Technical Field
[0001] This utility model relates to the field of water environment monitoring technology, specifically to a water environment monitoring sampling device. Background Technology
[0002] Water environment monitoring focuses on the aquatic environment, employing physical, chemical, and biological techniques to conduct qualitative, quantitative, and systematic comprehensive analysis of pollutants and their related components in order to explore and study the patterns of change in water quality. Water environment monitoring provides reliable basic data for water environment management and a scientific basis for evaluating the effectiveness of treatment measures. To ensure that monitoring data accurately reflects the current state of water quality and predicts the development trend of water pollution, it is often necessary to sample water bodies for precise testing of various data points.
[0003] Currently, when sampling water bodies, a long water pipe is often inserted into the water and then pumped out. However, because the water pipe is prone to floating, it is difficult to effectively reach the bottom when the water is deep. In addition, water of different depths can easily accumulate inside the water pipe, making it difficult to accurately collect water at the specified depth. This greatly affects the accuracy of subsequent test data and results in poor performance. Utility Model Content
[0004] The purpose of this invention is to provide a water environment monitoring and sampling device. By setting up an electric push rod, a connecting frame, a winding mechanism, and a water sampling mechanism, the connecting frame can drive the water sampling mechanism to move horizontally above the water surface. Then, the winding mechanism can release the connecting rope, which drives the sampling cylinder to descend along the guide wheel. Under the gravity of the sampling cylinder, the sampling cylinder can sink vertically in the water and quickly reach the specified depth. Then, multiple positioning columns simultaneously drive the stop block to rise inside the sampling cylinder, exposing the through hole, allowing water to quickly flow into the sampling cylinder. Then, the sampling cylinder is resealed, and finally, the sampling cylinder can be driven to rise again, thus effectively completing the water sampling at the specified depth. The sampling is accurate and stable, and the usage effect is good, thus solving the above-mentioned shortcomings in the technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water environment monitoring and sampling device, comprising:
[0006] A fixed frame is provided with an electric push rod at the top of the fixed frame. The output end of the electric push rod is connected to a connecting frame. A vertical frame is fixed to the top side of the connecting frame. A guide wheel is rotatably connected to the side wall of the vertical frame through a rotating shaft.
[0007] A connecting rope is wound around the guide wheel, and one end of the connecting rope is provided with a winding mechanism, while the other end of the connecting rope is connected to a water intake mechanism.
[0008] The water sampling mechanism includes a sampling cylinder with multiple through holes on the upper side wall and a movable stop block inside. The top of the sampling cylinder has a cavity. On the top side of the sampling cylinder, near the cavity, multiple threaded rods are arranged in a ring array via bearings. The bottom of each threaded rod is connected to a positioning post by a threaded connection, and the top of the threaded rod extends into the cavity and is equipped with a transmission component. A limiting component is provided between the positioning post and the sampling cylinder, and the bottom of the positioning post is fixedly connected to the stop block. The top of the sampling cylinder is equipped with a sealing cover, and the top of the sealing cover is connected to a connecting rope.
[0009] Preferably, the winding mechanism includes a support frame disposed on the bottom side of the connecting frame, a first motor is fixed to one end of the support frame, and a winding drum is rotatably connected to the inner side of the support frame via a rotating shaft. The output end of the first motor is connected to the winding drum, and the end of the connecting rope relative to the sampling cylinder is connected to the winding drum.
[0010] Preferably, the transmission assembly includes a geared disc rotatably connected to the middle of the cavity via a rotating shaft, the top ends of the plurality of threaded rods extending into the cavity and equipped with gears, the plurality of gears meshing with each other, and a second motor disposed inside the sealing cover, the output end of the second motor extending into the cavity and connected to the geared disc.

[0013] Preferably, one end of the fixing frame is provided with a handrail, and the bottom side of the fixing frame is provided with casters.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] By incorporating an electric push rod, connecting frame, winding mechanism, and water intake mechanism, the connecting frame can move the water intake mechanism horizontally above the water surface. The winding mechanism then releases the connecting rope, which, along the guide wheel, lowers the sampling cylinder. Under the weight of the sampling cylinder, it sinks vertically into the water and quickly reaches the designated depth. Multiple positioning columns then simultaneously raise the stop block inside the sampling cylinder, exposing the through-hole, allowing water to rapidly flow into the cylinder. The sampling cylinder is then resealed, and finally, it rises back up, effectively completing the water collection at the designated depth. The sampling is precise and stable, resulting in good performance. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model provides, for example Figures 1-4 The water environment monitoring and sampling device shown includes:
[0025] A fixed frame 1 is provided with an electric push rod 4 on its top. The output end of the electric push rod 4 is connected to a connecting frame 5. A vertical frame 9 is fixed to the top side of the connecting frame 5. A guide wheel 10 is rotatably connected to the side wall of the vertical frame 9 through a rotating shaft.
