Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project gate filtering mechanism. Background Art

[0002] A gate is a hydraulic engineering structure built on rivers and channels to control flow and regulate water levels. It is widely used to discharge floods, waterlogging, abandoned water or wastewater, and to supply water to downstream rivers or channels. The gate filter mechanism is the grille or filter in front of the gate, which is used to filter out small or large impurities.

[0003] A water conservancy project gate filtering mechanism with application number 202322297173.1 includes a gate body, a gate pier, a controller, and a filter plate. The filter plate is installed at the bottom of the gate pier. The gate body and the gate pier can slide up and down relative to each other. The gate body is connected to a lifting device for driving it to move up and down; a lifting device is installed on the gate pier, and the lifting device is used to drive the lifting plate to move up and down; the lifting plate is fixedly connected to a lifting bracket, and a left-right moving mechanism is installed on the lifting bracket. The utility model can move one of the hooking plate and the cleaning brush on the outside of the cleaning tank to one side of the filter plate and the other to one side of the cleaning tank by adjusting the motor and other components inside the cleaning tank. It can not only remove large garbage on the outer surface of the filter plate, but also clean the stains on the outer surface of the filter plate, and the cleaning effect is good.

[0004] The cleaning method adopted in this technical solution is that after cleaning, the garbage is still in front of the filter structure. When the sluice gate is opened next time, the water flow will wash the garbage to the surface of the filter structure. The cleaning effect is poor, but it causes more and more garbage to pile up, resulting in increased resistance and difficulty in the operation of the filter structure. In addition, additional electrical appliances need to be set up as active components in the working process, which increases energy consumption and leads to increased costs. In order to prevent the power supply from being affected by water and causing a short circuit, better sealing is required, which further increases the cost. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a water conservancy project gate filtering mechanism to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water conservancy project gate filtering mechanism, including an embedded seat, a gate and a sluice gate, a telescopic rod is fixed on one side of the sluice gate, and one end of the telescopic rod is connected to a bracket, a scraper is connected to one side of the bottom of the bracket, sliders are fixed above the outer surface and above the back of the bracket, a discharge port is provided on the outer surface of the gate, a slide groove is provided on the inner wall of the gate, and a first baffle plate and a second baffle plate are respectively connected to the inside of the slide groove through two torsion spring shafts.

[0007] By adopting the above technical scheme, when the water gate is opened and moved upward, the support, the slider and the scraper are driven to move upward by the telescopic rod. After the scraper moves upward, the impurities on the surface of the filter screen are scraped off and collected. As the telescopic rod, the support, the slider and the scraper continue to move upward, the slider pushes the first baffle to make the first baffle rotate upward. When the slider is located at the top of the slide groove, the first baffle is driven by the torsion spring shaft to rotate downward, and at the same time, the scraper corresponds to the discharge port, and the impurities collected by the scraper are rolled downward and discharged from the discharge port through the slope at the top of the scraper, so as to avoid the garbage after cleaning still being on the right side of the filter screen. When the water gate is closed and moved downward, the slider is against the first baffle, so that the support and the scraper are deflected to the right, and the telescopic rod is forced to retract and retract. As the telescopic rod, the support, the slider and the scraper continue to move downward, the slider pushes the second baffle to make the second gear handle rotate to the left. When the slider is located at the bottom point of the slide groove, the second baffle is driven by the torsion spring shaft to rotate downward, and the scraper is located at the lower right side of the filter screen. When the water gate is opened again, the filter screen can be cleaned again.

[0008] Furthermore, the top of the scraper frame is sloped, and the cross-section of the scraper frame is "L"-shaped.

[0009] By adopting the above technical solution, the scraper moves up to scrape and collect impurities on the surface of the filter screen. When the scraper corresponds to the discharge port, the impurities collected by the scraper roll downward and are discharged from the discharge port through the slope on the top of the scraper.

[0010] Furthermore, the slide groove is in an isosceles trapezoidal shape, and the bracket is slidably connected to the slide groove via a slider.

[0011] By adopting the above technical solution, the bracket and the scraper are guided by the slide groove and the slider, so as to prevent the scraper bracket from moving downward and scraping impurities on the surface of the filter to the bottom of the scraper, which is difficult to clean.

[0012] Furthermore, the sliding block is respectively in contact with the first baffle plate and the second baffle plate, and the first baffle plate and the second baffle plate are both slidably connected with the sliding groove via a torsion spring shaft.

[0013] By adopting the above technical solution, when the slider moves upward, the first baffle is pushed open to cause the first baffle to rotate upward. When the slider is located at the top of the slide groove, the first baffle is driven by the torsion spring shaft to rotate downward. When the slider moves downward, the second baffle is pushed open to cause the second gear handle to rotate to the left. When the slider is located at the bottom of the slide groove, the second baffle is driven by the torsion spring shaft to rotate downward.

[0014] Furthermore, the gate is fixed to the top of the embedded seat, and a hydraulic cylinder is installed on the top of the gate, a guide rail is arranged inside the gate, and the water gate is connected between the hydraulic cylinder and the guide rail, and a filter is installed below the inside of the gate.

