Description

Technical Field

[0001] The invention relates to the technical field of liquid-carrying measurement and calibration equipment, and in particular to a liquid-carrying measurement and calibration device for an external floating roof vertical metal tank and a method thereof. Background Art

[0002] The external floating roof vertical metal tank liquid metering and calibration device is mainly used for storing and measuring liquids. It is commonly found in the petroleum, chemical and other industries. The external floating roof can float with the changes in liquid level, reducing the evaporation loss on the liquid surface, while providing better sealing to prevent external contamination. It is used to accurately measure the inflow and outflow of liquids.

[0003] Among them, external floating roof vertical metal tanks are often used outdoors. When it rains, rainwater will accumulate on the external floating roof, and the accumulated rainwater is usually discharged through a drain pipe. However, in heavy rain weather, the wind speed is often strong, and the rainwater may carry leaves and plastic garbage. The leaves and garbage may cause the drain pipe to be blocked, making it difficult for the drain pipe to discharge the rainwater in time, resulting in excessive accumulation of rainwater, which increases the weight of the floating roof and may cause changes in the pressure in the tank, affecting the performance of the measuring and calibration device and possibly causing a decrease in calibration accuracy. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a liquid-carrying measurement and calibration device for a vertical metal tank with an external floating roof, comprising a drainage mechanism, the drainage mechanism also comprising a metal tank, a floating roof is slidably connected to the inner wall of the metal tank, a fixed column is fixedly connected to the top of the floating roof, and a connecting frame is rotatably connected to the inner wall of the fixed column; The crushing mechanism comprises three connection shells 1 fixedly connected to the side wall of the connection frame, three connection shells 2 fixedly connected to the side wall of the connection frame, spring piston plates are slidably connected to the inner walls of the three connection shells 1, and the parts contained in the three connection shells 1 are the same, and the parts contained in the three connection shells 2 are the same; The collecting mechanism comprises two rollers rotatably connected to the inner wall of the connecting shell 2, four laminating plates are fixedly connected to the inner wall of the connecting shell 2, the four laminating plates are grouped in pairs, and the side walls of the two groups of laminating plates are fixedly connected with fixing rings.

[0005] Preferably, the drainage mechanism further comprises a motor fixedly connected to the inner wall of the fixed column, the top output end of the motor is fixedly connected to the bottom of the connecting frame, the top of the floating roof is fixedly connected to a drum screen, the bottom of the floating roof is fixedly connected to a metering calibrator, and the inner wall of the floating roof is connected through three drainage pipes; Among them, a connecting ring is fixedly connected to the outer wall of the fixed column, a gear ring is fixedly connected to the outer wall of the connecting ring, and three fixed cylinders are fixedly connected to the side wall of the connecting frame. The three fixed cylinders contain the same parts. When encountering heavy rainfall, rainwater will slide down from the top of the floating roof and gather at the center of the floating roof. The rainwater will be discharged through the drain pipe. The rainwater will pass through the drum screen during the sliding process. The drum screen will block the leaves or plastic garbage carried by the rainwater, and then start the motor to drive the connecting frame to rotate, so that the fixed cylinder rotates around the drum screen.

[0006] Preferably, the drainage mechanism also includes a spiral rod rotatably connected to the inner wall of the fixed cylinder, the top of the spiral rod is fixedly connected to a gear, the outer wall of the gear is meshed with the inner wall of the gear ring, the outer wall of the fixed cylinder is rotatably connected to a protective door, the outer wall of the spiral rod is slidably connected to a pushing block, and the inner wall of the fixed cylinder is fixedly connected to a collecting plate. When the fixed cylinder moves, the spiral rod is driven to rotate, so that the gear is meshed with the gear ring and the gear is allowed to revolve, thereby causing the spiral rod to revolve. When the spiral rod revolves, it will contact the outer wall of the drum screen. When the spiral rod contacts leaves or plastic garbage, since there is a sawtooth block on the outer wall of the spiral rod, the sawtooth block will crush the leaves and hook the plastic garbage. The plastic garbage will be separated from the drum screen due to the revolution of the spiral rod. As the spiral rod rotates, the plastic garbage will contact the drum wall of the fixed cylinder, so that the plastic garbage is squeezed, and the plastic garbage will be affected by the rotation of the spiral rod. The friction force will break the plastic waste, and the broken plastic waste will be driven by the spiral rod to rise to the top of the spiral rod. When the spiral rod revolves, the spiral rod drives the pushing block to rotate through the slider. When the pushing block contacts the broken garbage, the pushing block will push the garbage to move to the collecting plate. As the pushing block continues to rotate, the pushing block will contact the convex block of the collecting plate. Since the contact surfaces of the pushing block and the collecting plate are both inclined surfaces, the pushing block will rise to separate the garbage from the pushing block, so that the garbage falls on the collecting plate and is collected. The garbage in the rainwater is cleaned and collected, and the holes of the drum screen are prevented from being blocked by leaves and plastic garbage on a large scale, ensuring that rainwater can be discharged stably and avoiding rainwater accumulation on the floating roof, which leads to an increase in the weight of the floating roof. This ensures the stability of the pressure in the metal tank, allowing the metering calibrator to accurately measure the liquid content in the metal tank.

