Description

Technical Field

[0001] This utility model relates to the field of groundwater extraction technology, specifically to a high-efficiency and energy-saving groundwater extraction well pipe filtration and protection device. Background Technology

[0002] Groundwater, as a vital water resource, plays a crucial role in industrial production, residential life, and agricultural irrigation. In groundwater extraction operations, well pipes serve as the key channels for drawing groundwater, and the water quality inside them is complex. Typically, the water extracted from well pipes contains a large amount of sand, gravel, and other impurities, requiring the use of filtration devices to prevent these impurities from harming equipment or users.

[0003] Based on the above, the inventors have discovered the following problems: When the extracted groundwater enters the filtration and protection device for filtration, the sediment in the water is effectively intercepted by the filter screen as it flows through the screen. Once the sediment is blocked by the filter screen, it is very easy for it to accumulate on the surface of the filter screen and in the surrounding area. As the groundwater usage time continues to increase, the amount of sediment accumulation continues to rise, which not only hinders the speed of water flow through the filter screen, causing a significant reduction in filtration efficiency, but also puts continuous pressure on the filter screen, accelerating its damage and greatly shortening its service life.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a high-efficiency and energy-saving groundwater extraction well pipe filtration and protection device, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency and energy-saving groundwater extraction well pipe filtration and protection device to solve the problem mentioned in the background art that the existing filtration and protection devices lack a sediment discharge device, and sediment easily accumulates inside the filtration and protection device.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A high-efficiency and energy-saving groundwater extraction well pipe filtration and protection device includes a support mechanism, a filtration mechanism, and an auxiliary mechanism. The support mechanism includes a base and a screw pump, with the input end of the screw pump connected to the bottom end of the base. The filtration mechanism includes a protective cylinder, the bottom end of which is threadedly connected to the upper end of the base. A filter cartridge is installed inside the protective cylinder, and a filter cavity is formed between the inner side wall of the protective cylinder and the outer side wall of the filter cartridge. A mounting bracket is fixedly installed at the bottom end of the filter cartridge. A rotating shaft is rotatably connected between the center of the upper end face of the mounting bracket and the center of the top end of the filter cartridge. A scraper is installed on one side of the rotating shaft, and one side of the scraper abuts against the inner wall of the filter cartridge. The auxiliary mechanism includes a flexible solar panel, which is sleeved on the outside of the bottom end of the protective cylinder.

[0008] The filter cartridge has several filter holes circumferentially arranged on its outer side along its axis, through which groundwater enters the filter cavity.

[0009] Furthermore, the filtration mechanism also includes a pre-filter layer, a medium-efficiency filter layer, and a high-efficiency filter layer. The pre-filter layer is sleeved on the outside of the filter cartridge, the medium-efficiency filter layer is sleeved on the outside of the pre-filter layer, and the high-efficiency filter layer is sleeved on the outside of the medium-efficiency filter layer. The pre-filter layer, the medium-efficiency filter layer, and the high-efficiency filter layer are all located inside the filter cavity.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the pre-filter layer, medium-efficiency filter layer, and high-efficiency filter layer in the filtration mechanism are sequentially nested on the outside of the filter cartridge and located inside the filter cavity. This multi-layer filtration structure can perform multi-stage filtration of groundwater, gradually removing impurities of different particle sizes and properties, thereby improving filtration efficiency and water quality. Furthermore, the pre-filter layer is made of non-woven fabric, the medium-efficiency filter layer is made of glass fiber, and the high-efficiency filter layer is made of activated carbon fiber.

[0011] The beneficial effects of adopting the above-mentioned further solutions are that the primary filter layer is made of non-woven fabric, which can effectively intercept larger particles of impurities and, together with the filter holes on the filter cartridge, plays a preliminary filtration role. The secondary filter layer is made of glass fiber, which can further filter smaller particles and improve filtration accuracy. The high-efficiency filter layer is made of activated carbon fiber, which can adsorb organic matter, odors, heavy metals and other harmful substances in the water and improve the purity of the water.

[0012] Furthermore, a servo motor is fixedly installed at the upper end of the protective cylinder, and the output end of the servo motor is connected to the rotating shaft for transmission.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the servo motor at the upper end of the protective cylinder is connected to the rotating shaft, and the servo motor can drive the rotating shaft to rotate, thereby driving the scraper to scrape off the impurities on the inner wall of the filter cylinder, maintaining the filtration performance of the filter cylinder, and improving the cleaning effect of mud and sand.

[0014] Furthermore, a drain pipe is inserted into one side of the upper end of the protective cylinder, and one end of the drain pipe is connected to the filter cavity.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the drainage pipe on one side of the upper end of the protective cylinder is connected to the filter chamber, and the groundwater after multi-stage filtration can be discharged from the device through the drainage pipe, thereby realizing the extraction and transportation of groundwater.

[0016] Furthermore, the auxiliary mechanism also includes a power distribution box, one side of which is connected to the upper side of the protective cylinder. A storage battery is fixedly installed at the bottom of the power distribution box, and a charging controller is fixedly installed at the upper end of the storage battery. The storage battery is electrically connected to the charging controller, servo motor, flexible solar panel and screw pump through wires.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the battery in the distribution box of the auxiliary mechanism is electrically connected to the charging controller, servo motor, flexible solar panel and screw pump. The flexible solar panel converts solar energy into electrical energy, which is used to charge the battery through the charging controller. The battery supplies power to the servo motor and screw pump, thereby achieving the purpose of energy saving through auxiliary power supply.

[0018] Furthermore, a number of support legs are fixedly installed on the outer side of the bottom end of the base, and the number of support legs are distributed circumferentially along the axis of the base. A water inlet pipe is inserted into the bottom side of the base.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the support legs on the outer side of the bottom end of the base are distributed circumferentially along the axis of the base, providing stable support for the device and ensuring the stability of the device during operation. The water inlet pipe on the bottom side of the base is used to introduce groundwater so that the groundwater can enter the filter cartridge for filtration.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-efficiency and energy-saving groundwater extraction well pipe filtration and protection device has a base supporting the entire device. The screw pump can be used to discharge the silt inside the filter cylinder. The protective cylinder of the filtration mechanism is threadedly connected to the base, which is convenient for installation and disassembly. The filter cylinder inside the protective cylinder and the inner wall of the protective cylinder form a filter cavity. Groundwater enters the filter cavity through the filter holes on the filter cylinder to achieve preliminary filtration. The scraper on the rotating shaft abuts against the inner wall of the filter cylinder and can scrape off the impurities on the inner wall of the filter cylinder when rotating. At the same time as the scraper rotates, it can drive the water inside the filter cylinder to rotate, thereby flushing the filter holes and preventing silt from accumulating in the filter holes and causing blockage. When the device is not in use, the silt in the filter cylinder is deposited at the bottom of the base due to its own weight. The silt can be transported out by starting the screw pump. By cleaning and discharging the silt inside the filter cylinder, the filtration efficiency of the device is improved. The flexible solar panel of the auxiliary mechanism is sleeved on the outside of the bottom of the protective cylinder and can convert solar energy into electrical energy to provide energy for the device, thus achieving energy saving.
