Description

TECHNICAL FIELD

[0001] The application discloses a fire hydrant, in particular to an indoor fire hydrant. BACKGROUND

[0002] A fire hydrant is a fixed fire-fighting facility, and the main function of the fire hydrant is to control combustible materials, isolate combustion-supporting materials and eliminate ignition sources. The fire hydrant is generally a fixed water supply facility on a water supply network, and can be used for water taking by a fire truck or direct connection of a water hose for fire extinguishing. The fire hydrant belongs to basic fire-fighting equipment. The system of the fire hydrant is composed of a fire water source, a pipe network, a fire hydrant body and accessories, and one of the fire hydrants is a large-flow fire hydrant. The large-flow fire hydrant has a large diameter and a large flow rate, and has multiple interfaces, so that multiple interfaces can be connected, and water can be discharged simultaneously to improve the fire extinguishing effect. The large-flow fire hydrant can meet the fire-fighting water supply requirements of an entire factory by being arranged at a center of an indoor factory.

[0003] In the prior art, in order to avoid the fire hydrant from being moved and damaged, the fire hydrant is basically fixedly arranged to avoid being moved and damaged. The fixed arrangement can ensure that the fire hydrant can be normally used when temporary use is needed. However, because the fire hydrant is in a fixed state, if an ignition point or a point needing to be sprayed is not opposite to the arranged point, the water hose connected to the fire hydrant needs to be lengthened and bent during use, so that the use is easily affected, and the large-flow valve is more obvious. Because the large-flow valve has a large volume, the large-flow valve needs to be arranged to be convenient for use, to ensure that the large-flow valve does not block surrounding objects after being arranged according to a space structure principle, to ensure that the large-flow valve does not block installation or passing of other devices, and to ensure that the large-flow hydrant is not as widely distributed as the ordinary fire hydrant, and the large-flow hydrant is not directly opposite to an ignition point or a position needing to be used. Therefore, the water hose connected to multiple interfaces of the large-flow hydrant is more easily lengthened or bent, and the use is more affected. Therefore, the prior art improves the adaptability of the product by rotating the fire hydrant body, and the application provides another solution according to the above introduction, so that the fire hydrant body can also be rotated, and the solution is more practical.

[0024] The support assembly comprises a support rod 13 abutting against the bottom of the moving block 8, and the receiving block 6 is provided with a reset assembly for automatically resetting the valve body 1 after rotation. The reset assembly comprises a rotating wheel 16 rotatably connected with the receiving block 6, and a spring 17 for pushing the rotating wheel 16 to reset is arranged between the rotating wheel 16 and the receiving block 6. The connecting block 7 is provided with an annular groove two 18 at the rotating wheel 16, and the width of the annular groove two 18 is greater than the diameter of the rotating wheel 16. The connecting block 7 is provided with a tooth 19 engaging with the rotating wheel at the inner wall of the annular groove two 18. The receiving block 6 is provided with a pushing rod 20 abutting against the moving block 8 on the moving path of the moving block 8. The pushing rod 20 extends into the receiving block 6 from the end abutting against the moving block 8, and the middle part of the pushing rod 20 is rotatably connected with the receiving block 6. The end of the pushing rod 20 away from the moving block 8 is provided with a fixing part 21, and the pushing rod 20 is rotatably connected with the bottom of the fixing part 21. The fixing part 21 is provided with an insert part 22 embedded in the rotating wheel 16, and the insert part 22 is slidably connected with the fixing part 21. A spring two 23 is arranged between the insert part 22 and the fixing part 21. The elastic force of the spring 17 is greater than the overall gravity of the valve body 1, and the elastic force of the spring 17 cannot overcome the vertical surface blocking force of the insert part 22. One side of the insert part 22 is an arc surface, and the other side is a vertical surface.After the valve body 1 is released from the limit, the valve body 1 rotates to drive the moving block 8 to move downward, which directly abuts the push rod 20 and pushes the push rod 20 downward, so that the push rod 20 rotates at the middle and the other end of the push rod 20 rotates upward, and the fixed part 21 is embedded into the annular groove two 18, so that the valve body 1 rotates to drive the meshing rotating wheel 16 to rotate synchronously, and the rotating wheel 16 drives the bottom spring 17 to compress the force and stop after rotating to the required position, and because the moving block 8 moves downward to push the push rod 20, the fixed part 21 and the insert 22 are lifted, and the insert 22 is embedded into the gap of the rotating wheel 16, which limits the rotating wheel 16, and the insert 22 is set as an arc surface on one side and a vertical surface on the other side, so that the valve body 1 can only rotate in one direction along the arc surface of the insert 22 to push the insert 22 inward to compress the spring two 23, and the valve body 1 is provided with a prominent rotating direction mark outside to ensure that the valve body 1 can only rotate in one direction, and the reverse rotation is blocked by the vertical surface, so that the setting does not affect the rotation, and the valve body 1 is limited by the insert 22 and the spring two 23, and vice versa, after the valve body 1 rotates, the valve rod 4 is rotated to drive the valve plate 5 to move downward, the bottom connecting rod 15 is pushed downward to rotate the internal spring to compress the spring, and the sleeve 14 is pushed upward to drive the moving block 8 and the limit block 9 to move upward, but because the limit block 9 is located in the arc groove one and is misaligned with the clamping groove 10, the moving block 8 moves upward to cancel the pushing of the push block, and the spring two is provided in the middle of the push block, so that the spring two is released when the moving block 8 moves downward, and the push block is rotated to reset, and the fixed part 21 and the insert 22 are pulled downward to re-embed into the receiving block 6, so that the rotating wheel 16 can be pushed backward by the spring 17, so as to achieve the effect of automatic reset, no matter what angle the valve body 1 rotates to, after the valve plate 5 is closed, it can be automatically reset after being removed, and the insert 22 does not loosen during use, so as to achieve the effect of limiting and automatic reset, even if the user forgets to reset, the valve body 1 can also be automatically reset to avoid affecting the surrounding traffic due to the rotation angle of the valve body 1.

