Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically to a water jet dredging construction device for underground pipeline networks. Background Technology

[0002] Urban underground sewage pipe networks contain many sewage pipes, which often contain sewage, debris, and impurities such as cement mortar dumped by construction sites. These impurities easily settle and accumulate, leading to blockages after prolonged use. If these impurities are not treated in time, sewage overflows will occur, causing environmental pollution and, in severe cases, even significant economic losses, and inconveniencing residents' lives and production. Therefore, the dredging of urban underground water pipes is particularly important.

[0003] Pipeline water jetting is a widely used dredging method. It mainly uses a high-pressure water jetting vehicle (such as a large water tank, motorized hose reel, high-pressure water pump, water jet nozzle, etc.) to jet water into the pipeline for dredging. However, current underground pipeline water jetting dredging equipment cannot effectively remove blockages when encountering situations where pressurized water is difficult to clean, such as when objects are stuck in the mesh of the filter grate inside the pipeline.

[0004] Therefore, this application proposes a water jetting dredging construction device for underground pipe networks to solve the above-mentioned technical problems. Summary of the Invention

[0005] The main objective of this invention is to provide an underground pipe network water jetting dredging construction device that, during water jetting dredging, can also clear blockages in the mesh of filter grates within the pipe network.

[0006] The present invention solves the above-mentioned technical problems by adopting the following technical solutions:

[0007] A water jet dredging device for underground pipelines, mounted on a transport vehicle, is used to jet dredge a screen mesh built into one end of the pipeline. The device includes:

[0008] The cleaning mechanism is set at the bottom of the transport vehicle body via a second lifting rod on a second elevator. It includes a central control slide connected to the second lifting rod, a guide sleeve sliding on the central control slide, and multiple hollow push rods that are set on the guide sleeve and extend in the opposite direction along the guide sleeve for sliding through the mesh of the sieve grate.

[0009] The water spraying mechanism is used to supply water into the guide sleeve and drive the water flow inside the guide sleeve to spray into the pipe through one end of the hollow push rod.

[0010] Preferably, the water spraying mechanism includes a second water pump mounted on a second lifting rod, an inlet pipe with one end connected to the second water pump, a second filter screen mounted on the other end of the inlet pipe for filtering the water flowing into the inlet pipe, and an outlet pipe mounted on the second water pump for connecting the second water pump and the guide sleeve.

[0011] Preferably, the cleaning mechanism further includes an electric cylinder that moves synchronously up and down on the second lifting rod, a longitudinal connecting rod on the lifting drive end of the electric cylinder, a transverse connecting rod that passes through the central control slide and is connected to the guide sleeve, and a receiving connecting rod that is hinged at both ends to the longitudinal connecting rod and the transverse connecting rod respectively.

[0012] Preferably, the cleaning mechanism further includes multiple sets of wall scraping structures disposed at the water outlet end of the hollow push rod for rotating when the hollow push rod discharges water.

[0013] Preferably, the scraping structure includes a rubber plate that is movably flipped on the outside of the hollow push rod, a torsion spring disposed at one end of the rubber plate for connecting the hollow push rod, and a rubber protrusion disposed at the other end of the rubber plate for contacting the hollow push rod to spray water and moving.

[0014] When the hollow push rod is in the state of spraying water, the rubber protrusion contacts the hollow push rod and is rotated by the force of the spraying water. When the hollow push rod slides through the screen mesh, the rubber protrusion contacts and rubs against the inner wall of the screen mesh.

[0015] Preferably, it also includes a receiving hopper located at the bottom of the transport vehicle body via a first lifting rod on a first elevator, the receiving hopper being located at the other end of the pipeline.

[0016] Preferably, it also includes a flow guiding component disposed on the first elevator for guiding the water flow in the pipe from one end to the other end.

[0017] Preferably, the flow guiding component includes a first water pump mounted on the first elevator, a suction pipe connected at one end to the first water pump, and a first filter screen mounted at the other end of the suction pipe for filtering the water flowing into the suction pipe.

[0018] This invention provides a device for water jet dredging of underground pipe networks. Compared with existing technologies, the advantages of this invention are as follows:

[0019] 1. This invention provides a cleaning mechanism and a water spraying mechanism at one end of the pipeline where the filter grate is installed. When multiple hollow push rods are used for water jet cleaning, the longitudinal connecting rod is driven by an electric cylinder to move up and down repeatedly. Since the longitudinal connecting rod is hinged to the transverse connecting rod through the connecting rod, when the electric cylinder drives the longitudinal connecting rod to move up and down repeatedly, the guide sleeve slides back and forth in the central control slide, so that the hollow push rod can slide back and forth through the mesh of the filter grate in the pipeline while performing water jet cleaning. This effectively removes and cleans the blockages in the mesh of the pipeline network when performing water jet cleaning.

