Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water diversion pipeline for water conservancy project construction. Background Art

[0002] A water conservancy project refers to an engineering construction project carried out to effectively utilize water resources and ensure people's domestic water supply, farmland irrigation, industrial production and other needs. In water conservancy projects, water diversion devices are usually used, which refer to facilities that bring water from the water source into the water conservancy project system.

[0003] Chinese patent "A water diversion device for water conservancy project construction" authorization announcement number "CN216199184U" This water diversion device for water conservancy project construction is used in conjunction with a rotating disk, a rotating pin, a crank, a reciprocating rod, a brush plate and a brush, so that the rotating disk drives the rotating pin to rotate, and the rotating pin drives the brush plate to move back and forth left and right through the crank and the reciprocating rod. The brush pushes the debris blocked on the filter net to the right out of the discharge chute, thereby further reducing the probability of filter net clogging, further improving the smoothness of water pumping in the suction pipe, and facilitating maintenance by staff.

[0004] In the above scheme, a brush is used to clean the impurities blocked on the filter screen, but the impurities that can be cleaned by the brush are limited. When the blocked impurities are large, the cleaning pressure of the brush will increase, causing the brush to deform, thereby affecting the cleaning effect of the brush.

[0005] Therefore, a water diversion pipeline for water conservancy project construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a water diversion pipe for water conservancy project construction in order to solve the above-mentioned problem, thereby improving the problem that the impurities cleaned by the brush are limited. When there are more blocked impurities, the cleaning pressure of the brush will increase, causing the brush to deform, thereby affecting the cleaning effect of the brush.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a water diversion pipeline for water conservancy project construction, comprising: a first pipeline, a filter box is installed at the top of the first pipeline, a second pipeline is installed at the top of the filter box, the inner wall of the filter box is fixedly connected with a filter plate, the surface of the filter plate is provided with filter holes distributed in a rectangular row, and the top of the filter plate is provided with a cleaning mechanism; wherein the cleaning mechanism comprises a reciprocating screw rod rotatably connected to the inner wall of the filter box, one side of the filter box is fixedly connected to a motor, one end of the reciprocating screw rod passes through the filter box and is fixedly connected to the output shaft of the motor, a moving rod is provided on the surface of the reciprocating screw rod, a cleaning brush is fixedly connected to one side of the moving rod, and round rods distributed in equal rows are fixedly connected on both sides of the cleaning brush, a cylinder is slidably connected to the surface of the round rod, a spring is fixedly connected between the bottom end of the round rod and the top end of the cylinder, and a cleaning component is provided on the surface of the filter plate.

[0008] Preferably, the cleaning assembly comprises a moving plate slidably connected to the bottom end of the filter plate, the bottom end of the moving rod passes through the filter plate and is fixedly connected to the top end of the moving plate, and scrapers are fixedly connected to both sides of the moving plate. Under the action of the moving plate and the scraper, the pushed impurities are scraped off to prevent the impurities from gathering under the filter plate and entering the filter holes again, thereby improving the cleaning effect of the filter holes.

[0009] Preferably, cleaning rods distributed in equal rows are fixedly connected to both sides of the inner wall of the filter hole, and a cleaning block is fixedly connected to the other end of the cleaning rod. The cleaning block is shaped like a flat-topped cone. When the cleaning brush moves, under the action of the cleaning rod and the cleaning block, it is helpful to scrape off the impurities adhered to the cleaning brush, avoiding the cleaning brush from bringing the impurities out to the top of the filter plate when moving, thereby ensuring the filtering effect of the filter plate and the filter hole.

[0010] Preferably, the bottom end of the cylinder is curved into a spherical shape, and the other end of the cleaning block is curved into a spherical shape, which is conducive to better squeezing the cylinder to move upward.

[0011] Preferably, the top end of the scraper is in contact with the bottom end of the filter plate, and the vertical cross section of the scraper is a right triangle, which is conducive to better scraping off impurities under the action of the inclined surface.

[0012] Preferably, the inner wall of the filter box is fixedly connected with two limit rods, the top end of the cleaning brush and the bottom end of the movable plate are fixedly connected with limit blocks, and the inner wall of the limit block is slidably connected with the surface of the corresponding limit rod, thereby ensuring the stability of the movement of the cleaning brush and the movable plate.

