Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and specifically relates to a wiring device. Background Technology

[0002] In recent years, with the development of oil and gas equipment, the field of oil and gas fracturing has gradually entered the era of electric fracturing. While enjoying the advantages of electric fracturing equipment such as energy saving, environmental protection, and low noise, users also suffer from pain points such as messy cable laying, complex and time-consuming laying and connection, high labor intensity, and slow well site withdrawal and transportation.

[0003] In current conventional electrically driven well sites, pluggable cables are used to connect equipment. These cables are laid directly on the ground and covered with a protective plate to prevent trampling and personnel from walking on them. However, this laying process causes wear and tear on the cables due to dragging them on the ground, affecting their lifespan and creating safety hazards. Personnel must cross the protective plate, causing inconvenience and occupying ground space. Furthermore, it hinders access for equipment maintenance in case of malfunction. Utility Model Content

[0004] The purpose of this application is to provide a wiring device that can solve problems such as easy wear and tear and safety hazards associated with cable laying methods.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a wiring device, including: a device body, a drive mechanism, and a wiring mechanism;

[0007] The wiring mechanism includes a first plug-in connector and a first cable connected to the first plug-in connector. The first plug-in connector is movably disposed on the main body of the device and is a first distance away from the bottom surface of the main body of the device.

[0008] The drive mechanism is connected to the first plug-in connector and is used to drive the first plug-in connector to move relative to the device body, so that the first plug-in connector extends or retracts relative to the device body.

[0009] In this embodiment, the wiring mechanism is positioned at a first distance from the bottom surface of the device body, allowing the wiring structure to be located away from the bottom of the device body. Furthermore, the wiring mechanism can be driven to move in an area away from the bottom of the device body via a drive mechanism, thereby enabling the connection or disconnection of cables between the wiring mechanism and other devices. Compared to the ground-laying method used in related technologies, this embodiment allows the cable to be located away from the bottom of the device body, achieving a suspended cable arrangement. This avoids wear caused by cable dragging and friction, and creates an unobstructed area between the two sets of connected devices without cable obstruction. It also eliminates the need for protective panels, improving the convenience and safety of construction personnel walking through the area. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0027] refer to Figures 1 to 7 This application discloses a wiring device 01, which includes a device body 10, a drive mechanism 20 and a wiring mechanism 30.

[0028] The main body 10 of the device is a basic component, which can provide a support and installation base for the drive mechanism 20 and the wiring mechanism 30; the wiring mechanism 30 is used to connect with the equipment to connect the cables; the drive mechanism 20 can provide power for the movement of the wiring mechanism 30 so that the wiring mechanism 30 can be connected or disconnected from the equipment.

[0029] like Figures 3 to 6 As shown, the wiring mechanism 30 includes a first plug-in connector 31 and a first cable 32. The first plug-in connector 31 is connected to the first cable 32, and the first plug-in connector 31 is movably disposed on the device body 10 and is a first distance away from the bottom surface of the device body 10. Based on this arrangement, the first cable 32 can be connected to the device through the first plug-in connector 31 to facilitate the transmission of electrical signals and control signals; and the device is connected at a high position through the first plug-in connector 31.

[0030] It should be noted that when the main body 10 of the device is placed on a bearing surface (such as the ground), the bottom surface of the main body 10 of the device is located on the bearing surface. At this time, the first distance is the distance from the first plug-in connector 31 to the bearing surface.

[0031] Furthermore, the first distance can be a constant or a variable value when the first plug-in connector 31 is extended or retracted relative to the device body 10. For example, when the first plug-in connector 31 moves in the horizontal direction, the first distance is a constant value; when the first plug-in connector 31 has displacement in the vertical direction, the first distance is a variable value. That is, the first distance is not equal when the first plug-in connector 31 is in the extended or retracted state. For example, the first distance is 5 meters in the extended state and 3 meters in the retracted state, etc.

[0032] Optionally, the first plug-in connector 31 can be slidably connected or rotatably connected to the device body 10. Of course, other connection methods are also possible, as long as the first plug-in connector 31 can extend or retract relative to the device body 10. The specific movement is not limited.

[0033] The drive mechanism 20 is connected to the first plug-in connector 31 and is used to drive the first plug-in connector 31 to move relative to the device body 10 so that the first plug-in connector 31 extends or retracts relative to the device body 10.

[0034] In this embodiment, the wiring mechanism 30 is at a first distance from the bottom surface of the device body 10, so that the wiring structure is far from the bottom end of the device body 10. Furthermore, the wiring mechanism 30 can be moved in the area far from the bottom end of the device body 10 by the drive mechanism 20, thereby enabling the connection or disconnection of the wiring mechanism 30 from the cables of other devices. Compared to the method of laying cables on the ground in related technologies, this embodiment allows the cables to be located far from the bottom of the device body 10, thus achieving a suspended cable arrangement, avoiding wear caused by cable dragging and friction. It also creates an unobstructed area between the two sets of connected devices without cable obstruction, and eliminates the need for protective panels, improving the convenience and safety of construction personnel walking through the area.