[0020] 2. This invention, by setting a flow guiding component and a collection funnel at the other end of the pipeline, utilizes the water flow generated by the first water pump to guide the cleaned blockage towards the collection funnel. Combined with the water jetting during the sludge removal process using the hollow push rod, the cleaned blockage is collected in the collection funnel. The first elevator then lifts the collection funnel to process the blockage. This allows for continuous and cyclical use of the device while facilitating centralized collection and cleaning of blockages inside the pipeline. It protects the environment and allows for the recycling of the blockage as a resource, making it a green and environmentally friendly solution.

[0021] 3. This invention incorporates multiple scraping structures at the jetting end of the hollow push rod for water jet dredging. When water flows through the hollow push rod, it contacts the rubber protrusions near the push rod, causing the water to expand outwards due to the pressure of the jetting. Simultaneously, as the hollow push rod inserts into the mesh of the filter grate inside the pipe, the outer side of the rubber protrusions contacts the inner wall of the filter grate mesh, resulting in sliding friction. This process removes and separates sticky substances that are difficult to clean from the inner wall of the filter grate mesh, improving the cleaning efficiency of the pipe during water jet dredging.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] For details in the embodiments, please refer to Figures 1 to 5 .

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, this invention provides an underground pipeline water jetting dredging construction device, which is installed at the bottom of a transport vehicle 1 via a first elevator 2 and a second elevator 5, for water jetting dredging of a screen 81 built into one end of the pipeline 8, including:

[0033] The cleaning mechanism 6 is set at the bottom of the transport vehicle body 1 via the second lifting rod 51 on the second lifting machine 5. It includes a central control slide 63 connected to the second lifting rod 51, a guide sleeve 62 sliding on the central control slide 63, and a plurality of hollow push rods 61 that are set on the guide sleeve 62 and extend in the opposite direction along the guide sleeve 62 for sliding through the mesh of the screen 81.

[0034] The water spraying mechanism 7 is used to supply water into the guide sleeve 62 and drive the water flow in the guide sleeve 62 to be sprayed into the pipe 8 through one end of the hollow push rod 61.

[0035] The cleaning mechanism 6 is located at one end of the pipe 8 where the filter grate is installed. When multiple hollow push rods 61 are used for water jet cleaning, the hollow push rods 61 can also slide through the mesh of the screen grate 81 and slide back and forth, so as to effectively remove and clean the blockage of the mesh of the pipe network when performing water jet cleaning operation on the pipe 8.

[0036] When in use, the device is operated by moving the transport vehicle 1 to allow the cleaning mechanism 6 and the water spraying mechanism 7 to enter the water area where the underground pipe network is located.

[0037] Furthermore, it should be noted that the aforementioned transport vehicle body 1 is an existing means of transportation; the first elevator 2 and the second elevator 5 are of the same model and have similar structures, and are equipped with control panels for operation. The first lifting rod 21 or the second lifting rod 51 on the first elevator 2 and the second elevator 5 can be stopped at a certain position by touching the control panel; the hollow push rod 61 mentioned above is set as a tubular structure with a circular hole in its cross section, and the water flow of the water spraying mechanism 7 is sprayed out through the circular hole in the tubular structure of the hollow push rod 61.

[0038] like Figure 1 and Figure 2 As shown, the water spraying mechanism 7 includes a second water pump 71 mounted on the second lifting rod 51, an inlet pipe 72 connected to the second water pump 71 at one end, a second filter screen 74 mounted on the other end of the inlet pipe 72 for filtering the water flowing into the inlet pipe 72, and an outlet pipe 73 mounted on the second water pump 71 for connecting the second water pump 71 and the guide sleeve 62. The second water pump 71 can pump water from the water area into the guide sleeve 62 through the inlet pipe 72 and the outlet pipe 73. At this time, the second filter screen 74 can filter substances in the water that affect the operation of the second water pump 71, thereby reducing the failure rate of the second water pump 71.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the cleaning mechanism 6 also includes an electric cylinder 67 that moves synchronously up and down on the second lifting rod 51, a longitudinal connecting rod 66 that is set on the lifting drive end of the electric cylinder 67, a transverse connecting rod 64 that passes through the central control slide 63 and is connected to the guide sleeve 62, and a receiving connecting rod 65 that is hinged at both ends to the longitudinal connecting rod 66 and the transverse connecting rod 64 respectively.

[0040] It should be noted that the electric cylinder 67 is a single-stroke type, and its operation is controlled by powering it on and off. At this time, the guide sleeve 62 has a stepped guide groove, and the hollow slide and the hollow push rod 61 form a stepped structure. The movable distance of the hollow slide in the stepped guide groove is greater than the stroke of the electric cylinder 67. The longitudinal connecting rod 66 is fixedly connected to the reciprocating motion part of the electric cylinder 67.

[0041] In practice, the electric cylinder 67 drives the longitudinal connecting rod 66 to move linearly up and down in a reciprocating motion. The longitudinal connecting rod 66 transmits power to the transverse connecting rod 64 by receiving the swing action of the connecting rod 65. The transverse connecting rod 64 will move linearly up and down in a reciprocating motion due to the restriction of the guide sleeve 62. At this time, the transverse connecting rod 64 drives the hollow slide and the hollow push rod 61 to move together, thereby using the hollow push rod 61 to clear the blockages such as silt blocks on the pipeline.

