Description

Technical Field

[0001] This invention relates to the field of instrument vehicle technology, and in particular to an electric vehicle body structure, an oilfield engineering instrument vehicle, and its application method. Background Technology

[0002] Instrument vehicles are suitable for onshore oil and gas well cementing, fracturing, acidizing, and sand control operations. By being equipped with different control terminals and data acquisition and processing systems, they can realize full-process detection, information acquisition, display, recording, and centralized control of well site operations. Current instrument vehicles are mostly equipped with functional modules such as power distribution systems, HVAC systems, control systems, alarm systems, data acquisition systems, communication and broadcasting systems.

[0003] For example, utility model patent CN212400904U discloses a generator system for an oilfield instrument vehicle and an oilfield instrument vehicle. The generator system includes a chassis gearbox, a variable displacement pump, a hydraulic motor, and a hydraulic generator. The chassis gearbox is connected to the engine of the oilfield instrument vehicle and is also connected to the variable displacement pump to drive its operation. The variable displacement pump drives the hydraulic motor to rotate, and the hydraulic motor is connected to the hydraulic generator to drive its operation. The oilfield instrument vehicle includes the aforementioned generator system.

[0004] As in the instrument vehicle described in the above technical solution, there are two main modules: an operating area and a rest area. This is also the standard configuration of existing instrument vehicles, which mainly carry electronic equipment and rely on wireless signal transmission or partial wiring to monitor oilfield operations through data feedback. This results in problems such as the inability to actually monitor oil and gas transportation, the inability to directly process and distribute oilfield transportation media, and the inability to monitor the operation status when the wireless signal fails. Therefore, it is urgent to improve it. Summary of the Invention

[0005] In view of this, the present invention proposes an electric vehicle body structure, instrument vehicle and its application method that can facilitate pipeline connection and realize direct monitoring of oilfield equipment, so as to solve the problem that existing instrument vehicles rely too much on wireless signal transmission for information feedback.

[0021] Based on the above technical solutions, preferably, the power assembly further includes a slider, a hinge support, and a connecting block, wherein,

[0022] The slider is slidably connected to the guide rail;

[0023] The hinge support is mounted on the slider;

[0024] The connecting block has a columnar structure, and corner grooves are provided on the circumferential surface of the connecting block. The connecting block is rotatably connected to the hinge support.

[0025] The instrument box has a side-mounted locking groove, and the instrument box is fixed relative to the connecting block.

[0026] Based on the above technical solutions, preferably, the first push rod includes a carrier frame and a first push rod body, wherein,

[0027] The carrier and the battery pack are mounted on the same side of the chassis, and the carrier carries the cooling circulation components of the battery pack.

[0028] The first push rod body is mounted on the carrier and passes through the chassis to connect with the connecting plate.

[0029] Based on the above technical solutions, preferably, the power assembly further includes a second push rod, which comprises a second push rod body, a fork, and a tension spring, wherein...

[0030] The second push rod body is set inside the power cavity and is fixed relative to the chassis. The second push rod body is a bidirectional push rod.

[0031] The fork is located on the movable end of the second push rod body, and the movable end of the fork abuts against the instrument box.

[0032] One end of the tension spring is connected to the fork, and the other end is connected to the second push rod body.

[0033] Based on the above technical solutions, the preferred embodiment also includes a panel, a functional enclosure, and supporting components. The instrument enclosure has three open surfaces, among which...

[0034] There is one panel at each end of the chassis, and the panel and the instrument box are located on the same side of the chassis.

[0035] The instrument panel and power unit are located on opposite sides of both panels;

[0036] The functional enclosure is located between the two power components and corresponds to the battery pack. The side of the functional enclosure that corresponds to the instrument panel is an open structure.

[0037] Support components can be installed inside the instrument housing;

[0038] Before the instrument panel is adjusted by the power assembly, one open surface of the instrument panel is connected to the functional enclosure, one open surface corresponds to the receiving cavity, and the other open surface corresponds to the adjacent instrument panel. The support assembly is installed on the surface of the instrument panel corresponding to the adjacent instrument panel.

[0039] After the instrument box is adjusted, the open surface of the corresponding accommodating cavity faces outward, the open surface of the adjacent instrument box faces the accommodating cavity, and the open surface of the corresponding functional box remains unchanged.

[0040] Based on the above technical solutions, preferably, a sealing assembly is also included, which comprises a cover and a folding sliding door, wherein...

