[0045] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 4 As shown, the embodiment of the present disclosure provides a device for cleaning impurities on the surface of a window sheet. The window sheet 1 is located on a detection device 2, a positioning track 21 is provided on the upper part of the detection device 2, and the device is used for underwater operation. The device comprises: a closed chamber 3, a power device 4, a transmission device 5 and a scraper device 6. The power device 4 is arranged in the closed chamber 3; the transmission device 5 is arranged in the closed chamber 3 and connected to the power device 4 so as to perform rotational motion under the drive of the power device 4; the scraper device 6 is connected to the transmission device 5 so as to perform linear reciprocating motion along the positioning track 21 under the action of the transmission device 5.

[0047] Specifically, the device for cleaning impurities on the surface of the window piece is applied to a detection device 2 having a window piece 1. The detection device 2 is preferably a sensor. The detection device 2 is generally used in underground sealed environments, ships and other scenes. Preferably, for example, pipes and sewers under the manhole cover. The closed chamber 3 is used to provide a sealed environment, and its waterproof level can reach IP68 waterproof level. The power device 4 is located in the closed chamber 3 to provide power for the transmission device 5. The transmission device 5 is also located in the closed chamber 3 and can transmit the rotational motion to the scraper device 6. The scraper device 6 can convert the rotational motion into a linear reciprocating motion along the positioning track 21, thereby providing a cleaning function for the measuring chamber of the detection device.

[0048] Preferably, the power device 4 is a motor, in particular a mini motor, which takes up little space and has low cost, but can provide sufficient power for the entire mechanism.

[0049] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the transmission device 5 includes a transmission shaft 51, a first gear 52 and a second gear 53. The transmission shaft 51 is rotatably disposed in the closed chamber 3 through a positioning bearing 54; the first gear 52 is disposed on the output shaft of the power device 4; the second gear 53 is disposed at one end of the transmission shaft 51 and meshes with the first gear 52; wherein, the transmission shaft 51 is located at one end of the second gear 53 and passes through the closed chamber 3 to connect with the scraper device 6.

[0050] Specifically, the first gear 52 is set to one end of the output shaft of the mini motor, and the second gear 53 is set to one end of the transmission shaft 51. The two are meshed with each other. There are many ways to set the two gears and the shaft, such as key connection, tooth connection, spline connection, cone connection, thread connection, involute connection, etc. The transmission shaft 51 can be set on the inner wall of the closed chamber 3 through one or more positioning bearings 54. Thereby, the rotation along its own axis is not affected, and the rotation can be transmitted to the scraper device 6.

[0051] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the number of teeth of the second gear 53 is greater than the number of teeth of the first gear 52 .

[0052] Specifically, when the mini motor is working, it drives the first gear 52 with fewer teeth to rotate, and since the second gear 53 is meshed with the first gear 52, it also drives the second gear 53 with more teeth to rotate. Thus, the gear set amplifies the torque transmitted to the transmission shaft 51 by the mini motor.

[0053] like Figures 1 to 4As shown, in a specific embodiment of the present disclosure, the scraper device 6 includes a transmission rod 61 and a scraper 62. One end of the transmission rod 61 is connected to the transmission shaft 51 to rotate along with the transmission shaft 51. The scraper 62 is connected to the other end of the transmission rod 61 and is positioned in the positioning track 21 to perform linear reciprocating motion along the positioning track 21 under the drive of the transmission rod 61.

[0054] Specifically, the scraper device 6 can convert the rotational motion of the transmission shaft 51 into a linear reciprocating motion. Preferably, the transmission rod 61 can rotate along with the transmission shaft 51 because it is connected to the transmission shaft 51. At the same time, the transmission rod 61 transmits the rotational motion to the scraper 62, and the scraper 62 depends on its own structure and is restricted by the positioning track 21, so that it can perform linear reciprocating motion in the positioning track 61.

[0055] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the transmission rod 61 includes: a transmission rod 611 and a sliding roller 612 , wherein one end of the transmission rod 611 is connected to the transmission shaft 51 , and the other end is fixedly connected to the sliding roller 612 .

[0056] Specifically, the transmission rod 611 can be arranged parallel to the bottom surface of the sealed chamber 3. There is also a certain distance between the transmission rod 611 and the bottom surface of the sealed chamber 3 to facilitate rotation. The sliding roller 612 is fixed to the other end of the transmission rod 611 away from the transmission shaft 51. The shape of the sliding roller 612 is preferably cylindrical, spherical, etc.

[0057] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the scraper 62 includes a scraper mounting block 621, at least two rollers 622 and two elastic scrapers 623. A slide groove 6211 is provided on the upper portion of the scraper mounting block 621, wherein the sliding roller 612 is arranged in the slide groove 6211 to perform linear reciprocating motion in the slide groove 6211. At least two rollers 622 are arranged on both sides of the slide groove 6211 and are clamped on the positioning track 21; two elastic scrapers 623 are arranged on both sides of the scraper mounting block 621.

