[0001] The utility model relates to the technical field of workbenches, and more specifically to an ecotoxicology test workbench. Background Art

[0002] Ecotoxicology test bench usually refers to a work platform used for ecotoxicology experiments. Ecotoxicology is a scientific field that studies the effects of chemical substances on organisms in ecosystems. It focuses on the toxic effects of chemical substances on various organisms in the environment. The bench is usually designed to conduct ecotoxicology experiments under controlled environmental conditions to evaluate the toxic effects of chemical substances on plants, animals or microorganisms in the environment, such as determining the lethal concentration, growth inhibition concentration, behavioral effects of chemical substances on organisms, etc., providing important data for environmental protection and risk assessment.

[0003] The Chinese patent publication number CN217594654U discloses an ecotoxicology test workbench. By setting up a concave-shaped workbench, the operating area of ​​the experimenter is expanded. A display screen and a camera are set on the workbench, so that video calls can be made with other scientific researchers during the operation to exchange experiments with each other. A rotatable recording table is also set on the display table to facilitate the experimenter to record experimental data. By setting up an experimental platform with grooves, the experimental platform can be rinsed after working on the experimental platform, and the sewage is discharged from the sewage outlet along the grooves around the platform to prevent the liquid of the experimental reagents and experimental samples from contaminating the workbench.

[0038] Two lighting lamps 3 are installed at the bottom end of the top frame 2, and a workbench 5 is fixedly connected to the top end of the desktop panel 8. The lighting lamps 3 are located above the workbench 5, and a plurality of through holes distributed at equal intervals are arranged at the outer end of the workbench 5.

[0039] A water tank 4 is installed on the top of the table top 8, and the water tank 4 is located below the lighting lamp 3. A plurality of universal wheels 7 are installed on the bottom end of the bottom bracket 1.

[0040] Ecotoxicology is a scientific field that studies the effects of chemical substances on organisms in an ecosystem. It focuses on the toxic effects of chemical substances on various organisms in the environment, so various chemical experiments are conducted. The device in this scheme is mainly used for experiments in ecotoxicology research. A plurality of universal wheels 7 are installed at the bottom of the bottom bracket 1. The universal wheels 7 can be used to push the device to move, making it convenient to move its position. A desktop panel 8 and a top frame 2 are installed on the top of the bottom bracket 1. The top frame 2 is L-shaped and extends to a higher area above the bottom bracket 1. Two lighting lamps 3 are installed at the bottom of the top frame 2. The lighting lamps 3 are mainly used for lighting, so as to increase the brightness of the working area and improve the visibility during work.

[0041] A water tank 4 and a workbench 5 are installed on the desktop panel 8. The water tank 4 mainly provides a water source used in experiments, which is convenient for the staff to get water. The workbench 5 is fixed above the desktop panel 8 and has a certain distance from the surface of the desktop panel 8. Through holes are also provided on the surface of the workbench 5. When a chemical experiment is performed above the workbench 5, harmful gases generated in the experiment can flow downward along the through holes and the gap between the workbench 5 and the desktop panel 8.

[0042] A grille assembly 6 is provided below the workbench 5. When the motor 97 drives the fan blades 98 to rotate, a negative pressure area is formed in the shell 96 through the air inlet channel 91 and the air inlet 93. At this time, the air around the workbench 5 is sucked into the ventilation assembly 9 through the grille assembly 6, so that the harmful gases generated when the ecotoxicology test is carried out on the workbench 5 will be extracted, thereby improving the safety of the staff when conducting the experiment.

[0043] Optionally, in some embodiments, see Figure 6 and Figure 7 Partition 1 62 and partition 2 63 are staggered, partition 1 62 is located above partition 2 63, both sides of partition 1 62 are fixedly connected with side blade plates 1 64, and side blade plates 1 64 are inclined, and both sides of partition 2 63 are fixedly connected with side blade plates 2 65, and side blade plates 2 65 are inclined.

[0044] The desktop panel 8 in this solution has a mounting groove at the outer end, and the outer frame 61 is fixed in the mounting groove so that the top of the outer frame 61 is flush with the surface of the desktop panel 8. At the same time, the outer frame 61 is below the workbench 5. A plurality of partitions 1 62 and partitions 2 63 are respectively fixed at the upper and lower positions on the inner side of the outer frame 61. The partitions 1 62 and the partitions 2 63 are equidistantly distributed. Therefore, there is a gap between each partition 1 62 and the partition 2 63. The gap is mainly used to allow air to pass through. However, the positions of the partitions 1 62 and the partitions 2 63 are staggered, so that the gap between the two partitions 1 62 is Facing the partition 2 63 below, side vanes 64 are fixed on both sides of the partition 62 and tilted downward, while side vanes 65 are fixed on both sides of the partition 63 and tilted upward. With this arrangement, when liquid is spilled during use, it will pass through the gap between the two partitions 62 and fall onto the partition 63. The partition 63 can retain the liquid in the groove formed on the partition 63 through the side vanes 65 tilted upward on both sides, and will not continue to fall into the ventilation component 9, thereby preventing the ventilation component 9 from being damaged and at the same time not hindering the flow of air.

