Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, specifically relating to a portable water toxicity testing device. Background Technology

[0002] Water is the source of life, and humans cannot live without it. The quality of drinking water is closely related to human health. Water toxicity refers to the harmful effects of a substance on organisms in aquatic bodies. This effect can be direct or indirect, usually resulting in the deterioration of an organism's health or even death after ingestion. The detection of water toxicity is of great significance in environmental protection and water quality management. By detecting water toxicity, water pollution can be detected and treated in a timely manner, protecting the ecological environment and human health.

[0003] Patent application CN201521046586.1 discloses a portable water toxicity detection device based on microbial electrochemical signals. The device includes a base plate mounted on legs, a ball screw mounted on the base plate and connected to a drive motor mounted on the base plate, clamping plates on both sides of the ball screw, a top plate fixed to the top of the clamping plates, a screw nut fitted onto the ball screw, a cylinder connected to the screw nut via a bracket, a strip-shaped biosensor mounted at the lower end of the top plate, and a detection port corresponding to the strip-shaped biosensor on the cylinder. An analysis module and a display module are both mounted on the top of the top plate; the analysis module is connected to the strip-shaped biosensor, and the display module is connected to the analysis module. This invention can automatically control the lifting and lowering of the cylinder, thereby enabling the strip-shaped biosensor to detect the water quality within the cylinder, avoiding secondary pollution caused by manual operation. However, the actual detection process requires testing multiple samples, and using a single cylinder lifting and lowering mechanism in conjunction with the biosensor results in low efficiency. Therefore, this application provides a portable water toxicity detection device that improves detection efficiency.

[0033] See attached document Figure 1-6 A portable water toxicity detection device, comprising:

[0034] The base 1 has a first clearance groove 2 and a second clearance groove 3; a ball-head plunger 4 is provided on each side of the base 1.

[0035] The first support assembly, located above the base 1, includes a fixed seat 5, a support rod 6, and a support rod 7. The fixed seat 5 is fixed to the front end of the base 1. The support rod 6 has a guide groove 8, one end of which is hinged to the fixed seat 5 and the other end of which is hinged to the support rod 7. The guide groove 8 has multiple water-holding frames 9, which are located above the clearance groove 2. The support rod 7 has a limit groove 10 at the end away from the support rod 6.

[0036] The second support assembly, located above the base 1, includes a second fixed seat 11, a third support rod 12, and a fourth support rod 13. The second fixed seat 11 is fixed to the front end of the base 1. One end of the third support rod 12 is hinged to the second fixed seat 11, and both sides of it are provided with sliding grooves 14 and the top is provided with an electric push rod 15. The fourth support rod 13 is located above the second clearance groove 3, and one end of it is provided with two symmetrical extension plates 16 and the other end is provided with a second limiting groove 17. The inner side of the extension plate 16 is provided with a limiting post 26, and the limiting post 26 is located in the corresponding sliding groove 14.

[0037] The locking assembly includes two movable plates 18 and one limiting rod 19; the two movable plates are located on both sides of the base 1, and two limiting holes 20 are provided on them to cooperate with the ball plunger 4; a limiting plate 21 is provided at the end of the movable plate 18 away from the fixed seat 5, and two clearance holes 22 are provided on the limiting plate 21; the limiting rod 19 passes through the limiting groove 10, the limiting groove 17 and the two clearance holes 22 at the same height, and is locked by a nut;

[0038] The biosensor 23 is fixed to the bottom of the movable end of the electric actuator 15 and located above the water-holding frame 9 at the front end. The biosensor 23 is characterized by its small size, fast response, and ability to perform online monitoring. It is commonly used in environmental monitoring. During use, it transmits electrochemical signals, and the analysis results can be displayed on a screen. Optional biosensors 23 for detecting water toxicity include: Holder HD-DXS, Amphenol NPC-120T, and TOKE TK020AM00 / BS, etc. The specific choice depends on the actual application scenario.

[0039] In this embodiment, the top of the electric push rod 15 is provided with a load-bearing plate 24, and a guide groove 25 is provided on the load-bearing plate 24; the top of the support rod 12 is provided with a limiting post 26, which passes through the guide groove 25 and is fixed to the load-bearing plate 24 by bolts. The operator can adjust the position of the electric push rod 15 by adjusting the position of the limiting post 26 in the guide groove, thereby adjusting the position of the biosensor 23 above the water holding frame 9 until the lower tactile section of the biosensor 23 can smoothly enter the water holding frame 9. When conducting water quality testing, the movable end of the electric push rod 15 drives the biosensor 23 to extend downward below the water surface; when the testing is completed or when it is necessary to remove and switch the water holding frame 9, the electric push rod 15 drives the biosensor 23 to move upward.

[0040] In addition, a baffle is provided on the side of the fixing seat 2 11 away from the locking assembly, and the inner side of the baffle is in contact with the front end face of the support rod 3 12. When the support rod 3 12 rotates along the fixing seat 2 11 to a vertical position, the inner side of the baffle abuts against the front end face of the support rod 3, keeping the support rod 3 12 in a vertical position and preventing the support rod 3 12 from turning over.

[0041] It should be noted that a notch 27 is provided on the side wall of the support rod 6 near the fixed base 5, which connects to the guide groove 8; a clearance groove 28 is provided on one side of the base 1, which corresponds to the position of the notch 27; the clearance groove 28 is connected to the clearance groove 2, and its width is greater than the width of the water frame 9, so that the front water frame 9 can be easily moved out from the notch 27 through the clearance groove 28, making room for the subsequent water frame 9 to be tested. This process is repeated, which helps to speed up the testing efficiency.

[0042] On the other hand, the base 1 includes an integrally formed first base plate 29 and a second base plate 30; the front end of the first base plate 29 and the front end of the second base plate 30 are flush, and their rear ends extend beyond the rear end of the second base plate 30, which facilitates the flat placement of the first support assembly and the second support assembly for easy storage. The second base plate 30 is located on the first base plate 29, and two movable plates 18 are located on the first base plate 29 and on both sides of the second base plate 30. The movable plates 18 remain on the first base plate 29 during movement along the side wall of the second base plate 30. Two ball-head plungers 4 are respectively disposed on the side walls of the second base plate 30, and cooperate with the limiting holes 20 on the movable plates 18 to stop the movable plates 18 at specific positions, so that the first support assembly and the second support assembly remain in a flat or usable state. The flat state is shown in the attached figure. Figure 6 As shown in the attached diagram, the usage status is as follows. Figure 1 As shown.

[0043] In the first support assembly under use, support rod 6 is inclined, while support rod 7 remains vertical. At this time, the end of support rod 6 that is hinged to support rod 7 rests against a slot on support rod 7. In the second support assembly under use, support rod 12 remains vertical, while support rod 4 is inclined. It should be noted that when the first and second support assemblies are in use, the limiting rod 19 of the locking assembly passes through the limiting groove 10, the limiting groove 17, and the lower clearance hole 22 on the limiting plate 21; when the first and second support assemblies are in a flat position, the limiting rod 19 of the locking assembly passes through the limiting groove 10, the limiting groove 17, and the higher clearance hole 22 on the limiting plate 21.

[0044] This portable water toxicity testing device, through the cooperation of a first support component and a second support component with a locking component, facilitates the switching between two states: flat and in use. In the flat state, it is easy to carry and move. In the in use state, multiple water-filled frames 9 alternately slide down the support rod 6, which can quickly detect multiple water samples, thus improving detection efficiency. It is very practical and has good market application prospects.

[0045] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
