Description

Technical Field

[0001] The invention relates to the field of biological laboratory equipment, in particular to an extraction operating table for biological experiments. Background Art

[0002] The biological experiment workbench, also known as the biological safety cabinet or laboratory fume hood, is a commonly used experimental equipment in modern laboratories. This equipment is generally used to carry out various biological experimental operations, such as cell culture, microbiology research, drug preparation, etc.

[0003] The existing biological experiment operating tables have the following main defects: first, the existing experimental operating tables are mostly open, and the open design will make the experimental process completely exposed. Although this is convenient to operate, the external environment will affect the experimental results, especially in some biological experiments, microorganisms have relatively high requirements for temperature and environment, which can easily cause contamination to experimental samples; second, the existing equipment is mostly an integral structure, which is not convenient to disassemble and assemble during transportation and transfer; third, in the existing experimental process, extraction and addition of reagents are generally performed manually, especially in comparative experiments, the process of manual addition and extraction of reagents cannot ensure synchronous quantitative addition and extraction, which will make the experimental effect unsatisfactory; fourth, during the experiment, it is generally necessary to shake the reaction tube or glass bottle to speed up the reaction so as to observe the experimental results more intuitively, but the existing ones are manually shaken, which will pose a safety hazard, and the frequency and amplitude of the shaking will also affect the experimental results. Summary of the invention

[0004] In order to solve the above defects, the present invention adopts the following technical solutions: The invention discloses an extraction operation table for biological experiments, comprising a frame, a mounting base, a disassembly cover, a constant temperature operation table, a cleaning pool, a test tube cabinet, a tool cabinet, an extraction mechanism, a vibration-lifting mechanism and a controller. The mounting base is fixedly arranged on the upper part of the frame, and mounting grooves are arranged on both sides of the mounting base. Cards are also fixed on both sides of the bottom of the disassembly cover, and the card is installed in cooperation with the mounting grooves. An operation window is also movably installed at the front end of the disassembly cover, and an operation space is formed between the disassembly cover and the mounting base. The constant temperature operation table, the test tube cabinet and the tool cabinet are respectively arranged on the mounting base. A cleaning pool and a through hole are also arranged on the mounting base, and the through hole is communicated with the inside of the frame to form a storage cavity. The vibration-lifting mechanism is arranged in the storage cavity, and the extraction mechanism is fixedly installed inside the disassembly cover. The controller is installed at the external front end of the disassembly cover, and the controller is respectively connected with the extraction mechanism and the vibration-lifting mechanism by signal.

[0005] Through the above technical scheme, the operating table can be quickly assembled, replacing the existing experimental operating table that is processed as a whole and occupies a large space or is inconvenient to transport during transportation. The disassembly cover, the installation base plate and the frame can be directly disassembled during transportation, and the liquid in the test tube or other bottle can be quantitatively extracted through the extraction mechanism during the experiment, replacing the traditional process of manual extraction or addition of reagents by experimenters, which will not cause experimental errors and ensure that the experimental process is more accurate. Secondly, the vibration mechanism can automatically oscillate the test tube or other glass bottle in some experimental processes that require shaking, replacing the traditional manual hand-held shaking process, reducing the overflow of reaction liquid and causing safety hazards such as burns.

[0006] Preferably, sealing silicone is fixedly provided on the edges where the mounting groove contacts the inner wall at the bottom of the disassembly cover, threaded holes are provided in the mounting grooves, and a positioning circular hole is also provided at the rear end of the card plate, and the axis of the threaded hole and the positioning circular hole are on the same straight line.

[0007] Through the above technical solution, during the assembly process, the card plates on both sides of the bottom of the disassembly cover are extended into the corresponding installation grooves, and then the positioning circular holes and the threaded holes are aligned, and then the card plates are fixed in the installation grooves by hexagonal screws or other screws. The disassembly process is the opposite, and the gap is sealed by sealing silicone, which increases the sealing effect while ensuring that the disassembly cover does not shake.

[0008] Preferably, an annular liquid return groove is also provided on the installation base plate, a porous filter plate is fixedly arranged at the upper part of the annular liquid return groove and the level of the installation base plate, the bottom of the annular liquid return groove is also connected to the waste liquid collection bucket through a pipeline, the waste liquid collection bucket is fixedly installed inside the frame and is located on one side of the storage cavity, and a serpentine distribution coil is also arranged inside the constant temperature operating table, and both ends of the coil are respectively connected to the heat exchanger to form a closed loop, and the heat exchanger is installed inside the frame and is connected to the controller signal.