[0007] Preferably, the crushing mechanism also includes a concave-convex ring fixedly connected to the bottom of the connecting ring, a water spray plate is fixedly connected to the inner wall of the connecting shell one, the top of the spring piston plate is slidably connected to the bottom of the concave-convex ring, and a sliding rod is fixedly connected to the outer wall of the spring piston plate. By utilizing the force of the movement of the connecting frame, when the connecting frame rotates, it will also drive the connecting shell one and the connecting shell two to rotate around the drum screen, driving the spring piston plate to move, so that the spring piston plate contacts the bottom of the concave-convex ring. Since the concave-convex ring is wavy, when the spring piston plate moves to the raised position of the concave-convex ring, it will be squeezed and move downward while accumulating rebound force, driving the sliding rod to move.

[0008] Preferably, the crushing mechanism also includes a baffle fixedly connected to the inner wall of the connecting shell, the inner wall of the baffle is slidably connected with a sliding plate, the inner wall of the sliding plate is rotatably connected with seven rolling rollers, the top of the sliding plate is fixedly connected to the bottom of the sliding rod, and six nozzles are fixedly connected to the inner wall of the water spray plate to make the sliding plate descend. When the spring piston plate descends, rainwater entering the connecting shell one will be squeezed and sprayed out through the nozzles on the water spray plate to the holes of the drum screen. When the spring piston plate moves to the recessed position of the concave and convex ring, the rebound force of the spring piston plate will be released, so that the spring piston plate rises, driving the sliding plate to rise, and the sliding plate moves back and forth in this way. The sliding plate will drive the rolling rollers to move back and forth, rubbing the crushed leaves to crush them again, and cooperating with the rainwater sprayed by the water spray plate to separate the leaves from the outer wall and holes of the drum screen, so as to avoid the crushed leaves from adhering to the outer wall and holes of the drum screen, thereby ensuring the continuity of rainwater flow, reducing water flow resistance and quickly draining water.

[0009] Preferably, the collecting mechanism further comprises five collecting grooves provided on the inner wall of the drum, the inner walls of the five collecting grooves are all slidably connected with spring return plates, the bottom of the inner wall of the connecting shell 2 is slidably connected with a scraper, and the top of the scraper is slidably connected with a rotating frame; Among them, the outer wall of the rotating frame is slidingly connected to the inner wall of the connecting shell two, the side wall of the sliding plate is slidingly connected to the inner wall of the rotating frame, and the outer wall of the fixed ring is rotationally connected to the inner wall of the drum. The force of the moving connecting shell two will drive the drum to move when the connecting shell two rotates around the drum screen. When the drum and the drum screen are in contact, the friction between the drum and the drum screen causes the drum to revolve, and the impurities floating on the outer wall of the drum screen are sprayed out by the water spray plate. As the rainwater in the water spray plate is sprayed out, the impurities will move to both sides of the sliding plate, and some impurities will enter the collecting trough, and the rainwater will be blocked by the baffle and the fitting plate to prevent the rainwater from entering the connecting shell two.

