Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, and in particular to an electronic bin structure applied to a rotary guide tool in a high temperature environment. Background Art

[0002] The electronic compartment structure of the rotary steerable drill bit is an important component of the drilling tool. It contains a variety of precision electronic components and sensors to achieve the guidance and control functions of the drill bit. The electronic compartment usually contains data processors, MEMS rate gyroscopes, three-axis gravity accelerometers and other devices. These devices work together to measure and control the position, speed and direction of the drill bit.

[0003] The existing electronic warehouse structure is often simple in structure, and mostly adopts a closed shell, and a plurality of components are installed in the shell. However, in actual use, the components inside this structure are often damaged by the influence of the rotary guide tool. This is because as the rotary guide tool continues to drill, the rotary guide tool will inevitably generate jitter stress during the rotation process, and these jitter stresses are transmitted to the electronic warehouse structure, causing the components inside to be unable to work under a stable working condition, thereby greatly affecting its working state, and causing the reliability of the structure to be greatly limited. At the same time, since the electronic warehouse adopts a closed structure, it is difficult to dissipate the heat generated by the internal electronic components in time, resulting in heat accumulation in the electronic warehouse structure. In addition, the internal space of the existing electronic warehouse structure is compact, and the number of components installed inside is large. At the same time, the wiring harnesses are intricate, which further causes the internal heat flux density of the electronic warehouse to be large, causing the components inside to fail and be damaged under high temperature and heat, thereby affecting the normal use of the electronic warehouse structure. Summary of the invention

[0004] The purpose of the present invention is to provide an electronic bin structure for a rotary guide tool used in a high-temperature environment, so as to ensure that the components in the electronic bin structure will not be affected by the external influence of the tool during normal operation, so that the components in the electronic bin are always working under stable working conditions. At the same time, the heat dissipation performance of the electronic bin structure is improved so that the internal heat can be dissipated in time in a high-temperature environment, so that it can work stably and normally even in a harsh environment.

[0005] The present invention is achieved through the following technical solutions: An electronic bin structure for a rotary guide tool in a high temperature environment, comprising an outer bushing connected to the rotary guide tool on the outside, an inner bin body rotatably connected inside the outer bushing, a cold storage cavity being arranged in the middle of the inner bin body, electronic cavities being respectively arranged at the top and bottom of the cold storage cavity, a cold medium storage being arranged in the cold storage cavity, the top and bottom of which both penetrate into the corresponding electronic cavity, a plurality of wiring harness grooves arranged around the cold medium storage being arranged above and below the outer periphery, wherein the wiring harness groove located above the outer periphery of the cold medium storage is used for routing and arranging the wiring harness of the electronic instrument in the electronic cavity at the upper part of the cold storage cavity, and the wiring harness groove located below the outer periphery of the cold medium storage is used for routing and arranging the wiring harness of the electronic instrument in the electronic cavity at the lower part of the cold storage cavity; The inner walls of the two electronic cavities are provided with fluid channels surrounding the electronic cavities, and the fluid channels are connected to the cold medium storage via a medium circulation pipe. The medium circulation pipe is used to transport the cooling medium in the cold medium storage to the fluid channels on the inner walls of the two electronic cavities, so as to realize cooling and heat dissipation of the interior of the two electronic cavities.

