Description

Technical Field

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

[0002] In today's industrial production field that focuses on energy conservation and emission reduction, the energy consumption optimization of various mechanical equipment has become a key issue. As a core component of the automotive braking system, the cleaning process of brake pads is crucial for ensuring product quality. However, traditional brake pad cleaning systems often consume high energy and are difficult to meet the energy-saving requirements.

[0003] In the traditional way, brake pad cleaning mostly uses cleaning equipment that operates continuously at high power. Whether it is the transfer pump for the cleaning fluid or the motor that drives the movement of the brake pads, they all work in a fixed high-power mode. This not only causes a large amount of power waste but also may lead to problems such as overheating of the equipment due to excessive energy consumption, increasing the maintenance cost and shortening the service life of the equipment.

[0004] Using a frequency converter to adjust the speed of a water pump is divided into open-loop control: This control method is relatively simple. It adjusts the output frequency of the frequency converter according to a pre-set frequency command to control the motor speed. For example, in some small irrigation systems with low requirements for flow accuracy, different irrigation flows are roughly set according to the growth stage of crops, and the frequency converter outputs the corresponding frequency through open-loop control to drive the water pump motor. However, this method is easily affected by external interferences such as power grid voltage fluctuations and load changes, resulting in a deviation between the actual speed and the set speed;

[0005] Closed-loop control: Closed-loop control adds a feedback link to the system. Usually, a flow sensor or a pressure sensor installed at the outlet of the water pump is used to detect the actual flow or pressure, and the detected signal is fed back to the controller of the frequency converter. The controller compares the feedback signal with the set value and then adjusts the output frequency of the frequency converter according to the deviation, so that the actual operating parameters (flow or pressure) of the water pump are closer to the set value. In large urban water supply systems, in order to precisely control the water supply pressure and flow, the closed-loop control method is generally adopted to ensure the stability and efficiency of water supply.

[0006] In flushing and cleaning applications, the closed-loop control method is generally adopted. However, in existing flushing and cleaning systems, in order to improve the utilization rate of the flushing fluid, the flushing fluid is generally filtered and then used, which is divided into a raw liquid receiving tank and a filtration tank, and the two are separated by a filter screen. Therefore, when using the closed-loop control method, if the liquid level difference between the two tanks is directly detected by a liquid level sensor to make the frequency converter operate, the measurement will be inaccurate due to the undulation of the liquid level of the cleaning fluid, resulting in frequent operation of the frequency converter and frequent current fluctuations, which is not conducive to energy conservation. Summary of the Invention

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

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

[0009] An energy-saving pumping fluid output system includes a conveying mechanism and a cleaning mechanism. The conveying mechanism includes a cleaning tank. The cleaning mechanism includes a filter tank connected to the outside of the cleaning tank. A filter screen is provided between the filter tank and the cleaning tank. The cleaning tank is provided with a nozzle and a water pump for supplying cleaning liquid to the nozzle. A liquid suction pipe is connected to the water pump, and the end of the liquid suction pipe is immersed in the filter tank. An installation block is connected to the side wall of the cleaning tank. A first floating plate and a second floating plate are vertically floating in the cleaning tank and the filter tank respectively. An elastic pull rope is connected between the first floating plate and the second floating plate. A displacement sensor is provided on the installation block, and a sliding block detected by the displacement sensor is slidably connected thereto. When the liquid level in the filter tank is lower than that in the cleaning tank, the elastic pull rope pulls the sliding block to slide, so that the operating speed of the water pump decreases.

[0010] Furthermore, two screws are symmetrically and rotatably connected in the cleaning tank. U-shaped frames are symmetrically connected to both sides of the cleaning tank. Both ends of the two screws are rotatably connected to the two U-shaped frames respectively. When the operating speed of the water pump decreases, the rotation speed of the screws decreases;

[0011] It further includes a cleaning mechanism and a placing mechanism. The cleaning mechanism includes a brush plate. The lower surface of the brush plate is connected with bristles and a nozzle. A clamping block is provided at the end of the brush plate. A disc is connected to the screw, and the disc rotates in the clamping block;

[0012] The placing mechanism includes a feeding plate, and threaded holes matching with the two screws are respectively opened on both sides of the feeding plate.

[0013] Furthermore, the cleaning mechanism further includes a control block slidable on the brush plate. An L-shaped hole is opened in the control block, and a liquid inlet pipe is communicated with the L-shaped hole. A spring is connected between the control block and the brush plate. When the feeding plate moves to the lower part of the brush plate, the feeding plate pushes the control block to move upward, so that the L-shaped hole is communicated with the nozzle.

