Description

Technical Field

[0001] The invention relates to the technical field of gate cleaning, and in particular to a gate device for water conservancy projects which can be automatically cleaned. Background Art

[0002] Hydraulic gates are control facilities used to close and open discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. They are widely used in channels in water conservancy projects.

[0003] The existing gate device is under water for a long time and is easily attached by suspended matter, which corrodes the gate surface and easily affects the opening and closing of the gate. The traditional way to clean the gate is to manually operate it. The staff scrapes off the adhesion on the gate surface with a scraper, and then uses a "bucket-like" tool to dig out the intercepted objects and fallen adhesions in front of the gate. When digging, the bucket will contain water, which is heavy, time-consuming and labor-intensive. Afterwards, the water, intercepted objects and adhesions are poured to the outside of the channel together, causing water loss in the channel, resulting in waste and making it difficult to meet the needs of the staff.

[0016] Compared with the prior art, the present invention provides a gate device for water conservancy projects that can be automatically cleaned, which has the following beneficial effects:

[0017] 1. In real life, the gate will block the intercepted objects in the water and retain them on the water inlet side of the gate. The baffle enters into the channel, and the baffle, gate and both sides of the channel form a "rectangular area". Through the coordinated use of the second stepper motor and the second electric push rod, the bristles can scrape off the adhesion at any position on the water inlet side of the gate. Under the action of the circulating pump, the water in the "rectangular area" is pumped into the water tank. Then the sewage gate is in an open state, and the output end of the third stepper motor and the output end of the third electric push rod cooperate to make the push plate push the intercepted objects and the fallen adhesions to the outside of the "rectangular area". After that, the sewage gate is reset, and the circulating pump pumps water into the "rectangular area" again. The whole process is automated, which changes the traditional way of salvaging intercepted objects, avoids water loss, and meets the needs of staff.

[0018] 2. Since the gate is soaked in water for a long time, it is easy to rust, so the gate needs to be maintained. The present invention adopts the method of spraying corrosion-resistant paint. Since the rusted part of the gate is under water and is difficult to be sprayed, the gate needs to be lifted. However, after the gate is lifted, the water flow will rush to the next gate, so the output end of the first electric push rod is extended again, driving the baffle to move downward into the channel to block the water. Secondly, the gate is lifted, and the rusted part is polished through the paint spraying mechanism, and then the paint spraying head re-sprays the polished area with corrosion-resistant paint, thereby increasing the life of the gate.

Example

[0039] Please refer to Figure 1 , Figure 2 and Figure 6 As shown, the pumping mechanism 3 includes a connecting plate 301, which is welded to the middle left side of the first mounting plate 101, and a first electric push rod 302 is fixedly connected to the top of the connecting plate 301, and a baffle 303 is fixedly installed on the output end of the first electric push rod 302, and a through hole 304 is penetrated at a corner of the baffle 303, and a water tank 305 is arranged on the front side of the top of the channel 1, and a circulating pump 306 is installed on the top of the water tank 305, one end of the circulating pump 306 is connected to a first hose, and the other end of the first hose is fixedly installed in the through hole 304, and a filter is arranged inside the other end of the first hose, and the other end of the circulating pump 306 is connected to the water tank 305 through a second hose.

[0040] It can be understood by those skilled in the art that the baffle 303 can be driven to move downward or upward by extending or retracting the output end of the first electric push rod 302. The height and length of the baffle 303 are matched with the channel 1. The baffle 303 moves downward into the interior of the channel 1.

[0041] Please refer to Figure 1 and Figure 7 As shown, the scraping mechanism 4 includes a second screw rod 401 and a first guide rod 402, the two ends of the second screw rod 401 are rotatably connected to the first mounting plate 101 and the second mounting plate 102 respectively, the outer surface of the second screw rod 401 is threadedly connected with a movable part 404, and a second electric push rod 405 is installed on the top of the movable part 404, the output end of the second electric push rod 405 passes through the top wall of the movable part 404 and is connected to the scraper 406, and the first guide rod 402 is welded between the first mounting plate 101 and the second mounting plate 102, the movable part 404 is slidably connected to the first guide rod 402, and a second stepping motor 403 is arranged on the front side of the second mounting plate 102, and one end of the second screw rod 401 is fixedly connected to the output end of the second stepping motor 403.

