Description

Technical Field

[0001] This invention relates to the field of water pump control technology, and more specifically to a water pump control box based on the Industrial Internet. Background Technology

[0002] Pump control boxes are mainly used for automatic control of pumps in various occasions such as water supply, drainage, fire protection, sprinkler network pressurization, and HVAC hot and cold water circulation in industrial and agricultural production and various buildings.

[0003] For example, Chinese patent CN207795604U proposes a water pump control box. By setting a fixed bracket including a housing fixing arm and a support body, the two ends of the housing fixing arm are fixed to the top and bottom ends of the support body, respectively. The arm of the housing fixing arm is fixed to the back of the rectangular box of the water pump control box, and the bottom end of the support body contacts the mounting surface of the rectangular box on which the water pump control box is installed. This allows the rectangular box to be placed on the mounting surface so that the rectangular box stands stably, thus avoiding the technical problems of inconvenience in moving and low waterproof and dustproof performance caused by directly placing the rectangular box on the mounting surface.

[0004] The above structure can only control one set of water pumps. When a malfunction occurs, it cannot continue to be used. If water cannot be supplied in time, it will cause other problems and is not conducive to practical use. At the same time, no heat dissipation structure is involved. A large amount of heat will accumulate inside the box, which will accelerate the aging rate of the internal components of the water pump control box and reduce the service life of the water pump control box.

[0005] Based on this, the present invention designs a water pump control box based on the Industrial Internet to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water pump control box based on the Industrial Internet.

[0009] Furthermore, the adjustable flow guide assembly includes a flow guide plate, a connecting rope, a horizontal shaft, a connecting plate, a side support seat, a rotating disk, and a self-locking assembly. Multiple horizontal shafts are rotatably installed on the inner wall of the first through hole at equal intervals from top to bottom. The flow guide plate is fixedly connected to the horizontal shaft one by one. The rear side of the inner end of the flow guide plate is rotatably connected to the connecting plate. The outer end of the uppermost flow guide plate is connected to the bottom of the connecting rope. The top of the connecting rope passes through the air distribution assembly and is fixedly connected to the rotating disk. The connecting shaft of the rotating disk is rotatably connected to the side support seat. The side support seat is fixedly connected to the outer wall of the box. The outer end of the connecting shaft of the rotating disk passes through the side support seat and is fixedly connected to the self-locking assembly.

[0010] Furthermore, the distance from the horizontal axis to the outer end of the guide plate is greater than the distance from the horizontal axis to the inner end of the guide plate.

[0011] Furthermore, the self-locking assembly includes a ratchet and a pawl, with the rotating disk connecting shaft fixedly connected to the ratchet that engages with the pawl, and the pawl rotatably connected to the side support.

[0012] Furthermore, the air distribution assembly includes a first outer cover, a side air outlet, and a fan. The first outer cover is fixedly installed on the outer wall of the housing, and the inner end of the first outer cover is open and directly opposite the first through hole. The fan is fixedly installed at the bottom inside the first outer cover. The side air outlet is fixedly installed on the air outlet end of the fan, and the air outlet of the side air outlet is directly opposite the first through hole.

[0014] Furthermore, the bottom dimension of the flared air inlet pipe is more than ten times the size of the fan's input end.