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

[0015] Further, the placing mechanism further includes four pin rods connected to the four corners of the lower surface of the loading plate. A blanking plate is slidably connected to the four pin rods. A cushion block is placed on the blanking plate. Through holes matching the cushion block are formed in the loading plate. After the blanking plate moves upward, the cushion block is inserted into the loading plate, and the brake pads to be cleaned are placed on the upper part of the cushion block.

[0016] Further, the placing mechanism further includes two air cylinders symmetrically connected to both sides of the cleaning tank. The output ends of the two air cylinders are jointly connected to a rectangular plate. When the air cylinders expand and contract, the rectangular plate moves up and down to drive the blanking plate to move vertically.

[0017] Further, a detection mechanism is further included. The detection mechanism includes a wiping cloth vertically slidable on the upper part of the U-shaped frame, a cross plate horizontally slidable on the upper part of the U-shaped frame, and a light source arranged on the upper part of the wiping cloth. A photosensitive sensor is arranged on the cross plate. After the wiping cloth moves downward and contacts the brake pads after cleaning and then moves upward, the cross plate moves horizontally to the lower part of the wiping cloth and the photosensitive sensor is vertically corresponding to the light source.

[0018] Further, an installation plate is arranged at the lower part of the U-shaped frame. A plurality of electric telescopic rods corresponding to the plurality of photosensitive sensors are arranged on the installation plate. The output end of the electric telescopic rod is connected to a top block. Through holes with clearance fit with the top block are formed in the rectangular plate. When the light intensity received by the photosensitive sensor is low, the corresponding electric telescopic rod extends and the corresponding top block abuts against the lower part of the cushion block.

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

[0020] Further, an installation frame is vertically slidably connected to the fixing frame. Two rollers are symmetrically connected to the installation frame, and the 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] An energy-saving pumping fluid output system includes a conveying mechanism and a placement mechanism. The conveying mechanism includes a cleaning tank, and two screws are symmetrically and rotatably connected inside the cleaning tank. The placement mechanism includes a feeding plate, and threaded holes matching the two screws are respectively formed on both sides of the feeding plate. It also includes a cleaning mechanism. The cleaning mechanism includes a brush plate. The lower surface of the brush plate is connected with bristles and nozzles. A clamping block is arranged at the end of the brush plate. A swing plate is connected to the screw, and the swing plate rotates inside the clamping block. A filter tank is connected to the outside of the cleaning tank. A filter screen is arranged between the filter tank and the cleaning tank. A water pump for supplying cleaning liquid to the nozzles is connected to the cleaning tank. A liquid suction pipe is connected to the water pump, and the end of the liquid suction pipe is immersed in the filter tank. An installation block is connected to the side wall of the cleaning tank. A first floating plate and a second floating plate respectively float vertically in the cleaning tank and the filter tank. An elastic pull rope is connected between the first floating plate and the second floating plate. The sliding contact of the installation block is connected to the elastic pull rope. When the liquid level in the filter tank is lower than that in the cleaning tank, the elastic pull rope pulls the elastic contact of the installation block to slide, so that the running speeds of the screw and the water pump are reduced.

[0023] Place the brake pads to be cleaned on the placement mechanism, start the external motor to rotate the electric screw, and drive the two screws through the belt pulley, so that the feeding plate threadedly connected to the two screws can axially move on the screws and enter the cleaning tank. When the screws rotate, the swing plates arranged at the ends of the screws swing synchronously. Thus, the swinging swing plates can drive the brush plate to reciprocate in the cleaning tank through the clamping blocks, so that the bristles on the lower surface of the brush plate clean the brake pads entering the cleaning tank. At the same time, start the water pump so that the cleaning liquid is sprayed onto the brake pads through the nozzles. With the brushing of the bristles, the brake pads are cleaned. The used cleaning liquid flows into the cleaning tank, and then through the filtration of the filter screen to isolate granular impurities such as metal impurities and enters the filtration tank. The port of the liquid suction pipe of the water pump is immersed below the liquid level in the filtration tank, so as to ensure that the water pump can extract the cleaning liquid in the filtration tank. When the impurity content of the used cleaning liquid is too high, the impurities block the filter screen. At this time, the liquid level in the filtration tank drops, so that the liquid level in the filtration tank is lower than that in the cleaning tank. At this time, the first floating plate is higher than the second floating plate, so that the elastic pull rope pulls 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 variable frequency speed regulators matched with the external motor and the water pump, so that the driving motor speeds of the external motor and the water pump are reduced. Thus, the cleaning liquid in the filtration tank will not be pumped dry immediately. At the same time, after the driving speed of the external motor driving the screw is reduced, the brake pads can stay in the cleaning tank for a longer time to make up for the shortage of the reduced supply of the cleaning tank. When the staff finds that the running speed of the conveying mechanism is reduced, the cleaning liquid in the cleaning tank and the filtration tank needs to be replaced, and at the same time, the filter screen needs to be cleaned; by perceiving the permeability of the filter screen through the liquid level difference of the cleaning liquid, adaptively changing the running speeds of the water pump and the external motor, not only ensures the cleaning effect, but also reduces the energy consumption of the water pump. The cooperation of the elastic pull rope and the sliding block greatly reduces the influence of the liquid level fluctuation on the data detected by the displacement sensor. With the variable frequency speed regulator, the energy consumption of the water pump is reduced. Brief Description of the Drawings

