Description

Technical Field

[0001] The invention relates to the technical field of liquid degassing, in particular to a rotary degassing device. Background Art

[0002] As we all know, when the ship's power equipment is in reverse, or in strong winds and waves, a large number of bubbles are sucked into the sea chest by the system's pump. As an important part of the seawater system, the exhaust performance of the sea chest directly affects the performance of the seawater system.

[0003] At present, the widely used exhaust method is to exhaust through the breather pipe, breather check valve and breather pipe elbow installed on the top of the sea valve box. However, the exhaust effect of this exhaust method is poor, so that a large number of bubbles are sucked into the system water pump; the system water pump cannot suck up water instantly, which causes the temperature of the seawater system to rise suddenly, and the user equipment such as the main engine, steering gear, fin stabilizer, air conditioning unit, radar, etc. will automatically shut down. The shutdown of these equipment is a fatal blow to the execution of missions at sea and the comfort of the crew.

[0004] Secondly, the height of the vent pipe elbow of the sea chest is usually not less than two meters from the ship's bottom baseline BL. After long-term operation, it was found that when the power equipment is reversed or in strong winds and waves, a large amount of seawater with bubbles will splash out of the vent pipe elbow, increasing the insecurity of the ship and personnel, polluting the environment around the vent pipe elbow, and adding maintenance workload for the crew.

[0005] Thirdly, the presence of a large amount of gas in the pipeline will cause cavitation and pipeline "water hammer" phenomenon on the inner wall of the pipeline and the inner wall of the user's equipment, seriously endangering the safe use of the pipeline system and user equipment, and causing harsh internal noise in the pipeline.

[0006] Therefore, it is necessary to provide a rotary degassing device to remove a large amount of gas in the seawater system in a timely manner. Summary of the invention

[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rotary degassing device for solving the problems of large amount of gas in the seawater system causing shutdown of user equipment, environmental pollution, pipeline and user equipment safety and noise in the prior art.

[0008] To achieve the above-mentioned purpose and other related purposes, the present invention provides a rotary degassing device, which has the following beneficial effects: the rotary degassing device is electrically connected to a connecting unit, a rotary degassing unit, a drainage unit and a control structure through a control unit, remotely displays the operating status and comprehensive fault alarm signal of the rotary degassing device, and performs remote control to realize intelligent and fully automatic operation functions, improve degassing efficiency and save labor costs; the rotary degassing device, through the control unit, can enable the water pump to be linked with user equipment and meteorological and hydrological observation equipment, automatically identify the status of the ship or the wind and wave conditions on the sea surface, and automatically adjust the degassing function and the bypass function, thereby automatically protecting the user equipment and saving energy.

[0009] The rotating motor drives the degassing water tank or the water injection pipe to rotate, and cooperates with the swing motor to make the degassing water tank swing as a whole, or cooperates with the rotating motor to drive the dehydration water tank to rotate as a whole, so as to remove the gas that affects the operation of the user system and damages the equipment and pipelines, and effectively prevents the gas in the water from entering the water pump and causing the user's equipment to shut down, providing a guarantee for the high-performance operation of the user's equipment and ensuring the safety of navigation; the air release valve only allows gas to escape, avoiding the air vent from splashing out of the seawater with bubbles to pollute the environment inside the ship, and eliminating the maintenance work of the crew; it also avoids cavitation and pipeline "water hammer" phenomenon on the inner wall of the pipeline and the inner wall of the user's equipment, protects the safety of the use of the pipeline system and the user's equipment, and greatly reduces the economic cost and the noise inside the pipeline; it can be used for degassing of seawater systems and freshwater systems, and can be used for ships and land buildings, with strong applicability and a wide range of applications.

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0072] For example, when describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0073] For convenience of description, spatially relative terms such as "under", "below", "below", "below", "above", "on", etc. may be used herein to describe the relationship of one element or feature shown in the drawings to other elements or features. It will be understood that these spatially relative terms are intended to encompass other orientations of the device in use or operation in addition to the orientation depicted in the drawings.