[0006] This solution divides the electronic bin into an outer sleeve and an inner bin body, and the inner bin body and the outer sleeve are rotatably connected. When the outer sleeve rotates with the rotary guide tool, the electronic bin inside it does not rotate accordingly, so that the inner bin body remains in a stationary state when the external rotary guide tool rotates, thereby providing a stable working environment for the internal electronic components, reducing the vibration and stress caused by rotation, thereby improving the service life and reliability of the electronic components, thereby ensuring the stable operation of the electronic bin in the rotary guide tool; At the same time, the present invention provides a cold storage chamber in the middle of the inner compartment body, and a cold medium storage device is provided in the cold storage chamber, and electronic chambers are provided at the upper and bottom of the cold storage chamber respectively, so that the two electronic chambers are arranged close to the cold storage chamber, so that the cold medium storage device provides a cold source for the two electronic chambers, and then the heat in the two electronic chambers is quickly transferred to the cold storage chamber, so that the cold medium storage device absorbs the heat, and at the same time, fluid channels are provided on the inner walls of the two electronic chambers, and the fluid channels are connected to the cold medium storage device through a medium circulation pipe, so that the cold medium in the cold medium storage device enters the fluid channel through the medium circulation pipe for circulation, so that the heat generated by the electronic components in the electronic chamber is quickly absorbed by the circulation of the cold medium, thereby realizing active cooling and heat dissipation of the electronic chamber, realizing direct and efficient cooling of the electronic components, ensuring that the electronic components in the electronic chamber are always maintained within a relatively constant and safe operating temperature range, and ensuring their stable operation. At the same time, in this scheme, a heat barrier layer is formed between the inner walls of the electronic cavity through the circulation of the cold medium in the fluid channel. While dissipating and absorbing the heat inside the electronic cavity, it effectively isolates the external high temperature and high heat from being conducted into the electronic cavity, which limits the operation of its internal components. It is further necessary to emphasize here that the technical solution is provided with a plurality of harness grooves arranged around the upper and lower periphery of the cold medium storage. The arrangement of the harness grooves facilitates the arrangement of the axes of the harnesses of the electronic components in the two electronic cavities, so that they pass through the harness grooves in sequence, thereby avoiding the intertwining of the harnesses, thereby realizing the arrangement of the harnesses inside the electronic compartment, ensuring that the internal space of the electronic cavity is reasonable and conducive to heat dissipation. At the same time, when the harness passes through the harness groove, since it is in direct contact with the outside of the cold medium storage, the cold medium storage can also dissipate heat and cool the harness, thereby further realizing efficient heat dissipation of the inner compartment body, ensuring the stable operation of the electronic compartment in a high temperature environment.

[0007] Preferably, a wiring port is provided at the top of the inner bin body, which is movable and penetrates to the outside of the outer bushing. One end of the wiring harness of the electronic instruments in the two electronic cavities is respectively penetrated into the cold storage cavity, and extends to the outside of the inner bin body through the corresponding wiring harness groove, extends upward along the axial direction of the outer wall of the inner bin body, and is connected to the wiring port. The wiring port facilitates the connection of the electronic instruments in the inner bin body with the external host and transmits relevant data. At the same time, the wiring port is movable and penetrates the outer bushing, so that it will not hinder the rotation of the outer bushing, so that it can still perform normal data transmission without affecting the rotation of the outer bushing.

[0008] As a further preferred embodiment, a wire harness tidying piece is provided above the inner part of the outer bushing, and the wire harness tidying piece is slidably sleeved on the outer part of the inner bin body, and a transmission mechanism is also provided between the wire harness tidying piece and the outer bushing, and the transmission mechanism is used to drive the wire harness tidying piece to reciprocate along the axial direction of the inner bin body when the outer bushing rotates with the rotary guide tool, so as to tidy and straighten the wire harness passing through the outer part of the inner bin body. In this way, the wire harness tidying piece can be dynamically tidyed after the wire harness tidying piece moves, ensuring that the wire harness remains neat when the rotary guide tool rotates, and avoiding mechanical damage caused by twisting and entanglement of the wire harness outside the inner bin body due to rotation, thereby increasing the service life of the wire harness and improving the reliability of the system.

[0009] Specifically, the wire harness organizing member includes a ring that is slidably sleeved on the outside of the inner warehouse body, and a plurality of wire harness clamps are arranged in an array outside the ring, each of the wire harness clamps includes a connecting piece connected to the ring, and an annular notch is provided in the middle of the connecting piece for the wire harness to pass through, and a plurality of organizing rollers are installed in the annular notch, and the outer peripheral surfaces of the plurality of organizing rollers are provided with an arc-shaped contour portion that matches the outer surface of the wire harness, and a raised brush strip is provided on the outside of the arc-shaped contour portion. Based on the above design, it is convenient for a plurality of wire harnesses that pass through the outside of the inner warehouse body to be organized by the wire harness clamp, which effectively solves the problem of the disorderly wire harnesses outside the inner warehouse body, and effectively avoids the wear and breakage of the wire harnesses, and the setting of the arc-shaped notch is conducive to its adaptation and fit with the outside of the wire harness, and the arc-shaped contour portion and the brush strip on the organizing roller help the organizing roller to roll up and down on the outer surface of the wire harness to organize, and can also scrape and clean the surface of the wire harness to avoid dust adhering to the surface of the wire harness, thereby further improving the heat dissipation performance of the wire harness.

