Technical Field

[0001] The invention relates to the technical field of water supply equipment, in particular to a box-type variable frequency water supply equipment with energy-saving function. Background Art

[0002] The water supply system refers to a complex of reservoirs, water pumps, pipelines and other projects that provide water for different water-using departments according to certain quality requirements. In terms of the technical functions of the water supply system, the entire water supply system should meet the user's needs for water quality, water volume and water pressure. In addition, in the entire infrastructure process and production operation, it is also required that the infrastructure investment is low, the operating cost is low, the operation and management are convenient, and the box-type water supply equipment can be safely produced and give full play to the economic benefits of the entire water supply system;

[0003] The existing water supply device usually cleans the water tank during maintenance. After a long period of water supply, the impurities in the water tank have accumulated into scale, which is difficult to clean. In addition, the scale accumulates on the inner wall and easily corrodes the inner wall, causing damage to the water tank. Summary of the invention

[0007] The staff controls the water inlet to open through the controller, and then the water is transported to the water tank through the water inlet for storage. When the water consumption increases, the controller controls the pump unit to start and the water outlet to open. The water pump in the pump unit draws water from the water tank. The water in the water tank is then transported to the water pump in the pump unit through the water outlet. The water pump draws water into the pipe system, thereby realizing pipeline water supply. During the process of transporting the water in the water tank to the water outlet, the controller controls the cleaning device to start, and the cleaning device then rotates under the action of the water flow. During the rotation of the cleaning device, the inner wall of the water tank is cleaned. The cleaning device cleans away the impurities attached to the inner wall of the water tank to avoid the accumulation of impurities on the inner wall to form scale, thereby extending the maintenance cycle of the water tank and saving the maintenance cost of the water tank. Secondly, the water tank is cleaned by the cleaning device to improve the water quality in the water tank.

[0008] Preferably, a plurality of fixing rings are provided on the rotating shaft, a plurality of supporting arms are provided on the side of the fixing ring away from the rotating shaft, the supporting arms are arranged around the axis of the fixing ring, a plurality of impeller blades are provided between two adjacent supporting arms, and the impeller blades form an angle with the supporting arms.

[0009] Preferably, an electromagnetic coil is provided inside the water tank away from the fixing ring of the support arm, the support arm is a magnetic conductor, a cleaning groove is provided on the side of the support arm close to the water outlet, a cleaning rod is provided in the cleaning groove, and the cleaning rod is rotatably connected to the cleaning groove through a rotating shaft.

[0010] Preferably, a power chamber is provided inside the cleaning groove, and a rotating shaft in the cleaning rod passes through the power chamber and is provided with a rotating gear, the rotating gear is an incomplete gear, a sliding groove is provided on the side of the support arm away from the cleaning groove, a slider is slidably connected in the sliding groove, a pull rope is provided in the sliding groove, one end of the pull rope is connected to the slider, and the other end of the pull rope is connected to the rotating shaft on the cleaning rod, and a torsion spring is provided on the rotating shaft on the cleaning rod.

[0011] Preferably, two movable grooves are provided on the shaft arm of the rotating shaft, one of the movable grooves is provided on the side of the rotating shaft close to the water inlet, and the other movable groove is provided on the side of the rotating shaft close to the water outlet, the fixed ring is slidably connected to the movable groove, an electromagnetic spring is provided in the movable groove, one end of the electromagnetic spring is connected to the fixed ring, and the other end of the electromagnetic spring is connected to the side wall of the movable groove.

