[0001] This invention relates to the field of water bath technology, and in particular to a synchronous sample feeding device for parallel experiments in a constant temperature water bath. Background Technology

[0017] This invention provides a synchronous sample addition device for parallel experiments in a constant temperature water bath. The frame can be erected above the water bath, and a leveling mechanism can be used to level the movable plate, ensuring the sample addition box is horizontal. After leveling, the position of the water bath can be moved so that different sample addition tubes are aligned with the filling ports of the water baths used for parallel experiments. The materials required for the parallel experiments can then be added to the sample addition box through the filling cylinder. At this time, the piston block in the sample addition box is in a state of blocking the feed port. When it is necessary to add materials to different water baths simultaneously, the position can be adjusted using an adjusting mechanism. The position of the stopper block exposes the feed inlet, allowing the material in the sample box to be guided into the enclosure through the feed inlet and then added to the water bath through the sample tube. This effectively enables simultaneous feeding into different water baths. Since the sample box is horizontal, the material flow rate into different feed inlets remains consistent, resulting in more accurate comparative experimental results. The further the piston block moves downward, the greater the material flow rate, allowing for flexible control of the feeding rate. Additionally, the sealing mechanism can partially block the feed inlets, enabling flexible control of the number of control groups in parallel experiments, leading to better performance.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1-9 As shown in the figure, a synchronous sample addition device for parallel testing in a constant temperature water bath according to an embodiment of the present invention includes a frame 101 and a movable plate 104. A support plate 102 is fixedly disposed at the bottom end of the frame 101, and a support leg 103 is fixedly disposed on the lower surface of the support plate 102. An installation opening is provided on the outer wall of the movable plate 104, and a sample addition box 105 is movably disposed in the installation opening. A sample addition tube 108 is connected to the lower surface of the sample addition box 105. The sample addition box 105 and the movable plate 104 are connected by a sampling tube 108. The sample box 105 is fixedly connected by a fixing component. A feeding cylinder 106 is connected to the upper surface of the sample box 105. A guide port 109 is provided at equal intervals on one outer wall of the sample box 105. A retaining wall 107 is also provided at equal intervals and corresponding to the guide ports 109, with the retaining wall 107 located outside the guide ports 109. A piston block 110 is movably installed in the sample box 105, and the upper surface of the piston block 110 is inclined towards the guide port 109. The sample box 105 also includes:

[0030] A leveling mechanism, located in frame 101, is used to adjust the movable plate 104 to maintain its horizontal position.

[0031] A blocking mechanism is installed in the enclosure 107 to block the material guide port 109;

[0032] The adjustment mechanism is located on one side of the sample dispensing box 105 and is used to adjust the synchronous sample dispensing rate.

[0033] The frame 101 can be erected above the water bath. The movable plate 104 can then be leveled using a leveling mechanism to ensure the sample loading box 105 is horizontal. After leveling, the position of the water bath can be moved so that the different sample loading tubes 108 are aligned with the feeding ports of the water baths used for parallel experiments. Then, the materials required for the parallel experiments can be added to the sample loading box 105 through the feeding cylinder 106. At this time, the piston block 110 in the sample loading box 105 is in a state of blocking the guide port 109. When materials need to be added to different water baths simultaneously, the position of the piston block 110 can be adjusted using an adjusting mechanism to allow the guide port to be level. With the sample inlet 109 exposed, the material in the sample box 105 can be guided into the enclosure 107 through the feed inlet 109, and then added to the water bath through the sample tube 108. This effectively enables synchronous feeding of different water baths. Since the sample box 105 is in a horizontal state, the material flow rate entering different feed inlets 109 remains consistent, making the comparative experiment results more accurate. The more the piston block 110 moves down, the greater the material flow rate, allowing for flexible control of the sample feeding rate. At the same time, the sealing mechanism can also block part of the feed inlets 109, allowing for flexible control of the number of control groups in parallel experiments, resulting in better performance.

[0034] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 The leveling mechanism includes a fixed frame 201 fixedly installed in the frame 101. Mounting holes are provided at the four corners of the outer wall of the fixed frame 201, and a first cylinder 202 is rotatably installed in each mounting hole. Fixed holes are also provided at the four corners of the outer wall of the movable plate 104, and a second cylinder 204 is rotatably installed in each fixing hole. A telescopic member 203 is rotatably connected to the lower surface of the first cylinder 202. The specific structure of the telescopic member 203 is not limited. In this embodiment, preferably, the telescopic member 203 is a hydraulic cylinder, and the telescopic end of the telescopic member 203 is rotatably connected to the upper surface of the second cylinder 204. A detection unit is also provided above the fixed frame 201 to detect the levelness of the movable plate 104. Since both the first cylinder 202 and the second cylinder 204 can rotate flexibly, the distance between the first cylinder 202 and the second cylinder 204 can be flexibly adjusted by extending and retracting the telescopic member 203. By using multiple sets of telescopic members 203 together, the movable plate 104 can be adjusted to a horizontal state, making it very convenient to use.

