely, when the driving speed of the linear drive is fast, the pressure pump also delivers the liquid medium quickly.

[0051] In general, the annular transmission mechanism provided by the embodiment of the present invention can achieve transmission while also synchronously completing temperature control, and further improves the matching degree between transmission and temperature control. The required power source is also simpler, which is also of positive significance for improving overall coordination.

[0052] The nuclear waste glass solidification and molding device provided in the embodiment of the present invention can continuously monitor the structural regularity of the molding mold while preparing samples of the nuclear waste glass, and simultaneously monitor the sample molding situation, thereby greatly improving the sample preparation quality.

DETAILED DESCRIPTION

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0071] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0072] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0073] The terms "first", "second", "third", etc. are only used for distinction and description and should not be understood as indicating or implying relative importance.

[0074] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0075] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0076] In order to overcome the shortcomings of the existing technology, please refer to Figure 1-Figure 2 This embodiment provides a ring transmission mechanism, which includes: a reference shaft 100, a ratchet 110, a swing arm 120, a blocking arm 121, a first pawl 130, a slide rail 140, a moving part 141, a driving rod 142 and a linear driver 200.

[0077] The reference shaft 100 is coaxially fixedly connected to the ratchet 110, and the reference shaft 100 has a mating end for transmission cooperation. The mating end of the reference shaft 100 can be used for transmission cooperation with other components to achieve transmission.

[0078] One end of the swing arm 120 is rotatably engaged with the reference shaft 100, and the blocking arm 121 is fixedly connected to one end of the swing arm 120 away from the reference shaft 100. Optionally, the blocking arm 121 extends along the circumference of the ratchet 110, and the blocking arm 121 is spaced apart from the ratchet 110.

[0079] The first pawl 130 is rotatably engaged with one end of the swing arm 120 away from the reference shaft 100 . The first pawl 130 is engaged with a torsion spring (not shown in the figure). Under the elastic force of the torsion spring, the first pawl 130 is always in contact with the ratchet teeth of the ratchet wheel 110 .

[0080] Slide rail 140 is disposed radially of ratchet 110, spaced from ratchet 110, and fixed relative to reference shaft 100. A moving member 141 slidably engages slide rail 140 and is reciprocally driven by linear actuator 200. A drive rod 142 is hinged at one end to moving member 141 and at the other end to the end of swing arm 120 distal from reference shaft 100.

[0081] The barrier arm 121 is equipped with a pressing pump 150. The pressing portion 151 of the pressing pump 150 is located on the side of the barrier arm 121 close to the first pawl 130. The pressing pump 150 is used to cooperate with the cooling medium circulation pipe 160. The cooling medium circulation pipe 160 is used to transport the cooling medium, which can be a liquid medium. The cooling medium circulation pipe 160 is used to be connected to the temperature control component to circulate the liquid medium to the temperature control component, thereby achieving cooling. The temperature control component can be installed in the relative motion position in the annular transmission mechanism, and can also be installed in other positions that require cooling. A one-way valve can be provided in the cooling medium circulation pipe 160 to avoid accidental backflow of the liquid medium. The pressing pump 150 is used for directional transportation of the liquid medium.

[0082] When the linear actuator 200 drives the moving member 141 to reciprocate along the slide rail 140 , the driving rod 142 reciprocally drives the swing arm 120 , thereby causing the first pawl 130 to reciprocate along the ratchet wheel 110 .

[0083] The end of the first pawl 130 may be configured as a hook portion 170, so that when the first pawl 130 reciprocates along the ratchet 110, the hook portion 170 can intermittently hook the ratchet teeth of the ratchet 110, thereby driving the ratchet 110. In addition, the end of the first pawl 130 may also be configured as a pushing end 180, so that when the first pawl 130 reciprocates along the ratchet 110, the pushing end 180 can intermittently push the ratchet teeth of the ratchet 110, thereby driving the ratchet 110.

[0084] When the first pawl 130 reciprocates along the ratchet 110, the ratchet teeth of the ratchet 110 can periodically push the first pawl 130 toward the side where the blocking arm 121 is located, so that the first pawl 130 can periodically squeeze the pressing part 151, thereby using the pressing pump 150 to continuously transport the liquid medium in the cooling medium circulation pipe 160.

