Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a filtering and impurity removing device for a water channel of a water conservancy engineering. Background Art

[0002] A canal is a man-made waterway, which can be divided into a main canal and a branch canal. The main canal and the branch canal are generally built with stone or cement. The canal is an important channel structure in water conservancy projects, and plays the role of conveying water, diverting water for power generation, and agricultural irrigation. The shape of a canal is generally small in width and long in length. Water flowing inside the canal is prone to carry more impurities, and it is necessary to install a filtering and impurity removal device in the canal to filter and remove impurities in the canal. However, when the existing water conservancy project canal uses a filtering and impurity removal device to filter and remove impurities in the canal, due to the different widths of the canal, the filtering and impurity removal device is difficult to match the width of the inside of the canal, resulting in gaps after the filtering and impurity removal device is installed in the canal. Different canals require filtering devices of different sizes, which is costly.

[0003] Chinese patent CN118686133A discloses a filtering and impurity removal device for water conservancy projects, the structure of which includes an adjustment frame, a threaded groove frame, a threaded rod, a contact rod, and a connecting mechanism, and the outer end surface of the adjustment frame is welded with a threaded groove frame. The device adjusts the left and right brackets on both sides according to the width of the water channel to improve the fit when installed inside water channels of different widths, but the area of ​​the filter screen does not change. When filtering water channels of different widths, the effective filtering area remains unchanged and cannot meet the filtration of all sewage. If the sewage is guided through a filter screen of a single size, the water level at that location will rise, which is not conducive to the smooth flow of water in the drainage channel.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 11 :

[0034] A filtering and impurity removal device for a water conservancy project water channel comprises a filter assembly 1 and two mounting frames 2 arranged at both ends of the filter assembly 1 for fixing the filter assembly 1 in a drainage channel. The filter assembly 1 comprises a rectangular mounting frame 11, the length of the mounting frame 11 is greater than the width of the drainage channel, the mounting frame 11 is tiltedly arranged in the drainage channel, and a plurality of filter lines 12 (such as Figure 5 As shown), the filter lines 12 are evenly spaced in the vertical direction; the filter assembly 1 is provided with a vertical first shaft 111 (combined with Figure 3 , Figure 4 and Fig.10), a plug-in sleeve 21 is provided on the mounting frame 2, and the mounting frame 2 is sleeved on the first shaft 111 of the filter component 1 through the plug-in sleeve 21; a plurality of first screw holes 22 are provided on the mounting frame 2, and the axis of the first screw hole 22 is perpendicular to the side wall of the drain channel; a sliding frame 23 is slidably installed on the mounting frame 2, and the sliding frame 23 moves along the vertical direction to fit the top of the side wall of the drain channel, and a plurality of second screw holes 231 are provided on the sliding frame 23, and the axis of the second screw hole 231 is vertically arranged; a cleaner 3 for cleaning the filter line 12 is provided on the filter component 1, and a collecting component 4 is provided on the side of the downstream mounting frame 2 facing the water flow direction, and the collecting component 4 is used to collect impurities filtered by the filter component 1.

[0035] In the present application, the first shaft 111 of the filter assembly 1 is inserted into the plug-in sleeve 21 of the mounting frame 2, so that the filter assembly 1 is rotatably connected to the mounting frame 2. Since the length of the mounting frame 11 is greater than the width of the drain channel, its inclination angle can be adjusted according to the actual width of the drain channel to adapt to drain channels of different widths. The sliding frame 23 on the sliding mounting frame 2 is moved in the vertical direction to fit the top of the drain channel side wall, and then the mounting frame 2 is fixed on the drain channel side wall of different depths by screwing screws into the first screw hole 22 and the second screw hole 231, thereby completing the installation of the entire device. The water flows in the drain channel and passes through the inclined filter assembly 1. Impurities in the water, such as plastic bags, branches or leaves, can be intercepted by the filter lines 12 extending horizontally and distributed vertically at equal intervals in the mounting frame 11, and the water continues to flow through the gaps between the filter lines 12 to achieve filtering and impurity removal. The projected length of the filter line 12 in the width direction of the drain channel is the same as the actual width of the drain channel, so it can cover drain channels of different widths, and the projection of the distance between the filter lines 12 in the width direction of the drain channel will not change due to the inclination of the mounting frame 11. Compared with the traditional filter screen, it can avoid the increase in the inclination angle causing the water flow path to become longer (after the circular filter hole of the filter screen is tilted, the projection in the direction of water flow movement will change from a circle to an ellipse), increase resistance, significantly slow down the flow rate, and reduce drainage efficiency. The cleaner 3 on the filter assembly 1 cleans the filter line 12 that intercepts impurities to prevent the filter line 12 from being blocked and affecting the filtering effect. The cleaned impurities and the impurities directly intercepted by the filter line 12 are collected by the collection assembly 4 located on the side of the downstream mounting frame 2 facing the water flow direction under the action of the water flow, which is convenient for subsequent centralized processing. The existing technology is difficult to match the interior of water channels of different widths, and it is costly to set up filter devices of different sizes. In this embodiment, the length of the mounting frame 11 is greater than the width of the drainage channel and is tilted, so that it can adapt to drainage channels of different widths by changing the tilt angle, without the need to customize filter devices of different sizes for different channels, thereby reducing costs. In this embodiment, a cleaner 3 is provided to clean the filter line 12, and a collection component 4 is provided to collect impurities, thereby facilitating the maintenance of the filter device, maintaining its good filtering performance, and extending its service life.

