Description

A concealed interior wall cleaning device and a water quality monitoring device Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a concealed interior wall cleaning device and a water quality monitoring device having the concealed interior wall cleaning device. Background Technology

[0002] When working equipment is used for a long time or in harsh environments, the inner surfaces of the working environment can become contaminated with pollutants. For example, water quality monitoring equipment floating on a lake consists of a buoyant outer shell and functional components for water quality monitoring. When the equipment floats on the lake for extended periods, algae can easily proliferate on the inner surface of the outer shell, affecting the normal operation of the functional components. Various indoor cleaning devices for working environments have emerged, but these devices often require manual cleaning by the operator, significantly reducing cleaning efficiency. Whether manual or electric, cleaning devices require the user to move them to or near the location of the equipment to be cleaned, increasing transportation costs and creating storage problems. Currently available concealed cleaning devices primarily target functional components and operate mainly in dry environments, lacking in-situ cleaning capabilities for underwater environments. The difficulty of underwater cleaning lies in the inability to clean by rinsing alone, and the necessity of protecting the cleaning equipment. Furthermore, the structures of currently available concealed cleaning devices are relatively complex, occupying space on the equipment to be cleaned during cleaning. Therefore, there is an urgent need to develop a concealed cleaning device that is suitable for underwater environments. Summary of the Invention

[0003] This disclosure aims to address at least one of the technical problems existing in the prior art.

[0004] Therefore, the first aspect of this disclosure provides a concealed interior wall cleaning device that does not affect the functional components of the device to be cleaned during cleaning, and does not occupy too much of the internal space of the device to be cleaned, thus helping users to solve cleaning problems efficiently.

[0005] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0006] The first aspect of this disclosure provides a concealed inner wall cleaning device for cleaning the inner wall of a device to be cleaned. The concealed inner wall cleaning device is arranged in a cavity formed by the inner wall of the device to be cleaned, and includes a first mounting plate, a second mounting plate, a rotary drive component and a spacing adjustment component arranged coaxially with the cavity, and a cleaning brush assembly arranged between the first mounting plate and the second mounting plate.

[0007] Both the first mounting plate and the second mounting plate have gaps between them and the inner wall of the cavity;

[0008] The rotary drive is supported in the cavity, and the output end of the rotary drive is fixedly connected to the first mounting plate. The rotary drive is used to make the first mounting plate rotate about the axis of the cavity.

[0009] The spacing adjustment component is installed between the first mounting plate and the second mounting plate to adjust the spacing between the first mounting plate and the second mounting plate along the axial direction of the cavity, so as to form the working space of the cleaning brush assembly between the first mounting plate and the second mounting plate;

[0010] The cleaning brush assembly is arranged radially along the first mounting plate and includes a base, a brush barrel, a cleaning brush, a third drive motor, and an angle adjustment component. The base is fixed on the first mounting plate. The base and the brush barrel are connected via the angle adjustment component at one end near the axial direction of the cavity. The angle adjustment component is used to adjust the angle between the base and the brush barrel. The third drive motor is used to extend the cleaning brush into or out of the brush barrel and is movably disposed within the brush barrel as the cleaning brush moves.

[0011] In some embodiments, the rotary drive is a rotary motor disposed on the side of the first mounting plate facing away from the second mounting plate. The rotary motor is located at the center of the first mounting plate and has a stator, a first rotating shaft, and a first rotating wheel connected in sequence. The stator is assembled with the cavity. One end of the first rotating shaft is rotatably connected to the stator, and the other end of the first rotating shaft is fixedly connected to the first rotating wheel. A mounting hole is provided on the side of the first mounting plate away from the second mounting plate. The first mounting plate is fixedly connected to the first rotating wheel through the mounting hole, so that the first mounting plate rotates synchronously with the first rotating wheel.

[0012] In some embodiments, the spacing adjustment member includes at least two nested rods and a second drive motor disposed between each adjacent rod. The output shafts of each rod and the second drive motor are coaxially arranged with the cavity. The outermost rod is fixedly connected to the first mounting plate, and one end of the innermost rod is connected to the second mounting plate. The outermost first rod among the adjacent rods is a hollow structure with internal threads. One end of the innermost second rod among the adjacent rods is fixedly connected to the output shaft of the second drive motor through a second rotating wheel with external threads. Under the drive of the second drive motor and the cooperation of the internal and external threads, the second rod extends into or out of the first rod by the threaded compression to form a telescopic rod. During this process, the second drive motor moves inside the first rod as the second rod extends into or out of the first rod.

