Description

Technical Field

[0001] This application relates to the field of environmental monitoring technology, and in particular to a sampling device for monitoring the ecological environment of aquatic bodies. Background Technology

[0002] Environmental monitoring refers to the continuous or intermittent monitoring, analysis, and evaluation of the quality status of various elements in the natural environment through scientific methods. Its core purpose is to understand the patterns of environmental quality changes, identify pollution sources, and provide early warnings of environmental risks, thus offering data support for environmental protection decision-making, pollution control, and ecological restoration. In the ecological and environmental protection system, aquatic ecological environment monitoring is a crucial link. It involves sampling and analyzing water quality indicators, biological communities, and hydrological parameters (such as flow rate and water depth) in surface water, groundwater, and seawater to reflect the health status of aquatic ecosystems. This is an important foundation for ensuring water resource security and maintaining aquatic ecological balance.

[0003] Currently, manual operation remains a widely used method in aquatic ecological environment monitoring sampling. This mainly involves directly scooping surface water samples with simple tools such as handheld sampling bottles and buckets, or using long-handled sampling spoons and sampling tubes to collect shallow underwater samples. This traditional sampling mode has obvious limitations. On the one hand, it is difficult to obtain samples from different water depths, such as mid-deep waters. On the other hand, operators need to work close to the shore or even wade in the water, which can easily lead to slips, falls, and other safety accidents, threatening the personal safety of monitoring personnel. It also limits the sampling work in some dangerous areas. Therefore, to solve the above problems, we provide a sampling device for aquatic ecological environment monitoring. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for monitoring the aquatic ecological environment, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: A sampling device for monitoring the aquatic ecological environment includes a support base. Two bearing rings are fixedly embedded in the inner wall of the support base. The inner rings of the two bearing rings are fixedly connected to a rotating shaft. A folding support plate is fixedly connected to the outer surface of the rotating shaft. A driving assembly is fixedly connected to the upper surface of the folding support plate. A scale rope is provided below the driving assembly. A strip-shaped through hole is opened on the bottom surface of the folding support plate. The top end of the scale rope is located inside the hole. A liquid inlet assembly is provided at the bottom end of the scale rope. The liquid inlet assembly includes a housing. A sampling tube is provided outside the housing. One end of the sampling tube passes through the housing and extends into the interior of a sampling vessel. A solenoid valve is fixedly connected to the outer surface of the sampling tube. A sampling vessel is provided below the liquid inlet assembly.

[0006] Preferably, the drive assembly includes a support cover fixedly mounted on the upper surface of the folding support plate, a reduction motor fixedly mounted on one side of the support cover, a drive rod fixedly mounted on the output end of the reduction motor, one end of the scale rope fixedly connected to the outer surface of the drive rod, and two bearing rings fixedly embedded in the inner wall of the support cover, with the inner rings of the two bearing rings fixedly connected to the outer surfaces of both ends of the drive rod.

[0007] Preferably, a threaded retaining ring is fixedly connected to the bottom surface of the housing, the inner ring of the threaded retaining ring is threadedly connected to the outer surface of the top of the sampling vessel, and a plurality of reinforcing plates are fixedly connected to the upper surface of the housing, with one side of the reinforcing plates fixedly connected to the outer surface of the graduated rope.

[0008] Preferably, the inner wall of the support base is hinged with a reinforcing plate by a damping pin, and the bottom surface of the folding plate is provided with a positioning groove, with one end of the reinforcing plate extending into the interior of the positioning groove.

[0009] Preferably, a support base is fixedly connected to the bottom surface of the support base, and a circular placement groove adapted to the thread on the bottom surface of the sampling vessel is provided on the upper surface of the support base. A sealing plug plate adapted to the inner thread on the top of the sampling vessel is provided above the circular placement groove.

