[0001] This utility model relates to the field of oil tank cleaning nozzle technology, specifically a replaceable pressure cap device for an oil tank mechanical cleaning machine nozzle. Background Technology

[0002] Oil tanks are large containers with relatively regular shapes used to store oil products. They can be divided into metal oil tanks and non-metal oil tanks according to the different construction materials. Most metal oil tanks are steel oil tanks, used in oil refineries, oil fields, oil depots and other industries. Usually, cleaning machines are used with spray nozzles to flush the inside of the oil tank.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] The existing oil tank mechanical cleaning nozzle and nozzle body rod are an integrated structure. If different diameter nozzles are required, the internal gear connection structure between the nozzle and the body rod makes it inconvenient to disassemble and replace the nozzle.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a replaceable cap device for the nozzle of an oil tank cleaning machine. Through the separate design of the cap body, the nozzle body, and the cleaning nozzle main rod, compared with the traditional integrated structure design of the cleaning nozzle main rod and the nozzle body, it is easier to disassemble and replace the cap body with nozzle bodies of different diameters, saving the time and effort of the staff.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A replaceable cap device for a tank cleaning machine nozzle includes a main cleaning nozzle rod. A connecting rod is fixedly installed at the bottom of the main cleaning nozzle rod. A support bearing is rotatably installed at the front end of the connecting rod via a sealing ring. A mounting seat extending to the outer side of the front end is rotatably installed inside the connecting rod. A cap body is provided at the front end of the support bearing and connected to the mounting seat via a sealing ring. The nozzle body is fixedly installed at the top and bottom of the cap body with a misalignment. An L-shaped limiting groove is formed at the top and bottom of the front end of the support bearing with a misalignment. An L-shaped limiting rod is fixedly installed at the top and bottom of the rear end of the cap body with a misalignment, and the L-shaped limiting rod extends into the interior of the L-shaped limiting groove.

[0009] Preferably, threaded holes are provided on both sides of the mounting base, and limit bolts extending into the threaded holes are threaded through both sides of the pressure cap body.

[0010] Preferably, a water delivery channel is provided at the rear end of the connecting rod, and an insertion tube extending into the mounting base is fixedly installed at the front end of the water delivery channel.

[0011] Preferably, the inside of the pressure cap body is provided with an annular channel, and the annular channel is connected to the mounting base and the nozzle body.

[0012] Preferably, a small gear disk is rotatably mounted inside the connecting rod, and a large gear disk that meshes with the small gear disk is fixedly mounted on the outer rear end of the mounting base.

[0013] Preferably, the pressure cap body is provided with protective caps on both sides located outside the limit bolts, and the protective caps are rotatably connected to the two sides of the pressure cap body by threads.

[0014] Compared with the prior art, this utility model provides a replaceable cap device for the nozzle of an oil tank cleaning machine, which has the following advantages: This utility model installs the cap body on one side of the support bearing. After the L-shaped limiting rod slides into the L-shaped limiting groove, the cap body is rotated counterclockwise so that one end of the L-shaped limiting rod slides into the L-shaped limiting groove for limiting and fixing, which is convenient for workers to install. If it is necessary to replace the nozzle body with a different diameter, the cap body can be easily disassembled and replaced by rotating clockwise. Compared with the traditional integrated structure design of the cleaning nozzle main rod and the nozzle body, it is easier to disassemble and replace the cap body with nozzle bodies of different diameters, saving workers' time and effort.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a replaceable pressure cap device for the nozzle of a mechanical cleaning machine for oil tanks.