[0085] Only a single power source, the linear actuator 200, is required. When the linear actuator 200 is driven at a slow speed—that is, when the reciprocating motion of the moving member 141 along the slide rail 140 is slow—the ratchet 110 and the reference shaft 100 rotate at a slow speed, resulting in a relatively slow transmission speed. At this point, the frequency with which the first pawl 130 presses the pressing portion 151 is also correspondingly low, and the press pump 150 delivers the liquid medium at a slow rate, which is precisely aligned with the current slow transmission speed. Conversely, when the linear actuator 200 is driven at a fast speed, the press pump 150 also delivers the liquid medium at a fast speed.

[0086] In general, the annular transmission mechanism provided in this embodiment can achieve transmission while also synchronously completing temperature control, and further improves the matching degree between transmission and temperature control. The required power source is also simpler, which is also of positive significance for improving overall coordination.

[0087] Optionally, the ratchet 110 may be provided with a swing arm 120 , a blocking arm 121 , a pressing pump 150 and a driving rod 142 on opposite sides thereof. The annular transmission mechanism further includes a second pawl 190 .

[0088] The first pawl 130 and the second pawl 190 are respectively provided on two swing arms 120 on opposite sides of the ratchet 110. The first pawl 130 and the second pawl 190 are both in contact with the ratchet 110.

[0089] The end of any one of the first pawl 130 and the second pawl 190 is constructed as a hook 170, and the end of the other is constructed as a pushing end 180, so that when the moving part 141 reciprocates along the slide rail 140, the first pawl 130 and the second pawl 190 can alternately drive the ratchet 110.

[0090] With this design, the ratchet 110 can continue to rotate in a directional manner, thereby achieving continuous transmission.

[0091] Further, please combine Figure 3-Figure 6 The annular transmission mechanism further includes: an annular rotating member 300, a reference rod 400, a guide rod 500, a matching ring 600, a first base body 700 and a second base body 800.

[0092] The slide rail 140 is arranged along the radial direction of the annular rotating member 300, and the slide rail 140 is spaced apart from the annular rotating member 300, and the engaging end is in driving engagement with the annular rotating member 300. A portion of the slide rail 140 extends beyond the range of the annular rotating member 300.

[0093] The reference rod 400 is also arranged along the radial direction of the annular rotating member 300, and the reference rod 400 is parallel, juxtaposed and spaced apart from the slide rail 140. The reference rod 400 is located between the slide rail 140 and the annular rotating member 300, and both the slide rail 140 and the annular rotating member 300 are spaced apart from the reference rod 400.

[0094] The reference shaft is in transmission cooperation with the annular rotating member 300. Specifically, the reference shaft can be in transmission cooperation with the inner ring side of the annular rotating member 300, and the transmission ratio between the two can be flexibly selected according to actual needs.

[0095] Guide rods 500 are provided on opposite sides of the reference rod 400 . The plane where the central axes of the two guide rods 500 lie is perpendicular to the rotation axis of the annular rotating member 300 .

[0096] The two end portions of the guide rod 500 are respectively fixedly connected with a fixing rod 410, and the fixing rod 410 is arranged perpendicular to the reference rod 400. The guide rod 500 and the reference rod 400 are fixedly connected through the fixing rod 410. The central axis of the reference rod 400 is located within the plane where the central axes of the two guide rods 500 are located, and the two guide rods 500 are symmetrically arranged relative to the reference rod 400.

[0097] The guide rod 500 includes a first rod body 510 , a second rod body 520 and a third rod body 530 which are connected in sequence.

[0098] The two first rods 510 are arranged in parallel and spaced apart. The two third rods 530 are also arranged in parallel and spaced apart. The distance between the two first rods 510 is smaller than the distance between the two third rods 530 .

[0099] The third rod 530 is located on the side of the first rod 510 close to the rotation axis of the annular rotating member 300, and the distance between the end surface of the third rod 530 close to the first rod 510 and the rotation axis of the annular rotating member 300 is equal to the radius of the annular rotating member 300.

[0100] The second rod 520 and the first rod 510 extend beyond the range of the annular rotating member 300. The included angle between the second rod 520 and the first rod 510 can be selected to be 45°.

[0101] Each guide rod 500 is slidably fitted with a fitting ring 600 .

[0102] The first base 700 is rotatably engaged with the side of the engagement ring 600 away from the annular rotating member 300 . The rotation axis of the first base 700 relative to the engagement ring 600 is parallel to the rotation axis of the annular rotating member 300 .

[0103] The second seat body 800 is fitted to a side of the fitting ring 600 close to the annular rotating member 300 . The second seat body 800 is fixedly fitted to the fitting ring 600 along the circumferential direction of the rotation axis of the first seat body 700 .

