[0027] like Figures 1 to 7As shown, this embodiment discloses a mobile pump room, including a pump room body 1, a main water pump 2, a pressure-stabilizing pump 3, a water inlet pipe 4 and a water outlet pipe 5 installed in the pump room body 1, at least two main water pumps 2 are provided, the water inlet end of the main water pump 2 is connected to the water inlet pipe 4, one end of the water inlet pipe 4 extends to the outside of the pump room body 1 to form a water inlet 41 for connecting to an external water supply pipeline, and the other end of the water inlet pipe 4 is blocked; the water outlet end of the main water pump 2 is connected to the water outlet pipe 5, and the water outlet pipe 5 One end of the pump room extends to the outside of the pump room body 1 to form a water outlet 51 for connecting to an external fire-fighting pipeline, and the other end of the outlet pipe 5 is blocked; the water inlet end and the water outlet end of the pressure-stabilizing pump 3 are respectively connected to the water inlet pipe 4 and the water outlet pipe 5, and the pressure-stabilizing pump 3 is used to assist the main water pump 2 in supplying water and stabilize the water supply flow and water pressure of the main water pump 2; the main water pump 2 and the pressure-stabilizing pump 3 are arranged in parallel; the water inlet pipe 4 is connected with a flow meter 6 for detecting the flow rate and a pressure gauge 7 for detecting the water pressure, and the flow meter 6 and the pressure gauge 7 are connected to the water inlet pipe 4. The flow meter 7 is connected to the water inlet pipe 4 near the end of the water inlet 41; a control cabinet 8 for controlling the overall operation of the pump room is installed in the pump room body 1, and the flow meter 6 and the pressure gauge 7 send the detected flow signal and water pressure signal to the control cabinet 8, and the control cabinet 8 controls the operation of the pressure-stabilizing pump 3 according to the flow signal and the water pressure signal; the water outlet pipe 5 is connected to a diaphragm air pressure tank 9 for automatically balancing the water pressure, and the diaphragm air pressure tank 9 is connected to the water outlet pipe 5 near the end of the water outlet 51. When in use, The water outlet pressure set by the water outlet pipe 5 injects constant gas into the air chamber of the diaphragm air pressure tank 9 to make the internal air pressure constant. At the same time, water is added to the water chamber of the diaphragm air pressure tank 9. When the water pressure of the water outlet pipe 5 drops, the diaphragm air pressure tank 9 supplies water to the water outlet pipe 5 to increase the water pressure of the water outlet pipe 5; and when the water pressure of the water outlet pipe 5 increases, part of the water in the water outlet pipe 5 enters the diaphragm air pressure tank 9 to reduce the water pressure of the water outlet pipe 5; therefore, the diaphragm air pressure tank 9 plays a role in balancing and regulating the water pressure of the water outlet pipe 5. The mobile pump room of the present embodiment improves the water supply stability of the mobile pump room by configuring a pressure-stabilizing pump 3 in the pump room body 1. The pressure-stabilizing pump 3 assists the main water pump 2 in its operation. When the main water pump 2 cannot make the flow rate and water pressure of the mobile pump room meet the water supply demand, the pressure-stabilizing pump 3 works to increase the flow rate and water pressure to a state that meets the water supply demand. The pressure-stabilizing pump 3 is used for regulating the flow rate and water pressure at the front end of the water inlet pipe 4 of the mobile pump room to achieve a pressure stabilizing effect. A diaphragm air pressure tank 9 is connected to the water outlet pipe 5 to balance the water outlet flow rate and pressure through automatic adjustment, so that the water outlet flow rate and pressure of the mobile pump room remain stable, thereby ensuring the stability of the water supply in the pump room.

[0028] In this embodiment, in order to prevent the water entering the mobile pump room from flowing back out from the water inlet pipe 4, the water inlet pipe 4 is provided with a one-way valve 10 for preventing water from flowing back. The one-way valve 10 is arranged in the water inlet pipe 4 near one end of the water inlet 41, so that the water in the mobile pump room can only flow from the water inlet pipe 4 to the water outlet pipe 5, but cannot flow in the opposite direction.

