Abstract
Description
Technical Field
[0001] This application relates to the technical field of experimental equipment, and in particular to a test bottle inverting device and an automated testing device. Background Technology
[0002] In the field of environmental monitoring and water treatment technology, rapid and accurate component analysis of wastewater samples is crucial to ensuring the effectiveness of monitoring work. Specifically, before testing water samples in test bottles using a spectrometer, chemical reagents such as potassium permanganate are typically added to the water sample. The absorbance is then measured using a spectrometer to determine the degree of pollution in the corresponding river body.
[0003] In the operation of automated testing equipment, a tilter is used to drive the test bottles placed inside to tilt, allowing the water sample to drain naturally due to its own weight. After the water sample is drained, the inverted test bottles are cleaned, then returned to their original position and dried, thus enabling the reuse of the test bottles and ensuring the stable operation of continuous automated water sample testing. However, due to the limitations of the automated equipment's high-efficiency operation, the time for the tilter to tilt the test bottles and allow for drainage must be strictly controlled. Due to the fluid flow properties and surface tension, a small amount of residual liquid may remain at the edge of the test bottle opening. When the test bottle is returned to its original position with the tilter, this residual droplet will flow along the outer wall of the test bottle. Even after the subsequent drying process, the solute in the residual liquid will still precipitate on the outer wall of the test bottle and form stains. These stains will interfere with the incident and transmission effects of light during spectral detection, ultimately reducing the detection accuracy when the test bottle is refilled with water sample for testing, thus affecting the overall accuracy of the detection structure. Summary of the Invention
[0004] In view of this, it is necessary to provide a test bottle inversion device and an automated testing equipment that can solve the above-mentioned technical problems.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution: A test bottle inverting device, the test bottle inverting device comprising: A trough body, the trough body enclosing a receiving cavity, and a stop bar provided on the trough body to be received within the receiving cavity; the stop bar has an arc-shaped outer peripheral surface; An inverter, which is housed within the receiving cavity, is used to insert the body portion of a test bottle, and the inverter is capable of clamping and fixing the inserted test bottle. A rotary drive component is mounted on the groove and connected to the inverter via a drive shaft; An arc rod is movably connected to the drive shaft and can slide along the radial direction of the drive shaft. A ring is provided at one end of the arc rod away from the drive shaft, and absorbent cotton is embedded within the ring. A drainage hole is provided at the location of the absorbent cotton in the ring. The arc rod includes an arc-shaped segment and a connector. A stop bar can abut against the arc-shaped segment through its outer circumferential surface to provide a force for the arc rod to move on the drive shaft. A waist-shaped hole is provided on the connector, and the connector is sleeved onto the drive shaft through the waist-shaped hole and slidably connected to the drive shaft. The arc rod is also equipped with a stop block, which is located on the flipping path of the test bottle. When the ring body abuts against the edge of the bottle mouth through the absorbent cotton, the stop block can abut against the bottle mouth to drive the arc rod and the test bottle to flip synchronously. During the flipping process of the inverter, the ring body can abut against the edge of the bottle mouth through the absorbent cotton, and the arc rod can collide with the stop rod to drive the absorbent cotton to squeeze the edge of the bottle mouth and cause the absorbent cotton to undergo compression deformation.
[0006] In one embodiment, the number of drainage holes is configured to be multiple, and the multiple drainage holes are arranged sequentially at intervals along the circumferential direction of the ring body; Alternatively, the drain hole may be annular in shape.
[0007] In one embodiment, the absorbent cotton is flush with the ring.
[0008] In one embodiment, the arc rod is configured as a metal rod.
[0009] In one embodiment, the rotary drive is configured as a motor.
[0010] In one embodiment, the inverter includes a cylinder and a flexible member, the flexible member being installed inside the cylinder and capable of deforming under pressure from the test bottle to clamp and fix the test bottle; The cylinder is connected to the drive shaft.
[0011] This application also provides an automated testing device, including the test bottle inverting device described above.