[0025] The bottom of the support rod 13 and the abutment plate 12 are provided with a spring 24 for pushing the support rod 13, the bottom of the support rod 13 is provided with a connecting rope 25, the connecting rope 25 extends downward away from one end of the support rod 13, penetrates through the bottom of the spring 24 and is connected with the connecting rod 15, and the abutment plate 12 is rotatably connected with a roller 26 for supporting and guiding the connecting rope 25. The sleeve assembly 14 is arranged in a staggered manner with the support rod 13, and because the connecting rod 15 is rotatably connected with the abutment block close to the sleeve assembly 14, the rotating angle of the connecting rod 15 close to the valve plate 5 is large, and the rotating angle close to the sleeve assembly 14 is small, and the moving degree is effective, and then the connecting rope 25 is connected with the connecting rod 15 close to the valve plate 5, so that the moving degree is relatively large, and after the valve plate 5 is set to move upward to cancel the compression of the connecting rod 15, the connecting rod 15 rotates along the rotating point, and the end of the connecting rod 15 close to the valve plate 5 moves upward, which synchronously pulls the sleeve assembly 14 and the support rod 13 to move downward, and because the end of the connecting rod 15 close to the valve plate 5 has a large rotating range, and the connecting rope 25 moves more, the support rod 13 moves downward more, so that the support rod 13 and the sleeve assembly 14 are flat and support the moving block 8 together, and vice versa, when the valve plate 5 is downwardly pressed to reset the connecting rod 15, the sleeve assembly 14 and the support rod 13 move upward from the flat state synchronously, first push the moving block 8 upward to the top of the arc-shaped groove one, and because the limiting block 9 is arranged in a staggered manner with the clamping groove 10, the valve plate 5 has been closed at this time, the pulling force of the connecting rope 25 disappears completely, and the sleeve assembly 14 is reset, and then the rotating wheel 16 is separated from the limiting of the plug-in assembly 22, and waits for the spring 17 to push the rotating wheel 16 to rotate and reset the valve body 1, so that the clamping groove 10 is opposite to the limiting block 9, and at this time, the limiting block 9 and the moving block 8 are separated from the blocking of the top of the arc-shaped groove one, the spring 24 at the bottom of the support rod 13 drives the support rod 13 and the sleeve assembly 14 to be arranged in a staggered manner, and pushes the moving block 8 and the limiting block 9, and the limiting block 9 is embedded into the clamping groove 10 to limit the valve body 1 again, and the height of the annular groove one 11 is greater than the height of the limiting block 9. In this way, the space height of the annular groove one 11 is increased to accommodate the movement of the moving block 8 and the limiting block 9, and the distance is prevented from being too short to cause limiting blockage. The valve rod 4 at the lower end of the valve plate 5 is provided with an extension rod 27, the extension rod 27 is provided with a connecting part 28, the connecting part 28 is provided with an annular push block 29 which is in close contact with the inner diameter of the abutment block and pushes the connecting rod 15 upward. After the valve plate 5 moves upward to cancel the compression of the connecting rod 15, the extension rod 27, the connecting part 28 and the annular push block 29 move upward synchronously, and the annular push block 29 is in close contact with the inner wall of the abutment plate 12, so that if the pushing force of the spring 17 in the connecting rod 15 is not enough to move upward, the annular push block 29 also has a pushing effect, and if the connecting rod 15 moves upward, the annular push block 29 also has a supporting effect, which avoids loosening caused by gravity or water flow, and the interval arrangement of the connecting part 28 does not block the water flow.Finally, the connecting rod 15 and the push rod 20 are provided with a hinged rod, one end of which is rotatably connected with the connecting rod 15 and the push rod 20 itself, and the other end is rotatably connected with the sleeve machine and the fixing piece 21. Thus, when the connecting rod 15 and the push rod 20 rotate, the hinged rod will rotate and move up and down. When the movement path of the sleeve machine and the fixing piece 21 is limited by the sleeve machine and the fixing piece 21, and the two ends of the hinged rod rotate, the sleeve machine and the fixing piece 21 can be moved, and the rotation of the hinged rod will not cause the problem of blockage or jamming, which will cause the sleeve machine and the fixing piece 21 to be unable to move.

