Description

Technical Field

[0001] The present invention belongs to the technical field of communication equipment, and specifically relates to a monitoring camera for physical fitness assessment. Background Art

[0002] Physical fitness assessment is a process of testing and evaluating an individual's physical fitness level, usually including assessments of sports qualities such as strength, speed, and endurance. These assessment items aim to evaluate an individual's basic motor ability and the ability to adapt to future work or study needs. During the physical fitness assessment process, it is necessary to set up monitoring cameras at the assessment site. The monitoring cameras can record the assessment process in real time to ensure that the judgments and scores of the assessors are fair and accurate, and to avoid subjective biases or misjudgments.

[0003] The patent with the publication number CN111654610B discloses a self-cleaning and heat-dissipating monitoring camera, which includes a mounting base and a camera body. A fixing ring is provided on the mounting base, a rotating cylinder is fixedly installed inside the fixing ring, a light-transmitting plate is hermetically connected to the opening of the rotating cylinder, an installation cylinder is coaxially and rotatably installed inside the rotating cylinder, and the opening of the installation cylinder is hermetically and slidably connected to the side wall of the light-transmitting plate. Symmetrical partitions are connected to the outer wall of the installation cylinder, and each partition is hermetically and slidably connected to the inner wall of the rotating cylinder at the end far from the corresponding installation cylinder. This patent uses a driving agent to drive the rotating cylinder to reciprocate, so that multiple cooling chambers reciprocally dissipate heat from the camera body to ensure that the working temperature of the camera body is appropriate. At the same time, an annular airbag intermittently blows air to the light-transmitting plate to effectively blow off the dust adhering to it, thereby ensuring the use effect of the camera body.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: When applied to the physical fitness assessment site, if the assessment site is outdoors, due to strong outdoor winds, foreign objects such as plastic bags and cloth strips (such as plastic bags for holding drinks or cloth strips for marking and indicating paths) may be blown onto the camera and cover the camera's lens, resulting in the obstruction of the monitoring camera's line of sight and the inability to clearly capture and record the assessment process. And usually, in order to improve the monitoring effect, the monitoring camera is set at a relatively high position, and it is not easy for personnel to remove the foreign objects covering the camera.

Moreover, before the foreign object falls off the camera body, the volume of the foreign object can be reduced by making the foreign object into a roll, and then the foreign object is pushed off the camera body. Since the foreign object falling to the ground is in a rolled state and has a small volume, even if it moves on the ground at the assessment site under the action of wind, the impact on the assessors is negligible and can be ignored. Therefore, it is avoided that after the foreign object on the camera body is removed, due to the large volume of the foreign object and the influence of wind, it moves on the ground at the assessment site and interferes with the movement of the assessors, affecting the normal progress of the assessment.

[0017] 2. For a monitoring camera for physical fitness assessment of the present invention, by using the cleaning assembly, when dust adheres to the lens of the camera body, the brush plate can be driven to slide up and down along the first sliding rod, and the surface of the lens of the camera body can be cleaned by using the bristles on one side thereof, thereby realizing the cleaning work of the lens and further ensuring the clarity of the picture captured by the camera body.

Specific embodiments

[0021] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. 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.

[0022] Please refer to Figures 1-9 , the present invention provides a technical solution: a monitoring camera for physical fitness assessment, including a camera main body 1 and a mounting seat 2. The camera main body 1 is installed on the mounting seat 2, and a dragging and clamping mechanism for preventing foreign objects from covering the lens is provided on the camera main body 1; The dragging and clamping mechanism includes a limit block 27 fixedly connected to one side of the rear end of the camera main body 1. A rack bar 3 is slidably connected to one side of the limit block 27. The lower end surface of the rack bar 3 is attached to the upper end of the camera main body 1. A pressure bar 4 is rotatably provided on one side of the front end of the rack bar 3.