[0009] Through the above technical solution, the annular liquid return tank can collect the reaction liquid spilled during the experiment and store it separately through the waste liquid collection barrel. Secondly, the temperature of the liquid in the heat exchanger can be controlled by the controller, so that the heat exchanger can maintain a constant temperature or stable temperature of the constant temperature operating table through the coil, ensuring the temperature requirements of cell tissues or microbial reactions during biological experiments, replacing the traditional method of temperature control through air, directly acting on the constant temperature operating table, improving experimental efficiency, and making temperature control more accurate and effective.

[0010] Preferably, side windows are provided on both sides of the disassembly cover, transparent glass is provided in the side windows and the operating window, and a handle is provided at the bottom of the front end of the operating window, one side of the disassembly cover is also fixedly connected to the air intake pipe, the other end of the air intake pipe extends into the disassembly cover and is connected to the air purifier, the air purifier is fixedly mounted on the top plate, the top plate is fixedly mounted inside the disassembly cover, and the top plate is parallel to the top surface of the disassembly cover, a plurality of air inlets are also provided on the top plate, filters are provided in the air inlets, a plurality of lamps are also fixedly mounted on the bottom surface of the top plate, and the top plate is located above the extraction mechanism.

[0011] Through the above technical solution, the side windows not only reduce the weight of the disassembly hood, but also enable the internal experimental process to be observed through the transparent glass. The air intake pipe is directly connected to the air supply system, and the air is purified through the air purifier to prevent untreated air from directly entering during the experiment. The filter net can adsorb and filter harmful substances such as exhaust gas generated during the experiment during the return air process, thereby preventing harmful gases generated during the experiment from entering the atmosphere.

[0012] Preferably, the extraction mechanism includes a track, a track self-propelled device, a screw, an extraction controller, a positioning probe, a first motor, a first electric cylinder, an extraction seat, an electric suction pump, a solenoid valve, a suction tube and an extractor. The track is symmetrically installed on the front and rear inner walls of the disassembly cover. The track self-propelled devices are movably installed on the track, and the two track self-propelled devices are fixedly connected by two vertically arranged screws. The extraction controller is movably installed between the two screws, and the first motor is also fixedly arranged on the top of the extraction controller. The first electric cylinder is also movably arranged in the middle of the extraction controller. The output end of the first motor is fixedly connected to the base of the first electric cylinder, and the extraction seat is fixed to the telescopic end of the first electric cylinder. A number of extractors are arranged on the extraction seat, and a number of electric suction pumps are also arranged on the extraction seat. Each electric suction pump is connected to the corresponding extractor through a suction tube. A solenoid valve is also arranged on the suction tube. The track self-propelled device, the extraction controller, the positioning probe, the first motor, the first electric cylinder, the electric suction pump and the solenoid valve are all connected to the controller signal.

[0013] The above technical solution replaces the traditional manual extraction or reagent addition process, in which the extraction or addition dosage cannot be accurately controlled manually. Through the extraction mechanism, when a specified dosage of reagent needs to be added, the actual dosage only needs to be input into the controller through the control screen. The controller will drive the track self-propelled device to the specified position, and then the extraction controller will move to the top of the instrument. Then the controller will drive the first electric cylinder to move downward so that the extractor extends into instruments such as test tubes. Then the electric suction pump adjusts the stroke according to the dosage and absorbs the reagent into the extractor. This process can accurately control the dosage, and in the comparative experiment process, the addition timing can be synchronously controlled. Compared with the traditional comparative experiment process, the extraction mechanism avoids experimental errors caused by asynchronous addition or unequal addition dosage.

[0014] Preferably, a water pipe is fixedly arranged on one side of the cleaning pool, the other end of the water pipe is connected to a water pump, the water pump is fixedly installed inside the frame, the bottom of the cleaning pool is also connected to the filter through a collecting pipe, guide rails are also arranged on both sides of the upper edge of the through hole, and a cover plate is slidably installed between the guide rails.

[0015] Through the above technical solution, the experimental equipment can be cleaned after the experiment is completed. The liquid generated during the cleaning process is filtered through a filter to prevent it from being directly discharged into the sewer pipe and causing pollution. When there is no need to shake to speed up the reaction process, the vibration mechanism is located in the storage cavity, and the cover plate can prevent impurities and other substances from entering. When necessary, it can be directly controlled to extend, and then the test tube and other bottles are placed on the vibration mechanism, and shaken to accelerate the reaction process. There is no need to take out the test tube separately, etc., thus avoiding cross contamination of air or environment.