[0010] Preferably, the collecting mechanism further comprises a collecting hood fixedly connected to the outer wall of the connecting shell 2, a spring plate is slidably connected to the inner wall of the collecting hood, a sloped rod is fixedly connected to the bottom of the spring plate, an air blowing pipe is connected through the side wall of the collecting hood, a water inlet pipe is fixedly connected to the bottom of the spring plate, and a one-way valve 1 is fixedly connected to the inner wall of the water inlet pipe; Among them, a water outlet pipe is connected through the side wall of the collecting hood, and a one-way valve 2 is fixedly connected to the inner wall of the water outlet pipe. A sewage discharge plate is rotatably connected to the inner wall of the collecting hood. By utilizing the force of the scraper moving, when the scraper pushes impurities into the collecting hood, the right side of the scraper will contact the inclined rod. Since the contact surfaces of the scraper and the inclined rod are both inclined, the scraper will smoothly push the inclined rod up, drive the spring plate to rise, and accumulate rebound force. When the spring plate rises, it will squeeze the gas in the collecting hood and spray it out through the air pipe to disperse the impurities on the water surface, increase its contact area with the water body, and promote the sedimentation process.

[0011] A method for using a liquid-carrying measurement and calibration device for an external floating roof vertical metal tank comprises the following steps: S1: Start the motor to drive the connecting frame to rotate, so that the fixed drum rotates around the drum screen. When the fixed drum moves, it drives the screw rod to rotate, so that the gear meshes with the gear ring, and the gear revolves, thereby causing the screw rod to revolve; S2: When the spiral rod revolves, it will contact the outer wall of the drum screen. When the spiral rod contacts leaves or plastic garbage, the sawtooth blocks on the outer wall of the spiral rod will crush the leaves and hook the plastic garbage. The plastic garbage will be separated from the drum screen due to the revolution of the spiral rod. S3: As the spiral rod rotates, the plastic waste will come into contact with the wall of the fixed cylinder, causing the plastic waste to be squeezed. As the spiral rod rotates, the plastic waste will be affected by friction, thus breaking the plastic waste.

[0012] The present invention has the following beneficial effects: (1) When the present invention is used, the staff installs the metering calibrator at the bottom of the floating roof to calibrate and measure the liquid stored in the metal tank. When encountering heavy rainfall, rainwater will slide down from the top of the floating roof and gather at the center of the floating roof. The rainwater will be discharged through the drain pipe. The rainwater will pass through the drum screen during the sliding process. The drum screen will block the leaves or plastic garbage carried by the rainwater. Then the motor is started to drive the connecting frame to rotate, so that the fixed drum rotates around the drum screen. When the fixed drum moves, it will drive the spiral rod to rotate, so that the gear and the gear ring are meshed, and the gear revolves, thereby causing the spiral rod to revolve. When the spiral rod revolves, it will contact the outer wall of the drum screen. When the spiral rod contacts the leaves or plastic garbage, since the outer wall of the spiral rod has a sawtooth block, the sawtooth block will crush the leaves and hook the plastic garbage. The plastic garbage will be separated from the drum screen due to the revolution of the spiral rod. As the spiral rod rotates, the plastic garbage will contact the drum wall of the fixed drum, causing the plastic garbage to be affected. The plastic waste will be squeezed, and the friction will affect the plastic waste as it rotates, thus breaking the plastic waste. The broken plastic waste will be driven by the screw to rise to the top of the screw. When the screw revolves, the screw drives the pushing block to rotate through the slider. When the pushing block contacts the broken waste, the pushing block will push the waste to move to the collecting plate. As the pushing block continues to rotate, the pushing block will contact the convex block of the collecting plate. Since the contact surfaces of the pushing block and the collecting plate are both inclined surfaces, the pushing block will rise to separate the waste from the pushing block, so that the waste falls on the collecting plate and is collected. This cleans and collects waste in rainwater, prevents leaves and plastic waste from blocking the holes of the drum screen on a large scale, ensures that rainwater can be discharged stably, and avoids rainwater accumulating on the floating roof, which leads to an increase in the weight of the floating roof. This ensures that the pressure in the metal tank is stable, so that the metering calibrator can accurately measure the liquid content in the metal tank.