[0074] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0075] like Figure 1 As shown, the present invention provides a rotary degassing device, which at least comprises:

[0076] The connection unit includes a water inlet electric valve 120, a water delivery electric valve 130, and a booster pump 140. The water inlet electric valve 120 is connected to the water inlet pipe 110, and the water delivery electric valve 130 and the booster pump 140 are connected to the water delivery pipe 150 at intervals.

[0077] The rotary degassing unit comprises a degassing water tank 210, a rotary motor 220, a water injection pipe 230 and a water extraction pipe 240. A venting valve 211 is provided on the top of the degassing water tank 210. The rotary motor 220 is fixed to the outer wall of the degassing water tank 210. The water injection pipe 230 is located inside the degassing water tank 210 and passes through the degassing water tank 210 to communicate with the water inlet pipe 110. The water extraction pipe 240 is located inside the degassing water tank 210 and passes through the degassing water tank 210 to communicate with the water delivery pipe 150.

[0078] The cache unit includes a cache water tank 300, wherein the cache water tank 300 is connected to the water pumping pipe 240 through a water delivery pipe 150;

[0079] A drainage unit, including a water pump 410, one end of which is connected to the cache unit and the other end of which is connected to the user equipment through a drainage pipe 430;

[0080] A control unit 600 is electrically connected to the connection unit, the rotary degassing unit and the drainage unit.

[0081] Specifically, if used for degassing of seawater system, the present invention can be installed in a large cabin at the bottom of the ship close to the sea box and the seawater filter, such as the engine room. When the power equipment such as the propeller is in reverse, or in the case of strong wind and waves, the seawater needs to be degassed before it is provided to the target user. The water inlet pipe 110 is the seawater pipe that needs to be degassed after the sea box and the seawater filter; when the power equipment such as the propeller is sailing forward normally, or when the sea surface is calm, the seawater can be directly supplied to the user equipment without degassing. The seawater pipe that does not need to be degassed after the sea box and the seawater filter is directly connected to the drainage unit through the bypass pipe 160, wherein the bypass pipe 160 is closer to the sea box and the seawater filter than the water inlet pipe 110. If used for degassing of fresh water system, the present invention can be installed in any cabin of a ship or any suitable position on land, and the water inlet pipe 110 is any fresh water pipe that needs to be degassed.

[0082] The water pipe 150 is used to transport the airless water that has been degassed in the rotary degassing unit to the buffer unit, or the water pipe 150 is used to transport the water that has been degassed in one rotary degassing unit to the next rotary degassing unit for further degassing, so as to realize setting up multiple rotary degassing units for multiple degassing operations. At this time, the water pipe is also the water inlet pipe of the next rotary degassing unit. The rotary degassing units can be arranged multiple times as the same rotary degassing units, or can be arranged in sequence as multiple different rotary degassing units. The specific setting is based on the actual degassing requirements, and there is no strict restriction here. The booster pump 140 connected to the water pipe 150 provides power for water delivery, such as Figure 1 As shown. In this embodiment, the cache unit is a cache water tank 300, which temporarily stores the treated degassed water to facilitate the continuous delivery of degassed water to user equipment; the booster pump 140 is a small silent booster pump, which is different from the traditional system pump (horizontal or vertical water pump). It is only the size of a palm, with the inlet and outlet at both ends, and a water-cooled shielded structure, which runs more quietly. Due to its small size, light weight, small space, and large pressure head, it can be completely installed on the water pipe as a pipe accessory.

