Detailed Description
The invention is further illustrated with reference to the following figures and examples.
As shown in figure 1, the high-efficiency integrated prefabricated drainage pump station comprises a well body 1 and a well cover 2, wherein the well body 1 is integrally prefabricated and formed by adopting concrete so as to facilitate construction. The well lid 2 covers the opening of the well body 1 to prevent external impurities from falling into the well body 1.
The lower part of well body 1 is provided with retaining chamber 6 for the water that the storage needs to discharge, the lateral wall in retaining chamber 6 is provided with inlet tube 5, with let in outside ponding, and the bottom in retaining chamber 6 is provided with drain pump 3, and drain pump 3 can adopt the submerged sewage pump for the drainage, drain pump 3 is connected with drain pipe 4, and drain pipe 4 links to each other with the outside water drainage pipe network of well body 1.
The top in retaining chamber 6 is provided with supporting platform 7 that has the water hole, and supporting platform 7 is fixed to be set up, can supply the staff to stand to in the maintenance of equipment in the pit, the water hole is general hole promptly, as long as can supply water to pass through can.
The floating water pump cabin 8 is arranged on the supporting platform 7, the floating water pump cabin 8 can float on the water surface, an air cushion or a ship-shaped structure can be adopted, an upper drainage pump 9 is installed on the floating water pump cabin 8, and the upper drainage pump 9 is connected with a drainage pipe 4 through a hose 10. Upper drainage pump 9 is used for supplementary drainage, and is great when the inflow, when the water level reachd upper drainage pump 9's air pump water level, can start upper drainage pump 9, will float 8 below in water pump compartment and take out to hose 10 to get into drain pipe 4 through hose 10, accelerate drainage rate. The hose 10 can be a spiral flexible pipe which can be extended and retracted to adapt to the rising and falling of the floating water pump cabin 8.
The invention discloses a drainage method of an efficient integrated prefabricated drainage pump station, which comprises the following steps:
the outside water enters the water storage cavity 6 through the water inlet pipe 5, when the water inlet flow is small, the water level of the water storage cavity 6 is lower than that of the supporting platform 7, the lower drainage pump 3 is used for draining water, and the upper drainage pump 9 is kept closed.
When the inflow is large, the upper drainage pump 9 drains water, the water level of the water storage cavity 6 rises, when the water level reaches the supporting platform 7, the floating water pump cabin 8 moves upwards under the buoyancy of the water, the volume of the water storage cavity 6 is increased, the gravity of the floating water pump cabin 8 increases the water pressure, the drainage speed of the lower drainage pump 3 is increased, the upper drainage pump 9 is started, and the two water pumps drain water simultaneously.
Therefore, although the invention is provided with two drainage pumps, the two drainage pumps are arranged up and down instead of side by side, thereby increasing the drainage speed without increasing the floor space. In addition, the floating water pump cabin 8 can synchronously lift along with the water level, so that the volume of the water storage cavity 6 is automatically adjusted, and the water storage capacity of the water storage cavity 6 is enhanced. In addition, as is known, the higher the water pressure is, the higher the drainage speed of the lower drainage pump 3 is, and since the floating pump chamber 8 and the upper drainage pump 9 have certain weights, when the floating pump chamber 8 floats on the water surface, the weights of the floating pump chamber 8 and the upper drainage pump 9 increase the water pressure, thereby increasing the drainage speed of the lower drainage pump 3. A suitable counterweight may be provided on the floating pump compartment 8 to further increase the water pressure.
In order to ensure that the floating water pump cabin 8 can stably and automatically ascend and descend, the side wall of the well body 1 is provided with a plurality of sliding rails 11, the edge of the floating water pump cabin 8 is provided with a pulley, the pulley is matched with the sliding rails 11, and the vertical sliding rails 11 can play a role in guiding and positioning, so that the floating water pump cabin 8 can move up and down along the vertical direction.
An upper-layer maintenance platform 12 is arranged above the supporting platform 7, a ladder 13 is arranged between the opening of the well body 1 and the upper-layer maintenance platform 12, and the ladder 13 is also arranged between the upper-layer maintenance platform 12 and the supporting platform 7, so that a worker can conveniently go into a well to perform maintenance work.
The well lid 2 is provided with the ventilation pipe 14, and the ventilation pipe 14 communicates with the outside air for ventilation avoids the inside a large amount of accumulations of foul smell, poisonous and harmful gas in the well body 1.
A check valve 15 is arranged on the drain pipe 4 above the joint of the hose 10 and the drain pipe 4, and a one-way water inlet valve 16 is arranged at the inlet of the upper drain pump 9. The check valve 15 prevents the backflow of water and the one-way inlet valve 16 acts to block the flow of water from the upper drainage pump 9 back to the reservoir chamber 6. As known, when the pump is started, the pump needs to be filled with water to normally start the water pump, when the lower drainage pump 3 works, the water flows into the drainage pipe 4, flows into the hose 10 through the joint of the hose 10 and the drainage pipe 4, and then flows into the upper drainage pump 9, so that the upper drainage pump 9 is filled with water, and when the upper drainage pump 9 needs to be started, the upper drainage pump 9 can be started smoothly.
The outlet of the water inlet pipe 5 is provided with a crushing grid 17, and the crushing grid 17 is used for crushing sundries in water, such as branches and plastics, so that the water pump and the pipeline are prevented from being blocked by the bulky sundries. In order to facilitate installation of the comminuted grate 17, a vertical grate guide column 18 is arranged in the well body 1, and the comminuted grate 17 is in sliding fit with the grate guide column 18. When the shatter grating 17 is installed, the shatter grating 17 slides to the water inlet pipe 5 along the grating guide column 18 and is connected with the water inlet pipe 5, when the shatter grating 17 needs to be removed, the connection between the shatter grating 17 and the water inlet pipe 5 is released, the shatter grating 17 is lifted upwards, and the operation is convenient.
In order to facilitate the installation of the lower drainage pump 3, a vertical guide rail 19 is arranged in the well body 1, and the lower drainage pump 3 is in sliding fit with the lower drainage pump 3.
Because the height of the well body 1 is limited, or according to the local drainage requirement, the floating water pump cabin 8 has a maximum height, for example, in a pump station which penetrates a tunnel, the maximum water level of the pump station cannot exceed a specified early warning water level, when the floating water pump cabin 8 reaches the maximum height, if the drainage speed of two water pumps is still less than the water inlet speed of the water inlet pipe 5, the function of the pump station is disabled, therefore, at the maximum height which can be reached by the floating water pump cabin 8, the side wall of the well body 1 is provided with an overflow drain pipe 20, when the water level reaches the overflow drain pipe 20, water is discharged from the overflow drain pipe 20 to a shallow pipe network, a river or other pump stations, the water level is prevented from continuously rising, and the safety of the pump station is ensured.
The ground where the well body 1 is located is provided with a fence to play a role in protection, and meanwhile, a control cabinet is arranged on the ground beside the well body 1 to control the operation of each power device.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
