[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a filter online cleaning debris collection device, including a cleaning component 100, including a water collection tank 101, a descaling component 102 arranged in front of the water collection tank 101 and located on the outside of the water collection tank 101, a collecting component 103 arranged inside the water collection tank 101, and a guide component 104 arranged in the water collection tank 101 and located on one side of the collecting component 103; wherein the guide component 104 guides the debris on the water collection tank 101 into the collecting component 103.

[0031] Preferably, the water collecting pool 101 is in a "convex" shape. The "convex" water collecting pool 101 is an open water collecting pool, the upper part of which is hollowed out, and water flows from the lower side of the "convex" shape to the upper side.

[0032] Preferably, the descaling member 102 is located outside the water collecting pool 101, specifically at the upper side of the "convex" water collecting pool, that is, the side with a smaller opening, that is, the downstream position of the water flow.

[0033] Furthermore, the water inlet of the "convex" shaped water collection tank 101 is connected to the mechanical cooling ventilation tower, and flows to the circulating water pump after passing through the descaling component 102, and the circulating water is pumped into the condenser of the circulating water pump box.

[0034] Preferably, the descaling member 102 has the functions of descaling and monitoring the water pressure flowing out of the water collection tank 101 .

[0035] In summary, the water pressure discharged from the sump is monitored in real time by the descaling component 102. After comparing the real-time water pressure with the set value, the residual impurities on the surface of the filter are flushed by the descaling component 102, and the impurities are uniformly collected in the collecting component 103 through the guide component 104. The impurities in the collecting component 103 are lifted up through the transmission component, thereby avoiding the problems of manual lifting and impurity accumulation.

[0036] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention, provides a filter screen online cleaning debris collection device, including a filter screen 101a arranged on the drainage side of the water collection tank 101.

[0037] Preferably, the filter screen 102 is located at the edge of the smaller opening of the convex water collecting tank 101 .

[0038] The descaling member 102 includes a nozzle 102a disposed outside the filter 101a and a pressure sensor 102b located on the same side as the nozzle 102a.

[0039] Preferably, a connector 102c is provided between the nozzle 102a and the pressure sensor 102b, and the connector is connected with the water inlet pipeline of the nozzle 102a and the connecting column 102d connected to the pressure sensor 102b. The connecting column 102d is located behind the nozzle 102a, that is, the water flows through the nozzle 102a first and then through the pressure sensor 102b.

[0040] Preferably, multiple nozzles 102a and pressure sensors 102b are provided, and nozzle 102a is a high-pressure nozzle. Nozzle 102a can be rotated at the connection position and controlled by control member 106. Nozzle 102a adopts cluster flushing to flush filter 101a. The spacing between each nozzle is the same to ensure that the flushing area is not missed.

[0041] The collecting member 103 includes at least one collecting frame 103a, a rotating shaft 103e driving the collecting frame 103a to rotate, and a paddle 103d driving the rotating shaft 103e to rotate by water flow, wherein the paddle 103d is located inside the filter screen 101a.

[0042] Preferably, in the present embodiment, two collecting frames 103a are symmetrically arranged, a connecting rod 103c is arranged between the two collecting frames 103a for connecting the two collecting frames 103a, and both ends of the connecting rod 103c are fixedly connected to the two collecting frames 103a respectively.

[0043] Preferably, the collecting frame 103a is provided with through holes 103b distributed on all inner walls of the collecting frame 103a, and the size of the through holes is smaller than the aperture size of the filter screen 101a, that is, the collecting frame 103a can accommodate smaller impurities.

[0044] Furthermore, the rotating shaft 103e is fixedly arranged in the middle section of the connecting rod 103c, and the rotating shaft 103e is fixedly connected to the paddle 103d. The paddle 103d can rotate under the action of the nozzle 102a, thereby driving the collection box 103a to rotate and rise, avoiding manual lifting.

[0045] It should be noted that the radius of the blade 103 d is smaller than the size of the filter screen 101 a , and the blade 103 d is located inside the guide member 104 .

[0046] The guide member 104 includes a fixed end 104b and a guide end 104a disposed inside the filter screen 101a;

[0047] The guide end 104a gradually moves closer to the inner wall of the water collecting pool 101 .

