Description

Technical Field

[0001] The utility model relates to the technical field of fire pumps, in particular to a fire pump capable of outputting water over a long distance. Background Art

[0002] In firefighting and rescue, it is inevitable that the fire pump is too far away from the fire site or the fire occurs in a high-rise building, so a fire pump that can achieve long-distance water supply is essential. When the fire site is far away from the fire pump, the terminal equipment is generally arranged near the fire site, and the water intake fire pump body, pressurized fire pump body and terminal fire pump body of the water intake equipment are connected in sequence through pipelines, and multi-stage pressurization is performed to achieve long-distance water supply.

[0003] Long-distance water supply generally requires a multi-stage booster fire pump to increase the head to meet the long-distance water supply transmission. However, high-head fire pumps also bring safety hazards when working. The high-head fire pump has a high water discharge pressure, which can easily cause the fire hose to fall off or even burst due to overpressure, causing damage to fire equipment.

[0004] This case was created to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide a fire pump which can output water over a long distance, so as to solve the problems raised in the above-mentioned background technology.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a fire pump that can output water over a long distance, including a fire pump body, two parallel water outlet pipes are connected to the fire pump body, the two water outlet pipes are connected to a transition pipe, the transition pipe is connected to a threaded connection seat, and is connected to a water hose through the threaded connection seat, and a separate valve is provided on one of the two water outlet pipes.

[0009] Preferably, the transition pipe is tapered, one end of which is connected to the two water outlet pipes, and the other end of which is contracted and connected to the threaded connection seat.

[0010] Preferably, a water hose fixing mechanism is provided on the threaded connection seat, and the water hose fixing mechanism includes a connection base, and an extension sleeve is provided on the connection base. The extension sleeve extends in the direction of the water hose, and the end of the extension sleeve is connected to a water hose fixing pipe.

[0011] Preferably, the connecting base is movable on the transition pipe.

[0012] Preferably, the inner diameter of the water hose fixing pipe is equal to the diameter of the water hose.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is a fire pump that can output water source for a long distance, and two water outlet pipes are arranged. When the water source needs to be output for a long distance, the water outlet pipe with a separate valve can be opened, and the water pump power can be increased to increase the outlet dynamic pressure. At the same time, the conical transition pipe can absorb a certain outlet water pressure and reduce the impact of water on the water hose. The arranged water hose fixing mechanism can prevent the water hose from falling out when it is impacted by water pressure. When transporting over a short distance, there is no need to open the valve, thereby reducing the outlet dynamic pressure and the pressure of the threaded seat, which is safer and more efficient.

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] The utility model provides a fire pump capable of outputting water over a long distance. Figure 1-4 As shown, the fire pump body 1 includes two parallel water outlet pipes 2 connected to the fire pump body 1, the two water outlet pipes 2 are connected with a transition pipe 3, the transition pipe 3 is connected with a threaded connection seat 4, and is connected to the water hose through the threaded connection seat 4. A separate valve 5 is provided on one of the two water outlet pipes 2. When two water outlet pipes 2 are set, when the belt needs to output water over a long distance, the water outlet pipe 2 with the separate valve 5 can be opened. The separate valve 5 is also electrically connected to the water pump. When the separate valve 5 is opened, the water pump power will increase to increase the outlet dynamic pressure. It should be noted that the main water inlet valve is not shown in the figure, and the valve does not need to be opened for short-distance transportation, which reduces the outlet dynamic pressure and the pressure of the threaded seat, making it safer and more efficient.

[0022] Reference Figure 2-3The transition pipe 3 is tapered, one end of which is connected to the two water outlet pipes 2, and the other end is contracted and connected to the threaded connection seat 4. The tapered transition pipe 3 can absorb a certain outlet water pressure and reduce the impact of water on the water belt.

[0023] Reference Figure 2-4 A water hose fixing mechanism is provided on the threaded connection seat 4, and the water hose fixing mechanism includes a connection base 6, and an extension sleeve 7 is provided on the connection base 6. The extension sleeve 7 extends in the direction of the water hose, and the end of the extension sleeve 7 is connected to a water hose fixing pipe 8. The inner diameter of the water hose fixing pipe 8 is equal to the diameter of the water hose. The set water hose fixing mechanism can prevent the water hose from falling out when it is impacted by water pressure.

[0024] Reference Figure 3-4 The connecting base 6 can be moved on the transition pipe 3. When installing the water hose, first move the connecting base 6 together with the entire water hose fixing mechanism to the place closest to the water pump. After the water hose is fixed to the threaded connecting seat 4, fit the connecting base 6 to the threaded connecting seat 4 and fix them with bolts.
