Description

Technical Field

[0001] This utility model relates to the field of vertical pressure stabilizing pump technology, specifically a vertical pressure stabilizing pump with vibration reduction and noise reduction structure. Background Technology

[0002] Vertical pressure-stabilizing pumps are pressure-stabilizing devices used in automatic sprinkler systems and fire hydrant water supply systems. They ensure that the system water pressure remains at the required level, providing the necessary volume and pressure for firefighting once water is dispensed from the sprinkler heads or fire hydrants. During operation, vertical pressure-stabilizing pumps generate vibration and noise, which can affect the normal operation of the equipment and potentially disturb the surrounding environment and personnel.

[0003] According to Chinese Patent CN109185117B, a pressure-stabilizing pump with a vibration-damping and noise-reducing structure is disclosed. The pump is first assembled into a housing, which is then assembled onto the water purifier base. A vibration-damping device is added at the junction of the housing's support legs and the base to ensure a flexible connection between them. This device dampens and buffers the vibration, reducing the transmission of pump vibration and noise to the base, thus confining the pump's noise and vibration within the housing. This effectively controls and reduces the overall vibration and noise of the machine. This vibration-damping structure significantly reduces overall machine vibration and noise, greatly improving overall machine performance and user experience.

[0004] The aforementioned device uses vibration damping pads and buffer pads between the pressure-stabilizing pump housing and the base to reduce vibration and noise. However, over time, these pads may be affected by factors such as compression, fatigue, and aging, leading to a decline in their performance and loss of their original vibration damping and buffering capabilities, requiring frequent replacement. Therefore, we provide a vertical pressure-stabilizing pump with a vibration-damping and noise-reducing structure. Utility Model Content

[0005] The purpose of this invention is to provide a vertical pressure-stabilizing pump with a vibration-damping and noise-reducing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical pressure stabilizing pump with a vibration reduction and noise reduction structure, comprising: a vertical pressure stabilizing pump;

[0007] A base plate fixedly connected to the bottom of the vertical pressure stabilizing pump;

[0008] A mounting block that is fixedly connected to the front side of the base plate;

[0009] A mounting bolt with a thread that passes through the top of the mounting block;

[0010] The locating frame with threads passing through the bottom end of the mounting bolt;

[0011] A sound-absorbing cavity is formed on the inner surface of the positioning frame;

[0012] A sound-absorbing plate that snaps onto the inner surface of the sound-absorbing cavity;

[0013] A sound insulation board is fixedly connected to the top of the sound-absorbing panel;

[0014] An operating component is fixedly connected to the bottom of the positioning frame; the operating component is fixedly connected to the support part at the bottom of the positioning frame, and the support part is connected to a vibration damping part.

[0015] Preferably, the support includes a base that is snapped onto the outer wall of the bottom end of the positioning frame. The base has a movable groove on its inner side, and a slider is slidably connected to the inner surface of the movable groove. A fixed support block is fixedly connected to the outer side of the slider. A movable support block is provided below the fixed support block. An adjusting rod is hinged to the right side of the top of the movable support block. The end of the adjusting rod away from the movable support block is hinged to the inner surface of a U-shaped plate. A supporting elastic plate is fixedly connected to the top of the U-shaped plate. A guide rod is fixedly connected to the inner side of the base, and the two ends of the guide rod movably pass through both sides of the movable support block.

[0016] Preferably, the vibration damping part includes a movable rod fixedly connected to the side of the movable support block. The right end of the movable rod passes through the left side of the cylinder and is fixedly connected to a piston block. A buffer spring is fixedly connected to the left side of the cylinder, and the end of the buffer spring away from the cylinder is fixedly connected to one side of the movable support block.

[0017] Preferably, the bottom of the base plate and the top surface of the sound insulation board are configured to be in contact, which facilitates the installation and disassembly of the vertical pressure stabilizing pump and the replacement of the sound insulation board.

[0018] Preferably, the bottom of the positioning frame is fixedly connected to the top of the fixed support block, and the fixed support block supports the positioning frame.

[0019] Preferably, the bottom surface of the fixed support block and the top surface of the movable support block are both set as arc-shaped surfaces. The bottom surface of the fixed support block and the top surface of the movable support block are abutted together. When the fixed support block is vibrated, it squeezes the movable support block, causing the movable support block to move towards the middle position of the guide rod, thereby buffering the vibration.

[0020] Preferably, the top of the supporting elastic plate is fixedly connected to the bottom of the positioning frame, and the supporting elastic plate provides elastic support for the positioning frame.

[0023] Compared with the prior art, this utility model provides a vertical pressure stabilizing pump with a vibration reduction and noise reduction structure, which has the following beneficial effects:

[0024] This vertical pressure-stabilizing pump with vibration reduction and noise reduction structure generates vibrations during operation, which affect the positioning frame and cause the fixed support blocks on both sides to press down. The fixed support blocks on both sides squeeze the movable support blocks on both sides, causing them to move closer to the center under the force. As the movable support blocks on both sides move, they hinge the bottom ends of the adjusting rods on both sides closer together, causing the adjusting rods to drive the U-shaped plate to rise. The U-shaped plate then drives the supporting elastic plate to rise, thereby supporting the positioning frame and limiting the downward movement of the positioning frame, thus improving the stability of the positioning frame.

