Description

Technical Field

[0001] This utility model relates to the field of hoses, and in particular to a large-diameter, high-pressure explosion-proof hose. Background Technology

[0002] Large-diameter hoses typically refer to hoses with larger diameters, which are widely used for conveying liquids, gases, powders, and other substances. They have strong flexibility and pressure resistance.

[0003] When using large-diameter hoses for high-pressure cleaning in construction projects, the continuous impact of high-pressure water flow and frequent bending often cause fatigue damage to the hose walls. This not only leads to a significant decrease in cleaning efficiency, but the disorderly spraying of high-pressure water may also cause physical injury to operators and even damage surrounding facilities, posing certain safety hazards during use. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using large-diameter hoses for high-pressure cleaning in construction projects, the existing hoses often suffer from fatigue damage due to the continuous impact and frequent bending of the high-pressure water flow. This not only leads to a significant decrease in cleaning efficiency, but the disorderly spraying of high-pressure water may also cause physical injury to operators and even damage surrounding facilities, posing certain safety hazards during use.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a large-diameter high-pressure explosion-proof hose, including an external hose, an internal hose, and several connecting blocks. The two ends of the several connecting blocks are respectively fixedly installed on the outer surface of the internal hose and the inner wall of the external hose. An explosion-proof device is provided between the inner wall of the external hose and the outer surface of the internal hose. The explosion-proof device can reinforce the outer surface of the internal hose by reinforcing wire mesh and several reinforcing ribs to improve the pressure resistance. At the same time, a pressure relief mechanism is provided in the inner wall of the external hose so that when the internal hose ruptures and the pressure reaches a certain value, the pressure between the two can be relieved to achieve the explosion-proof effect.

[0006] Preferably, the explosion-proof device includes a reinforcing wire mesh, wherein the inner wall of the reinforcing wire mesh is sleeved and installed on the outer surface of the built-in flexible hose, and both sides are fixedly installed on one side of a plurality of connecting blocks; a plurality of reinforcing ribs, wherein one side of the reinforcing ribs is fixedly installed on the outer surface of the reinforcing wire mesh; and a pressure relief mechanism, wherein the pressure relief mechanism is disposed in the inner wall of the external flexible hose, and is used to relieve the pressure inside the external flexible hose to achieve the explosion-proof effect.

[0007] The aforementioned components achieve the following effects: By incorporating explosion-proof devices, when using large-diameter hoses for high-pressure cleaning in construction projects, the reinforcing wire mesh and several reinforcing ribs enhance the strength of the internal hose and improve its pressure resistance, thereby reducing the possibility of bursting. If the internal hose ruptures, water will enter between the external hose and the internal hose, increasing the flow area and performing the first step of pressure relief and explosion prevention. If the pressure continues to increase, the pressure relief mechanism on the external hose will perform a secondary pressure relief process. This effectively reduces the problem of pipe wall fatigue damage, improves cleaning efficiency, avoids disorderly spraying of high-pressure water that could cause physical injury to operators or damage to surrounding facilities, and reduces safety hazards during use.

[0008] Preferably, the inner wall of the external flexible tube is fixedly equipped with a plurality of spikes, which are arranged at equal intervals.

[0009] The effect achieved by the above-mentioned components is as follows: by setting spikes, when the internal hose expands due to high-pressure water flow, when a part of the expansion protrudes into the inner wall of the reinforcing wire mesh to a certain height, it will touch the spikes, and the spikes will puncture the internal hose, thereby achieving the effect of explosion prevention.

[0010] Preferably, a plurality of reinforcing blocks are fixedly installed on both sides of the reinforcing rib, wherein one side of the reinforcing block is fixedly installed on the outer surface of the reinforcing wire mesh.

[0011] The effect achieved by the above components is that by setting up reinforcing blocks, the connection area between the reinforcing ribs and the reinforcing wire mesh can be increased, thereby improving the reinforcement effect.

[0012] Preferably, the pressure relief mechanism includes several brackets, and the inner wall of the external hose has several circular holes, wherein both ends of the brackets are fixedly installed in the inner wall of the circular holes; and several springs, wherein one end of the spring is fixedly installed on one side of the bracket, and a piston plate is fixedly installed on one end of the spring.

