Description

Technical Field

[0001] The utility model relates to the field of hydrological monitoring, in particular to a probe protection device for monitoring water levels. Background Art

[0002] Hydrological monitoring systems are used by hydrological departments to monitor hydrological parameters such as rivers, lakes, reservoirs, channels, and groundwater in real time. Monitoring includes water level, flow, flow velocity, rainfall (snow), evaporation, sediment, ice, soil moisture, and water quality. Water level monitoring stations are important hydrological monitoring facilities, primarily used for real-time, continuous monitoring of water levels in rivers, lakes, reservoirs, and other water bodies, providing a scientific basis for flood control, drought relief, and water resource management. Water level monitoring stations primarily use water level probes as data acquisition devices to monitor hydrological data in real time. To ensure stable operation of water level probes in river channels, water level monitoring stations must protect them from damage caused by floating debris. Furthermore, in rivers with high flow rates, the impact of sediment on the probes must be minimized to ensure smooth operation and a long service life. Utility Model Content

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] Example:

[0047] like Figures 1 to 6 As shown, a probe protection device for monitoring water level includes:

[0048] The protective seat 1 is stably arranged in the water area to be monitored, and has a receiving groove 131 with an upward opening on the top;

[0049] The sealing plate 2 is provided on the top of the protective seat 1 to shield the receiving groove 131;

[0050] The probe placement tube 3 is horizontally inserted into the protective base 1, with the tail end flush with the outer surface of the protective base 1 and the head end located in the accommodating groove 131;

[0051] The water inlet pipe is horizontally installed in the protective base 1, with the tail end flush with the outer surface of the protective base 1 and the head end located in the accommodating groove 131; the lowest water level of the water inlet pipe is not higher than the highest water level of the probe placement tube 3; the axis of the water inlet pipe is perpendicular to the flow direction of the water body to be monitored;

[0052] The sand guide pipe is provided in the middle portion thereof within the protective seat 1, with the head and tail ends not exceeding the outer surface of the protective seat 1. The inner cavity of the sand guide pipe is connected to the bottom of the accommodating groove 131; the axis of the sand guide pipe is parallel to the flow direction of the water body to be monitored;

[0053] The trash rack 6 is arranged outside the protection base 1 to shield the tail end of the water inlet pipe and the head end of the sand guide pipe.

[0054] The protective seat 1 and the sealing plate 2 form a relatively closed space, which can better protect the water level probe 7 and prevent it from being impacted by large-sized objects or hard objects in the water body. The water inlet pipe can ensure that the water in the water body can flow smoothly into the storage tank 131, so that the liquid level of the water body contacted by the water level probe 7 is consistent with the liquid level outside the protective seat 1. The axis of the water inlet pipe is perpendicular to the flow direction of the water body, which can reduce the probability of impurities in the water body entering the storage tank 131, and at the same time reduce the impact of more water entering the storage tank 131 due to the impact of the water flow, resulting in the water level in the storage tank 131 becoming higher, making the water body probe inaccurate detection, and can also reduce the impact of the impact pressure generated by the water body entering the storage tank 131 through the water inlet pipe on the detection results of the water level probe 7. The sand guide pipe can discharge the mud and sand deposited at the bottom of the storage tank 131 out of the storage tank 131 when the water flow is large, reducing the frequency of cleaning the storage tank 131. The trash rack 6 can prevent larger impurities in the water from entering the accommodating tank 131 through the sand guide pipe and the water inlet pipe.

[0058] The bend 42 can prevent the water from flowing obliquely or vertically into the water inlet pipe and causing an impact on the water level probe 7. At the same time, it can prevent hard objects or other large-sized impurities from directly hitting the water level probe 7 when the trash rack 6 is damaged. At the same time, the water outlet 421 can ensure that the water entering from the water inlet pipe can be quickly dispersed into the accommodating cavity.

[0059] In this embodiment, a bottom groove 132 is provided at the bottom of the accommodating groove 131; the outline size of the bottom groove 132 is smaller than the bottom of the accommodating groove 131; a grate 133 is provided at the bottom of the accommodating groove 131 to shield the bottom groove 132; the bottom groove 132 is connected to the inner cavity of the sand guide pipe.
