Description

Technical Field

[0001] This invention relates to the technical field of water conservancy regulation, specifically to a water-saving regulation device. Background Technology

[0002] Water conservation, as a crucial means of water resource management, aims to effectively reduce unnecessary waste and improper use of water resources, thereby significantly improving the overall utilization efficiency of water resources. Water conservancy projects are specially designed and constructed facility systems whose main function is to scientifically and rationally control and allocate surface water and groundwater in nature to ensure the rational allocation and efficient utilization of water resources, thereby meeting the needs of agricultural irrigation, urban water supply, flood control and disaster reduction, and many other aspects.

[0003] The prior art describes a water-saving control device, including an inlet seat with a filter screen inside, a diversion seat fitted on the inlet seat, a connecting pipe connected to the diversion seat, and several diversion pipes on the connecting pipe. It also includes a drive component, which drives a gear to rotate via a transmission assembly. The gear drives a rotating seat and a cleaning assembly to rotate. The rotating assembly drives the cleaning component to rotate, and the cleaning component cleans the filter screen. The rotating assembly drives a contact wheel to move to a moving groove. The gear drives a cam to rotate. The cam presses against the contact wheel, causing the contact wheel to move in the moving groove and causing the rotating assembly to rotate relative to the rotating seat. The rotating assembly drives the cleaning component to rotate relative to the cleaning assembly, achieving self-cleaning of the cleaning component.

[0004] While the aforementioned technologies can ensure effective cleaning of the filter screen and achieve the expected cleaning effect, thereby guaranteeing the normal function of the filter screen and extending its service life, the impurities scraped off by the cleaning components are directly scattered into the water flow channel of the water inlet seat. There is no dedicated directional collection and isolation structure, and it is affected by the impact of water flow and the turbulence generated by the cleaning action. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a water-saving control device for water conservancy, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A water-saving control device includes a water inlet base and a U-shaped housing. Two sealing rings are welded to the inner wall of the water inlet base, and a filter screen is disposed between the two sealing rings. One end of the slot of the U-shaped housing extends through the wall of the water inlet base into the interior. The slot of the U-shaped housing fits over the two sealing rings and the filter screen, and the filter screen is rotatably connected to the slot of the U-shaped housing. An arc-shaped baffle is provided inside the U-shaped housing at the outer wall of the two sealing rings. Side plates are fixed to the sides of the two arc-shaped baffles away from the filter screen. A driving assembly is provided between the two side plates to control the rotation of the filter screen within the water inlet base. An inclined plate is provided at the slot of the U-shaped housing on the water inlet side of the filter screen. One side of the inclined plate is fixedly connected to the inner wall of the U-shaped housing, and a silicone scraper is fixed to the other side of the inclined plate.

[0008] The U-shaped housing has a cleaning component on one side of the outer wall outside the water inlet seat. The cleaning component is used to work with the silicone scraper to extract the scraped impurities and send the filtered water back into the water inlet seat.

[0009] Specifically, the filter screen consists of an annular plate and two filter screens. The outer walls on both sides of the annular plate are in sliding contact with two sealing rings. The outer walls on both sides of the annular plate are embedded with elastic sealing rings. The inner ring of the annular plate is divided into two areas by a connecting plate. The two filter screens are fixed in the two areas respectively. A rotating shaft is fixed at the center of both sides of the connecting plate. The ends of the two rotating shafts are rotatably connected to the inner wall of the U-shaped shell.

[0010] Specifically, the driving assembly includes a drive motor, a driving gear, and a driven gear. The drive motor is mounted on the outer wall of the U-shaped housing by screws. A protective shell is fitted around the drive motor and fixedly connected to the outer wall of the U-shaped housing by screws. The driving gear and the driven gear are meshed and connected. Both the driving gear and the driven gear are located between two side plates. The outer ring wall of the annular plate is provided with inner teeth along the circumference. The tooth surface of the driven gear meshes with the tooth surface of the inner teeth.

[0011] Specifically, in this technical solution, a first shaft and a second shaft, which are rotatably connected to the two side plates, are fixedly inserted at the center of the driving gear and the driven gear, respectively. One end of the first shaft passes through the side plate, and the output end of the drive motor extends into the interior through the shell wall of the U-shaped housing. The output end of the drive motor is connected to the first shaft through a magnetic coupler.

