Description

Technical Field

[0001] This utility model relates to a clinometer protection device for earth-rock dams, belonging to the field of earth-rock dam safety monitoring technology. Background Technology

[0002] During the construction of earth-rock dams, it is usually necessary to bury inclinometer tubes to protect the inclinometers and sensing optical cables placed inside. However, due to the influence of construction machinery and equipment and the environment, dust, stones, and rainwater inevitably enter the inclinometer tubes. When the inclinometer tubes are buried at a shallow depth, compressed air can be used to blow out the stones and dust that have fallen into the bottom of the inclinometer tubes, but this process is time-consuming and ineffective. When the inclinometer tubes are buried at a deep depth, with a length that can reach tens or even hundreds of meters, it is impossible to remove the dust and stones from the bottom of the inclinometer tubes.

[0003] Chinese patent document CN212843531U discloses a protective device for an electromagnetic settling meter, including a protective cap and a protective inner liner. The protective cap has a connecting ring inside, and the protective inner liner has a connecting rod. The connecting ring and the connecting rod are connected by a connecting rope. The protective inner liner is positioned inside the electromagnetic settling meter, and the protective cap is fixed to the limiting side edge of the electromagnetic settling meter. This double-layered cap and inner liner structure provides protection at the top of the electromagnetic settling meter, preventing debris from entering and reducing the possibility of damage.

[0004] However, when using the above-mentioned device to clean the dust and stones inside the inclinometer tube, because the outer shell of the electromagnetic settling device is made of hard material, a lot of dust and small stones will fall to the bottom of the inclinometer tube through the gap between the outer shell of the electromagnetic settling device and the inner wall of the inclinometer tube. Therefore, the cleaning effect of the above-mentioned device on dust and stones still needs to be further improved. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a protection device for inclinometer tubes used in earth-rock dams.

[0006] This utility model is achieved through the following technical solution:

[0007] A protective device for a clinometer tube used in earth-rock dams includes a tube opening protective cover, a flexible connection component, an elastic cleaning component, and a lifting block. The elastic cleaning component is cylindrical, and its outer diameter is not less than the inner diameter of the clinometer tube. The elastic cleaning component is mounted on the lifting block. One end of the flexible connection component is connected to the tube opening protective cover, and the other end passes through the elastic cleaning component and is connected to the lifting block.

[0008] The lifting block includes a galvanized steel pipe and a circular end cap plate located at the upper end of the galvanized steel pipe. A cross-shaped hanger is provided inside the galvanized steel pipe, and a threaded hole is coaxially provided on the circular end cap plate.

[0009] The outer diameter of the galvanized steel pipe is the same as the outer diameter of the circular end cap, and the outer diameter of the galvanized steel pipe is smaller than the inner diameter of the inclinometer tube.

[0010] The elastic cleaning component includes a cylindrical sponge block, a gasket, and an external hexagonal hollow bolt. The cylindrical sponge block has a coaxial circular hole. The gasket is located on the upper side of the cylindrical sponge block. The lower end of the external hexagonal hollow bolt passes through the gasket and the circular hole and is connected to the lifting block.

[0011] The cylindrical sponge block is fitted with the inclinometer tube via a transition fit or an interference fit.

[0012] One end of the flexible connection component is connected to the pipe opening protective cover via a lifting ring.

[0013] The flexible connection component is a steel wire rope.

[0014] The outer side of the wire rope is wrapped with rubber tape, and one end of the rubber tape is connected to the pipe end protective cap, and the other end is connected to the lifting block.

