Description

Technical Field

[0001] This utility model relates to the field of environmental sampler technology, and in particular to a lifting device for an electric reservoir environmental sampler. Background Technology

[0002] As is well known, a reservoir environmental sampler is a specialized device used to collect environmental samples from reservoirs. It is primarily used for sampling and monitoring water quality, sediment, and organisms within the reservoir. Through various sampling devices, such as water samplers, sediment samplers, and biological nets, it can collect samples from different depths and locations within the reservoir. This allows for the analysis and evaluation of water quality, nutrient content, pollutant distribution, sediment characteristics, and the types and quantities of aquatic organisms, providing a scientific basis for reservoir environmental protection, water resource management, and ecological restoration. The lifting device is a crucial component of the reservoir environmental sampler. It precisely controls the vertical position of the sampler within the reservoir according to sampling requirements, accurately lowering the sampler to sampling points at different depths.

[0003] However, the lifting device of traditional electric reservoir environmental samplers is usually lifted manually. Manual lifting mainly relies on the experience and feel of the sampler to control the sampling depth, which is difficult to control precisely. Different samplers may have different strengths and feel, resulting in inconsistent sampling depths, which affects the accuracy and comparability of the sampling data. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting device for an electric reservoir environmental sampler. When in use, the lifting device activates a servo motor, which drives the active transmission chain in conjunction with auxiliary transmission chains one and two, simultaneously rotating the rope winding roller and screw. This ensures the rope is evenly wound around the central roller while lifting the sampler, automatically lifting it. Furthermore, a metering sensor, through the pull of the rope, drives the measuring pressure roller to rotate. The measuring pressure roller transmits a signal to the sensor via the central shaft. The sensor displays the data on the PLC control panel to measure the length. Two auxiliary wheels are responsible for clamping and guiding, ensuring the rope does not slip or deviate during pulling, thus guaranteeing accurate automatic meter counting.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A lifting device for an electric reservoir environmental sampler includes a support frame, a telescopic frame slidably connected to the outer wall of the rear end of the support frame, an auxiliary frame slidably connected to one side of the outer wall of the support frame, a main unit fixedly connected to the middle of the upper surface of the support frame, a mounting frame fixedly connected to the front end of the outer wall of the main unit, a clutch provided on one side of the inner wall of the mounting frame, a rope winding roller rotatably connected to the middle of the inner wall of the mounting frame, a screw rotatably connected to the front end of the inner wall of the mounting frame, and a threaded sleeve threadedly connected to the outer wall of the screw.

[0007] The lower end of the threaded sleeve is fixedly connected to a mounting frame. Rollers are rotatably connected to the upper and lower parts of the inner wall of the mounting frame. A rotating rod is rotatably connected to the front end of the outer wall of the mounting frame. A limit roller is rotatably connected to the lower end of the rotating rod. Limit springs are fixedly connected to both sides of the outer wall of the rotating rod. The rear end of the limit spring is fixedly connected to both sides of the outer wall of the mounting frame.

[0008] Compared with the existing lifting devices of electric reservoir environmental samplers, the lifting device of this electric reservoir environmental sampler uses a Y-shaped fixed bracket, two sets of telescopic brackets, and a vertical hook plate at the edge to hook onto the ship's side. This allows it to be used for different widths and angles of different ships. The telescopic part is equipped with fastening screws to lock the telescopic rod after adjusting the length, making it highly practical.

[0009] Furthermore, the upper surfaces of the bracket, telescopic frame, and auxiliary frame are all provided with multiple screw holes, and the screw holes are connected by fastening bolts.

[0010] The above technical solution allows for easy telescopic locking of the telescopic frame and auxiliary frame by using fastening bolts and matching screw holes.

[0011] Furthermore, vertical hook plates are fixedly connected to the edges of the lower surfaces of the bracket, telescopic frame, and auxiliary frame;

[0012] The above technical solution facilitates the securing of vessels using vertical hook plates.

[0013] Furthermore, a mounting plate is fixedly connected to the lower end of the outer wall of one side of the host, and a servo motor is fixedly connected to the upper end of the mounting plate. The output end of the servo motor is connected to the other side of the outer wall of the clutch by an active transmission chain.

[0014] The above technical solution allows the servo motor to easily drive the active transmission chain to rotate.

[0015] Furthermore, one side of the outer wall of the clutch is connected to one side of the outer wall of the rope winding roller by an auxiliary transmission chain one, and the other side of the outer wall of the rope winding roller and the screw is connected by an auxiliary transmission chain two.

[0016] The above technical solution facilitates the rotation of the rope winding roller and the screw by means of auxiliary transmission chain one and auxiliary transmission chain two.

[0017] Furthermore, a meter-counting sensor is provided on one side of the outer wall of the rope winding roller;

[0018] The above technical solution facilitates the measurement of lifting length using a meter-counting sensor.

[0019] Furthermore, a guide rod is fixedly connected to the inner wall of the mounting bracket near the rear end of the screw, and the guide rod passes through the threaded sleeve;

[0020] The above technical solution allows the guide rod to facilitate the lateral movement of the threaded sleeve by limiting its movement.

[0021] Furthermore, a PLC control panel is provided on the upper part of the outer wall of the rear end of the host, and the PLC control panel is electrically connected to the servo motor and the meter sensor respectively.

[0022] The above technical solution allows for easy control of the servo motor and meter sensor via a PLC control panel, facilitating their switching and data display.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a lifting device for an electric reservoir environmental sampler. Compared with existing lifting devices for electric reservoir environmental samplers, this lifting device, when in use, drives a servo motor to drive the active transmission chain, which in turn drives the auxiliary transmission chain one and the auxiliary transmission chain two to rotate the rope winding roller and the screw. This allows the rope to be evenly wound around the central roller while lifting the sampler, enabling automatic lifting of the sampler. In addition, the metering sensor, through the pull of the rope, drives the measuring pressure roller to rotate. The measuring pressure roller transmits the signal to the sensor through the central shaft. The sensor displays the data through the PLC control panel to measure the length. Two auxiliary rollers are responsible for pressing and guiding, ensuring that the rope does not slip or deviate when pulled, thus ensuring the accuracy of automatic meter counting.

The lifting device for an electric reservoir environmental sampler proposed in this utility model, compared with the existing lifting devices for electric reservoir environmental samplers, uses a Y-shaped fixed bracket, two sets of telescopic brackets, and a vertical hook plate at the edge to hook onto the ship's side. This allows it to be used for different widths and angles of different vessels. Fastening screws are provided at the telescopic part to lock the telescopic rod after the length is adjusted, resulting in higher practical performance. Attached Figure Description
