Description

Technical Field

[0001] The utility model relates to the technical field of drainage pumps with water volume measurement, and more specifically, it relates to a drainage pump with water volume measurement. Background Art

[0002] In the existing technology, the design of drainage pumps often focuses on the basic drainage function while neglecting the importance of water volume measurement. As a result, many pump structures are simple and lack the necessary water volume measurement function. This deficiency in design brings many inconveniences in practical applications, especially in scenarios where precise water volume control or data analysis is required.

[0003] First of all, the existing drainage pumps have a simple structure and usually only have the basic drainage function. This design cannot measure the discharged water volume in real time, making it impossible for users to understand the actual drainage situation and accurately control the drainage process according to needs. This lack of transparency of information may affect the rational utilization and management of water resources, especially in situations where water resources are scarce or precise monitoring of emissions is required.

[0004] Secondly, although some devices in the existing technology attempt to solve the water volume measurement problem by adding measurement devices, these devices often have design limitations. For example, the blade curvature inside many measurement devices is fixed, which means they cannot flexibly adjust according to different fluid characteristics and flow rate changes. This fixed structure may lead to inaccurate measurement results under certain conditions, thus affecting users' accurate judgment and decision-making of water volume. In addition, since they cannot be simply adjusted to adapt to different working conditions, these devices may require more frequent maintenance or replacement, which not only increases the maintenance cost but also may affect the normal operation of the equipment.

[0005] In addition, the structures of the existing technology devices are simple, and the sealing performance at the seams of the equipment may not be sufficient. This sealing problem may cause water leakage or other fluid leakage, not only wasting precious water resources but also possibly polluting the environment. In addition, the leakage problem may also lead to a decline in equipment performance and even cause safety accidents. Content of the Utility Model

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a discharge water pump with water volume measurement, having the following beneficial effects:

[0019] 1. The beneficial effect of the measuring device lies in its innovative plug and slot design, as well as the cooperation between the elastic plate and the rotating plate. When the elastic plate is impacted by water flow, it can drive the rotating plate to rotate around the central axis. This design enables the rotational speed of the elastic plate to be measured by an external detector probe, thereby achieving accurate measurement of the flow rate. The limiting effect of the cooperation between the plug and the slot ensures the cooperation relationship between the elastic plate and the rotating plate, preventing the mismatch problem during the deformation of the elastic plate.

[0020] 2. The beneficial effect of the adjustment mechanism is reflected in its ability to adjust the radian of the elastic plate to adapt to different fluid characteristics and flow rate changes. By rotating the driving wheel, the transmission gear and the driven wheel are driven to rotate, and then the movement of the sliding plate is achieved through the cooperation of the lead screw and the slider, thereby squeezing or releasing the elastic plate and changing its radian. This design enables users to adjust the sensitivity of the measuring device according to actual needs, ensuring accurate measurement results under various working conditions.

[0021] 3. The beneficial effect of the sealing mechanism is that it provides effective sealing measures to prevent water leakage. The cooperation between the sealing ring and the sealing groove, as well as the detachable sealing sleeve design, ensure the sealing performance of the device at the seams. Especially the conical structure design of the top sleeve cross-section can compress the sealing ring when inserted into the sealing groove, effectively preventing water leakage during the discharge process, improving the safety and reliability of the equipment. These measures not only ensure the long-term stable operation of the equipment but also reduce the maintenance cost and potential environmental protection risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please refer to Figures 1-5 , a discharge water pump with water volume measurement, including a discharge pump 1, characterized in that: a measuring device is arranged on one side of the discharge pump 1, and the measuring device includes a lower housing 2, an upper cover 3, a central shaft 4, a rotating plate 5, an elastic plate 6, an insertion block 7 and a slot 8. The lower housing 2 is arranged on one side of the discharge pump 1, the upper cover 3 is installed above the lower housing 2, the central shaft 4 is arranged inside the lower housing 2, the rotating plate 5 is rotatably sleeved outside the central shaft 4, the elastic plate 6 is arranged between the two rotating plates 5, the insertion block 7 is fixedly connected to both sides of the elastic plate 6, the slot 8 is opened on the rotating plate 5, and the slot 8 is adapted to the insertion block 7. An adjusting mechanism is arranged inside the lower housing 2, and the adjusting mechanism includes a driving wheel 9, a chute 10, a slider 11, a lead screw 12, a sliding plate 13, a driven wheel 14 and a transmission gear 15. The driving wheel 9 is movably arranged on one side of the transmission gear 15, the chute 10 is opened in the lower housing 2, the slider 11 is fixedly connected to the outside of the sliding plate 13, the slider 11 is movably connected to the lead screw 12 by threads, opposite threads are symmetrically arranged at both ends of the lead screw 12, the driven wheel 14 is fixedly connected to the outside of the lead screw 12, and the driven wheel 14 meshes with the transmission gear 15. The transmission gear 15 is movably installed above the lower housing 2, and a sealing mechanism is arranged above the lower housing 2.

