Description

Technical Field

[0001] This utility model relates to the technical field of vertical single-stage fire pumps, specifically a reliable vertical single-stage fire pump. Background Technology

[0002] Vertical single-stage fire pumps are typically designed as high-efficiency single-stage pumps, capable of providing high flow and high pressure water supply with low energy consumption. This ensures that the fire protection system can quickly provide sufficient water pressure and flow to cope with emergencies. Vertical single-stage fire pumps adopt a vertical structure and have a small external size, saving valuable installation space. They are suitable for the installation and use of various fire protection equipment. The design takes into account the ease of maintenance, allowing for easy disassembly, cleaning, and repair, reducing maintenance time and costs.

[0003] For example, the vertical single-stage fire pump disclosed in the authorization announcement number CN215411092U includes: a fire pump body, a mounting base fixedly connected to the bottom end of the fire pump body, a base provided at the lower end of the mounting base, an inner groove opened at the upper end of the base, an annular groove opened in the upper wall of the inner groove, sliders fixedly connected to the middle of both sides of the mounting base, the sliders being slidably connected in the annular groove of the inner groove, and a rotating mechanism provided on one side of the lower end of the mounting base and inside the inner groove;

[0004] While it enables convenient transportation of the fire pump body to the required installation location, the position of the casters can be fixed by the stabilizing mechanism to restrict the movement of the casters, making the fire pump body more stable when placed; by setting a rotating mechanism, the angle of the fire pump body can be adjusted by rotating the upper mounting base and the fire pump body.

[0005] However, this does not solve the problem that existing vertical single-stage fire pumps are generally not convenient for easy mobile pumping, not easy to independently control multiple outputs for drainage, not easy to easily and elastically scrape and clean impurities from the filter, and not easy to discharge in multiple directions, which greatly affects the convenience of connecting multiple pipes to the vertical single-stage fire pump. Utility Model Content

[0006] The purpose of this utility model is to provide a reliable vertical single-stage fire pump to solve the problems mentioned in the background art, such as the inconvenience of moving and pumping water, the inconvenience of independently controlling multiple outputs for drainage, the inconvenience of easily and elastically scraping and cleaning filtered impurities, and the inconvenience of discharging in multiple directions, which affect the convenience of connecting multiple pipes to the vertical single-stage fire pump.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reliable vertical single-stage fire pump, comprising a support plate and longitudinal supports. Longitudinal supports are provided on both sides of the support plate, and servo motors are installed at the top of each longitudinal support. Threaded rods are provided inside each longitudinal support, and the output ends of the servo motors are connected to the threaded rods. Threaded blocks are fitted onto the surface of each threaded rod, and the threaded blocks are connected to the support plate. An inlet pipe is movably installed at the center of the support plate, and a pump body is installed at the top of the inlet pipe. A cover is fitted onto the end of the inlet pipe away from the pump body, and a pin is movably installed on the surface of the cover, extending through the cover to the surface of the inlet pipe. A filter screen is installed at the bottom of the cover, and a support block is installed at the top of the pump body.

[0008] Preferably, a stepper motor is mounted on the top of the support block, and an extension shaft is mounted on the output end of the stepper motor.

[0009] Preferably, the extended shaft extends through the pump body to the bottom of the filter screen, and four sets of equally spaced water outlet pipes are installed on the inner wall of the pump body.

[0010] Preferably, a valve is installed at the end of the water outlet pipe away from the pump body, and an impeller is fitted onto the surface of the extended shaft inside the pump body.

[0011] Preferably, a bolt is movably installed at the center of the outer wall of the support plate, and the bolt extends into the interior of the support plate to contact the water inlet pipe.

[0012] Preferably, a connecting plate is installed at the bottom end of the extended shaft, and vertical plates are installed on both sides of the connecting plate.

[0013] Preferably, springs are symmetrically installed on the sidewalls of the vertical plates, and scrapers are installed on the side of the springs away from the vertical plates.

[0014] Preferably, each of the longitudinal supports is equipped with a base plate at its bottom end, and each base plate is equipped with two sets of wheels at its bottom end.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the vertical single-stage fire pump not only realizes the convenient walking and moving of the vertical single-stage fire pump for water pumping, and facilitates independent control of multiple outputs for drainage, but also facilitates the convenient elastic scraping and cleaning of filtered impurities, facilitates multi-directional discharge, and improves the convenience of connecting multiple pipes to the vertical single-stage fire pump.

