Description

Technical Field

[0001] The invention relates to the technical field of monitoring equipment installation accessories, and in particular to a positioning device with a heat dissipation structure for installing security monitoring equipment. Background Art

[0002] Security monitoring equipment is a device that uses a camera to monitor in real time. It can reflect the monitored object in real time, vividly and truthfully and record it through a video recorder, which not only greatly extends the observation distance of the human eye, but also expands the function of the human eye. It can replace manual long-term monitoring in harsh environments, allowing people to see everything that actually happens at the monitored site. The positioning device is an accessory for installing security monitoring equipment.

[0003] At present, the positioning device is generally in a box structure, such as the device disclosed in the authorization announcement number CN110430713A. The positioning device with a box structure can not only provide an installation platform for the security monitoring equipment, but also fully protect the security monitoring equipment. The security monitoring equipment needs to work continuously, which will inevitably generate a certain amount of heat. If the heat is not discharged in time, it will inevitably cause damage to the internal circuit device, etc., affecting the service life of the security monitoring equipment;

[0004] However, the box-shaped positioning device easily makes it difficult to discharge the heat generated by the security monitoring equipment, thereby generating heat accumulation. The conventional solution is to open multiple heat dissipation ports on the positioning device to increase the ventilation speed. However, the passive heat dissipation means of the heat dissipation ports are single, and the heat dissipation efficiency for the security monitoring equipment is low. In addition, multiple heat dissipation ports easily lead to the entry of foreign matter such as dust. The dust covers the surface of the security monitoring equipment, further affecting its heat dissipation efficiency. Therefore, we propose a positioning device with a heat dissipation structure for the installation of security monitoring equipment. Summary of the invention

[0036] Example

[0037] Please refer to Figures 1 to 8 As shown, the present invention provides a positioning device with a heat dissipation structure for installing security monitoring equipment, including a positioning box 1 for installing the security monitoring equipment, a heat dissipation component for cooling the security monitoring equipment is arranged inside the positioning box 1, and the heat dissipation component is composed of an air-cooled heat dissipation mechanism, a water-cooled heat dissipation mechanism and an extended heat dissipation mechanism. A dust-proof component for dust-proofing the heat dissipation component is arranged on the positioning box 1, and a dust removal component for cleaning the dust-proof component is arranged at the air inlet rear end of the dust-proof component. The air-cooled heat dissipation mechanism, the water-cooled heat dissipation mechanism and the extended heat dissipation mechanism in the heat dissipation component cooperate with each other to achieve efficient cooling of the security monitoring equipment, the dust-proof component prevents external impurities from adhering to the heat dissipation component to avoid affecting the heat exchange and cooling of the heat dissipation component, and the dust removal component cleans the dust-proof component to avoid the dust-proof component being blocked, thereby facilitating the long-term use of the dust-proof component;

[0038] Among them, the air-cooled heat dissipation mechanism includes a heat conducting plate 2, a pad 3 and a heat dissipation fan 4. Heat dissipation ports 5 are opened on both side surfaces of the positioning box 1. The heat conducting plate 2 is in contact with the side of the security monitoring equipment and is used to separate the left and right internal spaces of the positioning box 1. The pads 3 are distributed at intervals on the inner bottom of the positioning box 1, and the interval gaps of the pads 3 are connected to the left and right spaces separated by the heat conducting plate 2. The heat dissipation fan 4 is connected and installed in the top center of the positioning box 1; the air-cooled heat dissipation mechanism also includes an induced draft fan 18 and a drive motor 19. The heat conducting plate 2 is connected to a fixed cover shell 20 on one side facing the heat dissipation port 5. The drive motor 19 is installed inside the fixed cover shell 20 and its output shaft is connected and fixed to the induced draft fan 18. The induced draft fan 18 is located at the rear end of the air inlet of the heat dissipation fins 8; the heat conducting plate 2 is connected to the security monitoring equipment and is used to separate the left and right internal spaces of the positioning box 1. The pads 3 are distributed at intervals on the inner bottom of the positioning box 1, and the interval gaps of the pads 3 are connected to the left and right spaces separated by the heat conducting plate 2. The heat dissipation fan 4 is connected and installed in the top center of the positioning box 1; the air-cooled heat dissipation mechanism also includes an induced draft fan 18 and a drive motor 19. The heat conducting plate 2 is connected to a fixed cover shell 20 on one side facing the heat dissipation port 5. The drive motor 19 is installed inside the fixed cover shell 20 and its output shaft is connected and fixed to the induced draft fan 18. The induced draft fan 18 is located at the rear end of the air inlet of the heat dis The surface of the security monitoring equipment is attached to absorb the heat generated by the security monitoring equipment during operation. The heat conducting plate 2 expands the heat dissipation surface area of ​​the security monitoring equipment. The induced draft fan 18 starts to inhale the outside cold air from the heat dissipation port 5. The heat conducting plate 2 and the pad 3 cooperate with the inside of the positioning box 1 to form an air duct. The outside cold air flows along the interval gap of the pad 3 to the bottom of the security monitoring equipment. The heat dissipation fan 4 discharges the hot air that has completed the heat exchange with the security monitoring equipment inside the positioning box 1. The outside cold air rises under the guidance of the heat dissipation fan 4 to exchange heat with the security monitoring equipment to cool it down. The air contacts the security monitoring equipment from bottom to top, making the heat exchange coverage more comprehensive, and the hot air that has completed the heat exchange rises to accelerate the circulation of the air. At the same time, the accelerated flow of air is conducive to the heat dissipation and cooling of the heat conducting plate 2.

