Description

Technical Field

[0001] This utility model belongs to the technical field of automatic monitoring devices for electrophoresis apparatus, and in particular relates to an automatic monitoring device for an electrophoresis apparatus for protein detection. Background Technology

[0002] The core function of the automatic monitoring device of the electrophoresis apparatus is to monitor key parameters (such as temperature, current, and liquid circulation status) in real time through sensors, controllers, and feedback systems, and to automatically adjust or alarm according to preset conditions. Among them, liquid circulation status monitoring is usually achieved by physical contact sensing, that is, by sensing changes in liquid circulation status through direct contact between the pendulum needle and the contact block. Liquid circulation status monitoring can ensure a stable liquid circulation status during protein detection, thereby ensuring the uniformity of buffer temperature and concentration, improving protein separation effect, and ensuring the accuracy of protein detection.

[0003] For example, CN219641629U discloses an automatic monitoring device for an electrophoresis apparatus used for albumin detection. This device includes an electrophoresis tank, a mounting plate fixedly mounted on top of the tank, a water tank fixedly mounted on top of the mounting plate, a first conductive plate and a second conductive plate movably connected to the right side of the top of the mounting plate, a fixing block fixedly connected to the top left side of the first conductive plate, and an electric telescopic rod fixedly mounted on the right side of the top of the mounting plate. This automatic monitoring device, by setting up the first conductive plate, the second conductive plate, and a screw, rotates a knob on the right side of the second conductive plate, causing the screw to rotate. This causes the second conductive plate, threaded onto the screw surface, to move to the left within a square groove and approach the first conductive plate. This reduces the distance between the metal pendulum needle and the metal contact block, allowing for electrical contact with the contact block even during slight movements of the pendulum needle, thus facilitating accurate monitoring of the albumin detection electrophoresis apparatus.

[0004] The above-mentioned patent has the following defects in use:

[0005] The flow of electrophoresis solution drives the metal pendulum to deflect, forming a closed circuit with the metal contact block and triggering a normal signal. If the flow of solution is interrupted, the metal pendulum resets, the circuit breaks, and an alarm is triggered. The problem of the metal pendulum's swing amplitude being reduced and making it difficult to contact the metal contact block when the flow rate of electrophoresis solution is low can be improved by adjusting the positions of the metal pendulum and the metal contact block. However, in actual use, the flow velocity varies in different areas inside the electrophoresis tank, and monitoring from a single fixed position has significant limitations and cannot accurately reflect the overall monitoring effect inside the electrophoresis tank. Furthermore, when monitoring different areas, the weight of the metal pendulum itself will affect its swing amplitude when the flow rate of electrophoresis solution changes. With a fixed counterweight, the response speed of the metal pendulum slows down due to the influence of rotational inertia, resulting in insufficient sensitivity and affecting the accuracy of monitoring. Therefore, this utility model proposes an automatic monitoring device for an electrophoresis apparatus for protein detection. Utility Model Content

[0006] This invention provides an automatic monitoring device for an electrophoresis apparatus used for protein detection. Through a counterweight adjustment mechanism, the position and weight of the hollow metal pendulum needle can be adjusted in real time when the electrophoresis solution flow rate changes. This not only improves the problem of reduced pendulum amplitude and difficulty in contacting the metal contact block when the electrophoresis solution flow rate is low, reducing false alarms, but also improves the deflection response speed of the hollow metal pendulum needle when the electrophoresis solution flow rate changes, thus increasing sensitivity. Furthermore, the movable monitoring mechanism can drive a pair of hollow metal pendulum needles and the metal contact block to perform multiple monitoring points inside the electrophoresis tank, reducing blind spots and improving monitoring accuracy. In summary, this invention solves the problems in the prior art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0034] Please see Figures 1-5 As shown, the present invention provides an automatic monitoring device for an electrophoresis apparatus for protein detection, comprising:

[0035] The electrophoresis tank 1 and the cover plate 2 are connected to the electrophoresis tank 1 by hexagonal bolts. Water pipes 3 are fixedly connected to both sides of the electrophoresis tank 1. A pair of through grooves 14 are cut at the top of the cover plate 2. Two pairs of conductive plates 5 are provided inside the electrophoresis tank 1. The tops of the two pairs of conductive plates 5 pass through the through grooves 14 and extend to their tops. T-shaped fixing plates 6 are fixedly connected to the tops of the two pairs of conductive plates 5. An alarm device 7 is fixedly connected between the tops of the pair of T-shaped fixing plates 6. Connecting wires 8 are fixedly connected between the two sides of the alarm device 7 and the tops of the pair of conductive plates 5.

[0036] A pair of counterweight adjustment mechanisms 9 are provided between a pair of conductive plates 5, and the counterweight adjustment mechanisms 9 are used to adjust the distance and weight according to the change of flow rate.

