Description

Technical Field

[0001] This utility model relates to the field of sediment monitoring technology, and in particular to an inlet sediment monitoring sensor installation assembly. Background Technology

[0002] In the field of water conservancy engineering, water diversion tunnels are key facilities for water resource allocation and hydropower generation. The sediment content at their inlets directly affects the operational safety and efficiency of subsequent water conservancy equipment. Excessive sediment can cause problems such as unit wear and pipe blockage. Therefore, it is necessary to monitor the sediment content at the inlet in real time and accurately.

[0003] Currently, the industry generally uses sediment sensors as the core monitoring equipment for sediment content at water inlets, and the sensors need to be installed directly at the inlet of the water diversion tunnel to obtain monitoring data that most closely reflects the actual working conditions. However, the water flow at the inlet of the water diversion tunnel is rapid and the sediment concentration is high. During the operation of the sensor, its sensing surface is easily adhered to and deposited by suspended sediment.

[0004] In existing technologies, the installation structure of sediment sensors can only achieve the functions of fixing and positioning the sensor, lacking a specific design for sediment removal. Adhered sediment can obstruct the sensor's sensing area, leading to distorted monitoring signals, a significant decrease in data accuracy, and in severe cases, sensor malfunction and shutdown. Furthermore, manual cleaning requires downtime, which not only affects the normal operation of water conservancy projects but also increases maintenance costs and operational risks.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] This utility model provides an inlet sediment monitoring sensor installation assembly with a simple structure that can be adapted to install different models of sediment sensors. It can also automatically clean the measuring end of the sediment sensor without manual cleaning, effectively solving the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An inlet sediment monitoring sensor mounting assembly includes a sediment monitoring sensor, which comprises a sensor body and a mounting ring fixed to the surface of the sensor body; it also includes: The inner wall of the ring extends inward to form a support portion for supporting the mounting ring, and the measuring end of the sensor body protrudes from the bottom of the ring. The bracket has one end connected to the ring and the other end connected to the wall at the inlet of the water diversion tunnel; The lifting frame can slide along the axis of the ring. The lifting frame is rotatably mounted with a rotating shaft. One end of the swing arm is fixed to the rotating shaft, and the other end of the swing arm is provided with a nozzle facing the measuring end of the sensor body. It also includes a drive mechanism for rotating the swing arm.

[0008] Furthermore, the drive mechanism includes a connecting rod fixed to one end of the swing arm, and the connecting rod has a strip-shaped hole; The drive mechanism also includes a power mechanism fixed on the lifting frame, and the output end of the power mechanism is fixed with a push shaft passing through the strip hole.

[0009] Furthermore, the pitch angle of the nozzle is adjustable and mounted on the other end of the swing arm.

[0010] Furthermore, both ends of the nozzle are fixed with optical shafts that pass through the other end of the swing arm. One optical shaft is fixed with a plug, and the other optical shaft is threaded with a nut.

[0011] Furthermore, a hose is connected to the water inlet of the nozzle, and the hose is fixed to the swing arm by a clamp. The hose between the nozzle and the clamp closest to it is in a loose state.

[0012] Furthermore, the circular threaded connection has at least three bolts, one end of which abuts against the mounting ring.

[0013] Furthermore, the lifting frame has at least three bolts 2 connected by threads, with one end of each bolt 2 abutting against a ring.

[0014] Furthermore, a reinforcing rod is fixed between the connecting rod and the swing arm.

[0015] The technical solution of this utility model can achieve the following technical effects: When cleaning is required, a cleaning command can be triggered by timed control or abnormal feedback of mud and sand sensor data: the drive mechanism starts to rotate the swing arm around the axis of rotation to the position where the measuring end is facing; then the nozzle opens and sprays a cleaning medium such as high-pressure water jet onto the measuring end of the sensor body to quickly erode the attached mud and sand; after the cleaning operation is completed, the drive mechanism reverses and drives the swing arm and nozzle to rotate back to the initial parking position, and the sensor returns to normal monitoring state. The whole process does not require manual intervention and can realize automated cyclic cleaning. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] This application provides an inlet sediment monitoring sensor mounting assembly, including a sediment monitoring sensor. The sediment monitoring sensor includes a sensor body 1 and a mounting ring 2 fixed to the surface of the sensor body 1. More specifically, the sensor body 1 is an ultrasonic sensor, with its measuring end located at the bottom of the sensor body 1. It also includes: Reference Figure 1 and Figure 3 The inner wall of the ring 3 extends inward to form a support part 4 for supporting the mounting ring 2, and the measuring end of the sensor body 1 protrudes from the bottom end of the ring 3. The bracket is connected at one end to the ring 3 and at the other end to the wall at the inlet of the water diversion tunnel. More specifically, the bracket can be telescopic or fixed in length and is fixed to the wall at the inlet of the water diversion tunnel by expansion bolts. The lifting frame 5 can slide along the axis of the ring 3. More specifically, tracks 7 are evenly distributed on the outer wall of the ring 3, and the lifting frame 5 is slidably connected to the tracks 7. The lifting frame 5 is rotatably mounted with a rotating shaft 6. More specifically, the rotating shaft 6 is rotatably mounted on the lifting frame 5 through a bearing seat, and the rotating shaft 6 is horizontally set. One end of the swing arm 8 is fixed to the rotating shaft 6, and the other end of the swing arm 8 is provided with a nozzle 9 facing the measuring end of the sensor body 1. The swing arm 8 and the nozzle 9 can rotate around the axis of the rotating shaft 6. Since the heights of different sensor bodies 1 are different, the length of the swing arm 8 is fixed. In order to adapt to the different heights of the sensor bodies 1, the lifting frame 5 is set to be able to slide along the axis of the ring 3. It also includes a drive mechanism 10 for driving the swing arm 8 to rotate. When cleaning is required, the drive mechanism 10 is operated to rotate the swing arm 8 and the nozzle 9 around the axis of the rotating shaft 6 to the state shown in the figure. The nozzle 9 is turned on to clean the measuring end. After cleaning is completed, the drive mechanism 10 is operated to rotate the swing arm 8 and the nozzle 9 around the axis of the rotating shaft 6 to the parking position to prevent the nozzle 9 and the swing arm 8 from affecting the normal operation of the measuring end. The specific operation process of this device is as follows: First, adjust the relative position of the lifting frame 5 and the ring 3 according to the height of the sensor body 1 so that the nozzle 9 can face the measuring end. After the components are installed, the swing arm 8 and the nozzle 9 are in a parking position away from the measuring end of the sensor body 1 under the action of the drive mechanism 10. The sensor is not blocked and can normally collect the sediment content data at the inlet of the water diversion tunnel. When cleaning is required, a cleaning command can be triggered by timed control or abnormal feedback from the sediment sensor data: the drive mechanism 10 starts to rotate the swing arm 8 around the axis of the rotating shaft 6 to the position where the measuring end is facing the target; then the nozzle 9 opens and sprays a cleaning medium, such as high-pressure water, onto the measuring end of the sensor body 1 to quickly erode the attached sediment; after the cleaning operation is completed, the drive mechanism 10 reverses and drives the swing arm 8 and the nozzle 9 to rotate back to the initial parking position, and the sensor returns to normal monitoring status. The whole process does not require manual intervention and can realize automated cyclic cleaning.

