DETAILED DESCRIPTION

[0074] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0075] Instrument vehicles are widely used in the oil industry to measure, detect and record parameters and data related to oil exploration, mining and transportation. They can be connected to on-site fracturing vehicles, sand blending vehicles and other equipment to achieve real-time monitoring and control of equipment operation, thereby ensuring the normal operation of the work;

[0076] The current instrument vehicle is mainly composed of components such as a vehicle, a carriage, and an internal computer. The computer is connected to related equipment through cables to collect equipment data and thus realize the control of on-site equipment;

[0077] However, if on-site control is only carried out through data collection, there will be certain instability, especially in the wireless transmission of information. Although the instrument vehicle can be connected to on-site equipment through cables, it can only be controlled online through data and actual control cannot be achieved. Therefore, improvement is urgently needed.

[0078] like Figures 1 to 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 plate 5, a functional box 6, a support assembly 7 and a sealing assembly 8;

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

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

[0081] As in the above structure, the protrusions 11 on the chassis 1 protrude toward the bottom surface, and between the protruding parts of the two protrusions 11 is a battery cavity 102, which is used to install the battery pack 4 to provide power;

[0082] The inner side of the protruding portion 11 of the chassis 1 also forms a receiving cavity 101 for installing the power assembly 3;

[0083] The instrument box 2 is movably arranged on the chassis 1 and is provided with at least one open surface. When assembling, the open surface of the instrument box 2 is installed toward the chassis 1. The instrument box 2 is movably connected to the chassis 1 through the power assembly 3. When using, the power assembly 3 drives the instrument box 2 to shift and flip so that its open surface faces outward, thereby facilitating the connection of field equipment.

[0084] Specifically, the instrument box 2 is used to install various pipe valves, detection instruments, pumps and other equipment for medium transportation, regulation and detection. After the assembly of various components is completed, a modular structure is formed, and then the device is hung on the chassis 1, which is convenient for integrated production and also convenient for assembly and maintenance.

[0085] At the same time, the instrument box 2 is flipped to open outward. After its use, it can be sealed by flipping back to its original position. Therefore, there is no need to set up a box door, which simplifies the box structure; it is also convenient for maintenance and heat dissipation.

[0086] In specific applications, after the instrument box 2 is flipped, the electronic equipment and operating equipment in the instrument box 2 can be connected to the equipment on site, which is convenient for direct detection and distribution processing of the oil field transportation medium, thereby solving the problem that the existing monitoring method is greatly affected by the stability of signal transmission, and facilitating rapid inspection of the pipeline; this provides a new inspection vehicle structure, which has inspection functions that traditional inspection vehicles do not have, is beneficial to the operation and maintenance guarantee 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 chamber 101 is divided into a power chamber 1011 in the middle and control chambers 1012 on both sides, wherein the power chamber 1011 is an open structure for accommodating the power assembly 3; the control chamber 1012 is connected to the battery chamber 102, and the control chamber 1012 is sealed by a cover plate;

[0088] As described above, the accommodating chamber 101 is further divided into a power chamber 1011 and a control chamber 1012. When used, the power chamber 1011 is provided with a power assembly 3, and the control chamber 1012 is used to install a battery module management module of the battery pack 4, so as to realize 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 assembly 3 in the power chamber 1011, thereby improving the convenience of electrical connection;

[0090] In order to ensure the normal operation of the power system, the control cavity 1012 is sealed by a cover plate to ensure the sealing performance.

[0091] like Fig.10 and Fig.12 As shown, the power assembly 3 includes a guide rail 31, a connecting plate 32 and a first push rod 33, wherein the guide rail 31 is arranged on the chassis 1; an 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 on each of the two sides of the connecting plate 32; the first push rod 33 is arranged in the power cavity 1011, and the movable end of the first push rod 33 is connected to the connecting plate 32;

[0092] As in the above structure, the instrument box 2 is driven by the connecting plate 32 and the first push rod 33 in the power assembly 3, and is displaced by the guide rail 31;

[0093] During the specific operation, the first push rod 33 drives the connecting plate 32 to move, and 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 synchronously, so that the instrument box 2 tilts and flips. 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 direct monitoring of the on-site equipment;

[0094] Furthermore, the connecting plate 32 is connected to two instrument boxes 2, so that the two instrument boxes 2 can be driven to flip at the same time. The two instrument boxes 2 can accommodate more devices, which expands the device interface and provides more detection methods.

[0095] like Figure 3 and Fig.12 As shown, the power assembly 3 further includes a slider 34, a hinge support 35 and a connecting block 36, wherein the slider 34 is slidably connected to the guide rail 31; the hinge support 35 is arranged on the slider 34; the connecting block 36 is a columnar structure, and an angle groove 301 is provided on the circumference 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 is engaged with the angle groove 301, and the instrument box 2 and the connecting block 36 are relatively fixed;

[0096] As in the above structure, 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, so that the instrument box 2 can be translated by the cooperation of the slider 34 and the guide rail 31, and the rotation can be realized by relying on the connecting block 36, so that when the first push rod 33 is actuated, the instrument box 2 can be driven to flip;

[0097] like Figure 2 and Figure 4As shown, when the instrument box 2 rotates, it can achieve an angle flip of 0 to 90 degrees, and when the first push rod 33 stops moving, the instrument box 2 will be positioned at this angle, and then its internal equipment can be connected with the field equipment, thereby realizing the field detection 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 Fig.10 As shown, the first push rod 33 includes a carrier 331 and a first push rod body 332, wherein the carrier 331 and the battery pack 4 are arranged on the same surface of the chassis 1, and the carrier 331 is mounted with a cooling circulation component of the battery pack 4; the first push rod body 332 is arranged on the carrier 331, and penetrates the chassis 1 and is connected to the connecting plate 32;

