Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a detachable filter assembly for preventing blockage in water conservancy pipelines. Background Technology

[0002] In the field of water conservancy engineering, water pipelines, as the core infrastructure for water resource transportation and allocation, are widely used in various scenarios such as agricultural irrigation, urban water supply, drainage, and flood control. However, in actual operation, the water flow in water pipelines often carries a large amount of solid impurities, such as sand, silt, and plant debris from natural water bodies, as well as debris from aging pipelines and external foreign matter. If these impurities accumulate directly in the pipeline, they can easily cause pipeline blockage, which will not only lead to a decrease in water flow and reduced transportation efficiency, resulting in water waste and increased energy consumption, but may also cause pipeline rupture and leakage due to abnormal increases in local pressure, thereby causing safety hazards such as floods and water supply interruptions, seriously affecting the stable operation of water conservancy projects.

[0003] To address pipe blockage issues, existing technologies typically incorporate filtration devices into water pipeline systems, using filters and other structures to intercept impurities in the water flow. However, traditional filtration devices suffer from several drawbacks: Firstly, filters are often installed horizontally or vertically, allowing water to directly impact their surface, causing impurities to accumulate rapidly and clog the filter pores. This necessitates frequent shutdowns for cleaning, resulting in high maintenance costs and disruptions to water supply continuity. Secondly, traditional filtration devices often feature integrated filter housings, making it difficult to disassemble the filter and internal components. Cleaning impurities requires extensive pipe disassembly, which is cumbersome, time-consuming, and prone to damaging components during the process. Utility Model Content

[0004] This utility model relates to a detachable anti-clogging filter component for water conservancy pipelines, which solves the problems of traditional water conservancy pipeline filter devices, such as filter screens being easily clogged by impurities due to water flow impact and components being difficult to disassemble, leading to cumbersome maintenance.

[0005] This utility model provides a detachable anti-clogging filter assembly for water conservancy pipelines, specifically including: a filter housing, a filter groove on the top surface of the filter housing, and a round-and-square pipe connected to the filter groove fixedly installed on the upper side of the left and right end surfaces of the filter housing; a limiting slot is provided on the front, rear, and right sides of the inner end of the filter groove, and the limiting slot penetrates the top surface of the filter housing; the limiting slot is inclined, forming a 25-degree angle with the right side of the inner end of the filter groove, and the bottom of the limiting slot is lower than the connection between the round-and-square pipe and the filter groove; a barrier plate is inserted into the limiting slot, and a filter screen is embedded in the left and right ends of the barrier plate; the bottom surface of the inner end of the filter groove is inclined with the left side lower and the right side higher, and the bottom surface of the inner end of the filter groove has a semi-circular structure.

[0006] Furthermore, a locking plate is fixedly installed on both the front and rear sides of the filter housing, with the top surface of the locking plate being coplanar with the top surface of the filter housing; the top surface of the locking plate has a locking hole a penetrating its bottom surface; a sealing gasket is provided above the filter housing, with a locking hole c penetrating its bottom surface on the top surface of the sealing gasket; a locking plate is provided above the sealing gasket, with a locking hole b penetrating its bottom surface on the top surface of the locking plate.

[0007] Furthermore, when the barrier plate is inserted into the limiting slot, the front and rear ends of the barrier plate are in contact with the front and rear sides of the inner end of the filter tank, respectively, while the top surface of the barrier plate is on the same horizontal plane as the top surface of the filter housing.

[0008] Furthermore, when the locking holes a, c, and b are fixedly installed using bolts and nuts, the bottom surface of the locking plate and the top surface of the filter housing together press against the sealing gasket, at which point the sealing gasket completely seals the top opening of the filter tank.

[0009] Furthermore, a limiting groove is provided on both the front and rear sides of the inner end of the filter tank; a guide plate is slidably inserted into the filter tank, and a limiting block is fixedly installed on both the front and rear faces of the guide plate, and the limiting block is slidably inserted into the limiting groove; when the bottom face of the limiting block contacts the bottom face of the inner end of the limiting groove, the guide plate is inclined with the left side higher than the right side, and its top face is set at a five-degree angle with the top face of the filter housing, and the left end of the guide plate is lower than the connection part between the round pipe and the filter tank.