[0010] Further preferably, a plurality of cooling guards are arranged inside the annular notch and are distributed at staggered intervals with the tidying rollers. The surfaces of the plurality of cooling guards on one side close to the wire harness are arc-shaped, and the interiors of the plurality of cooling guards are provided with cold pipes that are circulated and connected to the cold medium storage through flexible pipes. The cooling guards provided above facilitate the wire harness tidying piece to cool and dissipate heat from the outside of the wire harness through the cold pipes in the cooling guards when it moves up and down to tidy up the wire harness outside the inner warehouse body, thereby ensuring that the wire harness outside the inner warehouse body can also always maintain a stable and appropriate temperature for data transmission, avoiding overheating and causing aging of the wire harness, thereby further improving the overall reliability and durability of the electronic warehouse structure.

[0011] Specifically, the transmission mechanism includes a corrugated groove, a slider and a connecting rod connected to the slider at one end. The corrugated groove is formed on the inner wall of the outer bushing and surrounds the inner bin body. The slider is slidably arranged in the corrugated groove and connected to the collar through the connecting rod on one side thereof. Based on the above structure, when the outer bushing rotates, the wire harness organizer is driven to move up and down along the outer side of the inner bin body.

[0012] More specifically, an air cylinder is provided on the outside of the inner warehouse body and at a position corresponding to the refrigerant medium storage device. The length direction of the air cylinder extends along the axial direction of the inner warehouse body and is connected to the inner warehouse body through a support rod, and the outer side of the air cylinder is rotatably connected to the outer bushing through a connecting roller. A sealing piston plate is provided on the upper part of the interior of the air cylinder and at a position corresponding to the slider. A push rod penetrating to the outside of the air cylinder is provided on the upper part of the sealing piston plate, and a telescopic airbag is connected to the lower part of the sealing piston plate. The top end of the push rod is connected to the slider, and the interior of the telescopic airbag is filled with gas. An air supply pipe with one end penetrating the air cylinder and the inner warehouse body in sequence and extending to the inside of the refrigerant medium storage device is provided on the side of the telescopic airbag, and an expansion balloon is connected to the end of the air supply pipe away from the telescopic airbag. The above scheme promotes and enhances the circulation fluidity of the refrigerant in the refrigerant storage tank by arranging an air cylinder outside the inner compartment body and configuring a sealing piston plate and a telescopic air bag inside the air cylinder, thereby facilitating the high-speed flow of the refrigerant in the fluid channel and the cold pipe in the cooling guard plate, thereby realizing rapid absorption and transfer of heat in the electronic compartment, thereby significantly improving the cooling efficiency of the electronic compartment and ensuring that the electronic components can be maintained within a suitable operating temperature range in a high-temperature environment.

[0013] Furthermore, a bending guide is provided on the outer periphery of the cold medium storage device and between the two wiring harness grooves. The upper and lower parts of the bending guide are respectively provided with bending tubes that extend to the outside of the inner compartment body. The bending tube at the upper part of the bending guide is used to bend the wiring harness of the electronic instrument in the electronic cavity at the upper part of the cold storage cavity so that it extends upward after passing through the inner compartment body, and the bending tube at the lower part of the bending guide is used to bend the wiring harness of the electronic instrument in the electronic cavity at the lower part of the cold storage cavity so that it also extends upward after passing through the inner compartment body. Through the bending guide and bending tube designed as above, the wiring harness of the electronic instrument in the upper and lower electronic cavities of the cold storage cavity can be bent in an orderly manner through the corresponding bending tubes, ensuring that the wiring harness can extend upward after passing through the inner compartment body, thereby reducing the clutter and damage risk of the wiring harness.

[0014] As a preferred technical solution, a protective mechanism for supporting and protecting the inner warehouse body is also provided at the lower part of the inner part of the outer bushing, and the protective mechanism includes a protective sleeve, and the protective sleeve is fixedly clamped on the outside of the inner warehouse body, and a rotating sleeve is also sleeved on the outside of the protective sleeve, and a plurality of buffer hydraulic rods are hinged between the outside of the rotating sleeve and the inside of the outer bushing, and the tangent direction of any of the buffer hydraulic rods and the outer surface of the protective sleeve at the hinged position forms an acute angle with the length direction of the buffer hydraulic rod, and an annular gap is formed between the rotating sleeve and the protective sleeve, and a plurality of stabilizing rotating parts distributed in a circular array are embedded in the annular gap. Based on the above structure, it is convenient to provide stable support and protection for the inner warehouse body while the outer bushing rotates.

