Description

Technical Field

[0001] This invention relates to the field of tank bottom cleaning, and more particularly to a tank bottom cleaning device. Background Technology

[0002] When cleaning the bottom of drilling mud tanks, corresponding cleaning nozzles are usually set up according to the different locations of obstacles on the bottom of the tank. The spraying end of the cleaning nozzle sprays vertically downwards to the bottom of the tank. At the same time, the up and down extension and retraction of the cleaning nozzle is achieved by pneumatic or electric drive. This has a large spraying range, which cannot effectively clean the bottom of the tank and has low cleaning efficiency. In addition, the cleaning nozzles need to be installed inside the tank body, and the opening diameter of the tank body needs to be increased to facilitate the insertion of the cleaning nozzles. This makes the tank body modification work extensive and costly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a tank bottom cleaning device with a large spray range, good spray effect and high efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0005] A tank bottom cleaning device includes a cleaning nozzle and a nozzle guide assembly. The nozzle guide assembly includes a guide tube, a telescopic hose, and an extension tube. The extension end of the guide tube is positioned facing the bottom of the tank. The telescopic hose is movably inserted into the guide tube, and its head end is drivenly connected to the cleaning nozzle. The extension tube is sleeved between the guide tube and the telescopic hose, and extends out of the guide tube under the drive of the cleaning nozzle.

[0006] As a further improvement to the above technical solution:

[0007] Both the guide tube and the extension tube are provided with nozzle guide grooves arranged along the tube body axis. The extension end of the guide tube is provided with a through part communicating with the nozzle guide groove. The cleaning nozzle is movably disposed in the nozzle guide groove and passes through the through part when the extension tube is driven.

[0008] One end of the extension tube is a sealing end, and the telescopic hose abuts against the sealing end when the extension tube is driven.

[0009] The outer surface of the extension tube is provided with an extension limiting part, which engages with the insertion end of the guide tube when the extension tube extends to a certain length.

[0010] A retraction limiting component is provided between the extension tube and the telescopic hose to drive the extension tube to retract when the telescopic hose retracts. The retraction limiting component includes two mating protrusions, which are provided on the extension tube and the telescopic hose.

[0011] The cleaning nozzle includes a mounting connector and at least two cleaning nozzles, the cleaning nozzles being arranged along the outer periphery of the mounting connector and being driven connected to the telescopic hose through the mounting connector.

[0012] The end of the telescopic hose furthest from the cleaning nozzle is connected to a nozzle liquid supply system; the mounting connector is provided with a liquid supply through hole, which connects the telescopic hose to the cleaning nozzle.

[0013] The guide tube includes a vertical section and an inclined section that are connected to each other, wherein the vertical section is fixedly installed outside the tank body; the connecting end of the inclined section is higher than the other end of the inclined section.

[0014] It also includes a reel assembly, which includes a reel and a reel mounting bracket, the reel mounting bracket being mounted on the guide tube, and the telescopic hose being wound around the reel.

[0015] The roller mounting frame is equipped with a lifting frame that facilitates the installation and removal of the tank bottom cleaning device.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] The nozzle guide assembly of this invention features a compact and ingenious design. It drives the cleaning nozzle to move via a telescopic hose and further expands the nozzle's range of motion via an extension tube. This allows the cleaning nozzle to clean a large area of ​​the tank bottom, achieving impact-breaking of deposits at different locations on the tank bottom. This effectively avoids the problems of poor performance and low efficiency associated with using multiple cleaning nozzles. This invention significantly improves cleaning effect and efficiency. Furthermore, the cleaning device can be placed into the tank via the guide tube, eliminating the need to enlarge the tank opening and minimizing the workload and cost of modifying the tank.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of the present invention.

[0029] like Figures 1 to 7 This embodiment of the tank bottom cleaning device of the present invention is shown. This device can be used for cleaning the bottom of drilling mud tanks, and also for cleaning the bottoms of other tanks. In this embodiment, the tank bottom cleaning device includes a cleaning nozzle 1 and a nozzle guide assembly 2. The nozzle guide assembly 2 includes a guide tube 21, a telescopic hose 22, and an extension tube 23. The insertion end of the guide tube 21 faces the tank bottom 31. The telescopic hose 22 is movably inserted into the guide tube 21, and its head end is drivenly connected to the cleaning nozzle 1. The extension tube 23 is sleeved between the guide tube 21 and the telescopic hose 22, and extends out of the guide tube 21 under the drive of the cleaning nozzle 1.

[0030] The nozzle guide assembly 2 of this invention features a compact and ingenious design. It drives the cleaning nozzle 1 to move via a telescopic hose 22 and further expands the movement range of the cleaning nozzle 1 via an extension tube 23. This allows the cleaning nozzle 1 to perform large-area cleaning of the tank bottom 31, achieving impact-breaking of deposits at different locations on the tank bottom 31. This effectively avoids the problems of poor performance and low efficiency associated with using multiple cleaning nozzles 1. This invention significantly improves cleaning effect and efficiency. Furthermore, this invention allows the cleaning device to be placed inside the tank via the guide tube 21, eliminating the need to enlarge the opening of the tank body 3, resulting in minimal workload and low cost in modifying the tank body 3.

