[0002] A vertical fire pump is a type of fire-fighting equipment, mainly used for boosting water supply in fire protection systems. It can also be used for mine water supply and drainage. It features high reliability, meaning that it will not seize up when restarted after a long period of inactivity. It is also characterized by high efficiency, low noise, low vibration, and easy inspection.

[0003] Vertical fire pumps generate vibration during operation. To reduce the impact of vibration on the equipment and the surrounding environment, vibration damping pads are usually installed between the pump and the mounting foundation. However, after long-term use, existing vibration damping pads are prone to aging and damage due to the vibration of the pump, and need to be replaced in a timely manner.

[0004] However, the traditional method of replacing shock absorbers is quite complicated. It often requires disassembling the entire water pump, which is cumbersome and consumes a lot of time and manpower. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a three-dimensional adjustable modular frame structure for fire-fighting vertical water pumps, aiming to solve the problem that the traditional method of replacing shock-absorbing pads is relatively complicated, often requiring the entire water pump to be disassembled during replacement, which is cumbersome and consumes a lot of time and manpower.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional adjustable modular frame structure for a vertical fire pump, including a base. A stud assembly is fixedly connected to the upper side of the base. From bottom to top, the outer wall of the stud assembly is provided with a second nut, a second support plate, a third nut, a first support plate, a connecting plate, and a third nut. A pre-set gap is provided between the lower side of the second support plate and the upper side of the base. A cylindrical shock absorber is provided on the upper side of the second support plate.

The thickness of the cylindrical shock absorber is less than the gap of the stud assembly.

[0007] Preferably, the upper side of the support plate is provided with a groove three and a plurality of sloping grooves, and the plurality of sloping grooves are all connected to the upper part of the groove three.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a three-dimensional adjustable modular frame structure for a fire-fighting vertical water pump, including a base 7. A stud assembly 10 is fixedly connected to the upper side of the base 7. The outer wall of the stud assembly 10 is provided with a second nut 6, a second support plate 5, a third nut 11, a first support plate 4, a connecting plate 1, and a first nut 3 in sequence from bottom to top. There is a preset gap between the lower side of the second support plate 5 and the upper side of the base 7. A cylindrical shock absorber 9 is provided on the upper side of the second support plate 5. The upper side of the cylindrical shock absorber 9 is located on the lower side of the first support plate 4. A pump body 2 is fixedly connected to the upper side of the connecting plate 1. The thickness of the cylindrical shock absorber 9 is less than the gap of the stud assembly 10.

[0025] In this embodiment, Figure 1The orientation is indicated by front, back, left, and right. Specifically, nut 13 is equipped with an anti-loosening washer, stud assembly 10 has four studs, and the thickness of the cylindrical damping block 9 is less than the gap between two studs. The base 7 provides support for stud assembly 10. When installing the water pump, the lower side of support plate 25 is tightened and limited by the threaded connection between nut 26 and stud assembly 10. Then, the cylindrical damping block 9 is placed in the middle of the four studs, so that its lower side fits against the upper side of support plate 25. Next, nut 31 is threaded onto stud assembly 10, and support plate 14 is fitted onto stud assembly 10. The height of the four nuts 26 is adjusted, and... The support plate 4 is leveled using a leveling instrument. Then, the connecting plate 1, which is connected to the pump body 2, is fitted onto the stud assembly 10. The pump body 2 is installed by tightening the nut 3. During this process, the threaded connection between the nut 3 and the stud assembly 10 causes the support plate 4 and the support plate 5 to press the cylindrical damping block 9, and the upper side of the nut 11 and the lower side of the support plate 4 are not in contact. When the pump body 2 vibrates, the vibration is transmitted to the support plate 4 through the connecting plate 1, and then to the cylindrical damping block 9. The vibration is absorbed by the deformation of the cylindrical damping block 9, thereby achieving vibration reduction of the pump body 2.

