Description

Technical Field

[0001] This invention belongs to the technical field of wastewater sampling, and in particular relates to a test bottle clamping device and wastewater sampling equipment. Background Technology

[0002] In the field of environmental monitoring, wastewater sampling is a core step in obtaining raw data, and its accuracy and efficiency directly affect the scientific validity of environmental assessments and pollution control decisions. Currently widely used automated wastewater sampling equipment typically uses a pump to inject the wastewater to be tested into test bottles, and then a cap-screwing device automatically seals the clamped test bottles. In actual automated operation, the alignment accuracy between the cap-screwing device and the test bottle clamping device is crucial. Insufficient alignment accuracy can lead to axial or radial deviations between the cap and the bottle opening during the screwing process, causing hard friction between the threads. This phenomenon not only wears down or even damages the cap's thread structure, reducing its sealing performance and lifespan, but more seriously, the debris generated by friction may fall into the test bottle, contaminating the wastewater sample and interfering with subsequent analysis and testing results, severely affecting the accuracy and reliability of experimental data.

[0003] To alleviate the aforementioned alignment accuracy issues, existing technologies typically employ adding shock-absorbing pads to the clamping area of ​​the test bottle holder. This approach aims to utilize the elastic deformation of the shock-absorbing pads to provide a certain amount of floating space for the test bottle during screwing, thereby achieving minor automatic adjustments. However, in practical applications, relying solely on localized shock absorption at the clamping area has limited adjustment range and direction, often failing to fully compensate for larger alignment deviations. Therefore, the risks of hard friction between the cap and the test bottle, thread abrasion, and debris contamination remain, failing to fundamentally solve the problem. Summary of the Invention

[0004] In view of this, it is necessary to provide a test bottle clamping device and a wastewater sampling device to solve the above-mentioned technical problems.

[0005] A test bottle clamping device, comprising: The workbench is constructed with sliding grooves; The first clamping assembly includes a first push rod and a first flexible flat strip. The first push rod passes through the slide groove and is slidably engaged with the slide groove. The first flexible flat strip is annular and is located on the outside of the first push rod and connected to the first push rod. Furthermore, the first flexible flat strip is in a downward hanging state when not subjected to the force of the test bottle. The second clamping assembly is symmetrically arranged relative to the first clamping assembly in the length direction of the groove. The second clamping assembly includes a second push rod and a second flexible flat strip. The second push rod passes through the groove and is slidably engaged with the groove. The second flexible flat strip is annular and is located outside the second push rod and connected to the second push rod. Furthermore, the second flexible flat strip is in a downward hanging state when not subjected to the force of the test bottle. A driving component is installed at the bottom of the workbench and is connected to the first push rod and the second push rod respectively for controlling the first push rod and the second push rod to move towards each other or away from each other; The first flexible flat strip and the second flexible flat strip are arranged alternately along the length of the groove, and the first flexible flat strip and the second flexible flat strip cooperate with each other to suspend and clamp the test bottle.

[0006] In one embodiment, the first flexible flat strip and the first push rod are connected by a first threaded component; And / or, the second flexible flat strip and the second push rod are connected by a second threaded component.

[0007] In one embodiment, the number of both the first flexible flat strip and the second flexible flat strip is two; The two first flexible flat strips and the two second flexible flat strips are arranged alternately in the vertical direction.

[0008] In one embodiment, the first flexible flat strip and / or the second flexible flat strip are configured as rubber strips.

[0009] In one embodiment, the test bottle clamping device further includes a tray, which is disposed on the worktable for supporting the test bottle; The first flexible flat strip and the second flexible flat strip cooperate with each other and can drive the test bottle away from the tray and hold the test bottle in the air.

[0010] This application also claims protection for a wastewater sampling device, including a bottle cap screwing device and the aforementioned test bottle clamping device; The cap screwing device can screw the cap onto the test bottle, which is suspended and clamped by the test bottle clamping device.

