Description

Technical Field

[0001] The invention relates to the technical field of linear accelerator production equipment, and in particular to a linear electron accelerator under-beam production monitoring device. Background Art

[0002] A linear accelerator usually refers to an accelerator that uses a high-frequency electromagnetic field for acceleration, and the trajectory of the accelerated particles is a straight line. A high-frequency linear accelerator is referred to as a linear accelerator. It refers to a device that accelerates charged particles using a high-frequency electric field distributed along a straight track. According to the type of accelerated particles, it can be divided into electron linear accelerators, proton linear accelerators, heavy ion linear accelerators and superconducting linear accelerators. Electron linear accelerators can use traveling waves or standing waves to accelerate particles. When traveling waves are used for acceleration, the structure can be designed to be equal impedance or equal gradient type. The equal impedance type is a uniform acceleration structure, that is, the dimensions of the structure remain unchanged along the axis, which is convenient for design and manufacture. The disadvantage is that the loss of microwave power in the structure is uneven. For longer linear accelerators, it is not easy to control the temperature of the structure along the axis. The equal gradient acceleration structure avoids this disadvantage. The cost is that the structural dimensions along the axis change slowly, making the design and manufacture more complicated. Among them, linear electron accelerators are often used in linear electron accelerator beam production monitoring devices during the production process.

[0003] The existing technology has the following problems:

[0004] 1. Traditional monitoring devices cannot be cleaned or cooled. Long-term use of monitoring devices will generate some heat, which may affect the normal use of the monitoring devices. Dust is easily accumulated on the monitoring surface, which will affect the clarity of monitoring.

[0005] 2. The protective mechanism of traditional monitoring devices has a simple structure and single function. The wind drives the broken particles to hit the monitoring surface, and the broken particles cannot be processed. At the same time, the lack of lighting function causes the monitoring screen to be blurred at night, affecting the monitoring effect. Summary of the invention

[0023] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0024] 1. The present invention provides a linear electron accelerator beam production monitoring device, which adopts a No. 1 air duct, a No. 1 fan, a fixed shell, a water tank, a water pump, a No. 2 water pipe, a nozzle, a No. 2 fan, and a No. 2 air duct. The No. 1 fan can extract the air near the monitor through the No. 1 air duct and transport it to the fixed shell. The water pump transports the water in the water tank to the nozzle through the No. 2 water pipe. The nozzle sprays water to reduce dust while reducing the internal air temperature of the fixed shell. The No. 2 fan extracts the gas with a lower temperature in the fixed shell and transmits it to the surface of the monitor through the No. 2 air duct to cool the surface of the monitor.

The present invention provides a linear electron accelerator beam production monitoring device, which adopts the cooperation of a circulation pipe, a rectangular filter, a cross filter, a triangular block, and a winding rod. Part of the water flow sprayed by the nozzle will directly enter the circulation pipe, and part of the water flow will contact the triangular block. The water flow will be guided by the triangular block, and the water flow will enter the groove. As the water flow in the groove increases, the water flow in the groove is in a moving state, so that some linear impurities in the water flow will be entangled on the surface of the winding rod.

The lighting lamp can illuminate when the light is dim, and the lighting range is expanded by the reflector, which solves the problem that the protective mechanism of the traditional monitoring device has a simple structure and a single function, and lacks a lighting function, resulting in a blurred monitoring screen at night, affecting the monitoring effect, thereby achieving the effect of improving the practicality of the protective mechanism.

[0027] 4. The present invention provides a linear electron accelerator beam production monitoring device, which adopts a trapezoidal shell, an arc-shaped elastic plate, a cross elastic sheet, a hole plate, an arc-shaped dividing block, an intercepting elastic pad, and a hole plate body. The broken small particles will enter the trapezoidal shell through the hole plate, and the arc-shaped elastic plate and the cross elastic sheet will alleviate the force generated by the impact of the broken small particles. After the broken small particles rebound, the intercepting elastic pad will intercept the broken small particles, reducing the circulation of the broken small particles, solving the problem that the wind drives the broken small particles to collide with the monitoring surface and the broken small particles cannot be processed, thereby achieving the effect of reducing the impact of the broken small particles on the monitoring device.

