Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline inspection technology, and in particular to an automatic data storage device for close-interval potential testing. Background Technology

[0002] Currently, close-interval potential testing (CIPS) is widely used in various underground pipeline integrity detection and corrosion monitoring systems as an important means of assessing the cathodic protection status of buried oil and gas pipelines. Its basic principle is to deploy high-density potential measurement points along the pipeline and collect instantaneous potential data at each point to determine whether the pipeline is effectively cathodically protected. Due to the dense distribution of test points, the large amount of data, and the complex testing environment, how to stably and efficiently record and manage the massive amounts of data generated during the testing process has become an indispensable part of the practical application of CIPS technology. Especially in field, unattended, or long-cycle inspection scenarios, the performance of the data storage device directly affects the integrity and validity of the test results.

[0003] Existing close-interval potential testing primarily employs portable potential measurement devices with external or internal storage modules for data acquisition. A common approach involves connecting the potential probe to the testing instrument and recording the measured potential values ​​in real-time to a memory or SD card via data cable or wireless signal. Some devices also include a simple display and positioning module, facilitating on-site assessment of the testing range and data collection status. In terms of structural design, most are integrated enclosed housings containing a power module, signal acquisition unit, and storage module. They offer concentrated functionality yet a compact structure, making them easy to carry and use. These devices prioritize functional integration, emphasizing streamlined operation and testing efficiency, making them suitable for short-cycle, high-frequency local inspection tasks.

[0004] However, existing close-interval potential testing equipment's storage devices have gradually revealed several significant problems during long-term use. First, high-frequency sampling often leads to heat buildup inside the equipment, and existing structures often lack active cooling systems, making it difficult to dissipate heat promptly and easily causing component aging. Second, the filtration and protection designs are relatively simple, allowing external dust and moisture to easily enter the equipment in harsh weather conditions, affecting electrical connections and data storage stability. Furthermore, most existing equipment uses a fixed structure, with the storage unit and casing as a single encapsulated unit, lacking support for quick-release module maintenance. Repairing and replacing storage media requires opening the entire casing, which is cumbersome and time-consuming. In scenarios with frequent vibrations or complex terrain, the lack of effective cushioning and shock absorption structures inside the equipment can easily lead to loosening, damage, or data loss of the memory over long-term use, compromising stability.

[0005] To address the above problems, an automatic data storage device for close-interval potential testing is proposed. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides an automatic data storage device for close-interval potential testing, aiming to solve the structural deficiencies of existing automatic data storage devices for close-interval potential testing in terms of ventilation and dust prevention, module maintenance, and impact resistance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic data storage device for close-interval potential testing, comprising a housing, a sealing door rotatably connected to the front of the housing, a protective frame slidably connected inside the housing, a memory unit placed inside the protective frame, a ventilation fan installed on the top wall of the housing, filter plates provided on both side walls of the housing, a fixing component provided on the top side of the filter plate, sliding grooves provided on both side walls of the housing, quick-release components provided inside the sliding grooves, the fixing component including a telescopic block, two telescopic springs fixedly connected to the bottom of the telescopic block, a telescopic groove provided inside the filter plate, and the telescopic block slidably connected inside the telescopic groove.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 4 This utility model provides an embodiment of an automatic data storage device for close-interval potential testing, comprising a housing 1. Both side walls of the housing 1 have several air inlets 101 to facilitate the entry of outside air for ventilation and heat dissipation. A sealing door 2 is rotatably connected to the front of the housing 1 via a rotating shaft mechanism. Two locking posts 3 are symmetrically arranged on the inner side of the sealing door 2, and two corresponding locking slots 4 are symmetrically opened on the front of the housing 1. The locking posts 3 and the locking slots 4 cooperate to achieve a stable closure of the sealing door 2, enhancing the overall sealing and dustproof performance of the housing 1. A protective frame 8 is slidably connected inside the housing 1 to install and secure the internal memory 6. The protective frame 8 adopts a hollow structure design to reduce structural weight and improve airflow efficiency, preventing heat accumulation in localized areas. To enhance the shock resistance of the memory 6, a buffer component 12 is provided at the rear of the protective frame 8 to effectively mitigate the impact of mechanical vibrations generated during movement or transportation on the memory 6. An exhaust fan 7 is installed on the top wall of the housing 1 to actively ventilate and expel heat from the inside of the device. To prevent dust from entering with the air, filter plates 5 are installed on the inner sides of both side walls of the outer casing 1. A fixing component 9 is connected to the top side of the filter plate 5, and the filter plate 5 is pressed and fixed by the fixing component 9. In order to improve the efficiency of equipment maintenance, sliding grooves 10 are provided on both side walls of the outer casing 1. A quick-release component 11 is installed inside the sliding groove 10. The quick-release component 11 works with the fixing component 9 to improve the stability of quick release.

