Because the mesh enclosure 3 is located in seawater and the flow direction of water flow in the sea is complex, after the spacer 32 is impacted in the sea, one end, far away from the water wheel 21, of the spacer 32 is close to the direction of the rotary table 22, the spacer 32 compresses the spring 23 to deform, the spacer 32 is made of elastic materials, such as rubber or stainless steel materials, and the water intake head 2 is rotationally connected with the mounting seat 11, so that the water intake head 2 is easy to rotate when impacted by the water flow, the spacer 32 is dislocated with the direction of the water flow when the water intake head 2 rotates, the spring 23 loses extrusion and rebounds, and the spacer 32 drives the mesh 31 to shake and shake off sundries adhered to the mesh 31;
meanwhile, the mesh enclosure 3 is designed in a mode of mesh sheets 31 and spacers 32, and the mesh enclosure 3 intercepts organisms such as fishes and shrimps in the sea;
because the water intaking head 2 is certain suction when drawing water, net piece 31 is close to the direction of water intaking head 2, can design different screen panel 3 patterns to different waters for net piece 31 does not contact with the outer wall of water intaking head 2 when drawing water, and net piece 31 that net piece 31 lies in spacer 32 both sides mutually not contact when the water pump is out of work.
When the water pump is used for pumping water, the water flow drives the water wheel 21 to rotate, the water wheel 21 drives the sweeping roller 41 to rotate in the rotating process, the sweeping roller 41 cleans the surface of the rotating sleeve 43 through the brush 42 in the rotating process, the brush 42 is located inside the water intake head 2, the brush 42 is in contact with the rotating sleeve 43 in the rotating process and enables the rotating sleeve 43 to rotate, one side of the rotating sleeve 43, which is close to the net cover 3, rotates to the inside of the water intake head 2, and the brush 42 cleans the rotating sleeve 43 comprehensively.
Although the brush 42 cleans the rotating sleeve 43 under the driving of the water wheel 21, the impurities attached to the rotating sleeve 43 can be cleaned to a certain extent, but the water intake head 2 is blocked by the larger plants growing in the ocean along with the flowing of water flow; at this time, the air in the air pipe 5 can be conveyed by an external air pump, so that the air in the air pump is discharged through the air hole 51 and the jet hole 44 to impact and crush the large plants blocked on the water intake head 2;
a monitor can be arranged in the water intake head 2 and is connected with an electrical system, and when the monitor detects that the flow rate of seawater flowing through the water intake head 2 is lower than a set value, the electrical system starts an air pump to enable the air pump to work; the set value is calculated according to the flow rates of the seawater in different areas, and the air pump is electrically connected with the electric system;
the injection holes 44 are generally flared in shape so as to produce a certain compression of the gas injected in the air holes 51, thus increasing the kinetic energy of the injection and better crushing the macrophytes blocked on the water intake head 2.
Because the intake head 2 is located the sea water, silt in the sea water is because the volume of itself is too tiny to get into the junction on water wheels 21 and the 2 inner walls of intake head easily, makes water wheels 21's rotation obstructed along with the increase of silt volume, installs ball 24 on water wheels 21 and reduces the area of contact of water wheels 21 and 2 inner walls of intake head.
The main components of the glass block 33 are silicon dioxide and other oxides, while seawater is alkaline, the silicon dioxide reacts with alkaline substances to generate silicate, the main organisms attached to the water intake head 2 in the ocean are barnacles, and the Ca + in the silicate can inhibit the attachment of barnacle larvae; on the other hand, the existence of the basic silicate enables the pH value of the seawater environment around the net cover 3 to be increased, so that the seawater environment near the net cover 3 is not suitable for the growth of barnacles.
The elastic material can be made of a nylon elastic rope; the nylon elastic rope has good wear-resisting and corrosion-resisting properties, and meanwhile, the nylon elastic rope is stretched to have a memory of returning to the original length; so that the retraction can be carried out after the impact of the water flow in the sea water.
