Description

Technical Field

[0001] This utility model relates to the field of fire water supply system technology, and in particular to an adaptive variable pressure fire water supply pressure stabilizing and energy-saving device. Background Technology

[0002] In high-rise buildings, it can intelligently adjust water pressure according to floor height to ensure effective water supply for fire protection facilities on each floor; in densely populated places such as commercial complexes, it can dynamically respond to fluctuations in water load, taking into account both fire extinguishing efficiency and energy-saving requirements; in large-space scenarios such as industrial plants, it can accurately adapt to the pressure transformation requirements of special fire protection equipment, reducing equipment wear and tear.

[0003] A search revealed Chinese Patent Publication No. CN222752473U, which discloses a fire-fighting water supply pressure stabilizing device, relating to the field of fire-fighting water supply pressure stabilizing technology. The device includes an adjusting mechanism with a main body mechanism and a reinforcing mechanism. The adjusting mechanism includes a base plate with a support groove inside. An oil storage pad is fixedly connected inside the base plate, and a connecting rod is also fixedly connected inside. This invention uses a drive motor to rotate a threaded rod, thereby adjusting the position of two sets of threaded connecting plates. When the threaded connecting plates move, they cause a limiting rod to move within the support groove, thus improving the stability of the threaded connecting plates during movement. When the threaded connecting plates move, the rotating rod is subjected to force and rotates accordingly, coming into contact with the oil storage pad, resulting in lubricating oil on the surface of the rotating rod. This improves the smoothness of the threaded connecting plate movement, thereby increasing the flexibility of device installation and making device maintenance more convenient.

[0004] Although the aforementioned patent makes device maintenance more convenient through the cooperation of screw and threaded plate, it cannot adaptively adjust the pressure in different areas and buffer pressure fluctuations. Therefore, an adaptive variable pressure fire water supply pressure stabilizing and energy-saving device is proposed to solve the above problems. Utility Model Content

[0005] This utility model proposes an adaptive variable pressure fire water supply stabilizing and energy-saving device, which aims to improve the problem that some existing variable pressure fire water supply stabilizing and energy-saving devices cannot achieve adaptive adjustment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adaptive variable pressure fire water supply pressure stabilizing and energy-saving device includes a base plate, a pressure stabilizing tank fixedly connected to the outside of the base plate, a connecting flange fixedly connected to the outside of the pressure stabilizing tank, a connecting pipe fixedly connected to the outside of the connecting flange, an adjusting mechanism fixedly connected to the outside of the connecting pipe, and a buffer mechanism fixedly connected to the outside of the base plate. The regulating mechanism includes a voltage regulator, which is fixedly connected to the outside of the connecting pipe. A pressure sensor is fixedly connected to the outside of the connecting pipe. A water pump is fixedly connected to the outside of the base plate. A flange interface is fixedly connected to the outside of the water pump. A connecting pipe is fixedly connected to the drive end of the water pump. A pressure sensor is fixedly connected to the outside of the connecting pipe. A drive assembly is fixedly connected to the outside of the base plate.

[0007] The above solution involves a stable installation on a base plate, with the pressure tank connected to the connecting pipe via a connecting flange. A regulating mechanism enables precise pressure control, a pressure sensor monitors water pressure in real time, a transformer controller intelligently regulates the pump unit, and the water pump efficiently delivers water through the flange interface and connecting pipe. A buffer mechanism reduces vibration losses, thus improving overall water supply stability, energy efficiency, and reliability.

[0008] As a further description of the above technical solution: The buffer mechanism includes a fixed plate, which is externally fixedly connected to the outside of the base plate. The fixed plate is externally threaded with a fixing bolt, and the fixing bolt is externally fixedly connected with a connecting plate. The connecting plate is externally fixedly connected with a support block.

[0009] The above solution provides a solid foundation for installation by securing the base plate with a fixed plate, and the fixing bolts work in conjunction with the connecting plate to ensure that the equipment is installed horizontally. The support block enhances the structural strength and works with other components to effectively absorb vibrations during equipment operation and reduce vibration transmission.

[0010] As a further description of the above technical solution: The drive assembly includes a support plate, which is fixedly connected to the outside of the base plate, and a spare pump is fixedly connected to the outside of the support plate.