[0104] The second base 800 is provided with a distance sensor 810 .

[0105] The reference rod 400 is slidably fitted with a transmission block 420, which is fixedly connected to the moving member 141. That is, when the moving member 141 is driven by the linear actuator 200, the transmission block 420 is also synchronously driven, and the transmission block 420 moves back and forth along the reference rod 400.

[0106] Extension rods 430 are fixedly connected to opposite sides of the transmission block 420. The extension rods 430 are arranged perpendicular to the reference rod 400. The extension rods 430 are located on the side of the reference rod 400 away from the annular rotating member 300 and are spaced apart from the reference rod 400. The extension rods 430 pass through the first base body 700 and are slidably engaged with the first base body 700. The extension rods 430 on both sides of the transmission block 420 are coaxially arranged.

[0107] The mating ring 600 is sleeved on the guide rod 500, with the inner sidewall of the mating ring 600 in contact with the outer sidewall of the guide rod 500. The connection between the first rod 510 and the second rod 520, as well as the connection between the second rod 520 and the third rod 530, are smoothed to facilitate smooth movement of the mating ring 600 between the first rod 510, the second rod 520, and the third rod 530.

[0108] When the transmission block 420 moves, the transmission block 420 drives the first base 700 through the extension rod 430 , and the first base 700 drives the matching ring 600 to move along the guide rod 500 , thereby further driving the second base 800 .

[0109] The transmission block 420 has a first motion range, a second motion range, and a third motion range.

[0110] When the transmission block 420 is located in the first movement range, the matching ring 600 is located on the first rod body 510, and the matching ring 600 moves within the range of the first rod body 510. At this time, the distance between the two second base bodies 800 is the shortest, and the side surfaces of the second base bodies 800 on which the distance sensors 810 are provided are arranged facing each other. That is to say, at this time, the distance sensors 810 of the two second base bodies 800 are arranged facing each other, and the distance sensors 810 of the two second base bodies 800 are both used to detect the distance between the second base bodies 800.

[0111] When the transmission block 420 is in the second movement range, the mating ring 600 is located on the second rod 520 and moves within the range of the second rod 520. At this time, the direction of the mating ring 600 is deflected relative to when it is on the first rod 510, and the second base 800 also deflects with the mating ring 600, which causes the direction of the distance sensor 810 to deflect toward the side where the third rod 530 is located. In this embodiment, the deflection angle is 45°. Figure 7 shown.

[0112] When the transmission block 420 is located in the third movement range, the mating ring 600 is located on the third rod 530, and the mating ring 600 moves within the range of the third rod 530. At this time, the orientation of the mating ring 600 is the same as when it is on the first rod 510, that is, in this state, the distance sensor 810 of the second base 800 is also arranged facing each other.

[0113] The annular rotating member 300 may be used to install or cooperate with other components, and may be flexibly configured according to actual needs, and this application does not impose any specific restrictions.

[0114] For example, the annular rotating member 300 can be used to transport objects, in which case the annular transmission mechanism drives the transport mechanism. The annular rotating member 300 can also be used to mount a detection probe and a stirring rod to perform detection work during a stirring state, in which case the annular transmission mechanism drives the detection equipment. However, this is not a limitation. The specific application scenario of the annular rotating member 300 can be flexibly selected based on actual needs and is not specifically limited in this application.

[0115] With this design, while transmission is being achieved, the distance sensor 810 provided on the second base 800 can also be used to detect components near the annular rotating member 300 .

[0116] Specifically, when the linear actuator 200 drives the moving part 141, when the linear actuator 200 is in different driving states, the extended length of the power shaft of the linear actuator 200 is determined, and the position of the matching ring 600 on the guide rod 500 is also determined. At this time, based on the distance value detected by the distance sensor 810, it can be determined whether the position of the component facing the distance sensor 810 has shifted, or whether the shape of the corresponding component has been deformed.

[0117] Optionally, the distance sensor 810 may be a laser sensor.

[0118] Furthermore, any one of the two first base bodies 700 is provided with a docking rod 900 , and the other one is provided with a docking contact point (not shown in the figure).

[0119] The docking rod 900 and the docking contacts are both made of conductive materials, and are connected to two poles of a detection circuit (not shown in the figure) respectively.

[0120] When the transmission block 420 is located in the first movement range, the docking rod 900 is in contact with the docking contact point and is electrically connected.

