Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and more specifically, to an adaptive water flow regulating device for water conservancy and hydropower engineering. Background Art

[0002] Aqueducts are one of the most important means of transporting (draining) man-made and natural water sources in human history. Together with the sedimentation-filtration-disinfection process, they form the most basic drinking water treatment system known to modern people. They are also widely used in agricultural irrigation and many other areas of life.

[0003] The document with prior art publication number CN215888123U provides a water diversion structure for water conservancy and hydropower projects. By setting a filter plate, impurities in the canal can be filtered, and the collected frame and driving assembly can be used to collect the filtered impurities and lift them upward to a place away from the water surface, so as to facilitate the cleaning of the impurities. Secondly, the device slides a limiting flow plate on the side wall on the other side of the filter, and is equipped with an adjustment mechanism, so that the flow rate of the water in the canal can be adjusted, thereby improving the practicability of the device.

[0004] Although the prior art solutions mentioned above can achieve the relevant beneficial effects through the prior art structures, the above water diversion structures cannot adaptively adjust the water flow according to the water level upstream or downstream. In view of this, we propose an adaptive water flow regulating device for water conservancy and hydropower engineering. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The purpose of this application is to provide an adaptive water flow regulating device for water conservancy and hydropower projects, which solves the technical problem in the prior art that the water flow cannot be adaptively adjusted according to the upstream or downstream water level, improves the flexibility of water diversion and water level regulation, and achieves the technical effect of adaptive water level regulation.

[0007] 2. Technical solution

[0008] The embodiment of the present application provides an adaptive water flow regulating device for water conservancy and hydropower engineering, including a water channel and a controller, a support frame is fixedly installed on the water channel, and a winch is fixedly installed on the support frame;

[0009] The water channel is slidably connected with a gate plate, which is used to control the discharge volume;

[0010] The steel cable of the hoist is fixedly connected to the gate plate;

[0011] A plurality of water level monitors are fixedly installed on the water channel to monitor the water level;

[0012] A plurality of water diversion holes are provided downstream of the water channel, and control valves are installed in the water diversion holes, and the control valves are used to control the opening of the corresponding water diversion holes;

[0013] The winch, monitor and control valve are all connected to the controller for communication.

[0014] By adopting the above technical solution, when the water diversion hole needs to divert water, the corresponding control valve opens and sends an opening signal to the controller. The controller controls the hoist to open according to the received control valve opening signal and the number of control valves opened. The hoist drives the gate plate to move upward, thereby discharging the water stored upstream of the gate plate to the downstream.

[0015] The height of the gate plate rises is related to the number of water diversion holes opened. The more water diversion holes are opened and the different water level thresholds corresponding to the number of opened water diversion holes, the greater the gate plate rises, thereby ensuring sufficient water supply;

[0016] During the rising process of the gate, the water level monitor monitors the water level downstream of the gate in real time. When the downstream water level reaches the corresponding water level threshold range, the water level monitor sends a signal to the controller. The controller controls the winch to stop working and the gate to stop rising and falling, thereby realizing the regulation of water flow.

[0017] As an optional solution of the technical solution of the present application document, at least one water level monitor is distributed on the upstream side and the downstream side of the gate.

[0018] By adopting the above technical solution, at least one water level monitor is distributed on the upstream and downstream sides of the gate, which respectively monitors the water levels upstream and downstream of the gate in real time, thereby regulating the stability of the water levels upstream and downstream.

[0019] As an optional solution to the technical solution of the present application document, a drainage hole is opened on the gate plate, guide frames are fixedly installed on both sides of the drainage hole, a telescopic cylinder is fixedly installed on the gate plate, the telescopic cylinder is communicatively connected with the controller, a baffle is fixedly installed on the output shaft of the telescopic cylinder, and the baffle is plugged into the guide frame for blocking the drainage hole.

[0020] By adopting the above technical scheme, during the water diversion process, when the water level monitor detects that the water level is continuously lower than the preset water level, after the gate plate is adjusted, the opening amount of the water diversion hole is increased in the subsequent water diversion work, thereby causing the water level to drop. After the controller receives the opening signal of the control valve, the controller controls the output shaft of the telescopic cylinder to drive the baffle to rise, thereby realizing the opening of the drain hole and increasing the drainage volume, thereby realizing a rapid increase in the drainage volume, effectively solving the problem of difficulty in adjusting the drainage through the gate plate, and improving the water diversion efficiency. When the downstream water level changes, the water level can be adaptively adjusted through real-time monitoring of the water level monitor and the linkage of the telescopic cylinder and the baffle.

[0021] As an optional solution of the technical solution of the present application document, a buckle groove is provided on the baffle plate, and the buckle groove is provided on the upstream side of the baffle plate.

[0022] By adopting the above technical solution and setting the buckle groove, the cross-sectional area of ​​the baffle gradually increases from top to bottom. When the baffle is in the state of blocking the drain hole, the buckle groove is subjected to the water pressure to keep the baffle stable.

[0023] As an optional solution of the technical solution of the present application document, a filter plate is fixedly installed on the water inlet side of the drain hole of the gate plate.

[0024] By adopting the above technical solution and setting the filter plate, it is possible to effectively reduce the flow of floating objects from the drainage hole into the downstream area during the drainage process, thereby filtering the floating objects.