[0029] In the present embodiment, since the volume of the diaphragm air pressure tank 9 is relatively large, the diaphragm air pressure tank 9 is arranged outside the pump room body 1. At this time, the pump room body 1 does not need to accommodate the diaphragm air pressure tank 9, and the volume is relatively small, which is easy to transport and transfer; of course, when the volume of the diaphragm air pressure tank 9 is relatively small, the diaphragm air pressure tank 9 can also be installed inside the pump room body 1. At this time, all pipelines and equipment of the mobile pump room are integrated in the pump room body 1, and can be directly placed on the site of use to connect the external water supply pipeline and the fire-fighting pipeline. There is no need to assemble the mobile pump room, and the use convenience is relatively high.

[0030] In this embodiment, the side wall panel of the pump room body 1 is installed with an exhaust fan 20 for ventilation and exhaust inside the pump room body 1; the interior of the pump room body 1 is provided with a lighting lamp 30 for providing lighting for the interior of the pump room body 1, preferably, the lighting lamp 30 is installed on the top wall inside the pump room body 1.

[0031] In this embodiment, in order to facilitate the lifting of the mobile pump room, a lifting ring 11 is provided on the top of the pump room body 1. When the diaphragm air pressure tank 9 is arranged outside the pump room body 1, a lifting ring 11 is also provided on the top of the diaphragm air pressure tank 9.

[0032] In this embodiment, in order to facilitate the movement of the mobile pump room, a mobile wheel set 12 is arranged at the bottom of the pump room body 1, and the mobile wheel set 12 can be used to push the mobile pump room to move on the ground, so as to facilitate the position adjustment of the mobile pump room. Specifically, a downwardly protruding positioning convex strip 13 is provided at the bottom of the pump room body 1, and the mobile wheel set 12 includes a wheel set frame 121 and a roller 122, and the roller 122 is fixed to the bottom of the wheel set frame 121, and a positioning cavity 123 with a top opening is provided in the wheel set frame 121, and the positioning cavity 123 is adapted to the positioning convex strip 13, and the wheel set frame 121 is positioned and installed with the pump room body 1 by being set on the outside of the positioning convex strip 13 through the positioning cavity 123, and a support strip 124 for supporting the bottom surface of the positioning convex strip 13 is provided at the bottom of the positioning cavity 123.

[0033] In this embodiment, a bottom plate 14 is provided at the bottom of the pump room body 1. Since the main water pump 2, the pressure-stabilizing pump 3, the control cabinet 8 and other equipment inside the pump room body 1 are installed on the bottom plate 14, the bottom plate 14 needs to have a certain load-bearing capacity and structural strength. Therefore, the bottom plate 14 of this embodiment includes an upper plate 141, a lower plate 142 and a structural layer. The structural layer is arranged between the upper plate 141 and the lower plate 142. The structural layer includes two relatively arranged cross bars 143 and two relatively arranged longitudinal bars 144. The two cross bars 143 and the two longitudinal bars 144 are arranged on the bottom plate 141. The longitudinal rods 144 are alternately connected through connecting angle pieces 145 to form a rectangular frame structure. An X-shaped reinforcement frame 146 is also provided inside the structural layer. The four connecting ends of the X-shaped reinforcement frame 146 are respectively connected to the four connecting angle pieces 145. The connecting angle piece 145 is provided with a first connecting end for connecting the crossbar 143, a second connecting end for connecting the longitudinal rod 144, and a third connecting end for connecting the X-shaped reinforcement frame 146. The first connecting end is vertically arranged with the second connecting end, and the third connecting end is arranged within the angle between the first connecting end and the second connecting end. In addition, a column 15 extending up and down is provided at the corner of the side wall of the pump room body 1. The connecting angle piece 145 is provided with a connecting hole 147 for the column 15 to be inserted and fixed. When the column 15 is installed, one end of the column 15 is inserted into the connecting hole 147, and a fixing bolt is inserted on the outer side of the connecting angle piece 145 to fix the column 15 in the connecting hole 147. By setting the structural layer, the overall load-bearing capacity and structural strength of the base plate 14 are improved, and by connecting the cross bar 143, the longitudinal bar 144, the X-shaped reinforcement frame 146 and the column 15 through the connecting angle piece 145, the installation is more convenient and the assembly efficiency of the base plate 14 can be improved.

[0034] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the protection scope of the present invention.
