Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and more specifically, to an automatic lifting device for water quality monitoring sensors. Background Technology

[0002] To enable online water quality monitoring, water quality sensors can be extended into the water flow to be monitored for real-time online monitoring.

[0003] In practical use, some water quality monitoring sensors adjust their height in the water body via cables. During the cable winding and unwinding process, the cables may become tangled and intertwined inside the winding drum, causing delays or even preventing subsequent cable winding and unwinding, thus affecting the detection efficiency of the water quality monitoring sensor. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic lifting device for water quality monitoring sensors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic lifting device for a water quality monitoring sensor includes a housing. A bracket is fixedly connected to the inner side of the housing. A fixed frame is fixedly connected to one side of the bracket. A limit frame is fixedly connected to the top of the fixed frame. A servo motor is fixedly connected to the top of the fixed frame. A lifting guide mechanism is provided on the outer side of the fixed frame. The lifting guide mechanism includes a cable collector. One side of the cable collector is fixedly connected to the output end of the servo motor. Another side of the cable collector is rotatably connected to the inner side of the limit frame. A synchronous pulley is fixedly connected to one side of the cable collector. A synchronous belt is driven to the outer side of the synchronous pulley, and a synchronous pulley is rotatably connected to the inner side of the synchronous belt. Second, a positioning shell is fixedly connected to the bottom of the fixing frame. Two bearing seats are fixedly connected to the outer side of the positioning shell. A double-acting screw is fixedly connected to the inner side of the synchronous pulley. The outer side of the double-acting screw is rotatably connected to the inner side of the bearing seat. Two angle iron frames are fixedly connected to the outer side of the fixing frame. Bolts are inserted into the inner side of the angle iron frames. Nuts are threadedly connected to the outer side of the bolts. A sliding rod is fixedly connected to one end of the bolt. A sliding frame is slidably connected to the outer side of the sliding rod. A wiring roller is rotatably connected to one side of the sliding frame. The inner side of the sliding frame is threadedly connected to the outer side of the double-acting screw. A detection and protection mechanism is provided at the bottom of the outer shell.

[0007] By adopting the above technical solution: using synchronous pulley two to drive the bidirectional lead screw, the bidirectional lead screw can reciprocate the sliding frame and the wiring roller, so that the wiring roller can guide the winding and unwinding of the steel wire cable, and avoid the steel wire cable from getting tangled together during the winding process.

[0008] As a further description of the above technical solution: the detection and protection mechanism includes a steel wire cable, one end of which is fixedly connected to the outside of the cable tray, and a lifting ring is fixedly connected to one end of the steel wire cable. A probe cage is fixedly connected to the bottom of the lifting ring, and multiple openings are provided on the outside of the probe cage.

[0009] By adopting the above technical solution, the water quality detection sensor is protected by a probe cage, allowing water to enter the interior of the probe cage through the opening, reducing the impact of external water flow on the water quality detection sensor and improving the detection accuracy of the water quality detection sensor.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a lifting guide mechanism, compared with the existing technology, the sliding frame is driven by a two-way screw rod to perform two-way threaded transmission, so that the sliding frame can drive the wiring roller to reciprocate and guide the steel wire cable, so that the steel wire cable is evenly arranged during winding and unwinding, reducing friction, squeezing or knotting between cables, thereby reducing the risk of surface wear and internal wire breakage.

