Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to a water quality sampling device based on an aquatic remote-controlled robot. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The scope of water quality monitoring is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage.

[0003] The water quality monitoring process generally involves sampling and analyzing the water quality of the monitored water body to determine comprehensive indicators of water quality conditions, such as temperature, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, chemicals, heavy metals, etc.

[0004] At present, when sampling the water quality of rivers, lakes, seas and other water bodies, in addition to sampling near the shore, staff are also required to take a small boat to the water body far away from the shore to take samples. The sampling process itself is not complicated, but it requires a certain amount of manpower and time costs, which is not cost-effective for scientific researchers. They cannot use their precious time on scientific research, which to some extent affects the efficiency of water quality monitoring.

[0005] To this end, the present application proposes a water quality sampling device based on an aquatic remote-controlled robot to improve the efficiency of water quality sampling. Utility Model Content

The lead screw is longitudinally arranged at the bottom of the support frame and the upper end is transmission-connected to the drive motor. The nut sleeve is arranged on the outside of the lead screw. The clamping unit is connected to one side of the nut. The guide rod is longitudinally arranged on the other side of the lead screw and the upper end is fixedly connected to the bottom of the support frame. The nut is slidably connected to the guide rod via a sliding sleeve.

[0008] Furthermore, the clamping unit includes a connecting seat and a group of symmetrically arranged clamping arms, one end of the clamping arm is rotatably arranged on the connecting seat through a torsion spring, and the connecting seat is fixedly connected to the side wall of the nut.

[0009] Furthermore, the clamping arm is composed of two strip plates arranged at an obtuse angle.

[0011] Furthermore, a first limit block is provided at the lower end of the lead screw, and a second limit block is provided at the lower end of the guide rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-2As shown, the water quality sampling device based on the aquatic remote-controlled robot in this embodiment includes a robot body 1, a support frame 2 and a sampling mechanism. The support frame 2 spans above the robot body 1, and the sampling mechanism is arranged on the support frame 2. The sampling mechanism includes a drive motor 3, a controller 4, a transmission assembly and a sampler 5. The drive motor 3 and the controller 4 are both arranged above the support frame 2 and the two are electrically connected. The transmission assembly is arranged at the bottom of the support frame 2 and is transmission-connected to the drive motor 3, and the sampler 5 is arranged on the transmission assembly.

[0020] Among them, the robot body 1 adopts the ROV water lifesaving remote control robot in the prior art, which can be remotely controlled by a remote control to drive the robot body 1 on the water surface; the controller 4 adopts the GV-DJ401S remote control motor forward and reverse controller, which can remotely control the forward and reverse rotation of the drive motor 3, thereby driving the transmission assembly and the sampler 5 to move, and realize water sampling; the sampler 5 can be a tubular or cup-shaped container.

[0021] like Figure 2 As shown, the transmission assembly includes a lead screw 6, a nut 7, a clamping unit 8 and a guide rod 9. The lead screw 6 is longitudinally arranged at the bottom of the support frame 2 and the upper end is transmission-connected to the drive motor 3. The nut 7 is sleeved on the outside of the lead screw 6. The clamping unit 8 is connected to one side of the nut 7. The guide rod 9 is longitudinally arranged on the other side of the lead screw 6 and the upper end is fixedly connected to the bottom of the support frame 2. The nut 7 is slidably connected to the guide rod 9 via a sliding sleeve 10.

[0022] A first limit block 61 is disposed at the lower end of the lead screw 6, and a second limit block 91 is disposed at the lower end of the guide rod 9, which are respectively used to limit the nut 7 and the sliding sleeve 10 to prevent the two from falling off.

[0023] A plug 11 is also provided at a position at the bottom of the support frame 2 corresponding to the sampler 5 , which is used to block the water inlet at the upper end of the sampler 5 .

[0024] like Figure 3 As shown, the clamping unit 8 includes a connecting seat 81 and a group of symmetrically arranged clamping arms 82. One end of the clamping arm 82 is rotatably set on the connecting seat 81 through a torsion spring 83, and the connecting seat 81 is fixedly connected to the side wall of the nut 7; wherein, the clamping arm 82 is composed of two strip plates set at an obtuse angle, which can adapt to the clamping requirements of samplers 5 of various sizes.

[0025] When sampling, the driving motor 3 drives the lead screw 6 to rotate, so that the nut 7 moves downward along the lead screw 6 until the sampler 5 is submerged in the water; the driving motor 3 pauses for a while, and then reverses after the sampler 5 is filled with water, driving the nut 7 to move upward along the lead screw 6, so that the water inlet at the upper end of the sampler 5 is connected to the plug 11, and the plug 11 squeezes out excess water and seals the water inlet. It should be noted that the plug 11 does not need to be sealed with the water inlet of the sampler 5, as long as it can play a role in preventing water leakage, so as to prevent the robot body 1 from bumping when driving back to the shore, causing excessive water leakage in the sampler 5.

[0026] After the sampling is completed, the staff can operate the remote control to make the robot body 1 return to the shore, and then remove the sampler 5 from the clamping unit 8. There is no need for the staff to personally drive the boat to take samples, which saves a lot of time and labor costs and improves the efficiency of water quality sampling.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
