Description

Technical Field

[0001] The invention belongs to the technical field of lifting devices, and in particular relates to an automatic profile lifting device. Background Art

[0002] Collect water samples from polluted water bodies and analyze and measure them to obtain basic data on water pollution. Water samples for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, location, time, and frequency are all determined based on the characteristics of the water body and the purpose of analysis.

[0003] When monitoring the pollution of river water, it is generally necessary to sample the river water. The existing sampling method is to sample the river water through a sampling bottle. In patent 202220021270.0, a river water sampling device includes: a vertical pole, a clamping mechanism and a sampling bottle. The vertical pole is provided with a limit hole from top to bottom. The clamping mechanism includes: a clamping frame and a fastening nut. The clamping frame is provided with a latch, and the latch enters the limit hole. The pin body of the latch is provided with an external thread, and the fastening nut is provided with an internal thread. The internal thread of the fastening nut is connected with the external thread of the latch. The fastening nut fixes the clamping frame at the position of the limit hole. The clamping frame clamps the sampling bottle. The bottle mouth of the sampling bottle is provided with an electric control valve, and the electric control valve is connected to the external control switch through a wire. By setting a vertical pole and providing a limit hole on the vertical pole. By limiting the clamping mechanism to the limit hole, the clamping mechanism can be connected to different positions of the vertical pole. Finally, by arranging a sampling bottle on the clamping mechanism and controlling the bottle mouth of the sampling bottle, sampling of water bodies at different depths of the river can be achieved through the sampling bottle, thereby improving the sampling efficiency.

[0004] However, the above method is to hold the sampling bottle at different heights of the pole for sampling, and the sampling height is limited, and deep sampling is not possible. When deep sampling is required, a professional lifting mechanism is required to complete it, so that the detection is more accurate and convenient.

[0005] However, the traditional lifting mechanism using oil cylinder and hydraulic pump, reference patent 201610238092.6, is expensive. In addition, the chain will be retracted and released during the lifting process. If the chain is not reeled along the same plane during the reeling process, the chain will be misaligned, resulting in the chain not being reeled up, affecting the unwinding process. In addition, during the reeling process, the chain will contact the corners of the mechanism and get stuck, resulting in failure of reeling and affecting work efficiency. Summary of the invention

The water pump transition plate 411 is also provided with a sensor junction box 44, an oxygen concentration sensor 46, a water pump mounting plate 418, a water pump junction box 49, a liquid level transmitter 410, and a travel switch top block 415. A DC water pump 47 is installed on the water pump mounting plate 418. The above connections are all made by conventional bolts or screws.

[0063] It also includes two wires and a water pipe, one end of the two wires is connected to the rotor 1111 of the conductive slip ring 111, and then the wires pass through the stator 1110, and the other end passes through a plurality of threading plates 23 along the chain 2 in sequence and is respectively connected to the sensor junction box 44 and the water pump junction box 49, the sensor junction box 44 is a three-outlet, the sensor junction box 44 is respectively connected to the oxygen concentration sensor 46 and the liquid level transmitter 410, the water pump junction box 49 is connected to the DC water pump 47, the above-mentioned wire ends are waterproofed by filling and sealing, one end of the water pipe is connected to the rotating end 161 of the rotary joint 16, and the water sample flows out from the fixed end 162, the rotary joint 16 is a conventional means, with the above arrangement, when the reel core shaft 112 rotates, the water pipe and the wire will not be twisted together, the other end passes through a plurality of threading plates 23 along the chain 2 in sequence and is connected to the DC water pump 47.

[0064] During the use of the automatic profile lifting device, when it needs to be lowered, the roller motor 39 and the chain motor 15 respectively drive the roller 33 and the reel core shaft 112 to rotate, and the chain 2 drives the submersible pump mechanism 4 to move downward along the roller 33. Since the maximum bending angle of the chain 2 upward is 180°, the chain 2 will not sag when moving between the chain mechanism 1 and the roller 33, thereby affecting the lifting efficiency. During the descent, the water pipe unfolds with the chain 2, and the rotating end 161 is driven to rotate during the unfolding process, so that the water pipe will not be twisted together. In addition, the wire unfolds with the chain 2, and the rotor 1111 is driven to rotate during the unfolding process, so that the wire will not be twisted. When it descends to a suitable position, start the DC water pump 47 to send the water sample out of the water pipe and collect the water sample. The oxygen concentration sensor 46 and the liquid level transmitter 410 are auxiliary tools, which are all conventional technologies. When it is necessary to ascend, just rotate the roller 33 and the reel core shaft 112 in the opposite direction. When the travel switch top block 415 is located at the travel switch 2 43, stop rotating and complete the ascent. However, when the travel switch 2 43 is damaged, the travel switch top block 415 continues to rise and reaches the travel switch 1 42, which can also stop the reversely rotating roller 33 and the reel core shaft 112 from rotating. At this time, the ascent is completed. The setting of the two travel switches can ensure the smooth progress of the work.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
