Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology and relates to an environmental monitoring device, specifically a telescopic and foldable environmental monitoring probe structure. Background Technology

[0002] Environmental monitoring probes come in various forms. In the field of water pollution monitoring equipment, water quality sensors are widely used. These sensors can provide real-time or periodic data on water quality parameters, helping us assess the health of water bodies, prevent water pollution incidents, and guide adjustments to water treatment processes. A water quality sensor is a device that can monitor the content or properties of specific substances in water. It can provide real-time or periodic data on water quality parameters, including but not limited to pH, dissolved oxygen, turbidity, conductivity, heavy metal ion concentration, and organic pollutants. This data is crucial for assessing the health of water bodies, preventing water pollution incidents, and guiding adjustments to water treatment processes. Water quality monitoring sensors can be categorized into physical parameter sensors, chemical parameter sensors, and biological parameter sensors based on the monitored indicators.

[0003] 1. Physical parameter sensor: used to measure physical properties such as water temperature, turbidity, and conductivity.

[0004] 2. Chemical parameter sensor: used to monitor chemical properties such as pH value, dissolved oxygen, ammonia nitrogen, residual chlorine, chemical oxygen demand (COD), and biochemical oxygen demand (BOD).

[0005] 3. Bioparameter sensors: These sensors utilize biological reactions to monitor microorganisms or organic pollutants in water, such as assessing the concentration of organic pollutants in water through the respiratory activity of microorganisms.

[0006] When water pollution monitoring probes (water quality sensors) are used in practice, especially when testing the water quality in one location, the sensor end is directly exposed when moving the cable to another location where water quality needs to be tested. Many water quality sensors have delicate structures at their sensor ends, including but not limited to the glass bulb of the pH electrode, the thin-film probe of the dissolved oxygen (DO) electrode, and the sensitive membrane of the ion selective electrode (ISE). Taking the glass bulb of the pH electrode as an example, it is only a few millimeters in diameter and is brittle. It is very easy to break when it hits hard objects such as rocks, metal railings, and ship hulls, which can lead to electrolyte leakage and measurement failure. Utility Model Content

[0007] The purpose of this invention is to provide a telescopic and foldable environmental monitoring probe structure to solve the defects mentioned in the background art.

[0008] To achieve the above objectives, a telescopic and foldable environmental monitoring probe structure is provided, including a telescopic linkage mechanism. A folding arm mechanism is located at the bottom of the telescopic linkage mechanism, and a lower protective shell is mounted on the folding arm mechanism. An upper protective shell is mounted on one side of the lower protective shell. A drive shaft is movably mounted on the upper protective shell via a bearing. An internal gear is movably mounted on the upper protective shell, and a transmission rack is mounted on one side of the internal gear. A drive seat is fixedly mounted on the top of the transmission rack, and a screw is mounted on the drive seat. A drive shaft is mounted on the top of the screw. A transverse connecting rod is fixedly mounted at one end of the transmission rack, and a positioning plate is fixedly mounted at the end of the transmission rack away from the transverse connecting rod. A multi-parameter monitoring probe is mounted at the bottom of the positioning plate, and the multi-parameter monitoring probe is located inside the lower protective shell.

[0009] Preferably, the folding arm mechanism includes a drive arm, a blocking cover, and a sector gear. The drive arm is fixedly mounted on the end of the sector gear, and the blocking cover is fixedly mounted on the end of the drive arm. Multiple sets of perforations are evenly opened on the blocking cover.

[0010] Preferably, the blocking cover covers the opening at the bottom of the lower protective shell, and the blocking cover rotates about the axis of the sector gear.

[0011] Preferably, an external incomplete gear is installed on one side of the sector gear. The sector gear is movably connected to the outside of the lower housing through a bearing seat. The sizes of the sector gear and the external incomplete gear are matched, and the sector gear and the external incomplete gear are meshed together.

[0012] Preferably, the telescopic linkage mechanism includes a drive shaft, a drive seat, a screw, a mounting seat, a positioning plate, a multi-parameter monitoring probe, a transverse link, a limit rod, a transmission rack, an internal gear, and an external incomplete gear; the shaft end of the external incomplete gear is fixedly provided with an internal gear, and a transmission rack is installed on one side of the internal gear.

[0013] Preferably, the internal gear and the transmission rack are matched in size and mesh with each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the multi-parameter monitoring probe can be retracted into the lower protective shell in the above manner. The lower and upper protective shells provide anti-collision protection for the moving parameter monitoring probe, which can effectively resist external impacts such as collisions, squeezing, and falls, and prevent the probe from failing due to mechanical damage to internal components such as sensors and circuit modules. The enclosing design of the lower and upper protective shells can reduce the direct contact between the probe and external objects during movement, and reduce the risk of accidental damage.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a telescopic and foldable environmental monitoring probe structure, including a telescopic linkage mechanism 4, a folding arm mechanism 3 at the bottom of the telescopic linkage mechanism 4, a lower protective shell 2 on the folding arm mechanism 3, an upper protective shell 1 on one side of the lower protective shell 2, a drive shaft 41 movably mounted on the upper protective shell 1 via a bearing, an internal gear 49 movably mounted on the upper protective shell 1, a transmission rack 48 mounted on one side of the internal gear 49, a drive seat 42 fixedly mounted on the top of the transmission rack 48, a screw 43 mounted on the drive seat 42, a drive shaft 41 mounted on the top of the screw 43, a transverse connecting rod 47 fixedly mounted at one end of the transmission rack 48, a positioning piece 45 fixedly mounted at the end of the transmission rack 48 away from the transverse connecting rod 47, a multi-parameter monitoring probe 46 mounted at the bottom of the positioning piece 45, and the multi-parameter monitoring probe 46 being located inside the lower protective shell 2.

