Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and in particular to a surveillance camera with limited-distance warning and identification. Background Art

[0002] A surveillance camera is an instrument used to photograph and monitor the observation area required by the user. Most of them have a recording function. Surveillance cameras are commonly installed outdoors for users to conduct security management of the observation area to achieve the purpose of security control. For example, at the entrance and exit of an outdoor parking lot, surveillance cameras can scan and identify the license plates of vehicles entering and leaving the parking lot within a certain distance to conduct entry and exit security control of the target vehicles.

[0003] For example, CN117629154A discloses a multifunctional surveillance camera device and a method of using the same. The camera device can remotely control 360-degree horizontal rotation and vertical rotation by modifying the camera structure and setting a laser rangefinder or laser radar scanner on the top of the camera device. At the same time, the size of the structure can be detected by using prism-free laser ranging and laser scanning according to the needs of the site. The existing surveillance camera measures the distance between the photographed identification target and itself through a laser rangefinder and other equipment, thereby controlling the photographed identification target to maintain a suitable scanning distance with the camera, so as to maintain a good clear recognition of the photographed identification target during photographing and identification. However, the existing surveillance cameras used outdoors generally have an inclined front shield on the outer wall of the shell at the top of the lens. In heavy rain, the front shield can well block the rain falling from above to prevent it from adhering to the lens and affecting the shooting clarity. However, since the side panels on both sides of the front shield are inclined, raindrops will still be scraped obliquely from the side to the lens surface under the action of wind, thereby affecting the shooting of the surveillance camera.

[0004] Therefore, a surveillance camera with limited distance warning recognition is introduced. Summary of the invention

[0032] In order to solve the problem that the front shield of existing surveillance cameras has limited ability to block raindrops blown diagonally from the sides of the lens, and strong winds can easily blow raindrops diagonally onto the surface of the lens and affect the clarity of the shot, please refer to Figure 1-Figure 6 , provide the following preferred technical solutions:

[0033] A drainage chamber 12 is provided inside one end of the outer shell 1, and the top of the drainage chamber 12 is connected to the bottom of one end of the rain collecting trough 11.

An L-shaped push rod 16 is threadedly sleeved on the outer wall of the adjusting rod 15, and the end of the L-shaped push rod 16 extends through and into the storage groove 4;

[0034] A mounting groove 51 is provided on the outer wall of the auxiliary baffle plate 5 on the side close to the end of the storage groove 4, and a sliding cavity 52 is provided inside the auxiliary baffle plate 5 on the inner side of the mounting groove 51, a deflection rod 53 is movably connected between the inner walls at one end of the mounting groove 51, and a winding drum 54 is provided between the inner walls at both ends of the mounting groove 51 on the inner side of the deflection rod 53, a waterproof cloth 55 is rolled up in the winding drum 54, and the winding drum 54 has the function of heat preservation and heat insulation, and is used to protect the waterproof cloth 55 to prevent aging damage, and a rope edge 56 is fixedly connected to the end of the waterproof cloth 55, and the two ends of the rope edge 56 are respectively fixedly connected to the inner wall at the bottom of the storage groove 4 and the side wall of the movable end of the deflection rod 53, a counterweight slider 57 is movably engaged in the sliding cavity 52, and the end of the counterweight slider 57 is fixedly connected to an adjusting rope 58, and the other end of the adjusting rope 58 passes through the end of the mounting groove 51 and is fixedly connected to the outer wall at the end of the deflection rod 53.

[0035] The worm adjustment member 14 includes a first worm wheel 141 fixedly sleeved on the outer wall of the driving rod 13, a worm 142 is movably arranged between the inner walls on both sides of the inner cavity of the outer shell body 1 above the first worm wheel 141, the meshing portion on the outer wall at the middle part of the worm 142 is meshed with the top end of the first worm wheel 141, and the top ends of the meshing portions at both ends of the worm 142 are meshed and connected with second worm wheels 143, and the second worm wheels 143 at the top ends of the worm 142 are fixedly sleeved on the outer wall of the adjusting rod 15 respectively.