[0041] The cover is located on the side of the functional enclosure and between the two instrument enclosures;

[0042] The folding doors are stored inside the housing to selectively seal the open surfaces of the instrument panel.

[0043] On the other hand, the present invention provides an oilfield engineering instrument vehicle, including the above-mentioned electric vehicle body structure.

[0044] Furthermore, the present invention provides a method for applying the aforementioned instrument vehicle, comprising the following steps:

[0045] S1. Prepare the chassis and assemble the power components onto the chassis;

[0046] S2. Install electronic equipment and working equipment inside the instrument box, then hoist the instrument box onto the chassis and connect the instrument box to the power unit;

[0047] S3. Install the battery pack on the chassis and electrically connect the battery pack to the power unit, as well as the electronic equipment and working equipment in the instrument box;

[0048] S4. When in use, the second push rod pushes the two adjacent instrument boxes apart, and the first push rod descends synchronously. At this time, the instrument box slides along the guide rail, and the connecting plate pulls the instrument box to flip.

[0049] S5. After the flip is completed, the second push rod is reset, and the open surface of the instrument box faces outward, so as to connect to the on-site equipment for detection and control.

[0050] S6. After the application is completed, the first push rod rises and pushes the connecting plate to pull the instrument box to flip and reset.

[0051] The electric vehicle body structure, oilfield engineering instrument vehicle, and application method of the present invention have the following advantages over the prior art:

[0052] (1) An instrument box is installed on the chassis in a movable manner for installing electronic equipment and working equipment. When working, the instrument box can be rotated by the power component so that the open side of the instrument box faces outward. At this time, the electronic equipment and working equipment inside the instrument box can be connected to the equipment on site. This facilitates the direct detection and distribution of oilfield transport media, thereby solving the problem that the existing monitoring method is greatly affected by the stability of signal transmission and facilitating the rapid investigation of pipelines.

[0053] (2) By setting a protrusion on the chassis, a battery cavity for installing the battery pack and a housing cavity for installing the power component are formed. In this way, the installation of the battery pack and the installation of the power component do not interfere with each other. The housing cavity is divided into two parts: the power cavity and the control cavity. The power component is set in the power cavity, while the control cavity is used to install the battery module management module, which facilitates the distribution of power to the power component and has the advantage of reasonable layout.

[0054] (3) The instrument box is designed to be open to the outside by flipping. After use, it can be flipped back to be sealed, so there is no need to set up a separate door. This simplifies the box structure and realizes modular integration. It also facilitates maintenance and heat dissipation.

[0055] (4) The power assembly used to drive the instrument box to flip includes a guide rail, a connecting plate and a first push rod. Thus, by moving the first push rod, the instrument box can be pulled by the connecting plate with the connection point of the guide rail as the support point, thereby moving and flipping to achieve directional adjustment, so that the open surface of the instrument box faces outward, which has the advantage of convenient adjustment.

[0056] (5) By setting up a box panel and a functional box on the chassis, it forms a complete vehicle box structure together with the instrument box. They are interconnected and can be installed through the functional box to support the operation of the equipment in the instrument box, thus improving the convenience of application. At the same time, the instrument box, functional box and box panel are installed on the chassis in a modular structure, which has the advantages of convenient disassembly and maintenance.

[0057] (6) By installing a sealing component on the side of the functional box, which consists of a cover and a folding door, the folding door can be pulled out to seal the open surface of the instrument box as needed after the instrument box is flipped over to face outwards, so as to prevent foreign objects from entering and affecting the normal operation of the equipment.

[0074] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0075] Instrument trucks are widely used in the petroleum industry to measure, detect, and record parameters and data related to oil exploration, extraction, and transportation. They can be connected to on-site equipment such as fracturing trucks and sand mixing trucks to enable real-time monitoring and control of equipment operation, thereby ensuring the normal operation of work.

[0076] Current instrument vehicles mainly consist of a vehicle, a cargo box, and an internal computer. The computer is connected to relevant equipment via cables to collect equipment data, thereby enabling the control of field equipment.

[0077] However, relying solely on data acquisition for on-site control presents certain instabilities, particularly in wireless information transmission. Although the instrument vehicle can connect to field equipment via cables, it can only perform online control through data and cannot achieve actual control, thus requiring urgent improvement.

[0078] like Figures 1-13 As shown, the electric vehicle body structure of the present invention includes a chassis 1, an instrument box 2, a power assembly 3, a battery pack 4, a box panel 5, a functional box 6, a support assembly 7, and a sealing assembly 8.

