Description

Technical Field

[0001] The present application relates to fire protection pipelines, and in particular to a support device for a water pump connection in a pump room of a building fire protection system. Background Art

[0002] The water pipe network in the pump room of the building fire protection system is the core structure of the pump room, so durability and stability are particularly important.

[0003] See attached Figure 1 The water pipe network of the pump room includes a water pipeline 2 and a water pump 1. The water pump 1 is installed on the ground. The water pipeline 2 is suspended or supported by the pipe rack, and one end of the water pipeline 2 extends vertically downward and is connected to the water outlet of the water pump 1. Since the water pump 1 will generate vibration during operation, which will affect the stability of the water pump 1 and the water pipeline, a flexible joint is installed in the vertical section of the water pipeline. The flexible joint includes an upper flange 2111 at the upper end, a lower flange 2112 at the lower end, and a hose 212 and a shock-absorbing spring 213 located between the upper flange 2111 and the lower flange 2112. The deformation of the hose 212 and the shock-absorbing spring 213 can reduce vibration.

[0004] However, due to the insufficient supporting strength of the flexible joint in the vertical direction, it is easily damaged by the weight of the water pipe above and the flow of water. Therefore, a set of supporting structures is required to enhance the safety of the connection. The conventional supporting structure uses a vertical column 8 to directly weld the upper end to the side of the upper flange 2111, and the lower end of the steel pipe abuts the ground and is fixed to the ground, so as to support the water pipe and reduce the impact of water flow.

[0005] In actual application, it was found that after the support structure was fixed, due to pipeline leakage, the leaked liquid would flow down along the weight and come into contact with the welding points of the vertical steel pipe and the flexible joint flange. It was easily corroded by the leaked liquid and needed maintenance in the near future. However, its structure made it inconvenient to disassemble and the maintenance cost was high. Summary of the invention

[0006] In order to reduce the maintenance frequency and maintenance cost of a water pump connection support device, a water pump connection support device for a pump room of a building fire protection system is provided.

[0007] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0008] A support device for a water pump connection in a pump room of a building fire protection system comprises a support plate and a support rod, wherein the support plate supports an upper flange of a flexible pipe, the upper end of the support rod is detachably connected to the support plate and supports the support plate, and the lower end of the support rod is fixed to the ground.

[0009] By adopting the above technical solution, in this application, the support plate is supported by the support rod, and the support plate then supports the upper flange of the flexible pipe, so that the support plate directly contacts the upper flange of the flexible pipe. If the support plate is contaminated or corroded by leakage, it is only necessary to remove the support plate and replace it during maintenance. This ensures that the support device can provide effective support while making maintenance more convenient and reducing the required maintenance cost.

[0010] Optionally: There are at least two support plates and support rods, and they are evenly distributed around the upper flange axis of the flexible pipe.

[0011] By adopting the above technical solution, the supporting force of the supporting device on the upper flange of the flexible pipe is more evenly distributed and the support is more stable. At the same time, when the pipeline, such as a water pump, vibrates when starting and stopping, the support plate can undergo a slight misalignment change in the vertical direction, pressing down on the bent support rod, thereby reducing the vibration amplitude of the pipeline through deformation and improving the safety and stability of the pipeline.

[0012] Optionally, the adjacent side surfaces of the support plates are joined together, and the upper surfaces of the support plates are provided with raised anti-leakage edges.

[0013] The adjacent leak-proof edges are connected end to end, and the upper flange of the flexible pipe is located within the enclosure of the leak-proof edges.

[0014] By adopting the above technical scheme, sewage or leaked liquid flowing down from the pipeline from top to bottom will be blocked by the support plate and collected in the groove formed on the inner side of the leak-proof edge, and discharged by the inspection personnel during regular inspections, thereby further reducing the possibility of sewage and leaked liquid corroding the pipeline and support rod below after flowing out of the support plate, and improving the aesthetics of the pipeline and the bottom surface.

[0015] Optionally, there are two support plates and two support rods, and the two support plates are joined together and are in a circular shape.

[0016] By adopting the above technical solution, the supporting direction of the support plate to the end face flange is more uniform, and the supporting effect of the supporting device is more stable.

