The brush plate of the cleaning mechanism has bristles and a nozzle, and its end block is connected to the screw swing plate. In addition, the filter box and the cleaning box are separated by a filter. The water pump draws liquid from the filter box through a liquid suction pipe to supply the nozzle.

Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving pumps, belongs to F04D29 / 46, and particularly relates to an energy-saving pumping fluid output system. Background Art

[0002] In today's industrial production landscape, which prioritizes energy conservation and emissions reduction, optimizing the energy consumption of various types of machinery and equipment has become a key issue. Brake pads, core components of automotive braking systems, require cleaning during their production process to ensure product quality. However, traditional brake pad cleaning systems often consume high amounts of energy, making it difficult to meet energy conservation requirements.

[0003] Traditionally, brake pad cleaning equipment has been used to run continuously at high power. Both the cleaning fluid pump and the motor that drives the brake pads operate at a fixed high power mode. This not only wastes a significant amount of electricity, but can also lead to equipment overheating due to excessive energy consumption, increasing maintenance costs and shortening equipment lifespan.

[0004] Using a frequency converter to adjust the pump speed can be divided into two types: open-loop control: This control method is relatively simple. It adjusts the frequency converter output frequency according to a pre-set frequency command, thereby controlling the motor speed. For example, in some small irrigation systems where flow accuracy is not high, different irrigation flows are roughly set according to the crop growth stage, and the frequency converter outputs the corresponding frequency to drive the pump motor through open-loop control. However, this method is susceptible to external interference, such as grid voltage fluctuations and load changes, which may cause the actual speed to deviate from the set speed.

[0005] Closed-loop control: Closed-loop control incorporates a feedback loop into the system. This typically involves a flow sensor or pressure sensor installed at the pump outlet to detect the actual flow or pressure, feeding the signal back to the VFD controller. The controller compares the feedback signal with the setpoint and, based on the deviation, adjusts the VFD's output frequency to bring the pump's actual operating parameter (flow or pressure) closer to the setpoint. In large urban water supply systems, closed-loop control is often employed to precisely control water pressure and flow, ensuring stable and efficient water supply.

[0006] Closed-loop control is generally used in flushing and cleaning applications. However, to improve the utilization rate of the flushing liquid, existing flushing and cleaning systems generally filter the flushing liquid before use. The flushing liquid is divided into a raw liquid receiving tank and a filter tank, which are separated by a filter. Therefore, when using a closed-loop control method, if a liquid level sensor is directly used to detect the liquid level difference in the two tanks to operate the inverter, the fluctuation of the liquid level of the cleaning liquid will lead to inaccurate measurement, resulting in frequent operation of the inverter and frequent current fluctuations, which is not conducive to energy saving. Summary of the Invention

[0007] The present invention provides an energy-saving pumping fluid output system to solve the problem that when the cleaning fluid is circulated, the existing system is difficult to adjust the cleaning time and the cleaning fluid supply speed according to the permeability of the filter.

[0008] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0009] The cleaning fluid of the cleaning tank is cleaned by the filter element and the filter element is connected to the cleaning fluid outlet of the cleaning tank, and the cleaning fluid outlet of the cleaning tank is cleaned by the filter element.

[0010] Furthermore, two screws are symmetrically connected to the cleaning box for rotation, and U-shaped frames are symmetrically connected to both sides of the cleaning box. The two ends of the two screws are respectively connected to the two U-shaped frames for rotation, and when the running speed of the water pump decreases, the rotation speed of the screws decreases;

[0011] It also includes a cleaning mechanism and a placement mechanism, the cleaning mechanism includes a brush plate, the lower surface of the brush plate is connected to bristles and a nozzle, the end of the brush plate is provided with a clamping block, the screw is connected to a wobble plate, and the wobble plate rotates in the clamping block;

[0012] The placement mechanism includes a loading plate, and threaded holes that cooperate with the two screw rods are respectively opened on both sides of the loading plate.

[0013] Furthermore, the cleaning mechanism also includes a control block sliding on the brush plate, an L-shaped hole is opened in the control block, the L-shaped hole is connected to the liquid inlet pipe, a spring is connected between the control block and the brush plate, when the loading plate moves to the lower part of the brush plate, the loading plate pushes the control block to move upward, so that the L-shaped hole is connected to the nozzle.

[0014] Furthermore, the water pump is connected to a discharge pipe, and the discharge pipe is communicated with the liquid inlet pipe.

