Description

[0002] The monitoring device can perform real-time monitoring all day long without interruption, and can store monitoring pictures in real time.

Through the monitoring device, the geographical restriction can be broken, the situation of the control area can be remotely mastered, the mobile detection can be realized, and the cost of manual defense can be saved. The monitoring device needs to be installed in the monitored place when in use, and in order to have a wider monitoring field of view, the monitoring device is usually set high. The monitoring lens of the monitoring device will be attached with dust and other substances that interfere with monitoring after long-time use, which is not conducive to image acquisition.

[0003] The cleaning of the monitoring lens is generally carried out by cleaning personnel on site through cleaning tools.

This cleaning method has a safety hazard of falling of the cleaning personnel, and the cleaning efficiency is also low.

[0035] The technical solutions of the present application will be further described below in conjunction with the embodiments and drawings.

[0036] Referring to Figure 1 The first aspect of the present application provides a cleaning mechanism 20 which can effectively clean the monitoring lens 101, eliminate manual cleaning, improve safety, and also enhance the cleaning effect of the monitoring lens 101 and improve the cleaning efficiency.

[0037] The cleaning mechanism 20 includes a transmission member, an elastic sheet and a cleaning member. One end of the elastic sheet is connected to the transmission member, so that the transmission member can drive the elastic sheet to move. The cleaning member is connected to the end of the elastic sheet away from the transmission member. There is an elastic force at the end of the elastic sheet connected to the cleaning member. The elastic force can be converted into pressure on the cleaning member, so that the cleaning member can be tightly attached to the surface to be cleaned. When the elastic sheet moves, it can drive the cleaning member to move, so that the cleaning member can clean the surface to be cleaned.

[0038] It can be understood that the elastic sheet can allow a certain range of deformation, and can automatically recover to the original state after deformation, thereby generating an elastic force. In the cleaning mechanism 20 of the present embodiment, the elastic force of the elastic sheet can be converted into pressure on the cleaning member, so that the cleaning member can be tightly attached to the surface to be cleaned. Since the cleaning member is tightly attached to the surface to be cleaned under the action of the pressure, not only the contact area between the cleaning member and the surface to be cleaned is increased, but also the friction between the cleaning member and the surface to be cleaned is appropriately increased when the cleaning member moves, so that the cleaning member can more easily remove dust and stains on the surface to be cleaned, enhance the cleaning effect and improve the cleaning efficiency.

[0039] It should be noted that the pressure exerted by the elastic sheet on the cleaning member should not be too large, and the cleaning member can be tightly attached to the surface to be cleaned. Otherwise, it will be difficult to drive the cleaning member to move when the transmission member is driven, which is not conducive to cleaning.

[0040] In some embodiments, the elastic piece is an elastic steel piece made of stainless steel, one end of the elastic steel piece is movably connected to the transmission member, and the other end of the elastic steel piece is connected to the cleaning member.

[0041] It can be understood that the elastic piece can also be other structures having the ability of shape deformation and reset, which will not be described here.

[0042] In some embodiments, the cleaning member is provided with at least two connection points along the length direction thereof to be connected to the elastic piece. Such a structure can position the cleaning member, so that the cleaning member can be effectively prevented from rotating when moving for cleaning.

[0043] For example, the cleaning member is provided with two connection points along the length direction thereof to be connected to the elastic piece. Of course, it can be conceived that the number of connection points between the elastic piece and the cleaning member can also be three, four, five, or more, which will not be specifically limited here.

[0044] In some embodiments, the elastic piece is arc-shaped, which is more conducive to converting the elastic force of the elastic piece into pressure on the cleaning member. Further, the elastic piece is an arc-shaped elastic steel piece 207.

[0045] Of course, in other embodiments, the elastic piece can also be provided in a bent shape or other irregular shape, which can provide pressure to make the cleaning member closely contact the surface to be cleaned.

[0046] It can be conceived that the transmission member can be a transmission elastic piece moving along the length direction of the transmission member, thereby driving the cleaning member to move along the length direction of the transmission member to achieve cleaning. It can also be a transmission elastic piece rotating, thereby driving the cleaning member to swing to achieve cleaning. It can also be other transmission modes that can drive the elastic piece to move, thereby driving the cleaning member to move for cleaning.