[0016] Preferably, the vibration mechanism includes an oscillation component and an extraction component, the extraction component is movably installed on the top of the oscillation component, the oscillation component includes a lifting cylinder, a box, a second motor, a reducer, a support rod, a rotating shaft, a rotating disk, a protrusion, a push rod, a roller, a box cover, a spring and an oscillation plate, the lifting cylinder is fixed at the bottom of the storage cavity, the telescopic end of the lifting cylinder is fixedly connected to the bottom of the box, the reducer is fixed inside the box, one side of the reducer is connected to the second motor, the output end of the reducer is connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the rotating disk, a plurality of support rods are also installed in the box, the top of each support rod is in sliding contact with the bottom surface of the rotating disk, the upper end surface of the rotating disk is also provided with a plurality of protrusions in a circumferential array, a box cover is also provided on the box, a plurality of push rods are provided on the circumference of the bottom of the oscillation plate, the bottom of the push rods are fixedly provided with rollers, and the push rods all pass through the box cover, the outside of the push rod is also wrapped with a spring, the spring is located between the box cover and the oscillation plate, and the two ends of the spring are respectively fixedly connected to the box cover and the oscillation plate.

[0017] Through the above technical solution, the oscillation component mainly generates oscillation. When shaking is required, the test tube or bottle only needs to be fixed on the extraction component, and then the controller is started, and the second motor drives the reducer to rotate, so that the rotating disk rotates. During the rotation of the rotating disk, the protrusion also rotates. When the protrusion contacts the roller, the push rod will move up. When the protrusion is separated from the roller, the push rod moves down. In this way, the push rod will drive the oscillation plate to reciprocate up and down, and the spring mainly plays a return role, thereby producing an oscillation effect.

[0018] Preferably, the leaching component comprises a disc, a fastening component, a support column, a top cover, a connecting component, a movable plate, a limiting rod, a straight notch, an upper connecting block, a lower connecting block, a connecting column, a movable splint, a support seat and a protective pad. The disc is movably installed in the middle of the upper part of the oscillation plate, and the fastening component is symmetrically arranged on the oscillation plate, the bottom of the support column is fixedly connected to the disc, the top cover is fixed on the top of the support column, the four bottom corners of the top cover are fixed with the connecting component, the movable plate is movably installed between each adjacent connecting component, limiting rods are fixedly arranged on both sides of the movable plate, a straight notch is provided on the movable plate, and an upper connecting block and a lower connecting block are fixedly arranged above and below the straight notch, a connecting column is fixed between the upper connecting block and the lower connecting block, a movable splint is movably installed on the connecting column, a clamping opening is provided at the front end of the movable splint, one end of the movable splint extends into the straight notch, the support seat is fixedly installed on the movable plate and is located below the lower connecting block, and a protective pad is also arranged on the support seat.

[0019] Through the above technical solution, the disc can rotate on the oscillation plate, which makes it easy to adjust the installation surface when installing the test tube or bottle. First, place the bottom of the test tube or bottle on the protective pad on the support seat, and then manually adjust the position of the movable splint. The adjustment process is mainly to fix the test tube or bottle to prevent it from detaching from the extraction component during oscillation.

[0020] Preferably, the fastening assembly includes an arc-shaped clamping block, a fixing seat and a fastening screw, the fixing seat is fixed on the oscillation plate, the fastening screw is movably installed on the fixing seat, one end of the fastening screw is movably connected to the arc-shaped clamping block, the inner side of the arc-shaped clamping block is opposite to the outer edge of the disc, when the test tube or the bottle is installed, the fastening assembly is not locked, which is convenient for rotating the test tube to different working surfaces, and after installation, whether to lock the disc can be manually controlled as needed, the connecting assembly includes a first connecting plate, a second connecting plate and an arc-shaped slide groove, the first connecting plate and the second connecting plate are fixedly connected and are located below the top cover, and the angle between the first connecting plate and the second connecting plate is 90 degrees.

[0021] Preferably, an adjustment block is fixedly arranged on the inner side of the movable plate, an adjustment spring is fixedly arranged on the adjustment block, the top of the adjustment spring is fixedly connected to one end of the movable clamping plate extending into the straight slot, and an elastic protective ring is also arranged in the clamping mouth.

[0022] The beneficial effects of the present invention are: 1. The installation groove on the installation base plate makes it easy to disassemble and assemble the disassembly cover, which is beneficial to the transportation and transfer of the operating table. Secondly, the controller can perform real-time temperature control and adjustment on the constant temperature operating table, ensuring that the experiment will not be affected by the temperature. In addition, the present application can separately collect and treat the cleaning wastewater and chemical waste liquid generated during the experiment, avoiding pollution caused by direct removal.