[0011] The above solution achieves redundancy between the standby pump and the main pump. When the water supply pump fails, it can be quickly activated to take over, ensuring uninterrupted fire water supply, significantly improving the reliability and emergency response capability of the fire protection system, and effectively avoiding the risk of water supply interruption due to equipment failure.

[0012] As a further description of the above technical solution: The support block is externally fixedly connected to a base, and the base is externally fixedly connected to a connecting block.

[0013] The above solution provides a stable support structure for the buffer mechanism by fixing the support block to the base, thus dispersing the pressure generated during equipment operation. The base can be connected to the ground or wall embedded parts through the connecting block, further enhancing the overall rigidity of the buffer mechanism, reducing vibration transmission, and ensuring that the equipment remains stable during operation.

[0014] As a further description of the above technical solution: The connecting plate is fixedly connected to the outside of a fixing rod, and the fixing rod is slidably connected to the outside of a follower rod.

[0015] The above solution involves a sliding connection between the follower rod and the fixed rod. When the equipment vibrates, the follower rod can slide flexibly along the fixed rod. The relative motion between the two effectively captures and buffers the kinetic energy generated by the vibration, creating conditions for the subsequent tension spring to absorb the vibration energy, thereby significantly reducing the impact of equipment vibration on the surrounding structure.

[0016] As a further description of the above technical solution: A tension spring is sleeved on the outside of the follower rod, and the tension spring is fixedly connected to the outside of the support block.

[0017] The above solution works as follows: when the equipment vibrates, the sliding rod drives the spring to compress or stretch. The spring converts the vibration energy into elastic potential energy through elastic deformation, thereby absorbing and buffering the vibration energy, effectively reducing the vibration intensity. In conjunction with other buffer components, it reduces the impact of equipment vibration on the base plate and surrounding structure, ensuring the stable operation of the device.

[0018] As a further description of the above technical solution: The connecting pipe is fixedly connected to the outside of the water supply pump, and the drive end of the standby pump is fixedly connected to the outside of the connecting pipe.

[0019] The above solution allows the backup pump to quickly take over the water supply through the connecting pipe when the water supply pump fails, ensuring uninterrupted fire-fighting water supply. At the same time, it optimizes the water flow path, reduces energy loss, and improves the reliability and operating efficiency of the water supply system.

[0020] As a further description of the above technical solution: One end of the tension spring is fixedly connected to the outside of the connecting plate, and the other end of the tension spring is fixedly connected to the outside of the support block.

[0021] The above solution allows the device to undergo compression or stretching deformation as it moves with the moving rod when vibration occurs during operation. Through elastic deformation, it effectively absorbs and converts vibration energy, transforming kinetic energy into elastic potential energy. This buffers the vibration impact, reduces the impact of equipment vibration on the base plate and surrounding structures, and enhances the stability and reliability of the device operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the water pressure in the pipeline network is monitored in real time by a pressure sensor, and the operating status of the main pump and the standby pump is intelligently adjusted by an adaptive variable pressure controller, so that the water supply pressure dynamically adapts to the needs of the scenario. The pressure stabilizing tank buffers pressure fluctuations and suppresses water hammer effect. The redundant design of the main pump and the standby pump in parallel ensures continuous water supply when a single pump fails, improves fire protection reliability, and accurately adjusts the pressure for different areas to ensure high-pressure fire extinguishing efficiency during a fire. The pressure stabilizing tank is connected to the pipeline network to buffer pressure fluctuations.

[0023] 2. In this utility model, the fixed plate drives the connecting plate to move, which in turn drives the fixed rod to move the follower rod, which in turn drives the tension spring to move the support block. This effectively absorbs the pressure shock caused by the start-up and shutdown of the water pump or fluctuations in water usage, preventing pipe rupture and valve damage due to sudden pressure changes in the pipeline network, reducing frequent start-up and shutdown of the water pump, reducing mechanical wear and energy consumption, and ensuring a continuous and safe water pressure supply.

Detailed Implementation

[0026] The following combination Figures 1-4 This application will be described in further detail below.