[0013] In some embodiments, the cleaning brush includes a brush rod and a brush head rotatably connected by a second rotating shaft, the brush barrel is a hollow structure with internal threads, and both the brush rod and the third drive motor are movably disposed within the brush barrel.

[0014] In some embodiments, the brush rod is a single rod or a telescopic rod composed of at least two nested rods. A third drive motor is provided between each adjacent rod. The output shafts of the rods and the third drive motors are coaxially arranged. The outermost third rod among the adjacent rods is a hollow structure with internal threads. The end of the innermost fourth rod, away from the brush head, is fixedly connected to the output shaft of the third drive motor via a third rotating wheel with external threads. Under the drive of the third drive motor and the cooperation of the internal and external threads, the fourth rod extends into or out of the third rod by thread compression, forming a telescopic rod. During this process, the third drive motor moves within the third rod as the fourth rod extends into or out of it.

[0015] In some embodiments, a groove is provided on the side wall of the brush barrel, and a groove is provided on the outer peripheral surface of the brush handle, wherein the groove and the groove are fitted together.

[0016] In some embodiments, an anti-collision post is provided on the brush rod near the brush head to prevent the brush head from touching the second mounting plate during movement. The area on the anti-collision post that contacts the second mounting plate is set as an arc surface to form a rolling contact between the anti-collision post and the second mounting plate.

[0017] In some embodiments, the brush head is made of materials including plastic, hair, steel wire, and sponge; the brush head removes contaminants from the inner wall of the cavity by means of friction, adsorption, discharge, heating, and / or cooling.

[0018] In some embodiments, the angle adjustment component includes a fourth drive motor and a third rotating shaft fixedly connected to the output end of the fourth drive motor. The base has a mounting hole through which the third rotating shaft passes. One end of the brush bucket near the center of the first mounting plate is fixedly connected to the third rotating shaft. The fourth drive motor drives the brush bucket to rotate through the third rotating shaft, thereby changing the angle between the brush bucket and the base.

[0019] A water quality monitoring device is provided in the second aspect of this disclosure, including a housing, an inner wall cleaning device disposed within the housing, and a functional component for realizing water quality monitoring. The inner wall cleaning device is a concealed inner wall cleaning device according to any embodiment of the first aspect of this disclosure, and the functional component is disposed on the side of the first mounting plate or the second mounting plate facing away from the cleaning brush assembly.

[0020] Compared with the prior art, this disclosure has the following advantages and beneficial effects:

[0021] (1) This disclosure is concealed. It is installed at the bottom or top of the equipment to be cleaned and is covered by the first mounting plate and the second mounting plate. It can better conceal the cleaning brush and avoid the problem of carrying or storing the cleaning equipment.

[0022] (2) This invention has a small volume and uses a threaded extrusion telescopic component to allow the cleaning brush assembly to be laid flat inside the equipment to be cleaned when not in operation, thus occupying a small volume of the equipment to be cleaned and having a low height.

[0023] (3) This disclosure can achieve automation. Since it is installed inside the equipment to be cleaned, the cleaning brush can be controlled by a remote transmission device, eliminating the need for manual cleaning and improving cleaning efficiency.

[0024] (4) This disclosure can realize the automatic cleaning of the inner wall of underwater equipment, and solve the problem of underwater equipment being blocked by water pollution, algae bloom, algae and other underwater equipment. Attached Figure Description

[0046] The present application will be further described below with reference to the implementation methods and an embodiment provided in Figures 1 to 9.

[0047] Referring to Figures 1-3, this embodiment of the present disclosure provides a concealed inner wall cleaning device for cleaning the inner wall of a device to be cleaned. The inner wall of the device to be cleaned is cylindrical. The concealed inner wall cleaning device of this embodiment is disposed within a cavity 10 formed by the inner wall of the device to be cleaned. It includes a first mounting plate 20, a second mounting plate 30, a rotary drive component 40, and a spacing adjustment component 50, all coaxially arranged with the cavity 10, and a cleaning brush assembly 60 disposed between the first mounting plate 20 and the second mounting plate 30.