[0023] 2. Through the extraction mechanism, it is possible to quantitatively extract or add reagents to test tubes or other bottles. Especially in the comparative experiment, under the control of the controller, each electric suction pump can synchronously add or absorb reagents quantitatively, replacing the traditional manual addition that causes each reaction tube to be unable to synchronously add reagents quantitatively, resulting in inaccurate experimental results. The dripping speed and dosage can also be synchronously controlled during addition.

[0024] 3. The vibration mechanism can replace the traditional manual shaking to speed up the reaction process. Manual shaking can easily cause glass bottles such as test tubes to fall during the shaking process, and the reaction reagents will splash during the process, causing safety hazards. Secondly, manual shaking cannot ensure a constant oscillation frequency. The vibration effect is caused by the separation and contact of the protrusion and the ejector rod. The frequency of the vibration can be controlled by the speed of the first motor, which ensures that the shaking frequency remains constant at all times, ensuring that the reaction is accelerated while not causing a large deviation in the reaction effect.

[0034] Extraction and addition process: Before the experiment, the experimenter adds the corresponding reagents into the test tube and arranges them on the test tube carrier. During the experiment, generally in a closed environment, the controller 10 performs automatic extraction. First, the controller 10 automatically identifies and locates the position of the test tube to be extracted according to the feedback information of the positioning probe 804. Then the track self-propelled device 801 starts and moves along the track 800 to the top of the test tube. Then the extraction controller 803 moves horizontally along the lead screw 802. The purpose of the horizontal movement is to further determine the position. Then the first electric cylinder 806 moves downward so that the bottom of the extractor 811 extends into the test tube. This process can extract multiple test tubes at the same time. During extraction, the solenoid valve 809 is opened, and then the liquid in the test tube is synchronously and quantitatively sucked in under the action of the electric suction pump 808, thereby realizing the extraction of reagents. When adding reagents, it is just the opposite of the extraction process. Different reagents or the same reagents can be quantitatively and synchronously added to the test tube. This process replaces manual extraction and addition, which not only saves time, but also makes the operation process more precise.

The oscillation component 91 includes a lifting cylinder 910, a box 911, a second motor 912, a reducer 913, a support rod 914, a rotating shaft 915, a rotating disk 916, a bump 917, a push rod 918, a roller 919, a box cover 9190, a spring 9191 and an oscillation plate 9192. The lifting cylinder 910 is fixed to the bottom of the storage cavity 15. The telescopic end of the lifting cylinder 910 is fixedly connected to the bottom of the box 911. The reducer 913 is fixed inside the box 911. One side of the reducer 913 is connected to the second motor 912. The output end of the reducer 913 is connected to the rotating shaft 915. The top of the rotating shaft 915 is fixedly connected to the rotating disk 916, and a plurality of support rods 914 are also installed in the box body 911. The top of each support rod 914 is in sliding contact with the bottom surface of the rotating disk 916. The upper end surface of the rotating disk 916 also has a plurality of protrusions 917 in a circumferential array. A box cover 9190 is also provided on the box body 911, and a plurality of top rods 918 are provided on the bottom circumference of the oscillation plate 9192. Rollers 919 are fixedly provided at the bottom of the top rods 918, and the top rods 918 all pass through the box cover 9190. A spring 9191 is also wrapped outside the top rod 918, and the spring 9191 is located between the box cover 9190 and the oscillation plate 9192, and the two ends of the spring 9191 are respectively fixedly connected to the box cover 9190 and the oscillation plate 9192.

[0037] The oscillation component 91 mainly generates oscillation, and the leaching component 92 mainly carries the test tube, and the leaching component 92 can rotate on the oscillation component 91, that is, during the experiment, the test tube or conical bottle containing the reaction liquid can rotate during the up and down oscillation process. When shaking and rotating are required, just fix the test tube or bottle body on the leaching component 92, and then start the controller 10, and the second motor 912 drives the reducer 913 to rotate, so that the rotating disk 916 rotates. During the rotation of the rotating disk 916, the protrusion 917 also rotates. When the protrusion 917 is in contact with the rotating disk 916, the protrusion 917 rotates. After the roller 919 makes contact, the push rod 918 will move up. When the protrusion 917 moves away from the roller 919, that is, the contact is released, the push rod 918 moves down. In this way, the push rod 918 will drive the oscillation plate 9192 to reciprocate up and down. When oscillating up and down, due to the vibration generated, the leaching component 92 will also rotate on the oscillation plate 9192, among which the spring 9191 mainly plays a returning role. The leaching component 92 is movably arranged on the oscillation plate 9192, and it is also convenient to carry test tubes or other tools. It only needs to be rotated as a whole to carry them to different working surfaces of the leaching component 92.

