Description

Technical Field

[0001] This utility model relates to the field of synchronous water sample collection technology, specifically a device for synchronous water sample collection in areas with different flow velocities in a river. Background Technology

[0002] In water resource management, water environment improvement projects, scientific research, and water quality testing, it is often necessary to collect water samples from areas with different flow velocities. When the flow velocity is slow, pollutants stay at the sampling section for a longer time, resulting in a higher concentration of pollutants in the water sample. Conversely, when the flow velocity is too fast, the concentration of pollutants may be lower. To improve sampling accuracy, water samples from multiple areas with different flow velocities are usually collected for comparison.

[0003] Currently, existing technologies typically utilize self-priming pumps and pipelines to extract water samples from different river sections one by one. However, this process cannot guarantee the synchronicity of water sample collection, thus affecting the accuracy of water quality testing. Therefore, it is necessary to propose a device for synchronous water sample collection in river regions with different flow velocities. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the inability of existing water sampling devices to guarantee synchronous sampling in different river sections, which affects water quality testing, this invention proposes a synchronous water sampling device for river areas with different flow velocities.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a device for synchronous collection of water samples in different flow velocity areas of a river, including a counterweight rod, a connecting rod provided at the top of the counterweight rod, a crossbar inserted into one side of the connecting rod, a traction rod provided at one end of the crossbar, a synchronous sampling mechanism provided at one end of the traction rod, and an emptying pipe provided at one end of the synchronous sampling mechanism;

[0006] The synchronous sampling mechanism includes a fixed base, which is fixedly connected to the end of the traction rod. A waterproof sleeve is fixedly connected to one side of the fixed base. A sampling tube is provided at one end of the fixed base. A sampling tank is provided at the bottom of the waterproof sleeve. One end of the sampling tube extends into the inner cavity of the sampling tank. A piston is provided in the inner cavity of the sampling tube. An electric push rod is provided at one end of the piston. One end of the drain pipe is fixedly connected to one side of the sampling tank. A water level sensor is provided in the inner cavity of the sampling tank.

[0007] Preferably, a flow rate sensor is provided at one end of the fixing base, and a plug is provided at the other end of the fixing base, with the end of the plug inserted into the end of the sampling tube.

[0008] Preferably, the electric push rod is fixedly connected to the inner cavity of the waterproof sleeve, and the telescopic shaft of the electric push rod passes through the inner cavity of the sampling tube and is fixedly connected to one end of the piston.

[0009] Preferably, a discharge pipe is provided on the side of the sampling tube near the piston, and one end of the discharge pipe extends into the inner cavity of the sampling tank.

[0010] Preferably, a sealing sleeve is provided at one end of the sampling tube near the electric push rod, and the telescopic shaft of the electric push rod passes through the sealing sleeve and is slidably connected to the sealing sleeve.

[0011] Preferably, one end of the drain pipe is fixedly connected to the end of the crossbar, and a one-way valve is fixedly connected to the end of the drain pipe.

[0012] Preferably, the top of the crossbar is provided with a through groove, and a bolt is provided in the middle of the connecting rod, the bolt passing through both ends of the through groove.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a counterweight and connecting rod to stably support a crossbar, enabling the crossbar to stably support the traction rod and the synchronous sampling mechanism as they penetrate the river water. In practice, synchronous sampling mechanisms can be set up at different flow velocity sections of the river. A control circuit controls the electric push rods in multiple sampling mechanisms to simultaneously pull the pistons, allowing water to flow from the sampling tube into the inner cavity of the sampling tank. The venting pipe works in conjunction with this to vent the air inside the sampling tank and balance the pressure inside the tank, ensuring a stable inflow of water. This achieves the effect of synchronous sampling at different flow velocity sections of the river, solving the problem that existing water sampling devices cannot guarantee synchronous sampling when sampling in different river sections, thus affecting water quality testing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a device for simultaneous water sample collection in river regions with different flow velocities. (Refer to...) Figures 1-5 A device for synchronously collecting water samples from different flow velocity areas of a river includes a counterweight rod 1, a connecting rod 2 at the top of the counterweight rod 1, a crossbar 21 inserted into one side of the connecting rod 2, a traction rod 22 at one end of the crossbar 21, a synchronous sampling mechanism 3 at one end of the traction rod 22, and a drain pipe 4 at one end of the synchronous sampling mechanism 3. The counterweight rod 1 and the connecting rod 2 stably support the crossbar 21 suspended above the river, allowing the traction rod 22 and the synchronous sampling mechanism 3 to penetrate into the water flow. In practice, synchronous sampling mechanisms 3 can be set up in different flow velocity areas of the river, and multiple synchronous sampling mechanisms 3 can be controlled by a control circuit to collect water samples synchronously. This allows water from different flow velocity areas of the river to flow into the synchronous sampling mechanism 3 simultaneously. The synchronous sampling mechanism 3 uses the drain pipe 4 to balance the internal pressure, ensuring a stable flow of water into the synchronous sampling mechanism 3, thereby achieving the purpose of synchronously collecting water samples from different flow velocity areas of the river.

