Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a surface water sampling and monitoring device. Background Technology

[0002] Surface water quality monitoring is a crucial part of environmental protection work, playing a vital role in assessing the health status of water bodies and providing early warnings of pollution incidents. To obtain accurate water quality data, on-site sampling is an essential first step.

[0003] Portable sampling and testing devices are typically used when conducting surface water sampling. These devices generally integrate storage space for sample containers (such as test tubes or sampling bottles) and probes for preliminary on-site testing. Operators carry the device to the sampling point, collect water samples, seal some of them, and perform rapid on-site testing on the rest.

[0004] For ease of access, many existing devices place the test tube boxes or racks for holding sampling tubes on the upper part or outside of the enclosure. However, this design has revealed significant shortcomings in practical applications. Surface water sampling often involves complex environments, including transportation on foot and amidst bumps and rough terrain. The test tube boxes placed on the upper or outer part of the equipment are mostly made of glass or hard plastic, making them structurally fragile. During movement and operation, they are easily broken or the test tubes are damaged due to accidental bumps, vibrations, or drops. This not only causes economic losses but, more seriously, can lead to the loss of precious water samples, rendering the sampling work futile and affecting the timeliness and accuracy of monitoring tasks. Therefore, this utility model proposes a surface water sampling and detection device to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a surface water sampling and testing device, which aims to improve the problems of low reliability and imperfect functional design of some existing surface water sampling and testing devices, such as the easy breakage during transportation and use due to improper placement or insecure fixing of the test tube box, and the inconvenience caused by the lack of place to put the detection probe after use. This utility model aims to provide a surface water sampling and testing device with an improved structure that can effectively solve the above problems.

[0006] This utility model G provides a surface water sampling and testing device, including a housing, a cover pivotally connected to the top of the housing, and a test tube box that can be stored at the bottom of the housing; and a connecting mechanism for locking or releasing the test tube box.

[0007] The connecting mechanism is the key to realizing the core function of this utility model, and it includes a fixed block, a push rod, a spring, a moving block, a buckle assembly, a fixed plate, and a connecting rod.

[0008] Furthermore, the fixed block is fixedly connected to the inner wall of the box, and the push rod slides through the fixed plate; the spring is sleeved on the push rod, and its two ends abut against the test tube box and the moving block respectively; the moving block is fixedly connected to one end of the push rod; the buckle assembly is connected to the moving block and is used to interact with the test tube box; the fixed plate is fixed to the fixed block; the connecting rod is fixedly connected to the fixed plate, and one end of the connecting rod can be engaged with the sliding groove opened on the moving block. Through this ingenious structural combination, a complete push-lock system is formed.

[0009] Preferably, the buckle assembly includes a long rod and a locking block. One end of the long rod is fixedly connected to the bottom of the movable block, and the other end is connected to the locking block. The outer wall of the test tube box is provided with a corresponding slot for engaging with the locking block. This direct engagement structure ensures the reliability of the fixation.

[0010] Preferably, the other end of the push rod extends towards the outer wall of the test tube box as the actuating end, so that when the test tube box is pushed into the box, it is pushed by its outer wall, thereby smoothly driving the moving block to move along the axial direction of the push rod and compressing the spring, thus initiating the entire locking process.

[0011] Preferably, the surface water sampling and detection device further includes a fixing mechanism, which is installed on the inner wall of the box cover and is specifically used to install the electric conductivity probe. This cleverly utilizes the unused space of the box cover and enhances the overall functionality of the device.

[0012] Preferably, as a specific implementation, the fixing mechanism includes a corner bracket and a long block; the corner bracket is fixed to the inner wall of the box cover by bolt two, while the long block is fixedly connected to the corner bracket by bolt one. This structure, which is connected by standard parts, is simple and stable, and is easy to produce and assemble.

[0013] Preferably, the long block has a long slot for accommodating the conductivity probe, and the long block also has a break that communicates laterally with the long slot, so that the conductivity probe can be conveniently inserted into or removed from the long slot through the break, which greatly facilitates the user's operation.

