Description

Technical Field

[0001] This utility model application relates to the field of water supply equipment technology, specifically a fire-fighting dual-power complete water supply system. Background Technology

[0002] Firefighting water supply equipment is an automatic fire extinguishing system consisting of a main fire pump, a standby fire pump, a pressure stabilizing pump set, a pressure tank, a pressure sensor, and a control cabinet. Normally, the pressure stabilizing pump set keeps the pipeline pressure stable at a set value. In case of fire, the main fire pump automatically starts to extinguish the fire. If the main fire pump fails, the standby fire pump automatically starts to operate. It is equipped with a dual power supply switching device, which can automatically switch to the standby power supply when the main power fails.

[0003] To ensure water supply, some consumer water supply equipment uses dual pumps to draw water, in addition to having a backup pump, to guarantee fire-fighting water supply. Currently, most pumps are fixed with several bolts during installation, which makes the operation of fixing the pumps cumbersome and laborious, thus making the assembly of water supply equipment more complicated. Summary of the Invention

[0004] To address the problem of cumbersome and laborious assembly of existing dual-power fire-fighting water supply systems, this utility model provides a dual-power fire-fighting water supply system to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire-fighting dual-power water supply system includes a fixed base. A main pump, a standby pump, and a second main pump are sequentially arranged on the top surface of the fixed base. Mounting blocks are fixed to the bottom surfaces of the main pump, standby pump, and second main pump. Each mounting block has a one-way opening limiting groove. A limiting block is slidably fitted inside each limiting groove, and the bottom surface of each limiting block is fixed to the top surface of the fixed base. A fixing rod is fixed to the mounting blocks on both sides of each limiting groove, and a fixing plate is rotatably fitted onto each fixing rod. A support block is symmetrically fixed to one end of each limiting block extending to the outside of the mounting block. Two fixing plates in each group engage inside the support block.

[0007] Furthermore, the input end of the standby pump is fixedly connected to an inlet 1, and an inlet 2 is fixedly connected to one side of the inlet 1. Both the inlet 2 and the inlet 1 above the inlet 2 are equipped with one-way valves.

[0008] Furthermore, the limiting groove is configured as an inverted "convex" shape that cooperates with the limiting block, and a shock-absorbing pad that cooperates with the outer surface of the limiting block is glued and fixed on the inner wall of the limiting groove.

[0009] Furthermore, the limiting block has symmetrical movable slots inside, and each movable slot is slidably fitted with a limiting rod. One end of each limiting rod that extends to the outside of the limiting block is inserted into the fixed plate. Each limiting rod inside the movable slot is threaded with a spring, and both ends of the spring are fixed to the movable slot and the limiting rod, respectively.

[0010] Furthermore, each of the fixing rods is configured as a horizontally placed "T" shape, and each of the fixing plates has a limiting insertion hole inside that cooperates with the limiting insertion rod.

[0011] Furthermore, each of the limiting rods and movable slots is configured as a horizontally placed "T" shape, and the end of the limiting rod that extends to the outside of the fixed plate abuts against the support block.

[0012] Furthermore, each of the support blocks is configured as an "L" shape to cooperate with the fixing plate, and each of the fixing plates has a rotating hole on its outer side to cooperate with the fixing rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, through the limiting snap-fit ​​design, during assembly, the installation block is fitted onto the limiting block and fixed by the fixing plate and the limiting rod, making the pump body easier and less labor-intensive to install. This solves the problem of the cumbersome and laborious assembly of existing fire-fighting dual-power complete water supply equipment, and greatly improves the convenience of water supply equipment installation.

[0015] 2. In this utility model, the vibration transmission of the pump body is reduced by the shock-absorbing rubber pad inside the limiting groove. At the same time, the easy disassembly design makes it easier to operate during maintenance and replacement. The backup water source of the backup pump can supply water in time when the original water source is unavailable, further ensuring the timeliness of water supply to the water supply equipment, thereby improving the stability of the water supply equipment during use.

Detailed Implementation

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 and Figure 3 A dual-power fire-fighting water supply system includes a fixed base 1. A main pump 2, a standby pump 3, and a second main pump 4 are sequentially arranged on the top surface of the fixed base 1. An inlet 5 is fixedly connected to the input end of the standby pump 3, and an inlet 6 is fixedly connected to the side of the inlet 5. One-way valves 7 are installed on both the second inlet 6 and the inlet 5 above it. Mounting blocks 8 are fixed to the bottom surfaces of the main pump 2, standby pump 3, and second main pump 4. Each mounting block 8 has a one-way opening limiting groove 9 inside. A limiting block 10 is slidably fitted inside each limiting groove 9, and the bottom surface of each limiting block 10 is fixed to the top surface of the fixed base 1. The limiting groove 9 is an inverted "convex" shape that cooperates with the limiting block 10. A shock-absorbing pad 11 that mates with the outer surface of the limiting block 10 is glued to the inner wall of the limiting groove 9. A fixing rod 12 is fixed on the mounting block 8 on both sides of each limiting groove 9, and a fixing plate 13 is rotatably sleeved on each fixing rod 12. Each fixing rod 12 is set as a horizontally placed "T" shape. Each fixing plate 13 has a limiting insertion hole that mates with the limiting insertion rod 14. A support block 17 is symmetrically fixed at one end of the limiting block 10 extending to the outer side of the mounting block 8. Each set of two fixing plates 13 is engaged inside the support block 17. The support blocks 17 are all set as "L" shapes that mate with the fixing plates 13. Each fixing plate 13 has a rotating hole that mates with the fixing rod 12 on its outer side.

[0023] Specifically, when it is necessary to install main pump 1 2, standby pump 3 or main pump 2 4, the mounting block 8 is placed on the limiting block 10 through the limiting groove 9. After the installation is completed, the fixing plate 13 is rotated so that the fixing plate 13 rotates under the support of the fixing rod 12 and engages inside the support block 17, thereby limiting the limiting block 10 and fixing the main pump 1 2, standby pump 3 and main pump 2 4 on the top surface of the fixing base 1. When the water source of inlet 1 5 cannot supply water in time, the one-way valve 7 on inlet 2 6 is opened, and water can be supplied through the water source connected to inlet 2 6, ensuring smooth water supply.

[0024] As an optimization solution, such as Figure 2 and Figure 3 As shown, the limiting block 10 has symmetrically opened movable slots 15 inside, and each movable slot 15 is slidably fitted with a limiting rod 14. Both the limiting rod 14 and the movable slot 15 are set as horizontally placed "T" shapes. The end of the limiting rod 14 that passes through to the outside of the fixed plate 13 abuts against the support block 17. The end of each limiting rod 14 that passes through to the outside of the limiting block 10 is inserted into the fixed plate 13. Each limiting rod 14 inside the movable slot 15 is threaded with a spring 16, and both ends of the spring 16 are fixed to the movable slot 15 and the limiting rod 14 respectively.

[0025] Specifically, after the limiting groove 9 is fitted onto the limiting block 10, before rotating the fixing plate 13, the limiting rod 14 is pressed, causing the limiting rod 14 to move the tension spring 16 into the limiting block 10. Then, the fixing plate 13 is rotated and locked into the support block 17. After locking, the pressing of the limiting rod 14 is released, and the limiting rod 14, driven by the spring 16, passes through the fixing plate 13 and abuts against the support block 17, ensuring the firmness of the connection between the main pump 1 2, the spare pump 3, and the main pump 2 4.

[0026] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
