Description

Technical Field

[0001] This utility model relates to the field of water station sampler technology, and in particular to a flow-adaptive water sampling early warning device. Background Technology

[0002] Water quality monitoring stations are critical infrastructure for monitoring water quality. Their core function is to periodically collect water samples and analyze physicochemical and biological indicators to ensure that water quality meets relevant national or industry standards. Currently, the conventional operating method involves using a floating platform to transport sampling tanks to pre-set sampling points. The floating platform's drive mechanism then lowers the tanks to different water depths, and the samples collected at each depth are then distributed into individual collection bottles on the platform. This distribution process can be automated to improve sampling efficiency and safety. However, in practice, to ensure the representativeness and reliability of the water samples, the sampling tanks need to remain at specific depths for extended periods. During this time, the monitored water body may experience sudden increases in flow (such as heavy rain runoff or floods), causing the floating platform and sampling tanks to be subjected to strong water flow impacts, potentially leading to equipment damage or loss. Such problems not only increase the safety risks of water monitoring but also significantly increase the cost of equipment maintenance and replacement, negatively impacting the economic viability of the monitoring work. Utility Model Content

[0003] The main purpose of this invention is to provide a flow-adaptive water sampling and early warning device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The flow-adaptive water sampling early warning device includes a sampling tank that can be placed into the water body to be monitored. A sensor assembly is installed on one side wall of the sampling tank, and a guide mechanism opposite to the sensor assembly is installed on the other side wall of the sampling tank.

[0006] The guiding mechanism includes a fixed frame that is fixed to the sampling tank. The fixed frame has a fixed rod and a central shaft at the top of the fixed frame. A floating rod is rotatably connected to the central shaft, and a fan-shaped waterproof cloth is connected between the fixed rod and the floating rod.

[0007] Furthermore, the top of the fixing frame is also provided with a fixing lug, and the two ends of the central shaft are respectively connected to the fixing lug and the fixing rod;

[0008] Several connecting arms located between the fixed rod and the floating rod are rotatably connected to the central shaft, and each connecting arm is connected to the fan-shaped waterproof cloth.

[0009] Furthermore, a shock-absorbing rubber block is installed on the side wall of the sampling tank, located at the top of the sensor assembly.

[0010] Furthermore, it also includes a connecting frame, on which a support frame is provided, and an electric winder is installed on the support frame, with a connecting rope wound on the electric winder;

[0011] A rotating component is installed at the top center of the sampling tank, and the rotating component is connected to the end of the connecting rope.

[0012] Furthermore, the connecting frame is also provided with a limiting frame located below the support frame, and the limiting frame is provided with a limiting guide ring for limiting the connecting rope.

[0013] Furthermore, the connecting frame is also equipped with an anti-collision rubber plate located below the limiting frame.

[0014] Furthermore, the bottom end of the sampling tank has a counterweight base, which is ring-shaped;

[0015] Solenoid valve tubes are installed at both the top and bottom of the sampling tank, with the solenoid valve tube at the bottom of the sampling tank located in the area surrounded by the counterweight base.

[0016] Compared with existing technologies, this invention has the following advantages: In this invention, through the guiding mechanism, when the sampling tank is placed inside the water body, the floating rod rotates relative to the fixed rod to open the fan-shaped waterproof cloth. When the monitored water flow suddenly increases, the water flow impacts the fan-shaped waterproof cloth, causing the sampling tank to rotate adaptively. Thus, the sensor assembly located on the other side of the guiding mechanism can face the water flow, allowing the sensor assembly to collect more accurate data on flow velocity, flow rate, and other indicators. When the sensor assembly detects an abnormal flow, it can alert back-end personnel to adjust the sampling strategy in a timely manner. This not only effectively reduces the wear and tear on the water monitoring device in sudden situations but also improves the safety and economy of the monitoring process.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-8 As shown, the adaptive water sampling early warning device includes a sampling tank 5 that can be placed into the water body to be monitored. A sensor assembly 7 is installed on one side wall of the sampling tank 5, and a guide mechanism 8 opposite to the sensor assembly 7 is installed on the other side wall of the sampling tank 5.

[0026] The guiding mechanism 8 includes a fixed frame 86 fixed on the sampling tank 5. The fixed frame 86 has a fixed rod 81. The top of the fixed frame 86 is also provided with a central shaft 83. A floating rod 85 is rotatably connected to the central shaft 83. A fan-shaped waterproof cloth 84 is connected between the fixed rod 81 and the floating rod 85.

[0027] In this embodiment, sensor component 7 is used to collect indicators such as flow velocity and flow rate of the water body to be monitored in real time. Existing technologies can be used for sensor component 7.

[0028] In application, the sampling tank 5 is placed at a specific depth in the water. Under buoyancy, the floating rod 85 rotates upward relative to the fixed rod 81 to open the fan-shaped waterproof cloth 84. When the monitored water flow suddenly increases, the water flow impacts the fan-shaped waterproof cloth 84, causing the sampling tank 5 to rotate adaptively. In this way, the sensor assembly 7, located on the other side of the guide mechanism 8, can face the water flow, allowing the sensor assembly 7 to collect more accurate data on flow velocity, flow rate, and other indicators. When the sensor assembly 7 detects an abnormal flow, it sends a signal to the backend via the network module to remind backend personnel to adjust the sampling strategy in a timely manner. This effectively reduces the wear and tear on the water monitoring device in case of emergencies, thereby improving safety and economy.