[0014] Preferably, the connection between the connecting rod and the sliding groove forms a push-locking structure. The structure can reliably lock the moving block when the test tube box is pushed for the first time, and can sensitively release the lock on the moving block when the test tube box is pushed for the second time, realizing the operation of "one push to lock, push again to open".

[0015] Preferably, as a further limitation of the latching structure, one end of the connecting rod is fixedly connected to the fixed plate, and the other end serves as a free end for engaging with the slide groove; the slide groove is constructed as a heart-shaped guide channel, and this specific channel shape can precisely guide the free end of the connecting rod to move along a preset trajectory, thereby accurately realizing the switching between locking and unlocking functions.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that test tube boxes are easily broken during transportation and use due to insecure fixing or improper placement by setting a push-type locking connection mechanism consisting of a push rod, spring, moving block, connecting rod and buckle assembly at the bottom of the box.

[0018] 2. This utility model solves the problem in the prior art of having nowhere to put the conductivity probe after it gets wet by adding a fixing mechanism consisting of a corner bracket and a long block with a long groove and a break on the inside of the box cover. This achieves the effect of providing a dedicated and convenient storage location for the probe, avoiding cross-contamination, and improving the cleanliness and efficiency of operation.

[0019] 3.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Reference Figures 1 to 5 This utility model provides a surface water sampling and detection device, which aims to solve the problems in the prior art where the test tube box 4 of the sampling device is easily broken due to collision and there is nowhere to put the detection probe after use.

[0034] like Figure 1 As shown, the surface water sampling and testing device includes a housing 1 and a cover 5 pivotally connected to the top of the housing 1. The housing 1 serves as the mounting base and housing space for the entire device, and the cover 5 is used to close the top opening of the housing 1. The device also includes a test tube box 4 that can be stored at the bottom of the housing 1. The test tube box 4 is used to store the collected water samples. In order to achieve stable installation and convenient access for the test tube box 4, the device also includes a connecting mechanism 2. The connecting mechanism 2 is used to detachably lock or release the test tube box 4 at the bottom of the housing 1.

[0035] Reference Figure 1 and Figure 3The connecting mechanism 2 is one of the core innovations of this solution. It includes a fixed block 24, a push rod 21, a spring 23, a moving block 22, a snap-fit ​​assembly 28, a fixing plate 25, and a connecting rod 26. The fixed block 24 is fixedly connected to the inner wall of the housing 1, serving as the mounting base for the connecting mechanism 2. The push rod 21 slides through the fixing plate 25 and can reciprocate along its own axis. The spring 23 is sleeved on the push rod 21, with its two ends abutting against the test tube box 4 and the moving block 22, respectively, to provide a reciprocating motion for the moving block 22. The movable block 22 is fixedly connected to the end of the push rod 21 away from the test tube box 4 and moves synchronously with the push rod 21. The snap-fit ​​assembly 28 is connected to the movable block 22 and is used to directly snap into the test tube box 4. The fixing plate 25 is fixed on the fixing block 24 and is used to install the connecting rod 26. The connecting rod 26 is fixedly connected to the fixing plate 25, and one end of it can be snapped into the sliding groove 27 opened on the movable block 22. Through this engagement, the locking and unlocking functions of the movable block 22's movement state are realized.

[0036] Reference Figure 3 , Figure 4 and Figure 5 One end of the push rod 21 extends towards the outer wall of the test tube box 4 as the actuating end. When the test tube box 4 is pushed into the box body 1, it is pushed by the outer wall of the box body 1, thereby driving the moving block 22 to move along the axial direction of the push rod 21 and compressing the spring 23. The latching assembly 28 includes a long rod 281 and a latching block 282. One end of the long rod 281 is fixedly connected to the bottom of the moving block 22, and the other end is connected to the latching block 282. Correspondingly, the outer wall of the test tube box 4 is provided with a latching groove 283 for engaging with the latching block 282. When the moving block 22 is pushed to the predetermined position, the latching block 282 at its bottom can just be engaged in the latching groove 283 of the test tube box 4, thereby achieving the initial positioning of the test tube box 4.