[0048] Preferably, the fixed end 104b is fixedly connected to the inner wall of the sump 101, and the inner diameter of the fixed end 104b or the size of the opening connected to the filter screen 101a is larger than the radius of the filter screen 101a.

[0049] Preferably, in this embodiment, the guide member 104 is conical, that is, the radius of the fixed end 104b remains unchanged, and the radius of the guide end 104a is: the farther away from the filter screen 101a, the larger the radius of the guide end 104a.

[0050] Furthermore, two symmetrically arranged collecting frames 103a are arranged at the outer wall of the maximum radius of the guide end 104a, and a through hole is opened at the overlapping position of the guide end 104a and the collecting frame 103a, so that impurities can enter the interior of the collecting frame 103a through the through hole, and then be carried out of the water in the sump 101 by the rotation of the paddle 103d.

[0051] A connector 102c is provided between the nozzle 102a and the pressure sensor 102b, and a transmission member 105 is provided on the connector 102c.

[0052] In summary, when there are too many impurities on the filter 101a, that is, the pressure sensor 102b detects that the drainage pressure of the sump 101 is weakened, the nozzle 102a is started, and the water spraying pressure of the nozzle 102a is greater than the drainage pressure of the sump 101, and the impurities on the filter 101a are flushed into the guide end 104a, and the water spraying direction of the nozzle 102a is further changed, so that the impurities move along the guide end 104a, and finally enter the interior of the collection frame 103a through the through hole opened at the overlap of the guide end 104a and the collection frame 103a, and the impurities are taken out of the sump 101 through the rotation of the paddle 103d.

[0053] Example 3, reference Figures 1 to 5 , which is the third embodiment of the present invention, provides a filter screen online cleaning debris collection device, including a connector 102c disposed between a nozzle 102a and a pressure sensor 102b, and a transmission member 105 disposed on the connector 102c. The transmission member 105 includes a transmission screw 105a transmission-connected to the connector 102c and a motor 105b providing power to the transmission screw 105a.

[0054] Preferably, the transmission screw 105a is a lead screw, and the motor 105b is a servo motor, which can accurately control the displacement of the connector 102c, that is, accurately control the position of the nozzle 102a to remove impurities from the filter 102a.

[0055] A control component 106 is disposed outside the water collection pool 101 , and the control component 106 controls the water spraying pressure, direction, and direction of the spray head 102 a according to current feedback information.

[0056] The control component 106 also issues a power instruction to the transmission component 105 according to the feedback information, and the drive motor 105b starts.

[0057] The control component 106 is a control box, which is integrated with a high-pressure water pump that provides the nozzle 102a and a PLC control panel that processes the pressure sensor 102b. The control panel is provided with a water pressure threshold and limit values ​​of different water pressures, such as high, medium, and low values, which are compared with the data of the pressure sensor 102b to control the pressure output by the high-pressure water pump, that is, the water pressure of the nozzle 102a. In addition, the control box is also provided with a driving element for controlling the servo motor and the nozzle 102a, which can remotely drive the servo motor and the nozzle 102a, so that the nozzle can completely remove scale on the filter 101a from multiple angles and directions.

[0058] Example 4, reference Figure 6 , which is the fourth embodiment of the present invention, and provides an online cleaning method. It includes: after the water collection tank is drained through the filter screen, the pressure sensor determines whether the current drainage volume is lower than the threshold;

[0059] If yes, the nozzle is started according to the feedback value of the pressure sensor;

[0060] Preferably, the threshold value is the minimum water pressure value required for heat exchange between the condenser and the turbine. If the water flow pressure detected by the pressure sensor still cannot reach the minimum water pressure value after subsequent pressurization by the circulating water pump, the pressure sensor will feed back the signal to the inside of the control box, so that the control box drives the high-pressure water pump to work, allowing the nozzle to perform multi-angle, multi-directional and complete work.

[0061] Among them, if the signal detected by the pressure sensor matches a specific value, such as the water pressure is too low to a certain degree or just too low, then the control component, i.e. the control box, will receive the feedback and appropriately adjust the output power of the high-pressure water pump so that the nozzle can properly spray out the appropriate water flow pressure, so as to achieve the effect of increasing the service life of the nozzle and reducing energy consumption.

[0062] If not, drain normally.

[0063] In summary, the nozzle is activated by the signal fed back by the pressure sensor to perform descaling operations on the filter in various modes, and the filter residues in different situations can be cleaned.