[0013] (2) The present invention utilizes the force of the connection frame moving. When the connection frame rotates, it will also drive the connection shells 1 and 2 to rotate around the drum screen, drive the spring piston plate to move, and make the spring piston plate contact with the bottom of the concave-convex ring. Since the concave-convex ring is wavy, when the spring piston plate moves to the convex position of the concave-convex ring, it will be squeezed and move downward while accumulating rebound force, driving the sliding rod to move, causing the sliding plate to descend. When the spring piston plate descends, it will squeeze the rainwater entering the connection shell 1 and spray it out through the nozzle on the water spray plate, hitting the holes of the drum screen. The holes are sprayed out. When the spring piston plate moves to the concave position of the concave-convex ring, the rebound force of the spring piston plate will be released, causing the spring piston plate to rise, driving the sliding plate to rise, and so on. The sliding plate will drive the rolling roller to move back and forth, rubbing the broken leaves to break them again, and coordinating with the rainwater sprayed by the water spray plate to separate the leaves from the outer wall and holes of the drum screen, preventing the broken leaves from adhering to the outer wall and holes of the drum screen, thereby ensuring the continuity of rainwater flow, reducing water flow resistance and quickly draining water.

[0014] (3) The present invention utilizes the force of the movement of the second connecting shell. When the second connecting shell rotates around the drum screen, it drives the roller to move. When the roller contacts the drum screen, the friction between the roller and the drum screen causes the roller to revolve. The impurities floating on the outer wall of the drum screen are sprayed out by the water spray plate. As the rainwater in the water spray plate is sprayed out, the impurities move to the two sides of the sliding plate. Some impurities enter the collecting trough. The baffle plate and the fitting plate block the rainwater to prevent the rainwater from entering the second connecting shell. As the roller rotates, the spring reset plate is driven to rotate, causing the impurities to enter the second connecting shell. Since the spring reset plate is previously in a compressed state, when the spring reset plate enters the second connecting shell, the obstruction to the spring reset plate disappears. At this time, the rebound force of the spring reset plate is released, pushing the rainwater carrying impurities into the second connecting shell, such as: Figure 8 As shown on the right, as the drum rotates, the returned spring reset plate will contact the inclined surface of the collecting groove, so that the spring reset plate is squeezed and compressed again. The impurities are collected into the connecting shell 2 in this reciprocating manner. When the sliding plate descends, it will slide inside the rotating frame, causing the rotating frame to rotate and tilt, pushing the scraper to move, pushing the impurities that enter the connecting shell 2 into the collecting cover, preventing the deposition of impurities caused by excessive rainfall, thereby reducing the difficulty and frequency of subsequent cleaning and ensuring that drainage can remain smooth for a long time.

[0015] (4) The present invention utilizes the force of the scraper moving. When the scraper pushes the impurities into the collection cover, the right side of the scraper will contact the inclined rod. Since the contact surfaces of the scraper and the inclined rod are both inclined, the scraper will smoothly push the inclined rod up, driving the spring plate to rise, accumulating rebound force. When the spring plate rises, it will squeeze the gas in the collection cover and spray it out through the blowing pipe to disperse the impurities on the water surface, increase its contact area with the water body, and promote the sedimentation process. At the same time, when the spring plate rises, it will make the bottom of the spring plate, such as: Fig. 9 As shown, suction is generated to suck the rainwater collected and precipitated in the collection cover into the bottom of the spring plate through the water inlet pipe. When the scraper is separated from the inclined rod, the resilience of the spring plate will be released to squeeze the rainwater at the bottom of the spring plate. Since one-way valve 1 is installed in the water inlet pipe and one-way valve 2 is installed in the water outlet pipe to prevent rainwater from flowing back, the rainwater will be discharged smoothly from the water outlet pipe, and this reciprocating process will cause impurities to settle at the bottom of the collection cover, preventing the connecting shell 2 and the collection cover from being filled with rainwater, thereby ensuring the stable collection of impurities, ensuring the timely treatment and discharge of impurities during rainfall, and achieving a good anti-fouling effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in 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.

[0020] For example, see Figure 1 - Figure 5 The present invention is a liquid-carrying measurement and calibration device for a vertical metal tank with an external floating roof, comprising a drainage mechanism 1, wherein the drainage mechanism 1 further comprises a metal tank 101, wherein a floating roof 102 is slidably connected to the inner wall of the metal tank 101, a fixed column 103 is fixedly connected to the top of the floating roof 102, and a connecting frame 104 is rotatably connected to the inner wall of the fixed column 103; Crushing mechanism 2, the crushing mechanism 2 comprises three connecting shells 1 201 fixedly connected to the side wall of the connecting frame 104, three connecting shells 202 fixedly connected to the side wall of the connecting frame 104, spring piston plates 204 are slidably connected to the inner walls of the three connecting shells 1 201, and the parts contained in the three connecting shells 1 201 are the same, and the parts contained in the three connecting shells 202 are the same; The collecting mechanism 3 includes two rollers 301 rotatably connected to the inner wall of the connecting shell 202, and four bonding plates 302 are fixedly connected to the inner wall of the connecting shell 202. The four bonding plates 302 are grouped in pairs, and the side walls of the two groups of bonding plates 302 are fixedly connected with fixing rings 303.

