Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a device for cleaning the inner wall of a testing box. Background Technology

[0002] In environmental monitoring and chemical analysis, testing chambers are widely used to contain liquids to be tested, such as wastewater or chemical reagents. To facilitate real-time observation by operators of the liquid's internal state, precipitation, or reaction processes, these testing chambers are typically made of transparent materials.

[0003] However, when the testing chamber is used for extended periods to hold liquids containing high levels of impurities, such as sewage, sludge, suspended solids, or microorganisms in the liquid can easily adhere to the inner wall of the chamber, gradually forming a layer of dirt or growing moss. This buildup severely affects the transparency of the chamber, interfering with the operator's observation and even leading to inaccurate test data. Therefore, regular cleaning of the inner wall is necessary.

[0004] Existing cleaning methods have significant drawbacks. Manual disassembly and cleaning is not only cumbersome, time-consuming, and labor-intensive, but frequent disassembly and reassembly can also damage the original seal of the testing chamber. Mechanical cleaning, such as drilling holes in the chamber and installing a drive shaft that passes through the chamber wall to drive the internal cleaning brush, achieves automation, but a dynamic seal must be installed between the drive shaft and the chamber. This dynamic seal is prone to wear after prolonged reciprocating motion or rotation, leading to seal failure and the risk of liquid leakage. This is unacceptable for testing chambers that require strict sealing. Therefore, an internal wall cleaning device for testing chambers is proposed to solve these problems. Utility Model Content

[0005] In view of the problems in the existing technology, such as the difficulty in effectively cleaning the inner wall dirt of the test box while maintaining the airtightness of the box, and the complexity and inefficiency of connecting and installing the drive mechanism and cleaning components, this utility model aims to provide an inner wall cleaning device for a test box with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an inner wall cleaning device for a testing box, comprising: a box body, an inner frame, a moving component, a driving mechanism, a moving block, and an installation mechanism.

[0007] The inner frame is vertically movable inside the box, and a second magnet is fixed on the inner frame; the movable component is vertically movable outside the box, and the movable component includes a movable frame and a first magnet fixed on the movable frame.

[0008] Furthermore, the magnetic attraction between the first and second magnetic magnets on the wall of the enclosure creates a non-contact magnetic coupling structure. This ensures that the driving force is transmitted without compromising the enclosure's seal, while simultaneously driving the inner frame to move vertically, achieving both efficient cleaning and leak prevention.

[0009] The drive mechanism includes a motor block for mounting, a drive source fixed to the motor block, a threaded rod driven to rotate by the drive source, and a sliding block threaded onto the threaded rod; a movable block is fixedly connected to the sliding block.

[0010] Furthermore, the power source is efficiently converted into the linear motion of the sliding block through the rotational motion of the threaded rod, providing a stable, smooth, and easily controllable power source for subsequent cleaning actions, with a simple and reliable structure.

[0011] The mounting mechanism is used to detachably connect the movable block and the movable component to the movable frame. The mounting mechanism has a first fixed block disposed on the movable block; a second fixed block disposed on the movable frame, the second fixed block having a limit groove; a damping rod installed in the first fixed block; a limit block pushed by the elastic force of the damping rod, the limit block being pluggably fitted in the limit groove of the second fixed block; and a second threaded rod, the second threaded rod passing through the first fixed block and threadedly connected to the second fixed block.

[0012] Furthermore, the installation mechanism achieves rapid initial positioning of fixed block one and fixed block two through the elastic cooperation of the damping rod and the limiting block. The operator can insert them without precise alignment. Then, the threaded rod two is used for firm locking. This design of positioning first and then locking greatly simplifies the installation and disassembly steps and improves the convenience of operation.

[0013] Preferably, the inner wall cleaning device of the testing box further includes a bottom shell and a top plate, with the box body vertically arranged on top of the bottom shell and the top plate covering the top of the box body.

[0014] Furthermore, the bottom shell, the housing, and the top plate together form a sealed cavity for containing the liquid to be tested, providing a basic installation platform and working space for the entire device, resulting in a stable structure.

[0015] Preferably, an inner wall cleaning device for a testing chamber further includes a feed pipe that passes through the top plate and extends downward into the interior of the chamber.

[0016] Furthermore, the feed pipe facilitates the injection of wastewater or the liquid to be tested, while its design, which penetrates the top plate, ensures the convenience of the feeding process and does not interfere with the operation of the cleaning mechanism located on the side wall of the chamber.

