[0024] like Figures 1 to 5 As shown, the utility model provides a water flow booster device for a fire hydrant, comprising a fire hydrant body 1, a motor 2, a booster propeller 3 and a water baffle 4, the surface of the water baffle 4 is fixedly connected to the top of the inner wall of the fire hydrant body 1, the top of the inner wall of the fire hydrant body 1 is fixedly connected with a placement frame 5, the top of the back side of the fire hydrant body 1 is provided with a slot 6, the slot 6 is connected to the inner wall of the placement frame 5, the back side of the slot 6 is fixedly connected with a slide frame 7, the inner wall of the slide is slidably connected with a hatch 8, the surface of the motor 2 is movably connected to the inner wall of the placement frame 5, An auxiliary handle 9 is fixedly connected to the back of the motor 2, a support block 10 is fixedly connected to the front side of the bottom of the water baffle 4, the rear side of the surface of the booster propeller 3 is movably connected to the inner wall of the support block 10, the back of the booster propeller 3 penetrates to the top of the water baffle 4, and a docking groove 11 is provided on the back of the booster propeller 3. An air intake fan 12 is embedded in the top of the front of the fire hydrant body 1, and an exhaust fan 13 is embedded on one side of the back of the fire hydrant near the bottom of the slide frame 7. A fixing mechanism 14 is fixedly connected to the top of the hatch 8, and a docking mechanism 15 is fixedly connected to the output end of the motor 2.

[0025] refer to Figure 2 and Figure 3 The fixing mechanism 14 includes an extension rod 141, the top of the extension rod 141 is movably connected to a rotating rod 142 through an axle pin, the top of the rotating rod 142 is fixedly connected to a clamping ring 143, the top of the back side of the fire hydrant body 1 is fixedly connected to a fixing strip 144, and the inner wall of the clamping ring 143 is movably connected to the surface of the fixing strip 144.

[0026] As a technical optimization scheme of the utility model, by setting a fixing mechanism 14, when the motor 2 needs to be taken out for maintenance, the operator pulls the snap ring 143 to move the rotating rod 142 together with the extension rod 141, and moves the cabin door 8 upward along the trajectory of the slide frame 7. When the snap ring 143 moves to be flush with the fixing bar 144, the snap ring 143 is moved through the rotating rod 142 so that the snap ring 143 is engaged with the fixing bar 144, thereby limiting and fixing the cabin door 8 to facilitate subsequent operations.

[0027] refer to Figure 4 and Figure 5 The docking mechanism 15 includes a main block 151, the back of the main block 151 is fixedly connected to the output end of the motor 2, the inner wall of the main block 151 is slidably connected to a connecting block 152, the surface of the main block 151 is slidably connected to an auxiliary frame 153, the front of the connecting block 152 penetrates to the front of the auxiliary frame 153 and is slidably connected to the docking groove 11, the surface of the connecting block 152 is fixedly connected to the inner wall of the auxiliary frame 153, the front of the main block 151 is fixedly connected to a spring 154, and the other end of the spring 154 is fixedly connected to the front side of the inner wall of the auxiliary frame 153.

[0028] As a technical optimization scheme of the utility model, by setting a docking mechanism 15, after the maintenance of the motor 2 is completed, the operator puts the motor 2 back into the placement frame 5, and pushes the motor 2. When it is pushed to a certain position, the connecting block 152 contacts the boost propeller 3, and the spring 154 is squeezed and deformed, so that the auxiliary frame 153 moves backward along the trajectory of the main block 151. At the same time, the spring 154 rebounds. At this time, the boost propeller 3 is manually rotated. When the boost propeller 3 rotates to a certain extent, the rebound force of the spring 154 will move the connecting block 152 into the docking groove 11, so that the motor 2 and the boost propeller 3 are reconnected.

[0029] refer to Figure 5 A first limit block 16 is fixedly connected to the front side of the surface of the main block 151 . Six first limit blocks 16 are arranged in a ring shape and are equidistantly distributed. The back side of the first limit block 16 contacts the rear side of the inner wall of the auxiliary frame 153 .

[0030] As a technical optimization scheme of the utility model, by setting a first limit block 16, when the motor 2 is pulled out of the fire hydrant body, the main block 151 at the output end of the motor 2 limits the auxiliary frame 153 through the first limit block 16, to prevent the inertia force generated when the operator pulls the motor 2 from causing the auxiliary frame 153, which is movably mounted on the main block 151, to be detached from the main block 151 together with the connecting block 152 and fall into the fire hydrant body 1, thereby improving the stability of the auxiliary frame 153 when moving.

