Description

Technical Field

[0001] The utility model relates to the field of pipeline cables for high-radiation environments, and specifically to an integrated structure pipe cable for radiation-resistant water and power transmission. Background Technique

[0002] With the progress of society, especially the rapid development of scientific progress, all walks of life in society have achieved remarkable results. Among them, cables, as signal transmission media and power sources, have played a very important role.

[0003] In the operating environment of high-radiation equipment represented by the nuclear industry, not only must the operation of the equipment be ensured, but also the protection against nuclear radiation is required to be strict. Among them, how to ensure that in a high-temperature and airtight environment, the high temperature generated by the operation of equipment in a radiation environment can be reduced, especially in the most efficient way to remove or connect the cooling equipment and the connection and disconnection of other group components represented by wires, has always been a problem studied in the high-radiation field.

[0004] For the cooling of the operating environment and equipment in the existing high-radiation field, common methods include controlling the temperature of the peripheral environment and physically cooling the equipment internally through an independent cold air or water cooling system.

[0005] The above traditional cooling systems or equipment can play a good role in temperature conditions to a certain extent. However, due to safety considerations, the high-radiation environment generally adopts maximum control of the occupied space or volume compression. For an independent temperature-conditioning system, although it can play a good role in temperature regulation, it also occupies a certain amount of space. At the same time, in order to reduce the construction difficulty of the temperature-regulating equipment and improve the cooling effect, a large-diameter pipeline and a small number of bends are usually adopted. This not only increases the occupation of space, but also cannot achieve good precise temperature regulation for some narrow and relatively airtight internal spaces and corners of equipment.

[0006] In the entire high-radiation environment, cables or pipelines, as important media for power or signal transmission, are spread throughout all links of equipment and the high-radiation environment like the capillaries of the human body.

[0007] Therefore, how to effectively reduce the temperature of equipment in a high-radiation environment without occupying a large amount of space or being able to precisely adjust the temperature is a problem worthy of study. Content of the Utility Model

[0030] The following further describes the present utility model in conjunction with the drawings and embodiments.

[0031] First embodiment:

[0032] SeeFigures 1-4 As shown, the integrated structure cable for radiation-resistant water and power transmission provided by the present utility model includes a cable body 1 in which multiple conducting cores 2 are arranged, and a liquid delivery pipe 3 is provided. The liquid delivery pipe 3 is used to conduct a low-temperature deionized water source or other cooling medium sources. The conducting cores 2 are distributed around the liquid delivery pipe 3, forming an integrated electrical and liquid conduction system. First connectors 5 and second connectors 6 are respectively connected to both ends of the cable body 1. These two connectors can be movably connected and matched. Both the first connector 5 and the second connector 6 are provided with fluid channels 9 communicating with the liquid delivery pipe 3 and electrical connection heads 7 electrically connected to the conducting cores 2. And fluid channels 9 communicating with the liquid delivery pipe 3 are provided on both the first connector 5 and the second connector 6, as well as electrical connection heads 7 electrically connected to the first connector 5. The first connector 5 and the second connector 6 are movably connected and matched, and the connection of the first connector 5 and the second connector 6 can be used to extend the cable body 1, assist in electrically connecting the conducting cores 2, and conduct the liquid in the liquid delivery pipe 3; when two cable bodies 1 are connected, the first connector 5 and the second connector 6 can be correspondingly arranged. After the first connector 5 on the previous cable body 1 and the second connector 6 on the next cable body 1 are plugged and connected, the extension and conduction of the liquid delivery pipe 3 can be realized through the conduction of the fluid channels 9, the flow of the cooling liquid can be realized, and the generated heat can be effectively taken away to prevent overheating; through the electrical connection of the electrical connection heads 7, the electrical connection of the conducting cores 2 on the two cable bodies 1 is realized, ensuring the smooth conduction of the current, that is, the overall extension of the cable body 1 is realized;