[0015] More specifically, any of the stabilizing rotating parts includes two magnetic parts that are arranged in an annular gap corresponding to each other and have the same magnetic poles and repel each other. A ball is embedded between the two magnetic parts, and an arc-shaped notch that fits the outer surface of the ball is opened on the side of the two magnetic parts close to the ball. The structure of the stabilizing rotating part can ensure that the rotating sleeve and the protective sleeve are always in coaxial rotation during rotation, thereby effectively reducing the rotation wear of the rotating sleeve. At the same time, it provides stable rotation support for the rotating sleeve, so that it can provide corresponding feedback support to the outer sleeve to ensure that the outer sleeve rotates more smoothly.

The present invention divides the electronic bin into an outer sleeve and an inner bin body, and the inner bin body and the outer sleeve are rotatably connected.

The present invention further provides a plurality of harness grooves arranged around the outer periphery of the cold medium storage device above and below the outer periphery, so that the harness axes of the electronic components in the two electronic cavities can be arranged so that they pass through the harness grooves in sequence, thereby avoiding intertwining of the harnesses, thereby achieving the arrangement of the harnesses inside the electronic compartment, ensuring that the internal space of the electronic compartment is reasonable and conducive to heat dissipation. At the same time, when the harness passes through the harness groove, since it is in direct contact with the outside of the cold medium storage device, the cold medium storage device can also dissipate heat and cool the harness, thereby further achieving efficient heat dissipation of the inner compartment body, ensuring the stable operation of the electronic compartment in a high temperature environment; 4.

[0023] The cooling medium in this embodiment mainly functions to absorb the heat in the electronic compartment through its circulation, so its types are various and this scheme is not particularly limited here. During the specific implementation, the operator can choose a cooling medium with good fluidity (such as water, mineral oil, silicone oil and industrial refrigerant, etc.) according to their own needs.

[0024] Embodiment 1;

[0025] This embodiment proposes an improvement measure for the electronic bin structure, that is, the electronic bin is divided into an outer bushing 1 and an inner bin body 2, and the inner bin body 2 and the outer bushing 1 are rotationally connected. When the outer bushing 1 rotates with the rotary guide tool, the electronic bin inside it does not rotate accordingly, so that the inner bin body 2 remains in a stationary state when the external rotary guide tool rotates, thereby providing a stable working environment for the internal electronic components, reducing the vibration and stress caused by rotation, thereby improving the service life and reliability of the electronic components, thereby ensuring the stable operation of the electronic bin in the rotary guide tool. Specifically; like Figures 1 to 8 As shown, an electronic bin structure for a rotary guide tool in a high temperature environment comprises an outer bushing 1 connected to the rotary guide tool on the outside, an inner bin body 2 is rotatably connected inside the outer bushing 1, a cold storage cavity is arranged in the middle of the inner bin body 2, electronic cavities 20 are respectively arranged at the top and bottom of the cold storage cavity, a cold medium storage 21 is arranged in the cold storage cavity, both the top and the bottom of the cold medium storage 21 penetrate into the corresponding electronic cavity 20, and a plurality of harness grooves 2 arranged around the cold medium storage 21 are arranged above and below the outer periphery thereof 10, wherein the harness groove 210 located above the outer periphery of the cold medium storage 21 is used to arrange the wiring harness 201 of the electronic instrument in the electronic cavity 20 at the upper part of the cold storage cavity, and the harness groove 210 located below the outer periphery of the cold medium storage is used to arrange the wiring harness 201 of the electronic instrument in the electronic cavity 20 at the lower part of the cold storage cavity; for the harness groove 210 at the outer periphery of the cold medium storage 21, it is preferably composed of a plurality of fins 2100 arranged in a circular array at the outer periphery of the cold medium storage 21, that is, in Figure 3 and Figure 4 As shown in the figure, among the multiple fins 2100, the gap formed between any two adjacent fins 2100 serves as the harness slot 210, and the side surfaces corresponding to any two adjacent fins 2100 form an inwardly concave arc surface, through which the harness 201 passing through the harness slot 210 can be clamped, and the multiple fins 2100 help to increase the thermal contact area of ​​the cold medium storage 21, thereby facilitating the enhancement of its heat exchange efficiency, so as to absorb part of the heat conducted from the two electronic cavities 20; The inner walls of the two electronic cavities 20 are provided with fluid channels 200 surrounding the electronic cavities 20, and the fluid channels 200 are connected to the cold medium storage 21 through the medium circulation pipe 211. The medium circulation pipe 211 is used to transport the cooling medium in the cold medium storage 21 to the fluid channels 200 on the inner walls of the two electronic cavities 20, so as to cool and dissipate the heat inside the two electronic cavities 20. The fluid channels 200 are preferably spirally surrounding the inner walls of the two electronic cavities 20.

