Description

Technical Field

[0001] The utility model relates to a water quality sampling device, in particular to a water quality sampling device based on water pollution control, belonging to the technical field of water quality sampling. Background Art

[0002] Water pollution refers to the change of chemical, physical, biological or radioactive properties of water due to the intervention of certain substances, which affects the effective use of water, endangers human health or damages the ecological environment. Therefore, it is necessary to sample and test the water quality and treat the water body in time to avoid the deterioration of water quality.

[0003] A water pollution detection and sampling device for environmental protection and management disclosed in the Chinese patent application publication specification CN211292118U, through the continuous movement of the box body relative to the counterweight block, the upper and lower positions of the collection hole relative to the upper limit block are further controlled to control the opening and closing of the water storage bin, thereby effectively obtaining the water quality at the bottom of the water.

[0004] In actual applications, it was found that when the stable sampling device for water pollution control is used for sampling in deeper water sources, the box is subjected to increasing pressure from the water body. When the pressure on the box is greater than the tension of the connecting rod and the lower limit block, the upper limit block will drop, and the water will enter the box from the collection hole, making it impossible to sample the water at the bottom of the water source well.

[0031] The embodiment of the utility model provides a water quality sampling device based on water pollution control.

[0032] Please refer to Figure 1 and Figure 2 A water quality sampling device based on water pollution control includes a filtering mechanism 1, which includes a protective shell 101. The inner top wall of the protective shell 101 is fixedly connected to the top surface of a sampling tube 201. Filter nets 102 are fixedly installed on the four sides of the protective shell 101. Four connecting blocks 103 fixedly connected to the side surfaces of the sampling tube 201 are fixedly connected to the inner side wall of the protective shell 101. A through groove 104 is opened on the front of the protective shell 101. The front of the sampling tube 201 is fixedly connected to a water outlet valve 5 that penetrates the through groove 104.

[0033] The sampling tube 201 can be protected by the protective shell 101, and the impurities in the water source can be filtered through the filter net 102, thereby improving the quality of water sampling at the bottom of the water source. The through groove 104 is provided to facilitate the installation of the water outlet valve 5, and the water body after sampling can be collected through the water outlet valve 5 for subsequent testing.

[0034] Please refer to Figure 3 , Figure 4 and Figure 7 The sampling mechanism 2 is fixedly connected to the inside of the filtering mechanism 1. The sampling mechanism 2 includes a sampling cylinder 201 fixedly connected to the filtering mechanism 1. The four sides of the sampling cylinder 201 are fixedly inlaid with sealing blocks 202. The four sealing blocks 202 are each provided with a movable groove 203 inside. The four sealing blocks 202 are each provided with a water inlet 204 penetrating the sealing blocks 202.

[0035] The top surfaces of the four movable grooves 203 are fixedly connected with compression springs 205, the lower ends of the four compression springs 205 are fixedly connected with sealing plates 206 that are slidably connected to the movable grooves 203, and the four sealing plates 206 are provided with water inlet grooves 207. The sampling mechanism 2 also includes a counterweight base 208 fixedly connected to the lower ends of the four sealing plates 206.

[0036] The upper end of the sealing plate 206 can close the water inlet 204, thereby preventing water from flowing into the sampling tube 201 from the water inlet 204 during the process of the device descending in the water source. When the counterweight base 208 contacts the bottom of the water source and the device continues to descend, the sealing plate 206 will move upward relative to the sampling tube 201 until the water inlet trough 207 moves to the water inlet 204. At this time, the water inlet 204 is unblocked, and the water at the bottom of the water source will enter the interior of the sampling tube 201 from the water inlet 204, thereby completing the collection of the water at the bottom of the water source.

[0037] After the collection is completed, the device is pulled upwards, and the elastic force generated by the deformation of the compression spring 205 can drive the sealing plate 206 to move downward relative to the sampling tube 201, so that the upper end of the sealing plate 206 closes the water inlet 204 again, making it impossible for water at other depths of the water source to enter the interior of the sampling tube 201, thereby ensuring the accuracy of the water collection at the bottom of the water source.

[0038] Please refer to Figure 7 Sealing gaskets 209 are fixedly installed in all movable grooves 203 and water inlets 204, and four sealing plates 206 are in sliding contact with the sealing block 202 through the sealing gaskets 209. By setting the sealing gaskets 209, the sealing performance of the device can be improved to prevent water from other depths of the water source from entering the interior of the sampling tube 201.

[0039] Please refer to Figure 6 The four corners of the counterweight base 208 are provided with reinforcement mechanisms 3, and the reinforcement mechanisms 3 include threaded sleeves 301 fixedly embedded in the corners of the counterweight base 208, the internal threads of the threaded sleeves 301 are connected with threaded rods 302, the lower end of the threaded rods 302 is fixedly connected with spikes 303, and the upper end of the threaded rods 302 is fixedly connected with rotating rods 304, and the outer contour of the rotating rods 304 is a cylinder.

[0040] The rotating rod 304 can provide a reasonable force point for rotating the threaded rod 302, and the rotating threaded rod 302 will be spirally lifted and lowered in the threaded sleeve 301. The cooperation between the threaded rod 302 and the spike portion 303 can improve the stability of the device in sampling at the bottom of the water source.

[0041] Please refer to Figure 5The top surface of the filtering mechanism 1 is provided with a telescopic mechanism 4 including a U-shaped mounting frame 401 fixedly connected to the top surface of the protective shell 101, the top surface of the U-shaped mounting frame 401 is fixedly connected with a fixed cylinder 402, the inner wall of the fixed cylinder 402 is slidably connected with a telescopic cylinder 403, and the fixed cylinder 402 and the telescopic cylinder 403 are both provided with evenly distributed limiting holes 404, the upper end of the fixed cylinder 402 is fixedly connected with two threaded blocks 405 corresponding to the limiting holes 404, the internal threads of the threaded blocks 405 are connected with bolts 406, and the upper end of the telescopic cylinder 403 is fixedly connected with a fixing ring 407.

[0042] The fixing ring 407 makes it easy to fix the device on the existing lifting equipment so as to sample the water at the deeper bottom of the water source. The matching arrangement of the threaded block 405, the bolt 406 and the limiting hole 404 can effectively fix the fixed tube 402 and the telescopic tube 403. By adjusting the length between the fixed tube 402 and the telescopic tube 403, it is possible to sample the water at the bottom of the water source at different depths. The diameter value of the limiting hole 404 is matched with the diameter value of the bolt 406, so that the bolt 406 can be inserted into the limiting hole 404 opened on the telescopic tube 403.

[0043] When the utility model is in use: the fixing ring 407 is used to conveniently fix the device on the existing lifting equipment, and then the device is slowly placed in the water. When the counterweight base 208 contacts the bottom of the water source, the device continues to be lowered, and the sealing plate 206 will move upward relative to the sampling tube 201 until the water inlet trough 207 moves to the water inlet 204. At this time, the water inlet 204 is unblocked, and the water at the bottom of the water source will enter the interior of the sampling tube 201 from the water inlet 204, thereby completing the collection of the water at the bottom of the water source.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
