Description

Technical Field

[0001] The invention relates to the technical field of sewer pipe cleaning, in particular to a silt removal device with a cleaning function. Background Art

[0002] At present, in order to ensure normal drainage in the city, the sewer pipes in the city need to be dredged at regular intervals. Nowadays, there are many dredging devices specifically used to clean and dredge sediments, sludge and garbage in urban sewer networks, sewage treatment systems and drainage systems.

[0003] For example, the patents "Publication No. CN116397757A A Drainage Pipeline Desilting Device" and "Publication No. CN109629659A A Municipal Drainage Pipeline Desilting Device and Desilting Process" both disclose a device for desilting sewer pipes. However, existing desilting devices are usually unable to select whether to extract the sludge from the sewer pipe or to flush the sludge from the sewer pipe by high-pressure water flow according to the state of the sludge in the sewer pipe, which is not conducive to improving the desilting efficiency. At the same time, if there are a lot of impurities such as hair in the sludge, the desilting device is prone to blockage. Finally, when the current desilting device flushes the inner wall of the sewer pipe with a high-pressure water flow, if the sewer pipe is thin or has been in use for a long time, the sewer pipe is easily broken when flushed by the high-pressure water flow due to excessive water pressure used during flushing. Summary of the invention

[0004] The purpose of the present invention is to provide a silt removal device with a cleaning function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: Compared with the prior art, the beneficial effects of the present invention are: a dredging device with a cleaning function, the dredging device comprises a working mechanism and an installation box, the working mechanism comprises a fixed pipe, a fixed sleeve and a dredging head, the fixed sleeve is arranged on the outside of the fixed pipe, the dredging head is arranged on the side end of the fixed sleeve, a dredging channel is arranged inside the dredging head, a dredging inlet pipe is arranged at one end of the dredging head away from the fixed sleeve, the fixed pipe is connected with the dredging inlet pipe through the dredging channel, a sealing assembly is arranged on the outside of one end of the dredging channel close to the dredging inlet pipe, a liquid discharge assembly is arranged on the outside of one end of the dredging channel close to the fixed pipe, a first liquid pump, a second liquid pump and a three-way pipe are arranged inside the installation box, one end of the three-way pipe is connected with the liquid inlet end of the first liquid pump through a first valve, the other end of the three-way pipe is connected with the liquid outlet end of the second liquid pump through a second valve, and the last end of the three-way pipe is connected with the fixed pipe through a hose. Compared with the prior art, the present invention has the advantages of The dredging device is provided with a sealing component and a drainage component. At the same time, a camera is provided at one end of the dredging head away from the fixed sleeve. The camera enables the staff to monitor the state of the sludge in the sewer in real time. The sealing component and the drainage component facilitate the staff to choose whether to extract the sludge from the sewer pipe or flush the sludge from the sewer pipe by high-pressure water flow according to the state of the sludge in the sewer pipe. That is, when the sewer pipe is blocked by a lot of sludge or dirt, the staff can open the first valve and then extract the sludge and dirt in the sewer pipe by the first liquid pump. When the sludge or dirt adheres to the inner wall of the sewer pipe, the staff can open the sealing component, and the fixed pipe and the silt inlet pipe are separated by the sealing component, and then the second valve is opened. Finally, the high-pressure water flow is transported into the working mechanism by the second liquid pump, and the high-pressure water flow is discharged by the drainage component to flush the inner wall of the sewer pipe, thereby achieving the dredging effect.

[0006] Furthermore, several groups of support components are arranged on both ends of the outer side of the fixed sleeve, and each group of the support components has a telescopic function. When the staff places the working mechanism into the sewer pipe, they need to adjust the length of the support component to facilitate the subsequent movement of the working mechanism in the sewer pipe.

