[0002] A water conservancy project is a project that helps human behavior through the rational utilization of natural resources, which also includes water quality monitoring work. The water quality monitoring work is to collect water samples scientifically and reasonably, which can truly and accurately reflect the water environment quality status, and better provide a scientific basis for water environment management, pollution source control, environmental planning, etc.

[0003] When sampling water sources, sampling at the most active water source location can obtain the best measurement of the water environment quality. In a river, due to the setting of a water conservancy gate, an artificial height difference appears in the river, which makes the water body activity at this position the highest.

[0004] When sampling at a water conservancy gate, due to the setting of the river height difference, the water flows towards the lower place. When the sampling device is directly buried in the water body, it will bear a high impact force, which causes the sampling device to be washed away under the impact of the water flow, affecting the sampling work.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

Detailed implementation mode

[0022] The following combines the drawings and embodiments to describe the present utility model in detail.

[0023] A sampling device provided on a water gate, as Figure 1-2 shown, includes a fixed strip 1 fixed on the main rail of the gate. The fixed strip 1 is fixed at the side wall position of the main rail of the gate, which can avoid affecting the closing of the gate leaf. The fixed strip 1 is fixed relative to the main rail of the gate, which can facilitate the installation of the sampling device and prevent the sampling device from being washed away.

[0024] As Figure 1-3 shown, a first chute 2 is opened on the fixed strip 1. A connecting seat 3 is slidably connected to the fixed strip 1 at the position of the first chute 2. The connecting seat 3 is used to install the collection cylinder 5. A placing groove 4 is provided on the connecting seat 3. Through the setting of the placing groove 4, while the collection cylinder 5 can be installed, a rotating space is provided for the collection cylinder 5. After the collection cylinder 5 is installed on the connecting seat 3, the connecting seat 3 moves downward and submerges into the river. Under the scouring action of the water flow, the collection cylinder 5 will rotate.

[0025] As Figure 1-4 shown, the top of the collection cylinder 5 is conical. A baffle 6 is fixedly connected to the periphery of the collection cylinder 5. The conical setting is streamlined when bearing the water flow scouring. Due to the different resistances borne by different positions of the collection cylinder 5 during the water flow scouring and the collection cylinder 5 will rotate on the connecting seat 3. A counterweight is provided at the bottom of the collection cylinder 5. The counterweight will tilt backward under the drive of the water flow during the water entry process, resulting in the bottom position of the collection cylinder 5 tilting backward. After the collection cylinder 5 is completely submerged in water, the collection cylinder 5 is driven by the counterweight and rotates to an approximately horizontal state. Through the conical setting at its top, the water flow scouring effect can be reduced, making the collection cylinder 5 more stable. A baffle 6 is fixedly connected to the periphery of the collection cylinder 5. The baffle 6 is frustum-shaped. After the water flow and gravel are diverted at the top of the conical collection cylinder 5, the baffle 6 can further expand the diversion effect, making the large particle gravel be driven farther. When the collection cylinder 5 samples, it is submerged in the river. Water can quickly enter the collection cylinder 5 through the water inlet hole 7 by means of pressure difference to achieve the sampling purpose.

[0026] As Figure 1-3As shown, an extension plate 8 is fixedly connected to the lower side of the connecting seat 3. Through the arrangement of the extension plate 8, the space for storing the collection cylinder 5 is increased, and it can rotate more easily with the water flow in the river channel. A second chute 9 and an insertion chute 10 communicating with the second chute 9 are provided on the extension plate 8. A connecting column 11 for sliding into the insertion chute 10 is fixedly connected to the side wall of the collection cylinder 5. During installation, the connecting column 11 is pushed into the insertion chute 10 and approaches the second chute 9. After the connecting column 11 is within the range of the second chute 9, it moves downward under the gravity of the collection cylinder 5. When the collection cylinder 5 enters the river channel, it can slide to a certain extent in the second chute 9 to buffer the impact of the water flow.

[0027] As Figure 2 shown, a clamping groove is provided at the position of the extension plate 8 where the insertion chute 10 is located, and a clamping block 12 is clamped on the clamping groove. After the clamping block 12 is inserted, the insertion chute 10 is disconnected, and the collection cylinder 5 cannot fall out of the insertion chute 10.