[0026] Thus, after the above setting, the valve plate 5 is lifted up by rotating the outer end of the valve rod 4, so that the spring inside the connecting rod 15 is released and pushes the connecting rod 15 to rotate. The end of the connecting rod 15 abutting the valve plate 5 rotates upward, while the other end connected with the sleeve 14 moves downward. Thus, the sleeve 14 moves downward, and the connecting rod 15 also pulls the connecting rope 25 upward, causing the support rod 13 to move downward synchronously. The two move downward synchronously, and because the rotating point of the connecting rod 15 is close to the sleeve 14, the rotating amplitude of the connecting rope 25 connected with the sleeve 14 is larger. Thus, the connecting rope 25 is pulled to a larger extent in the synchronous state, and the support rod 13 moves downward faster, so that the support rod 13 is leveled with the sleeve 14 to support the moving block 8 downward together, and the spring 24 at the bottom of the support rod 13 is compressed. After the moving block 8 drives the limiting block 9 to disengage from the clamping groove 10, the limiting block 9 moves downward and enters the annular groove 11, so that the support rod 13 is leveled with the sleeve 14, thereby releasing the restriction on the valve body 1, allowing the valve body 1 to rotate. After the moving block 8 continues to move downward, the bottom abuts the push rod 20 connected with the bearing block 6, pushing the push rod 20 downward. Thus, the push rod 20 rotates, and the other end connected with the fixed part 21 is lifted up, driving the insert 22 in the fixed part 21 to move upward synchronously. The insert 22 is opposite to the rotating wheel 16 and is embedded between the two teeth of the rotating wheel 16, thereby restricting the valve body 1. The valve body 1 is provided with a rotating direction marker, so that when the angle needs to be adjusted, the valve body 1 can be pushed along the rotating direction marker, and the restriction force of the insert 22 is greater than the weight of the valve body 1 and the impact of the water flow, thereby ensuring that it does not loosen during use. When it needs to be rotated, the pushing force is greater than the resistance of the spring 23 and the insert 22, so it can be rotated. When it stops, it does not need to be fixed, which is convenient and fast. When rotating, the insert 22 is pushed by the rotating wheel 16 along the arc surface to move the spring 23, so that it can be rotated conveniently. By opening the valve plate 5, the limiting can be released, and by opening the valves of each drain 3 one by one, the desired direction can be used, avoiding the situation that the water hose is folded and blocked or the water is blocked.Conversely, after use, after the water is used up, by rotating the valve rod 4, the valve plate 5 is lowered again to reset the connecting rod 15, and the spring inside the connecting rod 15 is compressed, and the connecting rod 15 resets to push the sleeve 14 and the support rod 13 upwards again, and the connecting rope 25 is also relaxed to cancel the pulling, at this time the spring 24 will also slowly push the support rod 13 upwards, whereby the support rod 13 and the sleeve 14 are synchronized to rise first, then the support rod 13 will reset and push the moving block 8 upwards first, while the sleeve 14 moves slowly, and when the support rod 13 pushes the moving block 8 and the limit block 9 abuts the top of the arc-shaped groove 1, if the sleeve 14 has not reached, when the connecting rod 15 is completely reset, the sleeve 14 is also attached to the bottom of the moving block 8, and because the top of the arc-shaped groove 1 blocks, the support rod 13 cannot continue to move upwards, whereby the spring 2 inside the push rod 20 between the abutment block 6 will also push the push rod 20 to reset, and drive the fixed part 21 and the insert 22 to reset, cancel the restriction on the rotating wheel 16, at this time the rotating wheel 16 is compressed against the clockwork 17 after the valve body 1 is rotated, at this time the clockwork 17 will push the entire rotating wheel 16 to reset after being released from the limit, and the valve body 1 is rotated by the rotating wheel 16 driving the teeth 19 in the annular groove 2 18 of the valve body 1, thereby achieving the effect of automatic reset. When the rotating reset is completed, the clamping groove 10 is opposite to the limit block 9, at this time the spring 24 pushes the support rod 13 to drive the moving block 8 to move upwards, so that the moving block 8 drives the limit block 9 to be embedded in the clamping groove 10, to reset the valve body 1, whereby through the above setting, only when it is needed to use and the valve rod 4 is opened, the valve body 1 can be rotated, in the normal state, it is fixed and will not deviate to hinder the setting position from passing, secondly, it can be automatically released from the limit by opening, and a larger force can be automatically rotated according to the rotating direction, and it is also ensured that it will not be affected by the water flow impact to rotate, finally, after use, after the valve plate 5 is closed, it can be automatically reset without manual reset, because the valve body 1 is arranged with space layout, it avoids the situation that no reset affects the surrounding passage, even affects the use of the surrounding setting, secondly, it also avoids the situation that the rotation causes secondary injury after impact, automatic reset can avoid the situation that no reset is caused by forgetting, automatic reset is safer and more secure, and after automatic reset, it is also automatically limited. Compared with the prior art, the practicality and adaptability are improved.
