An anti-floating fire pumping station with rainwater collection function, including: a pump box, a water storage tank, the water storage tank is buried underground, and the water storage tank is set on the ground for collecting rainwater. When filling water, turn on the lifting motor, the lifting motor drives the first turning circle to rotate, the first turning circle then drives the driving drum and the second turning circle to rotate together, the driving gear ring on the second turning circle meshes with the teeth on the outside of the lifting ring to make the lifting ring rotate , when the lifting ring rotates, due to the action of the thread, the overall movement of the guide tube and the filter bucket moves along the axis of the guide tube. When the upper port of the filter bucket moves below the water surface in the reservoir, the water stored in the reservoir will be filtered The bucket enters the diversion pipe, and then flows into the interior of the water storage tank from the lower end of the diversion pipe, thereby realizing the utilization of rainwater stored in the reservoir and saving water resources.

The invention discloses a spiral flow self-discharging sand filter tank, which relates to the technical field of agricultural irrigation. It includes a grit chamber, a clear water tank is provided at the end of the grit chamber, a water inlet gate is provided at the front end of the grit chamber, and an outlet gate is provided at the rear end of the clean water pond. A first notch is provided on the wall body between, and a plurality of overflow grooves are provided on the bottom surface of the first notch. The flow regulating plate in the grit chamber divides the inner space of the grit chamber into a steady flow section and a sand settling section. The bottom of the desilting section is provided with at least two desilting vortex tubes, one end of the desilting volute extends through the side wall of the desilting tank to the outside of the desilting tank, and is located at the A second notch is arranged on the sand discharge vortex tube inside the pool. The sand settling filter pool can achieve the double effect of sand settling and filtering within the shortest effective length, greatly improves the sand settling efficiency, and meets the requirement that surface water enter ditches and ditches for irrigation.

The invention relates to the technical field of oil field exploitation, and discloses an oil well pump used in an oil field, which includes an oil well, a pump barrel and an oil inlet chamber, the pump barrel is fixedly socketed with the oil well, and the top end of the oil inlet chamber is connected to the bottom of the pump barrel. End fixed connection. Through the setting of the spiral scraper, the spiral scraper can remove the crude oil adhering to the inner wall of the pump barrel under the plunger, reduce the thickness of the adhered crude oil, so as to better form an oil film and reduce the crude oil adhering to the inner wall of the pump barrel The sand inside can reduce the accumulation of sand between the plunger and the pump barrel, reduce the wear of the plunger, and increase the service life of the oil well pump. At the same time, through the setting of the central shaft and the cross rod, as the plunger descends, the screw The scraper is rotated by the upward impact of the crude oil, and then drives the middle sealing ball to rotate, so that the crude oil forms a swirling flow and transmits upwards, reduces the resistance to the plunger, speeds up the transmission rate, and reduces the direct impact with the middle sealing ball, further accelerating the crude oil. transmission rate.
