Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1, referring to Figures 1-11 , the anti-suicide intelligent video analysis and early warning device for psychiatric wards includes a substrate 1. A support member 8 is fixedly connected to the outer side wall of the substrate 1. An electric rotating member 9 is installed on the outer side wall of the support member 8. A camera body 10 is rotatably connected to the electric rotating member 9. A camera lens 11 is provided on the camera body 10. A signal transmission module is provided inside the camera body 10. A guide rail 2 is fixedly connected to the outer side wall of the substrate 1. A starting motor 3 is fixedly connected to the outer side wall of the upper end of the guide rail 2. The output end of the starting motor 3 is provided with a threaded rod 4. The threaded rod 4 rotates through to the inside of the guide rail 2. A support arm 5 is threadedly sleeved on the threaded rod 4. A camera cleaning mechanism is provided on the support arm 5;

[0033] The camera cleaning mechanism includes a mounting plate 22 fixedly connected to the end of the support arm 5. A driving motor 23 is fixedly connected to the outer side wall of the mounting plate 22. The output end of the driving motor 23 is provided with a telescopic rod 24. The end of the telescopic rod 24 is provided with a horizontal box 28. One end of the telescopic rod 24 close to the horizontal box 28 is hollow. A plurality of cleaning brushes 29 are fixedly connected to the bottom of the horizontal box 28. A plurality of drip tubes 30 are communicated with the bottom of the horizontal box 28. The bottoms of the plurality of drip tubes 30 are sealed. Scouring holes 43 are formed on both sides of the plurality of drip tubes 30.

[0034] An upper cylinder 25 and a lower cylinder 26 are respectively arranged on the outer side wall of the telescopic rod 24. A plurality of side boxes 34 are fixedly connected to the outer side wall of the lower cylinder 26. A spray pipe 35 is arranged inside each of the plurality of side boxes 34. The end of the spray pipe 35 is communicated with the inside of the lower cylinder 26.

[0035] Limit rods 36 are fixedly connected to both sides of the side box 34. A sliding plate 38 is slidably connected to the outer side walls of the two limit rods 36. Pressure springs 37 are sleeved on the outer side walls of the two limit rods 36. The middle part of the sliding plate 38 is slidably connected to the outer wall of the spray pipe 35. A fixing rod 39 is fixedly connected to the outer side wall of the sliding plate 38. A blocking plug 40 is arranged on the fixing rod 39. The blocking plug 40 blocks the end of the spray pipe 35. A mixing mechanism is arranged on the side box 34.

[0036] In this embodiment, when in use, the electric rotating member 9 can be used to control the camera body 10 to rotate left and right and turn up and down, so as to flexibly monitor the patients in the ward, and the monitoring picture is transmitted back to the anti-suicide intelligent video analysis and early warning device through the signal transmission module, and the early warning device performs suicide tendency analysis (this is the prior art and will not be elaborated too much).

[0037] When dust adheres to the surface of the camera lens 11 on the camera body 10, affecting the monitoring clarity of the camera lens 11, the operator can first tilt the camera body 10 upward by a specified angle through the electric rotating member 9, and then turn on the starting motor 3 to drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, it will cause the support arm 5 to drive mechanisms such as the mounting plate 22 to move downward. When the mounting plate 22 drives the horizontal box 28 to move to the side of the camera lens 11, the operator can turn on the driving motor 23, which drives the horizontal box 28 to rotate through the telescopic rod 24. When the horizontal box 28 rotates, it will scrape and clean the surface of the camera lens 11 through the cleaning brush 29 at its bottom. When the telescopic rod 24 rotates, it will also drive the lower cylinder 26 to rotate synchronously. When the lower cylinder 26 rotates, it will drive a plurality of side boxes 34 on its surface to rotate synchronously. When the side box 34 rotates, under the action of the centrifugal force generated by the rotation, the slide plate 38 will drive the blocking plug 40 to move toward the direction close to the conduit 33 against the elastic force of the compression spring 37. When the blocking plug 40 moves toward the direction close to the conduit 33, it will separate from the end of the nozzle 35 and no longer block the end of the nozzle 35. At this time, the cleaning liquid stored in the lower cylinder 26 will be sprinkled into the side box 34 through the nozzle 35 when the lower cylinder 26 rotates. The cleaning liquid entering the side box 34 will be transported through the conduit 33 into the telescopic rod 24, and finally flow into the horizontal box 28 through the bottom hole 31, and drip onto the surface of the camera lens 11 through the flushing holes 43 on the plurality of drip tubes 30, cooperating with the scraping of the cleaning brush 29 to clean the surface of the camera lens 11, so as to ensure the imaging clarity of the camera body 10.

