Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and more specifically, to a sediment processing device for water conservancy engineering. Background Art

[0002] A canal is a type of water conservancy project, mainly used for farmland irrigation, and it introduces water from rivers to farmland through "ditches" dug on the ground; these artificial waterways are divided into main canals and branch canals, usually built with stone or cement to effectively guide and distribute water resources; the gates in the canals are an important part of water conservancy projects, which can be used to intercept water flow, control water level, regulate flow, and handle sediment and floating objects; However, the gates in the canal have the following shortcomings in the process of treating sediment: when the canal gates fall, the sediment is intercepted and concentrated at the front end of the gates. At this time, an external sand pump is used to pump out the sediment in the canal, and the sediment is deposited at the bottom of the canal. When pumping, a large amount of water is easily pumped out, reducing the separation effect of sediment treatment. At the same time, when the sand pump is pumping sediment, some suspended matter such as plastic bags are easily sucked into the sand pump, causing the sand pump to be blocked and run idle and damaged. In addition, some sediment is deposited at the bottom of the canal. During the lifting process of the canal gate, the sediment will be discharged with the flow of water, reducing the effect of effective collection and treatment of sediment. Summary of the invention

[0009] The beneficial effects of the present invention are: 1.

The lifting and lowering of the lifting plate can drive the grid plate and the rotating plate mechanism to perform synchronous vertical lifting and lowering, thereby intercepting the water flow in the canal.

When the sediment accumulates to a certain amount, the electric push rod is started to retract and the connecting column is pulled up. At this time, the connecting column drives the front end of the support plate to lift up, and the rear end of the support plate rotates around the connecting shaft, so that the support plate forms an inclined state with the front end tilted upward. The side baffles on both sides prevent the sediment from leaking out, and the lifting plate drives the lifting to remove the sediment from the canal. During the lifting process, water is discharged from the gap between the interception bottom plate and the support plate to separate water and sediment, thereby improving the effect of treating sediment in the canal; 3. The external sand pump is connected to the connecting pipe sleeve on the top of the filter box. When the sand pump is running, negative pressure can be generated inside the filter box, so that the silt is pumped into the filter box from the sand inlet frame plate and the connecting pipe, and then pumped into the sand pump through the connecting pipe sleeve. The silt that enters the filter box comes into contact with the sand filter plate, and the silt can continue to move upward through the sand filter plate, while the plastic bag carried in the silt is intercepted inside the filter box to prevent the plastic bag from being sucked into the sand pump along with the silt, causing damage to the sand pump. 4. When working inside the filter box, elastic force is applied to both ends of the stop bar through the sliding blocks and spring rods on both sides, so that the stop bar can contact the lower end of the rotating door panel, thereby improving the firmness of the rotating door panel installed on the rear end of the filter box, thereby improving the sealing effect inside the filter box, avoiding air leakage during the extraction of sediment, and reducing the extraction efficiency of sediment. After the extraction is completed, the stop bar is moved downward by toggling it to separate from the lower end of the rotating door panel. At this time, the rotating door panel can be flipped up at the rear end of the filter box to facilitate the cleaning and removal of impurities in the plastic bag collected inside the filter box.

At the same time, the side fixing plates C on both sides are inclined at an angle, which is set according to the width and inclination angle of the inner part of the water channel, so as to improve the tightness of the side fixing plates C against the inner sides of the water channel, and improve the sealing of the gate mechanism F in the water channel to intercept the water flow; The gate mechanism F includes a lifting slider f3, a lifting plate f8, a fixed column f6, and a collecting mechanism f1. The lifting slider f3 is welded to the middle of the rear end of the lifting plate f8. The lower end of the worm G is passed through the middle of the rear end of the lifting slider f3 with a clearance fit and is threaded. The lower end of the guide column X is passed through the middle of the rear end of the lifting slider f3 with a clearance fit. The outer edge of the lifting plate f8 is slidably mounted on the inner side of the fixed column f6, and the upper end surface of the fixed column f6 is welded to the bottom of the support frame K. The collecting mechanism f1 is arranged at the bottom of the lifting plate f8. The bottom of the fixed column f6 is welded to the upper end of the side fixing plate C, and the side fixing plate C is located outside the collecting mechanism f1. There are two fixing columns f6, which are respectively located on the left and right edges of the lifting plate f8, and the fixing columns f6 on both sides are respectively welded and fixed to the two ends of the bottom of the support frame K. The fixing columns f6 on both sides are fixedly installed on both sides of the canal, so that the support frame K is supported at the upper end of the middle part of the canal, and the fixing columns f6 on both sides can guide the two sides of the edge during the lifting process of the lifting plate f8, thereby improving the stability of the lifting plate f8 during the lifting process.

