Technical Field

[0001] The utility model relates to the technical field of heat dissipation of electronic bus stop signs, in particular to a ventilation and heat dissipation device for bus stop signs. Background Art

[0002] The electronic bus stop sign is a common sign used to display bus route information and time information. The use of electronic bus stop signs has promoted the convenience of transportation. Since there are many internal components in the electronic bus stop sign, it will emit a lot of heat after working for a long time. If the heat is not discharged in time, it will affect the service life of the electronic bus stop sign. Therefore, a heat dissipation device is needed to dissipate the heat.

[0003] For example, the authorization announcement number "CN215819128U" is named a bus electronic bus stop sign heat dissipation device. Although it can cool down the inside of the bus electronic bus stop sign in time when the temperature inside the bus electronic bus stop sign does not meet the set value, avoiding the problem of damage to the bus electronic bus stop sign due to untimely heat discharge, thereby improving the service life of the bus electronic bus stop sign, but it still needs to be placed outdoors for passengers to observe, so the service life will be relatively long. After too much sun and wind, it is easy to cause aging of the driving screw, which in turn leads to a decrease in the sensitivity of the temperature detection equipment. Moreover, the bus electronic bus stop sign needs to be kept in the started state at all times, which greatly affects the use of the bus electronic bus stop sign heat dissipation device, and ultimately reduces the service life of the bus electronic bus stop sign heat dissipation device.

A bus stop sign information board is fixedly installed at the front end of the bus stop sign body, a leak-proof plate is fixedly installed at the top of the bus stop sign body, and a water tank is fixedly installed above the leak-proof plate.

[0006] Preferably, a ramp is fixedly installed inside the water tank, a water pipe is fixedly connected to the lower end of the water tank, a control valve is fixedly installed on the end of the water pipe, a filter is fixedly installed inside the water pipe, the other end of the water pipe is fixedly connected to a drain pipe, and a drain valve is fixedly installed inside the drain pipe.