[0036] In order to ensure the tightness of the mounting frame 2 when it is attached to the side wall of the drainage channel, the following features are specifically provided:

[0037] A fitting rubber 24 is provided on one side of the mounting frame 2 facing the side wall of the drainage channel, and the fitting rubber 24 is used to fit the side wall of the drainage channel.

[0038] In this embodiment, the staff adjusts the angle of the inclined mounting frame 11 according to the width of the drain channel to adapt it to drain channels of different widths. Then, the sliding frame 23 on the sliding mounting frame 2 is moved in the vertical direction until it fits the top of the drain channel side wall. At this time, the fitting rubber 24 of the mounting frame 2 facing the drain channel side wall is in close contact with the drain channel side wall. Finally, by screwing screws into the first screw hole 22 and the second screw hole 231, the mounting frame 2 is firmly fixed on the drain channel side wall to complete the installation of the entire filtering and impurity removal device. In this embodiment, the fitting rubber 24 can fit the side wall tightly, effectively fill the possible gaps, prevent water leakage, ensure that all water flows through the filter assembly 1 for filtration, and improve the integrity and efficiency of filtration.

[0039] In order to achieve the purpose of moving all the impurities intercepted on the filter line 12 to the collection assembly 4 at the downstream, the following features are specifically set:

[0040] The cleaner 3 includes a vertically arranged scraper 31, on which a through hole 311 is arranged on the same straight line as each filter line 12, and each filter line 12 is respectively inserted into a through hole 311; the cleaner 3 also includes a first driving unit 32 for driving the scraper 31 to move horizontally along the length direction of the filter component 1, and the first driving unit 32 drives the scraper 31 to move the impurities filtered by the filter line 12 to the collection component 4.

[0041] The first driving unit 32 includes a first conveyor belt 321 installed on the top of the installation frame 11, and a moving block 322 is fixedly installed on the first conveyor belt 321. The first conveyor belt 321 drives the moving block 322 to reciprocate along the length direction of the installation frame 11 at the top of the installation frame 11; a plug rod 323 extending vertically downward is provided at the bottom of the moving block 322, and the plug rod 323 is plug-connected with the plug-in block 312 provided on the top of the scraper 31.

[0042] In this embodiment, when the filter line 12 needs to be cleaned after intercepting impurities for a period of time, the first driving unit 32 works, and the first conveyor belt 321 installed on the top of the installation frame 11 is started. The first conveyor belt 321 can be a chain conveyor belt driven by a servo motor. The first conveyor belt 321 drives the moving block 322 fixed thereon to move along its length direction at the top of the installation frame 11. Because the plug rod 323 at the bottom of the moving block 322 is plugged and connected with the plug-in block 312 at the top of the scraper 31, the scraper 31 moves horizontally along the length direction of the filter component 1 synchronously. The scraper 31 is provided with a through hole 311 in the same straight line as each filter line 12, and each filter line 12 is inserted therein. When the scraper 31 moves, the impurities on the filter line 12 and the impurities intercepted by the filter line 12 are scraped and pushed to the collection component 4 located downstream, and the impurities are continuously concentrated within the collection range of the collection component 4, completing the impurity collection process. Compared with the prior art, this embodiment can automatically and efficiently clean and transfer impurities on the filter line 12 through the cooperation between the scraper 31 and the first drive unit 32, thereby improving the efficiency and timeliness of impurity cleaning, maintaining the filtering performance of the filter line 12, and ensuring stable operation of the device; the through holes 311 on the scraper 31 are inserted into the filter lines 12 one by one, so that the cleaning of each filter line 12 is more accurate and thorough, and the residual impurities are effectively reduced; the first drive unit 32 adopts the method of the first conveyor belt 321 to drive the moving block 322, which has a simple structure, is easy to implement and maintain, has low cost and high stability, reduces the probability of device failure, and is conducive to long-term stable operation.

