Description

Technical Field

[0001] This application relates to the technical field of indirect air cooling technology, and particularly relates to a surface cleanliness sensing and detecting device for an indirect air-cooled radiator equipped with a cleaning function. Background Art

[0002] The power plant indirect air cooling technology relies on air to indirectly condense the exhaust steam of the steam turbine. This technology does not need to dissipate heat through the evaporation of circulating cooling water, thus avoiding the evaporation loss of water resources. The indirect air cooling system can be divided into the Heller system, the Hamon system, and the SCAL indirect air cooling system.

[0003] Among them, the Fuge type radiator (also known as the aluminum tube and aluminum fin radiator) is the main equipment of the Heller system, including several radiator cooling columns perpendicular to the ground. Two adjacent cooling columns form a cooling triangle with a 60° angle. The other side of the triangle is equipped with louvers to control the air intake and protect the radiator from interference by external factors such as pollen, floating dust, insects, and birds, eliminating potential safety hazards during operation. Inevitably, after long-term use, the heat dissipation effect of the cooling triangle decreases due to the continuous accumulation of stains, so it needs to be cleaned regularly.

[0004] However, the radiators of the indirect air cooling system are usually arranged in a ring shape, and the upper and lower guide rails are arranged in a polygon shape. Constrained by the structural characteristics of the radiator, it is impossible to set up a drag chain automation device on the ground. As a result, the water and electricity pipelines such as the water inlet pipe and cable of the indirect air cooling cleaning device are usually dragged manually on the ground as the cleaning device moves, making it difficult to achieve automated and intelligent detection and cleaning functions.

The implementation modes described in the following embodiments do not represent all implementation modes consistent with this application. They are only examples of systems and methods consistent with some aspects of this application detailed in the claims.

[0027] An intercooled radiator surface cleanliness sensing and detecting device equipped with a cleaning function provided by this application, as Figure 1As shown, it includes: a cable guide rail 1, an upper guide rail 2, a lower guide rail 3, a truss 4, a horizontal walking mechanism 5, a lifting mechanism 6, a cleaning mechanism 7, a water supply mechanism 8, a photoelectric sensor 9 and the control mechanism 10, wherein the cable guide rail 1 is arranged above the upper guide rail 2, and a plurality of cables are arranged in the cable guide rail 1; the upper guide rail 2 is arranged above the truss 4, and the lower guide rail 3 is arranged on the ground; the horizontal walking mechanism 5 is arranged on the lower guide rail 3; an upper roller 41 is provided on the top of the truss 4, and the upper roller 41 is in contact with the upper guide rail 2, and the bottom of the truss 4 is fixed to the horizontal walking mechanism 5 fixed connection; the truss 4 includes a vertical main beam; a plurality of photoelectric sensors 9 are staggered on the truss 4; the lifting mechanism 6 and the water supply mechanism 8 are arranged on the truss 4, the water supply mechanism 8 is arranged at the bottom of the truss 4, and the lifting mechanism 6 is arranged above the water supply mechanism 8; the lifting mechanism 6 can move vertically on the vertical main beam of the truss 4; the cleaning mechanism 7 is arranged on the lifting mechanism 6, and the cleaning mechanism 7 is connected to the water supply mechanism 8; the control mechanism 10 is respectively connected to the horizontal walking mechanism 5, the lifting mechanism 6, the cleaning mechanism 7, the water supply mechanism 8, and the photoelectric sensor 9.

[0028] The cable guide rail 1 is used to organize various cables in the cable guide rail 1 to ensure that the cables are neatly installed. All cables are connected to the equipment from top to bottom, which can make the lines move neatly and orderly with the device, making the site neat and beautiful, and also solves the problem that the cables may be caught in rotating equipment such as rollers.

[0029] The upper guide rail 2 and the lower guide rail 3 are laid along the indirect cooling radiator, and a cleaning area is formed when the indirect cooling radiator is fully laid. The horizontal traveling mechanism 5 can move horizontally along the lower guide rail 3, and the truss 4 can move horizontally along with the horizontal traveling mechanism 5.

[0030] The truss 4 is a lattice-like beam structure, composed of several rods. It spans space and bears weight. It is widely used in building structures and bridge engineering. Compared to solid beams, it uses less material and is lighter, allowing it to accommodate larger spans. It can be constructed from materials such as steel, wood, or reinforced concrete. The truss 4 supports the lifting mechanism 6, cleaning mechanism 7, water supply mechanism 8, and photoelectric sensor 9. The truss 4 has two main beams perpendicular to the ground, which serve as guide rails for the vertical movement of the lifting mechanism 6.

[0031] The cleaning mechanism 7 can move vertically with the lifting mechanism 6. In this way, the cleaning mechanism 7 can move horizontally with the truss 4 and vertically with the lifting mechanism 6 in the cleaning area, so that all parts of the indirect cooling radiator can be cleaned.