[0083] In order to control water inlet and water delivery, a water inlet electric valve 120 is connected to the water inlet pipe 110, a water delivery electric valve 130 is connected to the water delivery pipe 150, and a bypass electric valve 170 is connected to the bypass pipe 160. In one embodiment, the water inlet electric valve 120, the water delivery electric valve 130 and the bypass electric valve 170 are all electric stop valves with opening, closing and flow gear adjustment functions. The water inlet electric valve 120, the water delivery electric valve 130 and the bypass electric valve 170 receive the opening, closing or flow gear adjustment instructions of the control unit 600 through the electric valve control signal line, and transmit their operating status electric valve status signal line to the control unit 600; the booster pump 140 receives the opening and closing instructions of the control unit 600 through the booster pump control signal line, and transmits its operating status to the control unit 600 through the booster pump status signal line.

[0084] The drainage unit includes a pump 410, which pumps out the airless water in the buffer unit and supplies it to the user device through a drain pipe 430. Preferably, the drainage unit also includes an electric stop check valve 420 for regulating the water flow level and preventing water backflow. The pump 410 receives the opening and closing instructions of the control unit 600 through the pump control signal line, and transmits its operating status to the control unit 600 through the pump status signal line; the electric stop check valve 420 receives the opening, closing or flow level adjustment instructions of the control unit 600 through the electric stop check valve control signal line, and transmits its operating status to the control unit 600 through the electric stop check valve status signal line.

[0085] The rotary degassing unit includes a first rotary degassing unit S1, a second rotary degassing unit S2 and a third rotary degassing unit S3, which have different degassing methods and can be used in combination as needed for precision equipment with higher water quality requirements; of course, the user can also only set up any one of the three embodiments of the present invention to provide a degassed water source according to the size of the space and the needs of the target user's equipment.

[0086] It is described in detail below in the form of embodiments.

[0087] Example 1

[0088] The first rotary degassing unit S1 includes a first motor 250, a connecting rod 260, a degassing water tank 210, a rotating motor 220, a water injection pipe 230 and a water extraction pipe 240. The top of the first motor 250 is installed on a corresponding support surface above the degassing water tank 210, such as a ceiling, a deck or the top of a box shell, through a movable joint; one end of the connecting rod 260 is connected to the first motor 250, and the other end is connected to the rotating motor 220, wherein the rotating motor 220 is fixed on the top of the degassing water tank 210, and can drive the degassing water tank 210 to rotate 360° in a circle. In one embodiment, the first motor 250 is a swing motor, which drives the connecting rod 260 and the degassing water tank 210 to swing left and right at a certain angle, such as Figure 2 As shown. In other embodiments, the activity space is large enough, and the first motor 250 is a rotating motor, which drives the connecting rod 260 and the degassing water tank 210 to form a conical revolution around it. During the rotation and shaking of the degassing water tank 210, the water inside the degassing water tank 210 continuously hits the inner wall of the tank, and the gas in the water is precipitated and escapes through the air release valve 211 on the top of the degassing water tank 210. The air release valve 211 can allow the gas released from the internal water to escape in time, and the water will not overflow, thereby avoiding environmental pollution.

[0089] The water injection pipe 230 and the water extraction pipe 240 are located inside the degassing water tank 210, penetrate the top of the degassing water tank 210, and are connected to the water inlet pipe 110 and the water delivery pipe 150 that pass through the first motor 250, the connecting rod 260 and the rotating motor 220. The water injection pipe 230 is connected to the water inlet pipe 110 to inject water into the degassing water tank 210. Preferably, a nozzle 231 is connected to the end of the water injection pipe 230 to expand the water injection from a point to a surface, reduce the impact of the water column on the bottom of the water tank during water injection, and effectively protect the safety and service life of the water tank. The water extraction pipe 240 is connected to the water delivery pipe 150 to transport the degassed water to the cache unit or the next rotating degassing unit.

[0090] The first motor 250 receives the start / stop command of the control unit 600 through the first motor control signal line, and transmits its operating status to the control unit 600 through the first motor status signal line; the rotating motor 220 receives the start / stop command of the control unit 600 through the rotating motor control signal line, and transmits its operating status to the control unit 600 through the rotating motor status signal line.

