Description

Technical Field

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

[0002] Portable water quality monitoring devices are widely used in various water quality testing scenarios, including rivers, lakes, industrial wastewater, and domestic water, due to their small size, portability, and wide applicability. They are core equipment in water environment monitoring, water pollution investigation, and daily water quality inspection. The integrity of the water quality probe, as the core testing component of the device, directly determines the accuracy of the water quality data and the lifespan of the equipment.

[0003] Currently, probes are highly susceptible to collisions, friction, and scratches with external objects, easily causing wear and damage to the probe's sensing elements. This not only leads to decreased detection accuracy and data distortion but can also directly cause probe failure, increasing equipment maintenance and replacement costs and affecting the normal operation of water quality monitoring. Some existing portable water quality monitoring devices have added telescopic drive components, which can electrically control the extension and retraction of the detection probe, thus solving the problem of probe lack of protection when the equipment is idle or being transported to some extent. However, these telescopic components rely entirely on the device's built-in battery for power. During long-term outdoor monitoring operations without an external power source, the device continuously consumes power. When the battery is low or there is a low-voltage power outage, the telescopic drive component will immediately stop working due to the power interruption, failing to complete the probe retraction action.

[0004] During subsequent handling, storage, and relocation of the equipment, the exposed probes still face the risk of bumps and damage. Therefore, this invention proposes a portable water quality monitoring device. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing portable water quality monitoring devices have exposed probes that are easily damaged by bumps and knocks. Furthermore, the use of an electric telescopic structure to store the probe results in the probe not being able to retract when the battery is low and power is off, leading to continued exposure and damage. Therefore, this invention proposes a portable water quality monitoring device.

[0006] The technical solution of this utility model is as follows: A portable water quality monitoring device includes a monitoring box body, a water quality detection probe fixedly connected to the bottom of the monitoring box body for monitoring water quality; a base plate disposed below the monitoring box body for protecting the water quality detection probe; symmetrically arranged first floats fixedly connected to both sides of the monitoring box body, and second floats disposed on the other two sides of the monitoring box body; a positioning component disposed between the second floats and the base plate for positioning the base plate.

[0007] Optionally, a buoyancy box is fixedly connected in the bottom plate, the buoyancy box is hollow, and the water quality detection probe is arranged through the bottom plate and the buoyancy box.

[0008] Optionally, a plurality of sets of limit rods are fixedly connected to the top of the buoyancy box, grooves are provided at positions corresponding to the limit rods on the bottom of the monitoring box body, limit blocks are installed in the grooves, the limit rods penetrate the limit blocks and are in sliding fit therewith, and a limit disk is fixedly connected to the top of the limit rods.

[0009] Optionally, both the first floating block and the second floating block are hollow.

[0010] Optionally, the second floating block is in a 冂-shaped configuration, sliding blocks are respectively fixedly connected to two sides of the second floating block, a sliding rod is slidably connected in the sliding block, positioning plates are respectively fixedly connected to two ends of the sliding rod, and the positioning plates are fixedly connected to the side surface of the monitoring box body.

[0011] Optionally, the positioning assembly includes a connecting seat fixedly connected to the bottom of the second floating block, the connecting seat is in a 冂-shaped configuration, a rotating shaft is fixedly connected in the connecting seat, a rotating rod is rotatably connected on the rotating shaft, a first sliding hole is provided at the middle position of the rotating rod, a fixed column is slidably connected in the first sliding hole, and the fixed column is fixedly connected to the side surface of the monitoring box body.

[0012] Optionally, a second sliding hole is provided at an end of the rotating rod away from the rotating shaft, a moving column is slidably connected in the second sliding hole, a moving block is fixedly connected to an end of the moving column close to the monitoring box body, a limit frame is slidably sleeved on the moving block, the moving block is prismatic, the limit frame is disposed on a side of the moving column close to the fixed column, and the limit frame is fixedly connected with the monitoring box body.

[0013] Optionally, a side plate is fixedly connected to a position corresponding to the moving block on the top of the buoyancy box, and a support block is fixedly connected to the side plate away from the monitoring box body.

[0014] Optionally, a handle is installed on the top of the monitoring box body.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: This invention achieves purely mechanical adaptive switching through the buoyancy of the water and the structure's own weight via the first float, the second float, and the buoyancy box. When the device enters the water, the buoyancy linkage positioning component automatically releases the limit, causing the bottom plate to float and the water quality detection probe to be exposed for normal detection. After the device exits the water, gravity automatically resets and locks the device, causing the water quality detection probe to be automatically stored between the monitoring box body and the bottom plate. The entire process requires no battery power and is unaffected by the device's power level, completely avoiding the problems of insufficient power, inability to retract the probe when power is off, and exposure damage in traditional devices. This greatly improves the protective stability and environmental adaptability of the device during outdoor operation. Furthermore, during the storage, handling, and transportation of the equipment, the probe can be stably maintained in its stored state through the coordination of the moving block, support block, and side plate limiting support. The bottom plate provides all-round anti-collision protection for the water quality detection probe, preventing bumps and scratches. In summary, this invention enables automatic exposure detection and storage protection of the probe without the need for electricity, significantly improving the reliability and stability of probe protection in field operations of portable water quality monitoring devices.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Figure 1 and Figure 3 As shown, this utility model proposes a portable water quality monitoring device, including a monitoring box body 1. A water quality detection probe 2 is fixedly connected to the bottom of the monitoring box body 1. The water quality detection probe 2 is used to monitor water quality. Both the monitoring box body 1 and the water quality detection probe 2 are existing technologies and will not be described in detail here. A handle 7 is installed on the top of the monitoring box body 1 for easy movement of this monitoring device.