[0023] In this embodiment, as Figures 1-6 , Figure 8 , Figure 9As shown, on one side of the front end of the rack bar 3, a second motor 14 is fixedly connected. The output end of the second motor 14 is fixedly connected to one end of the pressure bar 4. On one side of the rear end of the camera body 1, a gear 26 is rotatably arranged. The gear 26 meshes with the tooth blocks on the rack bar 3. On one side of the rear end of the camera body 1, a sixth motor 25 is fixedly connected. The output end of the sixth motor 25 is fixedly connected to the gear 26.

[0024] A contraction mechanism for reducing the volume of the foreign object to be clamped is also provided on the camera body 1; The contraction mechanism includes a frame body 12 fixedly connected to one side of the upper end surface of the camera body 1. On both sides of the frame body 12, pressure rollers 13 are slidably connected through chutes. On one side of the camera body 1, a fixing plate 9 is fixedly connected. At both ends of one side of the fixing plate 9, third slide bars 16 are fixedly connected. The third slide bars 16 are slidably connected with a lifting block 18. On one side of the lower end of the lifting block 18, a suction roller 5 is rotatably arranged. On one side of the lifting block 18, two second slide bars 20 are slidably connected. One end of the second slide bars 20 is fixedly connected with a pushing ring 15. One side of the pushing ring 15 is in contact with the surface of the suction roller 5, and the pushing ring 15 can slide on the surface of the suction roller 5.

[0025] One end of the pressure roller 13 is fixedly connected with a spring 11. The end of the spring 11 away from the pressure roller 13 is fixedly connected to one side of the frame body 12.

[0026] One end of the lifting block 18 is threadedly connected with a second threaded rod 17. Both ends of the second threaded rod 17 are rotatably arranged on the fixing plate 9. On one side of the upper end of the fixing plate 9, a first motor 10 is fixedly connected. The output end of the first motor 10 is fixedly connected to one end of the second threaded rod 17.

[0027] One end of the second slide bar 20 is fixedly connected with a threaded block 30. One side of the threaded block 30 is threadedly connected with a third threaded rod 21. One end of the third threaded rod 21 is rotatably arranged on the lifting block 18. On one side of the lifting block 18, a fourth motor 22 is fixedly connected. The output end of the fourth motor 22 is fixedly connected to one end of the third threaded rod 21.

[0028] On one side of the lower end of the lifting block 18, a third motor 19 is fixedly connected. The output end of the third motor 19 is fixedly connected to one end of the suction roller 5.

[0029] On one side of the inner cavity of the suction roller 5, a vacuum pump 23 is fixedly connected. The air inlet end of the vacuum pump 23 is communicated with a long pipe 28. The long pipe 28 is fixedly connected to the inner cavity of the suction roller 5. A plurality of air inlets 31 are arranged on the long pipe 28. The air inlets 31 penetrate through the suction roller 5, and a suction cup 29 is arranged at one end of the air inlet 31 outside the suction roller 5.

