[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 The flood control manhole cover warning frame shown includes a primary limiting cover 1, a secondary limiting cover 3, a tertiary limiting cover 4, and an mounting ring 5. A fixing frame 2 is welded to the inner cavity of the primary limiting cover 1. The secondary limiting cover 3 is welded to the bottom end face of the fixing frame 2. The tertiary limiting cover 4 is welded to the bottom end face of the secondary limiting cover 3. The mounting ring 5 is welded to the inner cavity of the fixing frame 2. A support rod 6 is welded to the right side of the fixing frame 2. A warning light 61 is installed on the top surface of the support rod 6.

[0025] A support guide wheel 7 is provided behind the upper end face of the mounting ring 5, and the secondary limit cover 3, the tertiary limit cover 4 and the inner cavity of the mounting ring 5 are all provided with manhole cover through holes 8. A rotating adjustment seat 9 is installed on the right side of the upper end face of the mounting ring 5. A hinge limit frame 10 is provided at the center of the manhole cover through hole 8. A limit plate 11 is provided on the left side of the hinge limit frame 10. An installation limit seat 12 is installed on the left side of the upper end face of the mounting ring 5. A limit post 13 is welded behind the installation limit seat 12. Two sets of limit posts 13 are provided. A fixing pin 14 is installed in the inner cavity of the installation limit seat 12.

[0026] The inner cavity of the primary limiting cover 1 is welded with the fixed frame 2, which provides a solid structural support for the entire warning rack. The fixed frame 2 ensures the relative position and cooperation between the components, and provides a unified force structure for the entire warning rack. The primary limiting cover 1, the secondary limiting cover 3 and the tertiary limiting cover 4 are adapted to different specifications of the wellhead aperture. By closely fitting the edge of the wellhead, the horizontal movement of the warning rack is effectively limited, preventing it from deviating from the wellhead position under the impact of water flow or other external forces. This close fit not only improves the stability of the warning rack, but also blocks larger debris from entering the wellhead to some extent. The hollow structure can guide and buffer the water flow when it flows in. When the water flow passes through the hollow part of the fixed structure, its pressure will change and be tightly adsorbed and fixed in the wellhead, so that it can also remain stable under the impact of water flow. The inner cavity of the secondary limiting cover 3 and the tertiary limiting cover 4 and the installation ring 5 are provided with well cover through holes 8, which ensure that the water flow and the hollow structure can smoothly pass through the warning rack and enter the wellhead. The support rod 6 raises the height of the warning light 61 to remind passing pedestrians that the well cover is dangerous. One end of the hinge limiting frame 10 is opened by rotating the adjusting seat 9, so that the water pipe passes through the support guide wheel 7 and enters the well interior, and the limiting plate 11 of the hinge limiting frame 10 covers the installation limiting seat 12. The limiting plate 11 is limited by the fixed bolt 14, which can prevent the limiting plate 11 from loosening or falling out under the impact of water flow or other external forces. The two groups of limiting columns 13 are tightly inserted to prevent falling out.

[0027] Example 2

[0028] Based on the embodiment 1, the scheme in embodiment 1 is further refined based on the following specific working mode, as shown in Figures 1 to 4 The details are described below:

[0029] As a preferred embodiment, the sizes of the primary limiting cover 1, the secondary limiting cover 3 and the tertiary limiting cover 4 decrease from large to small, and the primary limiting cover 1, the secondary limiting cover 3 and the tertiary limiting cover 4 together form a fixed structure. Further, the primary limiting cover 1, the secondary limiting cover 3 and the tertiary limiting cover 4 are adapted to different specifications of the wellhead from large to small, so as to be directly installed in the wellhead for clamping and fixing, greatly improving the adaptability of the warning rack and the wellhead. The fixed structure can be stably clamped in the wellhead to protect the warning rack from being washed away by water flow.

[0030] As a preferred embodiment, the four peripheral edges of the mounting ring 5 are fixed to the inner surface of the fixed frame 2 by welding, and the three groups of well lid through holes 8 correspond to the same vertical center line; further, the four peripheral edges of the mounting ring 5 are fixed to the inner surface of the fixed frame 2 by welding, and this connection mode makes the mounting ring 5 and the fixed frame 2 form a firm whole structure, and the accurate alignment of the three groups of well lid through holes 8 can ensure that the water flow enters the well mouth in the most direct way.