[0048] Both the first mounting plate 20 and the second mounting plate 30 have gaps between them and the inner wall of the cavity 10;

[0049] The rotary drive 40 is supported on the cavity 10, and the output end of the rotary drive 40 is fixedly connected to the first mounting plate 20. The rotary drive 40 is used to make the first mounting plate 20 rotate about the axis of the cavity 10.

[0050] The spacing adjustment component 50 is installed between the first mounting plate 20 and the second mounting plate 30 to adjust the spacing between the first mounting plate 20 and the second mounting plate 30 along the axial direction of the cavity 10, so as to form the working space of the cleaning brush assembly 60 between the first mounting plate 20 and the second mounting plate 30.

[0051] The cleaning brush assembly 60 is arranged radially along the first mounting plate 20 and includes a base 61, a brush barrel 62, a cleaning brush 63, a third drive motor 64, and an angle adjustment component 65. The base 61 is fixed on the first mounting plate 20. The base 61 is connected to one end of the brush barrel 62 near the cavity 10 axially via the angle adjustment component 65. The angle adjustment component 65 is used to adjust the angle between the base 61 and the brush barrel 62. The third drive motor 64 is disposed inside the brush barrel 62 and is used to extend or extend the cleaning brush 63 into or out of the brush barrel 62.

[0052] In this embodiment, the first mounting plate 20 mainly serves to support the spacing adjustment member 50 and the cleaning brush assembly 60 in the cleaning equipment of this embodiment. The second mounting plate 30 mainly serves to isolate the functional components in the cleaning equipment that do not need to be cleaned (these functional components are not shown in the figure). The functional components in the cleaning equipment are placed on the side of the second mounting plate 30 facing away from the first mounting plate 20, so as to avoid the adverse effects caused by the cleaning brush assembly 60 working on the functional components in the cleaning equipment that do not need to be cleaned. The first mounting plate 20 and the second mounting plate 30 are arranged at an axial distance along the cavity 10 (in Figures 1 to 4, the first mounting plate 20 is located below the second mounting plate 30). The first mounting plate 20 and the second mounting plate 30 are driven by the rotation drive member 40 and the spacing adjustment member 50, respectively, and can move relative to the cavity 10. In order to ensure that the movement of the first mounting plate 20 and the second mounting plate 30 in the cavity 10 is not obstructed, the first mounting plate 20 and the second mounting plate 30 are not connected to or in contact with the inner wall of the cavity 10. Preferably, the first mounting plate 20 and the second mounting plate 30 are both circular plates with a radius slightly smaller than the radius of the cavity 10.

[0053] In this embodiment, referring to Figure 4, the rotary drive 40 is a rotary motor (specifically, a stepper motor or a servo motor) disposed on the side of the first mounting plate 20 facing away from the second mounting plate 30, and the rotary motor is located at the center of the first mounting plate 20, having a stator 41, a first rotating shaft 42, and a first rotating wheel 43 connected in sequence. The stator 41 forms an assembly relationship with the cavity 10. Specifically: when a base plate 11 is provided in the cavity 10, the stator 41 is fixed at the center of the base plate 11 of the cavity 10, thereby fixing the relative position of the rotary motor and the cavity 10; when a base plate 11 is not provided in the cavity 10, the stator 41 is fixedly connected to the inner wall of the cavity 10 through a support member. One end of the first rotating shaft 42 is rotatably connected to the stator 41, and the other end of the first rotating shaft 42 is fixedly connected to the first rotating wheel 43. A mounting hole is provided on the side of the first mounting plate 20 away from the second mounting plate 30. The first mounting plate 20 is fixedly connected to the first rotating wheel 43 through the mounting hole, so that the first mounting plate 20 rotates synchronously with the rotation of the first rotating wheel 43. The first rotating wheel 43 increases the stability between the first rotating shaft 42 and the first mounting plate 20.