[0121] With this design, when the transmission block 420 is in the first movement range, as long as the detection circuit detects that the docking rod 900 is electrically conductive with the docking contact, it indicates that the docking rod 900 is in successful contact with the docking contact. At this time, the distance between the two first base bodies 700 and the distance between the two second base bodies 800 are both constant, and the distance values detected by the two distance sensors 810 should correspond to them, thereby achieving calibration of the two distance sensors 810.

[0122] In this embodiment, please combine Figure 8The guide rod 500 is provided with a clearance gap 540, which passes through the side of the guide rod 500 away from the annular rotating member 300 to the side of the guide rod 500 close to the annular rotating member 300, and the clearance gap 540 extends from one end of the guide rod 500 along the length direction of the guide rod 500 and extends to the other end of the guide rod 500.

[0123] The matching ring 600 is fixedly connected to a connecting tube 610, which passes through the matching ring 600 and is located in the clearance gap 540. The outer diameter of the connecting tube 610 is smaller than the width of the clearance gap 540.

[0124] The two ends of the connecting tube 610 are sealed by sealing plates.

[0125] The first base 700 is rotatably engaged with the end of the connecting tube 610 away from the annular rotating member 300. The first base 700 has an inner cavity, in which a transmission gear 710 is rotatably engaged.

[0126] A mating cylinder 620 is disposed within the connecting cylinder 610. The mating cylinder 620 is coaxially disposed with the connecting cylinder 610. The outer diameter of the mating cylinder 620 is smaller than the inner diameter of the connecting cylinder 610. The end of the mating cylinder 620, which is adjacent to the first seat 700, has an annular flange 621. The annular flange 621 is located on the outer wall of the mating cylinder 620 and is in contact with the inner wall of the connecting cylinder 610.

[0127] Along the axial direction of the connecting cylinder 610 , the matching cylinder 620 is slidably fitted to the connecting cylinder 610 via the annular flange 621 . Along the circumferential direction of the connecting cylinder 610 , the matching cylinder 620 is fixedly fitted to the connecting cylinder 610 via the annular flange 621 .

[0128] The mating tube 620 has an internal thread and passes through the sealing plate at one end of the connecting tube 610 away from the first seat body 700 and extends outside the connecting tube 610 . The second seat body 800 is fixedly connected to the end of the mating tube 620 .

[0129] The transmission gear 710 is fixedly connected to a transmission shaft 720. The transmission shaft 720 passes through the first base body 700 and the sealing plate of the connecting cylinder 610 near one end of the first base body 700. The transmission shaft 720 extends into the connecting cylinder 610 and rotatably engages with the first base body 700 and the connecting cylinder 610. The transmission shaft 720 extends into the engaging cylinder 620.

[0130] The transmission shaft 720 has an external thread, and the transmission shaft 720 is threadedly matched with the matching cylinder 620 .

[0131] The extension rod 430 passes through the inner cavity. The extension rod 430 has a rack (not shown in the figure) arranged along the length direction thereof. The extension rod 430 is in transmission cooperation with the transmission gear 710 .

[0132] When the transmission block 420 is in the first motion range, the annular flange 621 is located at the end of the connecting cylinder 610 away from the first seat body 700, and most of the matching cylinder 620 extends out of the connecting cylinder 610. At this time, the second seat body 800 is farthest from the guide rod 500, and the second seat body 800 is flush with the annular rotating member 300. Figure 4 As shown, the second base 800 is located outside the range of the annular rotating member 300 , and the surface of the second base 800 close to the first base 700 is flush with the surface of the annular rotating member 300 close to the first base 700 .

[0133] When the transmission block 420 is located in the second movement range, taking the movement of the transmission block 420 to the third movement range as an example, at this time, the distance between the first base body 700 and the transmission block 420 gradually increases, the extension rod 430 and the first base body 700 slide relative to each other, and the rack of the extension rod 430 drives the transmission gear 710. Therefore, the transmission shaft 720 rotates, driving the matching cylinder 620 toward the connecting cylinder 610, and the second base body 800 moves toward the first base body 700.

[0134] After the transmission block 420 enters the third motion range, the distance between the second base 800 and the first base 700 reaches the minimum value, and the second base 800 moves to the side of the annular rotating member 300 close to the guide rod 500, and the second base 800 is spaced apart from the annular rotating member 300. Figure 9 and Figure 10 At this time, the second seat body 800 enters the range of the annular rotating member 300.

