Description

Technical Field

[0001] This utility model relates to the field of fire monitor hydrant integrated machine opening and closing technology, and in particular to a fire monitor hydrant integrated machine valve core opening and closing device. Background Technology

[0002] In practical applications and emergency drills, this integrated fire monitor and hydrant machine revealed a critical structural design flaw that severely limited its performance. Specifically, the space between the water monitor's curved pipe structure and the hydrant's valve core was too short, resulting in a distance smaller than the operating length of a standard fire wrench. When rapid hydrant opening is needed to ensure water supply, the wrench, due to space constraints, cannot perform a continuous 360-degree rotation. Operators are forced to use intermittent, reciprocating "forward rotation-reverse reset" operations. This extremely cumbersome operating mode, in the time-sensitive fire emergency scenario, significantly delays the valve core's opening speed, directly preventing the hydrant from quickly dispensing water. This design flaw not only negates some of the efficiency gains from equipment upgrades but also poses a potential threat to the critical fire suppression speed, forming a technical bottleneck that urgently needs to be addressed.

[0003] Therefore, further improvements are needed. To this end, we have proposed an integrated valve core opening and closing device for fire monitor hydrants. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fire monitor hydrant integrated valve core opening and closing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire hydrant integrated valve core opening and closing device, comprising a wheel rim and a rod body, wherein multiple connecting rods are fixedly connected between the outer side wall of the top of the rod body and the inner side wall of the wheel rim, the radius of the wheel rim is smaller than the distance between the fire hydrant integrated water cannon bend and the fire hydrant valve core, a protrusion is fixed between any connecting rod and the wheel rim, a handle is rotatably connected to the upper surface of the protrusion, a retaining sleeve is fixed at the bottom of the rod body, and an inner pentagonal groove is opened on the lower surface of the retaining sleeve.

[0006] Furthermore, a circular groove is provided on the upper surface of the protrusion, and a connecting post is fixed at the bottom of the handle. The connecting post is located inside the groove and is rotatably connected to the groove through a bearing.

[0007] Furthermore, the inner pentagonal groove on the lower surface of the sleeve matches the size of the pentagonal nut on top of the fire monitor hydrant integrated valve core.

[0008] The beneficial effects of this utility model are:

[0009] In use, this invention comprises a wheel rim, a rod, a connecting rod, a handle, and a retaining sleeve. The radius of the wheel rim is smaller than the distance between the water cannon bend and the fire hydrant valve core. The inner pentagonal groove below the retaining sleeve is engaged with the fire hydrant valve core. Rotating the wheel rim using the handle causes the retaining sleeve to rotate, which in turn rotates the fire hydrant valve core, thus opening and closing the valve. Compared to a wrench, this device is more flexible, allowing for continuous rotation in emergency situations. It is easy and flexible to operate, making it ideal for use in narrow spaces between hydrants, reducing the workload for workers, and significantly increasing the opening speed of the fire hydrant valve core, resulting in faster water flow. In comparison, the wheel-type rotary wrench opens approximately 15 seconds faster than a long strip fire wrench, greatly increasing the water flow rate and improving the probability of successful fire suppression.

[0017] 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, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present utility model.

[0018] like Figures 1-4The invention relates to a valve core opening and closing device for an integrated fire monitor hydrant, comprising a wheel rim 1 and a rod 2. Multiple connecting rods 3 are fixedly connected between the outer wall of the top of the rod 2 and the inner wall of the wheel rim 1. The radius of the wheel rim 1 is smaller than the distance between the water cannon bend of the integrated fire monitor hydrant and the fire hydrant valve core. A protrusion 4 is fixed between any connecting rod 3 and the wheel rim 1. A handle 5 is rotatably connected to the upper surface of the protrusion 4. A retaining sleeve 7 is fixed to the bottom of the rod 2, and an inner pentagonal groove 71 is formed on the lower surface of the retaining sleeve 7.

[0019] A circular groove 41 is provided on the upper surface of the protrusion 4, and a connecting post 6 is fixed at the bottom of the handle 5. The connecting post 6 is located inside the groove 41, and the connecting post 6 is rotatably connected to the groove 41 through a bearing.

[0020] Therefore, when the handle 5 rotates the wheel rim 1, the handle 5 and the wheel rim 1 can rotate, reducing the rotational resistance when rotating to open the valve core, and increasing the rotational speed and effect.

[0021] The inner pentagonal groove 71 on the lower surface of the ferrule 7 matches the size of the pentagonal nut on the top of the fire monitor hydrant integrated valve core.

[0022] When in use, the inner pentagonal groove 71 at the bottom of the ferrule 7 is directly inserted into the pentagonal nut surface at the top of the fire monitor hydrant integrated valve core. Then, the handle 5 is used to rotate the wheel rim 1. The wheel rim 1 drives the rod body 2 to rotate, and the rod body 2 drives the ferrule 7 to rotate and open the fire monitor hydrant integrated valve core.

[0023] Working Principle: When this integrated fire hydrant valve core opening and closing device is in operation, firstly, the inner pentagonal groove 71 of the retaining sleeve 7 at the bottom of the rod 2 is aligned and fitted onto the pentagonal nut at the top of the fire hydrant valve core. The operator holds the handle 5 and applies rotational force. Because the radius of the wheel rim 1 is smaller than the distance between the water cannon bend and the valve core, it can rotate continuously without obstruction. The handle 5 rotates smoothly in the groove 41 of the protrusion 4 through the connecting post 6, driving the wheel rim 1, connecting rod 3 and rod 2 to rotate synchronously. Finally, the torque is accurately transmitted to the valve core through the retaining sleeve 7, realizing the rapid opening or closing of the fire hydrant valve core, solving the technical problem of the original fire wrench being unable to operate due to insufficient space.

[0024] This achievement has been put into practical application at the Fairy Lake Oil Depot. It has low modification costs and significantly accelerated the water output speed in multiple fire drills, which can quickly meet the requirements of battlefield fire fighting, greatly reduce the losses caused by fire, and achieve good social and economic benefits.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not provide exhaustive details and do not limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