[0054] In this embodiment, the spacing adjustment member 50 includes at least two nested rods and a second drive motor 51 disposed between each adjacent rod. The output shafts of each rod and the second drive motor 51 are coaxially arranged with the cavity 10. The outermost rod is fixedly connected to the first mounting plate 20, and one end of the innermost rod is connected to the second mounting plate 30. (This connection method can be set as a fixed connection or a rotating connection according to the application requirements of the equipment to be cleaned. For example, when the second mounting plate 30 does not need to rotate horizontally around the cavity 10, a bearing can be set at the connection between the innermost rod and the second mounting plate 30, that is, the rod only causes the second mounting plate 30 to move along the cavity axial direction and not to rotate around the cavity axial direction; when the second mounting plate 30 needs to rotate horizontally around the cavity 10, the innermost rod is fixedly connected to the second mounting plate 30, that is, the rod causes the second mounting plate 30 to move along the cavity axial direction and rotate around the cavity axial direction at the same time.) The first rod 53, located on the outer side of the adjacent rods, is a hollow structure with internal threads. One end of the second rod 52, located on the inner side of the adjacent rods, is fixedly connected to the output shaft of the second drive motor 51 via a second rotating wheel 511 with external threads. Under the drive of the second drive motor 51 and the cooperation of the internal and external threads, the second rod 52 extends into or out of the first rod 53 by thread compression, forming a telescopic rod. During this process, since the second drive motor 51 is fixedly connected to one end of the second rod 52, it also moves within the first rod 53 as the second rod 52 extends into or out of the first rod 53. It can be understood that the spacing adjustment component 50, composed of multiple rods nested around a central axis and multiple movable second drive motors, provided in this embodiment, can provide a larger telescopic distance while having the same retracted size (i.e., the size corresponding to all second rods when all second rods are retracted into the first rod).

[0055] In a specific embodiment of this application, referring to Figures 2 and 4, the spacing adjustment component 50 includes a second drive motor 51 and a telescopic rod consisting of an inner rod 52 and an outer rod 53 nested together. The outer rod 53 is a hollow structure with internal threads and is fixed at the center of the first mounting plate 20. The axial direction of the outer rod 53 coincides with the axial direction of the first mounting plate 20. The inner rod 52 and the second drive motor 51 are both movably disposed within the outer rod 53. A second rotating wheel 511 with external threads that mates with the internal threads of the outer rod 53 is fixedly sleeved on the output end of the second drive motor 51. The second rotating wheel 511 is fixedly connected to one end of the inner rod 52, and the other end of the inner rod 52 is fixedly connected to the side of the second mounting plate 30 facing the first mounting plate 20. When the second drive motor 51 rotates forward, the threaded engagement between the second rotating wheel 511 and the outer rod 53 generates a pushing force on the inner rod 53, causing the inner rod 52 to extend out of the outer rod 53. This causes the second mounting plate 30 to move away from the first mounting plate 20, thus increasing the axial distance between the first mounting plate 20 and the second mounting plate 30 in the cavity 10. When the second drive motor 51 rotates in reverse, the threaded engagement between the second rotating wheel 511 and the outer rod 53 generates a pulling force on the inner rod 52, causing the inner rod 52 to retract into the outer rod 53. This causes the second mounting plate 30 to move closer to the first mounting plate 20, thus decreasing the axial distance between the first mounting plate 20 and the second mounting plate 30 in the cavity 10.

[0056] In this embodiment, referring to Figures 5 and 6, the base 61 of the cleaning brush assembly 60 is fixed to the side of the first mounting plate 20 facing the second mounting plate 30. The base 61 is generally L-shaped, with the vertical section of the base 61 located near the center of the first mounting plate 20. A pressure block 611 is provided at one end of the base 61 away from the center of the first mounting plate 20. When the cleaning brush assembly 60 is not in operation, the end of the brush bucket 62 away from the center of the first mounting plate 20 is placed on the pressure block 611. The dimensions of the pressure block 611 and the vertical section of the base 61 along the axial direction of the cavity 10 should ensure that when the cleaning brush assembly 60 is not in operation, the horizontal section of the base 61 is parallel to the axial direction of the brush bucket 62, and the distance between the horizontal section of the base 61 and the brush bucket 62 is as small as possible, so that the cleaning device of this embodiment occupies as little internal space as possible in the device to be cleaned.

