[0001] The utility model relates to the technical field of submersible pumps, in particular to a submersible pump that is convenient to install. Background Technique

[0002] A submersible pump is a pump used to pump liquid from deep water. It is usually used in fields such as drainage, irrigation, and sewage treatment. Submersible pumps are usually installed in water, so they need to have a waterproof design. Submersible pumps can use electricity or solar energy as the power source. They are usually composed of an electric motor, a pump body, an impeller, bearings, and seals, etc.

[0003] In the prior art, when a submersible pump is in use, the submersible pump is lowered to the bottom of the water for use, and the submersible pump needs to be installed at the bottom of the water to prevent it from shaking during operation. Generally, it is necessary for workers to go into the water to install it at the bottom. Each time the submersible pump is installed, it needs to be manually fixed, which will increase the usage threshold of the submersible pump and make the use of the submersible pump not simple enough.

[0004] The prior patent (publication number: CN220487886U) discloses a submersible pump that is convenient to install. By installing the base at the bottom of the water, and then lowering the submersible pump body to the base, and then making the limiting rod catch the position of the submersible pump body, the submersible pump body can be fixed at the bottom of the water, so that the installation of the submersible pump body does not require workers to go into the water for installation each time, making the use of the submersible pump body simple.

[0005] However, the above technical solution still has certain defects. The above device makes the submersible pump move downward along the connecting rope by passing through two connecting ropes and dock with the base for installation. However, the connecting rope is light in weight and easy to swing in water, resulting in the connecting rope not always being in a vertical state. At the same time, the outside of the above submersible pump lacks a protection structure, and some stones falling from the outside are easy to collide with the surface of the submersible pump, resulting in damage to the submersible pump. Therefore, a submersible pump that is convenient to install is proposed. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] A submersible pump that is convenient to install, as Figures 1 - 3 shown, includes a base main body 100. At the center of one side of the upper surface of the base main body 100, a fixed straight plate 110 is fixedly installed. A sliding groove is provided on the front side of the fixed straight plate 110, and a sliding plate 120 is slidably connected in the sliding groove. Two groups of balls 130 are rotatably connected to both sides of the sliding plate 120, and the two groups of balls 130 are slidably connected to the sliding groove. A submersible pump main body 140 is fixedly sleeved at one end of the sliding plate 120 away from the fixed straight plate 110. A clamping assembly 200 is provided in the base main body 100, and a protection assembly 300 is provided on the upper surface of the base main body 100 outside the submersible pump main body 140;

[0033] When the user installs the submersible pump main body 140, the sliding plate 120 is inserted into the sliding groove, and the submersible pump main body 140 descends vertically along the sliding groove through the sliding plate 120. By providing the balls 130, the friction between the sliding plate 120 and the sliding groove is reduced, making its descent smoother and more stable.

[0034] Please refer specifically to Figure 1 , Figure 5 , Figure 6 and Figure 7As shown in the figure, the protection component 300 includes a protection frame 310 fixedly installed on the upper surface of the base body 100 and located outside the submersible pump body 140. On both sides of the top of the protection frame 310, two sets of symmetrically arranged sliders 320 are slidably connected. The top of each set of sliders 320 is fixedly connected to the same moving cover plate 330. One side of a set of sliders 320 is fixedly connected to a first connecting rope 340. The other end of the first connecting rope 340 penetrates and extends outside the protection frame 310 and passes through a steering wheel 350 installed at the top of one side of the protection frame 310. The other end of the first connecting rope 340 is fixedly installed with a gravity ball 360. The other side of the slider 320 is fixedly connected to a second connecting rope 370. The other end of the second connecting rope 370 penetrates and extends into the protection frame 310 and passes through the steering wheel 350 and is fixedly connected to an L-shaped moving plate 380. Both ends of the outer side of the sliding plate 120 are fixedly connected to L-shaped pressing plates 3920. On both sides of the inner wall of the protection frame 310, second limiting grooves 3910 are opened. On the side of the L-shaped moving plate 380 close to the inner wall of the protection frame 310, a limiting block 390 matching the second limiting groove 3910 is fixedly installed. The L-shaped moving plate 380 is slidably connected to the second limiting groove 3910 through the limiting block 390. The mass of the gravity ball 360 is much larger than the mass of the L-shaped moving plate 380.