[0091] Example 2

[0092] The second rotary degassing unit S2 includes a telescopic component, a second rotary component, a connecting structure 270, a degassing water tank 210, a rotary motor 220, a water injection pipe 230 and a water extraction pipe 240. The same parts as those in Example 1 are not repeated here. A vent valve 211 is provided on the top of the degassing water tank 210. In order to facilitate the rotation of the degassing water tank 210, the vent valve 211 is located in the concave part of the degassing water tank 210. The degassing water tank 210 rotates 360° in a circle under the action of the rotary motor 220. In order to ensure the stability of the rotation, the rotary motor 220 is arranged at the end of the center line 212 of the degassing water tank. It can be arranged at only one end or at both ends at the same time, and it is arranged according to actual needs. For a non-circular degassing water tank, the center line 212 of the degassing water tank refers to the line connecting the center of the top and the center of the bottom of the degassing water tank; for a circular degassing water tank, the end where the air release valve 211 is located is the top, and the center line 212 of the degassing water tank is the line connecting the two ends of any circle center on the degassing water tank 210 near the air release valve 211. The connecting structure 270 is located outside the degassing water tank 210 and is at a suitable distance from the degassing water tank 210 to facilitate the rotation of the degassing water tank 210. It connects the two ends of the center line 212 of the degassing water tank and is symmetrical about the center line 212 of the degassing water tank. In one embodiment, as Figure 1 The degassing water tank 210 is circular, and the rotating motor 220 is located at both ends of the degassing water tank centerline 212. The connecting structure 270 is a circular connecting ring that is concentric with the degassing water tank 210 and has a larger radius, connecting the top rotating motor 220 and the bottom rotating motor 220.

[0093] When a rotating motor is provided on the top of the deaerated water tank 210, the water injection pipe 230 penetrates the top of the deaerated water tank 210 and the rotating motor 220 to communicate with the water inlet pipe 110, and the water extraction pipe 240 penetrates the top of the deaerated water tank 210 and the rotating motor 220 to communicate with the water delivery pipe 150; when a rotating motor is not provided on the top of the deaerated water tank 210, the water injection pipe 230 penetrates the top of the deaerated water tank 210 and the connecting structure 270 to communicate with the water inlet pipe 110, and the water extraction pipe 240 penetrates the top of the deaerated water tank 210 and the connecting structure 270 to communicate with the water delivery pipe 150. Since the water injection pipe 230 and the water inlet pipe 110, and the water extraction pipe 240 and the water delivery pipe 150 are disconnected when the deaerated water tank 210 is dehydrated, the water injection pipe 230 is connected to the water inlet pipe 110 when injecting water, and the water extraction pipe 240 is connected to the water delivery pipe 150 when extracting water. Therefore, two sets of telescopic components are provided, each set of telescopic components includes a telescopic motor 291, a telescopic rod 292 and a telescopic hose (not shown) passing through the telescopic motor 291 and the telescopic rod 292, one telescopic hose connects the water inlet pipe 110 and the water injection pipe 230, and the other telescopic hose connects the water extraction pipe 240 and the water delivery pipe 150. Figure 3The connecting ends of the telescopic hose, the water injection pipe 230 and the water extraction pipe 240 are all provided with quick self-locking joints (not shown) so as to achieve connection and disconnection under the drive of the telescopic motor 291 and the telescopic rod 292. In one embodiment, the telescopic rod 292 is a two-section telescopic rod, and a telescopic rod with more than two sections can also be used according to actual needs, which is not strictly limited here.