[0012] Due to the application of the above solution, this application has the following advantages compared with the prior art: The test bottle inverting device and automated detection equipment claimed in this application, by setting up an arc rod that moves with the test bottle, allows the absorbent cotton on the ring of the arc rod to automatically compress and deform at the edge of the test bottle's mouth during the inverting process. This allows the compressed absorbent cotton to absorb and remove residual liquid at the edge of the bottle mouth when the test bottle is returned to its upright position, thus avoiding the phenomenon of residual dripping at the edge of the bottle mouth due to fluid characteristics and surface tension. This prevents stains from forming on the outer wall of the test bottle after treatment by the inverting device, ensuring the cleanliness of the test bottle during recycling and improving the detection accuracy of the water sample spectral analysis when the test bottle is reused, thereby meeting the needs for rapid and accurate component analysis of water samples.

[0024] like Figure 1 As shown, the test bottle inverting device 100 claimed in this application is used in automated testing equipment to invert a test bottle 200 containing a water sample, allowing the water sample to be automatically discharged from the test bottle 200 by gravity. Here, the automated testing equipment can perform fully automated spectral analysis on the water sample contained in the test bottle 200 to determine the actual degree of pollution in the corresponding river water body.
[0025] like Figures 1 to 5As shown, the test bottle inverting device 100 provided in this application includes a tank 10, an inverter 20, a rotary drive 30, and an arc rod 40. The tank 10 encloses a receiving cavity 110, and a stop bar 11 is provided on the tank 10 and received within the receiving cavity 110. The inverter 20 is received within the receiving cavity 110 and is used for inserting the bottle body 210 of the test bottle 200, and the inverter 20 can clamp and fix the inserted test bottle 200. The rotary drive 30 is mounted on the tank 10 and connected to the inverter 20 via a drive shaft 31. The arc rod 40 is movably connected to the drive shaft 31. And can slide along the radial direction of the drive shaft 31; the end of the arc rod 40 away from the drive shaft 31 is provided with a ring 410, the ring 410 is embedded with water-absorbing cotton 420, and the ring 410 has a drain hole 430 at the position of the water-absorbing cotton 420; wherein, during the process of the inverter 20 driving the test bottle 200 to flip, the ring 410 can abut against the edge 221 of the bottle mouth of the test bottle 200 through the water-absorbing cotton 420, and the arc rod 40 can abut against the stop rod 11, so as to drive the water-absorbing cotton 420 to squeeze the edge 221 of the bottle mouth, and cause the water-absorbing cotton 420 to undergo compression deformation.
[0026] As can be seen from the above, the test bottle inverting device 100 of this application, by setting an arc rod 40 that can move with the test bottle 200, allows the inverter 20 to automatically drive the absorbent cotton 420 of the ring 410 on the arc rod 40 to undergo compression deformation at the edge 221 of the bottle mouth of the test bottle 200 during the process of the test bottle 200 being rotated. This allows the compressed absorbent cotton 420 to absorb and remove residual liquid formed at the edge 221 of the bottle mouth when the test bottle 200 is returned to its upright position, thereby avoiding the phenomenon of residual dripping liquid at the edge 221 of the bottle mouth due to fluid characteristics and surface tension. This also prevents stains from forming on the outer peripheral wall 211 of the test bottle 200 after being treated by the test bottle inverting device 100, ensuring the cleanliness of the test bottle 200 during recycling and improving the detection accuracy of the water sample spectral analysis when the test bottle 200 is reused, thus meeting the needs of rapid and accurate component analysis of water samples.
[0027] In this application, the inverter 20 includes a cylindrical body (not shown) and a flexible member (not shown). The flexible member is installed inside the cylindrical body and can deform under the pressure of the test bottle 200 to clamp and fix the test bottle 200. That is, the inverter 20 of this embodiment clamps and fixes the bottle body 210 of the test bottle 200 in a tight fit manner, which facilitates the installation and removal of the test bottle 200 within the inverter 20.
[0028] Here, the flexible component can be specifically configured as a sealing ring embedded in the inner peripheral wall of the cylinder. Multiple sealing rings are arranged sequentially and at intervals inside the cylinder along the insertion direction of the test bottle 200 into the inverter 20. Of course, this is not the only option; for those skilled in the art, the flexible component can also be configured as a conical rubber sleeve installed inside the cylinder, which will not be elaborated upon here.
[0029] In this application, the rotary drive 30 is configured as a motor, which can be fixedly mounted on the outer wall of the tank 10 via a motor bracket. Of course, it is not limited to this; those skilled in the art will know that the rotary drive 30 can also be configured as a rotary cylinder, etc., which will not be elaborated here.
