In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0039] like Figures 1-7 As shown, this embodiment proposes a two-way pneumatic transmission system for radioactive rabbit racing, including a first transceiver 1, a second transceiver 2, a transmission tube 3, a sample box 11, and a gas supply mechanism. The transmission tube 3 includes two sections of pipe made of conductive material and one end of pipe made of insulating material. A magnet is provided on the sample box 11. By setting up the gas supply mechanism, the first transceiver 1, and the second transceiver 2, bidirectional transmission of the sample box between the first transceiver 1 and the second transceiver 2 can be realized during use. It is simple and convenient to operate, eliminates the need for manual sample transportation, and greatly reduces the harm of radiation to workers.

[0040] Two sections of conductive material pipes are connected to the first transceiver 1 and the second transceiver 2 respectively. An insulating material pipe is connected between the two sections of conductive material pipes. A first airbag 12 is installed at both ends of the sample box 11. The conductive material pipes can work with the magnet on the sample box 11 to decelerate the sample box 11 before it enters the interior of the first transceiver 1 and the second transceiver 2.

[0041] The sample box 11 is equipped with a first airbag 12 at both ends. The hemispherical first airbag 12 installed at both ends of the sample box 11 can also guide the sample box 11 when it passes through the inside turning part of the transfer tube 3, preventing the sample box 11 from getting stuck at the turning point of the transfer tube 3. At the same time, the hemispherical first airbag 12 can also buffer the sample box 11 when it turns, reducing the impact force of the sample box 11 on the inner wall of the transfer tube 3.

[0042] Both the first transceiver device 1 and the second transceiver device 2 include a housing 101 connected to the transmission tube 3. The front of the housing 101 has a first groove 102 that cooperates with the transmission tube 3 and the sample box 11. A buffer assembly 13 that cooperates with the first airbag 12 is installed inside the first groove 102. By setting the first airbag 12 and the buffer assembly 13, they can cooperate with the sample box 11 after it has been decelerated by the hysteresis effect, and buffer it when the sample box 11 enters the first transceiver device 1 and the second transceiver device 2, so as to avoid the problem of sample damage due to excessive impact force.

[0043] The buffer assembly 13 includes a hydraulic buffer 131 installed inside the first groove 102. One end of the hydraulic buffer 131 is connected to a mounting plate 132 that is slidably installed inside the first groove 102. A second airbag 133 is fixedly installed on the mounting plate 132. Both the first airbag 12 and the second airbag 133 are hollow hemispherical structures. The mounting plate 132 facilitates the installation of the second airbag 133. The hydraulic buffer 131 and the second airbag 133 work together with the first airbag 12 to buffer the airbag entering the first groove 102. Moreover, when the hemispherical first airbag 12 and the second airbag 133 come into contact with each other, they deform and dissipate force simultaneously, thereby preventing the sample box 11 from being bounced into the transfer tube 3.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, a further step is to install an inlet / outlet channel 103 through the top of the housing 101, communicating with the interior of the first groove 102. A sealing cap is movably installed at the top of the inlet / outlet channel 103, and a handle is installed on the top of the sealing cap. A through hole is provided through the side wall of the housing 101 to cooperate with the gas supply device. It should be noted that the through hole facilitates connection with the first gas pipe 7 and the second gas pipe 8. The first groove 102 facilitates the installation of the buffer assembly 13 and the placement of the sample box 11. The inlet / outlet channel 103 facilitates the placement of the sample box 11 into or out of the first groove 102. The sealing cap facilitates the closure of the inlet / outlet channel 103.

[0045] like Figure 5 , Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, the sample box 11 further includes a first box body 111 and a second box body 112 connected by threads. Both the first box body 111 and the second box body 112 are hollow structures. A soft pad 113 is installed inside each of the first box body 111 and the second box body 112, and a second groove 114 is formed on the pad 113. It should be noted that the pad 113 and the second groove 114, together with the first box body 111 and the second box body 112, can better protect the transmitted irradiated sample. The threaded connection between the first box body 111 and the second box body 112 facilitates the removal of the irradiated sample from inside.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, a ring-shaped proximity switch 5 for monitoring the position of the sample box 11 is further installed on the outside of the transmission tube 3, and several ring-shaped proximity switches 5 are configured. It should be noted that by setting the ring-shaped proximity switches 5, the position of the sample box 11 can be monitored, and when the sample box 11 passes two ring-shaped proximity switches 5, the transmission speed of the sample box 11 inside the transmission tube 3 can be calculated based on time and distance.

