Detailed Description
In order to better understand the utility model discloses, it is right below with concrete embodiment and the attached drawing the utility model discloses carry out further description, as shown in fig. 1-3, a water shortage protection device for water pump, including protection device body 1, water inlet 2 and delivery port 3 have been seted up to protection device body 1 both sides, 2 one sides of water inlet are installed the water inlet 2 and are linked together with the water source of filtration device, and the delivery port 3 of the device is connected with the water inlet of water pump.
The filtering structure comprises a filtering net 4 arranged on the water inlet 2, a filtering box body 5 fixedly arranged on the water inlet 2, and a dust removal assembly 6 arranged at the top of the filtering box body 5. The dust removal component 6 is including fixing filter box 5 inside threaded rod 7, threaded rod 7 is connected with small motor 8, threaded rod 7 with filter box 5 rotates to be connected, threaded rod 7 and 9 threaded connection of slider, fixed mounting has dust removal scraper blade 10 on the slider 9. Get into the aquatic in the water shortage protection device often contains a large amount of graininess impurity, filters through filtration before getting into the water pump, and the impurity in the water source through filtering the box 5 is intercepted on the filter screen surface to operating personnel can carry out regular clearance, and driving threaded rod 7 rotates after small motor 8 starts, and slider 9 removes on threaded rod 7 when threaded rod 7 rotates, and dust removal scraper blade 10 removes along with the removal of slider 9.
The dust removal scraper 10 is composed of a first scraper 11 and a second scraper 12 which are integrally formed and perpendicular to each other, and the first scraper 11 abuts against the filter screen 4 and slides along the filter screen 4. The side wall of the filtering box body 5 is provided with a sealing door 13, and a sealing ring is arranged between the sealing door 13 and the filtering box body 5. The first scraper blade 11 contacts with the filter screen 4 to scrape the granular impurities on the filter screen 4 to the corners of the filter box body 5, and after the dust removal process is finished, the first scraper blade 11, the second scraper blade 12, the filter box body 5 and the sealing door 13 form a closed space to collect the granular impurities. This causes the impurities, which have been cleaned up during the circulation of the subsequent water source, to be attached to the filter net 4 again to cause clogging. After a certain period of time, the impurities can be completely removed by opening the sealing door 13.
The protection device comprises a protection device body 1, wherein a controller is fixed outside the protection device body 1, the protection device body 1 comprises an upper shell 14 and a lower shell 15, a spring 16 is arranged inside the upper shell 14, a spring seat 17 for accommodating the spring 16 is arranged at the top of the upper shell 14, the bottom of the spring 16 is fixedly connected with a pressure diaphragm 18, and the pressure diaphragm 18 is fixedly connected with a guide post 19.
