Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, and more specifically, to a sewage pump with a protective structure. Background Technology

[0002] A sewage pump is a type of pump specifically designed for conveying sewage or wastewater containing impurities such as solid particles, fibers, and suspended solids. Unlike ordinary water pumps that convey clean water, its core design goals are anti-clogging, corrosion resistance, and adaptability to complex media. It is widely used in sewage treatment, drainage engineering, and other fields.

[0003] A search revealed Chinese patent application CN214617178U, which discloses an anti-clogging sewage pump with a protective structure, relating to the field of sewage pump technology. The pump includes a main body, a filter plate welded to the input end, and four connecting blocks welded to the bottom of the main body. A main buffer pad is fixedly connected to the bottom of each connecting block, and a buffer column is welded to the bottom of each connecting block. During use, the counterweight ring adjusts the grounding point of the equipment during descent to ensure contact with the bottom of the water using the support pad. After two buffering cycles by water and the support pad, the impact and pressure of the falling equipment cause the connecting blocks to move the buffer column towards the buffer arm within the buffer chamber. The reduced gap between the buffer column and the buffer arm on opposite sides allows the pressure to be absorbed by the buffer spring, thus reducing the pressure on the main body and support structure of the sewage pump and preventing the support structure from being entirely absorbed by the material, which would lead to accelerated wear and tear. While the aforementioned patent can improve equipment stability, it still has the following shortcomings during use: The patent has four buffer arms to improve stability, but the buffer arms are connected to a counterweight ring and a support pad. If the mounting surface is slightly tilted or uneven, the buffer arms cannot adjust themselves, and the stabilizer may become suspended or partially overloaded, causing the pump body to tilt and affecting the pump's stability. Utility Model Content

[0004] The purpose of this invention is to provide a sewage pump with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A sewage pump with a protective structure includes: a main motor; Pump body fixedly connected to the bottom of the main motor; A protective assembly is fixedly connected between the main motor and the outer wall of the pump body; the protective assembly includes a stabilizing mechanism fixedly connected between the main motor and the outer wall of the pump body, and the stabilizing mechanism is connected to an anti-collision mechanism.

[0006] As a preferred technical solution of this application, the stabilizing mechanism includes a lower mounting bracket fixedly connected to the outer wall of the bottom end of the main motor. A T-shaped rod is fixedly connected to the bottom of the lower mounting bracket. An adjusting block is sleeved on the outer wall of the T-shaped rod. A stabilizing rod is fixedly connected to the bottom of the outer end of the adjusting block. A stabilizing seat is fixedly connected to the bottom of the stabilizing rod. An adjusting spring is fixedly connected to the bottom of the adjusting block. The end of the adjusting spring away from the adjusting block is fixedly connected to the top surface of the bottom end of the T-shaped rod. A guide block is fixedly connected to one side of the adjusting block. The outer surface of the guide block is slidably connected to the inner surface of the guide groove, which is located on one side of the connecting rod. The top of the connecting rod is fixedly connected to the bottom of the arc-shaped rod. The two sides of the arc-shaped rod are respectively fixedly connected to the two sides of the inner surface of the lower mounting bracket.

[0007] As a preferred technical solution of this application, the anti-collision mechanism includes a reinforcing rib fixedly connected to the top of the adjusting block. The top end of the reinforcing rib passes through the bottom of the protruding end of the lower mounting frame and extends through the bottom of the protruding end of the upper mounting frame. The inner wall of the upper mounting frame is fixedly connected to the top outer wall of the main motor. An outer edge rod is fixedly connected to the inner surface of the upper mounting frame, and an anti-collision rod is threaded through the bottom of the outer edge rod.

[0008] As a preferred technical solution of this application, the inner wall of the inner end of the adjusting block and the outer wall of the T-shaped rod are configured to slide together, so that the adjusting block can drive the stabilizing seat to adjust its height through the stabilizing rod, and the stabilizing seat can be automatically adjusted according to the ground conditions.

[0009] As a preferred technical solution of this application, the number of the stabilizing seats is set to six, and the six stabilizing seats are respectively fixedly connected to the bottom of the six stabilizing rods. The six stabilizing seats make the pump body bear the force evenly and avoid the center of gravity shift caused by too few support points.

[0010] As a preferred technical solution of this application, the reinforcing ribs are arranged in groups of four, and the top of each group of reinforcing ribs is slidably connected to the protruding ends of the lower mounting frame and the upper mounting frame. While protecting the device, the reinforcing ribs can move synchronously with the adjusting block, thus limiting the movement of the adjusting block.

