Description

Technical Field

[0001] The invention relates to the technical field of groundwater intake pump houses, in particular to a shore-side energy-saving groundwater intake pump house. Background Art

[0002] In recent years, with the development of all walks of life in society, the total water consumption has increased sharply, and the over-development of groundwater will cause serious funnel phenomenon in slopes and cities, which will cause damage to the project at the least and cause casualties at the worst. Although surface water resources are abundant, there are many sources of surface water pollution and the water quality is worse than groundwater. At the same time, the surface water of rivers and lakes is often seriously affected by floods and droughts. The water volume, water quality and water level are particularly unstable, which brings certain difficulties to the water intake engineering of water supply projects.

[0003] A Chinese patent application with publication number CN211228711U discloses a groundwater supplementary water intake device, which includes an underground water intake structure and a water intake pump; the device also includes a surface water diversion system, a water purification device and a backwashing system; the main structure of the underground water intake structure is cylindrical, and an equipment room is isolated and arranged inside to be dedicated to placing and maintaining the water purification device, and a pedestrian staircase is arranged, which is fixed on the side wall of the underground water intake structure and respectively connects the pedestrian staircase entrance at the top of the underground water intake structure and the equipment room at the bottom of the underground water intake structure; The surface water diversion system includes a water intake head and a water diversion pipeline, wherein the water intake head is installed at the starting end of the water diversion pipeline, passes through the side wall of the water intake structure in the middle, and the end is connected to the water inlet end of the water purification device, and the water outlet end of the water purification device extends into the groundwater through the water outlet pipeline; the backwash system includes a backwash pump and a backwash pipeline, wherein the backwash pump is built under the groundwater level in the underground water intake structure and is connected to the water outlet pipeline in the water purification device through the backwash pipeline; the water diversion pipeline in the surface water diversion system is laid radially around the underground water intake structure. The water intake device achieves the purpose of filtering surface water and supplementing groundwater by setting up a surface water diversion system and a water purification device. However, in the device, when the surface water is relatively high or the groundwater resources are relatively abundant, the water level in the underground water intake structure, that is, the water level in the water intake pump room, will rise. As the water level in the water intake pump room rises, the actual head of the water intake will gradually decrease, which leads to the situation that the head margin of the water intake pump gradually increases and becomes excessive, resulting in a large demand for municipal electricity in the pump room, more energy waste, and high operating costs. In addition, the existing water intake pump room generally relies entirely on municipal power supply for lighting, water lifting, etc., which also increases its operating costs.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figures 1 to 3As shown, a shore energy-saving groundwater pump house of the present invention comprises a water pump 9, a battery 3, a turbine generator 5, a water outlet pipe 6 and a water pump house body 1 arranged on the shore of a river 10. The inner cavity of the water pump house body 1 forms a water replenishment chamber 2 connected to the river 10, and the water replenishment chamber 2 is also provided with a floating platform 7 which is vertically slidably connected to the water pump house body 1 through a track so as to float up and down with the change of the water level in the water replenishment chamber 2. The turbine generator 5 is installed on the floating platform 7, and the connection terminal of the turbine generator 5 is electrically connected to the battery 3 to charge the battery 3, and the battery 3 is electrically connected to the water pump 9 to supply power to the water pump 9. The water replenishment chamber 2 is provided with a water intake pipe well 11 for taking groundwater, which is arranged below the floating platform 7 and extends downward to the groundwater aquifer 16. The water replenishment chamber 2 is also provided with a water replenishment channel 12, which is connected to the water replenishment chamber 2 at one end and connected to the groundwater aquifer 16 at the other end. The water replenishment channel 12 is provided with a filter medium 13 to filter the surface water seeping downward. A water intake inner pipe 111 is fixedly installed in the water intake pipe well 11, and the water intake inner pipe 111 is sealed with the water intake pipe well 11. The water intake pump 9 is installed in the water intake pipe well 11 and the water outlet of the water intake pump 9 is connected to the lower end of the water intake inner pipe 111. The upper end of the water intake inner pipe 111 is inserted with a telescopic pipe 112 whose lower end slides and seals with it so that it can be telescoped up and down. The upper end of the telescopic pipe 112 is connected to the water inlet of the hydro-generator 5, and the water outlet of the hydro-generator 5 is connected to the water inlet end of the water outlet pipe 6 through the first branch pipe 61. The water inlet end of the water outlet pipe 6 is connected between the two ends of the water intake inner pipe 111 through the second branch pipe 62. The first branch pipe 61 and the second branch pipe 62 are respectively provided with an on-off control valve 63.

