Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring and water quality testing technology, specifically relating to a portable SDI pollution index detection device. Background Technology

[0002] The SDI pollution index detection device is mainly used for rapid and convenient detection of the pollution density index (SDI) of water bodies. In practical applications, it can conduct on-site testing of various water samples, such as drinking water sources, industrial production water, and sewage treatment plant effluent. By accurately measuring the degree of clogging of specific microporous filter membranes by pollutants such as suspended particles and colloids in the water, the SDI value can be calculated.

[0003] While some existing SDI pollution index detection devices are equipped with portable cases or backpacks designed to improve portability, in actual operation, testing personnel often have to unfasten multiple buckles or unzip long zippers one by one. This process is extremely cumbersome. In real-world testing scenarios where every second counts, each time the device is turned on, a significant amount of time is wasted, greatly reducing overall work efficiency. Over time, the originally expected testing cycle may be significantly extended, seriously affecting the timeliness and continuity of testing work, thus making it difficult to meet the needs of efficient water quality testing.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is an embodiment of the present invention, which provides a portable SDI pollution index detection device, comprising:

[0028] The measuring mechanism 100 includes a measuring instrument body 101, and a display panel 102 and a control panel 103 adapted to be installed on the outer surface of the measuring instrument body 101.

[0029] It should be noted that the instrument body 101 is used to perform the actual measurement function of SDI pollution index detection, and the display panel 102 is used to display the detection data and related information for easy viewing by the user. The user can set the detection parameters, start or stop the detection and other operations through the control panel 103.

[0030] The disassembly and assembly mechanism 200 includes a bearing component 201 disposed on the outside of the measuring instrument body 101, an inner support component 202 disposed on the outer surface of the bearing component 201 and capable of circular expansion outward, and a connecting component 203 fixedly connected to the top of the measuring instrument body 101 and used in conjunction with the inner support component 202 to connect the measuring instrument body 101 and the bearing component 201.

[0031] Specifically, the bearing assembly 201 includes a fixed plate 201a disposed on the outside of the measuring instrument body 101, a telescopic rod 201b fixedly connected to the center position of the outer surface of the fixed plate 201a, a star-shaped guide rail 201c fixedly sleeved on the outer surface of the telescopic rod 201b, and a pull block 201d fixedly installed on the outer end face of the telescopic rod 201b.

[0032] It should be noted that the fixed plate 201a is used to provide an installation base for other components, the length of the telescopic rod 201b can be extended or retracted according to actual usage needs, thereby adjusting the overall structural state of the device, the star-shaped guide rail 201c is used to provide a sliding track for the Z-shaped rod 202h, and the pull block 201d facilitates the user to carry the device or operate the extension and retraction of the telescopic rod 201b.

[0033] Furthermore, the inner support assembly 202 includes a fixing block 202a fixedly connected to the outer surface of the fixing disk 201a, a knob 202b fixedly mounted to the outer surface of the fixing block 202a via a bearing, a worm gear 202c fixedly connected to the through end of the knob 202b, a worm wheel 202d meshing with the outer surface of the worm gear 202c, and a turntable 202e fixedly connected to the inner surface of the worm wheel 202d.

[0034] Preferably, a bearing sleeve that rotates in coordination is installed at the connection between the fixing block 202a and the knob 202b, and the turntable 202e is rotatably sleeved on the outer surface of the telescopic rod 201b.

[0035] It should be noted that the inner support assembly 202 also includes several arc grooves 202f penetrating the surface of the turntable 202e, movable blocks 202g movably connected to the inner wall of the arc grooves 202f, Z-shaped rods 202h fixedly installed on the outer end face of the movable blocks 202g, positioning posts 202i fixedly connected to the other end of the Z-shaped rods 202h, and several through grooves 202j penetrating the surface of the fixed plate 201a and used in conjunction with the Z-shaped rods 202h.

[0036] It should also be noted that the fixed block 202a is used for installation, and the knob 202b can drive the worm gear 202c to rotate synchronously by rotating the knob 202b, which in turn drives the worm wheel 202d and the turntable 202e to rotate synchronously. When the turntable 202e rotates, it can drive the movable block 202g to move along the inner wall of the arc groove 202f, so that the Z-shaped rod 202h drives the positioning column 202i to expand outward along the inner wall of the star-shaped guide rail 201c as the movable block 202g moves.

[0037] Furthermore, the arc grooves 202f are distributed in a circular array on the surface of the inner support assembly 202, the outer surface of the Z-shaped rod 202h slides in contact with the inner wall of the star-shaped guide rail 201c, and the through grooves 202j are distributed in a circular array on the surface of the fixed disk 201a.

[0038] Specifically, the connecting component 203 includes a fixing sleeve 203a fixedly connected to the outer surface of the measuring instrument body 101, and a plurality of positioning holes 203b penetrating the surface of the fixing sleeve 203a and used in conjunction with the through groove 202j.

[0039] It should be explained that by the cooperation of the fixing sleeve 203a and the positioning hole 203b, the protruding positioning post 202i can be limited, thereby connecting the measuring instrument body 101 and the bearing component 201.

[0040] Furthermore, the positioning holes 203b are arranged in a circumferential array on the surface of the fixed sleeve 203a, and the outer surface of the through groove 202j slides in contact with the inner wall of the positioning holes 203b.

[0041] In use, the telescopic rod 201b is extended or retracted by pulling the lever 201d to adapt to the carrying or operation needs of different usage scenarios. Then, the knob 202b is turned to drive the worm gear 202c to rotate. Through the cooperation of the worm gear 202c and the worm wheel 202d, the turntable 202e is driven to rotate synchronously.

[0042] When the turntable 202e rotates: it pushes the movable block 202g to move along the inner wall of the arc groove 202f, and drives the Z-shaped rod 202h to slide along the inner wall of the star-shaped guide rail 201c through the movable block 202g. At the same time, the positioning column 202i expands outward synchronously with the movement of the Z-shaped rod 202h. After the positioning column 202i extends out of the through groove 202j of the fixed plate 201a: the connection and fixation of the measuring instrument body 101 and the bearing component 201 are completed.

[0043] During testing: Rotate knob 202b in the reverse direction to retract positioning post 202i and disengage it from positioning hole 203b, thus separating the measuring instrument body 101 and the support assembly 201, preparing for the use of the measuring instrument body 101. Set the required testing parameters on control panel 103, such as testing time and water sample type. After setting, start the testing operation. The measuring instrument body 101 begins to perform the actual measurement of SDI pollution index. During this process, the water sample undergoes specific treatment, and the device analyzes the processed data according to relevant principles. After the measurement is completed, the test data and related information will be displayed on display panel 102 for the user to view the results.

[0044] In summary, through the cooperation of the bearing component 201, the inner support component 202, and the connecting component 203, compared to unfastening multiple buckles or zippers, the disassembly and assembly of the instrument body 101 and the bearing component 201 can be quickly completed by simply turning the knob 202b. This avoids the problem of extending the testing cycle due to the excessive time required to open the device, ensuring the timeliness and continuity of the testing work. It provides a convenient user experience for testing personnel while also meeting the needs of efficient water quality testing.
