Technical Field

[0001] This utility model belongs to the technical field of water quality monitoring equipment, specifically relating to a portable water quality monitoring instrument. Background Technology

[0002] With the increasing demand for water environment monitoring, portable water quality monitors are widely used because they can quickly monitor water quality parameters on-site. Existing portable water quality monitors usually integrate a display to show monitoring data in real time. However, most of these displays adopt a fixed exposed design or a simple folding structure: the former increases the overall size of the device, with the display protruding from the body, making it easy to be damaged by collisions during carrying, and also occupies storage space, making it inconvenient to put into backpacks or other portable carriers; the latter, although foldable, has poor folding structure stability and is prone to accidental unfolding during carrying, also resulting in insufficient portability.

[0003] The obtrusive design of this display not only reduces the portability of the device but may also affect its lifespan due to structural defects, making it difficult to meet the requirements of miniaturization and interference resistance in scenarios such as field operations and emergency monitoring. Therefore, there is an urgent need for a portable water quality monitor that can solve the problem of the obtrusive display and improve portability. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a portable water quality monitor, which solves the technical problems of the obtrusive display and inconvenience of carrying in the prior art.

[0008] Optionally, a pressing rod is provided on the side of the abutment rod away from the elastic member, and a through groove is provided on the side wall of the movable rail. The end of the pressing rod away from the abutment rod passes through the through groove and extends to the outside of the movable rail. The pressing rod can push the abutment rod towards the side of the elastic member after being pressed, so that the abutment rod is not engaged with the slot.

[0009] Optional, also includes: An elastic buffer is disposed inside the fixed rail and below the movable rail, and the elastic buffer is used to provide cushioning for the movable rail.

[0010] Optionally, a sealing strip is provided around the edge of the top cover.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figure 1 and Figure 2 As shown, two telescopic slide rails 4 are vertically mounted on the side walls of the housing 1. Each telescopic slide rail 4 includes a fixed rail 401 and a movable rail 402. The fixed rail 401 is fixed inside the housing 1, and the movable rail 402 is slidably connected to the fixed rail 401. This structure allows the control panel 2 to rise and fall as the movable rail 402 slides. Several vertically evenly distributed slots 6 are provided on the inner side wall of the fixed rail 401. A locking rod 7 is located between the fixed rail 401 and the movable rail 402. One end of the rod is swayingly connected to the control panel 2, and the other end, the locking end 8, can be locked into the slot 6. When it is necessary to adjust the height of the control panel 2, simply disengage the locking end 8 from the slot 6, slide the movable rail 402 to the appropriate position, and then lock the locking end 8 into the corresponding slot 6. At the same time, the other side of the control panel 2 away from the swaying end abuts against the top of the housing 1, thus fixing the control panel 2.

[0025] Specifically, two telescopic slide rails 4 are vertically installed on the side walls of the housing 1. The fixed rail 401 of each telescopic slide rail 4 is connected to the movable rail 402 for lifting and sliding, which can drive the control panel 2 to rise and fall smoothly, meeting the flexible adjustment needs of the height of the control panel 2 in different usage scenarios. In addition, there can be two movable rails 402 to increase the lifting range of the telescopic slide rails 4. Several vertically evenly distributed slots 6 on the inner side wall of the fixed rail 401 cooperate with the locking end 8 of the locking rod 7 to achieve a stable locking after the control panel 2 is adjusted to a suitable height, preventing displacement during use. In addition, the opening direction of several slots 6 is set at an angle to facilitate quick locking of the locking end 8 and the slot 6. At the same time, the structure of the locking rod 7 with one end swinging to the control panel 2 and the other end locking to the slot 6 can effectively support the control panel 2 and ensure stability during operation. The telescopic slide rails 4 symmetrically arranged on both sides make the force more balanced, improve the reliability of the overall structure, and further enhance the ease of operation and adaptability of the equipment.