[0135] With this design, when the transmission block 420 enters the second range from the first range of motion, the distance sensor 810 has just begun to deflect. At this point, the distance sensor 810 is aligned with the edge of the annular rotating member 300, allowing it to detect whether the annular rotating member 300 has shifted, thus providing an additional reference for the inspection of other components. If the annular rotating member 300 is detected to have shifted at the beginning, the subsequent inspection results of other components mounted on the annular rotating member 300 will be inaccurate. If the annular rotating member 300 has not shifted, the inspection results will be more valuable when other components mounted on the annular rotating member 300 are detected to have shifted.

[0136] Optionally, the second base 800 is provided with a heat dissipation assembly (not shown) for cooling the distance sensor 810, and the heat dissipation assembly is connected to the cooling medium circulation pipe 160. In other words, while the transmission is in progress, the distance sensor 810 can also be cooled by the pressure pump 150 to ensure the detection accuracy of the distance sensor 810.

[0137] It is understandable that the cooling medium circulation pipe 160 can also be connected to heat dissipation components at other locations, and is not limited to this, and can be flexibly selected according to actual needs.

[0138] As an application example of the annular transmission mechanism, this embodiment also provides a nuclear waste glass solidification and molding device, which is intended to provide a more intuitive explanation of one of the specific applications of the annular transmission mechanism, and is not intended to limit the application scope of the annular transmission mechanism. The application scope of the annular transmission mechanism is not limited to this and can be flexibly selected according to actual needs.

[0139] Nuclear waste glass is highly radioactive, toxic, and has a long half-life, making its final safe disposal extremely difficult and posing a series of scientific, technological, and engineering challenges. The ultimate safe disposal of high-level liquid waste is directly related to the sustainable development of the nuclear industry and environmental protection. Currently, vitrification technology is commonly used to treat high-level liquid waste both domestically and internationally. This method, which converts high-level liquid waste into a stable and reliable glass solidification body followed by deep geological disposal, appears to be a relatively feasible and acceptable method. Deep geological disposal involves treating high-level liquid waste with special solidification methods and then encapsulating it in a disposal container. A multi-barrier system is used to effectively isolate radionuclides from the biosphere for a long-term, safe disposal.

[0140] However, before high-level liquid waste glass enters its final geological repository, its radionuclide leaching behavior in the corresponding hydrological environment must be evaluated. The nuclear waste glass solidification and molding device is used to prepare small samples of nuclear waste glass to facilitate leaching experiments.

[0141] Please combine Figure 11-13 The nuclear waste glass solidification and molding device includes: a melting mechanism 2100, a discharging mechanism 2200, a molding mold 2300 and the above-mentioned annular transmission mechanism.

[0142] At this time, the rotation axis of the annular rotating member 300 of the annular transmission mechanism is arranged in the vertical direction. A mounting groove (not shown in the figure) is opened on the surface of the annular rotating member 300, and the forming mold 2300 is accommodated in the mounting groove.

[0143] The melting mechanism 2100 is used to heat the nuclear waste glass to a molten state, and the discharging mechanism 2200 is used to put the nuclear waste glass in a molten state in the melting mechanism 2100 into the forming mold 2300.

[0144] The bottom of the melting mechanism 2100 is supported by a support column 2110 . The annular rotating member 300 is disposed around a support column 2110 at the bottom of the melting mechanism 2100 . A portion of the annular surface of the annular rotating member 300 is located below the discharging mechanism 2200 .

[0145] The annular transmission mechanism uses a circular rotating member 300 to sequentially transport the forming molds 2300 to the underside of the discharge mechanism 2200, allowing the forming molds 2300 to receive the molten nuclear waste glass. Rotating the annular rotating member 300 transports the forming molds 2300 to the discharge mechanism 2200 one by one, allowing each mold 2300 to collect the molten nuclear waste glass one by one, thereby allowing the forming molds 2300 to prepare small samples of the nuclear waste glass.

[0146] At the same time, at most one forming mold 2300 moves to the area between the two third rods 530 .

[0147] When the transmission block 420 just enters the second motion range from the first motion range, there is a forming mold 2300 in the area between the two third rods 530. When the transmission block 420 is in the third motion range, the corresponding forming mold 2300 is located in the middle area between the two third rods 530, such as Figure 14 shown.

[0148] It should be noted that the “middle area” here does not specifically refer to the middle point of the area between the two third rods 530 , but refers to a range, a range close to the middle of the area between the two third rods 530 .