[0015] Furthermore, the placement mechanism also includes four pin rods connected to the four corners of the lower surface of the loading plate, and the four pin rods are slidably connected to a lower feeding plate. A pad is placed on the lower feeding plate, and a through hole is opened on the loading plate to cooperate with the pad. After the lower feeding plate is moved up, the pad is inserted into the loading plate, and the brake pad to be cleaned is placed on the upper part of the pad.

[0016] Furthermore, the placement mechanism also includes two cylinders symmetrically connected to both sides of the cleaning box, and the output ends of the two cylinders are commonly connected to a rectangular plate. When the cylinders are extended and retracted, the rectangular plate rises and falls to drive the blanking plate to move vertically.

[0017] Furthermore, it also includes a detection mechanism, which includes a wiping cloth that slides vertically on the upper part of the U-shaped frame, a horizontal plate that slides horizontally on the upper part of the U-shaped frame, and a light source arranged on the upper part of the wiping cloth, and a photosensitive sensor is arranged on the horizontal plate. The wiping cloth moves down and contacts the cleaned brake pad and then moves up. The horizontal plate moves horizontally to the lower part of the wiping cloth and the photosensitive sensor corresponds vertically to the light source.

[0018] Furthermore, a mounting plate is provided at the lower portion of the U-shaped frame, and a plurality of electric telescopic rods corresponding to the plurality of light sensors are provided on the mounting plate. The output ends of the electric telescopic rods are connected to top blocks, and a through hole is provided on the rectangular plate to fit the gap with the top block. When the light intensity received by the light sensor is low, the corresponding electric telescopic rod extends and causes the corresponding top block to abut against the lower portion of the cushion block.

[0019] Furthermore, a fixing frame is connected to the U-shaped frame, and the transverse plate is slidably connected to the fixing frame.

[0020] Furthermore, a mounting frame is vertically slidably connected to the fixing frame, two rollers are symmetrically connected to the mounting frame, and two ends of the wiping cloth are respectively wound around the two rollers.

[0021] The beneficial effects of the present invention are analyzed as follows:

[0022] The cleaning fluid of the present invention is cleaned by the suction cup and the suction cup is sucked up, and the suction cup is sucked up and down ...

[0023] The brake pads to be cleaned are placed on the placement mechanism, and the external motor electric screw is started to rotate. The two screws are driven by a belt pulley, so that the loading plate threadedly connected to the two screws can move axially on the screw and enter the cleaning box. When the screw rotates, the swing plate set at the end of the screw swings synchronously, so that the swinging swing plate can drive the brush plate to slide back and forth in the cleaning box through the card block, so that the bristles on the lower surface of the brush plate clean the brake pads entering the cleaning box. At the same time, the water pump is started, so that the cleaning fluid is sprayed to the brake pads through the nozzle, and the brake pads are cleaned with the brush bristles. The used cleaning fluid flows into the cleaning box and then passes through the filter to isolate granular debris such as metal impurities and enter the filter box. The liquid suction pipe port of the water pump is immersed below the liquid level in the filter box, so as to ensure that the water pump can extract the cleaning fluid in the filter box. When the impurity content of the used cleaning fluid is too high, the impurities will clog the filter. At this time, the liquid level in the filter box drops, so that the liquid level in the filter box is lower than the cleaning box. At this time, the first float is higher than the second float, causing the elastic rope to pull the sliding block to slide. After the displacement sensor detects the sliding of the sliding block, it sends a signal to the control system. The control system controls the operation of the external motor and the variable frequency speed regulator matched with the water pump, so that the speed of the external motor and the water pump drive motor is reduced, so that the cleaning fluid in the filter box is not immediately drained. At the same time, after the speed of the external motor driving the screw is reduced, the brake pad can stay in the cleaning box longer, making up for the lack of sufficient supply in the cleaning box. When the staff finds that the operating speed of the conveying mechanism has decreased, it is necessary to replace the cleaning fluid in the cleaning box and the filter box, and clean the filter screen at the same time. By sensing the permeability of the filter screen through the liquid level difference of the cleaning fluid, the operating speed of the water pump and the external motor is adaptively changed, ensuring the cleaning effect while reducing the energy consumption of the water pump. The combination of the elastic rope and the sliding block greatly reduces the impact of liquid level fluctuations on the data detected by the displacement sensor. In combination with the variable frequency speed regulator, the energy consumption of the water pump is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] Examples, such as Figures 1-10 As shown, an energy-saving pumping fluid output system includes a conveying mechanism 100 and a placing mechanism 300. The conveying mechanism 100 includes a cleaning box 110, and two screws 130 are symmetrically connected to the cleaning box 110 for rotation. The placing mechanism 300 includes a loading plate 310, and threaded holes that cooperate with the two screws 130 are respectively opened on both sides of the loading plate 310; it also includes a cleaning mechanism 200, and the cleaning mechanism 200 includes a brush plate 210, and the lower surface of the brush plate 210 is connected to bristles 230 and a nozzle 240. A block 220 is provided at the end of the brush plate 210, and a swing plate 140 is connected to the screw 130, and the swing plate 140 rotates in the block 220; the outside of the cleaning box 110 is connected to a filter box 280, and a filter is provided between the filter box 280 and the cleaning box 110. Net 270, the cleaning box 110 is connected to a water pump 260 for supplying cleaning liquid to the nozzle 240, and the water pump 260 is connected to a liquid extraction pipe 262, the end of the liquid extraction pipe 262 is immersed in the filter box 280, and the side wall of the cleaning box 110 is connected to a mounting block 150. The first float 160 and the second float 170 are vertically floating in the cleaning box 110 and the filter box 280 respectively, and an elastic pull rope 180 is connected between the first float 160 and the second float 170. The mounting block 150 is provided with a displacement sensor and a sliding block 151 detected by the displacement sensor. When the liquid level in the filter box 280 is lower than that in the cleaning box 110, the elastic pull rope 180 pulls the sliding block 151 to slide, thereby reducing the operating speed of the screw 130 and the water pump 260.

