Submersible pump silt prevention device for river pond

Abstract

A placement angle adjusting mechanism comprises a mounting plate, a driving threaded rod, an internal thread rotating sleeve, a driving frame plate and a supporting bent rod, the middle end of the mounting plate is rotationally connected with the driving threaded rod, and the upper end of the driving threaded rod is in threaded connection with the internal thread rotating sleeve; the right end of the internal thread rotating sleeve is rotationally connected with a driving frame plate, the front end and the rear end of the driving frame plate are rotationally connected with supporting bent rods, the left ends of the supporting bent rods are rotationally connected to the upper end of the mounting plate, and the left end of the driving frame plate is rotationally connected with a sliding sleeve. When the internal thread rotating sleeve moves upwards, the internal thread rotating sleeve drives the left end of the driving frame plate to move upwards, the right end of the driving frame plate is supported to be flush with the left end through the supporting bent rod, at the moment, the driving frame plate is converted into a transverse flat state from a vertical state, and a water inlet in the bottom end of the submersible pump is lifted.

Description

technical field [0001] The invention relates to the field of submersible pumps, in particular to a sediment prevention device for submersible pumps used in rivers and ponds. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water and extracts groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. [0003] When existing submersible pumps are used to pump water in ponds or rivers, water plants and sediment are easily adsorbed at the water inlet, which requires staff to take the submersible pump out of the river or pond for cleaning, and cannot automatically clean the water at the water inlet of the submersible pump. Removal of aquatic plants and sediment will lead to a decline in the pumping function of the submersible pump and increase the working intensity. When the...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, a kind of anti-sediment device for submersible pumps for rivers and ponds is provided. This technical solution solves the problem that the existing submersible pumps proposed in the above background technology are easy to absorb aquatic plants when pumping water in ponds or rivers. With sediment, it is necessary for the staff to take the submersible pump out of the river or pond for cleaning. It is impossible to automatically remove the water plants and sediment at the water inlet of the submersible pump when pumping water, which leads to the decline of the pumping function of the submersible pump and increases the work intensity. And when the existing submersible pump pumps water, the submersible pump usually lies flat on the bottom of the river or pond, and the posture of the submersible pump at the bottom of the water cannot be adjusted. Problems that occur when sediment enters the water inlet of the submersible pump and is blocked by aquatic plants