[0025] This vertical pressure-stabilizing pump with vibration reduction and noise reduction structure moves the movable support blocks on both sides towards the middle. The movable support blocks on both sides drive the piston blocks to move through the moving rods on both sides. The piston blocks on both sides move in opposite directions in the cylinder, causing the internal gas to be compressed in opposite directions. At the same time, with the elasticity of the buffer spring, the energy of the impact is absorbed, further improving the shock absorption and buffering effect. Attached Figure Description

[0034] Example 1: The vertical pressure-stabilizing pump with vibration reduction and noise reduction structure provided by this utility model, such as... Figures 1 to 5 As shown: A vertical pressure-stabilizing pump with a vibration reduction and noise reduction structure includes: a vertical pressure-stabilizing pump 1;

[0035] The base plate 2 is fixedly connected to the bottom of the vertical pressure stabilizing pump 1;

[0036] Mounting block 3 is fixedly connected to the front of the base plate 2;

[0037] The threaded mounting bolt 4 passes through the top of the mounting block 3;

[0038] The thread passes through the positioning frame 5 at the bottom of the mounting bolt 4;

[0039] A sound-absorbing cavity 6 is formed on the inner surface of the positioning frame 5;

[0040] The sound-absorbing plate 7 is snapped onto the inner surface of the sound-absorbing cavity 6;

[0041] The sound insulation board 8 is fixedly connected to the top of the sound-absorbing board 7;

[0042] An operating component 9 is fixedly connected to the bottom of the positioning frame 5; the operating component 9 is fixedly connected to the support 91 at the bottom of the positioning frame 5, and the support 91 is connected to the vibration damping part 92.

[0043] The support part 91 includes a base 918 that is snapped onto the outer wall of the bottom end of the positioning frame 5. A movable groove 911 is provided on the inner side of the base 918. A slider 912 is slidably connected to the inner surface of the movable groove 911. A fixed support block 913 is fixedly connected to the outer side of the slider 912. A movable support block 914 is provided below the fixed support block 913. An adjusting rod 915 is hinged to the right side of the top of the movable support block 914. The end of the adjusting rod 915 away from the movable support block 914 is hinged to the inner surface of the U-shaped plate 916. A supporting elastic plate 917 is fixedly connected to the top of the U-shaped plate 916. A guide rod 919 is fixedly connected to the inner side of the base 918. The two ends of the guide rod 919 movably pass through both sides of the movable support block 914.

[0044] In this embodiment, the bottom of the base plate 2 and the top surface of the sound insulation plate 8 are set to contact each other, which facilitates the installation and disassembly of the vertical pressure stabilizing pump 1 and the replacement of the sound insulation plate 8.

[0045] Furthermore, the bottom of the positioning frame 5 is fixedly connected to the top of the fixed support block 913, and the fixed support block 913 supports the positioning frame 5.

[0046] Furthermore, the bottom surface of the fixed support block 913 and the top surface of the movable support block 914 are both set as arc-shaped surfaces. The bottom surface of the fixed support block 913 and the top surface of the movable support block 914 are abutted together. When the fixed support block 913 is vibrated, it squeezes the movable support block 914, causing the movable support block 914 to move towards the middle position of the guide rod 919 under force, thereby buffering the vibration.

[0047] Preferably, the top of the support elastic plate 917 is fixedly connected to the bottom of the positioning frame 5, and the support elastic plate 917 provides elastic support for the positioning frame 5.

[0048] Example 2: Based on Example 1, the vertical pressure-stabilizing pump with vibration reduction and noise reduction structure provided by this utility model, such as... Figures 1 to 5 As shown: The vibration damping part 92 includes a movable rod 921 fixedly connected to the side of the movable support block 914. The right end of the movable rod 921 passes through the left side of the cylinder 922 and is fixedly connected to a piston block 923. A buffer spring 924 is fixedly connected to the left side of the cylinder 922. The end of the buffer spring 924 away from the cylinder 922 is fixedly connected to one side of the movable support block 914.

[0049] In this embodiment, the right end of the moving rod 921 extends through the left side of the cylinder 922, making it convenient for the moving rod 921 to move along with the movable support block 914.

[0050] Furthermore, the number of piston blocks 923 is set to two. The two piston blocks 923 are symmetrically slidably connected to both sides of the inner surface of the cylinder 922. By moving the two piston blocks 923 in opposite directions within the cylinder 922, the internal gas is compressed in opposite directions, thereby absorbing the energy of the impact.

[0051] In actual operation, when this device is in use, the vibration generated by the vertical pressure stabilizing pump 1 will affect the positioning frame 5, causing the fixed support blocks 913 on both sides to press down. The fixed support blocks 913 on both sides will squeeze the movable support blocks 914 on both sides, causing the movable support blocks 914 to move towards the middle under the force. As the movable support blocks 914 on both sides move, they will hinge the bottom ends of the adjusting rods 915 on both sides, causing the adjusting rods 915 to drive the U-shaped plate 916 to rise. The U-shaped plate 916 will drive the supporting elastic plate 917 to rise, thereby providing reverse support for the positioning frame 5 and limiting the downward movement of the positioning frame 5, thus improving the stability of the positioning frame 5. At the same time, when the movable support blocks 914 on both sides move towards the middle, the movable support blocks 914 on both sides will drive the piston block 923 to move through the moving rods 921 on both sides. The piston blocks 923 on both sides will move in opposite directions in the cylinder 922, causing the internal gas to be compressed in opposite directions. With the elasticity of the buffer spring 924, the impact energy will be absorbed, further improving the shock absorption and buffering effect.

[0052] Meanwhile, the sound-absorbing plate 7 and the sound-insulating plate 8, which are snapped together inside the positioning frame 5, work together to reduce the noise generated by the vertical pressure stabilizing pump 1 during operation.
