Description

Technical Field

[0001] This utility model belongs to the field of trash rack technology, specifically relating to an anti-blocking trash rack. Background Technology

[0002] A trash rack is a frame structure installed in front of a water inlet, primarily used to intercept floating debris, suspended solids, and other contaminants carried in the water flow. As the first line of defense in a water treatment system, the trash rack ensures the continuous and efficient operation of water conservancy facilities through physical blocking.

[0003] Chinese patent document CN222975813U discloses an anti-blocking trash rack for water conservancy management. It uses a dual-output shaft motor to drive a worm gear structure, which drives a cleaning basket structure attached to the water inlet side of the trash rack to rise and fall. The cleaning basket structure, which integrates a push auger, can not only scrape and collect impurities on the surface of the trash rack, but also, when raised to a high position, can drive the auger through the drive motor and gear structure to push the impurities out in a directional manner.

[0004] However, in the existing technology, exposing precision transmission components to a harsh aquatic environment full of debris can enable trash racks to clean up impurities and prevent clogging, but it is also very easy to cause problems such as jamming, wear and failure, resulting in a significant reduction in the reliability, durability and maintainability of the trash rack. Therefore, an anti-clogging trash rack is proposed. Utility Model Content

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figures 1-6 As shown, an anti-clogging trash rack includes a trash-blocking component 1 that can intercept trash in water, trash-collecting components 2 that can collect trash on both sides of the trash-blocking component 1, a trash-removing component 3 that can scrape off trash to prevent clogging in front of the trash-blocking component 1, and a drive component 4 that can stably and reliably drive the trash-removing component 3 to operate between the trash-blocking component 1 and the trash-removing component 3.

[0033] In this embodiment: the debris-blocking component 1 includes a main frame 101, debris-blocking plates 102 are fixedly installed on both sides of the main frame 101, and side frames 103 are fixedly connected to both sides of the main frame 101.

[0034] The main frame 101, with its middle section positioned relatively forward and its two sides positioned relatively backward and symmetrically arranged, allows some of the water flowing towards the trash rack to carry the contained debris to both sides of the main frame 101. The trash baffle 102 intercepts the debris that comes into contact with the trash rack over a large area. The side frame 103 provides an installation position for the trash collection assembly 2 and allows the debris to enter the trash collection assembly 2 through its inlet, which coincides with the trash collection bin 201.

[0035] In this embodiment: the sludge collection assembly 2 includes a sludge collection chamber 201 movably connected to the side frame 103, a baffle 202 movably installed at the inlet of the sludge collection chamber 201, and a filter plate 203 movably installed behind the sludge collection chamber 201.

[0036] The side frame 103 is slidably connected to the sludge collection bin 201, and the baffle 202 and filter plate 203 are rotatably connected to the sludge collection bin 201.

[0037] The sludge collection chamber 201, which can be extracted from the top, collects sludge within the side frame 103. A baffle 202, which is installed at the inlet of the sludge collection chamber 201 and can only be rotated into the sludge collection chamber 201 by external force, makes it difficult for sludge entering the sludge collection chamber 201 to flow out from the inlet. The filter plate 203 allows water entering the sludge collection chamber 201 to flow out smoothly, but intercepts sludge entering the sludge collection chamber 201.

[0038] In this embodiment: the decontamination component 3 includes a first insertion post 301 fixedly connected to the upper and lower sides of the main frame 101 respectively. A second insertion post 302 fixedly connected to the main frame 101 is provided in front of and behind the first insertion post 301. A limit rod 303 is fixedly connected between the first insertion post 301 and the second insertion post 302 that are adjacent to each other and have the same height. A translation scraper 304 is movably connected between two limit rods 303 that have the same lateral position but different heights. A bearing seat 305 fixedly connected to the main frame 101 is provided on one side of the lower second insertion post 302. A rotating shaft 306 is movably installed in the bearing seat 305. A rotatable scraper 307 located on one side of the translation scraper 304 is fixedly connected to the front end of the rotating shaft 306.

[0039] The limiting rod 303 is slidably connected to the translation scraper 304, and the bearing seat 305 is rotatably connected to the rotating shaft 306;

[0040] By using the limiting rod 303 positioned by the first insertion post 301 and the second insertion post 302, two vertically arranged translation scrapers 304 are respectively installed in front of the two dirt-blocking plates 102. Through the self-waterproof bearing 305 and the rotating shaft 306, the rotatable scraper 307 can rotate around the axis of the rotating shaft 306 due to external force after being connected to the front end of the rotating shaft 306 protruding from the bearing 305.