[0047] Hereinafter, the case of “the transmission member driving the elastic piece to move along the length direction of the transmission member, thereby driving the cleaning member to move along the length direction of the transmission member to achieve cleaning” will be further described.

[0048] In some embodiments, the cleaning mechanism 20 further comprises a driving block 204 and a moving block 205, the driving block 204 is movably arranged on the transmission member, and the driving block 204 is connected to the elastic piece through the moving block 205.

[0049] Referring to Figure 1 , one end of the elastic piece is connected to the moving block 205, and the other end of the elastic piece away from the moving block 205 is provided with two connection points along the length direction of the elastic piece to be connected to the cleaning member.

[0050] In some of the embodiments, the transmission member is a reciprocating screw 203, the reciprocating screw 203 is provided with two symmetrical and intersecting helical grooves along the length direction thereof, both ends of the two helical grooves are communicated, and the driving block 204 is slidably arranged in the helical grooves. When the reciprocating screw 203 rotates, the driving block 204 slides in the helical grooves, and then the elastic sheet is moved back and forth along the length direction of the reciprocating screw 203 through the linear transmission of the moving block 205. The driving block 204 is rotatably connected to the moving block 205 to reduce the sliding friction between the reciprocating screw 203 and the driving block 204.

[0051] It can be understood that in another embodiment, the transmission member is provided with a screw thread along the length direction thereof, the driving block 204 is provided with a threaded hole, and the transmission member is arranged in the threaded hole of the driving block 204 and cooperates with the threaded hole, so that the transmission member can linearly drive the driving block 204 to move back and forth along the length direction of the transmission member when the transmission member rotates. The transmission member can be a screw, a ball screw, or other transmission members having a linear transmission function.

[0052] In yet another embodiment, the transmission member includes a guide rail and an electric sliding block, the electric sliding block is arranged on the guide rail, the electric sliding block is connected to the elastic sheet, and the electric sliding block is connected to the driving motor, so that the driving motor can drive the electric sliding block to slide on the guide rail, thereby driving the elastic sheet to move along the length direction of the guide rail.

[0053] The transmission members in the above embodiments are all linear transmission elastic sheets that translate along the length direction of the transmission members. It can be conceived that if the transmission member drives the elastic sheet to rotate, thereby driving the cleaning member to swing to achieve cleaning, the transmission member can be a rotating shaft, a gear transmission mechanism, or other structures, which will not be described here.

[0054] The following will be further described with the example of "the transmission member is a reciprocating screw 203, the reciprocating screw 203 is provided with two symmetrical and intersecting helical grooves along the length direction thereof, both ends of the two helical grooves are communicated, and the driving block 204 is slidably arranged in the helical grooves, and the driving block 204 is rotatably connected to the moving block 205".

[0055] Referring to Figure 1 , the cleaning mechanism 20 further includes two bearing plates 202, one end of the reciprocating screw 203 is connected to one of the bearing plates 202 through a bearing 214, and the other end of the reciprocating screw 203 is connected to the other bearing plate 202 through a bearing 214.

[0056] The cleaning mechanism 20 further includes a driving component, the driving component is connected to the reciprocating screw 203 to drive the reciprocating screw 203 to rotate.

[0057] In some embodiments, the driving component is a driving motor 210, which has a driving shaft connected to one end of the reciprocating screw 203. See Figure 1 When the driving motor 210 is turned on, the driving shaft of the driving motor 210 can drive the reciprocating screw 203 to rotate in one direction, and then the reciprocating screw 203 drives the driving block 204 and the moving block 205, and the linear transmission elastic sheet moves back and forth along the length direction of the reciprocating screw 203, thereby driving the cleaning member to rub back and forth on the surface to be cleaned, so as to clean the surface to be cleaned. The reciprocating screw 203 can avoid the driving motor 210 from frequently starting and stopping the forward and reverse rotation.

[0058] It can be understood that in other embodiments, the driving component can also be a cylinder, a motor, etc., which will not be described here.

[0059] In some embodiments, the cleaning mechanism 20 further comprises a guide member, which is arranged parallel to the transmission member, and the moving block 205 is movably arranged on the guide member, so that the guide member can guide the moving block 205 to move along the length direction of the guide member.