[0035] Since the mass of the gravity ball 360 is much larger than the mass of the L-shaped moving plate 380, the two moving cover plates 330 are pulled by the gravity ball 360, and the two moving cover plates 330 are in an open and closed state. When the submersible pump body 140 descends and moves, driving the L-shaped pressing plates 3920 fixed on both sides of the sliding plate 120 to move downward synchronously until the L-shaped pressing plates 3920 contact the L-shaped moving plate 380, a downward pressure is formed on the L-shaped moving plate 380, driving the L-shaped moving plate 380 to move downward together, thereby driving the second connecting rope 370 fixed to the top of the L-shaped moving plate 380 to move together. The slider 320 fixed to the other end of the second connecting rope 370 is pulled, thereby driving the moving cover plate 330 fixedly connected to the slider 320 to move towards the middle of the top of the protection frame 310 until the two moving cover plates 330 completely cover the top of the protection frame 310. Through the setting of the protection frame 310 and the moving cover plates 330, the submersible pump body 140 is protected, preventing some stones falling from the outside from colliding with the surface of the submersible pump and causing damage to the submersible pump.

[0036] Please refer specifically to Figure 1 As shown in the figure, a number of strip-shaped through grooves are provided on the protection frame 310.

[0037] Through the number of strip-shaped through grooves provided on the protection frame 310, the inside and outside of the protection frame 310 are connected, and it does not affect the water flow entering.

[0038] Please refer specifically to Figure 3 and Figure 4As shown in the figure, the clamping assembly 200 includes a snap ring 210 fixedly installed at the bottom of the submersible pump body 140. An annular slot 220 matching the snap ring 210 is formed on the upper surface of the base body 100. Limiting through holes are formed at corresponding positions on both sides of the snap ring 210 and the annular slot 220. An activity chamber is formed inside the base body 100, and motors 230 are fixedly installed on both side walls of the activity chamber. Threaded lead screws are fixedly connected to the output ends of the two groups of motors 230 through couplings. Threaded sleeves 240 are threadedly connected to the outside of each group of threaded lead screws. Limiting rods 250 are fixedly connected to both sides of the outer walls of the two groups of threaded sleeves 240. First limiting slots 260 matching the limiting rods 250 are formed on the front and rear side walls of the activity chamber. The end of each group of limiting rods 250 is slidably connected to the first limiting slot 260.

[0039] When the submersible pump body 140 slides down to the upper surface of the base body 100, the snap ring 210 is clamped with the annular slot 220. Subsequently, the two groups of motors 230 are started through an external controller. The output ends of the motors 230 drive the threaded lead screws to rotate, so that the two groups of threaded sleeves 240 move relatively along the direction of the first limiting slot 260 under the cooperation of the limiting rods 250 and the first limiting slots 260 until they are inserted into the limiting through holes, thereby realizing the underwater fixation of the submersible pump body 140 on the shore and making the use of the submersible pump body 140 more convenient.

[0040] During use, when the user installs the submersible pump body 140, the sliding plate 120 is inserted into the sliding groove. The submersible pump body 140 descends vertically along the sliding groove through the sliding plate 120. By providing the balls 130, the friction between the sliding plate 120 and the sliding groove is reduced, making its descent smoother and more stable. Since the mass of the gravity ball 360 is much larger than the mass of the L-shaped moving plate 380, the two groups of moving covers 330 are pulled by the gravity ball 360 and the two groups of moving covers 330 are in an open and closed state. When the submersible pump body 140 descends and drives the L-shaped pressing plates 3920 fixed on both sides of the sliding plate 120 to move downward synchronously until the L-shaped pressing plates 3920 contact the L-shaped moving plate 380, a downward pressure is formed on the L-shaped moving plate 380, driving the L-shaped moving plate 380 to move downward together, thereby driving the second connecting rope 370 fixed to the top of the L-shaped moving plate 380 to move together. The slider 320 fixed to the other end of the second connecting rope 370 is pulled, thereby driving the moving cover 330 fixedly connected to the slider 320 to move towards the middle of the top of the protection frame 310 until the two groups of moving covers 330 completely cover the top of the protection frame 310. Through the settings of the protection frame 310 and the moving covers 330, the submersible pump body 140 is protected, preventing some falling stones from colliding with the surface of the submersible pump and causing damage to the submersible pump. The parts not involved in this device are the same as or can be implemented using the prior art.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
