Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water intake device. Background Art

[0002] In some old urban areas and urban villages, even if outdoor fire hydrants are installed on both sides of the road, fire trucks may not be able to directly reach or approach the fire scene in time due to narrow roads, height restrictions, occupying the road for business, illegal parking and other reasons. They cannot directly use the outdoor fire hydrants near the fire scene to put out water to extinguish the fire. Therefore, using a hand-lift motor pump to draw water nearby for fire extinguishing is an effective solution. Therefore, a water inlet is required to allow water to enter its interior and then enter the water pipe.

[0003] For example, patent announcement number CN202321963664.9 discloses a fire-fighting water inlet, which drives the gear to rotate through a motor, and rotates the first and second scrapers through the meshing relationship between the gear and the gear ring, thereby achieving the purpose of cleaning the outside of the shell and the cover plate. However, in actual use, the water inlet is often set under the water surface, which is prone to the risk of leakage and low safety. In addition, the cost of using the motor is high and it is easy to be damaged. There are certain defects and shortcomings, and therefore, it needs to be improved. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a fire water intake device, which has the following beneficial effects:

[0016] 1. The utility model provides a conical tube on one side of the water inlet body, a circular tube on the other side of the conical tube, and a water distributor rotatably connected to the annular rotating seat in the circular tube. The water distributor is composed of an annular cylinder, a water distributor and an arc-shaped drainage pipe. Water enters the annular cylinder and is discharged through the arc-shaped drainage pipe. When discharged, a counter-thrust force is generated to rotate the annular cylinder and the water distributor, driving the rotating rod to rotate rapidly, and then rotating the first scraper, the rotating ring and the second scraper to clean the foreign matter outside the water inlet body. This solution does not require the aid of motor equipment, and uses hydraulic action to realize the rapid rotation of the first and second scrapers.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a fire-fighting water inlet proposed in one embodiment of the utility model includes a circular tube 1, a conical tube 2 and a water inlet body 3, the conical tube 2 is connected between the circular tube 1 and the water inlet body 3, a cover plate 4 is fixedly connected to one side of the water inlet body 3, the water inlet body 3 and the cover plate 4 are both provided with water inlet holes 10 distributed in an array, and an annular rotating seat 16 is integrally formed in the circular tube 1, and a water distributor 15 is rotatably connected to the annular rotating seat 16, and the water distributor 15 includes an annular cylinder 1501 rotatably connected to the annular rotating seat 16, and a water distributor 15 is connected to the annular cylinder 1501. A water distribution pipe 1502, one side of which is connected to an array-distributed arc-shaped drainage pipe 1503, a rotating rod 12 is fixedly connected at the center of the water distribution pipe 1502 along the axial direction of the circular tube 1, the conical tube 2, and the water inlet body 3, the end of the rotating rod 12 extends to the outside of the cover plate 4 and is fixed with a fixed seat 6, a first scraper 7 is fixedly connected to the fixed seat 6, and a swivel 5 is rotatably connected to the cover plate 4, the swivel 5 is connected and fixed to the end of the first scraper 7, and a second scraper 8 is fixedly connected to the swivel 5, and the second scraper 8 is located outside the water inlet body 3.

[0026] It should be noted that the circular tube 1, the conical tube 2 and the water inlet body 3 are the main parts of the fire water inlet. The conical tube 2 is connected between the circular tube 1 and the water inlet body 3 to realize water intake for fire-fighting equipment. The cover plate 4 is fixedly connected to one side of the water inlet body 3, and a water inlet hole 10 is opened on the water inlet body 3 and the cover plate 4. Water enters the water inlet body 3 through the water inlet hole 10, and then is discharged through the conical tube 2 and the circular tube 1. The circular tube 1 is connected to an external water pipe for fire-fighting water supply. An annular rotating seat 16 is arranged at the water inlet in the circular tube 1. The setting of the annular rotating seat 16 is used for the installation of the water distributor 15. The water distributor 15 consists of an annular cylinder 1501, a water distributor pipe 1502 and an arc shaped drain pipe 1503. When water enters the conical tube 2, it will enter the annular cylinder 1501 and then be discharged through the arc-shaped drain pipe 1503. The arc-shaped drain pipe 1503 is designed to be arc-shaped, which can generate a reverse thrust when spraying, thereby causing the annular cylinder 1501 and the water distribution pipe 1502 to rotate, and the sprayed water flow will counteract the circular tube 1 to provide water for fire fighting. When the annular cylinder 1501 and the water distribution pipe 1502 rotate, the rotating rod 12 can be driven to rotate, thereby causing the swivel 5, the first scraper 7 and the second scraper 8 to rotate. When the first scraper 7 rotates, the dirt on the outside of the cover plate 4 can be cleaned, and when the second scraper 8 rotates, the dirt on the outside of the water inlet body 3 can be cleaned to avoid clogging by foreign matter.

[0027] like Figure 2 As shown, in some embodiments, a limit plate 13 is fixedly connected to the connection between the conical tube 2 and the water inlet body 3, the rotating rod 12 is rotatably connected to the limit plate 13 and the cover plate 4, and a drainage cavity is provided on the limit plate 13.

[0028] It should be noted that by setting the limit plate 13, the setting of the limit plate 13 can achieve the rotation limit effect of the rotating rod 12, so that the rotating rod 12 can rotate stably, and by opening a drainage cavity groove on the limit plate 13, normal water inlet of the device can be achieved.

[0029] like Figure 2 As shown, in some embodiments, a first filter screen 11 is fixedly connected to the inner wall of the water inlet body 3 , and a second filter screen 14 is fixedly connected to one side of the cover plate 4 .

[0030] It should be noted that the arrangement of the first filter screen 11 and the second filter screen 14 can protect against dirt and avoid the entry of foreign matter.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the conical tube 2 is fixedly connected with hanging plates 9 distributed in an array, and the hanging plates 9 are covered on the outside of the water inlet body 3.

[0032] It should be noted that the hanging plate 9 is L-shaped, which can protect the outer side of the water inlet body 3 and avoid clogging by films, cloths and the like.

[0033] like Figure 4 As shown, in some embodiments, a nozzle 1504 is disposed at each end of the arc-shaped drain pipe 1503 , and the arrangement of the nozzle 1504 can enable the water on the arc-shaped drain pipe 1503 to be sprayed out quickly.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, one side of the first scraper 7 and one side of the second scraper 8 are both provided with inclined chamfered surfaces.

[0035] It should be noted that by arranging beveled surfaces on one side of the first scraper 7 and the second scraper 8, the arrangement of the beveled surfaces can enable the first scraper 7 and the second scraper 8 to form a torrent effect when rotating, causing the water flow to fluctuate, and the fluctuating water flow to impinge on foreign objects and then wash away the foreign objects, thereby avoiding clogging by foreign objects and increasing the effect of handling foreign objects. At the same time, the arrangement of the beveled surfaces can reduce the resistance of the first scraper 7 and the second scraper 8 when rotating.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