[0041] The working mechanism of the fluid output system provided in this embodiment is as follows:

[0042] The brake pad to be cleaned is placed on the placement mechanism 300, and the external motor electric screw 130 is started to rotate. The two screws 130 are driven by a belt pulley, so that the loading plate 310 threadedly connected to the two screws 130 can move axially on the screws 130 and enter the cleaning box 110. When the screws 130 rotate, the swing plate 140 set at the end of the screw 130 swings synchronously, so that the swinging swing plate 140 can drive the brush plate 210 to slide back and forth in the cleaning box 110 through the block 220, so that the brush plate The brush bristles 230 on the lower surface of 210 clean the brake pads entering the cleaning box 110. At the same time, the water pump 260 is started, so that the cleaning liquid is sprayed to the brake pads through the nozzle 240. With the brushing of the brush bristles 230, the brake pads are cleaned. The used cleaning liquid flows into the cleaning box 110, and then passes through the filter screen 270 to isolate the metal impurities and other granular debris, and enters the filter box 280. The liquid suction pipe 262 port of the water pump 260 is immersed below the liquid level in the filter box 280, thereby ensuring that the water pump 260 The cleaning liquid in the filter box 280 can be extracted. When the impurity content of the used cleaning liquid is too high, the impurities will clog the filter 270. At this time, the liquid level in the filter box 280 drops, so that the liquid level in the filter box 280 is lower than the cleaning box 110. At this time, the first float 160 is higher than the second float 170, so that the elastic rope 180 pulls the sliding block 151 to slide. After the displacement sensor detects the sliding of the sliding block 151, it sends a signal to the control system, and the control system controls the external motor and the variable speed drive matched with the water pump 260. The frequency regulator is running, so that the speed of the driving motor of the external motor and the water pump 260 is reduced, so that the cleaning fluid in the filter box 280 will not be immediately drained. At the same time, after the speed of the external motor driving the screw 130 is reduced, the brake pad can stay in the cleaning box 110 for a longer time, making up for the shortage of reduced supply of the cleaning box 110. When the staff finds that the running speed of the conveying mechanism 100 is reduced, it is necessary to replace the cleaning fluid in the cleaning box 110 and the filter box 280, and at the same time, it is necessary to clean the filter screen 270.

[0043] The first floating plate 160 and the second floating plate 170 are restrained by sliders to slide vertically within the cleaning box 110 and the filter box 280, respectively. The elastic pull rope 180 can undergo a small amount of elastic deformation, so that when the liquid level fluctuates, it will not directly pull the sliding block 151 to slide. Only when the liquid level difference increases and exceeds the deformation of the elastic pull rope 180 will the sliding contact of the mounting block 150 slide.