[0040] Example, such as Figures 1-10 As shown, an energy-saving pumping fluid output system includes a conveying mechanism 100 and a placement mechanism 300. The conveying mechanism 100 includes a cleaning tank 110. Two screws 130 are symmetrically and rotatably connected inside the cleaning tank 110. The placement mechanism 300 includes a feeding plate 310. Threaded holes cooperating with the two screws 130 are respectively formed on both sides of the feeding plate 310. It further includes a cleaning mechanism 200. The cleaning mechanism 200 includes a brush plate 210. The lower surface of the brush plate 210 is connected with bristles 230 and nozzles 240. A clamping block 220 is arranged at the end of the brush plate 210. A disc plate 140 is connected to the screw 130. The disc plate 140 rotates inside the clamping block 220. A filter tank 280 is connected to the outside of the cleaning tank 110. A filter screen 270 is arranged between the filter tank 280 and the cleaning tank 110. A water pump 260 for supplying cleaning liquid to the nozzles 240 is connected to the cleaning tank 110. A liquid suction pipe 262 is connected to the water pump 260. The end of the liquid suction pipe 262 is immersed in the filter tank 280. An installation block 150 is connected to the side wall of the cleaning tank 110. A first floating plate 160 and a second floating plate 170 are respectively vertically floating in the cleaning tank 110 and the filter tank 280. An elastic pull rope 180 is connected between the first floating plate 160 and the second floating plate 170. A displacement sensor is arranged on the installation block 150, and a sliding block 151 detected by the displacement sensor is slidably connected. When the liquid level in the filter tank 280 is lower than that in the cleaning tank 110, the elastic pull rope 180 pulls the sliding block 151 to slide, so that the running speeds of the screw 130 and the water pump 260 are reduced.

[0041] The working mechanism of the fluid output system provided by this embodiment:

[0042] Place the brake pads to be cleaned on the placement mechanism 300, start the external motor to rotate the electric screw 130. The two screws 130 are driven by a belt and pulley, so that the feeding plate 310 threadedly connected to the two screws 130 can axially move on the screws 130 and enter the cleaning tank 110. When the screws 130 rotate, the swing plate 140 arranged at the end of the screws 130 swings synchronously. Thus, the swinging swing plate 140 can drive the brush plate 210 to reciprocate in the cleaning tank 110 through the clamping block 220, so that the bristles 230 on the lower surface of the brush plate 210 clean the brake pads entering the cleaning tank 110. At the same time, the water pump 260 is started, so that the cleaning liquid is sprayed onto the brake pads through the nozzle 240. With the cooperation of the brushing of the bristles 230, the brake pads are cleaned. The used cleaning liquid flows into the cleaning tank 110, and then through the filtration of the filter screen 270 to isolate granular impurities such as metal impurities and enter the filtration tank 280. The port of the liquid suction pipe 262 of the water pump 260 is immersed below the liquid level in the filtration tank 280, so as to ensure that the water pump 260 can extract the cleaning liquid in the filtration tank 280. When the impurity content of the used cleaning liquid is too high, the impurities block the filter screen 270. At this time, the liquid level in the filtration tank 280 drops, so that the liquid level in the filtration tank 280 is lower than that in the cleaning tank 110. At this time, the first floating plate 160 is higher than the second floating plate 170. Thus, the elastic pull 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. The control system controls the operation of the external motor and the variable frequency speed regulator matched with the water pump 260, so that the driving motor speeds of the external motor and the water pump 260 are reduced. Thus, the cleaning liquid in the filtration tank 280 will not be pumped dry immediately. At the same time, after the external motor drives the screw 130 to reduce the speed, the brake pads can stay in the cleaning tank 110 for a longer time, making up for the shortage of the reduced supply amount of the cleaning tank 110. When the staff finds that the running speed of the conveying mechanism 100 is reduced, it is necessary to replace the cleaning liquid in the cleaning tank 110 and the filtration tank 280, and at the same time, it is necessary to clean the filter screen 270;