[0021] The drainage mechanism 1 further includes a motor 105 fixedly connected to the inner wall of the fixed column 103, the top output end of the motor 105 is fixedly connected to the bottom of the connecting frame 104, a drum screen 106 is fixedly connected to the top of the floating roof 102, a metering calibrator 107 is fixedly connected to the bottom of the floating roof 102, and three drainage pipes 108 are connected through the inner wall of the floating roof 102; Among them, a connecting ring 109 is fixedly connected to the outer wall of the fixed column 103, a gear ring 110 is fixedly connected to the outer wall of the connecting ring 109, and three fixed cylinders 111 are fixedly connected to the side wall of the connecting frame 104. The three fixed cylinders 111 contain the same parts. When encountering heavy rainfall, rainwater will slide down from the top of the floating roof 102 and gather at the center of the floating roof 102. The rainwater is discharged through the drain pipe 108. The rainwater will pass through the drum screen 106 during the sliding process. The drum screen will block the leaves or plastic garbage carried by the rainwater, and then start the motor 105 to drive the connecting frame 104 to rotate, so that the fixed cylinder 111 rotates around the drum screen 106.

[0022] The drainage mechanism 1 also includes a spiral rod 112 rotatably connected to the inner wall of the fixed cylinder 111, a gear 113 is fixedly connected to the top of the spiral rod 112, the outer wall of the gear 113 is meshed with the inner wall of the gear ring 110, a protective door 114 is rotatably connected to the outer wall of the fixed cylinder 111, a push block 115 is slidably connected to the outer wall of the spiral rod 112, and a collection plate 116 is fixedly connected to the inner wall of the fixed cylinder 111. When the fixed cylinder 111 moves, the spiral rod 112 is driven to rotate, so that the gear 113 is meshed with the gear ring 110. , so that the gear 113 revolves, thereby making the screw rod 112 revolve. When the screw rod 112 revolves, it will contact the outer wall of the drum screen 106. When the screw rod 112 contacts leaves or plastic waste, since the outer wall of the screw rod 112 has sawtooth blocks, the sawtooth blocks will crush the leaves and hook the plastic waste. The plastic waste will be separated from the drum screen 106 due to the revolution of the screw rod 112. As the screw rod 112 rotates, the plastic waste will contact the wall of the fixed drum 111, so that the plastic waste is squeezed. The plastic waste will be affected by the friction force, so that the plastic waste will be broken. The broken plastic waste will be driven by the spiral rod 112 to spirally rise to the top of the spiral rod 112. When the spiral rod 112 revolves, the spiral rod 112 drives the push block 115 to rotate through the slider. When the push block 115 contacts the broken waste, the push block 115 will push the waste to move to the collection plate 116. As the push block 115 continues to rotate, the push block 115 will contact the convex block of the collection plate 116. The contact surfaces are all inclined surfaces, so the push block 115 will rise to separate the garbage from the push block 115, causing the garbage to fall onto the collection plate 116 and collect the garbage, thereby cleaning and collecting the garbage in the rainwater, preventing leaves and plastic garbage from blocking the holes of the drum screen 106 on a large scale, ensuring that rainwater can be discharged stably, and avoiding rainwater accumulation on the floating roof 102, which causes the weight of the floating roof 102 to increase, thereby ensuring the pressure in the metal tank 101 is stable, allowing the measurement calibrator 107 to accurately measure the liquid content in the metal tank 101.