[0047] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the air supply mechanism further includes an air pump 4. The air outlet of the air pump 4 is connected to a first air pipe 7 and a second air pipe 8 via a three-way connector 6. The ends of the first air pipe 7 and the second air pipe 8 away from the three-way connector 6 are respectively connected to the first transceiver device 1 and the second transceiver device 2. A first valve 9 is installed on the first air pipe 7, and a second valve 10 is installed on the second air pipe 8. By setting up the air pump 4, the three-way connector 6, the first air pipe 7, and the second air pipe 8, the second valve 10 can be closed and the first valve 9 opened during use to allow the air pump to supply air. 4. The three-way connector 6 and the first air pipe 7 supply air to the first transceiver device 1, and the sample box 11 in the first transceiver device 1 is transferred to the first transceiver device 1 through the transfer pipe 3. Similarly, the second valve 10 is opened and the first valve 9 is closed, and the air pump 4 and the second air pipe 8 can supply air to the second transceiver device 2 to transport the sample box 11 in the second transceiver device 2 to the inside of the first transceiver device 1. During use, the sample box 11 can be transferred bidirectionally between the first transceiver device 1 and the second transceiver device 2 without the need for manual sample transportation, which greatly reduces the radiation hazard to the staff.

[0048] Specifically, during operation / use of this radioactive transceiver bidirectional pneumatic transmission system: First, open the sealing cover at the top of the inlet / outlet channel 103 on the first transceiver device 1. Then, place the sample box 11 inside the first groove 102. At this time, close the sealing cover on the inlet / outlet channel 103. Next, close the second valve 10 and open the first valve 9 on the first air pipe 7. Then, open the sealing cover at the top of the inlet / outlet channel 103 on the second transceiver device 2. At this time, start the air pump 4 to supply air to the first transceiver device 1 through the three-way connector 6 and the first air pipe 7, thus transmitting the sample box 11 inside the first transceiver device 1 through... The transmission tube 3 transmits to the interior of the second transceiver 2. When it is necessary to transport the sample box 11 in the second transceiver 2 to the first transceiver 1, the second valve 10 is opened and the first valve 9 is closed. The inlet and outlet channel 103 on the second transceiver 2 is covered with a sealing cap. The air pump 4 is started to supply air to the second transceiver 2 through the three-way connector 6 and the second air pipe 8, so that the sample box 11 in the second transceiver 2 can be transported to the interior of the first transceiver 1. When the sample box 11 enters the interior of the first transceiver 1 and the second transceiver 2, it will be buffered by the first airbag 12 and the buffer component 13. Example

[0049] like Figure 1 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the sample box 11 further includes a shuttle body 121, a pressure cap 122 is installed at one end of the shuttle body 121, a target holder 123 is installed through the inside of the pressure cap 122, and a groove for placing the target material is opened at the top of the target holder 123. A cavity 124 is opened at the other end of the shuttle body 121. Heating rods that cooperate with the cavity 124 are installed inside the first transceiver device 1 and the second transceiver device 2. A sealing ring 125 is provided at the connection between the shuttle body 121 and the pressure cap 122. It should be noted that the sealing ring 125 can seal the connection between the shuttle body 121 and the pressure cap 122, and the groove can facilitate the placement of the target material.

[0050] Specifically, the working principle of this radioactive rabbit bidirectional pneumatic transmission system is as follows: When in use, the target material is clamped onto the pressure cover 122 through the groove, and then the pressure cover 122 is installed on the shuttle body 121. Before or after transmission, the heating rod can extend into the interior of the shuttle body 121 through the cavity 124 to heat the target material on the target holder 123.