[0042] It can be understood by those skilled in the art that the second screw rod 401 is driven to rotate by the output end of the second stepper motor 403, so that the movable part 404 slides back and forth along the outer surface of the first guide rod 402, and secondly, the scraper 406 can be driven to move up and down by the output end of the second electric push rod 405. The outer side of the scraper 406 is provided with bristles, and the bristles are made of flexible material. The bristles can fit the water inlet side of the gate 104. Due to the coordinated use of the second stepper motor 403 and the second electric push rod 405, the bristles can move back and forth and up and down along the surface of the gate 104, so as to scrape off the adhesion at any position on the water inlet side of the gate 104. Example

[0043] Please refer to Figure 8 As shown, the opening and closing mechanism 5 includes a rack 505 and a movable frame 506, support plates 501 are fixedly connected at upper and lower symmetrical positions on the back of the channel 1, and rotating rods 502 are rotatably connected inside the two groups of support plates 501 through bearings.

The rack 505 is fixedly connected to the middle of the outer side of the movable frame 506, and driving strips 507 are rotatably connected at the four corners of the outer side of the movable frame 506. The other end of the driving strip 507 is rotatably connected to the sewage discharge door 105, and a sealing ring and a sealing groove structure are provided at the connection between the sewage discharge door 105 and the back of the channel 1.

[0044] Please refer to Figure 8 As shown, a connecting piece 508 is welded to the top of the back of the channel 1, and an L-shaped groove 509 is opened through the connecting piece 508. A connecting rod 510 adapted to the L-shaped groove 509 is also provided on one set of driving bars 507, and the connecting rod 510 is slidably connected to the inside of the L-shaped groove 509. A transmission motor 504 is fixedly installed on the bottom end of the lower support plate 501, and one end of the rotating rod 502 is fixedly connected to the output end of the transmission motor 504. A track 511 is fixedly connected to the bottom end of the back of the channel 1, and the movable frame 506 is slidably connected to the outer surface of the track 511.

[0045] It can be understood by those skilled in the art that the output end of the transmission motor 504 drives the rotating rod 502 and the gear 503 to rotate as a whole, and then the rack 505 moves to the right, so that the movable frame 506 moves to the right. During the movement of the movable frame 506 to the right, due to the L-shaped groove 509, all the connecting arms rotate, so that the sewage door 105 first moves linearly to disengage from the sewage outlet opened at the back of the channel 1, and then moves horizontally to the right, so that the sewage door 105 is in an open state, otherwise the sewage door 105 is in a closed state. Example

[0046] Please refer to Figure 2 and Fig. 9As shown, the dirt-pushing mechanism 6 includes a connecting block 601, which is provided with two groups and fixedly mounted on the left sides of the first mounting plate 101 and the second mounting plate 102, respectively; a third screw rod 602 is rotatably connected between the two groups of connecting blocks 601; a movable plate 605 is threadedly connected to the outer surface of the third screw rod 602; a push plate 607 is provided directly below the movable plate 605; a third electric push rod 606 is fixedly connected to the top of the movable plate 605; a middle portion of the top end of the push plate 607 is fixedly mounted on the output end of the third electric push rod 606; a second guide rod 603 is also connected between the two groups of connecting blocks 601; the movable plate 605 is slidably connected to the second guide rod 603; one end of the third screw rod 602 is fixedly connected to the output end of the third stepping motor 604; and the third stepping motor 604 is fixedly mounted on the outer side of one of the groups of connecting blocks 601; and the length of the push plate 607 is adapted to the length of the dirt-discharging door 105.

