[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] See also Figures 1 to 15 As shown, an embodiment of the portable substation data communication device provided by the present invention.

[0023] Portable substation data communication equipment includes: Shell 1; A data communication module (not shown in the figure) is installed inside the housing 1 and is used to collect operating data of the substation; The current transmission module 3 includes a power cord 31 and a plug 32. The power cord 31 passes through the housing 1 and is flexibly connected to the housing 1. One end of the power cord 31 extends into the housing 1 to connect to the data communication module, and the other end of the power cord 31 extends outside the housing 1 to connect to the plug 32. The plug 32 is used to connect to an external power source. A power cord positioning mechanism 4 is installed outside the housing 1 and is used to clamp the portion of the power cord 31 extending outside the housing 1; A lifting mechanism 5 is swingably and telescopically mounted on the outside of the housing 1 for staff to lift; An external mounting mechanism 6 is mounted on the outside of the housing 1 in an adjustable manner and is used to be connected and fixed to its mounting base; A data line interface mechanism 7, mounted on the outside of the housing 1, for elastically clamping the substation data line passing through the housing 1; A display screen 8 is mounted on the housing 1 and connected to the data communication module for displaying substation operation data; The indicator light 9 is installed on the housing 1 and is used for safety warning.

[0024] In the above description, housing 1 refers to the protective structure that supports various functional components. Its internal space division must meet modular installation requirements, providing equipment protection and component positioning. The data communication module refers to the substation operation data acquisition unit, responsible for data conversion and transmission. The flexible connection of the current transmission module 3 ensures that the power cord 31, when passing through housing 1, maintains power continuity while preventing bending damage. The power cord positioning mechanism 4 is a wire securing device that prevents wires from becoming disorganized during transportation. The lifting mechanism 5 is a deformable carrying component that uses a hinged and sliding structure to transform between storage and use, saving space and making it easy to hold. The external mounting mechanism 6 is an angle-adjustable fixture that adapts to different mounting surfaces. The data cable interface mechanism 7 is an elastic locking device that secures the data cable via a spring-loaded contact plate, ensuring a reliable cable connection. The display screen 8 is a data visualization terminal that provides real-time feedback on substation operating parameters. The indicator light 9 is a safety warning device that indicates device status through different flashing patterns.

[0025] Through the above-mentioned technical solutions, this invention effectively resolves the technical bottleneck of limited equipment installation locations, adapting to different spatial layout requirements through an angle-adjustable mounting mechanism. The power cord clamp assembly significantly improves cable management efficiency and reduces the risk of failures caused by cable entanglement. The deformable lifting mechanism enhances carrying comfort and adapts to handling operations in confined spaces. The elastic clamping structure ensures stable data cable connections and prevents signal transmission interruptions. The integrated display and warning system enables real-time monitoring of equipment status, enhancing operational safety.

[0026] In this embodiment, the power line 31 is connected to the housing 1 through a silicone sleeve 33 . The silicone sleeve 33 is fixed in a wire hole of the housing 1 , and the power line 31 passes through the silicone sleeve 33 .

[0027] In the above, the silicone sleeve 33 refers to a sleeve structure made of a flexible silicone material. Specifically, it can be fixed in the wire hole of the housing 1 by interference fit or bonding, providing a sealing and cushioning effect. The wire hole refers to a through-hole provided in the housing 1 for passing the power cord 31. Specifically, it can be a hole structure with a diameter slightly smaller than the outer diameter of the silicone sleeve 33, and the silicone sleeve 33 is fixed by interference fit. The power cord 31 passing through the silicone sleeve 33 means that the power cord 31 passes through the inside of the silicone sleeve 33. The inner diameter of the silicone sleeve 33 can match the outer diameter of the power cord 31, and the elasticity of the silicone sleeve 33 can be used to form a natural clamp.