[0025] During use, when the water diversion hole needs to divert water, the corresponding control valve opens and sends an opening signal to the controller. The controller controls the opening of the winch according to the received control valve opening signal and the number of control valves opened. The winch drives the gate plate to move up, thereby discharging the stored water upstream of the gate plate to the downstream; during the rising process of the gate plate, the water level monitor monitors the downstream water level of the gate plate in real time. When the downstream water level reaches the corresponding water level threshold range, the water level monitor sends a signal to the controller, and the controller controls the winch to stop working and the gate plate stops rising and falling; when the water level monitor detects that the water level is continuously lower than the preset water level, the water level monitor transmits the water level signal to the controller, and the controller controls the output shaft of the telescopic cylinder to drive the baffle to rise, so that the drain hole is opened and the drainage volume is increased, thereby realizing a rapid increase in drainage volume. The water level is adaptively adjusted through real-time monitoring of the water level monitor and coordinated with the linkage of the telescopic cylinder and the baffle.

[0028] 1. In this application, when the water diversion hole needs to divert water, the corresponding control valve opens and sends an opening signal to the controller. The controller controls the hoist to open according to the received control valve opening signal and the number of control valves opened. The hoist drives the gate plate to move up, thereby discharging the water stored upstream of the gate plate to the downstream;

[0029] During the rising process of the gate, the water level monitor monitors the water level downstream of the gate in real time.

[0038] The present application is further described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figures 1 to 5The present embodiment discloses an adaptive water flow regulating device for water conservancy and hydropower engineering, comprising a water channel 1 and a controller, a support frame 2 is fixedly mounted on the water channel 1, a winch 3 is fixedly mounted on the support frame 2, guide grooves 4 that are interconnected are provided on the water channel 1 and the support frame 2, a gate plate 5 is slidably connected in the guide groove 4, the gate plate 5 is used to control the discharge volume, a steel cable of the winch 3 is fixedly connected to the gate plate 5, a plurality of water level monitors 6 are fixedly mounted on the water channel 1 for monitoring the water level, at least one water level monitor 6 is distributed on the upstream and downstream sides of the gate plate 5, and the water levels upstream and downstream of the gate plate 5 are respectively monitored in real time, a plurality of water diversion holes 7 are provided downstream of the water channel 1, a control valve is installed in the water diversion hole 7, and the control valve is used to control the opening of the corresponding water diversion hole 7, so as to realize the external diversion of the water inside the water channel 1, and the winch 3, the monitor 6 and the control valve are all communicatively connected to the controller.

[0040] When the water diversion hole 7 needs to divert water, the corresponding control valve opens and sends an opening signal to the controller. The controller controls the opening of the winch 3 according to the received control valve opening signal and the number of opened control valves. The winch 3 drives the gate plate 5 to move upward, thereby discharging the stored water upstream of the gate plate 5 to the downstream.

[0041] It should be noted that the rising height of the gate plate 5 is related to the number of open water diversion holes 7. The more open water diversion holes 7 are and the different water level thresholds corresponding to the number of open water diversion holes 7, the greater the rising height of the gate plate 5 is, thereby ensuring sufficient water supply.

[0042] During the rising process of the gate plate 5, the water level monitor 6 monitors the downstream water level of the gate plate 5 in real time. When the downstream water level reaches the corresponding water level threshold range, the water level monitor 6 sends a signal to the controller, and the controller controls the winch 3 to stop working and the gate plate 5 to stop rising and falling, thereby realizing the regulation of the water flow.

A telescopic cylinder 10 is fixedly installed on the gate plate 5, and a baffle 11 is fixedly installed on the output shaft of the telescopic cylinder 10. The baffle 11 is plugged into the guide frames 9 to block the drain hole 8.

[0044] During the water diversion process, when the water level monitor 6 detects that the water level is continuously lower than the preset water level, after the gate plate 5 is adjusted, the opening amount of the water diversion hole 7 is increased in the subsequent water diversion work, thereby causing the water level to drop.

When the downstream water level changes, the water level is adaptively adjusted through real-time monitoring of the water level monitor 6 and the linkage of the telescopic cylinder 10 and the baffle 11.

[0045] A buckle groove 12 is provided on the baffle 11, and the buckle groove 12 is provided on the upstream side of the baffle 11. The arrangement of the buckle groove 12 gradually increases the cross-sectional area of ​​the baffle 11 from top to bottom. When the baffle 11 is in the state of blocking the drain hole 8, the buckle groove 12 is subjected to the action of water pressure to keep the baffle 11 stable.

[0046] A filter plate 13 is fixedly installed on the water inlet side of the drain hole 8 of the gate plate 5, which can effectively reduce the flow of floating objects from the drain hole 8 into the downstream area during the drainage process, thereby filtering the floating objects.

[0047] The water level monitor 6 on the upstream side monitors the water level upstream. When the water level upstream increases rapidly, the gate 5 can be opened to adjust the water level upstream to be stable.

[0048] When an adaptive water flow regulating device for water conservancy and hydropower engineering disclosed in an embodiment of the present application is used, when the water diversion hole 7 needs to divert water, the corresponding control valve is opened and sends an opening signal to the controller. The controller controls the hoist 3 to open according to the received control valve opening signal and the number of control valves opened, and the hoist 3 drives the gate plate 5 to move upward, thereby discharging the stored water upstream of the gate plate 5 to the downstream; during the rising process of the gate plate 5, the water level monitor 6 monitors the downstream water level of the gate plate 5 in real time. When the downstream water level reaches the corresponding water level threshold range, the water level monitor 6 sends a signal to the controller, and the controller controls the hoist 3 to stop working and the gate plate 5 to stop lifting; when the water level monitor 6 detects that the water level is continuously lower than the preset water level, the water level monitor 6 transmits the water level signal to the controller, and the controller controls the output shaft of the telescopic cylinder 10 to drive the baffle 11 to rise, so that the drain hole 8 is opened, and the drainage volume is increased, thereby realizing a rapid increase in drainage volume, and the water level is adaptively adjusted through real-time monitoring of the water level monitor 6 and the linkage of the telescopic cylinder 10 and the baffle 11.
