Technical Field

[0001] This invention relates to the field of electron accelerator technology, specifically to a support device for an irradiation accelerator. Background Technology

[0002] Patent CN217562256U discloses a height-adjustable electron accelerator irradiation device. The device includes: a constant-temperature shell, inside which a motor accelerator body is installed; a push rod, with a sleeve at its top and a connecting pipe at its top, with a wire connecting the push rod and the sleeve; and a cylinder located at the top of the constant-temperature shell. The advantages are: the cylinder allows adjustment of the height of the motor accelerator body, and the push rod moves up and down accordingly with the motor accelerator body, allowing the push rod to extend and retract within the sleeve. A top ring is installed at the top of the push rod to prevent the wire from getting stuck in the gap between the push rod and the sleeve. A limiting plate is installed at the bottom of the connecting pipe, located in an annular groove, allowing the sleeve to rotate and preventing the wire from getting stuck on the inner wall of the sleeve. A brush prevents dust from entering the sleeve.

[0003] In the prior art, the electron accelerator is installed in the area above the workpiece, and then the electron accelerator irradiates the workpiece. However, the support device on the electron accelerator does not have a corresponding structure for processing the workpiece; it only serves to limit the installation.

[0004] Therefore, a support device for an irradiation accelerator is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a support device for an irradiation accelerator. The stepped mechanism forms a temperature field that descends from left to right through multiple independent temperature control units within the main frame. As the cable passes through the heat-conducting cavity, the temperature decreases step by step, avoiding thermal stress concentration and reducing the risk of material deformation. The annular structure and rubber ring of the heat-conducting cavity can improve heat conduction efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] Preferably, the temperature inside the multiple sets of heat-conducting cavities decreases in an equal step manner from left to right, which facilitates the step-by-step cooling of the cables passing through.

[0013] The supporting and fixing components consist of a main frame, a first water pump, a temperature sensor, a heating wire, a return pipe, a delivery pipe, a heat insulation ring, a heat conduction cavity, a rubber ring, and a folded telescopic membrane.

[0014] Its effect is that the stepped mechanism provides a precise, controllable, uniform, and stable stepped cooling environment, protecting the irradiated cables.

[0015] Preferably, the fixing component is fixedly connected to the side wall of the frame, and a drive water wheel is rotatably connected inside the return pipe of the fixing component. The center of the drive water wheel is fixedly connected to the center of the drive wheel through a transmission shaft. The drive wheel is connected to the driven wheel through a belt.

[0016] Its effect lies in the fact that the fluid kinetic energy recovery design of the fixed component intelligently drives the rotation and coating function of the auxiliary mechanism, reducing energy consumption.

[0017] Preferably, the auxiliary mechanism on the mounting frame includes a receiving ring, with an air guide pipe and a liquid guide pipe fixedly connected to the top of the receiving ring. The top of the liquid guide pipe is connected to the inside of the liquid storage tank. A miniature water pump is bolted to the inside of the liquid storage tank. The outlet of the miniature water pump is connected to the liquid guide pipe. A three-way solenoid valve is connected to the upper end of the air guide pipe. One end of the three-way solenoid valve is connected to an air pump, which is located on the top of the liquid storage tank.

[0022] The friction wheel is connected to the heat insulation ring on the fixed assembly via a folded telescopic membrane.

[0023] Preferably, the heat insulation ring on the fixing component is connected to the heat insulation ring near one end of the fixing component through a folded telescopic membrane.

[0024] Compared with the prior art, the present invention provides a support device for an irradiation accelerator, which has the following advantages:

[0025] 1. This invention uses a drive motor to rotate the drive shaft, and utilizes the symmetrically distributed drive slots and the inclined surface of the embedded rod to make the adjusting block expand or contract synchronously along the limiting rod; the spacing of the stepped mechanism can be adjusted in real time; the length of the cable wrapped by the stepped mechanism can be adjusted, and the length of the cable wrapped in the temperature stepped area between the stepped mechanisms can be adjusted.

[0027] 3. The stepped mechanism in this invention forms a temperature field that descends from left to right in a stepped manner through multiple independent temperature control units in the main frame. When the cable passes through the heat conduction cavity, the temperature decreases step by step, avoiding thermal stress concentration and reducing the risk of material deformation. The annular structure and rubber ring of the heat conduction cavity can improve the heat conduction efficiency.

[0028] 4. In the fixed component of this invention, the water flow in the return pipe drives the water wheel; it is converted into the mechanical energy of the friction wheel, resulting in energy saving effect: reducing additional power consumption.

