Technical Field
[0001] The utility model relates to the technical field of fire hydrants, in particular to an anti-rust fire hydrant. Background Technique
[0002] A fire hydrant is a fixed fire-fighting device. When using a fire hydrant, after connecting a water pipe to the water outlet, manually rotate a threaded rod by a rotating disk, so that a rubber block moves away from a water inlet, and thus the water coming out of the water inlet can enter the inside of the water pipe from the water outlet. The water can be carried to the position where fire extinguishing is needed through the water pipe, which is convenient for fire fighting.
[0003] The inventor found in daily work that the fire hydrant still has at least the following problems: When using a fire hydrant, it is necessary to manually rotate a threaded rod by a rotating disk to control whether the fire hydrant discharges water. However, in actual use, since most fire hydrants are installed outdoors, in rainy weather, rainwater will flow to the connection between the threaded rod and the fire hydrant body, which may cause rust at the connection, and thus affect the use of the fire hydrant to a certain extent.

When using the fire hydrant, after connecting the water pipe to the water outlet 6, manually drive the threaded rod 2 to rotate through the rotating disc 3, so that the rubber block 4 moves away from the water inlet 5, so that the water coming out of the water inlet 5 can enter the inside of the water pipe from the water outlet 6, and the water can be brought to the position where fire extinguishing is needed through the water pipe, which is convenient for fire fighting.
[0028] Refer to Figure 2 and Figure 3, the limiting device 7 includes a circular ring 701. The circular ring 701 is arranged at the top of the fire hydrant main body 1. The circular ring 701 is sleeved on the surface of the threaded rod 2. A corrugated pipe 702 is fixedly connected to the top of the circular ring 701. The corrugated pipe 702 is sleeved on the surface of the threaded rod 2. A rubber sleeve 703 is fixedly connected to the top of the corrugated pipe 702. The rubber sleeve 703 is sleeved on the top surface of the threaded rod 2. When using the limiting device 7, the circular ring 701 is arranged at the top of the fire hydrant main body 1, and the rubber sleeve 703 is sleeved on the top of the threaded rod 2. When the threaded rod 2 rotates, it drives the corrugated pipe 702 to stretch or contract, and drives the circular ring 701 to rotate on the top of the fire hydrant main body 1, thereby being able to avoid rainwater from entering the surface of the threaded rod 2 or the connection between the threaded rod 2 and the fire hydrant main body 1 to a certain extent, and thus avoiding rust at the connection to a certain extent. A first limiting groove 704 is opened at the top of the fire hydrant main body 1. A first limiting ring 705 is rotatably sleeved on the inner wall of the first limiting groove 704. The first limiting ring 705 is fixedly connected to the inner wall of the circular ring 701. When the circular ring 701 rotates on the top of the fire hydrant main body 1, the first limiting ring 705 rotates inside the first limiting groove 704, thereby well limiting the circular ring 701 at the top of the fire hydrant main body 1. A second limiting groove 706 is opened at the top of the fire hydrant main body 1. A second limiting ring 707 is rotatably sleeved on the inner wall of the second limiting groove 706. The second limiting ring 707 is fixedly connected to the bottom of the circular ring 701. A horn sleeve 708 is arranged on the surface of the circular ring 701. When the circular ring 701 rotates, the second limiting ring 707 rotates inside the second limiting groove 706, thereby being able to prevent rainwater from entering the inside of the circular ring 701 from the bottom of the circular ring 701. The function of the horn sleeve 708 makes the rainwater flow outward, thereby preventing rainwater from accumulating on the top of the fire hydrant main body 1. A fixing groove 710 is opened on the top surface of the threaded rod 2. An arc plate 709 is sleeved on the threaded rod 2. An arc bar 711 is fixedly connected to the inner wall of the arc plate 709. The arc bar 711 is slidably connected to the inner wall of the fixing groove 710. A bolt 712 is threadedly inserted through one side of the arc plate 709. A nut 713 is threadedly sleeved on the surface of the bolt 712. The nut 713 is arranged on one side of the other arc plate 709. When the rubber sleeve 703 is sleeved on the top of the threaded rod 2, the two arc plates 709 are sleeved on the surface of the rubber sleeve 703 arranged on the surface of the threaded rod 2, thereby sliding the arc bar 711 into the fixing groove 710, then passing the bolt 712 through the two arc plates 709, and then sleeving the nut 713 on the surface of the bolt 712, thereby well restricting the rubber sleeve 703 on the surface of the threaded rod 2 by the two arc plates 709.
