[0007] The following are further optimizations of the above technical solution by this utility model: The height adjustment mechanism includes a winding assembly, a self-adaptive assembly, and a steering assembly arranged sequentially along the rope transmission path.

[0009] Further optimization: The self-adaptive component includes two sets of adjustment frames arranged symmetrically at the top and bottom. Each set of adjustment frames has a tensioning wheel that is rotatably installed on it.

[0016] The present invention adopts the above technical solution and has the following beneficial effects: 1. The present invention adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. The position adjustment drive mechanism drives the adjustment seat to adjust the horizontal displacement in the horizontal direction, and combined with the angle adjustment drive mechanism to drive the support frame to rotate. The two form a coordinated mechanism for position and angle adjustment, which enables the present invention to achieve automated sampling coverage of a large area and multiple directions of water area while the base is fixed in the same position. On the one hand, it replaces the manual hand operation of traditional sampling devices, which greatly reduces the workload of sampling personnel.

[0021] 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 protection scope of the present utility model.

[0022] like Figures 1-3 As shown in the figure, a water sampling device for water conservancy projects includes a base 1, a water sampler 2, an angle adjustment device, a horizontal adjustment device, and a height adjustment device.

[0023] In this embodiment, the water sampler 2 can preferably be a commercially available automatic sampler with mature technology and strong adaptability to simplify the equipment integration process and ensure the stability of sampling performance, such as the HX-B type multi-field water quality automatic sampler produced by Haiyang Qiheng Environmental Protection Technology Co., Ltd.

[0024] Preferably, the angle adjustment device is used to adjust the water intake angle of the water dispenser 2. The angle adjustment device includes a support frame 3 rotatably mounted on the base 1, and the support frame 3 is connected to an angle adjustment drive mechanism for adjusting the water intake angle.

[0025] In this embodiment, the support frame 3 includes a vertically arranged column and a horizontally extended support arm. The two are integrally fixedly connected to form an L-shaped rigid support structure to ensure the overall load-bearing strength of the sampling equipment so that it meets the requirements of subsequent working conditions.

[0026] Furthermore, the lower end of the column is rotatably mounted on the base 1 via a rotating connection structure. This rotating connection structure can be a bearing-fit structure or a hinge connection structure. Its component composition, installation relationship, and assembly principle are all existing technologies and will not be described in detail here.

[0027] Preferably, the horizontal adjustment device is used to adjust the horizontal water intake position of the water dispenser 2. The horizontal adjustment device includes an adjustment seat 4 that is slidably installed on the upper end of the support frame 3 in the horizontal direction. The adjustment seat 4 is connected to a position adjustment drive mechanism for driving the adjustment seat 4 to make horizontal displacement.

[0028] Preferably, the height adjustment device is used to adjust the vertical position of the water dispenser 2. The height adjustment device includes a height adjustment mechanism disposed on the support frame 3, and the water dispenser 2 is connected to the height adjustment mechanism via a rope 5.

[0029] Preferably, the height adjustment mechanism includes a winding assembly, a self-adaptive assembly, and a steering assembly arranged sequentially along the transmission path of the rope 5. The end of the rope 5 away from the water dispenser 2 passes through the steering assembly and the self-adaptive assembly in sequence and then winds around the winding assembly.

[0030] In this embodiment, the core function of the self-adaptive component is to adjust the tension of the rope 5 in real time and automatically during the winding and unwinding process. This not only solves the problems of excessive tension and loose winding, but also works in coordination with the winding component and the steering component for transmission.

[0031] On the one hand, it has a tension buffering effect on the twisted rope 5, reducing the impact of sudden changes in tension on the winding servo motor 8 during the winding and unwinding process, and extending the service life of the winding servo motor 8; on the other hand, it can ensure that the twisted rope 5 is always in a taut state, improving the safety of the transmission, thereby ensuring a strict match between the speed below the water sampler 2 and the rotation speed of the winding roller 7, and further improving the sampling accuracy of the sampling work.

[0032] Preferably, the winding assembly includes a U-shaped frame 6 and a winding roller 7 horizontally rotatably mounted inside the U-shaped frame 6. The twisted rope 5 is regularly wound around the outer circumferential surface of the winding roller 7, and the winding roller 7 is drivenly connected to a winding servo motor 8.

[0033] In this embodiment, the U-shaped frame 6 is firmly installed on the lower end of the support frame 3 on the preset mounting plane, and the housing of the winding servo motor 8 is fixed on the U-shaped frame 6.

[0034] Therefore, when the support frame 3 rotates circumferentially, the U-shaped frame 6 can ensure that the winding assembly always maintains the preset winding angle and height, avoiding situations such as the rope 5 getting tangled or falling off during the winding process due to asynchronous movement.

[0035] Preferably, the self-adaptive component includes two sets of adjustment frames 9 arranged symmetrically at the top and bottom, and a tensioning wheel 10 is rotatably installed on each set of adjustment frames 9. The two ends of the adjustment frame 9 are slidably assembled to the inner side of the U-shaped frame 6 in the horizontal direction.

[0036] In this embodiment, an elongated groove structure is provided on the outer side of both ends of the adjustment frame 9, corresponding to the side wall of the matching U-shaped frame 6. The elongated groove extends along the axial direction of the winding roller 7.

[0037] At the same time, limit pins are installed at corresponding positions at both ends of the adjustment frame 9, and each fiber extends outward in the horizontal direction and slides into the corresponding long waist groove on the U-shaped frame 6 to form a sliding fit pair.

[0038] Therefore, on the one hand, it achieves directional constraint and stable guidance of the sliding trajectory of the adjustment frame 9, ensuring that the axial direction of the tension wheel 10 installed on the adjustment frame 9 is always perpendicular to the axis of the winding roller 7, avoiding the situation where the rope 5 is not smoothly driven or misaligned due to the deviation of the tension wheel 10.