[0026] Based on the above embodiments, please refer to Figure 1 and Figure 2 In this embodiment, a cold storage chamber is further provided in the middle of the inner chamber body 2, and a cold medium storage 21 is provided in the cold storage chamber, and electronic chambers 20 are respectively provided at the upper part and the bottom part of the cold storage chamber. Thus, by providing the two electronic chambers 20 close to the cold storage chamber, the cold medium storage 21 can provide a cold source for the two electronic chambers 20, and the heat in the two electronic chambers 20 can be quickly transferred to the cold storage chamber, so that the cold medium storage 21 can absorb the heat. At the same time, fluid channels 200 are provided on the inner walls of the two electronic chambers 20, and the fluid channels 20 0 is connected to the cold medium storage 21 through the medium circulation pipe 211, so that the cold medium in the cold medium storage 21 enters the fluid channel 200 through the medium circulation pipe 211 for circulation, so that the heat generated by the electronic components in the electronic cavity 20 is quickly absorbed by the circulation of the cold medium, thereby realizing active cooling and heat dissipation of the electronic cavity 20, realizing direct and efficient cooling of the electronic components, ensuring that the electronic components in the electronic cavity 20 are always maintained within a relatively constant and safe operating temperature range, and ensuring their stable operation. At the same time, in the specific implementation, through the circulation of the cold medium in the fluid channel 200, a thermal barrier layer is formed between the inner walls of the electronic cavity 20, which effectively isolates the external high temperature and heat from being conducted into the electronic cavity 20 while realizing the dissipation and absorption of the heat inside the electronic cavity 20, resulting in the restriction of the operation of its internal components; It should be further explained that in this embodiment, a plurality of harness grooves 210 are provided around the outer periphery of the cold medium storage 21, both above and below the outer periphery. Figure 3 and Figure 4By setting the harness groove 210, it is convenient to organize the axes of the harnesses 201 of the electronic components in the two electronic cavities 20, so that they pass through the harness groove 210 in sequence, thereby avoiding the intertwining of the harnesses 201, thereby realizing the organization of the harnesses 201 inside the electronic compartment, ensuring that the internal space of the electronic cavity 20 is reasonable, which is conducive to heat dissipation. At the same time, when the harness 201 passes through the harness groove 210, since it is in direct contact with the outside of the cold medium storage 21, the cold medium storage 21 can also dissipate heat and cool the harness 201, thereby further realizing efficient heat dissipation of the inner compartment body 2, ensuring the stable operation of the electronic compartment in a high temperature environment.

[0027] Based on the above embodiment, as a preferred implementation mode, a wiring port 22 is provided at the top of the inner chamber body 2 and is movable through to the outside of the outer sleeve 1. Figure 1 As shown in the figure, one end of the harness 201 of the electronic instruments in the two electronic cavities 20 respectively penetrates into the cold storage cavity, passes through the corresponding harness slot 210 and extends to the outside of the inner warehouse body 2, extends upward along the axial direction of the outer wall of the inner warehouse body 2 and is connected to the wiring port 22. The wiring port 22 facilitates the connection of the electronic instruments in the inner warehouse body 2 with the external host and transmits relevant data. At the same time, the wiring port 22 movably penetrates the outer bushing 1, so that it will not hinder the rotation of the outer bushing 1, so that it can still perform normal data transmission without affecting the rotation of the outer bushing 1.

[0028] Based on the above embodiment, in order to ensure that the wire harness 201 of the electronic instrument passing through the outside of the inner compartment body 2 is arranged, and the wire harness 201 between the inner compartment body 2 and the outer liner 1 can also be effectively arranged, this embodiment further provides a wire harness arrangement member 23 above the inner part of the outer liner 1, such as Figure 2 As shown, the harness tidying member 23 is slidably sleeved on the outside of the inner warehouse body 2, and a transmission mechanism 24 is also provided between the harness tidying member 23 and the outer bushing 1. The transmission mechanism 24 is used to drive the harness tidying member 23 to move back and forth along the axial direction of the inner warehouse body 2 when the outer bushing 1 rotates with the rotary guide tool, so as to tidy and straighten the harness 201 that is arranged outside the inner warehouse body 2. Through the above embodiment, when the rotary guide tool rotates, the outer bushing 1 can rotate accordingly, so that after the outer bushing 1 rotates, the harness tidying member 23 is driven to move back and forth along the axial direction of the inner warehouse body 2 through the transmission mechanism 24, so that after the harness tidying member 23 moves, the harness 201 is dynamically arranged, ensuring that the harness 201 remains neat when the rotary guide tool rotates, avoiding the harness 201 located outside the inner warehouse body 2 from being twisted and twisted due to rotation and causing mechanical damage, thereby increasing the service life of the harness 201 and improving the reliability of the system.