[0015] The beneficial effects of this utility model are as follows: the upper end of the inclinometer tube is sealed by the pipe opening protection cap to prevent rainwater, dust, and stones from falling into the inclinometer tube through the upper end of the pipe opening; during the construction of earth-rock dams, if the wall of the inclinometer tube is damaged due to construction machinery and equipment, resulting in some dust and stones entering the inclinometer tube, the elastic cleaning component intercepts the dust, stones, and other debris that have entered the inclinometer tube. Then, the elastic cleaning component and the lifting block can be pulled out from the upper end of the inclinometer tube using the pipe opening protection cap and the flexible connecting component. Since the outer diameter of the elastic cleaning component is not less than the inner diameter of the inclinometer tube, it can improve its cleaning effect on dust and stones inside the inclinometer tube.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] like Figs. 1 to 3 As shown, the present invention discloses a protective device for a clinometer tube used in earth-rock dams, comprising a tube opening protective cap 1, a flexible connecting assembly, an elastic cleaning assembly, and a lifting block 8. The elastic cleaning assembly is cylindrical, and its outer diameter is not less than the inner diameter of the clinometer tube 9. The elastic cleaning assembly is mounted on the lifting block 8. One end of the flexible connecting assembly is connected to the tube opening protective cap 1, and the other end passes through the elastic cleaning assembly and connects to the lifting block 8. In use, the lifting block 8 and the elastic cleaning assembly are placed into the clinometer tube 9. Under the weight of the lifting block 8, the lifting block 8 and the elastic cleaning assembly overcome the friction between the elastic cleaning assembly and the clinometer tube 9 and slide down together to the bottom of the clinometer tube 9. Then, the tube opening protective cap 1 is placed over the upper opening of the clinometer tube 9. The upper end of the inclinometer tube 9 is sealed by the pipe opening protection cap 1 to prevent rainwater, dust, and stones from falling into the inclinometer tube 9 through the upper end. During the construction of the earth-rock dam, if the wall of the inclinometer tube 9 is damaged due to construction machinery and equipment, causing some dust and stones to enter the inclinometer tube 9, the elastic cleaning component will intercept the dust, stones, and other debris that have entered the inclinometer tube 9. Then, the elastic cleaning component and the lifting block 8 can be pulled out from the upper end of the inclinometer tube 9 using the pipe opening protection cap 1 and the flexible connection component. Since the outer diameter of the elastic cleaning component is not less than the inner diameter of the inclinometer tube 9, it can improve the cleaning effect on the dust and stones inside the inclinometer tube 9.

[0022] The lifting block 8 includes a galvanized steel pipe and a circular end cap plate located at the upper end of the galvanized steel pipe. A cross-shaped hanger is installed inside the galvanized steel pipe, and a threaded hole is coaxially provided on the circular end cap plate. In use, one end of the steel wire rope 4 and the rubber band 3 are tied to the cross-shaped hanger inside the galvanized steel pipe. The threaded hole on the circular end cap plate is used for threaded connection with the external hexagonal hollow bolt 5.

[0023] The outer diameter of the galvanized steel pipe is the same as the outer diameter of the circular end cap, and the outer diameter of the galvanized steel pipe is smaller than the inner diameter of the inclinometer tube 9. This smaller outer diameter ensures that the galvanized steel pipe can move freely within the inclinometer tube 9.

[0024] The elastic cleaning assembly includes a cylindrical sponge block 7, a washer 6, and a hollow hexagonal bolt 5. The cylindrical sponge block 7 has a coaxial circular hole. The washer 6 is located on the upper side of the cylindrical sponge block 7. The lower end of the hollow hexagonal bolt 5 passes through the washer 6 and the circular hole and connects to the lifting block 8. In use, the hollow hexagonal bolt 5 refers to a bolt formed by coaxially creating a through hole in a standard hexagonal bolt. The lower end of the hollow hexagonal bolt 5 passes through the washer 6 and the circular hole and is threadedly connected to a threaded hole on the circular end cap plate. The cylindrical sponge block 7 is installed and fixed to the circular end cap plate by the hollow hexagonal bolt 5 and the washer 6.

[0025] The cylindrical sponge block 7 is fitted with the inclinometer tube 9 in a transition fit or an interference fit.

[0026] One end of the flexible connection component is connected to the pipe opening protective cover 1 via a lifting ring 2.

[0027] The flexible connection component is steel wire rope 4.

[0028] The outer side of the wire rope 4 is wrapped with rubber tape 3, and one end of the rubber tape 3 is connected to the pipe end protective cover 1, and the other end is connected to the lifting block 8. In use, one end of the wire rope 4 and the rubber tape 3 is connected to the lifting ring 2 inside the pipe end protective cover 1, and the other end passes through the through hole on the external hexagonal hollow bolt 5 and is tied to the cross-shaped hanger inside the galvanized steel pipe.