[0023] For example 2, please refer to Figure 6 - Fig.10The present invention is a liquid-carrying metering and calibration device for a vertical metal tank with an external floating roof. On the basis of the first embodiment, the crushing mechanism 2 also includes a concave-convex ring 203 fixedly connected to the bottom of the connecting ring 109, a water spray plate 205 is fixedly connected to the inner wall of the connecting shell 1 201, the top of the spring piston plate 204 is slidably connected to the bottom of the concave-convex ring 203, and a sliding rod 206 is fixedly connected to the outer wall of the spring piston plate 204. By utilizing the force of the movement of the connecting frame 104, when the connecting frame 104 rotates, it will also drive the connecting shell 1 201 and the connecting shell 2 202 to rotate around the drum screen 106, drive the spring piston plate 204 to move, and make the spring piston plate 204 contact with the bottom of the concave-convex ring 203. Since the concave-convex ring 203 is wavy, when the spring piston plate 204 moves to the convex position of the concave-convex ring 203, it will be squeezed and move downward while accumulating rebound force, driving the sliding rod 206 to move.

[0024] The crushing mechanism 2 also includes a baffle 208 fixedly connected to the inner wall of the connecting shell 202, a sliding plate 207 is slidably connected to the inner wall of the baffle 208, seven rolling rollers 209 are rotatably connected to the inner wall of the sliding plate 207, the top of the sliding plate 207 is fixedly connected to the bottom of the sliding rod 206, and six nozzles are fixedly connected to the inner wall of the water spray plate 205. When the sliding plate 207 is lowered, when the spring piston plate 204 is lowered, the rainwater entering the connecting shell 1 201 will be squeezed and sprayed out through the nozzles on the water spray plate 205, and sprayed out to the holes of the drum screen 106. 04 moves to the concave position of the concave-convex ring 203, the rebound force of the spring piston plate 204 will be released, causing the spring piston plate 204 to rise, driving the sliding plate 207 to rise, and so on to make the sliding plate 207 move back and forth. The sliding plate 207 will drive the rolling roller 209 to move back and forth, rubbing the broken leaves to break them again, and cooperating with the rainwater sprayed by the water spray plate 205 to separate the leaves from the outer wall and holes of the drum screen 106, preventing the broken leaves from adhering to the outer wall and holes of the drum screen 106, thereby ensuring the continuity of rainwater flow, reducing water flow resistance and quickly draining water.

[0025] The collecting mechanism 3 also includes five collecting grooves 305 provided on the inner wall of the drum 301, the inner walls of the five collecting grooves 305 are all slidably connected with spring return plates 304, the bottom of the inner wall of the connecting shell 202 is slidably connected with a scraper 306, and the top of the scraper 306 is slidably connected with a rotating frame 307; Among them, the outer wall of the rotating frame 307 is slidably connected to the inner wall of the connecting shell 202, the side wall of the sliding plate 207 is slidably connected to the inner wall of the rotating frame 307, and the outer wall of the fixed ring 303 is rotatably connected to the inner wall of the drum 301. By utilizing the force of the movement of the connecting shell 202, when the connecting shell 202 rotates around the drum screen 106, the drum 301 will be driven to move. When the drum 301 and the drum screen 106 are in contact, the friction between the drum 301 and the drum screen 106 causes the drum 301 to revolve. The impurities floating on the outer wall of the drum screen 106 are sprayed out by the water spray plate 205. As the rainwater in the water spray plate 205 is sprayed out, the impurities will move to both sides of the sliding plate 207, and some impurities will enter the collecting trough 305. The baffle 208 and the bonding plate 302 will block the rainwater to prevent it from entering the connecting shell 202.

[0026] The collecting mechanism 3 further comprises a collecting cover 308 fixedly connected to the outer wall of the connecting shell 202, a spring plate 309 is slidably connected to the inner wall of the collecting cover 308, a sloped rod 310 is fixedly connected to the bottom of the spring plate 309, an air blowing pipe 311 is connected through the side wall of the collecting cover 308, a water inlet pipe 312 is fixedly connected to the bottom of the spring plate 309, and a one-way valve 1 is fixedly connected to the inner wall of the water inlet pipe 312; Among them, a water outlet pipe 313 is connected to the side wall of the collecting hood 308, and a one-way valve 2 is fixedly connected to the inner wall of the water outlet pipe 313. A sewage discharge plate 314 is rotatably connected to the inner wall of the collecting hood 308. By utilizing the moving force of the scraper 306, when the scraper 306 pushes the impurities into the collecting hood 308, the right side of the scraper 306 will contact the inclined rod 310. Since the contact surfaces of the scraper 306 and the inclined rod 310 are both inclined surfaces, the scraper 306 will smoothly push the inclined rod 310 to rise, drive the spring plate 309 to rise, and accumulate rebound force. When the spring plate 309 rises, it will squeeze the gas in the collecting hood 308 and spray it out through the blowing pipe 311, so as to disperse the impurities on the water surface, increase its contact area with the water body, and promote the sedimentation process.