[0032] The water supply mechanism 8 is used to provide cleaning water to the cleaning mechanism 7 .

[0033] The photoelectric sensor 9 is staggeredly arranged on two main beams on the side of the truss 4 facing the indirect air-cooled radiator, and is used to detect the cleanliness of the surface of the indirect air-cooled radiator. Based on the data fed back by the photoelectric sensor 9, the control mechanism 10 can determine whether the indirect air-cooled radiator needs to be cleaned. During the cleaning of the entire area, since the reflectivity of the surface of the indirect air-cooled radiator is different before and after cleaning, the cleaning effect can be detected by the photoelectric sensor 9. For local areas with poor cleaning effects, through the feedback signal of the photoelectric sensor 9, the control mechanism 10 can control the cleaning mechanism 7 to perform multiple and focused cleanings to ensure that the cleaning effect meets the requirements.

[0034] The control mechanism 10, as Figure 6 shown, is connected to each mechanism by means of cables or wirelessly, etc., and is used to receive the signals fed back by each sensor and control the operation of devices such as motors and brakes of each mechanism.

[0035] In a schematic embodiment, the horizontal traveling mechanism 5, as Figure 5 shown, includes: a horizontal traveling frame 51, a horizontal traveling mechanism motor 52, lower rollers 53, and anti-derailment hooks 54. Among them, the lower rollers 53 and anti-derailment hooks 54 are arranged at the bottom of the horizontal traveling frame 51, and the lower rollers 53 are in contact with the lower guide rail 3; the horizontal traveling mechanism motor 52 is arranged on the top of the horizontal traveling frame 51, and the horizontal traveling mechanism motor 52 is connected to the lower rollers 53 through a chain.

[0036] The control mechanism 10 can control the horizontal traveling mechanism motor 52 to drive the horizontal traveling mechanism 5 to move horizontally on the lower guide rail 3.

[0037] The anti-derailment hook 54 is used to prevent the horizontal traveling mechanism 5 from derailing from the lower guide rail 3.

[0038] In a schematic embodiment, the horizontal traveling mechanism 5 further includes: a horizontal infrared receiver 55 and a horizontal infrared transmitting probe 56. The horizontal infrared receiver 55 is arranged at the outer frame edge of the horizontal traveling frame 51, and the horizontal infrared transmitting probe 56 is arranged on the lower guide rail 3; the horizontal infrared receiver 55 and the horizontal infrared transmitting probe 56 are on the same optical path.

[0039] The horizontal infrared receiver 55 can receive the infrared rays emitted by the horizontal infrared transmitting probe 56. Through the infrared ranging sensor composed of the horizontal infrared receiver 55 and the horizontal infrared transmitting probe 56, precise traveling and positioning of the horizontal traveling mechanism 5 in the horizontal direction can be achieved.

[0040] In a schematic embodiment, the lifting mechanism 6 includes: a lifting frame 61, a lifting mechanism motor 62, a coupling 63, a winding drum 64, a steel wire rope 65, a fixed pulley 66, and a travel limit switch 67. Among them, the fixed pulley 66 is arranged at the top of the truss 4; one end of the steel wire rope 65 passes around the fixed pulley 66 and is connected to the lifting frame 61, and the other end is wound around the winding drum 64; the lifting mechanism motor 62 is connected to the winding drum 64 through the coupling 63; the travel limit switch 67 is arranged on the truss 4, and the number of the travel limit switches 67 is two, and the travel limit switches 67 are respectively located at the preset maximum travel height and the minimum travel height.

[0041] As Figure 4 shown, the output shaft of the lifting mechanism motor 62 is connected to the shaft of the winding drum 64 through the coupling 63 to drive the winding drum 64 to rotate. The steel wire rope 65 is wound on the winding drum 64, and the steel wire rope 65, the lifting frame 61, and the fixed pulley 66 form a set of closed-loop rotation systems. The control mechanism 10 can control the lifting mechanism motor 62 to drive the lifting frame 61 to move up and down.

[0042] The travel limit switch 67 is used to limit the maximum travel height and the minimum travel height that the lifting frame 61 can reach.

[0043] In a schematic embodiment, the lifting mechanism 6 further includes: a lifting rotation speed sensor 68 and a travel brake caliper 69. The lifting rotation speed sensor 68 is arranged on the fixed pulley 66, and the travel brake caliper 69 is arranged on the lifting frame 61.

[0044] As Figure 2 shown, the lifting rotation speed sensor 68 is arranged on the rotation shaft of the fixed pulley 66. When the measured value of the lifting rotation speed sensor 68 exceeds the set value, it indicates that there may be a risk of breakage of the steel wire rope 65. Through the feedback signal of the lifting rotation speed sensor 68, the control mechanism 10 activates the travel brake caliper 69 arranged at the lower end of the lifting frame 61 to avoid equipment damage and safety accidents caused by the fall of the lifting frame 61.