[0011] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The test bottle clamping device and wastewater sampling equipment claimed in this application clamp the test bottle in cooperation with a first and second flexible flat straps that hang downwards. When moving in opposite directions, the friction generated between the straps and the surface of the test bottle is used to suspend and fix the test bottle in the air. This provides the necessary adaptive floating space for the test bottle held by the test bottle clamping device during the screwing process with the bottle cap, which can effectively compensate for the alignment deviation and thus fundamentally avoid the problems of thread grinding and debris contamination caused by hard contact between the bottle cap and the test bottle.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figure 1 As shown, the test bottle clamping device 100 claimed in this application is used to clamp and fix the test bottle 110 for subsequent screwing the cap 210 onto the test bottle 110. Here, the body of the test bottle 110 is cylindrical.

[0021] like Figure 2 , Figure 3 As shown, the test bottle clamping device 100 provided in this application includes a worktable 10, a first clamping assembly 20, a second clamping assembly 30, and a driving component (not shown). The worktable 10 is constructed with a slide groove 11. The first clamping assembly 20 includes a first push rod 21 and a first flexible flat strip 22. The first push rod 21 passes through the slide groove 11 and is slidably engaged with the slide groove 11. The first flexible flat strip 22 is annular and is located outside the first push rod 21 and connected to the first push rod 21. The first flexible flat strip 22 is in a downward hanging state when not subjected to the force of the test bottle 110. The second clamping assembly 30 is symmetrically arranged with respect to the first clamping assembly 20 in the length direction X of the slide groove 11. The second clamping assembly 30 includes a second push rod 31 and a... The second flexible flat strip 32 and the second push rod 31 are disposed through the slide groove 11 and slide in cooperation with the slide groove 11. The second flexible flat strip 32 is ring-shaped and is disposed on the outside of the second push rod 31 and connected to the second push rod 31. The second flexible flat strip 32 is in a downward hanging state when not subjected to the force of the test bottle 110. The driving component is installed at the bottom of the workbench 10 and is respectively connected to the first push rod 21 and the second push rod 31 for transmission, and is used to control the first push rod 21 and the second push rod 31 to move towards each other or away from each other. The first flexible flat strip 22 and the second flexible flat strip 32 are staggered in the X direction of the slide groove 11, and the first flexible flat strip 22 and the second flexible flat strip 32 cooperate with each other to suspend and clamp the test bottle 110.

[0022] As can be seen from the above, the test bottle clamping device 100 of this application clamps the test bottle 110 in cooperation with the downwardly suspended first flexible flat strip 22 and the second flexible flat strip 32. When moving in opposite directions, the friction generated between the test bottle 110 and the surface of the test bottle 110 is used to suspend and fix the test bottle 110. This provides the necessary adaptive floating space for the test bottle 110 clamped by the test bottle clamping device 100 during the screwing process with the bottle cap 210, which can effectively compensate for the alignment deviation, thereby fundamentally avoiding the problem of thread grinding and debris contamination caused by hard contact between the bottle cap 210 and the test bottle 110.

[0023] It should be noted that when the first flexible flat band 22 and the second flexible flat band 32 of this application are not suspended and holding the test bottle 110, the first flexible flat band 22 and the second flexible flat band 32 can hang downwards under their own weight. Furthermore, the portion of the first flexible flat band 22 furthest from the first push rod 21 and the portion of the second flexible flat band 32 furthest from the second push rod 31 both droop the most. Of course, those skilled in the art can also achieve the downward hanging state by adding pads between the first flexible flat band 22 and the first push rod 21, and / or between the second flexible flat band 32 and the second push rod 31.

[0024] When the test bottle clamping device 100 of this application is working, when the first flexible flat strip 22 and the second flexible flat strip 32 move in opposite directions under the drive of their respective first push rod 21 and second push rod 31, the first flexible flat strip 22 and the second flexible flat strip 32 push the test bottle 110 from two opposite directions. By utilizing the action and reaction forces, the test bottle 110 can be kept in a fixed position in the groove length direction X of the slide groove 11. During this process, by utilizing the friction between the first flexible flat strip 22 and the second flexible flat strip 32 and the test bottle 110, when the downward hanging parts of the first flexible flat strip 22 and the second flexible flat strip 32 just contact the test bottle 110 and are tightened, the two can provide an upward driving force in the vertical direction Z of the test bottle 110 and clamp the test bottle 110 in the air.