[0031] In this embodiment, both the guide tube 21 and the extension tube 23 are provided with nozzle guide grooves 4, which are arranged along the axial direction of the tube body. The extension end of the guide tube 21 is provided with a through part, which communicates with the nozzle guide groove 4. The cleaning nozzle 1 is movably disposed in the nozzle guide groove 4 by the drive of the telescopic hose 22, and the cleaning nozzle 1 passes through the through part when the extension tube 23 is driven. The through part avoids the guide tube 21 from interfering with the movement of the cleaning nozzle 1.

[0032] like Figures 2 to 6 As described above, one end of the extension tube 23 is a sealing end 231. When the extension tube 23 is driven, the telescopic hose 22 abuts against the sealing end 231 to effectively drive the extension tube 23 to move out of the guide tube 21. In other embodiments, any structure in which one end of the telescopic hose 22 can cooperate with the extension tube 23 and drive the extension tube 23 to move should be within the protection scope of this invention. For example, a limiting boss that abuts against the telescopic hose 22 can also be provided at one end of the extension tube 23.

[0033] When the cleaning nozzle 1 moves, the telescopic hose 22 drives the cleaning nozzle 1 to move within the nozzle guide groove 4. When the cleaning nozzle 1 moves to the front end of the nozzle guide groove 4 of the guide tube 21, it engages with the sealing end 231 of the extension tube 23. At this time, the cleaning nozzle 1 continues to pass through the through part of the guide tube 21 under the drive of the telescopic hose 22, driving the extension tube 23 to extend out of the guide tube 21, thereby adjusting the spray range of the cleaning nozzle 1.

[0034] like Figure 5 As shown, the outer surface of the extension tube 23 is provided with an extension limiting part 232. When the extension tube 23 extends to a certain length, the extension limiting part 232 cooperates with the extension end of the guide tube 21 to limit the extension displacement of the extension tube 23. The extension length of the cleaning nozzle 1 after it is separated from the guide tube 21 depends on the extension displacement of the extension tube 23.

[0035] In this embodiment, a retraction limiting component 5 is provided between the extension tube 23 and the telescopic hose 22. The retraction limiting component 5 includes two mating protrusions 51, which are respectively disposed on the extension tube 23 and the telescopic hose 22. Figure 6 As shown, the two mating protrusions 51 engage when the telescopic hose 22 retracts to a certain distance. At this time, the telescopic hose 22 drives the extension tube 23 to retract into the guide tube 21. The extension limiting part 232 and the retraction limiting part 5 enable the effective extension and retraction of the extension tube 23, ensuring the reliable operation of the cleaning nozzle 1 for wide-range spraying.

[0036] Furthermore, such as Figure 1 and 7As shown, the cleaning nozzle 1 includes a mounting connector 11 and at least two cleaning nozzles 12. The cleaning nozzles 12 are arranged along the outer periphery of the mounting connector 11 to increase the spray range of the cleaning nozzle 1; at the same time, the cleaning nozzles 12 are driven to the telescopic hose 22 through the mounting connector 11 to enable the cleaning nozzles 12 to move effectively.

[0037] In this embodiment, the end of the telescopic hose 22 away from the cleaning nozzle 1 is connected to the nozzle liquid supply system; the mounting connector 11 is provided with a liquid supply through hole, which connects the telescopic hose 22 and the cleaning nozzle 12 to provide high-pressure clean water to the cleaning nozzle 1, thereby achieving impact crushing of the sludge at the bottom of the tank 31.

[0038] like Figure 1 As shown, the guide tube 21 includes a vertical section 211 and an inclined section 212 that are interconnected. The vertical section 211 is fixedly installed outside the tank body 3; the connecting end of the inclined section 212 is higher than the other end of the inclined section 212, causing the cleaning nozzle 1 to extend and retract towards the tank bottom 31 to spray. In this embodiment, the vertical section 211 is fixedly installed outside the tank body 3 via a flange, and the inclined section 212 is connected to the vertical section 211 via a flange.

[0039] Furthermore, the tank bottom cleaning device also includes a reel assembly 6, which includes a reel 61 and a reel mounting bracket 62. The reel 61 is mounted on the reel mounting bracket 62, which is mounted on the guide tube 21. A telescopic hose 22 is wound around the reel 61. When the reel 61 rotates clockwise, it guides the telescopic hose 22 into the guide tube 21; when the reel 61 rotates counterclockwise, it pulls the telescopic hose 22 out. This allows for convenient extension and retraction of the telescopic hose 22 and ensures rapid adjustment of the spray range of the cleaning nozzle 1. In this embodiment, the reel 61 can be rotated manually or electrically.

[0040] Furthermore, the roll mounting frame 62 is equipped with a lifting frame 7 to facilitate the hoisting of the tank bottom cleaning device and to facilitate the installation and disassembly of the tank bottom cleaning device.

[0041] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