[0037] The present invention is further described in detail below in conjunction with embodiments:

[0038] Example 1

[0039] like Figure 1-8 As shown, the present invention provides a linear electron accelerator beam production monitoring device, including a monitoring device 1, a mounting plate 2 is arranged on the left side of the monitoring device 1, a cooling and dust removal mechanism 3 is arranged on the right side of the mounting plate 2, the cooling and dust removal mechanism 3 includes a fixed shell 34, a water tank 38 is fixedly connected to the top of the fixed shell 34, a No. 2 water pipe 40 is arranged on both sides of the water tank 38, the other end of the No. 2 water pipe 40 extends to the inside of the fixed shell 34 and is fixedly connected to a nozzle 41, the monitoring device 1 includes a protective mechanism 11, the protective mechanism 11 includes a protective shell 111, a guide block 115 is fixedly connected to the bottom of the protective shell 111, a placement groove is opened inside the protective shell 111, and a lighting lamp 113 is arranged on the left side of the inner wall of the placement groove.

[0040] In this embodiment, the guide block 115 can guide the circulating air, and the lighting lamp 113 can provide lighting when the light is dim, which can improve the clarity of monitoring to a certain extent. The No. 2 water pipe 40 can transport the water in the water tank 38 to the nozzle 41, and the water is sprayed through the nozzle 41 to perform dust reduction operations on the air entering the fixed shell 34. Since the temperature of the water is relatively low, the air temperature inside the fixed shell 34 is reduced.

[0041] Example 2

[0042] like Figure 1-8As shown, based on Example 1, the present invention provides a technical solution: preferably, a No. 1 water pipe 36 is provided on the back of the fixed shell 34, and the other end of the No. 1 water pipe 36 is fixedly connected to the back of the water tank 38, and a water pump 39 is provided on the surface of the No. 1 water pipe 36 and the No. 2 water pipe 40 and located outside the fixed shell 34, and a filter plate 35 is provided on the inner wall side of the fixed shell 34, and the filter plate 35 includes a fixed plate 352.

[0043] In this embodiment, when the water pump 39 provided on the surface of the No. 1 water pipe 36 is started, the water inside the fixed shell 34 can be transported to the water tank 38 through the No. 1 water pipe 36, thereby achieving the effect of recycling water.

[0044] The interior of the fixed plate 352 is fixedly connected to a circulation pipe 351, the inner wall of the circulation pipe 351 is fixedly connected to a cross filter 354, the inner wall of the circulation pipe 351 is fixedly connected to a rectangular filter 353, the bottom of the rectangular filter 353 extends to the outside of the fixed plate 352, the top of the circulation pipe 351 is fixedly connected to a dividing block 355, the dividing block 355 includes a triangular block 3551, the surface of the triangular block 3551 is fixedly connected to an elastic block 3552, the surface of the elastic block 3552 is provided with a groove, the inner wall of the groove is fixedly connected to a rubber particle 3553, and the surface of the rubber particle 3553 is fixedly connected to a winding rod 3554.

[0045] When water flows through the filter plate 35, the water flows mixed with impurities such as dust. Part of the water flows directly into the circulation pipe 351, and part of the water flows into contact with the triangular block 3551. The triangular block 3551 guides the water flow so that the water flows into the groove. As the water flow inside the groove increases, the water flow inside the groove is in motion, so that some linear impurities in the water flow will be entangled on the surface of the winding rod 3554. Finally, this part of the water will enter the circulation pipe 351, and the water flow entering the circulation pipe 351 will flow downward. In the process of flowing inside the circulation pipe 351, impurities in the water will be filtered through the rectangular filter mesh 353 and the cross filter mesh 354.

[0046] Example 3

[0047] like Figure 1-8 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a buffer block 116 is fixedly connected to the left side of the guide block 115, a reflective plate 114 is fixedly connected to the inner wall of the placement groove, a trapezoidal block 112 is fixedly connected to the surface of the protective shell 111, the trapezoidal block 112 includes a trapezoidal shell 1121, the bottom of the trapezoidal shell 1121 is fixedly connected to the top of the protective shell 111, and an arc-shaped elastic plate 1122 is fixedly connected to the inner wall side of the trapezoidal shell 1121.

[0048] The bottom of the arc-shaped elastic plate 1122 is fixedly connected to a cross elastic sheet 1123, the bottom of the cross elastic sheet 1123 is fixedly connected to the bottom of the inner wall of the trapezoidal shell 1121, and a hole plate 1124 is fixedly connected to the side of the inner wall of the trapezoidal shell 1121 and located above the arc-shaped elastic plate 1122. The hole plate 1124 includes a hole plate body 1127, the top of the hole plate body 1127 is fixedly connected to an arc-shaped dividing block 1125, and the bottom of the hole plate body 1127 is fixedly connected to a blocking elastic pad 1126.