[0007] Furthermore, the fixed sleeve is fixedly connected to the fixed pipe, and an inner gear, an outer gear and a motor are provided at one end of the fixed sleeve close to the dredging head. The dredging head is connected to the inner gear through a connecting block, and a plurality of groups of the outer gears are provided. The plurality of groups of the outer gears are evenly arranged inside the inner gear and mesh with the inner gear. The working end of the motor is connected to one of the groups of the outer gears. When the working mechanism of the present invention works in the sewer pipe, the motor continuously drives the inner gear and the dredging head to rotate through the outer gear. When the staff uses the extraction method to dredge, the dredging head can break up the silt in the sewer pipe during the rotation process for easy extraction. When the staff uses high-pressure water flow to flush the silt, the dredging head can ensure that the high-pressure water flow covers the entire dredging area during the rotation process, thereby evenly flushing every corner to avoid uncleaned dead corners. At the same time, during the rotation of the dredging head, the high-pressure water flow will exert force on the silt at different angles and directions, thereby effectively destroying the structure of the silt and improving the dredging effect.

[0008] Furthermore, a cleaning component is provided on the outside of one end of the dredging head close to the fixed sleeve, and the cleaning component has a retraction function. When the sewer pipe is dredged by flushing, the cleaning component will be unfolded from the side end of the dredging head. The cleaning component can reduce the pressure applied by the high-pressure water flow to the sewer pipe as much as possible on the basis of ensuring the dredging effect of the sewer pipe, thereby avoiding the rupture of thin-walled pipes or pipes with a long service life due to excessive flushing pressure.

[0009] Furthermore, the sealing assembly includes a sealing groove and a sealing plate. The sealing grooves are provided with two groups. The two groups of sealing grooves are relatively arranged on both sides of the silt discharge channel. A group of liquid storage tanks is provided on the side of each group of sealing grooves away from the silt inlet pipe. A group of electromagnets is provided in each group of liquid storage tanks. Hydraulic oil is provided at both ends of each group of liquid storage tanks. A group of first pressure plates is provided on the side of each group of electromagnets close to the sealing grooves. Each group of liquid storage tanks is connected to a group of sealing grooves. A group of sealing plates is provided in each group of sealing grooves. Each group of sealing plates is movably installed in the sealing grooves through first compression springs. When the sealing assembly in the invention is not working, the two groups of sealing plates are retracted into the sealing groove, so as to prevent impurities such as hair in the sludge from getting stuck in the silt discharge channel when the staff is pumping out the sludge. When the staff needs to flush the sewer pipe with the help of high-pressure water flow, the two groups of first pressure plates can be driven by two groups of electromagnets to move away from the electromagnets. At this time, the hydraulic oil in the two groups of liquid storage tanks will enter the two groups of sealing grooves. Under the action of hydraulic pressure, the two groups of sealing plates will extend out of the sealing grooves and close. When the fixed pipe is separated from the silt inlet pipe, if the staff uses the second liquid pump to transport high-pressure water flow into the working mechanism, the high-pressure water flow will eventually spray out from the drainage assembly.

[0010] Furthermore, the cleaning assembly includes a cleaning frame, and the cleaning frame is provided with two groups, each group of the cleaning frames is connected to the dredging head through a group of rotating shafts, and each group of the cleaning frames is provided with a group of transmission grooves and a group of reset grooves on the left and right sides, one end of each group of the rotating shafts is arranged in a group of transmission grooves, and the other end of each group of the rotating shafts is arranged in a group of reset grooves, and each group of the rotating shafts at one end located in the transmission groove is provided with a transmission block, and each group of the rotating shafts at one end located in the reset groove is provided with a coil spring, and the two groups of electromagnets are provided with a group of second pressure Plates, each group of the liquid storage tanks is connected to a group of transmission grooves. The first pressure plate and the second pressure plate in the present invention are both magnetic. When the two groups of electromagnets are turned on, the two groups of second pressure plates will also move away from the electromagnets. At this time, the hydraulic oil in the two groups of liquid storage tanks will enter the two groups of transmission grooves. Under the action of hydraulic pressure, the two groups of transmission blocks will rotate with the rotating shaft and the cleaning frame, so that the cleaning frame is unfolded at the side end of the dredging head. When the silt on the inner wall of the sewer pipe is flushed, the motor will rotate with the dredging head and the two groups of unfolded cleaning frames to perform friction cleaning on the inner wall of the sewer pipe.

