Description

Technical Field

[0001] This application relates to the technical field of plant root treatment equipment for municipal pipelines, and in particular to a plant root cleaning device for the interior of municipal pipelines. Background Technology

[0002] Currently, municipal sewage pipe networks are a massive and systematic project. Municipal sewage pipes are widely distributed throughout the city. As municipal sewage pipes are the main body that directly connects the sewage pipe network to the outside world, during the long-term process of sewage discharge and drainage, large trees such as landscape trees and roadside trees, due to their vigorous vitality, take root and eventually encroach on the inside of the sewage pipes. Over time, the encroaching tree roots grow and expand inside the pipes, seriously affecting the sewage discharge and increasing the damage to the pipe structure. Once municipal pipeline maintenance personnel discover tree roots encroaching on the pipes, they need to clean them up as soon as possible, as the difficulty of cleaning increases sharply after the tree roots grow and expand.

[0003] In related technologies, since landscape trees and roadside trees on the ground need to be preserved, municipal pipeline maintenance personnel cannot use pesticides such as tree killers that directly kill trees to clean the root system inside the pipeline. The existing method is to use sampling machinery to cut the root system. However, the root system inside the pipeline is relatively soft and dense, so mechanical cutting is not effective. Moreover, mechanical cutting requires maintenance personnel to enter the depths of the pipe at close range, which is a harsh environment and poses occupational safety risks. Utility Model Content

[0004] The purpose of this application is to provide a device for cleaning plant roots inside municipal pipelines, in order to solve the problems of existing methods that use sampling machinery to cut off the roots. However, the roots inside the pipeline are soft and dense, and the mechanical cutting is not effective. Furthermore, mechanical cutting requires maintenance personnel to enter the deep part of the pipeline at close range, which is a harsh environment and poses occupational safety risks.

[0005] The technical solution for the device for cleaning plant roots inside municipal pipelines provided in this application is as follows:

[0006] A device for cleaning plant roots inside municipal pipelines includes a main rod, a high-speed rotating impeller at the front end of the main rod, a liquid supply pipe connected to the liquid inlet end of the high-speed rotating impeller, a portable steam generator connected to the end of the liquid supply pipe away from the high-speed rotating impeller, and a concentrated brine supply assembly connected to the liquid inlet end of the portable steam generator.

[0007] Furthermore, a connecting hole is provided inside the main body rod, and the connecting hole cooperates with the liquid supply pipe.

[0008] Furthermore, an extension sleeve is provided at the end of the main rod away from the high-speed rotating impeller via a fixing component. The extension sleeve has an extension hole inside that communicates with the connecting hole, and the extension hole cooperates with the liquid supply pipe.

[0009] Furthermore, the fixing component includes a fixing internal thread disposed within the wall of the extension hole, and a fixing external thread disposed on the outer side of one end of the main body rod, which is threadedly connected to the fixing internal thread.

[0010] Furthermore, an operating handle is provided on the outer side of one end of the extension sleeve.

[0011] Furthermore, the concentrated brine supply assembly includes a concentrated brine tank, a water pump is provided on the outside of the concentrated brine tank, a suction pipe is connected between the suction end of the water pump and the concentrated brine tank, and a drain pipe is connected between the discharge end of the water pump and the liquid inlet end of the portable steam generator.

[0012] Furthermore, a folding wheel shaft is provided on the outer side of the main body rod near the high-speed rotating impeller, and movable wheels are provided at both ends of the folding wheel shaft.

[0013] Furthermore, several lighting lamps are also provided on the outer side of the main body rod.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] By employing a structure that integrates a main rod, a high-speed rotating impeller, a liquid supply pipe, a portable steam generator, and a concentrated brine supply assembly, concentrated brine can be discharged into the portable steam generator, which then provides high-temperature steam from the concentrated brine. This high-temperature steam is then delivered through the liquid supply pipe to the high-speed rotating impeller, which breaks the high-temperature concentrated brine into droplets with a diameter of 90μm. These droplets are then sprayed as a water mist onto the root system within the pipe. This method effectively cleans the roots encroaching on the pipe using high-temperature concentrated brine. In this environment, the high salt concentration causes the tree roots to dehydrate rapidly, effectively killing only the roots within the pipe while having minimal impact on the tree roots on the ground.

[0019] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0020] This application discloses a device for cleaning plant roots inside municipal pipelines, referring to... Figure 1 In this embodiment, the plant root cleaning device includes a main rod 1, a high-speed rotating impeller 2, a liquid supply pipe 3, a portable steam generator 4, and a concentrated brine supply assembly. The high-speed rotating impeller 2 is installed at the front end of the main rod 1. This impeller 2 is a nozzle capable of breaking high-temperature concentrated brine into droplets with a diameter of 90μm, causing the sprayed high-temperature concentrated brine to form a water mist in front of it, thereby greatly increasing the contact area between the high-temperature concentrated brine and the roots inside the pipe.

[0021] To elaborate further, the installation method between the high-speed rotating impeller 2 and the main body rod 1 can also be designed as a detachable installation method. This allows the high-speed rotating impeller 2 to be removed from the main body rod 1 for easy maintenance, replacement, cleaning, or storage.

[0022] Meanwhile, in this embodiment, a connecting hole is provided inside the main body rod 1. One end of the liquid supply pipe 3 cooperates with the connecting hole, so that the liquid supply pipe 3 passes through the connecting hole through the main body rod 1 and is fixedly connected to the liquid inlet end of the high-speed rotating impeller 2. Thus, the high-temperature concentrated brine is discharged into the high-speed rotating impeller 2 through the liquid supply pipe 3. In addition, the connecting hole effectively protects one end of the liquid supply pipe 3, preventing the liquid supply pipe 3 from being exposed outside the main body rod 1 and suffering root damage.