[0037] Meanwhile, the cooperation between the connecting rod 26 and the slide 27 plays a crucial role in locking the position of the moving block 22. One end of the connecting rod 26 is fixed to the fixed plate 25, and the other end serves as a free end to cooperate with the slide 27. The slide 27 is opened on the side of the moving block 22 and is constructed as a heart-shaped guide channel to guide the free end of the connecting rod 26 to move along a specific trajectory. When the test tube box 4 is pushed for the first time, the moving block 22 moves, and the free end of the connecting rod 26 slides into a locking position along the guide trajectory of the slide 27, thereby locking the moving block 22 and preventing it from resetting under the action of the spring 23. At this time, the test tube box 4 is completely locked. When the test tube box 4 is pushed for the second time, the moving block 22 is pushed further in, and the free end of the connecting rod 26 will cross an inflection point and enter another release trajectory of the slide 27, thereby disengaging from the locking position. The moving block 22 then quickly resets under the elastic force of the spring 23, causing the locking block 282 to disengage from the locking groove 283, and finally releasing the lock on the test tube box 4. This push-type latching structure, consisting of connecting rod 26 and slide groove 27, ensures the convenience and reliability of device operation.

[0038] Reference Figure 2 and Figure 5 The device also includes a fixing mechanism 3, which is installed on the inner wall of the box cover 5. It is specifically used to place the conductivity probe 6 after use, so as to prevent the probe from getting wet and having nowhere to be placed or from contaminating other items inside the box 1.

[0039] Reference Figure 2 and Figure 5 The fixing mechanism 3 includes a corner bracket 34 and a long block 31. The corner bracket 34 is firmly fixed to the inner wall of the box cover 5 by bolt 2 36, providing a stable installation base for the long block 31. The long block 31 is fixedly connected to the corner bracket 34 by bolt 1 35, thereby suspending it inside the box cover 5.

[0040] Reference Figure 5 The long block 31 has a long slot 32 for accommodating the conductivity probe 6. The size of the long slot 32 is adapted to the rod of the conductivity probe 6. In order to facilitate the insertion and removal of the probe, the long block 31 also has a break 33 that is laterally connected to the long slot 32. In use, the conductivity probe 6 can be conveniently placed laterally into the long slot 32 through the break 33, or taken out from the long slot 32. The operation is simple and quick.

[0041] The implementation principle of this application embodiment is as follows: When it is necessary to store the test tube box 4, the user pushes the test tube box 4 into the bottom of the box 1. The outer wall of the test tube box 4 will impact and push the push rod 21 to slide inward. The push rod 21 drives the moving block 22 to move inward synchronously and compresses the spring 23 located between the fixed block 24 and the moving block 22. During this process, the free end of the connecting rod 26 connected to the fixed plate 25 will slide in the slide groove 27 on the side of the moving block 22. When the moving block 22 reaches the locking position, the connecting rod 26 will be locked into the locking area of ​​the slide groove 27, thereby preventing the moving block 22 from returning under the elastic force of the spring 23. At the same time, the locking block 282 at the end of the long rod 281 fixed to the bottom of the moving block 22 will also be locked into the locking groove 283 at the bottom of the test tube box 4, thereby locking the test tube box 4 securely in the box 1.

[0042] When it is necessary to remove the test tube box 4, the user gently pushes the test tube box 4 inward again. This action pushes the moving block 22 a small distance further in, causing the free end of the connecting rod 26 to pass a guide sill in the slide groove 27 and enter the release track. Once the connecting rod 26 is out of the locking area, the restriction on the moving block 22 is released, and the spring 23 immediately releases its elastic force, pushing the moving block 22 to quickly reset. As the moving block 22 resets, the locking block 282 disengages from the locking groove 283, releasing the fixation on the test tube box 4, and the user can easily pull out the test tube box 4.

[0043] After sample testing, if the conductivity probe 6 is wet, the user can open the box cover 5 and place the conductivity probe 6 into the long slot 32 through the break 33 of the long block 31 on the fixing mechanism 3, which realizes the probe can be put in and taken out at any time and keeps the inside of the box clean.