[0057] In this embodiment, referring to Figures 5 to 8, the cleaning brush 63 in the cleaning brush assembly 60 includes a brush rod 631 and a brush head 632 rotatably connected by a second rotating shaft 633. The brush barrel 62 is a hollow structure with an internal thread 621. Both the brush rod 631 and the third drive motor 64 are movably disposed inside the brush barrel 62. Similar to the spacing adjustment component 50, the brush rod 631 in the cleaning brush assembly 60 is a single rod or a telescopic rod composed of at least two rods nested in sequence. A third drive motor 64 is provided between each adjacent rod. The output shafts of each rod and the third drive motor 64 are coaxially arranged. The third rod located on the outer side of the adjacent rods is a hollow structure with internal threads. The end of the fourth rod located on the inner side of the adjacent rods away from the brush head 632 is fixedly connected to the output shaft of the third drive motor 64 through a third rotating wheel 641 with external threads. Under the drive of the third drive motor 64 and the cooperation of the internal and external threads, the fourth rod extends into or out of the third rod by the thread compression, forming a telescopic rod. During this process, since the third drive motor 64 is fixedly connected to one end of the fourth rod, it also moves inside the third rod as the fourth rod extends into or out of the third rod. In one specific embodiment of this application, the brush rod 631 has only one rod, the end of which, away from the brush head 632, is fixedly connected to the output shaft of the third drive motor 64 via a third rotating wheel 641 with external threads. The brush head 632 is made of materials including but not limited to plastic, hair, steel wire, and sponge. When the third drive motor 64 rotates forward, the threaded engagement between the third rotating wheel 641 and the internal thread 621 of the brush barrel generates a pushing force on the brush rod 631, causing it to extend out of the brush barrel 62 until the brush head 632 abuts against or approaches the inner wall of the cavity 10; when the third drive motor 64 rotates in reverse, the threaded engagement between the third rotating wheel 641 and the internal thread 621 of the brush barrel generates a pulling force on the brush rod 631, causing it to retract into the brush barrel 62.

[0058] Furthermore, the interaction between the brush head 632 and the inner wall of the cavity 10 is not limited to friction. By changing the material and cleaning method of the brush head 632, the brush head 632 can remove contaminants on the inner wall of the cavity 10 through adsorption, discharge, heating and / or cooling and spraying liquid.

[0059] Furthermore, a groove 622 is provided on the side wall of the brush barrel 62, and a protrusion 634 is provided on the outer peripheral surface of the brush rod 631. The groove 622 and the protrusion 634 fit together so that the brush rod 631 will not rotate around its own center during movement, thereby ensuring that the brush rod 631 can move in a straight line inside the brush barrel 62.

[0060] Furthermore, an anti-collision post 635 is provided on the brush handle 631 near the brush head 632 to prevent the brush head 632 from contacting the second mounting plate 30 during movement, thereby avoiding impact on the functional components in the equipment to be cleaned. Preferably, the area on the anti-collision post 635 that contacts the second mounting plate 30 is set as an arc surface 635a to form a rolling contact between the anti-collision post 635 and the second mounting plate 30, thereby reducing friction between the anti-collision post 635 and the second mounting plate 30 and extending the service life of the anti-collision post 635 and the second mounting plate 30.

[0061] In this embodiment, referring to Figure 9 (it should be noted that Figure 9 only schematically shows a partial structure of the brush barrel 62 and the base 61, and is intended to illustrate the assembly relationship between the angle adjustment component 60 and the brush barrel 62 and the base 61), the angle adjustment component 65 in the cleaning brush assembly 60 includes a fourth drive motor 651 and a third rotating shaft 652 fixedly connected to the output end of the fourth drive motor 651. The vertical section of the base 61 is provided with a mounting hole 612 for the third rotating shaft 652 to pass through. One end of the brush barrel 62 near the center of the first mounting plate 20 is fixedly connected to the third rotating shaft 652. The fourth drive motor 651 drives the third rotating shaft 652, thereby driving the brush barrel 62 to rotate, thereby changing the included angle between the brush barrel 62 and the base 61.

[0062] Preferably, each drive motor is a stepper motor or a servo motor, which can lock the corresponding rotating shaft, or generate a driving force to rotate the rotating shaft even when the corresponding rotating shaft is stationary, so that the brush head 632 fits against the inner wall of the cavity 10 and generates a stable interaction force.

[0063] It is understood that multiple cleaning brush assemblies 60 may be provided between the first mounting plate 20 and the second mounting plate 30 as needed, and all cleaning brush assemblies 60 are arranged radially along the axis of the first mounting plate 20.