[0012] Preferably, the impeller blades on the plurality of fixed rings are arranged in an alternating manner, the impeller blades are combined into a complete impeller, and a filter screen is provided in the water outlet;

[0013] When the controller controls the pump group device to start, the water in the water tank is immediately transported to the pipeline under the action of the water pump, and the water in the water tank moves from one side of the water inlet to the water outlet. During the water transportation process in the water tank, the water flow impacts the impeller blades, and the impeller blades immediately generate a rotational force under the action of the water flow, and the impeller blades immediately rotate. During the rotation of the impeller blades, the impeller blades drive the support arm to rotate, and the rotation of the support arm drives the fixed ring to rotate. When the fixed ring rotates, the fixed ring drives the rotating shaft to rotate;

[0014] Since the support arm is a magnetic conductor, during the rotation of the support arm, the support arm continuously cuts the magnetic flux lines in the electromagnetic coil arranged inside the water tank, so that the electromagnetic coil generates magnetic force, and then magnetism generates electricity. The electricity generated by the electromagnetic coil is transmitted to the battery through the circuit for storage, thereby realizing the utilization rate of resources and achieving the effect of energy saving.

[0015] During the rotation of the support arm, the slider moves under the action of centrifugal force, and the slider moves along the sliding groove to the side away from the fixed ring. Since the electromagnetic coil generates magnetic force during the rotation of the support arm, the magnetic force also attracts the slider to move to the side close to the inner wall of the water tank. During the movement of the slider, the slider drives the pull rope to move, and the pull rope is pulled immediately. During the sliding and pulling process of the pull rope, the pull rope at the other end pulls the rotating shaft on the cleaning rod to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod to rotate, and the cleaning rod moves to the side away from the cleaning groove. After the cleaning rod rotates, it contacts the inner wall of the water tank. When the impeller blades rotate, it drives the support arm to rotate. The rotation of the support arm drives the cleaning rod to rotate. During the rotation of the cleaning rod, the inner wall of the water tank is cleaned, and impurities attached to the inner wall of the water tank are cleaned off to prevent impurities from attaching to the inner wall of the water tank to form scale. Impurities in the water tank are not easily attached to the inner wall of the water tank under the stirring action of the support arm and the impeller blades, which extends the maintenance cycle of the water tank, saves the maintenance cost of the water tank, and improves the water quality in the water tank.

[0016] The rotation drives the rotating gear in the power chamber to rotate. Since the rotating gear is an incomplete gear, when the slider moves to the end of the sliding groove, the rotating gear is freed from the restraint of the teeth, and then the rotating gear is reset under the action of the torsion spring. During the reset process, the rotating gear drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod to reset. The cleaning rod rotates to one side of the cleaning groove, thereby realizing multiple intermittent cleaning of the inner wall of the water tank, improving the cleaning efficiency, thereby improving the cleaning quality;

[0017] When it is necessary to stop the water supply, the controller controls the electromagnetic spring in the moving groove to be energized when controlling the pump unit to be closed. The electromagnetic spring is energized and contracts. During the contraction process, the electromagnetic spring drives the fixed ring to move. The fixed rings on both sides move along the moving groove to the side away from the water inlet and the water outlet respectively. Then the controller controls the pump unit to be closed. At this time, the staggered impeller blades are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, which impacts the impeller blades. The staggered impeller blades disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump unit and protecting the pump unit.

[0018] The cleaned impurities are transported to the water outlet under the action of water flow. During the transportation process, the impurities encounter the filter screen set in the water outlet and are then filtered by the filter plate screen;

[0019] The water flow is used to drive the support arm to rotate. During the rotation of the support arm, the cleaning rod is driven to clean the inner wall of the water tank. At the same time, during the rotation of the support arm, the support arm cuts the magnetic lines of force, causing the electromagnetic coil to generate electricity, thereby improving the utilization rate of resources and achieving energy-saving effects.

[0020] Preferably, a battery is provided between the water tank and the pump assembly, and the angle between the impeller blade and the support arm is 30°-45°.