[0029] 5. The auxiliary mechanism in this invention expands the air bladder with an air pump to make the contact cotton adhere tightly to the cable surface. The micro water pump accurately delivers the antioxidant in the storage tank to the contact point. The rotation of the friction wheel ensures that the coating is evenly distributed. The coating process is carried out synchronously with the cable transmission. At the same time, with the assistance of the stepped mechanism, the coated liquid can be quickly cured on the cable without additional processes, thus improving production efficiency.

[0040] The technical solutions of 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1 - Figure 8 This embodiment of an irradiation accelerator support device includes a mounting frame 1, which is used to mount electron accelerator components.

[0042] Furthermore, such as Figures 1-8 As shown, an adjustment mechanism 2 is fixedly connected to the mounting frame 1. The adjustment mechanism 2 includes a frame 21, which is fixedly connected to the side wall of the mounting frame 1. A drive motor 22 is bolted to the frame 21. The output shaft of the drive motor 22 drives the drive shaft 23 to rotate within the frame 21. Multiple drive slots 24 are embedded in the drive shaft 23. An embedded rod 25 is slidably inserted into the drive slot 24. The embedded rod 25 is rotatably connected to the adjustment block 26. The adjustment block 26 is slidably connected to the outer surface of the limiting rod 27. The limiting rod 27 is fixedly connected to the side wall of the frame 21.

[0043] The number of drive slots 24, embedded rods 25, and adjusting blocks 26 are the same, and multiple sets of drive slots 24 are symmetrically arranged at the left and right ends of the drive shaft 23.

[0044] Among them, the drive motor 22 is controlled to rotate, the drive motor 22 drives the drive shaft 23 to rotate, the drive shaft 23 drives the embedded rod 25 to move through multiple sets of drive grooves 24, the embedded rod 25 pushes the adjustment block 26 to move, the multiple sets of adjustment blocks 26 expand or contract with each other, and the adjustment block 26 drives the multiple sets of stepped mechanisms 3 to move.

[0045] At the same time, such as Figures 1-8 As shown, the adjusting block 26 on the adjusting mechanism 2 is fixedly connected to the stepped mechanism 3. The adjusting mechanism 2 is used to adjust the length between the stepped mechanisms 3, adjust the length between the cables wrapped by the stepped mechanisms 3, and make the length of the cables wrapped in the temperature stepped area between the stepped mechanisms 3 adjustable.

[0046] The stepped mechanism 3 includes a main frame 31. A first water pump 32 is bolted inside the main frame 31. The first water pump 32 is used to draw liquid into the heat conduction chamber 38, and then into the return pipe 35 through the heat conduction chamber 38. The return pipe 35 then delivers the liquid into the main frame 31. A temperature sensor 33 and a heating wire 34 are installed inside the main frame 31. The temperature sensor 33 and the heating wire 34 are used to heat the liquid inside and monitor its temperature. The return pipe 35 and the delivery pipe 36 are fixedly connected to the bottom of the main frame 31. The upper end of the delivery pipe 36 is connected to the outlet end of the first water pump 32. A heat insulation ring is fixedly connected to the bottom of the return pipe 35 and the delivery pipe 36. 37. The rubber ring 39 is made of rubber material and contacts the cable surface to improve the sealing performance between the heat-conducting cavity 38 inside the heat insulation ring 37 and the cable. The heat insulation ring 37 has a heat-conducting cavity 38, which is annular. The bottom of the return pipe 35 and the delivery pipe 36 are connected to the heat-conducting cavity 38. A rubber ring 39 is fixedly connected to the side wall of the heat insulation ring 37. The other end of the heat insulation ring 37 is connected to one end of the folded telescopic membrane 310. The other end of the folded telescopic membrane 310 is fixedly connected to the side wall of the heat insulation ring 37 inside the mating assembly 311. The temperature inside the multiple heat-conducting cavities 38 decreases in a stepped manner from left to right, which facilitates the stepped cooling of the passing cable.

[0047] When irradiating the cable, one end of the cable is passed through the receiving ring 41 and then delivered to the heat insulation ring 37 in the fixing component 312, and then extends outward through multiple sets of heat insulation rings 37 in sequence.

[0048] The temperature of the liquid in each main frame 31 is adjusted by controlling the temperature sensors 33 and heating wires 34 in multiple main frames 31. Then, the liquid is drawn into the heat conduction cavity 38 in the heat insulation ring 37 by the first water pump 32 for heat transfer, so that the temperature in the heat insulation ring 37 is kept at a certain temperature.