[0079] The oilfield engineering instrument vehicle of the present invention includes the above-mentioned electric vehicle body structure and also includes a carrier 9.

[0080] like Figure 1 , Figure 6 , Figure 9 Figure 10 As shown, the chassis 1 has two protrusions 11, which are hollow to form a cavity 101. A battery cavity 102 is formed between the two protrusions 11. The cavity 101 and the battery cavity 102 are located on opposite surfaces of the chassis 1. The instrument box 2 is used to mount electronic equipment and working equipment. Multiple instrument boxes 2 are movably arranged on the chassis 1. The instrument box 2 has a rectangular box structure and at least one open surface. The power assembly 3 is disposed in the cavity 101 and is used to drive the instrument box 2 to rotate so that the open surface of the instrument box 2 faces outward. The battery pack 4 is disposed in the battery cavity 102.

[0081] As described above, the protrusion 11 on the chassis 1 protrudes towards the bottom surface, and the space between the protruding portions of the two protrusions 11 is the battery cavity 102, which is used to install the battery pack 4 to provide power.

[0082] The inner side of the protrusion 11 of the chassis 1 also forms a receiving cavity 101, which is used to install the power assembly 3;

[0083] The instrument housing 2 is movably mounted on the chassis 1 and has at least one open surface. During assembly, the open surface of the instrument housing 2 is installed facing the chassis 1. The instrument housing 2 is movably connected to the chassis 1 through the power assembly 3. During application, the power assembly 3 drives the instrument housing 2 to move and rotate so that its open surface faces outward, thereby facilitating connection to field equipment.

[0084] Specifically, the instrument box 2 is used to install various pipe valves, testing instruments, pumps and other equipment for media transportation, control and testing. After the assembly of each component is completed, it forms a modular structure, and then it is hoisted onto the chassis 1, which facilitates integrated production and also facilitates the convenience of assembly and maintenance.

[0085] Meanwhile, the instrument box 2 is designed to open outwards by flipping, and can be sealed by flipping back after use, so there is no need to set up a separate box door, which simplifies the box structure; it also facilitates maintenance and heat dissipation.

[0086] In practical applications, after the instrument box 2 is flipped over, the electronic equipment and operating equipment inside the instrument box 2 can be connected to the equipment on site. This facilitates the direct detection and distribution of oilfield transport media, thus solving the problem of the existing monitoring method being greatly affected by the stability of signal transmission, and making it convenient to quickly check pipelines. This provides a new type of inspection vehicle structure, which has detection functions that traditional inspection vehicles do not have, which is beneficial to the operation and maintenance of on-site operations, and also solves the problem of time-consuming and labor-intensive traditional manual inspection.

[0087] like Figure 8 As shown, the accommodating cavity 101 is divided into a power cavity 1011 located in the middle and control cavities 1012 on both sides. The power cavity 1011 is an open structure used to accommodate the power assembly 3. The control cavity 1012 is connected to the battery cavity 102 and is sealed by a cover plate.

[0088] As described above, the accommodating cavity 101 is further divided into two parts: a power cavity 1011 and a control cavity 1012. In application, the power cavity 1011 is used to house the power assembly 3, while the control cavity 1012 is used to install the battery module management module of the battery pack 4, thereby realizing power distribution control.

[0089] Since the power chamber 1011 and the control chamber 1012 are arranged adjacent to each other, it is convenient to distribute power to the power component 3 in the power chamber 1011, which improves the convenience of electrical connection.

[0090] To ensure the normal operation of the power system, the control chamber 1012 is sealed by a cover plate to guarantee its sealing performance.

[0091] like Figure 10 and Figure 12 As shown, the power assembly 3 includes a guide rail 31, a connecting plate 32, and a first push rod 33. The guide rail 31 is mounted on the chassis 1. One open side of the instrument box 2 is hinged and slidably connected to the guide rail 31. The diagonal side of the instrument box 2 is hinged to the connecting plate 32. An instrument box 2 is hinged to each side of the connecting plate 32. The first push rod 33 is located inside the power cavity 1011, and the movable end of the first push rod 33 is connected to the connecting plate 32.

[0092] As described above, the instrument box 2 is driven by the connecting plate 32 and the first push rod 33 in the power assembly 3, and its displacement is achieved by the guide rail 31.