[0013] The effect achieved by the above-mentioned components is as follows: by setting up a pressure relief mechanism, when the water pressure is still relatively high after the internal hose ruptures and water pressure enters between the internal hose and the external hose, the piston plate will be automatically pushed open, causing the spring to be stretched between the internal hose and the piston plate. In this way, the pressure between the external hose and the internal hose will overflow from the round hole, achieving the effect of pressure relief. Therefore, it is possible to prevent the external hose from bursting and reduce the safety hazards during use.

[0014] Preferably, the outer surface of the external flexible tube is provided with a plurality of grooves, the inner wall of the grooves is connected to the inner wall of the circular hole, and one side of the piston plate abuts against one side of the inner wall of the groove.

[0015] The effect achieved by the above components is that by setting the groove, the piston plate can be housed in the inner wall of the groove, so that it does not protrude from the outer surface of the external hose, making it convenient for the use of the external hose.

[0016] Preferably, a sealing strip is fixedly installed on the outer surface of the piston plate, wherein the outer surface of the sealing strip abuts against one side of the inner wall of the groove.

[0017] The effect achieved by the above components is that by setting a sealing strip, the contact friction of the outer surface of the piston plate can be increased, and the gap between the piston plate and the groove can be sealed and plugged, thereby improving the sealing performance of the piston plate.

[0018] Preferably, a telescopic rod is fixedly installed on one side of the bracket, and one end of the telescopic rod passes through the inside of the spring and is fixedly installed on one side of the piston plate.

[0019] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0020] The beneficial effects of this utility model are:

[0021] By installing explosion-proof devices, when using large-diameter hoses for high-pressure cleaning in construction projects, reinforcing wire mesh and several reinforcing ribs can enhance the strength of the internal hose and improve its pressure resistance, thereby reducing the possibility of bursting. If the internal hose ruptures, the water will enter between the external hose and the internal hose, increasing the flow area and performing the first step of pressure relief and explosion prevention. If the pressure continues to increase, the pressure relief mechanism on the external hose will perform a second pressure relief process. This effectively reduces the problem of pipe wall fatigue damage, improves cleaning efficiency, avoids disorderly spraying of high-pressure water that may cause physical injury to operators or damage to surrounding facilities, and reduces safety hazards during use.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1-4 The large-diameter, high-pressure explosion-proof hose shown includes an external hose 1, an internal hose 3, and several connecting blocks 4. The two ends of the connecting blocks 4 are respectively fixedly installed on the outer surface of the internal hose 3 and the inner wall of the external hose 1. An explosion-proof device 2 is provided between the inner wall of the external hose 1 and the outer surface of the internal hose 3. The explosion-proof device 2 can reinforce the outer surface of the internal hose 3 by means of reinforcing wire mesh 21 and several reinforcing ribs 22 to improve the pressure resistance. At the same time, a pressure relief mechanism 25 is provided in the inner wall of the external hose 1 so that when the internal hose 3 ruptures and the pressure reaches a certain value, it can relieve the pressure between the two to achieve the explosion-proof effect.

[0031] Figure 1-4The explosion-proof device 2 shown includes a reinforcing wire mesh 21, wherein the inner wall of the reinforcing wire mesh 21 is sleeved and installed on the outer surface of the built-in flexible hose 3, and both sides are fixedly installed on one side of a plurality of connecting blocks 4; a plurality of reinforcing ribs 22, wherein one side of the reinforcing ribs 22 is fixedly installed on the outer surface of the reinforcing wire mesh 21; and a pressure relief mechanism 25, wherein the pressure relief mechanism 25 is disposed in the inner wall of the external flexible hose 1, and is used to relieve the pressure inside the external flexible hose 1 to achieve the explosion-proof effect. By installing the explosion-proof device 2, when using large-diameter hoses for high-pressure cleaning in construction projects, the reinforcing wire mesh 21 and several reinforcing ribs 22 can enhance the strength of the inner hose 3 and improve its pressure resistance, thereby reducing the possibility of bursting. When the inner hose 3 ruptures, the water will enter between the outer hose 1 and the inner hose 3, increasing the flow area and performing the first step of pressure relief and explosion prevention. If the pressure continues to increase, the pressure relief mechanism 25 on the outer hose 1 will perform secondary pressure relief, thereby effectively reducing the problem of pipe wall fatigue damage, improving cleaning efficiency, avoiding disorderly spraying of high-pressure water that could cause physical injury to operators or damage to surrounding facilities, and reducing safety hazards during use.

