Description

Technical Field

[0001] This application relates to the field of oil and gas field production enhancement technology, and in particular to a cable quick-connect mechanism and an electric-driven fracturing device. Background Technology

[0002] In fracturing operations for oil and gas field production enhancement services, electric fracturing has gradually become the mainstream method due to its environmental friendliness and economic efficiency. Therefore, electric fracturing equipment is typically used for electric fracturing operations. Before electric fracturing operations are carried out, cables need to be laid to connect the fracturing unit and frequency converter of the electric fracturing equipment. After electric fracturing operations, the cables need to be retrieved to facilitate operations at the next well site.

[0003] Currently, most well sites still rely on manual labor to lay cables during equipment deployment. Because multiple fracturing units and frequency converters need to be connected, the large number and weight of cables result in extensive manual labor during connection, often hindering rapid execution. While some well sites use cranes for cable connection, saving some labor, crane-assisted cable transport is inefficient, costly, and inflexible, still requiring significant manpower. During equipment relocation, cables need to be collected and transported. Currently, cable boxing is commonly used for collection, requiring cranes to lift the cables, which are then manually coiled and placed into the cable box – a low-efficiency and labor-intensive method. Some well sites use hydraulic reels powered by rollers, which require separate skids, are large, complex, costly, and inconvenient to transport separately. Therefore, existing cable connection methods are no longer sufficient to meet the requirements of well site operations. Utility Model Content

[0004] Based on this, the purpose of this application is to provide a cable quick-connect mechanism and an electric fracturing device including the cable quick-connect mechanism, so as to solve the problem of inconvenience caused by low work efficiency and large workload when laying and dismantling cables in the well site in the prior art.

[0005] According to one aspect of this application, a cable quick-connect mechanism is provided, comprising:

[0006] A track assembly having an opening at one end;

[0007] A telescopic component, one end of which passes through the opening into the track component and is slidably connected to the track component, and the other end of the telescopic component has a connector for connecting a cable;

[0008] A drive assembly having a drive wheel movably connected to the telescopic assembly to drive the telescopic assembly to extend out of or retract into the track assembly.

[0009] In one embodiment, the connector has a plurality of connectors, each connector being used to connect to a corresponding cable.

[0010] In one embodiment, the telescopic assembly also includes a cable clamp, which has several spaced-apart through holes that extend through opposite sides of itself, each through hole being used for one cable to pass through.

[0011] In one embodiment, the inner wall of the track assembly is provided with a guide member, and the outer wall of the telescopic assembly is provided with a guide rail corresponding to the guide member, and the guide member is slidably connected to the guide rail.

[0012] In one embodiment, the drive assembly includes a drive source, a first transmission wheel, a transmission component, and a second transmission wheel. The drive source is driveably connected to the first transmission wheel, the second transmission wheel is driveably connected to the first transmission wheel through the transmission component, and the drive wheel is coaxially connected to the second transmission wheel.

[0013] In one embodiment, the drive source is connected to the first drive wheel via a gearbox, the gearbox being configured to make the transmission ratio from the drive source to the first drive wheel greater than 1.

[0014] In one embodiment, the drive source is a handwheel or an electric motor.

[0015] In one embodiment, the drive wheel is a gear, and the outer wall of the telescopic component is provided with a rack corresponding to the gear, the gear meshing with the rack.

[0016] In one embodiment, the drive component and the telescopic component are perpendicular to each other.

[0017] According to another aspect of this application, an electrically driven fracturing apparatus is provided, comprising:

[0018] A frequency converter device includes a frequency converter body and a cable quick-connect mechanism as described in any of the above embodiments, wherein the cable of the cable quick-connect mechanism is connected to the frequency converter body, and the cable quick-connect mechanism is located on the top of the frequency converter body.

[0019] The fracturing device is arranged at an interval from the frequency converter device. When the telescopic component of the cable quick-connect mechanism extends relative to the track component, the fracturing device can be connected to the joint of the cable quick-connect mechanism.