[0021] Preferably, the pump assembly device is provided with a heat-to-electricity device, the pump assembly device is also provided with a vibration generator, the heat-to-electricity device is electrically connected to a battery, the battery is electrically connected to the vibration generator, and the pump assembly device is provided with a vibration frequency sensor;

[0022] During the rotation of the cleaning device, the magnetic flux lines are cut in the electromagnetic coil, so that the electromagnetic coil generates magnetic force, thereby generating electricity, which is then transmitted to the battery through the circuit for storage. The pump unit is started under the control of the controller, and the water pump in the pump unit generates heat during operation, and the heat is accumulated in the pump unit. The heat-to-electric device is then started under the control of the controller, and the heat-to-electric device immediately converts the heat in the pump unit into electrical energy, which is also transmitted to the battery through the circuit for storage. After the heat-to-electric device converts the heat in the pump unit, the heat dissipation efficiency in the pump unit is improved, and the utilization rate of heat energy is improved, which not only realizes the heat dissipation in the pump unit, but also makes the heat energy utilized;

[0023] Since the water pump generates noise during its operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump unit to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation, thereby achieving the purpose of noise reduction and improving the noise reduction effect of the pump unit.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] 1. Use water flow to drive the support arm to rotate. During the rotation of the support arm, the cleaning rod is driven to clean the inner wall of the water tank. At the same time, during the rotation of the support arm, the support arm cuts the magnetic flux lines, causing the electromagnetic coil to generate electricity, thereby improving the utilization rate of resources and achieving energy-saving effects.

[0026] 2. After the heat-to-electric device converts the heat in the pump unit, the heat dissipation efficiency in the pump unit is improved, and the utilization rate of thermal energy is improved, which not only realizes the heat dissipation in the pump unit, but also makes use of the thermal energy; since the water pump will generate noise during operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it, and then the controller controls the vibration generator in the pump unit to start, and then the battery transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency according to the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation, and then achieving the purpose of noise reduction, and improving the noise reduction effect of the pump unit.

When the water consumption increases, the controller controls the pump unit 2 to start and the water outlet 12 to open, and the water pump in the pump unit 2 draws water from the water tank 1. The water in the water tank 1 is then transported to the water pump in the pump unit 2 through the water outlet 12. The water pump draws water into the pipe system, thereby realizing pipeline water supply. During the process of the water in the water tank 1 being transported to the water outlet 12, the controller controls the cleaning device 3 to start, and the cleaning device 3 then rotates under the action of the water flow. During the rotation of the cleaning device 3, the inner wall of the water tank 1 is cleaned, and the cleaning device 3 cleans off the impurities attached to the inner wall of the water tank 1 to prevent the impurities from accumulating on the inner wall to form scale.

The support arms 33 are arranged around the axis of the fixing ring 32, and a plurality of impeller blades 34 are arranged between two adjacent support arms 33. The impeller blades 34 form an angle with the support arms 33, and the angle between the impeller blades 34 and the support arms 33 is 30°.

[0042] As a specific embodiment of the present invention, an electromagnetic coil is arranged inside the water tank 1 away from the fixing ring 32 of the support arm 33, the support arm 33 is a magnetic conductor, a cleaning groove 35 is arranged on the side of the support arm 33 close to the water outlet 12, a cleaning rod 36 is arranged in the cleaning groove 35, and the cleaning rod 36 is rotatably connected to the cleaning groove 35 through a rotating shaft.

[0043] As a specific embodiment of the present invention, a power chamber 351 is provided inside the cleaning groove 35, and a rotating shaft in the cleaning rod 36 passes through the power chamber 351 and is provided with a rotating gear 352, and the rotating gear 352 is an incomplete gear. A sliding groove 37 is provided on the side of the support arm 33 away from the cleaning groove 35, and a slider 38 is slidably connected in the sliding groove 37. A pull rope is provided in the sliding groove 37, one end of the pull rope is connected to the slider 38, and the other end of the pull rope is connected to the rotating shaft on the cleaning rod 36, and a torsion spring is provided on the rotating shaft on the cleaning rod 36.