[0013] Preferably, both sides of the filter box are fixedly connected with a collecting box, and the bottom of the collecting box forms an angle with the horizontal plane. The arrangement of two collecting boxes is conducive to better collection of impurities when the cleaning brush and the scraper move back and forth.

[0014] Preferably, a moving groove matching the moving rod is provided at the top of the filter plate, and the width of the moving groove is smaller than the width of the filter hole, so as to prevent impurities larger than the filter hole from flowing out of the moving groove.

At the same time, under the action of the moving plate and the scraper, the pushed impurities are scraped off to prevent the impurities from gathering under the filter plate and entering the filter hole again, thereby improving the cleaning effect of the filter hole;

[0017] 2. When the cleaning brush moves, the cleaning rod and the cleaning block can help scrape off the impurities adhering to the cleaning brush, avoiding the impurities being brought to the top of the filter plate when the cleaning brush moves, thereby ensuring the filtering effect of the filter plate and the filter holes.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a water diversion pipeline for water conservancy project construction includes: a first pipeline 1, a filter box 2 is installed at the top of the first pipeline 1, a second pipeline 3 is installed at the top of the filter box 2, a filter plate 4 is fixedly connected to the inner wall of the filter box 2, filter holes 5 distributed in rectangular rows are opened on the surface of the filter plate 4, and a cleaning mechanism 6 is arranged on the top of the filter plate 4; wherein the cleaning mechanism 6 includes a reciprocating screw 601 rotatably connected to the inner wall of the filter box 2, a motor 602 is fixedly connected to one side of the filter box 2, one end of the reciprocating screw 601 passes through the filter box 2 and is fixedly connected to the output shaft of the motor 602, a moving rod 603 is arranged on the surface of the reciprocating screw 601, a cleaning brush 604 is fixedly connected to one side of the moving rod 603, round rods 605 distributed in equal rows are fixedly connected to both sides of the cleaning brush 604, a cylinder 606 is slidably connected to the surface of the round rod 605, a spring 607 is fixedly connected between the bottom end of the round rod 605 and the top of the cylinder 606, and a cleaning component 608 is arranged on the surface of the filter plate 4.

[0026] When using the device, the second pipe 3 is installed with the water diversion equipment through the flange. When the water diversion operation is performed, the water flows through the first pipe 1, the filter box 2, and the second pipe 3 in sequence. The filter plate 4 intercepts impurities in the water flow, and the water flows out through the filter hole 5. At this time, the impurities will gather under the filter plate 4 and in the filter hole 5, and the cleaning mechanism 6 is started to clean the impurities.

[0027] During cleaning, the controller is used to start the motor 602 to drive the reciprocating screw 601 to rotate. The reciprocating screw is in the form of two threaded grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion, and the reciprocating screw 601 is made of stainless steel, so that the moving rod 603 drives the cleaning brush 604 and the moving plate 6081 to move back and forth. When the cleaning brush 604 moves, it will drive the round rod 605 and the cylinder 606 to move synchronously. The number of cylinders 606 is the same as the number of longitudinal filter holes 5, and the positions correspond one to one. When the cylinder 606 moves to the top of the filter hole 5, under the action of the spring 607, the cylinder 606 will enter the filter hole 5 and push the blocked impurities in the filter hole 5 to the bottom of the filter hole 5.

[0028] like Figure 2 , Figure 3, Figure 4 and Figure 5 As shown, the cleaning assembly 608 includes a movable plate 6081 slidably connected to the bottom end of the filter plate 4, the bottom end of the movable rod 603 penetrates the filter plate 4 and is fixedly connected to the top of the movable plate 6081, and the two sides of the movable plate 6081 are fixedly connected with scrapers 6082. Both sides of the inner wall of the filter hole 5 are fixedly connected with cleaning rods 6083 distributed in equal rows, and the other end of the cleaning rod 6083 is fixedly connected with a cleaning block 6084, and the shape of the cleaning block 6084 is a flat-topped cone. The bottom end of the cylinder 606 is curved into a spherical shape, and the other end of the cleaning block 6084 is curved into a spherical shape. The top of the scraper 6082 is in contact with the bottom end of the filter plate 4, and the vertical section of the scraper 6082 is a right triangle.

