Below in conjunction with accompanying drawing, technological scheme of the present invention is carried out detailed explanation.
As shown in Figure 1, a kind of buoyancy module formula Submerged Motor Pumps that is used for water body of the present invention comprises the pump housing 1 and buoyancy module 2.Buoyancy module comprises buoyancy module loam cake 201, buoyancy module lower cover 202, outer bulkhead 203 and outlet pipe 204.Outer bulkhead 203 is positioned at the outside of outlet pipe 204, and outer bulkhead 203 is all stretched out in the top of outlet pipe 204 and bottom.Form toroidal cavity between outer bulkhead 203 and the outlet pipe 204.Buoyancy module loam cake 201 is positioned at outer bulkhead 203 tops, and is fixedly connected the top of outer bulkhead 203 and the top of outlet pipe 204.Buoyancy module lower cover 202 is positioned at outer bulkhead 203 belows, and is fixedly connected the bottom of outer bulkhead 203 and the bottom of outlet pipe 204.Through buoyancy module loam cake 201 and buoyancy module lower cover 202 are set, the toroidal cavity between outer bulkhead 203 and the outlet pipe 204 is an air-tight state.The periphery of buoyancy module loam cake 201 is provided with first through hole 205, and this first through hole 205 is positioned at outer bulkhead 203 outsides.It mainly is for cable wire is installed that first through hole 205 is set.First through hole, 205 quantity can be used according to reality and decide, and preferred three to six, and first through hole 205 is evenly distributed on the periphery of buoyancy module loam cake 201.The periphery of buoyancy module lower cover 202 is provided with second through hole 206, and this second through hole 206 is positioned at outer bulkhead 203 outsides.It mainly is for cable wire is installed that second through hole 206 is set.The top of outlet pipe 204 is provided with upper flange plate 207, is provided with third through-hole 208 in the upper flange plate 207, and this third through-hole 208 is positioned at outlet pipe 204 inboards.Third through-hole 208 is communicated with outlet pipe 204 with extraneous.Third through-hole 208 mainly is to be used for connecting outlet pipe 204 and the rising pipe that is positioned at the Submerged Motor Pumps outside.The bottom of outlet pipe 204 is provided with lower flange 209.Be provided with into water exhaust hole 211 in the buoyancy module loam cake 201, this water inlet exhaust hole 211 is positioned at outer bulkhead 203 inboards.Water inlet exhaust hole 211 can be controlled the gas flow of the cavity between outer bulkhead 203 and the outlet pipe 204, so that regulate the buoyancy of buoyancy module 2.The top of outlet pipe 204 is provided with cable outlet hole 212, and this cable outlet hole 212 is positioned at buoyancy module loam cake 201 tops.Pass cable outlet hole 212, can electricity be pulled an end of 10 and be connected on the pump housing 1, the other end is connected on the power supply.Through the unlatching of control power supply, and then make the pump housing 1 work.The end face of buoyancy module loam cake 201 is fixedly connected with anchoring pile 213.The pump housing 1 is vertically placed, and the pump housing 1 is arranged in outlet pipe 204, and the pump housing 1 is fixedly connected on the lower flange 209.
Further, in order to make the Submerged Motor Pumps structure firm, the described buoyancy module formula Submerged Motor Pumps that is used for water body also comprises gusset 3, and last gusset 3 is positioned at buoyancy module loam cake 201 tops, and is fixedly connected on the outer wall of end face and outlet pipe 204 of buoyancy module loam cake 201.The described buoyancy module formula Submerged Motor Pumps that is used for water body also comprises lower web plate 4, and lower web plate 4 is positioned at buoyancy module lower cover 202 belows, and is fixedly connected on the outer wall of bottom surface and outlet pipe 204 of buoyancy module lower cover 202.Through gusset 3 and lower web plate 4 are set, between buoyancy module loam cake 201 and the outlet pipe 204, and the connection between buoyancy module lower cover 202 and the outlet pipe 204 will be more firm.
