Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a rollover protection mechanism and a water inlet base of a portable mobile fire monitor. Background Art

[0002] A fire monitor is a fire-fighting equipment that uses water as a medium to extinguish fires at a long distance. It is applicable to various places, including petrochemical enterprises, storage tank areas, aircraft hangars, warehouses, port terminals, and garages, etc.

[0003] The mobile fire monitor is applicable to the space where the fire site is far from the water source and the fire truck cannot enter. It is used to extinguish general solid material fires and oil fires, and also for the cooling of oil tanks. Usually, it is manually carried by firefighters to a suitable position, connected to the water hose for water supply, and then used for fire extinguishing. This kind of fire monitor has the characteristics of adjustable flow rate, long range, multiple functions, small volume, and easy handling, and is an ideal fire-fighting supporting product for conventional fire trucks, oil tankers, wharves and other places.

[0004] The mobile fire monitor mainly consists of a water inlet base, a monitor body, a monitor head and other mechanisms. The water inlet base is a key component connecting the fire monitor and the water supply hose; its function is to introduce multiple fire hoses into the fire monitor to ensure that the fire monitor can work normally under the rated flow rate. The water inlet base includes a water inlet interface, a water outlet interface and a safety control; the design and performance of the water inlet base are crucial to the effectiveness and safety of the fire monitor. The water inlet interface is connected to the fire hose, usually supplied by a fire hydrant, a fire truck or a fire pump. The water outlet interface is connected to the water inlet pipeline of the fire monitor, usually with quick disconnection. When the water supply pressure of the hose is relatively high, due to the characteristics of the mobile base, once it overturns, it is easy to cause personal injury or property loss, so a safety control is set. It can be folded or retracted, which is convenient for handling and rapid transfer.

[0005] The existing water inlet bases of mobile fire monitors on the market do not have a design for safety protection when they overturn. When the fire monitor ejects eccentrically or the base works on an uneven ground, the recoil force of the ejected water flow will cause a large displacement or even overturn of the fire monitor. The overturned jet flow (pressure 8 - 10 Bar, flow rate 50 - 80 L / s) will cause a great impact on surrounding objects, which can knock down an object weighing 200 KG and pose a great danger to the surrounding personnel.

[0043] The following further explains the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0044] Referring to Figures 1 to 6 As shown, an embodiment of the present utility model provides a portable mobile fire - fighting gun water inlet base, including:

[0045] A roll - over protection mechanism 1000 and a base body 2000.

[0046] The rollover protection mechanism 1000 includes: an upper cover assembly 100, an intermediate connection assembly 200, and a lower cover assembly 300. The upper cover assembly 100 includes an upper cover body 110, a fixing member 120, and a torsion spring 130; an upper mounting cavity 140 is provided at the top of the upper cover body 110, the fixing member 120 is disposed in the upper mounting cavity 140 and connected to the upper cover body 110; the torsion spring 130 is sleeved on the fixing member 120, and both ends of the torsion spring 130 abut against the inner wall of the upper cover body 110. The intermediate connection assembly 200 includes a connecting shaft 210 and a valve plate 220; a first fixed shaft 211 protruding from its outer surface is provided at the bottom end of the connecting shaft 210, and the valve plate 220 is fixedly connected to the middle of the connecting shaft 210. The lower cover assembly 300 includes a lower cover body 310 and a clamping member 320; a lower mounting cavity 311 is provided at the top of the lower cover body 310, the clamping member 320 is disposed in the lower mounting cavity 311 and connected to a side wall of the lower mounting cavity 311, and a clamping groove 321 is provided at the top of the clamping member 320. The top end of the connecting shaft 210 is connected to the upper cover body 110, and the bottom end of the connecting shaft 210 is located in the lower mounting cavity 311; the upper cover body 110 rotates until the valve plate 220 is in an open state, and the first fixed shaft 211 is clamped in the clamping groove 321.

[0047] A channel 400 is provided inside the base body 2000; at least one water inlet 500 is provided at one end of the base body 2000, and a water outlet 600 is provided on the base body 2000; the water inlet 500, the channel 400, and the water outlet 600 are interconnected; a through hole 700 is provided on the wall of the base body 2000.

[0048] Wherein, the connecting shaft 210 of the rollover protection mechanism 1000 is hermetically connected to the through hole 700, the valve plate 220 is disposed in the channel 400, and the valve plate 220 is used to control the on-off of the channel 400 and the water inlet 500; the upper cover body 110 is located on the upper surface of the base body 2000, and the lower cover body 310 is located on the lower surface of the base body 2000 and the lower cover body 310 is hinged to the base body 2000.

[0049] When this practical application is in use, lay the base body 2000 flat. Then connect the water inlet 500 to the water intake hose and the water outlet 600 to the body of the fire fighting water cannon. Rotate the upper cover body 110 (simultaneously, the connecting shaft 210 and the valve plate 220 also rotate) until the valve plate 220 is fully opened (for example, the upper cover body 110 rotates 90 degrees). At this time, the lower cover body 310 presses on the ground, and since the first fixed shaft 211 is stuck in the card slot 321, the valve plate 220 is kept in the open state all the time, and the water flow is unobstructed. If the fire fighting water cannon generates a large displacement or directly topples over due to the recoil force during spraying, then the lower cover body 310 and the base body 2000 will rotate and open due to the hinge, and at this time, the first fixed shaft 211 disengages from the card slot 321, and under the action of the torsion spring 130, the valve plate 220, the connecting shaft 210, and the upper cover body 110 rotate and reset, so that the water flow will be closed.

[0050] It can be seen that during the use of this embodiment, the water flow can be ensured to be unobstructed. Once it tilts or topples over, the automatic closing of the valve plate 220 can be realized, improving the safety.

The nylon sleeve 810 is sleeved on the connecting shaft 210 and connected to the through hole 700, the nylon sleeve 810 is located outside the sealing ring 820, and the nylon sleeve 810 is connected to the through hole 700. Specifically, in this embodiment, the sealing connection between the connecting shaft 210 and the through hole 700 is realized through the sealing ring 820 and the nylon sleeve 810.

[0052] Furthermore, a second fixed shaft 212 protruding from its outer surface is provided at the bottom of the connecting shaft 210; the nylon sleeve 810 of a sealing connection component 800 abuts between the valve plate 220 and the second fixed shaft 212. The nylon sleeve 810 of the other sealing connection component 800 abuts between the valve plate 220 and the fixing member 120.

[0053] Furthermore, an installation hole 121 is provided in the fixing member 120; the top end of the connecting shaft 210 is inserted into the installation hole 121 and connected to the upper cover body 110 through the first pin shaft 150. In some embodiments, connecting holes communicating with each other are provided on the upper cover body 110, the fixing member 120, and the top end of the connecting shaft 210, and the first pin shaft 150 is inserted into the connecting holes of the upper cover body 110, the fixing member 120, and the connecting shaft 210, so as to realize the connection between the connecting shaft 210 and the upper cover body 110.

[0054] Further, limiting members 160 are respectively provided at both ends of the first pin shaft 150.

Specifically, in this way, when in use, the rotation of the top cover body 110 can be realized through the first pin shaft 150 extending outside the top cover body 110, and the operation is convenient and labor-saving. When not in use, the first pin shaft 150 can be retracted into the top cover body 110.

[0055] Further, the lower cover body 310 and the base body 2000 are hinged by a pin shaft.

[0056] Further, the present application further includes a foldable gripping mechanism 900 configured to provide grip force to the base body 2000.