[0020] The aforementioned cable quick-connect mechanism and the electric fracturing equipment including the cable quick-connect mechanism, on the one hand, by installing the cable within the telescopic component of the cable quick-connect mechanism, which can extend or retract into the track assembly, the cable can be quickly extended or retracted, eliminating the need for manual cable laying and retrieval, thus saving significant manpower, time, and labor costs. On the other hand, by integrating the cable quick-connect mechanism onto the inverter body, there is no need for separate storage and transfer of the transport cable, thus saving on cable transportation costs. Furthermore, by placing the cable quick-connect mechanism on the top of the inverter body, when the telescopic component extends to connect the joint to the fracturing device, the cable runs overhead, freeing up ground space, facilitating the movement of people and vehicles, and solving the problem of inconvenient equipment maintenance.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] As described in the background section, before performing electric fracturing operations, cables need to be laid to connect the fracturing unit and the frequency converter of the electric fracturing equipment. After the electric fracturing operation, the cables need to be retrieved to facilitate operations at the next well site.

[0037] Currently, during well site equipment deployment, cables are mostly laid manually by dragging them. Because multiple fracturing units and frequency converters need to be connected, the large number and weight of cables result in significant manual labor during connection, often hindering rapid execution. While some well sites use cranes for cable connections to save some labor, crane-assisted cable transport is inefficient, costly, and inflexible, still requiring substantial manpower. During equipment relocation, cables need to be collected and transported. Currently, cable box collection is common, requiring cranes to lift the cables, which are then manually coiled and placed into the cable box – a low-efficiency and labor-intensive method. Some well sites use hydraulic reels powered by rollers; these require separate skids, are large in size, complex in structure, costly, and require separate transport, making them extremely inconvenient. Therefore, existing cable connection methods are no longer sufficient to meet the requirements of well site operations.

[0038] Therefore, this application provides a cable quick-connect mechanism and an electric-driven fracturing device including the cable quick-connect mechanism. The cable quick-connect mechanism can replace manual labor for automatic cable laying and recycling, thereby saving a lot of manpower, time and labor costs, and thus achieving the goal of improving work efficiency.

[0039] The following description uses the application of a quick-connect cable mechanism in an electrically driven fracturing device for enhancing oil and gas field production as an example to illustrate the structure of the electrically driven fracturing device and the quick-connect cable mechanism provided in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the quick-connect cable mechanism of this application is not limited to being applied only to electrically driven fracturing devices, but can also be used in any equipment that requires cable laying and retrieval, and is not limited here.

[0040] The electrically driven fracturing equipment provided in the embodiments of this application includes, as follows: Figure 1 and Figure 2 The variable frequency drive (VFD) unit 10 and the fracturing unit (not shown in the figure) are arranged alternately. The fracturing unit has a fracturing pump, which injects fracturing fluid into the oil well or gas well through the reciprocating motion of the plunger to further fracture the reservoir rock, expand the reservoir fractures, increase the contact area between the reservoir and the wellbore, and improve the formation permeability, thereby increasing the productivity and production of the oil well or gas well. The VFD unit 10 is used to change the power supply frequency to control the motor speed, thereby adjusting the flow rate and output pressure of the fracturing pump in the fracturing unit. During fracturing operations at the well site, the fracturing unit and the VFD unit 10 are electrically connected to each other; after the fracturing operation is completed, the fracturing unit and the VFD unit 10 can be separated to facilitate transfer to the next well site for fracturing operations.

[0041] Specifically, in one embodiment, such as Figure 1As shown, the frequency converter device 10 includes a frequency converter body 100 and a cable quick-connect mechanism 200. The cable quick-connect mechanism 200 is connected to the frequency converter body 100, and a cable 30 is arranged in the cable quick-connect mechanism 200. Figure 1 and Figure 2 (Not shown in the diagram) and electrically connected to the inverter body 100 via cable 30, the cable quick-connect mechanism 200 has a connector 210 at the end away from the inverter body 100. Connector 210 is used to connect cable 30. When it is necessary to connect the inverter device 10 to the fracturing device, connector 210 can be connected to the fracturing device, thereby allowing the inverter device 10 and the fracturing device to be connected via cable 30 within the cable quick-connect mechanism 200. Connector 210 can be either male or female, allowing for quick insertion and removal, facilitating the operator to connect the cable 30 on the fracturing device to connector 210.

[0042] Preferably, the cable quick-connect mechanism 200 is installed on the top of the inverter body 100, so that the inverter body 100 can support the cable quick-connect mechanism 200 and allow the cable 30 to be routed in the air, thereby freeing up ground space, facilitating the movement of people and vehicles, and making it easier for operators to maintain the equipment.

