Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and more specifically to an anti-clogging water pump connector. Background Technology

[0002] Fire pump connections are fire protection facilities provided for high-rise buildings according to the "Code for Fire Protection Design of Buildings." They are typically connected to the water supply system of automatic sprinkler systems or fire hydrants within the building. In the event of a fire, the fire truck's pump can quickly connect to the building's fire protection equipment through the connection interface and pressurize the water, ensuring sufficient pressurized water for the indoor fire protection equipment. A fire pump connection usually consists of an interface, body, check valve, safety valve, shut-off valve, and connecting pipe. The shut-off valve is manually operated with a rotary wheel. In actual use, the shut-off valve's main function is to open and close the fire pump connection. However, due to insufficient signage, shut-off valves are often closed when they should be open, and this is not noticed in time, preventing immediate use when needed. Furthermore, during maintenance and repair of fire pump connections, the shut-off valves should be closed. However, due to the large number of fire pump connections in large buildings, each shut-off valve needs to be manually closed during maintenance and repair, resulting in a heavy workload for fire protection maintenance personnel, significantly impacting maintenance efficiency, and being time-consuming and labor-intensive. In response to this, the inventors have proposed an anti-clogging water pump connector. A rotating motor is installed on the top of the shut-off valve, which enables rapid opening and closing of the shut-off valve. The valve is also marked with its opening and closing status. Furthermore, the connector reduces the workload of maintenance personnel and improves maintenance efficiency.

[0003] To facilitate the maintenance and repair of fire pump connections and extend their service life, Chinese Patent (Authorization Announcement No.: CN222018858U) discloses a ground-mounted protective fire pump connection. This utility model includes a pump connection body, with a push-pull movable protective box covering the outside of the body for protection. Inside the protective box, a collision protection frame surrounds the outside of the pump connection body to provide impact protection. This utility model achieves the effects of protecting the pump connection, extending its service life, and facilitating use and subsequent maintenance and repair.

[0004] There are still some deficiencies in the application of this solution. Since fire-fighting facilities and equipment need to be in a state of combat readiness under normal conditions, in case of a fire, they can respond quickly, quickly activate the equipment for the use of firefighters. Otherwise, it is very easy to have equipment failures that delay the fire. At the same time, all fire-fighting equipment needs to be restored to its original state in case of an emergency for firefighters to operate manually. Therefore, it is necessary to improve the structure of the fire pump adapter so that it can prevent blockage and can also be disassembled in an emergency for easy manual operation, avoiding affecting fire extinguishing and effectively improving the practical performance. Summary of the Invention

[0005] The present invention discloses a blockage-proof fire pump adapter, and its main purpose is to overcome the above-mentioned deficiencies and disadvantages existing in the prior art:

[0006] The technical solution adopted by the present invention is as follows:

[0007] A blockage-proof fire pump adapter includes a fire pump adapter. The fire pump adapter includes an interface, a body, a connecting pipe, a check valve, a safety valve, and a stop valve. The stop valve includes a bottom cover and a hand wheel. The hand wheel is provided with an "X"-shaped support rod, and an arc-shaped perforation is formed between the support rods. On both sides of the bottom cover, there are "C"-shaped elastic steel strips. An electric motor is clamped between the top ends of the elastic steel strips. The driving end of the electric motor faces downward and a turntable is installed at the end. Four arc-shaped convex blocks are provided at the end of the turntable, and the arc-shaped convex blocks are adaptively embedded in the arc-shaped perforation. A red identification circle is provided around the upper part of the arc-shaped convex blocks.

[0008] Furthermore, fixed blocks are provided on both sides of the electric motor, and a circular hole is provided in the middle of the fixed blocks. The ends of the elastic steel strips are movably embedded in the circular holes.

[0009] Furthermore, a screw rod is provided between the hand wheel and the bottom cover, and a valve body is provided at the end of the screw rod.

[0010] Furthermore, the height of the arc-shaped convex blocks is less than the length of the screw rod.

[0011] Furthermore, the electric motor can be disassembled by bending the elastic steel strips outwards.

[0012] Furthermore, the electric motor drives the arc-shaped convex blocks to rotate, which带动 the hand wheel to rotate. The hand wheel rotates and moves up and down along the arc-shaped convex blocks to control the opening and closing of the stop valve.

[0013] From the above description of the present invention, it can be seen that compared with the prior art, the advantages of the present invention are:

[0014] In the present utility model, a motor is firstly added to the top of the globe valve, and an arc-shaped convex block is arranged at the end of the motor and embedded in the hand wheel of the globe valve. The motor can drive the hand wheel to rotate, so as to realize the quick opening and closing of the globe valve. Compared with the existing operation of manually operating the hand wheel, it can facilitate the maintenance personnel to save the trouble of manual rotation during maintenance and repair, achieving the effect of saving time and effort, especially in some buildings with a large number of fire pump adapters. Then, when the globe valve is in the open state, the hand wheel is within the red identification circle above the arc-shaped convex block, and when the globe valve is in the closed state, the hand wheel is below the red identification circle, with the state being clear at a glance, which can prevent the globe valve from being in the closed state and not being discovered in time, causing blockage. Finally, when the motor fails, only need to break out the end of the elastic steel bar from the circular hole of the fixed block to quickly remove the motor for manual operation, and it can be quickly restored to the original state in an emergency. The structure of the present utility model is novel and ingeniously designed, which can effectively prevent blockage and is convenient for maintenance and repair, and is suitable for popularization.

