Leakage-proof inspection device for tear-resistant fire hose

Abstract

The utility model relates to the technical field of fire hoses, discloses a leakage-proof inspection device for a tear-resistant fire hose, and solves the problem that the detection of the leakage-proof inspection device for the fire hose is not meticulous enough. Through the air pump, the box body and the moving block, the fire hose is placed in the box body, then water is injected into the box body, the connecting end of the fire hose is connected with the air pump, external air extracted by the air pump is injected into the fire hose, the other end of the fire hose is blocked, and therefore whether bubbles emerge or not can be observed, and the fire hose can be conveniently taken out. In addition, in order to avoid the situation that bubbles are not obvious due to the fact that a damaged opening is too small, a motor drives a lead screw to rotate, a movable block moves along the outer surface of the lead screw, the movable block moves to the position above a certain section of fire hose, then the movable block descends through extension of an electric push rod, and therefore the situation that bubbles are not obvious is avoided. Therefore, the outer surface of the fire hose is extruded, and obvious bubbles can appear if the fire hose is damaged.

[0002] Since the fire hose needs to withstand great water pressure during firefighting to ensure that the water column can be sprayed to a specified height, the sealing of the fire hose needs to be ensured. However, most of the existing fire hose leakage inspection devices are full-belt inspections, which makes it difficult to detect some small damaged openings. After a period of time, these tiny damaged openings will be enlarged by the high-pressure water pressure, thus creating a danger. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0019] Combination Figure 1 A leak-proof inspection device for tear-resistant fire hoses comprises a bottom plate 1 and a box body 2 arranged on the upper surface of the bottom plate 1, a detection component 3 for detection is arranged inside the box body 2, and a fire hose 4 is placed inside the box body 2.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] Embodiment 1:

[0022] See also Figure 1-Figure 3 The detection component 3 includes a motor 31 fixedly mounted on one side of the box body 2, a screw rod 32 fixedly mounted on the output end of the motor 31, and a slider 33 threadedly connected to the outer surface of the screw rod 32. An electric push rod 34 is arranged at the bottom of the slider 33. A moving block 35 is fixedly mounted on the telescopic end of the electric push rod 34. The bottom of the moving block 35 contacts the outer surface of the fire hose 4. An air pump 36 is arranged on the upper surface of the bottom plate 1. One end of the air pump 36 is connected to one end of the fire hose 4, and the other end of the air pump 36 is connected to the outside. A water connection joint and a drainage head are arranged on one side of the box body 2. The fire hose 4 is placed inside the box body 2, and the connecting end of the fire hose 4 is located outside the box body 2. Then, the water connection joint is used to connect the fire hose 4 to the outside of the box body 2. Water is injected into the box body 2, and then the connecting end of the fire hose 4 is connected to the air pump 36. The outside air extracted by the air pump 36 is injected into the fire hose 4, and the other end of the fire hose 4 is blocked. Therefore, it is possible to observe whether there is a leakage by observing whether there are bubbles. In addition, in order to avoid the damage being too small to cause the bubbles to be unclear, the motor 31 can be used to drive the screw rod 32 to rotate, so that the moving block 35 moves along the outer surface of the screw rod 32, so that the moving block 35 moves to the top of a certain section of the fire hose 4, and then the moving block 35 is lowered by the extension of the electric push rod 34, thereby squeezing the outer surface of the fire hose 4. If there is damage, more obvious bubbles will appear.

[0023] A bracket 5 is fixedly installed on the inner wall of the box body 2, and a spring 51 is provided on the upper surface of the bracket 5. A clamping block 52 is provided at one end of the spring 51. The bracket 5 is symmetrically arranged in two groups. A hydraulic rod 53 is provided on the inner wall of the box body 2. The upper surface of the other group of brackets 5 is fixedly connected to the telescopic end of the hydraulic rod 53 to fix the two ends of the fire hose 4 to prevent the detection from causing the position to occur.

[0024] The inner wall of the box body 2 is provided with fixed columns 6, and the fixed columns 6 are arranged in multiple groups. The fire hose 4 is serpentinely wrapped around the outer surface of the multiple groups of fixed columns 6. The appropriate number of fixed columns 6 can be selected according to the different lengths of the fire hose 4 for winding, so as to further prevent the fire hose 4 from displacement.

[0025] Circular grooves are provided on both sides of the box body 2 , and sealing gaskets 7 are provided on both sides of the circular grooves. The outer surface of the fire hose 4 contacts the inside of the sealing gasket 7 to prevent the water in the box body 2 from overflowing.

[0026] The moving block 35 is a component made of a transparent material to prevent bubbles from being generated and covered by the moving block 35 during squeezing.

[0027] A transparent plate 8 is hinged on one side of the box body 2. The box body 2 is sealed by closing the transparent plate 8, so that the fire hose 4 can be placed conveniently, and the transparent plate 8 can be used to observe the internal situation of the box body 2 in time.

[0028] Specifically, the fire hose 4 is placed inside the box body 2, and the two ends of the fire hose 4 are located on the upper surface of the bracket 5. The middle part can be wound around a suitable number of fixing columns 6 according to the different lengths of the fire hose 4 to prevent the fire hose 4 from being displaced. Then the hydraulic rod 53 is controlled to extend to make the other group of brackets 5 descend, so that the two ends of the fire hose 4 are clamped and fixed by the two groups of clamping blocks 52, and then water is injected into the box body 2 through the water connecting joint. Since the connecting end of the fire hose 4 is located outside the box body 2, the part where the fire hose 4 passes through the box body 2 is blocked by the sealing gasket 7 to prevent the water in the box body 2 from overflowing. Then the connecting end of the fire hose 4 is connected to the air pump 36, and the outside air extracted by the air pump 36 is injected into the fire hose 4, and the other end of the fire hose 4 is blocked, so that it can be passed. By observing whether bubbles emerge, it can be determined whether there is a leakage. In addition, in order to avoid the damage being too small to make the bubbles inconspicuous, the motor 31 can be used to drive the screw rod 32 to rotate, so that the moving block 35 moves along the outer surface of the screw rod 32, so that the moving block 35 moves to the top of a certain section of the fire hose 4, and then the moving block 35 is lowered by the extension of the electric push rod 34, thereby squeezing the outer surface of the fire hose 4. If there is damage, more obvious bubbles will appear, and the moving block 35 is a component made of transparent material to prevent bubbles from being generated during squeezing and covering the moving block 35. In addition, a transparent plate 8 is hinged on one side of the box 2. By closing the transparent plate 8, the box 2 is sealed, so that the fire hose 4 is placed conveniently, and the transparent plate 8 can observe the internal situation of the box 2 in time.
