DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the conveying structure 5 includes a mounting frame 501 mounted on the storage tank 2 and a rotating pipe 502 rotatably connected to the mounting frame 501, a conveying pipe 503 is installed at the outlet of the oil pump 405, the conveying pipe 503 is wound around the rotating pipe 502, and the other end of the conveying pipe 503 is fixedly connected to the rotating pipe 502, a fixing plate 505 is fixedly connected to the storage tank 2, a rotating joint 506 is installed on the fixing plate 505, one end of the rotating pipe 502 is installed on the rotating joint 506, and the other end of the rotating joint 506 is installed with a fixing pipe 507, A second motor 508 is installed on the mounting frame 501, the rotating tube 502 is fixedly connected to the output shaft of the second motor 508, two retaining rings 504 are fixedly connected to the rotating tube 502, and the delivery pipe 503 is connected to the rotating tube 502. When it is necessary to take the fuel in the storage tank 2 for testing, the hydraulic rod 402 can be started first. When the telescopic end of the hydraulic rod 402 is extended or contracted, the mounting rod 403 will be driven to move, and the mounting rod 403 will drive the sampling tube 404 to move up and down in the storage tank 2. The sampling tube 404 can move up and down, so that it is convenient to sample the fuel at different positions. In order to detect the overall quality of the fuel, when sampling, the oil pump 405 is started, and the oil pump 405 will pump the fuel from the sampling tube 404 to the oil inlet pipe 406, and then transport it from the delivery pipe 503 at the outlet of the oil pump 405 to the fixed pipe 507, and then the fuel sample is transported to the quality inspection equipment through the subsequent delivery system, so that the quality inspection equipment can detect the sample. When the telescopic end of the hydraulic rod 402 is extended, the second motor 508 can be started, and the output shaft of the second motor 508 rotates to drive the rotating tube 502 to rotate. When the rotating tube 502 rotates, the delivery pipe 503 is released. When the hydraulic rod 40 When the telescopic end of 2 is retracted, the second motor 508 drives the rotating tube 502 to rotate, so that the delivery tube 503 is rolled up onto the rotating tube 502. The rotating tube 502 is rotated to facilitate the rolling up of the delivery tube 503. Through the setting of the rotary joint 506, the rotation of the rotating tube 502 will not affect the delivery of the fuel, and the sampling tube 404 cooperates with the subsequent delivery system to directly deliver the fuel to the quality inspection equipment for testing. During the testing process, no manual operation is required. At the same time, the fuel will not contact the outside world during the whole process, so as to prevent dust or other pollutants in the air from entering the fuel and affecting the testing effect.

[0033] Specifically, Figure 1 , Figure 4 ,and Figure 6As shown, the stirring structure 3 includes a mounting shaft 301 rotatably connected to the storage tank 2 and a plurality of stirring rods 302 fixedly connected to the mounting shaft 301. A first motor 303 is installed on the storage tank 2. The mounting shaft 301 is fixedly connected to the output shaft of the first motor 303. A protective cover 304 is installed on the storage tank 2. During detection, the properties of the fuel at different positions can be observed based on the detection data. When the properties differ greatly, the first motor 303 can be started. When the output shaft of the first motor 303 rotates, the mounting shaft 301 is driven to rotate. The mounting shaft 301 drives the stirring rod 302 to rotate. When the stirring rod 302 rotates, the fuel in the storage tank 2 is stirred. By stirring the fuel in the storage tank 2 with the stirring rod 302, the fuel can be mixed evenly, thereby ensuring that the sample taken can better represent the quality of the overall fuel.