[0027] Example: An adaptive variable-pressure fire-fighting water supply pressure stabilizing and energy-saving device, referring to... Figure 1 , Figure 2 , Figure 4The system includes a base plate 1, which serves as the foundation. The surface of the base plate 1 is treated with an anti-rust coating, and bolt holes are pre-drilled at the four corners for secure installation on a flat surface using expansion bolts. A pressure stabilizing tank 2 is externally fixed to the base plate 1. The pressure stabilizing tank 2 has arc-shaped end caps at both ends to enhance its pressure-bearing capacity. A transparent observation window is provided on the side wall of the tank for easy real-time monitoring of the internal water level. A connecting flange 3 is externally fixed to the pressure stabilizing tank 2, and a connecting pipe 4 is externally fixed to the connecting flange 3. The inner wall of the connecting pipe 4 is smooth to effectively reduce water flow resistance. Reinforcing ribs are added at the connection points to further enhance the structural strength and stability. An adjustment mechanism 5 is externally fixed to the connecting pipe 4, and a buffer mechanism 7 is externally fixed to the base plate 1. The regulating mechanism 5 includes a transformer controller 51, which is a rectangular box shape with a waterproof operation panel on its surface. It integrates a display screen and control buttons, allowing for intuitive display of operating parameters and manual adjustment. The controller is connected to external components via a waterproof cable to receive and process pressure signals in real time. The transformer controller 51 is externally fixed to the outside of the connecting pipe 4, and a pressure sensor 52 is also externally fixed to the outside of the connecting pipe 4. The pressure sensor 52 has its probe inserted deep into the pipe, enabling it to accurately capture changes in water pressure and provide data support for system regulation. A water supply pump 54 is externally fixed to the base plate 1. The surface of the water supply pump 54 is densely packed. The water supply pump 54 is externally fixedly connected to a flange interface 53. The drive end of the water supply pump 54 is fixedly connected to a connecting pipe 55. The connecting pipe 55 is equipped with guide vanes inside to optimize the water flow direction and reduce eddy current loss. The connecting pipe 55 is externally fixedly connected to a pressure sensor 56, which monitors the water pump outlet pressure in real time and provides key data for system pressure regulation. The base plate 1 is externally fixedly connected to a drive assembly 6, which includes a support plate 61. The support plate 61 is externally fixedly connected to the outside of the base plate 1. The support plate 61 is externally fixedly connected to a spare pump 62. Specifically, when the adaptive variable pressure fire water supply pressure stabilizing and energy-saving device is started, pressure sensor 52 monitors the water pressure in the connecting pipe 4 in real time and transmits the data to the rectangular box-shaped variable pressure controller 51. After analysis and processing, the controller sends a command to the water supply pump 54. The heat dissipation fins on the surface of the water supply pump 54 assist in heat dissipation during operation. The water in the pressure stabilizing tank 2 is pressurized and transported to the pipeline system through the connecting pipe 55 connected to the flange interface 53. The guide vanes in the connecting pipe 55 optimize the water flow and reduce losses. At the same time, pressure sensor 56 monitors the water pump outlet pressure and feeds it back to the controller.