[0094] Under the premise that the deaerated water tank 210 rotates 360° in a circle under the action of the rotating motor 220, the second rotating assembly includes a second rotating motor 281, a second connecting structure 282 and a base 283, which are used to drive the deaerated water tank 210 to rotate as a whole, that is, universal rotation in any direction and any angle. The second rotating motor 281 is located at the end of the center line of the connecting structure to drive the connecting structure 270 and the deaerated water tank 210 to rotate 360°. The center line of the connecting structure is perpendicular to the center line 212 of the deaerated water tank, and the ends of the center line of the connecting structure are the two corresponding intersections of the center line of the connecting structure on the connecting structure 270. The second rotating motor 281 can be set at only one end or at both ends, depending on actual needs. The second connecting structure 282 is used to support the second rotating motor 281 and the deaerated water tank 210, is connected to the two ends of the center line of the connecting structure, and is fixed to the support surface through the base 283. In one embodiment, Figure 1 The second connection structure 282 is a semicircular connection ring that is concentric with the connection structure 270 and has a larger radius, and the base 283 is fixedly installed at the lower end of the semicircular connection ring. Of course, according to actual needs, the second connection structure 282 can be in other shapes, such as a rod-shaped structure that is fixed to the support surface at both ends of the center line of the connection structure through the base 283, which is not strictly limited here. During the universal rotation of the deaerated water tank 210, the internal water continuously hits the inner wall of the box, and the gas in the water is precipitated and escapes through the vent valve 211 at the concave part of the top of the deaerated water tank 210.

[0095] The rotating motor 220 receives the opening and closing instructions of the control unit 600 through the rotating motor control signal line, and transmits its operating status to the control unit 600 through the rotating motor status signal line; the second rotating motor 281 receives the opening and closing instructions of the control unit 600 through the second rotating motor control signal line, and transmits its operating status to the control unit 600 through the second rotating motor status signal line. When the control unit 600 controls the second rotating motor 281 to stop working, it is necessary to control the deaeration water tank 210 to return to the original state with the top facing up, so as to facilitate the connection between the telescopic hose and the water injection pipe 230 and the water extraction pipe 240; the telescopic motor 291 receives the opening and closing instructions of the control unit 600 through the telescopic motor control signal line to inject or extract water, and transmits its operating status to the control unit 600 through the telescopic motor status signal line.

[0096] Example 3

[0097] The third rotary degassing unit S3 includes a degassing water tank 210, a rotating motor 220, a water injection pipe 230 and a water extraction pipe 240, wherein the number of the water injection pipes 230 is greater than or equal to one. The same parts as those in Example 1 are not repeated here. The rotating motor 220 is located at the top of the degassing water tank 210, and the water inlet pipe 110 passes through the rotating motor 220 and is connected to a plurality of water injection pipes 230 in the degassing water tank 210 for water injection, such as 1, 2, 3, 4 or more. The rotating motor 220 drives all the water injection pipes 230 to rotate, stirring the water in the water tank like an egg stirrer, causing a vortex in the water, and precipitating countless bubbles that rise to the water surface, and then escape from the air release valve 211 at the top of the degassing water tank 210. Since the deaerated water tank 210 itself does not rotate, the water extraction pipe 240 can be combined with the water delivery pipe 150 and located at the lower side wall of the deaerated water tank 210, so that the extracted deaerated water is not affected by the gas at the top; at this time, the deaerated water can be extracted by gravity in the deaerated water tank, and there is no need to set up a booster pump 140. The rotating motor 220 receives the start and stop instructions of the control unit 600 through the rotating motor control signal line, and transmits its operating status to the control unit 600 through the rotating motor status signal line.

[0098] The above-mentioned embodiment 1 is an example of the first rotary degassing unit S1 performing degassing work alone, the embodiment 2 is an example of the second rotary degassing unit S2 performing degassing work alone, and the embodiment 3 is an example of the third rotary degassing unit S3 performing degassing work alone. When the first rotary degassing unit S1, the second rotary degassing unit S2 and the third rotary degassing unit S3 are used in combination for the second or even the Nth degassing operation in the Nth degassing operation, the water injection pipe 230 is connected to the water delivery pipe 150 of the previous degassing device, and the water extraction pipe 240 is connected to another water delivery pipe 150.