[0034] Specifically, Figure 3 , Figure 7 and Figure 8As shown, the filtering structure 6 includes an installation box 601 fixedly connected to the bottom of the fixed pipe 507 and a connection frame 602 detachably connected to the installation box 601, a filter screen 603 is installed in the connection frame 602, a sealing ring 604 is fixedly connected to the connection frame 602, the sealing ring 604 is engaged with the installation box 601, a connecting pipe 605 is fixedly connected to the installation box 601, the fixed pipe 507 is connected to the top of the filter screen 603, the connecting pipe 605 is connected to the bottom of the filter screen 603, and the connecting frame 602 is connected to the installation box 601 through the installation structure 7. The installation structure 7 includes a connecting plate 701 fixedly connected to the connecting frame 602 and a guide frame 702 fixedly connected to the installation box 601. A driving block 703 is slidably connected to the guide frame 702. A screw rod 704 is threadedly connected to the guide frame 702. The screw rod 704 is rotatably connected to the driving block 703. The cross section of the connecting plate 701 is a triangular structure, and the cross section of the driving block 703 is a trapezoidal structure. A guide rod 705 is fixedly connected to the driving block 703. The guide rod 705 is slidably connected to the guide frame 702. The screw rod 704 is The top is fixedly connected with a rotating rod 706, and the pipeline of the external delivery system will be connected to the connecting pipe 605. When the sampled fuel enters the installation box 601 from the fixed pipe 507, the filter 603 will filter the impurities in the fuel to prevent the impurities from entering the detection equipment through the delivery system and clogging the sampling system, sensor and other components of the detection equipment, affecting the accuracy and stability of the detection. When it is necessary to replace the filter 603, the screw rod 704 is driven to rotate by the rotating rod 706, and the screw rod 704 and the guide frame 702 are threaded to drive the drive block 703 to move upward, and the drive block 703 drives the guide frame 702 to move upward. The guide rod 705 is slidably matched with the guide frame 702. The setting of the guide rod 705 makes the movement of the driving block 703 more stable. At the same time, the driving block 703 no longer blocks the connecting frame 602. At this time, the connecting frame 602 can be disassembled to replace the filter screen 603. During installation, the driving block 703 is driven downward by the screw rod 704. When the inclined surface of the driving block 703 contacts the inclined surface of the connecting plate 701, the driving block 703 continues to move downward, which is convenient for pressing the connecting frame 602 into the installation box 601, so that the sealing ring 604 and the installation box 601 are more tightly engaged, thereby improving the sealing effect.

[0035] When the present invention is in use, when it is necessary to test the fuel in the storage tank 2, the hydraulic rod 402 can be started first. When the telescopic end of the hydraulic rod 402 is extended or contracted, it will drive the installation rod 403 to move. The installation rod 403 will drive the sampling tube 404 to move up and down in the storage tank 2. The sampling tube 404 can move up and down, so that it is convenient to sample the fuel at different positions, so as to detect the overall quality of the fuel. When sampling, the oil pump 405 is started, and the oil pump 405 will draw the fuel from the sampling tube 404 to the oil inlet pipe 406, and then transport it from the delivery pipe 503 at the outlet of the oil pump 405 to the fixed pipe 507, and then the fuel sample is transported to the quality inspection equipment through the subsequent delivery system, so that the quality inspection equipment can test the sample. When the telescopic end of the hydraulic rod 402 is extended, The second motor 508 can be started, and the output shaft of the second motor 508 rotates to drive the rotating tube 502 to rotate. When the rotating tube 502 rotates, the delivery tube 503 is released. When the telescopic end of the hydraulic rod 402 contracts, the rotating tube 502 is driven by the second motor 508 to rotate, so that the delivery tube 503 is rolled up onto the rotating tube 502. The rotating tube 502 is rotated to facilitate the rolling up of the delivery tube 503. Through the setting of the rotary joint 506, the rotating tube 502 will not affect the transportation of the fuel when it rotates, and the sampling tube 404 cooperates with the subsequent transportation system to directly transport the fuel to the quality inspection equipment for testing. During the testing process, no manual operation is required. At the same time, the fuel will not contact the outside world during the whole process, so as to prevent dust or other pollutants in the air from entering the fuel and affecting the testing effect.

[0036] During the inspection, the properties of the fuel at different positions can be observed according to the inspection data. When the properties are quite different, the first motor 303 can be started. When the output shaft of the first motor 303 rotates, the installation shaft 301 is driven to rotate. The installation shaft 301 drives the stirring rod 302 to rotate. When the stirring rod 302 rotates, the fuel in the storage tank 2 is stirred. The stirring rod 302 stirs the fuel in the storage tank 2, so that the fuel can be mixed evenly, thereby ensuring that the sample taken can better represent the quality of the overall fuel.

[0037] The pipeline of the external delivery system will be connected to the connecting pipe 605. When the sampled fuel enters the installation box 601 from the fixed pipe 507, the filter 603 will filter the impurities in the fuel to prevent the impurities from entering the detection equipment through the delivery system and clogging the sampling system, sensor and other components of the detection equipment, affecting the accuracy and stability of the detection. When it is necessary to replace the filter 603, the screw rod 704 is driven to rotate by the rotating rod 706. The screw rod 704 and the guide frame 702 are threaded to drive the driving block 703 to move upward. When the driving block 703 moves upward, it drives the guide rod 705 and the guide frame 702 to rotate. The guide rod 705 slides together with the frame 702, and the setting of the guide rod 705 makes the movement of the driving block 703 more stable. At the same time, the driving block 703 no longer blocks the connecting frame 602. At this time, the connecting frame 602 can be disassembled to replace the filter screen 603. During installation, the driving block 703 is driven to move downward by the screw rod 704. When the inclined surface of the driving block 703 contacts the inclined surface of the connecting plate 701, the driving block 703 continues to move downward, which makes it easy to press the connecting frame 602 into the installation box 601, so that the sealing ring 604 and the installation box 601 are more tightly engaged, thereby improving the sealing effect.