[0035] refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the drive mechanism 20 may include a first drive member 21 and a swing arm 22. The first drive member 21 is rotatably connected to the device body 10 about a first axis, the first drive member 21 is rotatably connected to the swing arm 22 about a second axis, the swing arm 22 is rotatably connected to the device body 10 about a third axis, and a first plug-in connector 31 is connected to the swing arm 22. The first axis, the second axis, and the third axis are arranged in parallel.

[0036] Optionally, the first axis, the second axis, and the third axis can all extend horizontally. For example... Figure 4 and Figure 5 As shown, point A corresponds to the first axis, point B corresponds to the second axis, and point C corresponds to the third axis.

[0037] Based on the above configuration, under the driving action of the first driving member 21, the swing arm 22 can rotate relative to the device body 10 around the third axis, thereby driving the first plug-in connector 31 to rotate relative to the device body 10, so that the first plug-in connector 31 can extend or retract relative to the device body 10; in addition, it can also avoid motion interference between the first driving member 21 and the swing arm 22.

[0038] Optionally, the first driving component 21 can be connected to the device body 10 via a first rotating shaft; the first driving component 21 can be connected to the swing arm 22 via a second rotating shaft; and the swing arm 22 can be connected to the device body 10 via a third rotating shaft; and the first, second, and third rotating shafts are arranged parallel to each other. Furthermore, the first plug-in connector 31 can be fixedly or movably connected to the swing arm 22, depending on the actual working conditions.

[0039] For example, the first driving component 21 can be a linear driving component, such as a cylinder, hydraulic cylinder, electric cylinder, etc. Of course, it can also be other forms, which are not specifically limited here. This driving method can eliminate the need for manual operation, reduce the labor intensity of personnel, and improve work efficiency while ensuring that personnel can install it.

[0040] The swing arm 22 can be a rod-like structure, such as a straight rod or a bent rod; of course, the swing arm 22 can also be a long plate-like structure, such as a rectangular long plate or an arc-shaped long plate. In some more specific embodiments, the swing arm 22 can be an arc-shaped plate-like structure.

[0041] To adjust the angle of the first plug-in connector 31, continue to refer to... Figure 2 , Figure 4 and Figure 5 The drive mechanism 20 may also include a second drive member 23, which is rotatably connected to the swing arm 22 around a fourth axis, and is rotatably connected to the first plug-in connector 31 around a fifth axis. The first plug-in connector 31 is rotatably connected to the swing arm 22 around a sixth axis, wherein the fourth axis, the fifth axis and the sixth axis are all parallel to the first axis.

[0042] Optionally, the fourth, fifth, and sixth axes can all extend horizontally. For example... Figure 4 and Figure 5 As shown, point D corresponds to the fourth axis, point E corresponds to the fifth axis, and point F corresponds to the sixth axis.

[0043] Based on the above configuration, under the driving action of the second driving member 23, the first plug-in connector 31 can rotate relative to the swing arm 22 around the sixth axis to adjust the angle of the first plug-in connector 31, thereby aligning the first plug-in connector 31 with other devices and ensuring that the first plug-in connector 31 can be connected with other devices; in addition, it can also avoid motion interference between the second driving member 23 and the first plug-in connector 31.

[0044] Optionally, the second drive unit 23 and the swing arm 22 can be connected by a fourth rotating shaft; the second drive unit 23 and the first plug-in connector 31 can be connected by a fifth rotating shaft; the first plug-in connector 31 and the swing arm 22 can be connected by a sixth rotating shaft; and the fourth, fifth and sixth rotating shafts are arranged parallel to each other.

[0045] For example, the second driving member 23 can be a linear driving member, such as a cylinder, hydraulic cylinder, electric cylinder, etc. Of course, it can also be other forms, which are not specifically limited here.

[0046] In order for the first plug-in connector 31 to connect with other devices, when the first plug-in connector 31 extends relative to the device body 10, the extension direction of the first plug-in connector 31 can form a first angle with the horizontal plane. Based on this arrangement, it can be ensured that the extension direction of the first plug-in connector 31 is aligned with the plug-in position of other devices, so as to facilitate smooth plugging and unplugging.

[0047] Optionally, the range of the first included angle can be from -75° to 75°, such as -75°, -60°, -45°, -30°, 0°, 30°, 45°, 60°, 75°, etc. Of course, other degrees are also possible, and no specific limitation is made here. It should be noted that the negative sign above indicates that the extension direction of the first plug-in connector 31 is below the horizontal plane, and does not represent a negative number.

[0048] refer to Figures 4 to 6 In some embodiments, the wiring mechanism 30 may further include a junction box 33, with at least one first plug-in connector 31 disposed in the junction box 33, and the junction box 33 connected to the drive mechanism 20. Based on this arrangement, the junction box 33 can accommodate at least one first plug-in connector 31, allowing the at least one first plug-in connector 31 to move synchronously with the junction box 33 relative to the device body 10, facilitating the connection of the at least one first plug-in connector 31 with other devices. Furthermore, the junction box 33 can also provide some protection for the first plug-in connector 31, preventing damage to it.