[0029] As can be seen, the fan-shaped waterproof cloth 84 in the guide mechanism 8 can automatically adjust the circumferential angle of the sampling tank 5 according to the direction of water flow, ensuring that the sensor assembly 7 is always in the optimal sampling position. In addition, the float rod 85 should be made of a hollow, lightweight material, which provides better buoyancy.

[0030] When the sampling tank 5 is detached from the water body to be monitored, the float rod 85 can be rotated to retract the fan-shaped waterproof cloth 84 to the fixed frame 86. To improve the retraction effect of the fan-shaped waterproof cloth 84, fold lines 88 can be made on the fan-shaped waterproof cloth 84 in advance, such as... Figure 1 As shown. The fan-shaped waterproof fabric 84 can fill the area between the floating rod 85 and the fixing frame 86.

[0031] It is worth noting that the sampling tank 5 is used to collect water samples. The sampling tank 5 may include a tank for holding the sample. The tank should also be equipped with a power module that can control the function of the sensor component 7 and a sensor control motherboard that can transmit data to control the sensor component 7. To facilitate switching the sensor component 7 on and off, a network module may also be provided on the sensor control motherboard so that the back-end personnel can remotely control the sensor control motherboard.

[0032] Preferably, the top end of the fixing frame 86 is further provided with a fixing ear 87, and the two ends of the central shaft 83 are respectively connected to the fixing ear 87 and the fixing rod 81;

[0033] Several connecting arms 82 located between the fixed rod 81 and the floating rod 85 are rotatably connected to the central shaft 83, and each connecting arm 82 is connected to the fan-shaped waterproof cloth 84.

[0034] In this embodiment, as Figure 2 As shown, the fixing lug 87 can be configured to be the same length as the fixing rod 81, so that the connecting arm 82 and the floating rod 85 can be stored in the area between the fixing rod 81 and the fixing lug 87 when not placed in the water.

[0035] In application, the connecting arm 82 can support the fan-shaped waterproof cloth 84 to increase its resistance to water flow scouring, thereby making it easier to adjust the angle of the sampling tank 5 according to the flow direction.

[0036] To facilitate folding of the waterproof fan-shaped fabric 84, the waterproof fan-shaped fabric 84 can partially fill the area between the floating rod 85 and the fixing frame 86, such as... Figure 2 As shown.

[0037] Preferably, a shock-absorbing rubber block 6 is installed on the side wall of the sampling tank 5, located at the top of the sensor assembly 7. The shock-absorbing rubber block 6 can prevent the sensor assembly 7 from being damaged by collisions and extend its service life.

[0038] Preferably, it also includes a connecting frame 1, on which a support frame 14 is provided, and an electric winder 15 is installed on the support frame 14, with a connecting rope 11 wound on the electric winder 15.

[0039] A rotating component 16 is installed at the top center of the sampling tank 5, and the rotating component 16 is connected to the end of the connecting rope 11.

[0040] In this embodiment, the electric winding device 15 acts as a drive structure, controlling the number of turns of the connecting rope 11 and thus the depth at which the sampling tank 5 is immersed in the water. The rotating component 16 facilitates the rotation of the sampling tank 5 relative to the connecting rope 11 to adapt to the flow direction of the water.

[0041] The connecting frame 1 can be fixed on the rotation drive device on the floating vessel. The connecting frame 1 can be rotated as a whole by the rotation drive device to carry out sampling and water sample dispensing. The specific operation method is not discussed in this embodiment and will not be described here.

[0042] To achieve the fixing function between the connecting frame 1 and the rotation drive device, the connecting frame 1 can be designed as a hook, with a threaded rod 2 passing through the hook. To facilitate the rotation of the threaded rod 2, a knob 3 can also be installed at the end of the threaded rod 2. To prevent the connecting frame 1 from colliding during rotation, the bottom end of the connecting frame 1 can be set as an arc-shaped surface 4.

[0043] Preferably, the connecting frame 1 is further provided with a limiting frame located below the support frame 14, and the limiting frame is provided with a limiting guide ring 13 for limiting the connecting rope 11.

[0044] In this embodiment, the limiting guide ring 13 can limit the movement of the connecting rope 11, prevent the connecting rope 11 from getting tangled and deviating, and thus improve the stability of the sampling tank 5 moving up and down.

[0045] Preferably, the connecting frame 1 is further provided with a collision-resistant rubber plate 12 located below the limiting frame. In this embodiment, the collision-resistant rubber plate 12 can prevent accidental collisions from occurring during the up-and-down movement of the collection tank 5.

[0046] Preferably, the bottom end of the sampling tank 5 has a counterweight base 10, and the counterweight base 10 is annular;

[0047] Solenoid valve tubes 9 are installed at both the top and bottom of the sampling tank 5. The solenoid valve tube 9 located at the bottom of the sampling tank 5 is located in the area surrounded by the counterweight base 10.

[0048] In this embodiment, the coordinated action of the solenoid valve tubes 9 at the top and bottom enables the sampling tank 5 to perform both water intake and water dispensing. The counterweight base 10 ensures that the sampling tank 5 has sufficient mass to sink to a specific depth and also helps the sampling tank 5 maintain vertical stability in the water.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
