[0032] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model; obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, and all other embodiments obtained by the ordinary skilled in the art without creative labor based on the embodiments in the utility model belong to the protection scope of the utility model.

[0033] Embodiment:

[0034] Please refer to Figure 1 - Figure 4The invention discloses an abrasion-proof device for water level measurement of inland waterway, which comprises a sounding rod 1, a hollow box 2 fixedly installed at the bottom end of the sounding rod 1 through bolts, a movable ball 3 movably connected to the side bottom end of the sounding rod 1 through a bearing sleeve, two tail wings 301 fixedly installed on the side of the movable ball 3, a protective net structure 4 sleeved between the side bottom and the side top of the sounding rod 1, and a flow divider cover 5 arranged outside the protective net structure 4.

[0035] The protective net structure 4 is composed of an upper ring sleeve 401, a lower ring sleeve 402, a plurality of intermediate ring sleeves 403 and a plurality of protective wire meshes 404.

[0036] Referring to Figure 1 Specifically, the hollow box 2 is composed of two parallel metal plates which are fixedly connected through bolts.

[0037] The distance between the two metal plates can be adjusted by adjusting the position of the nut in the bolt.

[0038] Specifically, the hollow box 2 is a semi-closed cage structure, and the bottom plate of the hollow box 2 is made of magnetic iron material.

[0039] The magnetic iron material can adsorb some metal blocks, and the metal blocks can be used as counterweights to improve the stability of the sinking of the sounding rod 1.

[0040] Specifically, the two tail wings 301 are spread in an outward eight-character shape, and the included angle between the two tail wings 301 is 60°.

[0041] The tail wings 301 are placed in water, and the flow of water drives the tail wings 301 to move, thereby facilitating the judgment of the direction of the water flow.

[0042] Referring to Figure 1 , Figure 3 Specifically, the distance between any two intermediate ring sleeves 403 is equal, and the protective wire mesh 404 is a ring-shaped mesh structure.

[0043] The ring-shaped mesh structure can prevent the mud and water plants in the water from directly impacting the sounding rod 1, and at the same time, the water flow can pass through the gap of the protective wire mesh 404 without affecting the measurement of water depth.

[0044] Referring to Figure 1 , Figure 2 , Figure 3 Specifically, the side of the upper ring sleeve 401 and the side of the lower ring sleeve 402 are fixedly installed with chucks 405, the end of the flow divider cover 5 is clamped with the chucks 405 through the clamping seat 501, and the clamping seat 501 is fixed through bolts.

[0045] In this way, the installation of the flow distributor 5 can be facilitated by the clamping alignment of the clamping seat 501 and the chuck 405.

[0046] Referring to Figure 1 , Figure 4 Specifically, the cross section of the flow distributor 5 is triangular, and the length of the flow distributor 5 is greater than the length of the entire protective net structure 4.

[0047] The triangular structure can facilitate the disturbance of the water flow, so as to avoid the direct impact of the water flow on the depth probe 1 and cause abrasion. The length of the flow distributor 5 can effectively protect the protective net structure 4 and the depth probe 1 inside.

[0048] Working principle:

[0049] The flow distributor 5 is fixed on the side of the protective net structure 4 by the clamping alignment of the clamping seat 501 and the chuck 405. If the water flow speed is too fast, the counterweight can be placed in the hollow box 2.

[0050] Then, the bottom end of the depth probe 1 is slowly immersed in water. The direction of the water flow is determined by the rotation of the movable ball 3 and the orientation of the tail wing 301. It is ensured that the extension direction of the tail wing 301 is consistent with the flow direction of the water flow, and the flow distributor 5 is in the upstream direction of the water flow. In this way, the flow distributor 5 can facilitate the disturbance of the water flow, so as to avoid the direct impact of the water flow on the depth probe 1 and cause abrasion.

[0051] Then, the depth probe 1 is continuously inserted, the water flow passes through the gap of the protective wire mesh 404, and the measurement of the water depth is completed.

[0052] The above describes only the preferred specific embodiments of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme of the present application and the improved concept thereof, can make equivalent replacements or changes within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