[0027] The method for using the external floating roof vertical metal tank liquid metering calibration device includes the following steps: S1: Start the motor 105 to drive the connecting frame 104 to rotate, so that the fixed cylinder 111 rotates around the drum screen 106. When the fixed cylinder 111 moves, it drives the screw rod 112 to rotate, so that the gear 113 is meshed with the gear ring 110, so that the gear 113 revolves, thereby causing the screw rod 112 to revolve; S2: When the screw rod 112 revolves, it will contact the outer wall of the drum screen 106. When the screw rod 112 contacts leaves or plastic waste, the sawtooth blocks on the outer wall of the screw rod 112 will crush the leaves and hook the plastic waste. The plastic waste will be separated from the drum screen 106 due to the revolution of the screw rod 112. S3: As the spiral rod 112 rotates, the plastic waste will contact the wall of the fixed cylinder 111, so that the plastic waste is squeezed. As the spiral rod 112 rotates, the plastic waste is affected by friction, so that the plastic waste is broken.

[0028] A specific application of this embodiment is: when the present invention is used, the staff installs the metering calibrator 107 at the bottom of the floating roof 102 to calibrate and measure the liquid stored in the metal tank 101. When encountering heavy rain weather, rainwater will slide down from the top of the floating roof 102 and gather at the center of the floating roof 102. The rainwater is discharged through the drain pipe 108. The rainwater will pass through the drum screen 106 during the sliding process. The drum screen will block the leaves or plastic garbage carried by the rainwater. Then, the motor 105 is started to drive the connecting frame 104 to rotate, so that the fixed drum 111 rotates around the drum screen 106, and the fixed drum 111 rotates around the drum screen 106. When the cylinder 111 moves, it drives the screw rod 112 to rotate, so that the gear 113 is meshed with the gear ring 110, and the gear 113 is allowed to revolve, thereby causing the screw rod 112 to revolve. When the screw rod 112 revolves, it will contact the outer wall of the cylinder screen 106. When the screw rod 112 contacts leaves or plastic waste, since the outer wall of the screw rod 112 has sawtooth blocks, the sawtooth blocks will break the leaves and hook the plastic waste. The plastic waste will be separated from the cylinder screen 106 due to the revolution of the screw rod 112. As the screw rod 112 rotates, the plastic waste will contact the cylinder wall of the fixed cylinder 111. The plastic waste is squeezed by the screw rod 112, and the plastic waste is affected by the friction force due to the rotation of the screw rod 112, so that the plastic waste is broken. The broken plastic waste is driven by the screw rod 112 to spirally rise to the top of the screw rod 112. When the screw rod 112 revolves, the screw rod 112 drives the push block 115 to rotate through the slider. When the push block 115 contacts the broken waste, the push block 115 pushes the waste to move to the collection plate 116. As the push block 115 continues to rotate, the push block 115 contacts the convex block of the collection plate 116. The contact surfaces of the block 115 and the collecting plate 116 are both inclined surfaces, so the push block 115 will rise to separate the garbage from the push block 115, so that the garbage falls on the collecting plate 116, and the garbage is collected, so as to clean and collect the garbage in the rainwater, and prevent leaves and plastic garbage from blocking the holes of the drum screen 106 on a large scale, so as to ensure that the rainwater can be discharged stably, and avoid rainwater accumulation on the floating roof 102, which causes the weight of the floating roof 102 to increase, thereby ensuring the pressure in the metal tank 101 to be stable, so that the measurement calibrator 107 can accurately measure the liquid content in the metal tank 101; Secondly, when the connecting frame 104 rotates, it will also drive the connecting shell 1 201 and the connecting shell 202 to rotate around the drum screen 106, driving the spring piston plate 204 to move, so that the spring piston plate 204 contacts the bottom of the concave-convex ring 203. Since the concave-convex ring 203 is wavy, when the spring piston plate 204 moves to the raised position of the concave-convex ring 203, it will be squeezed and move downward while accumulating rebound force, driving the sliding rod 206 to move, so that the sliding plate 207 descends. When the spring piston plate 204 descends, it will squeeze the rainwater entering the connecting shell 1 201 and spray it out through the nozzle on the water