DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with the embodiments.
[0020] See also Figure 1-3 The utility model provides an anti-collision ground fire hydrant, including a bolt body 1, water outlet pipes 2 connected to the inside of the bolt body 1 are opened on the top of both sides of the bolt body 1, a first sealing cover 3 is threadedly connected to the water outlet of the water outlet pipe 2, a water suction pipe 4 is opened on one side of the bolt body 1, a second sealing cover 5 is threadedly connected to the water outlet of the water suction pipe 4, the water suction pipe 4 is located below the water outlet pipe 2, a top cover 6 is fixedly connected to the top of the bolt body 1, and a valve port 7 is arranged on the top of the top cover 6.
[0021] Further Figure 2 and Figure 3 As shown, it is worth explaining in detail that two parallel fixed plates 8 are fastened and sleeved on the outer surface of the bolt body 1, and telescopic rods 9 are fixedly connected to the outer surfaces of both sides and the front and rear ends of the fixed plates 8, and an arc-shaped anti-collision plate 10 is fixedly connected to the outer surface of the output end of the telescopic rod 9. A first compression spring 11 is sleeved on the telescopic rod 9, and one end of the first compression spring 11 is fixedly connected to the fixed plate 8, and the other end of the first compression spring 11 is fixedly connected to the inner surface of the arc-shaped anti-collision plate 10.
[0022] Further Figure 2 As shown, it is worth explaining in detail that four arc-shaped slide seats 12 distributed in a circle are fixedly connected to the outer surface of the bolt body 1, a slide groove 13 is opened on one side of the arc-shaped slide seat 12, a guide rod 14 is fixedly connected in the slide groove 13, a slide block 15 is slidingly sleeved on the outer surface of the guide rod 14, a second compression spring 16 is sleeved on the guide rod 14, one end of the second compression spring 16 is fixedly connected to the bottom of the slide groove 13, and the other end of the second compression spring 16 is fixedly connected to the outer surface of the bottom of the slide block 15.
[0023] Further Figure 1 and Figure 2 As shown, it is worth to explain in detail that a connecting rod 17 is hinged between the outer surface of one side of the slider 15 and the inner surface of the arc-shaped anti-collision plate 10, and a plurality of buffer holes 18 are evenly opened inside the arc-shaped anti-collision plate 10.
[0024] This solution has the following working process: when the ground fire hydrant is hit, the arc-shaped anti-collision plate 10 protects the bolt body 1. The four arc-shaped anti-collision plates 10 arranged outside the bolt body 1 are made of rigid material to prevent the impact force generated during the collision from directly acting on the bolt body 1, thereby protecting the bolt body 1 of the fire hydrant.
[0025] The impact force is buffered for the first time through the buffer hole 18 on the arc-shaped anti-collision plate 10. When the arc-shaped anti-collision plate 10 is moved under force, the telescopic rod 9 and the first compression spring 11 are compressed under force to achieve the second buffering treatment. The arc-shaped slide seat 12 fixedly connected to the outer surface of the bolt body 1 is hinged to the arc-shaped anti-collision plate 10. When the arc-shaped anti-collision plate 10 moves, the second compression spring 16 in the arc-shaped slide seat 12 is compressed under force to perform the third buffering treatment, thereby achieving the effect of the arc-shaped anti-collision plate 10 buffering the impact force when the fire hydrant is hit.
[0026] According to the above working process, it can be known that: by arranging arc-shaped anti-collision plates 10 on the outside of the fire hydrant, the bolt body 1 is protected. The four arc-shaped anti-collision plates 10 are made of rigid material to prevent the impact force generated during collision from directly acting on the bolt body 1, thereby protecting the bolt body 1 of the fire hydrant and effectively avoiding the problem of poor anti-collision performance of ground fire hydrants.
[0027] Through the buffer hole 18 opened on the arc-shaped anti-collision plate 10, the impact force during the collision is buffered for the first time. Through the action of the telescopic rod 9 and the first compression spring 11, the impact force during the collision is further buffered. Through the action of the second compression spring 16, the buffering effect of the arc-shaped anti-collision plate 10 on the impact force when the fire hydrant is hit is further improved, which effectively avoids the problem that the ground fire hydrant is easily broken after being severely hit, endangering the lives of pedestrians and increasing safety hazards.
[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a warning sign 19 is fixedly connected to the outer surface of the first sealing cover 3, and two parallel reflective warning strips 20 are fixedly connected to the outer surface of the first sealing cover 3 to enhance the warning effect, and a foam protective plate 21 is fixedly connected to the outer surface of the second sealing cover 5 to enhance the anti-collision performance of the second sealing cover 5 and improve the service life of the fire hydrant.
[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the water outlet pipe 2 and the water suction pipe 4 both pass through the arc-shaped anti-collision plate 10, so that the fire hydrant will not be interfered by the arc-shaped anti-collision plate 10 during normal operation. The bottom of the hydrant body 1 is fixedly connected to a base 22, and a plurality of fixing holes 23 are evenly opened on the base 22 to facilitate the installation of the fire hydrant.
[0030] In summary: by arranging arc-shaped anti-collision plates 10 on the outside of the fire hydrant, the bolt body 1 is protected. The four arc-shaped anti-collision plates 10 are made of rigid material to prevent the impact force generated during collision from directly acting on the bolt body 1, thereby protecting the bolt body 1 of the fire hydrant and effectively avoiding the problem of poor anti-collision performance of ground fire hydrants.
[0031] Through the buffer hole 18 opened on the arc-shaped anti-collision plate 10, the impact force during the collision is buffered for the first time. Through the action of the telescopic rod 9 and the first compression spring 11, the impact force during the collision is further buffered. Through the action of the second compression spring 16, the buffering effect of the arc-shaped anti-collision plate 10 on the impact force when the fire hydrant is hit is further improved, which effectively avoids the ground fire hydrant from being easily broken after being hit violently, endangering the life safety of pedestrians and increasing safety hazards. By arranging a warning sign 19 and a reflective warning strip 20 on the first sealing cover 3 on the water outlet pipe 2, the fire hydrant has a certain warning effect, reminding passers-by and vehicles to avoid it and reduce the collision with the fire hydrant. By arranging a foam protective plate 21 on the second sealing cover 5, the anti-collision performance of the fire hydrant is improved, thereby improving the service life and practicality of the fire hydrant.