[0045] In a schematic embodiment, the lifting mechanism 6 further includes: a vertical infrared receiver 610 and a vertical infrared transmitting probe 611. The vertical infrared receiver 610 is arranged on the lifting frame 61, and the vertical infrared transmitting probe 611 is arranged on the truss 4; the vertical infrared receiver 610 and the vertical infrared transmitting probe 611 are on the same optical path.

[0046] The vertical infrared receiver 610 can receive the infrared rays emitted by the vertical infrared emission probe 611. Through the infrared distance measurement sensor composed of the vertical infrared receiver 610 and the vertical infrared emission probe 611, precise movement and positioning of the lifting frame 61 in the vertical direction can be achieved.

[0047] In a schematic embodiment, the cleaning mechanism 7 includes: a spray gun 71, a flipping motor 72, a flipping sprocket 73, a rotating shaft 74, and a flipping limit switch 75. Among them, the spray gun 71 is arranged on the rotating shaft 74, and the rotating shaft 74 is connected to the flipping sprocket 73; the flipping motor 72 is connected to the flipping sprocket 73 through a chain; the flipping limit switch 75 is arranged on the spray gun 71.

[0048] As Figure 3 shown, the cleaning mechanism 7 is arranged on the lifting frame 61 and can move in the vertical direction along with the lifting frame 61. The rotating shaft 74 is in the shape of a long rod. The flipping motor 72 drives the flipping sprocket 73 to rotate, and the flipping sprocket 73 drives the rotating shaft 74 to rotate. The spray gun 71 is fixed on the rotating shaft 74, and the control mechanism 10 controls the flipping motor 72 to continuously switch between forward rotation and reverse rotation to realize the swinging of the spray gun 71.

[0049] The flipping limit switch 75 is arranged at the tail end of the spray gun 71 to prevent the spray gun 71 from being damaged due to excessive rotation.

[0050] In a schematic embodiment, the cleaning mechanism 7 further includes: a flipping speed sensor 76 and a flipping disc brake 77. The flipping speed sensor 76 and the flipping disc brake 77 are arranged on the rotating shaft 74.

[0051] The flipping speed sensor 76 is arranged at the end of the rotating shaft 74 for detecting the rotation speed of the rotating shaft 74. When the rotation speed of the rotating shaft 74 exceeds the allowable value, to avoid damage to equipment such as the spray gun 71 caused by excessive speed, the control mechanism 10 controls the flipping disc brake 77 to reduce the rotation speed of the rotating shaft 74.

[0052] In a schematic embodiment, the water supply mechanism 8 includes: a water pipe 81, a water pump 82, a water tank 83, and a liquid level sensor 84. Among them, the water pump 82 is arranged at the bottom of the truss 4; the liquid level sensor 84 is arranged in the water tank 83; one end of the water pipe 81 is in the water tank 83, and the other end is connected to the spray gun 71 through the water pump 82.

[0053] A large water tank 83 is arranged underground in the cleaning area. One end of the water pipe 81 is immersed in the water tank 83. Through this design method, a pipeline-free design on the ground is achieved, solving the problem of pipeline dragging.

[0054] A liquid level sensor 84 is provided in the water tank 83 . When the water level is lower than the minimum effective water level, the control mechanism 10 starts the remote water supply pump to supply water to the water tank 83 .

[0055] In an exemplary embodiment, a tilt sensor 42 is provided on the top of the truss 4 .

[0056] like Figure 2 As shown, by setting the inclination sensor 42 at the top of the truss 4, when the inclination angle of the device exceeds the allowable value, in order to avoid the truss 4 from tilting too much, which will cause the truss 4 to be overstretched and broken, the inclination sensor 42 signal is fed back to the control mechanism 10, and the control mechanism 10 controls the horizontal walking mechanism 5 to stop, thereby preventing safety accidents.

[0057] The present application provides a surface cleanliness sensing and detection device for an indirect cooling radiator equipped with a cleaning function, comprising: a cable guide 1, an upper guide 2, a lower guide 3, a truss 4, a horizontal walking mechanism 5, a lifting mechanism 6, a cleaning mechanism 7, a water supply mechanism 8, a photoelectric sensor 9 and a control mechanism 10, wherein the cable guide 1 is used to gather various cables, solving the problem that the cables may be caught in rotating equipment such as rollers. A plurality of photoelectric sensors 9 are staggered on the truss 4 to detect whether the indirect cooling radiator needs to be cleaned and the effect of the cleaning. By setting an infrared ranging sensor, the device can be accurately moved and positioned in the horizontal and vertical directions; by setting a plurality of sensors such as an inclination sensor 42, a lifting speed sensor 68, a flip speed sensor 76, a liquid level sensor 84, etc., the safe operation of the device is guaranteed, so that the device can be automatically and intelligently detected and cleaned.