[0025] It should be noted that after the first flexible flat band 22 and the second flexible flat band 32 suspend and clamp the test bottle 110, the static friction between the first flexible flat band 22 and the second flexible flat band 32 and the test bottle 110 can be used to limit the test bottle 110 in the circumferential direction, which creates conditions for the subsequent screwing of the bottle cap 210 onto the test bottle 110.

[0026] In one embodiment, the first flexible flat strip 22 is connected to the first push rod 21 by a first threaded component (not shown); and / or, the second flexible flat strip 32 is connected to the second push rod 31 by a second threaded component (not shown), thereby facilitating the connection of the first flexible flat strip 22 to the first push rod 21 and the connection of the second flexible flat strip 32 to the second push rod 31.

[0027] Specifically, the first flexible flat strip 22 and the second flexible flat strip 32 are respectively fixed to the corresponding first push rod 21 and the corresponding second push rod 31 by corresponding first threaded parts and second threaded parts; wherein, the aforementioned first threaded parts and / or second threaded parts can be bolts, screws, etc., which will not be elaborated here.

[0028] Furthermore, the portion of the first flexible flat strip 22 that is fixed to the first push rod 21 by the first threaded component is bent in the opposite direction and placed against the outer peripheral wall of the first push rod 21. Specifically, the connection between the bent portion of the first flexible flat strip 22 and the outer peripheral wall of the first push rod 21 can be achieved by adhesive bonding. This can effectively increase the opening diameter of the first flexible flat strip 22, ensuring that the test bottle 110 will not touch the first flexible flat strip 22 during the process of passing through and lowering it.

[0029] Similarly, the portion of the second flexible flat strip 32 that is fixed to the second push rod 31 by the second threaded component is also bent in the opposite direction and adhered to and connected to the outer peripheral wall of the second push rod 31 by adhesive.

[0030] like Figure 2 As shown, in one embodiment, there are two first flexible flat strips 22 and two flexible flat strips 32; the two first flexible flat strips 22 and the two second flexible flat strips 32 are arranged alternately in the vertical direction Z, which can further improve the stability of the test bottle clamping device 100 in suspending and fixing the test bottle 110 when it is working.

[0031] Here, the first flexible flat strip 22 and / or the second flexible flat strip 32 are configured as rubber strips.

[0032] In one embodiment, the driving component can be a dual-axis cylinder, with two telescopic shafts connected to the first push rod 21 and the second push rod 31 respectively. This allows the test bottle clamping device 100 to control the first push rod 21 and the second push rod 31 to move in opposite directions or in opposite directions when the dual-axis cylinder is in operation. Of course, those skilled in the art will recognize that the driving component can also be a rotary motor or a rotary cylinder, and can be connected to the first push rod 21 and the second push rod 31 via two threaded connections in opposite directions. This will not be elaborated upon here.

[0033] like Figure 2, Figure 3 As shown, in one embodiment, the test bottle clamping device 100 further includes a tray 40, which is disposed on the worktable 10 and used to support the test bottle 110. The first flexible flat strap 22 and the second flexible flat strap 32 cooperate with each other to drive the test bottle 110 away from the tray 40 and suspend the test bottle 110 in mid-air. That is, the test bottle 110 can be placed on the tray 40 after passing through the overlapping portion of the first flexible flat strap 22 and the second flexible flat strap 32, so that the first flexible flat strap 22 and the second flexible flat strap 32 can subsequently suspend and clamp the test bottle 110 on the tray 40.

[0034] like Figure 1 As shown, this application also provides a wastewater sampling device 1000, including a bottle cap screwing device 200 and the aforementioned test bottle clamping device 100; the bottle cap screwing device 200 is capable of screwing the bottle cap 210 onto the test bottle 110 suspended and clamped by the test bottle clamping device 100.

[0035] It should be noted that the specific structure of the bottle cap screwing device 200 and the working principle of how the bottle cap 210 is held and automatically screwed onto the test bottle 110 can all adopt conventional methods of existing technology, and will not be elaborated here.

[0036] 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.

[0037] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
