Description

Technical Field

[0001] This utility model belongs to the field of cloud broadcasting technology, and in particular relates to a rainproof and dustproof cloud broadcasting power distribution box. Background Technology

[0002] Cloud broadcasting refers to a broadcasting system deployed and implemented using a cloud computing model. As an efficient one-to-many communication method, broadcasting systems are widely used in places such as stations, airports, factories, schools, and hotels. While different transmission methods and control data are used in technologies like constant-voltage broadcasting, intelligent broadcasting, and FM broadcasting, the sound is still transmitted as an analog signal. The biggest problem is the inability to solve the signal attenuation and noise interference during transmission, limiting the transmission distance and the number of broadcast points. Cloud broadcasting systems use 4G networks, combined with IP telephony and traditional broadcasting, offering advantages such as high transmission speed, wide coverage, clear sound quality, and ease of operation. However, cloud broadcasting often requires a power distribution box for power distribution. Power distribution boxes are electrical equipment that can rationally distribute power, facilitate circuit opening and closing, and are characterized by small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. However, in practical use, it still has the following drawbacks:

[0003] 1. Utility model disclosure CN207977643U discloses a waterproof distribution box. The upper front end of the box body is connected to a bushing via a shaft. A sealing plate is fixedly connected to the outer side of the bushing. A rubber ring is adhered to the inner side of the sealing plate. The inner side of the rubber ring is tightly attached to the surface of the box body. A groove is provided inside the other end of the sealing plate. A first spring is fixedly connected to the inner side of the groove. A locking pin is fixedly connected to the other end of the first spring. A positioning sleeve is fixedly connected to the lower front end of the box body. The surface of the locking pin slides against the inner side of the positioning sleeve. The sealing plate or sealing cover of the distribution box is usually located on the side of the distribution box. Domestic water or rainwater can easily splash onto the side of the distribution box and the surface of the sealing cover. Although the rubber ring can ensure the waterproof effect, it also causes a certain gap between the distribution box and the sealing cover to accommodate the rubber ring. Although rainwater or domestic water will not penetrate, it is easy to accumulate in the gap for a long time, causing corrosion to the rubber ring and the outer shell of the distribution box. Moreover, after long-term use, the rubber ring will show signs of wear and aging, resulting in a decrease in the waterproof effect.

[0004] 2. To ensure normal operation, the distribution box usually needs to be equipped with a heat dissipation device to avoid overheating inside and affecting the stability of various components. Although the airflow driven by the fan can dissipate heat quickly, it can easily cause dust to enter the distribution box or accumulate on the filter surface, affecting the ventilation rate. In addition, in order to prevent rainwater from entering the distribution box through the filter, the area of ​​the filter is usually small. The small area of ​​the filter will further affect the airflow rate and reduce the heat dissipation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a rainproof and dustproof cloud broadcasting power distribution box. By using the power distribution box body and waterproof protective shell, it solves the problems of the power distribution box's sealing cover usually being located on the side of the power distribution box and sealed with a rubber ring. Rainwater can easily accumulate in the gap between the sealing cover and the power distribution box, causing corrosion to the rubber ring and the outer shell of the power distribution box. Moreover, after long-term use, the rubber ring will show signs of wear and aging. The heat dissipation ventilation opening of the power distribution box is also small, affecting the air flow rate and heat dissipation efficiency. Furthermore, the filter screen is easily clogged by external dust.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a rainproof and dustproof cloud broadcast power distribution box, including a power distribution box body and a waterproof protective shell. An installation plate is welded and fixed inside the power distribution box body. A cooling fan is snapped and fixed inside the power distribution box body. A filter element is snapped at the bottom of the cooling fan. A scraper is sleeved on the outer periphery of the filter element. A waterproof protective shell is slidably snapped at the top of the outer side of the power distribution box body.

[0008] The mounting plate allows for the installation and fixation of various cloud broadcasting electronic components. A cooling fan drives airflow to dissipate heat within the distribution box, ensuring the normal operation of the electronic components. A filter element filters the air passing through the cooling fan, preventing dust from entering the distribution box and affecting the electronic components. A scraper moves up and down to quickly remove dust from the filter surface; the large filter area allows for the passage of a large volume of air, ensuring efficient heat dissipation. A waterproof protective shell provides waterproof protection for the top and sides of the distribution box. The bottom of the waterproof protective shell is lower than the bottom of the distribution box, preventing rainwater from entering the box from the bottom due to gravity. This eliminates the need for a sealed structure and prevents rainwater accumulation, thus avoiding corrosion of the distribution box surface. A large ventilation opening at the bottom of the distribution box ensures rapid airflow.

[0009] Furthermore, a through hole and a vent are respectively opened on both sides of the bottom of the main body of the power distribution box, and a one-way valve is through and snapped onto one side of the bottom of the main body of the power distribution box. The one-way valve is located on the side of the through hole of the main body of the power distribution box, and the through hole and the vent are respectively located on both sides of the mounting plate.

