Technical Field

[0001] This utility model relates to the field of fire hydrant well technology, specifically a fire hydrant well that is easy to access for maintenance. Background Technology

[0002] Fire hydrant wells are wells where outdoor fire hydrants are installed. They are mainly used for fire trucks to draw water and for directly connecting fire hoses and nozzles to extinguish fires. They are usually located in factory areas, warehouse areas, commercial areas, and large public buildings to facilitate the timely connection of fire-fighting equipment in the event of a fire.

[0003] Existing fire hydrant wells are equipped with ladders inside for easy access by maintenance personnel. However, the ladders are usually located at the well opening, which takes up space inside the well and limits the range of movement for maintenance personnel, making maintenance inconvenient. In addition, the well covers are quite heavy and require tools to open. Therefore, further improvements are needed. Utility Model Content

[0005] As an optimization, the transmission component includes a lower support fixedly installed on the bottom side of the well base and an upper support fixedly installed on the bottom side of the fire hydrant. The end of the lower support is rotatably connected to a connecting seat one, and the end of the upper support is rotatably connected to a connecting seat two. An electric push rod is fixedly installed between the connecting seat one and the connecting seat two.

[0006] As an optimization, the lower support is L-shaped, and the telescopic end of the electric push rod is hinged to the horizontal end of the lower support through a connecting seat.

[0007] As an optimization, the electric actuator is tilted at 10° after the manhole cover is closed.

[0008] As an optimization, the support includes a slide block slidably connected inside the slide plate, a connecting rod rotatably connected to the right side of the slide block, a fixing seat fixedly installed on the inner wall of the well body corresponding to the position of the connecting rod, and the other end of the connecting rod rotatably connected inside the fixing seat. A sliding groove is provided through the side of the slide plate, and a fastener is screwed into the inner side of the slide block corresponding to the sliding groove.

[0009] As an optimization, the fastener consists of a threaded connection and a positioning part. The threaded connection is rotatably inserted into the interior of the slide block, and the positioning part abuts against the front of the slide block on both sides of the slide groove.

[0016] 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.

[0017] Please see Figure 1 A fire hydrant well for easy access and maintenance includes a well body 1 and a fire hydrant 2. The fire hydrant 2 is fixedly installed inside the well body 1. A well seat 3 is fixedly installed inside the top of the well body 1. A well cover 4 is hinged to the top of the well seat 3. A transmission component for automatically opening and closing the well cover 4 is provided at the bottom of the well seat 3. A slide rail 5 is fixedly installed on one side of the top wall of the well body 1. A cross slider 6 is slidably connected inside the slide rail 5. A movable ladder 7 is fixedly installed on the bottom side of the cross slider 6. A support component for supporting and positioning the movable ladder 7 is provided between the back side of the movable ladder 7 and the inner wall of the well body 1. Please see Figure 2-3 The transmission components include a lower support 8 fixedly installed on the bottom side of the manhole base 3 and an upper support 9 fixedly installed on the bottom side of the fire hydrant 2. The end of the lower support 8 is rotatably connected to a connecting seat 10, and the end of the upper support 9 is rotatably connected to a connecting seat 2 11. An electric push rod 12 is fixedly installed between the connecting seat 10 and the connecting seat 2 11. The lower support 8 is L-shaped. The telescopic end of the electric push rod 12 is hinged to the horizontal end of the lower support 8 through the connecting seat 10. After the manhole cover 4 is closed, the electric push rod 12 is inclined at 10°. By starting the electric push rod 12 to extend and retract, the manhole cover 4 can be lifted upward or the manhole cover 4 can be fastened to the top of the manhole base 3 to close. Please see Figure 4The support includes a slide block 14 slidably connected inside the slide plate 13. A connecting rod 15 is rotatably connected to the right side of the slide block 14. A fixing seat 16 is fixedly installed on the inner wall of the well body 1 corresponding to the position of the connecting rod 15, and the other end of the connecting rod 15 is rotatably connected inside the fixing seat 16. A slide groove 17 is opened through the side of the slide plate 13, and a fastener 18 is screwed into the slide groove 17 inside the slide block 14. The fastener 18 consists of a threaded connection part and a positioning part. The threaded connection part is rotatably inserted into the interior of the slide block 14, and the positioning part abuts against the front of the slide plate 13 on both sides of the slide groove 17. A rubber sleeve is fitted on the outside of the positioning part, and several raised strips for increasing friction are fixedly installed on the outside of the rubber sleeve. By sliding the slide block 14 downward until it abuts against the fastener 18, the slide block 14 will be stuck in the bottom of the slide plate 13. Then, by screwing the fastener 18 into the slide block 14, it can be pressed against the outer surface of the slide plate 13, thereby playing a fixed and limiting role. The movable ladder 7 can be positioned from the bottom, improving safety.

[0018] During maintenance, the manhole cover 4 can be lifted from one end of the lower support 8 by activating the electric push rod 12, causing the electric push rod 12 to rotate around the end of the connecting seat 10, which will lift the manhole cover 4 upwards, making it convenient for maintenance personnel to enter. The movable ladder 7 allows maintenance personnel to climb down into the fire hydrant well, and then push the cross slider 6 to slide along the inner wall of the slide rail 5, so that the movable ladder 7 is close to the inner wall of the well body 1, which does not occupy the space inside the fire hydrant well, thus making it convenient for maintenance personnel to carry out maintenance. After maintenance, by pulling out the movable ladder 7, the slide block 14 will slide down along the inner wall of the slide plate 13, which will cause the connecting rod 15 to deflect downward around the fixed seat 16. Then, by turning the slide block 14, the positioning part of the fastener 18 will be pressed tightly against the outside of the slide plate 13 at the slide groove 17, which will play a fixed and limiting role, making the movable ladder 7 more stable and preventing accidents when maintenance personnel climb it.

[0019] In summary, this fire hydrant well, which is convenient for access and maintenance, allows the movable ladder 7 to be pushed so that the cross slider 6 can slide along the inner wall of the slide rail 5. This allows the movable ladder 7 to be moved to one side of the inner wall of the fire hydrant well, thereby minimizing the area occupied, increasing the range of movement for workers inside the well, and facilitating maintenance personnel to operate inside the well.

[0020] When the movable ladder 7 is pushed closer to the inner wall of the well body 1, the slide 14 will slide along the inner wall of the slide plate 13, which will in turn cause the connecting rod 15 to rotate around the fixed seat 16. Therefore, the connecting rod 15 will not hinder the movable ladder 7 from moving towards the inner wall of the well. When the movable ladder 7 is pulled, the slide 14 will slide into the bottom of the slide plate 13. Then, by tightening the fastener 18, the movable ladder 7 can be fixed in place, which can improve the stability of the movable ladder 7 and prevent accidents when maintenance personnel climb it.