[0030] In order to facilitate the taking of river water, it can be understood that the setting position of the water replenishment chamber 2 should generally be lower than the lowest water level line of the river 10 during the dry season. In order to prevent the floating platform 7 from being flooded, it can be understood that the floating height of the floating platform 7, that is, the maximum height position of the floating platform 7 sliding upward is generally higher than the highest water level line of the river during the flood season.

[0031] The purpose of the sealing cooperation between the water intake inner tube 111 and the water intake pipe well 11 is to prevent river water from directly entering the water intake pipe well 11 through the gap between the two, and the purpose of the sealing cooperation between the telescopic tube 112 and the water intake inner tube 111 is to prevent water from penetrating into the water intake inner tube 111 from the gap between the two. The sealing cooperation between the telescopic tube 112 and the water intake inner tube 111 and between the water intake inner tube 111 and the water intake pipe well 11 can be achieved by a sealing member, such as a rubber ring.

[0032] The water replenishment chamber 2 of the bank energy-saving groundwater pump house of the present invention is connected to the river 10, and the river water (surface water) can enter the water replenishment chamber 2. The water replenishment chamber 2 is also provided with a water replenishment channel 12, one end of which is connected to the water replenishment chamber 2 and the other end is connected to the groundwater aquifer 16. When the groundwater is insufficient, the river water will infiltrate along the water replenishment channel 12 after entering the water replenishment chamber 2 and enter the groundwater aquifer 16, thereby replenishing the groundwater and entering the water intake pipe well 11. The filter medium 13 arranged in the water replenishment channel 12 plays a role in filtering the infiltrated river water. The groundwater in the groundwater aquifer 16 can be stored in the water intake pipe well 11 after seeping out. When water is needed, the water intake pump 9 is started to make the groundwater flow out of the outlet pipe 6 after passing through the first branch pipe 61 or the second branch pipe 62. When designing the pump room, the water pump 9 with the corresponding head will be selected according to the lowest water level line in the water intake pipe well 11 when there is water shortage, and the head of the water pump 9 will have a certain margin. Therefore, when water resources are more abundant, the water level in the water intake pipe well 11 will rise, and the actual water lifting head of the water pump 9 will become smaller, which will cause the head margin of the water intake pump to increase, thereby resulting in more energy waste and higher energy consumption.The groundwater pump house of the present invention is provided with the following structure: a floating platform 7 is also provided in the water replenishment chamber 2 and is vertically slidably connected to the water pump house body 1 so as to float up and down with the change of the water level in the water replenishment chamber 2; a water intake inner pipe 111 is fixedly installed in the water intake pipe well 11; a telescopic pipe 112 is inserted at the upper end of the water intake inner pipe 111, and the lower end of the telescopic pipe 112 is slidably and sealedly matched with the inner pipe 111 so as to be telescopic up and down; the upper end of the telescopic pipe 112 is connected to the water inlet of the water turbine generator 5; the water outlet of the water turbine generator 5 is connected to the water inlet of the water turbine generator 5 through the first branch pipe. 61 is connected to the water inlet end of the water outlet pipe 6, and the water inlet end of the water outlet pipe 6 is connected between the two ends of the water intake inner pipe 111 through the second branch pipe 62. The first branch pipe 61 and the second branch pipe 62 are respectively provided with an on-off control valve 63. Therefore, when the water resources are sufficient, as the water level of the river channel and the water levels in the water replenishment chamber 2 and the water intake pipe well 11 rise accordingly (the water replenishment chamber is connected to the river channel, the water replenishment chamber and the water intake pipe well are connected to each other through the water replenishment channel, and the water level lines of the river channel, the water replenishment chamber and the water intake pipe well are consistent), the floating The platform 7 floats (moves) upward accordingly under the buoyancy of the water. During the process of the floating platform 7 floating upward, the hydro-generator 5 is driven to move upward, so that the telescopic tube extends and becomes longer as the floating platform 7 floats upward. When the water intake pump 9 draws water, the on-off control valve 63 on the second branch pipe 62 can be closed, and the on-off control valve 63 on the first branch pipe 61 can be opened, so that the water flows through the water intake inner pipe 111, the telescopic tube, the hydro-generator 5 and the first branch pipe 61 and then flows into the water outlet pipe 6. In this way, the water kinetic energy generated by the excess lift of the water intake pump 9 can be used to drive the hydro-generator 5 to rotate. Power is generated, and the electric energy generated by the hydro-generator 5 is sent to the battery 3 for storage, which can be used by the water pump 9 to draw water, thereby reducing the amount of power supplied by the city electricity to the water pump 9, and reducing the energy consumption and operating costs of the pump room; when water resources are insufficient, the water level in the river channel and the water levels in the water replenishment chamber 2 and the water intake pipe well 11 drop to a certain level, the on-off control valve 63 on the second branch pipe 62 can be opened, and the on-off control valve 63 on the first branch pipe 61 can be closed, so that water flows out from the outlet pipe 6 after passing through the second branch pipe 62, so as to ensure that the water pump 9 can draw water.