[0029] When the cylinder 606 pushes the impurities blocked in the filter hole 5 downward, the movable plate 6081 drives the scraper 6082 to move to the bottom of the corresponding filter hole 5, and the scraper 6082 will scrape away the pushed impurities and the impurities under the filter plate 4, and the cleaning brush 604 drives the cylinder 606 to continue to move, and under the action of multiple cleaning blocks 6084, the cylinder 606 will be squeezed to move upward, and the spring 607 is compressed to make the bottom end of the cylinder 606 fit with the top of the filter plate 4 again. At this time, the cleaning brush 604 enters the filter hole 5 to clean the impurities in the filter hole 5 for the second time. At the same time, the cleaning brush 604 continues to move, the cylinder 606 will enter the filter hole 5 again, and during the movement of the cleaning brush 604, the cleaning rod 6083 and the cleaning block 6084 will be inserted into the bristles of the cleaning brush 604 to clean the impurities on the bristles.

[0030] like Figure 3 and Figure 4 As shown, two limit rods 6085 are fixedly connected to the inner wall of the filter box 2, the top of the cleaning brush 604 and the bottom of the movable plate 6081 are fixedly connected to the limit block 6086, and the inner wall of the limit block 6086 is slidably connected to the surface of the corresponding limit rod 6085. When the cleaning brush 604 and the movable plate 6081 move, the limit block 6086 will be driven to move synchronously, and at this time, the inner wall of the limit block 6086 will slide along the surface of the limit rod 6085.

[0031] like Figure 2 As shown, both sides of the filter box 2 are fixedly connected with a collecting box 609, and an angle is formed between the bottom end of the collecting box 609 and the horizontal plane. When the cleaning brush 604 and the scraper 6082 move back and forth, they can push impurities into the collecting box 609, and when the impurities enter the collecting box 609, they will slide to the lower part of the collecting box 609.

[0032] like Figure 2As shown, the top of the filter plate 4 is provided with a moving groove 6087 matching the moving rod 603, and the width of the moving groove 6087 is smaller than the width of the filter hole 5. When the moving rod 603 moves, it moves along the inner wall of the moving groove 6087, and the width of the moving groove 6087 is small, so as to prevent impurities larger than the filter hole 5 from flowing out of the moving groove 6087.

[0033] When the utility model is in use, when cleaning the intercepted impurities, the motor 602 is started to drive the reciprocating screw rod 601 to rotate, so that the moving rod 603 drives the cleaning brush 604 and the moving plate 6081 to move back and forth. When the cleaning brush 604 moves, it will drive the round rod 605 and the cylinder 606 to move synchronously. When the cylinder 606 moves to the top of the filter hole 5, under the action of the spring 607, the cylinder 606 will enter the filter hole 5 and push the blocked impurities in the filter hole 5 to the bottom of the filter hole 5. At the same time, the moving plate 6081 drives the scraper 6082 to move to the bottom of the corresponding filter hole 5. The scraper 6082 will scrape away the pushed impurities and the impurities under the filter plate 4. At this time, the cleaning brush 604 drives the cylinder 606 to continue moving , under the action of multiple cleaning blocks 6084, the cylinder 606 will be squeezed to move upward, and the spring 607 will be compressed, so that the bottom end of the cylinder 606 will fit with the top end of the filter plate 4 again. At this time, the cleaning brush 604 enters the filter hole 5 to clean the impurities in the filter hole 5 for the second time. The cleaning brush 604 continues to move, and the cylinder 606 will enter the filter hole 5 again. During the movement of the cleaning brush 604, the cleaning rod 6083 and the cleaning block 6084 will be inserted into the bristles of the cleaning brush 604 to clean the impurities on the bristles. During the movement of the cleaning brush 604 and the cylinder 606, the filter hole 5 is cleaned. During the movement of the scraper 6082, the impurities pushed out of the filter hole 5 and the impurities under the filter plate 4 will be pushed into the collection box 609.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