[0030] In this application, the arc rod 40 is configured as a metal rod with a certain degree of hardness. Specifically, the arc rod 40 can be configured as a stainless steel rod or a rod made of other metal materials, so that the arc rod 40 will not deform under the action of the test bottle 200.
[0031] like Figure 5 As shown, in one embodiment, the stop bar 11 has an arc-shaped outer peripheral surface 111; the arc bar 40 includes an arc segment 41, and the stop bar 11 can abut against the arc segment 41 through the outer peripheral surface 111 to provide the arc bar 40 with a force to move on the transmission shaft 31. As the test bottle 200 drives the arc bar 40 to continue to flip downward, the stop bar 11 can push the arc bar 40 at multiple angles by using action and reaction forces to meet the usage requirements of the arc bar 40 moving on the transmission shaft 31, and cause the absorbent cotton 420 to be compressed and deformed under the pushing of the bottle mouth edge 221.
[0032] like Figure 2 , Figure 4 As shown, the arc rod 40 also includes a connector 42, which has an oblong hole 421. The connector 42 is sleeved on the drive shaft 31 through the oblong hole 421 and is slidably connected to the drive shaft 31. This guides the movement of the connector 42 on the drive shaft 31, ensuring that when the stop rod 11 pushes the arc rod 40 in the opposite direction, the arc rod 40 drives the absorbent cotton 420 on the ring 410 to press the edge 221 of the bottle mouth in the positive direction and causes the absorbent cotton 420 to deform under pressure.
[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the arc rod 40 is further provided with a stop block 43, which is disposed on the flipping path of the test bottle 200; and when the ring body 410 abuts against the edge 221 of the bottle mouth through the absorbent cotton 420, the stop block 43 can abut against the bottle mouth 220 of the test bottle 200, so as to drive the arc rod 40 and the test bottle 200 to flip synchronously. Here, the stop block 43 can abut against the middle position of the bottle mouth 220, specifically by welding it to the arc rod 40.
[0034] like Figure 3 As shown, in one embodiment, the absorbent cotton 420 is flush with the ring 410, that is, the end face of the absorbent cotton 420 facing the bottle mouth edge 221 and the end face of the ring 410 facing the bottle mouth edge 221 are on the same plane. Here, the absorbent cotton 420 can be fixed inside the ring 410 by tight fitting or adhesive.
[0035] like Figure 3 , Figure 5 As shown, in one embodiment, the number of drainage holes 430 is configured to be multiple, and the multiple drainage holes 430 are arranged sequentially at intervals along the circumferential direction of the ring body 410; or, the drainage holes 430 are annular, so that the water squeezed out after the absorbent cotton 420 is compressed and deformed can be discharged outward through the drainage holes 430 under the action of gravity.
[0036] In summary, during the operation of the test bottle inverting device 100 of this application, the rotating drive 30 drives the inverter 20 to flip the test bottle 200 downwards; in the initial stage of flipping, the edge 221 of the bottle mouth of the test bottle 200 first forms a close contact with the absorbent cotton 420 arranged on the ring 410 of the arc rod 40, and at the same time, the bottle mouth 220 of the test bottle 200 and the stop block 43 on the arc rod 40 make mutual limiting contact. Relying on the positional interference between the stop block 43 and the bottle mouth 220, when the test bottle 200 is continuously tilted downwards, the stop block 43 can synchronously drive the arc rod 40 to rotate in conjunction with the transmission shaft 31. When the arc segment 41 of the arc rod 40 touches the fixed stop bar 11, the arc rod 40 will be blocked and limited by the stop bar 11. The arc rod 40 will drive the ring body 410 and the absorbent cotton 420 inside it to move towards the edge 221 of the bottle mouth through the sliding guide structure between the connector 42 and the transmission shaft 31, and squeeze the absorbent cotton 420, causing the absorbent cotton 420 to undergo compression deformation. The residual liquid adsorbed by it can be smoothly discharged through the drain hole 430 on the ring body 410. This realizes the immediate drainage and reset of the absorbent cotton 420, ensuring that it can continuously circulate and adsorb and thoroughly remove the residual liquid at the edge 221 of the bottle mouth of the test bottle 200.
[0037] In addition, this application also provides an automated testing device, including the test bottle inverting device 100 described above.
[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