[0039] The water-cooled heat dissipation mechanism includes a lower water tank 6, an upper water tank 7, heat dissipation fins 8, a cooling water channel 9 and a water pump 10. The upper water tank 7 and the lower water tank 6 are respectively connected to the upper and lower surfaces of the positioning box 1. The heat dissipation fins 8 are vertically connected to the inner wall of the heat dissipation port 5. The cooling water channel 9 is respectively opened inside the heat conducting plate 2 and the heat dissipation fins 8, and the two ends are respectively connected to the upper water tank 7 and the lower water tank 6 to form a loop. The water pump 10 is installed in the lower water tank 6 and is connected to the cooling water channel 9 of the heat conducting plate 2; the lower water tank 6 has a coolant pre-stored inside, and the water pump 10 pumps the coolant along the cooling water channel 9 of the heat conducting plate 2 to the upper water tank 7. During the flow of the coolant along the cooling water channel 9, heat is exchanged with the heat conducting plate 2, thereby taking away the The heat of the heat conducting plate 2 is cooled, which is conducive to the heat conducting plate 2 to continuously exchange heat and cool down the security monitoring equipment. The coolant carrying heat flows back to the lower water tank 6 along the cooling water channel 9 of the heat dissipation fins 8. During the flow of the coolant along the cooling water channel 9, the coolant exchanges heat with the heat dissipation fins 8 to release heat. The coolant cools down and circulates along the cooling water channel 9 to achieve continuous heat dissipation and cooling of the security monitoring equipment. The induced draft fan 18 is started to inhale external cold air from the heat dissipation port 5. The cold air passing through the heat dissipation port 5 will contact the heat dissipation fins 8 to exchange heat, that is, the heat dissipation fins 8 are cooled, which is conducive to the heat dissipation fins 8 continuously cooling the coolant and ensuring the thermal conductivity of the coolant;

[0040] The expanded heat dissipation mechanism includes an overflow hole 11, a water guide plate 12, a water baffle plate 13 and a sealing plug 14. The overflow hole 11 is opened on the upper and lower inner walls of the heat dissipation port 5 and is respectively connected to the upper water tank 7 and the lower water tank 6.

The end of the water guide plate 12 is connected to the surface of the heat dissipation fin 8. The water baffle plate 13 is connected to the side of the port of the heat dissipation port 5. The sealing plug 14 is located inside the upper water tank 7 and connected to the overflow hole 11. The expansion heat dissipation mechanism also includes a positioning sleeve 15 and a screw 16, the positioning sleeve 15 is connected to the inner side wall of the upper water tank 7, the sealing plug 14 and the positioning sleeve 15 are slidably connected up and down, the screw 16 is rotatably arranged on the top surface of the sealing plug 14, the upper end thread of the screw 16 penetrates the top of the upper water tank 7, and the top end of the screw 16 is connected to a knob 17. When the positioning box 1 is installed, the sealing plug 14 is opened so that it no longer blocks the overflow hole 11, and the upper water tank 7 is opened. The cooling liquid flows along the overflow hole 11, and the water guide plate 12 is located below the overflow hole 11 to guide the cooling liquid to the surface of the heat sink 8. The cooling liquid flows along the surface of the heat sink fin 8 to the bottom of the heat sink 5 and finally flows back to the inside of the lower water tank 6 along the overflow hole 11. The water baffle 13 covers the port side of the heat sink 5, effectively preventing the cooling liquid from flowing out of the heat sink 5. The induced draft fan 18 is started and the outside air is sucked in through the heat sink 5. The air will contact the heat sink fin 8 to accelerate the evaporation of the cooling liquid on its surface. The evaporation of the liquid will absorb a large amount of heat, so that the air passing through the heat sink fin 8 is lower than the room temperature. The air entering the positioning box 1 is cold air, which is beneficial to the heat dissipation and cooling of the security monitoring equipment inside it, and improves the performance of the air-cooled heat dissipation mechanism. At the same time, the heat sink fin 8 absorbs heat by the evaporation of the liquid, which is beneficial to the cooling of the cooling liquid circulating inside it, ensuring the thermal conductivity of the cooling liquid, improving the performance of the water-cooled heat dissipation mechanism, and synergistically improving the heat dissipation and cooling of the security monitoring equipment by the heat dissipation component;

The dust removal component includes a cleaning brush 23, a shaft column 22 and a shaft sleeve 21. The shaft sleeve 21 is installed at the inner center of the heat dissipation port 5.

One end of the shaft column 22 is drivingly connected to the output shaft of the drive motor 19, and the other end of the shaft column 22 is located at the air inlet front end of the heat dissipation fin 8. The cleaning brush 23 The cleaning brush 23 is symmetrically connected to the front outer wall of the shaft column 22, and the inner side of the filter 25 is in contact with each other. The filter 25 prevents external impurities from entering the interior of the positioning box 1 through the heat dissipation port 5, and prevents external impurities from adhering to the heat dissipation fins 8, thereby affecting the thermal conductivity of the heat dissipation component. The driving motor 19 starts the induced draft fan 18 and drives the shaft column 22 to rotate relative to the shaft sleeve 21. The shaft column 22 drives the cleaning brush 23 to rotate relative to the surface of the filter 25 during the rotation process. The cleaning brush 23 cleans the filter 25 during the movement process, and prevents the filter 25 from being blocked, which is beneficial to the long-term use of the filter 25.