[0010] Preferably, a controller and a portable handle are fixedly installed on one side of the support base, the portable handle is located below the controller, and a power supply is fixedly installed on the inner wall of the housing.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: I. This sampling device for water body ecological environment monitoring uses a reduction motor to drive a drive rod to release a graduated rope. Staff can control the descent depth of the liquid inlet component based on the clear graduations on the rope, allowing for the acquisition of representative water samples at different depths. This solves the problem that traditional sampling methods cannot cover diverse depth requirements. Furthermore, the combination of the sampling tube and the solenoid valve enables control of the sampling process, preventing water flow disturbances from affecting the samples. After sampling, the sampling container is detachable via a threaded fixing ring, and combined with a sealing plug and a circular placement groove, it achieves sealed preservation and temporary storage of the sample, ensuring sample integrity. This will provide diverse water sample data for water body ecological environment monitoring.

[0012] Second, the sampling device for water ecological environment monitoring, through the cooperation of the bearing ring and the rotating shaft, allows the folding support plate to be flexibly unfolded. By reinforcing the support plate and fixing it with the positioning groove, the sampling radius can be extended. This will allow operators to complete sampling operations in offshore and deep water areas from a safe area on the shore, avoiding safety accidents such as slipping and falling into the water caused by slippery banks and rapid water flow. At the same time, it breaks the limitation of sampling in dangerous areas and ensures the personal safety of monitoring personnel. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 This utility model provides a technical solution for a sampling device for monitoring the aquatic ecological environment: A sampling device for monitoring the aquatic ecological environment includes a support base 1. Two bearing rings 8 are fixedly embedded in the inner wall of the support base 1. A rotating shaft 7 is fixedly connected to the inner rings of the two bearing rings 8. A folding support plate 2 is fixedly connected to the outer surface of the rotating shaft 7. A drive assembly 3 is fixedly connected to the upper surface of the folding support plate 2. A graduated rope 4 with graduated lines is located below the drive assembly 3. A strip-shaped through hole 9 is opened on the bottom surface of the folding support plate 2, and the top end of the graduated rope 4 is located inside it. A liquid inlet assembly 5 is located at the bottom end of the graduated rope 4. The liquid inlet assembly 5 includes a housing 51. A sampling tube 54 is located outside the housing 51. One end of the sampling tube 54 passes through the housing 51 and extends into the interior of a sampling vessel 6. A solenoid valve 53 is fixedly connected to the outer surface of the sampling tube 54. A controller 10 sends an electrical signal to the solenoid valve 53 through a preset program or manual command. Power supply 52 provides working voltage to solenoid valve 53. When the electrical signal is triggered, the coil inside solenoid valve 53 is energized to generate a magnetic field, which drives the valve core to move and open the passage. Water flows into sampling vessel 6 through sampling tube 54. When the signal is interrupted, the coil is de-energized, the valve core resets and closes the passage, realizing the start and stop control of the sampling process. Sampling vessel 6 is set below liquid inlet assembly 5. Specifically, bearing ring 8 provides stable support for rotating shaft 7. Rotating shaft 7 can drive folding support plate 2 to rotate flexibly, realizing the extension and adjustment of the sampling area. Drive assembly 3 is fixed above folding support plate 2 and connected to liquid inlet assembly 5 through scale rope 4. Strip-shaped through hole 9 provides a channel for the opening and closing of scale rope 4. Housing 51 of liquid inlet assembly 5 provides a mounting carrier for sampling tube 54 and solenoid valve 53. Sampling tube 54 is responsible for water introduction, solenoid valve 53 controls the sampling on and off, and sampling vessel 6 realizes the storage and collection of water samples.

[0018] In this embodiment, the drive assembly 3 includes a support cover 31 fixedly mounted on the upper surface of the folding support plate 2. A reduction motor 32 is fixedly mounted on one side of the support cover 31. A drive rod 33 is fixedly mounted on the output end of the reduction motor 32. One end of the scale rope 4 is fixedly connected to the outer surface of the drive rod 33. Two bearing rings 34 are fixedly embedded in the inner wall of the support cover 31. The inner rings of the two bearing rings 34 are fixedly connected to the outer surfaces of both ends of the drive rod 33. Specifically, the support cover 31 plays a protective and fixing role. The reduction motor 32 mounted on one side of it can provide power for sampling. The output end drives the drive rod 33 to rotate, realizing the winding and releasing of the scale rope 4. The bearing rings 34 on the inner wall of the support cover 31 reduce the frictional resistance when the drive rod 33 rotates, ensuring the smoothness of the driving process.

