Technical Field

[0001] The utility model relates to the field of manhole cover protection nets, in particular to a protection net for water supply and drainage manhole covers in municipal engineering. Background Technique

[0002] Municipal engineering includes various municipal public works such as urban roads and bridges, water supply and drainage, electricity, communication, lighting, etc. The protection net for water supply and drainage manhole covers is a device used to protect the safety of water supply and drainage manhole covers in municipal engineering, which can effectively prevent the accidental fall of manhole covers or the accidental fall of personnel into the well, ensure the safety of pedestrians and vehicles, and is of great significance for improving urban safety and ensuring the safety of people's lives and property. The existing protection nets for water supply and drainage manhole covers are installed and connected unidirectionally during use. Due to the influence of water flow and vibration, local deviation damage occurs, resulting in the loss of overall protection performance and the reduction of overall maintenance effect. Therefore, we propose a protection net for water supply and drainage manhole covers in municipal engineering to solve the problems mentioned above. Content of the Utility Model

[0005] Preferably, the first pressure-bearing component bears pressure upwards and can also reinforce the support of the manhole cover. The second pressure-bearing component bears pressure downwards to form a stable support, avoiding the influence of upper vibration and water flow impact, and performing an interactive support operation. Through the installation positioning component, it is distributed at the outer end of the main body support component, and sectional installation operation can be carried out to improve the protection of installation stability.

Through the clearance rings, the strength of the outer positioning ring, the first support ring, the second support ring and the third support ring is improved, thereby weakening the resonance performance.

[0007] Preferably, multiple groups of spring cords are sequentially connected in the circumferential direction on the outer positioning ring, the first support ring, the second support ring and the third support ring. A spring damper is provided inside the spring cord.

[0011] Preferably, limiting tooth blocks are arranged along the inner sides of the first clamping claw and the second clamping claw. Perforations are provided through the first clamping claw and the second clamping claw. Longitudinal and transverse installation connections can be formed by using the clamping groove and the perforations, and the limiting tooth blocks increase the clamping anti-slip strength.

[0012] The beneficial effects of the present utility model:

[0013] 1. Different from the previous one-way installation and connection of the sampling, due to the influence of water flow and vibration, partial deviation damage occurs, resulting in the loss of the overall protection performance and the reduction of the overall maintenance effect. The first pressure-bearing component and the second pressure-bearing component are set with the same structure and are distributed up and down, which can well protect the main support component. The first pressure-bearing component bears pressure upward and can also strengthen the support of the manhole cover.

[0014] 2. When in use, it is first installed through the installation and positioning component, and then the outer installation sleeve of the frustum is installed and connected respectively, so that the first pressure-bearing component and the second pressure-bearing component are pulled open one up and one down. When the water flow drops, the water flow agitates the outer end of the frustum and the wire mesh on the inner ring for preliminary diversion, and then passes through the first support ring, the second support ring and the third support ring, and multiple spring ropes and shock-absorbing ball sleeves to slow down the water flow impact and protect the structure for diversion, improving the overall protection performance.
