Description

Technical Field

[0001] This utility model belongs to the technical field of fire-fighting water supply equipment, and more specifically, it relates to a fire-fighting pressurized and stabilized water supply equipment with filtration function. Background Technology

[0002] With the rapid development of urban construction, the importance of building fire protection engineering is becoming increasingly prominent. In fire protection systems, water supply equipment is a crucial link in ensuring the smooth operation of fire fighting and rescue work. However, current water supply equipment on the market still faces certain technical bottlenecks in terms of pressure boosting and stabilization, especially in high-rise buildings and complex building environments, where the performance of existing equipment often fails to meet actual needs. Therefore, developing a high-efficiency, stable, and intelligent pressure boosting and stabilizing water supply system for building fire protection engineering is particularly important.

[0003] Some current fire-fighting booster and pressure-stabilizing water supply equipment with filtration functions only adds a filter screen at the water inlet pipe for filtration. However, impurities in the water can easily clog the filter screen, preventing water from passing through effectively and thus affecting the water supply effect of the equipment.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a fire-fighting booster and pressure-stabilizing water supply equipment with filtration function. The aim is to develop a building fire-fighting booster and pressure-stabilizing water supply equipment with high stability, low energy consumption and easy maintenance. We focus on optimizing the hardware structure design to solve the problems of slow pressure regulation, energy waste and short component life of traditional equipment. This will ensure that the pressure of the fire-fighting pipeline network is constant and controllable throughout the entire fire cycle, improve fire-fighting efficiency and system reliability, and promote the upgrading of fire-fighting water supply equipment towards modularization, lightweighting and intelligence. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fire-fighting booster and pressure-stabilizing water supply device with filtration function, which is achieved by the following specific technical means: A fire-fighting booster and pressure-stabilizing water supply device with filtration function includes a support platform, centrifugal pumps, and a pressure-stabilizing tank. The pressure-stabilizing tank is installed on one side of the upper end face of the support platform. The bottom of the pressure-stabilizing tank is connected to a drain pipe via a connecting pipe. The bottom end face of the drain pipe is connected to a pair of check valves via a pair of connecting pipes. A pair of centrifugal pumps are installed on the other side of the upper end face of the support platform. The outlets of the pair of centrifugal pumps are connected to the pair of check valves via connecting pipes. The inlets of the pair of centrifugal pumps are connected to a control valve via a connecting pipe. The control valve is connected to an inlet pipe via a connecting pipe. One end of the inlet pipe is connected to a filter. The filter includes a first mounting pipe, a second mounting pipe, a first filter cylinder, and a second filter cylinder. The first mounting pipe is fixedly connected to one side of the first filter cylinder, and the second mounting pipe is fixedly connected to one side of the second filter cylinder. An mounting block is installed on the inner wall of the first filter cylinder, and a filter screen is bolted to the mounting block. A cleaning mechanism is installed inside the first filter cylinder near the filter screen. A drain outlet is provided at the bottom of the first filter cylinder. The first filter cylinder is connected to the second filter cylinder via a flange.

[0006] Furthermore, the cleaning mechanism includes a first rotating shaft, a driving bevel gear, a second rotating shaft, a driven bevel gear, a scraper, and a motor. A support block is installed on the upper end face of the first filter cylinder, and a motor is installed on the upper end face of the support block. The output end of the motor is connected to the top end of the first rotating shaft, and a driving bevel gear is installed at the bottom end of the first rotating shaft. The driving bevel gear and the driven bevel gear mesh with each other. One side of the driven bevel gear is connected to one end of the second rotating shaft, and the other end of the second rotating shaft is connected to the scraper. The scraper is in contact with the surface of the filter screen.

[0007] Furthermore, a support rod is installed on one inner wall of the second filter cartridge, and a sealing box is installed at one end of the support rod. The driving bevel gear and the driven bevel gear are located inside the sealing box.

[0008] Furthermore, a support ring is installed around the second rotating shaft, and a second support rod is installed on the upper end face of the support ring. The top end of the second support rod is connected to the top of the first filter cylinder.

[0009] Furthermore, both the drain pipe and the second filter cylinder are equipped with on / off valves.

[0010] Furthermore, a pressure sensor is installed on the upper end face of the drain pipe.

[0011] Furthermore, one end of the drain pipe is connected to a pressure relief valve, the other side of the pressure relief valve is connected to a water supply pipe, and several branch pipes are installed on one side of the water supply pipe. The water supply pipe and the branch pipes are all made of galvanized pipe.

[0012] Furthermore, a control box is installed on the upper surface of the support platform near the pressure stabilizing tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Through the coordinated use of a motor, shaft one, driving bevel gear, shaft two, driven bevel gear, scraper, filter screen, and switch valve, water passes through the filter. The filter screen filters out impurities in the water. The motor drives the driving bevel gear to rotate via shaft one. The driving bevel gear rotates via the driven bevel gear. The driven bevel gear drives the scraper to rotate via shaft two. The scraper cleans the impurities on the surface of the filter screen by rotating. When a large amount of impurities accumulates on one side of the filter screen, the operator closes the switch valve in the second filter cylinder and then opens the switch valve in the drain pipe to quickly discharge the impurities. This process is simple to operate, thereby reducing downtime and avoiding affecting water delivery efficiency. Attached Figure Description
