Description

Safe type machine case ventilation unit for frequency conversion water supply equipment

Technical Field

The utility model relates to a frequency conversion is quick-witted case ventilation unit for water supply equipment specifically indicates a frequency conversion is safe type machine case ventilation unit for water supply equipment.

Background

Along with the advance of urbanization process, the city is bigger and bigger, and originally the residential quarter that running water pressure can satisfy the demand, the pressure drop appears, and the demand of owner can not be satisfied completely in the direct supply of partial residential quarter running water supply pipe network. Therefore, the tap water supply network of some residential districts is added with water supply equipment for secondary water supply and pressurization.

With the continuous progress of the technology, the frequency conversion water supply equipment with intellectualization and energy conservation is applied. The existing frequency conversion water supply equipment generally comprises a machine case, wherein the upper part of the machine case is used for installing electric control system facilities, and the lower part of the machine case is used for installing hardware facilities such as a water suction pump, a standby pump, a water inlet and outlet pipeline and the like. Hardware facilities such as electrical system facility and suction pump all can produce certain heat at the operation in-process, in order to ensure that the operation of supplying water can effectively go on continuously, all can be provided with corresponding ventilation unit on the quick-witted case for the frequency conversion water supply equipment now specially. Most of the traditional case ventilation devices are that ventilation openings are directly formed at corresponding parts of a case, and then a filtering mechanism device is arranged at the ventilation openings of the case. Such a ventilation device does not have a function of preventing rain water from splashing, and is insufficient in safety. After the filtering mechanism is damaged by external force, the children or other people who want to destroy the equipment can touch the electrical elements or the water pump and other power parts in the case, so that great potential safety hazards exist. Therefore, the existing case ventilation device can be additionally provided with the air inlet cover at the periphery of the ventilation opening of the case, the effect of preventing rain water from splashing is realized through the arrangement of the air inlet cover, and a certain isolation effect can be realized, so that personnel can be prevented from touching electrical elements or power parts such as a water suction pump and the like in the case. But in order to ensure the ventilation effect, the current air inlet cover must be provided with sufficient ventilation hole again, and the setting of ventilation hole leads to personnel only to hand the shaft-like thing and just can see through the ventilation hole to contact the part in the quick-witted case, has the potential safety hazard equally. In addition, most of the existing air inlet covers are directly locked and installed on the ventilation opening of the case through locking bolts, so that the air inlet covers can be easily disassembled, the probability that personnel contact parts in the case is further increased, and potential safety hazards are further increased.

Consequently, design a section and can prevent effectively that the air inlet cover from being demolishd, and just even handheld shaft-shaped thing also can't see through the ventilation hole and remove the part that contacts quick-witted incasement to can further promote rain-proof water-proof effect's frequency conversion water supply equipment is with safe type machine case ventilation unit does the utility model discloses a research purpose.