[0023] To elaborate, the liquid supply pipe 3 is made of soft and high-temperature resistant materials. This not only allows the liquid supply pipe 3 to be bent so that it can be extended into the interior of the pipeline from the ground, but also makes the liquid supply pipe 3 resistant to high temperatures, thereby preventing operators from being burned by high temperatures when touching the liquid supply pipe 3.

[0024] Additionally, refer to Figure 1 In this embodiment, the portable steam generator 4 is placed on the ground. The liquid outlet of the portable steam generator 4 is fixedly connected to the end of the liquid supply pipe 3 away from the high-speed rotating impeller 2. The portable steam generator 4 can heat the concentrated brine to form high-temperature steam of the concentrated brine.

[0025] The concentrated brine supply component is placed on the ground and located on one side of the portable steam generator 4. The concentrated brine supply component is fixedly connected to the liquid inlet of the portable steam generator 4 so as to supply concentrated brine into the portable steam generator 4.

[0026] Specifically, refer to Figure 1In this embodiment, the concentrated brine supply assembly includes a concentrated brine tank 6, a water supply pump 61, a suction pipe 62, and a drain pipe 63. The concentrated brine tank 6 is placed on the ground and contains concentrated brine. The water supply pump 61 is installed on the outside of the concentrated brine tank 6. One end of the suction pipe 62 is connected to the suction end of the water supply pump 61, and the other end is connected to the inside of the concentrated brine tank 6. One end of the drain pipe 63 is connected to the discharge end of the water supply pump 61, and the other end is connected to the inlet end of the portable steam generator 4.

[0027] When the water supply pump 61 is started, the concentrated brine in the concentrated brine tank 6 is drawn into the drain pipe 63 through the suction pipe 62, and then discharged into the portable steam generator 4 along the drain pipe 63, so that the portable steam generator 4 can heat the concentrated brine to form high-temperature steam of concentrated brine.

[0028] In addition, refer to Figure 1 In this embodiment, an extension sleeve 5 is installed at the end of the main body rod 1 away from the high-speed rotating impeller 2 by a fixing component. The extension sleeve 5 has an extension hole inside. When the extension sleeve 5 is installed at one end of the main body rod 1 by the fixing component, the extension hole is connected to the connecting hole.

[0029] Simultaneously, the extension hole cooperates with the liquid supply pipe 3, allowing the liquid supply pipe 3 to pass through the extension sleeve 5 along the extension hole and extend into the connecting hole of the main body rod 1. This effectively protects the liquid supply pipe 3, ensuring that the operator is not burned. Furthermore, by having one end of the main body rod 1 fitted with the extension sleeve 5, the operator can remotely control the main body rod 1 and the high-speed rotating impeller 2 from the extension sleeve 5, thus ensuring that the operator does not need to enter deep into the pipeline, thereby avoiding the possibility of high-temperature burns.

[0030] Specifically, in this embodiment, the fixing component includes a fixing internal thread and a fixing external thread. The fixing internal thread is disposed inside the wall of the extension hole; the fixing external thread is disposed on the outer side of one end of the main body rod 1, and the fixing external thread and the fixing internal thread are threadedly connected to each other, so that one end of the extension sleeve 5 is screwed into one end of the main body rod 1, thereby fixing the extension sleeve 5 and the main body rod 1.

[0031] Preferably, in this embodiment, an operating handle 51 is installed on the outer side of the end of the extension sleeve 5 away from the main body rod 1. The operating handle 51 makes it easier for the operator to operate the entire cleaning device.

[0032] Secondly, refer to Figure 1In this embodiment, a folding wheel shaft is installed on the outer side of the main body rod 1 near the high-speed rotating impeller 2, and movable wheels 7 are installed on both ends of the folding wheel shaft. By setting the structure in which the folding wheel shaft and the movable wheels 7 cooperate with each other, the folding wheel shaft can be used to facilitate the entire cleaning device to enter the pipe. The movable wheels 7 are opened only after reaching the target pipe, and finally the movable wheels 7 are used to facilitate the movement of the main body rod 1 and the high-speed rotating impeller 2 in the pipe.

[0033] In addition, in this embodiment, several lighting lamps 8 are installed on the outside of the main rod 1. By setting these lighting lamps 8, the operator can easily observe the root encroachment position in the pipeline, thereby ensuring that the high-temperature concentrated brine is accurately sprayed to the root system.

[0034] The implementation principle of the municipal pipeline internal plant root cleaning device in this application embodiment is as follows: When it is necessary to clean the roots encroaching on the pipeline, the operator holds the extension sleeve 5 to take the main body rod 1 and the high-speed rotating impeller 2 into the pipeline, and then starts the water supply pump 61 to draw the concentrated brine in the concentrated brine tank 6 into the drain pipe 63 through the water suction pipe 62. Then, it is discharged into the portable steam generator 4 along the drain pipe 63, so that the portable steam generator 4 can heat the concentrated brine to form high-temperature steam. Then, the high-temperature steam reaches the high-speed rotating impeller 2 along the liquid supply pipe 3 and is basically cooled into high-temperature concentrated brine. The high-speed rotating impeller 2 forms water mist to spray and clean the roots encroaching on the pipeline, thereby completing the cleaning process of the roots encroaching on the pipeline.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
