Description

A Ventilation System for Playground Buildings in Weather

technical field

The utility model relates to the field of ventilation systems, in particular to a ventilation system for wind and rain playground buildings.

Background technique

At present, in rainy weather, teachers and students are often unable to attend classes or activities on the playground, and the range of activities for teachers and students is relatively small.

Utility model content

The purpose of the utility model is to provide a ventilation system for playground buildings in wind and rain, which can keep the playground buildings warm and complete the ventilation of the playground buildings, solve the problem that the playground cannot be used for activities in wind and rain, and enrich the life of teachers and students. Spare-time life, improve the overall physical fitness of teachers and students.

The technical solution adopted by the utility model to solve the technical problem is: a ventilation system for wind and rain playground construction, including an outer wall, a water pump and a fan, a roof is set on the top of the outer wall, an inner wall is set on the inner side of the outer wall, and the outer wall and the inner A cavity is formed between the walls, a backing plate is set at the inner bottom of the inner wall, and a mesh heat dissipation pipe is arranged at the lower part of the cavity and inside the backing plate. The heat dissipation pipe is connected to the water pump, the water pump is connected to the water source, and the fan is connected to the bottom of the cavity through a pipeline. , There are several ventilation holes on the top of the inner wall, the width or diameter of the ventilation holes is less than 10mm, and the ventilation holes communicate with the cavity.

The technical scheme adopted by the utility model in order to further solve the technical problem is: the roof is arc-shaped with an opening downward, and a filter screen is arranged between the roof and the outer wall. Horizontal fixed platforms and vertical guide rails are arranged on the outer walls on both sides of the outer wall, and a baffle plate that can slide up and down along the guide rail is installed on the guide rail. A vertical telescopic rod, the movable end of the telescopic rod is connected with the baffle, and the telescopic rod can control the baffle to slide upward to the outside of the filter screen.

The beneficial effects of the utility model are: the utility model can make the outer wall and the roof shelter the teachers and students from the wind and rain, so that the teachers and students can still have a wide activity field in the wind and rain, and the water pump is connected with the heating pipeline when the weather is cold. When the weather is hot, the water pump is connected to the tap water pipeline or the reclaimed water source, so that the heat dissipation pipe can pass through the inner wall to complete heat exchange with the room, ensuring that the room is warm in winter and cool in summer. The fan can extract the outside air, make it enter the cavity, and after completing the heat exchange with the cooling pipe, it becomes hot or cold air, and enters the room through the ventilation hole on the upper part of the inner wall, which can not only assist the cooling tube to complete the heat exchange with the room, but also Ensure indoor air circulation to achieve ventilation effect. The ventilation hole is located on the top of the inner wall and the width or diameter is less than 10mm. This structure makes the airflow generated by the ventilation hole smaller when the air is sucked or supplied. Since there are multiple ventilation holes, the sound of the air flowing through the ventilation hole is relatively small. , and the position of the ventilation hole is relatively high, which will not cause sensory and noise impact on indoor teachers and students.

Detailed ways

A ventilation system for wind and rain playground buildings, as shown in Figure 1, includes an outer wall 1, a water pump 6 and a fan 7, the upper part of the outer wall 1 is provided with a roof 2, the inner side of the outer wall 1 is provided with an inner wall 3, the outer wall 1 and the inner A cavity 4 is formed between the walls 3, a backing plate 5 is arranged at the bottom of the inner side of the inner wall 3, and a mesh heat dissipation pipe 8 is arranged in the lower part of the cavity 4 and the backing plate 5, and the heat dissipation pipe 8 is connected to the water pump 6, and the water pump 6 is connected to the water source The fan 7 communicates with the bottom of the cavity 4 through pipelines, and several ventilation holes 9 are provided on the top of the inner wall 3, the width or diameter of the ventilation holes 9 is less than 10mm, and the ventilation holes 9 communicate with the cavity 4. This structure can make the outer wall 1 and the roof 2 shelter teachers and students from wind and rain, so that teachers and students can still have a wide activity field in wind and rain. It is connected with the running water pipeline or the reclaimed water source, so that the cooling pipe 8 can pass through the inner wall 3 to complete heat exchange with the room, ensuring that the room is warm in winter and cool in summer. Fan 7 can extract outside air, make it enter cavity 4, and after completing heat exchange with radiating pipe 8, become hot wind or cold wind, enter indoor by vent hole 9 on inner wall 3 top, can assist radiating pipe 8 to complete and indoor. The heat exchange can ensure the indoor air circulation and achieve the ventilation effect. Water pump 6 and blower fan 7 all can be two, and two water pumps 6 and blower blower 7 are positioned at exterior wall 1 both sides respectively, and two water pumps 6 pump water one, and one draws water, is convenient to the water circulation in heat dissipation pipe 8. One of the two fans 7 is exhausting and the other is blowing, which is convenient for indoor air circulation. The ventilation hole 9 is located on the upper part of the inner wall 3 and has a width or diameter less than 10mm. This structure makes the airflow generated by the ventilation hole 9 smaller when drawing or blowing air. Since there are multiple ventilation holes 9, the air flows through the ventilation hole 9 , the sound is relatively small, and the position of the air vent 9 is relatively high, which will not affect the senses and noise of teachers and students in the room.

As shown in FIG. 2 , the roof 2 is arc-shaped with an opening downward, and a filter screen 10 is arranged between the roof 2 and the outer wall 1 . This structure can make the sundries and rainwater on the roof 2 easy to move, and avoid rainwater and sundries from accumulating on the roof 2 . The filter screen 10 can filter the dust and sundries that enter the room from the outside.

As shown in Fig. 2 and Fig. 3, horizontal fixed platform 11 and vertical guide rail 12 are all set on the outer wall of described outer wall 1 both sides, and the baffle plate 13 that can slide up and down along guide rail 12 is installed on guide rail 12, and The upper part of the plate 13 is an arc with an opening downward, and a vertical telescopic rod 14 is arranged on the fixed platform 11. The movable end of the telescopic rod 14 is connected with the baffle plate 13, and the telescopic rod 14 can control the baffle plate 13 to slide upwards to the filter screen 10 outside. This structure can control the baffle plate 13 to close the filter screen 10 through the expansion and contraction of the telescopic rod 14, so that the room can be closed in windy and dusty weather and when the temperature is low, preventing external dust from entering the room and preventing indoor heat from escaping to the outside. The telescopic rod 14 is an existing telescopic structure such as a hydraulic cylinder or an electric push rod.