[0044] By sensing the permeability of the filter 270 based on the level difference of the cleaning liquid, the operating speed of the water pump 260 and the external motor is adaptively changed, thereby ensuring the cleaning effect while reducing the energy consumption of the water pump 260. The cooperation between the elastic pull rope 180 and the sliding block 151 greatly reduces the impact of liquid level fluctuations on the data detected by the displacement sensor. In conjunction with the variable frequency speed regulator, the energy consumption of the water pump 260 is reduced.

[0045] Regarding the structure of the conveying mechanism 100, specifically:

[0046] The conveying mechanism 100 further includes a U-shaped frame 120 symmetrically connected to both sides of the cleaning box 110 , and two ends of the two screw rods 130 are rotatably connected to the two U-shaped frames 120 respectively.

[0047] The provision of the two U-shaped frames 120 enables the two screw rods 130 to be installed and fixed.

[0048] Regarding the structure of the cleaning mechanism 200, specifically:

[0049] The cleaning mechanism 200 also includes a control block 250 that slides on the brush plate 210. An L-shaped hole 251 is opened in the control block 250. The L-shaped hole 251 is connected to a liquid inlet pipe 252. A spring 253 is connected between the control block 250 and the brush plate 210. When the loading plate 310 moves to the lower part of the brush plate 210, the loading plate 310 pushes the control block 250 to move upward, so that the L-shaped hole 251 is connected to the nozzle 240.

[0050] When the loading plate 310 moves to the inside of the cleaning box 110, the upper surface of the loading plate 310 can press the control block 250, so that the control block 250 overcomes the elastic force of the spring 253 and moves upward, thereby making the L-shaped hole 251 in the control block 250 connected with the nozzle 240. At this time, the liquid inlet pipe 252 inputs the cleaning liquid into the nozzle 240, so that the nozzle 240 on the upper part of the loading plate 310 sprays the cleaning liquid to clean the brake pads, reducing the amount of cleaning liquid used, while enhancing the impact force of the cleaning liquid and improving the cleaning effect.

[0051] Among the optional methods of this embodiment, the more preferred ones are:

[0052] The water pump 260 is connected to a liquid discharge pipe 261 , which is in communication with the liquid inlet pipe 252 .

[0053] The cleaning fluid extracted by the water pump 260 is discharged through the drain pipe 261. The liquid inlet pipe 252 is a branch pipe arranged on the drain pipe 261, and there are multiple of them. There are also multiple nozzles 240 to ensure the coverage of the brake pad cleaning.

[0054] Regarding the structure of the placement mechanism 300, specifically:

[0055] The placement mechanism 300 also includes four pin rods connected to the four corners of the lower surface of the loading plate 310, and the four pin rods are slidably connected to the unloading plate 320. A pad 330 is placed on the unloading plate 320. A through hole is opened on the loading plate 310 to cooperate with the pad 330. After the unloading plate 320 moves up, the pad 330 is inserted into the loading plate 310, and the brake pad to be cleaned is placed on the upper part of the pad 330.

[0056] When the unloading plate 320 moves upward, it drives the pad 330 to move upward and is inserted into the loading plate 310, so that a plurality of grooves for placing the brake pads are formed on the upper surface of the loading plate 310. The brake pads are placed in these grooves, and then the external motor is started to rotate the screw 130, so that the placement mechanism 300 enters the cleaning box 110 to clean the brake pads.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] The placement mechanism 300 also includes two cylinders 350 symmetrically connected to both sides of the cleaning box 110. The output ends of the two cylinders 350 are commonly connected to a rectangular plate 340. When the cylinders 350 are extended or retracted, the rectangular plate 340 rises and falls to drive the blanking plate 320 to move vertically.

[0059] When placing the brake pads, one or two cylinders 350 are controlled to extend, so that the rectangular plate 340 drives the blanking plate 320 to move upward, so that the pad 330 is inserted into the loading plate 310. At this time, the brake pads can be placed on the loading plate 310. After the brake pads are cleaned, the cylinders 350 are controlled to shorten, so that the rectangular plate 340 no longer pushes the blanking plate 320 upward. At this time, the blanking plate 320 and the rectangular plate 340 move downward synchronously, and the pad 330 and the blanking plate 320 move downward synchronously. The cleaned brake pads are on the top of the pad 330. At this time, the cleaned brake pads can be removed. A placement through hole is opened on the blanking plate 320 that cooperates with the pad 330. The bottom diameter of this placement through hole is smaller than the pad 330, thereby preventing the pad 330 from passing through this placement through hole, so that the upward movement of the blanking plate 320 can synchronize the upward movement of the pad 330.

