They are unable to accurately adjust the flow and water level of river channels according to actual needs, and cannot meet the diverse control requirements in complex water conservancy environments. Secondly, their automation level is low, with a large proportion of manual operation, making it impossible to respond and adjust quickly in real time according to changes in water flow, resulting in low control efficiency.

Detailed Implementation

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] This utility model provides an intelligent water flow control device for water conservancy facilities. Please refer to [reference needed]. Figures 1-6 As shown, the structure includes a water dike 1, with a fixed plate 5 fixedly connected to the inner wall of the water dike 1. A main gate assembly 4 is fixedly connected between two fixed plates 5. A control mechanism 6 is provided on the top of one of the fixed plates 5. A secondary gate 7 is provided inside the main gate assembly 4. A mounting frame 3 is fixedly connected to the top of the water dike 1. A drive mechanism is provided on the top of the mounting frame 3. The secondary gate 7 moves up and down by being driven by the drive mechanism. A water level monitoring mechanism 2 is provided on the inner side of the water dike 1. A controller 12 is provided on one side of the mounting frame 3.

[0024] The main gate assembly 4 includes a main gate body 41 fixedly connected between two fixed plates 5. A number of equally spaced guide grooves 42 are provided on one side of the main gate body 41. A slot 43 adapted to the auxiliary gate 7 is provided on the top of the main gate body 41. Sliding grooves 44 are provided on both sides of the slot 43. Sliding blocks 13 that are slidably connected to the sliding grooves 44 are fixedly connected to the bottom of both sides of the auxiliary gate 7.

[0025] In this embodiment, the water level monitoring mechanism 2 can monitor water level changes in real time and transmit the collected water level data to the controller 12 via a dedicated line in the form of electrical signals. The controller 12 is a PLC controller, which compares and analyzes the data with preset water level thresholds and control strategies. For example, when the upstream infrared sensor 25 detects that the water level has reached the warning value and continues to rise, the control system determines, based on the flood control strategy, that the discharge volume needs to be increased. If the downstream water level is too low, in order to ensure ecological water use, it determines that the water flow rate needs to be increased. Subsequently, the control system generates corresponding control commands based on the analysis results and sends them to the drive system. After receiving the commands from the controller 12, the drive system starts working, thereby adjusting the main gate. The opening and closing degree of the main gate body 41 and the opening or closing degree of the auxiliary gate 7 can be adjusted through the coordinated work of the main gate body 41 and the auxiliary gate 7 to realize a variety of water flow control modes. According to different river water flow needs, the flow rate and water level can be precisely adjusted. The communication module equipped with the controller 12 is connected to the remote monitoring center through a wireless network. At the remote monitoring center, the staff can view the operating status of each part of the device in real time, water level monitoring data, drive system operating parameters, etc. If the actual operation is found to be inconsistent with the expectations, or if the control strategy needs to be adjusted, the staff can send instructions to the control system through the remote monitoring center to realize remote control of the device and parameter adjustment, ensuring that the river water flow is always in a reasonable control state.

[0026] Furthermore, the water level monitoring mechanism 2 includes a limiting cylinder 21 fixedly connected to the inner side of the dike 1. The inner walls on both sides of the limiting cylinder 21 are provided with sliding grooves 22. A float 24 is slidably connected inside the limiting cylinder 21. A slider 23 that is slidably connected to the sliding groove 22 is fixedly connected to both sides of the float 24. The water level monitoring mechanism 2 also includes an infrared sensor 25 fixedly connected to the dike 1.

[0027] In use, the infrared sensor 25 is model TSSP93038DF1 PZA. The water level monitoring mechanism 2 is located on the water-facing side of the gate that is in contact with the river. The bottom of the water level monitoring mechanism 2 is inserted into the riverbed, and the top is close to the bank. The inner walls of both sides of the limiting cylinder 21 are provided with sliding grooves 22 that communicate with the river. The sliding grooves 22 are cubic and are sized so that they cannot fall out of the limiting cylinder 21. The slider 23 moves up and down along the sliding grooves 22, so that the float 24 can move up and down stably. The infrared sensor 25 is connected to the riverbank directly above the float 24 to detect the distance between the float 24 and the riverbank. In order to make the detection more accurate, a sensing plate is provided on the side of the float 24 facing the infrared sensor 25, so that the water level changes can be monitored in real time.

[0028] Furthermore, the control mechanism 6 includes a first motor 61 fixedly installed on the top of the fixed plate 5. The output end of the first motor 61 is fixedly connected to a rotating rod 62. The rotating rod 62 is located inside the fixed plate 5 and is fixedly sleeved with several equidistantly distributed worm gears 63. A worm wheel 64 is meshed on one side of the worm gear 63. A rotating shaft 65 is fixedly connected to one end of the worm wheel 64. A guide plate 66 is rotatably connected to one end of the rotating shaft 65.

[0029] In use, by controlling the start of the first motor 61, the first motor 61 drives the rotating rod 62 to rotate, the rotating rod 62 drives the worm gear 63 to rotate, and the meshing of the worm gear 63 and the worm wheel 64 drives the rotating shaft 65 to rotate, thereby driving the guide plate 66 to rotate. This allows for flexible adjustment of the angle of the guide plate 66 according to actual needs, thus facilitating the control of the water flow rate.

[0030] Furthermore, the drive mechanism includes a second motor 8 fixedly mounted on the top of the mounting bracket 3. The output shaft of the second motor 8 is fixedly connected to a drive gear 9. The drive gear 9 meshes with the driven gear 10. The driven gear 10 meshes with one side of the drive gear 9. A threaded rod 11 is threadedly connected to the middle of the driven gear 10. The threaded rod 11 passes through the mounting bracket 3 and extends to the bottom end, which is fixedly connected to the top of the auxiliary gate 7. A limit block is fixedly sleeved on the top of the driven gear 10.

[0031] In operation, the second motor 8 is started by controlling the second motor to drive the drive gear 9 to rotate. The meshing of the drive gear 9 and the driven gear 10 causes the threaded rod 11 to move up and down, thereby driving the auxiliary gate 7 to move up and down along the slot 43. This allows for flexible adjustment of the opening or closing degree of the auxiliary gate 7, thus enabling multiple water flow control modes and precise adjustment of flow rate and water level according to different river flow requirements.

[0032] The working principle of this utility model is as follows: During use, the water level monitoring mechanism 2 can monitor water level changes in real time and transmit the collected water level data to the controller 12 via a dedicated line in the form of electrical signals. The controller then starts the first motor 61, which drives the rotating rod 62 to rotate. The rotating rod 62 drives the worm gear 63 to rotate, and the meshing of the worm gear 63 and worm wheel 64 drives the rotating shaft 65 to rotate, thereby driving the guide plate 66 to rotate. This allows for flexible adjustment of the angle of the guide plate 66 according to actual needs. Simultaneously, the controller starts the second motor 8, which drives the main... The rotation of the driving gear 9 causes the meshing of the driving gear 9 and the driven gear 10 to move the threaded rod 11 up and down, thereby moving the auxiliary gate 7 up and down along the slot 43. This allows for flexible adjustment of the opening or closing degree of the auxiliary gate 7, enabling various water flow control modes. The flow rate and water level can be precisely adjusted according to different river flow requirements. For example, under normal water flow conditions, a smaller flow rate can be controlled by adjusting the height of the auxiliary gate 7. When a flood occurs and rapid flood discharge is required, the main gate body 41 and the auxiliary gate 7 can be opened simultaneously to increase the water flow and improve flood discharge efficiency.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