[0039] On the other hand, it enables the adjusting frame 9 to maintain smooth sliding when subjected to the tension of the rope 5 or the buffering force of the damper 11, avoiding tilting or jamming, thus ensuring the continuity and stability of the clamping and tension adjustment action of the tension wheel 10 on the rope 5, and providing a reliable guarantee for the tension balance during the winding and unwinding process of the rope 5.

[0040] Preferably, dampers 11 are installed at both ends of the adjustment frame 9 and the U-shaped frame 6.

[0041] In this embodiment, the damper 11 can be a commercially available pneumatic damper, such as the LIFT-O-MAT type combined gas spring manufactured by Steyrus.

[0042] The moment the water extractor 2 is lowered to the water surface, the buoyancy of the water immediately acts on the water extractor 2, causing a sudden decrease in the tension on the winch 5, which in turn leads to a mismatch between the descent speed of the water extractor 2 and the rotation speed of the take-up roller 7. To address this issue, this invention installs a damper 11 between the adjusting frame 9 and the U-shaped frame 6, and maintains the damper 11 at a preset tension, causing the tensioning wheel 10 to continuously apply a stable tension force to the winch 5 under the action of the damper 11.

[0043] Specifically, even if the rope 5 becomes slightly slack, the tensioning wheel 10 can tighten the rope 5 in time under the drive of the damper 11, ensuring that the rope 5 is always in a taut state. At the same time, the clamping contact point between the tensioning wheel 10 and the rope 5 is always on the same plane, effectively avoiding the problem of the rope 5 shifting or deviating from the preset trajectory due to the offset of the tensioning wheel 10.

[0044] Similarly, during the winding process, when the water extractor 2 leaves the water surface, the buoyancy of the water disappears, and the tension on the winch 5 increases sharply due to the instantaneous loading of the weight of the water extractor 2, which can easily cause the water extractor 2 to tilt and tip over or cause the internal water sample to overflow. In this utility model, the upper and lower tensioning wheels 10 are simultaneously subjected to the radial thrust of the winch 5, pushing the adjusting frame 9 to slide horizontally away from the winch 5, while compressing the damper 11.

[0045] Therefore, by transforming the sudden instantaneous impact force into a slow linear tension, the shaking of the water dispenser 2 caused by the instantaneous impact force is avoided, as is the impact on the winding servo motor 8, thus extending the service life of this utility model.

[0046] Preferably, the axial direction of the tensioning wheel 10 is perpendicular to the axial direction of the take-up roller 7, and the rope 5 is clamped between the two tensioning wheels 10 and closely fitted to the side wall of the tensioning wheel 10.

[0047] Preferably, the steering assembly includes a first steering group and a second steering group. The first steering group includes at least one first steering wheel 12, and the first steering wheel 12 is rotatably mounted on the upper end of the support frame 3. The second steering group includes at least one pair of second steering wheels 13, and the second steering wheels 13 are rotatably mounted on the adjustment seat 4.

[0048] In this embodiment, the coordinated operation of the self-adaptive component and the steering component eliminates faults such as tangling, jamming, and breakage of the winch rope 5, thereby extending the service life of the winch rope 5.

[0049] Preferably, the angle adjustment drive mechanism includes a drive gear 14 and a driven gear 15 that are meshed together. The drive gear 14 is rotatably mounted inside the base 1 and is connected to an angle adjustment servo motor 16. The driven gear 15 is coaxially fixed to the lower end of the support frame 3.

[0050] In this embodiment, the angle adjustment drive mechanism outputs and transmits the power of the angle adjustment servo motor 16 through gear meshing transmission, thereby realizing the multi-angle rotation of the support frame 3, enabling the support frame 3 to achieve continuous rotation within the range of 0-180°, thus making this utility model applicable to different water conservancy projects (shore, center, shallow water, deep water area, etc.), with strong applicability.

[0051] Moreover, the base 1 can complete the collection of water samples from multiple directions and depths with a single fixation, thereby improving the efficiency of the sampling work.

[0052] Preferably, the position adjustment drive mechanism includes an electric slide rail 17 extending horizontally, the track of which is fixed on the support frame 3, and the adjustment seat 4 is fixedly installed on the slider of the electric slide rail 17.

[0053] In this embodiment, the electric slide rail 17 can be a commercially available electric guide rail structure, such as the MSA series all-steel ball bearing heavy-duty linear slide rail manufactured by Yintai Technology Co., Ltd.

[0054] Preferably, the base 1 integrates a battery 18 to provide independent power for the winding servo motor 8, the angle adjustment servo motor 16, and the electric slide rail 17.

[0055] In this embodiment, the battery 18 enables the present invention to operate without relying on an external power source, thus meeting the needs of surveying and sampling work for water conservancy projects that need to be built in the field.

[0056] Meanwhile, the battery 18 can also provide a stable DC power supply for the winding servo motor 8, the angle adjustment servo motor 16, and the electric slide rail 17.

[0057] Preferably, the support frame 3 is equipped with a control box 19, and the control systems of the winding servo motor 8, the angle adjustment servo motor 16, and the electric slide rail 17 are all electrically connected to the control box 19.

[0058] In this embodiment, the control box 19 can be a commercially available control device, whose structural components, working principle, connection and control method are all existing technologies and will not be described in detail here.

[0059] In summary, in order to address the shortcomings of existing water sampling equipment in water conservancy projects, this utility model provides a water sampling device for water conservancy projects that is multi-directionally adjustable, has a large sampling range, and offers high operational stability and safety.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