[0060] In some embodiments, the guide member is provided with at least two guide members to prevent the moving block 205 from rotating when moving on the guide member. See Figure 1 The guide member is provided with two guide members, and the moving block 205 is provided with two guide holes at intervals, and the two guide members are respectively arranged in the two guide holes, and the two ends of each guide member are respectively connected to the two bearing plates 202.

[0061] It can be understood that the number of guide members can be set according to actual needs, and no specific number is limited here.

[0062] In some embodiments, the guide member is a cylindrical guide rod 206. Of course, the guide member can also be an optical axis, a guide column or other guide members with guiding function, which will not be specifically limited here.

[0063] In some embodiments, the cleaning mechanism 20 further comprises a spray head, a conduit 212 and a water storage bottle 213. The spray head can be provided with one or more, and the spray head has a water spraying hole facing the cleaning member. The spray head is communicated with the water storage bottle 213 through the conduit 212, so that the water in the water storage bottle 213 can flow to the spray head through the conduit 212, and is sprayed to the cleaning member through the water spraying hole of the spray head, so as to wet the cleaning member for water cleaning.

[0064] In some embodiments, the spray head is an electromagnetic valve spray head 211, which is arranged on the elastic sheet. See Figure 1The electromagnetic valve nozzle 211 is arranged at one end of the elastic sheet close to the cleaning member. By opening the electromagnetic valve nozzle 211, the water spraying holes on the electromagnetic valve nozzle 211 can spray water towards the cleaning member, so as to wet the cleaning member and clean the surface to be cleaned with water.

[0065] It can be understood that the electromagnetic valve can also be arranged on the conduit 212 to open and close the passage between the water storage bottle 213 and the nozzle.

[0066] In some embodiments, the cleaning member is a scraper 208, and the outer periphery of the scraper 208 is sleeved with a rubber strip 209.

[0067] Of course, in other embodiments, the cleaning member can also be a cleaning roller, a cleaning cloth, or a brush or other cleaning member having a cleaning function.

[0068] In some embodiments, referring to Figure 2 The cleaning mechanism 20 further comprises a housing 201, and the transmission member is arranged in the housing 201. Specifically, the bearing plates 202 at both ends of the reciprocating screw 203 are fixed in the housing 201 by bolts. The cleaning member is arranged outside the housing 201, one end of the elastic sheet is arranged in the housing 201 to be connected with the transmission member, and the other end of the elastic sheet extends out of the housing 201 to be connected with the cleaning member.

[0069] Further, referring to Figure 2 The housing 201 is provided with a mounting strip 201a for mounting the housing 201.

[0070] The cleaning mechanism 20 further comprises a controller, and the driving motor 210 and the electromagnetic valve nozzle 211 are electrically connected with the controller. The opening and closing of the electromagnetic valve nozzle 211 and the opening and closing of the driving motor 210 can be remotely controlled by the controller.

[0071] The above scheme can also be equivalently replaced by: the driving motor 210 and the electromagnetic valve nozzle 211 are electrically connected to a remote control switch to realize remote control of the opening and closing of the electromagnetic valve nozzle 211, the opening and closing of the driving motor 210, and the rotation direction of the driving shaft.

[0072] In one specific embodiment, the cleaning mechanism 20 comprises a reciprocating screw 203, a driving block 204, a moving block 205, two guide rods 206, two bearing plates 202, a driving motor 210, an arc-shaped elastic steel sheet 207, a scraper 208, an electromagnetic valve nozzle 211, a conduit 212, a water storage bottle 213, a housing 201, and a controller.

[0073] Referring to Figure 1 and Figure 2The reciprocating screw 203 extends in horizontal direction, the two bearing plates 202 are arranged perpendicularly to the cross section of the reciprocating screw 203, and one end of the reciprocating screw 203 is connected to one of the bearing plates 202 through a bearing 214, and the other end is connected to the other bearing plate 202 through a bearing 214. The two bearing plates 202 are installed in the shell 201 through bolts, and the reciprocating screw 203, the driving block 204, the moving block 205 and the two guide rods 206 are located in the shell 201. One end of the arc-shaped elastic steel sheet 207 is located in the shell 201 to be connected to the moving block 205, and the other end of the arc-shaped elastic steel sheet 207 extends out of the shell 201 to be connected to the scraper 208 outside the shell 201. The outer surface of the shell 201 is provided with a mounting strip 201a for mounting the shell 201 to fix the cleaning mechanism 20.