[0044] As a specific embodiment of the present invention, two movable grooves 39 are arranged on the shaft arm of the rotating shaft 31, one of the movable grooves 39 is arranged on the side of the rotating shaft 31 close to the water inlet 11, and the other movable groove 39 is arranged on the side of the rotating shaft 31 close to the water outlet 12, the fixed ring 32 is slidably connected to the movable groove 39, and an electromagnetic spring is arranged in the movable groove 39, one end of the electromagnetic spring is connected to the fixed ring 32, and the other end of the electromagnetic spring is connected to the side wall of the movable groove 39.

[0045] As a specific embodiment of the present invention, a plurality of impeller blades 34 on the fixing ring 32 are arranged crosswise, and the impeller blades 34 are combined into a complete impeller, and a filter screen is provided in the water outlet 12;

[0046] When the controller controls the pump assembly device 2 to start, the water in the water tank 1 is immediately transported to the pipeline under the action of the water pump, and the water in the water tank 1 moves from one side of the water inlet 11 to the water outlet 12. During the water transport process in the water tank 1, the water flow impacts the impeller blade 34, and the impeller blade 34 immediately generates a rotational force under the action of the water flow, and the impeller blade 34 immediately rotates. During the rotation of the impeller blade 34, the impeller blade 34 drives the support arm 33 to rotate, and the rotation of the support arm 33 drives the fixed ring 32 to rotate. When the fixed ring 32 rotates, the fixed ring 32 drives the rotating shaft 31 to rotate;

[0047] Since the support arm 33 is a magnetic conductor, during the rotation of the support arm 33, the support arm 33 continuously cuts the magnetic flux lines in the electromagnetic coil disposed inside the water tank 1, so that the electromagnetic coil generates magnetic force, and then magnetism generates electricity. The electricity generated by the electromagnetic coil is transmitted to the battery through the circuit for storage;

[0048] During the rotation of the support arm 33, the slider 38 moves under the action of centrifugal force, and the slider 38 moves along the sliding groove 37 to the side away from the fixed ring 32. Since the electromagnetic coil generates magnetic force during the rotation of the support arm 33, the magnetic force also attracts the slider 38 to move to the side close to the inner wall of the water tank 1. During the movement of the slider 38, the slider 38 drives the pull rope to move, and the pull rope is pulled immediately. During the process of the pull rope being slid and pulled, the other end of the pull rope pulls the rotating shaft on the cleaning rod 36 to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod 36 to rotate. The rod 36 rotates, and the cleaning rod 36 moves to the side away from the cleaning groove 35. After the cleaning rod 36 rotates, it contacts the inner wall of the water tank 1. When the impeller blade 34 rotates, it drives the support arm 33 to rotate. The rotation of the support arm 33 drives the cleaning rod 36 to rotate. During the rotation of the cleaning rod 36, the inner wall of the water tank 1 is cleaned, and impurities attached to the inner wall of the water tank 1 are cleaned off to prevent the impurities from attaching to the inner wall of the water tank 1 to form scale. Under the stirring action of the support arm 33 and the impeller blade 34, the impurities in the water tank 1 are not easy to attach to the inner wall of the water tank 1.

[0049] The rotation drives the rotating gear 352 in the power chamber 351 to rotate. Since the rotating gear 352 is an incomplete gear, when the slider 38 moves to the end of the sliding groove 37, the rotating gear 352 is freed from the restraint of the teeth, and then the rotating gear 352 is reset under the action of the torsion spring. During the reset process, the rotating gear 352 drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod 36 to reset. The cleaning rod 36 rotates to one side of the cleaning groove 35, thereby realizing multiple intermittent cleaning of the inner wall of the water tank 1;

[0050] When it is necessary to stop the water supply, when the controller controls the pump assembly device 2 to be closed, the controller controls the electromagnetic spring in the movable groove 39 to be energized, and the electromagnetic spring is energized to contract. During the contraction process, the electromagnetic spring drives the fixed ring 32 to move, and the fixed rings 32 on both sides move along the movable groove 39 to the side away from the water inlet 11 and the water outlet 12 respectively. Then the controller controls the pump assembly device 2 to be closed. At this time, the staggered impeller blades 34 are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, and the water hammer impacts the impeller blades 34. The staggered impeller blades 34 disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump assembly device 2 and protecting the pump assembly device 2.