[0028] Specifically, the elastic properties of the silicone sleeve 33 cause it to deform when subjected to pressure. When the power cord 31 is bent by external forces, the silicone sleeve 33 adapts to the bending angle of the cord, preventing bending stress concentration caused by a rigid connection. The interference fit between the silicone sleeve 33 and the cable hole creates a sealed interface, effectively preventing external dust or liquid from entering the interior of the housing 1. This structure adapts to the frequent bending of the power cord 31 during the movement of substation communication equipment, while also preventing wear and tear at the connection between the power cord 31 and the housing 1 caused by repeated bending.

[0029] Through the above-described technical solution, the present invention achieves a flexible, sealed connection between the power cord 31 and the housing 1, resolving the problems of difficult bending, easy wear, and insufficient sealing caused by rigid connections. The power cord 31 can be bent and adjusted at multiple angles under the action of external forces while maintaining a sealed connection. The adaptive deformation characteristics of the silicone sleeve effectively disperse bending stress and extend the service life of the power cord. This structure simplifies installation and maintenance operations. In scenarios where substation communication equipment is frequently moved, the direction of the power cord 31 can be quickly adjusted without compromising the sealing performance.

[0030] In this embodiment, the power line positioning mechanism 4 includes: The support base 41 is connected to the housing 1 through a connecting plate 42 at the bottom and has a groove 43 at the top for embedding and supporting the power cord 31; A first U-shaped plate 44 includes a main portion and two bent portions bent toward the same side relative to the main portion. The main portion of the first U-shaped plate 44 is connected to and fixed to the support seat 41 and is located on one side of the notch of the groove 43. A first rotating shaft 45 is connected between the two bent portions of the first U-shaped plate 44. An arc-shaped pressing plate 46 , the concave side of which is used to press the power cord 31 into the groove 43 . The arc-shaped pressing plate 46 has a first buckle plate portion 47 and a second buckle plate portion 48 on both sides along the arc length direction, respectively. The first buckle plate portion 47 is connected to the first rotating shaft 45 . The second U-shaped plate 49 includes a main body and two bent parts bent to the same side relative to the main body. The main body of the second U-shaped plate 49 is connected to and fixed to the support seat 41 and is located on the other side of the notch of the groove 43. The main body of the second U-shaped plate 49 is connected to a first spring member 410, and the first spring member 410 is connected to an abutment piece 411. The second buckle plate 48 is pressed on the abutment piece 411. The bent part of the second U-shaped plate 49 is connected to an L-shaped plate 412. The L-shaped The plate member 412 includes a first plate portion and a second plate portion at an angle to each other, the first plate portion is connected to the bent portion of the second U-shaped plate member 49, and a pressure rod 413 is connected to the second plate portion, one end of the pressure rod 413 passes through the bent portion of the second U-shaped plate member 49 to press the second buckle plate portion 48 onto the abutment piece 411, and the other end of the pressure rod 413 is connected to a first magnetic plate 414, which is used to attract the second plate portion, and a pull ring 415 is connected to the first magnetic plate 414.

[0031] In the above description, support base 41 refers to the base component that supports power cord 31. The cross-sectional shape of the groove 43 on its top is adapted to the outer diameter of power cord 31, which is used to limit the lateral displacement of power cord 31. First U-shaped plate 44 is a fixed bracket with a curved structure, which provides a rotation fulcrum for the curved pressure plate through the first rotating shaft 45. Curved pressure plate 46 is a clamping component with a curved surface structure. The radius of its concave curvature matches the outer diameter of power cord 31, which evenly distributes pressure during the clamping process. The thickness of the first and second gusset portions 47, 48 is less than that of the arc-shaped pressure plate 46. The second U-shaped plate 49 is a fixed bracket with a bent structure. The abutment piece 411 is elastically connected to the second U-shaped plate 49. The L-shaped plate 412 is a fixed bracket with a bent structure. The pressure rod 413 is a rigid element for transmitting pressure. One end of the pressure rod 413 presses the second gusset portion 48 onto the abutment piece 411. The abutment piece 411 and the pressure rod 413 elastically clamp the second gusset portion 48. The other end of the pressure rod 413 is maintained in a position pressing the second gusset portion 48 by the magnetic force of the first magnetic plate 414. The pull ring 415 is an operating component for releasing the magnetic lock, which drives the first magnetic plate 414 out of the contact surface by pulling it outward.

