Description

Technical Field

[0001] The utility model relates to the technical field of pressurized water supply devices, in particular to a pressurized water supply device for building fire-fighting facilities. Background Art

[0002] Building fire-fighting facilities refer to the general term of equipment and facilities such as automatic fire alarm systems, automatic sprinkler systems, and fire hydrant systems installed in buildings (structures) for preventing and extinguishing fires in buildings (structures). When actually using building fire-fighting facilities, a pressurized water supply device needs to be installed to complete the work of secondary pressurization. It has the advantages of stable structure, convenient installation, and long service life in actual use.

[0003] The existing pressurized water supply device is in a long-term unused state, and moss is likely to grow on the inner wall of the water tank. When the water supply device needs to be used urgently, the moss and sediment on the inner wall of the water tank are likely to block the water outlet, affecting disaster relief. Therefore, the water tank needs to be cleaned regularly. However, in related technologies, a scraper is mostly used to clean the moss on the inner wall, but the moss still remains in the water tank and is likely to continue to reproduce, resulting in poor cleaning effect.

[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] Example 1

[0045] Refer to Figures 1-5 , a pressurized water supply device for building fire-fighting facilities, including a main body assembly 1, and the main body assembly 1 includes: a water tank 11, the top of which is movably connected with a tank cover 12; a water outlet pipe 13, which is connected through the left side wall of the water tank 11; a centrifugal pump 14, which is connected through the water outlet pipe 13; a cleaning assembly 2 is arranged on the water tank 11, and the cleaning assembly 2 includes: a bidirectional lead screw 21, which is rotatably connected between the inner walls of the water tank 11, and the right end of the bidirectional lead screw 21 penetrates and extends to the right side of the water tank 11; a first motor 211, the output shaft of which is fixedly connected to the right end of the bidirectional lead screw 21; threaded blocks 22, symmetrically and threadedly connected to the bidirectional lead screw 21; connecting rods 23, symmetrically hinged to the tops of the threaded blocks 22, and the middle parts of the connecting rods 23 cross each other; a rotating shaft 231, rotatably connected to the middle cross-over part of the connecting rods 23; a filter screen 24, hinged to the tops of the connecting rods 23; a scraping plate 25, fixedly connected to the outer side wall of the filter screen 24, and the scraping plate 25 is slidably connected to the inner side wall of the water tank 11; a collection frame 26, clamped to the left side wall of the water tank 11; a sweeping mechanism 27, arranged on the water tank 11. The sweeping mechanism 27 includes: a lead screw 271, rotatably connected between the inner walls of the water tank 11, and the right end of the lead screw 271 penetrates and extends to the right side of the water tank 11; a second motor 272, the output shaft of which is fixedly connected to the right end of the lead screw 271; a moving block 273, threadedly connected to the second motor 272; a brush plate 274, fixedly connected to the bottom of the moving block 273; a through groove 275, opened on the left side wall of the water tank 11, and the through groove 275 is located above the collection frame 26. The outer side walls of the threaded blocks 22 are symmetrically and fixedly connected with telescopic sleeves 3, and one end of the telescopic sleeve 3 close to the inner wall of the water tank 11 is fixedly connected with the inner wall of the water tank 11.

[0046] When in use, the staff stores water in the water tank 11 through the water inlet on the box cover 12, and the staff uses the cleaning component 2 to clean the moss and impurities in the water tank 11: the staff starts the first motor 211, the first motor 211 drives the bidirectional screw rod 21 to rotate, and the threaded block 22 threadedly connected on the bidirectional screw rod 21 drives the bottom ends of the connecting rod 23 to approach each other. Since the middle parts of the two connecting rods 23 are cross-connected by the rotating shaft 231, when the bottom ends of the connecting rods 23 approach each other, the connecting rods 23 rotate along the rotating shaft 231, so that the top ends of the connecting rods 23 approach each other, and the filter screen 24 is lifted upward. When the filter screen 24 rises, it drives the impurities in the water body to move upward, and the outer scraper 25 removes the water tank 1 The moss adhered to the inner wall is scraped upwards. When the filter 24 and the scraper 25 move to the highest point, the top surface of the filter 24 contacts the brush plate 274. The cleaning mechanism 27 brushes the objects cleaned from the filter 24 and the scraper 25 into the collection frame 26, which is convenient for the staff to clean uniformly: start the second motor 272, the second motor 272 drives the screw rod 271 to rotate, and the moving block 273 threadedly connected to the screw rod 271 drives the brush plate 274 to move to the left. When the brush plate 274 moves, it sweeps the impurities on the filter 24 and the scraper 25 into the through groove 275 on the left. The impurities fall into the collection frame 26 through the through groove 275, so as to avoid the impurities remaining in the water tank 11 and affecting the cleaning effect. When the threaded block 22 moves, the telescopic sleeve 3 fixedly connected to the outside expands and contracts with the movement of the threaded block 22. When the threaded blocks 22 approach each other, the telescopic sleeve 3 between the threaded blocks 22 contracts. At the same time, the telescopic sleeve 3 connected to the threaded block 22 and the inner wall of the water tank 11 is stretched. The telescopic sleeve 3 protects the bidirectional screw rod 21 to prevent moisture from contacting the bidirectional screw rod 21 and accelerating the rust of the bidirectional screw rod 21, thereby affecting normal cleaning.

[0047] Embodiment 2

[0048] On the basis of the first embodiment, an auxiliary function is added.

[0049] See also Figures 1-5 The inner wall of the water tank 11 is fixedly connected with an optical axis 276, and the optical axis 276 passes through the brush plate 274, and the brush plate 274 is slidably connected to the optical axis 276. The through groove 275 and the collecting frame 26 both have inclined surfaces. The connecting rod 23 and the rotating shaft 231 can be made of stainless steel.

[0050] When the moving block 273 drives the brush plate 274 to move, the brush plate 274 slides on the optical axis 276. The optical axis 276 increases the stability of the brush plate 274 during movement, enabling the brush plate 274 to fit the filter screen 24 and the scraper 25 during movement, enhancing the cleaning effect of the brush plate 274. The through groove 275 and the inclined surface on the collection frame 26 accelerate the speed of impurities entering the collection frame 26 through the through groove 275, reducing the probability of impurities accumulating at the through groove 275. The connecting rod 23, the rotating shaft 231 is in contact with water, and the stainless steel material prevents the connecting rod 23 and the rotating shaft 231 from rusting, thus avoiding the problem of affecting the normal cleaning efficiency of the filter screen 24 and the scraper 25.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