[0012] Specifically, in this technical solution, several parallel fixed sleeves are provided above the inclined plate. The ends of the fixed sleeves are fixedly connected to the inner sidewall of the U-shaped shell. A compression spring is fixed inside each of the fixed sleeves. An abutment rod is fixed to one end of each compression spring. The ends of the abutment rods protrude through the fixed sleeves and contact the mesh surface of the filter screen. The end faces of the abutment rods are all spherical.

[0013] Specifically, in this technical solution, a cam is fixed to the outer wall of the first shaft on one side of the drive gear, and a fixing rod is welded to the inner wall of the U-shaped housing away from the slot at the cam. A return spring is sleeved on the outer wall of the fixing rod. One end of the return spring is fixedly connected to the inner wall of the U-shaped housing, and a push plate is fixed to the other end of the return spring. The convex end of the cam contacts the surface of the push plate.

[0014] Specifically, in this technical solution, a pressure sensor is embedded in the end face of the fixing rod, and the top and bottom of the push plate are embedded with ball bearings that roll in contact with the inner top and bottom walls of the U-shaped housing.

[0015] Specifically, the cleaning assembly includes a negative pressure chamber and a suction pump. The negative pressure chamber is fixed to the outer wall of the U-shaped housing with screws. The suction pump is fixed to the bottom of the negative pressure chamber with screws and its suction port is connected to the inside of the chamber. An L-shaped suction pipe is provided inside the U-shaped housing on the side near the negative pressure chamber. One end of the L-shaped suction pipe passes through an arc-shaped baffle, and the other end of the L-shaped suction pipe passes through the shell wall of the U-shaped housing and is connected to the inside of the negative pressure chamber.

[0016] Specifically, in this technical solution, the output port of the suction pump is connected to a return pipe, which extends through the water inlet seat and into the interior, and a filter cloth is installed inside the negative pressure box.

[0017] Specifically, in this technical solution, the outer wall of the water inlet seat is symmetrically connected with connecting pipes away from the water inlet, and the outer walls of the two connecting pipes are fixedly fitted with diverter seats. The ports of the two connecting pipes can be quickly connected to external pipelines through flanges.

[0018] In summary, the present invention has the following advantages: by constructing a closed cleaning space through a U-shaped shell, the filter screen is rotated by the drive component, so that the silicone scraper head scrapes off impurities in real time in an environment isolated from water flow impact. The negative pressure suction component simultaneously draws the impurities into the negative pressure box, avoiding backflow or dispersion of impurities with turbulence. This solves the problems of incomplete impurity cleaning, easy secondary adhesion, and easy wear of transmission structure in the prior art, and significantly improves the stability and service life of water-saving regulation in water conservancy.

[0019] The detection structure composed of abutment rods can monitor the integrity of the filter screen in real time, preventing filter screen damage from going undetected and causing large particles of impurities to enter downstream pipes or transmission areas. Specifically, when the filter screen is damaged, if any abutment rod is inserted into the hole, the filter screen will stop rotating. Due to the non-rigid connection characteristics of the magnetic coupler, the first shaft will also stop rotating. At this time, the cam will no longer press the push plate, and the pressure sensor will not detect the pressure change at intervals, sending a signal to the control system to indicate that the filter screen is damaged and needs to be replaced, thus forming a complete filter screen status monitoring and protection mechanism.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] It should be noted that a PLC controller is also installed outside the water inlet seat 1. The PLC controller is electrically connected to the drive motor 401, the suction pump 501 and the pressure sensor on the fixing rod 206 through wires to realize signal acquisition and command output. The PLC controller also integrates an alarm module (such as an audible and visual alarm) and a shutdown trigger module, which are installed on the outside of the protective shell 201 or in a nearby control box for easy observation by maintenance personnel.

[0032] In this embodiment, please refer to Figures 1-8 As shown, a water-saving control device includes an inlet seat 1 and a U-shaped housing 2. The outer wall of the inlet seat 1, away from the inlet, is symmetrically connected with connecting pipes 101. Diverter seats 102 are fixedly fitted onto the outer walls of both connecting pipes 101. The ports of both connecting pipes 101 can be quickly connected to external pipelines via flanges. Two sealing rings 103 are welded to the inner wall of the inlet seat 1. A filter screen 7 is provided between the two sealing rings 103. The filter screen 7 consists of an annular plate 701 and two filter screens 70. The annular plate 701 has two outer walls on both sides that slide in contact with two sealing rings 103. Both outer walls on both sides of the annular plate 701 are embedded with elastic sealing rings. The inner ring of the annular plate 701 is divided into two areas by the connecting plate 702. Two filters 704 are fixed in the two areas respectively. A rotating shaft 705 is fixed at the center of both sides of the connecting plate 702. The ends of the two rotating shafts 705 are rotatably connected to the inner wall of the U-shaped housing 2. The outer ring wall of the annular plate 701 is provided with inner teeth 703 along the circumference.

