Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically to a submerged stainless steel self-coupling grid cover for a water inlet pipe. Background Technology
[0002] As a vital component of water resources, rivers not only bear the responsibility of maintaining ecological balance but also significantly contribute to the urban landscape. However, with increasing human activity, the problem of river waste has become increasingly serious, severely impacting the ecological environment and residents' lives.
[0003] River debris is diverse and complex, commonly including plastic products, paper waste, animal carcasses, trees, weeds or aquatic plants, and suspended solids. River debris not only affects the aesthetics of the environment, but in severe cases, it can clog pipes or impair the efficiency of pumps, disrupting water treatment processes and increasing production and maintenance costs for businesses.
[0004] Floating debris can be removed by retrieval or the installation of barriers, but suspended debris cannot be effectively treated using these methods. Installing a debris-blocking device at the water treatment inlet ensures the normal operation of subsequent water treatment structures; its importance as the first step in water treatment production is self-evident. While traditional debris-blocking devices can block aquatic organisms, debris, weeds, and household waste, they often become clogged after a period of use, potentially leading to accidents that compromise stable production operations. Therefore, for waste disposal in submerged pipelines, traditional submerged panel bar screens and rotary bar screens are insufficient to meet actual production needs, necessitating a more advanced submerged waste collection system. Utility Model Content
[0005] The purpose of this invention is to provide a submerged stainless steel self-coupling grid cover for water inlet pipes to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a submerged inlet pipe stainless steel self-coupling grid cover, comprising a stainless steel grid mesh installed at the outlet end of a sewage pipe, a semi-circular arc-shaped self-coupling groove connected to the outer top of the stainless steel grid mesh, a semi-circular arc-shaped slag collection groove connected to the inner bottom of the stainless steel grid mesh, a handle connected above the self-coupling groove via a stainless steel adjustable telescopic rod, and a positioner connected to the side of the handle.
[0007] Preferably, the stainless steel adjustable telescopic rod includes several stainless steel sleeves, with an adjusting pin hole at the end of each sleeve and an adjusting pin inside the adjusting pin hole.
[0008] The working process of this utility model is as follows:
[0009] The upper part of the stainless steel adjustable telescopic rod is positioned by a locator, and the lower part is connected to a submerged stainless steel grating and a slag collection trough via a self-coupling slot. Solid waste discharged from the sewage pipe is filtered by the stainless steel grating and collected in the slag collection trough. When a certain amount has accumulated, the solid waste in the slag collection trough is transferred and cleaned by lifting the handle, and then reconnected to the sewage pipe outlet. When it is necessary to adjust the insertion depth of the stainless steel grating, the adjusting pin holes of each sleeve of the stainless steel adjustable telescopic rod are changed, and then locked by a pin.
[0010] The beneficial effects of this utility model are as follows:
[0011] (1) In this utility model, the upper part of the stainless steel adjustable telescopic rod is positioned by a locator, and the lower part is connected to a submerged stainless steel grid and a slag collection trough by a self-coupling slot. The solid waste discharged from the sewage pipe is filtered by the stainless steel grid and collected in the slag collection trough. The stainless steel adjustable telescopic rod is connected by several sleeves to facilitate height adjustment. The stainless steel grid that extends deep into the bottom of the water effectively collects the fixed waste discharged from the sewage pipe at the bottom of the water, which is highly practical.
[0012] (2) This utility model is equipped with a telescopic rod and a positioner. The telescopic rod not only achieves the effect of saving effort and facilitating operation, but also allows for the adjustment of the position of the slag receiving trough at a certain angle. The positioner can control the adjustment operation to a certain extent, so that excessive force is not used during operation, which may cause excessive torque to the telescopic rod and damage it, thus ensuring the effectiveness of the equipment.
[0013] (3) The present invention connects a slag collection trough to the stainless steel grating to prevent garbage from floating randomly and accumulating to a certain extent to block the pipe and cause unnecessary production accidents. Attached Figure Description

[0015] In the diagram: 1. Self-coupling slot; 2. Stainless steel grating; 3. Slag receiving trough; 4. Stainless steel adjustable telescopic rod; 5. Adjusting pin hole; 6. Positioner; 7. Handle. Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] like Figure 1The illustration shows a submerged inlet pipe stainless steel self-coupling bar cover, comprising a stainless steel bar mesh 2 installed at the outlet end of the sewage pipe. A semi-circular arc-shaped self-coupling groove 1 is connected to the outer top of the stainless steel bar mesh 2, and a semi-circular arc-shaped slag collection groove 3 is connected to the inner bottom. A handle 7 is connected above the self-coupling groove 1 via a stainless steel adjustable telescopic rod 4, and a positioner 6 is connected to the side of the handle 7. The stainless steel adjustable telescopic rod 4 comprises several stainless steel sleeves, with adjusting pin holes 5 at the ends of the sleeves, and adjusting pins installed within the adjusting pin holes 5.
[0018] The working process of this utility model is as follows:
[0019] The upper part of the stainless steel adjustable telescopic rod 4 is positioned by the positioner 6, and the lower part is connected to the submerged stainless steel grating 2 and the slag collection tank 3 by the self-coupling slot 1. Solid waste discharged from the sewage pipe is filtered by the stainless steel grating 2 and collected in the slag collection tank 3. When a certain amount of solid waste is collected, it is transferred and cleaned by lifting the handle 7 and then reconnected to the sewage pipe outlet. When it is necessary to adjust the insertion depth of the stainless steel grating 2, the adjusting pin holes 5 of each sleeve of the stainless steel adjustable telescopic rod 4 are changed and then locked by the pin.
[0020] This utility model incorporates a telescopic rod and a positioner. The telescopic rod not only achieves labor-saving and convenient operation but also allows for angle adjustment of the slag receiving trough. The positioner provides control over the adjustment process, preventing excessive force that could damage the telescopic rod due to excessive torque, thus ensuring the equipment's effectiveness.
[0021] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, based on the technical teachings provided by this utility model and as common knowledge in the mechanical field, other equivalent modifications and improvements can be made, and these should also be considered within the scope of protection of this utility model.
