Description

Technical Field

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

[0002] When a fire occurs, taking water to extinguish the fire is the fastest way to extinguish the fire. However, due to the incomplete firefighting facilities in some areas and the inability of fire trucks to enter the nearby area to extinguish the fire, a hand-lifted motor pump is usually used to take water nearby to extinguish the fire. Water is taken through a water intake device. Since there are usually some plastic garbage and other objects in the water area, when the plastic garbage blocks the water intake device, it needs to be cleaned;

[0003] For example, a Chinese patent with patent number CN220225549U discloses a fire-fighting water intake device, which relates to the field of fire protection. The utility model includes a shell, a cover plate is installed on one side of the shell, and a rotating assembly is provided on the outer wall of the shell; the utility model is provided with a rotating assembly, and when it is necessary to scrape off impurities attached to the surface of the filter screen, the motor can be started, and the motor can drive the gear to rotate, and the gear drives the ring gear to rotate, and the ring gear drives the first scraper and the second scraper to rotate, and the first scraper can scrape off impurities attached to the filter screen on the outer wall of the shell, and the second scraper can scrape off impurities attached to the filter screen on one side of the cover plate after rotating, thereby improving the cleaning efficiency of impurities on the surface of the filter screen. At the same time, when the second scraper rotates, it will drive the storage rod to rotate, and because the plastic bag is hung on the hanging plate, one end of the storage rod will pass through the plastic bag, and when the storage rod rotates, it can drive the hung plastic belt to rotate, so that the plastic bag is rolled up or the plastic bag is thrown away due to the action of centrifugal force;

[0004] However, in the prior art, when the plastic bag completely covers the shell, the scraper is also located in the plastic. Even if the scraper rotates, the plastic bag covering the shell cannot be cleaned, and the plastic bag cannot be cleaned, thereby affecting the water intake effect. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-5 As shown, a fire-fighting water inlet includes a shell 1 in the shape of a cylinder, a plurality of water holes 11 are evenly opened on the surface of the shell 1, a filter cartridge 12 is arranged in the shell 1, a connecting member 13 is fixedly connected between the filter cartridge 12 and the upper part of the shell 1, a cleaning member 14 is slidably connected to the outer side of the cylinder of the shell 1, and the cleaning member 14 is assembled and connected with a driving mechanism 2, and the driving mechanism 2 is arranged between the upper part and the bottom part of the shell 1.

[0026] According to the technical solution of this embodiment, water taken in by the water inlet and water extractor enters through the water hole 11 on the surface of the shell 1, the filter cartridge 12 filters impurities in the water, the connecting piece 13 is used to connect the water inlet and water extractor with the water inlet pipe, the cleaning piece 14 slides up and down on the outside of the shell 1 to clean the shell 1, and the driving mechanism 2 is used to drive the cleaning piece 14 to move up and down.

[0027] Reference Figure 2 The connecting member 13 includes a circular ring portion 131 and a threaded connecting portion 132 . The circular ring portion 131 is fixedly connected to the upper end surface of the housing 1 . The threaded connecting portion 132 is fixedly connected to the circular ring portion 131 and is located in the middle of the circular ring portion 131 .

[0028] In this embodiment, the connecting piece 13 is used to connect the water intake device with the water intake pipe.

[0029] Reference Figure 2 : The outer annular array of the threaded connection part 132 of the connecting member 13 has a plurality of rotating rods 133.

[0030] In this embodiment, the rotating rod 133 is used to facilitate tightening the threaded connection part 132 and the water intake pipe.

[0031] Reference Figure 2 The driving mechanism 2 includes a motor 21 and a screw 22. Two connecting plates 23 are symmetrically provided at the bottom of the shell 1. The motor 21 is assembled and connected to the connecting plate 23 on one side. The output shaft of the motor 21 is transmission-connected to the screw 22. A threaded sleeve 144 is fixedly connected to one side of the cleaning member 14. The threaded sleeve 144 is threadedly connected to the screw 22. The connecting member 13 is fixedly connected to two symmetrically arranged positioning plates 15. The upper end of the screw 22 is rotationally connected to the positioning plate 15 on one side.

[0032] In this embodiment, it should be noted that the water inlet and outlet device has its own power supply, and the motor is powered by its own power supply. The rotation of the motor 21 drives the screw 22 to rotate, and the cleaning part 14 is slidably connected to the shell, so the cleaning part 14 will not rotate around the center of the screw 22. When the screw 22 rotates, the screw 22 drives the cleaning part 14 to move up and down, and the cleaning part 14 cleans the plastic bag attached to the shell.

[0033] Reference Figure 3 The other side of the cleaning member 14 is slidably connected with a slide bar 16, and the upper end and the lower end of the slide bar 16 are fixedly connected to the positioning plate 15 and the connecting plate 23 on the other side respectively.

[0034] In this embodiment, the cleaning member 14 is slidably connected to the slide rod 6, which can prevent the cleaning member 14 from tilting.

[0035] Reference Figure 4 : The cleaning member 14 includes a circular ring plate 141, an upper cleaning rod 142 and a lower cleaning rod 143. The inner ring of the circular ring plate 141 is slidably connected to the shell 1, the upper cleaning rod 142 is fixedly connected to the upper surface of the circular ring plate 141, and the lower cleaning rod 143 is fixedly connected to the lower surface of the circular ring plate 141.

[0036] In this embodiment, the circular plate 141 moves up and down to clean the plastic bag close to the shell 1 to ensure smooth water inlet to the water inlet. When the circular plate 141 drives the lower cleaning rod 143 to move downward, the lower cleaning rod 143 can clean the plastic bag covering the shell 1 and make the plastic bag separate from the shell 1.

[0037] Reference Figure 4 : The number of the upper cleaning rods 142 and the number of the lower cleaning rods 143 are both four, and the four upper cleaning rods 142 and the four lower cleaning rods 143 are all arranged in a circular array.

[0038] In this embodiment, when the circular plate 141 moves upward, the upper cleaning rod 143 is used to clean the plastic bags attached to the top of the circular plate 141 .

[0039] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
