Description

Technical Field

[0001] This utility model relates to the field of fire pump technology, specifically a horizontal constant pressure tangential fire pump with convenient adjustment of the liquid outlet. Background Technology

[0002] The horizontal constant pressure tangential fire pump is a type of pump specifically designed for fire protection systems. Its main features include constant pressure output and tangential design. This type of pump can efficiently deliver water while maintaining constant water pressure, ensuring that the water output and pressure of fire protection equipment always meet the requirements. Its "constant pressure" characteristic ensures that the water pressure remains stable when the fire protection system is turned on, while the "tangential" design refers to the water flow entering in a tangential manner. This design can improve the pump's efficiency, reduce water flow resistance, and achieve more efficient delivery. Traditional fire pumps are mostly fixed in their outlets, which makes it inconvenient to flexibly adjust the outlet direction and the water output. To improve this situation, a horizontal constant pressure tangential fire pump with an easily adjustable outlet is proposed.

[0003] A horizontal fire pump disclosed in authorization announcement number CN220016344U includes a base, an mounting seat fixedly connected to the upper surface of the base, a motor fixedly connected to the upper surface of the mounting seat, a flange installed at one end of the motor, a pump body installed on one side of the flange, a support seat fixedly connected to the arc surface of the pump body, the support seat being fixedly connected to the base, an outlet pipe fixedly connected to one side of the pump body, an inlet pipe fixedly connected to the arc surface of the pump body, an adjustment structure provided at one end of the outlet pipe, the adjustment structure including a welding plate, the welding plate being fixedly connected to the outlet pipe, and a lead screw rotatably connected to one side of the welding plate;

[0004] Although it solves the problem that the high water pressure in the pump body can exert an impact force on the pipeline, which can easily lead to unstable connection between the outlet and the pipeline, causing fire water leakage and thus preventing timely firefighting in the event of a fire;

[0005] However, this does not solve the problem that existing fire pumps are not easy to rotate and adjust the water outlet direction during use, nor are they good at offsetting and adjusting the vibration generated during the use of fire pumps to adapt to different water output sizes, which affects the stability and flexibility of water use. Utility Model Content

[0006] The purpose of this utility model is to provide a horizontal constant pressure tangential fire pump with convenient outlet adjustment, so as to solve the problems mentioned in the background art, such as the fire pump not being convenient to rotate and adjust the water outlet direction, which is not conducive to the cancellation and adjustment of vibration generated during the use of the fire pump to adapt to different water volume, thus affecting the stability and flexibility of water use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a horizontal constant pressure tangential fire pump with convenient outlet adjustment, comprising a shock-absorbing box and a mounting base. The mounting base is provided above the shock-absorbing box, and multiple sets of equally spaced shock absorbers are installed at the bottom of the mounting base, with the bottom ends of the shock absorbers connected to the shock-absorbing box. A motor is installed at the top of the mounting base, and a fire pump body is installed at the top of the mounting base on one side of the motor, with the output end of the motor connected to the fire pump body.

A drive motor is installed at the top of the fire pump body on one side of the water outlet pipe, and a drive shaft is installed at the output end of the drive motor, with gears fitted on the surface of the drive shaft. A connecting pipe is installed at the top of the adapter sleeve, and an adjusting pipe is installed at the end of the connecting pipe away from the adapter sleeve. An electric push rod is installed on the side wall of the connecting pipe.

[0008] Preferably, a gear plate is installed on the outer wall of the adapter sleeve, and the gear plate meshes with the gear.

[0009] Preferably, the output end of the electric push rod is equipped with a push arm, and a slip ring is slidably installed on the outer wall of the adjusting tube, with the push arm and the slip ring being movably connected.

[0010] Preferably, a central block is installed at the center of the inside of the regulating tube, and multiple sets of blades at equal intervals are movably installed on the side wall of the central block.

[0011] Preferably, the surface of the slip ring is provided with multiple sets of short connecting arms at equal intervals, and each short connecting arm is provided with a hinge shaft at one end near the slip ring, and the short connecting arms are movably connected to the slip ring through the hinge shaft.

[0014] Preferably, the rotating shaft extends into the interior of the regulating tube and is movably connected to the regulating tube, and the rotating shaft is connected to the blade.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the fire pump not only realizes the convenient circumferential rotation to adjust the water outlet direction, which facilitates the compensation and adjustment of the vibration generated during the use of the fire pump to adapt to different water outlet sizes, but also improves the stability and flexibility of water use.

[0016] (1) The fire pump body is driven by a motor to pump water from the water storage tank through the outlet pipe and the adapter sleeve to the inside of the connecting pipe and discharged from the regulating pipe. When it is necessary to adjust the outlet direction of the connecting pipe, the drive motor drives the gear to rotate through the drive shaft, the gear drives the adapter sleeve and the connecting pipe to rotate through the gear plate, and the connecting pipe drives the regulating pipe to rotate, thereby adjusting the outlet position of the regulating pipe. When the device is in use, it will generate vibration. The vibration is transmitted to the shock absorber through the mounting seat, and the shock absorber cancels the vibration, thereby improving the stability of the fire pump during use. The shock absorber is the shock absorber commonly used on the back seat of electric bicycles in daily life. It realizes convenient circumferential rotation to adjust the outlet direction, which facilitates the cancellation of vibration generated during the use of the fire pump and improves the stability of use.

[0017] (2) The push arm is moved by the electric push rod, and the push arm drives the slip ring to slide on the outer wall of the regulating pipe. The slip ring drives the short connecting arm to rotate through the hinge shaft. The short connecting arm drives the long connecting arm to rotate through the linkage shaft.
