[0013] As a preferred technical solution of the present invention, a mounting groove is provided inside the bottom plate, and a fixing rod is installed inside the mounting groove.

[0014] As a preferred technical solution of the present invention, first springs are sleeved on both sides of the outer surface of the fixed rod, one end of two of the first springs are fixedly connected to the inner wall of the mounting groove, one end of the two first springs are fixedly installed with moving blocks, the two moving blocks are slidably connected to the fixed rod, and second hinged seats are installed on the top of the two moving blocks, and the two second hinged seats are hingedly connected to the two hinged rods.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The bulk carrier engine room wall pump unit is provided with a fixed base and an inner groove. When the device is installed, the fixed base is fixed in the lower pier of the transverse bulkhead, and the ship bottom general pump, the bilge sweeping jet pump, the ballast pump, the fire fighting general pump, and the main cooling seawater pump can be placed at any position on the top of the fixed base. The bottom of each pump is fixed from the inner groove by bolts, so as to solve the problem that the stern of the bulk carrier is tightened, the space in the engine room is small, the equipment arrangement in the engine room cannot be optimized, and the length of the engine room cannot be reduced. At the same time, under the condition that the ship length remains unchanged, the cargo hold length is increased, the cargo loading capacity of the bulk carrier cargo hold is increased, and the economy of the ship structure is improved;

[0017] 2. The bulk carrier engine room wall pump unit, through the protective structure, fixes each pump on the top of the fixed base, and protects the inner groove through the baffle. When the pump unit needs to be removed for maintenance, the fastening bolts on both sides are loosened and removed. After the two fastening bolts are removed, the moving plate is slid to make the baffle detach from the side of the fixed base, and the baffle is turned over to make it parallel to the fixed base. At this time, the pump can be removed for maintenance. When not in use, the baffle is reset and the clamping column is clamped in the clamping groove to fix it;

[0018] 3. The bulk carrier engine room wall pump group has a vibration-absorbing structure. When the device is installed, the device is fixed in the pier under the transverse bulkhead. Since multiple pumps work simultaneously and generate large vibrations and relatively large noises, when the pump drives the fixed base to vibrate, the movable column is first driven to move in the sleeve column, and the first step of buffering is achieved through the compression of the second spring. At the same time, the second hinged seat is squeezed by the hinged rod, so that the two moving blocks can slide to both sides and squeeze the first spring to shrink it, thereby achieving the second step of buffering. The noise generated by vibration is greatly reduced through the two-step buffering. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] After each pump is fixed on the top of the fixed base 1, the inner groove 102 is protected by the baffle 25. When the pump group needs to be removed for maintenance, the fastening bolts 23 on both sides are loosened and removed. After the two fastening bolts 23 are removed, the movable plate 22 is slid to make the baffle 25 separate from the side of the fixed base 1, and the baffle 25 is turned over to make it parallel to the fixed base 1. At this time, the pump can be removed for maintenance. When not in use, the baffle 25 is reset and the clamping column 27 is clamped in the clamping groove 103 to fix it.

[0031] See also Figure 6-7 A damping structure 3 is provided at the bottom of the fixed base 1. The damping structure 3 includes two first hinge seats 31 and a bottom plate 33. The two first hinge seats 31 are provided at the bottom of the fixed base 1. A hinge rod 32 is installed at the intersection of the two first hinge seats 31. The bottom plate 33 is provided below the fixed base 1. Extensions 34 are installed on both sides of the outer surface of the bottom plate 33. Two locking holes 35 are provided inside the two extensions 34. Four sleeves 311 are installed on the top of the bottom plate 33. Active columns 312 are movably installed inside the four sleeves 311.

[0032] The device is fixed in the pier under the transverse bulkhead. Since multiple pumps work simultaneously, large vibrations and relatively large noises are generated. When the pump drives the fixed base 1 to vibrate, the movable column 312 is first driven to move in the sleeve column 311, and the first step of buffering is achieved through the compression of the second spring 313. At the same time, the second hinge seat 310 is squeezed by the hinge rod 32, so that the two moving blocks 39 can slide to both sides and squeeze the first spring 38 to shrink it, thereby achieving the second step of buffering. The noise generated by the vibration is greatly reduced through the two-step buffering.

[0033] Working principle, when the bulk carrier engine room wall pump group is used, in the initial state, first the transverse bulkhead is set to be a double-hull watertight bulkhead, the bottom stool and the top stool are retained, and a passage is provided in the double-hull bulkhead to facilitate the staff to enter the lower pier of the transverse bulkhead to inspect the pump group equipment, and then the fixed base 1 is fixed in the lower pier of the transverse bulkhead.

At the same time, under the condition that the ship length remains unchanged, the cargo hold length is increased, the loading capacity of the bulk carrier cargo hold is increased, and the economy of the ship structure is improved. When each pump is working, When multiple pumps work simultaneously, large vibrations and relatively large noises are generated. When the pump drives the fixed base 1 to vibrate, the movable column 312 is first driven to move in the sleeve column 311, and the first step of buffering is achieved by compressing the second spring 313. At the same time, the second hinge seat 310 is squeezed by the hinge rod 32, so that the two movable blocks 39 can slide to both sides and squeeze the first spring 38 to shrink it, thereby achieving the second step of buffering. The two-step buffering greatly reduces the noise generated by vibration. When the pump needs to be repaired, the fastening bolts 23 on both sides are loosened and removed. After removing the two fastening bolts 23, the movable plate 22 is slid to separate the baffle 25 from the side of the fixed base 1, and the baffle 25 is flipped to make it parallel to the fixed base 1. At this time, the pump can be dismantled for maintenance. When not in use, the baffle 25 is reset and the clamping column 27 is clamped in the clamping groove 103 for fixation.