[0026] like Figure 1 and Figure 2As shown, one end of the elastic element 9 is mounted on the locking rod 7, and the other end is mounted on the inner wall of the fixed rail 401, which is the side away from the slot 6. When the elastic element 9 is in its natural state, it applies a pushing force to the locking rod 7 towards the slot 6, keeping the locking end 8 of the locking rod 7 engaged with the slot 6. The continuous action of the elastic element 9 on the locking rod 7 creates a pre-tightening force that engages the locking end 8 with the slot 6, ensuring the stability of the locking state without external interference. During operation, when unlocking is required, an external force is applied to overcome the elastic force of the elastic element 9, causing the locking end 8 to disengage from the slot 6. When the external force is removed, the elastic force of the elastic element 9 automatically pushes the locking rod 7 back to its original position, causing the locking end 8 to re-engage with the slot 6.

[0027] Furthermore, the cooperation between the elastic element 9, the locking lever 7, and the fixed rail 401 ensures a stable engagement between the locking end 8 and the slot 6 without additional operation. This prevents the locking end 8 from accidentally disengaging from the slot 6 due to equipment shaking or minor collisions, thus enhancing the reliability of the locking structure. Simultaneously, the elastic force of the elastic element 9 provides a reset force for the locking lever 7, making the locking operation more convenient. During height adjustment of the control panel 2, unlocking can be completed with a single application of external force, and the lock automatically returns to its original position after release, improving operational efficiency.

[0028] like Figure 1 and Figure 4 As shown, rotating shafts 3 are respectively provided on the top two side walls of the control panel 2, and the rotating shafts 3 extend horizontally. The locking lever 7 includes a sleeve 701 and an abutment rod 702. The sleeve 701 is rotatably sleeved on the rotating shaft 3, and the sleeve 701 can rotate relative to the control panel 2 around the axis of the rotating shaft 3. One end of the abutment rod 702 is fixedly connected to the sleeve 701, and the two form an integral structure. The other end of the abutment rod 702 is a snap-fit ​​end 8, which can snap into the slot 6 on the fixed rail 401. The rotational cooperation between the sleeve 701 and the rotating shaft 3 realizes the swing connection between the locking lever 7 and the control panel 2, so that the abutment rod 702 can rotate with the sleeve 701 around the rotating shaft 3, thereby adjusting the relative position of the snap-fit ​​end 8 and the slot 6. The abutment rod 702 transmits force through its fixed connection with the sleeve 701, ensuring stable support for the control panel 2.

[0029] The rotational engagement between sleeve 701 and shaft 3 provides a stable fulcrum for the locking lever 7, reducing wear during the swing process and extending the structural service life. The fixed connection between the abutment lever 702 and sleeve 701 ensures effective force transmission, making the engagement between the locking end 8 and slot 6 more secure, while also enhancing the support strength for the control panel 2 and preventing it from shaking during use. This structure makes the swing trajectory of the locking lever 7 more stable and improves the overall structural precision.

[0030] like Figure 1 and Figure 2As shown, a pressing rod 10 is provided on the side of the abutment rod 702 away from the elastic member 9. The pressing rod 10 is fixedly connected to the abutment rod 702 and extends away from the elastic member 9. A through groove 11 is provided on the side wall of the movable rail 402, and the through groove 11 extends along the height direction of the movable rail 402. The end of the pressing rod 10 away from the abutment rod 702 passes through the through groove 11 and extends to the outside of the movable rail 402. The pressing rod 10 can move along the extension direction of the through groove 11. When the pressing rod 10 is subjected to an external force toward the elastic member 9, the pressing rod 10 drives the abutment rod 702 to move toward the elastic member 9, causing the locking end 8 to disengage from the locking groove 6.

[0031] The push-button 10 provides a clear point of force for the unlocking operation, and together with the guiding effect of the through slot 11, makes the unlocking operation more convenient and effortless. The push-button 10 extends through the opening to the outside of the movable rail 402, allowing operation without additional disassembly or flipping of parts.

[0032] like Figure 1 and Figure 5 As shown, the elastic buffer 12 is disposed inside the fixed rail 401 and located below the movable rail 402. One end of the elastic buffer 12 is connected to the fixed rail 401, and the other end extends toward the movable rail 402. When the movable rail 402 slides down along the fixed rail 401 to its limit position, the bottom of the movable rail 402 contacts the elastic buffer 12.