[0093] In specific operation, the first push rod 33 drives the connecting plate 32 to move. At this time, the side of the instrument box 2 connected to the connecting plate 32 moves downward, and the instrument box 2 slides along the guide rail 31 in sync, causing the instrument box 2 to tilt and flip. After tilting, the open surface of the instrument box 2 will face outward, so as to facilitate the pipeline connection of the equipment in the instrument box 2 with the equipment on site, thereby realizing the direct monitoring of the equipment on site.

[0094] Furthermore, the connecting plate 32 connects to two instrument boxes 2, which can simultaneously drive the two instrument boxes 2 to rotate. The two instrument boxes 2 can accommodate more equipment, which expands the equipment interface and provides more detection methods.

[0095] like Figure 3 and Figure 12 As shown, the power assembly 3 also includes a slider 34, a hinge support 35, and a connecting block 36. The slider 34 is slidably connected to the guide rail 31; the hinge support 35 is disposed on the slider 34; the connecting block 36 has a columnar structure, and a corner groove 301 is provided on the circumferential surface of the connecting block 36, and the connecting block 36 is rotatably connected to the hinge support 35; the side of the instrument box 2 engages with the corner groove 301, and the instrument box 2 is relatively fixed to the connecting block 36.

[0096] As described above, the instrument box 2 is connected to the connecting block 36, the connecting block 36 is rotatably connected to the hinge support 35, and the hinge support 35 is connected to the slider 34. Thus, through the cooperation of the slider 34 and the guide rail 31, the instrument box 2 can be translated, and by relying on the connecting block 36, it can be rotated. Therefore, when the first push rod 33 is activated, it can drive the instrument box 2 to flip.

[0097] like Figure 2 and Figure 4As shown, when the instrument housing 2 rotates, it can achieve an angle flip of 0 to 90 degrees. When the first push rod 33 stops moving, the instrument housing 2 will be positioned at this angle, and then its internal equipment can be connected to the field equipment to realize field testing work.

[0098] Specifically, the flip angle of the instrument box 2 can be adaptively adjusted according to actual application requirements.

[0099] like Figure 7 and Figure 10 As shown, the first push rod 33 includes a carrier frame 331 and a first push rod body 332. The carrier frame 331 and the battery pack 4 are disposed on the same side of the chassis 1, and the carrier frame 331 carries the cooling circulation assembly of the battery pack 4. The first push rod body 332 is disposed on the carrier frame 331 and passes through the chassis 1 to connect with the connecting plate 32.

[0100] As described above, in the first push rod 33, the first push rod body 332 is the actuating component. It is connected to the chassis 1 through the carrier 331 and passes through the chassis 1, thereby driving the connecting plate 32 to move.

[0101] Since the instrument box 2 needs to be flipped, the first push rod 33 needs to have a large stroke when the instrument box 2 needs to be flipped 90°. Therefore, the carrier 331 is set on the bottom surface of the chassis 1, so that there is more space to install the first push rod body 332. Furthermore, the first push rod body 332 is set as a multi-stage telescopic rod to further reduce the accommodation space.

[0102] Furthermore, the carrier 331 carries the cooling circulation components of the battery pack 4, such as a pump unit for circulating the battery pack coolant. This reduces the number of piping interfaces within the battery pack 4, thereby significantly reducing the risk of leakage and improving the safety of the application.

[0103] like Figure 5 Figure 12 and Figure 13 As shown, the power assembly 3 also includes a second push rod 37, which includes a second push rod body 371, a fork 372, and a tension spring 373. The second push rod body 371 is disposed in the power cavity 1011 and is fixed relative to the chassis 1. The second push rod body 371 is a bidirectional push rod. The fork 372 is disposed on the movable end of the second push rod body 371, and the movable end of the fork 372 abuts against the instrument box 2. One end of the tension spring 373 is connected to the fork 372, and the other end is connected to the second push rod body 371.

[0104] As described above, the second push rod 37 in the power assembly 3 is provided with a second push rod body 371 and a fork 372, and the second push rod 37 is a bidirectional push rod. Thus, when it is necessary to flip and adjust the instrument box 2, the first push rod 33 and the second push rod 37 move synchronously. The first push rod body 332 drives the connecting plate 32 to move down to pull the connecting plate 32, while the second push rod body 371 drives the fork 372 to move, applying a force to separate the two instrument boxes 2. This can eliminate the influence of the dead point position, so that the instrument box 2 can be flipped smoothly and the stability of the operation can be guaranteed. After the instrument box 2 is flipped, the second push rod 37 returns to its original position.