[0038] Embodiment 2, referring to Figures 1-11 , the mixing mechanism includes a vertical box 41 arranged on the side box 34. The inside of the vertical box 41 is communicated with a mixing pipe 32, and one end of the mixing pipe 32 away from the vertical box 41 is communicated with the inside of the upper cylinder 25.

[0039] A baffle 42 is slidably connected through the inside of the vertical box 41. A circulation hole 21 is opened on the baffle 42, and the end of the baffle 42 is fixedly connected to the blocking plug 40.

[0040] The bottom of the side box 34 is communicated with a conduit 33. One end of the conduit 33 away from the side box 34 is communicated with the inside of the telescopic rod 24. A bottom hole 31 is opened at the bottom of the telescopic rod 24, and the bottom hole 31 penetrates into the inside of the horizontal box 28.

[0041] The inside of both the upper cylinder 25 and the lower cylinder 26 is communicated with an infusion tube 27, and a one-way valve is arranged inside the infusion tube 27.

[0042] A storage box 6 is fixedly connected to the outer side wall of the guide rail 2. The interior of the storage box 6 is respectively provided with a left chamber 19 and a right chamber 20. Liquid filling ports 7 are respectively arranged inside the left chamber 19 and the right chamber 20. Liquid filling pipes 16 are slidably connected inside the left chamber 19 and the right chamber 20. A pressing spring 17 is sleeved on the outer side wall of the liquid filling pipe 16. A plurality of through holes 18 are arranged on the liquid filling pipe 16. One end of the liquid filling pipe 16 close to the through holes 18 is sealed. The liquid filling pipe 16 is located directly above the infusion pipe 27.

[0043] A diversion box 12 is fixedly connected to the outer side wall of the camera body 10. A hose 13 is communicated and arranged at the bottom of the diversion box 12. A dirt storage box 14 is fixedly connected to the outer side wall of the substrate 1. A liquid discharge port 15 is communicated and arranged at the bottom of the dirt storage box 14. One end of the hose 13 far away from the diversion box 12 is communicated into the interior of the dirt storage box 14.

[0044] In this embodiment, when the surface of the camera lens 11 on the camera body 10 is contaminated with patient secretions or sweat and it is difficult to clean with ordinary cleaning agents, at this time, the operator can increase the power of the driving motor 23, so that it drives the horizontal box 28 to rotate at a high speed through the telescopic rod 24. When the telescopic rod 24 drives the horizontal box 28 to rotate at a high speed, referring to the above principle, it will also drive the lower cylinder 26 and the upper cylinder 25 to rotate synchronously. When the lower cylinder 26 and the upper cylinder 25 rotate at a high speed along with the telescopic rod 24, at this time, under the action of a large centrifugal force, the blocking plug 40 driven by the sliding plate 38 will move a large distance towards the direction close to the conduit 33. At this time, not only will the blocking plug 40 separate from the end of the spray pipe 35, but also the baffle 42 will move a large distance towards the direction close to the conduit 33 together with the blocking plug 40, so that the circulation hole 21 originally located outside the baffle 42 enters the vertical box 41. When the circulation hole 21 enters the vertical box 41, at this time, the degradation cleaning liquid transported to the interior of the vertical box 41 by the upper cylinder 25 through the mixing pipe 32 will drip into the interior of the side box 34 through the circulation hole 21, mix with the normal cleaning liquid sprayed by the spray pipe 35, and finally flow into the interior of the horizontal box 28 through the conduit 33, and drip onto the surface of the camera lens 11 through the flushing holes 43 on the drip pipe 30, and cooperate with the scraping of the cleaning brush 29 to clean the stubborn stains on the surface of the camera lens 11, so as to ensure the use effect of the entire warning device.