[0051] The cleaned impurities are transported to the water outlet 12 under the action of the water flow. During the transportation process, the impurities encounter the filter screen provided in the water outlet 12, and the impurities are then filtered by the filter screen.

[0052] As a specific implementation of the present invention, a battery (not shown in the figure) is arranged between the water tank 1 and the pump assembly 2.

[0053] As a specific embodiment of the present invention, a heat-to-electricity device is provided in the pump assembly 2, a vibration generator is also provided in the pump assembly 2, the heat-to-electricity device is electrically connected to a battery, the battery is electrically connected to the vibration generator, and a vibration frequency sensor is provided in the pump assembly 2;

[0054] During the rotation of the cleaning device 3, the magnetic flux lines are cut in the electromagnetic coil, so that the electromagnetic coil generates magnetic force, thereby generating electricity, and the electricity is then transmitted to the battery through the circuit for storage. The pump assembly 2 is started under the control of the controller, and the water pump in the pump assembly 2 generates heat during operation, and the heat is accumulated in the pump assembly 2. The heat-to-electric device (application number: CN201380055376.6, which discloses a thermoelectric converter) is then started under the control of the controller, and the heat-to-electric device immediately converts the heat in the pump assembly 2 into electrical energy, which is also transmitted to the battery through the circuit for storage. After the heat-to-electric device converts the heat in the pump assembly 2, it not only achieves heat dissipation in the pump assembly 2, but also makes use of the heat energy.

[0055] Since the water pump generates noise during its operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump group device 2 to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation and achieving the purpose of noise reduction.

[0056] Working principle of the present invention:

[0057] The staff controls the water inlet 11 to be opened through the controller, and then the water is transported to the water tank 1 through the water inlet 11 for storage. When the water consumption increases, the controller controls the pump unit 2 to start and the water outlet 12 to be opened, and the water pump in the pump unit 2 draws the water in the water tank 1. The water in the water tank 1 is then transported to the water pump in the pump unit 2 through the water outlet 12, and the water pump draws the water into the pipe system, thereby realizing the water supply of the pipe.

[0058] When the controller controls the pump assembly device 2 to start, the water in the water tank 1 is immediately transported to the pipeline under the action of the water pump, and the water in the water tank 1 moves from one side of the water inlet 11 to the water outlet 12. During the water transport process in the water tank 1, the water flow impacts the impeller blade 34, and the impeller blade 34 immediately generates a rotational force under the action of the water flow, and the impeller blade 34 immediately rotates. During the rotation of the impeller blade 34, the impeller blade 34 drives the support arm 33 to rotate, and the rotation of the support arm 33 drives the fixed ring 32 to rotate. When the fixed ring 32 rotates, the fixed ring 32 drives the rotating shaft 31 to rotate;

[0059] Since the support arm 33 is a magnetic conductor, during the rotation of the support arm 33, the support arm 33 continuously cuts the magnetic flux lines in the electromagnetic coil disposed inside the water tank 1, so that the electromagnetic coil generates magnetic force, and then magnetism generates electricity. The electricity generated by the electromagnetic coil is transmitted to the battery through the circuit for storage;