[0010] Furthermore, when the bottom surface of the limiting insert block contacts the bottom surface of the inner end of the limiting slide groove, the left end surface, front end surface, and rear end surface of the guide plate are in contact with the left side surface, front side surface, and rear side surface of the inner end of the filter tank, respectively, and at this time, the right end of the guide plate is not in contact with the right side surface of the inner end of the filter tank.

[0011] This utility model provides a detachable, anti-clogging filter assembly for water conservancy pipelines, which has the following beneficial effects: The guide plate of this utility model is inclined with the left side higher than the right side, which can guide the water flow to flow smoothly to the right, avoiding direct impact of the water flow on the filter screen plate, reducing the accumulation of impurities and water flow resistance. The filter screen plate forms an inclined filter surface through the inclined barrier plate, which not only increases the filter contact area, but also reduces the probability of impurities adhering to the filter screen surface by means of the water flow impact force and gravity. The inclined design of the bottom of the filter tank with the left side lower than the right side allows the intercepted impurities to slide naturally to the lower left area to accumulate, avoiding accumulation in the filter area. The synergistic effect of multiple structures significantly improves the anti-clogging effect and ensures stable and smooth water flow in the water conservancy pipeline.

[0012] When the locking plate, sealing gasket, and filter housing are fixed by bolt and nut locking components, the locking plate and filter housing together press against the sealing gasket, which can completely seal the top opening of the filter tank. This effectively prevents water from overflowing and external impurities from entering the filter assembly, ensuring the stability of the filtration process and avoiding secondary pollution of the water flow or damage to the internal structure of the assembly by impurities. This improves the protective performance and service life of the assembly. Furthermore, the barrier plate is inserted into the filter housing through a limiting slot, and the guide plate slides through a limiting block and a limiting groove. During disassembly, only the bolt and nut locking components need to be removed, and the locking plate and sealing gasket need to be taken off. The barrier plate can then be easily pulled out to clean the filter screen and the guide plate can be taken out. At the same time, the impurities accumulated in the tank can be thoroughly cleaned through the top opening of the filter tank. No complicated tools or cumbersome steps are required, which greatly shortens the maintenance time and reduces the labor maintenance cost. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example: Please refer to Figures 1 to 5 : This utility model proposes a detachable anti-clogging filter assembly for water conservancy pipelines, comprising: a filter housing 1, a filter groove 103 formed on the top surface of the filter housing 1, and a circular-to-square pipe 101 connected to the filter groove 103 fixedly installed on the upper side of the left and right ends of the filter housing 1; a limiting slot 106 is formed on the front, rear, and right sides of the inner end of the filter groove 103, penetrating the top surface of the filter housing 1; the limiting slot 106 is inclined, forming a 25-degree angle with the right side of the inner end of the filter groove 103, and the bottom of the limiting slot 106 is lower than the connection between the circular-to-square pipe 101 and the filter groove 103; a barrier plate 5 is inserted into the limiting slot 106, and a filter screen plate 501 is embedded in the left and right ends of the barrier plate 5; the bottom surface of the inner end of the filter groove 103 is made of... The filter tank 103 is inclined with the left side lower than the right side, and the bottom surface of the inner end of the filter tank 103 has a semi-circular structure. A locking plate 102 is fixedly installed on the front and rear sides of the filter housing 1. The top surface of the locking plate 102 is coplanar with the top surface of the filter housing 1. The top surface of the locking plate 102 has a locking hole a105 that penetrates its bottom surface. A sealing gasket 3 is provided above the filter housing 1. The top surface of the sealing gasket 3 has a locking hole c301 that penetrates its bottom surface. A locking plate 2 is provided above the sealing gasket 3. The top surface of the locking plate 2 has a locking hole b201 that penetrates its bottom surface. When the barrier plate 5 is inserted into the limiting slot 106, the front and rear ends of the barrier plate 5 are in contact with the front and rear sides of the inner end of the filter tank 103, respectively, while the top surface of the barrier plate 5 is on the same horizontal plane as the top surface of the filter housing 1.