[0016] (1) The longitudinal support is moved by the wheel, the servo motor drives the threaded rod to rotate, the threaded rod drives the threaded block to move downward, the threaded block drives the support plate, pump body, outlet pipe, inlet pipe and filter screen to move downward. When the inlet pipe enters the water, the stepper motor drives the extended shaft to rotate, the extended shaft drives the impeller to rotate, the impeller draws water by rotating, the water enters the pump body through the filter screen and inlet pipe, and is discharged to the external pipe through the outlet pipe under the action of the valve. When the water volume is too large and one set of valves cannot discharge in time, the other valves are opened to facilitate water pumping and discharge from multiple directions. Tighten the pin to fix the cover and filter screen on the surface of the inlet pipe. The water enters the pump body through the filter screen, and the impurities in the water will adhere to the surface of the filter screen. This realizes the convenient walking and moving of the vertical single-stage fire pump for water pumping, facilitates the arbitrary adjustment of the height to adapt to the water level for water pumping, facilitates independent control of multiple outputs for drainage, facilitates the filtration of the pumped water, and improves the practicality of the vertical single-stage fire pump.

[0017] (2) The connecting plate is driven to rotate by the extended shaft. The connecting plate drives the vertical plate, spring and scraper to rotate. Under the action of the spring, the scraper elastically scrapes the impurities on the surface of the filter screen, which avoids the impurities from entering the fire pump and causing blockage. It is convenient to clean the attached impurities, and realizes the convenient elastic scraping and cleaning of the filtered impurities by the vertical single-stage fire pump, which avoids the impurities from entering the vertical single-stage fire pump and causing blockage.

[0018] (3) When it is necessary to rotate the angle for drainage, unscrew the bolts and rotate the pump body and inlet pipe at a certain angle under the support of the support plate so that the outlet pipe and valve can discharge in different directions, which facilitates multi-directional drainage and realizes convenient multi-directional drainage of the vertical single-stage fire pump, and improves the convenience of connecting multiple pipes to the vertical single-stage fire pump.

[0028] Please see Figure 1-7 An embodiment of this utility model provides a reliable vertical single-stage fire pump, including a support plate 1 and a longitudinal support 2. The support plate 1 is provided with longitudinal supports 2 on both sides. The top of the longitudinal support 2 is equipped with a servo motor 5. The interior of the longitudinal support 2 is provided with a threaded rod 4. The output end of the servo motor 5 is connected to the threaded rod 4. The surface of the threaded rod 4 is fitted with a threaded block 3. The threaded block 3 is connected to the support plate 1. The water inlet pipe 7 is movably installed at the center of the support plate 1. The top of the water inlet pipe 7 is equipped with a pump body 8. The end of the water inlet pipe 7 away from the pump body 8 is fitted with a cover 15. The surface of the cover 15 is movably equipped with a pin 16, and the pin 16 passes through the cover 15 and extends to the surface of the water inlet pipe 7. The bottom of the cover 15 is equipped with a filter screen 17. The top of the pump body 8 is equipped with a support block 10.

[0029] A stepper motor 9 is mounted on the top of the support block 10, and an extension shaft 12 is mounted on the output end of the stepper motor 9;

[0030] The extended shaft 12 extends through the pump body 8 to the bottom of the filter screen 17, and four sets of water outlet pipes 13 with equal spacing are installed on the inner wall of the pump body 8.

[0031] A valve 14 is installed at the end of the water outlet pipe 13 away from the pump body 8, and an impeller 11 is fitted on the surface of the extended shaft 12 inside the pump body 8.

