Technical Field

[0001] This utility model relates to the field of manhole equipment, and in particular to a sealed high-pressure reinforced concrete waterway top manhole device. Background Technology

[0002] The sealed high-pressure concrete waterway is used to transport high-pressure water in projects such as wave generation. The waterway requires regular cleaning and maintenance. Manholes are installed at the top of the waterway to allow personnel and equipment access. However, leakage is likely to occur in the high-pressure water flow under manned access. The manhole covers are complex to open and close, posing low safety risks. Furthermore, they slow down the entry of personnel and equipment into the concrete waterway during maintenance, thus impacting work efficiency. Summary of the Invention

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A sealed high-pressure reinforced concrete waterway top manhole device includes a manhole structure main component, a manhole cover assembly, a sealing cover assembly, and a manhole cover assembly removal device. The manhole structure main component is installed on the outer top surface of a pre-reserved hole in the reinforced concrete waterway, and the sealing cover assembly is installed on the inner top surface of the pre-reserved hole. The manhole structure main component and the sealing cover assembly are connected and locked together by double-ended studs. A manhole structure main component flange is provided at the manhole of the manhole structure main component, and the manhole structure main component flange is connected to the manhole cover assembly by bolts. The manhole cover assembly removal device is connected to one side of the manhole structure main component via a pad. The top of the manhole cover assembly removal device is connected to a swing arm, and the end of the swing arm is connected to a sleeve with a screw threaded through it. A threaded sleeve is connected to the middle of the top surface of the manhole cover assembly, and the screw is threaded into the threaded sleeve. An exhaust valve is connected to the manhole cover assembly, and a valve is connected to the exhaust valve.

[0006] The manhole cover assembly removal device includes a shaft cylinder and a shaft. A bearing is installed at each of the upper and lower ends of the shaft cylinder, and the shaft is rotatably connected to the shaft cylinder through the bearings.

[0007] The shaft is fastened to the pad by bolts.

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A sealed high-pressure reinforced concrete waterway top manhole device includes a manhole structure main component 1, a manhole cover assembly 9, a sealing cover assembly 19, and a manhole cover assembly removal device 4. The manhole structure main component 1 is installed on the outer top surface of a pre-reserved hole in the reinforced concrete waterway, and the sealing cover assembly 19 is installed on the inner top surface of the pre-reserved hole in the reinforced concrete waterway. The manhole structure main component 1 and the sealing cover assembly 19 are connected and locked by double-ended studs 16. A manhole structure main component flange 2 is provided at the manhole of the manhole structure main component 1. The flange 2 is locked to the manhole cover assembly 9 by bolts 7. The main body of the manhole structure 1 is connected to the manhole cover assembly 9 by a pad 3 on one side. The top of the manhole cover assembly 9 removal device 4 is connected to a swing arm 6. The end of the swing arm 6 is connected to a sleeve 11. A screw 10 is inserted into the sleeve 11. A threaded sleeve 12 is connected to the middle of the top surface of the manhole cover assembly 9. The screw 10 is threaded into the threaded sleeve 12. An exhaust valve 14 is connected to the manhole cover assembly 9. A valve 15 is connected to the exhaust valve 14.

[0021] The manhole cover assembly removal device 4 includes a shaft cylinder 41 and a shaft 5. A bearing 42 is installed at each of the upper and lower ends of the shaft cylinder 41. The shaft 5 is rotatably connected to the shaft cylinder 41 through the bearings 42. The bearings 42 enable the shaft 5 to rotate freely with the swing arm 6, improving the flexibility of adjusting the position of the swing arm 6.

[0022] The shaft cylinder 41 is fastened to the pad 3 by bolts. The pad 3 is connected to the main body of the manhole structure 1 to ensure that the manhole cover assembly removal device 4 is fixed and stable.

[0023] The manhole cover assembly 9 has handles 13 fixed on both sides of the threaded sleeve 12, which facilitates manual adjustment of the position of the manhole cover assembly 9 by controlling the handles 13.

[0024] A sealing gasket 18 is installed between the sealing cover plate assembly 19 and the top surface of the reserved hole in the reinforced concrete waterway; a sealing ring is installed at the joint surface between the main body of the manhole structure 1 and the manhole cover plate assembly 9. The setting of the sealing gasket 18 and the sealing ring ensures that the manhole device as a whole does not leak under high pressure water flow conditions in the sealed high pressure reinforced concrete waterway.

[0025] The sealing cover assembly 19 has a reinforcing frame 17 installed near the inner top surface inside the reserved hole of the reinforced concrete waterway.

[0026] A washer 8 is provided between the nut of the screw 10 and the sleeve 11.

[0027] When personnel and equipment need to enter the waterway for cleaning and maintenance, the following operations should be performed: Remove the manhole cover assembly 9 from the flange 2 of the main manhole structure, which is connected by bolts 7. Tighten screws 10 into the threaded sleeves 12 to separate the plane of the manhole cover assembly 9 from the plane of the flange 2 of the main manhole structure. Then, push the swing arm 6 to rotate 180° so that the manhole cover assembly 9 reaches the desired position. Figure 2 The location shown.

[0028] After personnel and equipment enter the waterway through the manhole to complete their work, they withdraw from the manhole. Then, the swing arm 6 is pushed to rotate 180° so that the manhole cover assembly 9 returns to the flange 2 of the main body of the manhole structure. Align the connecting holes, loosen the screws 10, separate the screws 10 from the threaded sleeves 12, and tighten the connecting holes with bolts 7. That is, after personnel and equipment withdraw from the waterway, the manhole cover assembly 9 is restored to the state of being connected to the flange 2 of the main body of the manhole structure. The application of this utility model ensures that the manhole device at the top of the sealed high-pressure reinforced concrete waterway is leak-free, reduces the labor intensity of opening and closing the manhole cover assembly 9, ensures operational safety, and improves work efficiency.