[0029] Refer to Figure 4, the protective device 8 includes a first sponge sleeve 801 sleeved on the surface of the fire hydrant main body 1. A second sponge sleeve 802 is sleeved on the surface of the fire hydrant main body 1. When using the protective device 8, the first sponge sleeve 801 and the second sponge sleeve 802 are sleeved on the surface of the fire hydrant main body 1. Since most fire hydrants are installed by the roadside, when a pedestrian kicks the fire hydrant, the sponge sleeves play a certain buffering role, thus avoiding pedestrian injuries to a certain extent. A rectangular frame 803 is fixedly connected to one side of the second sponge sleeve 802. A connecting belt 804 is slidably connected to the inner wall of the rectangular frame 803, and the connecting belt 804 is fixedly connected to one side of the first sponge sleeve 801. Slide the connecting belt 804 into the interior of the rectangular frame 803, so that the first sponge sleeve 801 and the second sponge sleeve 802 can be well connected together. A clamping groove 805 is formed on one side of the rectangular frame 803. A clamping strip 806 is slidably connected to the inner wall of the clamping groove 805. A connecting block 807 is fixedly connected to one side of the clamping strip 806. After passing the connecting belt 804 through the rectangular frame 803, insert the clamping strip 806 into the clamping groove 805, thereby restricting the connecting belt 804 inside the rectangular frame 803. A groove 808 is formed on the top of the rectangular frame 803. A rubber strip 809 is arranged on the inner wall of the groove 808, and the rubber strip 809 is fixedly connected to one side of the connecting block 807. Set the rubber strip 809 inside the groove 808, so that the clamping strip 806 can be well restricted inside the clamping groove 805.
[0030] Working principle: When using the fire hydrant, after connecting the water pipe to the water outlet 6, manually rotate the rotating disk 3 to drive the threaded rod 2 to rotate, so that the rubber block 4 moves away from the water inlet 5, and the water coming out of the water inlet 5 can enter the inside of the water pipe from the water outlet 6. The water can be carried to the position where fire extinguishing is needed through the water pipe, which is convenient for fire fighting. When using the limiting device 7, set the circular ring 701 on the top of the fire hydrant main body 1, and put the rubber sleeve 703 on the top of the threaded rod 2. When putting the rubber sleeve 703 on the top of the threaded rod 2, put the two arc plates 709 on the surface of the rubber sleeve 703 arranged on the surface of the threaded rod 2, then slide the arc strip 711 into the fixing groove 710, and then pass the bolt 712 through the two arc plates 709, and then put the nut 713 on the surface of the bolt 712. Thus, the rubber sleeve 703 is well restricted on the surface of the threaded rod 2 by the two arc plates 709. When the threaded rod 2 rotates, it drives the corrugated pipe 702 to stretch or contract, and drives the circular ring 701 to rotate on the top of the fire hydrant main body 1, which can, to a certain extent, prevent rainwater from entering the connection between the threaded rod 2 and the fire hydrant main body 1 through the surface of the threaded rod 2. When the circular ring 701 rotates, the second limiting ring 707 rotates in the second limiting groove 706, which can prevent rainwater from entering the inside of the circular ring 701 from the bottom of the circular ring 701. The function of the horn sleeve 708 makes the rainwater flow outward, thus preventing rainwater from accumulating on the top of the fire hydrant main body 1, and to a certain extent, preventing the surface of the threaded rod 2 or the connection between the threaded rod 2 and the fire hydrant main body 1 from rusting. When using the protection device 8, put the first sponge sleeve 801 and the second sponge sleeve 802 on the surface of the fire hydrant main body 1, slide the connecting belt 804 into the rectangular frame 803, insert the clamping strip 806 into the clamping groove 805 after passing the connecting belt 804 through the rectangular frame 803, and put the rubber strip 809 in the groove 808. In this way, the clamping strip 806 can be well restricted in the clamping groove 805, and then the connecting belt 804 is restricted in the rectangular frame 803. Since most fire hydrants are set by the roadside, when pedestrians kick the fire hydrant, the sponge sleeve plays a certain buffering role, which can, to a certain extent, prevent pedestrians from being injured.