[0032] An installation frame 16 is provided below the discharge pump 1, and the discharge pump 1 is detachably installed above the installation frame 16.

[0033] One end of the discharge pump 1 is connected with an output pipe 17, the other end of the discharge pump 1 is connected with an input pipe 18, and the input end of the discharge pump 1 is connected with the lower shell 2 through the input pipe 18.

[0034] A fixed pipe 19 is connected to the other side of the lower shell 2.

[0035] Bolts 20 are provided on the upper cover 3, threaded holes 21 are opened in the lower shell 2, and the lower shell 2 and the upper cover 3 are detachably connected through the cooperation of the bolts 20 and the threaded holes 21.

[0036] One end of the driving wheel 9 is connected with a rotating rod 22.

[0037] In this embodiment, when it is necessary to adjust the radian of the elastic plate 6, first rotate the sealing sleeve 25 to remove the sealing sleeve 25 from one side of the upper cover 3, then rotate the rotating rod 22, the rotating rod 22 drives the driving wheel 9 to rotate, then the driving wheel 9 drives the transmission gear 15 to rotate, then the transmission gear 15 drives a plurality of driven wheels 14 to rotate together, then the driven wheels 14 drive the respective lead screws 12 to rotate, and then the slider 11 slides along the lead screw 12 in the chute 10. At the same time, the slider 11 drives the sliding plate 13 to move. Since the threads at both ends of the lead screw 12 are symmetrically arranged, the two sliding plates 13 will move inward or outward simultaneously. When the two sliding plates 13 move inward simultaneously, the two sliding plates 13 will push the two rotating plates 5 to move inward, then the two rotating plates 5 will squeeze the elastic plate 6 arranged in the middle, and then the elastic plate 6 will deform, so that the radian of the elastic plate 6 becomes larger. When the two sliding plates 13 move outward simultaneously, the rotating plate 5 is no longer limited by the sliding plate 13, and then the elastic plate 6 is reset and expands outward for reset, and then the elastic plate 6 will push the rotating plates 5 arranged on both sides to move outward. During the deformation process of the elastic plate 6, the insertion block 7 and the slot 8 can well limit the elastic plate 6 to prevent the elastic plate 6 from losing the cooperation relationship with the rotating plate 5. After adjusting the radian of the elastic plate 6 appropriately, stop rotating the rotating rod 22, and then reinstall the sealing sleeve 25 on one side of the upper cover 3.

[0038] Please refer to Figures 1-5 , as an implementation manner of the sealing mechanism: The sealing mechanism includes a sealing ring 23, a sealing groove 24 and a sealing sleeve 25. The sealing rings 23 are respectively installed on one side of the sealing sleeve 25 and the lower shell 2. The sealing groove 24 is opened in the upper cover 3, and the sealing sleeve 25 is detachably installed above the upper cover 3 through threads.

[0039] Top sleeves 26 are connected to both the sealing sleeve 25 and the lower shell 2.