[0149] After the linear actuator 200 completes one reciprocating drive of the moving member 141 , one molding die 2300 just leaves the area between the two third rods 530 , and another molding die 2300 just enters the area between the two third rods 530 .

[0150] The length of the third rod 530 is greater than the diameter of the forming mold 2300. When a forming mold 2300 is located in the middle area between two third rods 530, both ends of the third rod 530 extend beyond the corresponding range of the forming mold 2300.

[0151] With this design, each time the linear actuator 200 completes a reciprocating drive operation on the moving part 141, it can complete the inspection of a forming mold 2300. When the forming mold 2300 has not yet received molten glass, it can be used to detect whether the shape of the forming mold 2300 is regular and has not undergone any deformation, or to detect whether the forming mold 2300 is accurately installed in the installation slot. Once the forming mold 2300 has received all the glass, the annular rotating member 300 can be controlled to continue rotating, so that the distance sensor 810 can be used to detect whether there is any glass overflow or residual outside the forming mold 2300.

[0152] In this embodiment, the distance between the guide rod 500 and the upper surface of the annular rotating member 300 is greater than the height of the forming mold 2300. When the mating ring 600 is located on the third rod 530, the height of the distance sensor 810 is lower than the opening of the forming mold 2300. The specific distance between the height of the distance sensor 810 and the opening of the forming mold 2300 can be flexibly set according to actual needs.

[0153] Optionally, there may be multiple distance sensors 810 on the second base 800, and the multiple distance sensors 810 are arranged along the axial direction of the connecting cylinder 610. In this way, the detection range of the forming mold 2300 can be increased in the height direction.

[0154] It is understood that the melting mechanism 2100 is provided with a matching heating component, a temperature measuring component, and a control component for controlling the heating component and the temperature measuring component, which will not be described in detail in this application. The heating component of the melting mechanism 2100 can adopt an electric heating method, but is not limited to this, and the heating method can be flexibly selected according to actual conditions.

[0155] The forming mold 2300 may be cylindrical or rectangular, but is not limited thereto. The specific shape of the forming mold 2300 may be flexibly selected according to actual needs.

[0156] The inner liner of the melting mechanism 2100 can be made of high-purity alumina or zirconia-toughened alumina. The inner cavity of the melting mechanism 2100 can be set to be wide at the top and narrow at the bottom. The discharge mechanism 2200 is set at the bottom of the melting mechanism 2100 so that the discharge mechanism 2200 can fully discharge the molten glass in the melting mechanism 2100.

[0157] A heat insulating layer is provided on the outside of the melting mechanism 2100. The heat insulating layer may be made of porous alumina, mullite or high temperature resistant silicon aluminum filler, but is not limited thereto.

[0158] When preparing small samples for a nuclear waste glass solidification molding device, the following process can be used (for example only and not limited to):

[0159] S1. The nuclear waste glass is placed into the melting mechanism 2100. The melting mechanism 2100 heats the glass to a preset temperature at a preset heating rate using the heating component of the melting mechanism 2100 and maintains the temperature for a preset time. The preset heating rate, temperature, and time can be flexibly set according to actual needs.

[0160] S2. Use the discharge mechanism 2200 to put the glass in the melting mechanism 2100 into the forming mold 2300, and use the annular rotating part 300 of the annular transmission mechanism to transport the forming molds 2300 one by one to the discharge mechanism 2200, and use the discharge mechanism 2200 to put the glass in the melting mechanism 2100 into each forming mold 2300.

[0161] S3. After the sample is sufficiently cooled, the small sample is taken out from the molding mold 2300.

[0162] Among them, you can flexibly choose whether to anneal the glass according to actual needs.

[0163] When annealing is selected, a heating mechanism for annealing can be provided on the surface of the annular rotating member 300 to directly heat the forming mold 2300 , thereby heating the glass inside the forming mold 2300 , thereby completing the heating operation of the annealing process.

[0164] To sum up, the annular transmission mechanism provided in the embodiment of the present invention can achieve transmission while also synchronously completing temperature control, and further improves the matching degree between transmission and temperature control. The required power source is also simpler, which is also of positive significance for improving overall coordination.

[0165] The nuclear waste glass solidification and molding device provided in the embodiment of the present invention can continuously monitor the structural regularity of the molding mold 2300 while preparing samples of the nuclear waste glass, and simultaneously monitor the sample molding conditions, thereby greatly improving the sample preparation quality.

[0166] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