[0099] As an example, the bottom of the deaeration water tank 210 and the cache water tank 300 are both provided with drain plugs (not shown), and the inner walls of the deaeration water tank 210 and the cache water tank 300 are both provided with liquid level sensors.

[0100] Specifically, in this embodiment, the bottom of the degassing water tank 210 and the buffer water tank 300 are provided with drain plugs to prevent the residual water inside from being drained when not in use for a long time, thereby improving the service life of the water tank. The inner walls of the degassing water tank 210 and the buffer water tank 300 are provided with liquid level sensors, which are embedded micro sensors, including a high liquid level sensor 530, a middle level sensor 540 and a low liquid level sensor 550, such as Figure 1 and Figure 3As shown, they are respectively installed at the upper, middle and lower positions of the inner wall of the water tank to monitor the water level in the water tank and transmit the liquid level signal to the control unit 600 through the high liquid level sensor state signal line, the middle liquid level sensor state signal line and the low liquid level sensor state signal line. Of course, according to actual needs, one or a combination of the high liquid level sensor 530, the middle level sensor 540 and the low liquid level sensor 550 can also be installed, which is not strictly limited here.

[0101] In addition, the high liquid level sensor 530 cannot be placed close to the top of the water tank, but should be placed at a height of about three-quarters of the volume of the water tank. It has been proven that leaving a space of about one-quarter of the volume of the water tank is beneficial to the degassing and exhausting effect of the water tank, and is also beneficial to improving the degassing and exhausting efficiency of the water tank.

[0102] As an example, a flow sensor 510 and a water pressure sensor 520 are also provided in the water inlet pipe 110 and the drain pipe 430 .

[0103] Specifically, in this embodiment, the flow sensor 510 and the water pressure sensor 520 are installed on the water inlet pipe 110 and the drain pipe 430, and are respectively used to monitor the flow and water pressure on the main water inlet pipe and the flow and water pressure on the main drain pipe, so as to ensure that the flow and water pressure of the airless water delivered to the target user meet the usage requirements, and transmit the flow signal and water pressure signal to the control unit 600 through the flow sensor status signal line and the water pressure sensor status signal line respectively.

[0104] like Figure 4 The control unit 600 is provided with a control touch screen, which displays the operation status and operating state of the present invention in real time, and realizes intelligent and fully automatic control of the present invention. Its power supply line 610 is an AC380V cable, which meets the power demand on the ship. It can also be linked with user equipment, meteorological and hydrological observation equipment and water pump 410. When the user equipment is connected to the signal line 640 to monitor the power equipment such as the propeller in reverse, or when the meteorological and hydrological observation equipment is connected to the signal line 650 to monitor the strong wind and wave sea conditions, that is, the wind level and wave level signal ≥ the set value input in advance by the control unit 600, the control unit 600 automatically opens the water inlet electric valve 120, closes the bypass electric valve 170, and performs degassing.

[0105] When the control unit 600 detects through the user device connecting signal line 640 that the power equipment such as the propeller is running, or detects through the meteorological and hydrological observation equipment connecting signal line 650 that the sea surface is calm, that is, the wind level and wave level signals are < the set values ​​input in advance by the control unit 600, the control unit 600 automatically opens the bypass electric valve 170 and closes the water inlet electric valve 120. The seawater is not degassed and is directly supplied to the target user through the water pump 410.

[0106] The control unit 600 also has remote control, operation display and comprehensive fault alarm functions. It transmits the operation status and comprehensive fault alarm signal of the present invention to the superior monitoring center of the ship through the remote operation status display and comprehensive fault alarm signal line 630; and receives remote control from the monitoring personnel of the superior monitoring center through the remote control signal line 620. The monitoring personnel of the superior monitoring center only need to click the screen with a mouse on the monitoring console to remotely control the operation of the present invention.

[0107] As an example, the drainage pipe 430 behind the water pump 410 adopts a magnetic levitation pipeline.

