Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensor protection, and more particularly to a protection device for sensors in flood monitoring stations. Background Art
[0002] In current hydrological monitoring technology, the sensor protection devices of flood monitoring stations face a major challenge. These sensors need to be installed in locations where they can accurately monitor water levels to ensure the accuracy and real-time nature of the data. However, since the water levels of rivers, lakes, or reservoirs are often low under normal circumstances, the sensors may be exposed to the air for a long time. This exposure not only makes the sensors vulnerable to erosion by natural factors such as sunlight, wind, rain, and dust, but may also be subject to human damage or animal interference, which seriously affects the service life of the sensors and the accuracy of data collection.
[0003] Traditional protective devices often adopt a fixed structure, and install the sensors at a low position to ensure that they can contact the water surface. However, this method has obvious defects. In the dry season or when the water level is extremely low, the sensors may still be completely exposed to the air and unable to perform their monitoring functions. At the same time, the fixed structure also limits the flexibility of the sensors to adjust their position with changes in water level, which may lead to the inability to respond in time when the water level rises sharply. This not only affects the reliability and safety of the monitoring system, but also may fail to provide key hydrological data in emergency situations, thereby increasing the difficulty and risk of flood prevention and control work.

[0015] (3) Beneficial effects
[0016] Compared with the prior art, the present invention provides a protective device for sensors in flood monitoring stations, which has the following beneficial effects:
[0017] 1. The beneficial effects of the mounting mechanism are reflected in many aspects. The protective cover can be slidably connected to the sensor body to provide basic protection for the sensor. The transverse hole and transverse rod form a flexible adjustment mechanism. The annular groove and transverse rod cooperate to provide a stable fixing point. The follower frame increases structural flexibility. The release ball and release sleeve facilitate installation and removal.

This design allows the operator to unlock quickly and accurately without the need for complex tools. Pushing the unlocking sleeve can achieve external expansion of the follower frame, easily releasing the fixation and completing the unlocking process. The efficient unlocking mechanism saves maintenance time and reduces operational risks. It is particularly suitable for scenarios that require frequent inspections or emergency situations.

The mounting mechanism includes a protective sleeve 2, a tail pipe 3, a transverse rod 4, a follower frame 5, an unfastening ball 6, an unfastening sleeve 7, a fixing mechanism, and an unfastening mechanism. The protective sleeve is slidably connected to the sensor body 1. The tail pipe 3 is mounted on the protective sleeve. A plurality of transverse holes 8 are evenly spaced on the side wall of the protective sleeve. A transverse rod 4 is slidably connected in each transverse hole 8. A plurality of annular grooves 9 are provided on the side wall of the sensor body 1. The transverse rod 4 is inserted into the annular groove 9. A follower frame 5 is mounted on each two transverse rods 4. There are two unhooking balls 6, and the unhooking sleeve 7 is slidably connected to the protective sleeve. The fixing mechanism and the unhooking mechanism are respectively installed on the protective sleeve. The fixing mechanism includes a receiving spring 10 and a reinforcement sleeve 11. There are multiple receiving springs 10, and multiple receiving springs 10 are respectively installed on the follower frame 5. Each receiving spring 10 is respectively installed with multiple reinforcement sleeves 1. An adjusting sleeve 12 is threaded on the protective sleeve, and a follower groove 13 is provided on the adjusting sleeve 12. The follower ring 101 is rotatably connected in the follower groove 13. The follower ring 101 is provided with multiple push rods 14 at equal intervals. The push rods 14 are inserted into the receiving spring 10. Tension springs 15 are respectively provided on the inner walls of the multiple follower frames 5, and the multiple tension springs 15 are respectively installed on the side walls of the protective sleeve.
[0030] After the cam 14 is in the closed position, the push rod 14 is pushed in and the push rod 14 is pushed in and out of the protective sleeve 2.
[0031] See also Figures 2 to 5 , as an implementation method of a protective device for a flood monitoring station sensor of an untying mechanism: the untying mechanism includes a reducing sleeve 16, a plurality of reducing sleeves 16 are provided, and the plurality of reducing sleeves 16 are equidistantly installed on the untying sleeve 7, the reducing sleeve 16 is fitted on the side wall of the protective sleeve, and an expansion groove 17 is provided on both sides of each reducing sleeve 16, the untying ball 6 is slidably connected to the expansion groove 17, and two reducing grooves 18 are equidistantly provided on the side walls of the plurality of reducing sleeves 16, the untying ball 6 is stuck in the reducing groove 18, and a limit ring 19 is coaxially provided on the lower end surface of the protective sleeve 2.
[0032] More specifically, when it is necessary to unlock, the unlocking sleeve 7 is pushed upward, the reducing sleeve 16 abuts against the follower frame 5, and the unlocking sleeve 7 abuts against the reducing groove 18, so that the follower frame 5 can be expanded outward synchronously, and then the transverse rod 4 is unlocked and fixed with the annular groove 9, thereby unlocking the connection between the two and completing the unlocking process.
[0033] In summary, when the entire device is in use or running: when protecting the sensor body 1, first slide the protective sleeve 2 onto the sensor body 1, then push the release sleeve 7 so that the release ball 6 is stuck in the variable diameter groove 18, and then the follower frame 5 will expand outward, and the transverse rods 4 will slide into the transverse holes 8 respectively. At this time, the protective sleeve 2 can be slid along the sensor body 1 so that the sensor body 1 fits on the limit ring 19, and then release the release sleeve 7. Under the action of the tension spring 15, the transverse rod 4 is inserted into the annular groove 9. At this time, the protective sleeve 2 and the sensor body 1 are in a synchronously fixed state, and then the adjusting sleeve 12 is rotated. Since the adjusting sleeve 12 The threaded connection is on the outer wall of the protective sleeve 2, so it will drive the push rod 14 to slide downward, and the push rod 14 is inserted into the reinforcement sleeve 11, and then the fixation of the follower frame 5 is ensured, thereby completing the fixed state. At this time, the protective sleeve 2 and the sensor body 1 are in a fixed state, so it has an effective protective effect on the sensor body 1. When it needs to be unlocked, the follower pushes the unlocking sleeve 7 upward, the reducing sleeve 16 abuts on the follower frame 5, and the unlocking sleeve 7 abuts on the reducing groove 18, so the follower frame 5 can be expanded outward synchronously, and then the transverse rod 4 is unlocked and fixed to the annular groove 9, thereby unlocking the connection between the two, and then completing the unlocking process.