[0015] By adopting the above technical solution, when it is necessary to open the gate, the output end of the hydraulic cylinder drives the sluice gate to move upward, and at the same time guides the sluice gate through the guide rail. After the sluice gate moves upward, the gate is opened. At this time, the water flow can pass through the gate channel and the filter from the right side of the gate to the left side of the gate. When it is necessary to close the gate, the output end of the hydraulic cylinder drives the sluice gate to move downward, and at the same time guides the sluice gate through the guide rail. After the sluice gate moves downward, the gate is closed. At this time, the water flow cannot pass through the gate channel and the filter from the right side of the gate to the left side of the gate.

[0016] Furthermore, the scraper frame is slidably connected to the filter screen.

[0017] By adopting the above technical solution, the scraper frame moves up to scrape off and collect impurities on the surface of the filter, thereby preventing the cleaned garbage from remaining on the right side of the filter.

[0018] Furthermore, a water pump is installed on one side of the gate, and the water inlet end of the water pump is connected to a pumping pipe, and the water outlet end of the water pump is connected to a flushing pipe.

[0019] By adopting the above technical solution, if there are a lot of residual impurities on the scraper or the impurities are very viscous, making it difficult for the impurities to be discharged to the discharge port by gravity, the staff can turn on the water pump. After the water pump is started, water is pumped into the flushing pipe through the suction pipe. Then the flushing pipe sprays water on the top of the scraper, thereby flushing away the impurities on the top of the scraper to achieve a cleaning effect.

[0020] Furthermore, one end of the flushing pipe extends to the middle of the back of the gate.

[0021] By adopting the above technical solution, the flushing pipe sprays water to the top of the scraper frame, thereby washing away impurities on the top of the scraper frame to achieve a cleaning effect.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a discharge port, a scraper, a chute, a first baffle, a second baffle, a torsion spring shaft and a telescopic rod. When the sluice gate is opened and moved upward, the telescopic rod drives the bracket, the slider and the scraper to move upward. After the scraper moves upward, the impurities on the surface of the filter screen are scraped off and collected. As the telescopic rod, the bracket, the slider and the scraper continue to move upward, the slider pushes the first baffle to rotate upward. When the slider is located at the top of the chute, the first baffle is driven by the torsion spring shaft to rotate downward, and at the same time, the scraper corresponds to the discharge port, and the impurities collected by the scraper are rolled downward and discharged from the discharge port through the slope at the top of the scraper, so as to avoid the impurities after cleaning. The garbage is still on the right side of the filter. When the sluice gate is closed and moved downward, the slider is against the first baffle, causing the bracket and the scraper to shift to the right. At the same time, the telescopic rod is retracted and extended. As the telescopic rod, bracket, slider and scraper continue to move downward, the slider pushes open the second baffle and the second gear handle turns left. When the slider is at the bottom point of the slide slot, the second baffle is driven downward by the torsion spring shaft. At the same time, the scraper is located at the lower right side of the filter. When the sluice gate is opened again, the filter can be cleaned again. The opening and closing of the sluice gate drives the movement of the cleaning structure, which is convenient for automatic cleaning of the filter. At the same time, there is no need to add additional electrical appliances to reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1:

[0035] A water conservancy project gate filtering mechanism, such as Figure 1-7 As shown, it includes an embedded seat 1, a gate 2 and a water gate 5. A telescopic rod 18 is fixed on one side of the water gate 5. One end of the telescopic rod 18 is connected to a bracket 11. A scraper 10 is connected to one side of the bottom of the bracket 11. The scraper 10 is slidably connected to the filter 13. The cross section of the scraper 10 is "L" shaped. When the water gate 5 is opened and moved upward, the telescopic rod 18 drives the bracket 11, the slider 12 and the scraper 10 to move upward. After the scraper 10 moves upward, the impurities on the surface of the filter 13 are scraped off and collected; the top of the scraper 10 is sloped, and a discharge port 9 is opened on the outer surface of the gate 2. The scraper 10 corresponds to the discharge port 9. The impurities collected by the scraper 10 are rolled downward and discharged from the discharge port 9 through the slope on the top of the scraper 10.

[0036] A slider 12 is fixed on the upper part of the outer surface and the upper part of the back of the bracket 11, and a slide groove 14 is opened on the inner wall of the gate 2. The slide groove 14 is an isosceles trapezoid. The bracket 11 is slidably connected to the slide groove 14 through the slider 12. The inside of the slide groove 14 is respectively connected with a first baffle 15 and a second baffle 16 through two torsion spring shafts 17. The slider 12 abuts against the first baffle 15 and the second baffle 16 respectively. The first baffle 15 and the second baffle 16 are slidably connected to the slide groove 14 through the torsion spring shaft 17. When the slider 12 moves up, the first baffle 15 is pushed open to make the first baffle 15 rotate upward. When the slider 12 is located at the top of the slide groove 14, the first baffle 15 is driven by the torsion spring shaft 17 to rotate downward. When the slider 12 moves downward, the second baffle 16 is pushed open to make the second gear handle rotate to the left. When the slider 12 is located at the bottom point of the slide groove 14, the second baffle 16 is driven by the torsion spring shaft 17 to rotate downward.