[0024] Please see Figures 1-6 A replaceable cap device for a tank cleaning machine nozzle includes a cleaning nozzle main rod 1. A connecting rod 101 is fixedly installed at the bottom of the cleaning nozzle main rod 1. A support bearing 102 is rotatably installed at the front end of the connecting rod 101 via a sealing ring. A mounting seat 103 extending to the outer side of the front end is rotatably installed inside the connecting rod 101. A cap body 104 connected to the mounting seat 103 via a sealing ring is provided at the front end of the support bearing 102. A nozzle body 105 is fixedly installed at the top and bottom of the cap body 104 with a misalignment. An L-shaped limiting groove 106 is opened at the top and bottom of the front end of the support bearing 102 with a misalignment. An L-shaped limiting rod 107 is fixedly installed at the top and bottom of the rear end of the cap body 104 with a misalignment, and the L-shaped limiting rod 107 extends into the interior of the L-shaped limiting groove 106. Threaded holes 108 are opened on both sides of the mounting seat 103. Limiting bolts 109 extending into the threaded holes 108 are threaded through both sides of the cap body 104.

[0025] With the above structural arrangement, the opening of the L-shaped limiting groove 106 at the front end of the support bearing 102 of the replaceable cap device for the oil tank mechanical cleaning machine nozzle is larger than the width of the L-shaped limiting rod 107. By sliding the L-shaped limiting rod 107 into the L-shaped limiting groove 106 and then rotating the cap body 104 counterclockwise, one end of the L-shaped limiting rod 107 slides into the inner side of the L-shaped limiting groove 106 for limiting and fixing. Then, by extending the limiting bolt 109 through the cap body 104 into the threaded hole 108, the cap body 104 is fixedly connected to the front end of the mounting base 103, thereby fixing the cap body 104 in place. When the nozzle body 105 at the front end of the mounting base 103 needs to be replaced with a different diameter, the limiting bolt 109 is first removed from the inside of the threaded hole 108. Then, by rotating the mounting base 104 clockwise, the L-shaped limiting rod 107 slides out from the inside of the L-shaped limiting groove 106, making it easy to disassemble the mounting base 104 and replace the nozzle body 105 with a different diameter. Compared with the traditional integrated structure design of the cleaning nozzle main rod 1 and the nozzle body 105, it is easier to disassemble the mounting base 104 and replace the nozzle body 105 with a different diameter, saving the time and effort of the staff.

[0026] Furthermore, a water delivery channel 110 is provided at the rear end of the connecting rod 101, and an insertion tube 111 extending into the mounting base 103 is fixedly installed at the front end of the water delivery channel 110. An annular channel 112 is provided inside the cap body 104, and the annular channel 112 is connected to the mounting base 103 and the nozzle body 105. The insertion tube 111 extends into the mounting base 103, and then clean water is delivered to the annular channel 112 at the front end of the cap body 104 through the water delivery channel 110 and the insertion tube 111. The water is then sprayed out through the nozzle body 105 to clean the inside of the oil tank.

[0027] Furthermore, a small gear disk 2 is rotatably mounted inside the connecting rod 101, and a large gear disk 3 that meshes with the small gear disk 2 is fixedly mounted on the outer rear end of the mounting base 103. The oil tank mechanical cleaning machine driven by the cleaning machine's drive mechanism is a known existing device, and its working principle is common knowledge well-known to those skilled in the art and has been fully disclosed in the prior art. This will not be elaborated further here. The drive mechanism rotates the main rod 1 of the cleaning nozzle, causing the small gear disk 2 to drive the large gear disk 3 to rotate, thereby causing the mounting base 103 to drive the pressure cap body 104 to rotate. This allows the nozzle body 105 to clean the interior of the oil tank from all directions, improving the cleaning efficiency of the oil tank.

[0028] Furthermore, protective covers 4 are provided on both sides of the pressure cap body 104, located outside the limit bolt 109. The protective covers 4 are rotatably connected to both sides of the pressure cap body 104 via threads. Specifically, when the pressure cap body 104 is fixedly installed at the front end of the mounting base 103, the protective covers 4 are rotatably installed on both sides of the pressure cap body 104 via threads to protect the limit bolt 109, preventing the dirt inside the nozzle body 105 from easily adhering to the outside of the limit bolt 109 and making it difficult to disassemble when cleaning the inside of the oil tank.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
