Description

Technical Field

[0001] This utility model relates to the technical field of booster pump coupling equipment, specifically a booster pump coupling. Background Technology

[0002] Booster pump connections are critical firefighting equipment, specifically designed for fire rescue. In the event of a sudden fire, if the fire pumps in a building fail or the water supply is insufficient, the fire truck pump can quickly connect to the building's internal fire piping system through the interface of the booster pump connection. This boosts the pressure of the water being transported and precisely delivers it to fire hydrants, automatic sprinkler systems, and other fire-fighting facilities. It not only supplements the water supply for firefighting but also significantly increases the fire water supply pressure, building a solid defense line for extinguishing fires and ensuring the smooth progress of rescue work.

[0003] For example, a booster pump connector disclosed in Chinese patent literature (publication number: CN222400096U) uses an adjusting component to regulate the water flow pressure, a limiting component to limit the adjusting component, and a detection component to detect the water inside the pump connector body.

[0004] However, this method requires multiple steps, such as manually pulling the limit post, separating the positioning block, and rotating the wheel, which is cumbersome and requires repeated adjustments to the limit structure. It relies on manual step-by-step operation, and opening and closing the valve takes a long time, which cannot meet the rapid response needs of emergency scenarios such as fire fighting.

The shaft end is fixedly connected to the top of the rotating shaft, and the shaft end is rotatably connected to the protective box, with the shaft end portion penetrating the protective box. The pointer is fixedly connected to the outer wall of the portion of the shaft end penetrating the protective box.

[0008] As a further embodiment of this utility model: the filtering mechanism includes a fixed ring, a sealing washer, and a movable ring. The fixed ring is fixedly connected to one end of the inner wall of the connection port. A sealing washer is movably inserted inside the sealing washer. The movable ring is fixedly connected to the back of the sealing washer. A screw and a filter bag are also included. The screw is located at one end of the back of the movable ring. The other end of the screw passes through the movable ring and the sealing washer and is threadedly connected to the fixed ring. The filter bag is fixedly connected to the inner ring of the movable ring.

[0009] As a further improvement of this utility model: the port of the connector is threadedly connected to an end cap, and the bottom of the connector body is fixedly connected to a connecting flange.

[0010] As a further improvement of this utility model: both the connection port and the filter mechanism are provided in two sets, and the two sets of connection ports are symmetrically arranged on both sides of the connector body.

[0011] As a further improvement of this utility model, the number of screws is provided in multiple groups, which are symmetrically arranged on the back of the movable ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the connector body is connected to an external water source via a connection port. A motor drives a rotating shaft through gear transmission, which in turn drives a ball valve to control water pressure. As the shaft rotates, a pointer at its end rotates synchronously and points to a crescent-shaped mark in a circular groove, visually displaying the ball valve opening and facilitating water pressure adjustment. This automated drive eliminates the need for manual operation, reducing labor intensity and enabling rapid valve opening and closing, meeting the urgent needs of fire-fighting and other emergency scenarios. The pointer and mark are linked, allowing for intuitive display of the ball valve opening without additional instruments, simplifying the operation process. Precise angle control is achieved through the connection of the motor and gears, and the motor has a built-in brake function to lock the position, eliminating the need for additional limiters. A filter bag is installed to intercept impurities in the water, preventing clogging or damage to internal components, and a sealing gasket ensures a tight seal to prevent leakage. The filter bag features a quick-release design, allowing for easy removal and cleaning by simply unscrewing the screws. Attached Figure Description

[0024] A valve stem 4 is fixedly connected to the top of the ball valve 3, connecting the ball valve 3 and the drive component, and playing the role of power transmission. A protective box 5 is fixedly connected to the top of the connector body 1. The protective box 5 is equipped with a drive pointing mechanism 6. The protective box 5 protects the internal drive pointing mechanism 6 from dust and damage.

[0025] A filter mechanism 7 is provided on one end of the inner wall of the connection port 2 for filtering external water sources. A circular groove 8 is opened on the top of the protective box 5. A crescent-shaped mark 9 is provided inside the circular groove 8, which, together with the pointing component, forms a visual scale to show the valve opening and closing status.