[0019] In this embodiment, a threaded retaining ring 56 is fixedly connected to the bottom surface of the housing 51. The inner ring of the threaded retaining ring 56 is threadedly connected to the outer surface of the top of the sampling vessel 6. A plurality of reinforcing plates 55 are fixedly connected to the upper surface of the housing 51, and one side of the reinforcing plate 55 is fixedly connected to the outer surface of the scale rope 4. A reinforcing support plate 11 is hinged to the inner wall of the support base 1 through a damping pin. A positioning groove 12 is opened on the bottom surface of the folding support plate 2, and one end of the reinforcing support plate 11 extends into the interior of the positioning groove 12. Specifically, the threaded retaining ring 56 enables the detachable connection of the sampling vessel 6, which facilitates sample removal and vessel replacement. The reinforcing plate 55 enhances the connection stability between the scale rope 4 and the housing 51, preventing it from falling off during sampling. The reinforcing support plate 11 on the inner wall of the support base 1 is hinged to the damping pin. After being inserted into the positioning groove 12 of the folding support plate 2, the unfolding angle of the folding support plate 2 can be fixed to ensure the structural stability during sampling.

[0020] In this embodiment, a support base 13 is fixedly connected to the bottom surface of the support base 1. A circular placement groove 14 adapted to the thread on the bottom surface of the sampling vessel 6 is opened on the upper surface of the support base 13. A sealing plug plate 15 adapted to the inner thread on the top of the sampling vessel 6 is provided above the circular placement groove 14. A controller 10 and a portable handle 16 are fixedly installed on one side of the support base 1. The portable handle 16 is located below the controller 10. A power supply 52 is fixedly installed on the inner wall of the housing 51. Specifically, the support base 13 on the bottom surface of the support base 1 ensures that the device is placed stably. The circular placement groove 14 can temporarily store the sampling vessel 6. The sealing plug plate 15 realizes the sealed preservation of the sample after sampling. The controller 10 is used to control the operation of the reduction motor 32 and the solenoid valve 53. The portable handle 16 facilitates the movement and transportation of the device. The power supply 52 in the housing 51 provides power support for the solenoid valve 53 and ensures the normal operation of each electrical component.

[0021] Working principle: When the sampling device for water ecological environment monitoring is used, the device is securely placed on the support base 13 on the bottom of the support seat 1. It can be flexibly moved to the target sampling point with the help of the portable handle 16. The operator drives the rotating shaft 7 through the bearing ring 8 to unfold the folding support plate 2 to a suitable angle. Then, the reinforced support plate 11, which is hinged by the damping pin, is inserted into the positioning groove 12 to achieve stable fixation of the folding support plate 2. The sampling area can be extended without approaching the dangerous shore. Then, the controller 10 starts the reduction motor 32 in the drive assembly 3. Its output end drives the drive rod 33 to rotate in the bearing ring 34, thereby releasing the scale rope 4 wrapped on the drive rod 33. The scale rope 4 drives the liquid inlet assembly 5 below to sink through the strip-shaped through hole 9. The operator can control the sampling depth according to the scale of the scale rope 4.

[0022] When the liquid inlet component 5 reaches the preset depth, the solenoid valve 53 is opened by the controller 10. The water enters the sampling vessel 6 through the sampling tube 54 to achieve sampling. After sampling, the solenoid valve 53 is closed again by the controller 10, and the deceleration motor 32 is started to reverse and retrieve the scale rope 4, lifting the liquid inlet component 5 and the sampling vessel 6 together to a safe area. The sampling vessel 6 is detachably connected to the housing 51 by the threaded fixing ring 56. After removal, the sealing plug plate 15 can be screwed into the top of the sampling vessel 6 for sealing and preservation, or it can be placed directly into the circular placement groove 14 of the support base 13 for temporary storage.