[0043] In order to ensure that the scraper 31 moves along the length direction of the filter line 12 and does not apply external forces in other directions to the filter line 12 to cause the filter line 12 to bend, the following features are specifically set:

[0044] A first limiting hole 112 penetrating the top side of the mounting frame 11 is disposed on the top of the mounting frame 11 . The first limiting hole 112 extends along the length direction of the mounting frame 11 . The width of the first limiting hole 112 is the same as the diameter of the insertion rod 323 .

[0045] In this embodiment, when the first driving unit 32 starts to work, the first conveyor belt 321 drives the moving block 322 to move back and forth along the length direction at the top of the installation frame 11, and the insertion rod 323 extending vertically downward at the bottom of the moving block 322 will move accordingly. Since the top of the installation frame 11 is provided with a first limiting hole 112 extending along its length direction and penetrating the top side, and the width of the first limiting hole 112 is the same as the diameter of the insertion rod 323, the insertion rod 323 can just move in the first limiting hole 112. This makes the insertion rod 323 move only along the direction defined by the first limiting hole 112, that is, the length direction of the installation frame 11. Because the insertion rod 323 is plugged into the insertion block 312 on the top of the scraper 31, the scraper 31 can only move along the length direction of the filter line 12. This embodiment strictly limits the movement direction of the insertion rod 323 through the first limiting hole 112, thereby ensuring that the scraper 31 will not apply any external force to the filter line 12 except along its length direction, effectively protecting the filter line 12, extending the service life of the filter line 12, and reducing the frequency and cost of replacing the filter line 12 due to damage to the filter line 12.

[0046] In order to enable the impurities filtered by the filter assembly 1 and accumulated on the downstream mounting frame 2 by the water flow and the cleaner 3 to be discharged to the outside of the drain channel, the following features are specifically provided:

[0047] The collecting assembly 4 includes a base 41, on which a connecting block 411 (such as Fig.10 As shown in FIG. 1 , the base 41 is fixedly connected to the mounting frame 2 near the downstream of the drainage channel through a connecting block 411, and the base 41 is located on the side of the mounting frame 2 facing the upstream of the water flow; a lifting box 42 is slidably mounted on the base 41, and the opening of the base 41 faces the side of the filter assembly 1, and a plurality of horizontal shovel teeth 421 (as shown in FIG. 1 ) are arranged at the bottom of the lifting box 42. Figure 1 and Figure 7 The base 41 is provided with a second driving unit 43 for driving the lifting box 42 to move in the vertical direction and to flip the lifting box 42 to the outside of the drainage channel after reaching the top of the base 41.

[0048] In this embodiment, when the water flow carries impurities through the filter assembly 1, the impurities are intercepted by the filter line 12, and under the action of the water flow and the cleaner 3, they gradually accumulate near the downstream mounting frame 2 and fall into the lifting box 42 with the opening facing the side of the filter assembly 1. At this time, the lifting box 42 is located at the bottom of the base 41. When a certain amount of impurities accumulate in the lifting box 42, the second driving unit 43 starts to work, driving the lifting box 42 to move upward in the vertical direction, and the shovel teeth 421 at the bottom shovel the impurities and move up with the lifting box 42. After the lifting box 42 rises to the top of the base 41, the second driving unit 43 continues to work, causing the lifting box 42 to flip to the outside of the drain, and the impurities in the lifting box 42 are dumped to the outside of the drain, completing the discharge of the impurities. Then the second driving unit 43 restores the lifting box 42 to its original position for the next impurity collection and discharge operation. This embodiment can automatically collect filtered impurities and discharge them to the outside of the drain through the collecting component 4, which solves the problem that the prior art may lack effective means to discharge impurities, resulting in continuous accumulation of impurities in the drain and affecting normal operation, greatly improving the efficiency of impurity cleaning and keeping the drain unobstructed; the base 41 of the collecting component 4 is fixedly connected to the mounting frame 2 through the connecting block 411, and the mounting position is always maintained downstream of the filtering component 1, so as to facilitate the collection of impurities accumulated downstream.