[0064] Optionally, the concealed interior wall cleaning device of this embodiment can be used in conjunction with an external control terminal and automation device to achieve remote cleaning and timed automatic cleaning.

[0065] The working process of the cleaning equipment provided in this embodiment is as follows:

[0066] When not in use, as shown in Figures 2 and 5, all components in the cleaning device of this embodiment are in their initial state, that is, the brush bucket 62 is placed flat on the base 61 and rests against the pressure block 611 of the base 61, the cleaning brush 63 is retracted into the brush bucket 62, and the distance between the first mounting plate 20 and the second mounting plate 30 is the minimum distance that the two can achieve.

[0067] When using it, see Figures 3 and 6:

[0068] The second drive motor 51 inside the spacing adjustment component 50 rotates forward. Through the cooperation between the external thread of the second rotating wheel 511 and the internal thread of the outer rod 53, the inner rod 52 is pushed out from the outer rod 53, thereby pushing the second mounting plate 30 to the designated position, thus forming the working space of the cleaning brush assembly 60 between the first mounting plate 20 and the second mounting plate 30.

[0069] The fourth drive motor 651 inside the angle adjustment component 65 drives the third rotating shaft 652 to rotate according to the set angle, lifting the brush bucket 62, thereby changing the angle between the brush bucket 62 and the base 61;

[0070] The third drive motor 64 rotates forward, and through the cooperation between the external thread of the third rotating wheel 641 and the internal thread 621 of the brush bucket, the cleaning brush 63 is pushed out of the brush bucket 62 until the brush head 632 contacts the inner wall of the cavity 10.

[0071] The second rotating shaft 633 rotates, changing the angle between the brush rod 631 and the brush head 632;

[0072] By adjusting the angle between the brush barrel 62 and the base 61, the cleaning brush 63 extends a certain distance from the brush barrel 62, and the angle between the brush handle 631 and the brush head 632 is adjusted, so that the brush head 632 reaches the inner wall of the cavity 10 that needs to be cleaned, and moves up and down near the inner wall of the cavity 10, sweeping away contaminants through squeezing and friction against the inner wall.

[0073] When the brush head 632 needs to move left or right, that is, to make horizontal circular motion within the cavity 10, the rotary drive 40 is activated. The first rotating shaft 42 of the rotary drive 40 drives the first rotating wheel 43, which in turn drives the first mounting plate 20 to rotate. The first mounting plate 20 drives the base 61 to rotate, and the base 61 drives the brush bucket 62 and the cleaning brush 6 to rotate, thereby causing the brush head 632 to make horizontal circular motion within the cavity 10. Through the squeezing and friction against the inner wall, contaminants are swept away.

[0074] When use or cleaning is finished, the rotary drive 40 stops operating, and the third drive motor 64 in the cleaning brush assembly 60 reverses, retracting the cleaning brush 63 into the brush holder 62. The second drive motor 51 in the spacing adjustment assembly 50 reverses, retracting the inner rod 52 into the outer rod 53, thereby moving the second mounting plate 30 closer to the first mounting plate 20. By adjusting the angle between the brush holder 62 and the base 61, the retraction distance between the cleaning brush 63 and the brush holder 62, and the angle between the brush rod 631 and the brush head 632, the brush holder 62 is placed flat on the base 61, returning to its initial state.

[0075] In summary, this disclosure provides a concealed internal wall cleaning device for cleaning the inner wall of a cylinder. This cleaning device is applicable to both ground-based and underwater installations. The working principle of this cleaning device involves a motor driving the angle and length of a telescopic rod. The rod's extension and retraction are achieved through threaded compression. By adjusting the angle and length of the telescopic rod, cleaning at different heights is achieved. A rotating motor drives the first mounting plate to rotate, enabling 360-degree horizontal cleaning of the inner wall.

[0076] A water quality monitoring device provided in a second aspect of this disclosure includes a housing, an inner wall cleaning device disposed within the housing, and a functional component for realizing water quality monitoring. The inner wall cleaning device is a concealed inner wall cleaning device provided in a first aspect of this disclosure. The functional component is disposed on the side of a first mounting plate or a second mounting plate facing away from the cleaning brush assembly.