[0031] refer to Figure 4 A second limiting block 17 is fixedly connected to the front of the placement frame 5, and four second limiting blocks 17 are arranged and are distributed equidistantly in a rectangular shape.

[0032] As a technical optimization scheme of the utility model, by setting a second limit block 17, when the motor 2 is placed in the placement frame 5, the operator quickly pushes the motor 2 forward along the movement trajectory of the placement frame 5, and stops when it hits the second limit block 17, thereby limiting the movement trajectory of the motor 2 in the placement frame 5, preventing the operator from pushing the motor 2 out of the placement frame 5 due to improper force, causing the output end of the motor 2 to collide with the water baffle 4 and cause damage to the motor 2, thereby improving the stability of the movement of the motor 2.

[0033] refer to Figure 2 Both sides of the back side of the placement frame 5 are movably connected with a clamping strip 18 through an axle pin, and the bottom of the clamping strip 18 contacts the top of the auxiliary handle 9.

[0034] As a technical optimization scheme of the utility model, by setting the locking bar 18, when the motor 2 is placed in the placement frame 5, the operator rotates the locking bar 18 to fit with the auxiliary handle 9 to limit the motor 2, thereby preventing the vibration generated by the motor 2 when driving the boost propeller 3 from causing the motor 2 to shake and displace, causing the connecting block 152 to move together and making the connection between the motor 2 and the boost propeller 3 unstable, thereby improving the connection stability between the motor 2 and the boost propeller 3.

[0035] refer to Figure 5 A first protective net 19 is fixedly connected to the front of the air intake fan 12 , and a second protective net 20 is fixedly connected to the back of the exhaust fan 13 .

[0036] As a technical optimization scheme of the utility model, the first protective net 19 and the second protective net 20 are provided to cover and protect the intake fan 12 and the exhaust fan 13, while ensuring ventilation, preventing the intake fan 12 and the exhaust fan 13 from being accidentally touched by the operator when rotating at high speed, thereby preventing the operator from being injured and causing damage to the intake fan 12 or the exhaust fan 13, thereby improving operational safety and the service life of the intake fan 12 and the exhaust fan 13.

[0037] The working principle and use process of the utility model are as follows: when the motor 2 drives the supercharged propeller 3 during use, the intake fan 12 and the exhaust fan 13 are started at the same time, so that the intake fan 12 quickly inhales air, and the exhaust fan 13 quickly discharges the internal hot air, so as to maintain the ventilation inside the fire hydrant and reduce the heat generated by the operation of the motor 2. When the motor 2 does not need to work at ordinary times, the operator pulls the snap ring 143 to move the rotating rod 142 together with the extension rod 141, and moves the hatch 8 upward along the trajectory of the slide frame 7. When the snap ring 143 moves to be flush with the fixing strip 144, the snap ring 143 is moved again through the rotating rod 142, so that the snap ring 143 is engaged with the fixing strip 144, so that the hatch 8 is limited and fixed, and then the locking strip 18 is rotated to make the locking strip 18 close to the locking strip 18. When the limit of motor 2 is cancelled, the auxiliary handle 9 can be held to pull out the motor 2 and perform maintenance on the motor 2. After the maintenance of motor 2 is completed, the author puts the motor 2 back into the placement frame 5, and pushes the motor 2. When it is pushed to a certain position, the connecting block 152 contacts the boost propeller 3, and the spring 154 is squeezed and deformed, so that the auxiliary frame 153 moves backward along the trajectory of the main block 151, and the spring 154 rebounds at the same time. At this time, the boost propeller 3 is rotated manually. When the boost propeller 3 rotates to a certain extent, the rebound force of the spring 154 will move the connecting block 152 into the docking groove 11, so that the motor 2 is reconnected with the boost propeller 3, thereby having the advantages of assisting the heat dissipation of the motor 2 and facilitating maintenance.

[0038] To sum up: the water flow booster device for fire hydrants is provided with an intake fan 12, an exhaust fan 13 and a hatch 8. When the motor 2 needs regular maintenance, the hatch 8 is first opened, and then the motor 2 is taken out for maintenance, to avoid problems when the motor 2 drives the booster propeller 3 for a long time. At the same time, the intake fan 12 quickly inhales air, and the exhaust fan 13 quickly discharges the internal hot air, which solves the problem that the motor is sealed in the fire hydrant, and when the motor provides power to the booster device for a long time, there is no good heat dissipation, and it will overheat and cause power drop or mechanical failure. In addition, the motor needs regular maintenance to avoid problems in emergency situations, thereby affecting the rescue.