[0032] Specifically, after the power cord 31 is inserted into the groove 43 of the support base 41, the operator presses down the arc-shaped pressure plate 46 to rotate it around the first rotating shaft 45. The second buckle plate portion 48 squeezes the abutment piece 411 to compress the first spring member 410 to store energy. When the arc-shaped pressure plate 46 reaches the predetermined clamping position, the pressure rod 413 adsorbs and fixes the second plate portion of the L-shaped plate 412 through the first magnetic plate 414. At this time, the spring force and the magnetic force jointly maintain the clamping state. In the unlocked state, the pull ring 415 is pulled outward to release the magnetic plate from adsorption. The pressure rod 413 releases the second buckle plate portion 48, and the second buckle plate portion 48 further releases the abutment piece 411. The abutment piece 411 restores its shape and position under the action of the spring force.

[0033] Through the above-mentioned technical solution, the present invention effectively solves the problem of loosening of the power cord 31 due to shaking during transportation. Its elastic clamping structure can absorb the vibration energy generated by the equipment during movement. Actual measurements show that the cable displacement is less than 1mm in a vibration environment with a frequency of 10Hz to 50Hz. The clamping mechanism unlocking process does not require the assistance of tools, and the single-person operation time is controlled within 2 seconds, significantly improving the efficiency of equipment carrying and deployment. The mechanism can be repeated more than 10,000 times, and the clamping force attenuation rate is less than 5%, meeting the reliability requirements of long-term field operation of substation communication equipment.

[0034] In this embodiment, the pulling mechanism 5 includes: Two rocker arms 51, one end of which is rotatably connected to the housing 1 via a second rotating shaft 52, and the other end of which is provided with a slide groove 53, and a locking block 54 is provided on one side of the notch of the slide groove 53; The first U-shaped rod 55 includes a main body and a bent portion bent toward the same side of the main body. The bent portion of the first U-shaped rod 55 is slidably connected to the slide grooves of the two rocker arms 51 via a first columnar member 56. One end of the first columnar member 56 is connected to a first end plate 57. A locking screw 58 and a limiting sleeve 59 are connected to the first end plate 57. One end of the locking screw 58 is connected to the first end plate 57, and the other end of the locking screw 58 is connected to the locking block 54. When the locking block 54 and the rocker arm 51 abut against each other, the limiting sleeve 59 is used to limit the position of the locking screw 58. The first end plate 57 is provided with a straight-shaped protrusion 510 for a worker to twist. The second U-shaped rod 511 includes a main body and a bent portion bent to the same side of the main body. The two bent portions of the second U-shaped rod 511 are connected to the main body of the first U-shaped rod 55. The main body of the second U-shaped rod 511 is used for staff to lift.

[0035] In the above, the rocker arm 51 is hinged to the housing 1 through the second rotating shaft 52, allowing the lifting mechanism to swing around the axis as a whole to adapt to different carrying angles. The slide 53 adopts a long slotted structure, so that the first columnar member 56 can slide along the slide 53 to adjust the lifting length. The locking block 54 is provided with a threaded hole, which cooperates with the locking screw 58 to achieve locking. The bent portion of the first U-shaped rod 55 is slidably connected to the slide 53, and the pulling force is transmitted through the first columnar member 56. The position is fixed by the friction force generated by tightening the locking block 54. The limiting sleeve 59 adopts a sleeve structure to constrain the axial displacement of the locking screw 58. The I-shaped protrusion 510 adopts a transverse rib design to facilitate manual force to rotate the locking screw 58. The second U-shaped rod 511 and the first U-shaped rod 55 form a double U-shaped gripping structure.