[0026] When the cylindrical shock absorber 9 needs to be replaced, tighten the four nuts 11 upwards, so that the support plate 4 supports the connecting plate 1. Then, move the nut 6 downwards, so that the support plate 5 moves downwards. Rotate the old cylindrical shock absorber 9 at a certain angle and pull it out. Replace the new cylindrical shock absorber 9. By moving the nut 6 upwards, tighten the support plate 5 again. Then loosen the nut 11 until it is no longer in contact with the support plate 4. The replacement of the cylindrical shock absorber 9 is completed. This solves the problem that the traditional method of replacing shock absorbers is complicated and often requires disassembling the entire water pump, which is cumbersome and consumes a lot of time and manpower.

[0027] Reference Figure 2 The upper side of the support plate 14 is provided with a groove 3 17 and multiple sloping grooves 13. The multiple sloping grooves 13 are all connected to the upper part of the groove 3 17. Multiple liquid dampers 18 are provided on the inner wall of the groove 3 17. One end of the liquid damper 18 is fixedly connected to one side of the connecting plate 1. The connecting plate 1 is provided with a through hole. The outer wall of the stud assembly 10 passes through the through hole on the connecting plate 1, and there is a pre-set gap between the inner wall of the through hole on the connecting plate 1 and the outer wall of the stud assembly 10.

[0028] Specifically, the liquid damper 18 can be a liquid spring damper, which is existing technology. There are four liquid dampers 18, which are evenly distributed around the connecting plate 1. There is a certain distance between the through hole on the connecting plate 1 and the stud assembly 10, so that the connecting plate 1 and the stud assembly 10 can have a certain degree of displacement. When installing the connecting plate 1, the stud assembly 10 is passed through the through hole on the connecting plate 1, so that one end of the liquid damper 18 is aligned with the slope groove 13. The connecting plate 1 is pressed through the sloped inner wall of the slope groove 13, so that the liquid damper 18 slides into the groove 17. At this time, one end of the liquid damper 18 is in contact with the inner wall of the groove 17. Then, the connecting plate 1 is installed on the stud assembly 10 through the nut 3. When the pump body 2 is subjected to horizontal vibration, the vibration is converted into heat through the slight displacement of the connecting plate 1 and the support plate 4 and the absorption of vibration by the liquid damper 18, thereby realizing the horizontal vibration reduction of the pump body 2.

[0029] Reference Figure 1 and Figure 3 The upper side of the base 7 has a circular hole 8, the outer wall of the stud assembly 10 passes through the circular hole 8, and the circular hole 8 and the nut 6 are interference fit.

[0030] Specifically, when it is necessary to replace the cylindrical shock absorber 9, the nut 6 can be moved downward into the upper circular hole 8 of the base 7 by means of the interference fit between the circular hole 8 and the nut 6, which can reduce the installation height of the pump body 2 to a certain extent and improve the stability of the pump body 2 during operation.

[0031] Reference Figure 1 and Figure 4 The outer wall of the support plate 14 has multiple heat dissipation holes 12, which pass through the groove 3 17.

[0032] Specifically, the support plate 4 provides support for the heat dissipation hole 12. When the liquid damper 18 absorbs the horizontal vibration of the pump body 2 and converts it into heat, the heat is dissipated through the outer wall of the liquid damper 18 into the groove 17. The setting of the heat dissipation hole 12 can increase the air exchange speed between the inside and outside of the groove 17, carry away the heat, and thus help to improve the service life of the liquid damper 18.

[0033] Reference Figure 2 and Figure 4 The upper side of the cylindrical shock absorber 9 has a second circular hole 16, and the lower side of the support plate 4 is slidably connected to a guide rod 20, the lower end of which is slidably connected inside the second circular hole 16.

[0034] Specifically, when replacing the cylindrical shock absorber 9, the second round hole 16 on the upper side of the new cylindrical shock absorber 9 can be aligned with the guide rod 20 on the lower side of the support plate 4 to guide the cylindrical shock absorber 9. Then, by moving the second nut 6 upward, the support plate 5 can be tightened to complete the replacement of the cylindrical shock absorber 9. This avoids the movement of the cylindrical shock absorber 9 during replacement, which would reduce the shock absorption effect of the pump body 2.