[0021] The collecting mechanism f1 includes a rotating plate mechanism f11, a grid plate f18, and an extracting mechanism f14. The upper end of the rotating plate mechanism f11 is mounted on the front end surface of the lifting plate f8. The rotating plate mechanism f11 is mounted on the bottom of the grid plate f18, and the bottom of the grid plate f18 is welded to the bottom of the lifting plate f8. The lower end of the extracting mechanism f14 is located above the rotating plate mechanism f11, and the upper end of the extracting mechanism f14 is fixedly mounted on the back of the lifting plate f8. The grid plate f18 is connected between the rotating plate mechanism f11 and the lifting plate f8. The lifting of the lifting plate f8 can drive the grid plate f18 and the rotating plate mechanism f11 to perform synchronous vertical lifting and lowering, thereby intercepting the water flow in the canal. In addition, the grid plate f18 can intercept larger impurities such as plastic bags.

[0022] The rotating plate mechanism f11 includes an electric push rod 1q, a connecting column 1v, an intercepting bottom plate 1g, a side baffle 1c, a connecting shaft 1z, and a support plate 1x. The upper end of the electric push rod 1q is axially connected to the front end surface of the lifting plate f8, and the lower end of the electric push rod 1q is axially connected to the upper end of the connecting column 1v. The lower end of the connecting column 1v is welded to the front of the upper surface of the support plate 1x, and the rear end of the support plate 1x is connected to the inside of the intercepting bottom plate 1g through the connecting shaft 1z. The side baffle 1c is welded to the outside of the intercepting bottom plate 1g, and the upper end of the intercepting bottom plate 1g is welded to the lower end of the grid plate f18. The support plate 1x is located on the inner side of the side baffle 1c, and the lower end of the extraction mechanism f14 is located above the support plate 1x. There are two electric push rods 1q and two connecting columns 1v, which are symmetrically connected between the support plate 1x and the lifting plate f8. The two electric push rods 1q operate synchronously to pull the front end of the support plate 1x upward, and under the connection of the connecting shaft 1z, the rear end of the support plate 1x rotates around the connecting shaft 1z, so that the support plate 1x forms an inclined state with the front end tilted upward, thereby hooking the mud and sand deposited between the support plate 1x and the intercepting bottom plate 1g, and combining with the side baffles 1c on both sides to prevent the mud and sand from leaking out, and the lifting is driven by the lifting plate f8 to move the mud and sand out of the canal. During the lifting process, water is discharged from the gap at the connection between the intercepting bottom plate 1g and the support plate 1x, so as to achieve the separation of water and mud and sand, thereby improving the effect of treating the mud and sand in the canal. The specific usage and function of this embodiment are as follows: In the present invention, when the gate mechanism F is installed inside the water channel, it is fixed on both sides of the upper end of the water channel through the fixing columns f6 on both sides. At the same time, the side fixing plates C on both sides are inclined and set according to the width and the inclination angle inside the water channel. This can improve the tightness of the side fixing plates C against the two sides inside the water channel, and improve the sealing of the gate mechanism F inside the water channel to intercept the water flow, so that the gate mechanism F is firmly installed inside the water channel. The worm G is driven to rotate by the start of the motor D, and the lifting slider f3 can be lifted and driven under the vertical guidance of the guide column X, thereby driving the lifting plate f8 to lift and lower. The lifting of the lifting plate f8 can drive the grid plate f18 and the rotating plate mechanism f11 to perform synchronous vertical lifting and lowering, thereby intercepting the water flow in the water channel, and the grid plate f18 can be used to intercept larger impurities such as For example, when a plastic bag is used to intercept, the silt is blocked by the interception bottom plate 1g and deposited on the upper surface of the pallet 1x to collect the silt. When the silt accumulates to a certain amount, the electric push rod 1q is started to retract and the connecting column 1v is pulled up. At this time, the connecting column 1v drives the front end of the pallet 1x to lift up, and under the connection of the connecting shaft 1z, the rear end of the pallet 1x rotates around the connecting shaft 1z, so that the pallet 1x forms an inclined state with the front end tilted upward, thereby hooking the silt deposited between the pallet 1x and the interception bottom plate 1g, and combining with the side baffles 1c on both sides to prevent the silt from leaking out, and driving the lifting through the lifting plate f8, the silt is removed from the canal. During the lifting process, water is discharged from the gap between the interception bottom plate 1g and the pallet 1x to achieve the separation of water and silt, thereby improving the effect of treating the silt in the canal. Example