[0058] Specifically, the scraper 62 can be an inverted U-shaped structure. The main part of the scraper 62 is the scraper mounting block 621, and the shape of the scraper mounting block 621 is similar to that of the scraper 62, and can also be an inverted U-shaped structure. A slide groove 6211 is provided on the top crossbar of the scraper mounting block 621. The slide groove 6211 is preferably a long strip groove along the length direction of the top crossbar. The sliding roller 612 is just stuck in the slide groove 6211. The transmission rod 611 drives the sliding roller 612 to rotate, and due to the limitation of the slide groove 6211, the sliding roller 612 can make a linear reciprocating motion along the slide groove 6211. As a result, the scraper mounting block 621 can make a linear reciprocating motion along the positioning track 21 under the dual action of the sliding roller 612 and the roller 622 plus the positioning track 21. The number of rollers 622 is preferably an even number, such as 2, 4, 6, 8, etc. They are symmetrically arranged on both sides of the top of the scraper mounting block 621, and there is a gap between them so as not to affect each other's rotation. The scraper mounting block 621 is symmetrically provided with openings on both sides, and two elastic scrapers 623 are symmetrically arranged in the openings on both sides of the scraper mounting block 621. The elastic scraper 623 can make linear reciprocating motion with the scraper mounting block 621. The elastic scraper 623 will intermittently contact and bend the corresponding window sheet 1, and remove the dirt on the surface of the latter through the pressure generated by the deformation of the elastic scraper 623, and when it is separated from the surface of the window sheet 1, the elastic scraper 623 is deformed and restored to throw it off its surface. This reciprocating process continues until the mini motor stops running.

[0059] like Figure 5 As shown, in a specific embodiment of the present disclosure, the transmission device 5 also includes a third gear 55, a connecting shaft 56, a gear set mounting seat 57 and a fourth gear 58, the third gear 55 is arranged at the other end of the transmission shaft 51; the connecting shaft 56 is fixedly connected to the detection device 2; the gear set mounting seat 57 is rotatably arranged on the connecting shaft 56 through a gear set bearing 59; the fourth gear 58 is arranged on the gear set mounting seat 57; wherein the third gear 55 vertically meshes with the fourth gear 58 to drive the gear set mounting seat 57 to rotate.

[0060] Specifically, the third gear 55 is sleeved on the outer side of the other end of the transmission shaft 51 and can rotate with the transmission shaft 51. The connecting shaft 56 can be fixed to the detection device 2 by screws. And the axis of the connecting shaft 56 is perpendicular to the axis of the transmission shaft 51. In this way, the third gear 55 vertically meshes with the fourth gear 58 and can convert the rotational motion of the transmission shaft 51 into the horizontal circular motion of the fourth gear 58 installed on the connecting shaft 56. At the same time, the gear set mounting seat 57 also performs horizontal circular motion with the fourth gear 58. In this case, one end of the transmission rod 611 is connected to the gear set mounting seat 57 and performs horizontal circular motion with the gear set mounting seat 57.

[0061] like Figure 5As shown, in a specific embodiment of the present disclosure, the ratio of the number of teeth of the fourth gear 58 to the number of teeth of the third gear 55 is 2:1.

[0062] Specifically, in order to achieve a better torque amplification effect, the ratio of the number of teeth of the fourth gear 58 to the number of teeth of the third gear 55 is preferably 2:1.

[0063] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the sealed chamber 3 includes a first sealed chamber shell 31 and a first sealing plate 32. The first sealed chamber shell 31 is closed on all sides and has a top opening 311 and a first bottom opening 312; the first sealing plate 32 is covered on the top of the first sealed chamber shell 31 to seal the top of the first sealed chamber shell 31.

[0064] Specifically, the first sealed shell 31 can be a rectangular or cube shell, and its top and bottom are open. It can also be considered that the first sealed shell 31 is formed by surrounding four side panels, or is integrally formed. The first sealed shell 31 is the main installation platform. The size of the first sealing plate 32 matches the top opening 311 of the first sealed shell 31, and can be covered to the top opening 311 of the first sealed shell 31 after the internal components are installed to seal it.

[0065] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the device for cleaning impurities on the surface of the window sheet further includes: a first sealing ring 33, a second sealing ring 34 and a rotating sealing ring 35. The first sealing ring 33 is disposed at the top opening 311 of the first sealed housing 31 to enhance the sealing between the top opening 311 and the first sealing plate 32. The second sealing ring 34 is disposed at the first bottom opening 312 of the first sealed housing 31, and the second sealing ring 34 includes a first through hole 341, and the transmission shaft 51 passes through the first through hole 341 and is connected to one end of the transmission rod 611; the rotating sealing ring 35 is disposed between the transmission shaft 51 in the first through hole 341 and the second sealing ring 34 to enhance the sealing between the transmission shaft 51 and the second sealing ring 34.

