Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting hose residual liquid cleaning device. Background Art

[0002] The fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. After use, the fire hose needs to be stored. However, due to the long distance of the fire hose, a large amount of residual liquid remains inside it. If the residual liquid inside is not discharged, the weight of the fire hose will be greatly increased, and it will not be easy to curl, affecting the storage speed of the fire hose.

[0003] For example, Chinese patent announcement No. CN218357039U discloses a fire hose residual liquid cleaning device. When in use, the cleaning ball is inserted into the fire hose joint and inserted into the inside of the fire hose, the inner buckle joint and the fire hose joint are rotated and buckled, and the compression spring pushes the sealing gasket of the inner buckle joint against the sealing gasket inside the fire water pipe joint. At this time, the oxygen cylinder valve is opened, and a small amount of high-pressure oxygen enters the annular groove of the inner sleeve through the air hole. The high-pressure oxygen entering the annular groove pushes the annular piston, and the annular piston pushes the sealing gasket through the connecting sleeve to fit tightly with the sealing gasket inside the fire water pipe joint, thereby improving the sealing performance of the inner buckle joint and the fire hose joint. Most of the high-pressure oxygen enters the fire hose, pushing the cleaning ball to move along the fire hose to squeeze out the residual liquid in the fire hose. When the air pressure that pushes the cleaning ball is too high, the exhaust valve can discharge part of the gas to reduce the air pressure.

[0004] However, the fire hose residual liquid cleaning device in the above application uses high-pressure oxygen to push the cleaning ball to squeeze out the water inside the fire hose. However, when the fire hose is in use, its outer surface will be stained. If it is not cleaned, the hose may be scratched after being rolled up. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a fire hose residual liquid cleaning device. Utility Model Content

[0006] The purpose of the utility model is to provide a fire hose residual liquid cleaning device to solve the problem that the fire hose residual liquid cleaning device proposed in the above-mentioned background technology uses high-pressure oxygen to push the cleaning ball to squeeze out the water inside the fire hose, but the outer surface of the fire hose will be stained when in use. If it is not cleaned, the hose may be scratched after being rolled up.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire hose residual liquid cleaning device, comprising a vehicle plate and universal wheels, wherein the four universal wheels are respectively fixedly connected to the four corners of the lower surface of the vehicle plate, and the upper surface of the vehicle plate is provided with a cleaning device and a residual liquid cleaning device.

[0008] The cleaning device includes a bearing seat, a cleaning roller, a stretching assembly, and a fixed bearing. The two bearing seats are respectively fixedly connected to the front and rear ends of the right side of the upper surface of the vehicle plate. The cleaning roller is rotatably connected to the inside of the bearing seat through a rotating shaft. The two groups of stretching assemblies are respectively installed on the top of the bearing seat. The two fixed bearings are respectively fixedly connected to the top of the stretching assembly. The cleaning roller is also rotatably connected to the inside of the fixed bearing.

[0009] A further improvement is that the stretching assembly includes a stretching spring, a limiting sleeve, and a connecting slide rod, the stretching spring is fixedly connected between the bearing seat and the fixed bearing, the limiting sleeve is installed on the top of the bearing seat and is located inside the stretching spring, the connecting slide rod is slidably connected to the inside of the limiting sleeve, and its top is fixedly connected to the fixed bearing. Before the fire hose is squeezed and discharged, the fire hose passes between two cleaning rollers, and the fixed bearing is pulled by the stretching spring, thereby pulling the cleaning roller inside the fixed bearing downward and contacting the surface of the fire hose, and the friction force of the hose is used to drive the two cleaning rollers to rotate, thereby cleaning the stains and debris on its surface.

[0010] A further improvement is that the residual liquid cleaning device includes a liquid extrusion unit and a winding unit.

[0011] The extrusion and drainage unit includes a U-shaped frame, an electric hydraulic rod, a buffer assembly, a U-shaped seat, a rotating bearing, and an extrusion roller. The U-shaped frame is installed in the middle of the upper surface of the vehicle plate, the electric hydraulic rod is installed in the top center of the U-shaped frame, the buffer assembly is installed inside the bottom of the electric hydraulic rod, the U-shaped seat is fixedly connected to the bottom of the buffer assembly, the two rotating bearings are installed on the front and rear inner walls of the U-shaped seat, and the extrusion roller is rotatably connected to the inside of the rotating bearing through a rotating shaft.

[0012] A further improvement is that rotating bearings are also installed on the front and rear sides of the middle part of the U-shaped frame, and a squeezing roller is also installed inside it. When the fire hose passes over the squeezing roller in the middle part of the U-shaped frame, the electric hydraulic rod is started to drive the U-shaped seat to move downward, thereby driving the squeezing roller inside the U-shaped seat to move downward to squeeze the fire hose between the two squeezing rollers, and under the pulling of the winding unit, the remaining liquid inside the fire hose is squeezed out.

[0013] A further improvement is that the buffer assembly includes a sliding cavity, a flexible spring, a sliding rod, and an electric contact.

When the U-shaped seat moves downward and the extrusion roller inside it contacts the fire hose, the thrust generated by the extrusion of the two pushes the sliding rod to slide into the inside of the sliding cavity and squeeze the flexible spring until the two electric contacts contact each other and send out an electrical signal, thereby stopping the electric hydraulic rod from moving downward in time to avoid excessive downward movement and causing the fire hose to tear.

[0014] A further improvement is that the winding unit includes a mounting platform, a winding motor, a fixed bearing seat, a rotating shaft, a winding wheel, and a winding rod. The mounting platform is installed at the rear end of the left side of the upper surface of the vehicle plate, the winding motor is installed at the top of the mounting platform, and the fixed bearing seat is installed at the top front end of the mounting platform. The rotating shaft is connected to the output end of the winding motor and is rotatably connected to the inside of the fixed bearing seat.

[0015] A further improvement is that the fixed baffle is sleeved on the winding rod, the outer surface of the winding rod is provided with an external thread, the locking nut is threadedly connected to the winding rod, one end of the fire hose is wrapped around the winding rod, and then the fixed baffle is sleeved on the winding rod until the fire hose is fixed, and then the locking nut is screwed on, and then the winding motor is started to drive the rotating shaft to rotate inside the fixed bearing seat, thereby driving the winding wheel to rotate, so as to reel in the fire hose, which is more convenient and quick to use.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The fire hose residual liquid cleaning device, before squeezing the fire hose to drain the liquid, the fire hose passes between two cleaning rollers, and pulls the fixed bearing through the tension spring, thereby pulling the cleaning roller inside the fixed bearing to move downward and contact the surface of the fire hose, and uses the friction force pulled by the water hose to drive the two cleaning rollers to rotate, thereby cleaning the stains and debris on the surface.

[0018] 2. The fire hose residual liquid cleaning device, when the fire hose passes over the squeezing roller in the middle of the U-shaped frame, starts the electric hydraulic rod to drive the U-shaped seat to move downward, thereby driving the squeezing roller inside the U-shaped seat to move downward to squeeze the fire hose between the two squeezing rollers, and under the pulling of the winding unit, the residual liquid inside the fire hose is squeezed out.

[0019] 3. In the fire hose residual liquid cleaning device, when the U-shaped seat moves downward and the squeezing roller inside it contacts the fire hose, the thrust generated by the squeezing of the two pushes the sliding rod to slide into the inside of the sliding cavity and squeezes the flexible spring until the two electrical contacts contact each other and send out an electrical signal, thereby stopping the electric hydraulic rod from moving downward in time to avoid excessive downward movement, which may cause the fire hose to tear.