[0037] The mobile monitoring mechanism 11 is located on the top of the cover plate 2 and is used to drive the two pairs of conductive plates 5 to move laterally.

[0038] The counterweight adjustment mechanism 9 includes a hollow metal pendulum needle 901. The top of the hollow metal pendulum needle 901 is provided with a pointer sealing plate 902 in contact with it, and the bottom end of the pointer sealing plate 902 is fixedly connected to a sealing plug 903. The outer wall of the sealing plug 903 is in close contact with the inner wall of the hollow metal pendulum needle 901. Multiple cylindrical grooves are carved on the sealing plug 903, and counterweight bars 904 that are in close contact with the inner wall of the cylindrical grooves are inserted inside. The bottom ends of the multiple counterweight bars 904 are in contact with the inner bottom end of the hollow metal pendulum needle 901. A metal contact block 10 is fixedly connected to one side of the conductive plate 5 located on one side, and the metal contact block 10 is located on one side of the hollow metal pendulum needle 901.

[0039] In the specific implementation process, a pair of water pipes 3 can be connected to an external water pump circulation device to drive and maintain the circulation of buffer solution in the electrophoresis tank. During the flow of buffer solution in the electrophoresis tank, the hollow metal pendulum needle 901 is pushed to deflect and contact the metal contact block 10. At the same time, the alarm device 7 is connected to a pair of conductive plates 5 through a pair of connecting wires 8, forming an electrical closed loop between the alarm device 7, the pair of connecting wires 8, the pair of conductive plates 5, the metal contact block 10, and the hollow metal pendulum needle 901. When the alarm device 7 detects a continuous current signal, it determines that the liquid flow is normal and does not trigger an alarm. However, when the flow of buffer solution in the electrophoresis tank stops, the hollow metal pendulum needle 901 does not contact the metal contact block 10, the circuit is broken, the alarm device 7 detects the current interruption, and triggers an alarm. During the monitoring process, the pair of hollow metal pendulum needles 901 and the metal contact block 10 are in the electrophoresis tank. 1. When multiple monitoring points are located inside, the flow rates in different areas are different. When the flow rate decreases, the pointer sealing plate 902 and the sealing plug 903 are pulled apart from the hollow metal pendulum needle 901, and part of the counterweight bar 904 on the sealing plug 903 is removed. Then, the pointer sealing plate 902 and the sealing plug 903 are driven to insert and seal with the hollow metal pendulum needle 901. By reducing the number of counterweight bars 904, the weight of the hollow metal pendulum needle 901 is adjusted so as to improve the influence of the rotational inertia of the hollow metal pendulum needle 901 at low flow rates when the flow rate of the electrophoresis liquid is low, improve its deflection response speed and sensitivity at low flow rates, and reduce hysteresis. In this scheme, the cover plate 2 is connected to the electrophoresis tank 1 by hexagonal bolts. Multiple bolt through holes are drilled on the cover plate 2, and bolt grooves are drilled at the top of the electrophoresis tank 1. The operator rotates the hexagonal bolts through the bolt through holes and into the bolt grooves for connection.

[0040] Among them, a control valve 4 is fixedly connected to the outer wall of each pair of water pipes 3.

[0041] The water pipe 3 can be opened or closed by controlling valve 4, which is convenient for staff to use.

[0042] Among them, the bottom ends of the two T-shaped fixing plates 6 on the outer side are fixedly connected to the slide cylinder 907, and the output end of the slide cylinder 907 is fixedly connected to the connecting long block 906. The connecting long block 906 is rotatably connected to the rotating rod 905 through the bearing, and the rotating rod 905 is sleeved on the outer wall of the hollow metal oscillating needle 901.

[0043] The slide cylinder 907 drives the connecting block 906 to move, which in turn drives the hollow metal pendulum needle 901 to move closer to the metal contact block 10 via the rotating rod 905. This adjusts the distance between the two to improve the problem that the hollow metal pendulum needle 901 has a reduced swing amplitude and is difficult to contact the metal contact block 10 when the electrophoretic liquid flow rate is low, thereby reducing false alarms.

[0044] Among them, a plurality of built-in rods 908 are fixedly connected between opposite sides of a pair of conductive plates 5, and a connecting long block 906 is sleeved on the outer wall of the plurality of built-in rods 908.

[0045] By setting the built-in rod 908, the connecting block 906 moves along its outer wall, keeping the connecting block 906 in linear motion and preventing positional deviation.

[0046] The bottom end of the hollow metal oscillating needle 901 is located at the bottom of the conductive plate 5, and the metal contact block 10 is inclined on the side near the hollow metal oscillating needle 901.