[0010] The cooling fan draws air into the main body of the power distribution box through the vents and discharges it through a one-way valve. When cleaning the surface of the filter element, dust can quickly fall off through the vents. The mounting plate can be used to install and fix electronic components, ensuring stability during use.

[0011] Furthermore, sliders are welded and fixed to the top of both ends of the main body of the distribution box, and a mounting bracket is welded and fixed to the bottom of one side of the main body of the distribution box. The mounting bracket is located on the other side of the main body of the distribution box relative to the one-way valve.

[0012] The mounting bracket can connect and fix the distribution box to the environment, ensuring the stability of the distribution box during use.

[0013] Furthermore, a lifting cylinder is attached to the top of the cooling fan, and a telescopic tube is slidably attached to the bottom of the lifting cylinder. The telescopic tube is inserted through the top of the cooling fan and is attached to the upper side of the scraper. The cooling fan is attached to the inner wall of the main body of the power distribution box and one side of the mounting plate, and the cooling fan is suspended above the ventilation opening.

[0014] The cooling fan drives airflow, allowing air to pass through the filter element for filtration and then dissipate heat from the electronic components. This prevents dust from affecting the electronic components through the cooling fan. The filter element can also allow a large amount of air to pass through simultaneously, ensuring airflow speed and heat dissipation efficiency. After a period of time, the lifting cylinder moves the scraper up and down, scraping off the dust on the surface of the filter element and allowing it to be quickly discharged through the vents, improving ease of use.

[0015] Furthermore, the waterproof protective shell has an insulation groove inside, and sliding grooves are provided at both ends of the inner side of the waterproof protective shell, with the slider slidingly engaged with the inner side of the sliding groove;

[0016] The insulation groove protects the main body of the distribution box, preventing the rapid temperature fluctuations of the external environment from affecting the electronic components. The waterproof protective shell provides waterproof protection for the top and sides of the main body of the distribution box, and its bottom is lower than that of the main body of the distribution box. This prevents rainwater from entering the inside of the main body of the distribution box due to gravity, eliminating the need for a sealing structure and preventing the accumulation of rainwater, thus avoiding moisture corrosion of the distribution box surface. At the same time, a large ventilation opening can be opened at the bottom of the main body of the distribution box to ensure rapid airflow. When maintenance is needed, the waterproof protective shell can be quickly removed by pulling it upwards, making the operation simple and convenient.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of the distribution box's sealing plate or cover being located on the side of the distribution box, which is prone to splashing domestic water or rainwater onto the side of the distribution box and the surface of the sealing cover. Although rubber rings can ensure waterproofing, they also create gaps between the distribution box and the sealing cover to accommodate the rubber rings. While rainwater or domestic water cannot penetrate, it can easily accumulate in the gaps over time, causing corrosion to the rubber rings and the outer shell of the distribution box. Furthermore, with prolonged use, the rubber rings will wear and age, leading to a decrease in waterproofing effectiveness. The waterproof protective shell can waterproof the top and sides of the distribution box body, and its bottom is lower than the bottom of the distribution box body. Rainwater cannot easily overcome gravity to enter the inside of the distribution box body from the bottom, eliminating the need for a sealing structure and preventing the accumulation of rainwater, thus avoiding moisture corrosion on the surface of the distribution box.

[0019] 2. This utility model solves the problem of power distribution boxes typically requiring heat dissipation devices to prevent overheating and ensure stable operation of components by incorporating a main body and a waterproof protective shell. While fans can quickly dissipate heat, they also allow dust to enter the box or accumulate on the filter surface, affecting ventilation. Furthermore, to prevent rainwater from entering through the filter, the filter area is usually small, further impacting airflow and reducing heat dissipation efficiency. The waterproof protective shell prevents rainwater from entering through the bottom of the main body, allowing for larger ventilation openings to ensure rapid airflow. The large surface area of ​​the filter element filters the air passing through the cooling fan, preventing dust from affecting electronic components and maintaining airflow. After a period of use, a scraper moves up and down to remove dust from the filter surface, allowing it to be discharged through the ventilation openings, further ensuring airflow.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-6 As shown, this utility model is a rainproof and dustproof cloud broadcast power distribution box, including a power distribution box body 1 and a waterproof protective shell 2. An installation plate 101 is welded and fixed inside the power distribution box body 1. A cooling fan 103 is snapped and fixed inside the power distribution box body 1. A filter element 110 is snapped at the bottom of the cooling fan 103. A scraper 109 is sleeved on the outer periphery of the filter element 110. The waterproof protective shell 2 is slidably snapped at the top of the outer side of the power distribution box body 1.