Like Fig. 2, Fig. 3 and shown in Figure 4; The installation method of the above-mentioned buoyancy module formula Submerged Motor Pumps that is used for water body; May further comprise the steps: at first; Cable wire is installed: an end of fixing first cable wire 214 in one first through hole 205 of buoyancy module loam cake 201, an end of fixing second cable wire 215 in one second through hole 206 of buoyancy module lower cover 202; Then; On the bank; Buoyancy module formula Submerged Motor Pumps was fallen, and the side margin of the side margin of buoyancy module loam cake 201 and buoyancy module lower cover 202 all lands, and controls the free end of first cable wire 214 and the free end of second cable wire 215 through the people; Make the littoral slope 5 of buoyancy module formula Submerged Motor Pumps glide, slip in the water body 6 until buoyancy module formula Submerged Motor Pumps; Then; From second through hole 206, untie second cable wire 215; And an end of second cable wire 215 is fixed in second first through hole 205; One end of the 3rd cable wire 210 is fixed in the 3rd first through hole 205, again the free end of first cable wire 214 and the free end of second cable wire 215 is separately fixed on the bank slope 5, and first cable wire 214 and second cable wire 215 all are curved shape; At last, fixing the 3rd cable wire 210: on mooring anchor 7, connect an end of the cable wire 8 of weighing anchor, and the free end of the 3rd cable wire 210 is fixed on the bottom 9 with mooring anchor 7, the other end of the cable wire 8 of weighing anchor is fixed on the anchoring pile 213.
In the above-mentioned installation process; When the littoral slope of buoyancy module formula Submerged Motor Pumps slides in the water body 65 times; Because the pump housing 1 vertically is placed in the outlet pipe 204; And the bottom of the pump housing 1 is fixedly connected on the lower flange 209, so under the action of gravity of the buoyancy of buoyancy module 2 and the pump housing 1, buoyancy module formula Submerged Motor Pumps will vertically swim in the water body 6 voluntarily.
After first cable wire 214 and second cable wire 215 were fixed on the bank slope 5, first cable wire 214 and second cable wire 215 all were curved shape.That is to say that first cable wire 214 and second cable wire 215 all are not in exceptionally straight state.Fixing first cable wire 214 and second cable wire 215 are in order to prevent that buoyancy module formula Submerged Motor Pumps is parallel to the drift of bank slope 5.Again because first cable wire 214 and second cable wire 215 all are not in exceptionally straight state, so buoyancy module formula Submerged Motor Pumps can be along with the floating work of water level height.One end of the 3rd cable wire 210 is fixed in first through hole 205, and the other end of the 3rd cable wire 210 is fixed on water-bed 9 with mooring anchor 7.It is in order to prevent that buoyancy module formula Submerged Motor Pumps from the drift perpendicular to bank slope 5 taking place that the 3rd cable wire 210 is set.First cable wire 214, second cable wire 215 and the 3rd cable wire 210 are set simultaneously can prevent that buoyancy module formula Submerged Motor Pumps from rotating.The end of cable wire 8 of weighing anchor is connected on the mooring anchor 7, and the other end of the cable wire 8 of weighing anchor is fixed on the anchoring pile 213.The cable wire 8 of weighing anchor is not in exceptionally straight state.The setting cable wire 8 of weighing anchor is to use in order to weigh anchor.
The littoral slope of buoyancy module formula Submerged Motor Pumps is slided in the water body 6 for 5 times, fixed, connect rising pipe and cable, get final product commissioning test.The running of Submerged Motor Pumps in water body 6 is: during the Submerged Motor Pumps operation, water is drawn out of from the pump housing 1 bottom, discharges from outlet pipe 204, and through the rising pipe that is connected with upper flange plate 207 water is transported to the place that needs are carried.In when operation, because 214 one-tenth curved shapes of fixing tightwire 214 and fixing tightwire leave extending amount, so during water body 6 fluctuation in stages, Submerged Motor Pumps can fluctuate, and proper functioning.
Further, for firm buoyancy module formula Submerged Motor Pumps, the angle between first cable wire 214 and second cable wire 215 be 40 degree to 140 degree, for example can be 40 degree, 60 degree, 90 degree, 120 degree or 140 degree.