[0017] Preferably, the threaded rod of the drive mechanism is vertically arranged, and the sliding block slides up and down along the axial direction of the threaded rod.

[0018] Furthermore, the vertical setting of the threaded rod ensures that the sliding block can generate smooth vertical linear movement, which is crucial for effectively cleaning the inner wall of the moving components and inner frame, and avoids jamming caused by tilting of the movement.

[0019] Preferably, the drive source is detachably mounted on the motor block via a plug-in connection.

[0020] Furthermore, this plug-in, detachable installation method greatly facilitates the inspection, maintenance, or replacement of the drive source when a fault occurs, reducing the difficulty and cost of long-term equipment maintenance.

[0021] Preferably, the movable frame has a U-shaped structure and surrounds the three opposite sides of the outer side of the box.

[0022] Furthermore, the U-shaped structure allows the moving frame to simultaneously cover and drive the inner frames on multiple sides of the housing, achieving simultaneous cleaning over a wider area and improving cleaning efficiency per cycle.

[0023] Preferably, the surface of the inner frame facing the inner wall of the box is detachably equipped with a cleaning element.

[0024] Furthermore, the detachable design of the cleaning components (such as brushes or sponges) allows operators to flexibly change different types of cleaning components depending on the type of dirt (such as hard scale or soft moss), and the cleaning components can be easily replaced after wear, extending the service life of the device.

[0025] Preferably, the enclosure is made of a transparent material.

[0026] Furthermore, the use of transparent materials is fundamental to realizing the "testing box" function of this invention. It allows operators to observe the liquid state inside the box from the outside in real time, and the purpose of the inner wall cleaning device is precisely to maintain this transparent visibility. This utility model has the following beneficial effects: 1. This utility model, through a movable component set outside the chamber and an inner frame set inside the chamber, utilizes the magnetic attraction between two magnets separated by the chamber wall, and then drives the movable component to move through a drive mechanism, thereby synchronously moving the inner frame; it solves the problem in the prior art that after scale or moss grows on the inner wall of the detection chamber, it is difficult to effectively clean it while maintaining the chamber's airtightness, thus affecting observation; it achieves the technical effect of automatic, non-contact cleaning of the inner wall without compromising the chamber's airtightness, maintaining the chamber's transparency at all times, and ensuring the observation effect.

[0027] 2. This utility model, by setting up an installation mechanism, includes a first fixed block on the moving block and a second fixed block on the moving frame. A damping rod is used to push the limiting block into the limiting groove of the second fixed block to achieve initial positioning, and then the threaded rod is used to securely lock it. This solves the problems of complex connection and installation, difficult alignment, and low efficiency of the drive component and cleaning component in the prior art. It achieves the effect of quick positioning followed by secure locking, making the installation and disassembly of the entire device extremely convenient, time-saving, and labor-saving, and improving maintenance efficiency.

[0028] 3. This utility model, by setting up a driving mechanism, uses a driving source to drive the threaded rod to rotate, and causes the threaded sliding block to slide up and down along the axial direction of the threaded rod. The sliding block is fixedly connected to the moving block; it solves the problems of low efficiency or unstable driving structure in traditional manual cleaning; it achieves a stable, reliable and easy-to-control linear driving force for the cleaning components, ensuring a smooth and efficient cleaning process.

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.

[0032] Example: Reference Figures 1 to 5 This utility model provides an inner wall cleaning device for a testing box, which aims to solve the problems in the prior art where scale buildup on the inner wall of a transparent testing box affects observation and makes it difficult to clean efficiently while maintaining a tight seal.

[0033] A cleaning device for the inner wall of a testing box includes a bottom shell 1, a box body 2, and a top plate 3. The box body 2 is vertically arranged on the top of the bottom shell 1, and the top plate 3 covers the top of the box body 2. The box body 2 is made of transparent material, and a feed pipe 4 is also provided on the top plate 3.

The drive source 51 is detachably mounted on the motor block 52 by plugging in. The drive mechanism 5 also includes a threaded rod 53 driven to rotate by the drive source 51. The threaded rod 53 is vertically arranged. The drive mechanism 5 also includes a sliding block 54 threadedly engaged with the threaded rod 53. The sliding block 54 slides up and down along the axial direction of the threaded rod 53.