[0025] Working principle: In practical applications, the equipment installed at the end of the drive shaft 41 includes, but is not limited to, a manual rotating wheel and a waterproof motor. The manual rotating wheel facilitates manual rotation of the drive shaft 41; the waterproof motor facilitates automatic rotation of the drive shaft 41. The manual rotating wheel or the waterproof motor is not shown in the figure.

[0026] When the multi-parameter monitoring probe 46 needs to be used, the screw 43 is rotated by rotating the drive shaft 41. When the screw 43 rotates, it drives the drive seat 42 on its outer side to move downward. The drive seat 42 drives the multi-parameter monitoring probe 46 to move downward through the transmission rack 48 and the positioning plate 45. At the same time, when the transmission rack 48 moves downward, it drives the internal gear 49 to rotate. At the same time, the external incomplete gear 491 rotates. The external incomplete gear 491 meshes with the sector gear 33, so that the sector gear 33 drives the blocking cover 32 to rotate through the drive arm 31. The blocking cover 32 is disengaged from the bottom of the lower protective shell 2, and the multi-parameter monitoring probe 46 is disengaged from the inside of the lower protective shell 2, so that the multi-parameter monitoring probe 46 can be used to perform multi-parameter water quality monitoring of the target water body.

[0027] When the multi-parameter monitoring probe 46 is not in use, it can be retracted into the lower housing 2 in the manner described above. The lower housing 2 and the upper housing 1 provide anti-collision protection for the moving probe 46, effectively resisting external impacts such as collisions, squeezing, and falls, and preventing mechanical damage to the probe from causing failure of internal components such as sensors and circuit modules. The enclosing design of the lower housing 2 and the upper housing 1 reduces direct contact between the probe and external objects during movement, lowering the risk of accidental damage.

[0028] In actual use, this multi-parameter monitoring probe 46 can be adapted to two different sets of usage conditions: the first is still water flow water quality detection, and the second is flowing water flow water quality detection. Specifically, when the multi-parameter monitoring probe 46 is detached from the bottom of the lower protective shell 2, the multi-parameter monitoring probe 46 can perform water quality monitoring on still water flow.

[0029] When it is necessary to monitor the water quality of flowing water areas such as industrial wastewater discharge outlets and estuaries, the design of the upper protective shell 1, lower protective shell 2 and blocking cover 32, along with the mesh panel at the front of the upper protective shell 1 and lower protective shell 2, can resist the impact of floating objects in the water, such as the impact of waves generated by ship navigation, and ensure that the probe works stably in water bodies with high flow velocity or high impurities.

The drive arm 31 is fixedly disposed at the end of the sector gear 33, and the blocking cover 32 is fixedly disposed at the end of the drive arm 31. Multiple sets of perforations are evenly opened on the blocking cover 32.

[0031] In a preferred embodiment, the blocking cover 32 covers the opening at the bottom of the lower housing 2, and the blocking cover 32 rotates about the axis of the sector gear 33.

[0032] In a preferred embodiment, an external incomplete gear 491 is installed on one side of the sector gear 33. The sector gear 33 is movably connected to the outside of the lower housing 2 through a bearing seat. The sizes of the sector gear 33 and the external incomplete gear 491 are matched, and the sector gear 33 and the external incomplete gear 491 are meshed together.

[0033] In a preferred embodiment, the telescopic linkage mechanism 4 includes a drive shaft 41, a drive seat 42, a screw 43, a mounting seat 44, a positioning plate 45, a multi-parameter monitoring probe 46, a transverse link 47, a limit rod 471, a transmission rack 48, an internal gear 49, and an external incomplete gear 491; the internal gear 49 is fixedly provided at the end of the shaft of the external incomplete gear 491, and the transmission rack 48 is installed on one side of the internal gear 49.

[0034] In a preferred embodiment, the internal gear 49 and the transmission rack 48 are matched in size and mesh with each other. The bottom of the screw 43 on one side of the transmission rack 48 is movably supported by the mounting base 44. Two sets of guide rods 441 are installed on the mounting base 44, and the two sets of guide rods 441 are respectively inserted into the guide holes opened on both sides of the bottom of the positioning piece 45.

[0035] In a preferred embodiment, the transverse connecting rod 47 and the transmission rack 48 are arranged in an "L" shape. A limiting hole is provided at the end of the transverse connecting rod 47, and a limiting rod 471 is inserted into the limiting hole. One end of the limiting rod 471 is fixed to the inner wall of the upper protective shell 1, and the other end of the limiting rod 471 is fixed to the inner wall of the lower protective shell 2.