[0066] Specifically, both the first sealing ring 33 and the second sealing ring 34 can be plate-shaped sealing rings. The first sealing ring 33 cooperates with the first sealing plate 32 to seal the top opening 311 of the first closed housing 31. The second sealing ring 34 seals the first bottom opening 312 except for its own first through hole 341. The end of the transmission shaft 51 extends out of the first through hole 341 and is connected to the transmission rod 611, and a rotating dynamic seal can be achieved between the transmission shaft 51 and the first through hole 341 through the rotating sealing ring 35. In other words, the rotating sealing ring 35 isolates the gas passage between one end of the gear on the transmission shaft 51 and one end of the fixed transmission rod 611. The first closed housing 31, the first sealing plate 32, the first sealing ring 33, the second sealing ring 34 and the rotating sealing ring 35 form a closed space that can achieve IP68 waterproof capability, and the energy loss caused by the rotation of the transmission shaft 51 is small.

[0067] In a specific embodiment of the present disclosure, the sealed chamber 3 includes: a second sealed chamber shell, a second sealing plate and a sealing ring. The second sealed chamber shell includes a second bottom opening; the second sealing plate is covered at the bottom of the second sealed chamber shell to seal the second sealed chamber shell, wherein a second through hole is opened on the second sealing plate, and the transmission shaft passes through the second through hole so that the third gear can be set at the end of the transmission shaft.

[0068] Specifically, the four side surfaces and the top surface of the second sealed housing are all closed. The top surface is the side of the second sealed housing away from the scraper device 6. The second sealing plate cooperates with the sealing ring to completely seal the second bottom opening of the second sealed housing, and can achieve IP68 waterproof capability.

[0069] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the device also includes an optical coupling control device 7, which is arranged on the transmission shaft 51 and is used to control the start and stop of the power device 4 according to the output end position state of the transmission shaft 51.

[0070] Specifically, the optical coupling control device 7 is a control component of the device, which controls the operation of the mini motor by detecting the position state of the output end of the transmission shaft 51, thereby controlling the movement of the entire mechanism.

[0071] like Figures 1 to 4 As shown, in a specific embodiment of the present disclosure, the optical coupling control device 7 includes a slotted optical coupler 71, a light shielding sheet 72 and a controller. The slotted optical coupler 71 is arranged in the sealed chamber 3; the light shielding sheet 72 is arranged at one end of the transmission shaft 51 to periodically pass through the light path of the slotted optical coupler 71; the controller is connected to the power device 4 and the slotted optical coupler 71, and is used to receive the on-off signal of the slotted optical coupler 71 to determine the position state of the output end of the transmission shaft 51.

[0072] Specifically, the slot-type optical coupler 71 is fixed to the inner wall of the sealed chamber 3. The light shielding sheet 72 is located on the transmission shaft 51 on one side of the slot-type optical coupler 71, and rotates synchronously with the transmission shaft 51. The slot-type optical coupler 71 is shielded once in each rotation cycle. The slot-type optical coupler 71 outputs an electrical signal to the controller. The controller is set with a corresponding program, which will determine the position state of the output end of the transmission shaft 51 and control the start and stop of the mini motor.

[0073] The device for cleaning impurities on the surface of the window piece disclosed in the present invention is responsible for the surface cleaning task of the window piece 1 set on both sides of the gas boundary of the detection device 2, especially for dealing with interferences such as water stains and particles attached to the window piece 1. It has the ability to complete two cleaning actions on the surface of the gas boundary window piece 1 within 5 seconds, has an average power consumption performance of ≤0.15W, has the ability to process two windows 1 at the same time, has the ability to self-reset when power is off, and has IP68 waterproof capability.

[0074] The transmission device 5 disclosed herein converts the electric energy of the mini motor into the energy required for the decontamination action on the window sheet 1 to a large extent. At the same time, the transmission device 5 can complete an action cycle in a shorter time, further reducing energy consumption. The designed sealing measures ensure that the motor is in a safe state underwater while generating low energy loss to the output shaft. Therefore, the disclosure has the characteristics of low power consumption and completes the cleaning work of the window sheet with less power consumption.

[0075] The gear set of the device can amplify the torque of the motor, thereby avoiding the jamming phenomenon caused by the large static friction at startup caused by the rotary dynamic seal. The first sealed housing 31, the first sealing plate 32, the first sealing ring 33, the second sealing ring 34 and the rotary sealing ring 35 can cooperate to achieve IP68 waterproof capability, solving the sealing problem of the open area caused by the assembly process. It can also achieve a rotary dynamic seal on the output end of the transmission shaft 51.

[0076] Under the action of the transmission shaft 51, the transmission rod 611, the sliding roller 612 and the scraper mounting block 621, the rotational motion of the motor output shaft is converted into the linear reciprocating motion of the scraper mounting block 621, thereby driving the low-friction elastic scraper 623 to move linearly and reciprocatingly.

[0077] The shading sheet 72 rotates one circle with the transmission shaft 51, shielding the slotted optical coupler 71 once.