[0105] When the instrument box 2 is reset after the application is completed, the first push rod body 332 can pull the instrument box 2 to move and reset through the connecting plate 32.

[0106] Furthermore, the second push rod 37 is also equipped with a tension spring 373. When the instrument box 2 is flipped and reset, the second push rod body 371 drives the two forks 372 to separate from each other. Then, when the instrument box 2 is reset, it will abut against the forks 372 to achieve a buffering effect.

[0107] Specifically, the fork 372 is hinged to the movable end of the second push rod body 371 and the rotation range is limited to a certain angle. This avoids the tension spring 373 being overstretched when pushing the instrument box 2, and the fork 372 being on the same line as the second push rod 37. At this time, the instrument box 2 can be pushed to move, and the instrument box 2 can be reset and buffered.

[0108] Specifically, such as Figure 13 As shown, a limit plate 374 is provided on the fork 372, and the second push rod body 371 is connected to the chassis 1 through the bracket 375. Thus, when the fork 372 abuts against the instrument box 2 for cushioning, the tension spring 373 will be stretched. In order to prevent the fork 372 from rotating excessively, the limit plate 374 will abut against the bracket 375, thereby achieving the limiting effect.

[0109] When it is necessary to push the two instrument boxes 2 to separate, it is preferable to use a tension spring 373 with a large tensile force to avoid the limit plate hitting the bracket 375 when pushing the instrument box 2. The large tensile force of the tension spring 373 is also conducive to ensuring a good buffering effect.

[0110] Specifically, since the bracket 375 is connected to the chassis 1, even if the limiting plate 374 abuts against the bracket 375, it will not cause damage to the second push rod body 371, thus improving the safety of the application.

[0111] Specifically, the first push rod body 332 and the second push rod body 371 adopt electric push rods or linear drive components such as hydraulic cylinders and pneumatic cylinders.

[0112] Furthermore, the connecting plate 32 corresponds to the power chamber 1011, and the power chamber 1011 is equipped with components such as a generator and an air compressor. The integrated circuit components and various valve islands on the bottom surface of the connecting plate 32 further improve the convenience of powering the instrument box 2. At the same time, before the instrument box 2 is flipped, the circuit components and various valve islands are easy to inspect and maintain. After flipping, they will enter the power chamber 1011 to achieve safety protection, thereby significantly improving the stability of the application.

[0113] like Figure 2 and Figure 11 As shown, the instrument panel 2 has three open surfaces. There is one panel 5 at each end of the chassis 1, and the panel 5 and the instrument panel 2 are located on the same side of the chassis 1. The instrument panel 2 and the power assembly 3 are arranged on opposite sides of the two panels 5. The functional box 6 is arranged between the two power assemblies 3 and corresponds to the battery pack 4. The surface of the functional box 6 corresponding to the instrument panel 2 is an open structure. The support assembly 7 is arranged inside the instrument panel 2.

[0114] Before the instrument box 2 is adjusted by the power component 3, one open surface of the instrument box 2 is connected to the functional box 6, one open surface corresponds to the accommodating cavity 101, and the other open surface corresponds to the adjacent instrument box 2. The support component 7 is set on the surface of the instrument box 2 corresponding to the adjacent instrument box 2.

[0115] After the instrument box 2 is adjusted, the open surface of the corresponding accommodating cavity 101 faces outward, the open surface of the adjacent instrument box 2 faces the accommodating cavity 101, and the open surface of the corresponding functional box 6 remains unchanged.

[0116] As described above, when the instruments are assembled, there are four instrument boxes 2, which are located on both sides of the functional box 6. The side of the instrument box 2 that is away from the functional box 6 is closed by the box panel 5.

[0117] Specifically, the box panel 5 can also be configured as a chamber structure for the installation of components;

[0118] like Figure 1 , Figure 2 and Figure 4 As shown, in order to facilitate the operation of the equipment inside the enclosure, the enclosure panel 5 is provided with an enclosure door 51. The enclosure door 51 is set to correspond to the connecting plate 32 of the power assembly 3. In this way, whether the instrument enclosure 2 is before or after adjustment, it can be entered through the enclosure door 51 for convenient inspection and maintenance. This is due to the drive structure of the instrument enclosure 2 through the connecting plate 32.