[0049] In order to achieve the purpose that the lifting box 42 can be transformed into a flipping motion after vertically translating to the top of the base 41, the following features are specifically set:

[0050] A second shaft 422 (such as a second shaft 422 extending horizontally along the length direction of the drainage channel) is disposed on the top of one side of the lifting box 42 that is attached to the base 41. Figure 6 and Figure 8 As shown in the figure, a positioning hook sleeve 412 parallel to the second shaft rod 422 is provided at the top of one side of the base 41 that is in contact with the lifting box 42. The positioning hook sleeve 412 is located directly above the second shaft rod 422 and is opened downward. The inner diameter of the positioning hook sleeve 412 is the same as the diameter of the second shaft rod 422. A limiting rod 423 is provided on the side wall of the lifting box 42. The axis of the limiting rod 423 is parallel to the axis of the second shaft rod 422. The limiting rod 423 is inserted into the second limiting hole 413 provided on the side wall of the base 41 (combined with Fig.10 and Fig.11 ), the width of the second limiting hole 413 is the same as the diameter of the limiting rod 423, and the second limiting hole 413 extends in the vertical direction; the top of the second limiting hole 413 is connected to the arc-shaped limiting hole 414, and after the second shaft rod 422 moves up to fit the positioning hook sleeve 412, the limiting rod 423 moves along the arc-shaped limiting hole 414, and the lifting box 42 flips around the second shaft rod 422 as the axis.

[0051] In this embodiment, during the impurity collection and shoveling stage, the lifting box 42 is located at the bottom of the base 41. When a certain amount of impurities accumulate in the base 41, the second driving unit 43 drives the lifting box 42 to rise in the vertical direction. During the rising process, the second shaft rod 422 of the lifting box 42 that fits the top of one side of the base 41 moves up synchronously with the lifting box 42. At the same time, the limiting rod 423 on the side wall of the lifting box 42 moves upward in the second limiting hole 413 extending in the vertical direction of the side wall of the base 41. Since the width of the second limiting hole 413 is the same as the diameter of the limiting rod 423, this ensures that the lifting box 42 maintains stable vertical translation during the rising process. When the lifting box 42 rises to the top of the base 41, the second shaft rod 422 moves up to fit the positioning hook 412. At this time, the limiting rod 423 moves to the top of the second limiting hole 413 and enters the arc-shaped limiting hole 414. As the second driving unit 43 continues to act, the limiting rod 423 moves along the arc limiting hole 414. Since the second shaft 422 is limited by the positioning hook 412, the lifting box 42 flips around the second shaft 422 as the axis, and the impurities in the lifting box 42 are dumped to the outside of the drainage channel. After the impurities are discharged, the second driving unit 43 acts in the reverse direction, so that the lifting box 42 returns to its original position along the opposite path, so as to carry out the next impurity collection and discharge operation. In this embodiment, through the cooperation between the second shaft 422 and the positioning hook 412, and the limiting rod 423 and the second limiting hole 413 and its arc limiting hole 414, the lifting box 42 can accurately realize the flipping motion conversion after vertical translation to the top of the base 41, ensuring the stability and reliability of the impurity discharge process.

[0052] In order to achieve the purpose that the second driving unit 43 can drive the second shaft 422 of the lifting box 42 to move in the second limiting hole 413 and the arc-shaped limiting hole 414, the following features are specifically set:

[0053] The second driving unit 43 includes a lifting block 431 slidably mounted on the outside of the base 41, and a second conveyor belt 432 driving the lifting block 431 to reciprocate in the vertical direction. A translation block 433 (such as Figure 6 As shown), the translation block 433 moves in a horizontal direction perpendicular to the length direction of the second limiting hole 413, and the limiting rod 423 is inserted into the positioning socket 434 set on the translation block 433.

[0054] In this embodiment, when impurity collection is required, the second conveyor belt 432 starts working and drives the lifting block 431 to move upward in the vertical direction. The translation block 433 slidably installed on the upper side of the lifting block 431 also rises during the lifting process of the lifting block 431. Since the limit rod 423 of the lifting box 42 is inserted into the positioning socket 434 set on the translation block 433, when the second conveyor belt 432 drives the lifting block 431 to rise, it can drive the limit rod 423 of the lifting box 42 to move in the second limit hole 413 extending in the vertical direction of the side wall of the base 41, so as to realize the lifting box 42 from the bottom to the top of the base 41. The driving of the impurity collection and shoveling stage is completed. When the lifting box 42 rises to the top of the base 41, after the second shaft rod 422 fits the positioning hook 412, the second conveyor belt 432 continues to drive the lifting block 431 to rise a short distance, so that the limit rod 423 enters the arc-shaped limit hole 414. At this time, the translation block 433 remains connected to the limit rod 423. When the limit rod 423 moves in the arc-shaped limit hole 414, the change in the horizontal position will drive the translation block 433 relative to the lifting block 431, ensuring that the limit rod 423 moves along the arc-shaped limit hole 414. Since the second shaft rod 422 is limited by the positioning hook 412, the lifting box 42 is flipped around the second shaft rod 422 as the axis, and the impurities in the lifting box 42 are dumped to the outside of the drainage channel. After the impurities are discharged, the second conveyor belt 432 drives the lifting block 431 to descend to the initial position in the vertical direction to carry out the next impurity collection and discharge operation. The lifting block 431 and the second conveyor belt 432 of this technical solution are mainly responsible for bearing the gravity and driving force during the lifting process, and the translation block 433 is responsible for connecting and assisting in adjusting the position. Compared with some existing driving technologies with complex structures and uneven force, this design reduces the load of a single component, reduces the risk of equipment failure caused by force problems, and improves the reliability and service life of the equipment.

