Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, specifically a fire protection engineering water supply device. Background Technology

[0002] Fire protection engineering generally refers to the design, construction, and maintenance of fire prevention, smoke prevention, explosion protection, and fire extinguishing systems in buildings or places. Among these, fire fighting is a very important aspect of fire protection engineering. The water supply device for fire fighting is generally a fire hydrant, which is connected to the municipal water supply system to provide sufficient water supply during fire fighting.

[0003] In the prior art, Chinese patent application number CN201910802876.0 discloses a fire hydrant, including a fire hydrant body; an E-shaped tube, which consists of an upper horizontal tube, a middle horizontal tube, a lower horizontal tube, and a vertical tube, with the upper and lower horizontal tubes connected to a first opening and a second opening respectively, and the interior of the vertical tube forming a radius reduction zone corresponding to the middle horizontal tube; two filter plates are spaced apart inside the middle horizontal tube, with a waterproof and breathable membrane between the two filter plates; a shell, with a circular mounting hole on its first side, through which the middle horizontal tube extends into the shell; a sound-generating mechanism, including an outer cylinder, an inner cylinder, and a vibrating diaphragm; a sound sensor and an alarm, with the sound sensor located inside the shell, used to detect sound signals; if the detected sound signal matches a predetermined signal, an alarm signal is generated, causing the alarm to sound.

[0004] Based on the above information, it can be seen that fire hydrants in the existing technology generally require the valve body to be turned to open and close. However, in actual use, since fire hydrants are generally installed outdoors, after a long period of exposure to wind and rain, rust will appear between the rotating part of the valve body and the outer shell of the fire hydrant, making it difficult to turn and open normally when needed. Utility Model Content

[0005] The purpose of this utility model is to provide a water supply device for fire protection engineering, so as to solve the problem of corrosion affecting the opening of the rotating position mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire hydrant water supply device, comprising a fire hydrant shell with a hollow cylindrical structure, a flange-shaped mounting seat fixedly installed at the lower end of the fire hydrant shell, the mounting seat being fixedly installed to a water supply pipe buried underground using a flange, and a water outlet connector being fixedly installed on the side of the fire hydrant shell; a top cover being fixedly installed at the upper end of the fire hydrant shell using a flange, and a connecting column being rotatably installed at the middle position above the top cover, and a valve stem connecting to the valve core inside the fire hydrant shell being provided below the connecting column, and a rotating disk being fixedly installed at the upper end of the connecting column using mounting bolts; a horizontally arranged partition plate being fixedly installed at the middle position inside the top cover, and the internal space of the top cover above the partition plate being a storage compartment, and a lubrication mechanism being provided inside the storage compartment.

[0007] Preferably, the lubrication mechanism includes an application sponge fixedly mounted on the upper surface of the partition plate, and the application sponge has an overall ring structure.

[0008] Preferably, the storage compartment is filled with liquid lubricating oil, and a filling pipe for adding lubricating oil is fixedly installed on the side of the top cover.

[0009] Preferably, the lower end of the connecting column is coaxially fixedly installed with a connecting block, and the connecting block and the upper surface of the sealing cover form a through-type sliding structure.

[0010] Preferably, the lower surface of the connecting block is provided with a mating groove, and the mating groove and the mating rod form an insertion-type engagement structure, and the cross-section of the mating groove and the mating rod are both square structures.

[0011] Preferably, a reset spring is fixedly installed inside the docking groove, and the docking rod is fixedly installed at the top of the valve stem, and the docking rod slides up and down inside the docking groove.

[0012] Preferably, a sealing cap is provided on the outside of the water outlet connector, and a connecting rope is fixedly installed between the sealing cap and the water outlet connector. Reinforcing ribs with equal spacing are fixedly installed on the lower outer surface of the fire hydrant housing, and a pressure gauge is fixedly installed on the lower side of the fire hydrant housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the fire protection engineering water supply device adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The rotating disc drives the connecting column and valve stem to rotate, thereby controlling the opening and closing of the fire hydrant. When rust occurs, the rotating disc can be pressed down to make the rotating disc drive the connecting column and connecting block to move downward, thereby moving the connecting block to the position of the coating sponge. The coating sponge is used to apply lubricating oil to achieve the purpose of lubrication.

[0015] Furthermore, the mating groove at the lower end of the connecting block slides with the mating rod at the upper end of the valve stem, and can be reset by the return spring inside the mating groove, thereby providing space for the connecting column and connecting block to move up and down when the valve stem is stationary.

[0016] Furthermore, the storage compartment is filled with lubricating oil, which ensures that the application sponge in the storage compartment can always be fully saturated with lubricating oil, so that the application sponge always maintains the best application and lubrication effect.