[0028] As Figure 3-4 shown, a filter plate 13 is fixedly connected to the outside of the collection cylinder 5. Through the arrangement of the filter plate 13, the liquid entering the collection cylinder 5 is preliminarily filtered, reducing large impurities in the liquid that affect water quality monitoring. The filter plate 13 is clamped with the baffle 6, which can ensure that the filter plate 13 blocks the water inlet end of the baffle 6, ensuring the filtering effect and improving the overall connectivity.

[0029] As Figure 1-2 shown, the traction member includes an adjustment seat 14 fixedly connected to the top of the fixed strip 1, a winding drum 15 rotatably connected to the adjustment seat 14, and a connecting rope 16 wound around the winding drum 15. By rotating the winding drum 15 on the adjustment seat 14, the scaling of the connecting rope 16 can be controlled. When the connecting rope 16 is released, the gravity of the collection cylinder 5 causes the connecting seat 3 to move downward. When the connecting rope 16 is retracted, the connecting seat 3 is pulled and moves upward.

[0030] As Figure 1-2 shown, the first chute 2 is provided on both sides of the fixed strip 1 and is symmetrically arranged based on the central axis of the fixed strip 1. Through the first chutes 2 provided on both sides, the connecting seat 3 is limited on both sides after being inserted, reducing the influence of the water flow and preventing the connecting seat 3 from falling off.

[0031] As Figure 1-2 shown, a triangular boss 17 is fixedly connected to the connecting seat 3. The triangular boss 17 is located in the first chute 2 and one of its right-angled sides is in contact with the inner wall of the first chute 2. When the connecting seat 3 slides up and down, the triangular boss 17 can push the gravel out of the first chute 2 to prevent the stones from being stuck during sliding.

[0032] As Figure 3-4As shown in the figure, the counterweight includes a rope body 18 provided at the bottom end of the connecting seat 3 and a stabilizing block 19 fixedly connected to one end of the rope body 18 away from the connecting seat 3. The buoyancy of the stabilizing block 19 in the water body is equal to its gravity, and the stabilizing block 19 floats in the water body. When the stabilizing block 19 is placed in the river, the flowing water of the river pushes the stabilizing block 19, causing the stabilizing block 19 to move backward and drive the collecting cylinder 5 to tilt, thereby realizing the orientation adjustment of the collecting cylinder 5.

[0033] Working principle:

[0034] Push the connecting column 11 into the placement chute 10 and approach the second chute 9. After the connecting column 11 is within the range of the second chute 9, it moves downward under the gravity of the collecting cylinder 5. When the collecting cylinder 5 enters the river channel, it can slide to a certain extent in the second chute 9 to buffer the impact force of the water flow. After the clamping block 12 is placed, the placement chute 10 is disconnected, and the collecting cylinder 5 cannot slide from the second chute 9 into the placement chute 10 and fall out.

[0035] After the installation of the collecting cylinder 5 is completed, rotate the winding drum 15 to release the connecting rope 16. Under the gravity of the collecting cylinder 5, the connecting seat 3 moves downward and immerses in the river. Under the scouring of the river, the stabilizing block 19 is pushed, moves backward and drives the collecting cylinder 5 to tilt. Through the conical setting at the top of the collecting cylinder 5, the scouring effect of the water flow can be reduced, making the collecting cylinder 5 more stable. A baffle 6 is fixedly connected to the outer periphery of the collecting cylinder 5, and the baffle 6 is arranged in a frustum shape. After the water flow and stones are diverted at the top of the conically arranged collecting cylinder 5, the baffle 6 can further expand the diversion effect, making the large-particle stones be driven farther. When the collecting cylinder 5 takes a sample and is in the river channel, water can quickly enter the collecting cylinder 5 through the pressure difference to achieve the sampling purpose.

[0036] After the sampling is completed, rotate the winding drum 15 to pull up the connecting seat 3. After the collecting cylinder 5 leaves the river, it rotates under the action of gravity to avoid the liquid pouring out. The staff removes the collecting cylinder 5 on the connecting seat 3 to complete the sampling.

[0037] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