[0036] The winding drum 54 includes a protective tube seat 541 fixedly connected to the inner walls at both ends of the mounting groove 51 and a winding roller 542 movably connected to the inner walls at both ends of the protective tube seat 541, an axle rod is fixedly connected to the outer walls at both ends of the winding roller 542, the ends of the axle rod are movably connected to the inner walls at both ends of the protective tube seat 541, and a clockwork spring 543 is fixedly wound on the outer wall of the axle rod, the outer end of the clockwork spring 543 is fixedly connected to the inner wall of the protective tube seat 541, and the waterproof cloth 55 is wound on the outer wall of the winding roller 542, and the end of the waterproof cloth 55 passes through the through hole at the bottom of the protective tube seat 541.

[0037] When the clockwork spring 543 maintains a normal relaxed state, the auxiliary baffle 5 is vertically stored in the storage groove 4. At this time, the deflection rod 53 is folded in the installation groove 51, the waterproof cloth 55 is completely rolled up on the outer wall of the winding roller 542, and the counterweight slider 57 is located on the side of the sliding cavity 52 close to the fixed end of the deflection rod 53.

[0038] Specifically, when it rains, rainwater enters the rainwater collecting trough 11, is filtered by the filter screen 111, and then is collected into the drainage chamber 12 inside the outer shell 1 along the inclined bottom plate of the rainwater collecting trough 11. When the rainwater flows vertically downward in the drainage chamber 12, it drives the turbine 122 to rotate. The turbine 122 uses the positioning shaft 121 to cooperate with the bevel gear set 123 to drive the driving rod 13 to rotate. The driving rod 13 drives the first worm gear 141 to rotate. The first worm gear 141 uses the worm 142 to cooperate with the second worm gears 143 at both ends to respectively drive the adjusting rods 15 on both sides of the inner cavity of the outer shell 1 to rotate. When the adjusting rod 15 rotates, the screw drive L The L-shaped push rod 16 moves horizontally, and the end of the cross bar of the L-shaped push rod 16 pushes the auxiliary baffle 5 toward the outside of the port of the storage slot 4 when the cross bar end of the L-shaped push rod 16 translates, so that the lower end of the auxiliary baffle 5 deflects upward until it is horizontal, and the end of the cross bar of the L-shaped push rod 16 fits the bottom of the auxiliary baffle 5 to support it. When the auxiliary baffles 5 on both sides of the camera 2 deflect upward to the horizontal, the movable rod of the deflection rod 53 in the mounting groove 51 at the bottom of the auxiliary baffle 5 deflects downward under the action of gravity, thereby deflecting away from the auxiliary baffle 5. When the movable end of the deflection rod 53 deflects downward, the adjusting rope 58 is used to pull the counterweight slider 57 in the sliding cavity 52 toward the fixed end of the auxiliary baffle 5 The auxiliary baffle 5 is slid to one side, and after the auxiliary baffle 5 is deflected to the horizontal, the movable end of the deflection rod 53 is deflected downward to be perpendicular to the auxiliary baffle 5. The deflection rod 53 is deflected vertically and the waterproof cloth 55 in the winding drum 54 is pulled, and finally the rope edge 56 is used to tighten the waterproof cloth 55 and vertically fit the inner wall of the side plates at both ends of the rain shield 3. By collecting rainwater and adjusting and controlling the auxiliary baffle 5 based on gravity, the auxiliary baffle 5 automatically opens the waterproof cloth 55 and suspends it on both sides of the camera 2 when it rains, effectively avoiding the problem that strong wind blows raindrops obliquely onto the lens surface of the camera 2, ensuring the clear recognition of the camera 2 at a fixed distance. Clarity, convenience and practicality. After the rain stops, the adjusting rod 15 rotates in the opposite direction to drive the L-shaped push rod 16 cross bar to move toward the inner cavity of the outer shell 1, and the end of the auxiliary baffle 5 deflects downward. At this time, the counterweight slider 57 slides toward the inclined lower end of the auxiliary baffle 5. When the counterweight slider 57 moves, it drives the active end of the deflection rod 53 to deflect upward and fold into the mounting groove 51 on the auxiliary baffle 5. In this process, the tension state of the rope edge 56 at the bottom of the waterproof cloth 55 becomes loose. When the active end of the deflection rod 53 deflects upward, the winding roller 542 rotates in the opposite direction under the push of the contracted spring spring 543 to automatically wind up the waterproof cloth 55.

