Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water meter safety inspection and maintenance device for water conservancy and hydropower projects. Background Technology

[0002] Water meters for water conservancy projects are instruments used to measure the total water flow in water conservancy projects. They come in various types, including pointer type, dial type, and intelligent remote transmission type. Installed in locations that are easy to read, maintain, and manage, they play a vital role in water conservancy projects. Their accurate measurement and effective management are of great significance for ensuring the efficient operation of water conservancy projects and the sustainable use of water resources. Therefore, water meters often need to be inspected and maintained.

[0003] Chinese patent document CN111982252 A discloses a water meter testing platform, including a test bench with a cavity at its rear. The cavity includes a circulating water flow pump, a temperature-controlled water tank, a water storage tank, an electronic scale, a water flow sensor module, and a controller. A limiting rail is located at the upper end of the test bench, with a first moving structure and a second moving structure movably connected to its upper ends. The circulating water flow pump draws water from the temperature-controlled water tank, which then flows through the outlet of the second moving structure to complete the water flow circulation. This water meter testing platform utilizes the influence of water flow temperature on the accuracy of the water meter, predicts the water meter's performance in extremely harsh environments, and further demonstrates the water meter's performance accuracy relative to different water pressure peaks over the entire experimental period. It also assesses the impact of different impact pressures on the water meter during the instantaneous impact, thus utilizing the varying impact pressures to test the water meter's performance. The above technical solution has the following drawbacks in use: When water enters the water meter during use, water meter maintenance is required. The impact of the water can cause the water meter to shift position, which affects the maintenance work and results in poor stability. In addition, it is inconvenient to remove the water meter after maintenance.

[0004] Therefore, there is an urgent need to provide a water meter safety inspection and maintenance device for water conservancy and hydropower projects to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water meter safety inspection and maintenance device for water conservancy and hydropower projects.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a water meter safety inspection and maintenance device for water conservancy and hydropower projects, including an inspection platform, a placement platform fixedly installed on the surface of the inspection platform, and a meter body movably placed inside the placement platform; and further comprising:

[0030] In this embodiment: the sleeve 11 enables the lifting mechanism 6 to stably push the watch body 3 out of the placement platform 2, the slide groove 12 facilitates the clamping mechanism 5 to stably clamp the watch body 3 and the surfaces of the water inlet pipe 31 and the water outlet pipe 32, the support plate 13 provides support for the drive mechanism 4, and the limiting groove 14 makes the threaded rod 61 more stable when rotating.

[0034] In this embodiment: the inlet pipe 31 and the outlet pipe 32 facilitate the passage of water during testing, and the pipe groove 21 provides support for the inlet pipe 31 and the outlet pipe 32.

[0035] A drive mechanism 4 is fixedly installed on the lower surface of the inspection platform 1, a clamping mechanism 5 is slidably connected to the surface of the inspection platform 1, and a lifting mechanism 6 is slidably connected inside the inspection platform 1.

[0036] like Figure 3 As shown, the drive mechanism 4 includes a servo motor 41, which is fixedly mounted on the surface of a support plate 13 on one side. The output end of the servo motor 41 is connected to a bidirectional lead screw 42, which is rotatably connected between the two support plates 13. A first bevel gear 43 is fixedly mounted on the surface of the bidirectional lead screw 42.

[0037] In this embodiment: the servo motor 41 is started, the bidirectional lead screw 42 rotates, so that the clamping mechanism 5 can clamp the watch body 3. Through the meshing of the first bevel gear 43 and the second bevel gear 62, the threaded rod 61 rotates, which facilitates the lifting mechanism 6 to lift the watch body 3.

[0038] like Figure 3 As shown, the clamping mechanism 5 includes two first clamps 51. The first clamps 51 are slidably connected to the surface of the inspection table 1. A connecting rod 52 is fixedly installed on the surface of the first clamps 51. A second clamp 53 is fixedly installed at the end of the connecting rod 52. The first clamps 51 are in movable contact with the surfaces of the water inlet pipe 31 and the water outlet pipe 32. The second clamp 53 is in movable contact with the surface of the meter body 3. A moving rod 54 is fixedly installed on the lower surface of the first clamps 51. The moving rod 54 is slidably connected inside the slide groove 12. A first threaded sleeve 55 is fixedly installed at the end of the moving rod 54. The first threaded sleeve 55 is threadedly connected to the surface of the bidirectional lead screw 42.

[0039] In this embodiment: when the bidirectional lead screw 42 rotates, the two moving rods 54 are brought closer together by the setting of the first screw sleeve 55, which further drives the two first clamps 51 to move closer together, thereby fixing and clamping the water inlet pipe 31 and the water outlet pipe 32. When the first clamps 51 move closer together, the two second clamps 53 move closer together by the connection of the connecting rod 52, thereby fixing and clamping the meter body 3 by the second clamps 53.

[0040] like Figure 2As shown, the lifting mechanism 6 includes a threaded rod 61, which is rotatably connected inside the sleeve 11. A limiting ring 65 is fixedly installed on the surface of the threaded rod 61, and the limiting ring 65 is rotatably connected inside the limiting groove 14.

[0041] In this embodiment: after the watch body 3 is repaired, the first bevel gear 43 and the second bevel gear 62 mesh, and the bidirectional lead screw 42 rotates, driving the threaded rod 61 to rotate. The first chuck 51 and the second chuck 53 move away from each other, thereby causing the second threaded sleeve 63 to move upward inside the sleeve 11, and further causing the top plate 64 to move upward inside the placement groove 22, lifting the repaired watch body 3 from inside the placement groove 22, making it easy for the staff to pick it up.

[0042] In use, the meter body 3 is placed on the surface of the top plate 64. The servo motor 41 is started, and the bidirectional lead screw 42 rotates. Through the meshing of the first bevel gear 43 and the second bevel gear 62, the threaded rod 61 rotates clockwise, and the second threaded sleeve 63 moves downward, thereby moving the top plate 64 into the placement platform 2 and the meter body 3 into the placement slot 22. At the same time, the setting of the first threaded sleeve 55 brings the two moving rods 54 closer together, further moving the two first clamps 51 closer together, thereby connecting the water inlet pipe 31 and the water outlet pipe. When the first clamp 51 approaches, the two second clamps 53 approach each other through the connection of the connecting rod 52, thereby fixing the meter body 3 with the second clamps 53. When the meter body 3 is repaired, the servo motor 41 starts again, the bidirectional lead screw 42 reverses, the first clamp 51 moves away from the surface of the meter body 3, and the second clamp 53 moves away from the surface of the inlet pipe 31 and the outlet pipe 32, thus releasing the clamp on the meter body 3. The top plate 64 lifts the meter body 3 from inside the placement platform 2, and the staff can then take it out.
