Description

Technical Field

[0001] The utility model belongs to the technical field of data acquisition devices, and in particular relates to a data acquisition device for an axial flow water pump in a tidal environment. Background Art

[0002] Tides are a common natural phenomenon in coastal waterways like the Qiantang River, significantly impacting water levels, flow rates, and water quality. Under these circumstances, traditional operating plans for open-type vertical-shaft axial-flow pumps fail to consider more optimized operating models and rely excessively on empirical judgments, failing to achieve optimal performance. This results in energy waste and unit losses. Consequently, empirical judgments are less accurate than actual data collection. Existing technologies typically use monitoring equipment equipped with vibration sensors to monitor the pump's vibration frequency and amplitude, generating data to determine whether the pump's operating conditions are abnormal.

[0003] Patent No. CN216342867U discloses a data acquisition device for monitoring water pump vibration, comprising a protective shell installed on the casing of the water pump by fastening bolts, the protective shell comprising an upper shell with an opening on the lower end face and a lower shell with an opening on the upper end face, the lower shell being provided with a collection device body for collecting water pump vibration data; the lower shell is inserted into the upper shell along the opening on the lower end face of the upper shell, and a first extension plate is provided on the lower end peripheral side wall of the upper shell, and a second extension plate is provided on the lower end peripheral side face of the lower shell that overlaps with the first extension plate above and below, the first extension plate and the second extension plate are connected by multiple screws, and a sealing ring is also embedded in the upper end face of the second extension plate to seal the inside of the protective shell; the data acquisition device for monitoring water pump vibration of the utility model has a detachable sealing structure in which the protective shell is penetrated from the bottom of the upper shell, and rainwater cannot penetrate into the shell, which is suitable for outdoor environments where water pumps work.

[0004] In the prior art, a protective shell, a first extension plate, and a second extension plate are provided to protect the collection device and prevent rain from soaking the device, thereby increasing its service life. However, the following problems still exist in the overall use. In the prior art, the soil in a tidal environment is relatively loose, and the water pump is prone to tilt. When collecting data from the water pump in this environment, the collection device will cause data anomalies due to the angle of the water pump; secondly, the water level of the tide is uncertain, and when local water needs to be pumped out, it is sometimes necessary to wait for high tide, which makes pumping difficult. Utility Model Content

By arranging a support frame and a pressure sensor, when the transmission rod is damaged and tilted, the rubber ring on one side will be squeezed. After the rubber ring is squeezed and deformed, it will squeeze the pressure sensor, so that the pressure sensor sends the received pressure information to the control terminal, and the state of the transmission rod can be intuitively observed through the control terminal.

[0027] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 , a data acquisition device for an axial flow water pump in a tidal environment, comprising a water pump 10, the water pump 10 is provided with a fixed frame 11 outside, the bottom of the fixed frame 11 is provided with a plurality of support columns 12, the outer circular surface of the bottom of the plurality of support columns 12 is provided with a plurality of booster plates 13 which can be opened and closed, the inside of the plurality of support columns 12 is rotatably provided with a drive rod 14, one end of the plurality of drive rods 14 is provided with a drive handle 15, the bottom inlet of the water pump 10 is provided with a horn mouth 16, the bottom of the horn mouth 16 is provided with a filter screen 17, the outer circular surface of the water pump 10 is symmetrically provided with two lifting frames 18, one of the lifting frames 18 is rotatably provided with a threaded rod 19 inside, the other lifting frame 18 is provided with an auxiliary rod 20 inside, the inside of the water pump 10 is provided with a support frame 40, the inside of the support frame 40 is slidably provided with a pressure sensor 43.

[0028] In the scheme, the inside of the fixed frame 11 is provided with a notch 22, and the water pump 10 can pass through the notch 22 during installation, and the lifting frame 18 is respectively installed on the outside of the threaded rod 19 and the auxiliary rod 20, one of which is in threaded transmission connection with the threaded rod 19, and after the threaded rod 19 rotates, the lifting frame 18 will move up and down on the surface of the threaded rod 19; the lifting frame 18 can also abut on the end face of the fixed frame 11, and a plurality of threaded holes are arranged on the end face of the lifting frame 18, and when the water pump 10 does not need to be lifted, the lifting frame 18 can be fixed on the end face of the fixed frame 11 through the cooperation of the threaded holes and the bolts, so as to better carry out the water diversion work; the support column 12 is installed at the corner of the fixed frame 11 in a rectangular shape, and the support column 12 can support the fixed frame 11, so that the water pump 10 can be more stable; the horn 16 can optimize the water flow entering path, significantly reduce the resistance, and improve the water diversion efficiency of the water pump 10; there are more silt and branches in the tidal environment, and the filter screen 17 can block most of the impurities to prevent large impurities from damaging the water pump 10, thereby improving the service life of the water pump 10; the driving rod 14 extends from the inside of the support column 12 to the top end of the support column 12 and extends through the fixed frame 11, and the extension end of the driving rod 14 is connected with the driving handle 15.

[0029] Reference Figure 2 , Figure 3 and Figure 4 , the outside of the plurality of driving rods 14 is provided with a first bearing 23 on the inner wall of the support column 12, the outside of the driving rod 14 is slidingly provided with a moving block 24, a plurality of connecting pieces 25 are arranged on the bottom end face of the moving block 24, one end of the connecting piece 25 is rotatably provided with a connecting rod 26, the other end of the connecting rod 26 is rotatably connected with the booster plate 13, the booster plate 13 is rotatably connected with the inner bottom of the support column 12, a plurality of extension holes 27 are arranged on the bottom of the support column 12, the extension holes 27 are correspondingly arranged with the booster plate 13, and a sharp end 28 is arranged below the extension holes 27 on the bottom end face of the support column 12.