[0022] Furthermore, the aforementioned detection device includes a base plate 3 disposed below the monitoring box body 1, which protects the water quality detection probe 2. A buoyancy box 31 is fixedly connected to the base plate 3. The buoyancy box 31 is hollow, allowing it to move upwards and closer to the monitoring box body 1 when the device is placed in water, due to its buoyancy. The water quality detection probe 2 passes through the base plate 3 and the buoyancy box 31, allowing it to be exposed after the base plate 3 and the buoyancy box 31 move upwards, thus enabling water quality monitoring. Multiple sets of limiting rods 32 are fixedly connected to the top of the buoyancy box 31. A groove 33 is provided at the bottom of the monitoring box body 1 corresponding to the limiting rods 32, with a limiting block 34 installed in the groove 33. The limiting rods 32 pass through the limiting blocks 34 and slide against them, ensuring smooth movement of both the buoyancy box 31 and the base plate 3. The top of the limiting rod 32 is fixedly connected to the limiting plate 35. The limiting plate 35 is used to limit the lowest position of the base plate 3 to prevent the base plate 3 from completely detaching from the monitoring box body 1.

[0023] Further, symmetrically arranged first floating blocks 4 are fixedly connected to both sides of the monitoring box body 1, and second floating blocks 5 are arranged on the other two sides of the monitoring box body 1. Both the first floating blocks 4 and the second floating blocks 5 are arranged in a hollow structure. The buoyancy generated by the first floating blocks 4 and the second floating blocks 5 after entering water enables the monitoring box body 1 to float on the water surface. The second floating block 5 is arranged in a 冂-shape, sliding blocks 51 are fixedly connected to both sides of the second floating block 5 respectively, a sliding rod 52 is slidably connected in the sliding block 51, and positioning plates 53 are fixedly connected to both ends of the sliding rod 52 respectively, the positioning plates 53 are fixedly connected to the side surface of the monitoring box body 1, and the arrangement of the sliding blocks 51 and the sliding rods 52 enables the second floating block 5 to move stably.

[0024] Specifically, please refer to Figures 1 to 3 , a positioning assembly 6 is arranged between the second floating block 5 and the bottom plate 3, and the positioning assembly 6 is used for positioning the bottom plate 3. The positioning assembly 6 comprises a connecting seat 61 fixedly connected to the bottom of the second floating block 5, and the connecting seat 61 is driven to move synchronously when the second floating block 5 moves. The connecting seat 61 is arranged in a 冂-shape, a rotating shaft 62 is fixedly connected in the connecting seat 61, and a rotating rod 63 is rotatably connected on the rotating shaft 62, so that one end of the rotating rod 63 rotates in the connecting seat 61 through the arrangement of the rotating shaft 62. A first sliding hole 64 is formed in the middle position of the rotating rod 63, a fixed column 65 is slidably connected in the first sliding hole 64, and the fixed column 65 is fixedly connected to the side surface of the monitoring box body 1. When the second floating block 5 moves upward or downward, it drives the rotating rod 63 to deflect, and meanwhile the fixed column 65 slides in the first sliding hole 64. A second sliding hole 66 is formed in an end of the rotating rod 63 away from the rotating shaft 62, a moving column 67 is slidably connected in the second sliding hole 66, a moving block 68 is fixedly connected to an end of the moving column 67 close to the monitoring box body 1, a limit frame 69 is slidably sleeved on the moving block 68, and the moving block 68 is arranged in a prismatic shape, so that the moving of the moving block 68 is stable, thereby the moving of the moving column 67 is stable. When the rotating rod 63 deflects, it drives the moving column 67 to move, and meanwhile the moving column 67 slides in the second sliding hole 66, so that the moving block 68 slides stably under the limiting effect of the limit frame 69. The limit frame 69 is arranged on a side of the moving column 67 close to the fixed column 65, and the limit frame 69 is fixedly connected with the monitoring box body 1, so that when the second floating block 5 moves upward, the moving block 68 moves toward a direction of the moving column 67 close to the fixed column 65, and when the second floating block 5 moves downward, the moving direction of the moving block 68 is opposite. A side plate 610 is fixedly connected at a position corresponding to the moving block 68 on the top of the buoyancy box 31, a supporting block 611 is fixedly connected to the side plate 610 away from the monitoring box body 1 when moving, and the side plate 610 and the supporting block 611 both move synchronously with the bottom plate 3.