[0029] Based on the wire harness organizer 23 of the above embodiment, a preferred implementation method thereof is described here. Figure 5 and Figure 6 The wire harness organizing member 23 includes a ring 230 slidably mounted on the outside of the inner compartment body 2, and a plurality of wire harness clamps 231 are arranged in an array outside the ring 230, each of the wire harness clamps 231 includes a connecting piece 2310 connected to the ring 230, and an annular notch for the wire harness 201 to pass through is provided in the middle of the connecting piece 2310, and a plurality of organizing rollers 2311 are installed in the annular notch, and an arc-shaped contour portion adapted to the outer surface of the wire harness 201 is provided on the outer circumference of the plurality of organizing rollers 2311, and a raised brush strip is provided on the outside of the arc-shaped contour portion.

[0030] It should be noted here that the wire harness clamping member 231 of the present embodiment can perform corresponding clamping and arranging of multiple wire harnesses 201 that are passed through the outside of the inner bin body 2, effectively solving the problem of the disorderly wire harnesses 201 outside the inner bin body 2, and through the setting of the arc-shaped notch, it is convenient for it to adapt and fit with the outside of the wire harness 201. At the same time, through the arc-shaped contour portion and the brush strip on the arranging roller 2311, the arranging roller 2311 can also roll up and down on the outer surface of the wire harness 201 to tidy up the surface, and at the same time, the surface of the wire harness 201 can be scraped and cleaned to prevent dust from adhering to the surface of the wire harness 201, thereby further improving the heat dissipation performance of the wire harness 201.

[0031] In addition, it should be noted that in a high temperature environment, due to the limited internal space of the electronic compartment, the distribution of the wiring harness 201 is often dense. Therefore, when it is in use, the wiring harness 201 itself will also generate corresponding heat accumulation as a large amount of data is transmitted. Therefore, in order to ensure that the wiring harness 201 works at an appropriate temperature and prevent the risk of aging and failure of the wiring harness 201 due to overheating, the present embodiment further preferably provides a plurality of cooling guard plates 2312 that are staggered and spaced apart from the sorting rollers 2311 inside the annular notch, such as Figure 7As shown, the surfaces of one side of the plurality of cooling guards 2312 close to the wiring harness 201 are arc-shaped, and the interior of the plurality of cooling guards 2312 is provided with a cold pipe 23120 that is circulated and connected to the cold medium storage 21 through the flexible pipe 212, so as to ensure that the wiring harness 201 outside the inner warehouse body 2 can always be kept at a stable and appropriate temperature for data transmission, and avoid overheating and aging of the wiring harness 201, so as to further improve the overall reliability and durability of the electronic warehouse structure. It should be added that as a flexible pipe 212, it generally has strong elasticity and ductility. Therefore, the purpose of using the flexible pipe 212 in this embodiment is to utilize its good elasticity and ductility to enable it to normally transport the cooling medium to the cold pipe 23120 in the cooling guard 2312 without affecting the axial movement of the cooling guard 2312 with the wiring harness clamp 231, so as to ensure that the cooling guard 2312 and the cold pipe 23120 normally dissipate heat and cool the wiring harness 201 during the movement.

[0032] Based on the above embodiment, in order to facilitate the outer sleeve 1 to drive the harness arrangement member 23 to move up and down along the outside of the inner bin body 2 when rotating, the transmission mechanism 24 is specifically described here. Figure 6 and Figure 8 As shown, the transmission mechanism 24 includes a corrugated groove 240, a slider 241 and a connecting rod 242 connected to the slider 241 at one end. The corrugated groove 240 is provided on the inner wall of the outer bushing 1 and surrounds the inner chamber 2. The slider 241 is slidably arranged in the corrugated groove 240 and connected to the collar 230 through the connecting rod 242 located on one side thereof. It should be understood that when the outer bushing 1 rotates, the corrugated groove 240 on its inner wall will also rotate accordingly. When the corrugated groove 240 rotates, the position of the slider 241 in the corrugated groove 240 can change in real time, that is, it will move from the trough position of the corrugated groove 240 to the peak position of the corrugated groove 240 within a period of time. Therefore, by changing the position of the slider 241 (that is, the peak and the trough), the collar 230 can be driven to slide up and down, thereby driving the wire harness organizer 23 to move back and forth up and down along the axial direction of the inner chamber 2. Based on the transmission mechanism 24 disclosed above, it is necessary to further explain that, in order to facilitate the axial sliding of the ring 230 on the outside of the inner chamber body 2, the present embodiment provides a plurality of guide grooves on the outer periphery of the inner chamber body 2 along its axial direction, and a guide block connected to the inner surface of the ring 230 is slidably embedded in the guide groove. Through the limiting and guiding effect of the guide groove and the guide block, the ring 230 can always perform axial reciprocating sliding under the drive of the transmission mechanism 24, that is, to prevent the ring 230 from rotating in the same direction as the outer sleeve 1 and making it unable to move up and down.