[0033] One end of the slot of the U-shaped housing 2 extends through the wall of the water inlet seat 1 and into the interior. The slot of the U-shaped housing 2 is fitted around the two sealing rings 103 and the outside of the filter screen 7. The filter screen 7 is rotatably connected to the slot of the U-shaped housing 2. Inside the U-shaped housing 2, an arc-shaped baffle 202 is provided at the outer wall of the two sealing rings 103. The side of the two arc-shaped baffles 202 away from the filter screen 7 is fixed with a side plate 203. A drive assembly 4 is provided between the two side plates 203. The drive assembly 4 is used to control the rotation of the filter screen 7 in the water inlet seat 1. An inclined plate 3 is provided at the slot of the U-shaped housing 2 on the water inlet side of the filter screen 7. One side of the inclined plate 3 is fixedly connected to the inner wall of the U-shaped housing 2. A silicone scraper head 301 is fixed on the other side of the inclined plate 3.

[0034] A cleaning component 5 is provided on the outer wall of one side of the U-shaped housing 2 outside the water inlet seat 1. The cleaning component 5 is used to work with the silicone scraper head 301 to extract the scraped impurities and send the filtered water back into the water inlet seat 1. The cleaning component 5 includes a negative pressure box 505 and a suction pump 501. The negative pressure box 505 is fixed to the outer wall of the U-shaped housing 2 with screws. The suction pump 501 is fixed to the bottom of the negative pressure box 505 with screws and the suction port is connected to the inside of the box. An L-shaped suction pipe 502 is provided on the side of the U-shaped housing 2 near the negative pressure box 505. One end of the L-shaped suction pipe 502 passes through the arc-shaped baffle 202, and the other end of the L-shaped suction pipe 502 passes through the shell wall of the U-shaped housing 2 and is connected to the inside of the negative pressure box 505. The output port of the suction pump 501 is connected to a return pipe 503. The return pipe 503 passes through the water inlet seat 1 and extends into the interior. A filter cloth 504 is installed inside the negative pressure box 505.

[0035] Water flows in from the inlet of the inlet seat 1, and after being filtered by the filter screen 704, impurities in the water are removed. The clean water flows to the connecting pipe 101, and then is distributed to each branch pipe through the distributor seat 102 to achieve stable water supply under water-saving regulation. During this process, the PLC controller starts the drive motor 401 in the drive assembly 4, which drives the inner gear 703 to rotate through the gear set, thereby causing the annular plate 701 and the filter screen 704 to rotate slowly around the rotating shaft 705, so that each area of ​​the filter screen 704 is evenly stressed, avoiding excessive accumulation of impurities in some areas.

[0036] As the annular plate 701 rotates, when the filter screen 704 rotates to the area in contact with the silicone scraper head 301, the silicone scraper head 301, supported by the inclined plate 3, elastically scrapes off the impurities attached to the surface of the filter screen 704. Since the U-shaped housing 2, the sealing ring 103, and the annular plate 701 form a closed cleaning space, the scraped impurities will not diffuse with the water flow to the main channel of the inlet seat 1 or the area of ​​the transmission components. Simultaneously, the PLC controller will also start the suction pump 501, creating a negative pressure inside the negative pressure box 505. Impurities and water from the closed space are then drawn into the negative pressure box 505 through the L-shaped suction pipe 502. The impurities are intercepted by the filter cloth 504, and the filtered clean water flows through… The suction pump 501 pressurizes the water and returns it to the main channel of the inlet seat 1 through the return pipe 503. This solves the problems of incomplete cleaning of impurities, easy secondary adhesion, and easy wear of the transmission structure in the prior art. It significantly improves the stability and service life of water-saving regulation. At the same time, the driving gear 403 and driven gear 404 of the drive component 4 are located in the closed cavity formed by the two side plates 203, which are physically isolated from the clean area. The elastic sealing rings and sealing retaining rings 103 on both sides of the annular plate 701 form a sliding seal to prevent water and impurities from entering the transmission cavity. This avoids the gear teeth, bearings and other components from jamming or wearing due to the adhesion of impurities, and extends the service life of the transmission system.