spray plate 205, which will affect the drum screen 106. The holes are sprayed out. When the spring piston plate 204 moves to the concave position of the concave-convex ring 203, the rebound force of the spring piston plate 204 will be released, so that the spring piston plate 204 rises, driving the sliding plate 207 to rise, and the sliding plate 207 moves back and forth in this way. The sliding plate 207 will drive the rolling roller 209 to move back and forth, rubbing the broken leaves to break them again, and the rainwater sprayed by the water spraying plate 205 separates the leaves from the outer wall and holes of the drum screen 106, so as to prevent the broken leaves from adhering to the outer wall and holes of the drum screen 106, thereby ensuring the continuity of rainwater flow, reducing water flow resistance and draining water quickly; Secondly, when the connecting shell 202 rotates around the drum screen 106, it drives the roller 301 to move. When the roller 301 and the drum screen 106 are in contact, the friction between the roller 301 and the drum screen 106 causes the roller 301 to revolve, and the impurities floating on the outer wall of the drum screen 106 are sprayed out by the water spray plate 205. As the rainwater in the water spray plate 205 is sprayed out, the impurities will move to the two sides of the sliding plate 207, and some impurities will enter the collecting tank 305. The water is blocked to prevent rainwater from entering the second connection shell 202. As the roller 301 rotates, the spring reset plate 304 is driven to rotate, which will cause impurities to enter the second connection shell 202. Since the spring reset plate 304 is previously in a compressed state, when the spring reset plate 304 enters the second connection shell 202, the blocking of the spring reset plate 304 disappears. At this time, the rebound force of the spring reset plate 304 will be released, pushing the rainwater carrying impurities into the second connection shell 202, such as: Figure 8 As shown on the right side, as the roller 301 rotates, the returned spring reset plate 304 will contact the inclined surface of the collecting groove 305, so that the spring reset plate 304 is squeezed and is in a compressed state again, and the impurities are collected into the connecting shell 202 in this way. When the sliding plate 207 descends, it will slide inside the rotating frame 307, so that the rotating frame 307 rotates and tilts, pushing the scraper 306 to move, and pushing the impurities entering the connecting shell 202 into the collecting cover 308, so as to prevent the impurities from being deposited due to excessive rainfall time, thereby reducing the difficulty and frequency of subsequent cleaning, and ensuring that the drainage can remain smooth for a long time; Secondly, when the scraper 306 pushes the impurities into the collection cover 308, the right side of the scraper 306 will contact the inclined rod 310. Since the contact surfaces of the scraper 306 and the inclined rod 310 are both inclined, the scraper 306 will smoothly push the inclined rod 310 to rise, driving the spring plate 309 to rise, accumulating the rebound force, and when the spring plate 309 rises, it will squeeze the gas in the collection cover 308 and spray it through the blowing pipe 311 to disperse the impurities on the water surface, increase its contact area with the water body, and promote the sedimentation process. At the same time, when the spring plate 309 rises, it will make the bottom of the spring plate 309, such as: Fig. 9 As shown, suction is generated to suck rainwater collected and precipitated in the collection cover 308 to the bottom of the spring plate 309 through the water inlet pipe 312. When the scraper 306 is separated from the inclined rod 310, the resilience of the spring plate 309 will be released, squeezing the rainwater at the bottom of the spring plate 309. Since a one-way valve 1 is installed in the water inlet pipe 312 and a one-way valve 2 is installed in the water outlet pipe 313, rainwater backflow is prevented, so rainwater is smoothly discharged from the water outlet pipe 313. This reciprocating process causes impurities to settle at the bottom of the collection cover 308, preventing the connection shell 202 and the collection cover 308 from being filled with rainwater, ensuring the stable collection of impurities, ensuring the timely treatment and discharge of impurities during rainfall, and achieving a good anti-fouling effect. Among them, when the rain stops, the staff can open the push block 115 and the protective door 114 to clean the impurities collected in the collection plate 116 and the collection cover 308, so that the above components can operate stably.
