Description

Technical Field

[0001] The present application relates to the field of fire pumps, and in particular to an automatic excess water discharge device for a fire pump. Background Art

[0002] Fire pumps, as the name suggests, are used in firefighting and are categorized into various types based on their fully sealed, leak-proof, and corrosion-resistant characteristics. They are widely used in environmental protection, water treatment, firefighting, and other sectors. They are ideal for pumping various liquids and creating leak-free, pollution-free, civilized workshops and factories, as well as firefighting systems. While all types of pumps are similar, differing only in head and flow rate, fire pump selection should be based on five key considerations: process flow, water supply and drainage requirements, and so on.

[0003] In the prior art, the residual water in a fire pump is usually drained by manually opening the drain ball valve at the bottom of the pump casing. Otherwise, the residual water in the pump will freeze and crack the pump casing. However, the freezing of residual water indicates that the weather is cold. At this time, the water pumped up by the pump may contain some crushed ice. The channel for draining the residual water from the pump body may be blocked by the crushed ice, which makes it inconvenient to reduce the possibility of blockage by crushing the crushed ice.

The elastic telescopic rod 605 specifically includes a sleeve rod and a movable rod. A spring is provided between the sleeve rod and the movable rod for resetting. At the same time, a rubber ring is provided between the sleeve rod and the movable rod to play a damping role. The elastic telescopic rod 605 can automatically elastically reset after compression, but will slowly reset under the damping action of the rubber ring. It is a prior art. The elastic telescopic rod 605 is fixedly connected to the right side of the drain pipe 403, and a crushing piece 7 is provided below the impeller group 4. The crushing piece 7 includes a vertical shaft 701, which is fixedly connected to the lower part of the impeller group 4. The lower end of the vertical shaft 701 is fixedly connected to the limited telescopic rod 702. The limited telescopic rod 702 specifically includes a sleeve rod and a movable rod.

A hydraulic component 8 is provided between the crushing member 7 and the blocking member 6. The hydraulic component 8 includes a first hydraulic pipe 801. Liquid is provided in the first hydraulic pipe 801. The first hydraulic pipe 801 passes through and is fixedly connected to the right side of the pump housing 1. One end of the first hydraulic pipe 801 extends from the bottom of the inner surface of the residual water discharge channel 3. The inner surface of the first hydraulic pipe 801 is slidably connected to the first piston rod 802 and the second piston rod 803. The second piston rod 803 is rotatably connected to the bottom of the crushing blade 703. The upper end of the first piston rod 802 is fixedly connected to a sliding ball 804. A return spring 805 is elastically connected between the sliding ball 804 and the first hydraulic pipe 801. The return spring 805 is used to reset the first piston rod 802. A heat dissipation component 9 for dissipating heat from the pump housing 1 is assembled on the right side of the pump housing 1. A circulation component 10 for reusing residual water is provided on the turntable above the water storage tank 404.