[0033] Based on the above embodiment, in order to facilitate the wire harness 201 of the electronic instrument in the upper and lower electronic cavities 20 of the cold storage cavity to extend upward after passing through the inner compartment body 2 to avoid bending and breaking, the present embodiment further provides a bending guide 250 at the outer periphery of the cold medium storage 21 and between the two wire harness grooves 210. Figure 2 As shown in the figure, the upper and lower parts of the bending guide 250 are respectively provided with bending tubes 251 which penetrate to the outside of the inner compartment body 2. The bending tube 251 at the upper part of the bending guide 250 is used to bend the wiring harness 201 of the electronic instrument in the electronic cavity 20 at the upper part of the cold storage cavity so that it can extend upward after passing through the inner compartment body 2, and the bending tube 251 at the lower part of the bending guide 250 is used to bend the wiring harness 201 of the electronic instrument in the electronic cavity 20 at the lower part of the cold storage cavity so that it can also extend upward after passing through the inner compartment body 2, so that the wiring harness 201 of the electronic instrument in the upper and lower electronic cavities 20 of the cold storage cavity can be bent in an orderly manner through the corresponding bending tubes 251, thereby reducing the risk of disorder and breakage of the wiring harness 201.

[0034] Based on the above embodiment, as a preferred implementation method, in order to provide stable support and protection for the inner chamber body 2 while the outer sleeve 1 rotates, a protection mechanism 26 for supporting and protecting the inner chamber body 2 is further provided at the lower part of the outer sleeve 1. Fig.10 As shown, the protective mechanism 26 includes a protective sleeve 260, and the protective sleeve 260 is fixedly clamped on the outside of the inner chamber body 2. A rotating sleeve 261 is also sleeved on the outside of the protective sleeve 260. A plurality of buffer hydraulic rods 262 are hinged between the outside of the rotating sleeve 261 and the inside of the outer sleeve 1, and the tangent direction of the hinged position between any of the buffer hydraulic rods 262 and the outer surface of the protective sleeve 260 is at an acute angle to the length direction of the buffer hydraulic rod 262. An annular gap is formed between the rotating sleeve 261 and the protective sleeve 260, and a plurality of stabilizing rotating parts distributed in a circular array are embedded in the annular gap.

[0035] Specifically, the protective structure disclosed in this embodiment includes a protective sleeve 260, a rotating sleeve 261 and a buffering pressure rod 262. Since the rotating sleeve 261 is fixedly clamped on the outside of the inner chamber body 2, and the protective sleeve 260 is located on the outside of the rotating sleeve 261, and a plurality of stabilizing rotating parts are provided in the annular gap between the two, the protective sleeve 260 and the rotating sleeve 261 are rotatably connected, and the outer periphery of the protective sleeve 260 is hinged to the outer bushing 1 through a plurality of inclined buffering pressure rods 262, so when the vibration impact of the rotary guide tool is transmitted to the outer bushing When the protective sleeve 26 is installed, the impact force will be guided and dispersed along the inclined direction of the buffer pressure rod 262, and at the moment when the buffer pressure rod 262 is impacted, it can also rotate within a certain angle range due to its own hinge, so as to further disperse the vibration impact force, and when it is impacted, the inclined buffer pressure rod 262 can complete its buffering action through a longer path when absorbing the impact force (equivalent to increasing the buffering distance), so that the impact force has more time and space to be absorbed and slowed down, so as to enhance the support and protection performance of the protective mechanism 26. By setting the stabilizing rotating part, the rotation support between the rotating sleeve 261 and the protective sleeve 260 is realized, avoiding physical contact between them, reducing wear and maintenance requirements, and making the rotating sleeve 261 more stable when rotating, and then performing a certain rotation support feedback on the external bushing 1, so that it can still maintain stable rotation when rotating with the rotary guide tool, avoiding damage to the inner chamber body 2.

