Description
Technical Field
[0001] The utility model relates to the technical field of fire detection equipment, and more particularly to a fire hose bending and water leakage detection device. Background Art
[0002] Fire hoses are essential firefighting equipment, playing a crucial role in firefighting. They are used to transport water to the scene, quickly providing large quantities of water and effectively controlling and extinguishing fires. However, prolonged idleness or harsh environmental conditions can lead to problems such as aging, embrittlement, and cracking, which can affect their proper function. Regular inspections of fire hoses can identify potential problems promptly, ensuring their reliable operation at critical moments and protecting lives and property. Common fire hose inspections include leak detection, strength testing, and corrosion resistance testing.
[0003] In the existing water leakage detection process, the section of the fire hose to be tested is filled with water, so that the fire hose is in a straight state and observed to see if there is any leakage. There are two problems with this detection. First, in actual use, the fire hose will inevitably need to go around buildings or obstacles, so there will definitely be bending conditions. Only in the bent state will the cracks on the surface of the fire hose be exposed. The water leakage detection in the straight state is not comprehensive and cannot guarantee the safety of the fire hose. Second, the length of the existing fire hose is generally long, at 20 to 25 meters. The detection equipment needs to be frequently disassembled or pulled back to pull the fire hose, which has low detection efficiency. Frequent disassembly and assembly will also cause unnecessary damage to the fire hose. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:
[0006] A fire hose bending leakage detection device comprises a fire hose, one end of the fire hose is connected to a water filling pipe, one end of the fire hose is supported and fixed by a support below, the other end of the fire hose is inserted into a plug, the outer side of the plug is connected to the inner side of the support through an elastic telescopic column, a mobile water leakage detection groove is provided on the middle section of the fire hose, driving wheels are provided on the sides of the mobile water leakage detection groove, parking plates are provided at the lower ends of the front and rear sides of the mobile water leakage detection groove, a guide ring is provided on the outer side of the plug, and a bracket leg is provided below the guide ring.
[0007] As a further optimization of this solution, the upper ends of the two side edges of the mobile water leakage detection trough are provided with horizontal H-shaped sliding bars, and a number of inverted concave sliding seats are installed between the horizontal H-shaped sliding bars. The middle area of the inverted concave sliding seat is hollowed out with a rectangular through groove, and a vertical bending component is slidably installed inside the rectangular through groove.

[0011] Compared with the existing technology, the beneficial effects of the utility model are as follows:
[0012] The utility model provides an elastic telescopic column, a support and a guide ring structure, which can facilitate the bending of the fire hose. When the fire hose passes through the horizontal bending component and the vertical bending, the other end and the plug slide inward along the inner side of the guide ring. After completing the detection of a certain area, the fire hose is reset under the elastic force of the elastic telescopic column, and the other end and the plug slide to the initial position.
[0013] The utility model provides a mobile water leakage detection slot structure with a through hole and cooperates with the traveling wheels on all sides, which can be moved along the detection position of the fire hose, so as to facilitate continuous water leakage detection of each section of the entire fire hose, without the need for frequent disassembly and assembly, and the flexible sleeve structure can reduce damage to the fire hose;
[0014] In the present invention, by providing a transverse bending component and a vertical bending structure, the fire hose detection section can be bent and adjusted into various shapes according to detection needs, which is more in line with the actual use conditions of the fire hose and provides more comprehensive detection safety.

Figure 1 and Figure 2 As shown, the present application includes a fire hose 2, an end 3 of the fire hose 2 is connected to a water filling pipe 4, the end 3 of the fire hose 2 is supported and fixed by the support 1 below, the other end 3 of the fire hose 2 is inserted into a plug 8, the outer side of the plug 8 is connected to the inner side of the support 1 through an elastic telescopic column 5, a mobile water leakage detection groove 6 is provided on the middle section of the fire hose 2, and the sides of the mobile water leakage detection groove are provided with driving wheels 7, and the lower ends of the front and rear sides of the mobile water leakage detection groove 6 are provided with parking plates 13, a guide ring 9 is provided on the outer side of the plug 8, and a bracket leg is provided below the guide ring 9;
[0023] like Figure 3 As shown, the upper ends of both sides of the mobile water leakage detection trough 6 are provided with horizontal H-shaped slide bars 10, and a number of inverted concave sliding seats 11 are set between the horizontal H-shaped slide bars 10. The middle area of the inverted concave sliding seat 11 is hollowed out with a rectangular through groove, and a vertical bending component is slidably installed inside the rectangular through groove. Several horizontal bending components are hung on the edges of both sides of the mobile water leakage detection trough 6. Through holes 14 are processed on the front and rear sides of the mobile water leakage detection trough 6, and the fire hose 2 is passed through the through hole 14. Flexible sleeves 12 are provided on the outside of the through hole 14;
[0024] like Figure 4 As shown, the lateral bending assembly includes an inverted concave card plate 15, which is fixed to the outer side of the mobile water leakage detection tank 6 by bolts 16 on the outer side. A telescopic connecting rod 17 is provided inwardly at the lower end of the inner side of the inverted concave card plate 15. The outer end of the telescopic section of the telescopic connecting rod 17 is connected to the non-rotating part of the rotating bearing seat 18, and the rotating part of the rotating bearing seat 18 is connected to the outer arc-shaped top ring 19.
[0025] like Figure 5 As shown, the vertical bending assembly includes upper and lower parallel clamps 21, which slide on the rectangular through groove of the inverted concave sliding seat 11, and the telescopic link 17 passes vertically between the clamps 21. The lower end of the telescopic section of the telescopic link 17 is connected to the non-rotating part of the rotating bearing seat 18, and the rotating part of the rotating bearing seat 18 is connected to the external retaining ring 20. The retaining ring 20 consists of an upper fixed part and a lower rotating part, wherein the fixed part and the rotating part are tightened and limited by a bolt 16 on one side.
[0026] Specifically, before the inspection, the end 3 of the fire hose 2 is fixed on the support 1 and connected to the water filling pipe 4.