[0036] Specifically, when the rocker arm 51 swings around the second rotating shaft 52, it drives the first U-shaped rod 55 to change the pulling angle, while the first columnar member 56 slides in the slide groove 53 to adjust the pulling length. When the target position is reached, the locking screw is driven into the threaded hole of the locking block 54 by rotating the I-shaped protrusion 510, so that the end of the locking screw 58 is connected with the locking block 54 to generate friction, locking the rocker arm 51 and the first U-shaped rod 55. The limiting sleeve 59 limits the axial displacement of the locking screw 58 during the clamping process. The second U-shaped rod 511 disperses the pulling stress through the double U-shaped structure, and its bent portion is rigidly connected to the first U-shaped rod 55 to form a force fulcrum, avoiding single-point stress concentration.

[0037] Through the above technical solution, the present invention realizes that the pulling mechanism 5 can be swung upward 90 degrees to a vertical pulling state when carried, and can be folded down to fit the shell during transportation. The length adjustment function adapts to the gripping needs of people with different arm spans. For example, people with a height of 160-190 cm can lift it comfortably. The threaded locking structure ensures that there is no accidental contraction during the pulling process, and the double U-shaped rod disperses stress to increase the single pulling load capacity to 15 kg. To unlock, only the locking screw 58 needs to be rotated in the opposite direction to release the lock, and the operation time is shortened to less than 2 seconds.

[0038] In this embodiment, the external mounting mechanism 6 includes: A mounting plate 61, connected and fixed to the housing 1; A first adjusting arm 62, one end of which is hingedly connected to a fixing plate 63, and the fixing plate 63 is fixedly connected to the mounting plate 61; A second adjusting arm 64, one end of which is hingedly connected to the other end of the first adjusting arm 62, and a guide sleeve 65 is connected to the second adjusting arm 64; a linear drive device 66 mounted on the second adjustment arm 64; A third adjustment arm 67 , one end of which is connected to the telescopic shaft of the linear drive device 66 ; A guide rod 68 is connected to the third adjustment arm 67 via a fixing block 69 and is slidably connected to the guide sleeve 65; The second magnetic plate 610 is hingedly connected to the other end of the third adjustment arm 67 , and the second magnetic plate is used for attracting the installation base.

[0039] In the above, the mounting plate 61 refers to the basic component that supports the external mounting mechanism 6, and forms a stable support foundation by forming a rigid connection with the shell 1. The first adjusting arm 62 refers to the primary angle adjustment component, which can be specifically implemented by a hinge mechanism with a bearing, so that the mounting mechanism obtains the degree of freedom of rotation in the horizontal plane. The second adjusting arm 64 refers to the secondary angle adjustment component, which can be specifically implemented by a universal hinge structure, and cooperates with the first adjusting arm 62 to form a multi-directional angle adjustment capability. The guide sleeve 65 refers to a guide component that constrains the motion trajectory, and ensures the accuracy of linear motion through sliding cooperation with the guide rod 68. The linear drive device 66 refers to an actuator that provides linear power, and an electric push rod can be used to drive the third adjusting arm through the telescopic shaft to adjust the length. The second magnetic plate 610 refers to a quick fixing component, which achieves quick connection with the mounting base through magnetic attraction.

[0040] Specifically, the mounting plate 61 is rigidly connected to the shell 1 to form a stable support platform, and the fixed plate 63 serves as the mounting base of the first adjusting arm 62 to provide an initial rotation fulcrum. The first adjusting arm 62 realizes horizontal rotation adjustment through a hinge point, and the second adjusting arm 64 forms a second degree of rotation freedom in the vertical plane through a universal hinge. When the linear drive device 66 pushes the third adjusting arm 67 to extend or retract, the guide rod 68 slides along the guide sleeve 65 to limit the offset and ensure the linearity of the motion trajectory. The second magnetic plate 610 adapts to the surface angle of the mounting base through a hinge structure and completes rapid adsorption and fixation under the action of magnetic force. Through the combined rotation of the first adjusting arm 62 and the second adjusting arm 64, in conjunction with the telescopic stroke of the linear drive device 66, a multi-directional position adjustment capability in three-dimensional space is formed.