[0043] exist Figure 1 and Figure 2 In the embodiment shown, there are two cable quick-connect mechanisms 200. Of course, it is understood that the number of cable quick-connect mechanisms 200 is not limited, and there can be one or more.

[0044] More preferably, the cable quick-connect mechanism 200 is a retractable structure, meaning that the cable quick-connect mechanism 200 can extend or retract relative to the inverter body 100, so that when the electric drive fracturing equipment needs to operate, such as Figure 1 As shown, the cable quick-connect mechanism 200 has a connector 210 at one end that can quickly extend to one side of the fracturing device, facilitating the operator to connect the fracturing device to the connector 210; and when the electrically driven fracturing equipment needs to be transported, such as Figure 2 As shown, the cable quick-connect mechanism 200 has a connector 210 at one end that can be quickly retracted into the inverter body 100, ensuring that the overall size of the inverter device 10 does not exceed the width limit and meets the transportation size requirements.

[0045] See Figure 3In one embodiment, the cable quick-connect mechanism 200 includes a track assembly 220, a telescopic assembly 230, and a drive assembly 240. The track assembly 220 is connected to the top of the inverter body 100 and has an opening at one end facing out of the inverter body 100. One end of the telescopic assembly 230 passes through the opening into the track assembly 220 and is slidably connected to the track assembly 220. A connector 210 is provided at the end of the telescopic assembly 230 away from the inverter body 100. The cable 30 is provided inside the telescopic assembly 230. The drive assembly 240 has a drive wheel 241, which is movably connected to the telescopic assembly 230 so as to drive the telescopic assembly 230 to extend out of the track assembly 220 or retract into the track assembly 220.

[0046] Thus, by allowing the telescopic component 230 to extend or retract relative to the track component 220, the cable 30 within the telescopic component 230 can also extend or retract quickly, eliminating the need for manual laying and retrieval of the cable 30. This enables automated operation, saving significant manpower, time, and labor costs. Furthermore, because the cable quick-connect mechanism 200 is integrated into the inverter body 100, there is no need for separate storage and transfer of the cable 30, thereby saving on cable 30 transportation costs.

[0047] Furthermore, regarding the specific structure of the track assembly 220 and the telescopic assembly 230, please refer to... Figure 4 The track assembly 220 includes a housing 221 and a guide member 222. The housing 221 is a hollow cylindrical structure with one end open, and the guide member 222 is provided on its inner wall. Correspondingly, see [reference]. Figure 5 The telescopic component 230 includes a telescopic frame 231, which is a hollow cylindrical frame structure. The cable is located inside the telescopic frame 231, and the connector 210 is located at the end of the telescopic frame 231. The outer wall of the telescopic frame 231 corresponding to the guide member 222 is provided with a guide rail 232 corresponding to the guide member 222. The guide member 222 is slidably connected to the guide rail 232, which makes it easier for the telescopic component 230 to extend and retract relative to the track component 220, and can ensure that the telescopic component 230 moves in a straight line during extension and retraction, avoiding tilting or jamming between the telescopic component 230 and the track component 220.

[0048] Optionally, in Figure 4 In the embodiment shown, the guide member 222 has two sets, and the two sets of guide members 222 are spaced apart on the bottom wall of the housing 221, such as... Figure 5 As shown, the guide rail 232 also has two corresponding guide rails, and each set of guide members 222 is slidably connected to the corresponding guide rail 232. Of course, the number of guide rails 232 and the number of guide members 222 are not limited, and are not limited to two guide rails 232 or two sets of guide members 222.

[0049] For example, in some embodiments, each set of guide members 222 may be a structure composed of multiple rollers, such that the rollers are in a rolling connection with the guide rail 232. Of course, the guide member 222 may also be a slider or the like that slidably connected to the guide rail 232, and there is no limitation here.

[0050] It is worth noting that there will be transmission of high-voltage current, low-voltage current, and control signals between the frequency converter device 10 and the fracturing device. Therefore, in some embodiments, such as Figure 5 As shown, there are several cables 30, all of which are classified into at least one type. Different types of cables 30 are configured to have different uses. Correspondingly, there are also several connectors 210, each of which is used to connect to one cable 30.