[0074] One end of the reciprocating screw 203 penetrates through the bearing plate 202 and the shell 201 to be connected to the driving shaft of the driving motor 210, and the driving motor 210 is started to drive the reciprocating screw 203 to rotate. The driving motor 210 is electrically connected to the controller to enable remote control of the driving motor 210 by the controller.

[0075] The reciprocating screw 203 is provided with two symmetrical and intersecting spiral grooves along the length direction thereof, and the two ends of the two spiral grooves are communicated. The driving block 204 is slidably arranged in the spiral groove, so that the driving block 204 slides in the spiral groove when the reciprocating screw 203 rotates. During this process, sliding friction occurs between the reciprocating screw 203 and the driving block 204. Therefore, the driving block 204 is rotatably connected to the moving block 205 to reduce the sliding friction between the reciprocating screw 203 and the driving block 204.

[0076] The moving block 205 is provided with two guide holes arranged perpendicularly, and the two guide rods 206 are respectively arranged in the two guide holes, and the two guide rods 206 are parallel to the reciprocating screw 203. The two ends of each guide rod 206 are connected to the two bearing plates 202 respectively. The arrangement of the two guide rods 206 can guide the movement of the moving block 205, and the arrangement of the two guide rods 206 can prevent the moving block 205 from rotating when moving on the guide rod 206.

[0077] Referring to Figure 1The arc-shaped elastic steel sheet 207 extends in the vertical direction, one end of the arc-shaped elastic steel sheet 207 is connected with the side surface of the moving block 205, and two connection points are arranged at the end of the arc-shaped elastic steel sheet 207 away from the moving block 205 along the length direction of the arc-shaped elastic steel sheet 207, so as to be connected with the scraper 208, which can effectively prevent the scraper 208 from rotating when moving and cleaning. The scraper 208 is in a long strip shape, and the outer periphery of the scraper 208 is sleeved with a rubber strip 209. When the end of the arc-shaped elastic steel sheet 207 away from the moving block 205 is connected with the scraper 208, an elastic force is generated, which can be converted into a pressure force pressing the scraper 208, so that the scraper 208 and the rubber strip 209 are tightly attached to the surface to be cleaned.

[0078] The electromagnetic valve nozzle 211 is arranged at the end of the arc-shaped elastic steel sheet 207 close to the scraper 208, and the water spraying hole of the electromagnetic valve nozzle 211 faces the rubber strip 209 on the outer periphery of the scraper 208. The electromagnetic valve nozzle 211 is communicated with the water storage bottle 213 through the conduit 212, so that the water in the water storage bottle 213 can flow to the electromagnetic valve nozzle 211 through the conduit 212, and is sprayed to the rubber strip 209 through the water spraying hole on the electromagnetic valve nozzle 211, so as to wet the rubber strip 209 for water cleaning. The electromagnetic valve nozzle 211 is electrically connected with the controller, so that the opening and closing of the electromagnetic valve nozzle 211 can be remotely controlled through the controller.

[0079] The working principle of the cleaning mechanism 20 of the first aspect embodiment of the present application is as follows: when waterless cleaning is performed, the driving motor 210 is remotely turned on through the controller, the driving shaft of the driving motor 210 drives the reciprocating screw 203 to rotate, so that the reciprocating screw 203 can drive the driving block 204 and the moving block 205 to move the arc-shaped elastic steel sheet 207 back and forth along the length direction of the reciprocating screw 203 through linear transmission, further drive the scraper 208 to move back and forth, and the elastic force of the arc-shaped elastic steel sheet 207 makes the scraper 208 and the rubber strip 209 tightly attached to the surface to be cleaned, so that the scraper 208 and the rubber strip 209 can effectively clean the surface to be cleaned. When water cleaning is needed, the electromagnetic valve nozzle 211 is remotely turned on through the controller, so that the water spraying hole of the electromagnetic valve nozzle 211 can spray water to the rubber strip 209, so as to wet the rubber strip 209 for water cleaning.