[0030] Specifically, during the use of existing surveillance cameras, when applied to the physical fitness assessment site, if the assessment site is outdoors, due to strong outdoor winds, similar foreign objects such as plastic bags and cloth strips, like plastic bags for holding drinks or cloth strips used as markers or indicating paths, may be blown onto the camera and cover the camera lens, resulting in the obstruction of the surveillance camera's line of sight and making it impossible to clearly capture and record the assessment process. Moreover, usually, to improve the surveillance effect, the surveillance camera is set at a relatively high position, and it is not easy for personnel to remove the foreign objects covering the camera; Therefore, to solve the above problems, during the use of this embodiment, the camera body 1 is installed at a designated position in the assessment site through the mounting base 2, and the assessment site picture is recorded. When it is found that the lens of the camera body 1 is covered by foreign objects such as plastic bags and cloth strips, there must be some positions of the foreign objects above the camera body 1. Therefore, the rack bar 3 can be made to slide on the limit block 27 and move closer to the foreign object by driving the gear 26 to rotate by the motor six 25 until the rack bar 3 uses its end to push off the foreign object covering the lens of the camera body 1, thus realizing the removal of the foreign object covering the lens of the camera body 1 and avoiding the situation where the line of sight of the camera body 1 is blocked and thus unable to clearly capture and record the assessment process; Although the foreign matter at the camera body 1 can be removed by the above method, the foreign matter will eventually fall to the ground and move at the assessment site under the action of wind. When the volume of the foreign matter is large, it may interfere with the movement of the assessment personnel, thus affecting the normal progress of the assessment. Therefore, to avoid this problem, the end of the rack bar 3 is located at the rear end of the camera body 1. When the rack bar 3 approaches the foreign matter, it will pass under the bottom of the pressure roller 13, and the pressure roller 13 will rise due to the extrusion of the rack bar 3. Therefore, the pressure roller 13 will not interfere with the movement of the rack bar 3. After the pressure bar 4 passes through the pressure roller 13, the second motor 14 drives the pressure bar 4 to rotate, so that a 90-degree angle is formed between the pressure bar 4 and the rack bar 3. When the rack bar 3 touches the foreign matter covering the lens, the second motor 14 drives the pressure bar 4 to rotate, and the foreign matter is pressed against the rack bar 3 through the pressure bar 4. At this time, the foreign matter is clamped by the pressure bar 4 and the rack bar 3, and then the rack bar 3 is driven to reset. When the rack bar 3 resets, the foreign matter will pass through the frame 12. When the foreign matter passes through the frame 12, it will contract due to the small passage opening, and the width of the part of the foreign matter passing through the frame 12 is smaller than the length of the adsorption roller 5. Therefore, when the foreign matter is under the adsorption roller 5, the first motor 10 drives the second threaded rod 17 to rotate, so that the lifting block 18 descends, and the adsorption roller 5 presses the foreign matter against the upper surface of the camera body 1. At the same time, the suction cup 29 fits against the surface of the foreign matter, and then the air at the suction cup 29 is extracted by the vacuum pump 23, so that the suction cup 29 adsorbs the foreign matter. At this time, the pressure bar 4 can be driven to rotate to release the foreign matter, and then the third motor 19 drives the adsorption roller 5 to rotate. When the adsorption roller 5 rotates, it will wind up the foreign matter, and the foreign matter will continuously pass under the bottom of the pressure roller 13 until the foreign matter is wound around the adsorption roller 5 in a roll. At this time, the fourth motor 22 can be used to drive the third threaded rod 21 to rotate, so that the threaded block 30 and the second slide rod 20 move simultaneously. The second slide rod 20 moves on the lifting block 18, and the push ring 15 moves along the surface of the adsorption roller 5 to push the foreign matter sleeved on the adsorption roller 5 off. At this time, the foreign matter falling to the ground is in a rolled state, and its volume is reduced. Even if it moves on the ground at the assessment site under the action of wind, the impact on the assessment personnel is minimal and can be ignored, thus avoiding the situation that after the foreign matter on the camera body 1 is removed, due to the large volume of the foreign matter and the influence of wind, it moves on the ground at the assessment site and interferes with the movement of the assessment personnel, affecting the normal progress of the assessment.

[0031] In this embodiment, as Figure 7 shown, a cleaning assembly for cleaning the dust on the lens is further provided on the camera body 1; The cleaning assembly includes a first slide rod 8 fixedly connected to one side of the front end of the camera body 1. A brush plate 6 is slidably connected to the first slide rod 8, and the bristles of the brush plate 6 are in contact with the surface of the lens of the camera body 1.

[0032] One end of the brush plate 6 is threadedly connected to the first threaded rod 7. Both ends of the first threaded rod 7 are rotatably arranged on the camera body 1. One side of the front end of the camera body 1 is fixedly connected to the fifth motor 24. The output end of the fifth motor 24 is fixedly connected to one end of the first threaded rod 7.

[0033] Specifically, when dust adheres to the lens of the camera body 1, the fifth motor 24 can be driven to drive the first threaded rod 7 to rotate, so that the brush plate 6 slides up and down along the first slide rod 8, and the bristles on one side of the brush plate 6 can be used to clean the surface of the lens of the camera body 1, thereby realizing the cleaning work of the lens and further ensuring the clarity of the picture captured by the camera body 1.