[0033] In order to collect rainwater on the water intake pump house conveniently, the water intake pump house of the present invention is provided with a water collecting pipe for draining rainwater from the roof into the water replenishment chamber 2, so as to realize the mutual conversion of rainwater, surface water and groundwater.

[0034] The channel control of the on-off control valve 63 can be manually controlled by a person or automatically controlled by a controller. When the controller is automatically controlled, the controller controls the channel of the corresponding on-off control valve 63 according to the size of the water level parameter in the water replenishment chamber 2 detected by the sensor. For example, when the sensor detects that the water level parameter in the water replenishment chamber 2 is greater than the set value, the controller controls to close the on-off control valve 63 on the second branch pipe 62 and open the on-off control valve 63 on the first branch pipe 61; when the sensor detects that the water level parameter in the water replenishment chamber 2 is less than the set value, the on-off control valve 63 on the second branch pipe 62 is opened and the on-off control valve 63 on the first branch pipe 61 is closed.

[0035] like Figure 2 As shown, the present invention also provides a hollow float 8 in the water replenishment chamber 2 that can float up and down with the change of water level. The lower end of the float 8 located below the water surface is provided with a water inlet hole connected to its inner cavity. The bottom of the inner cavity of the float 8 is connected to the upper end of the water replenishment channel 12 through a drainage pipe 83 that can lengthen or shorten as the float 8 floats up and down. The drainage pipe 83 can adopt a bellows structure to achieve lengthening or shortening as the float 8 floats up and down. In some embodiments, the drainage pipe 83 also adopts a hose or telescopic pipe structure to achieve lengthening or shortening as the float 8 floats up and down. When river water replenishes groundwater, the river water first enters the float 8 through the water inlet hole of the float, and then enters the water replenishment channel 12 through the drainage pipe 83. The above structure uses a float 8 to inlet water, and the position of the float 8 can change with the change of the water level in the water replenishment chamber 2. The float 8 always floats on the water surface, so that the relatively clean river water above can be infiltrated to replenish the groundwater, which can increase the service life of the filter medium and improve the water quality of the pump room. The float can be made of a lightweight material that can float on the water surface.

[0036] In the embodiment of the present invention, Figure 2As shown, a water inlet pipe 81 connected to the water inlet hole is provided at one end outside the water inlet hole, and the other end (water inlet end) of the water inlet pipe 81 is lower than the connection end (water outlet end) of the water inlet pipe 81 and the water inlet hole, so that water can only flow upward along the water inlet pipe 81 into the float 8. The upper end of the float 8 located above the water surface is provided with an exhaust pipe 82 connected to its inner cavity, which is used to discharge the gas in the float 8 and facilitate water inlet. The exhaust pipe 82 is provided with an on-off control valve 63. In the figure, the water inlet pipe 81 is tilted downward to achieve that the height of the water inlet end of the water inlet pipe 81 is lower than the connection end of the water inlet pipe 81 and the water inlet hole. Generally, compared with river water that infiltrates through the water replenishment channel, groundwater that naturally infiltrates into the groundwater aquifer has better water quality. When the groundwater is sufficient, the above-mentioned structure can first lift the float 8 out of the water to discharge the water inside the float, and then close the on-off control valve 63 on the exhaust pipe 82 to prevent the gas in the float from being discharged through the exhaust pipe 82, thereby preventing water from entering the float. In this way, it is possible to prevent river water from infiltrating into the water intake pipe well 11, which is mainly groundwater, and can better ensure the quality of water intake.

