Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for hydraulic engineering, and specifically relates to a diversion flow regulator for water conservancy projects. Background Technique
[0002] A water conservancy project is a general term for various engineering constructions built to control, utilize, and protect surface and underground water resources and the environment. In order to achieve flood discharge and irrigation, a rotatable regulating plate is usually installed at the connection between the main canal and the branch canal. By rotating the regulating plate, the flow-through area is changed to adjust the water flow into the branch canal. During the rotation of the regulating plate, it will be affected by the resistance from the water flow. If the water flow impact is too large during the flood season, it will interfere with the normal rotation of the regulating plate, thereby affecting the diversion flow regulation function of the overall ditch. Content of the Utility Model
[0003] The purpose of the utility model is to provide a diversion flow regulator for water conservancy projects. A movable baffle is installed on one side of the regulating plate. The baffle can move to block the diversion opening of the branch canal, reducing the impact of the water flow on the regulating plate and solving the problems in the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: A diversion flow regulator for a water conservancy project, including a main canal wall, a branch canal diversion opening is provided on the main canal wall, a partition frame is installed in the branch canal diversion opening, several openings are provided on the partition frame, and rotatable regulating plates are installed in each opening. The regulating plates can adjust the flow area of the openings and the water flow in the branch canal diversion opening. T-shaped grooves are provided on the inner sides of the main canal wall on the upper and lower sides of the branch canal diversion opening, and a movable baffle is installed on the T-shaped grooves. The baffle is provided with sliders that cooperate with the T-shaped grooves. A detachable locking pin is also installed between the baffle and the inner side of the main canal wall. The locking pin can fix the baffle on the main canal wall at one end away from the branch canal diversion opening. After removing the locking pin, the baffle can move along the T-shaped groove to block the branch canal diversion opening. The upper and lower ends of the regulating plates are both provided with rotating shafts. The rotating shafts at the lower ends of all the regulating plates are hinged and installed with a synchronous rotating plate. A worm gear is installed on the rotating shaft at the upper end of one of the regulating plates. A control box is installed on the main canal wall. A worm that cooperates with the worm gear is installed in the control box through a bearing. A handle is installed at one end of the worm that extends out of the control box. Rotating the handle can drive all the regulating plates to rotate synchronously in the branch canal diversion opening. A rubber plate is installed on the side of the baffle close to the branch canal diversion opening. A limiting plate is provided on the inner side of the main canal wall on one side of the branch canal diversion opening. When the rubber plate contacts the limiting plate, the baffle can block the branch canal diversion opening. On one side of each opening in the branch canal diversion opening, an anti-scouring iron block is fixedly provided. The anti-scouring iron block is located at one end away from the locking pin. The cross-section of the anti-scouring iron block is triangular, and the included angle between the oncoming flow surface of the anti-scouring iron block and the inner side surface of the main canal wall is an acute angle. A folding plate is provided on the side of the baffle away from the branch canal diversion opening. A vertically arranged hand push rod is installed on the upper side of the baffle. A locking sleeve is installed on the main canal wall. A locking pin is installed in the locking sleeve in a matching manner. A through hole that cooperates with the locking pin is provided in the folding plate. When the locking pin is located in the through holes on the locking sleeve and the folding plate, the baffle can be fixed on the main canal wall on one side of the branch canal diversion opening.
[0005] The positive effect of the utility model is as follows: For the diversion flow regulator for a water conservancy project described in the utility model, several rotatable regulating plates are installed in the branch canal diversion opening provided on the main canal wall. T-shaped grooves are provided on the upper and lower sides of the branch canal diversion opening, and a movable baffle is installed in the T-shaped grooves in a matching manner. When it is not necessary to rotate the regulating plates, or the interference of the water flow impact during the non-flood season on the rotation of the regulating plates is relatively small, the baffle can be fixed on the main canal wall on one side of the branch canal diversion opening through the locking pin, fully leaving the space of the branch canal diversion opening to allow the water flow to smoothly enter the branch canal. When the water flow impact interferes with the rotation of the regulating plates and it is necessary to rotate the regulating plates, after removing the locking pin, the baffle can move to block the branch canal diversion opening, minimizing the impact of the water flow on the regulating plates to the greatest extent, so as to facilitate the rotational adjustment of the regulating plates. After the adjustment is completed, the baffle can be moved back to its original position. The setting of the movable baffle can effectively reduce the impact of the water flow on the regulating plates, ensure the normal rotation of the regulating plates, and thus realize the diversion flow regulation function of the corresponding canals.

[0014] A flow regulator for diverting water flow in a water conservancy project according to the present utility model, as Figures 1 - 3 shown, includes a main canal wall 1. A branch canal diversion opening 2 is provided on the main canal wall 1. A partition frame 19 is installed in the branch canal diversion opening 2. A number of openings 20 are provided on the partition frame 19. A number of rotatable adjusting plates 3 are installed in each opening 20. The adjusting plates 3 can adjust the flow - through area of the openings 20 and the water flow in the branch canal diversion opening 2. Among them, the main canal wall 1 can be used as a part of the main canal to install the overall flow regulator. The outer side of the branch canal diversion opening 2 is used to connect the branch canal. By adjusting the rotation angle of the adjusting plates 3, the opening area of the branch canal diversion opening 2 can be adjusted, and thus the water flow into the branch canal can be adjusted.