[0033] The elastic buffer 12, in conjunction with the fixed rail 401 and the movable rail 402, effectively mitigates the impact force during the descent of the movable rail 402, reduces wear and vibration between structures, and extends the service life of the telescopic slide rail 4. For field applications, this structure reduces the risk of collision damage between the movable rail 402 and the fixed rail 401 during equipment movement, enhancing the equipment's durability.

[0034] like Figure 1 As shown, one side of the top cover 13 is sway-connected to one side of the top of the housing 1, and the top cover 13 can rotate around the connecting shaft. When the top cover 13 rotates to the position covering the top of the housing 1, the top cover 13 can cover the control panel 2; when the top cover 13 rotates to the position away from the top of the housing 1, the control panel 2 is exposed.

[0035] The swing connection between the top cover 13 and the housing 1 allows the control panel 2 to be effectively covered when the device is not in use, preventing external dust, water droplets, or foreign objects from directly contacting the control panel 2 and protecting its surface structure and internal components. The top cover 13 makes the overall structure of the device more complete. When stored, the control panel 2 is enclosed between the top cover 13 and the housing 1, reducing the impact of external collisions on the control panel 2 and further improving the portability and protective performance of the device.

[0036] like Figure 1As shown, the sealing strip 5 is distributed along the outer periphery of the top cover 13. When the top cover 13 covers the top of the housing 1, one side of the sealing strip 5 is in contact with the top cover 13, and the other side is in contact with the edge of the top of the housing 1, forming a sealing structure. The cooperation between the sealing strip 5, the top cover 13, and the housing 1 enhances the sealing performance when the top cover 13 is covering, effectively preventing moisture, dust, etc. from entering the equipment. It is especially suitable for humid or dusty outdoor environments, protecting the control panel 2 and other components inside the housing 1 from corrosion.

[0037] like Figure 1 As shown, a water storage box 14 is installed inside the housing 1 to store the water to be monitored. A water pump 15 is installed inside the housing 1, with its inlet connected to an external water source and its outlet connected to the water storage box 14, used to pump the water to be monitored into the water storage box 14. A drain pump 16 is installed inside the housing 1, with its inlet connected to the water storage box 14 and its outlet connected to the outside, used to drain the monitored water from the water storage box 14. A water quality monitor 17 is installed inside the water storage box 14 and is electrically connected to the control panel 2, used to monitor the parameters of the water to be monitored and transmit the data to the control panel 2.

[0038] The integrated design of the water storage box 14, water pump 15, drainage pump 16, and water quality monitor 17 enables the equipment to independently collect, monitor, and discharge water samples without relying on external containers, thus improving the overall integration of the equipment. The water pump 15 and drainage pump 16 automate water sample processing, reducing manual operation steps.

[0039] like Figure 1 As shown, an overflow pipe 18 is located on one side of the top of the water storage box 14. One end of the overflow pipe 18 is connected to the interior of the water storage box 14, and the other end extends to the outside of the tank 1. When the water level to be monitored in the water storage box 14 exceeds the preset height, the excess water is discharged from the water storage box 14 through the overflow pipe 18. When the water level in the water storage box 14 reaches the inlet height of the overflow pipe 18, the excess water is automatically discharged through the overflow pipe 18, maintaining the water level in the water storage box 14 within a safe range. During the working process, when the water pump 15 supplies water to the water storage box 14, if the water supply exceeds the capacity of the water storage box 14, the excess water is discharged in time through the overflow pipe 18 to prevent water from overflowing from the water storage box 14 into other areas inside the tank 1.

[0040] like Figure 1 and Figure 3As shown, interface plate 19 is located on one side of housing 1. Interface plate 19 has a water inlet 1901, a drain outlet 1902, an overflow outlet 1903, and an air inlet 1904. Water inlet 1901 connects to the water inlet of water pump 15, drain outlet 1902 connects to the water outlet of drainage pump 16, and overflow outlet 1903 connects to the end of overflow pipe 18 furthest from water storage box 14. Air inlet 1904 connects to water pump 15 and drainage pump 16 via pipelines, supplying them with the necessary air for operation. The interface plate 19 centralizes and standardizes the external connections of the equipment, avoiding connection errors or detachments caused by messy pipelines, and improving the ease of operation. Dedicated connections between each interface and corresponding component ensure unobstructed water and air passages, reducing the risk of leakage.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