[0045] Optionally, in some embodiments, see Figure 3-Figure 5 The ventilation component 9 also includes a main duct 92, one end of which is fixedly connected to two air inlet channels 91, the main duct 92 and the air inlet channels 91 are internally connected, and one end of the air inlet channel 91 away from the main duct 92 is fixedly connected to two air inlets 93, and the air inlet ports 93 extend through the shell 96 to the interior.

[0046] The ventilation assembly 9 also includes an air outlet 95. Two connecting pipes 94 are fixedly connected to the outer end of the main pipe 92. The ends of the two connecting pipes 94 away from the main pipe 92 are fixedly connected to the air outlet 95. The outer end of the air outlet 95 is connected to a filtering system.

[0047] A motor 97 is fixedly installed inside the connecting pipe 94 , and a fan blade 98 is keyed to the output end of the motor 97 . The main pipe 92 , the connecting pipe 94 and the air outlet 95 are all fixedly connected to the bottom end of the desktop panel 8 .

[0048] The ventilation assembly 9 in this scheme is arranged below the grille assembly 6, which is also below the desktop panel 8. The shell 96 is fixedly connected to the outer frame 61, so that the air passing through the grille assembly 6 is sucked into the shell 96. The main duct 92, the connecting duct 94 and the air outlet 95 are all fixed to the bottom end of the desktop panel 8. Two air inlet channels 91 are fixed at one end of the main duct 92, and two air inlet ports 93 are fixed at the other end of the two air inlet channels 91. Thus, the four air inlet ports 93 are connected to the interior of the main duct 92 through the two air inlet channels 91. The four air inlet ports 93 all penetrate the shell 96 and extend to the interior thereof, that is, below the grille assembly 6. The outer end of the main duct 92 is fixed with two connecting ports. Pipe 94, the other ends of the two connecting pipes 94 are fixed with air outlets 95, a motor 97 is fixed inside each connecting pipe 94, and the output end of the motor 97 is fixed with fan blades 98. It is worth mentioning that the gas drawn into the air outlet 95 cannot be discharged directly to the outside, and it is necessary to connect a filtering system to the end of the air outlet 95. The filtering system is mainly composed of an activated carbon filter, a pre-filter element and a high-efficiency filter element. The activated carbon filter can effectively remove odors and volatile organic compounds by adsorbing organic compounds, odors and harmful gases in the gas. The pre-filter element is the first line of defense in the filtering system, which is used to capture large particles, while the high-efficiency filter element can filter fine particles.

[0049] By driving the fan blades 98 to rotate through the motor 97, the air in the main duct 92 can be drawn into the air outlet 95, and then the air in the shell 96 can be indirectly drawn to form a negative pressure inside. At this time, the air around the workbench 5 and the harmful gases generated during the experiment can be sucked into the shell 96 through the grille assembly 6, and the harmful gases, dust and steam in the air during the experiment can be effectively discharged, ensuring that the experimenters will not be exposed to high concentrations of chemicals for a long time, thereby protecting their health and safety. At the same time, the cleanliness and stability of the environment reduce the influence of interference factors, which is conducive to the accuracy of the experimental results.

[0050] Working principle: When the device is used for experiments, the operation experiment can be carried out on the workbench 5. A grid assembly 6 is arranged below the workbench 5. A plurality of partitions 1 62 and partitions 2 63 are respectively fixed at the upper and lower positions on the inner side of the outer frame 61. The positions of the partitions 1 62 and the partitions 2 63 are staggered. The gap between the two partitions 1 62 is just facing the partition 2 63 below. When liquid is spilled during the experiment, it will pass through the gap between the two partitions 1 62 and fall onto the partition 2 63, and will not continue to fall into the ventilation assembly 9, thereby preventing the ventilation assembly 9 from being damaged and at the same time not hindering the flow of air.

[0051] When harmful gases are generated during chemical experiments, the fan blades 98 are driven by the motor 97 to rotate and the air in the main duct 92 can be drawn into the air outlet 95, so that a negative pressure is formed inside the shell 96. At this time, the air around the workbench 5 and the harmful gases generated during the experiment can be sucked into the shell 96 through the grille assembly 6, ensuring that the experimenters will not be exposed to high concentrations of chemicals for a long time.

[0052] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