[0015] Beneficial effects: The water level sensor of this invention sends the monitored data to the display panel through the pressure sensor terminal. When the monitored data is lower than the set value, the display panel controls one set of frequency converters. The frequency converters start the corresponding water pumps through the output terminal to pump water, while the other set of frequency converters is in standby mode. When one set of frequency converters or the water pumps connected to it fail, the display panel shuts down one set of frequency converters and starts the other set of frequency converters. The frequency converters start the corresponding water pumps through the output terminal to pump water, realizing one-on-one control of two water pumps, which is conducive to intelligent use. The display panel sends the data from the pressure sensor terminal, the two sets of frequency converters, and the two sets of pumps to the control terminal through the 4G antenna controller and 4G antenna, which can keep track of the specific situation in a timely manner. The control terminal transmits adjustment commands to the display panel through the 4G antenna and 4G antenna controller, and the display panel performs corresponding operations according to the adjustment commands. When the enclosure is in normal use, the self-cleaning heat dissipation component efficiently dissipates heat from the components that generate heat inside the enclosure. In the event of a fire, the self-cleaning heat dissipation component creates negative pressure exhaust, quickly reducing the amount of oxygen, thereby achieving the purpose of extinguishing the fire and providing better protection for the water pump control box.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example 1, please refer to Figure 1 , Figure 2 and Figure 7 A water pump control box based on the Industrial Internet, including a box body 1; The front end of the housing 1 is connected to a door panel 2 via hinges and a mechanical lock; The housing 1 is equipped with a wireless control unit for controlling two water pumps, one in use and one on standby. The wireless control assembly includes a display panel 3, a 4G antenna 4, two sets of frequency converters 6, a 4G antenna controller 7, a pressure sensor terminal block 8, an output terminal block 9, two sets of air circuit breakers 10, and a main switch 11. The display panel 3 is fixedly installed on the door panel 2. The 4G antenna 4 is fixedly installed on the outer wall of the enclosure 1. The two sets of frequency converters 6 are symmetrically fixedly installed on the upper part of the inner wall of the enclosure 1. The 4G antenna controller 7, pressure sensor terminal block 8, output terminal block 9, two sets of air circuit breakers 10, and the main switch 11 are all fixedly installed on the inner wall of the enclosure 1, located below the frequency converters 6. The main switch 11 is connected to the municipal... The main switch 11 is connected to the input terminals of two sets of air circuit breakers 10. The output terminals of one set of air circuit breakers 10 are connected to the input terminals of one set of frequency converters 6. The output terminals of the other set of air circuit breakers 10 are connected to the input terminals of the other set of frequency converters 6. The output terminals of the two sets of frequency converters 6 are connected to the input terminals of the output terminals 9. The output terminals of the output terminals 9 are electrically connected to the two sets of water pumps respectively. The input terminal of the pressure sensor terminal 8 is connected to the water level sensor. The frequency converters 6, the 4G antenna controller 7, and the pressure sensor terminal 8 are all electrically connected to the display panel 3. The side wall of the enclosure 1 is connected to a self-cleaning heat dissipation component 5 for heat dissipation and negative pressure exhaust. The air outlet of the self-cleaning heat dissipation component 5 is directly opposite the heat-generating components inside the enclosure 1.