[0023] As attached Figure 6 To Attachment Figure 8 As shown: The extraction mechanism f14 includes a filter mechanism 4x, a connecting pipe 4g, and a sand inlet frame plate 4k. The filter mechanism 4x is fixedly installed on the back of the lifting plate f8. The lower end of the filter mechanism 4x is welded and connected to the upper end of the connecting pipe 4g. The lower end of the connecting pipe 4g is connected to the upper end of the sand inlet frame plate 4k, and the sand inlet frame plate 4k is located above the supporting plate 1x. The filtering mechanism 4x and the connecting pipe 4g are each provided with two, and are installed symmetrically on the left and right. At the same time, the lower ends of the two connecting pipes 4g are through-connected with the two sides of the upper end of the sand inlet frame plate 4k. The sediment can be diverted and extracted through the filtering mechanism 4x and the connecting pipe 4g on both sides to avoid blockage in the sediment extraction process. The sand inlet frame plate 4k is a long strip structure, and at the same time, the lower end of the sand inlet frame plate 4k is an inclined surface structure with a high front end and a low rear end, which avoids the collision of the lower end of the sand inlet frame plate 4k when the support plate 1x rotates, thereby improving the stability of the sand inlet frame plate 4k installed above the support plate 1x, so that the sediment can stably enter the connecting pipe 4g from the support plate 1x for extraction.

[0024] The filtering mechanism 4x includes a connecting pipe sleeve x3, a filter box x9, a sand filter plate x5, and a closing mechanism x7. The connecting pipe sleeve x3 is fixedly installed at the middle end of the top of the filter box x9, and a sand filter plate x5 is installed at the middle end of the filter box x9. The bottom of the filter box x9 is welded to the upper end of the connecting pipe 4g and is connected through. The closing mechanism x7 is installed on the rear surface of the filter box x9, and the front end of the filter box x9 is fixedly installed on the back of the lifting plate f8. The sand filter plate x5 has an inverted "V"-shaped structure, and the width and length of the sand filter plate x5 match the internal dimensions of the filter box x9, so that the sand filter plate x5 is tightly and firmly installed inside the filter box x9. At the same time, the inverted "V"-shaped sand filter plate x5 can improve the effect of comprehensive and dispersed filtration of the sediment entering the filter box x9, and improve the interception of plastic bags carried in the sediment inside the filter box x9, so as to prevent the plastic bags from being sucked into the sand pump along with the sediment, causing damage to the sand pump.

[0025] The closing mechanism x7 includes a rotating door panel x77, a sliding block x79, a stop bar x75, and a spring rod x72.

The edge of the stop bar x75 is provided with a sliding block x79, and the sliding block x79 is slidably installed inside the side of the filter box x9. The spring rod x72 is fixedly installed inside the side of the filter box x9, and the upper end of the spring rod x72 is reduced and passes through the inside of the sliding block x79. There are two sliding blocks x79 and spring rods x72, and they are symmetrically installed on the left and right sides of the filter box x9. At the same time, the two sliding blocks x79 are fixedly installed on the left and right ends of the stop bar x75. The sliding blocks x79 and spring rods x72 on both sides apply elastic force to the two ends of the stop bar x75, so that the stop bar x75 can be in contact with the lower end of the rotating door panel x77, thereby improving the firmness of the rotating door panel x77 installed on the rear end of the filter box x9, thereby improving the sealing effect inside the filter box x9, avoiding air leakage during the extraction of sediment, and reducing the extraction efficiency of sediment. After the extraction is completed, the stop bar x75 is moved downward by toggling the stop bar x75 to separate from the lower end of the rotating door panel x77. At this time, the rotating door panel x77 can be flipped up at the rear end of the filter box x9, which is convenient for cleaning and removing the plastic bag impurities collected in the filter box x9. The specific usage and function of this embodiment are as follows: In the present invention, after the silt is collected on the rotating plate mechanism f11 and lifted, it is connected to the connecting pipe sleeve x3 on the top of the filter box x9 through an external sand pump. When the sand pump is running, a negative pressure can be generated inside the filter box x9, so that the silt is sucked into the filter box x9 from the sand inlet frame plate 4k and the connecting pipe 4g, and then sucked into the sand pump through the connecting pipe sleeve x3. The silt that enters the filter box x9 comes into contact with the sand filter plate x5, and the silt can continue to move upward through the sand filter plate x5, while the plastic bag carried in the silt is intercepted inside the filter box x9 to prevent the plastic bag from being sucked into the sand pump along with the silt, causing damage to the sand pump, and the filter box When working inside x9, elastic force is applied to both ends of the stop bar x75 through the sliding blocks x79 and the spring rod x72 on both sides, so that the stop bar x75 can resist the lower end of the rotating door panel x77, thereby improving the firmness of the rotating door panel x77 installed on the rear end of the filter box x9, thereby improving the sealing effect inside the filter box x9, avoiding air leakage during the extraction of sediment, and reducing the extraction efficiency of sediment. After the extraction is completed, the stop bar x75 is moved downward by toggling the stop bar x75 to separate from the lower end of the rotating door panel x77. At this time, the rotating door panel x77 can be flipped up at the rear end of the filter box x9, which is convenient for cleaning and removing the impurities in the plastic bag collected inside the filter box x9.