[0011] Furthermore, the drainage component includes a telescopic groove, a drainage channel and a movable block. The telescopic grooves are provided with two groups. The two groups of telescopic grooves are relatively arranged on both sides of the silt discharge channel. The two groups of telescopic grooves and the two groups of sealing grooves are not on the same side of the silt discharge channel. Each group of telescopic grooves is provided with a group of drainage channels at one end close to the cleaning component. Each group of telescopic grooves is provided with a group of movable blocks. Each group of movable blocks is movably installed in the telescopic groove by a second compression spring. When the drainage component in the present invention is not working, the two groups of movable blocks are located at one end of the telescopic groove close to the silt discharge channel. When the fixed pipe is separated from the silt inlet pipe, if the staff delivers high-pressure water flow to the working mechanism through the second liquid pump, the two groups of movable blocks will be pushed into the telescopic groove under the action of the hydraulic pressure. At this time, the high-pressure water flow will flow out through the drainage channel, thereby achieving the purpose of flushing and desilting.

[0012] Furthermore, each group of the movable blocks is provided with a group of piezoelectric sheets at one end close to the second compression spring, and the piezoelectric sheets are electrically connected to the second liquid pump. When the high-pressure water flow is ejected from the telescopic groove and the drainage channel, the staff can determine whether the pressure of the high-pressure water flow sprayed onto the inner wall of the sewer pipe is too large by monitoring the changes in the electrical signals on the piezoelectric sheets, so as to facilitate the staff to adjust the pressure of the high-pressure water flow delivered by the second liquid pump in real time according to needs.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the current dredging device, the present invention is provided with a sealing component and a drainage component, and a camera is provided at the end of the dredging head away from the fixed sleeve, so that the staff can monitor the state of the sludge in the sewer in real time through the camera, and the sealing component and the drainage component are convenient for the staff to choose whether to extract the sludge from the sewer pipe according to the state of the sludge in the sewer pipe, or to flush the sludge out of the sewer pipe by high-pressure water flow, so as to improve the dredging effect and the use scenario of the device. The present invention is also provided with an internal gear, an external gear and a motor, and the motor can continuously drive the internal gear and the dredging head to rotate during the dredging process of the present invention through the external gear. When the staff adopts the extraction method to dredge, the dredging head can break up the sludge in the sewer pipe during rotation for easy extraction, and at the same time, the sealing component in the dredging head The sealing component and the drainage component will ensure that the wall surface of the silt discharge channel is in a smooth state, thereby preventing impurities such as hair from existing in the silt and then getting stuck in the silt discharge channel. When the staff uses high-pressure water flow to flush the silt, the dredging head can ensure that the high-pressure water flow covers the entire dredging area during the rotation process, thereby evenly flushing every corner to avoid uncleaned dead corners. At the same time, during the rotation of the dredging head, the high-pressure water flow will exert force on the silt at different angles and directions, thereby effectively destroying the structure of the silt and improving the dredging effect. In addition, the present invention also has a cleaning component on the outside of the end of the dredging head close to the fixed sleeve. The cleaning component can reduce the pressure applied by the high-pressure water flow on the sewer pipe as much as possible on the basis of ensuring the dredging effect of the sewer pipe, thereby avoiding the rupture of thin-walled pipes or pipes that have been used for a long time due to excessive flushing pressure.

At the same time, the present invention is provided with a camera 133 at one end of the silt clearing head 13 away from the fixed sleeve 12. The camera 133 enables the staff to monitor the state of the sludge in the sewer in real time. Through the sealing component and the drainage component, it is convenient for the staff to choose to extract the sludge from the sewer pipe according to the state of the sludge in the sewer pipe, or to flush the sludge from the sewer pipe through a high-pressure water flow. That is, when the sludge or dirt blocks the sewer pipe, the staff can open the first valve, and then extract the sludge and dirt in the sewer pipe through the first liquid pump 21. When the sludge or dirt adheres to the inner wall of the sewer pipe, the staff can open the sealing component, and the fixed pipe 11 and the silt inlet pipe 132 are separated by the sealing component, and then the second valve is opened. Finally, the high-pressure water flow is transported into the working mechanism 1 through the second liquid pump 22, and the high-pressure water flow is discharged through the drainage component to flush the inner wall of the sewer pipe, thereby achieving the silt clearing effect.

[0018] like Figure 1-Figure 2 As shown, several groups of support components 14 are arranged on both ends of the outer side of the fixed sleeve 12, and each group of support components 14 has a telescopic function. When the staff places the working mechanism 1 into the sewer pipe, it is necessary to adjust the length of the support component 14 to facilitate the subsequent movement of the working mechanism 1 in the sewer pipe.