[0018] When locking holes a105, c301, and b201 are fixedly installed using bolts and nuts, the bottom surface of the locking plate 2 and the top surface of the filter housing 1 abut against the sealing gasket 3, at which point the sealing gasket 3 completely seals the top opening of the filter tank 103. A limiting groove 104 is provided on both the front and rear sides of the inner end of the filter tank 103. A guide plate 4 is slidably inserted into the filter tank 103, and a limiting block 401 is fixedly installed on both the front and rear surfaces of the guide plate 4. The limiting block 401 slidably inserts into the limiting groove 104. When the bottom surface of the limiting insert 401 contacts the bottom surface of the inner end of the limiting slide groove 104, the guide plate 4 is set in an inclined position with the left side higher than the right side, and its top surface is set at a five-degree angle with the top surface of the filter housing 1. The left end of the guide plate 4 is lower than the connection part between the round pipe 101 and the filter tank 103. When the bottom surface of the limiting insert 401 contacts the bottom surface of the inner end of the limiting slide groove 104, the left end surface, the front end surface and the rear end surface of the guide plate 4 are in contact with the left side surface, the front side surface and the rear side surface of the inner end of the filter tank 103, respectively. At this time, the right end of the guide plate 4 does not contact the right side surface of the inner end of the filter tank 103.

[0019] The working principle of this embodiment: The filter housing 1 is sealed to the water pipe flange through the round-and-square pipe 101. When the water in the water pipe enters the filter tank 103 of the filter housing 1 through the left round-and-square pipe 101, it first contacts the guide plate 4 in the filter tank 103. Since the guide plate 4 is inclined with the left side higher than the right side, and the left end is lower than the connection between the round-and-square pipe 101 and the filter tank 103, the water will flow smoothly to the right along the inclined surface under the guidance of the guide plate 4, avoiding the water flow from directly impacting the filter screen plate 501 and causing impurities to accumulate. At the same time, it reduces the resistance generated by the water flow impact and ensures the smoothness of the water flow. As the water flows to the right, when it passes through the barrier plate 5 in the limiting slot 106, the filter plate 501 embedded in the barrier plate 5 intercepts and filters solid impurities (such as sand, gravel, and debris) in the water flow. Since the limiting slot 106 is inclined and the barrier plate 5 is tightly attached to the front and rear sides of the filter tank 103, the filter plate 501 forms an inclined filter surface. On the one hand, this increases the filter contact area, and on the other hand, the impact force of the water flow and gravity make it difficult for impurities to adhere to the filter surface, reducing the risk of clogging. The clean water flow after being filtered by the filter plate 501 flows out through the right-side round-and-square pipe 101 and enters the subsequent water pipe. The intercepted impurities fall to the bottom surface of the filter tank 103 under the action of gravity. Since the bottom surface of the inner end of the filter tank 103 is inclined with the left side lower and the right side higher, the impurities will slide naturally along the inclined bottom surface and gather in the low area on the left side of the filter tank 103, avoiding the accumulation of impurities in the filter area and further improving the anti-clogging effect. When the locking holes a105, c301, and b201 are fixed by bolts and nuts, the locking plate 2 and the filter housing 1 press against the sealing gasket 3, completely sealing the top opening of the filter tank 103, preventing water from overflowing or external impurities from entering, and ensuring the sealing and stability of the filtration process. When the impurities accumulated in the filter tank 103 reach a certain amount, the bolts and nuts can be removed, the locking plate 2 and the sealing gasket 3 can be taken off, and the barrier plate 5 can be directly pulled out to clean the filter screen 501. At the same time, the impurities accumulated in the tank can be thoroughly cleaned through the top opening of the filter tank 103. The guide plate 4 can be easily removed through the sliding engagement of the limiting block 401 and the limiting slide groove 104, facilitating a comprehensive cleaning of the inside of the filter tank 103 and enabling quick disassembly and maintenance of the components.