[0017] Optionally: a countersunk hole is formed on the support plate, the upper end of the countersunk hole is pressed against the bottom surface of the pipeline flange, and a fixing nut which is completely sunk into the countersunk hole is buried in the countersunk hole;

[0018] A fixing seat is fixed on the upper end of the support rod, a fixing bolt is passed through the lower part of the fixing seat, and the fixing bolt is threadedly connected with a fixing nut.

[0019] By adopting the above technical solution, the support plate and the support rod are fixed by bolt connection, which makes the preparation and replacement of parts more convenient and reduces the maintenance cost;

[0020] Furthermore, the fixing nut is completely located in the countersunk hole, and the upper end of the countersunk hole is in close contact with the bottom surface of the pipe flange, reducing the possibility of sewage and leakage from the bolt connection, ensuring the beauty of the pipeline and the ground while reducing the possibility of corrosion and damage to the fixing bolts and nuts.

[0021] Optionally: the end surfaces of the support plates are coated with a hydrophobic coating.

[0022] By adopting the above technical solution, the joints of the support plates have better anti-leakage properties, reducing the possibility of sewage and leaked liquid penetrating into the joints of the support plates and flowing out or corroding the support plates.

[0023] Optionally, the support rod is inclined from bottom to top toward the upper flange of the flexible pipe.

[0024] By adopting the above technical solution, when the upper flange of the flexible pipe vibrates in the horizontal direction, the support rod provides more restraining force to the upper flange of the flexible pipe in the horizontal direction through the supporting plate, and the supporting stability of the supporting device is better.

[0025] Optionally, the lower end of the support rod is fixed by embedding in concrete.

[0026] By adopting the above technical solution, the lower end of the support rod is fixed more stably

[0027] In summary, this application has at least the following beneficial effects:

[0028] 1. In this application, the support plate is supported by the support rod, and the upper flange of the flexible pipe is supported by the support plate. The support plate directly contacts the upper flange of the flexible pipe. If the support plate is contaminated or corroded by leakage, it only needs to be disassembled and replaced during maintenance. In this way, while ensuring the effective support of the support device, maintenance is more convenient and the required maintenance cost is reduced;

[0029] 2. The sewage or leaked liquid flowing down from the pipeline from top to bottom will be blocked by the support plate and collected in the groove formed on the inner side of the leak-proof edge, and discharged by the inspection personnel during regular inspections, further reducing the possibility of sewage and leaked liquid corroding the pipeline and support rod below after flowing out of the support plate, and improving the aesthetics of the pipeline and bottom surface;

[0030] 3. When the upper flange of the flexible pipe vibrates in the horizontal direction, the support rod provides more restraining force to the upper flange of the flexible pipe in the horizontal direction through the supporting plate, and the supporting stability of the supporting device is better.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings.

[0037] As attached Figure 2 As shown, a support device for the connection of a water pump 1 in a pump room of a building fire protection system is installed at the connection between the water pump 1 and the water delivery pipeline 2.

[0038] There is a mounting platform 3 cast with concrete on the ground, the water pump 1 is fixed on the mounting platform 3, and the water outlet of the water pump 1 is arranged horizontally.

[0039] The water delivery pipeline 2 is connected to the water outlet of the water pump 1, and a section of the pipeline connected to the water outlet is bent upward and then extended vertically.

[0040] As attached Figure 3 As shown, a flexible pipe 21 is also installed on the vertical water delivery pipeline 2, and the flexible pipe 21 includes connecting flanges 211 at both ends, a hose 212 located between the two connecting flanges 211, and a plurality of shock absorbing springs 213 located between the two connecting flanges 211. The two connecting flanges 211 are marked as an upper flange 2111 and a lower flange 2112 according to their positions.

[0041] The water flows through the flexible pipe 21 through the hose 212. When the water flow fluctuates, the hose 212 bends and deforms to adapt to the direction of the water flow fluctuation, and transmits the water flow vibration to the shock-absorbing spring 213 to reduce the vibration.

[0042] As attached Figure 2 and attached Figure 3 As shown, the supporting device for the water pump connection of the pump room of the building fire protection system of the present application includes a supporting plate 4 supporting the upper flange 2111 and a supporting rod 5 installed on the ground.

