Description

Technical Field

[0001] The utility model relates to the technical field of valve well equipment, in particular to an assembled valve well installation structure. Background Art

[0002] In the existing water supply system, municipal drainage system and industrial production, the valve well, as one of the important facilities, is used to accommodate and control the operation of valves. However, there are some limitations in the design and installation of the traditional valve well structure, which are difficult to meet the needs of modern urban construction and industrial development.

[0003] Firstly, the traditional valve well structure usually adopts the construction methods of bricklaying or in-situ concrete casting. This method has a long construction period, low efficiency, and it is difficult to ensure the structural stability and sealing performance. In addition, the traditional valve well structure requires a large amount of manpower and material resources during the installation and disassembly processes, bringing certain difficulties to construction and maintenance.

[0004] Secondly, the traditional valve well structure lacks flexibility in the connection and fixing methods. It often needs to use additional connectors or fasteners, which not only increases the construction cost, but also reduces the structural reliability and safety. At the same time, when facing natural disasters or external impacts, the traditional valve well structure is prone to collapse or damage, bringing potential safety hazards to the water supply system and urban infrastructure. For this reason, we provide an assembled valve well installation structure. Content of the Utility Model

A T-shaped groove 5 is opened on the lower end surface of the second fixing frame 2, and a T-shaped block 7 is fixedly connected to the end of the first fixing frame 1. The T-shaped block 7 can be accurately placed on the inner wall of the T-shaped groove 5 to achieve horizontal limit and docking; a limit jack 6 is opened on the inner end wall of the T-shaped groove 5, a rectangular groove 8 is opened on the lower end surface of the T-shaped block 7, and a strip-shaped placement groove 9 is opened on the inner side wall of the rectangular groove 8. Two moving sleeve blocks 12 are slidably connected to the inner wall of the strip-shaped placement groove 9. A lapping slider 13 is fixedly connected between the two moving sleeve blocks 12. The lapping slider 13 is slidably connected to the inner wall of the rectangular groove 8. A limit insertion rod 14 is fixedly connected to one end surface of the lapping slider 13. When the end of the limit insertion rod 14 penetrates the end wall of the rectangular groove 8 and is inserted into the inner wall of the limit jack 6, vertical limit and fixation are achieved.

[0029] Among them, in order to facilitate the operation of the limit insertion rod 14, a fixing rod 10 is fixedly connected between the two end walls of the strip-shaped placement groove 9. A spring 11 is sleeved around the fixing rod 10, and a moving sleeve block 12 is slidably sleeved around the fixing rod 10. One end of the spring 11 is fixedly connected to the end wall of the strip-shaped placement groove 9, and the other end is fixedly connected to one end surface of the moving sleeve block 12. When there is no external force, the elastic force of the spring 11 keeps the limit insertion rod 14 in the inserted state.

[0030] Furthermore, an arc-shaped block 4 is fixedly connected to the periphery of the manhole cover 3. Notch grooves 15 are formed at the opposite ends of the first fixing frame 1 and the second fixing frame 2, and insertion columns 16 are fixedly connected horizontally to the inner side walls of the notch grooves 15. A through insertion hole 17 is formed through the end of the arc-shaped block 4, and the insertion column 16 is inserted into the inner wall of the through insertion hole 17 to realize the rotational connection between the manhole cover 3 and the overall frame, and at the same time prevent the manhole cover 3 from detaching.

[0031] Among them, a trigger groove 18 is formed on the surface of the manhole cover 3 to facilitate the user to pull and flip the manhole cover 3. Reinforcing blocks 19 are fixedly connected to the peripheries of both the first fixing frame 1 and the second fixing frame 2 to improve the stability of the overall structure.

[0032] The working principle of the present utility model: During installation, first align the T-shaped block 7 of the first fixing frame 1 with the T-shaped groove 5 of the second fixing frame 2 and insert them. Then press the limit insertion rod 14 to make it retract. After the T-shaped block 7 completely enters the T-shaped groove 5, release the limit insertion rod 14 so that it is inserted into the limit insertion hole 6 under the action of the elastic force of the spring 11, completing the fixation of the first fixing frame 1 and the second fixing frame 2. Subsequently, align the arc-shaped block 4 of the manhole cover 3 with the insertion column 16 and rotate and fasten them to complete the installation of the entire assembled valve well.