[0119] In some embodiments, the box panel 5 has a large thickness and is configured as a hollow structure to accommodate fire-fighting media; or the box panel 5 is configured as a shell structure with fire-fighting media containers arranged on the inside; in this way, the box panel 5 simultaneously serves to seal the instrument box 2 and provide fire protection, which makes full use of the space.

[0120] Among them, the functional enclosure 6 is used to set up functional components that support the operation of the equipment inside the instrument enclosure 2, such as various pumps, generator sets and other components, to support various pipe valves, detection instruments, pumps and other electronic equipment and operating equipment for media transportation, regulation and detection in the instrument enclosure 2;

[0121] Specifically, the instrument box 2 has an open surface that connects to the functional box 6, thus facilitating the connection of equipment inside the two boxes; even after the instrument box 2 is reversed, this open surface still corresponds to the functional box 6.

[0122] The instrument housing 2 also has an open surface that communicates with the accommodating cavity 101. After the instrument housing 2 is flipped over, the open surface will face outward, which facilitates the connection between the equipment in the instrument housing 2 and the on-site production equipment.

[0123] The instrument box 2 also has an open surface corresponding to an adjacent instrument box 2. After the instrument box 2 is flipped, this open surface will face the receiving cavity 101, which facilitates wiring to the devices inside the instrument box 2 through the battery module management module in the control cavity 1012 for power distribution. At the same time, the support component 7 is set on the surface of the instrument box 2 corresponding to the adjacent instrument box 2. It is used to support the devices inside the instrument box 2 to prevent the internal devices from becoming unstable after the instrument box 2 is flipped.

[0124] The other sides of the instrument housing 2 are enclosed structures, so that a good sealing effect can be achieved after the instrument housing 2 is reset;

[0125] Specifically, the support component 7 is composed of linear guide rails and various fastening structures to facilitate position adjustment and adapt to different equipment support requirements; that is, the equipment inside the instrument box 2 is connected and fixed to at least two sides of the instrument box 2.

[0135] S1. Prepare chassis 1 and assemble power assembly 3 onto chassis 1;

[0136] S2. Equip electronic equipment and working equipment in the instrument box 2, then hoist the instrument box 2 onto the chassis 1, and connect the instrument box 2 to the power assembly 3;

[0137] S3. Install the battery pack 4 onto the chassis 1 and electrically connect the battery pack 4 to the power assembly 3, as well as the electronic equipment and working equipment of the instrument box 2.

[0138] S4. When in use, the second push rod 37 pushes the two adjacent instrument boxes 2 apart, and the first push rod 33 descends synchronously. At this time, the instrument box 2 slides along the guide rail 31, and the connecting plate 32 pulls the instrument box 2 to flip.

[0139] S5. After the flip is completed, the second push rod 37 is reset, and the open surface of the instrument box 2 faces outward, thereby connecting to the on-site equipment for detection and control.

[0140] S6. After the application is completed, the first push rod 33 rises and pushes the connecting plate 32 to pull the instrument box 2 to flip and reset.

[0141] Specifically, the corresponding testing equipment is installed on the instrument box 2 and then integrated with the chassis 1.

The instrument box 2 is divided into two parts: a monitoring box 21 and a detection box 22. The monitoring box 21 and the detection box 22 are arranged opposite to each other on both sides of the functional box 6.

[0143] Among them, the monitoring box 21 is used to install components such as computers to integrate functional modules such as power distribution system, HVAC system, control system, alarm system, data acquisition system, communication and broadcasting system. As a traditional instrument detection vehicle structure, it coordinates work through data processing.

[0144] The detection box 22 is driven by the power component 3 and is equipped with relevant operating equipment to realize the connection and detection with the field equipment, as well as the control of media transportation and other functions.

[0145] Specifically, the vehicle 9 integrates a junction box 91 and a storage box 92. The junction box 91 is used to set wiring terminals to facilitate the connection of field equipment through wiring harnesses, such as monitoring systems, sand mixing trucks, fracturing trucks, etc., so as to realize comprehensive monitoring of the oilfield engineering process and ensure the normal production of the operation. The storage box 92 is used to store various tools or cables for connection between this instrument vehicle and field equipment.

[0146] In a specific application scenario, the detection box 22 of the instrument box 2 is used to install the fracturing manifold assembly and various sensors, such as flow and pressure sensors, on the manifold assembly, while the monitoring box 21 is used to install the monitoring computer. After the fracturing truck is connected to the pressure manifold assembly, it is monitored for actual delivery.

[0147] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