[0022] The 4G antenna 4 connects to an external control terminal via a wireless network to achieve industrial internet connectivity; The water level sensor transmits the monitored data to the display panel 3 via the pressure sensor terminal 8. When the monitored data is lower than the set value, the display panel 3 controls one set of frequency converters 6. The frequency converters 6 start the corresponding water pumps to pump water via the output terminal 9. The other set of frequency converters 6 is in standby mode. If one set of frequency converters 6 or the water pump connected to it fails, the display panel 3 shuts down one set of frequency converters 6 and starts the other set of frequency converters 6. The frequency converters 6 start the corresponding water pumps to pump water via the output terminal 9. This achieves one-on-one control of the two water pumps, which is conducive to intelligent use. The display panel 3 transmits the data from the pressure sensor terminal 8, the two sets of frequency converters 6, and the two sets of pumps to the control terminal via the 4G antenna controller 7 and the 4G antenna 4, which can keep track of the specific situation in a timely manner. The control terminal transmits adjustment commands to the display panel 3 via the 4G antenna 4 and the 4G antenna controller 7, and the display panel 3 performs corresponding operations according to the adjustment commands. When the enclosure 1 is in normal use, the self-cleaning heat dissipation component 5 efficiently dissipates heat from the heat-generating components inside the enclosure 1. When the enclosure 1 is on fire, the self-cleaning heat dissipation component 5 performs negative pressure exhaust to quickly reduce the amount of oxygen, thereby achieving the purpose of extinguishing the fire and providing better protection for the water pump control box. Adjustment commands include, but are not limited to, adjusting power and adjusting water level settings; Example 2, based on Example 1, please refer to... Figures 2-10 The self-cleaning heat dissipation component 5 includes a self-cleaning dust filter component, an air distribution component, an adjustable flow guide component, and a self-sealing air outlet component. The two side walls of the housing 1 are respectively provided with a first through hole 57 and a second through hole 514. The self-sealing air outlet component is fixedly installed on the outside of the second through hole 514 of the housing 1. The adjustable flow guide component is installed in the first through hole 57. The air distribution component is fixedly installed on the outside of the first through hole 57 of the housing 1. The self-cleaning dust filter component is fixedly installed at the air inlet end of the air distribution component. An isolation net 515 for preventing animals from entering is fixedly connected to the inner wall of the box 1 at the second through hole 514; The adjustable flow guide assembly includes a flow guide plate 58, a connecting rope 511, a horizontal shaft 512, a connecting plate 513, a side support seat 516, a rotating disk 518, and a self-locking assembly. Multiple sets of horizontal shafts 512 are rotatably installed on the inner wall of the first through hole 57 at equal intervals from top to bottom. The flow guide plate 58 is fixedly connected to the horizontal shaft 512 one by one. The rear side of the inner end of the flow guide plate 58 is rotatably connected to the connecting plate 513. The outer end of the uppermost flow guide plate 58 is connected to the bottom of the connecting rope 511. The top of the connecting rope 511 passes through the air distribution assembly and is fixedly connected to the rotating disk 518. The connecting shaft of the rotating disk 518 is rotatably connected to the side support seat 516. The side support seat 516 is fixedly connected to the outer wall of the housing 1. The outer end of the connecting shaft of the rotating disk 518 passes through the side support seat 516 and is fixedly connected to the self-locking assembly. The distance from the horizontal axis 512 to the outer end of the guide plate 58 is greater than the distance from the horizontal axis 512 to the inner end of the guide plate 58; Since the distance from the horizontal axis 512 to the outer end of the guide plate 58 is greater than the distance from the horizontal axis 512 to the inner end of the guide plate 58, the gravity at the part from the outer end of the guide plate 58 to the horizontal axis 512 is greater than the gravity at the part from the inner end of the guide plate 58 to the horizontal axis 512. Under natural conditions, the inner end of the guide plate 58 is higher than the outer end of the guide plate 58. Then, the process of pulling the connecting rope 511 upward causes the inner end of the guide plate 58 to rotate lower than the outer end of the guide plate 58, so that the guide plate 58 can be adjusted to a greater angle. The self-locking assembly includes a ratchet 519 and a pawl 520. The rotating disk 518 is fixedly connected to the ratchet 519, which is used in conjunction with the pawl 520. The pawl 520 is rotatably connected to the side support 516. A hexagonal nut for driving the ratchet 519 to rotate is fixedly connected to the outer end of the ratchet 519; The air distribution assembly includes a first outer cover 51, a side air outlet 59, and a fan 510. The first outer cover 51 is fixedly installed on the outer wall of the housing 1. The inner end of the first outer cover 51 is open and directly faces the first through hole 57. The fan 510 is fixedly installed at the bottom inside the first outer cover 51. The side air outlet 59 is fixedly installed on the air outlet end of the fan 510. The air outlet of the side air outlet 59 is directly facing the first through hole 57. The self-cleaning filter assembly is connected to the input end of the fan 510. The fan 510 is a forward and reverse rotating fan. The connecting rope 511 passes through the top of the first outer cover 51 and is then fixedly connected to the rotating disk 518. The top of the side air outlet 59 is flush with the uppermost horizontal axis 512; The self-cleaning filter assembly includes a flared air inlet pipe 53, a filter plate 56, a ball bearing 517, a slide rod 521, a spring 522, an impeller 523, a rotating shaft 524, a synchronous belt assembly 525, a rotating seat 526, and a second horizontal shaft 527. The flared air inlet pipe 53 is fixedly installed at the input end of the fan 510. The spring 522 is symmetrically fixedly installed on the flared air inlet pipe 53. The bottom of the spring 522 is fixedly connected to the slide rod 521, and the upper end of the slide rod 521 is slidably connected to the sliding hole opened in the flared air inlet pipe 53. The filter plate 56 is connected to the slide rod 523 by a fixing component. Rod 521 is fixedly connected, rotating shaft 524 is rotatably connected to the inner wall of the input end of fan 510 through bearings, impeller 523 and a set of synchronous pulleys of synchronous belt assembly 525 are fixedly connected to rotating shaft 524, second horizontal shaft 527 is rotatably connected to the inner wall of flared air inlet pipe 53 through bearings, second horizontal shaft 527 is fixedly connected to another set of synchronous pulleys of synchronous belt assembly 525, second horizontal shaft 527 is fixedly connected to rotating seat 526, two sets of ball bearings 517 are rotatably installed on the outer end of rotating seat 526, and ball bearings 517 are movably connected to the top of filter plate 56; The fastener is a nut, and the bottom of the slide rod 521 is connected to the nut through a threaded groove. The nut is in close contact with the filter plate 56. The bottom dimension of the flared air inlet pipe 53 is more than ten times the size of the input end of the fan 510; When the filter plate 56 is filtering, the air intake volume of the flared air inlet pipe 53 meets the requirements of the fan 510. The self-sealing vent assembly includes a second outer cover 52, a torsion spring hinge 54, and a baffle 55. The second outer cover 52 is fixedly installed on the outer wall of the housing 1, and the bottom of the second outer cover 52 is open. The side opening of the second outer cover 52 is directly opposite the second through hole 514. The torsion spring hinge 54 is fixedly installed at the bottom of the outer end of the second outer cover 52. The torsion spring hinge 54 is fixedly connected to the baffle 55. When the baffle 55 is in contact with the second outer cover 52, the restoring force of the torsion spring hinge 54 is the same as the weight of the baffle 55.