[0045] It should be noted that after the surface of the camera lens 11 is cleaned, the operator can first retract the telescopic rod 24, and then turn on the starting motor 3 to drive the threaded rod 4 to reverse. When the threaded rod 4 reverses, the support arm 5 will drive the mounting plate 22 to move upward. When the mounting plate 22 moves upward, the liquid adding pipes 16 in the left chamber 19 and the right chamber 20 will first be inserted into the corresponding infusion pipes 27. After the two liquid adding pipes 16 are inserted into the two infusion pipes 27, under the push of mechanisms such as the mounting plate 22, the two liquid adding pipes 16 will move into the left chamber 19 and the right chamber 20 respectively, so that the through holes 18 on the two liquid adding pipes 16 enter the left chamber 19 and the right chamber 20 respectively. At this time, the normal cleaning liquid and the degradation cleaning liquid stored in the left chamber 19 and the right chamber 20 will enter the corresponding liquid adding pipes 16 through the corresponding through holes 18, and then be transported into the upper cylinder 25 and the lower cylinder 26 through the infusion pipes 27 corresponding to the two liquid adding pipes 16 to supplement the degradation cleaning liquid and the normal cleaning liquid inside the upper cylinder 25 and the lower cylinder 26, which is convenient for use. And one-way valves are provided inside both of the two infusion pipes 27, which only allow liquid to enter and not to flow out. Therefore, when the upper cylinder 25 and the lower cylinder 26 rotate, they will not spill liquid outward. At the same time, the driving motor 23 is a stepping motor with an internal positioning encoder. Each time the telescopic rod 24 stops rotating after being driven to rotate, the telescopic rod 24 can stay in a fixed position, that is, the infusion pipe 27 is in an upward state (refer to Figure 9 ).

[0046] It should be noted that the cleaning liquid dripped by the drip irrigation pipe 30 onto the surface of the camera lens 11 will flow into the diversion box 12 after cleaning the surface of the camera lens 11, and finally flow into the dirt storage box 14 through the delivery of the hose 13 at the bottom of the diversion box 12. The hose 13 is made of relatively soft rubber, and when the camera body 10 rotates and adjusts, the hose 13 will not restrict the camera body 10.

[0047] It should be noted that multiple drip irrigation pipes 30 are respectively arranged crosswise between multiple cleaning brushes 29. Before the cleaning liquid transported by the flushing holes 43 drips onto the surface of the camera lens 11 through the flushing holes 43, the cleaning liquid transported by the flushing holes 43 will first drip onto the surface of the cleaning brush 29, and finally flow down the cleaning brush 29 to the surface of the camera lens 11. By preferentially flushing the cleaning brush 29, it is possible to prevent stains from remaining on the surface of the cleaning brush 29.

[0048] It should be noted that when cleaning stubborn stains on the surface of the camera lens 11, mixing ordinary cleaning agent with degradable cleaning agent can allow solvents such as ethanol in the normal cleaning liquid to penetrate and soften the stains, destroying their adhesion to the lens surface. The enzyme components in the degradable cleaning liquid can deeply decompose the softened organic pollutants to prevent residues. This synergistic effect can increase the cleaning efficiency by more than 40%, especially suitable for the rapid cleaning of mixed stains such as sweat, dust, and secretions. At the same time, the ordinary cleaning agent contains more ethanol, which can volatilize quickly whether it is used alone or in combination with the degradable cleaning agent to clean the camera lens 11, and there is no need to rinse with clean water anymore.

[0049] It should be noted that when the telescopic rod 24 drives the lower cylinder 26 to rotate at a normal speed, the moving distance of the blocking plug 40 towards the direction of the conduit 33 is relatively small at this time, which is not enough to drive the flow hole 21 into the vertical box 41. Correspondingly, when the horizontal box 28 rotates at a normal speed to clean the dust on the surface of the camera lens 11, the drip tube 30 will only drip the normal cleaning liquid onto the surface of the camera lens 11, and will not drip the mixed cleaning liquid. Since the degradable cleaning liquid is more expensive than the normal cleaning liquid, only using the normal cleaning liquid to clean the dust can ensure the cleaning effect and help save the cleaning cost at the same time.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
