By arranging the adjusting air bag and the limiting frame, when water is taken, the driving fan blades can be driven to rotate through flowing of water flow, so that the filter screen frame rotates, in this way, in cooperation with the cambered surface of the filter screen frame, falling of adsorbates on the outer side of the filter screen frame can be facilitated, and the adhesion amount of impurities on the outer side of the filter screen frame is reduced; through sliding of the limiting frame and the first sliding groove, when a large object collides, the filter screen frame can move upwards, meanwhile, adsorption of the large object can be avoided through matched selection, in this way, the change amplitude of the water inflow is small, therefore, large changes of pressure and flow in the water suction pump and the valve are avoided, and the possibility of cavitation is reduced.

Description

Technical Field

[0001] The invention relates to the technical field of water intake pump boats, in particular to a water intake pump boat with a new structure. Background Art

[0002] Floating boat water intake refers to the water intake of a floating boat placed in a body of water from a river, lake or reservoir. Water intake equipment is installed in the cabin and connected to the water pipe on the shore by a connecting pipe. According to the power of the ship, there are two types: self-propelled and non-self-propelled (moored). The self-propelled type is a motor vessel, and the cabin is equipped with an internal combustion engine-linked water pump unit and self-propelled power equipment. There are also cases where the power device of the water intake equipment is used as a self-propelled power. It can adapt to the swing of the mainstream of the river, so it is mostly used to take water in wandering river sections. The non-self-propelled (moored) type is not equipped with a self-propelled power device and is more widely used than the self-propelled type.

[0003] In the prior art, when a water pump boat is in use, impurities in the water body are likely to enter the water inlet pipe, and the impurities are likely to affect the use of the water pump. Therefore, a filtering device needs to be installed at the water inlet pipe. In actual use, the filtering device is mostly directly fixedly connected to the pipe. The strong suction force when the water flows will cause impurities to adhere to the surface of the filtering device, thereby causing the filtering device to be blocked and the water intake to be affected. At this time, the amount of water entering the water pump is reduced, causing the water flow and pressure in the water pump and valve to change, and cavitation is likely to occur, affecting the service life of the water pump and the valve. Summary of the invention

[0004] The purpose of the present invention is to provide a water intake pump boat of a new structure to solve the problem proposed in the above background technology that when the water intake pump boat is in use, impurities in the water body are likely to enter the water inlet pipe, and the impurities are likely to affect the use of the water pump. Therefore, a filtering device needs to be installed at the water inlet pipe. In actual use, the filtering device is mostly directly fixedly connected to the pipe. The strong suction force when the water flows will cause impurities to adhere to the surface of the filtering device, thereby causing the filtering device to be blocked and the water intake to be affected. At this time, the amount of water entering the water pump is reduced, causing the water flow and pressure in the water pump and valve to change, and cavitation is likely to occur, affecting the service life of the water pump and the valve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, by adjusting the settings of the air bag and the limit frame, when taking water, the flow of water can drive the driving blades to rotate, thereby causing the filter frame to rotate. In this way, in conjunction with the curved surface of the filter frame, it is easy to remove the adsorbed objects on the outside of the filter frame, and the amount of impurities attached to the outside of the filter frame is reduced. By sliding the limit frame and the No. 1 slide groove, when a larger object collides, the filter frame can be moved upward. At the same time, the selection can avoid the adsorption of larger objects. In this way, the water intake volume changes less, thereby avoiding large changes in pressure and flow in the water pump and the valve, reducing the possibility of cavitation and increasing the service life. By adjusting the setting of the air bag, the buoyancy is used to pull the filter frame, so that the force required to move the filter frame upward is reduced, which is convenient for use.

[0017] 2. In the present invention, the limit frame is used in a manner of cooperating between a cylinder and a sphere, which has little effect on the water flow. At the same time, the actual contact surface with the No. 1 slide groove is small, so as to ensure the normal rotation of the driving fan blades and the up and down movement of the filter frame. The side wing plates are arranged to facilitate the installation and use between the filter frame and the water suction pipe, making the installation more convenient and easy to disassemble for maintenance. At the same time, with the rotatable design of the filter frame, when repairing, only the filter frame needs to be moved to move the bolts to the side facing the maintenance personnel for easy disassembly and installation.

[0018] 3. In the present invention, the inner support plate is provided to limit the filter mesh frame, so that the filter mesh frame can move together when the filter mesh frame moves up and down, thereby ensuring that the surface of the filter mesh frame can be cleaned at any position. The arc surface on the outer side of the inner support plate has a smaller contact surface with the filter mesh frame, thereby reducing the friction between the filter mesh frame and the filter mesh frame, thereby reducing the impact caused by the rotation of the filter mesh frame and ensuring the normal rotation of the filter mesh frame.

[0019] 4. In the present invention, the protective airbag is provided to protect the side of the hull when approaching the shore to avoid leakage of the hull caused by collision, thereby ensuring safety in use. The No. 3 slide slot and the connecting frame are arranged in coordination, and a detachable design is adopted to facilitate replacement and maintenance. The setting of the limit rod facilitates the installation limitation between the mounting frame and the connecting frame, which is convenient for use. The setting of the impeller adopts a combination of long and short blades to increase the outlet width, so that the liquid flow can flow more smoothly near the impeller, reducing the rapid acceleration and pressure reduction of the liquid flow, thereby reducing the possibility of cavitation.