[0043] As attached Figure 3As shown, there are multiple supporting plates 4, which are against the lower bottom surface of the upper flange 2111 and are evenly distributed around the axis of the upper flange 2111. The number of supporting plates 4 can be determined according to the diameter of the pipeline and the required supporting weight. The larger the diameter and the larger the required supporting weight, the more supporting plates 4 are required. Here, two supporting plates 4 are used as an example.

[0044] The plurality of supporting plates 4 are mutually pressed and assembled into a circular ring coaxial with the upper flange 2111. The inner diameter of the circular ring is larger than the diameter of the inner hole of the upper flange 2111, and the outer diameter of the circular ring is larger than the outer diameter of the upper flange 2111.

[0045] The upper surface of the supporting plate 4 is provided with a raised anti-leakage edge 41 at the outer edge of the circular ring. The anti-leakage edges 41 on the supporting plate 4 are connected end to end to form an annular surrounding edge, surrounding the upper flange 2111 therein.

[0046] As attached Figure 4 As shown, the end surfaces of the support plate 4 that are in contact with each other are coated with a hydrophobic coating 43, and the coating thickness is less than 0.2 mm. The hydrophobic coating is applied and then cured. The hydrophobic coating used is an epoxy resin or other commercially available coating mixed with hydrophobic nano-modified white carbon black, so that the joints of the support plate 4 have better anti-leakage properties, reducing the possibility of sewage and leaked liquid penetrating into the joints of the support plate 4 and flowing out or corroding the support plate 4.

[0047] As attached Figure 2 As shown, the number of support rods 5 is the same as the number of support plates 4, and they are located one by one below the support plates 4. The lower end of the support rod 5 is fixed to the ground, and concrete embedding is adopted here, which is convenient for fixing and prevents the water pump 1 from being corroded by water infiltration in the room and the lower end of the support rod 5.

[0048] As attached Figure 2 and attached Figure 3 As shown, the support rod 5 is inclined from bottom to top, inwardly toward the axis of the upper flange 2111, and its upper end abuts against the ground of the supporting plate 4.

[0049] As attached Figure 4 As shown, fixing plates 51 are fixed on both sides of the upper end of the support rod 5 , and through holes 511 are vertically penetrated through the fixing plates 51 .

[0050] At the same time, a countersunk hole 42 is formed on the upper surface of the support plate 4 located above the fixing plate 51. Here, two support plates 4 are taken as an example, and two countersunk holes 42 are formed on both support plates 4. The upper end of the countersunk hole 42 passes through the upper surface of the support plate 4, and its cross section is a regular hexagonal deformation. The lower end of the countersunk hole 42 passes through the bottom surface of the support plate 4, and its cross section is a circle.

[0051] As attached Figure 3 and attached Figure 4As shown, when the supporting plate 4 is assembled and coaxially pressed against the lower end of the upper flange 2111, the upper end of the countersunk hole 42 abuts against the bottom surface of the upper flange 2111 and is completely covered by the bottom surface of the upper flange 2111, and the lower end of the countersunk hole 42 is aligned with a through hole 511.

[0052] The support rod 5 and the support plate 4 are fixed by bolts, which include a fixing nut 6 embedded in the countersunk hole 42 and a fixing bolt 7 passing through the through hole 511 from below. The fixing bolt 7 has a thread on the upper end, passes through the through hole 511 and the countersunk hole 42 in sequence, and is inserted into the fixing nut 6 and threadedly connected therewith, thereby fastening the support plate 4 and the upper end of the support rod 5.

[0053] The working principle of the present application: In the present application, the support plate 4 is supported by the support rod 5, and the support plate 4 then supports the upper flange 2111 of the flexible pipe 21, so that the support plate 4 directly contacts the upper flange 2111 of the flexible pipe 21. If the support plate 4 is contaminated or corroded by liquid leakage, it is only necessary to dismantle the support plate 4 and replace it during maintenance, thereby ensuring that the support device effectively supports, making maintenance more convenient, and reducing the required maintenance cost.

[0054] At the same time, sewage or leaked liquid flowing down from the pipeline from top to bottom will be blocked by the support plate 4 and collected in the groove formed on the inner side of the leak-proof edge 41, and discharged by the inspection personnel during regular inspections, further reducing the possibility of sewage and leaked liquid corroding the pipeline and support rod 5 below after flowing out of the support plate 4, and improving the aesthetics of the pipeline and the bottom surface.

[0055] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of protection required by the present invention, it will be protected by the patent law.