[0026] A connecting rope 11 is wound around the guide wheel 10, and one end of the connecting rope 11 is provided with a winding mechanism, and the other end of the connecting rope 11 is connected to a water intake mechanism.
[0027] The winding mechanism includes a support frame 6 located on the bottom side of the connecting frame 5. A first motor 8 is fixed to one end of the support frame 6, and a winding drum 7 is rotatably connected to the inner side of the support frame 6 via a rotating shaft. The output end of the first motor 8 is connected to the winding drum 7, and one end of the connecting rope 11 relative to the sampling cylinder 12 is connected to the winding drum 7.
[0028] The first motor 8 drives the winding drum 7 to rotate, which can wind up or release the connecting rope 11. Then the connecting rope 11 can slide along the guide wheel 10 and drive the sampling tube 12 to rise and fall. By controlling the number of rotations of the winding drum 7 by the controller, the winding and unwinding length of the connecting rope 11 can be controlled, thereby adjusting the depth of the sampling tube 12 in the water.
[0029] The water sampling mechanism includes a sampling cylinder 12. Multiple through holes 14 are provided on the upper side wall of the sampling cylinder 12, and a movable stop block 23 is provided inside the sampling cylinder 12. A cavity 16 is provided at the top of the sampling cylinder 12. Multiple threaded rods 19 are arranged in a ring array through bearings on the lower side of the top of the sampling cylinder 12 near the cavity 16. The bottom end of the threaded rod 19 is connected to a positioning post 20 by threaded engagement, and the top end of the threaded rod 19 extends into the cavity 16 and is provided with a transmission component. The bottom end of the positioning post 20 is fixedly connected to the stop block 23. A limiting component is provided between the positioning post 20 and the sampling cylinder 12. A sealing cover 13 is provided at the top of the sampling cylinder 12, and the top end of the sealing cover 13 is connected to a connecting rope 11.
[0030] The transmission assembly includes a gear disk 17 rotatably connected to the middle of the cavity 16 via a rotating shaft, the top ends of multiple threaded rods 19 extending into the cavity 16 and equipped with gears 18, multiple gears 18 meshing with each other, and a second motor 15 disposed inside the sealing cover 13, the output end of the second motor 15 extending into the cavity 16 and connected to the gear disk 17.
[0031] In use, the connecting frame 5 can be moved laterally by the electric push rod 4, so that the connecting frame 5 can move the water sampling mechanism horizontally above the water surface. After moving to the designated water surface position, the movement stops. Then, the winding mechanism can be started, and the winding drum 7 can be driven to rotate by the first motor 8. The winding drum 7 can be rotated to release the connecting rope 11. Then the connecting rope 11 can slide along the guide wheel 10 and drive the sampling drum 12 to descend. By controlling the number of rotations of the winding drum 7 by the controller, the depth to which the connecting rope 11 drives the sampling drum 12 into the water can be controlled. Under the action of gravity, the sampling drum 12 can sink vertically in the water, so as to quickly reach the designated depth position.
[0032] The water collection mechanism can then be activated, driving the gear disc 17 to rotate via the second motor 15. The gear disc 17 can drive multiple sets of gears 18 to rotate synchronously, and then the gears 18 can drive the threaded rod 19 to rotate. With the cooperation of the limiting component, the threaded rod 19 can drive the positioning column 20 to move upward in a straight line. Then, multiple positioning columns 20 can simultaneously drive the stop block 23 to rise inside the sampling tube 12, thereby exposing the through hole 14, allowing water to quickly flow into the sampling tube 12. Afterward, the stop block 23 is controlled to move downward again and block the through hole 14 to reseal the sampling tube 12. Then, the water collection mechanism can be driven to rise again via the winding mechanism, thus effectively completing the water collection at the specified depth. The sampling is accurate and stable, and the effect is good.
[0033] A lifting ring is provided at the top of the sealing cover 13, and one end of the connecting rope 11 is fixedly connected to the sealing cover 13 through the lifting ring. Based on this, by providing the lifting ring, the connecting rope 11 can be tied tightly to the lifting ring so as to connect the sampling cylinder 12 to the connecting rope 11, and vice versa, it can be quickly untied for convenient maintenance and use.
[0034] The limiting assembly includes a limiting rod 21 disposed on the top side wall of the positioning column 20, and multiple limiting grooves 22 matching the limiting rod 21 are provided on the inner side of the sampling cylinder 12 near the through hole 14. Based on this, by setting the limiting rod 21 and the limiting grooves 22, the positioning column 20 can drive the limiting rod 21 to slide along the limiting grooves 22, thereby supporting and limiting the positioning column 20, and thus greatly ensuring the stability of the lifting and moving of the positioning column 20.
[0035] A handrail 2 is provided at one end of the fixed frame 1, and a caster wheel 3 is provided on the bottom side of the fixed frame 1. Based on this, the handrail 2 and the caster wheel 3 facilitate the pushing and pulling of the moving device.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
