The connection hole between the pre-tightening fixing plate 12 and the fastening bent plate 2 on the clamp body 1 adopts a waist hole, and the connection hole between the clamp body 1 and the fastening bent plate 2 adopts a waist hole, so that it can be connected normally when the installation position is inaccurate. One end of the flange 7 is welded and fixed to the welded three-to-one-line clamp drainage plate 8, and the other end is welded and fixed to the pipe mother 6 of the welded three-to-one-line clamp.

[0018] Telescopic drain plates 3 are symmetrically arranged on both sides of the clamp body 1, and fastening bent plates 2 are symmetrically arranged on both sides of the clamp body 1, wherein the welded three-into-one-line clamp drain plate 8 on each side is located between the telescopic drain plate 3 and the fastening bent plate 2, that is, the fastening bent plate and the telescopic drain plate are respectively installed on both sides of the welded three-into-one-line clamp drain plate.

[0019] The telescopic drainage plate 3 adopts a telescopic soft connection structure, which is a pure aluminum flat plate at both ends and a bent portion in the middle. The bent portion is formed by welding the end portions after stacking multiple pieces of aluminum foil and fixed to the pure aluminum flat plates at both ends. The telescopic portion of the telescopic drainage plate is at the bent position, and the bent position is formed by welding the end portions after stacking multiple pieces of aluminum foil, and can be bent and deformed to achieve the purpose of telescoping.

[0022] In summary, the advantages of the utility model are:

[0023] 1. The reinforced drainage clamp has a compact structure. Based on the original design, it adopts a bolt fastening structure, waist hole design, and telescopic structure design, which makes it easy to install and the position can be fine-tuned, thereby improving the adaptability of the product.

[0024] 2. The reinforced drainage clamp adopts high-strength fastening bent plate to connect the pipe mother and the end plate, which reduces the tensile force on the weld, improves the strength of the welded three-to-one line clamp, and reduces the possibility of desoldering and tearing of the line clamp.

[0025] 3. The reinforced drainage clamp adopts a telescopic drainage plate to increase the fitting surface between the telescopic drainage plate and the connecting piece in a telescopic manner, effectively improving the drainage effect of the original equipment.

[0026] The high-strength fastening bent plate is made of high-strength aluminum alloy plate or steel plate, which is bent to play a mechanical connection role; the corresponding telescopic guide plate is made of pure aluminum and consists of aluminum plate and aluminum foil, which plays a diversion role; the clamp body and the clamp cover are both cast aluminum parts, which can meet the mechanical connection and diversion functions at the same time.

[0027] In addition, the middle curved part of the telescopic drainage plate is a flexible connection formed by superimposing aluminum foil, and the two end plates are pure aluminum flat plates. The flexible connection structure makes the relative position of the two plates adjustable. The flexible connection structure can improve the long-term anti-vibration and anti-fatigue performance of the drainage plate and improve the stability of the device.

[0028] This case adopts a flexible connection structure. Under actual wind vibration conditions, the fastened bent plate bears part of the wire tension, reducing the tension on the weld between the pipe mother and the flange, and the telescopic guide plate increases the flow capacity, which is an enhanced protection solution.