[0041] Through the above-mentioned technical solution, the present invention achieves multi-level adjustment capability for the installation angle in both the horizontal and vertical directions, adapting to the differences in planar angles of different installation bases. The combination of the linear drive device 66 and the guide mechanism enables precise length adjustment while maintaining stability. The magnetic fixing method significantly improves installation efficiency, eliminating the need for traditional fastening tools. The multi-level articulated structure enables spatial adaptability of the installation mechanism, effectively resolving the technical challenge of limited installation locations for substation communication equipment.

[0042] In this embodiment, two external mounting mechanisms 6 are provided.

[0043] In the above, two external mounting mechanisms 6 are provided to form symmetrically distributed fixed points, thereby improving the redundancy and anti-displacement capability of the data communication equipment installation.

[0044] Specifically, two external mounting mechanisms 6 are arranged on both sides of the housing 1, and each external mounting mechanism 6 includes an independently operable adjustment arm and a magnetic component. During installation, the angles of the two external mounting mechanisms 6 can be adjusted separately to adapt to the spatial limitations of different mounting surfaces. For example, when the mounting base has a concave or convex surface or an inclined surface, the two magnetic plates can be independently adjusted to different angles to match the contact surface. In the fixed state, the dual support points formed by the two external mounting mechanisms 6 can balance the gravity distribution of the equipment, avoiding connection failure caused by external force vibration during single-point connection.

[0045] Through the above technical solution, the present invention effectively solves the problem of insufficient installation stability of portable equipment in the complex environment of substations. The symmetrically distributed dual installation mechanisms form a complementary fixed structure, which not only ensures the stable connection of the equipment under tilting and vibration conditions, but also provides redundant adjustment space for different installation scenarios, preventing the risk of equipment falling off due to single point failure.

[0046] In this embodiment, the data line interface mechanism 7 includes: The interface part 71 is connected to the housing 1 and is provided with a through hole 72 for the substation data line to pass through. A second cylindrical member 73 is slidably connected to the interface member 71. One end of the second cylindrical member 73 extends into the through hole 72 and is connected to a contact plate 74. The contact plate 74 is provided with a convex tooth 75 for contacting the substation data line. The other end of the second cylindrical member 73 extends out of the through hole and is connected to a second end plate 76. A second spring member 77 is sleeved on the second cylindrical member 73 and is located between the second end plate 76 and the housing 1. An L-shaped rod 78 is connected to the second end plate 76. One end of the L-shaped rod 78 is connected to the second end plate 76, and the other end of the L-shaped rod 78 is connected to a third end plate 79. A V-shaped rod 710 is connected to the third end plate 79. The V-shaped rod 710 includes a first rod segment and a second rod segment that are angled with each other. The support rod 711 has one end connected to the housing 1 and the other end connected to a third rotating shaft 712 . The third rotating shaft 712 is connected to the corner position of the V-shaped rod 710 .

[0047] In the above description, the interface member 71 refers to the connecting component used to secure the substation data cable. The second cylindrical member 73 is a clamping component that slides radially along the through-hole 72, and its sliding displacement changes the contact pressure between the contact plate 74 and the substation data cable. The contact plate 74 is an engaging component that directly clamps the substation data cable. Specifically, it can be implemented as a rubber plate with serrated protrusions. The tooth tip angle of the protruding teeth can be set to an acute angle to enhance the engaging effect. The second spring member 77 is an energy storage element that provides elastic pressure. Specifically, it can be implemented as a helical compression spring. Its stiffness coefficient can be adjusted according to the diameter range of the data cable. The V-shaped rod 710 is an operating component that creates a lever action. Specifically, it can be implemented as a stamped steel plate bent part. The angle between the two rod segments can be set to 90 degrees to 150 degrees. The third rotating shaft 712 is a rotating fulcrum for achieving angle adjustment. Specifically, it can be implemented as a pin structure with a ball bearing, with its axis perpendicular to the extension direction of the support rod 711.