[0047] The bottom end of the hollow metal pendulum 901 is located at the bottom of the conductive plate 5 so that the hollow metal pendulum 901 can be deflected when the electrophoretic liquid flows. The side of the metal contact block 10 near the hollow metal pendulum 901 is inclined so that it can easily contact the hollow metal pendulum 901 when it is deflected and tilted, and increase the contact area. Specific Implementation Example 2:

[0049] Please see Figure 1 and Figure 5 As shown, in a preferred embodiment, the mobile monitoring mechanism 11 includes a servo motor 1101, a pair of side plates 1104 are fixedly connected to the top of the cover plate 2, and the servo motor 1101 is fixedly connected to one side plate 1104. A threaded rod 1102 is rotatably connected between the opposite sides of the pair of side plates 1104 through a bearing, and one end of the threaded rod 1102 is fixedly connected to the output end of the servo motor 1101. A threaded moving block 1103 is threadedly connected to the outer wall of the threaded rod 1102, and a pair of electric telescopic rods 12 are fixedly connected to the top of the threaded moving block 1103. A connecting straight plate 13 is fixedly connected between the opposite sides of the two T-shaped fixing plates 6 located on the inner side, and the bottom end of the connecting straight plate 13 is fixedly connected to the top end of the pair of electric telescopic rods 12.

[0050] In the specific implementation process, the drive servo motor 1101 drives the threaded rod 1102 to rotate, which in turn drives the threaded moving block 1103 to move. The threaded moving block 1103 drives the two pairs of T-shaped fixing plates 6, a pair of alarm devices 7 and two pairs of conductive plates 5 on both sides to move along the conductive groove 14 through the electric telescopic rod 12 and the connecting straight plate 13. This causes the pair of hollow metal pendulum needles 901 and metal contact blocks 10 to move inside the electrophoresis tank 1, adjust their positions, realize multiple monitoring points, reduce monitoring blind spots and improve monitoring accuracy.

[0051] The threaded moving block 1103 has a threaded through hole drilled on its outer wall, and the threaded moving block 1103 is sleeved on the outer wall of the threaded rod 1102 through the threaded through hole and is threadedly connected to it.

[0052] By setting a threaded through hole, the threaded moving block 1103 and the threaded rod 1102 are threadedly connected, so that the threaded moving block 1103 can be moved when the threaded rod 1102 rotates.

[0053] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0054] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0055] The working principle of this utility model is as follows:

[0056] In use, this invention first activates a pair of external water pumps connected to the water pipes 3 and opens the control valve 4 to circulate the buffer solution in the electrophoresis tank. Simultaneously, the hollow metal pendulum needle 901 deflects under the influence of the flowing buffer solution, contacting the metal contact block 10. At the same time, the alarm device 7 is connected to a pair of conductive plates 5 via a pair of connecting wires 8, forming a closed electrical circuit between the alarm device 7, the connecting wires 8, the conductive plates 5, the metal contact block 10, and the hollow metal pendulum needle 901. The alarm device 7 detects a continuous current signal, determines that the liquid flow is normal, and does not trigger an alarm. After monitoring of that area is completed, the servo motor 1101 drives the threaded rod 1102 to rotate, causing it to move the threaded moving block 1103. The threaded moving block 1103, via the electric telescopic rod 12 and the connecting straight plate 13, moves the two pairs of T-shaped fixing plates 6, the alarm device 7, and the two pairs of conductive plates 5 along the conductive groove 14, causing the hollow metal pendulum needle 901 and the metal contact block 10 to move within the electrophoresis tank. The internal components of body 1 are moved to a monitoring location. During monitoring, the flow rate varies in different areas. When the flow rate decreases, the pointer sealing plate 902 and sealing plug 903 are pulled apart from the hollow metal pendulum needle 901, and part of the counterweight bar 904 on the sealing plug 903 is removed. Then, the pointer sealing plate 902 and sealing plug 903 are driven to engage and seal with the hollow metal pendulum needle 901. The weight of the hollow metal pendulum needle 901 is adjusted by reducing the number of counterweight bars 904. Immediately afterwards, the slide cylinder 907 drives the connecting block 906. The device is moved so that the hollow metal pendulum needle 901 is moved closer to the metal contact block 10 via the rotating rod 905. The distance between the two is adjusted to improve the problem that the swing amplitude of the hollow metal pendulum needle 901 is reduced and it is difficult to contact the metal contact block 10 at low flow rates. At the same time, the deflection response speed and sensitivity of the hollow metal pendulum needle 901 at low flow rates are improved. After the buffer solution flow in the electrophoresis tank stops, the hollow metal pendulum needle 901 does not contact the metal contact block 10, the circuit is broken, the alarm device 7 detects the current interruption and alarms.