[0037] In order to facilitate the inspection and maintenance of the equipment in the water pump room, a lighting system is provided in the water pump room. The lighting system may include lamps, which are powered by the mains. Figure 2 As shown, the lighting system includes a lighting device 17, a light guide fiber 18 and a projection light device 19. The lighting device 17 is arranged on the roof of the water intake pump room body 1, and is used to gather sunlight and couple it into the light guide fiber 18; one end of the light guide fiber 18 is connected to the lighting device 17, and the other end is connected to the projection light device 19, so as to transmit the light in the lighting device 17 to the projection light device 19; the projection light device 19 is installed in the water intake pump room body 1 to project light into the water intake pump room body 1. Compared with the use of lamps for lighting, the above lighting system is more energy-efficient and can further reduce the operating cost of the pump room. In the embodiment of the present invention, in order to facilitate the lighting device 17 to better gather sunlight, the lighting system also includes a sensor, a controller, a drive motor, etc. The lighting device 17 can be rotatably arranged on the roof of the water intake pump room body 1, so as to adjust its position accordingly according to the position of the sun. The sensor is used to sense the position of the sun, and the controller controls the action of the drive motor according to the position sensed by the sensor to rotate the lighting device 17 to a position relative to the sun.

[0038] like Figure 2As shown, the pump house is also provided with a second generator 21 and an impeller 22 arranged in the river channel 10 to rotate using the water force in the river channel. The second generator 21 is installed on the floating platform 7. The rotating shaft of the second generator 21 is drivingly connected to the impeller 22. The connecting terminal of the second generator 21 is electrically connected to the storage battery 3 to charge the storage battery 3. The above structure can use the water flow in the river channel to rotate the impeller 22 and rotate the second generator 21 to generate electricity. The electric energy generated by the second generator 21 is stored in the storage battery and can be used by the water pump, which can further reduce the demand for city electricity and the operating cost of the pump house.

[0039] In the present invention, the generator (hydraulic generator, second generator) and the battery are electrically connected to charge the battery 3 using the existing technology, and an AC / DC converter, a regulator and other equipment should be provided between them, which will not be described in detail.

[0040] In the embodiment of the present invention, a solar panel 20 is installed on the roof of the water intake pump house body 1, and the solar panel 20 is electrically connected to the battery 3 to charge the battery 3. The solar panel 20 is electrically connected to the battery 3 to charge the battery 3, which also adopts the existing technology, and the specific structure is not described again. The pump house of the present invention installs a solar panel 20 on the roof of the pump house, which can use solar energy to generate electricity, and the electricity generated by the solar panel 20 is stored in the battery 3, which can be used for the water intake pump, which can further reduce the demand for city electricity and the operating cost of the pump house.

[0041] In order to further ensure the water quality, a filtering device 14 is provided at the lower end of the water intake pipe well 11 , and a sand settling hole 15 is provided below the water intake pipe well 11 .

[0042] like Figure 2 As shown, the pump room is also provided with a backwash pipe 64 for backwashing the filter medium 13, one end of the backwash pipe 64 is connected to the outlet pipe 6, and the other end is connected to the water replenishment channel 12, and an on-off control valve 63 is provided on the backwash pipe 64. When the filter medium is blocked, the on-off control valve 63 on the backwash pipe 64 can be opened to allow the groundwater pumped out by the water pump to flow back into the water replenishment chamber from the backwash pipe water replenishment channel, thereby flushing out the blockage of the filter medium 13.

[0043] The filter medium in the present invention can adopt various existing filter media. In the embodiment of the present invention, the filter medium includes a reverse filter layer 131, a reverse filter layer 132 and a gravel layer 133, wherein the reverse filter layer 131 is arranged above the reverse filter layer 132 to facilitate backwashing, and the gravel layer 133 is arranged below the reverse filter layer 132. The above structure can ensure the stability of the filter medium.

[0044] In the embodiment of the present invention, the filter medium of the reverse filter layer 131 is polyethylene spherical shell + aldehyde vinylon silk bouquet or polypropylene wide flat ribbon, and the gravel layer 133 is gravel with a particle size of 7.5-10 mm. In the embodiment of the present invention, the reverse filter layer 132 is composed of four layers of filter medium.