[0012] 2. By setting up a detection protection mechanism, compared with the existing technology, the probe cage is used to protect the water quality detection sensor, and multiple openings are used to separate water and larger impurities, which can reduce the impact of water flow on the water quality sensor, and at the same time avoid collision with underwater floating objects, thus preventing the sensor from being damaged by external forces.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-8 The automatic lifting device for the water quality monitoring sensor shown includes a housing 1, a bracket 2 fixedly connected to the inside of the housing 1, a fixed frame 3 fixedly connected to one side of the bracket 2, a limit frame 4 fixedly connected to the top of the fixed frame 3, a servo motor 5 fixedly connected to the top of the fixed frame 3, and a lifting guide mechanism provided on the outside of the fixed frame 3. The lifting guide mechanism includes a cable collection drum 6, one side of the cable collection drum 6 fixedly connected to the output end of the servo motor 5, one side of the cable collection drum 6 rotatably connected to the inside of the limit frame 4, a first synchronous pulley 7 fixedly connected to one side of the cable collection drum 6, a synchronous belt 8 drivenly connected to the outside of the first synchronous pulley 7, a second synchronous pulley 9 rotatably connected to the inside of the synchronous belt 8, a positioning shell 10 fixedly connected to the bottom of the fixed frame 3, two bearing seats 22 fixedly connected to the outside of the positioning shell 10, a double-acting screw 11 fixedly connected to the inside of the second synchronous pulley 9, and the outside of the double-acting screw 11 rotatably connected to the inside of the bearing seat 22. Two angle iron frames 14 are fixedly connected to the side. Bolts 15 are inserted into the inner side of the angle iron frames 14. Nuts 16 are threadedly connected to the outer side of the bolts 15. A sliding rod 17 is fixedly connected to one end of the bolts 15. A sliding frame 12 is slidably connected to the outer side of the sliding rod 17. A wiring roller 13 is rotatably connected to one side of the sliding frame 12. The inner side of the sliding frame 12 is threadedly connected to the outer side of the bidirectional lead screw 11. A detection and protection mechanism is set at the bottom of the outer casing 1. The servo motor 5 drives the cable drum 6 to transmit the synchronous pulley 7. The synchronous pulley 7 transmits the synchronous belt 8 and the synchronous pulley 9. The synchronous pulley 9 transmits the bidirectional lead screw 11. The bidirectional lead screw 11 transmits the sliding frame 12 and the wiring roller 13. The wiring roller 13 can guide the winding and unwinding of the steel wire cable 18, so that the steel wire cable 18 can remain neat when winding and unwinding inside the cable drum 6 and avoids them from intertwining.

[0024] Reference Figure 1 and Figure 2 As shown, the detection protection mechanism includes a steel wire cable 18. One end of the steel wire cable 18 is fixedly connected to the outside of the cable tray 6. A lifting ring 19 is fixedly connected to one end of the steel wire cable 18. A probe cage 20 is fixedly connected to the bottom of the lifting ring 19. Multiple openings 21 are provided on the outside of the probe cage 20. The probe cage 20 is used to protect the water quality detection sensor, and the multiple openings 21 are used to reduce the impact of water flow on the water quality detection sensor.

[0025] The working principle of this utility model is as follows: When testing water quality, the probe cage 20 is first opened, and the water quality monitoring sensor is placed inside the probe cage 20. Then, the servo motor 5 drives the cable drum 6 to transmit power, allowing the cable drum 6 to transmit and unwind the steel wire cable 18. The steel wire cable 18 moves into the water through the bottom lifting ring 19 and the probe cage 20. At the same time, the cable drum 6 transmits power to the first synchronous pulley 7, which in turn drives the second synchronous pulley 9 through the synchronous belt 8. Then, the second synchronous pulley 9 drives the bidirectional lead screw 11 to transmit power inside the positioning shell 10 and the two bearing seats 22. Under the transmission of the steel wire cable 18 by the cable drum 6, the steel wire cable 18 will reciprocate on the outside of the cable drum 6. At the same time, the bidirectional lead screw 11 drives the sliding frame 12 for threaded transmission, and the sliding frame 12 moves under the guidance of the sliding rod 17. The sliding frame 12 is driven to one side of the double-ended lead screw 11 via a threaded transmission. Under the continuous rotation of the double-ended lead screw 11, the sliding frame 12 is guided by the other thread of the double-ended lead screw 11, causing the sliding frame 12 to reciprocate on the outside of the double-ended lead screw 11. During the lifting and lowering of the steel wire cable 18, the wiring roller 13 on one side of the sliding frame 12 guides the outside of the steel wire cable 18, allowing the steel wire cable 18 to be lifted and lowered smoothly. At the same time, the wiring roller 13 guides the steel wire cable 18, ensuring that the steel wire cable 18 remains wound flat when wound inside the cable drum 6. Afterwards, the probe cage 20 is placed in the water through the bottom, and water enters the interior of the probe cage 20 through multiple openings 21 on the outside of the probe cage 20, allowing the water quality monitoring sensor inside the probe cage 20 to detect the water quality.
