Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a lake water sampling device for environmental monitoring. Background Art

[0002] During environmental testing of lake water quality, it is necessary to take some lake water samples and then analyze the substances contained in the water samples for later treatment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] At present, in order to effectively collect lake water samples at different depths, existing equipment is usually equipped with multiple sampling cylinders, and these sampling cylinders are placed together layer by layer. Although this design allows lake water of different depths to enter each sampling cylinder separately, making it convenient to obtain multi-layer water samples, the height stacking of multiple sampling cylinders will cause the overall height of the entire equipment to increase, which will cause great inconvenience to staff when carrying the equipment out for sampling.

[0023] To solve the above defects in the process of carrying the sampling equipment, please refer to Figure 1-Figure 5 The utility model provides a lake water sampling device for environmental monitoring, which can not only sample lake water at different depths, but also can shrink multiple sampling tubes to reduce the space occupied by the equipment and facilitate carrying. The sampling device is based on a suspension rod 1. The bottom of the suspension rod 1 is fixedly connected to a sampling tube 1 2. The lower end of the sampling tube 1 2 is slidably provided with a sampling tube 2 3. The lower end of the sampling tube 2 3 is slidably provided with a sampling tube 3 4. A clamping piece 1 5 is provided between the sampling tube 2 3 and the sampling tube 3 4. The clamping piece 1 5 includes a pressure rod 51 symmetrically slidably installed on both sides of the sampling tube 2 3. The interior of the sampling tube 2 3 is provided with a slide groove 52 for the pressure rod 51 to slide. A spring 1 53 is installed between the pressure rod 51 and the inner wall of the slide groove 52, and a block 54 is provided at the lower end of the pressure rod 51. The inner wall of the sampling tube 3 4 is provided with a groove adapted to the block 54. A clamping piece 2 8 is provided between the sampling tube 1 2 and the sampling tube 2 3. The structure is the same as that of the clamping piece 5. When the equipment is not in use, the sampling cylinder 1 2 is in the sampling cylinder 2 3, and the sampling cylinder 2 3 is in the sampling cylinder 3 4. When sampling, pressing the pressure rod 51 drives the block 54 to contract. At this time, the spring 1 53 is deformed, and the sampling cylinder 2 3 is pulled out from the sampling cylinder 3 4 until the block 54 in the sampling cylinder 2 3 is aligned with the slot on the sampling cylinder 3 4. The pressure rod 51 can push the block 54 into the slot through the elastic force of the spring 1 53, so that the sampling cylinder 2 3 can be fixed to the upper end of the sampling cylinder 3 4. Similarly, the sampling cylinder 1 2 can be pulled out and fixed to the upper end of the sampling cylinder 2 3 through the clamping piece 2 8. Then the equipment is extended into the lake to sample lake water of different depths.

[0024] When sampling, lake water needs to enter sampling tube 1 2, sampling tube 2 3 and sampling tube 3 4. Therefore, sampling tube 1 2, sampling tube 2 3 and sampling tube 3 4 are all provided with sampling holes 6, and the outer walls of sampling tube 1 2, sampling tube 2 3 and sampling tube 3 4 are all provided with sealing parts 7 for sealing the sampling holes 6. The opening and closing of the sampling holes 6 can be controlled by the sealing parts 7. When the equipment is extended into the lake to a certain height, the sampling holes 6 are controlled to open, and lake water of different depths can enter each sampling tube 1 2, sampling tube 2 3 and sampling tube 3 4 respectively. The interior of sampling tube 2 3 and sampling tube 3 4 are both provided with collection ring grooves 10, and the interior of sampling tube 1 2 is provided with a collection hole 11. The collection ring groove 10 and the collection hole 11 are used to store the collected lake water.

[0025] In order to achieve the opening and closing control effect of the above-mentioned sealing member 7 on the sampling hole 6, a side frame 71 is provided which is fixedly mounted on the outer wall of the sampling tube 1 2, the sampling tube 2 3 and the sampling tube 3 4 respectively. The inside of the side frame 71 is slidably connected with an electromagnetic door 72. A spring 2 73 is installed between the electromagnetic door 72 and the inner wall of the side frame 71, and an iron plate 74 is installed on the end of the side frame 71 away from the spring 2 73. Figure 4 The electromagnetic door 72 shown is in the energized state. When the device is extended into the lake, the electromagnetic door 72 is energized to generate magnetic force, which is attracted by the iron plate 74 and merges with the iron plate 74. At this time, the electromagnetic door 72 can block the sampling hole 6, and the spring 2 73 is in a deformed state. When the device reaches the specified height, the power of the remote-controlled electromagnetic door 72 is disconnected, and the electromagnetic door 72 is separated from the iron plate 74 by the elastic force of the spring 2 73. The electromagnetic door 72 slides along the side frame 71 to open the sampling hole 6, and lake water at different levels can enter the collection ring groove 10 and the collection hole 11 respectively from the sampling hole 6.

[0026] When the equipment is not in use, sampling tube 1 2 is in sampling tube 2 3, and sampling tube 2 3 is in sampling tube 3 4. In order to prevent sampling tube 1 2 and sampling tube 2 3 from sliding out automatically, a tube cover 9 is slidably connected to the outside of the boom 1, and the upper end of the sampling tube 3 4 is threadedly connected to the inner wall of the tube cover 9. Slide the tube cover 9 to the upper end of the sampling tube 3 4 and rotate the tube cover 9 to install it on the sampling tube 3 4. In this way, sampling tube 1 2 and sampling tube 2 3 can be confined in the sampling tube 3 4 and the tube cover 9.

[0027] In order to facilitate the throwing of the equipment into the lake, there is a winding roller 12 arranged above the boom 1, and a lifting rope 13 is wound on the winding roller 12. One end of the lifting rope 13 is fixedly connected to the outside of the winding roller 12, and the other end of the lifting rope 13 is fixedly connected to the top of the boom 1. A handwheel is provided on one side of the winding roller 12, and a handle 14 is installed on the top of the winding roller 12. The handle 14 facilitates the movement of the lifting equipment. The winding roller 12 is used to control the retraction and extension of the lifting rope 13. The retraction and extension of the lifting rope 13 can control the depth of the boom 1 in the lake, which makes it convenient to throw the boom 1 into the lake or pull it out of the lake.

[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0029] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