[0036] Furthermore, any of the stabilizing rotating parts includes two magnetic parts 2600 which are arranged in an annular gap corresponding to each other and have the same magnetic poles and repel each other. A ball 2601 is embedded between the two magnetic parts 2600, and an arc-shaped notch which fits the outer surface of the ball 2601 is also provided on the side of the two magnetic parts 2600 close to the ball 2601. The structure of the stabilizing rotating part can ensure that the rotating sleeve 261 and the protective sleeve 260 are always in coaxial rotation during rotation, thereby effectively reducing the rotation wear of the rotating sleeve 261. At the same time, it provides stable rotation support for the rotating sleeve 261, so that it can provide corresponding feedback support to the outer bushing 1 to ensure that the outer bushing 1 rotates more smoothly.

[0037] Embodiment 2;

[0038] It should be noted that in order to further enhance the rapid absorption of heat in the electronic warehouse and ensure that the temperature in the electronic warehouse is always balanced, this solution requires that the cold medium in the cold medium storage 21 can continue to circulate, and the conventional circulation is often achieved by adding relevant medium circulation pumps, but this method is not applicable to the electronic warehouse structure of this application, because the space in the electronic warehouse itself is limited. If a corresponding medium circulation pump is added, it will take up additional space. At the same time, the medium circulation pump will also generate corresponding heat when working, which will increase the heat source in the electronic warehouse. In view of this, this embodiment proposes a more preferred implementation method based on the above embodiment, which realizes that without adding relevant medium circulation pumps, the circulation flow of the cold medium in the cold medium storage 21 is promoted and strengthened through mutual cooperation with the transmission mechanism 24, as follows: like Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that an air cylinder 270 is further provided outside the inner warehouse body 2 and at a position corresponding to the refrigerant medium storage 21. The length direction of the air cylinder 270 extends along the axial direction of the inner warehouse body 2 and is connected to the inner warehouse body 2 through a support rod. The outer side of the air cylinder 270 is rotatably connected to the outer bushing 1 through a connecting roller. A sealing piston plate 271 is further provided at the upper part of the inner part of the air cylinder 270 corresponding to the position of the slider 241. The upper part of the sealing piston plate 271 is A push rod 272 is provided which penetrates to the outside of the gas cylinder 270, and a telescopic air bag 273 is connected to the lower part of the sealing piston plate 271. The top end of the push rod 272 is connected to the slider 241, and the inside of the telescopic air bag 273 is filled with gas. An air pipe 274 is provided on the side of the telescopic air bag 273, one end of which penetrates the gas cylinder 270 and the inner chamber 2 in sequence and extends to the inside of the cold medium storage 21. An expansion balloon 275 is connected to the end of the air pipe 274 away from the telescopic air bag 273.

[0039] This embodiment promotes and enhances the circulation fluidity of the refrigerant in the refrigerant storage 21 by setting an air cylinder 270 outside the inner compartment body 2 and configuring a sealing piston plate 271 and a telescopic air bag 273 inside the air cylinder 270, thereby facilitating the high-speed flow of the refrigerant in the fluid channel 200 and the cold pipe 23120 in the cooling guard plate 2312, thereby achieving rapid absorption and transfer of heat in the electronic compartment, thereby significantly improving the cooling efficiency of the electronic compartment and ensuring that the electronic components can be maintained within a suitable operating temperature range in a high-temperature environment. Specifically, when the slider 241 of the transmission mechanism 24 slides up and down through the corrugated groove 240, the sealing piston plate 271 can be pushed to move up and down in the air cylinder 270, so that after the sealing piston plate 271 moves up and down, it pushes the telescopic airbag 273 to reciprocate and contract, and then the telescopic airbag 273 can push the gas inside it to the expansion balloon 275 after reciprocating contraction, so that the expansion airbag can be expanded and deformed periodically, so that after the expansion cavity is expanded and deformed, the refrigerant in the refrigerant storage 21 can be squeezed, thereby promoting its active circulation flow in the refrigerant storage 21 and the fluid channel 200 and the cold pipe 23120, thereby further improving the absorption and heat dissipation efficiency. Compared with the prior art, this solution cleverly combines the functions of the air cylinder 270 and the refrigerant storage 21, realizes the active circulation of the refrigerant through the expansion and contraction of the gas, and overcomes the limitations of the traditional passive heat dissipation method. It not only improves the heat dissipation performance of the electronic warehouse, but also enhances the overall reliability and adaptability of the system, especially in application scenarios in high temperature environments, and has significant technical advantages.