[0034] Working principle: The camera body 1 is installed at a designated position at the assessment site through the mounting base 2, and the images of the assessment site are recorded. When it is found that the lens of the camera body 1 is covered by foreign objects such as plastic bags and cloth strips, there must be some positions of the foreign object above the camera body 1. Therefore, the rack bar 3 can be made to slide on the limit block 27 and approach the foreign object by driving the gear 26 to rotate through the sixth motor 25 until the foreign object covering the lens of the camera body 1 is pushed off by the end of the rack bar 3, thus realizing the removal of the foreign object covering the lens of the camera body 1 and avoiding the situation that the line of sight of the camera body 1 is blocked and the assessment process cannot be clearly captured and recorded;Although the foreign object at the camera body 1 can be removed by the above method, however, the foreign object will eventually fall to the ground and move at the assessment site under the action of wind. When the volume of the foreign object is large, it may interfere with the movement of the assessment personnel, thereby affecting the normal progress of the assessment. Therefore, to avoid this problem, the end of the rack bar 3 is located at the rear end of the camera body 1. When the rack bar 3 approaches the foreign object, it will pass under the bottom of the pressure roller 13, and the pressure roller 13 will rise due to the extrusion of the rack bar 3. Therefore, the pressure roller 13 will not interfere with the movement of the rack bar 3. After the pressure bar 4 passes the pressure roller 13, the second motor 14 drives the pressure bar 4 to rotate, so that a ninety-degree angle is formed between the pressure bar 4 and the rack bar 3. When the rack bar 3 touches the foreign object covering the lens, the second motor 14 drives the pressure bar 4 to rotate, and the foreign object is pressed against the rack bar 3 through the pressure bar 4. At this time, the foreign object is clamped by the pressure bar 4 and the rack bar 3, and then the rack bar 3 is driven to reset. When the rack bar 3 resets, the foreign object will pass through the frame 12. When the foreign object passes through the frame 12, it will contract due to the small passage opening, and the width of the part of the foreign object passing through the frame 12 is smaller than the length of the adsorption roller 5. Therefore, when the foreign object is under the adsorption roller 5, the first motor 10 drives the second threaded rod 17 to rotate, so that the lifting block 18 descends, and the adsorption roller 5 presses the foreign object against the upper surface of the camera body 1. At the same time, the suction cup 29 fits against the surface of the foreign object, and then the air at the suction cup 29 is extracted by the vacuum pump 23, so that the suction cup 29 adsorbs the foreign object. At this time, the pressure bar 4 can be driven to rotate to release the foreign object, and then the third motor 19 drives the adsorption roller 5 to rotate. When the adsorption roller 5 rotates, it will wind up the foreign object, and the foreign object will continuously pass under the bottom of the pressure roller 13 until the foreign object is wound around the adsorption roller 5 in a roll. At this time, the fourth motor 22 can be used to drive the third threaded rod 21 to rotate, so that the threaded block 30 and the second slide rod 20 move simultaneously. The second slide rod 20 moves on the lifting block 18, and the pushing ring 15 moves along the surface of the adsorption roller 5 to push the foreign object sleeved on the adsorption roller 5 to fall off. At this time, the foreign object falling to the ground is in a rolled state, and its volume is reduced. Even if it moves on the ground at the assessment site under the action of wind, the impact on the assessment personnel is minimal and can be ignored, thus avoiding the situation that after the foreign object on the camera body 1 is removed, due to the large volume of the foreign object and the influence of wind, it moves on the ground at the assessment site and interferes with the movement of the assessment personnel, affecting the normal progress of the assessment. When there is dust attached to the lens of the camera body 1, the fifth motor 24 can be used to drive the first threaded rod 7 to rotate, so that the brush plate 6 slides up and down along the first slide rod 8, and the bristles on one side of it can be used to clean the surface of the lens of the camera body 1, thereby realizing the cleaning work of the lens and further ensuring the clarity of the picture captured by the camera body 1.;