[0051] For example, in Figure 5 In the illustrated embodiment, there are multiple cables 30, all categorized into three types: high-voltage cable 31, low-voltage cable 32, and control cable 33. High-voltage cable 31 transmits high-voltage current, low-voltage cable 32 transmits low-voltage current, and control cable 33 transmits control signals. Correspondingly, there are also multiple connectors 210, including high-voltage cable connector 211, low-voltage cable connector 212, and control cable connector 213. As the names suggest, high-voltage cable connector 211 connects to high-voltage cable 31, low-voltage cable connector 212 connects to low-voltage cable 32, and control cable connector 213 connects to control cable 33. This allows the frequency converter device 10 and the fracturing device to transmit different currents and control signals after being connected via cables 30, enabling the electrically driven fracturing equipment to operate normally.

[0052] Furthermore, in a preferred embodiment, the telescopic assembly 230 further includes a cable clamp 233, which is fixedly disposed within the telescopic frame 231. The cable clamp 233 has several spaced-apart through holes extending through its opposite sides, the number of which corresponds to the number of cables 30. Each through hole is used for one corresponding cable 30 to pass through. Thus, by providing the cable clamp 233, all cables 30 can be securely fixed within the telescopic frame 231 with reasonable spacing, preventing them from tangling or knotting, thereby avoiding electromagnetic interference between the cables 30.

[0053] See Figure 6 and Figure 7In the structure of the drive assembly 240, the drive assembly 240 includes a drive source 242, a first transmission wheel 243, a transmission member 244, and a second transmission wheel 245. The drive source 242 is driveably connected to the first transmission wheel 243, the second transmission wheel 245 is driveably connected to the first transmission wheel 243 through the transmission member 244, and the drive wheel 241 is coaxially connected to the second transmission wheel 245. In some embodiments, the transmission member 244 can be a synchronous belt or a chain, etc., one end of which is sleeved on the first transmission wheel 243, and the other end of which is sleeved on the second transmission wheel 245. When the drive source 242 drives the first transmission wheel 243 to rotate around its own central axis, the first transmission wheel 243 drives the second transmission wheel 245 to rotate around its own central axis through the transmission member 244, thereby driving the drive wheel 241 to rotate.

[0054] In one embodiment, the drive wheel 241 is a gear, and the outer wall of the telescopic frame 231 of the telescopic assembly 230 is provided with a rack 234 corresponding to the gear, with the gear meshing with the rack 234. Thus, when the gear rotates, it can drive the rack 234 to move linearly, thereby enabling the telescopic assembly 230 to move linearly and achieve telescopic movement relative to the track assembly 220. Of course, the drive wheel 241 is not limited to a gear; it can also be a roller, etc.

[0055] In some alternative embodiments, the drive source 242 may be as follows: Figure 6 The handwheel 242a shown is used by the operator to rotate the first transmission wheel 243 and the second transmission wheel 245; it can also be as follows: Figure 7 The electric motor 242b shown can be powered by power supply 242c to replace the manual drive handwheel 242a in driving the telescopic assembly 230 to extend and retract.

[0056] When the drive source 242 is a handwheel 242a, in order to make it easier for the operator to crank the handwheel 242a, or when the drive source 242 is an electric motor 242b, in order to make the electric motor 242b more energy-efficient, the drive source 242 is connected to the first transmission wheel 243 through a gearbox 246. The gearbox 246 can have a structure in which gears of different diameters mesh with each other. It is configured to make the transmission ratio from the drive source 242 to the first transmission wheel 243 greater than 1, thereby having the function of deceleration and increasing torque, ensuring that manual drive is easier and electric drive is more energy-efficient.

[0057] In addition, such as Figure 3As shown, the drive assembly 240 and the telescopic assembly 230 are arranged perpendicularly to each other. Since the telescopic assembly 230 is arranged in the horizontal direction, the drive assembly 240 is arranged in the vertical direction, so that the drive source 242 is located close to the ground. Therefore, the space in the vertical direction can be fully utilized, making the overall size of the equipment smaller and also making it easier for operators to operate the drive source 242.

[0058] In summary, the electric fracturing equipment provided in this application, by setting the cable quick-connect mechanism 200 of the above embodiment in the frequency converter device 10, can automatically lay and retrieve the cable 30. It eliminates the need for operators to drag the cable 30 one by one for laying or retrieving, and also eliminates the need for other auxiliary equipment such as cranes to connect the cable 30. This saves a lot of manpower, time and cost, and solves the problem of inconvenience caused by low work efficiency and large workload when laying and disassembling the cable 30 in the well site in the prior art.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