[0040] More specifically, when the device needs to be used, turn on the discharge pump 1. The discharge pump 1 pumps water into the cavity formed inside the lower housing 2 and the upper cover 3 through the input pipe 18 and the fixed pipe 19 connected to one side of the lower housing 2. Then the water flow impacts the elastic plate 6, causing the elastic plate 6 to drive the rotating plate 5 to rotate around the central axis 4 through the insertion block 7 and the slot 8. Then, the rotational speed of the elastic plate 6 is measured by an externally connected detector probe to achieve the measurement of the flow rate. Then the water is pumped into the discharge pump 1 through the input pipe 18 connected to one side of the lower housing 2, and then enters the output pipe 17 connected to the other end of the discharge pump 1, and then flows through the output pipe 17 to an external device for discharge. During use, the top sleeves 26 provided on one side of the lower housing 2 and the top sleeves 26 provided on one side of the sealing sleeve 25 are both designed with a conical cross-section. In this way, when the top sleeve 26 is inserted into the sealing groove 24, the sealing rings 23 provided on both sides are compressed, effectively ensuring the sealing performance at the joint of the device and preventing water leakage.

[0041] In summary, when the overall device is in use or operation: when the arc of the elastic plate 6 needs to be adjusted, first rotate the sealing sleeve 25 to remove the sealing sleeve 25 from one side of the upper cover 3. Then rotate the rotating rod 22, and the rotating rod 22 drives the driving wheel 9 to rotate. Then the driving wheel 9 drives the transmission gear 15 to rotate. Then the transmission gear 15 drives a plurality of driven wheels 14 to rotate together. Then the driven wheels 14 drive the respective lead screws 12 to rotate. Then the slider 11 slides along the lead screw 12 in the sliding groove 10. At the same time, the slider 11 drives the sliding plate 13 to move. Since the threads at both ends of the lead screw 12 are symmetrically arranged, the two sliding plates 13 will move inward or outward simultaneously. When the two sliding plates 13 move inward simultaneously, the two sliding plates 13 will push the two rotating plates 5 to move inward. Then the two rotating plates 5 will squeeze the elastic plate 6 arranged in the middle. Then the elastic plate 6 will deform, causing the arc of the elastic plate 6 to become larger. When the two sliding plates 13 move outward simultaneously, the rotating plate 5 is no longer limited by the sliding plate 13. Then the elastic plate 6 resets and expands outward for reset. Then the elastic plate 6 will push the rotating plates 5 provided on both sides to move outward. During the deformation process of the elastic plate 6, the insertion block 7 and the slot 8 can well limit the elastic plate 6, preventing the elastic plate 6 from losing its cooperation relationship with the rotating plate 5. After the arc of the elastic plate 6 is adjusted appropriately, stop rotating the rotating rod 22, and then reinstall the sealing sleeve 25 on one side of the upper cover 3.

[0042] When the device needs to be used, turn on the discharge pump 1. The discharge pump 1 pumps water into the cavity formed inside the lower housing 2 and the upper cover 3 through the input pipe 18 and the fixed pipe 19 connected to one side of the lower housing 2. Then the water flow impacts the elastic plate 6, causing the elastic plate 6 to drive the rotating plate 5 to rotate around the central axis 4 through the insertion block 7 and the slot 8. Then, the rotational speed of the elastic plate 6 is measured by an external detector probe to achieve the measurement of the flow rate. Then the water is pumped into the discharge pump 1 through the input pipe 18 connected to one side of the lower housing 2, then enters the output pipe 17 connected to the other end of the discharge pump 1, and then flows through the output pipe 17 to an external device for discharge. During use, the top sleeves 26 provided on one side of the lower housing 2 and the top sleeves 26 provided on one side of the sealing sleeve 25 are both designed with a conical cross-section. In this way, when the top sleeve 26 is inserted into the sealing groove 24, the sealing rings 23 provided on both sides are pressed tightly, effectively ensuring the sealing performance at the joint of the device and preventing water leakage.