[0039] Furthermore, it is convenient to manage the waterproof cloth 55 when there is no rain, such as Figure 2-Figure 7 As shown, this implementation provides the following preferred technical solutions:

[0040] The adjusting rod 15 includes a first straight rod 151 movably arranged on the inner wall of the inner cavity of the outer shell 1, a second worm gear 143 is fixedly sleeved on the outer wall of the first straight rod 151, a positioning cylinder 152 is movably sleeved on the end of the first straight rod 151, inner grooves 153 are evenly spaced in a ring shape on the outer wall of the first straight rod 151 in the positioning cylinder 152, an elastic component 154 is fixedly connected to the inner wall of the inner groove 153, a wedge head 155 is fixedly connected to the end of the elastic component 154, and limiting grooves are respectively provided on the inner wall of the positioning cylinder 152 corresponding to the wedge head 155, an adjusting screw 156 is fixedly connected to the outer wall of the positioning cylinder 152 away from the opening end, the bottom end of the vertical rod of the L-shaped push rod 16 is movably sleeved on the outer wall of the adjusting screw 156, and the end of the horizontal rod of the L-shaped push rod 16 extends through the storage groove 4 and is arranged in contact with the auxiliary baffle 5.

[0041] A lifting rope 157 is wound around the outer wall of the positioning cylinder 152, and a U-shaped rod 19 is fixedly connected to the top of the inner cavity of the outer shell 1 above the positioning cylinder 152. The lifting rope 157 is passed through and overlapped on the top of the cross bar of the U-shaped rod 19, and a counterweight lifting block 158 is fixedly connected to the bottom of the end of the lifting rope 157.

[0042] Specifically, when the turbine 122 uses the positioning shaft 121 to cooperate with the bevel gear set 123 to drive the driving rod 13 to rotate, the driving rod 13 uses the first worm gear 141 and the worm 142 to cooperate with the second worm gear 143 to respectively drive the first straight rods 151 on both sides of the inner cavity of the outer shell 1 to rotate, and the first straight rod 151 drives the L-shaped push rod 16 to translate and push the auxiliary baffle 5 to deflect through the positioning cylinder 152 and the adjusting screw 156. When the positioning cylinder 152 rotates, the lifting rope 157 is rolled up and the counterweight is suspended based on the U-shaped rod 19 cross bar. The block 158 is lifted, and when the vertical rod of the L-shaped push rod 16 is attached to the inner cavity side wall of the outer shell 1 and cannot move, the auxiliary baffle 5 is deflected to the horizontal, and the counterweight block 158 is lifted to the bottom of the U-shaped rod 19. At this time, when the turbine 122 is impacted by the water flow and drives the first straight rod 151 to continue to rotate, due to the limitation of the L-shaped push rod 16, the first straight rod 151 pushes the wedge head 155 in the sliding groove limit groove to squeeze the elastic component 154 when the positioning cylinder 152 rotates, and pushes the wedge head 155 again when it rotates to the next limit groove. The first straight rod 151 is engaged with the limiting groove 5, so that the first straight rod 151 can smoothly rotate in the positioning tube 152, so as to avoid the L-shaped push rod 16 being unable to move and causing water flow to impact the turbine 122 and cause damage. At the same time, the height of the counterweight block 158 is kept from decreasing by the friction between the first straight rod 151 and the positioning tube 152. After the rain stops, the turbine 122 stops rotating, the first straight rod 151 is stationary in the positioning tube 152, and the wedge heads 155 are respectively engaged with the limiting grooves on the inner wall of the positioning tube 152. The counterweight block 158 is held in the position by gravity. The lifting rope 157 is dragged downward to drive the positioning cylinder 152 and the adjusting screw 156 to rotate in the opposite direction, so that the cross bar of the L-shaped push rod 16 returns to the inner cavity of the outer shell 1, so that the auxiliary baffle 5 is automatically deflected and folded downward under the action of gravity. When the end of the auxiliary baffle 5 is deflected and close to the storage groove 4, the tension state of the rope edge 56 at the lower end of the waterproof cloth 55 becomes loose, and the winding roller 542 inside the winding drum 54 automatically winds up the waterproof cloth 55 under the action of the clockwork spring 543 to prevent it from affecting the deflection and folding of the auxiliary baffle 5, which is easy to use.

