Description
Technical Field
The invention relates to the technical field of fire water monitor, in particular to a fixed fire water monitor.
Background
Nowadays, due to the social development, power equipment and the daily increase, the fire easily occurs when the power equipment breaks down, once the fire is not processed in time, immeasurable property loss can be brought, people generally set a fixed fire water monitor at the place where the fire easily occurs, the so-called fire water monitor is a fire extinguishing device which uses water as a medium and remotely extinguishes the fire, and the monitor is suitable for the places such as petrochemical enterprises, tank storage areas, hangars, warehouses, ports and docks, garages and the like, and is more ideal vehicle-mounted fire monitor of a fire truck; there is certain drawback current fixed fire water monitor when using, probably has the relatively poor condition of leakproofness in the junction with the fire control area to lead to its internal pressure not enough, can't strengthen pressure through other modes when pressure is not enough, and can't make rivers restraint concentrated under the less condition of water pressure, thereby indirect reinforcing water pressure has brought certain adverse effect for in-service use, for this reason, we provide a fixed fire water monitor.
Chinese patent (application number: 2017214539793) discloses a fixed fire water monitor, including the installation base, the fixed surface of installation base installs sealing coil, the inside fixed mounting of the sealing coil of installation base surface has the fire water pipe connector, the upper end fixed mounting of installation base has the connection water pipe No. one, and the fixed surface of connection water pipe has the pressure boost hole, the upper end fixed mounting of connection water pipe has the connection water pipe No. two. This application can guarantee the leakproofness of fire hose connector department through installing sealing coil in fire hose connector department, and the difficult condition that takes place to leak water and lead to water pressure to reduce takes place to can be its pressure boost through other machinery in pressure boost hole when water pressure is not enough, and make rivers restraint more concentrate through the reposition of redundant personnel when water pressure is not enough, bring better use prospect. But current fixed fire water monitor lacks the suppression to recoil when the water spray, and the too big problem of recoil when can lead to it to open also has the risk of causing the injury to the user simultaneously.
Therefore, the fixed fire water monitor is designed, the hollow box body can move against the elastic force of the spring when the water monitor head generates recoil force through the arrangement of the sliding block, the hollow box body and the spring, the water monitor head is damped in a spring compression mode, and damage to a user due to overlarge impact force is avoided.
Disclosure of Invention
The invention provides a fixed fire water monitor, which aims to make up the defects of the prior art and solve the problem that the recoil is too large when the existing fixed fire water monitor is opened due to the lack of restraint on recoil when spraying water.
The technical scheme adopted by the invention for solving the technical problems is as follows: a fixed fire monitor comprises a monitor head and a base, wherein two groups of vertical plates are arranged on the base at intervals in the front and back direction, a mounting frame for fixing the monitor head is arranged between the vertical plates, and the front side and the back side of the mounting frame are respectively and rotatably connected with the vertical plates on the corresponding sides through rotating shafts; a through hole matched with the water cannon head is formed in the mounting frame, the water cannon head is arranged on the left and right sides, and the middle of the water cannon head is arranged in the through hole; a water inlet is formed in the right side of the lower end of the water cannon head, and a water spraying section with the inner diameter gradually reduced is arranged on the left side of the water cannon head; a blocking block is arranged on the right side of the base, an arc-shaped surface is arranged on one side, facing the water cannon head, of the blocking block, and the arc-shaped surface and the rotating shaft are coaxially arranged; a sliding block capable of sliding up and down along the arc-shaped surface is arranged between the arc-shaped surface and the right side surface of the water cannon head, a sinking groove extending rightwards is formed in the left side surface of the sliding block, a hollow box body abutting against the right side surface of the water cannon head is arranged in the sinking groove, and a spring is arranged between the hollow box body and the bottom surface of the sinking groove; the fixed multiunit guide bar that is provided with on the slider left surface of heavy groove periphery, the guide bar just passes the mounting bracket along water cannon head periphery equipartition and extends to the mounting bracket left side, the correspondence is provided with the guiding hole that matches with the guide bar on the mounting bracket.