[0100] As in the above structure, in the first push rod 33, the first push rod body 332 is an action component, which is connected to the chassis 1 through the carrier 331 and penetrates the chassis 1, thereby driving the connecting plate 32 to move;

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

[0102] Furthermore, the carrier 331 is mounted with cooling circulation components of the battery pack 4, such as a pump unit for circulating the coolant of the battery pack, which can reduce the pipe interfaces in the battery pack 4, thereby significantly reducing the risk of leakage and improving the safety of the application.

[0103] like Figure 5 Fig.12 and Fig.13 As shown, the power assembly 3 also includes a second push rod 37, which includes a second push rod body 371, an angle fork 372 and a tension spring 373, wherein the second push rod body 371 is arranged in the power chamber 1011 and is relatively fixed to the chassis 1, and the second push rod body 371 is a bidirectional push rod; the angle fork 372 is arranged on the movable end of the second push rod body 371, and the movable end of the angle fork 372 abuts against the instrument box 2; one end of the tension spring 373 is connected to the angle fork 372, and the other end is connected to the second push rod body 371;

[0104] As in the above structure, the second push rod 37 in the power assembly 3 is provided with a second push rod body 371 and an angle fork 372, and the second push rod 37 is a bidirectional push rod, so when the instrument box 2 needs to be flipped and adjusted, the first push rod 33 and the second push rod 37 act synchronously, wherein the first push rod body 332 drives the connecting plate 32 to move downward to pull the connecting plate 32, and the second push rod body 371 drives the angle fork 372 to move, exerting a force to separate the two instrument boxes 2 from each other, which can eliminate the influence of the dead point position, so that the instrument box 2 can be flipped smoothly, ensuring the stability of the action; after the instrument box 2 is flipped, the second push rod 37 is reset;

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

[0106] Furthermore, the second push rod 37 is also provided with a tension spring 373, so that when the instrument box 2 is flipped and reset, the second push rod body 371 drives the two angle forks 372 to separate from each other, and then when the instrument box 2 is reset, it will be against the angle fork 372, so as to achieve a buffering effect;

[0107] Specifically, the angle fork 372 is hinged to the movable end of the second push rod body 371 and limits the rotation range of a certain angle, so as to avoid the situation that the tension spring 373 is over-tensioned when the instrument box 2 is pushed, and the angle fork 372 appears to be located on the same line with the second push rod 37. At this time, the instrument box 2 can be pushed to move and the reset buffer of the instrument box 2 can be realized;

[0108] Specifically, Fig.13 As shown, a limiting plate 374 is provided on the angle fork 372, and the second push rod body 371 is connected to the chassis 1 through the bracket 375, so that when the angle fork 372 is used to resist and buffer the instrument box 2, the tension spring 373 will be stretched, and in order to prevent the angle fork 372 from rotating excessively, the limiting plate 374 will resist against the bracket 375, thereby achieving a limiting effect;

[0109] When the two instrument boxes 2 need to be pushed apart, a tension spring 373 with a large tension force is preferably used to prevent the limit plate from abutting against the bracket 375 when the instrument box 2 is pushed. The large tension 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, thereby improving the safety of application;

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

[0112] Furthermore, the connecting plate 32 corresponds to the power cavity 1011, and a generator, an air compressor and other components are arranged in the power cavity 1011. The integrated circuit components and various valve islands on the bottom surface of the connecting plate 32 further improve the convenience of supplying energy to the inside of the instrument box 2. At the same time, before the instrument box 2 is flipped over, the circuit components and various valve islands are easy to inspect and maintain, and after flipping over, they will enter the power cavity 1011 to achieve safety protection, thereby significantly improving the stability of the application.

[0113] like Figure 2 and Fig.11 As shown, the instrument box 2 has three open faces, wherein a box plate 5 is provided at each end of the chassis 1, and the box plate 5 and the instrument box 2 are located on the same side of the chassis 1; the instrument box 2 and the power assembly 3 are provided on opposite sides of the two box plates 5; the functional box 6 is provided between the two power assemblies 3 and corresponds to the battery pack 4, and the surface of the functional box 6 corresponding to the instrument box 2 is an open structure; the support assembly 7 is provided inside the instrument box 2;

[0114] Before the instrument box 2 is adjusted by the power assembly 3, an 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, and the support assembly 7 is arranged 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 corresponding to the accommodating cavity 101 faces outward, the open surface corresponding to the adjacent instrument box 2 faces the accommodating cavity 101, and the open surface corresponding to the functional box 6 remains unchanged;

[0116] As in the above structure, when grouping, four instrument boxes 2 are provided and are arranged on both sides of the functional box 6, and the side of the instrument box 2 away from the functional box 6 is closed by the box plate 5;

[0117] Specifically, the box plate 5 may also be configured as a chamber structure for 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 box, a box door 51 is provided on the box plate 5, and the box door 51 should be set corresponding to the connecting plate 32 of the power component 3, so that no matter whether the instrument box 2 is before or after adjustment, the box can be entered through the box door 51, which is convenient for inspection and maintenance, thanks to the driving structure of the instrument box 2 through the connecting plate 32.