[0055] In order to ensure that the second conveyor belt 432 can drive the lifting block 431 to reciprocate in the vertical direction, the following features are specifically set:

[0056] The rotation axis of the second conveyor belt 432 is parallel to the axis of the second shaft rod 422. A driving column 435 is fixedly installed on the second conveyor belt 432. The axis of the driving column 435 is parallel to the axis of the second shaft rod 422. The second conveyor belt 432 drives the driving column 435 to reciprocate. The driving column 435 is inserted into the third limiting hole 436 set at the bottom of the lifting block 431, and the third limiting hole 436 extends along the moving direction of the translation block 433.

[0057] In this embodiment, when the lifting block 431 needs to be driven to move, the second conveyor belt 432 is started. The second conveyor belt 432 can be a chain conveyor belt. One of the links of the second conveyor belt 432 drives the driving column 435 to start cyclic movement. During the movement, the driving column 435 cooperates with the third limiting hole 436 to push the lifting block 431 to move downward in the vertical direction. During the descent of the lifting block 431, the translation block 433 slidably connected thereto also descends, and the driving column 435 can change its position in the third limiting hole 436.

[0058] In order to ensure that no matter the filter assembly 1 is tilted to any angle, the impurities filtered by the filter assembly 1 can enter the lifting box 42 under the action of the water flow or the cleaner 3, the following features are specifically set:

[0059] A flexible screen 416 (such as Figure 6 As shown), the downstream end of the mounting frame 11 is provided with a plurality of hooks 113 (as shown Figure 3 As shown), the hook 113 is connected to the side of the flexible blocking net 416 away from the base 41.

[0060] In this embodiment, the impurities will move downstream along the filter line 12 under the action of gravity, water flow and the scraper 31 of the cleaner 3. At this time, the flexible screen 416 set on the side of the base 41 facing the filter component 1 plays a role. It intercepts the impurities moving downstream like a bag. Because the flexible screen 416 has a certain flexibility, no matter how much the filter component 1 is tilted, it can deform adaptively according to the actual situation and always maintain effective interception of impurities. The impurities intercepted by the flexible screen 416 will gradually converge to the lifting box 42 in the base 41 along the shape of the screen and the push of the water flow. The installation frame 11 is located at a plurality of hooks 113 set at the downstream end, which are connected to the side of the flexible screen 416 away from the base 41, ensuring that the position of the flexible screen 416 is relatively stable and will not be greatly displaced due to the impact of water flow or the accumulation of impurities, ensuring that the impurities can be smoothly guided into the lifting box 42, and the impurities can be effectively collected.

[0061] Working principle: The staff adjusts the inclination angle of the filter assembly 1 according to the actual width of the drain channel to adapt to drain channels of different widths. The two mounting frames 2 are respectively fitted to the side walls of the drain channel, and the sliding frame 23 on the sliding mounting frame 2 is moved in the vertical direction to fit the top of the side wall of the drain channel, and then the mounting frame 2 is fixed on the side walls of the drain channel of different depths by screwing screws into the first screw hole 22 and the second screw hole 231, thereby completing the installation of the entire device. The water flows in the drain channel, and passes through the inclined filter assembly 1. Impurities in the water, such as plastic bags, branches or leaves, can be intercepted by the filter lines 12 extending horizontally and distributed vertically at equal intervals in the installation frame 11, and the water continues to flow through the gaps between the filter lines 12. The cleaner 3 on the filter assembly 1 cleans the filter lines 12 that intercept impurities to prevent the filter lines 12 from being blocked and affecting the filtering effect. The cleaned impurities and the impurities directly intercepted by the filter lines 12 are collected by the collection assembly 4 located on the side of the downstream mounting frame 2 facing the water flow direction under the action of the water flow, which is convenient for subsequent centralized processing.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