[0023] Based on the location of the heat-generating internal components, the ratchet 519 of the self-locking assembly is rotated. The ratchet 519 drives the rotating disk 518 to rotate, which in turn drives the connecting rope 511 to pull. The connecting rope 511 pulls the uppermost guide plate 58 to rotate along the uppermost horizontal axis 512. The uppermost guide plate 58 drives the other guide plates 58 to rotate synchronously along the other horizontal axes 512 through the connecting plate 513. The air guiding direction of the guide plate 58 is adjusted to face the location of the heat-generating internal components in the housing 1, which helps the heat-generating components in the housing 1 to dissipate heat efficiently and extends the service life of the housing 1. After adjustment, the pawl 520 locks the ratchet 519 to ensure stability after adjustment. During normal heat dissipation, the fan 510 of the air distribution assembly rotates forward. The fan 510 draws air into the flared air inlet pipe 53, where it is filtered by the filter plate 56. The filtered air is then evenly distributed to the outer end of the guide plate 58 through the side air outlet pipe 59, and then guided into the housing 1 for heat dissipation. The increased air pressure inside the housing 1 pushes the baffle 55 of the self-sealing air outlet assembly to open the second outer cover 52 along the torsion spring hinge 54, allowing hot air to be discharged from the bottom of the second outer cover 52, thus achieving heat dissipation for the housing 1. The air flowing inside the fan 510 drives the impeller 523 to rotate, which in turn drives the rotating shaft 524 to rotate. The rotating shaft 524 rotates the second horizontal shaft 527 via the synchronous belt assembly 525. The second horizontal shaft 527 drives the rotating seat 526 to rotate, and the rotating seat 526 drives the ball bearing 517 to rotate. After the ball bearing 517 contacts the filter plate 56, it pushes the filter plate 56 to move downward. The filter plate 56 drives the bottom of the slide rod 521 and the spring 522 to move downward. The spring 522 is in a stretched state. After the ball bearing 517 separates from the filter plate 56, the spring 522 drives the filter plate 56 to move upward via the slide rod 521, realizing the up and down shaking of the filter plate 56. This facilitates the shedding of particles adhering to the bottom of the filter plate 56, realizes the self-cleaning of the filter plate 56, and ensures the filtration performance of the filter plate 56. When a fire occurs inside the housing 1, the fan 510 reverses, and the restoring force of the torsion spring hinge 54 drives the baffle 55 to seal the bottom of the second outer cover 52, preventing air from entering the housing 1 from the bottom of the second outer cover 52. The fan 510 draws the air from the housing 1 through the side air outlet 59 and distributes it through the flared air inlet pipe 53, drawing the housing 1 into a negative pressure state, quickly reducing the amount of oxygen, thereby achieving the purpose of extinguishing the fire.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
