Description

Technical Field

[0001] The utility model relates to the technical field of reservoir dams, in particular to a reservoir dam leakage flow meter. Background Art

[0002] The compactness of the earth-rock dam itself is limited, and the dam always has different degrees of leakage. When the water level upstream of the reservoir changes, the flow of water leaking from the dam will also change, and then it is necessary to measure the internal seepage and the upstream water level in real time, and this is when a flow meter is needed.

[0003] However, in actual use, due to the different water depths in the actual dam top channel, a measuring device that can be easily adjusted is needed to facilitate automatic adjustment according to the water level. At the same time, when in use, the water flow usually carries debris, such as aquatic plants, soil and other floating objects, which in turn affects the device inserted in the channel and the upstream basin, and affects the device's ability to adjust up and down with the water level. Therefore, the device needs to be able to effectively remove debris to avoid interference with measurement. Utility Model Content

[0004] The utility model aims to provide a reservoir dam leakage flow meter, which solves the problem that the existing reservoir dam flow meter is inconvenient to adjust according to different water level depths and inconvenient to remove crops attached to the outer wall.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reservoir dam leakage flow meter, comprising a fixed rod, a bottom plate and a top plate, wherein the bottom of the fixed rod is fixedly connected with the bottom plate, the top of the fixed rod is provided with a top plate, a rotating assembly is installed at one end of the top plate close to the fixed rod, a filter tube is sleeved on the top outer wall of the fixed rod, and a screw rod is provided through the inside of the fixed rod;

[0008] The outer wall of the screw rod used for rotation is rotatably connected with a threaded tube, and the outer wall of the bottom of the threaded tube is slidably connected with the inside of the fixed rod through a sliding block.

[0009] Preferably, a prismatic groove is provided inside the fixed rod, and the bottom outer wall of the movable tube is slidably connected to the inside of the prismatic groove through a movable block, a through hole is provided at the top of the fixed rod, and the outer wall of the movable tube and the through hole are slidably connected to each other.

[0010] Preferably, the sliding block is slidably connected to the inside of the prismatic sliding groove, and the outer wall of the screw rod is rotatably connected to the fixed rod and the bottom plate respectively through bearings.

[0011] Preferably, the top of one end of the base plate is fixed to the bottom of the fixed rod, a measuring meter is provided at the end of the base plate away from the fixed rod, and a driving motor is provided at the end of the bottom of the base plate close to the fixed rod, and the bottom of the screw rod passes through the interior of the fixed rod and the base plate and is fixed to the power output end of the driving motor.

[0012] Preferably, a scraper is provided on one side of the outer wall of the filter tube close to the center of the top plate, the top of the scraper is fixed to the top plate, and one side of the scraper is in contact with the outer wall of the filter tube, and a floating block is installed on the bottom of the top plate away from the filter tube.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. Under the action of the floating block, the top plate can be effectively driven to move to the top, so that it is at the top of the water surface. When the top plate moves to the top, the filter tube and the moving tube at the bottom can also be driven to move to the top, thereby realizing the driving of the moving block.

[0016] 2. The outer wall of the moving tube is blocked by the filter tube to prevent external debris and aquatic plants from directly contacting the moving tube, which can effectively prevent the moving tube from being blocked in its up and down movement. At the same time, when there are crops attached to the outer wall of the filter tube, the rotating assembly can be started, so that the rotating motor drives the driving gear to rotate, and the driving gear drives the rotating gear ring to rotate, so that the filter tube follows the rotation. Moreover, since the scraper is fixed to the top plate, the scraper can effectively remove the debris on the outer wall of the filter tube while it rotates, which can effectively keep it clean and avoid affecting the lifting.

[0027] like Figure 1-5As shown, a movable tube 501 is provided inside the filter tube 5 for blocking, and the movable tube 501 is slidably connected to the inside of the fixed rod 1, and the top of the filter tube 5 is rotatably connected to the outer wall of the top of the movable tube 501; the rotating component 4 for rotating includes a rotating gear ring 401 and a driving gear 402, the rotating gear ring 401 and the driving gear 402 are meshed with each other, and the rotating gear ring 401 and the top of the filter tube 5 are fixedly connected to each other; the outer wall of the screw rod 6 for rotating is rotatably connected to a threaded tube 602, and the bottom outer wall of the threaded tube 602 is slidably connected to the inside of the fixed rod 1 through a sliding block 601.

[0028] like Figure 4 , Figure 5 As shown, a prismatic groove 101 is provided inside the fixed rod 1, and the bottom outer wall of the movable tube 501 is slidably connected to the inside of the prismatic groove 101 through a movable block 503, a through hole 102 is provided at the top of the fixed rod 1, and the outer wall of the movable tube 501 and the through hole 102 are slidably connected to each other, and a scraper 502 is provided on one side of the outer wall of the filter tube 5 near the center of the top plate 3, the top of the scraper 502 is fixed to the top plate 3, and one side of the scraper 502 is in contact with the outer wall of the filter tube 5, and the bottom of the top plate 3 is away from the filter tube 5. A floating block 301 is installed on one side. Under the action of the floating block 301, the top plate 3 can be effectively driven to move toward the top, so that it is at the top of the water surface. When the top plate 3 moves toward the top, the filter tube 5 and the moving tube 501 at the bottom can also be driven to move toward the top, thereby realizing the driving of the moving block 503. The outer wall of the moving tube 501 can be blocked by the filter tube 5, thereby preventing external debris and aquatic plants from directly contacting the moving tube 501, and effectively preventing the moving tube 501 from being blocked in its up and down movements.

[0029] like Figure 3 , Figure 4 As shown, the sliding block 601 is slidably connected with the inside of the prismatic slide groove 101, and the outer wall of the screw rod 6 is rotatably connected with the fixed rod 1 and the base plate 2 respectively through bearings, the top of one end of the base plate 2 is fixed to the bottom of the fixed rod 1, a measuring meter 202 is provided at the end of the base plate 2 away from the fixed rod 1, and a driving motor 201 is provided at the end of the bottom of the base plate 2 close to the fixed rod 1, the bottom of the screw rod 6 passes through the fixed rod 1 and the inside of the base plate 2 and is fixed to the power output end of the driving motor 201, and the driving motor 201 drives the screw rod 6 to rotate. Since the screw rod 6 and the threaded tube 602 rotate with each other, and the threaded tube 602 is slidably connected with the prismatic slide groove 101 through the sliding block 601, the rotation of the screw rod 6 drives the sliding block 601 to move to the top through the threaded tube 602, and the sliding block 601 moves to the top.

[0031] Working principle: When in use, the bottom plate 2 of the device can be installed on the bottom of the water. At the same time, under the action of the floating block 301, the top plate 3 can be effectively driven to move to the top, so that it is at the top of the water surface. When the top plate 3 moves to the top, it can also drive the filter tube 5 and the moving tube 501 at the bottom to move to the top, thereby realizing the driving of the moving block 503.

Since the screw rod 6 and the threaded tube 602 rotate with each other, and the threaded tube 602 is slidably connected with the prismatic slide groove 101 through the sliding block 601, the screw rod 6 rotates through the threaded tube 602 to drive the sliding block 601 to move to the top, and then the sliding block 601 moves to the top, so that it pushes the moving block 503, thereby realizing the pushing of the moving tube 501, and realizing the driving of the position of the top plate 3, which is convenient for adjustment.

[0032] When in use, the outer wall of the mobile tube 501 can be blocked by the filter tube 5, thereby preventing external debris and aquatic plants from directly contacting the mobile tube 501, and effectively preventing the up and down movement of the mobile tube 501 from being blocked.