[0035] Reference Figure 4 A spring 19 is installed inside the lower side of the support plate 4, and the lower end of the spring 19 is fixedly connected to the upper end of the guide rod 20.

[0036] Specifically, the spring 19 is supported by the support plate 4, and the guide rod 20 is slidably connected to the support plate 4, so that the guide rod 20 can be retracted into the support plate 4. When replacing the cylindrical shock absorber 9, the guide rod 20 will not interfere with the cylindrical shock absorber 9, and the installation height of the pump body 2 is also reduced, which helps to improve the efficiency of replacing the cylindrical shock absorber 9.

[0037] Reference Figure 2 The outer wall of the cylindrical shock absorber 9 is provided with a groove 14 that matches the nut 11, and there is a pre-set gap between the outer wall of the nut 11 and the inner wall of the groove 14.

[0038] Specifically, the groove 14 on the cylindrical damping block 9 allows the thickness of the cylindrical damping block 9 to be increased to a certain extent, thereby improving the damping performance of the cylindrical damping block 9. The preset distance between the nut 11 and the groove 14 ensures that the cylindrical damping block 9 does not interfere with the rotation of the nut 11, thus helping to improve the damping effect of the cylindrical damping block 9 on the pump body 2.

[0039] Reference Figure 2 The upper side of the support plate 2 5 is provided with a groove 2 15, and the outer wall of the cylindrical shock absorber 9 is slidably connected to the inner wall of the groove 2 15.

[0040] Specifically, the vertical sliding connection between the cylindrical damping block 9 and the groove 15 further limits the installation position of the cylindrical damping block 9, avoiding a decrease in damping performance after replacing the cylindrical damping block 9. When replacing the cylindrical damping block 9, the groove 15 reduces the height of the cylindrical damping block 9 rotating between the support plate 2 5 and the support plate 4, thereby helping to reduce the installation height of the pump body 2 and thus improving the stability of the water pump.

[0041] Working principle: When installing this water pump, the lower side of the support plate 2 5 is tightened and limited by the threaded connection between nut 2 6 and stud assembly 10. Then, the cylindrical shock absorber 9 is placed between the four studs, so that its lower side fits against the upper side of the support plate 2 5. Next, nut 3 11 is threaded onto the stud assembly 10, and support plate 1 4 is fitted onto the stud assembly 10. By adjusting the height of the four nuts 2 6 and using a leveling instrument to level the support plate 1 4, the stud assembly is secured. 10 passes through the through hole on the connecting plate 1, so that one end of the liquid damper 18 is aligned with the sloped groove 13. Through the sloped inner wall of the sloped groove 13, the connecting plate 1 is pressed, so that the liquid damper 18 slides into the groove 3 17. At this time, one end of the liquid damper 18 is in contact with the inner wall of the groove 3 17. Then, the connecting plate 1 is installed on the stud assembly 10 by the nut 13. Through the action of the cylindrical shock absorber 9 and the liquid damper 18, the shock absorption of the pump body 2 is achieved.

[0042] When the cylindrical shock absorber 9 needs to be replaced, tighten the four nuts 11 upwards, so that the support plate 4 supports the connecting plate 1. Then, move the nut 6 downwards, so that the support plate 5 slides downwards, and pull out the old cylindrical shock absorber 9 by rotating it at a certain angle. Replace it with the new cylindrical shock absorber 9. By moving the nut 6 upwards, tighten the support plate 5 again. Then loosen the nut 11 until it is no longer in contact with the support plate 4, thus completing the replacement of the cylindrical shock absorber 9. This solves the problem that the traditional method of replacing shock absorbers is complicated, often requiring the entire water pump to be disassembled, which is cumbersome and consumes a lot of time and manpower.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