[0042] It should be noted that the electric cylinder 67 can also be replaced by other structures with the same reciprocating motion function.

[0043] In summary, when multiple hollow push rods 61 are used for water jet cleaning, the longitudinal connecting rod 66 is driven to reciprocate up and down by the electric cylinder 67. Since the longitudinal connecting rod 66 is movably hinged to the transverse connecting rod 64 through the receiving connecting rod 65, the guide sleeve 62 slides back and forth in the central control slide 63 when the electric cylinder 67 drives the longitudinal connecting rod 66 to reciprocate up and down. This allows the hollow push rods 61 to reciprocate and slide through the mesh of the filter grate in the pipe 8 while performing water jet cleaning, thus effectively clearing and cleaning the blockages in the mesh of the pipe network during the water jet cleaning operation of the pipe 8.

[0044] In addition, such as Figure 3 , Figure 4 and Figure 5 As shown, the cleaning mechanism 6 also includes multiple sets of scraping structures 68 disposed at the water outlet end of the hollow push rod 61 for rotating when the hollow push rod 61 discharges water.

[0045] The wall scraping structure 68 includes a rubber plate 682 that is movably flipped on the outside of the hollow push rod 61, a torsion spring 681 set at one end of the rubber plate 682 for connecting the hollow push rod 61, and a rubber protrusion 683 set at the other end of the rubber plate 682 for contacting the hollow push rod 61 to spray water and move.

[0046] Specifically, the rubber protrusion 683 has a force-bearing arc surface 6831 on the side near the hollow push rod 61, and a friction arc surface 6832 on the side of the rubber protrusion 683 near the hollow push rod 61. The friction arc surface 6832 can be provided with friction textures to improve friction. That is to say, when the hollow push rod 61 is spraying water, the water flow contacts the force-bearing arc surface 6831, and the rubber protrusion 683 expands and flips outward with the pressure of the water flow. At this time, when the hollow push rod 61 slides through the mesh of the screen 81, the friction arc surface 6832 of the rubber protrusion 683 contacts and rubs against the inner wall of the mesh of the screen 81, thereby peeling off and separating the sticky objects that are difficult to clean from the mesh of the filter grate from the inner wall of the mesh for cleaning, thereby improving the cleaning efficiency of the screen blockage during water jet dredging.

[0047] like Figure 1 and Figure 2 As shown, the device also includes

[0048] The receiving hopper 3 is set at the bottom of the transport vehicle body 1 via the first lifting rod 21 on the first elevator 2, and the receiving hopper 3 is also set at the other end of the pipe 8;

[0049] The flow guiding component 4 is installed on the first elevator 2 to guide the water flow in the pipe 8 from one end to the other end.

[0050] It should be noted that the receiving funnel 3 can be set with a plate-shaped bottom with a depression and a mesh on the side, which is a traditional receiving funnel 3 structure. This structure has a good foreign matter collection effect. Other structures can also be used to replace the receiving funnel 3.

[0051] In specific implementation, a flow guiding component 4 and a collection funnel are set at the other end of the pipe 8. The water flow generated by the first water pump 41 can guide the cleaned blockage to move towards the collection funnel. When the hollow push rod 61 sprays water to clean the sludge, the water flow sprayed into the pipe 8 can allow the cleaned blockage to enter the collection funnel for collection. At this time, the first elevator 2 can be used to lift the collection funnel to process the blockage. This makes it convenient for the device to be used continuously and also makes it convenient to collect and clean the blockage inside the pipe 8. This not only protects the environment, but also makes it convenient to recycle the blockage as a resource, which is green and environmentally friendly.

[0052] The flow guiding component 4 includes a first water pump 41 installed on the first elevator 2, a suction pipe 42 connected to the first water pump 41 at one end, and a first filter screen 43 installed at the other end of the suction pipe 42 for filtering the water flow entering the suction pipe 42. At this time, the first filter screen 43 can filter substances in the water that affect the operation of the first water pump 41, thereby reducing the failure rate of the first water pump 41.

[0053] When in use, the second water pump 71 is powered on, and water enters the inlet pipe 72 through the second filter screen 74, generating a water flow. This flow has a guiding effect on the cleaned silt and other blockages, causing the blockages to move towards the collection funnel 3 for better collection.

[0054] In summary, when the device is in actual use, the transport vehicle 1 moves to the designated work location, the first elevator 2 operates through the transmission of the first lifting rod 21, causing the receiving hopper 3 to enter the water area where the underground pipe network is located, and the second elevator 5 operates through the transmission of the second lifting rod 51, causing the cleaning mechanism 6 and the water spraying mechanism 7 to enter the water area where the underground pipe network is located, opposite to the receiving hopper 3, with the pipe network located between the two. The water spraying mechanism 7 sprays pressurized water to help the cleaning mechanism 6 clean the pipe network.