[0025] The synchronous sampling mechanism 3 includes a fixed base 31, which is fixedly connected to the end of the traction rod 22. A waterproof sleeve 32 is fixedly connected to one side of the fixed base 31. A sampling tube 34 is provided at one end of the fixed base 31. A sampling container 37 is provided at the bottom of the waterproof sleeve 32. One end of the sampling tube 34 extends into the inner cavity of the sampling container 37. A piston 310 is provided in the inner cavity of the sampling tube 34. An electric push rod 39 is provided at one end of the piston 310. One end of the drain pipe 4 is fixedly connected to one side of the sampling container 37. A water level sensor 3 is provided in the inner cavity of the sampling container 37. 8. The piston 310 is pulled by the electric actuator 39. The piston 310 slides inside the sampling tube 34, so that the sampling tube 34 is connected to the sampling tank 37. This allows water to flow from the sampling tube 34 into the sampling tank 37. The water level sensor 38 is used to detect the water level in the sampling tank 37 in real time. After the predetermined water level is reached, the electric actuator 39 pushes the piston 310 again to close the sampling tube 34, thus completing the water sample collection. The fixed seat 31 and the waterproof sleeve 32 seal the water, thereby improving the waterproofness of the electric actuator 39.

[0026] Reference Figure 3 , Figure 4 and Figure 5 A flow rate sensor 33 is provided at one end of the fixed base 31, and a plug 35 is provided at the other end of the fixed base 31. The end of the plug 35 is inserted into the end of the sampling tube 34. An electric push rod 39 is fixedly connected to the inner cavity of the waterproof sleeve 32. The telescopic shaft of the electric push rod 39 passes through the inner cavity of the sampling tube 34 and is fixedly connected to one end of the piston 310. A feed pipe 36 is provided on the side of the sampling tube 34 near the piston 310. One end of the feed pipe 36 extends into the inner cavity of the sampling tank 37. A sealing sleeve 311 is provided on the end of the sampling tube 34 near the electric push rod 39. The telescopic shaft of the electric push rod 39 passes through the sealing sleeve 311 and is connected to the sealing sleeve 39. The sleeve 311 is slidably connected, and the flow velocity sensor 33 at one end of the fixed seat 31 records the flow velocity of water in different river sections, thereby providing more accurate water flow data for water quality testing. The plug 35 at one end of the sampling tube 34 prevents large debris in the river water from clogging the sampling tube 34. The piston 310 is pulled by the electric push rod 39. The piston 310 slides in the inner cavity of the sampling tube 34 and connects the sampling tube 34 with the discharge tube 36. One end of the sampling tube 34 is stably sealed by the sealing sleeve 311, so that the water sample can flow stably from the sampling tube 34 and the discharge tube 36 into the sampling tank 37.

[0027] Reference Figure 1 and Figure 2One end of the drain pipe 4 is fixedly connected to the end of the crossbar 21. A one-way valve 41 is fixedly connected to the end of the drain pipe 4. A through groove 23 is opened at the top of the crossbar 21. A bolt 24 is set in the middle of the connecting rod 2. The bolt 24 passes through both ends of the through groove 23. By loosening the bolt 24 in the through groove 23, the crossbar 21 can slide horizontally in the middle of the connecting rod 2. The horizontal movement of the crossbar 21 drives the traction rod 22 to move, thereby adjusting the water sample collection point. The air in the sampling tank 37 can be emptied by the drain pipe 4, so that water samples can flow into the sampling tank 37 stably. In specific implementation, the water sample in the sampling tank 37 can be led out through the one-way valve 41 and the drain pipe 4 via pipeline and self-priming pump for convenient water quality testing.

[0028] Working principle: In use, multiple synchronous sampling mechanisms 3 are set up in areas with different flow velocities in the river for synchronous sampling. The counterweight rod 1 and connecting rod 2 are used to stably support the crossbar 21, which in turn stably supports the traction rod 22 and the synchronous sampling mechanism 3 in the river water. The extension length of the crossbar 21 is fixed by the through groove 23 and bolt 24 to control the water sample collection point. The control circuit controls the electric push rod 39 in the waterproof sleeve 32 to synchronously pull the piston 310. The piston 310 slides in the sampling tube 34, connecting the sampling tube 34 and the discharge tube 36. The sealing sleeve 311 seals one end of the sampling tube 34. This allows water samples to flow from the sampling tube 34 into the sampling tank 37. The venting pipe 4 and the one-way valve 41 work together to vent the air in the sampling tank 37, allowing water samples to flow into the sampling tank 37 stably. The plug 35 at one end of the fixing seat 31 prevents large debris in the river water from clogging the sampling tube 34. The flow velocity sensor 33 at the other end of the fixing seat 31 records the water flow velocity during water sample collection, thus providing data on the water flow velocity for water sample detection. The water level sensor 38 detects the water level in the sampling tank 37. When the water level reaches a predetermined position, the electric actuator 39 pushes the piston 310 to close the sampling tube 34, thereby completing the synchronous collection of water samples.