[0019] The following further describes the specific embodiments of the present utility model by referring to the description of the drawings.

[0020] As Figures 1 to 4 shown, a fire pump adapter for preventing blockage includes a fire pump adapter 1, and the fire pump adapter 1 includes an interface 2, a body 3, a connecting pipe 4, a check valve 5, a safety valve 6 and a globe valve 7. The globe valve 7 includes a bottom cover 71 and a hand wheel 72. The hand wheel 72 is provided with an "X"-shaped support rod 73, and an arc-shaped through hole 74 is formed between the support rods 73. Both sides of the bottom cover 71 are provided with a "C"-shaped elastic steel bar 8, and a motor 9 is clamped between the top ends of the elastic steel bars 8. The driving end of the motor 9 faces downward and a turntable 10 is installed at the end. Four arc-shaped convex blocks 11 are arranged at the end of the turntable 10, and the arc-shaped convex blocks 11 are adaptively embedded in the arc-shaped through hole 74, and a red identification circle 12 is annularly arranged above the arc-shaped convex blocks 11. <Furthermore, the motor 9 is provided with fixing blocks 13 on both sides, and the fixing blocks 13 are provided with circular holes 14 in the middle, and the end of the elastic steel strip 8 is movably embedded into the circular holes 14.

[0022] Furthermore, a lead screw 15 is provided between the handwheel 72 and the bottom cover 71, and a valve body is provided at the end of the lead screw 15 (not shown in the schematic diagram due to perspective).

[0023] Furthermore, the height of the arc-shaped protrusion 11 is less than the length of the lead screw 15.

[0024] Furthermore, the motor 9 can be disassembled by bending the elastic steel bar 8 outward.

[0025] Furthermore, the motor 9 drives the arc-shaped protrusion 11 to rotate, which in turn drives the handwheel 72 to rotate. The handwheel 72 rotates and moves up and down along the arc-shaped protrusion 11, controlling the opening and closing of the shut-off valve 7.

[0026] [Example]

[0027] First, bend the elastic steel strip 8 outwards on both sides, place the motor 9 in the middle, and fix the motor 9 by inserting the end of the elastic steel strip 8 into the circular hole 14 of the fixing block 13. At this time, the arc-shaped protrusion 11 at the end of the motor 9 is inserted into the arc-shaped through hole 74 on the handwheel 72, and the handwheel 72 is in the red marking circle 12 on the upper part of the arc-shaped protrusion 11. Firefighters and property personnel can know in time that the shut-off valve 7 is in the open state. Then, when maintenance and repair are required, start the motor 9, which drives the arc-shaped protrusion 11 to rotate. The arc-shaped protrusion 11 is locked in the arc-shaped through hole 74 and drives the handwheel. Rotating the handwheel 72 quickly closes the shut-off valve 7, eliminating the need for manual operation and facilitating maintenance. At this time, the handwheel 72 is located below the red indicator circle 12, allowing firefighters and property management personnel to promptly recognize that the shut-off valve 7 is in the closed state. Finally, in the event of a motor 9 malfunction or an emergency requiring manual operation of the handwheel to open or close the shut-off valve 7, simply pry the end of the elastic steel strip 8 outward to disassemble the motor 9 and the arc-shaped protrusion 11, restoring the handwheel 72 of the shut-off valve 7 to its original structure, facilitating manual operation by firefighters and on-site personnel.

[0028] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0029] This invention firstly adds a motor to the top of the shut-off valve, with an arc-shaped protrusion at the end of the motor embedded in the valve's handwheel. The motor drives the handwheel to rotate, enabling rapid opening and closing of the shut-off valve. Compared to existing manual operation of the handwheel, this design simplifies maintenance and repair, saving time and effort, especially in buildings with numerous fire pump connections. Secondly, when the shut-off valve is open, the handwheel is positioned within the red marking circle above the arc-shaped protrusion; when closed, it is positioned below the red marking circle, providing clear visibility and preventing the valve from going unnoticed and causing blockage. Finally, if the motor malfunctions, it can be quickly removed for manual operation by prying the end of the elastic steel strip out of the circular hole in the fixing block, allowing for rapid restoration in emergencies. This invention features a novel structure and ingenious design, effectively preventing blockage and facilitating maintenance, making it suitable for widespread adoption.

[0030] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