[0032] Figure 1-4 The inner wall of the external flexible hose 1 shown is fixedly equipped with several spikes 24, which are arranged at equal intervals. By setting the spikes 24, when the internal flexible hose 3 expands due to high-pressure water flow, when a portion of the expanded hose protrudes into the inner wall of the reinforcing wire mesh 21 to a certain height, it will touch the spikes 24, causing the internal flexible hose 3 to puncture, thus achieving an explosion-proof effect. Several reinforcing blocks 23 are fixedly installed on both sides of the reinforcing rib 22, with one side of each reinforcing block 23 fixedly installed on the outer surface of the reinforcing wire mesh 21. By setting the reinforcing blocks 23, the connection area between the reinforcing rib 22 and the reinforcing wire mesh 21 can be increased, improving the reinforcement effect.

[0033] Figure 1-4 The pressure relief mechanism 25 shown includes several supports 252, and several circular holes 251 are opened on the inner wall of the external hose 1. Both ends of the supports 252 are fixedly installed in the inner wall of the circular holes 251. Several springs 253 are also included, with one end of each spring fixedly installed on one side of the support 252 and a piston plate 254 fixedly installed on the other end. By setting up the pressure relief mechanism 25, when the internal hose 3 ruptures and the water pressure entering between the internal hose 3 and the external hose 1 is still relatively high, the piston plate 254 will be automatically pushed open, causing the springs 253 to be stretched between the internal hose 3 and the piston plate 254. In this way, the pressure between the external hose 1 and the internal hose 3 will overflow from the circular holes 251, achieving the effect of pressure relief. This prevents the external hose 1 from bursting and reduces the safety hazards during use.

[0034] Figure 1-4The outer surface of the external flexible hose 1 shown has several grooves 255. The inner wall of each groove 255 is connected to the inner wall of a circular hole 251, and one side of the piston plate 254 abuts against one side of the inner wall of the groove 255. By providing the grooves 255, the piston plate 254 can be housed within the inner wall of the groove 255, thus preventing it from protruding from the outer surface of the external flexible hose 1 and facilitating its use. A sealing strip 256 is fixedly installed on the outer surface of the piston plate 254, with its outer surface abutting against one side of the inner wall of the groove 255. By providing the sealing strip 256, the contact friction of the outer surface of the piston plate 254 can be increased, and the gap between the piston plate 254 and the groove 255 can be sealed, improving the sealing performance of the piston plate 254. A telescopic rod 257 is fixedly installed on one side of the bracket 252, with one end of the telescopic rod 257 passing through the interior of the spring 253 and then fixedly installed on one side of the piston plate 254. By setting the telescopic rod 257, the inner wall of the spring 253 can be supported and reinforced, making it less prone to damage during use.

[0035] Working principle: When using large-diameter hoses for high-pressure cleaning in construction projects, the reinforcing wire mesh 21 and several reinforcing ribs 22 enhance the strength of the inner hose 3 and improve its pressure resistance, thereby reducing the possibility of bursting. When the inner hose 3 expands due to the high-pressure water flow, when some parts of the expansion protrude into the inner wall of the reinforcing wire mesh 21 to a certain height, they will touch the spikes 24, which will puncture the inner hose 3, achieving a preliminary explosion-proof effect. When the inner hose 3 ruptures, the water will enter between the outer hose 1 and the inner hose 3, increasing the risk of bursting. In terms of flow area, the first step of pressure relief and explosion prevention is performed. When the pressure is still relatively high after the water pressure enters between the inner hose 3 and the outer hose 1, the piston plate 254 will be automatically opened, causing the spring 253 to be stretched between the piston plate 254 and the outer hose 1. In this way, the pressure between the outer hose 1 and the inner hose 3 will overflow from the round hole 251, achieving the effect of pressure relief. Therefore, it effectively reduces the problem of pipe wall fatigue and damage, improves cleaning efficiency, avoids disorderly spraying of high-pressure water from causing physical injury to operators or damaging surrounding facilities, and reduces safety hazards during use.