[0043] Both the first floating plate 160 and the second floating plate 170 are vertically slid in the cleaning tank 110 and the filtration tank 280 respectively through slider restrictions. The elastic pull rope 180 can undergo a small amount of elastic deformation, so that when the liquid level of the cleaning liquid fluctuates, it will not directly pull the sliding block 151 to slide. Only when the liquid level difference increases and breaks through the deformation degree of the elastic pull rope 180 will the sliding contact of the mounting block 150 slide;

[0044] By sensing the permeability of the filter screen 270 through the liquid level difference of the cleaning liquid, the operating speeds of the water pump 260 and the external motor are adaptively changed, which not only ensures the cleaning effect but also reduces the energy consumption of the water pump 260. The cooperation of the elastic drawstring 180 and the sliding block 151 greatly reduces the influence of the liquid level fluctuation on the data detected by the displacement sensor. Combined with the frequency converter, 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 U-shaped frames 120 symmetrically connected to both sides of the cleaning tank 110, and both ends of the two screw rods 130 are rotatably connected to the two U-shaped frames 120.

[0047] The setting of the two U-shaped frames 120 enables the installation and fixation of the two screw rods 130.

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

[0049] The cleaning mechanism 200 further includes a control block 250 slidable on the brush plate 210. An L-shaped hole 251 is formed in the control block 250, and a liquid inlet pipe 252 is connected to the L-shaped hole 251. 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 upward, so that the L-shaped hole 251 communicates with the nozzle 240.

[0050] When the loading plate 310 moves into the cleaning tank 110, the upper surface of the loading plate 310 can press the control block 250, so that the control block 250 moves upward against the elastic force of the spring 253, so that the L-shaped hole 251 in the control block 250 is connected to the nozzle 240. At this time, the cleaning liquid pumped by the water pump 260 is input to the nozzle 240 through the liquid inlet pipe 252, so that the nozzle 240 above the loading plate 310 sprays the cleaning liquid to clean the brake pads, reducing the amount of cleaning liquid used, enhancing the impact force of the cleaning liquid, and improving the cleaning effect.

[0051] In an alternative embodiment of the present embodiment, preferably:

[0052] A drain pipe 261 is connected to the water pump 260, and the drain pipe 261 is communicated with the liquid inlet pipe 252.

[0053] The cleaning liquid pumped by the water pump 260 is discharged through the drain pipe 261. The liquid inlet pipe 252 is a branch pipe provided on the drain pipe 261, and there are multiple liquid inlet pipes 252, and there are also multiple nozzles 240, ensuring the coverage range of cleaning the brake pads.

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

[0055] The placing mechanism 300 further includes four pin rods connected to the four corners of the lower surface of the loading plate 310. A blanking plate 320 is slidably connected to the four pin rods together. A cushion block 330 is placed on the blanking plate 320. Through holes cooperating with the cushion block 330 are formed in the loading plate 310. After the blanking plate 320 moves upward, the cushion block 330 is inserted into the loading plate 310, and the brake pads to be cleaned are placed on the upper part of the cushion block 330.

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

[0057] In an alternative embodiment of the present embodiment, preferably:

[0058] The placing mechanism 300 further includes two air cylinders 350 symmetrically connected to both sides of the cleaning tank 110. A rectangular plate 340 is commonly connected to the output ends of the two air cylinders 350. When the air cylinders 350 expand and contract, the rectangular plate 340 moves up and down to drive the blanking plate 320 to move vertically.

[0059] When placing the brake pads, control one or two air cylinders 350 to extend, so that the rectangular plate 340 drives the blanking plate 320 to move upward, so that the cushion block 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, control the air cylinders 350 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 cushion block 330 and the blanking plate 320 move downward synchronously. The cleaned brake pads are at the top of the cushion block 330. At this time, the cleaned brake pads can be removed. A placing through hole cooperating with the cushion block 330 is formed in the blanking plate 320. The bottom diameter of this placing through hole is smaller than that of the cushion block 330, so as to prevent the cushion block 330 from passing through this placing through hole, so that the upward movement of the blanking plate 320 can drive the cushion block 330 to move upward synchronously.