[0049] refer to Figure 2In some embodiments, the wiring device 01 may further include a cable routing mechanism 40, which is disposed on the device body 10, and the first cable 32 is wound around the cable routing mechanism 40. Based on this, the cable routing mechanism 40 can wind the first cable 32 to prevent the first cable 32 from being randomly placed and tangled, ensuring that the first cable 32 can smoothly extend and retract with the first plug-in connector 31. In addition, the cable routing mechanism 40 can also guide and limit the first cable 32.

[0050] like Figure 3 As shown, the cable management mechanism 40 may include a base frame 41, a winder 42, and an elastic element 43. The base frame 41 is connected to the main body 10 of the device. A portion of the first cable 32 is fixed to the base frame 41, and the first cable 32 is wound around the winder 42. The winder 42 is movable relative to the base frame 41. The elastic element 43 elastically connects the winder 42 and the base frame 41. Based on this configuration, the winder 42 guides and limits the first cable 32, ensuring smooth extension and retraction of the first cable 32. The elastic element 43 provides elastic force to the winder 42, and the winder 42 provides elasticity to the first cable 32, allowing the first cable 32 to remain taut without bending.

[0051] When the first plug-in connector 31 extends relative to the device body 10, the first cable 32 extends along with the first plug-in connector 31 and pulls the winder 42 to move relative to the base frame 41. At the same time, the elastic element 43 elastically extends. When the first plug-in connector 31 retracts relative to the device body 10, under the elastic force of the elastic element 43, the winder 42 can pull the first cable 32 back, thereby realizing the storage of the first cable 32.

[0052] Optionally, the winding device 42 can be movably connected to the base frame 41 via an elastic member 43. In some embodiments, the winding device 42 and the base frame 41 can be slidably connected, with the elastic member 43 elastically connecting the winding device 42 and the base frame 41; in other embodiments, the winding device 42 and the base frame 41 can be elastically connected via the elastic member 43. Based on this, the elastic force of the elastic member 43 can cause the winding device 42 to slide back relative to the base frame 41, thereby achieving the retraction of the first cable 32.

[0053] The winding device 42 can also be rotatably connected to the base frame 41, and the elastic element 43 elastically connects the winding device 42 and the base frame 41, so that the winding device 42 can rotate relative to the base frame 41 to return to its original position, thereby realizing the recycling of the first cable 32.

[0054] For example, the elastic element 43 can be a spring, rubber strip, etc.; the winder 42 can include a winding roller.

[0055] Continue to refer to Figure 3In some embodiments, the cable routing mechanism 40 may further include a cable routing device 44, which has multiple cable routing slots arranged side by side, and the multiple strands of first cables 32 are movably disposed in the corresponding cable routing slots. Based on this arrangement, the sidewalls of the cable routing slots can limit the movement of the first cables 32, preventing the multiple strands of first cables 32 from becoming entangled; furthermore, the cable routing slots can guide the first cables 32, ensuring that the first cables 32 can move along the cable routing slots and guaranteeing the smooth movement of the first cables 32.

[0056] refer to Figure 4 and Figure 5 In some embodiments, the device body 10 may have a receiving cavity 11, and the top of the device body 10 may be provided with an opening 12, which communicates with the inner cavity of the receiving cavity 11; the drive mechanism 20 is disposed in the receiving cavity 11, and the wiring mechanism 30 can extend out of the receiving cavity 11 or retract into the receiving cavity 11 through the opening 12.

[0057] Based on the above configuration, when no other devices need to be connected, the drive mechanism 20 can drive the wiring mechanism 30 to retract into the receiving cavity 11 through the opening 12, so that the main body of the device can provide a certain degree of protection for the wiring mechanism 30 and the drive mechanism 20; when other devices need to be connected, the drive mechanism 20 can drive the wiring mechanism 30 to extend out of the receiving cavity 11 through the opening 12, so that the first plug-in connector 31 of the wiring mechanism 30 can be connected to other devices.

[0058] Alternatively, the wiring mechanism 40 can also be housed within the receiving cavity 11, so that the main body 10 of the device can provide a certain degree of protection for the wiring mechanism 40.

[0059] refer to Figure 6 and Figure 7 In some more specific embodiments, the wiring device 01 can be used to connect the frequency converter and the fracturing equipment 02. The first cable 32 of the wiring device 01 can be connected to the frequency converter; additionally, the fracturing equipment 02 can include a second cable 021 and a second plug-in connector 022, with the second cable 021 connected to the second plug-in connector 022. Thus, with the first plug-in connector 31 and the second plug-in connector 022 connected, the frequency converter is sequentially connected to the fracturing equipment 02 via the first cable 32, the first plug-in connector 31, the second plug-in connector 022, and the second cable 021, thereby enabling the transmission of electrical and control signals between the frequency converter and the fracturing equipment 02.

[0060] In summary, the present application embodiment connects to other devices through the wiring device 01, which can avoid the situation of cables dragging on the ground, effectively avoid the situation of messy cable laying and cable dragging and abrasion that may cause safety hazards, and also eliminates the need for additional protective plates and does not block the passage between devices, ensuring safe operation and improving space utilization.

[0061] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