[0017] 2. Reinforcing ribs are fixedly installed on the lower side of the fire hydrant shell. The strength of the fire hydrant shell is improved by the equally spaced reinforcing ribs, so that it can withstand greater water pressure.

[0018] Furthermore, a pressure surface is installed on the side of the fire hydrant casing to monitor the internal water pressure data in real time, thereby facilitating the inspection of the fire hydrant status at any time and avoiding insufficient water pressure when needed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-3 In order to achieve the purpose of supplying water for fire protection engineering, this embodiment provides the following technical solution, specifically disclosing: a fire hydrant shell 1 with a hollow cylindrical structure, a flange-shaped mounting seat 2 fixedly installed at the lower end of the fire hydrant shell 1, the mounting seat 2 being fixedly installed with the water supply pipe 3 buried underground using a flange, and a water outlet connector 4 fixedly installed on the side of the fire hydrant shell 1; a top cover 7 fixedly installed at the upper end of the fire hydrant shell 1 using a flange, and a connecting column 8 being rotatably installed at the middle position above the top cover 7, and a valve stem 9 connected to the valve core inside the fire hydrant shell 1 being provided below the connecting column 8, a rotating disk 10 being fixedly installed at the upper end of the connecting column 8 using mounting bolts 11, a sealing cover 5 being provided on the outside of the water outlet connector 4, and a connecting rope 6 being fixedly installed between the sealing cover 5 and the water outlet connector 4, reinforcing ribs 20 being fixedly installed at equal intervals on the lower outer surface of the fire hydrant shell 1, and a pressure gauge 21 being fixedly installed on the lower side of the fire hydrant shell 1.

[0029] During installation, the fire hydrant housing 1 is first connected and fixed to the municipal water supply pipe 3 buried underground using the mounting base 2. Then, the rotating disc 10 is fixed to the upper exterior of the connecting column 8 using the mounting bolts 11. When water supply is required, the pressure gauge 21 on the lower side of the fire hydrant housing 1 is checked to determine whether the water pressure inside the fire hydrant housing 1 meets the usage requirements. If it does, the sealing cover 5 is opened and the fire hose is connected to the outlet connector 4 (using the connecting rope 6 to prevent the sealing cover 5 from being lost). Then, the rotating disc 10 is operated to drive the connecting column 8 to rotate, which causes the connecting block 12 at the lower end of the connecting column 8 to drive the valve stem 9 to rotate, thereby controlling the valve body inside the fire hydrant housing 1. Opening the valve body allows water inside the water supply pipe 3 to flow into the fire hose through the outlet connector 4 to achieve the purpose of water supply.

[0030] Example 2: Please refer to Figures 4-7In order to achieve the purpose of lubrication and prevent interference with opening, this embodiment provides the following technical solution, which specifically discloses: A horizontally arranged partition plate 16 is fixedly installed in the middle position inside the upper cover 7, and the internal space of the upper cover 7 above the partition plate 16 is a storage chamber 17. A lubrication mechanism is provided inside the storage chamber 17. The lubrication mechanism includes an applicator sponge 18 fixedly installed on the upper surface of the partition plate 16. The applicator sponge 18 has an overall annular structure. The storage chamber 17 is filled with liquid lubricating oil. An oil filling tube 19 for adding lubricating oil is fixedly installed on the side of the upper cover 7. A connecting block 12 is coaxially fixedly installed at the lower end of the connecting column 8. The connecting block 12 and the upper surface of the upper cover 7 form a through sliding structure. A docking groove 14 is opened on the lower surface of the connecting block 12. The docking groove 14 and the docking rod 13 form an insertion engagement structure. The cross-section of the docking groove 14 and the docking rod 13 are both square structures. A reset spring 15 is fixedly installed inside the docking groove 14. The docking rod 13 is fixedly installed at the top of the valve stem 9 and slides up and down inside the docking groove 14.

[0031] When the connection between the connecting block 12 and the upper cover 7 becomes rusted after prolonged exposure to wind and rain, affecting rotation, the operator first presses down on the rotating disk 10. The rotating disk 10 then moves the connecting column 8 and the connecting block 12 downwards. At this time, the mating groove 14 at the lower end of the connecting block 12 slides relative to the mating rod 13 at the upper end of the valve stem 9, eventually moving the connecting block 12 to the inside of the coating sponge 18. The coating sponge 18 is then used to apply lubricating oil to the outside of the connecting block 12. Afterwards, the connecting column 8 and the connecting block 12 are reset under the pushing action of the return spring 15, achieving the purpose of lubrication. The coating sponge 18 is located in the storage chamber 17, and lubricating oil is added to the storage chamber 17 through the filling pipe 19. The lubricating oil is absorbed by the coating sponge 18.