[0031] As a preferred embodiment, the rotating adjusting seat 9 is connected to the mounting ring 5 by a bolt, and the hinge limiting frame 10 is movably connected to the rotating adjusting seat 9 by a rotating shaft; further, the rotating adjusting seat 9 is connected to the mounting ring 5 by a bolt, which not only ensures the stability of the rotating adjusting seat 9, but also allows a certain degree of disassembly and adjustment, and the hinge limiting frame 10 is movably connected to the rotating adjusting seat 9 by a rotating shaft, so that the hinge limiting frame 10 can be flexibly rotated around the rotating shaft to facilitate opening the water inlet pipe.

[0032] As a preferred embodiment, the limiting plate 11 is inserted into one side of the mounting limiting seat 12 away from the hinge limiting frame 10, and the fixed bolt 14 is inserted into the inner cavity of the mounting limiting seat 12 and abuts against the limiting plate 11 to achieve limiting; further, the worker only needs to accurately insert the limiting plate 11 into one side of the mounting limiting seat 12, and then insert the fixed bolt 14 to complete the installation limiting, which avoids the loss of limiting of the hinge limiting frame 10, and at the same time, the water pipe can be naturally inserted into the limiting structure, and the supporting guide wheel 7 guides the movement of the water pipe to slide into the well, avoiding damage to the water pipe, and can play a certain guiding role for the water pipe.

[0033] As a preferred embodiment, the two groups of limiting columns 13 are symmetrically arranged, and the fixed bolt 14 is inserted into the space between the two groups of limiting columns 13 away from the mounting limiting seat 12 to achieve limiting; further, the two groups of symmetrically arranged limiting columns 13 provide precise positioning for the fixed bolt 14, and when the fixed bolt 14 is inserted into the mounting limiting seat 12, the end away from the mounting limiting seat 12 is inserted into the space between the two groups of limiting columns 13, which can ensure that the fixed bolt 14 is accurately positioned, avoiding its deviation or disengagement when subjected to water flow impact.

[0034] The working process of the utility model is as follows: firstly, during installation, the first limiting cover 1 is placed by aiming at the well mouth through the handle, and the size designed according to the cover type and specification of the well can be accurately positioned and clamped into the well mouth; the second limiting cover 3 and the third limiting cover 4 can be installed below the second limiting cover 3 of the well mouth in the same way, and a fixed structure that is closely matched with the well mouth and stable can be formed, so that the whole warning rack is firmly fixed at the well mouth position, effectively resisting water flow impact and other external force interference; the mounting ring 5 is fixed with the inner surface of the fixed frame 2 through the welding points on the four peripheral edges, providing a stable installation platform for other components; the supporting guide wheel 7 is welded on the rear of the upper end surface of the mounting ring 5, and when it is necessary to lay a water pipe near the well mouth, the water pipe can be guided into the well mouth along the supporting guide wheel 7, avoiding damage to the pipe body;

[0035] When further fixing of the water pipe is required, the rotating adjusting seat 9 plays a role, the rotating adjusting seat 9 connected with the mounting ring 5 through the bolt can rotate flexibly, and the hinge limiting rack 10 connected with the rotating shaft on the rotating adjusting seat 9 can also rotate, the operator rotates the hinge limiting rack 10 to the appropriate angle, so that the limiting plate 11 far away from the hinge limiting rack 10 is clamped into one side of the installation limiting seat 12, then the fixed bolt 14 is inserted into the inner cavity of the installation limiting seat 12, so that it abuts above the limiting plate 11, at this time the limiting plate 11 is firmly fixed, limiting its movement, the end of the fixed bolt 14 far away from the installation limiting seat 12 is clamped between the two groups of symmetrical limiting columns 13, further ensuring the position stability of the fixed bolt 14, so as to prevent the water pipe from moving, and during the drainage process, the second limiting cover 3, the third limiting cover 4 and the well cover through hole 8 in the inner cavity of the mounting ring 5 play a key role. Since the three groups of well cover through holes 8 correspond to the same vertical center line, the water flow can smoothly pass through these through holes and the hollow structure into the well mouth, without being hindered, ensuring the efficiency of drainage, and the fixed structure can be firmly fixed at the well mouth through the pressure drop of the water flow, the support rod 6 welded on the right side of the fixed frame 2 and the warning light 61 at the top end continuously play a role in the whole process, the warning light 61 can emit obvious warning signals in the case of dim light or at night, reminding pedestrians and vehicles to pay attention to the well mouth position, avoiding accidents and ensuring the safety of the surrounding environment, the working principle of the flood-prevention well cover warning rack with high-strength fixing structure is as above.