[0025] It is worth mentioning that when this device is placed in water, the second float 5 moves upward due to buoyancy, and moves the moving block 68, causing the moving block 68 to move away from above the support block 611. At this time, because the buoyancy base plate 3 of the buoyancy box 31 moves upward and close to the monitoring box body 1, and the moving block 68 is on the side of the support block 611 and will not obstruct the upward movement of the side plate 610 and the support block 611, the water quality detection probe 2 is exposed and can be used for monitoring.

[0026] When the device is removed from the water, the second float 5 emerges first. Since the second float 5 has no buoyancy support, it moves downwards under gravity, causing the moving block 68 to move towards the fixed column 65, closer to the moving column 67. At this point, the end of the moving block 68 furthest from the limiting frame 69 contacts the side of the support block 611. When the bottom plate 3 emerges from the water, it also moves downwards under gravity. The support block 611 moves below the moving block 68, and then the second float 5 continues to move downwards under gravity, causing the moving block 68 to move to a position directly above the side plate 610. When the device is placed on the ground, the top of the side plate 610 contacts the moving block 68 for support, limiting the distance between the monitoring box body 1 and the bottom plate 3. The water quality detection probe 2 is located between the monitoring box body 1 and the bottom plate 3, and will not contact the ground, allowing for convenient placement and transportation. Simultaneously, the water quality detection probe 2, located in the middle of the bottom plate 3, is also protected from collision damage.

[0027] In this embodiment, when water quality monitoring is required, the entire device is placed in the water body to be tested. The entire device is buoyed by the first floats 4 on both sides of the monitoring box body 1 and the second floats 5 on the other two sides, ensuring the monitoring box body 1 floats stably on the water surface and guaranteeing the stability of the monitoring operation. After entering the water, the second floats 5 move upwards under the buoyancy of the water, and the sliders 51 on both sides of the second floats 5 slide smoothly vertically along the sliding rod 52. The movement is limited by the positioning plates 53 fixed at both ends of the sliding rod 52, ensuring that the second floats 5 rise and fall without deviation or jamming.

[0028] As the second float 5 moves upward, it drives the connecting seat 61 fixed at its bottom to move upward simultaneously. The rotating shaft 62 inside the connecting seat 61 is then lifted, pulling the rotating rod 63 to deflect around the rotating shaft 62. During the deflection of the rotating rod 63, the first sliding hole 64 at its middle position slides along the fixed column 65 fixed on the side of the monitoring box body 1, realizing the smooth deflection guidance of the rotating rod 63; at the same time, the second sliding hole 66 at the end of the rotating rod 63 slides relative to the moving column 67, pushing and pulling the moving column 67 and the moving block 68 at the end to move laterally, so that the moving block 68 slides smoothly along the limiting frame 69 fixed on the monitoring box body 1, and completely moves away from the support block 611, releasing the limiting obstruction on the side plate 610 and the support block 611.

[0029] After the limiting position of the moving block 68 is released, the base plate 3 below the monitoring box body 1 and the buoyancy box 31 fixed on the base plate 3 float upward under the buoyancy of the water. The multiple sets of limiting rods 32 on the top of the buoyancy box 31 slide vertically along the limiting blocks 34 inside the bottom groove 33 of the monitoring box body 1. Relying on the sliding cooperation between the limiting rods 32 and the limiting blocks 34, the base plate 3 and the buoyancy box 31 are ensured to move upward smoothly as a whole, avoiding displacement and shaking. At the same time, the limiting plate 35 on the top of the limiting rods 32 can effectively limit the maximum upward movement of the base plate 3, preventing structural dislocation. As the base plate 3 and the buoyancy box 31 move upward, the water quality detection probe 2 inserted inside them is fully exposed and in full contact with the water, thereby completing the real-time water quality monitoring operation.

[0030] Once the monitoring operation is completed and the device is removed from the water, the first float 4, the second float 5, and the buoyancy box 31 lose their buoyancy support. The second float 5 falls downward under its own weight, and then moves smoothly downward again through the cooperation of the slider 51 and the sliding rod 52. Simultaneously, it drives the connecting seat 61 to move downward, drives the rotating rod 63 to deflect in the opposite direction, and then pushes the moving column 67 and the moving block 68 to slide back to their original positions.

[0031] After the device is fully submerged, the bottom plate 3 and the buoyancy box 31 also fall downwards under their own weight, causing the side plate 610 and the support block 611 to move downwards simultaneously, so that the support block 611 gradually moves to a position below the moving block 68. As the second float 5 continues to move downwards, it eventually drives the moving block 68 to move precisely above the side plate 610 and the support block 611, forming a stable limiting support structure.

[0032] When the device is placed on the ground or transported, the moving block 68 supports and limits the lower support block 611, fixing the distance between the monitoring box body 1 and the base plate 3, so that the water quality detection probe 2 is completely housed within the space between the monitoring box body 1 and the base plate 3. The base plate 3 provides all-around protection for the water quality detection probe 2, preventing the probe from directly contacting the ground or external objects, and completely preventing bumps and scratches. At the same time, the handle 7 on the top of the monitoring box body 1 facilitates the overall handling and movement of the device by personnel, greatly improving the portability and protective reliability of the device.

[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
