Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, and more specifically, to a drainage pump operation monitoring device for water conservancy construction. Background Art

[0002] Water conservancy construction is a project built to eliminate water disasters and develop and utilize water resources. During the water conservancy construction process, it is necessary to automatically control the water level and water volume so that the water level at the water conservancy construction site can be at the set position, thus requiring a drainage pump to drain water for water level control.

[0003] The drainage pump mainly includes a water inlet, a water outlet and driving blades that generate water flow between the inlet and the outlet. When the water quality enters the pump directly without being well treated, the impurities mixed in the water flow will have an adverse effect on the working condition and performance of the pump itself and even the entire water circulation system.

[0004] The utility model patent with patent publication number CN208281205U discloses a drainage pump safety monitoring device, including a detector, the left and right sides of the detector are fixedly installed with clamps, the opposite sides of the two clamps are fixedly installed with spring plates, the opposite sides of the two spring plates are fixedly installed with first springs, the opposite sides of the two first springs are movably connected with movable columns, the opposite sides of the two movable columns are fixedly installed with connecting columns, and the opposite sides of the two connecting columns are fixedly installed with push plates. The drainage pump safety monitoring device, through the coordinated use of the detector, clamps, spring plates, first springs, movable columns, connecting columns and push plates, by pushing the movable columns, the slider drives the movable columns to move on the guide rail, squeezes the detector, makes the detector more stable, and can apply a certain buffer force through the action of the first spring to increase the shock absorption effect.

[0005] However, in actual use, this structure can only perform performance tests on drainage pumps that are not in working condition, but cannot perform operation tests on drainage pumps that are running in water conservancy projects, and thus cannot detect the operating status of running drainage pumps. Therefore, a drainage pump operation monitoring device for water conservancy construction is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a drainage pump operation monitoring device for water conservancy construction to solve the problems raised in the above-mentioned background technology.

During the rotation of the turntable, the reflector on the turntable rotates in a circle at the bottom of the speed sensor. The speed of the turntable is determined by the number of times the reflector passes per unit time and is displayed on the display. In this way, the drainage volume per unit time can be monitored in real time. When the operating power of the drain pump remains unchanged, if the turntable speed decreases too much and continues to be at a low speed, it can be determined that the drain pump is operating abnormally, and the internal part of the drain pump can be inspected and repaired in time to see if there are any abnormalities such as blockage.

During the rotation of the turntable 506, the reflective sheet 507 on the turntable 506 rotates in a circle at the bottom of the speed sensor 703. The speed of the turntable 506 is determined by the number of times the reflective sheet 507 passes per unit time, and is displayed on the display table 702. In this way, the drainage volume per unit time can be monitored in real time. When the speed of the turntable 506 decreases too much and continues to be at a relatively low speed while the operating power of the drainage pump remains unchanged, it can be determined that the drainage pump is operating abnormally, and the interior of the drainage pump can be inspected and repaired in time to see if there are any abnormalities such as blockage.

[0032] As attached Figure 2 and Figure 3 As shown, the transmission mechanism 5 includes a transmission shaft 501 , which is rotatably mounted on the fixed plate 8 , and the transmission shaft 501 is coaxially arranged with the monitoring tube 4 .

[0033] Impeller 502 , which is mounted at one end of transmission shaft 501 .

[0034] The transmission gear 503 is installed at the other end of the transmission shaft 501 .

[0035] The follower gear 504 is meshed and connected with the transmission gear 503 .

[0036] The follower rod 505 is inserted into the shaft seal, and the bottom end of the follower rod 505 is coaxially connected with the follower gear 504 .

[0037] The turntable 506 is installed on the top of the follower rod 505 and is located in the top box 6.

[0039] A cylindrical inner cavity is provided inside the top box 6 , a through hole is provided at the bottom end of the cylindrical inner cavity, and the turntable 506 is located inside the cylindrical inner cavity. The top end of the follower rod 505 passes through the through hole and is connected to the bottom end of the turntable 506 .

[0040] The impeller 502 is impacted by the drainage, so that during the rotation of the impeller 502, the transmission shaft 501 can be driven to rotate, so that the transmission gear 503 engages with the follower gear 504 to rotate, so that the follower rod 505 rotates, the turntable 506 rotates in the top box 6, and the reflective sheet 507 rotates with the turntable 506, so that the monitoring component 7 can detect the number of times the reflective sheet 507 passes per unit time, so as to accurately determine the rotation speed of the turntable 506.

[0045] Working principle of the utility model: when the drainage pump operation monitoring device for water conservancy construction is used to monitor the operation status of the drainage pump in real time, the monitoring tube 4 is installed on the drainage pipe 2 connected to the drainage pump. During the operation of the drainage pump, the water discharged from the drainage pipe 2 impacts the impeller 502, so that the impeller 502 drives the transmission shaft 501 to rotate, so that the follower gear 504 is meshed with the transmission gear 503, so that the follower rod 505 rotates synchronously with the turntable 506. During the rotation of the turntable 506, the reflective sheet 507 on the turntable 506 rotates in a circle at the bottom of the speed sensor 703. The speed of the turntable 506 is determined by the number of times the reflective sheet 507 passes in a unit time, and is displayed on the display table 702. In this way, the drainage volume per unit time can be monitored in real time. When the speed of the turntable 506 is reduced too much and is continuously at a relatively low speed under the condition that the operating power of the drainage pump remains unchanged, it can be judged that the operation of the drainage pump is abnormal, and the inside of the drainage pump can be inspected and repaired in time to see if there are abnormalities such as blockage.

[0046] The utility model utilizes the impact force generated by the drainage volume of the drainage pump under the same power to impact the impeller 502, so that the turntable 506 rotates, and the rotation speed of the turntable 506 is monitored. By monitoring the change in the rotation speed of the turntable 506 under the same power, whether the operation of the drainage pump is normal is monitored, and the operation of the drainage pump in a running state can be monitored in real time.