[0060] During the rotation of the support arm 33, the slider 38 moves under the action of centrifugal force, and the slider 38 moves along the sliding groove 37 to the side away from the fixed ring 32. Since the electromagnetic coil generates magnetic force during the rotation of the support arm 33, the magnetic force also attracts the slider 38 to move to the side close to the inner wall of the water tank 1. During the movement of the slider 38, the slider 38 drives the pull rope to move, and the pull rope is pulled immediately. During the process of the pull rope being slid and pulled, the other end of the pull rope pulls the rotating shaft on the cleaning rod 36 to rotate. During the rotation of the rotating shaft, the rotating shaft drives the cleaning rod 36 to rotate. The rod 36 rotates, and the cleaning rod 36 moves to the side away from the cleaning groove 35. After the cleaning rod 36 rotates, it contacts the inner wall of the water tank 1. When the impeller blade 34 rotates, it drives the support arm 33 to rotate. The rotation of the support arm 33 drives the cleaning rod 36 to rotate. During the rotation of the cleaning rod 36, the inner wall of the water tank 1 is cleaned, and impurities attached to the inner wall of the water tank 1 are cleaned off to prevent the impurities from attaching to the inner wall of the water tank 1 to form scale. Under the stirring action of the support arm 33 and the impeller blade 34, the impurities in the water tank 1 are not easy to attach to the inner wall of the water tank 1.

[0061] The rotation drives the rotating gear 352 in the power chamber 351 to rotate. Since the rotating gear 352 is an incomplete gear, when the slider 38 moves to the end of the sliding groove 37, the rotating gear 352 is freed from the restraint of the teeth, and then the rotating gear 352 is reset under the action of the torsion spring. During the reset process, the rotating gear 352 drives the rotating shaft to reset, and the rotating shaft drives the cleaning rod 36 to reset. The cleaning rod 36 rotates to one side of the cleaning groove 35, thereby realizing multiple intermittent cleaning of the inner wall of the water tank 1;

[0062] When it is necessary to stop the water supply, when the controller controls the pump assembly device 2 to be closed, the controller controls the electromagnetic spring in the movable groove 39 to be energized, and the electromagnetic spring is energized to contract. During the contraction process, the electromagnetic spring drives the fixed ring 32 to move, and the fixed rings 32 on both sides move along the movable groove 39 to the side away from the water inlet 11 and the water outlet 12 respectively. Then the controller controls the pump assembly device 2 to be closed. At this time, the staggered impeller blades 34 are combined into an impeller as a whole. After the valve is closed, water forms a water hammer, and the water hammer impacts the impeller blades 34. The staggered impeller blades 34 disperse the impact of the water hammer, thereby reducing the impact of the water hammer on the pump assembly device 2 and protecting the pump assembly device 2.

[0063] The cleaned impurities are transported to the water outlet 12 under the action of the water flow. During the transportation process, the impurities encounter the filter screen provided in the water outlet 12, and the impurities are then filtered by the filter screen.

[0064] During the rotation of the cleaning device 3, the magnetic flux lines are cut in the electromagnetic coil, so that the electromagnetic coil generates magnetic force, thereby generating electricity, which is then transmitted to the battery through the circuit for storage. The pump assembly 2 is started under the control of the controller, and the water pump in the pump assembly 2 generates heat during operation, and the heat is accumulated in the pump assembly 2. The heat-to-electric device is then started under the control of the controller, and the heat-to-electric device then converts the heat in the pump assembly 2 into electrical energy, which is also transmitted to the battery through the circuit for storage. After the heat-to-electric device converts the heat in the pump assembly 2, it not only achieves heat dissipation in the pump assembly 2, but also makes use of the heat energy.

[0065] Since the water pump generates noise during its operation, the vibration frequency sensor converts the vibration frequency signal generated by the noise into an electrical signal and transmits it to the controller, which then analyzes it. The controller then controls the vibration generator in the pump group device 2 to start, and the battery then transmits the stored electrical energy to the vibration generator through the circuit. The controller controls the vibration generator to generate a relative vibration frequency based on the vibration frequency received by the vibration frequency sensor, so that the vibration frequency of the noise and the vibration frequency generated by the vibration generator cancel each other out, thereby achieving noise attenuation and achieving the purpose of noise reduction.
