DETAILED DESCRIPTION

[0017] Reference Figures 1 to 4 As shown, the utility model provides a water quality detection sampling device for environmental monitoring, comprising: a bottom plate 1 and a storage box 8, wherein the bottom plate 1 and the top plate 11 are symmetrically connected with a reinforcement column 14, and the outer side of the reinforcement column 14 is fixedly connected with an interception net 13, and the middle part of the upper surface of the bottom plate 1 is fixedly connected with the storage box 8, and the upper surface of the storage box 8 is fixedly connected with a power assembly 10, and at the same time, the storage box 8 is movably connected with a transmission shaft 5 through a sealed bearing, and the upper end of the transmission shaft 5 is connected to the motor in the power assembly 10 through a coupling, and a loading and unloading port is provided on the side of the storage box 8, and the loading and unloading port is provided. A secondary sealing groove and a main sealing groove are respectively provided on the side and bottom of the unloading port, and the position of the surface of the closing plate 3 relative to the main sealing groove and the secondary sealing groove corresponds to the main sealing plate 2 and the secondary sealing plate 15, and the closing plate 3 is fixedly connected to the loading and unloading port through the fixing plate 9, and the fixing plate 9 is fixedly connected to the upper surface of the storage box 8 by bolts, and at the same time, the side of the transmission shaft 5 is symmetrically connected to the partition plate 6, and the sampling box 4 is slidably connected to the storage box 8 through the partition plate 6, and the upper surface of the sampling box 4 is fixedly connected to the sealing gasket 7, and the through-hole at the top of the sampling box 4 is connected to the liquid injection port at the top of the storage box 8.

[0018] In this embodiment, when it is necessary to monitor the water area environment, after the sampling device is put into the water area to be tested for water quality, the depth of the sampling device falling into the water area is controlled by the fixing rope. When the sampling device moves to the designated depth, the switch of the power component 10 is started. The servo motor in the power component 10 drives the transmission shaft 5 to rotate through the coupling, and the transmission shaft 5 pushes the six sampling boxes 4 in the storage box 8 to rotate synchronously through the partition plate 6. Each time the switch of the power component 10 is pressed once, the servo motor in the power component 10 can drive the transmission shaft 5 to rotate by 15 degrees. Therefore, the liquid injection port of the storage box 8 can communicate with the through hole at the top of a group of sampling boxes 4. At this time, the water sample in the area to be collected can flow into this group of sampling boxes 4. After the worker waits for a period of time, the switch of the power component 10 is pressed again. Therefore, the power component 10 pushes the six sampling boxes 4 to rotate by 15 degrees again through the transmission shaft 5 and the partition plate 6, so that the liquid injection port of the storage box 8 is sealed by the sealing gasket 7. Then the worker can adjust the position of the sampling device through the fixing rope, which is convenient for the collection of the next water sample. Thus, the sampling device can collect and temporarily store the water samples at multiple positions in a round trip, improving the efficiency of water quality detection sampling. After that, during the process of taking out the water sample, first remove the fixing plate 9 to release the restriction between the sealing plate 3 and the storage box 8, and then remove the sealing plate 3, so that the sampling box 4 can be directly exposed to the outside through the loading and unloading port. After taking out a group of sampling boxes 4, start the switch of the power component 10, so that the transmission shaft 5 moves the next group of sampling boxes 4 to the loading and unloading port through the partition plate 6, improving the loading and unloading efficiency of the sampling box 4. At the same time, the shell of the power component 10 is made of waterproof material, and the power component 10 is internally provided with a storage battery, thus ensuring that the power component 10 can operate normally.

At the same time, the setting of the fixing rod facilitates the fixed connection of the fixing rope to the sampling device, and the control line of the power component 10 is also convenient to be fixed on the surface of the fixing rope.

The plurality of reinforcing columns 14 are all in a long strip structure, and the horizontal cross section of the reinforcing column 14 is in a fan-shaped ring structure. At the same time, the upper end of the reinforcing column 14 is fixedly connected to the top plate 11 by bolts.

[0022] In this embodiment, if Figure 1 and Figure 2 The provision of the reinforcement column 14 can effectively enhance the overall structural strength of the sampling device, thereby reducing the probability of the sampling device being damaged due to impact by foreign objects or fish during underwater sampling.

[0023] As a preferred embodiment, the interception net 13 is an overall C-shaped structure. The interception net 13 is fixedly connected to the outer side of the reinforcement column 14 by a snap buckle, and the interception net 13 and the reinforcement column 14 are combined together to form a cylindrical structure. At the same time, the axial length of the interception net 13 is adapted to the length of the reinforcement column 14.

[0024] In this embodiment, if Figure 1 and Figure 2 The interception net 13 is connected by a snap-fit ​​connection, which can improve the loading and unloading efficiency of the interception net 13. At the same time, the setting of the interception net 13 can also prevent foreign objects or fish in the water from directly colliding with the power component 10 and the storage box 8, thereby reducing the probability of failure of the sampling device.

[0025] As a preferred embodiment, the storage box 8 has a cylindrical structure, the loading and unloading port opened on the side of the storage box 8 has a rectangular structure, and the two sets of secondary sealing grooves symmetrically opened on both sides of the loading and unloading port are both long strip structures, and the main sealing groove opened at the bottom of the loading and unloading port is a fan-shaped structure. At the same time, the cross-section of the sealing layer fixedly connected in the main sealing groove and the secondary sealing groove is a concave structure.

[0026] In this embodiment, if Figure 1 and Figure 2 The sealing layer is made of soft rubber material, which can help enhance the sealing effect of the connection between the main sealing plate 2 and the main sealing groove, and the auxiliary sealing plate 15 and the auxiliary sealing groove, thereby reducing the probability of external liquid penetrating into the storage box 8.

[0027] As a preferred embodiment, the closing plate 3 is in a fan-shaped structure, the upper surface of the closing plate 3 and the upper surface of the storage box 8 are in the same plane, and the fixing plate 9 is in a fan-shaped structure, the lower surface of the fixing plate 9 is fixedly connected to the fastening layer, and the sizes of the injection port and the through port opened in the storage box 8 are matched.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The fastening layer is made of soft rubber material, which can help enhance the sealing of the contact surface between the fixing plate 9, the closing plate 3 and the storage box 8 during the process of the fixing plate 9 fixing the closing plate 3, and further reduce the probability of external liquid flowing into the storage box 8 through the loading and unloading port.

[0029] As a preferred embodiment, the arc surface of the transmission shaft 5 is circumferentially surrounded by six groups of partition plates 6 that are fixedly connected at equal intervals. The six groups of partition plates 6 are all adapted to the inner cavity size of the storage box 8, and the horizontal cross-section of the sampling box 4 is a fan-shaped structure. The sizes of the sampling box 4 and the two adjacent groups of partition plates 6 are adapted to each other. At the same time, the sealing gasket 7 fixedly connected to the upper surface of the sampling box 4 is a fan-shaped structure, and the upper surface of the sealing gasket 7 and the upper surface of the partition plate 6 are in the same plane.

[0030] In this embodiment, if Figure 1 and Figure 4 The sealing gasket 7 is made of soft rubber material, which can help enhance the sealing of the connection between the upper surface of the sampling box 4 and the top of the storage box 8. Therefore, after the injection port and the through-port are disconnected, it can prevent the liquid in the sampling box 4 from accidentally flowing out, or the external liquid from flowing into the storage box 8 through the injection port, thereby ensuring that the six groups of sampling boxes 4 have good mutual independence, so that the sampling device can store multiple groups of water samples at the same time.
