Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality detector capable of detecting water quality at different depths. Background Art

[0002] Water is the source of life. The decline in drinking water quality will cause great harm to human health, so water quality testing plays an important role in environmental protection and water resource protection. Nowadays, professionals will use a special water quality detector to test water resources. The water quality detector is a professional instrument used to analyze the content of water quality components. It measures BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, PH, dissolved oxygen and other items in water.

[0003] For example, the utility model with application number CN202020951371.9 discloses a water quality detector, which provides a winding frame on one side of the detector to wind the wire, and provides a fixing part, a locking part and a limit part to facilitate the limiting of the sleeve, and a limiting groove is provided on the top of one side of the winding frame, which cooperates with a silicone pad to facilitate the limiting of the wire. When the detector is in use, the wire will not fall off at will, and the operation is simple and convenient, and it is convenient to store the probe and the wire. However, when the water quality detector measures the water quality, it is necessary to use a sampling bottle to take samples from the water source area to be measured, and then place the water sample in the sampling bottle into the water quality detector to detect the water quality. This process is relatively cumbersome. If the detection head of the detector is directly put into the water, foreign matter in the water, such as algae, will adhere to the surface of the detection head, thereby affecting its detection effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a water quality detector that can detect water quality at different depths is proposed. Utility Model Content

[0012] The utility model provides a water quality detector capable of detecting water quality at different depths, which has the following beneficial effects:

[0013] 1. The utility model can form a protective cover on the outside of the detection head by arranging a weighted shell and a protruding shell, so as to avoid the detection head being directly exposed and the algae in the water area adhering to its surface, thereby improving the overall detection effect of the water quality detector. At the same time, under the design of the auxiliary components, a small forward and reverse motor can be used to drive the rotation of the threaded column so that it can be threadedly connected with the threaded layer connected to the inner wall of the outer column to drive the piston to move upward, so that water can enter from the water inlet and then enter the weighted shell through the water hole for storage. In this way, the effect of automatic sampling can be achieved, and the detection head can directly detect the water quality, thereby avoiding the traditional need to use a sampling bottle to go to the water source area to be measured to sample, and then place the water sample in the sampling bottle into the water quality detector for detection.

[0014] 2. The utility model can utilize the telescopic relationship between the fixed outer cylinder and the extension cylinder through the arrangement of the fixed outer cylinder, the extension cylinder, the wavy wire and the limit mechanism, so that the water quality detector can be conveniently carried and stored. At the same time, with the installation of the scale, the fixing ring and the float, the water quality detector can detect water quality at different depths, thereby improving the performance of the water quality detector. The arrangement of the fixed component can utilize the threaded connection between the threaded cylinder seat and the adjusting screw and the mortise and tenon connection between the plug column and the plug hole, which makes it convenient for people to limit and adjust the position of the float, thereby improving the flexibility of the water quality detector when used.

The output end of the small forward and reverse motor 801 is provided with a threaded column 802, and the outer surface of the threaded column 802 is installed with a connecting outer column 803, and the end of the connecting outer column 803 is provided with a piston 804. The bottom surface of the protruding shell 7 is provided with a water inlet 805, and the side surface of the protruding shell 7 close to the weighted shell 5 is provided with a water hole 9. The installation of the auxiliary component 8 and the water hole 9 can avoid the traditional need to use a sampling bottle to go to the water source area to be measured to take samples, and then place the water sample in the sampling bottle into a water quality detector for testing.

[0022] like Figure 2 and Figure 3 As shown, a wavy wire 10 is arranged inside the fixed outer cylinder 3, and a limiting mechanism 11 is installed on the lower side of the outer surface of the fixed outer cylinder 3 and the extension cylinder 4. The arrangement of the fixed outer cylinder 3, the extension cylinder 4, the wavy wire 10 and the limiting mechanism 11 makes it convenient to carry and store the water quality detector. The outer surfaces of the fixed outer cylinder 3 and the extension cylinder 4 are provided with scales 12, and the extension cylinder 4 is provided with a fixing ring 13 on the outside, and a floating ball 14 is arranged on the outer surface of the fixing ring 13, and a fixed ball 14 for limiting its position is installed on the inner side of the fixing ring 13. The fixed component 15 includes a threaded cylinder seat 1501 and an adjusting screw 1502. The adjusting screw 1502 is connected to the inside of the threaded cylinder seat 1501. The fixed component 15 also includes a plug post 1503 and a socket 1504. The end of the adjusting screw 1502 is provided with a plug post 1503, and the extension tube 4 is provided with a socket 1504 on one side close to the plug post 1503. The installation of the scale 12, the fixing ring 13, the float 14 and the fixed component 15 enables the water quality detector to detect water quality at different depths.

[0023] In summary, the water quality detector that can detect water quality at different depths first Figure 1 , Figure 2 , Figure 3 and Figure 4When using the structure shown in , people can adjust the length of the fixed outer tube 3 on the water quality detector according to the detection needs. At this time, people can pull the extension tube 4 hidden inside the fixed outer tube 3. After it is fully pulled out, the limited mechanism 11 can be used to fix the position of the pulled extension tube 4 (at this time, people can press one end of the long block on the limiting mechanism 11 to make it rotate with the rotating seat, and squeeze the spring on the inner side of one end of the long block to make it contract and absorb energy, so that the convex block at the other end of the long block is away from the limiting hole on the extension tube 4, so that it can be pulled out. When the extension tube 4 is fully pulled out, the long block can be released. Since there is no external force squeezing, the spring will drive the long block to reset, so that the convex block can be stuck into another one on the extension tube 4. The extension tube 4 is fixed in the limiting hole to complete the fixation of the extension tube 4), and then people can pull out several sections of the extension tube 4 of the required length in the same way, and then according to the scale 12 on the extension tube 4, move the fixing ring 13 to the socket 1504 corresponding to the required scale 12. After moving and determining the position, the adjusting screw 1502 on the fixing ring 13 can be manually rotated clockwise to make it threadedly connected with the threaded tube seat 1501, so as to drive the plug column 1503 at the end of the adjusting screw 1502 to gradually approach the socket 1504, and stop rotating the adjusting screw 1502 when the mortise and tenon connection occurs, and then rotate the adjusting screw 1502 on the other side of the fixing ring 13 in the same way, so as to After the fixing ring 13 is fixed, people can hold the fixed outer tube 3 and put the weighted shell 5 at the end of the extension tube 4 connected to it into the water area to be tested. Due to the weight of the weighted shell 5 itself, the extension tube 4 can be driven to sink together. While sinking, the float 14 on the fixed ring 13 will float on the water surface, so it will limit the sinking depth of the extension tube 4. Therefore, people can make the water quality detector capable of testing water quality at different depths through the design of its structure. When the weighted shell 5 reaches the specified water depth, the small forward and reverse motor 801 (model 70KTYZ) protruding from the shell 7 can be controlled to start, so that it drives the threaded column 802 at the output end. It rotates so that it can be threadedly connected with the threaded layer connected to the inner wall of the outer column 803, which can drive the piston 804 connected to it to move upward. Because it continues to move upward, negative pressure is generated inside the protruding shell 7, and water in the water area is sucked into the protruding shell 7 through the water inlet 805. As the water enters, it will continue to enter the weighted shell 5 for storage through the water hole 9. At this time, the water level inside it will rise, so the detection head 6 at the top of the weighted shell 5 will detect the incoming water, and the detection result will be transmitted through the wave conductor 10 and the data conductor 2, and displayed on the display screen of the water quality detection display terminal 1 (which is the existing technology) for personnel to understand and record.