[0080] The cleaning mechanism 20 of the first aspect of the present application comprises but is not limited to the following advantages: by setting the reciprocating screw 203, the indirect linear transmission of the scraper 208 with the rubber strip 209 around the scraper 208 is realized, so that the scraper 208 can move back and forth along the length direction of the reciprocating screw 203, thereby realizing the cleaning effect; and the setting of the reciprocating screw 203 can avoid the frequent start-stop of the driving motor 210; by setting the arc-shaped elastic steel sheet 207, pressure can be applied to the cleaning part, so that the scraper 208 can be tightly attached to the surface to be cleaned, thereby increasing the contact area between the scraper 208 and the surface to be cleaned, and when the scraper 208 moves, the friction between the scraper 208 and the surface to be cleaned is appropriately increased, thereby making the scraper 208 more easily remove dust and stains on the surface to be cleaned, enhancing the cleaning effect and improving the cleaning efficiency; the connecting point between the arc-shaped elastic steel sheet 207 and the scraper 208 is provided with at least two along the length direction of the scraper 208, which can effectively prevent the scraper 208 from rotating when moving and cleaning; the driving block 204 is rotatably connected to the moving block 205, which can reduce the sliding friction between the reciprocating screw 203 and the driving block 204; two guide rods 206 are provided to guide the movement of the moving block 205, which can prevent the moving block 205 from rotating when moving on the guide rod 206; by setting the electromagnetic valve spray head 211, the cleaning mechanism 20 has two cleaning modes of waterless cleaning and water cleaning; by remotely controlling the driving motor 210 and the electromagnetic valve spray head 211 through the controller, the opening and closing of the waterless cleaning mode and the water cleaning mode of the cleaning mechanism 20 can be realized, which provides great convenience for the use of the cleaning mechanism 20 and greatly enhances the practicability; by setting the shell 201, the dustproof and protective effects can be achieved.

[0081] Other configurations and operations of the cleaning mechanism 20 according to the first aspect of the present application are known to those skilled in the art, and will not be described in detail here.

[0082] Referring to Figures 2 to 5 , the second aspect of the present application provides a monitoring device, which comprises the cleaning mechanism 20 of the first aspect of the present application, and further comprises a monitoring device body 10, the cleaning mechanism 20 is installed on the monitoring device body 10, the monitoring device body 10 comprises a camera, and the cleaning part is used to clean the lens 101 of the camera.

[0083] Referring to Figure 2 , the shell 201 of the cleaning mechanism 20 is installed on the top of the camera. Specifically, the mounting strip 201a on the cleaning mechanism shell 201 is mounted on the camera by bolts. The water storage bottle 213 is also installed on the top of the camera and located at the rear of the shell.

[0084] It can be understood that the length of the helical groove on the reciprocating screw 207 should be equivalent to the length of the lens 101, and the length of the cleaning member should be equivalent to the width of the lens 101, so that the cleaning member can clean the lens 101 comprehensively, and prevent dead angles from occurring.

[0085] In some embodiments, referring to Figure 5 , the monitoring device body 10 is provided with a parking port 208a on one side of the lens 101, the extension direction of the parking port 208a is parallel to the length direction of the cleaning member, and the parking port 208a is located on the moving route of the cleaning member, so that the cleaning member can be placed in the parking port 208a. The bottom of the parking port 208a is parallel to the plane of the lens 101 surface, and the bottom of the parking port 208a is arranged behind the lens 101 surface along the normal direction of the lens 101 surface. Among them, the normal direction of the lens 101 surface is the C direction indicated by the arrow in the figure. That is, the bottom of the parking port 208a is lower than the lens 101 surface. Figure 5

[0086] When the cleaning member is not used, it is placed in the parking port 208a and does not block the field of view of the monitoring lens 101. And because the bottom of the parking port 208a is lower than the surface of the lens 101, when the cleaning member cleans the lens 101 after leaving the parking port 208a, it can be more compactly attached to the lens 101 surface, which is beneficial to enhance the cleaning effect.