[0037] Please see Figure 5 , Figure 7 and Figure 8 As shown, the drive assembly 4 includes a drive motor 401, a drive gear 403, and a driven gear 404. The drive motor 401 is mounted on the outer wall of the U-shaped housing 2 by screws. A protective shell 201 is fitted over the drive motor 401 and is fixedly connected to the outer wall of the U-shaped housing 2 by screws. The drive gear 403 and the driven gear 404 are meshed together. Both the drive gear 403 and the driven gear 404 are located between the two side plates 203. The tooth surface of the driven gear 404 meshes with the tooth surface of the inner tooth 703. A first shaft 4031 and a second shaft 4041, which are rotatably connected to the two side plates 203, are fixedly inserted through the center of the drive gear 403 and the driven gear 404, respectively. One end of the first shaft 4031 passes through the side plate 203. The output end of the drive motor 401 extends through the shell wall of the U-shaped housing 2 into the interior. The output end of the drive motor 401 and the first shaft 4031 are connected by a magnetic coupler 402.

[0038] The PLC controller starts the drive motor 401, and the output of the drive motor 401 drives the magnetic coupler 402 to rotate. The magnetic coupler 402 transmits power to the first shaft 4031 through non-contact magnetic transmission. The first shaft 4031 drives the drive gear 403 to rotate. The drive gear 403 meshes with the driven gear 404, and the driven gear 404 drives the inner tooth 703 to rotate. The inner tooth 703 is fixed on the annular plate 701, which in turn causes the annular plate 701 to rotate around the rotating shaft 705. The annular plate 701 drives the two filter screens 704 to rotate synchronously, realizing the function of uniform filtration and impurity removal in each area of ​​the filter screen 704. At the same time, the non-rigid connection characteristic of the magnetic coupler 402 can automatically slip when the filter screen 704 is obstructed, avoiding overload damage to the drive motor 401.

[0039] Please see Figure 5 - Figure 8 As shown, several fixed sleeves 6 are arranged side by side above the inclined plate 3. The ends of the fixed sleeves 6 are fixedly connected to the inner side wall of the U-shaped housing 2. A compression spring 601 is fixed inside the fixed sleeves 6. A contact rod 602 is fixed to one end of the compression spring 601. The ends of the contact rods 602 pass through the fixed sleeves 6 and contact the mesh surface of the filter screen 704. The end faces of the contact rods 602 are all spherical 6021. A pressure sensor is embedded in the end face of the fixed rod 206. The top and bottom of the push plate 204 are embedded with balls that roll in contact with the inner top and bottom walls of the U-shaped housing 2.

[0040] A cam 4032 is fixed to the outer wall of the first shaft 4031 on one side of the drive gear 403. A fixing rod 206 is welded to the inner wall of the U-shaped housing 2 away from the slot at the cam 4032. A return spring 205 is sleeved on the outer wall of the fixing rod 206. One end of the return spring 205 is fixedly connected to the inner wall of the U-shaped housing 2. A push plate 204 is fixed to the other end of the return spring 205. The convex end of the cam 4032 contacts the plate surface of the push plate 204.

[0041] When the drive motor 401 drives the first shaft 4031 to rotate, the cam 4032 rotates synchronously. Its convex end periodically presses the push plate 204, causing the push plate 204 to overcome the elastic force of the return spring 205 and move away from the cam 4032. When the convex end of the cam 4032 rotates away from the push plate 204, the elastic force of the return spring 205 pushes the push plate 204 to return to its original position. This process repeats, forming the reciprocating motion of the push plate 204. During this process, the pressure sensor embedded in the end face of the fixed rod 206 continuously detects the pressure change caused by the push plate 204 abutting. When the filter screen 704 is intact and undamaged, during the rotation of the filter screen 704, the abutting rod 602, under the elastic force of the compression spring 601, always maintains flexible contact between the spherical surface 6021 and the surface of the filter screen 704. The drive assembly 4 operates normally, the cam 4032 regularly presses the push plate 204, and the pressure sensor can detect the interval and regular pressure change signal and transmit the signal to the PLC controller.

[0042] When the filter screen 704 develops a hole due to wear or impurity impact, any one of the abutting rods 602, under the pushing force of the compression spring 601, inserts into the hole in the filter screen 704. Due to the mutual obstruction between the abutting rod 602 and the filter screen 704, the annular plate 701 cannot continue to rotate, thus causing the filter screen 7 to stop rotating. Furthermore, because the output end of the drive motor 401 is connected to the first shaft 4031 via a magnetic coupler 402, the non-rigid connection characteristic of the magnetic coupler 402 means that when the filter screen 7 is obstructed and stops rotating, the first shaft... 4031 will also stop rotating. At this time, cam 4032 will no longer press the push plate 204. The pressure sensor will not detect the pressure change of the interval, so it will send a signal to the PLC controller. After receiving the signal, the PLC controller will trigger the alarm module to issue an audible and visual alarm, reminding the maintenance personnel that the filter 704 is damaged and needs to be replaced. At the same time, the shutdown trigger module will control the drive motor 401 to stop running, so as to prevent the equipment from continuing to run when the filter 704 is damaged and causing more serious damage, thus forming a complete filter 704 status monitoring and protection mechanism.