[0036] When the above device is used, water is first taken in through the water inlet 401, and then the water outlet 402 is pumped by the rotation of the impeller group 4. After the water enters the water inlet 401, it will fill the inner cavity 2 and pour into the residual water channel 3 and the drain pipe 403. At this time, the rotation of the impeller group 4 will drive the vertical shaft 701 to rotate, and the rotation of the vertical shaft 701 will drive the limiting telescopic rod 702 to rotate the crushing blade 703. The rotation of the crushing blade 703 will generate a vortex in the water, which will attract the crushed ice in the water downward and crush it. At this time, the rotation of the impeller group 4 will also drive the bevel gear group 406 to rotate The shaft 405 rotates, and the rotation of the rotating shaft 405 drives the chain condition 503 to rotate the rotating column 502, and the rotation of the rotating column 502 drives the top block 504 to rotate. At this time, the rotation of the top block 504 pushes the pressure bar 604 to make it fall. The falling pressure column 603 drives the elastic telescopic rod 605 to compress, and at the same time drives the pressure column 603 to fall to make the plug 602 insert into the plug seat 601, thereby blocking the drain pipe 403. At this time, the plug 602 will undergo a certain deformation to firmly plug the plug seat 601. Since the rotation speed of the impeller group 4 is fast enough, the elastic telescopic rod 605 will be compressed and will not have time to reset, and it will re-enter the plug seat 601. Once pushed and compressed, the elastic telescopic rod 605 will be in a small telescopic movement process. At this time, the plug head 602 will be slightly loosened, and the deformation of the plug head 602 will be slightly slowed down, but it will still firmly plug the plug seat 601. The small telescopic movement of the elastic telescopic rod 605 will make the pressure bar 604 shake up and down, and the pressure bar 604 will press the sliding ball 804 and the first piston rod 802. The first piston rod 802 will first be pressed down for a distance and then continue to rise and fall slightly under the action of the return spring 805 to reset. Therefore, the first piston rod 802 will continue to expand and contract in the first hydraulic pipe 801. This in turn pushes the liquid in the first hydraulic pipe 801, causing the second piston rod 803 to extend and retract up and down. The second piston rod 803 will drive the crushing blades 703 to vibrate up and down, thereby enhancing the crushing effect of the ice. When the impeller group 4 stops, the counterweight wheel 505 will be pulled down by gravity, and the rotating column 502 will be reset under the action of the counterweight wheel 505. At this time, the top block 504 on the rotating column 502 no longer presses against the pressure bar 604, and the elastic telescopic rod 605 is completely reset, so that the plug seat 601 is opened, so that the remaining water in the inner cavity 2 can be automatically leaked and transported to the water storage tank 404 for storage.

[0037] Example 2, see Figure 2-Figure 7, the heat dissipation component 9 includes a heat dissipation bin 901, the heat dissipation bin 901 is fixedly connected to the right side of the pump body shell 1, the heat dissipation bin 901 is communicated with the inner surface of the pump body shell 1, and is used to dissipate heat from the motor in the pump body shell 1, and a heat dissipation fan 902 is provided on the inner surface of the heat dissipation bin 901, and the heat dissipation fan 902 includes its frame and fan body, and the fan is driven to rotate by an external power supply, which is a prior art. The heat dissipation fan 902 is fixedly connected to the front and rear surfaces of the heat dissipation fan 902. The heat dissipation fan 902 is slightly tilted upward in a normal state, and the rotating stick 903 penetrates and is rotatably connected to the inner surface of the heat dissipation bin 901. A bearing is provided between the rotating stick 903 and the heat dissipation bin 901, and an air duct 904 is provided on the right side of the heat dissipation fan 902. A bell mouth is provided at one end of the air duct 904 facing the heat dissipation fan 902. 4 is fixedly connected to the top of the water tank 404, and the air guide pipe 904 is connected to the inner surface of the water tank 404. The air guide pipe 904 is used to guide the hot air into the water tank 404. The heat dissipation component 9 also includes a second hydraulic pipe 905. Liquid is provided in the second hydraulic pipe 905. The second hydraulic pipe 905 is fixedly connected to the rear of the first hydraulic pipe 801. The second hydraulic pipe 905 is L-shaped and is connected to the inner surface of the first hydraulic pipe 801.

The first gear 908 is fixedly connected to the outer surface of the rotating rod 903.

[0038] When the above-mentioned device is used, the cooling fan 902 is started to dissipate heat from the inside of the running pump housing 1. A portion of the dissipated heat will be introduced into the water tank 404 through the air duct 904, thereby increasing the temperature inside the water tank 404, thereby melting the broken ice in the remaining water in the water tank 404 and preventing the remaining water from freezing. When the first piston rod 802 pushes the liquid in the first hydraulic pipe 801, it also pushes the liquid in the second hydraulic pipe 905, thereby pushing the hydraulic rod 906 out of the second hydraulic pipe 905. The rising of the hydraulic rod 906 will drive the rack 907 to rise and turn the first gear 908 to rotate, so that the rotating rod 903 drives the cooling fan 902 to rotate, and the slightly upward cooling fan 902 will return to its normal position. At this time, the continuous expansion and contraction of the first piston rod 802 in the first hydraulic pipe 801 will drive the hydraulic rod 906 in the second hydraulic pipe 905 to continuously expand and contract, so that the rack 907 can reciprocate up and down in a small range, and then the first gear 908 can be turned to make the cooling fan 902 swing continuously, so as to improve the heat dissipation effect.
