Description

Technical Field

[0001] The utility model relates to the field of water conservancy project filtering equipment, in particular to a filtering device for water conservancy projects. Background Art

[0002] According to the patent document with the announcement number CN221618784U, the motor 1 drives the rotating shaft 2 and the first transmission wheel to rotate at the same time, and the rotating shaft 2 is used to drive the filter to rotate to lift the debris upward to the auger, and the filter is cleaned by the roller brush and the scraper, and then the auger is driven by the second transmission wheel and the belt to rotate to send the debris out;

[0003] This patent document intercepts debris at the outlet of a water conservancy project. Since the entire baffle is fixed on the dam body, when it rains heavily and needs to drain water downstream, the entire filtering structure cannot quickly remove it from the outlet, and the discharged water will contain a large amount of sand and debris. The sand and gravel in the entire water body are prone to accumulate at the lower end of the filter, and are also prone to clogging the filter, affecting the flow of the water body, resulting in a slower drainage speed, which may then cause a more serious water conservancy accident.

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] As shown in Figure 1- Fig. 9 As shown, a filtering device for water conservancy projects includes a waterproof mechanism 1, and one side of the waterproof mechanism 1 is provided with a filtering mechanism 3 for filtering and separating debris and sand in the water and a cleaning mechanism 2 for cleaning the debris in the water.

[0032] In this embodiment: the cleaning mechanism 2 includes a filter tank frame 21, a lifting frame 22 is fixed on both sides of the filter tank frame 21, a guide port is opened on one side of the upper end of the lifting frame 22, and a guide pipe 23 for guiding water out is fixed at the lower end of the lifting frame 22. A slot for allowing debris and sand to enter is opened at the outer side of the lifting frame 22 located inside the filter tank frame 21, and a filter plate 26 for separating sand and debris in the water is fixed at the bottom side of the lifting frame 22. A filter auger 25 rotating inside the lifting frame 22 is provided above the filter plate 26, and a driving motor 24 is fixed to the filter auger 25. Discharge ports are opened at positions near the lifting frame 22 on both sides of the filter tank frame 21, and the two ends of the guide tank 4 are respectively connected from the filter Two outlets of the trough frame 21 extend out, and leakage holes for allowing water to flow through are opened on the spiral blades of the filtering auger 25. The lifting frames 22 on both sides of the filtering trough frame 21 are used to collect the debris and sand blocked by the filtering mechanism 3, and the filter plate 26 at the bottom of the lifting frame 22 is used to filter the debris and sand. Then, the filtering auger 25 is driven to rotate by the rotating part of the driving motor 24, so as to lift the debris and sand accumulated on the filter plate 26 upward and send it out from the outlet of the lifting frame 22. In this process, the moisture in the debris and sand is leaked out through the leakage holes on the spiral blades of the filtering auger 25, and the water inside the lifting frame 22 will be sent to a position close to the waterproof mechanism 1 through the outlet pipe 23.

[0033] In this embodiment: the filter mechanism 3 includes a cross frame 31, both ends of the cross frame 31 are fixed inside the filter slot frame 21, two filter flaps 34 are arranged below the cross frame 31, and a scraper 33 is arranged on the side of the two filter flaps 34 away from the waterproof mechanism 1, and a lifting hydraulic rod 32 is fixed on the top of the scraper 33, and the fixed part of the lifting hydraulic rod 32 is fixedly connected to the cross frame 31, and a guide groove 4 is arranged on the side of the two filter flaps 34 close to the waterproof mechanism 1, and a rotating shaft 5 for rotating and supporting the filter flap 34 is fixed at the position of the notch of the lifting frame 22 close to the guide groove 4, and the two filter flaps 34 are arranged in a The inverted V-shaped structure is distributed, and two filter flaps 34 in an inverted V-shaped structure are used in the filter tank frame 21 to filter debris and sand in the water. At the same time, the floating debris or sand will enter the lifting frame 22 along the V-shaped surface formed by the two filter flaps 34. In addition, the telescopic part of the lifting hydraulic rod 32 drives the scraper 33 to move up and down at the V-shaped surface of the two filter flaps 34, so as to cut off and clean the aquatic plant branches hanging on the filter flaps 34, and the scraper 33 moves upward to scrape the plant branches into the outlet trough 4, and then send them out from the two ends of the outlet trough 4.

[0034] In this embodiment: the waterproof mechanism 1 includes a sluice bracket 11, a lifting door 13 is slidably connected to the inner side of the sluice bracket 11, a screw 12 is provided in the middle of the lifting door 13 for driving it to move upward, the sluice bracket 11 is fixedly connected to the filter tank rack 21, and a water outlet for discharging water is provided on the side where the sluice bracket 11 and the filter tank rack 21 are in contact with the lifting door 13. The lifting door 13 is driven to move upward along the inside of the sluice bracket 11 by rotating the screw 12, so that the water on one side of the sluice bracket 11 is discharged through the water outlet.

[0035] Working principle: When using the filtering device, firstly, the screw 12 is driven to rotate by the corresponding driving device, and the rotation of the screw 12 drives the lifting door 13 to move upward along the inside of the sluice bracket 11, and then a certain gap is opened at the lower side of the water outlet, so that the water is discharged downstream;

[0036] During the water discharge process, the flowing water is filtered by two inverted V-shaped filter flaps 34. As the water flows, the debris and sand carried in the water will be blocked by the filter flaps 34 on the inner side of the filter tank frame 21, and then the debris or sand will be gathered to the two lifting frames 22 through the V-shaped surface formed by the two filter flaps 34. The water flow gathered inside the lifting frame 22 will be guided to the other side of the filter flap 34 through the outlet pipe 23, and then a vortex will be formed inside the lifting frame 22, which will accelerate the gathering of debris and sand in the lifting frame 22. In this process, the debris and sand are filtered by the filter plate 26 to prevent the debris and sand from flowing out along the outlet pipe 23.

[0037] When the debris and sand in the lifting frame 22 accumulate to a certain amount, the filter auger 25 is driven to rotate by the rotating part of the driving motor 24, and the debris and sand on the filter plate 26 are scraped off by the lower end of the filter auger 25, and the sand and debris are transported upward by the rotation of the filter auger 25. After the debris and sand are transported to the outlet of the lifting frame 22, the cleaning of the sand and debris is completed;

[0038] In addition, the water also carries some plant debris, which will hang on the filter flap 34. At this time, the hydraulic rod 32 is lifted to drive the scraper 33 to move upward along the V-shaped surface of the two filter flaps 34, so as to scrape up the plant debris hanging on the two filter flaps 34. The plant debris scraped by the scraper 33 will separate from the filter flap 34. At this time, the plant debris will follow the scraper 33 to move upward and be sent into the outlet trough 4, and the plant debris will be sent out from the outlet through the outlet trough 4.

[0039] When heavy rain occurs and emergency drainage is required downstream, the two filter flaps 34 are moved closer to each other at one end, so that the two filter flaps 34 are flipped toward the two sides of the filter tank frame 21 with the rotating shaft 5 of the lifting frame 22 as the center, and then the two filter flaps 34 are respectively attached to the two sides of the inside of the filter tank frame 21, which can speed up the flow of water and avoid the situation where the water outlet is blocked during emergency drainage.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
