Description

Technical Field

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

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, also known as a water project. Water is an indispensable precious resource for human production and life. However, its natural state does not fully meet the needs of humans. Only by building water conservancy projects can water flow be controlled, flood disasters be prevented, and water volume be regulated and distributed to meet the water resource needs of people's lives and production. Water conservancy projects need to build different types of hydraulic structures such as dams, levees, spillways, sluice gates, water inlets, channels, aqueducts, raft channels, and fishways to achieve their goals. In the daily work of water conservancy projects, in order to understand the specific situation of water quality in the area, sampling equipment needs to be used to sample water to understand the specific water quality situation, and a water conservancy project plan is formulated according to the situation.

[0003] Common water quality sampling devices are generally installed on the hoisting, cross-arm or hook-lock structures on the ship, and then the sampling mechanism is immersed in the water for sampling. However, this type of water quality sampling device can only sample the water quality on the surface of the river. When used, the statistics and evaluation of the river water quality are not complete, resulting in deviation of the test results, which in turn affects the project quality and project progress. In order to improve the accuracy of sampling data, the sampling mechanism is lengthened so that it can penetrate deeper into the bottom of the water body to obtain more comprehensive data. However, in this way, since the sampling device is directly inserted into the water, the water body is in a static state when it is filled into the container, resulting in the suspension substances in the water not being fully mixed with the water body, reducing the representativeness of the water sample, and thus the obtained water quality sample is relatively single and cannot meet the work requirements of water quality sampling. Therefore, a water quality sampling device for water conservancy projects is proposed. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a water quality sampling device for water conservancy projects to solve the technical problem that the suspension substances in the water cannot be fully mixed with the water body when the water body is filled into the container, resulting in the reduction of the representativeness of the water sample.

A water inlet is opened inside the socket, and the water inlet is communicated with the inner cavity of the sampling box. Partition plates are inserted on both the upper and lower sides of the inner cavity of the sampling box, so that water samples can be taken separately from different depths of water.

[0014] Preferably, a drain pipe is connected to the inner side of the sampling box at the position above the partition plate, and a sealing cover is screwed at the outer end of the drain pipe.

[0016] (III) Beneficial effects

Furthermore, it can drive the gear plate and the sampling box to rotate circumferentially, and at the same time, the sampling box can be changed in the left and right directions. When the sampling box is inserted into the water for sampling, the water body can be stirred first, so that the suspended substances in the water sample are fully mixed, improving the representativeness of the water sample, avoiding sampling deviation caused by water body stratification, enhancing the comprehensiveness of sampling. At the same time, stirring and stirring the water body can increase the oxygen content in the water body, which is beneficial to the growth and metabolism of microorganisms, thereby affecting the self-purification ability of the water body. And the deposited microorganisms can be stirred again to make them suspended, avoiding their long-term accumulation at the bottom of the water body, thus reducing the impact on water quality. This not only improves the quality of sampling, but also facilitates the subsequent treatment of water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention provides a technical solution, a water quality sampling device for water conservancy projects, including a triangular base 1, a mounting seat 2, a motor 3, a triangular limiting plate 4, a circular plate 5, a toothed disk 6, a slider 7, a toothed plate 8, a connecting shaft 9, a sampling box 10, a socket 11, a water inlet 12, a limiting rod 13, a triangular end 131, a trapezoidal end 132, a drain pipe 14, a plug board 15, a limiting hole 16, a partition plate 17, a through hole 18, a mounting block 19 and a bolt 20:

[0029] Please refer to Figure 1 , a mounting seat 2 is installed on the top of the triangular base 1. Please refer to Figure 2 , a motor 3 is installed at the middle position of the bottom of the mounting seat 2. Please refer to Figure 3 , the inside of the triangular base 1 is a hollow structure, and a circular plate 5 is installed at the middle position of the inner cavity top of the triangular base 1;

[0030] The triangular limiting plate 4 is installed at the inner sharp corners of the triangular base 1. The rotor of the motor 3 penetrates through the inside of the triangular base 1 and the circular plate 5, and a toothed disk 6 is coaxially installed at the bottom end of the rotor of the motor 3;

[0031] The sliders 7 are inserted on the outer sides of the inside of the triangular base 1. Tooth plates 8 are installed at the bottom ends of the sliders 7. The left and right ends of the tooth plates 8 are both semicircularly arranged. The inner sides of the tooth plates 8 are meshed with the toothed disk 6. Connecting shafts 9 are installed at the bottom ends of the tooth plates 8, and the bottom ends of the connecting shafts 9 are all connected to the sampling box 10.

Please refer to Figure 5, triangular ends 131 are installed at the left ends of the limiting rods 13, and trapezoidal ends 132 are installed at the right ends of the limiting rods 13. The inner sides of the triangular limiting plates 4 and the triangular ends 131 are both arc-shaped, and the outer end sharp corners of the triangular limiting plates 4 are all rounded. By driving the rotation of the toothed disc 6 by the motor 3, the toothed plate 8 and the slider 7 can be moved. When one side of the slider 7 passes through the trapezoidal end 132 of the limiting rod 13, it will push the limiting rod 13 to swing, causing the triangular end 131 of the limiting rod 13 to lift, so as to limit the other side of the slider 7, making the other side of the slider 7 slide into the position between the triangular limiting plate 4 and the circular plate 5, and then driving the toothed plate 8 and the sampling box 10 to rotate circumferentially, and at the same time making the sampling box 10 change its left and right orientation.

Installation blocks 19 are installed at positions corresponding to the insertion plates 15 on the top of the mounting base 2, and bolts 20 are screwed inside the installation blocks 19.

[0033] In this solution, the motor 3 drives the toothed disc 6 to rotate, so that the toothed plate 8 and the slider 7 can move. When the slider 7 on one side passes the trapezoidal end 132 of the limiting rod 13, it will be pushed to swing, so that the triangular end 131 of the limiting rod 13 is lifted, so that the slider 7 on the other side can be limited, so that the slider 7 on the other side slides into the position between the triangular limiting plate 4 and the circular plate 5, and then the toothed plate 8 and the sampling box 10 can be driven to rotate circumferentially, and at the same time, the sampling box 10 can be changed in left and right directions, so that when the sampling box 10 is inserted into the water for sampling , the water body can be stirred first to fully mix the suspended matter in the water sample, thereby improving the representativeness of the water sample, avoiding sampling deviation caused by water stratification, and improving the comprehensiveness of sampling. At the same time, stirring and stirring the water body can increase the oxygen content in the water body, which is beneficial to the growth and metabolism of microorganisms, thereby affecting the self-purification ability of the water body, and the deposited microorganisms can be re-stirred to suspend them, avoiding their long-term accumulation at the bottom of the water body, thereby reducing the impact on water quality, which not only improves the quality of sampling, but also facilitates the subsequent water quality treatment.