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

[0061] The detection mechanism 400 includes a wiping cloth 431 vertically sliding on the upper part of the U-shaped frame 120, a cross plate 450 horizontally sliding 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 photosensitive sensor 460 is arranged on the cross plate 450. After the wiping cloth 431 moves downward and contacts the cleaned brake pads and then moves upward, the cross plate 450 moves horizontally to the lower part of the wiping cloth 431 and the photosensitive sensor 460 is vertically corresponding 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 at 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 operating. Subsequently, the wiping cloth 431 moves downward and contacts multiple brake pads. The wiping cloth 431 is a white cloth and has good light transmittance. After the wiping cloth 431 wipes the cleaned brake pads, it moves upward. Subsequently, the light source 440 is turned on to irradiate the wiping part. At this time, the cross plate 450 moves to directly below the light source 440. If the reduction in the light transmittance of a part of the wiping cloth 431 after wiping is small, it indicates that the wiping cloth 431 is clean, that is, the corresponding brake pads are cleaned and do not need to be rinsed repeatedly. On the contrary, if the photosensitive sensor 460 detects that the light attenuation after passing through is high, it indicates that the wiping cloth 431 is dirty and the brake pads corresponding to the wiping cloth 431 are not cleaned cleanly and need to be cleaned again.

[0063] In an alternative embodiment of the present embodiment, preferably:

[0064] An installation plate 470 is provided at the lower part of the U-shaped frame 120. A plurality of electric telescopic rods 480 corresponding to the plurality of photosensitive sensors 460 are provided on the installation plate 470. The output end of the electric telescopic rod 480 is connected with a top block 490. A through hole for clearance fit with the top block 490 is provided on the rectangular plate 340. When the light intensity received by the photosensitive sensor 460 is low, the corresponding electric telescopic rod 480 extends and the corresponding top block 490 abuts against the lower part of the cushion block 330.

[0065] The light source 440, the groove for placing the brake pads, the cushion block 330, the photosensitive sensor 460, and the electric telescopic rod 480 are all provided in multiple numbers and correspond one by one. When the photosensitive sensor 460 detects that the light intensity passing through the wiping cloth 431 decreases, the corresponding electric telescopic rod 480 extends. At this time, the top block 490 at the top of the electric telescopic rod 480 blocks the cushion block 330, so that the corresponding cushion block 330 does not move down synchronously with the downward movement of the blanking plate 320. At this time, the brake pads on the upper part of this cushion block 330 remain in the groove of the feeding plate 310 and do not need to be taken out. Subsequently, after controlling the cylinder 350 to extend, the remaining empty grooves are replenished with brake pads.

[0066] In an alternative embodiment of the present embodiment, preferably:

[0067] A fixing frame 410 is connected to the U-shaped frame 120. The cross plate 450 is slidably connected to the fixing frame 410.

[0068] Driving structures such as electric sliders or lead screws are provided on both sides of the cross plate 450 to realize the downward and upward movement of the wiping cloth 431. Subsequently, the cross plate 450 moves horizontally to the lower part of the wiping cloth 431, and the cross plate 450 slides back to its original position after the electric telescopic rod 480 extends.

[0069] In an alternative embodiment of the present embodiment, preferably:

[0070] An installation frame 420 is vertically slidably connected to the fixing frame 410. Two rollers 430 are symmetrically connected to the installation frame 420, and both ends of the wiping cloth 431 are respectively wound around the two rollers 430.

[0071] A light source 440 is connected to the installation frame 420. The two rollers 430 are driven to rotate by an external motor. The installation frame 420 can be driven to move vertically by structures such as a hydraulic rod or an electric slider. After the installation frame 420 moves downward so that the wiping cloth 431 contacts the brake pad, the external motor controls the two rollers 430 to rotate synchronously and reciprocate slightly, so that a relative displacement is generated between the wiping cloth 431 and the brake pad, ensuring the accuracy of the detection result. After the detection is completed or before the next detection, the two rollers 430 rotate synchronously, so that the unused wiping cloth 431 moves to the upper part of the brake pad, and then the cleanliness of the brake pad is detected;

[0072] In addition, it should be noted that after each taking and placing of the brake pad, the placing mechanism 300 and the detection mechanism 400 will be reset.

[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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