[0049] When the adjusting mechanism 2 moves the multiple sets of heat insulation rings 37 to adjust the spacing, the multiple sets of heat insulation rings 37 expand or fold and contract by pulling the multiple sets of folded telescopic membranes 310, so that the channel formed by the multiple sets of heat insulation rings 37 is in a closed state, which facilitates the step-by-step cooling of the cable.

[0050] Furthermore, such as Figures 1-8As shown, the mating assembly 311 and the fixing assembly 312 are composed of a main frame 31, a first water pump 32, a temperature sensor 33, a heating wire 34, a return pipe 35, a delivery pipe 36, a heat insulation ring 37, a heat conduction cavity 38, a rubber ring 39, and a folded telescopic membrane 310.

[0051] The fixed component 312 is fixedly connected to the side wall of the frame 21. A drive water wheel is rotatably connected inside the return pipe 35 inside the fixed component 312. The center of the drive water wheel is fixedly connected to the center of the drive wheel 313 through a transmission shaft. The drive wheel 313 is connected to the driven wheel 49 through a belt 314.

[0052] Furthermore, such as Figures 1-8 As shown, the auxiliary mechanism 4 includes a receiving ring 41. A gas guide pipe 42 and a liquid guide pipe 43 are fixedly connected to the top of the receiving ring 41. The side walls of the gas guide pipe 42 and the liquid guide pipe 43 are fixedly connected to the mounting bracket 1. The top of the liquid guide pipe 43 communicates with the inside of a liquid storage tank 44. A miniature water pump 441 is bolted to the inside of the liquid storage tank 44. The outlet end of the miniature water pump 441 communicates with the liquid guide pipe 43. A three-way solenoid valve 442 is connected to the upper end of the gas guide pipe 42. One end of the three-way solenoid valve 442 is connected to an air pump 45. The air pump 45 is located in... The top of the reservoir 44 is filled with antioxidant liquid. A gear ring 46 is rotatably connected to the side wall of the receiving ring 41. A friction wheel 47 is coaxially connected to the gear ring 46. A drive gear 48 is rotatably connected to the side wall of the receiving ring 41. The drive gear 48 meshes with the gear ring 46. An expansion air bladder 411 is provided on the inner side wall of the receiving ring 41. The expansion air bladder 411 is connected to the air guide tube 42. The lower opening of the liquid guide tube 43 passes through the expansion air bladder 411 and is inserted into the contact cotton 412 on the inner side wall of the expansion air bladder 411.

[0053] In this process, the control air pump 45 draws air into the expansion airbag 411, causing the expansion airbag 411 to expand. The expansion airbag 411 then drives the contact cotton 412 to contact the cable. Then, the micro water pump 441 draws antioxidant liquid and delivers it to the contact cotton 412, causing the contact cotton 412 to absorb the liquid and come into contact with the surface of the cable. This causes the surface of the cable to be coated with antioxidant liquid. The drive water wheel inside the return pipe 35 on the fixing component 312 rotates. The drive water wheel drives the driving wheel 313 to drive the driven wheel 49 to rotate. The driven wheel 49 drives the gear ring 46 to rotate. The gear ring 46 drives the friction wheel 47 to rotate. The friction wheel 47 drives the contact cotton 412 inside to rotate, so that the liquid on the surface of the cable can be evenly distributed.

[0054] Finally, as Figures 1-8As shown, the inner wall of the friction wheel 47 is provided with contact cotton 412; the friction wheel 47 is connected to the heat insulation ring 37 on the fixing component 312 through the folded telescopic membrane 310, and the heat insulation ring 37 on the fixing component 312 is connected to the heat insulation ring 37 near one end of the fixing component 312 through the folded telescopic membrane 310; when the adjustment mechanism 2 changes the overall length, the folded telescopic membrane 310 maintains the integrity and airtightness of the entire cable channel from the inlet of the auxiliary mechanism 4 to the outlet of the stepped mechanism 3.

[0055] like Figures 1-8 As shown, the principle of the irradiation accelerator support device provided in this embodiment is as follows:

[0056] The device is installed in the working environment, and then the electron accelerator on the mounting frame 1 is run to scan the box and irradiate the cable conveyed below. After the cable is processed by the auxiliary mechanism 4, the stepped mechanism 3, and the adjustment mechanism 2, it is conveyed outward.

[0057] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