[0048] Specifically, when the substation data cable is inserted into through-hole 72, the second spring member 77 pushes the second cylindrical member 73, causing the contact plate 74 to press against the surface of the substation data cable. At this point, the protruding teeth 75 engage the cable sheath, generating a frictional force. To release the clamp, the free end of the second segment of the V-shaped rod 710 is pressed, causing the first segment to rotate about the third axis 712. This, in turn, pulls the second end plate through the L-shaped rod 78, compressing the second spring member 77 and separating the contact plate 74 from the substation data cable. The support rod 711 and the third axis 712 form the pivot point.

[0049] Through the above-mentioned technical solution, the present invention achieves reliable fixation of substation data cables in vibrating environments, avoiding damage to the cable surface caused by traditional rigid clamping. The operator can clamp and release the cables without tools. The convex teeth 75 of the contact plate 74 and the spring pressure automatically adjust the clamping force according to the cable diameter, ensuring effective fixation of thin cables while avoiding excessive compression of thicker cables.

[0050] In this embodiment, the power cord positioning mechanism 4 and the display screen 8 are mounted on the top surface of the housing 1; The current transmission module 3, the external mounting mechanism 6, the data line interface mechanism 7 and the indicator light 9 are mounted on the side surface of the housing 1; The lifting mechanism 5 is connected to the side surface of the housing 1 and can be swung to the bottom and top surfaces of the housing 1 .

[0051] In the above, the bottom surface of the shell 1 refers to the surface facing the installation base, the top surface of the shell 1 refers to the surface facing away from the installation base, and the side surface of the shell 1 refers to the surface connecting the bottom surface and the top surface of the shell 1. The power cord positioning mechanism 4 is arranged on the top surface to keep the power cord 31 away from the operating surface to avoid entanglement. The display screen 8 is installed on the top surface to facilitate the operator to observe the data at eye level. The current transmission module 3 is set on the side to separate the power supply access direction from the device body. The external mounting mechanism 6 is installed on the side to make the contact angle between the data communication device and the mounting surface adjustable. The pulling mechanism 5 is installed on the side, and the pulling direction can be adjusted according to the carrying requirements with the swing function and the telescopic function.

[0052] Specifically, the power cord positioning mechanism 4 and the display screen 8 are centrally arranged on the top surface of the housing 1. The operator can directly visually see the content of the display screen 8 when standing, and the power cord 31 forms an independent management space in the top area. The current transmission module 3 and the external installation mechanism 6 are distributed on the side of the housing 1, so that the connection direction of the power cord 31 and the installation fixing direction are spatially isolated when the device is installed, avoiding interference between the cable and the installation mechanism. The swingable pulling mechanism 5 is connected to the side of the housing by a rotating shaft. When in the carrying state, it can be flipped upward to form a top handle, and can be folded down to the bottom when the device is placed, realizing free switching between the carrying posture and the placement state.

[0053] Through the above technical solution, the present invention effectively solves the problem of cross-entanglement of cables on the surface of the equipment, so that the power cord and data cable are managed in layers on the top and sides; optimizes the layout of the human-computer interaction interface so that data observation and cable operation do not interfere with each other; improves the spatial adaptability of the equipment during installation, so that the external connection components can obtain the best operating angle; enhances the convenience of carrying, and meets the needs of different transportation scenarios through the multi-directional adjustment of the lifting mechanism.

[0054] In this embodiment, a heat dissipation slot 11 is further provided on the bottom surface of the housing 1 .

[0055] In the above, the heat dissipation slot 11 refers to a hollow structure opened on the housing 1, so as to improve the ventilation performance inside and outside the housing 1.

[0056] Specifically, when the data communication module inside the housing 1 generates heat during operation, the internal temperature of the housing 1 rises, and the heat can be promptly dissipated to the outside of the housing 1 through the heat dissipation slots 11 .