[0041] In this embodiment: the drive component 4 includes a traction member that enables some parts of the dirt removal component 3 to effectively scrape off dirt on the dirt barrier 102 or reset it. The traction member includes a rope group 401 fixedly connected between the adjacent translational scraper 304 and the rotatable scraper 307. One end of the rope group 401 is fixedly connected to a vent connector 402. An airbag 403 is fixedly connected to one side of the vent connector 402. A hanging rope 404 is fixedly connected to the bottom of the rotatable scraper 307. A counterweight 405 is fixedly connected to the bottom of the hanging rope 404.

[0042] The drive assembly 4 also includes a reversing component that can adjust the direction of the rope assembly 401 and a venting component that allows the airbag 403 to enter and exit as needed. The reversing component includes a through-ring 406 fixedly installed on the side of the side frame 103 near the other side frame 103. A reversing wheel 407 is provided below the through-ring 406. The venting component includes a three-way connector 408 fixedly installed above the first insertion post 301 at a high position. Air pipes 409 are respectively provided between the three-way connector 408 and the two venting connectors 402. A shut-off valve 410 is fixedly connected above the three-way connector 408. A quick-connect connector 411 is fixedly connected above the shut-off valve 410.

[0043] The rope assembly 401, which passes sequentially through the loop 406 and the reversing pulley 407, connects the translational scraper 304 and the rotatable scraper 307 located in front of the debris barrier 102, as well as the vent joint 402 located behind the debris barrier 102. The rope assembly 401 can be composed of a main rope connecting to the vent joint 402, a first auxiliary rope connecting to the translational scraper 304, a second auxiliary rope connecting to the rotatable scraper 307, and connecting blocks connecting the main rope and each auxiliary rope, so that the airbag 403 can move as buoyancy increases. When the main rope is pulled, the connecting block, which moves with the main rope, can pull the translation scraper 304 and the rotatable scraper 307 respectively via the first and second auxiliary ropes. When both the translation scraper 304 and the rotatable scraper 307 are in the inactive state shown in the attached diagram, to ensure the normal operation of both the translation scraper 304 and the rotatable scraper 307 which abuts against one end of the translation scraper 304, the redundancy of the first auxiliary rope should be greater than that of the second auxiliary rope. This is so that when the connecting block pulls both the first and second auxiliary ropes simultaneously, the redundancy of the second auxiliary rope... The system can be tensioned first, allowing the rotatable scraper 307 to rotate first, followed by the translation of the scraper 304. The main rope of the rope assembly 401 and the inflatable airbag 403 (which can expand when inflated and contract when deflated) are connected via a vent joint 402 that allows gas to flow through. A counterweight 405 is positioned below the rotatable scraper 307 via a suspension rope 404. The counterweight 405 can reset the rotatable scraper 307 when it is not being pulled by the rope assembly 401. The rope assembly is controlled by a loop 406 and a reversing wheel 407. 401 is oriented within this trash rack, and the airbag 403, which floats due to its increased volume, can be smoothly pulled and moved by the rope group 401 to the horizontal scraper 304 and the rotatable scraper 307 as needed. Gas can flow through the air pipe 409 to the components with lower air pressure between the airbag 403 and the three-way connector 408. The gas passage of this trash rack is controlled by the shut-off valve 410. It can be quickly connected to external equipment with the function of sucking in and expelling gas, such as a pump, through the quick-connect connector 411.

[0044] Working principle: When this trash rack is installed and put into use, the quick-connect connector 411 can be connected to an external pump or other equipment through a connecting pipe. The pump or other equipment can supply air to the airbag 403 through the quick-connect connector 411, the shut-off valve 410, the tee connector 408, the air pipe 409, and the vent connector 402, or extract the air from the airbag 403. By changing the size of the airbag 403, the buoyancy of the airbag 403 immersed in water can be adjusted.

[0045] Based on this, when it is necessary to clean the dirt adhering to the debris barrier 102, air can be injected into the airbag 403 to increase its buoyancy. This allows the vent joint 402, which floats with the airbag 403, to be pulled by the rope group 401 to move the translation scraper 304 and rotate the rotatable scraper 307, thereby scraping off the dirt on the debris barrier 102. The scraped-off dirt will enter the debris collection chamber 201 under the combined action of the water flow. After the translation scraper 304 and the rotatable scraper 307 have moved to their limit positions, the air in the airbag 403 can be extracted to reduce its buoyancy. At this time, since the counterweight 405 has a downward pulling effect on the rotatable scraper 307, the rotatable scraper 307 will push the translation scraper 304 to reset together.

[0046] The sludge trapped in the sludge collection chamber 201 can be easily cleaned by staff periodically removing the sludge collection component 2 from the side frame 103 and then opening the filter plate 203.

[0047] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