[0043] The working principle of this invention is as follows:

[0044] Water flows in from the inlet of inlet seat 1, and after being filtered by filter screen 704 to remove impurities, the clean water flows to connecting pipe 101, and then is distributed to each branch pipe through distributor seat 102, achieving stable water supply under water-saving regulation. During this process, the PLC controller starts the drive motor 401 in drive assembly 4. The output end of drive motor 401 drives magnetic coupler 402 to rotate. Magnetic coupler 402 transmits power to first shaft 4031 through non-contact magnetic transmission. First shaft 4031 drives the drive gear. When wheel 403 rotates, the driving gear 403 meshes with the driven gear 404 for transmission. The driven gear 404 drives the inner tooth 703 to rotate. The inner tooth 703 is fixed on the annular plate 701, which in turn causes the annular plate 701 to rotate around the rotating shaft 705. The annular plate 701 drives the two filter screens 704 to rotate synchronously, realizing the function of uniform filtration and impurity removal in each area of ​​the filter screen 704. At the same time, the non-rigid connection characteristic of the magnetic coupler 402 can automatically slip when the filter screen 704 is obstructed, avoiding overload damage to the drive motor 401.

[0045] When the first shaft 4031 rotates, the cam 4032 rotates synchronously, and its convex end periodically presses the push plate 204, causing the push plate 204 to overcome the elastic force of the return spring 205 and move away from the cam 4032. When the convex end of the cam 4032 rotates away from the push plate 204, the elastic force of the return spring 205 pushes the push plate 204 to return to its original position. This process repeats, forming the reciprocating motion of the push plate 204. During this process, the pressure sensor embedded in the end face of the fixed rod 206 continuously detects the pressure changes caused by the push plate 204 abutting. When the filter screen 704 is intact and undamaged, during the rotation of the filter screen 704, the abutting rod 602, under the elastic force of the compression spring 601, always maintains flexible contact between the spherical surface 6021 and the surface of the filter screen 704, and the drive assembly 4 operates normally. The cam 4032 regularly presses the push plate 204, and the pressure sensor can detect the interval and regular pressure change signal and transmit the signal to the PLC controller.

[0046] When the annular plate 701 rotates, when the filter screen 704 rotates to the area in contact with the silicone scraper head 301, the silicone scraper head 301, supported by the inclined plate 3, elastically scrapes off the impurities attached to the surface of the filter screen 704. Since the U-shaped housing 2, the sealing ring 103, and the annular plate 701 form a closed cleaning space, the scraped impurities will not spread with the water flow to the main channel of the water inlet seat 1 or the area of ​​the transmission components. At the same time, the PLC controller will also start the suction pump 501 to create a negative pressure inside the negative pressure box 505. The impurities and water flow in the closed space are sucked into the negative pressure box 505 through the L-shaped suction pipe 502. The impurities are intercepted by the filter cloth 504. The filtered clean water flow is pressurized by the suction pump 501 and flows back to the main channel of the water inlet seat 1 through the return pipe 503.

[0047] When the filter screen 704 develops a hole due to wear or impurity impact, any one of the abutting rods 602, under the pushing force of the compression spring 601, inserts into the hole in the filter screen 704. Due to the mutual obstruction between the abutting rod 602 and the filter screen 704, the annular plate 701 cannot continue to rotate, thus causing the filter screen 7 to stop rotating. Since the output end of the drive motor 401 is connected to the first shaft 4031 through the magnetic coupler 402, the non-rigid connection characteristic of the magnetic coupler 402 means that when the filter screen 7 stops rotating due to obstruction, the first shaft 4031 will also stop rotating. At this time, the cam 4032 no longer presses the push plate 204, and the pressure sensor cannot detect the pressure change at intervals. It then sends a signal to the PLC controller. After receiving the signal, the PLC controller triggers the alarm module to issue an audible and visual alarm, reminding maintenance personnel that the filter screen 704 is damaged and needs to be replaced.