[0033] Reference Figure 2 - Figure 3The fixing component 9 includes a telescopic block 901, with two telescopic springs 902 fixedly connected to its bottom. This structure allows the telescopic block 901 to elastically extend and retract in the vertical direction when pushed by an external force, thereby providing a stable clamping force to ensure the filter plate 5 is securely and reliably installed. A telescopic groove 903 for limiting and guiding is provided inside the filter plate 5 at a corresponding position. The telescopic block 901 is slidably connected inside the telescopic groove 903, ensuring that it slides along the groove direction without shifting during installation, further enhancing the assembly accuracy and structural compatibility of the filter plate 5. Meanwhile, to facilitate the quick disassembly and reinstallation of the filter plate 5, a quick-release assembly 11 is also provided inside the outer casing 1. The quick-release assembly 11 includes a fixing block 1101, which is fixedly connected to one side of the top wall of the slide groove 10 and fits against the top surface of the telescopic block 901 to form a stable pressing interface. When the filter plate 5 is inserted into the side wall of the outer casing 1, the end face of the telescopic block 901 contacts the bottom end of the fixing block 1101. After being pressed, the telescopic block 901 slides into the interior of the filter plate 5 and extends out again between the fixing block 1101 and the slider 1102. The telescopic block 901 is stuck between the two, and at this time the filter plate 5 is difficult to remove. In addition, a slider 1102 is slidably connected to the other side of the top wall of the slide groove 10. A T-shaped top seat 1103 is fixedly connected to the top of the slider 1102. The T-shaped top seat 1103 can slide and fit in the limiting slide groove opened at the top of the slide groove 10 to achieve lateral limiting and stable positioning in the structure. To improve the fit and structural flexibility of the T-shaped top seat 1103 with the limiting groove during sliding, a resistance spring 1104 is provided between its front end and the limiting groove. The resistance spring 1104 can generate a certain elastic damping during sliding. When the filter plate 5 needs to be disassembled, it can be pushed inward until the telescopic block 901 at its top contacts the slider 1102. Due to the tension of the resistance spring 1104 on the slider 1102, the telescopic block 901 is pressed and retracts back into the filter plate 5 until it slides past the slider 1102 and then slides out again. At this time, pulling the filter plate 5 outward will cause the telescopic block 901 to move the slider 1102. Since the slider 1102 and the fixed block 1101 are symmetrical, when the slider 1102 overcomes the elastic force of the resistance spring 1104 and contacts the fixed block 1101, the telescopic block 901 is once again pressured by the slider 1102 and retracts back into the filter plate 5. Since the fixed block 1101 and the slider 1102 are attached together, their end faces allow the telescopic block 901 to pass through, so the filter plate 5 can eventually be pulled out for replacement.

[0034] Reference Figure 4Considering the potential vibrations and impacts that the equipment may experience during transportation, movement, and on-site operations, a protective frame 8 is installed inside the outer casing 1 to support and protect the memory module 6. Its sidewalls are designed with a hollow structure. This hollow design not only effectively reduces the weight of the protective frame 8 itself, thus reducing the overall load on the equipment, but also significantly improves the internal airflow efficiency and heat dissipation performance, thereby helping to ensure the stability and data security of the memory module during long-term operation. To further enhance the adaptability of the device in complex or vibrating environments, a buffer assembly 12 is installed at the rear of the protective frame 8. This assembly absorbs some energy when the equipment is subjected to external mechanical impacts, mitigating the direct impact on core components. The buffer assembly 12 includes a limiting block 1201. The top of the limiting block 1201 is fixedly connected to the outside of the protective frame 8, ensuring that it forms an integral structure with the protective frame 8 to enhance overall rigidity. Simultaneously, the limiting block 1201 is slidably connected to the inside of the outer casing 1, allowing it to slide freely within a certain range when subjected to impacts or vibrations, thereby buffering displacement and dispersing energy. To achieve more effective buffering and shock absorption, the front end of the limiting block 1201 is provided with multiple buffer springs 1202. These springs are evenly arranged and installed between the limiting block 1201 and the outer shell 1 by pre-compression. When the equipment is displaced or subjected to external force, the buffer springs 1202 can deform to absorb part of the kinetic energy and return to their original position after the external force is released, thereby minimizing the negative impact of the impact on the internal memory 6 of the protective frame 8.

[0035] Working principle: After the equipment is started and put into use, outside air enters the device through multiple air inlets 101 on both sides of the outer casing 1, and is initially filtered for impurities by the internal filter plate 5. The filter plate 5 is fixed to the inside of both sides of the outer casing 1 by a combination structure of the fixing component 9 and the quick-release component 11. The telescopic block 901 is engaged between the fixing block 1101 and the slider 1102 under the action of the telescopic spring 902, forming a pressed state. After the ventilation fan 7 at the top is started, a ventilation cycle is formed by the air inlets 101 and the exhaust from the top fan, which quickly removes the heat generated by the circuit operation inside the equipment.

[0036] Meanwhile, the protective frame 8 inside the device is installed inside the outer shell 1 by sliding. Its side wall has a hollow structure. The data storage device 6 is placed inside the frame. The rear of the protective frame 8 is provided with a buffer assembly 12, which consists of a limiting block 1201 and multiple buffer springs 1202 arranged at the front end. The limiting block 1201 is slidably connected to the inside of the outer shell 1 and can generate a limited stroke displacement when vibrating. During this process, the buffer springs 1202 undergo elastic deformation to absorb kinetic energy.

[0037] During the disassembly of filter plate 5, the operator pushes it inward. The telescopic block 901 first contacts the slider 1102, and under the action of the resistance spring 1104 at its front end, it is gradually compressed back into the filter plate 5. When the telescopic block 901 slides past the slider 1102 and extends again, by pulling the filter plate 5 outward, the slider 1102 can be driven to fit against the fixing block 1101. Since the two are symmetrical structures, the telescopic block 901 is pressed back by the inclined surfaces of the two and allowed to pass through. The clamping relationship on both sides is released, and the filter plate 5 can be smoothly pulled out for replacement.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