[0030] Electronic components are installed on the front of mounting plate 101. Waterproof protective shell 2 is fitted onto the upper side of the main body 1 of the distribution box, and the cloud broadcasting distribution box is installed in a suitable position. When the cloud broadcasting distribution box is in normal use, when the temperature inside is too high, the cooling fan 103 drives the air to flow. The air cools the electronic components through the vent 106 and filter element 110, and then the hot air is discharged through the one-way valve 102. When rain or domestic water is splashed on the surface of the cloud broadcasting distribution box, the waterproof protective shell 2 protects the main body 1 of the distribution box. The water falls directly down the surface of the waterproof protective shell 2 under the action of gravity. After a period of use, the lifting cylinder 111 drives the scraper 109 to move up and down, scraping off the dust on the surface of the filter element 110. The dust is discharged through the vent 106 under the action of gravity.

[0031] Among them, such as Figure 1-5 As shown, a wire passage hole 104 and a ventilation opening 106 are respectively opened through the bottom sides of the main body 1 of the distribution box. A one-way valve 102 is snapped through one side of the bottom of the main body 1 of the distribution box. The one-way valve 102 is located on one side of the wire passage hole 104 of the main body 1 of the distribution box. The wire passage hole 104 and the ventilation opening 106 are respectively located on both sides of the mounting plate 101. Slider 105 is welded and fixed to the top of both ends of the main body 1 of the distribution box. A mounting bracket 107 is welded and fixed to the bottom of one side of the main body 1 of the distribution box. The mounting bracket 107 is located on the other side of the main body 1 of the distribution box opposite to the one-way valve 102.

[0032] A lifting cylinder 111 is attached to the top of the cooling fan 103. A telescopic tube 108 is slidably attached to the bottom of the lifting cylinder 111. The telescopic tube 108 is inserted through the top of the cooling fan 103 and is attached to the upper side of the scraper 109. The cooling fan 103 is attached to the inner wall of the main body 1 of the power distribution box and one side of the mounting plate 101. The cooling fan 103 is suspended above the top of the ventilation opening 106.

[0033] When installing the cloud broadcast power distribution box, the electronic components are fixed on the upper side of the mounting plate 101, and the power cord is inserted through the through hole 104. The power distribution box body 1 is installed in a suitable position by the mounting bracket 107. When in use, when the temperature inside the power distribution box body 1 rises to the threshold, the cooling fan 103 drives the air into the power distribution box body 1 through the vent 106, and the air is filtered by the filter element 110 and then used to cool the electronic components. Finally, the hot air is discharged through the one-way valve 102. After a period of time, the extension and retraction of the telescopic tube 108 is driven by the lifting cylinder 111, which further drives the scraper 109 to move up and down, scraping off the dust on the surface of the filter element 110 and allowing the dust to be quickly discharged through the vent 106.

[0034] Among them, such as Figure 1 , 2 As shown in Figure 6, the waterproof protective shell 2 has an insulation groove 202 inside, and sliding grooves 201 are provided at both ends of the inner side of the waterproof protective shell 2. The slider 105 is slidably engaged with the inner side of the sliding groove 201.

[0035] After the electronic components are installed, the waterproof protective shell 2 is inserted from the top of the power distribution box body 1, so that the waterproof protective shell 2 is fitted onto the outside of the power distribution box body 1. The heat insulation groove 202 protects the power distribution box body 1 and prevents the temperature of the electronic components from being affected by the outside temperature. When rain or domestic water is splashed on the surface of the cloud broadcast power distribution box, the waterproof protective shell 2 protects the power distribution box body 1, and the water falls directly down the surface of the waterproof protective shell 2 under the action of gravity.

[0036] The specific working principle of this utility model is as follows: When installing the cloud broadcast power distribution box, the electronic components are fixed on the upper side of the mounting plate 101, and the power cord is inserted through the through hole 104. The power distribution box body 1 is installed in a suitable position through the mounting bracket 107. The waterproof protective shell 2 is inserted from the upper side of the power distribution box body 1, so that the waterproof protective shell 2 is sleeved on the outside of the power distribution box body 1. The heat preservation groove 202 protects the power distribution box body 1, avoiding the rapid influence of the external temperature on the temperature of the electronic components. When the temperature inside the power distribution box body 1 rises to the threshold, the cooling fan 103 drives... Dynamic air enters the main body 1 of the distribution box through the vent 106, is filtered by the filter element 110, and then dissipates heat from the electronic components. Finally, the hot air is discharged through the one-way valve 102. After a period of time, the extension and retraction of the telescopic tube 108 is driven by the lifting cylinder 111, which further drives the scraper 109 to move up and down, scraping off the dust on the surface of the filter element 110 and allowing the dust to be quickly discharged through the vent 106. When rain or domestic water is splashed onto the surface of the cloud broadcasting distribution box, the waterproof protective shell 2 protects the main body 1 of the distribution box, and the water falls directly down the surface of the waterproof protective shell 2 under the action of gravity.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