[0108] Specifically, in order to prevent the vibration of the traditional high-power water pump 410 from being transmitted to the drain pipe 430 and the shipboard around the drain pipe 430 bracket, and to eliminate the noise caused by these vibrations, in this embodiment, the drain pipe 430 behind the water pump 410 adopts a magnetic levitation pipeline.

[0109] like Figure 5a and Figure 5b As shown, in addition to the drain pipe 430, the magnetic suspension pipeline also includes a pipeline expansion hose 440, a magnet 450, a thin-walled bracket outer tube 710, a base 720 and an electromagnetic structure 740. A section of pipeline expansion hose 440 is connected to each end of the drain pipe 430 to compensate for the displacement of the drain pipe 430 in the vertical direction of the pipeline. On the outer wall of the drain pipe 430, a plurality of magnets 450 are evenly arranged at a certain distance along the extension line of the pipeline and at a certain angle along the circumference of the pipeline. From the cross-sectional end of the drain pipe 430, the magnet 450 is located at the corresponding position of the upper, lower, left and right center lines of the drain pipe 430.

[0110] The outer tube 710 of the thin-walled support is sleeved on the outside of the magnet 450 of the drain pipe, and an electromagnetic structure 740 is arranged on its inner wall corresponding to the magnet 450. One end of the base 720 is connected to the outer tube 710 of the thin-walled support, and the other end is connected to a supporting surface such as a floor, a ceiling or a wall. When water flows through the drain pipe 430, an electric current is passed through the electromagnetic structure 740, and under the action of the electromagnetic structure 740 and the magnet 450, the drain pipe 430 is suspended at the center of the outer tube 710 of the thin-walled support, and the drain pipe 430 does not contact the base 720, so that the vibration will not be transmitted to the base 720 and the supporting surface, thereby eliminating noise. When there is no water flowing through the drain pipe 430, the current passed through the electromagnetic structure 740 is adjusted, so that the drain pipe 430 slowly moves to the base 720 and is adsorbed and fixed on the electromagnetic structure 740 at the base 720.

[0111] Furthermore, multiple sections of thin-walled support outer tubes 710 of different lengths may be provided, and adjacent thin-walled support outer tubes 710 are connected by a sealing zipper 750. An electromagnetic structure 740 is provided on the inner wall of the thin-walled support outer tube 710 corresponding to the outside of the drain pipe magnet 450, and the inner wall of the thin-walled support outer tube 710 outside other drain pipes does not need to be provided with an electromagnetic structure 740. The total length of the thin-walled support outer tube 710 is greater than or equal to the length of the pipeline to be protected, and sealing structures 730 are provided at the ends of the thin-walled support outer tubes 710 at the outermost ends. After the drain pipe 430 passes through the sealing structure 730, vacuum is drawn to form a vacuum chamber between the drain pipe 430, the thin-walled support outer tube 710 and the sealing structure 730 to provide sound insulation and heat insulation protection for the drain pipe 430. The magnetic levitation pipeline can be controlled by a control unit 600 (not shown). The control unit 600 is electrically connected to the electromagnetic structure 740 to control the electromagnetic structure 740 to energize in the forward direction, energize in the reverse direction, increase the current, decrease the current and cut off the power to control the suspension and fixation of the magnetic levitation pipeline.

[0112] As an example, the water inlet electric valve, the water delivery electric valve, and the bypass electric valve are screen-type stop valves, and the electric stop check valve is a screen-type stop check valve.