[0049] In this embodiment, the setting of the reflective plate 114 can improve the lighting range, and the setting of the buffer block 116 can improve the service life of the guide block 115 to a certain extent. The broken particles will enter the trapezoidal shell 1121 through the orifice plate 1124, and the broken particles will contact the arc-shaped elastic plate 1122, and then squeeze the cross elastic sheet 1123. The rebound force of the arc-shaped elastic plate 1122 and the cross elastic sheet 1123 can alleviate the impact force of the broken particles, which may cause the broken particles to rebound. After the broken particles rebound, they are blocked by the blocking elastic pad 1126, so that some of the broken particles cannot flow to the outside.

[0050] Example 4

[0051] like Figure 1-8 As shown, based on Example 1, the present invention provides a technical solution: preferably, a No. 1 air duct 31 is provided inside the fixed shell 34, a No. 2 air duct 43 is provided inside the fixed shell 34, a No. 2 base plate 33 is fixedly connected to the bottom of the fixed shell 34, and a monitor 12 is provided at the top of the inner cavity of the protective shell 111.

[0052] The bottom of the monitor 12 is fixedly connected to a base 13 , and a bottom plate 14 is provided at the bottom of the base 13 . One end of the first air duct 31 and the second air duct 43 both extend above the first bottom plate 14 , and a first fan 32 is provided on the surface of the first air duct 31 .

[0053] The surface of the No. 2 air duct 43 is provided with a No. 2 fan 42. The bottoms of the No. 1 and No. 2 fans 32 and 42 are fixedly connected to the top of the No. 2 base plate 33. The left side of the No. 2 base plate 33 is fixedly connected to the right side of the mounting plate 2. The left side of the No. 1 base plate 14 is fixedly connected to the right side of the mounting plate 2. A cooling plate 37 is provided above the water tank 38.

[0054] In this embodiment, the setting of the refrigeration plate 37 reduces the temperature of the water stored in the water tank 38, thereby improving the cooling efficiency to a certain extent. When the No. 1 fan 32 is started, the air near the monitor 12 can be drawn through the No. 1 air duct 31 and transmitted to the inside of the fixed shell 34. When the No. 2 fan 42 is started, the cooler air in the fixed shell 34 can be drawn out through the No. 2 air duct 43 and transmitted to the surface of the monitor 12, thereby cooling the monitor 12.

[0055] The working principle of the linear electron accelerator beam production monitoring device is described in detail below.

[0056] like Figure 1-8 As shown, when the No. 1 fan 32 is started, the air near the monitor 12 can be extracted through the No. 1 air duct 31 and transmitted to the inside of the fixed shell 34. At this time, by controlling the water pump 39 set on the surface of the No. 2 water pipe 40, the No. 2 water pipe 40 can transport the water in the water tank 38 to the nozzle 41, and the water is sprayed by the nozzle 41 to perform dust reduction operations on impurities in the air, so that the water flow mixed with impurities flows through the filter plate 35, part of the water flow will directly enter the circulation pipe 351, and part of the water flow will contact the triangular block 3551, and the triangular block 3551 will guide the water flow, so that the water flow will enter the groove. As the water flow in the groove continues to increase, the water flow in the groove is in a moving state, so that some of the linear impurities in the water flow will be wrapped around the surface of the winding rod 3554, and finally this part of the water will enter the circulation pipe 351, and the water flow entering the circulation pipe 351 will flow downward. During the flow inside the circulation pipe 351, impurities in the water will be filtered through the rectangular filter 353 and the cross filter 354. When the No. 2 fan 42 is started, the cooler air inside the fixed shell 34 can be drawn out through the No. 2 air duct 43 and transmitted to the surface of the monitor 12 to cool the monitor 12. The lighting lamp 113 can play a lighting role when the light is dim, and the reflector 114 increases the lighting range. The broken particles will enter the trapezoidal shell 1121 through the orifice plate 1124, and then contact the arc-shaped elastic plate 1122, and then squeeze the cross elastic sheet 1123. The rebound force of the arc-shaped elastic plate 1122 and the cross elastic sheet 1123 will alleviate the impact force of the broken particles, which may cause the broken particles to rebound. After the broken particles rebound, they are blocked by the blocking elastic pad 1126, so that some of the broken particles cannot flow to the outside.

[0057] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