[0038] The extraction component 92 includes a disc 920, a fastening component 921, a support column 922, a top cover 923, a connecting component 924, a movable plate 925, a limiting rod 926, a straight notch 927, an upper connecting block 928, a lower connecting block 929, a connecting column 9290, a movable splint 9291, a supporting seat 9292 and a protective pad 9293. The disc 920 is movably installed in the middle of the upper part of the oscillation plate 9192, and the fastening components 921 are symmetrically arranged on the oscillation plate 9192. The fastening components 921 are mainly the key to whether the disc 920 can rotate. When it does not need to rotate, it can be locked so that the disc 920 will not rotate on the oscillation plate 9192. The bottom of the supporting column 922 is fixedly connected to the disc 920, and the top cover 923 is fixed on the top of the supporting column 922. The four corners of the bottom of the top cover 923 are fixed with the connecting component Part 924, a movable plate 925 is movably installed between each adjacent connecting component 924, and limit rods 926 are fixedly set on both sides of the movable plate 925.

[0039] Carrying test tubes or other bottles: Before the lifting and vibrating operation, the extraction and addition operations are completed by the extraction mechanism 8. The extraction mechanism 8 and the lifting and vibrating mechanism 9 can work independently or cooperate with each other. When oscillation is required, firstly, the bottom of the test tube or conical flask is brought into contact with the protective pad 9293 on the support seat 9292. Here, the conical flask is taken as an example. Then, the bottleneck of the conical flask is inserted into the clamping port 39. During this process, the movable splint 9291 can be moved up and down at any time according to the diameter of the bottleneck, so that the movable splint 9291 can clamp the bottleneck. The movable plate 925 can adjust the angle between two adjacent connecting components 924, that is, slide in the arc-shaped slide groove 9242 through the limit rod 926, so that the movable plate 925 can be adjusted. The bottle on 25 can maintain different positions, which can be vertical or inclined. After the oscillation is completed, reagents are generally added to the inside of the bottle during the extraction process. When the reagents are extracted, the state of the bottle needs to be adjusted. If the entire bottle is taken out for extraction, the liquid will become turbid during the movement. Secondly, when the reaction reagent is added again, it will also cause turbidity if it is added vertically. Therefore, when the extraction is performed after the oscillation is completed, the bottle is generally slowly adjusted to tilt the bottle at a certain angle. This ensures that the added liquid can flow in along the inner wall, and will not splash the internal liquid like in the vertical state, causing the liquid inside the bottle to become turbid.

[0040] The fastening assembly 921 includes an arc-shaped clamping block 9210, a fixing seat 9211 and a fastening screw 9212. The fixing seat 9211 is fixed on the oscillation plate 9192. The fastening screw 9212 is movably installed on the fixing seat 9211. One end of the fastening screw 9212 is movably connected to the arc-shaped clamping block 9210. The inner side of the arc-shaped clamping block 9210 is opposite to the outer edge of the disk 920. The fastening assembly 921 can be used to control whether the disk 920 can be rotated during the oscillation process. The connecting assembly 924 includes a first connecting plate 9240, a second connecting plate 9241 and an arc-shaped slide groove 9242. The first connecting plate 9240 and the second connecting plate 9241 are fixedly connected and are located below the top cover 923. The angle between the first connecting plate 9240 and the second connecting plate 9241 is 90 degrees.

[0041] An adjusting fixed block 40 is also fixedly provided on the inner side of the movable plate 925, and an adjusting spring 41 is fixedly provided on the adjusting fixed block 40. The top of the adjusting spring 41 is fixedly connected to one end of a movable clamping plate 9291 extending into the straight slot 927. Before clamping the bottle body, the clamping port 39 is generally aligned with a suitable bottleneck according to the position. This process generally causes the movable clamping plate 9291 to move along the connecting column 9290, which tightens the adjusting spring 41. When the bottleneck is located in the clamping port 39, the movable clamping plate 9291 is generally moved downward under the action of the adjusting spring 41. This process ensures the stability of the bottle body and prevents it from shaking. An elastic protective ring 42 is also provided in the clamping port 39, and the elastic protective ring 42 is mainly used to protect the bottle body.