[0021] As a preferred embodiment of the above, refer to Figure 2 The drive mechanism 10 includes a connecting rod 101 fixed to one end of the swing arm 8, and the connecting rod 101 has a strip hole 102. The drive mechanism 10 also includes a power mechanism 103 fixed on the lifting frame 5. The output end of the power mechanism 103 is fixed with a push shaft 104 passing through the strip hole 102. When in a clean state, there is an angle between the movement trajectory of the strip hole 102 and the push shaft 104. In the above embodiments, the power mechanism 103 adopts a waterproof electric telescopic rod or similar structure, such as... Figure 2As shown, the rotating shaft 6 is located at the connection between the connecting rod 101 and the swing arm 8, and the connecting rod 101 and the swing arm 8 have a certain angle. The operation of the drive mechanism 10 is as follows: When the cleaning command is triggered, the power mechanism 103 starts and extends outward. The push shaft 104 at its output end slides along the strip hole 102 on the connecting rod 101. Since the connecting rod 101 and the swing arm 8 have an angle and the two are connected by a rotating shaft 6, the linear thrust of the push shaft 104 is converted into the rotational force of the connecting rod 101 around the rotating shaft 6, which drives the swing arm 8 and the nozzle 9 to rotate synchronously to the cleaning position directly opposite the sensor measuring end.

[0022] As a preferred embodiment of the above, the pitch angle of the nozzle 9 is adjustable and mounted on the other end of the swing arm 8; In the above embodiment, the pitch angle of the nozzle 9 is adjustable, which allows the nozzle 9 to be aligned with the sensing area of ​​the sensor measuring end, avoiding cleaning dead corners and improving the mud and sand flushing effect.

[0023] As a preferred embodiment of the above, refer to Figure 4 Both ends of the nozzle 9 are fixed with optical shafts 11 that pass through the other end of the swing arm 8. One optical shaft 11 is fixed with a plug, and the other optical shaft 11 is threaded with a nut 12. In the above embodiment, the nozzle 9 is assembled with the swing arm 8 via optical shafts 11 at both ends. One end is limited by a plug, and the other end is locked by a nut 12. Loosening the nut 12 allows for flexible adjustment of the pitch angle of the nozzle 9, while tightening it securely locks the required angle. This design has the advantages of simple structure and convenient operation.

[0024] As a preferred embodiment of the above, refer to Figure 2 The nozzle 9 has a hose 13 connected to its water inlet end. The hose 13 is fixed to the swing arm 8 by a clamp. The hose 13 between the nozzle 9 and the clamp closest to it is in a relaxed state. In the above embodiment, the hose 13 connected to the water inlet of the nozzle 9 is fixed to the swing arm 8 by a clamp, and the hose 13 between the nozzle 9 and the adjacent clamp is in a relaxed state, which can meet the action requirements of the nozzle 9 to adjust the pitch angle. The clamp can also straighten the direction of the hose 13 to prevent the hose 13 from getting tangled or colliding with the sensor or swing arm 8 under the impact of water flow, thus extending its service life.

[0025] As a preferred embodiment of the above, refer to Figure 1 and Figure 3 The ring 3 is threaded with at least three bolts 14, one end of which abuts against the mounting ring 2; In the above embodiment, bolt 14 is selected so that its end does not protrude from the inner wall of the ring 3, and then the sediment sensor is placed. When installing the sediment sensor, the mounting ring 2 is placed on the bearing part 4, and then the bolt 14 is rotated to fix the sediment sensor to prevent the sediment sensor from changing position during monitoring.

[0026] As a preferred embodiment of the above, refer to Figure 1 and Figure 3 The lifting frame 5 has at least three bolts 215 connected by threads, and one end of bolt 215 abuts against the ring 3; In the above embodiment, the position of the lifting frame 5 is adjusted by loosening bolt 15, and after adjustment, the position of the lifting frame 5 is fixed by tightening bolt 15. As a preferred embodiment of the above, refer to Figure 2 A reinforcing rod 105 is fixed between the connecting rod 101 and the swing arm 8; In the above embodiment, the reinforcing rod 105, the connecting rod 101 and the swing arm 8 form a triangular structure to prevent the connecting rod 101 and the swing arm 8 from breaking.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
