Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to an outdoor fire hydrant with a lifting structure. Background Art

[0002] Outdoor fire hydrants are a type of fixed firefighting tool. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses or water guns to extinguish fires. They are one of the important firefighting facilities for fighting fires. They are generally installed on the sidewalks with two plates on the road.

[0003] When existing outdoor fire hydrants are in use, they are usually buried on the side of the sidewalk and connected to underground water pipes. Pedestrians may be tripped by the fire hydrants due to lack of observation. In addition, the fire hydrants are exposed to the outside and are easily knocked by external impacts, affecting subsequent normal use. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, an outdoor fire hydrant with a lifting structure includes a fire hydrant body 2 installed in a receiving well on the ground 1, and the bottom end of the fire hydrant body 2 is connected to an underground water pipe 7 through a corrugated pipe 6;

[0024] A mounting block is provided on one side close to the fire hydrant body 2, and the mounting block is buried in the ground 1, a movable groove is provided on the top of the mounting block, and a fixed block 8 is slidably installed inside the movable groove, a movable block 3 is fixedly connected to the upper position of one side of the fire hydrant body 2, a fixed groove matching the movable block 3 is provided on one side of the mounting block close to the fire hydrant body 2, and the movable block 3 is in the fixed groove, a limiting block 13 is fixedly connected to the lower position of the rear end of the fire hydrant body 2, a limiting groove matching the limiting block 13 is provided on the inner wall of the storage well, and the limiting block 13 is slidably installed in the limiting groove.

[0025] In this embodiment, a cover plate 11 is detachably installed on the top of the storage well, and a reflective plate 12 is provided on the top surface of the cover plate 11. By covering the cover plate 11 above the storage well on the ground 1, people can be prevented from accidentally falling.

[0026] In this embodiment, the reflector 12 is red, and reflective strips are provided on both sides of the top surface of the reflector 12. The reflector 12 is red, and reflective strips are provided on the reflector 12. The reflector 12 plays a conspicuous role, which is convenient for people to find when using it.

[0027] In this embodiment, a return spring 5 is provided at the lower position of the outer ring of the fire hydrant body 2, and the end of the return spring 5 away from the fire hydrant body 2 is fixedly connected to the mounting block through a connecting plate, the upper limit of the limit block 13 matches the top surface of the fixed block 8, and the lower limit of the limit block 13 matches the bottom surface of the fixed groove. The return elastic force of the return spring 5 can push the fire hydrant body 2 to rise, and the limit block 13 cooperates with the upper limit and the lower limit to facilitate limiting the lifting distance of the fire hydrant body 2 and fixing it in a suitable position.

[0028] In this embodiment, magnetic blocks 1 are provided on both sides of the fixed block 8, and magnetic blocks 2 matching with magnetic blocks 1 are provided on the inner side of the movable groove. Magnetic blocks 1 and 2 attract each other to prevent the fixed block 8 from sliding when there is no external force pulling, which is convenient for personnel to adjust.

[0029] In this embodiment, a rubber sleeve is provided on the outer ring of the movable block 3, and a rubber layer 4 is provided at the joint between the fixed groove and the movable block 3. The rubber sleeve and the rubber layer 4 can improve the friction force of the movable block 3 when sliding, and avoid the movable block 3 falling directly when the force is lost, which is convenient for simple control of the lifting speed.

[0030] In this embodiment, a heating box 9 is provided on the side of the storage well away from the fixed block 8, and a temperature monitoring probe 10 is installed on the top of the heating box 9. The temperature monitoring probe 10 is used to detect the temperature of the storage well. When the temperature is low, the heating resistance wire in the heating box 9 is controlled to be energized for heating, thereby reducing the probability of water freezing in the fire hydrant body 2 and improving the use effect.

[0031] It should be noted that the utility model is an outdoor fire hydrant with a lifting structure. When in use, first, when the fire hydrant body 2 needs to be retracted into the storage well on the ground 1, the handle on the fire hydrant body 2 can be held to press the fire hydrant body 2 downward. When the fire hydrant body 2 moves downward, the movable block 3 is driven to slide on the rubber layer 4, and the limit block 13 slides in the limit groove set on the ground 1;

[0032] When the movable block 3 slides to the bottom and is at the lower limit of the limit block 13, the fire hydrant body 2 is just in a suitable position in the storage well of the ground 1, and the top surface of the movable block 3 is in contact with the bottom surface of the fixed block 8. Then the fixed block 8 can be pushed to move toward the direction of the fire hydrant body 2. The fixed block 8 plays a role in blocking the movable block 3 to prevent the movable block 3 from moving upward, and the fixed block 8 is fixed by the mounting block. At the same time, a magnetic block 2 matching the magnetic block 1 on the fixed block 8 is provided on the mounting block. The magnetic block 1 and the magnetic block 2 can attract each other to prevent the fixed block 8 from sliding when there is no external force, which is convenient for personnel to adjust.

[0033] After the fire hydrant body 2 is stored, the cover plate 11 can be placed on the ground 1 storage well as needed to prevent people from accidentally falling, and a reflector 12 is provided on the cover plate 11. The reflector 12 is red and has a reflective strip on it to facilitate subsequent search by people.

[0034] When the fire hydrant body 2 needs to be pulled out of the storage well, the fixed block 8 can be pulled away from the fire hydrant body 2 as needed to make it away from the movable block 3, and the blocking of the movable block 3 is released. Then, the personnel can hold the handle on the fire hydrant body 2 and pull the fire hydrant body 2 upward. During the pulling process, the fire hydrant body 2 is pushed up by the reset elastic force of the reset spring 5;

[0035] Because the rear end of the fire hydrant body 2 is provided with a limit block 13, after the limit block 13 moves to the upper limit position, the bottom surface of the movable block 3 just fits the top surface of the fixed block 8, and then the fixed block 8 can be pushed to the bottom of the movable block 3 again, and the fixed block 8 is stuck under the movable block 3 to prevent the movable block 3 from falling down, completing the adjustment process, and then the personnel can connect external water pipes, water guns and other tools as needed, and turn the valve on the fire hydrant body 2 to receive water;

[0036] After the fire hydrant body 2 is stored, when the temperature monitoring probe 10 detects that the temperature in the storage well is low, the heating resistor wire in the heating box 9 can be energized for heating, thereby reducing the probability of water freezing in the fire hydrant body 2 due to excessively low temperature and improving the use effect.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