[0019] like Figure 2-Figure 4As shown, the fixed sleeve 12 is fixedly connected to the fixed pipe 11, and the end of the fixed sleeve 12 close to the dredging head 13 is provided with an internal gear 121, an external gear 122 and a motor 123. The dredging head 13 is connected to the internal gear 121 through a connecting block 136. The external gear 122 is provided with a plurality of groups, and the plurality of groups of external gears 122 are evenly arranged inside the internal gear 121 and meshed with the internal gear 121. The working end of the motor 123 is connected to one of the groups of external gears 122. When the working mechanism 1 of the present invention works in the sewer pipe, the motor 123 continuously rotates through the external gear 122. The internal gear 121 and the dredging head 13 are driven to rotate. When the staff uses extraction to dredge, the dredging head 13 can break up the silt in the sewer pipe during rotation to facilitate extraction. When the staff uses high-pressure water flow to flush the silt, the dredging head 13 can ensure that the high-pressure water flow covers the entire dredging area during rotation, thereby flushing every corner evenly to avoid uncleaned dead corners. At the same time, during the rotation of the dredging head 13, the high-pressure water flow will exert force on the silt at different angles and directions, thereby effectively destroying the structure of the silt and improving the dredging effect.

[0020] like Figure 4-Figure 8 As shown, a cleaning component is arranged on the outside of one end of the dredging head 13 close to the fixed sleeve 12, and the cleaning component has a retracting function. When the sewer pipe is dredged by flushing, the cleaning component will be unfolded from the side end of the dredging head 13. The cleaning component can reduce the pressure applied by the high-pressure water flow to the sewer pipe as much as possible on the basis of ensuring the dredging effect of the sewer pipe, thereby avoiding the rupture of thin-walled pipes or pipes with a long service life due to excessive flushing pressure.

[0021] like Figure 4-Figure 5 As shown, the sealing assembly includes a sealing groove 134 and a sealing plate 1341. There are two groups of sealing grooves 134. The two groups of sealing grooves 134 are relatively arranged on both sides of the silt discharge channel 131. A group of liquid storage tanks are arranged on the side of each group of sealing grooves 134 away from the silt inlet pipe 132. A group of electromagnets 137 are arranged in each group of liquid storage tanks. Hydraulic oil is arranged on the left and right ends of each group of liquid storage tanks. A group of first pressure plates are arranged on the side of each group of electromagnets 137 close to the sealing groove 134. Each group of liquid storage tanks is connected with a group of sealing grooves 134. A group of sealing plates 1341 are arranged in each group of sealing grooves 134. Each group of sealing plates 1341 is movably installed in the sealing groove 134 through a first compression spring and connected.

[0022] like Figure 4-Figure 8As shown, the cleaning assembly includes a cleaning frame 135, and the cleaning frame 135 is provided with two groups. Each group of cleaning frames 135 is connected to the dredging head 13 through a group of rotating shafts 1351. A group of transmission grooves 138 and a group of reset grooves are provided on the left and right sides of each group of cleaning frames 135. One end of each group of rotating shafts 1351 is arranged in a group of transmission grooves 138, and the other end of each group of rotating shafts 1351 is arranged in a group of reset grooves. A transmission block 1352 is provided at one end of each group of rotating shafts 1351 located in the transmission groove 138, and a coil spring 1353 is provided at one end of each group of rotating shafts 1351 located in the reset groove. A group of second pressure plates are provided on one side of the two groups of electromagnets 137 close to the transmission groove 138, and each group of liquid storage tanks is connected to a group of transmission grooves 138.

[0023] like Figure 4 , Fig. 9 As shown, the drainage component includes a telescopic groove 139, a drainage channel 1391 and a movable block 1392. There are two groups of telescopic grooves 139. The two groups of telescopic grooves 139 are relatively arranged on both sides of the silt discharge channel 131. The two groups of telescopic grooves 139 and the two groups of sealing grooves 134 are not on the same side of the silt discharge channel 131. Each group of telescopic grooves 139 is provided with a group of drainage channels 1391 at one end close to the cleaning component, and each group of telescopic grooves 139 is provided with a group of movable blocks 1392. Each group of movable blocks 1392 is movably installed in the telescopic groove 139 through a second compression spring.