[0032] When using the fire pump, push the longitudinal support 2. Supported by the base plate 22, the wheels 23 drive the longitudinal support 2 to move. Turn on the servo motor 5. Supported by the longitudinal support 2, the servo motor 5 drives the threaded rod 4 to rotate. The threaded rod 4 drives the threaded block 3 to move downward. The threaded block 3 drives the support plate 1, pump body 8, outlet pipe 13, inlet pipe 7, and filter screen 17 to move downward. When the inlet pipe 7 enters the water, turn on the stepper motor 9. Supported by the support block 10, the stepper motor 9 drives the extension shaft 12 to rotate. The extension shaft 12 drives the impeller 11 to rotate. The impeller 11 draws water by rotating. The water passes through the filter screen 17 and the inlet pipe 7. Water enters the pump body 8 and is discharged to the external pipe through the outlet pipe 13 under the action of valve 14. When the water volume is too large and one set of valves 14 cannot discharge in time, the other valves 14 are opened to facilitate pumping water and discharge from multiple directions. Tighten the pin 16 to fix the cover 15 and filter screen 17 to the surface of the inlet pipe 7. Water enters the pump body 8 through the filter screen 17, and impurities in the water will adhere to the surface of the filter screen 17. This realizes the convenient walking and mobile pumping of the vertical single-stage fire pump, facilitates arbitrary height adjustment to adapt to the water level for pumping, facilitates independent control of multiple outputs for drainage, facilitates the filtration of pumped water, and improves the practicality of the vertical single-stage fire pump.

[0033] A connecting plate 18 is installed at the bottom of the extended shaft 12. Vertical plates 19 are installed on both sides of the connecting plate 18. Springs 20 are symmetrically installed on the side walls of the vertical plates 19. A scraper 21 is installed on the side of the springs 20 away from the vertical plates 19.

[0034] Each of the longitudinal supports 2 has a base plate 22 installed at its bottom end, and each base plate 22 has two sets of wheels 23 installed at its bottom end. The connecting plate 18 is driven to rotate by the extended shaft 12. The connecting plate 18 drives the vertical plate 19, spring 20, and scraper 21 to rotate. Under the action of the spring 20, the scraper 21 elastically scrapes the impurities on the surface of the filter screen 17, preventing the impurities from entering the fire pump and causing blockage. This facilitates the cleaning of the attached impurities and realizes that the vertical single-stage fire pump can conveniently and elastically scrape and clean the filtered impurities, preventing the impurities from entering the vertical single-stage fire pump and causing blockage.

[0035] A bolt 6 is movably installed at the center of the outer wall of the support plate 1, and the bolt 6 extends into the interior of the support plate 1 to contact the water inlet pipe 7;

[0036] When it is necessary to rotate the pump body 8 and the inlet pipe 7 to drain water, the bolt 6 is loosened and the pump body 8 and the inlet pipe 7 are rotated at a certain angle under the support of the support plate 1, so that the outlet pipe 13 and the valve 14 can be discharged in different directions. This facilitates multi-directional drainage and realizes convenient multi-directional drainage of the vertical single-stage fire pump, improving the convenience of connecting multiple pipes to the vertical single-stage fire pump.

[0037] Working Principle: When the fire pump is in use, the longitudinal support 2 is pushed, and the wheels 23 drive the longitudinal support 2 to move. The servo motor 5 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the threaded block 3 to move downward. The threaded block 3 drives the support plate 1, pump body 8, outlet pipe 13, inlet pipe 7, and filter screen 17 to move downward. When the inlet pipe 7 enters the water, the stepper motor 9 drives the extension shaft 12 to rotate, and the extension shaft 12 drives the impeller 11 to rotate. The impeller 11 draws water by rotating. The water enters the pump body 8 through the filter screen 17 and inlet pipe 7, and is discharged to the external pipeline through the outlet pipe 13 under the action of valve 14. When the water volume is too large and one set of valves 14 cannot discharge in time, the other valves 14 are opened. To facilitate multi-directional water discharge, tighten pin 16 to fix cover 15 and filter screen 17 to the surface of inlet pipe 7. Water enters pump body 8 through filter screen 17, and impurities in the water adhere to the surface of filter screen 17. The connecting plate 18 is driven to rotate by extension shaft 12. The connecting plate 18 drives vertical plate 19, spring 20, and scraper 21 to rotate. Under the action of spring 20, scraper 21 elastically scrapes the impurities on the surface of filter screen 17. Unscrew bolt 6, and under the support of support plate 1, rotate pump body 8 and inlet pipe 7 at a certain angle to allow outlet pipe 13 and valve 14 to discharge in different directions, facilitating multi-directional discharge and completing the operation of vertical single-stage fire pump.