[0037] The device also includes a movable block 7, which is fixedly connected to the sliding block 54, and a mounting mechanism 6 for detachably connecting the movable block 7 to the movable frame 551 of the movable component 55.

[0038] The mounting mechanism 6 includes a first fixed block 61 disposed on the movable block 7, and a second fixed block 62 disposed on the movable frame 551. The second fixed block 62 has a limiting groove. The mounting mechanism 6 also includes a damping rod 63 installed in the first fixed block 61. The mounting mechanism 6 also includes a limiting block 64, which is pushed by the elastic force of the damping rod 63. The limiting block 64 is pluggably engaged with the limiting groove of the second fixed block 62 to achieve rapid initial positioning of the first fixed block 61 and the second fixed block 62. The mounting mechanism 6 also includes a second threaded rod 65, which passes through the first fixed block 61 and is threadedly connected to the second fixed block 62 to achieve a firm lock between the movable block 7 and the movable frame 551.

[0039] In a preferred embodiment, in order to construct the main structure of the detection box, the device also includes a bottom shell 1 and a top plate 3. The box body 2 is vertically arranged on the top of the bottom shell 1, and the top plate 3 is covered on the top of the box body 2, together forming a cavity for containing sewage.

[0040] As a preferred embodiment, in order to facilitate the addition of sewage into the tank 2, the device also includes a feed pipe 4, which passes through the top plate 3 and extends downward into the interior of the tank 2.

[0041] In a preferred embodiment, in order to achieve stable vertical drive, the threaded rod 53 of the drive mechanism 5 is set vertically, and the sliding block 54 slides up and down along the axial direction of the threaded rod 53 through threaded engagement.

[0042] In a preferred embodiment, to facilitate the maintenance or replacement of the drive source 51, the drive source 51 is detachably mounted on the motor block 52 via a plug-in connection.

[0043] In a preferred embodiment, in order to achieve simultaneous cleaning of multiple inner walls of the housing 2, the movable frame 551 has a U-shaped structure and surrounds the three opposite sides of the exterior of the housing 2.

[0044] As a preferred embodiment, in order to facilitate the replacement of worn cleaning parts, the surface of the inner frame 554 facing the inner wall of the housing 2 is detachably equipped with cleaning parts.

[0045] As a preferred embodiment, the housing 2 is made of transparent material to facilitate external observation by the operator.

[0046] The implementation principle of this application embodiment is as follows: the device consists of a bottom shell 1, a box 2, and a top plate 3 forming a detection box. Under the action of the drive mechanism 5, the inner wall of the detection box is cleaned. Under the action of the installation mechanism 6, the cleaning components and the drive are quickly installed.

[0047] First, the operator lets the wastewater enter the tank 2 through the feed pipe 4. Since the tank 2 is transparent, it is convenient for the operator to observe it from the outside.

[0048] Over a long period of observation, it was found that sewage typically contains sludge and suspended solids, causing scale or moss to form on the side walls of the testing chamber after prolonged use. In this case, the operator first uses the installation mechanism 6 to assemble the moving block 7 with the moving component 55. Then, the operator inserts the drive source 51 of the drive mechanism 5 onto the motor block 52, causing the motor block 52 to drive the threaded rod 53 to rotate, thus bringing it into contact with the sliding block 54 and interfering with its movement. Block 54 drives the moving block 7 to move upward, thereby driving the moving frame 551 of the moving component 55 to move upward. However, a magnetic magnet 552 is fixed inside the moving frame 551. The magnetic magnet 552 contacts the magnetic magnet 553 inside the box 2, thereby causing the inner frame 554 to move upward under the action of the magnetic magnet 553. This allows the cleaning parts attached to the surface of the inner frame 554 to clean the inner wall of the box 2, thereby removing scale or moss that has formed on the inner wall of the box 2.

[0049] Then, when the operator installs the moving block 7 and the moving component 55, the operator first contacts the fixing block 61 on the moving block 7 with the fixing block 62 on the moving frame 551, so that the limiting block 64 is inserted into the fixing block 62. Under the action of the damping rod 63, the limiting block 64 is kept in the fixing block 62, so that they are aligned to form a preliminary positioning, making the subsequent installation of the threaded rod 65 more convenient. At this time, the threaded rod 65 is inserted into the fixing block 62, thereby enabling the rapid installation of the driving component and the moving component.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