[0035] As one embodiment of the present invention, please refer to Figure 1 and Figure 8The detection unit includes a universal ball 205. A circular groove is formed on the upper surface of the frame 101, and the universal ball 205 is rotatably positioned in the groove. A connecting rod 206 is fixedly mounted on the outer wall of the universal ball 205, and a counterweight 209 is provided at the end of the connecting rod 206. A through hole communicating with the circular groove is also formed on the top inner wall of the frame 101, and the connecting rod 206 passes through the through hole. A horizontal plate 207 is also provided on the outer wall of the connecting rod 206, and distance sensors 208 are provided at the four corners of the lower surface of the horizontal plate 207. Under the gravity of the counterweight 209, the connecting rod 206 can be kept perpendicular to the horizontal plane. At this time, the horizontal plate 207 on the outer side of the connecting rod 206 is parallel to the horizontal plane. The distance between the distance sensor 208 at the bottom of the horizontal plate 207 and the movable plate 104 can be detected by the distance sensor 208. When the values ​​detected by all distance sensors 208 are the same, it indicates that the movable plate 104 is just in a horizontal state, which is very convenient to use.

[0036] As one embodiment of the present invention, please refer to Figure 6 and Figure 7 The sealing mechanism includes a movable plate 303. A threaded hole is provided on one outer wall of the enclosure 107, and a screw 301 is threaded into the hole. An adjusting wheel 302 is provided at one end of the screw 301, and the other end of the screw 301 is rotatably connected to the movable plate 303. A limiting cylinder 306 is fixedly provided on one inner wall of the enclosure 107, and a limiting rod 305 is movably provided within the limiting cylinder 306. The end of the limiting rod 305 is connected to the outer wall of the movable plate 303. A sealing block 304 is fixedly provided on the outer wall of the movable plate 303 away from the screw 301. The specific material of the block 304 is not limited. In this embodiment, preferably, the material of the sealing block 304 is rubber, and the sealing block 304 fits the inner wall of the guide port 109. When it is necessary to seal the guide port 109, the adjusting wheel 302 can be rotated to drive the screw 301 to rotate. Due to the limiting action of the limiting rod 305, the screw 301 can drive the moving plate 303 to move, so that the sealing block 304 on the outer wall of the moving plate 303 enters the guide port 109 and closely adheres to the inner wall of the guide port 109, thus achieving the sealing of the guide port 109. It is very convenient to use.

[0037] As one embodiment of the present invention, please refer to Figure 4The adjustment mechanism includes a lifting plate 401 disposed on the bottom outer wall of the piston block 110, and the lifting plate 401 has a U-shaped cross section. A fixing plate 402 is fixedly disposed on one side outer wall of the sample dispensing box 105, and the lifting plate 401 passes through the fixing plate 402. A limit hole is opened on the outer wall of the fixing plate 402, and a stud 403 is threadedly connected in the limit hole. A turntable 404 is fixedly disposed on the top of the stud 403, and the bottom end of the stud 403 is rotatably connected to the lifting plate 401. When it is necessary to adjust the position of the piston block 110, the turntable 404 can drive the stud 403 to rotate, and the stud 403 can drive the lifting plate 401 to move. The lifting plate 401 can then drive the piston block 110 to move up and down together, effectively realizing the adjustment of the sample dispensing rate and improving the performance.

[0038] As one embodiment of the present invention, please refer to Figure 3 The fixing assembly includes fixing plates 402 disposed on the outer walls of both sides of the sample loading box 105. A stud 403 is fixedly disposed on the upper surface of the fixing plate 402, and the stud 403 penetrates the movable plate 104. A nut 503 is threaded onto the outer side of the stud 403, and the nut 503 is located above the movable plate 104. A stop bar 504 and a rubber block 505 are also disposed on the upper surface of the side plate 501, with the top of the stop bar 504 lower than the top of the rubber block 505. When it is necessary to fix the sample loading box 105 and the movable plate 104 together, the fixing plate 402 can be fixed first. The stud 403 passes through the movable plate 104. Then, the nut 503 can be rotated to the outside of the stud 403 and tightened, so that the rubber block 505 is compressed until the top of the push rod 504 abuts against the lower surface of the movable plate 104. At this time, not only can the sample box 105 and the movable plate 104 be locked and fixed, but the sample box 105 and the movable plate 104 can also be kept parallel, resulting in better performance. Reverse rotation of the nut 503 can remove the sample box 105 from the movable plate 104 for easy cleaning.

[0039] As one embodiment of the present invention, please refer to Figure 2 The telescopic component 203 is connected to a switch via a wire, and the switch is electrically connected to a controller. The controller and the distance sensor 208 are electrically connected. The specific structure of the controller is not limited. In this embodiment, preferably, the controller is a microprogrammed controller.

[0040] In use, the frame 101 can be placed above the water bath. The movable plate 104 can then be leveled using a leveling mechanism to ensure the sample loading box 105 is horizontal. After leveling, the position of the water bath can be moved so that the different sample loading tubes 108 are aligned with the filling ports of the water baths used for parallel experiments. Then, the materials required for the parallel experiments can be added to the sample loading box 105 through the filling cylinder 106. At this time, the piston block 110 in the sample loading box 105 is in a state of blocking the guide port 109. When it is necessary to add materials to different water baths uniformly, the position of the piston block 110 can be adjusted using an adjusting mechanism. With the feed inlet 109 exposed, the material in the sample loading box 105 can be guided into the enclosure 107 through the feed inlet 109, and then added to the water bath through the sample loading tube 108. This effectively enables synchronous feeding of different water baths. Since the sample loading box 105 is in a horizontal state, the material flow rate entering different feed inlets 109 remains consistent, making the comparative experimental results more accurate. The more the piston block 110 moves down, the greater the material flow rate, allowing for flexible control of the feeding rate. At the same time, the sealing mechanism can also block part of the feed inlets 109, allowing for flexible control of the number of control groups in parallel experiments, resulting in better performance.

[0041] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