[0033] Generally speaking, through the connection of the first connector 5 and the second connector 6, the overall length of the cable body 1 is extended. After entering the high-radiation environment, the device can be quickly docked with the temperature control system distributed in the high-radiation environment, realizing the dual functions of providing power and transporting the temperature control medium at the same time. The electrical connection of the electrical connection heads 7 ensures the reliability of the electrical connection. At the same time, the connection of the fluid channels 9 to the liquid delivery pipe 3 can assist in effectively conducting the cooling liquid, thereby taking away the heat generated during the use of the conducting cores 2 and preventing overheating of the conducting cores 2 during use, achieving the coordinated operation of the electrical system and the cooling system. At the same time, the characteristics of wide distribution of the cable also play an auxiliary role in the temperature control of the high-radiation environment while transmitting the medium; compared with independent systems such as separate cooling equipment, the use space and the equipment installation and use costs are greatly reduced.

[0034] In the structure of the cable body 1, the cable body 1 includes a covering layer 101 and an inner filling layer 102. The inner filling layer 102 is filled between the conducting core 2 and the liquid delivery pipe 3, enabling the liquid delivery pipe 3, the conducting core 2, and the cable body 1 to form a tight combination. Moreover, the conducting core 2 and the liquid delivery pipe 3 can be protected by the inner filling layer 102 and the covering layer 101. Further, the conducting cores 2 are evenly distributed on the outer side of the liquid delivery pipe 3. When the conducting core 2 is working, the coolant flows through the liquid delivery pipe 3, which can effectively carry away the heat generated by the conducting core 2, prevent overheating, and maintain the stable operation of the system. Additionally, the inner filling layer 102 includes a radiation-resistant inner layer close to the covering layer 101, the material of which is butyne rubber, and non-metallic wires are also arranged inside it, enabling the device to transport high-pressure water. The pipe wall of the liquid delivery pipe 3 includes a rubber layer, a winding layer, and a braiding layer arranged in sequence from the inside to the outside. Among them, the number of winding layers is odd, and the number of braiding layers is even.

[0035] In a specific embodiment, the inner diameter of the liquid delivery pipe 3 is 19 mm, the outer diameter is 31 - 30 mm, and it can comprehensively transport a pressure of 3 - 4.0 MPa, with a burst pressure of 12 MPa. The voltage of the conducting core 2 is 220 volts. After calculation, the radiation-resistant dose is 10 to the power of 5 - 6².

[0036] Furthermore, a toughness strip 4 extending along the length of the cable body 1 is provided inside the inner filling layer 102, and the toughness strip 4 can enhance the overall toughness and durability.

[0037] The second embodiment is different from the first embodiment in the following characteristics:

[0038] The electrical connector 7 is a plug and a socket, and the plug and the socket are respectively arranged on the first connector 5 and the second connector 6. The electrical connection ends of the electrical connector 7 are electrically connected to the conducting cores 2 at both ends. When the socket and the plug are inserted into each other, the first connector 5 and the second connector 6 approach each other, enabling the electrical connection ends of the conducting cores 2 to achieve stable electrical connection through the electrical connector 7, thus ensuring the smooth conduction of current at both ends. This configuration effectively connects different parts of the conducting core 2 and maintains the overall electrical connectivity and reliability of the system.

[0039] In the conduction structure of the four-line fluid passage 9 of the first connector 5 and the second connector 6, a convex tube head 502 and a connecting concave head 601 communicating with the fluid passage 9 are respectively provided on the first connector 5 and the second connector 6. The convex tube head 502 is inserted and fitted with the connecting concave head 601, and the conduction of the fluid passage 9 is realized by the insertion and fitting of the convex tube head 502 and the connecting concave head 601. Further, an annular groove 503 for assisting the installation of the sealing ring is provided on the outer side of the convex tube head 502. When the convex tube head 502 is inserted into the connecting concave head 601, the sealing ring can be installed inside the annular groove 503, and the annular groove 503 is used to limit the sealing ring. After the convex tube head 502 is connected to the connecting concave head 601, the sealing ring is used to assist in sealing between the convex tube head 502 and the connecting concave head 601. Moreover, the opening end of the convex tube head 502 is chamfered, which is beneficial to the insertion of the convex tube head 502 into the connecting concave head 601. In a specific structure, the connecting concave head 601 is a stepped groove, the stepped part at the inner end of the connecting concave head 601 is correspondingly arranged with the movable end of the convex tube head 502, and an annular gasket 10 is provided. The end face of the annular gasket 10 facing the convex tube head 502 is correspondingly arranged, that is, a corresponding chamfer is also provided, and the annular gasket 10 is used to assist in sealing to avoid liquid leakage.