[0015] On the inner side of the main canal wall 1 on the upper and lower sides of the branch canal diversion opening 2, a T - shaped groove 4 is provided. A movable baffle plate 5 is installed on the T - shaped groove 4. A sliding block 6 matching with the T - shaped groove 4 is provided on the baffle plate 5. The baffle plate 5 can move along the length direction of the T - shaped groove 4. A detachable locking pin 7 is also installed between the baffle plate 5 and the inner side of the main canal wall 1. The locking pin 7 can fix the baffle plate 5 on the main canal wall 1 at one end far from the branch canal diversion opening 2. After removing the locking pin 7, the baffle plate 5 can move along the T - shaped groove 4 to block the branch canal diversion opening 2.
[0016] After the rotation angle of the adjusting plate 3 is adjusted, in order not to affect the water flow from the main canal into the branch canal, the baffle 5 needs to be locked on the inner side of the main canal wall 1 on one side of the branch canal diversion opening 2 to prevent the baffle 5 from blocking the water flow into the branch canal. If it is necessary to adjust the water flow into the branch canal, when rotating the adjusting plate 3, in order to reduce the rotational interference of the water flow impact on the adjusting plate 3, the baffle 5 needs to be moved to the position of the branch canal diversion opening 2 to cut off a part of the water flow, thereby reducing the impact of the water flow on the adjusting plate 3 and facilitating the rotational adjustment of the adjusting plate 3.
[0017] The completion of the rotation action of the adjusting plate 3 can be achieved by installing a gear on the rotating shaft of the adjusting plate 3 and driving it by an electric push rod with a rack, or by installing a rotating motor on the rotating shaft of each adjusting plate 3. Since the installation environment of the overall device is poor, located outdoors and humid, the use of electrical components such as electric push rods or rotating motors will be restricted to a certain extent. In order to simplify the device for driving the rotation of the adjusting plate 3 and improve its durability for outdoor use, as Figure 4 shown, rotating shafts are provided at both the upper and lower ends of the adjusting plate 3. A synchronous rotating plate 8 is hinged to the rotating shafts at the lower ends of all the adjusting plates 3. A worm gear 9 is installed on the rotating shaft at the upper end of one of the adjusting plates 3. A control box 10 is installed on the main canal wall 1. A worm 11 that cooperates with the worm gear 9 is installed in the control box 10 through a bearing. A handle 12 is installed at one end of the worm 11 extending out of the control box 10. Rotating the handle 12 can drive all the adjusting plates 3 to rotate synchronously within the branch canal diversion opening 2.
[0018] In the above structure, the cooperating worm 11 and worm gear 9 can achieve a self-locking function. After the rotation angle of the adjusting plate 3 is adjusted, the impact of the water flow will not change the rotational position of the adjusting plate 3 itself. When it is necessary to adjust the opening and closing angle of the adjusting plate 3, it can be achieved by manually rotating the handle 12. The connection between the synchronous rotating plate 8 and the rotating shaft at the lower end of the adjusting plate 3 is similar to a parallelogram mechanism. As long as one of the adjusting plates 3 rotates, the rest of the adjusting plates 3 will rotate synchronously.
[0019] During the movement of the baffle 5, it will be impacted by the water flow, which plays an auxiliary thrust role in the movement and closing of the baffle 5. If the water flow impact during the flood season is too large, it will cause the baffle 5 to move quickly and have a hard collision, posing a high safety hazard to the operator and reducing the service life of the baffle 5. To solve the above problems, a rubber plate 13 is installed on the side of the baffle 5 close to the branch canal diversion opening 2, and a limiting plate 14 is provided on the inner side of the main canal wall 1 on one side of the branch canal diversion opening 2. When the rubber plate 13 contacts the limiting plate 14, the baffle 5 can block the branch canal diversion opening 2. At the same time, the setting of the rubber plate 13 can generate a buffer during the movement under the impact of the water flow, thereby effectively extending the service life of the baffle 5.
[0020] Furthermore, in order to conform to the direction of the water flow into the branch canal and reduce the impact damage of the water flow and sediment on the side of the branch canal diversion port 2, as Figure 5 shown, anti-scouring iron blocks 15 are fixedly arranged on one side of each hole 20 in the branch canal diversion port 2. The anti-scouring iron blocks 15 are located at the end far from the locking pin 7. The cross-section of the anti-scouring iron block 15 is triangular, and the included angle between the water-facing surface of the anti-scouring iron block 15 and the inner side surface of the main canal wall 1 is an acute angle.
[0021] Furthermore, in order to increase the auxiliary push of the water flow on the movement of the baffle 5, a folding plate 16 is arranged on the side of the baffle 5 away from the branch canal diversion port 2. A vertically arranged hand push rod 18 is installed on the upper side of the baffle 5, and an operator can hold the hand push rod 18 to pull the baffle 5 for movement adjustment.
[0022] When the baffle 5 is not required to block the branch canal diversion port 2, in order to lock the baffle 5 on the main canal wall 1, a locking sleeve 17 is installed on the main canal wall 1. A locking pin 7 is fitted in the locking sleeve 17. A through hole matching the locking pin 7 is formed in the folding plate 16. When the locking pin 7 is located in the through holes of the locking sleeve 17 and the folding plate 16, the baffle 5 can be fixed on the main canal wall 1 on one side of the branch canal diversion port 2. When it is necessary to move the baffle 5 to the branch canal diversion port 2 for blocking, only the locking pin 7 needs to be pulled out from the locking sleeve 17, as Figure 6 shown. Under the impact of the water flow, the baffle 5 can move in place along the T-shaped groove 4. Under the premise that the water flow impact force is not large during the above operation process, the staff can perform auxiliary pushing through the hand push rod 18.
[0023] The technical solution of the present utility model is not limited within the scope of the embodiments described in the present utility model. The technical content not elaborated in the present utility model is all well-known technologies.
