Description

Technical Field

[0001] The utility model relates to the technical field of safety flat nets, in particular to a coated dense-mesh safety flat net with good flame retardancy. Background Art

[0002] Safety net is a kind of safety net used to prevent people and objects from falling. The installation plane is not perpendicular to the horizontal plane. It is mainly used for scaffolding or hanging basket above the first-floor rest platform, and horizontal protection facilities on formwork cantilever scaffolding. Safety net can be divided into different types according to material and purpose, such as nylon safety net, steel net, aluminum alloy safety net, etc. In short, safety net is an important safety protection tool that can effectively prevent people and objects from falling and ensure construction safety.

[0003] According to a disclosed coated dense mesh safety vertical net with flame retardant properties (Announcement No.: CN214885696U), in the above application, a flame retardant coating is evenly applied to the outer layer of the flammable chemical fiber mesh core to isolate the chemical fiber mesh core from the air, greatly reducing the possibility of the safety vertical net burning in a high temperature environment.

[0004] However, in actual use, the above-mentioned equipment achieves a flame retardant effect by coating the surface of the mesh with a flame retardant coating. However, when the safety net is exposed to external factors such as a cigarette butt contacting the mesh and causing a fire, the safety net will catch fire and cannot slow down or prevent the fire source, thereby reducing the flame retardant effect of the safety net. In view of this, we propose a coated dense mesh safety flat net with good flame retardant properties. Summary of the invention

[0005] The utility model aims to provide a coated dense mesh safety flat net with good flame retardancy to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a coated dense mesh safety flat net with good flame retardant performance, comprising a mounting frame, the inner surface of the mounting frame is fixedly connected to the outer surface of the net body, the surface of the net body is coated with a flame retardant coating, and the surface of the mounting frame is provided with a flame retardant structure, and the flame retardant structure includes:

[0007] A limiting hole is provided on the side wall of the mounting frame, and the limiting hole is sleeved on the outer wall of the U-shaped tube. The U-shaped tube is connected to the side wall of the tee tube through a fixed connection with a pipeline. The tee tube is convenient for connecting with multiple groups of U-shaped tubes through a pipeline. The end of the tee tube is fixedly connected with a telescopic tube, and the telescopic tube can ensure the continuous input of dry powder when the tee tube moves back and forth;

[0008] A delivery pump, one end of the telescopic tube away from the three-way tube is fixedly connected to the output end of the delivery pump, the input end of the delivery pump is connected to the dry powder box through a pipeline, the inner wall of the mounting frame is fixedly connected to the fixed end of the electric push rod, the output end of the electric push rod is fixedly connected to one side of the push plate, the other side of the push plate is hinged with the outer surface of the collar, and the collar is convenient for connecting with the push plate;

[0009] Infrared sensor, an infrared sensor is arranged inside the mounting frame, the end of the infrared sensor is fixedly connected to the inner surface of the mounting frame, and a through hole is arranged on one side of the mounting frame, which facilitates the infrared sensor to monitor the mesh body and does not hinder the installation of the mesh body.

[0010] Preferably, the end of the U-shaped tube away from the three-way tube passes through a limiting hole, the end of the delivery pump is fixedly connected to the outer surface of the mounting frame, and the side wall of the dry powder box is fixedly connected to the outer surface of the mounting frame.

[0011] Preferably, the inner surface of the collar is fixedly connected to the outer surface of the three-way pipe, and a through hole is formed on one side of the mounting bracket close to the limiting hole, and the through hole is sleeved on the outer wall of the infrared sensor.

[0014] Preferably, the rubber ring is arranged on the outer wall of the infrared sensor.

[0015] Compared with the prior art, the utility model provides a coated dense mesh safety flat net with good flame retardant performance, which has the following beneficial effects:

[0016] 1. The coated dense mesh safety flat net with good flame retardant performance is provided with through holes to facilitate infrared sensors to monitor the fire source on the surface of the net. When the net is caught fire by external factors, the dry powder drawn into the dry powder box by the delivery pump is transferred to the inside of multiple groups of U-shaped tubes through the three-way pipe for spraying. The electric push rod pushes and pulls the push plate back and forth so that the sleeve drives the three-way pipe to move parallel to a certain extent, so that the U-shaped tube can swing back and forth when spraying dry powder to expand the contact area between the dry powder and the upper and lower sides of the net, thereby slowing down or preventing the combustion process of the net and improving the flame retardant effect of the safety net.

[0017] 2. The coated dense mesh safety flat net with good flame retardant performance is convenient for the fixing frame to be installed inside the mounting frame by means of bolts and ear plates. The setting of the rubber ring prevents the infrared sensor from colliding with the through hole during installation or disassembly, which is convenient for maintenance of the infrared sensor and thus improves the stability of infrared sensor monitoring.

[0027] In the present invention, when in use, the infrared sensor 12 is inserted into the through hole 13.