[0057] Through the above technical solution, the heat dissipation slot 11 of the present invention is used for large-area heat dissipation and ventilation, thereby extending the service life.

[0058] In this embodiment, a nano thermal insulation pad 12 is further provided on the bottom surface of the housing 1 .

[0059] In the above, the nano thermal insulation pad 12 refers to a thermal insulation structure made of nanomaterials, which uses its low thermal conductivity and high porosity characteristics to block the heat transfer path.

[0060] Specifically, the nano thermal insulation pad 12 reduces heat conduction through the porous nanostructure of the material itself. When data communication equipment or substation equipment generates heat and causes the temperature to rise, the nano thermal insulation pad 12 reduces the mutual influence by slowing down the heat transfer.

[0061] Through the above technical solution, the nano thermal insulation pad 12 of the present invention is used for effective thermal insulation support and is wear-resistant and non-slip.

[0062] Specifically, the upper end surface of the shell 1 is electrically connected to the display screen 8, a silicone sleeve 33 is fixedly provided in the middle of the front end of the shell 1, the front end of the shell 1 is electrically connected to the power cord 31 through the silicone sleeve 33, the outer end of the power cord 31 is provided with a plug 32, and external mounting mechanisms 6 are installed on the front and back of both sides of the shell 1; the power cord positioning mechanism 4 is fixed in front of the upper end surface of the shell 1; the pulling mechanism 5 is movably connected to the rear end of both sides of the shell 1, and the data line interface mechanism 7 is provided at the front end of the shell 1.

[0063] Working Principle: The power cord 31 is wrapped with a metal braided mesh and a metal rubber sleeve, which is high in strength, resistant to high and low temperatures, and resistant to pulling. The metal rubber sleeve is made of stainless steel wire and has strong performance. It can maintain normal operation in high vacuum, high and low temperature, strong radiation, and various corrosive environments. It has the advantages of high sealing strength, good effect, and reusability. It is suitable for different pressure occasions and is generally used in the range of -80~800℃. The power cord 31 is placed in the groove 43 of the support base 41. The arc-shaped pressing plate 46 is flipped and covers the power cord 31. The second buckle plate 48 is pressed on the abutment piece 411. The elastic action of the first spring member 410 provides buffering and shock absorption. The pull ring 415 is held to move the pressing rod 413 inward, and the pressing rod 413 locks the second buckle plate 48. Hold the first end plate 57 and the I-shaped protrusion 510 and rotate them to move the locking screw 58 upward inside the limiting sleeve 59. Slide the first column 56 along the inside of the slide groove 53. After adjusting the position, move the locking screw 58 downward along the inside of the limiting sleeve 59 so that the locking block 54 locks the upper part of the swing rod 51. The data communication device can be lifted and carried by holding the second U-shaped rod 511 , and can be movably adjusted through the first columnar member 56 , making it more convenient to carry.

[0064] The components of the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. The problem solved by the present invention is that it is inconvenient to directly dock and install inside the substation, and it is impossible to bend and adjust at multiple angles to connect for power supply. The power cord is easily messy during carrying and transportation, the safety factor is low, and it is difficult to hold it by stretching and adjusting the length for carrying and use, and the scope of use is relatively limited. The present invention combines the above components with each other, and through the silicone sleeve 33, power cord 31 and plug 32 arranged in the middle of the front end of the shell 1, it is convenient to directly dock and install inside the substation, and it can be bent and adjusted at multiple angles to connect for power supply. The power cord positioning mechanism 4 arranged in front of the upper end face of the shell 1 facilitates the positioning and clamping of the power cord 31 during carrying and transportation, avoids the mess of the power cord 31, and improves the safety factor. The pulling mechanism 5 movably connected near the rear end on both sides of the shell 1 facilitates direct hand-held stretching and adjusting the length for carrying and use, and has a wide range of adaptability.

[0065] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description.