[0060] Regarding the structure of the detection mechanism 400, specifically:

[0061] The detection mechanism 400 includes a wiping cloth 431 that slides vertically on the upper part of the U-shaped frame 120, a horizontal plate 450 that slides horizontally on the upper part of the U-shaped frame 120, and a light source 440 arranged on the upper part of the wiping cloth 431. A photosensor 460 is provided on the horizontal plate 450. The wiping cloth 431 moves downward and contacts the cleaned brake pad and then moves upward. The horizontal plate 450 moves horizontally to the lower part of the wiping cloth 431 and the photosensor 460 corresponds vertically to the light source 440.

[0062] When the placement mechanism 300 moves from the U-shaped frame 120 at one end to the U-shaped frame 120 inside the other end, it indicates that the cleaning is completed. At this time, the screw 130 stops rotating and the water pump 260 also stops running. Then the wiping cloth 431 moves down and contacts multiple brake pads. The wiping cloth 431 is a white cloth and has good light transmittance. After wiping the cleaned brake pads, the wiping cloth 431 moves up. Then the light source 440 is turned on to illuminate the wiping area. At this time, the horizontal plate 450 moves to directly below the light source 440. If the light transmittance of the wiping cloth 431 after wiping is reduced by a small amount, it means that the wiping cloth 431 is clean, that is, the corresponding brake pads are clean and do not need to be rinsed again. On the contrary, the photosensor 460 detects a high degree of attenuation after the light passes through, which means that the wiping cloth 431 is dirty, and the brake pads corresponding to the wiping cloth 431 are not cleaned and need to be cleaned again.

[0063] Among the optional methods of this embodiment, the more preferred ones are:

[0064] A mounting plate 470 is provided at the lower portion of the U-shaped frame 120, and a plurality of electric telescopic rods 480 corresponding to the plurality of light sensors 460 are provided on the mounting plate 470. The output ends of the electric telescopic rods 480 are connected to the top blocks 490. A through hole is provided on the rectangular plate 340 to fit the gap with the top blocks 490. When the light intensity received by the light sensor 460 is low, the corresponding electric telescopic rod 480 extends and causes the corresponding top blocks 490 to abut against the lower portion of the cushion block 330.

[0065] The light source 440, the groove for placing the brake pad, the pad 330, the light sensor 460 and the electric telescopic rod 480 are all provided in multiple and one-to-one correspondence. When the light sensor 460 detects that the light level through the wiping cloth 431 is reduced, the corresponding electric telescopic rod 480 extends. At this time, the top block 490 on the top of the electric telescopic rod 480 blocks the pad 330, so that the corresponding pad 330 will not move down synchronously with the downward movement of the unloading plate 320. At this time, the brake pad on the upper part of this pad 330 remains in the groove of the loading plate 310 and does not need to be taken out. Subsequently, the control cylinder 350 is extended to replenish the brake pads in the remaining vacant grooves.

[0066] Among the optional methods of this embodiment, the more preferred ones are:

[0067] The U-shaped frame 120 is connected to a fixing frame 410 , and the horizontal plate 450 is slidably connected to the fixing frame 410 .

[0068] Electric sliders or screw rods are provided on both sides of the horizontal plate 450 to move the wiping cloth 431 downward and then upward. Then the horizontal plate 450 moves horizontally to the lower part of the wiping cloth 431, and after the electric telescopic rod 480 is extended, the horizontal plate 450 slides back to its original position.

[0069] Among the optional methods of this embodiment, the more preferred ones are:

[0070] The fixing frame 410 is vertically slidably connected to a mounting frame 420 . Two rollers 430 are symmetrically connected to the mounting frame 420 . Two ends of the wiping cloth 431 are respectively wound around the two rollers 430 .

[0071] The light source 440 is connected to the mounting frame 420. The two rollers 430 are driven to rotate by an external motor. The mounting frame 420 can be driven vertically by a structure such as a hydraulic rod or an electric slider. When the mounting frame 420 moves downward so that the wiping cloth 431 contacts the brake pad, the external motor controls the two rollers 430 to rotate back and forth synchronously by a small amount, so that a relative displacement occurs between the wiping cloth 431 and the brake pad, ensuring the accuracy of the test results. After the test is completed or before the next test, the two rollers 430 rotate synchronously so that the unused wiping cloth 431 moves to the top of the brake pad, and then the cleanliness of the brake pad is tested again.

[0072] It should also be noted that the placement mechanism 300 and the detection mechanism 400 will be reset each time the brake pad is taken or placed.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