[0028] Reference Figure 1 , Figure 2 , Figure 3The buffer mechanism 7 includes a fixed plate 71, which is externally fixed to the outside of the base plate 1. The fixed plate 71 is rectangular with regularly distributed countersunk holes at its four corners. It is vertically fixed to the outside of the base plate 1 by welding. The fixed plate 71 is externally threaded with fixing bolts 72. By adjusting the fixing bolts 72, the tightness of the nuts between the connecting plates 73 can be adjusted, allowing for precise fine-tuning of the height of the buffer assembly and ensuring the horizontality of the equipment installation. The fixing bolts 72 are externally fixed to a connecting plate 73, which is a rectangular metal plate with multiple sets of elliptical through holes running horizontally through its surface. This allows for fine-tuning of the position of the fixing bolts 72. It can also allow a certain degree of elastic deformation during vibration. The connecting plate 73 is externally fixedly connected to a support block 74, and the support block 74 is externally fixedly connected to a base 75. The base 75 is a disc-shaped structure with a rubber pad attached to the bottom and a surface covered with anti-slip ripples. The rubber pad is bonded to the base 75 with high-strength industrial adhesive, which can effectively isolate vibration transmission and prevent the equipment from shifting during operation. The base 75 is externally fixedly connected to a connecting block 76, which is a rectangular block structure with a waist-shaped hole on the side. It can be connected to the embedded parts of the ground or wall through expansion bolts, further enhancing the overall rigidity of the buffer mechanism 7. A fixed rod 77 is fixedly connected to the outside of the connecting plate 73. A follower rod 78 is slidably connected to the outside of the fixed rod 77. A tension spring 79 is sleeved on the outside of the follower rod 78. The tension spring 79 is fixedly connected to the outside of the support block 74. The outside of the connecting pipe 55 is fixedly connected to the outside of the water supply pump 54. The drive end of the standby pump 62 is fixedly connected to the outside of the connecting pipe 55. One end of the tension spring 79 is fixedly connected to the outside of the connecting plate 73, and the other end of the tension spring 79 is fixedly connected to the outside of the support block 74. When the water supply pump 54 and the standby pump 62 start running, the vibration generated is transmitted to the buffer mechanism 7 along the connecting pipe 55. Under the action of vibration, the follower rod 78 moves in a reciprocating linear motion along the fixed rod 77, periodically compressing or stretching the tension spring 79. The tension spring 79 absorbs the vibration energy through elastic deformation, converts it into elastic potential energy and gradually dissipates it. At the same time, with the damping effect of the rubber pad of the base 75, it effectively suppresses the transmission of vibration to the base plate 1 and the surrounding structure. Specifically, when the water supply pump 54 and the standby pump 62 start running, the vibration generated by the pump body is transmitted to the buffer mechanism 7 through the connecting pipe 55. The rectangular fixed plate 71 is fixedly placed on the base plate 1, and the two rows of internal threaded holes on it are screwed into the fixing bolts 72. The transverse through hole of the connecting plate 73 is adapted to the bolts for fine adjustment. It can elastically deform during vibration. The support block 74 supports the base 75. The rubber pad at the bottom of the disc-shaped base 75 contacts the ground. The follower rod 78 slides back and forth along the cylindrical fixed rod 77. The tension spring 79 is periodically compressed or stretched. The two ends of the spring are fixed to the connecting plate 73 and the support block 74 respectively. It absorbs vibration energy and converts it into elastic potential energy through elastic deformation. The rubber pad of the base 75 plays a damping role at the same time to dissipate vibration and reduce the impact of equipment vibration on the base plate 1 and the surrounding structure.

[0029] The implementation principle of this application embodiment is as follows: When the fire water supply demand is triggered, the adaptive pressure controller 51 receives real-time water pressure data from the pressure sensor 52 at the key node of the pipeline network. After analysis by the intelligent algorithm, it sends a start command to the water supply pump 54. The water supply pump 54 is connected to the connecting pipe 55 through the flange interface 53 to transport the fire water in the pressure stabilizing tank 2 to the pipeline network system. During operation, the pressure sensor 56 continuously monitors the water pump outlet pressure and feeds it back to the pressure controller 51 to dynamically adjust the pump group operating power. When the pipeline network pressure fluctuates, the pressure stabilizing tank 2 achieves pressure buffering through the connecting flange 3 and the connecting pipe 4. When the water supply pump 54 fails, the backup pump 62 of the drive assembly 6 is quickly switched to start through the support plate 61 to maintain the continuity of water supply. When the water supply pump 54 and the standby pump 62 are started, the vibration generated by the pump body is transmitted to the buffer mechanism 7 through the connecting pipe 55. The rectangular fixed plate 71 is firmly fixed on the base plate 1, providing support for the buffer mechanism 7. The fixing bolts 72 on it cooperate with the rectangular connecting plate 73. When the vibration is transmitted, the follower rod 78 starts to reciprocate linearly on the fixed rod 77, compressing or stretching the tension spring 79 sleeved on it. The two ends of the tension spring 79 are fixed on the connecting plate 73 and the support block 74 respectively. Through elastic deformation, it absorbs the vibration energy and converts it into elastic potential energy, gradually dissipating the vibration energy, thereby reducing the impact of vibration on the base plate 1 and the surrounding structure.