[0043] like Figure 2 , Figure 8 and Fig. 9 As shown, in order to better ensure the shooting clarity of camera 2, this example provides the following technical solutions:

[0044] The camera 2 includes a mounting base 21 fixedly connected to the outer wall of the front end of the outer shell 1, a positioning cavity is opened on the outer wall of the end of the mounting base 21, a lens body 22 is fixedly connected to the inner wall of the positioning cavity, a protective lens is fixedly connected between the inner walls of the positioning cavity port outside the lens body 22, a confluence cavity 23 is arranged inside one side of the fixed end of the mounting base 21, and air outlet channels are evenly spaced inside the mounting base 21 outside the confluence cavity 23, the air inlet end of the confluence cavity 23 is connected to the inner cavity of the outer shell 1, and an annular groove is opened on the outer wall of the mounting base 21 corresponding to the air outlet channel, and an auxiliary part 6 is movably engaged in the annular groove.

[0045] The auxiliary part 6 includes an annular tube 61 that is movably engaged in the annular groove, a gear ring 62 is fixedly connected to the edge of one side of the inner wall of the middle hole of the annular tube 61, a circular cavity is provided in the mounting seat 21 adjacent to the gear ring 62, the end of the driving rod 13 movably extends through the circular cavity, the end of the driving rod 13 in the circular cavity is fixedly connected to an auxiliary gear 131, the top of the auxiliary gear 131 is meshed with the gear ring 62, and the side wall of the annular tube 61 is evenly spaced and fixedly connected with interconnected jet pipes 63, and the jet pipes 63 are evenly spaced and parallel and are distributed around the outside of the mounting seat 21.

[0046] An annular opening is provided on the inner wall of the middle hole of the annular tube 61 on one side of the gear ring 62, and the annular opening ring is sleeved on the outside of the air outlet channel port, and a branch pipe 64 is fixedly connected to the side wall at the end port of the jet pipe 63, and the end of the branch pipe 64 is inclined and close to the positioning cavity port on the mounting seat 21.

[0047] Specifically, when rainwater flows vertically downward in the drainage cavity 12 and drives the turbine 122 to rotate, the turbine 122 uses the positioning shaft 121 to cooperate with the bevel gear set 123 to drive the driving rod 13 to rotate, and the driving rod 13 drives the annular tube 61 in the annular groove on the outer wall of the mounting seat 21 to rotate based on the auxiliary gear 131 meshing gear ring 62. When the annular tube 61 rotates, it drives the jet pipe 63 and the branch pipe 64 to rotate around the protective lens at the positioning cavity port outside the lens body 22. When the micro fan 18 inside the inner cavity of the outer shell 1 cools the main unit 17, the airflow enters the housing 1. The air flows into the confluence cavity 23, and enters the annular tube 61 through the air outlet channel and the annular opening on the inner wall of the middle hole of the annular tube 61, and is finally ejected from the end ports of the jet pipe 63 and the branch pipe 64. After the airflow is ejected, two wind curtains are formed by rotation on the outside of the protective lens. The straight-cylindrical wind curtain surrounds the outside of the conical wind curtain ejected from the inclined branch pipe 64, thereby continuously blowing away the cold and humid airflow and raindrops blowing toward the protective lens, avoiding them from being mounted on the surface of the protective lens to form water mist and affecting the shooting clarity of the camera 2, further ensuring the clear warning recognition effect of the camera 2.
