Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ground module preparation devices, and particularly relates to a DC grounding electrode adjacent natural gas pipeline stray current drainage ground module preparation device. BACKGROUND

[0002] With the increasing growth of power demand, the reverse nature of energy distribution and demand makes it necessary to optimize the large-scale allocation of resources, prompting a new trend in the development of long-distance high-voltage direct current transmission. At present, China has constructed a number of HVDC projects. As of 2020, 38 high-voltage direct current transmission projects with a transmission capacity of 191 million kilowatts have been completed in China. China's large-scale crude oil, refined oil and natural gas long-distance pipelines are widely distributed. As of 2020, the total length of oil and gas pipelines in China was 150,000 kilometers. The large-scale application of high-voltage direct current transmission systems inevitably intersects or is in close proximity to oil and gas pipelines. Based on the operating characteristics of high-voltage direct current transmission systems, the grounding electrode will produce certain direct current interference to nearby metal structures, especially oil and gas pipelines. High-voltage direct current transmission systems and oil and gas pipelines form a shared corridor in many areas, making the electromagnetic interference of direct current transmission projects on nearby buried metal pipelines increasingly prominent. In particular, when the grounding electrode operates in a single pole earth mode, a high-amplitude interference potential will be generated on the pipeline, which may pose safety risks such as electric shock, equipment burnout, pipeline corrosion and hydrogen embrittlement.

[0003] General methods for mitigating direct current interference include drainage protection, cross-connection protection and cathodic protection. The direct current interference protection standard GB 50991-2014 issued by China proposes a variety of mitigation measures. Certain serious high-voltage direct current transmission system interference has a wide range and large ground current, far exceeding the level of general direct current interference. There is still a lack of unified solution to the comprehensive protection measures for the grid side and the pipeline side affected by direct current ground current. At present, drainage is required for some buried oil and gas pipelines adjacent to high-voltage direct current grounding electrodes, and the use of grounding drainage modules is the most common solution.

[0004] In the process of preparing the grounding drainage module for the buried pipeline, the conductive microparticle (generally including graphite microparticle, bentonite, metal short fiber, short carbon fiber and other conductive microparticles) and other raw materials need to be mixed thoroughly. Since the conductive microparticles have a small particle size, they are prone to clumping due to moisture during storage, which affects the uniformity of the mixing and stirring of the device. In addition, the gaps between the conductive microparticles of different particle sizes are small, which affects the drying effect of the device, thereby affecting the preparation efficiency of the device. Therefore, certain improvements are needed. SUMMARY

The gas conveying pipe 605 drives the crushing block 611 to move through the connecting block 606. The connecting block 606 is arranged between the fixed box 2 and the feeding port 12, and one side of the connecting block 606 is fixedly connected with the outer side wall of the fixed box 2. A second inner cavity 612 is arranged in the connecting block 606. One side of the inside of the second inner cavity 612 is provided with an inflation air bag 607.

The rotating shaft 4 drives the cam 601 to rotate in the rotating process, and the cam 601 continuously extrudes the sliding block 602, the gas storage air bag 603 and the first spring 604, and the gas in the gas storage air bag 603 is transported to the inside of the inflatable air bag 607 through the gas pipe 605.

The linkage effect between the sliding plate 608 and the connecting rod 609 transmits power to the connecting rod 609, and the connecting rod 609 drives the crushing block 611 to assist in crushing the caked raw materials on the vibrating screen 13, prevents the caked raw materials from blocking the feed inlet 12, affects the use performance, prevents resource waste, and improves the portability of the device in the preparation process.

[0048] The auxiliary cleaning assembly 7 includes two mounting sleeves 701, which are arranged on both sides of the first stirring blade 9 and fixedly connected to the outer circumferential side of the rotating shaft 4. The outer circumferential side of the mounting sleeve 701 is fixedly connected with two mounting blocks 702, and the inside of the mounting block 702 is provided with a third inner cavity 703 on one side. The third inner cavity 703 is arranged on the side away from the mounting sleeve 701, and a memory alloy 704 is fixedly connected to the inside of the third inner cavity 703. One side of the memory alloy 704 is fixedly connected with a heat absorbing block 705, and the heat absorbing block 705 is arranged in the mounting block 702. The mounting block 702 is connected with a scraper 708. When the first stirring blade 9 drives the scraper 708 to rotate, the heat absorbing block 705 transmits the absorbed heat to the memory alloy 704, and the memory alloy 704 deforms to move the scraper 708 away from the inner side wall of the box 1. The memory alloy 704 is fixedly connected with a limiting block 706 on the side away from the heat absorbing block 705. The limiting block 706 is slidingly connected in the third inner cavity 703, and the other side of the limiting block 706 is fixedly connected with a guide rod 707.

[0049] Specifically, in the process of auxiliary drying, the heat absorption block 705 continuously absorbs the heat inside the raw materials and transmits the heat to the memory alloy 704, so that the memory alloy 704 is bent and deformed when heated. The memory alloy 704 drives the limiting block 706 to move inside the third inner cavity 703 during the bending deformation process. The linkage effect between the limiting block 706 and the guide rod 707 transmits power to the guide rod 707, so that the guide rod 707 drives the scraper 708 to move away from the inner side wall of the box 1. At this time, the first stirring blade 9 and the second stirring blade 10 still stir and mix the raw materials. The scraper 708 effectively reduces the friction between the box 1 during the mixing process, thereby assisting to improve the service life of the inner side wall of the box 1, and effectively reducing unnecessary energy loss of the device during mixing. After the stirring and mixing is completed, the heater 503 is stopped, and the raw materials are transported to the outside mold through the discharge port at the bottom of the box 1 for filling preparation. At this time, as the heat inside the box 1 continuously decreases, the memory alloy 704 will return to the original use state. At this time, the memory alloy 704 drives the limiting block 706, the guide rod 707 and the scraper 708 to move towards the inner side wall of the box 1, so that the scraper 708 contacts the inner side wall of the box 1. The driving motor 3 drives the shaft 4, the mounting sleeve 701 and the mounting block 702 to rotate, which transmits power to the scraper 708, so that the scraper 708 assists in cleaning the inner side wall of the box 1, preventing the raw materials from adhering to the inner side wall of the box 1.