[0047] It can be understood by those skilled in the art that the output end of the third stepper motor 604 drives the third screw rod 602 to rotate, so that the movable plate 605 slides back and forth along the outer surface of the second guide rod 603, and the output end of the third electric push rod 606 can drive the push plate 607 to move up and down. Example

[0048] Please refer to Figure 3 , Figure 4 and Figure 5 As shown, the opening and closing mechanism 2 includes a first sleeve 201, which is fixedly mounted on the top of the top plate 103, and a second sleeve 202, a third sleeve 203 and a fourth sleeve 204 are arranged inside the first sleeve 201, and a mounting member 205 is fixedly mounted inside the first sleeve 201, and a first screw rod 206 is rotatably connected inside the mounting member 205, and one end of the first screw rod 206 away from the mounting member 205 is fixedly connected to the output end of the first stepper motor 207, and the first stepper motor 207 is fixedly mounted on the inner wall of the first sleeve 201, and a driving block 208 is threadedly connected to the outer surface of the first screw rod 206, and the bottom of the fourth sleeve 204 is fixedly connected to the gate 104, and first sealing gaskets 106 are installed on both sides of the gate 104, and a second sealing gasket 107 is also installed at the bottom of the gate 104.

[0049] Please refer to Figure 4As shown, the opening and closing mechanism 2 also includes a fork-type lifting member 213, the first sleeve 201 is internally rotatably connected with the first connecting arm 209 and the second connecting arm 210, two ends of one side of the fork-type lifting member 213 are rotatably connected with the first connecting arm 209 and the second connecting arm 210 respectively, and two ends of the other side of the fork-type lifting member 213 are rotatably connected with the third connecting arm 211 and the fourth connecting arm 212 respectively, the fork-type lifting member 213 is connected to the driving block 208, and the inner walls of the second sleeve 202 and the third sleeve 203 are provided with a sliding groove 215, and a slider 214 adapted to the sliding groove 215 is connected to the fork-type lifting member 213, and the slider 214 is slidably connected with the sliding groove 215.

[0050] It can be understood by those skilled in the art that the output end of the first stepper motor 207 drives the first screw rod 206 to rotate, so that the drive block 208 moves, and the fork-type lifting member 213 is in an extended or retracted state. When extended, the second sleeve 202, the third sleeve 203 and the fourth sleeve 204 all move downward, driving the gate 104 to move downward, and when retracted, the second sleeve 202, the third sleeve 203 and the fourth sleeve 204 all move upward, driving the gate 104 to move upward. The slider 214 is used in conjunction with the slide groove 215 to improve the stability of the movement of the second sleeve 202, the third sleeve 203 and the fourth sleeve 204. Compared with the general structure, this structure has the effect of extending the movement process. Therefore, when used in real life, the top plate 103 can be installed at a higher position, and it can also play the role of opening and closing the gate 104. Example

[0051] Please refer to Fig.10 As shown, the paint spraying mechanism 7 includes a movable frame 704, a fifth screw rod 705 and a movable block 708. A fourth screw rod 701 is rotatably connected between the first mounting plate 101 and the second mounting plate 102. The movable frame 704 is threadedly connected to the fourth screw rod 701. One end of the fourth screw rod 701 is fixedly mounted on the output end of the fourth stepper motor 703. The fourth stepper motor 703 is fixedly connected to the outer top end of the second mounting plate 102. The movable frame 704 is slidably connected to the third guide rod 702. The third guide rod 702 is welded between the first mounting plate 101 and the second mounting plate 102. The fifth screw rod 705 is rotatably connected to the inside of the movable frame 704. A fourth guide rod 706 is also fixedly mounted in the movable frame 704. The movable block 708 is slidably connected to the fourth guide rod 706, and the movable block 708 is threadedly connected to the fifth screw rod 705. A fifth stepper motor 707 is mounted at the bottom of the movable frame 704, and the bottom end of the fifth screw rod 705 is fixedly connected to the output end of the fifth stepper motor 707.