[0113] Specifically, in this embodiment, the screen-type stop valve includes a shell 11, a fixed structure 12, an electromagnetic structure 740, a guide rod 21, a screen 22, a magnet 450 and a control structure 30. The shell 11 is a hollow structure with openings at both ends. Its outer diameter, wall thickness and material are the same as those of the connected pipeline. It is fixed between two sections of pipeline flanges through a fixed structure 12 such as a fixed orifice plate circumferentially arranged on the side wall of the shell 11. The electromagnetic structure 740 is symmetrically arranged on the inner wall of the shell 11 corresponding to both ends of the center line of the shell, and the guide rod 21 is fixed to the inner wall of the shell 11 along or parallel to the center line of the shell corresponding to the electromagnetic structure 740. In detail, the extension direction of the pipeline is the Z direction, wherein the positive Z direction is the rear and the negative Z direction is the front; in a plane perpendicular to the extension direction of the pipeline, the two directions perpendicular to each other are the X direction and the Y direction respectively. The guide rod 21 is fixed to the inner wall of the housing 11 along the center line of the housing in the X direction. The electromagnetic structure 740 is located at the front of the guide rod 21 at E and C in the Z direction. In the X direction, it is located at both ends of the guide rod 21. Its height is symmetrical with respect to the guide rod 21 in the Y direction. Figure 6b An opening is provided in the middle of the screen 22, and the guide rod 21 is passed through the opening to be movably connected to the housing 11. The screen 22 is made of elastic material, and the contact between it, the guide rod 21 and the housing 11 has a sealing property. The magnet 450 is fixed to the folded edges on both sides of the screen 22 corresponding to the electromagnetic structure 740, and the magnetic poles are opposite. Under the magnetic force of the electromagnetic structure 740, the screen 22 is driven to unfold and fold along the guide rod 21. When unfolded, the four sides of the screen 22 are completely in contact with the inner wall of the housing 11, and the medium in the pipeline is completely blocked to one side. Figure 6aWhen folded, the screen 22 is stacked in the center of the housing, and the medium inside the pipeline can flow smoothly, such as Figure 6c . A flow sensor is installed on the pipe section where backflow of the pipeline needs to be prevented, and the screen-type stop valve becomes a screen-type stop check valve. The control structure 30 is located on the outer wall of the housing 11, and is electrically connected to the electromagnetic structure 740 and the control unit 600. According to the instructions of the control unit 600, the electromagnetic structure 740 is controlled to be energized in the forward direction, energized in the reverse direction, increase the current, decrease the current, and cut off the power, thereby controlling the screen-type stop valve or screen-type stop check valve to realize automatic opening, closing, and flow regulation. The screen-type stop valve and screen-type stop check valve are light in weight and occupy a small space, and are suitable for use in this system.

[0114] In summary, the rotary degassing device of the present invention is electrically connected to the connecting unit, the rotary degassing unit, the drainage unit and the control structure through the control unit, remotely displays the operating status and the comprehensive fault alarm signal of the rotary degassing device, and performs remote control to realize the intelligent fully automatic operation function, improve the degassing efficiency and save labor costs; the rotary degassing device can realize linkage with the user equipment and the meteorological and hydrological observation equipment through the control unit, automatically identify the ship status or the wind and wave conditions on the sea surface, and automatically adjust the degassing function and the bypass function, thereby automatically protecting the user equipment and saving energy.

[0115] The rotating motor drives the degassing water tank or the water injection pipe to rotate, and cooperates with the swing motor to make the degassing water tank swing as a whole, or cooperates with the rotating motor to drive the dehydration water tank to rotate as a whole, so as to remove the gas that affects the operation of the user system and damages the equipment and pipelines, and effectively prevents the gas in the water from entering the water pump and causing the user's equipment to shut down, providing a guarantee for the high-performance operation of the user's equipment and ensuring the safety of navigation; the air release valve only allows gas to escape, avoiding the air vent from splashing out of the seawater with bubbles to pollute the environment inside the ship, and eliminating the maintenance work of the crew; it also avoids cavitation and pipeline "water hammer" phenomenon on the inner wall of the pipeline and the inner wall of the user's equipment, protects the safety of the use of the pipeline system and the user's equipment, and greatly reduces the economic cost and the noise inside the pipeline; it can be used for degassing of seawater systems and freshwater systems, and can be used for ships and land buildings, with strong applicability and a wide range of applications.