[0024] When the sealing assembly and the drain assembly of the present invention are not in operation, the two sets of sealing plates 1341 are retracted into the sealing groove 134 (such as Figure 5 As shown in FIG. 1 ), the two sets of movable blocks 1392 are both located at one end of the telescopic slot 139 close to the silt discharge channel 131 (as shown in FIG. Fig. 9As shown), in order to prevent the staff from getting stuck in the silt discharge channel 131 due to impurities such as hair in the silt when pumping the silt. Finally, the first pressing plate and the second pressing plate in the present invention are both magnetic. When the staff needs to flush the sewer pipe with the help of high-pressure water flow, the two sets of electromagnets 137 can be used to drive the two sets of first pressing plates and the two sets of second pressing plates to move away from the electromagnets 137. At this time, the hydraulic oil in the two sets of liquid storage tanks will enter the two sets of sealing grooves 134 and the two sets of transmission grooves 138. Under the action of hydraulic pressure, the two sets of sealing plates 1341 will extend out of the sealing grooves 134 and close together. At the same time, the two sets of transmission blocks 1352 will rotate with the rotating shaft 1351 and the cleaning frame 135 to The cleaning frame 135 is unfolded at the side end of the dredging head 13, and the fixed pipe 11 is separated from the silt inlet pipe 132 by two sets of sealing plates 1341. When the fixed pipe 11 is separated from the silt inlet pipe 132, if the staff transmits high-pressure water flow to the working mechanism 1 through the second liquid pump 22, the two sets of movable blocks 1392 will be pushed into the telescopic groove 139 under the action of hydraulic pressure. At this time, the high-pressure water flow will flow out through the drainage channel 1391, thereby achieving the purpose of flushing and silting. Finally, when flushing the silt on the inner wall of the sewer pipe, the motor 123 will drive the dredging head 13 and the two sets of unfolded cleaning frames 135 to rotate continuously to perform friction cleaning on the inner wall of the sewer pipe.

[0025] like Fig. 9 As shown, each group of movable blocks 1392 is provided with a group of piezoelectric sheets at one end close to the second compression spring, and the piezoelectric sheets are electrically connected to the second liquid pump 22. When the high-pressure water flow is ejected from the telescopic groove 139 and the discharge channel 1391, the staff can determine whether the pressure of the high-pressure water flow sprayed onto the inner wall of the sewer pipe is too large by monitoring the changes in the electrical signals on the piezoelectric sheets, so as to facilitate the staff to adjust the pressure of the high-pressure water flow delivered by the second liquid pump 22 in real time as needed.

[0026] The working principle of the present invention is as follows: before working, the length of the support assembly 14 is adjusted to facilitate the subsequent movement of the working mechanism 1 in the sewer pipe. When the working mechanism 1 is placed in the sewer pipe, the motor 123 is turned on to rotate the dredging head 13. When there is a lot of sludge or dirt in the sewer pipe so that the sewer pipe is blocked, the staff can open the first valve and then use the first liquid pump 21 to extract the sludge and dirt in the sewer pipe. During the sludge extraction process, the dredging head 13 will continue to rotate to break up the sludge in the sewer pipe for subsequent extraction. When the sludge or dirt adheres to the inner wall of the sewer pipe, the staff can turn on the two groups of The electromagnet 137 causes the two sets of sealing plates 1341 to extend out of the sealing groove 134 and close together. At the same time, the two sets of transmission blocks 1352 will rotate with the rotating shaft 1351 and the cleaning frame 135. The fixed pipe 11 is separated from the silt inlet pipe 132 by the two sets of sealing plates 1341. At this time, the staff transmits high-pressure water flow to the working mechanism 1 through the second liquid pump 22. Under the action of hydraulic pressure, the two sets of movable blocks 1392 will be pushed into the telescopic groove 139, and the high-pressure water flow will flow out through the drainage channel 1391. Finally, when flushing the silt on the inner wall of the sewer pipe, the dredging head 13 will rotate continuously with the cleaning frame 135 to improve the dredging effect.

[0027] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. The embodiments should therefore be considered exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