[0052] Please refer to Fig.10As shown, the movable block 708 is internally rotatably connected to a fourth electric push rod 709, and a paint spray head 710 is installed at the output end of the fourth electric push rod 709. The movable block 708 is also internally rotatably connected to a fifth electric push rod 711, and a polishing piece 712 is connected to the output end of the fifth electric push rod 711. Two groups of motors are arranged inside the movable block 708, and the two groups of motors respectively drive the fourth electric push rod 709 and the fifth electric push rod 711 to rotate.

[0053] It can be understood by those skilled in the art that the output end of the fourth stepper motor 703 drives the fourth screw rod 701 to rotate, so that the movable frame 704 slides back and forth along the outer surface of the third guide rod 702; the output end of the fifth stepper motor 707 drives the fifth screw rod 705 to rotate, so that the movable block 708 moves up and down. Therefore, after the gate 104 is lifted, the paint spray head 710 and the grinding piece 712 can move forward and backward and up and down along the surface of the gate 104. Since the gate 104 is soaked in water for a long time, it is easy to be corroded. The rusted part is first polished off by the grinding piece 712. The paint spray head 710 is connected to an external storage cylinder and a liquid inlet pump. The storage cylinder stores corrosion-resistant paint. Under the action of the liquid inlet pump, the paint spray head 710 re-sprays corrosion-resistant paint on the polished area, thereby increasing the life of the gate 104. An alarm and a liquid level sensor are installed on the storage cylinder to remind the staff to add corrosion-resistant paint in advance when the storage cylinder is insufficient. It is worth noting that the polishing piece 712 and the paint spray head 710 in the present invention are both rectangular in shape, and can be rotated separately by two sets of motors, so that there are no dead corners in polishing and spraying.

[0054] The working principle and use process of this device: Figure 1104 , the gate 104 is opened and closed according to the flow of water. In real life, multiple gates 104 are usually set inside the channel 1. The water inlet direction is from the left side of the channel 1 to the right side. The gate 104 will block the intercepted objects in the water and store them on the water inlet side of the gate 104. The output end of the first electric push rod 302 is extended to drive the baffle 303 to move downward into the channel 1. The baffle 303, the gate 104 and the two sides of the channel 1 form a "rectangular area". In addition to the intercepted objects, there will be adhesions on the gate 104. Through the cooperation of the second stepper motor 403 and the second electric push rod 405, the bristles on the scraper 406 can move back and forth and up and down along the surface of the gate 104 to scrape off the adhesions at any position on the water inlet side of the gate 104. Secondly, under the action of the circulating pump 306 The water in the "rectangular area" is pumped into the water storage tank 305, and then the output end of the transmission motor 504 drives the rotating rod 502 and the gear 503 to rotate as a whole, and then the rack 505 moves to the right, so that the movable frame 506 moves to the right. In the process of the movable frame 506 moving to the right, due to the L-shaped groove 509, all the connecting arms rotate, so that the sewage door 105 first moves linearly and disengages from the sewage outlet opened at the back of the channel 1, and then the sewage door 105 moves horizontally to the right, so that the sewage door 105 is in an open state, and then the output end of the third stepper motor 604 and the output end of the third electric push rod 606 cooperate to make the push plate 607 push the intercepted objects and the fallen adhesions to the outside of the "rectangular area", and the rear sewage door 105 is reset, and the circulation pump 306 pumps water into the "rectangular area" again, meeting the needs of the staff;

[0055] Since the gate 104 is soaked in water for a long time, it is easy to be corroded, so the gate 104 needs to be maintained. The present invention adopts the method of spraying corrosion-resistant paint. Since the rusted part of the gate 104 is under water and is difficult to be sprayed, the gate 104 needs to be lifted. However, after the gate 104 is lifted, the water flow will rush to the next gate 104, so the output end of the first electric push rod 302 is extended again, driving the baffle 303 to move downward into the channel 1 to block the water. Secondly, the gate 104 is lifted, and the rusted part is polished by the paint spraying mechanism 7, and then the paint spraying head 710 re-sprays the polished area with corrosion-resistant paint, thereby increasing the life of the gate 104.