[0026] The number of connection ports 2 and the number of filter mechanisms 7 are both provided in two sets, and the two sets of connection ports 2 are symmetrically arranged on both sides of the connector body 1.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The driving pointing mechanism 6 includes a motor 61, a gear 62 and a rotating shaft 63. The motor 61 is fixedly connected to one end inside the protective box 5, the gear 62 is fixedly connected to the output end of the motor 61, and the rotating shaft 63 is fixedly connected to the top of the valve stem 4.

[0028] Gear 2 64, shaft end 65, and pointer 66 are included. Gear 2 64 is fixedly connected to the upper end of the outer wall of the rotating shaft 63 and meshes with gear 1 62. Shaft end 65 is fixedly connected to the top of the rotating shaft 63 and rotatably connected to the protective box 5, with part of shaft end 65 penetrating the protective box 5. Pointer 66 is fixedly connected to the outer wall of the part of shaft end 65 that penetrates the protective box 5. The motor 61 drives gear 1 62 to rotate, and gear 1 62 meshes with gear 2 64, driving the rotating shaft 63 to rotate. The rotating shaft 63 is fixedly connected to the valve stem 4. The ball valve 3 is driven to rotate within the connector body 1, thereby controlling the water pressure. When the rotating shaft 63 rotates, the shaft end 65 rotates accordingly, and the pointer 66 on its outer wall rotates synchronously with the rotating shaft. The pointer 66 points to the crescent-shaped mark 9 in the circular groove 8, which can intuitively display the rotation status of the ball valve 3, thereby regulating the water pressure. This method eliminates the need for manual operation, reduces labor intensity, and is suitable for emergency scenarios. The automated drive can complete the opening and closing of the valve in a short time, meeting the emergency needs of fire fighting and other scenarios.

[0029] Reference Figure 2 and Figure 6The filter mechanism 7 includes a fixed ring 71, a sealing gasket 72 and a movable ring 73.

[0031] Multiple sets of screws 74 are symmetrically arranged on the back of the movable ring 73. When water enters from the connection port 2, it first passes through the filter bag 75. Its mesh structure can intercept impurities such as mud, sand and rust in the water, preventing impurities from entering the connector body 1 and the pipe network, thus preventing blockage or damage to internal components. The sealing gasket 72 is used to ensure the sealing between the fixed ring 71 and the movable ring 73 to prevent water leakage. When it is necessary to clean the filter bag 75, the movable ring 73 and the filter bag 75 can be removed by unscrewing the screws 74, which is convenient for regular cleaning or replacement.

The bottom of the connector body 1 is fixedly connected to a connecting flange 11, which is used to connect to fire protection pipe networks or other equipment.

[0033] The working principle of this utility model is as follows: In use, the connector body 1 is connected to an external water source through the connection port 2. The motor 61 drives the gear 62 to rotate, and the gear 62 meshes with the gear 64, driving the rotating shaft 63 to rotate. The rotating shaft 63 is fixedly connected to the valve stem 4, thereby driving the ball valve 3 to rotate within the connector body 1, thus controlling the water pressure. When the rotating shaft 63 rotates, the shaft end 65 rotates accordingly, and the pointer 66 on its outer wall rotates synchronously with the rotating shaft. The pointer 66 points to the crescent-shaped mark 9 in the circular groove 8, which can intuitively display the rotation status of the ball valve 3, thereby adjusting the water pressure. This method eliminates the need for manual operation, reduces labor intensity, and is suitable for emergency scenarios. The automated drive can complete the valve opening and closing in a short time, meeting the emergency needs of fire fighting and other scenarios. The pointer 66 and the crescent-shaped mark 9... The linkage allows for intuitive display of the ball valve opening, eliminating the need for additional instruments and simplifying the operation process. Precise angle control is achieved through the connection of motor 61, gear 62, and gear 64 with shaft 63 and valve stem 4, eliminating the need for additional limit switches. Motor 61 has a built-in brake function to lock the position. When water enters from connection port 2, it first passes through filter bag 75. Its mesh structure intercepts impurities such as mud, rust, etc., preventing them from entering the connector body 1 and pipe network, thus preventing blockage or damage to internal components. Sealing gasket 72 ensures a tight seal between the fixed ring 71 and the movable ring 73, preventing leakage. When cleaning filter bag 75 is required, screw 74 is unscrewed to remove the movable ring 73 and filter bag 75 for regular cleaning or replacement. This quick-release design allows cleaning the filter without disassembling the main body, making it more convenient and practical.