[0037] See also Figure 1 Figure 4 In the above embodiment, the gate 2 is fixed to the top of the embedded seat 1, a hydraulic cylinder 3 is installed on the top of the gate 2, a guide rail 4 is arranged inside the gate 2, a water gate 5 is connected between the hydraulic cylinder 3 and the guide rail 4, and a filter screen 13 is installed at the bottom of the gate 2. When the gate needs to be opened, the output end of the hydraulic cylinder 3 drives the water gate 5 to move upward, and at the same time guides the water gate 5 through the guide rail 4. After the water gate 5 moves upward, the gate is opened. At this time, the water flow can flow from the right side of the gate through the gate 2 and the filter screen 13 to the left side of the gate.

[0038] Embodiment 2:

[0039] On the basis of the above-mentioned embodiment 1, although by setting the discharge port 9, scraper 10, slide 14, first baffle 15, second baffle 16, torsion spring shaft 17 and telescopic rod 18, the cleaning structure can be driven to move by the opening and closing of the water gate, so as to facilitate the automatic cleaning of the filter 13, and no additional electrical appliances are required to reduce costs; but if there are more impurities remaining on the scraper 10 or the impurities are more viscous, it will be difficult for the impurities to be discharged to the discharge port 9 by gravity; now by setting a water pump 6, a suction pipe 7 and a flushing pipe 8, the impurities on the top of the scraper 10 can be washed away to achieve a cleaning effect.

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In the above embodiment, a water pump 6 is installed on one side of the gate 2, the water inlet end of the water pump 6 is connected to a pumping pipe 7, the water outlet end of the water pump 6 is connected to a flushing pipe 8, one end of the flushing pipe 8 extends to the middle of the back of the gate 2, after the water pump 6 is started, water is pumped into the flushing pipe 8 through the pumping pipe 7, and then the flushing pipe 8 sprays water on the top of the scraper 10, thereby flushing away impurities on the top of the scraper 10 to achieve a cleaning effect.

[0041] The implementation principle of the utility model is as follows: first, when the gate needs to be opened, the output end of the hydraulic cylinder 3 drives the water gate 5 to move upward, and guides the water gate 5 through the guide rail 4. After the water gate 5 moves upward, the gate is opened. At this time, the water flow can flow from the right side of the gate through the gate channel 2 and the filter screen 13 to the left side of the gate. When the gate needs to be closed, the output end of the hydraulic cylinder 3 drives the water gate 5 to move downward, and guides the water gate 5 through the guide rail 4. After the water gate 5 moves downward, the gate is closed. At this time, the water flow cannot flow from the right side of the gate through the gate channel 2 and the filter screen 13 to the left side of the gate.

[0042] When the sluice gate 5 is opened and moved upward, the support 11, the slider 12 and the scraper 10 are driven upward by the telescopic rod 18, and the slider 12 is limited by the second baffle 16 to prevent the slider 12 and the chute 14 from driving the support 11 to deviate to the right at this time. After the scraper 10 moves upward, the impurities on the surface of the filter screen 13 are scraped off and collected. As the telescopic rod 18, the support 11, the slider 12 and the scraper 10 continue to move upward, the slider 12 pushes the first baffle 15 to rotate upward. When the slider 12 is located at the top of the chute 14, the first baffle 15 is driven by the torsion spring shaft 17 to rotate downward, and at the same time, the scraper 10 corresponds to the discharge port 9, and the impurities collected by the scraper 10 are rolled downward and discharged from the discharge port 9 through the slope at the top of the scraper 10, so as to prevent the cleaned garbage from still being on the right side of the filter screen 13;

[0043] If there are too many residual impurities on the scraper 10 or the impurities are too sticky, making it difficult for the impurities to be discharged to the discharge port 9 by gravity, the staff can turn on the water pump 6. After the water pump 6 is started, water is pumped into the flushing pipe 8 through the pumping pipe 7. Then the flushing pipe 8 sprays water on the top of the scraper 10, thereby flushing away the impurities on the top of the scraper 10 to achieve a cleaning effect;

[0044] When the sluice gate 5 is closed and moved downward, the slider 12 abuts against the first baffle 15, causing the bracket 11 and the scraper 10 to shift to the right, and at the same time, the telescopic rod 18 is forced to retract. As the telescopic rod 18, the bracket 11, the slider 12 and the scraper 10 continue to move downward, the slider 12 pushes open the second baffle 16 and the second gear handle rotates to the left. When the slider 12 is located at the bottom point of the slide groove 14, the second baffle 16 is driven by the torsion spring shaft 17 to rotate downward. At the same time, the scraper 10 is located at the lower right side of the filter screen 13. When the sluice gate 5 is opened again, the filter screen 13 can be cleaned again.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
