Technical Field

[0001] The utility model relates to the technical field of water sampling devices, in particular to a water sampling device for water conservancy projects. Background Art

[0002] Water conservancy projects refer to various types of projects (including new construction, expansion, reconstruction, reinforcement, repair and demolition projects) such as flood control, drainage, irrigation, hydroelectric power generation, water diversion and supply, tidal flat management, soil and water conservation, and water resource protection, as well as their supporting and ancillary projects. Water resource protection requires water quality sampling and testing. Manually lifting and pulling sampling buckets for sampling is time-consuming and labor-intensive, and not convenient or flexible enough.

[0003] The patent publication (publication number CN219996618U) discloses a water conservancy engineering sampling device, including a base and a sampling bucket. A column is fixedly provided on the top of the base, and a telescopic frame is fixedly provided on the column... The sediment in the water can be filtered to prevent the sediment in the water from clogging the device, causing damage to the device or even reducing its service life.

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.

[0029] See also Figure 1-8 The utility model discloses a water sampling device for a water conservancy project, comprising a fixing seat 1, a fixing arm 11 is arranged on one side of the fixing seat 1, a storage tube 12 is arranged at the bottom of one end of the fixing arm 11, an extension arm 13 is arranged inside the fixing arm 11 for movement, a traction rope 16 is arranged inside the extension arm 13 for movement, one end of the traction rope 16 extends to the interior of the storage tube 12 and is provided with a sampling bucket 2.

[0030] A sampling chamber 22 is provided inside the sampling barrel 2, a servo motor 23 and a turntable 24 driven by the servo motor 23 are provided inside the sampling chamber 22, at least one sampling cup 25 is movably connected to the turntable 24 through a block 241, a floating plate 251 is provided inside the sampling cup 25, a sampling tube 26 with one end extending above one of the sampling cups 25 and an electric push rod 27 located on one side of the sampling tube 26 are provided on one side of the inner wall of the sampling barrel 2, a sealing plate 28 driven by the electric push rod 27 is provided on one side of the sampling barrel 2, a filter screen 261 connected to the sampling tube 26 is also embedded on one side of the sampling barrel 2, and the sealing plate 28 is located on one side of the filter screen 261.

[0031] Specifically, a conical sealing ring 203 is provided on one side of the sampling barrel 2 and is located outside the filter screen 261. Figure 7 The outer ring of the conical sealing ring 203 is inclined, so when the electric push rod 27 pushes the sealing plate 28, it will not get stuck.

[0032] Specifically, two limit blocks 29 are symmetrically arranged on one side of the sampling barrel 2, and the sealing plate 28 is movably stuck between the two limit blocks 29. A brush plate 281 is arranged at one end of the sealing plate 28, and a rubber pad is arranged on the side of the sealing plate 28 opposite to the sampling barrel 2, and bristles are arranged on one side of the brush plate 281. The setting of the brush plate 281 can clean the filter net 261 once when the sealing plate 28 pushes the brush plate 281, thereby preventing impurities in the water such as aquatic plants from clogging the filter net 261.

[0033] Specifically, a movable hole is opened on one side of the inner wall of the sampling barrel 2 and a sealing gasket 202 is arranged inside the movable hole. A driving block 271 is arranged at the output end of the electric push rod 27. One end of the driving block 271 passes through the sealing gasket 202 and is movably connected with the inside of the sealing plate 28. The sealing gasket 202 can be stretched to cover the movable hole without affecting the movement of the driving block 271. The driving block 271 is movably connected with the sealing plate 28, and the sealing plate 28 is limited by the limiting block 29. The driving block 271 is only responsible for transmitting the sealing plate 28, thereby preventing the sealing plate 28 from contacting the conical sealing ring 203.

When in use, first push the extension arm 13, then start the electric push rod 27 to drive the sealing plate 28 to cover the filter 261. When the sampling bucket 2 is lowered to the specified water level, start the electric push rod 27 to retract, and water enters the interior of the sampling cup 25 through the filter 261 and the sampling tube 26. The floating plate 251 drives the screw 253 to rise and trigger the induction with the sensor 201, then start the electric push rod 27 to drive the sealing plate 28 to cover the filter 261, and at the same time start the servo motor 23 to drive the turntable 24 to rotate, so that the next unused sampling cup 25 enters the sampling position. The servo motor 23 can accurately control the rotation angle and can be adapted to different numbers of sampling cups 25. See Figure 8 The number of the sampling cups 25 is four, and the servo motor 23 drives the turntable 24 to rotate 90 degrees each time.

[0036] Specifically, a storage cover 131 for covering the storage tube 12 is provided at one end of the extension arm 13, and a winding tube 14 is provided at the other end of the extension arm 13. The storage cover 131 is used to cover the outlet of the storage tube 12. When the sampling bucket 2 is lifted into place, it will be hidden on one side of the storage cover 131. The user pulls the extension arm 13 to drive the sampling bucket 2 to be stored inside the storage tube 12.

[0037] Specifically, a winding wheel is provided inside the winding drum 14, and the end of the traction rope 16 away from the sampling bucket 2 is wound on the surface of the winding wheel. A crank 15 with one end extending to the outside of the winding drum 14 is provided on both sides of the winding wheel. The winding wheel is rotated by the crank 15, and the traction rope 16 can be wound and unwound according to the rotation direction.

[0039] In summary, the water sampling device for water conservancy projects drives the sealing plate 28 to cover the filter screen 261 through the electric push rod 27, so that the water flow can automatically flow into the interior of the sampling area, and there will be no residue after each sampling. The sensor 201 cooperates with the adjustable screw 253 to control the water intake. The servo motor 23 drives the turntable 24 to rotate.
