Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation equipment, in particular to a ventilation equipment for construction engineering management. Background Art

[0002] In construction project management, ventilation equipment plays a vital role. Its importance is reflected in improving indoor air quality. It can effectively expel indoor polluted air, introduce fresh air, and reduce the concentration of pollutants in the air, such as dust, bacteria, formaldehyde, etc., to provide a healthy and comfortable environment for indoor people. Especially in crowded places such as offices, shopping malls, hospitals, etc., good ventilation can reduce the risk of disease transmission; it can also regulate indoor temperature and humidity, and remove excess heat and moisture indoors through ventilation to keep indoor temperature and humidity within an appropriate range. In summer, it can lower the indoor temperature, reduce the use of air conditioning, and reduce energy consumption. In winter, it can prevent the indoor air from being too dry; at the same time, it improves the safety of the building. Good ventilation can reduce the concentration of smoke and toxic gases in the event of a fire, providing favorable conditions for the evacuation of personnel. For some special buildings, such as basements, warehouses, etc., ventilation equipment can also prevent the accumulation of flammable and explosive gases and reduce the risk of explosion.

[0003] However, in the existing technology, most ventilation equipment cannot provide long-term and effective cleaning effect on the filter plate when supplying air to the indoor environment, which may cause the filter plate to become clogged after long-term use. This blockage not only affects the operating efficiency of the equipment, but may also lead to a decline in indoor air quality and increase the health risks of users. Summary of the Invention

[0004] The purpose of the utility model is to provide a construction engineering management ventilation device, which is equipped with a filtering mechanism to shake off the dust accumulated on the filter plate, avoid excessive dust accumulation affecting the filtering effect, and maintain a long-term effective and clean ventilation environment. It solves the problem that most ventilation equipment cannot provide a long-term and effective cleaning effect on the filter plate when supplying air to the indoor environment, resulting in the filter plate being clogged after long-term use. This blockage not only affects the operating efficiency of the equipment, but may also lead to a decline in indoor air quality, increasing the health risks of users.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a construction engineering management ventilation device, comprising a bottom plate, on which a ventilation mechanism and a filtering mechanism are arranged.

[0007] The ventilation mechanism includes a connecting shell fixedly connected to the top surface of the bottom plate, the rear side of the connecting shell is fixedly connected to motor 1, the output end of the motor 1 is fixedly connected to rotating rod 1, the outer wall of the rotating rod 1 is fixedly connected to a plurality of turbine blades, the outer wall of the connecting shell is connected to an air outlet pipe, the air outlet pipe is fixedly connected to the connecting shell, one end of the air outlet pipe away from the connecting shell is fixedly connected to a bellows 1, the front side of the connecting shell is connected to an air inlet pipe, the front end of the air inlet pipe is connected to a connecting pipe, the air inlet pipe is fixedly connected to the connecting pipe, the inner wall of the connecting pipe is slidably connected to a filter plate, the front side of the connecting pipe is connected to a bellows 2, and the connecting pipe is fixedly connected to the bellows 2.

[0009] Furthermore, one end of the spring 1 is fixedly connected to the connecting block, and the other end of the spring 1 is fixedly connected to the fixing frame 1.

[0010] Furthermore, two fixing plates are fixedly connected to the inner wall of the connecting pipe, a push rod is slidably passed through the two fixing plates, and a rack is fixedly connected to the outer wall of the push rod.

[0011] Furthermore, a rubber pad is fixedly connected to the front end of the push rod away from the rack, a second spring is wound around the outer wall of the push rod, and the rubber pad is in contact with the filter plate.

[0012] Furthermore, one end of the second spring is fixedly connected to the rubber pad, and the other end of the second spring is fixedly connected to the fixing plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. By providing a ventilation mechanism, the motor on the connecting shell is driven to rotate the rotating rod, and the rotating rod drives multiple turbine blades to rotate, so that the external air is sucked into the interior of the connecting shell through the air inlet pipe. Using this method, not only the speed of air circulation can be effectively improved, but also the freshness of the air can be maintained in a specific working environment. Under the action of multiple rotating turbine blades, the air is quickly pushed to the air outlet pipe for discharge, thereby enhancing the overall ventilation effect, thereby ensuring that the indoor environment reaches an ideal temperature and humidity. At the same time, the filter plate on the connecting pipe can filter the dust in the air to prevent the dust in the external air from affecting the indoor environment and improving the air quality.

[0016] 2. By providing a filtering mechanism, with the cooperation of the fixing frame 1, the sliding rod, the connecting block and the spring 1, the reset spring 1 drives the sliding rod to fix the filter plate inside the connecting pipe. At the same time, the two sliding rods can be pulled outward, so that the filter plate can be quickly replaced, avoiding damage to the filter plate after long-term use and affecting the filtering effect. In the process of ventilation, the motor 2 can be driven to drive the rotating rod 2 to rotate, so that the half gear on the rotating rod 2 drives the rack to move backward for a distance until the half gear and the rack are no longer engaged. Under the reset action of the spring 2, the rubber pad hits the filter plate, and the filter plate vibrates slightly, which shakes off the dust accumulated on the filter plate, avoiding excessive dust accumulation affecting the filtering effect and maintaining a long-term effective and clean ventilation environment.