[0011] As a preferred technical solution of this application, the upper and lower ends of the anti-collision bar are threaded through the upper and lower outer edge bars respectively, and the two sides of the lower outer edge bar are fixedly connected to the inner surface of the lower mounting bracket respectively. The anti-collision bar can be rotated to adjust the extension length by threading through the upper and lower outer edge bars, and it is convenient to replace the anti-collision bar.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the stabilizing mechanism, when the contact surface is uneven or the pump body is impacted, the adjusting block automatically adjusts its position by compressing or stretching the adjusting spring and slides up and down on the outer wall of the T-shaped rod. The adjusting block drives the stabilizing seat to move up and down through the stabilizing rod, so that the six stabilizing seats automatically adjust their respective heights according to the contact surface conditions and always fit the support surface, thereby avoiding the instability of the pump body from affecting normal operation. 2. The anti-collision mechanism forms a ring-shaped protective ring with the upper mounting bracket and the outer edge rod, covering the outside of the motor and directly withstanding external collisions. The anti-collision rod is threaded through the upper and lower outer edge rods, making it easy to disassemble and replace. When an external collision occurs, the anti-collision rod directly bears the impact force, which is then transmitted to the stabilizing mechanism through the reinforcing ribs and distributed to the entire pump body, preventing damage to the main motor and pump body.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0016] like Figure 1-4 As shown, the sewage pump with a protective structure proposed in this embodiment includes: a main motor 1; Pump body 2 is fixedly connected to the bottom of main motor 1; A protective component 3 is fixedly connected between the main motor 1 and the outer wall of the pump body 2; the protective component 3 includes a stabilizing mechanism 31 fixedly connected between the main motor 1 and the outer wall of the pump body 2, and the stabilizing mechanism 31 is connected to an anti-collision mechanism 32.

[0017] in, like Figure 1 and Figure 2 As shown, the stabilizing mechanism 31 includes a lower mounting bracket 311 fixedly connected to the outer wall of the bottom end of the main motor 1. A T-shaped rod 312 is fixedly connected to the bottom of the lower mounting bracket 311. An adjusting block 313 is sleeved on the outer wall of the T-shaped rod 312. A stabilizing rod 314 is fixedly connected to the bottom of the outer end of the adjusting block 313. A stabilizing seat 315 is fixedly connected to the bottom of the stabilizing rod 314. An adjusting spring 316 is fixedly connected to the bottom of the adjusting block 313. One end of the adjusting spring 316 away from the adjusting block 313 is fixedly connected to the top surface of the bottom end of the T-shaped rod 312. A guide block 317 is fixedly connected to one side of the adjusting block 313. The outer surface of the guide block 317 is slidably connected to the inner surface of the guide groove 319. The guide groove 319 is opened on one side of the connecting rod 318. The top of the connecting rod 318 is fixedly connected to the bottom of the arc-shaped rod 310. The two sides of the arc-shaped rod 310 are respectively fixedly connected to the two sides of the inner surface of the lower mounting bracket 311.

[0018] To further explain, the inner wall of the inner end of the adjusting block 313 and the outer wall of the T-shaped rod 312 are configured to slide together, so that the adjusting block 313 can drive the stabilizing seat 315 to adjust its height through the stabilizing rod 314, so that the stabilizing seat 315 can be automatically adjusted according to the ground conditions.

[0019] The preferred number of stabilizers 315 is six. The six stabilizers 315 are fixedly connected to the bottom of the six stabilizers 314 respectively. The six stabilizers 315 make the pump body 2 evenly stressed and avoid the center of gravity shift caused by too few support points.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the anti-collision mechanism 32 includes a reinforcing rib 321 fixedly connected to the top of the adjusting block 313. The top end of the reinforcing rib 321 passes through the bottom of the protruding end of the lower mounting bracket 311 and extends through the bottom of the protruding end of the upper mounting bracket 322. The inner wall of the upper mounting bracket 322 is fixedly connected to the top outer wall of the main motor 1. An outer edge rod 323 is fixedly connected to the inner surface of the upper mounting bracket 322. An anti-collision rod 324 is threaded through the bottom of the outer edge rod 323.

[0021] The preferred reinforcing ribs 321 are arranged in groups of four. The top of each group of reinforcing ribs 321 is slidably connected to the protruding ends of the lower mounting bracket 311 and the upper mounting bracket 322. While protecting the device, the reinforcing ribs 321 can move synchronously with the adjusting block 313, thus limiting the movement of the adjusting block 313. The upper and lower ends of the anti-collision bar 324 are threaded through the upper and lower outer edge bars 323, respectively. The two sides of the lower outer edge bar 323 are fixedly connected to the inner surface of the lower mounting bracket 311. The anti-collision bar 324 can be rotated to adjust its extension length and is easy to replace by threading through the upper and lower outer edge bars 323.

[0022] When this sewage pump with a protective structure is in use: when the pump body 2 is impacted or the mounting surface is uneven, the adjusting block 313 automatically adjusts its position through compression or tension springs, sliding up and down on the outer wall of the T-shaped rod 312. Simultaneously, the adjusting block 313 drives the guide block 317 to slide within the guide groove 319, thus guiding the movement of the adjusting block 313. At the same time, the adjusting block 313 drives the stabilizing seat 315 to move up and down through the stabilizing rod 314, ensuring that the stabilizing seat 315 always fits against the support surface, avoiding local stress concentration. Meanwhile, the six stabilizing seats 315 are evenly distributed around the pump body 2, forming a hexagonal stable structure with a larger contact area and more stable support, preventing the pump body 2 from tilting or tipping over. They can also flexibly adjust their height according to the situation when the pump body 2 is impacted or the mounting surface is uneven, further improving the stability of the pump body 2.

[0023] When an external collision occurs, the upper mounting bracket 321 and the outer edge rod 323 form an annular protective ring, covering the outside of the main motor 1. At the same time, the anti-collision rod 324 directly bears the impact force and transmits it to the stabilizing mechanism 31 through the reinforcing rib 321, dispersing it to the entire pump body 2, thereby preventing damage to the main motor 1 and the pump body 2. Meanwhile, the anti-collision rod 324 is threaded through the upper and lower outer edge rods 323, making it easy to disassemble and replace.

[0024] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