[0040] The third embodiment is different from the second embodiment in that:

[0041] The second connector 6 is provided with a locking assembly 8 for locking with the first connector 5. By using the locking assembly 8, the second connector 6 and the first connector 5 can be locked, so that the second connector 6 and the first connector 5 are in a more stable state and not easily fall off after being inserted, ensuring the reliability of the sealing between the convex tube head 502 and the connecting concave head 601. In the specific structure of the locking assembly 8, a plugging groove 501 is provided on the outer side of the convex tube head 502. The locking assembly 8 includes a sliding frame 803 that slides with the second connector 6. During the sliding installation of the sliding frame 803, a guiding strip 602 is provided on the outer side of the second connector 6, and the sliding frame 803 is slidably connected to the outer side of the guiding strip 602. The side of the sliding frame 803 facing the second connector 6 is an open structure, and its open end is slidably matched with the guiding strip 602. A thrust spring 802 for pushing the sliding frame 803 to slide towards the connecting concave head 601 is provided on the guiding strip 602. The thrust spring 802 plays a role in pushing the sliding frame 803, and the sliding frame 803 is pressed by using the elasticity of the thrust spring 802. In the natural state, the locking of the convex tube head 502 is ensured. A limiting block 801 corresponding to the convex tube head 502 is slidably connected to the connecting concave head 601. An inner ring surface 804 corresponding to the limiting block 801 and an opening corresponding to the electrical connecting head 7 are provided on the sliding frame 803 away from its open side. The inner wall of the inner ring surface 804 is inclined, that is, the side wall of the inner ring surface 804 corresponding to the limiting block 801 is in an inclined surface or an arc surface. After the inclined surface or arc surface contacts the outer end of the limiting block 801, all the plurality of limiting blocks 801 can be pushed to move towards the inner end of the connecting concave head 601 at the same time, and the limiting block 801 is pushed to slide towards the inner end of the connecting concave head 601 to lock the plugging groove 501. During the locking process, the inner ring surface 804 on the sliding frame 803 cooperates with the corresponding limiting block 801, so that the limiting block 801 is inserted into the inner side of the inner ring surface 804, ensuring that the plugging groove 501 is firmly locked and preventing the second connector 6 and the first connector 5 from falling off due to vibration or other external factors after being inserted. This design ensures the reliability and stability of the connection. When disassembling the first connector 5 and the second connector 6, pulling the sliding frame 803 to move against the elasticity of the thrust spring 802, then the inner ring surface 804 moves away from the limiting block 801, releasing the limitation on the limiting block 801. The limiting block 801 can slide on the connecting concave head 601, so as to slide out from the inside of the plugging groove 501, releasing the limitation on the plugging groove 501, and pulling the convex tube head 502 out from the inside of the connecting concave head 601 to realize the separation of the first connector 5 and the second connector 6. The operation is simple and convenient, and the use effect is good. After releasing the sliding frame 803, the self-resetting of the sliding frame 803 can be realized by using the elasticity of the thrust spring 802.

[0042] In a preferred embodiment, a rubber ring corresponding to the limiting block 801 is provided on the outer side of the connecting recess 601. The elasticity of the rubber ring is used to limit the limiting block 801 to avoid the slipping-off of the limiting block 801. When pulling out the convex pipe head 502 from the inside of the connecting recess 601, it is also necessary to overcome the elasticity of the rubber ring. In addition, a chamfer is provided at the inner end edge of the limiting block 801.

[0043] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
