Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a river dam of a water conservancy project. Background Art

[0002] A water conservancy project dam is a building or facility, usually made of concrete, steel bars and other materials, used to intercept and control the flow of river water. The dam can adjust the water level as needed, control floods, direct the water flow in a specific direction, stabilize the river water level, etc. It is one of the important facilities commonly used in water conservancy projects. However, the existing water conservancy project dams still have the following problems in actual use:

[0003] Patent No. "CN202122515225.9" discloses a water conservancy project dam. When the device is in use, the user first puts the dam body into the river, and then installs two touch sensors at the water level that meets the conditions for opening the gate. The floating plate changes with the water level in the river. When the water level rises, the floating plate rises accordingly. When the floating plate touches the touch sensor, since the circuit of the touch sensor is connected to the warning light, the warning light will light up to remind the staff that the water level is too high to open the dam body. Then the staff starts the dual-axis motor, and the dual-axis motor drives the two gears to rotate. After the gears rotate, the rack moves upward, so that the dam body rises along the slide rail to complete the opening of the gate. During the use of the device, the staff is required to always observe the warning light to avoid disasters caused by untimely discovery when the water level rises, which makes the overall practicality of the device poor. In addition, the device filters impurities during use. When too many impurities accumulate, it will affect the water flow rate and reduce the efficiency of the device. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-7 As shown, a water conservancy project dam gate includes: a frame 1, a filter screen 2, a blocking mechanism 3, a water level monitoring mechanism 4 and a flow rate detection mechanism 5. The filter screen 2 is arranged on the side of the frame 1, and the blocking mechanism 3 is slidably connected to the inner side of the frame 1. The frame 1 is slidably connected to the water level monitoring mechanism 4, and the water level monitoring mechanism 4 is connected to the side of the flow rate detection mechanism 5. The flow rate detection mechanism 5 is arranged on the inner side of the filter screen 2. When the device is in use, the position of the water level monitoring mechanism 4 is first adjusted according to the water level height required to open the gate and release water. When the water level rises to the position of the water level monitoring mechanism 4, the blocking mechanism 3 is triggered to rise through the water level monitoring mechanism 4 to discharge the water. When the water level is lower than the position of the water level monitoring mechanism 4, the water level monitoring mechanism 4 drives the blocking mechanism 3 to descend for blocking. At the same time, the flow rate of water is monitored by the flow rate detection mechanism 5. When the flow rate slows down, the filter screen 2 is blocked by debris. At this time, the staff is reminded that the filter screen 2 needs to be cleaned to facilitate the continued operation of the device.

[0026] The blocking mechanism 3 includes a driving motor 31, a threaded rod 32 and a river gate plate 33. The driving motor 31 is arranged on the upper end of the frame 1. The output shaft of the driving motor 31 is connected to the threaded rod 32. The threaded rod 32 is rotatably connected to the inner side of the frame 1. The inner side of the frame 1 is slidably connected to the river gate plate 33. When the device is in use, the alarm switch 47 triggers the driving motor 31, and the threaded rod 32 is driven to rotate by the driving motor 31. During the rotation of the threaded rod 32, the river gate plate 33 is driven to slide and rise on the inner side of the frame 1.

[0027] The dam gate 33 is threadedly connected to the threaded rod 32, and waterproof plates 34 are symmetrically arranged on both sides of the dam gate 33. The side edges of the waterproof plates 34 are symmetrically threadedly connected with first positioning bolts 35. When the device is in use, during the long-term use of the device, in the dry season, the waterproof plate 34 can be directly removed by removing the first positioning bolts 35, so that the waterproof layer and other materials can be re-sprayed without dismantling the entire device, thereby improving the overall convenience of the device.

[0028] The water level monitoring mechanism 4 comprises a slide groove 41 , a slide plate 42 and a floating plate 43 . The slide groove 41 is symmetrically provided on the inner side of the frame 1 . The slide groove 41 is slidably connected to the slide plate 42 . The side of the slide plate 42 is connected to the floating plate 43 .

[0029] The slide groove 41 is slidably connected to a housing 44 , and the housing 44 is slidably connected to a slider 45 . Two spring columns 46 are symmetrically arranged inside the housing 44 , and an alarm switch 47 is arranged between the spring columns 46 .

[0030] A connecting block 48 is connected to the upper end of the shell 44, and a second positioning bolt 49 is threadedly connected to the connecting block 48. When the device is in use, the second positioning bolt 49 is rotated so that the second positioning bolt 49 is no longer in contact with the slide groove 41. At this time, the shell 44 can be slid, and the height of the shell 44 can be adjusted as needed to trigger the blocking mechanism 3. When the water level rises, the float 43 rises due to buoyancy, and at the same time drives the slide plate 42 to slide inside the slide groove 41. When the slide plate 42 contacts the slider 45, the buoyancy of the float 43 pushes the slider 45 to squeeze the spring column 46 and the alarm switch 47.

[0031] Three groups of support plates 51 are symmetrically arranged on the side of the floating plate 43 . The support plates 51 are rotatably connected to the rotating rods 52 . Connecting pipes 53 are equidistantly arranged on the sides of the rotating rods 52 . The connecting pipes 53 are arranged on the inner sides of the support plates 51 .

[0032] The flow rate detection mechanism 5 includes a paddle 54 and a speed detector 55. The paddles 54 are arranged at equal angles on the side of the connecting pipe 53. Two speed detectors 55 are symmetrically arranged on the side of the rotating rod 52. The speed detector 55 is arranged between the two groups of support plates 51. When the device is in use, the water flow impacts the paddle 54 during the water discharge process, thereby driving the rotating rod 52 to rotate, and at the same time driving the speed detector 55 to rotate. When the speed of the rotating rod 52 slows down, the filter screen 2 is blocked by debris. The staff can observe through the speed detector 55, which is convenient for the staff to clean the filter screen 2 in time.

[0033] When the utility model is in use, firstly the second positioning bolt 49 is rotated so that the second positioning bolt 49 is no longer in contact with the slide groove 41, at which time the housing 44 can be slid, and the height of the housing 44 can be adjusted as needed to trigger the blocking mechanism 3. When the water level rises, the floating plate 43 rises by buoyancy, and at the same time drives the slide plate 42 to slide inside the slide groove 41. When the slide plate 42 contacts the slider 45, the slider 45 is pushed by the buoyancy of the floating plate 43 to squeeze the spring column 46 and the alarm switch 47.

[0034] The alarm switch 47 triggers the driving motor 31, which drives the threaded rod 32 to rotate. During the rotation of the threaded rod 32, the river gate plate 33 is driven to slide and rise inside the frame 1;

[0035] During the water discharge process, the water flow impacts the blade 54, thereby driving the rotating rod 52 to rotate, and at the same time driving the speed detector 55 to rotate. When the speed of the rotating rod 52 slows down, the filter screen 2 is blocked by debris. The staff can observe through the speed detector 55, which is convenient for the staff to clean the filter screen 2 in time.

[0036] During the long-term use of the device, the waterproof plate 34 can be dismantled directly by removing the first positioning bolt 35 in the dry season, so that the waterproof layer and other materials can be re-sprayed without dismantling the entire device, thereby improving the overall convenience of the device.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