[0030] In this solution, the first bearing 23 can prevent the driving rod 14 from tilting when rotating. The first bearing 23 can limit the driving rod 14 while allowing the driving rod 14 to rotate independently, reducing the friction between the support column 12 and the driving rod 14, thereby improving the transmission effect; the extension hole 27 is the same shape and size as the supercharged plate 13, and the supercharged plate 13 will engage with the extension hole 27 when it is retracted into the interior of the support column 12. This setting can make the bottom of the support column 12 more flat, thereby facilitating the bottom of the support column 12 to enter the mud The end face of the boost plate 13 and the inner bottom of the support column 12 are both provided with rotating connecting parts, so that the boost plate 13 can be flipped on the inner bottom of the support column 12. After the boost plate 13 is flipped, the contact area with the soil can be increased, thereby improving the stability of the support column 12; the driving rod 14 and the inner bottom of the support column 12 are rotatably connected. This setting can reduce the friction between the driving rod 14 and the support column 12, and improve the transmission effect of the driving rod 14; the protrusion of the tip 28 can better break the soil, thereby more conveniently fixing the support column 12.

[0031] refer to Figure 2 、 Figure 5 and Figure 6 A rubber ring 41 is provided inside the support frame 40, and a slide groove 42 is provided on one side of the rubber ring 41 inside the support frame 40. The inside of the slide groove 42 is slidably connected to the pressure sensor 43, and a telescopic rod 44 is provided on one side of the pressure sensor 43.

[0032] In this solution, the rubber ring 41 is provided to prevent the pressure sensor 43 from directly contacting the transmission rod 32. The transmission rod 32 will vibrate at a high frequency when rotating. The rubber ring 41 can not only cushion the pressure sensor 43, but also seal the chute 42 to prevent water from entering the chute 42 and avoid malfunction of the pressure sensor 43 due to long-term immersion. One end of the telescopic rod 44 abuts against one side of the pressure sensor 43. This setting allows the pressure sensor 43 to return to its original position after being pushed by the rubber ring 41, so that the pressure sensor 43 is always abutted against one side of the rubber ring 41, thereby better collecting data from the transmission rod 32.

[0033] refer to Figure 1 and Figure 2 A data terminal 29 is provided on the end surface of the fixing frame 11 . An ultrasonic flow meter 30 is provided on one side of the data terminal 29 outside the water pump 10 . A water pressure sensor 39 is provided at the outlet of the water pump 10 .

[0034] In this solution, the data terminal 29 is an existing technology. Its main function is to monitor the equipment status in real time through data analysis. Once an abnormality is found, the early warning mechanism is immediately triggered, and the operation and maintenance personnel are notified in time to handle it, effectively preventing accidents. The collected data and analysis results are presented in charts, images and other easy-to-understand formats through the display screen of the data terminal 29. The collected data is analyzed and judged by the analysis technology and learning algorithms within the device to find patterns, predict trends, identify abnormalities, etc., and it has a certain degree of machine algorithm autonomous learning function. By setting up an ultrasonic flow meter 30, the flow rate of the water flow can be measured by ultrasound.

[0035] refer to Figure 2 、 Figure 5 and Figure 7 A spindle motor 31 is provided at the top of the water pump 10, and a transmission rod 32 is provided on the output shaft of the spindle motor 31. A guide vane 33 is fixedly provided at one end of the transmission rod 32, and an impeller 34 is provided on the bottom end surface of the guide vane 33. A sealing ring 35 is provided between the transmission rod 32 and the water pump 10, and a second bearing 36 is provided above the sealing ring 35. A filler shell 37 is provided above the second bearing 36, and a pressure plate 38 is provided on the end surface of the filler shell 37.

[0036] In this solution, the sealing ring 35 is made of rubber. By setting the sealing ring 35, the sealing degree between the spindle motor 31 and the water pump 10 can be improved to prevent the upwelling water from penetrating into the transmission structure and affecting the normal use of the spindle motor 31; the interior of the stuffing shell 37 is cavity-shaped, which is used for filling material for shaft sealing. The filling material can fit tightly between the shaft and the inner wall of the stuffing box to prevent fluid leakage and ensure the normal operation of the water pump 10.

[0037] When in use, first bury the bottom of the support column 12 in the soil, and then rotate the driving rod 14 by driving the handle 15, so that the driving rod 14 rotates inside the support column 12. Since the bottom of the moving block 24 is connected to the connecting rod 26, after the driving rod 14 rotates, the moving block 24 slides downward, and at the same time, the moving block 24 drives the bottom connecting piece 25 to push the bottom connecting rod 26, so that the connecting rod 26 pushes the boosting plate 13. Since the connecting rod 26 is rotatably connected to the boosting plate 13, and one end of the boosting plate 13 is rotatably connected to the inner bottom of the support column 12, the boosting plate 13 is flipped after being pushed by the connecting rod 26, so that the boosting plate 13 is flat inside the soil, increasing the contact area between the boosting plate 13 and the soil, thereby increasing the stability of the support column 12.

[0038] When the water pump 10 needs to be lifted, the drive motor 21 is started, and the output shaft of the drive motor 21 drives the threaded rod 19 to rotate, and the threaded rod 19 drives the lifting frame 18 engaged therewith to move upward. When the lifting frame 18 moves upward, it drives the water pump 10 on one side to move upward, thereby adjusting the water pump 10.

[0039] When testing the transmission rod 32, if the transmission rod 32 tilts, it will squeeze the rubber ring 41 on one side. The rubber ring 41 will push the pressure sensor 43 on one side. The pressure sensor 43 will send the collected information to the data terminal 29 after being pressed. The data terminal 29 will issue an alarm and perform maintenance.
